Fields, La Grange, 11]., assignor to Continental Can Company, Inc., New York, N.Y., a corporation of New York Filed Jan. 22, 1965, Ser. No. 427,450 8 Claims. (Cl. 215-11) This invention relates to a novel container and in particular to a novel disposable infant-nursing bottle or pouch, and to a novel method of forming the pouch and a nipple thereof from a single web of flexible material.

An object of this invention is to provide a novel pouch particularly adapted for dispensing a liquid product pack aged therein to an infant, the pouch being characterized by being constructed from a sheet of material folded to define a body having aligned upper edge portions opposite a folded bottom portion and sealed adjacent side edge portions between the upper and bottom portions, and an integral nipple cold-formed or hot drawn from the sheet material and projecting outwardly of the body through which liquid packaged in the pouch is dispensed.

A further object of this invention is to provide a novel pouch of the type described and including a covering substantially encasing the pouch body, the covering being secured to the pouch body and having at least one portion free of the pouch body for manually severing the covering to gain access to the pouch without rupturing the pouch body, and the free portion of the covering including a notch for facilitating the manual severance and removal of the covering prior to the initiation of a dispensing operation.

Still another object of this invention is to provide a novel pouch of the type described in which the nipple is disposed closely adjacent the folded bottom portion of the pouch body and indicia is provided adjacent the up per aligned edge portions for indicating the quantity of liquid remaining in the pouch during a dispensing operation by inverting the pouch to position the nipple in an uppermost position.

A further object of this invention is to provide a novel method of forming a pouch of the type described by feeding a web of flexible material along a predetermined path, cold-forming or hot drawing a generally conical nipple in a portion of the web, folding theweb longitudinally to bring opposite longitudinal edge portions thereof into aligned relationship opposite a folded portion, and heat sealing the Web at each side of the nipple between the folded portion and the aligned edge port-ions whereby the pouch has an opening opposite the folded portion by means of which the pouch is charged with a dispensable product.

A further object of this invention is to provide a novel method of forming a dispensing pouch adapted to be charged with a dispensable product including the steps of feeding a first web of flexible material along a predetermined path, forming a generally conical nipple in a portion of the web, folding the web to bring opposite longitudinal edge portions thereof into aligned relationship opposite a folded portion of the web, heat sealing the web at each side of the nipple between the folded portion and the aligned edge portions thereby forming a pouch opened opposite the folded portion and sealed along sides adjacent thereto, applying second and third covering webs to opposite faces of the pouch and joining the covering webs to the pouch at least along the sealed sides thereof.

Still another object of this invention is to provide a novel method of forming a pouch including each of the steps immediately above described, and in addition, notching the covering Webs adjacent the folded portion of the pouch to provide means for facilitating the removal of the covering webs upon the complete assembly and charging of the pouch.

With the above, and other objects in view that will hereinafter appear the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims and the several views illustrated in the accompanying drawings:

In the drawings:

FIGURE 1 is a schematic side elevational view of an apparatus for forming pouches in accordance with this invention, and particularly illustrates the formation of a plurality of nipples in a first web of flexible material, the formation of this web into a plurality of pouch portions, the application of second and third covering webs to opposite faces of the pouch portions and the subsequent charging, sealing and severing of the three Webs.

FIGURE 2 is a schematic top plan View of the apparatus of FIGURE l, and more clearly illustrates the steps performed during the assembling of the three webs to form pouches in accordance with this invention.

FIGURE 3 is a side perspective view of a novel pouch of this invention, and illustrates a body of the pouch house-d in a covering having notched side edge portions for facilitating the removal of the covering prior to a dispensing operation.

FIGURE 4- is a sectional view taken substantially along line 4-4 of FIGURE 3, and illustrates a nipple formed in the body of the pouch adjacent a bottom portion thereof.

FIGURE 5 is a fragmentary enlarged sectional view taken along line 5-5 of FIGURE 3, and illustrates the side edge connection of the pouch body and covering.

FIGURE 6 is a perspective View of the pouch after the covering has been partially removed, and illustrates the formation of a dispensing opening in the nipple prior to a dispensing operation.

Referring in particular to FIGURES 1 and 2 of the drawings, a web 10 of flexible polymeric material is drawn from a spool 11 by conventional pull rolls 19 to define a left-to-right predetermined path of travel of the web 10. The web 10 is preferably composed of approximately 2025 parts of ethylene-propylene copolymer rubber and approximately -80 parts of polypropylene containing aproximately 25 parts per million of Slip-Eze, a commercially available slip agent composed of the amides of several aliphatic fatty acids with the main constituent being olearnide. The thickness of the web 10 can be varied and is approximately 3 mil. The width of the web 10 is similarly variable depending upon the desired pouch height, and in accordance with this invention is approximately 11 inches wide.

