Description
W 097/48560 PCT~US96116733 ADH~SIVE TAPE STRIP AND TAPE FLAG PADS
Wl l ~l CENTER TABBED LEADER STRIP
Field of the Invention 5The invention broadly relates to pads of adhesive tape strips and adhesive tape fiags. More spe~ifi~ y, the invention relates to leader strips used to initiate dis~,~ ns;llg of individual adhesive tape strips and adhesive tape flags from such pads.
B~ckground 10Rolls of adhesive tape and pads of adhesive tape flags are widely used throughout the world. The most widely used variety of adhesive tape flags are those which utilize a reposition~le adhesive.
Rolls of reposition~ble tape, such as the "Post-It~)" brand rolls of reposition~' tape sold by Milulesota Mining and M~mlf~ctl~ring of Saint Paul, 15 M;~nPsola, have a variety of uses, incl~rlin~ the mountin~ of customized signage sheets to a window (e.g. "Dog Lost Poster") and ~ ulltlng easel pad pages to a wall after they have been removed from the easel pad.
Pads of repocitioDable tape flags, such as the widely used "Post-It~)" brand tape flags sold by M;..nesota Mining and M~mlf~ ring of Saint Paul, Minnesota 20 have become a staple office supply product throughout the world.
A variety of d;s~ se. ~ have been developed for the pads of adhes*e tape fiags. These ~ Je~ include (i) disposable and refillable dispensers, (ii) shuttlin~
and nol-.~h..~ 8 di~pe. s~, (iii) high volume/high profile and low volume/low profile dixpc~ s, (iv) single pad and ml~lfiple pad ~ic~C~ P ~, (v) hand held and mountable 25 dispensers, etc.
One co.---.-on feature found on most pads of adhesive tape flags, regardless of the type of ~ e- used, is the pre3e.,ce of some type of leader strip used to initiate pe~,c;i~ of individual flags from the pad. While a variety of useful leader strip confi~lrations have been developed, a con~ Jil~e need exists for a leader strip 30 confi~ation which is simple and ;l.~ -l e c;~e to m~nuf~ct~re and install, useful with a variety of diael~nl types of di~l,c ..~, ~, reliable, and easy for cQn~u~ to use.
CA 022~7262 1998-12-02 W 097/48560 PCTrUS96/16733 Summary of the Invention We have discovered a unique leader tape confi~ration for use in connection with pads of adhesive tape strips and adhesive tape flags.
5 Adhesive Tape Strip Pad The adhesive tape strip embodiment of our invention comprises a leader strip ~n~rhed to a pad of adhesive tape strips. The pad cor.ll,.;ses a plurality of superimposed individual tape strips.
The first major surface of each tape strips is coated with a low adhesion 10 baçl~ci7e to f~r.ilit~te separation ofthe individual strips, while the second major surface of each tape strip is coated with an adhesive. The pad in~ des an uppermost tape strips with an exposed first major surface of the uppermost tape strips, and a lowermost tape strips with an exposed second major surface of the lowermost tapestrip.
The leader strip is aligned with and superimposed over a position ofthe exposed first major surface of the uppermost tape strip. A tacky first longit~l~lin~l end portion of the leader strip is positioned prox;. . .~le the first lon~tl1din~l edge of the pad and adhesively bonded to the exposed first major surface of the uppermost tape strip, while a ncrt~cl~y second longit~lrlin~l end portion ofthe leader strip is 20 positioned intermPdi~te the first and second longitudin~l edges of the pad so as to form a nnnt~cL y centrally positioned pull tab portion.
The pull tab portion does not bond to the pad and can be readily grasped for initiating dispensing of individual tape strips from the pad. The pull tab portion is preferably positioned so that the free longitudin~l end of the pull tab portion is 25 longit~l~in~lly spaced less than about one fifth the complete longih~(lin~l length of the pad away from the lateral axis of the pad.
Contin.led dispensing of the individual tape strips is achieved by (i) adhering the second major surface of each individual tape strip in the pad to the first major surface of an imme~ tPly underlying tape strip at a first adhesive sl- en~lh, except for 30 a selected area plo,~;...~te one ofthe lon~it~l~lin~l edges ofthe strip where the tape strip is adhered to the first major surface of the ;~...--e~ lely underlying strip at a lower adhesive strength, and (ii) configllring the individual tape strips in the pad so W 097/48560 PCTrUS96/16733 that s~lcces~ive strips in the pad are positioned with the lower adhesive ~1l er,glll area of each strip all~ aling between the first and second longitlldinAl edges of the pad.
The diLrerence in adhesive strengths is s~leeted so that the lower adhesive sllellglh portion of each strip will d~ e from the ;~ ely underlying strip when an5 immedi~tely ov~,.ly;ng strip is peeled from the pad.
The change in adhesive sl,~nglh can be achieved by several meel~nic,".c inr~ 1ing (i) coating only a portion of the second surface of each tape strip with adhesive, (ii) pattern coating the adhesive onto the second surface of each tape strip so as to coat less adhesive onto a portion of the second surface of each tape strip, (iii) 10 pattern coating a low adhesion b~A.~l~ci7e onto the first surface of each tape strip so as to coat less b~A.~ I ~; e onto a portion of the first surface of each tape strips, etc.
Adhesive Tape Flag Pad The adhesive tape flag embodiment of our invention is sul.sl ~ Ally similar to 1 S the adhesive tape strip embodim~nt and comprises a leader strip ~tt~çhed to a pad of adhesive tape flags. The pad of flexible adhesive tape flags comprises a plurality of s.lpcl;~..posed individual tape flags which form a unitary pad having an uppellllost tape flag with an eAI.03ed first major s~lrfA~e, and a lowermost tape flag with an exposed second major surface. The first major surface of each tape flag has (i) a first 20 tacky area pro~ te a first longit.l-linAl end of the flag which is coated with a repositiQn~ble adhesive, and (ii) a second nont~y area proximAte a second lon~tu~in~l end of the sheet.
The leader strip is aligned with and supc,i-..l,osed over a portion ofthe exposed first major surface of the uppermost tape strip. A tacky first lonpitudinAI
25 end portion ofthe leader strip is positio~ed p-o,.;.~ e the first longitu~inAl edge of the pad and adhesively bonded to the exposed first major surface ofthe uppermosttape flag plox;... ~le the nont~c~y second longit~ldinAI end ofthe uppermost tape flag.
A nont~el~y second lonpit~ inAl end portion of the leader strip is positioned i-lle-.~.F,d;~te the first and second longit~ inAI edges ofthe pad so as to form a 30 nr)nt~cl~y centrally pos;l;oned pull tab portion.
The pull tab portion does not bond to the pad and can be readily grasped for initiAting dispensing of individual tape flags from the pad. The pull tab portion is CA 022s7262 1998-12-02 W 097/48560 PCTrUS96/16733 preferably positioned so that the free lon~it~lrlinAl end of the pull tab portion is longit~ldin~lly spaced less than about one fifth the colllplcte longjt~ in~l length of the pad away from the lateral axis of the pad.
