J., a corporation of New York Original application April 8, 1950, Serial No. 154,808. Divided and this application April 29, 1950, Serial No. 159,008. r

1. This invention relates to an improved holder for rolls of tape such as masking tape and other re-usable tapes.

This application is a..continuation-in-part of my U. S. application Serial No. 154,808 for a Holder for a Roll of Tape, filed April 8, 1950.

Masking tapes and other re-usable tapes are commonly wound in cylindrical form on a hollow cardboard center core. The tape is frequently sensitive to pressure thereon and deteriorates from such pressure. This raises difliculties in the shipment and handling thereof.

In order to meet these d'ficulties, it is preferable to pack each roll of tape in its carton in such a manner that the longitudinal side wall of the roll is prevented from abutting the side walls of the'carton. It is possible to design a special carton with flaps which cooperate with the core of the roll of tape' and prevent it from touching't-he side walls of the carton. However,

such a construction is not satisfactory when it is desired to pack a plurality of rolls of tape in one carton, and furtherm'ore the roll of tape is subject to undue handling when it is removed from the carton.

My above-mentioned U. S. application Serial No. 154,808 discloses'an individual holder insert for each roll of tape. The invention disclosed in the 'mstant application relates to a holder insert of modified construction which is particularly suitable for use with'rolls of tape of athickness of two inches or more, which are the heavier commercial types of re-usable tape rolls.

The improved holder comprises a base mem-'- ber with a pair of complementary opposed integral flaps; These flaps are substantially rectangular and may be respectively bent under tension at right angles to the base. "An insert with a square cross-section is also provided. It may be brought into abutment with the base with the outer surfaces of the flaps bearing outwardly againstrespective opposite walls of said insert. Also, the side edges of the flaps respectively abut the other two walls of the insert.

One of the end faces of the roll of tape may be placed in abutment with the base member, with said insert extending through the core opening of said roll. The longitudinal corner edges of the insert respectively abut the longitudinal side wall of said core opening and permit the roll to turn with respect to the holder. However; the construction is such that lateral movement of the roll with respect to the holder is strongly resisted.

If a still strongerconstruction is.;desi17ed,.;a

3 Claims. (Cl. 206--52) 2 second holder may be face of the tape roll, with the flaps of this second holder preferably oriented at right angles to the flaps of the first holder.

height of the insert may be made slightly greater than the thickness of the roll; and as a result the roll may be turned with almost no pressure being exerted on its end faces.

Other objects and advantages of this invention will be apparent from the following description and the annexed drawings, in which preferred embodiments are disclosed.

In the drawings:

Fig. l is a plan view showing a roll of tape mounted on a holder insert;

Fig. 2 is a section on line 2--2 of Fig. 1;

Fig. 3 is a vertical section showing a roll of tape mounted on upper and lower holders and packed in a carton; and

Fig. 4 is a section on line 4-4 of Fig. 3.

Upon reference to the drawings in detail, and in particular to Figs. 1 and 2, it will be seen that the improved holder comprises a base In with integral flaps H which are interfitted :with insert 20. Tape roll I2 is in turn interfitted with this insert 20. a This tape roll I2 is conventional and comprises tape of any suitable type, which is Wound in layers around center core [4. This core I4 is generally made of cardboard or other material and is cylindrical in shape with open ends. Tape roll I2 is also cylindrical in shape with substantially parallel and planar end faces.

The invention is particularly useful when tape roll 12 is a masking tape or other type of tape which is sensitive to pressure thereon. This is because the holder tends to prevent the longitudinal side wall of roll [2 from coming into contact with the wall of any container in which said roll ['2 might be placed.

Base in and flaps I! are preferably punched from a single blank, with flaps ll integral with base member l0. Insert 20 is preferably punched from a second blank and suitably scored so that it may be folded and secured in its final shape. These blanks may be made of a suitable material which is relatively inexpensive, and which is stiff but permits sufiicient articulation of flaps H and insert 20. Such a material may be one of a'number of types of paper board-including kraft board, fibre board, corrugated board and cardboard. Vulcanized fibremay also be used. However, the invention is not limited to these materials.

'. The blanks may be unfinished, but the blank mounted on the other end I Optionally, the

material non-adherent to the surface of base II]...

If rolls of tape, as mounted on these holders, are to be stacked, both surfaces ofbase I 0 will abut end face of a tape roll [2; and therefore both faces of base I0 should be treatedinthe above manner.

One important advantage of this treatment of the blank with wax is that it permits free turnability of roll 12 with respect. to base Ill.

Base It may be of any desired sizeand' shape; so long as roll l2 nowhere protrudes over the edge of said base when mounted thereon. Base in may be square with rounded corners, as clearly shown in Fig. l, 01' round as clearly shown in Fig. 4. However, the-invention is not limited to these shapes of base [0.

Flaps l I oppose each other andare respectively cut out from base l0 and are connected thereto by means of respective hinge lines 13. These hinge lines H are preferably parallel and equidistant from the center of base It. Each flap H is preferably substantially rectangular in shape, save that its detached corners may optionally be rounded. Each flap II has detached peripheral side edges l8 and. a detached peripheral connecting edge ll.

Hinge lines l3 are so formed that flaps I] tend to return to the plane of base if! when their respective detached edges I! are held away from said plane. When flaps H are respectively bent 90 from the plane of base in, until said flaps II are substantially parallel, the exert a considerable force in opposite directions.