The web 10 is drawn over the peripheries of a pair of

idle rollers

12 and 13 between which is suitably mounted a printing mechanism 14. The printing mechanism 14 includes an impression roll or cylinder 15 and a printing roll or cylinder 16. Suitable mechanisms well known in the prior art are employed to effect the application of printing material onto the peripheral surface of the printing cylinder 16. The cylinders 15 and 16 are rotated in synchronism in a manner well known in the prior art to transfer the printing material from the printing cylinder 16 to the web 10. The web 10 is preferably printed with indicia which, during the performance of a dispensing operation to be described more fully hereinafter, indicate the volume of material remaining in the pouch.

A portion 17 of the Web 10 is disposed in a generally horizontal plane between the roll 13 and a conventionally supported idler roll 18. A nipple forming mechanism 20 for cold-forming (or hot drawing) a plurality of longitudinally spaced nipples 21 to one side of a center line of the web is located between the

rolls

13, 18. Only the cold-forming mechanism is illustrated and comprises a male die 22 and a female die 23. The male die 22 underlies the portion 17 of the web 10 and includes a vertically reciprocal rod or plunger 24 which is an axial alignment with an aperture or opening 25 in the female die 25 overlying the portion 17 of the web 15. The plunger 24 is part of a conventional hydraulically operated fluid motor (unnumbered) which includes a conventional piston and cylinder (both also unnumbered). Upon the introduction of fluid pressure into the cylinder, the plunger 24 is rapidly driven upwardly as viewed in FIGURE 1 of the drawings toward and into the opening 25 of the female die 23. This upward ascent of the plunger 24 cold-forms each of the plurality of nipples 21. The cold-forming of the nip ples 21 reduces the wall thickness in comparison to the thickness of the web 18 and imparts a generally conical or cylindrical configuration to each of the nipples. It should also be noted that the stressed condition of each of the formed nipples causes the same to hug the plunger 24 as the latter descends, thereby inverting each nipple 21 as is best shown in FIGURE 1 of the drawings.

The diameter and length of the nipples 21 may vary and as an example, nipples have been cold-formed in accordance with this invention having a diameter of inch and a length of Ms inch when a plunger corresponding to the plunger 24 having a inch diameter draws web material through a inch diameter opening in a female die a distance of approximately 1 /8 of an inch.

After the nipples 21 have been formed in the web 10, the web 10 is drawn beneath and about a former 26 and between a pair of

rolls

27, 28 conventionally supported in a generally vertical plane. The former 26 folds the web 10 along a bottom longitudinal fold line 30 to bring opposite longitudinal edge portions 31, 32 (FIGURE 1) of the Web 10 into alignment opposite the folded portion 30.

A heat sealing mechanism 33 is conventionally supported upstream of the

rollers

27, 28 and comprises a pair of identical sealing members 34, 35 in aligned relationship on opposite sides of the folded web 10. The sealing members 34, 35 each include a pair of spaced sealing bar portions 36 (FIGURE 2).The sealing members 34, 35 are reciprocated toward and away from each other in timed relationship to the advancement of the web 10 to form parallel lines of heat sealing 37 spaced by an unsealed portion 38 (FIGURE 1) substantially midway between adjacent ones of the nipples 21 to form a plurality of connected pouch or pouch portions 40. The heat sealing temperature ranges approximately between 375 degrees F. to 400 degrees F., and each line of heat sealing 37 varies between inch to A inch in width with inch being optimum.

The pouches 40, when completely fabricated, are preferably encased in a covering formed by applying second and third webs 41, 42 respectively of flexible covering material to opposite faces of the folded web 10, in a manner best illustrated in FIGURE 2 of the drawings. The webs 41, 42 are each preferably constructed from Mylar, metallic foil, high density polyethylene or similar flexible material having a width in excess of the folded width of the web 10, as is best illustrated in FIGURE 1 of the draw ings. The second web 41 is drawn from a spool 43 (FIG- URE 2) supported conventionally in a vertical plane while the third web 42 is similarly drawn from an identical spool 44.

Guide rolls

44, 45 and 46, 47 guide the respective webs 41, 42 into overlying relationship to opposite faces of the folded web 10. Upper longitudinal edge portions 59 of the webs 41, 42 are in alignment with the edge portion 31, 32 of the folded web 10 while lower edge portions 51 project beyond the folded bottom portion 30 of the web 10 (FIG- URE 1).

The webs 41 and 42 are at least temporarily secured adjacent the edge portions 31, 32 of the folded web 10 by applying a strip or spot coating of adhesive material to the upper portions of each of the pouch portions 4t) by a pair of conventional adhesive applicator rolls 52, 53 supported downstream of the area at which the webs 41, 42 are applied to the folded web 10 (FIGURE 2). The adhesive is preferably of a pressure-sensitive type which unites the webs 19, 41 and 42 along the upper edge portions thereof upon the passage of these webs between the guide rolls 45, 47 which are preferably biased toward each other in a conventional manner to apply sufiicient pressure to unite these webs solely for a purpose to be described fully hereafter.