Contin~led ~lisp~n.~;ng ofthe individual tape flags is achieved by (i) adhering the tacky first longit~ inql end ofthe second major surface of each individual tape flag in the pad to the first major surface of an immediAtely underlying tape flag, and (ii) confi~lring the individual tape flags in the pad so that successive flags in the pad are positioned with the first lon~ib~inal end of each flag alternating belween the first and second longitlldin~l edges of the pad.
Di;,~e ~cr The adhesive tape strips pads and adhesive tape flag pads can be conveniently dispensed from a dispenser comprising an enclosure dçfining a retention chamber into which the pad is inserted. The çnrlQs~lre has a base, side walls, and a top with a centrally positioned ope.ullg having a width which typically extends subs~ lly the entire width of the retention ch~.ber and a length which is large enough to permit the passage of a tape strip or flag through the opening yet small enough to prevent the full length of a tape strip or flag from falling back into the retention cl,~llbel once a portion of the tape strip has been pulled through the opening.
A cover may optionally be provided for purposes of sealing the opening through the top of the enclosure and exposing the leader strip when the cover isremoved.
The dispenser may be constructed as a single use dispenser to be discarded when the pad of tape strips or tape flags within the ret~ntion chamber are ~,Yh~llste~
or a rçfillAble di~ er e~luipped with a ~echA~ic~lop~l b'e for allowing accesses to the retention ch~llber for purposes of inserting a new pad into the chamber.
The dispenser may also be constructed as a .ehllttling or noneh~lttlin~
dispenser, with the length of the retention ch~lbe- either oversized to permit back and forth eh~ in~ of the pad within the chamber as individual tape strips or tape flags are pulled from the pad, or sized to accommoclate the pad with s~ A~ lly no space for back and forth ~h~ll llinp of the pad within the cl~ -ber as individual tape strips or tape flags are pulled from the pad.
W 097/48560 PCTrUS96/16733 Method of Making Adhesive Tape Strips and Flags The invention in~ dç$ a method of making the centrally tabbed adhesive tape 5 strips and adhesive tape flags (here;n~l~r l.,fe~ ced collectively as "adhesive tape") comprising the steps of:
(1) CO~ lg a master pad co~ ni..g a plurality of sul~.i"lposed adhesively coated sheets in a machine direction, with each sheet having (i) a tacky first major surface; (ii) a nontacly second major surface, and (iii) first and second sides;(2) cGIl~c;ying a continllollc length oftabbing material in the m~hine direction, with the tabbing material having (i) first and second sides; (ii) a first major surface having r ~ntaCL y side "la~gh~s and a tacky central area between the side I~lUgillS coated with an adhesive, and (iii) a nol~t~cl~y second major surface;
(3) I~...;n~til~ the first major surface of a length of the tabbing material to the 15 second major surface of the ul~pe~ ost sheet on the master pad, with the tabbing materi~l offset from both sides ofthe master pad so as to define uncovered side algllls on the master pad;
(4) cutting the tabbed master pad in the m~rhin~ direction within the tacky portion ofthe tabbing material so as to produce contin~o~c ...~.hi~e direction lengths 20 of tape having (i) a first side portion covered with the adhesive portion of the tabbing material, (ii) a second side portion free from tabbing material, and (iii) a nontac~y tab ...e~;~le the first and second sides of the tape formed from one of the nont~
side l"&~ins on the tabbing material; and (5) cutting the tabbed master pad in the ll~ c direction so as to produce 25 tape of a desired width.
When two or more lengths oftabbing Illaltl;al are l~min~ted to the master pad ofthe adhesive sheets, the m~m~f~ct~ring process must comply with two ad~ition~lte4ui~",t"1s. First, the lengths oftabbing m~tÇ~l must be offset from each other so as to define interrnedi~te gaps b~l~een the lengths of tabbing material 30 on the master pad which are not covered with tabbing material. Second, the tabbed master pad must be cut in the maçhine direction bet~n~,en adjac~t pairs of nontacky side Illargins from dilre ~, nt Iengths of tabbing m~te~

As utilized herein, inc~ ~ the claims, the tenn "nontacky" means lack of 20 adhesive tack at room temperate and pressure.
The term "repositionrt'E adhesive" is a tenn of art which is utilized herein in accoldance with its standard indust~ m~ning Broadly, a repositic-n~hle adhesive is an adhesive which permits typical tape strip and tape flag substrates, such as paper and polymeric films, to be repe~tedly ~tt~ched to and removed from various s~rf~ces, 25 such as paper, without ~igrific?nt loss in adhesive strength, without leaving adhesive residue upon the surface, and without destruction of the s~s~la~e.
The terrn "tape flag" is a widely used term of art which is utilized herein in accordance with its standard industry m~ni~ Broadly, a tape flag is a flexible substrate with a first end of a first major surface coated with an adhesive, usually a 30 reposition~ble adhesive, and a nont~c~y second end of the first major surface. Tape flags are usually rect~ng~ r in shape and about 1 to 6 cm wide and about 3 to 10 cm long although other sizes and shapes are certainly possible. The nontacky end of the CA 022~7262 1998-12-02 W O 97/48560 PCTrUS96/16733 substrate is typically color coded or printed with indicia. A variety of means can be employed to render the second end ofthe first major surface nsnt~~~y inclll~ing (i) limiting application of the adhesive coating to only the first end of the first major surface, or (ii) allowing the adhesive coating to be applied to the entire surface area 5 of the first major surface and then applying a nontacky material, coating or liner over the adhesive at the second end.
The term "tape strip" is a widely used term of art which is utilized herein in accoldance with its standard industry me?nine Broadly, a tape strip is a flexible substrate with a first major surface coated with an adhesive. Tape strips are usually rect~n~ r in shape and about 1 to 10 cm wide and about 3 to 20 cm long, most frequently about 1 to S cm wide and about 3 to 10 cm long, although other sizes and shapes are certainly possible.
Construction A unique leader strip 60 is provided for use on adhesive tape strips pads 20 and adhesive tape flag pads 120. The leader strip 60 is simple and inexpensive to m~mlf~ctllre and install on the pads, useful with a variety of di~~ types of dispensers, reliable, and easy for con.~l~mers to use.
Adhesive Tape Strip Pad Individual Tape Strips As shown in Figures 1 through 9, the adhesive tape strip embo~liment of the invention comprise a leader strip 60 att~rhed to a pad 20 of adhesive tape strips 30.
The adhesive tape strip pad 20 is comprised of a plurality of superimposed individual tape strips 30. The tape strips 30 are constructed from a flexible substrate 30s, such as paper, polyethylene, poly~.ol.ylene, polyethylene terephth~l~te, etc. The individual tape strips 30 define a longit~din~l axis 30x and a lateral axis 30y and have a first longitudin~l end 31, a second lon it ldin~l end 32, a first lateral side 33, a second lateral side 34, a first major surface 35, and a second major surface 36. The first major surface 35 of each tape strip 30 is coated with a low adhesion bac~i7e 50 to farilit~te separation of the superimposed individual strips 30. The second major W O 97/48560 PCT~US96/16733 surface 36 of each tape strip 30 is coated with an adhesive 40, such as a reposition~hle adhesive or a pe.lllane.ll pressure sensitive adhesive.
Tape Strip Pad The pad 20 of adhesive tape strips 30 defines a loneih1~in~1 axis 20x and a 5 lateral axis 20y, and has a first longjt~ in~l edge 21 and a second longitu~inAl edge 22. The pad 20 has an uppemmost tape strip 30u and a lowermost tape strip 30p.