When flaps l! are thus bent until they are parallel, they are adapted to be inserted in insert 26; lC'his insert 29 comprises four substantially rectangular wall panels 2! and a glue flap 22. These walls 2! are joined at three corner edges by respective scored hinge lines 23. Glue flap 22 is hingedly connected to one of the'walls 2i; at the fourth corner edge by means of, a fourth scored hinge line 23. Glue flap 22 is glued or secured by other suitable means to the insideof the other wall 23 which is adjacent to saidv fourth corner edge.

As a result of this construction, insert 20 may be folded until it is substantially flat, and it may also be folded into a position in which it is substantially square in. cross-section. When insert 20 is in this latter position, it may be interfitted with base H3 and flaps H, with the base edges of walls 2! in abutment with said base. 10 and said flaps ll respectively bearing against respective opposed walls 2|. In this interfitting position, the side edges i8 of flaps ll respectively approximately abut the walls 2i adjacent to the walls 2| against which these flaps Iibear.

After the holder has been thus formed by the assembly of base it] and flaps H with insert 20, the holder may be assembled with tape roll 12, with one end face of roll l2 adjacent base H3 and with insert 28 inserted within core l4. Thefour corner edges of insert 26 respectively approximately abut the inner wall of core l4. Core I4. is sufficiently loosely held by insert 20 so as to be turnable with respect thereto, but lateral movement of roll 12 is limited.

The above construction resists transverse force on the longitudinal side wall of roll l2. Any force on one of the two walls 2! against which a respective flap ll bears is resisted by the outward force exerted by that flap ll. Any force on either. of the. other two. wallsll. is strongly resisted, because that wall 2 l bears: against respective side edges [8 of the flaps ll.

This holder may be constructed for use with tape rolls I2 of varying dimensions. Thus the diameter oflthe. inner wall of core It may be of any value d. In that case, each wall 2| is of a width approximately: vii. Making allowance for. the thicknesssof score lines 13 and of walls,

21-, the length .of. each score line I3 is also approximately /za/fi and the distance between saidxscore lines. i3. is approximately /2 d.

The height of insert 20 may be any desired fraction of the height or thickness of core l4.

In Fig. 2, holder 2| is shown as having the same height as core 14. This facilitates stacking of a plurality of tape rolls l2, each mounted on holders. Optionally, the height of insert 20 ma be less than that of core M.

The distance betweenhinge line i3 and edge 18. of each flap ll may be any desired'fraction of the height of insert 20, this distance being shown in the drawings as one-half said height of insert 20.

It has: been found good practice for certain tape .rolls to. apply holders to each end face thereof. This is. shown in. Figs. 3 and 4, in which identical holders are shown respectively applied to the upper and lowerend faces of tape roll I2; These holders utilize a common insert 2011. which is. entirely similar to insert 20, save that the walls 21a; of this insert 20a are higher than core l4.

As in the construction of Figs. 1 and 2, a base member. Ill is applied against one end face of roll l2,. with flaps ll extending inside insert 20a and respectively bearing. against one pair of opposed walls am.

A. second base member H! is similarly applied to the other end face of roll l2 and is turned with respect to the. first base I0, so that the second'pair of flaps l l respectively abut the other pairof opposedwalls 2la.

As a resultof this construction, force against any of the walls Zia is resisted as a result of the said wall 2la bearing against side edges ill of a respective pair of flaps II, as well as by the resistance of a flap. ll'bearing against this wall. 2m... The holder. protects even very heavy rolls of tape against transverse movement into abutment withthe walls of any container in which they might be placed.

Furthermore, roll l2 may be readily turned Without removing it from its holder. Any necessary holding force on; respective members 10 of the assembly may be exerted .on the areas of these members I0 within: walls 21a. As a result almost no force is exerted on the end faces of roll 12, thereby. further protecting it from damage;

Tape roll l2, together with either one or two holdersinounted on its respective end faces, may be packed in individual cartons. This is shown in Figs. 3 and 4, in which roll I2 is packed in carton f9. Basel), flaps ll and. insert 290. hold rol1.1|2. spaced from the side walls of said carton .l 9.

When this methodv of packing is-used, roll 12 may optionally be unrolled without being removed from carton 19; Figs. 3 and 4 show one scribed above, core I4 is then turnable on insert 20a. Vertical movement of the holder is limited y he pper and lower walls of carton i9, and undue pressure on the end faces of roll i2 may be prevented by handling these upper and lower walls of carton [9 within the area thereof bounded by walls 210..

Optionally, as shown in Figs. 3 and 4, base l0 may be round, and this is advantageous if for some reason roll !2 does not turn freely with respect to insert No. In that case, base It also turns, and roll l2 unrolls freely. Base iii may also be of suitable polygonal or other shape so that it turns freely in carton i9.

Optionally, a plurality of tape rolls l2, each mounted on a single holder or on two holders, may be packed in a single carton.

Preferred embodiments of the invention, as well as various changes, omissions, substitutions and variations which can be made therein, have been disclosed. Numerous other changes, omissions, substitutions and variations can be made Without departing from the scope and spirit of the invention.

The improved holder may be used with rolls of tape, including pressure-sensitive tape, and with other types of rolls, such as rolls of ribbon. Any roll can be used, so long as it has an end wall and an opening communicating with that end wall, said opening having a cylindrical sidewall.

Optionally, the distance between hinge lines I3 may be less than /2d, and flaps I! may bear against respective walls 2! at an angle.

In the construction of Figs. 3 and 4, the distance between flap edges I! and i8 may optionally be greater than one-half the height of wall 2la. As an example, this may be possible if the width of each flap II is slightly less than the 'inside width of wall 2 la.