The pad 20 is fomled from any desired number of individual adhesive tape strips 30, p-~,f~l. bly b~ .een about 10 and 120 tape strips 30, by adhering the second major surface 36 of each individual tape strip 30 to the first major surface 35 of immPdi~tPly underlying tape strip 30. The first major surface 35 of the tape strips 30 are pattem coated with a low adhesion ba~ e 50 with a first pattern coating provided over a first area 51 and a second pattern coating provided over a second area 52 of the adhesive tape strips 30. The first pattem coating permits a higher ~lhesi~n stlellgll- than the second pattern coating (i.e., the pattern ofthe first pattem 1 S coating covers less surface area than the pattern of the second pattern coating). The individual adhesive tape strips 30 are then stacked in a Z pattern with succes~;ve strips 30 in the pad 20 positioned with the high ~ Psion pattern coated area 51 of each strip 30 allelllalillg be~ the first 21 and the second 22 longjtudtn~l edges of the pad 20. The di~el e"ce in adhesive strength between the high adhesion pattem20 coated area 51 and the low adhesion pattern coated area 52 is selected so that the lower adhesive sh~n2~ portion 52 of each strip 30 will~el~min~te from the ;....ne.l;~lçly unde~ g strip 30 when an ;,,,,,,ç~ Ply overlying strip 30 is peeled from the pad 20.
The change in adhesive ~ ,nglh can also be aç~;Avcd by several other 25 ,n~chAn..c.n.c, inclu~ing specirlcdlly, but not exclusively, (i) coating only a portion of the first major surface 35 of each tape strip 30 with low adhesion bacL-.ci7e S0, (ii) coating only a portion of the second major surface 36 of each tape strip 30 withadhesive 40, and (ii) pattern coating the adhesive 40 onto the second major surface 36 of each tape strip 30 in a fashion similar to the pattern coatingS of the low30 adhesion bar~i7e 50 described above.
Adhesive Tape Flag Pad Individual Tape Flags As shown in Figure 10 through 13, the adhesive tape flag embo~liment of the invention comprises a leader strip 60 att~hed to a pad 120 of adhesive tape flags 130.
The adhesive tape flag pad 120 is comprised of a plurality of superimposed individual tape flags 130. The tape flags 130 are constructed from a flexible substrate 130s, such as paper, polyethylene, pol~..o~,~lene, polyethylene terephth~l~t~, etc.
The individual tape flags 130 define a lon~t~lrlin~l axis 130x and a lateral axis 130y and have a first longit~ inql end 131, a second lon~tu~lin~l end 132, a first lateral side 133, a second lateral side 134, a first major surface 135, and a second major surface 136.
The second major surface 136 of each tape flag 130 is coated with an adhesive 140, usually a reposition~ble adhesive. A first longitlldin~l end portion 138 of the second major surface 136 of each tape flag 130 is rendered tacky by the adhesive coating 140, while a second longitlldin~l end portion 139 ofthe second major surface 136 of each tape flag 130 is rendered n~ nt~ y by any suitable means such as application of a liner (not shown), applic~tion of det. ~~ifying particles (not shown), avoiding the initial application of adhesive 140 to the area, etc. This effectively divides the tape flag 130 into a tacky longiturlin~l end portion 138 and a nont~ck y lon~itudin~l end portion 139.
Tape Fla~ Pad The pad 120 of adhesive tape flags 130 defines a longitu-lin~l axis 120~ and a lateral axis 120y, and has a first lor~,eitudin~l edge 121 and a second lonE~iturlin~l edge 122. The pad 120 has an uppermost tape flag 130u and a lowermost tape flag 130p.The pad 120 is formed from any desired number of individual adhesive tape flags 130, pr~.ably between about lO and 120 tape flags 130, by adhering the second major surface 136 of each individual tape flag 130 to the first major surface 135 of an imme~ tely underlying tape flag 130. The tacky first lon~hldin~l end portion 68 ofthe leader strip 60 is adhesively bonded to the first major surface 35 of the uppermost tape strip 30u while the nontacky second lon~itudin~l end portion 69 defines a pull tab portion 69 which can be li~ed from the pad 20 and pulled to initiate d;spens,ng of the individual adhesive tape flags 130 from the pad 120 The individual adhesive tape flags 130 are then stacked in a Z pattern with succes~:~e flags 130 in the pad 120 positioned with the tacly area 138 of each flag 130 ~ ;ng between the first 121 and the second 122 longitu~ l edges of the pad 120. Such an alternating pattern causes the nont~y area 139 of each flag 130to be pulled from the surface of the pad 120 when an immediately overlving flag 130 is peeled from the pad 120.
For purposes of ~rilitatin~ further dicalss;on of the invention, the balance of the diccu~ion will be based upon the adhesive tape strip embodiment only. This is not intP.nded and should not be construed to limit the scope of the invention in any way.
Leader Strip A leader strip 60 having ~ll)sl~.lially the same width and about one halfto three quarters the length of the adhesive tape strip pad 20 is aligned with and sup. .;",posed over the first major surface 35 of the upperrnost tape strip 30u proxim~te the first longiturlin~l edge 21 ofthe pad 20.
The leader strip 60 defines a lon~it~ in~l axis 60x and a lateral axis 60y and has a first lon~iblAin~l end 61, a second longinlrlin~l end 62, a first lateral side 63, a second lateral side 64, a first major surface 65, and a second major surface 66. The second major surface 66 ofthe leader strip 60 is coated with an adhesive 40, such as a repositionahle adhesive or permanent pres;,.lre sensitive adhesive. A det~rL iryil~g coating 67 is positioned over the adhesive 40 along a first lon~inldin?l end portion 69 ofthe leader strip 60 so as to divide the leader strip 60 into a tacky first longinldin~
end portion 68 and a non~cL y second longit~ in~l end portion 69. The tacky first longitutlin~l end portion 68 of the leader strip 60 is adhesively bonded to the first major surface 35 ofthe uppermost tape strip 30u while the nont~c~y second lonpitlldin~l end portion 69 defines a pull tab portion 69 which can be li~ed from the pad 20 and pulled to initiate ~ ensiilg of the individual adhesive tape strips 30 from the pad 20.
CA 022~7262 1998-12-02 W 097/48560 PCT~US96/16733 The first longit~l-lin~l end 61 of the leader strip 60 iS aligned with the firstlongit~ in~l edge 21 of the pad 21 SO as to position the tacky first longitudin~l end portion 68 of the leader strip 60 pro,~ e the first longiturlin~l edge of the pad. The nont~y second lon~iturlin~l end portion 69 of the leader strip 60 iS pociti~n~d interme~ te the first 21 and second 221ongitll~{in~l edges ofthe pad 20 SO as to forrn a nont~c~y centrally positioned pull tab portion 69.
The pull tab portion 69 is preferably positioned on the pad 20 so that the free longit~ in~l end 62 of the pull tab portion 69 islongit~ in~lly spaced less than about one fifth of the lonEit~ldin~l length of the pad 20 away from the lateral axis 20y of the pad 20.
More specifically, the pull tab portion 69 is preferably positioned on the pad 20 such that a plane defined by the free longit~ in~l end 62 of the pull tab portion 69 and the lateral axis 20y of the pad 20 extends subst~nti~lly perpendicular to a plane defined by the uppermost tape strip 30u.
Alternatively, the pull tab portion 69 iS prere,.,bly positioned on the pad 20 such that a plane defined by the free longitu-lin~l end 62 of the pull tab portion 69 and the lateral axis 20y of the pad 20 extends subst~nti~lly perpçn~icul~r to a plane defined by the uppermost tape strip 30U.
A third alternative method of measuring the desired position of the pull tab portion 69 on the pad 2o longit~ in~lly positions the free loneit~l~lin~l end 62 of the pull tab portion 69 bel-. cen a first lon~ din~l boundary defined by the longitudin~l position of the lateral axis 20y of the pad 20, and a second longitlldin~l boundary eYten~ing a ~li.ct~nce of about one fifth of the lon~it l~lin~l length of the pad 20 from the lateral axis 20y and the pad 20 towards the first longit~ in~l edge 21 of the pad 20.
A fourth alternative method of measuring the desired position of the pull tab portion 69 on the pad 20 positions the free lor git~ in~l end 61 of the pull tab portion 69 prox;~ e the lateral center of the opening 74 in the dispenser 70.
Dispenser The adhesive tape strip pads 20 and adhesive tape flag pads 120 can be conveniently dispensed from any of the commonly used dispensers for such pads.

The center tabbed leader strip 60 provides the advantage of allowing the pad 20 to be partially inserted into the dispense. 70 with the pull tab portion 69 resting against th first abutment surface 75f while the operator presses down on the other end of the pad 20 and closes the ch~mhçr door (llnmlmhered).
The diepen~er 70 may be constructed as a shuttlin~ dispenser or a non.chllttling dispen~er. As shown in Figure 16, a ~hl~ttli~ dispenser 70 has a retentio~ cl~ er 76 with a length which perrnits the pad 20 within the cl-~,.,her 76 to shuttle back and forth within the ch~llber 76 as individual tape strips 30 are pulled from the pad 20. Alternatively, as shown in Figures 1 through 6 and 10, a non~h~lttli~ dispenser 70 has a retçntion chamber 76 which is sized to accommodate a pad 20 with subst~nti~lly no space for back and forth sh~-ttlin~ of the pad 20 within the ch~mher 76 as individual tape strips 30 are pulled from the pad 20.
Method of Making The center tabbed adhesive tape strip pads 20 of this invention, as well as center tabbed adhesive tape flags pads 120, may be quickly, easily and reliably m~nllf~r,tllred from large master pads 200 ofthe type commonly utilized to produce standard adhesive tape strip pads.
The center tabbed aspect of the invention may be conveniently added to a master pad 200 using lengths of tabbing material 210 which are confi~res with (i) first 213 and second 214 sides; (ii) a first major surface (not shown) having n~rlt~r.l~y first and second side margins 218 and an adhesively coated tacky central area 219 between the side Inal~ins, and (iii) a nontacky second major surface (not shown).
The procedure for applying the lengths oftabbing material 210 to a master pad 200 and cutting the re~ -lt~rlt tabbed master pad 200 to produce the desiredadhesive tape strip pads 20 incl~ldes the steps of (1) conveying a master pad 200 of superimposed adhesively coated sheets in a m~rhine direction 200m; (2) ~imlllt~neously con~/~ying continuous lengths of tabbing material 210 in the m~hine direction 200m, (3) l~ t;.~g the first major surface (not shown) of each length of tabbing material 210 to the exposed second major surface (unmlmhered) ofthe uppermost sheet ~llnmlmh~red) on the master pad 200, with the lengths oftabbing material 210 laterally positioned on the master pad 200 so as to create side margins 205 and int~. ..,e~ e gaps 206 bel~ n neighboring lengths of tabbing material 210 5 which are not covered with tabbing material 210; (4) cutting the tabbed master pad 200 in the ~-hine direction 200m along the central lo~itu~in~l axis 219~ ofthe tacky portion 219 ofthe tabbin~ m~teri~l 210 and along a line which is centrallypocitirJnçd within the int~-..e1;~te gaps 206 b~Lv~ n Iengths oftabbing material 210 so as to produce continl~ou~ ~hine direction lengths of tape; and (S) cutting the tabbed master pad in the transverse direction 200t so as to produce tape strip pads 20 of the desired width.
The lateral length of the side margins 205 on the master pad 200 which are not covered with tabbing material 210 are preferably about one third to one half the lateral length of the tacky central area 219 on the tabbing material 210 in order to 15 result in proper position;~ ofthe r~ y side Illargins 218 on the resultant adhesive tape strip pads 20 which include such side ,llarghls 205. For the same reason, the intel...e~ e gaps 206 between neighboring lengths oftabbing material210 on the master pad 200 which are not covered with tabbing material 210 are preferably about the same lateral length as the tacky central area 219 on the tabbing 20 material 210.
Method of Using Use of a disp~cer p~rl~age 10 co..lA;~ g the center tabbed adhesive tape strip pad 20 of the invention is illustrated in Figures 2 through 6. First, the cover 80 is removed from the dispen~er 70 (Figure 3). The eApGsed pull tab portion 69 is then gripped with the thumb and pointer finger and pulled through the opening 74 in the top 73 ofthe ~I;s~el~f~r 70 (Figure 4) until the leader strip 60 is pulled completely out of the retention ~ ...her 76 (Figure S). This causes a first lon~itu-lin~l end 31 of the ulJpc.lllosL adhesive tape strip 30u to be pulled through the opening 74 in the top 73 ofthe ~licp~n~el 70 ~igure 5) and rest against the second abutment surface 75b on the ~icp~n~Pr 70 once the leader strip 60 is fully det~ched (~igure 6).
Wl l ~l CENTER TABBED LEADER STRIP
Field of the Invention 5The invention broadly relates to pads of adhesive tape strips and adhesive tape fiags. More spe~ifi~ y, the invention relates to leader strips used to initiate dis~,~ ns;llg of individual adhesive tape strips and adhesive tape flags from such pads.
B~ckground 10Rolls of adhesive tape and pads of adhesive tape flags are widely used throughout the world. The most widely used variety of adhesive tape flags are those which utilize a reposition~le adhesive.
Rolls of reposition~ble tape, such as the "Post-It~)" brand rolls of reposition~' tape sold by Milulesota Mining and M~mlf~ctl~ring of Saint Paul, 15 M;~nPsola, have a variety of uses, incl~rlin~ the mountin~ of customized signage sheets to a window (e.g. "Dog Lost Poster") and ~ ulltlng easel pad pages to a wall after they have been removed from the easel pad.
Pads of repocitioDable tape flags, such as the widely used "Post-It~)" brand tape flags sold by M;..nesota Mining and M~mlf~ ring of Saint Paul, Minnesota 20 have become a staple office supply product throughout the world.
A variety of d;s~ se. ~ have been developed for the pads of adhes*e tape fiags. These ~ Je~ include (i) disposable and refillable dispensers, (ii) shuttlin~
and nol-.~h..~ 8 di~pe. s~, (iii) high volume/high profile and low volume/low profile dixpc~ s, (iv) single pad and ml~lfiple pad ~ic~C~ P ~, (v) hand held and mountable 25 dispensers, etc.
One co.---.-on feature found on most pads of adhesive tape flags, regardless of the type of ~ e- used, is the pre3e.,ce of some type of leader strip used to initiate pe~,c;i~ of individual flags from the pad. While a variety of useful leader strip confi~lrations have been developed, a con~ Jil~e need exists for a leader strip 30 confi~ation which is simple and ;l.~ -l e c;~e to m~nuf~ct~re and install, useful with a variety of diael~nl types of di~l,c ..~, ~, reliable, and easy for cQn~u~ to use.
CA 022~7262 1998-12-02 W 097/48560 PCTrUS96/16733 Summary of the Invention We have discovered a unique leader tape confi~ration for use in connection with pads of adhesive tape strips and adhesive tape flags.
5 Adhesive Tape Strip Pad The adhesive tape strip embodiment of our invention comprises a leader strip ~n~rhed to a pad of adhesive tape strips. The pad cor.ll,.;ses a plurality of superimposed individual tape strips.
The first major surface of each tape strips is coated with a low adhesion 10 baçl~ci7e to f~r.ilit~te separation ofthe individual strips, while the second major surface of each tape strip is coated with an adhesive. The pad in~ des an uppermost tape strips with an exposed first major surface of the uppermost tape strips, and a lowermost tape strips with an exposed second major surface of the lowermost tapestrip.
The leader strip is aligned with and superimposed over a position ofthe exposed first major surface of the uppermost tape strip. A tacky first longit~l~lin~l end portion of the leader strip is positioned prox;. . .~le the first lon~tl1din~l edge of the pad and adhesively bonded to the exposed first major surface of the uppermost tape strip, while a ncrt~cl~y second longit~lrlin~l end portion ofthe leader strip is 20 positioned intermPdi~te the first and second longitudin~l edges of the pad so as to form a nnnt~cL y centrally positioned pull tab portion.
The pull tab portion does not bond to the pad and can be readily grasped for initiating dispensing of individual tape strips from the pad. The pull tab portion is preferably positioned so that the free longitudin~l end of the pull tab portion is 25 longit~l~in~lly spaced less than about one fifth the complete longih~(lin~l length of the pad away from the lateral axis of the pad.
Contin.led dispensing of the individual tape strips is achieved by (i) adhering the second major surface of each individual tape strip in the pad to the first major surface of an imme~ tPly underlying tape strip at a first adhesive sl- en~lh, except for 30 a selected area plo,~;...~te one ofthe lon~it~l~lin~l edges ofthe strip where the tape strip is adhered to the first major surface of the ;~...--e~ lely underlying strip at a lower adhesive strength, and (ii) configllring the individual tape strips in the pad so W 097/48560 PCTrUS96/16733 that s~lcces~ive strips in the pad are positioned with the lower adhesive ~1l er,glll area of each strip all~ aling between the first and second longitlldinAl edges of the pad.
The diLrerence in adhesive strengths is s~leeted so that the lower adhesive sllellglh portion of each strip will d~ e from the ;~ ely underlying strip when an5 immedi~tely ov~,.ly;ng strip is peeled from the pad.
The change in adhesive sl,~nglh can be achieved by several meel~nic,".c inr~ 1ing (i) coating only a portion of the second surface of each tape strip with adhesive, (ii) pattern coating the adhesive onto the second surface of each tape strip so as to coat less adhesive onto a portion of the second surface of each tape strip, (iii) 10 pattern coating a low adhesion b~A.~l~ci7e onto the first surface of each tape strip so as to coat less b~A.~ I ~; e onto a portion of the first surface of each tape strips, etc.
Adhesive Tape Flag Pad The adhesive tape flag embodiment of our invention is sul.sl ~ Ally similar to 1 S the adhesive tape strip embodim~nt and comprises a leader strip ~tt~çhed to a pad of adhesive tape flags. The pad of flexible adhesive tape flags comprises a plurality of s.lpcl;~..posed individual tape flags which form a unitary pad having an uppellllost tape flag with an eAI.03ed first major s~lrfA~e, and a lowermost tape flag with an exposed second major surface. The first major surface of each tape flag has (i) a first 20 tacky area pro~ te a first longit.l-linAl end of the flag which is coated with a repositiQn~ble adhesive, and (ii) a second nont~y area proximAte a second lon~tu~in~l end of the sheet.
The leader strip is aligned with and supc,i-..l,osed over a portion ofthe exposed first major surface of the uppermost tape strip. A tacky first lonpitudinAI
25 end portion ofthe leader strip is positio~ed p-o,.;.~ e the first longitu~inAl edge of the pad and adhesively bonded to the exposed first major surface ofthe uppermosttape flag plox;... ~le the nont~c~y second longit~ldinAI end ofthe uppermost tape flag.
A nont~el~y second lonpit~ inAl end portion of the leader strip is positioned i-lle-.~.F,d;~te the first and second longit~ inAI edges ofthe pad so as to form a 30 nr)nt~cl~y centrally pos;l;oned pull tab portion.
The pull tab portion does not bond to the pad and can be readily grasped for initiAting dispensing of individual tape flags from the pad. The pull tab portion is CA 022s7262 1998-12-02 W 097/48560 PCTrUS96/16733 preferably positioned so that the free lon~it~lrlinAl end of the pull tab portion is longit~ldin~lly spaced less than about one fifth the colllplcte longjt~ in~l length of the pad away from the lateral axis of the pad.
Contin~led ~lisp~n.~;ng ofthe individual tape flags is achieved by (i) adhering the tacky first longit~ inql end ofthe second major surface of each individual tape flag in the pad to the first major surface of an immediAtely underlying tape flag, and (ii) confi~lring the individual tape flags in the pad so that successive flags in the pad are positioned with the first lon~ib~inal end of each flag alternating belween the first and second longitlldin~l edges of the pad.
Di;,~e ~cr The adhesive tape strips pads and adhesive tape flag pads can be conveniently dispensed from a dispenser comprising an enclosure dçfining a retention chamber into which the pad is inserted. The çnrlQs~lre has a base, side walls, and a top with a centrally positioned ope.ullg having a width which typically extends subs~ lly the entire width of the retention ch~.ber and a length which is large enough to permit the passage of a tape strip or flag through the opening yet small enough to prevent the full length of a tape strip or flag from falling back into the retention cl,~llbel once a portion of the tape strip has been pulled through the opening.
A cover may optionally be provided for purposes of sealing the opening through the top of the enclosure and exposing the leader strip when the cover isremoved.
The dispenser may be constructed as a single use dispenser to be discarded when the pad of tape strips or tape flags within the ret~ntion chamber are ~,Yh~llste~
or a rçfillAble di~ er e~luipped with a ~echA~ic~lop~l b'e for allowing accesses to the retention ch~llber for purposes of inserting a new pad into the chamber.
The dispenser may also be constructed as a .ehllttling or noneh~lttlin~
dispenser, with the length of the retention ch~lbe- either oversized to permit back and forth eh~ in~ of the pad within the chamber as individual tape strips or tape flags are pulled from the pad, or sized to accommoclate the pad with s~ A~ lly no space for back and forth ~h~ll llinp of the pad within the cl~ -ber as individual tape strips or tape flags are pulled from the pad.
W 097/48560 PCTrUS96/16733 Method of Making Adhesive Tape Strips and Flags The invention in~ dç$ a method of making the centrally tabbed adhesive tape 5 strips and adhesive tape flags (here;n~l~r l.,fe~ ced collectively as "adhesive tape") comprising the steps of:
(1) CO~ lg a master pad co~ ni..g a plurality of sul~.i"lposed adhesively coated sheets in a machine direction, with each sheet having (i) a tacky first major surface; (ii) a nontacly second major surface, and (iii) first and second sides;(2) cGIl~c;ying a continllollc length oftabbing material in the m~hine direction, with the tabbing material having (i) first and second sides; (ii) a first major surface having r ~ntaCL y side "la~gh~s and a tacky central area between the side I~lUgillS coated with an adhesive, and (iii) a nol~t~cl~y second major surface;
(3) I~...;n~til~ the first major surface of a length of the tabbing material to the 15 second major surface of the ul~pe~ ost sheet on the master pad, with the tabbing materi~l offset from both sides ofthe master pad so as to define uncovered side algllls on the master pad;
(4) cutting the tabbed master pad in the m~rhin~ direction within the tacky portion ofthe tabbing material so as to produce contin~o~c ...~.hi~e direction lengths 20 of tape having (i) a first side portion covered with the adhesive portion of the tabbing material, (ii) a second side portion free from tabbing material, and (iii) a nontac~y tab ...e~;~le the first and second sides of the tape formed from one of the nont~
side l"&~ins on the tabbing material; and (5) cutting the tabbed master pad in the ll~ c direction so as to produce 25 tape of a desired width.
When two or more lengths oftabbing Illaltl;al are l~min~ted to the master pad ofthe adhesive sheets, the m~m~f~ct~ring process must comply with two ad~ition~lte4ui~",t"1s. First, the lengths oftabbing m~tÇ~l must be offset from each other so as to define interrnedi~te gaps b~l~een the lengths of tabbing material 30 on the master pad which are not covered with tabbing material. Second, the tabbed master pad must be cut in the maçhine direction bet~n~,en adjac~t pairs of nontacky side Illargins from dilre ~, nt Iengths of tabbing m~te~

The term "repositionrt'E adhesive" is a tenn of art which is utilized herein in accoldance with its standard indust~ m~ning Broadly, a repositic-n~hle adhesive is an adhesive which permits typical tape strip and tape flag substrates, such as paper and polymeric films, to be repe~tedly ~tt~ched to and removed from various s~rf~ces, 25 such as paper, without ~igrific?nt loss in adhesive strength, without leaving adhesive residue upon the surface, and without destruction of the s~s~la~e.
The terrn "tape flag" is a widely used term of art which is utilized herein in accordance with its standard industry m~ni~ Broadly, a tape flag is a flexible substrate with a first end of a first major surface coated with an adhesive, usually a 30 reposition~ble adhesive, and a nont~c~y second end of the first major surface. Tape flags are usually rect~ng~ r in shape and about 1 to 6 cm wide and about 3 to 10 cm long although other sizes and shapes are certainly possible. The nontacky end of the CA 022~7262 1998-12-02 W O 97/48560 PCTrUS96/16733 substrate is typically color coded or printed with indicia. A variety of means can be employed to render the second end ofthe first major surface nsnt~~~y inclll~ing (i) limiting application of the adhesive coating to only the first end of the first major surface, or (ii) allowing the adhesive coating to be applied to the entire surface area 5 of the first major surface and then applying a nontacky material, coating or liner over the adhesive at the second end.
The term "tape strip" is a widely used term of art which is utilized herein in accoldance with its standard industry me?nine Broadly, a tape strip is a flexible substrate with a first major surface coated with an adhesive. Tape strips are usually rect~n~ r in shape and about 1 to 10 cm wide and about 3 to 20 cm long, most frequently about 1 to S cm wide and about 3 to 10 cm long, although other sizes and shapes are certainly possible.
Construction A unique leader strip 60 is provided for use on adhesive tape strips pads 20 and adhesive tape flag pads 120. The leader strip 60 is simple and inexpensive to m~mlf~ctllre and install on the pads, useful with a variety of di~~ types of dispensers, reliable, and easy for con.~l~mers to use.
Adhesive Tape Strip Pad Individual Tape Strips As shown in Figures 1 through 9, the adhesive tape strip embo~liment of the invention comprise a leader strip 60 att~rhed to a pad 20 of adhesive tape strips 30.
The adhesive tape strip pad 20 is comprised of a plurality of superimposed individual tape strips 30. The tape strips 30 are constructed from a flexible substrate 30s, such as paper, polyethylene, poly~.ol.ylene, polyethylene terephth~l~te, etc. The individual tape strips 30 define a longit~din~l axis 30x and a lateral axis 30y and have a first longitudin~l end 31, a second lon it ldin~l end 32, a first lateral side 33, a second lateral side 34, a first major surface 35, and a second major surface 36. The first major surface 35 of each tape strip 30 is coated with a low adhesion bac~i7e 50 to farilit~te separation of the superimposed individual strips 30. The second major W O 97/48560 PCT~US96/16733 surface 36 of each tape strip 30 is coated with an adhesive 40, such as a reposition~hle adhesive or a pe.lllane.ll pressure sensitive adhesive.
Tape Strip Pad The pad 20 of adhesive tape strips 30 defines a loneih1~in~1 axis 20x and a 5 lateral axis 20y, and has a first longjt~ in~l edge 21 and a second longitu~inAl edge 22. The pad 20 has an uppemmost tape strip 30u and a lowermost tape strip 30p.
The pad 20 is fomled from any desired number of individual adhesive tape strips 30, p-~,f~l. bly b~ .een about 10 and 120 tape strips 30, by adhering the second major surface 36 of each individual tape strip 30 to the first major surface 35 of immPdi~tPly underlying tape strip 30. The first major surface 35 of the tape strips 30 are pattem coated with a low adhesion ba~ e 50 with a first pattern coating provided over a first area 51 and a second pattern coating provided over a second area 52 of the adhesive tape strips 30. The first pattem coating permits a higher ~lhesi~n stlellgll- than the second pattern coating (i.e., the pattern ofthe first pattem 1 S coating covers less surface area than the pattern of the second pattern coating). The individual adhesive tape strips 30 are then stacked in a Z pattern with succes~;ve strips 30 in the pad 20 positioned with the high ~ Psion pattern coated area 51 of each strip 30 allelllalillg be~ the first 21 and the second 22 longjtudtn~l edges of the pad 20. The di~el e"ce in adhesive strength between the high adhesion pattem20 coated area 51 and the low adhesion pattern coated area 52 is selected so that the lower adhesive sh~n2~ portion 52 of each strip 30 will~el~min~te from the ;....ne.l;~lçly unde~ g strip 30 when an ;,,,,,,ç~ Ply overlying strip 30 is peeled from the pad 20.
The change in adhesive ~ ,nglh can also be aç~;Avcd by several other 25 ,n~chAn..c.n.c, inclu~ing specirlcdlly, but not exclusively, (i) coating only a portion of the first major surface 35 of each tape strip 30 with low adhesion bacL-.ci7e S0, (ii) coating only a portion of the second major surface 36 of each tape strip 30 withadhesive 40, and (ii) pattern coating the adhesive 40 onto the second major surface 36 of each tape strip 30 in a fashion similar to the pattern coatingS of the low30 adhesion bar~i7e 50 described above.
Adhesive Tape Flag Pad Individual Tape Flags As shown in Figure 10 through 13, the adhesive tape flag embo~liment of the invention comprises a leader strip 60 att~hed to a pad 120 of adhesive tape flags 130.
The adhesive tape flag pad 120 is comprised of a plurality of superimposed individual tape flags 130. The tape flags 130 are constructed from a flexible substrate 130s, such as paper, polyethylene, pol~..o~,~lene, polyethylene terephth~l~t~, etc.
The individual tape flags 130 define a lon~t~lrlin~l axis 130x and a lateral axis 130y and have a first longit~ inql end 131, a second lon~tu~lin~l end 132, a first lateral side 133, a second lateral side 134, a first major surface 135, and a second major surface 136.
The second major surface 136 of each tape flag 130 is coated with an adhesive 140, usually a reposition~ble adhesive. A first longitlldin~l end portion 138 of the second major surface 136 of each tape flag 130 is rendered tacky by the adhesive coating 140, while a second longitlldin~l end portion 139 ofthe second major surface 136 of each tape flag 130 is rendered n~ nt~ y by any suitable means such as application of a liner (not shown), applic~tion of det. ~~ifying particles (not shown), avoiding the initial application of adhesive 140 to the area, etc. This effectively divides the tape flag 130 into a tacky longiturlin~l end portion 138 and a nont~ck y lon~itudin~l end portion 139.
Tape Fla~ Pad The pad 120 of adhesive tape flags 130 defines a longitu-lin~l axis 120~ and a lateral axis 120y, and has a first lor~,eitudin~l edge 121 and a second lonE~iturlin~l edge 122. The pad 120 has an uppermost tape flag 130u and a lowermost tape flag 130p.The pad 120 is formed from any desired number of individual adhesive tape flags 130, pr~.ably between about lO and 120 tape flags 130, by adhering the second major surface 136 of each individual tape flag 130 to the first major surface 135 of an imme~ tely underlying tape flag 130. The tacky first lon~hldin~l end portion 68 ofthe leader strip 60 is adhesively bonded to the first major surface 35 of the uppermost tape strip 30u while the nontacky second lon~itudin~l end portion 69 defines a pull tab portion 69 which can be li~ed from the pad 20 and pulled to initiate d;spens,ng of the individual adhesive tape flags 130 from the pad 120 The individual adhesive tape flags 130 are then stacked in a Z pattern with succes~:~e flags 130 in the pad 120 positioned with the tacly area 138 of each flag 130 ~ ;ng between the first 121 and the second 122 longitu~ l edges of the pad 120. Such an alternating pattern causes the nont~y area 139 of each flag 130to be pulled from the surface of the pad 120 when an immediately overlving flag 130 is peeled from the pad 120.
For purposes of ~rilitatin~ further dicalss;on of the invention, the balance of the diccu~ion will be based upon the adhesive tape strip embodiment only. This is not intP.nded and should not be construed to limit the scope of the invention in any way.
Leader Strip A leader strip 60 having ~ll)sl~.lially the same width and about one halfto three quarters the length of the adhesive tape strip pad 20 is aligned with and sup. .;",posed over the first major surface 35 of the upperrnost tape strip 30u proxim~te the first longiturlin~l edge 21 ofthe pad 20.
The leader strip 60 defines a lon~it~ in~l axis 60x and a lateral axis 60y and has a first lon~iblAin~l end 61, a second longinlrlin~l end 62, a first lateral side 63, a second lateral side 64, a first major surface 65, and a second major surface 66. The second major surface 66 ofthe leader strip 60 is coated with an adhesive 40, such as a repositionahle adhesive or permanent pres;,.lre sensitive adhesive. A det~rL iryil~g coating 67 is positioned over the adhesive 40 along a first lon~inldin?l end portion 69 ofthe leader strip 60 so as to divide the leader strip 60 into a tacky first longinldin~
end portion 68 and a non~cL y second longit~ in~l end portion 69. The tacky first longitutlin~l end portion 68 of the leader strip 60 is adhesively bonded to the first major surface 35 ofthe uppermost tape strip 30u while the nont~c~y second lonpitlldin~l end portion 69 defines a pull tab portion 69 which can be li~ed from the pad 20 and pulled to initiate ~ ensiilg of the individual adhesive tape strips 30 from the pad 20.
CA 022~7262 1998-12-02 W 097/48560 PCT~US96/16733 The first longit~l-lin~l end 61 of the leader strip 60 iS aligned with the firstlongit~ in~l edge 21 of the pad 21 SO as to position the tacky first longitudin~l end portion 68 of the leader strip 60 pro,~ e the first longiturlin~l edge of the pad. The nont~y second lon~iturlin~l end portion 69 of the leader strip 60 iS pociti~n~d interme~ te the first 21 and second 221ongitll~{in~l edges ofthe pad 20 SO as to forrn a nont~c~y centrally positioned pull tab portion 69.
The pull tab portion 69 is preferably positioned on the pad 20 so that the free longit~ in~l end 62 of the pull tab portion 69 islongit~ in~lly spaced less than about one fifth of the lonEit~ldin~l length of the pad 20 away from the lateral axis 20y of the pad 20.
More specifically, the pull tab portion 69 is preferably positioned on the pad 20 such that a plane defined by the free longit~ in~l end 62 of the pull tab portion 69 and the lateral axis 20y of the pad 20 extends subst~nti~lly perpendicular to a plane defined by the uppermost tape strip 30u.
Alternatively, the pull tab portion 69 iS prere,.,bly positioned on the pad 20 such that a plane defined by the free longitu-lin~l end 62 of the pull tab portion 69 and the lateral axis 20y of the pad 20 extends subst~nti~lly perpçn~icul~r to a plane defined by the uppermost tape strip 30U.
A third alternative method of measuring the desired position of the pull tab portion 69 on the pad 2o longit~ in~lly positions the free loneit~l~lin~l end 62 of the pull tab portion 69 bel-. cen a first lon~ din~l boundary defined by the longitudin~l position of the lateral axis 20y of the pad 20, and a second longitlldin~l boundary eYten~ing a ~li.ct~nce of about one fifth of the lon~it l~lin~l length of the pad 20 from the lateral axis 20y and the pad 20 towards the first longit~ in~l edge 21 of the pad 20.
A fourth alternative method of measuring the desired position of the pull tab portion 69 on the pad 20 positions the free lor git~ in~l end 61 of the pull tab portion 69 prox;~ e the lateral center of the opening 74 in the dispenser 70.
Dispenser The adhesive tape strip pads 20 and adhesive tape flag pads 120 can be conveniently dispensed from any of the commonly used dispensers for such pads.
CA 022s7262 1998-12-02 W 097148560 PCTrUS96/16733 rY~ .?1~ ~r J.cpen~ 70 are shown in Figures 1 through 6 (first embodiment) and Figure 10 (second emborliment) The dispensers 70 have a base 71, a front wall 72f, a back wall 72b, side walls 72, and a top 73 split b~ n a first side 73f and asecond side 73b by a centrally pos;l;ol~ed opening 74 which extends s~lb~ y the 5 entire width ofthe retention cllA nt~er 76 defined by the d~ cr 70 The length of the opening 74 is large enough to permit the passage of a tape st~ip 30 through the opening 74 yet small enough to prevent the full length of a tape strip 30 from falling back into the retention chd,ll~er 76 once a portion of the tape strip 30 has been pulled through the opening 74 As shown best in Figures 4 through 6, removal of a tape 10 strip 30 from the d;~l,r~-sGr 70 causes an end portion (unm~. b~.~d) ofthe ; ....e~ tPly underlying a tape strip 30 to be pulled through the opening 74 and rest upon one of the ~butm~-nt surfaces 74r and 74s where it is plese.~led for futureremoval from the ~ c~ 70 A cover 80 seals the opening 74 through the top 73 of the di;,~e.-ser 70 The center tabbed pads 20 of this invention are particularly useful in col-ne-;lion with open throat dispe.lsc.~, such as shown in Figures 1 through 6 and 10, in which the openillg 74 in the top 73 of the di~r~n~pr 70 is of s~ffic;ent size, generally about one third to three fourths the length of the pad retained within the dispenser 70, to permit a user to read through the ope. hlg 74 and into the retention ch~ll~el 76 to access the pull tab portion 69 on the leader strip 60 Alte",alively, ~Itho~lgh less ple~,lc;d, the pull tab portion 69 on the leader strip 60 may be attached to the cover 80 so that the leader strip 60 is pulled from the d;spen~e~ 70, along with a portion of the UppcllllOSt adhesive tape strip 30u, when the cover 80 is relllo~ed from the ~t:~l,e ~er 70 Use of such an alternative embodiment is neceC~ ~ when the opening 74 in the top 73 of the ~icpPn~r 70 is less than about 2 cm since a usercannot reach into the retPntion cl~ ~ h~r 76 to access the pull tab portion 69 Due to the necessity of a larger opening 74 in non~hl-ttling di~. tns~, ~ 70, the pad 20 should be adhered to the base 71 of the dispenser 70 in order to prevent the pad 20 from being pulled through the opening 74 when individual strips 30 are pulled from the pad The dispenser 70 may be constructed as a single use dis~enser to be discarded when the pad 20 of tape strips 30 or pad 120 of tape flags 130 within the retention CA 022~7262 1998-12-02 W O 97/48560 PCT~US96/16733 chalnbe 76 are eYh~l-sted, or a refillable dispenser, such as shown in ph~ntom on Figure 16, equipped with a mech~ni~nl operable for allowing acce~ses to the retention chamber 76 for purposes of inserting a new pad 20, 120 into the chamber 76. The center tabbed leader strip 60 provides the advantage of allowing the pad 20 to be partially inserted into the dispense. 70 with the pull tab portion 69 resting against th first abutment surface 75f while the operator presses down on the other end of the pad 20 and closes the ch~mhçr door (llnmlmhered).
The diepen~er 70 may be constructed as a shuttlin~ dispenser or a non.chllttling dispen~er. As shown in Figure 16, a ~hl~ttli~ dispenser 70 has a retentio~ cl~ er 76 with a length which perrnits the pad 20 within the cl-~,.,her 76 to shuttle back and forth within the ch~llber 76 as individual tape strips 30 are pulled from the pad 20. Alternatively, as shown in Figures 1 through 6 and 10, a non~h~lttli~ dispenser 70 has a retçntion chamber 76 which is sized to accommodate a pad 20 with subst~nti~lly no space for back and forth sh~-ttlin~ of the pad 20 within the ch~mher 76 as individual tape strips 30 are pulled from the pad 20.
Method of Making The center tabbed adhesive tape strip pads 20 of this invention, as well as center tabbed adhesive tape flags pads 120, may be quickly, easily and reliably m~nllf~r,tllred from large master pads 200 ofthe type commonly utilized to produce standard adhesive tape strip pads.
The center tabbed aspect of the invention may be conveniently added to a master pad 200 using lengths of tabbing material 210 which are confi~res with (i) first 213 and second 214 sides; (ii) a first major surface (not shown) having n~rlt~r.l~y first and second side margins 218 and an adhesively coated tacky central area 219 between the side Inal~ins, and (iii) a nontacky second major surface (not shown).
The procedure for applying the lengths oftabbing material 210 to a master pad 200 and cutting the re~ -lt~rlt tabbed master pad 200 to produce the desiredadhesive tape strip pads 20 incl~ldes the steps of (1) conveying a master pad 200 of superimposed adhesively coated sheets in a m~rhine direction 200m; (2) ~imlllt~neously con~/~ying continuous lengths of tabbing material 210 in the m~hine direction 200m, (3) l~ t;.~g the first major surface (not shown) of each length of tabbing material 210 to the exposed second major surface (unmlmhered) ofthe uppermost sheet ~llnmlmh~red) on the master pad 200, with the lengths oftabbing material 210 laterally positioned on the master pad 200 so as to create side margins 205 and int~. ..,e~ e gaps 206 bel~ n neighboring lengths of tabbing material 210 5 which are not covered with tabbing material 210; (4) cutting the tabbed master pad 200 in the ~-hine direction 200m along the central lo~itu~in~l axis 219~ ofthe tacky portion 219 ofthe tabbin~ m~teri~l 210 and along a line which is centrallypocitirJnçd within the int~-..e1;~te gaps 206 b~Lv~ n Iengths oftabbing material 210 so as to produce continl~ou~ ~hine direction lengths of tape; and (S) cutting the tabbed master pad in the transverse direction 200t so as to produce tape strip pads 20 of the desired width.
The lateral length of the side margins 205 on the master pad 200 which are not covered with tabbing material 210 are preferably about one third to one half the lateral length of the tacky central area 219 on the tabbing material 210 in order to 15 result in proper position;~ ofthe r~ y side Illargins 218 on the resultant adhesive tape strip pads 20 which include such side ,llarghls 205. For the same reason, the intel...e~ e gaps 206 between neighboring lengths oftabbing material210 on the master pad 200 which are not covered with tabbing material 210 are preferably about the same lateral length as the tacky central area 219 on the tabbing 20 material 210.
Method of Using Use of a disp~cer p~rl~age 10 co..lA;~ g the center tabbed adhesive tape strip pad 20 of the invention is illustrated in Figures 2 through 6. First, the cover 80 is removed from the dispen~er 70 (Figure 3). The eApGsed pull tab portion 69 is then gripped with the thumb and pointer finger and pulled through the opening 74 in the top 73 ofthe ~I;s~el~f~r 70 (Figure 4) until the leader strip 60 is pulled completely out of the retention ~ ...her 76 (Figure S). This causes a first lon~itu-lin~l end 31 of the ulJpc.lllosL adhesive tape strip 30u to be pulled through the opening 74 in the top 73 ofthe ~licp~n~el 70 ~igure 5) and rest against the second abutment surface 75b on the ~icp~n~Pr 70 once the leader strip 60 is fully det~ched (~igure 6).