Immediately before the rolls 45, 47 is a mechanism 55 for forming a plurality of cut-outs or notches 56 between each or" the pair of parallel lines of heat sealing 37 of the web 10. The mechanism 55 is similar to the mechanism 20 and includes a female die 57 having a rectangularly shaped opening and a male die 58 in the form of a reciprocal plunger which is also generally rectangularly shaped (FIGURE 1). The

dies

57, 58 are suitably supported on opposite sides of the web 16 and upon reciprocation of the plunger 58 toward and into the opening (unnumbered) of the die 57 the cut-outs 56 are formed. These cut-outs facilitate the removal of the covering prior to a dispensing operation in a manner to be described fully hereafter.

After the notches 56 have been formed in the web 10 by the mechanism 55, the bottom edge portions 51 of the webs 41, 42 are joined to each other by a heat sealing mechanism 60 comprising a pair of reciprocal sealing members or sealers 6 1, 62 conventionally supported adjacent the bottom edges 51 of the respective webs 41, 42. As the sealers 61, 52 advance toward one another and contact the respective webs 41, 42 the webs 41, 42 are secured to each other but not to the web 10 along a relatively wide line of heat sealing 63 which is substantially equal to the distance between adjacent ones of the

spaces

38, 38 of the pouches 40.

Another heat sealing mechanism 65 comprising a pair of vertically disposed sealers 66, 67 is positioned between the pull rolls 12, 19 and the sealing mechanism 60. The sealers 55, 67 are movable by conventional means (not shown) toward each other in time relationship to the movement of the webs 10, 41 and 42 to form a vertical line of heat sealing 76 substantially midway between the spaced lines of heat sealing 37 to adhere the webs 10, 41 and 42 to each other on opposite sides of each of the nipples 21. The lines of heat sealing 70 extend completely from the

upper edge portions

31, 32 and 50 to the lowermost edge portions 51 of the webs 41, 42 and through the seal 63, as is best illustrated in FIGURE 1 to completely unite the webs 1G, 41 and 42. It should be particularly noted that along the portion of the lines of heat sealing 70 at which the four plies of the webs 10, 41 and 42 overlap these four plies are welded or joined together but beneath the folded bottom edge 36 of the web 10, and at the notches 56 the lines of heat sealing 70 only join portions of the webs 41, 42 to each other, but not to the web 10.

A dispensing device (FIGURE 1) is supported above the webs 10, 41 and 42 for charging each of the pouches 40 with a predetermined quantity of preferably a dispensable liquid product, such as milk, infant formula, water or a similar liquid. Each pouch 40 is filled to approximately three-quarters of its capacity, and in the present example, this is approximately four ounces of liquid in each of the approximately four and one-half by five and one-half inch pouches. 'Ilhe dispensing is facilitated by means of a vacuum mechanism 75, 77 positioned on opposite sides of the webs immediately below the dispensing mechanism 75 and substantially in vertical alignment therewith. Each of the vacuum mechanisms 76, 77 is substantially identical and includes a reciprocal tubular plunger 78 terminating in a suction head 80. The tubular plunger 78 of each of the vacuum mechanisms 76, 77 is connected to a suitable vacuum source, such as a vacuum pump, and the tubular plungers 78 are reciprocated in unison with respect to each other and in synchronism with the advancement of the webs.

As the webs 10, 41 and 42 pass beyond the pull rolls 19, 19 the longitudinal edge portions 31, 3-2 and 50 respectively are substantially in abutting relationship and in this form prevent the introduction of a dispensable product into the pouches 40. However, as each of the pouches approach the vacuum mechanisms 76, 77 the plungers 78 are advanced toward each other to contact the respec' tive webs 42, 41 adjacent the upper edge portions 50 thereof. The vacuum cups 80 grip these edge portions and, upon reciprocation of the plungers 78 away from each other, each of the pouches 40 is opened as is best illustrated in FIGURE 2 to receive the product from the dispensing mechanism 75. The adhesive applied by the rolls 52, 53 holds the webs 10, 41 and 42 together, as was heretofore noted, so that the inner web will travel along with the webs 41, 42 when subjected to the operation of the mechanisms 76, 77.

After each of the pouches 40 has been charged a pair of heat sealing members 82, 83 suitably positioned adjacent the

upper edge portions

50, 31, 32 of the webs are advanced toward each other to seal these edge portions and completely close each of the pouches 40. The sealing members 82, 83 are positioned in a horizontal plane above the plane of the adhesive applicator rolls 52, 53 and in this manner the adhesive applied by the rolls does not interfere with the sealing of the

edge portions

50, 31, 32 by the member 82, 83.

Beneath the sealers 82, 83 is a mechanism 68 for forming a diamond-shaped cutout or notch 69 in the webs in alignment with an uppermost portion of the cutout 56. The mechanism 68 is identical to the mechanism 55 except for the diamond configuration thereof, and a further description is unnecessary for a complete understanding of the invention. The diamond-shaped notch 69 is of a width not greater than half of the total width of the seal produced at the station 65.

A hollow reciprocal needle 85 is then introduced through the web 42 into the interior of each of the pouches 40 at a corner thereof. The needle 85 is connected to a suitable source of vacuum and all air entrapped in the pouches 40 during the sealing thereof by the heat sealing members 82, 83 is withdrawn.

After the air is withdrawn from each of the pouches 40, a pair of angularly arranged

heat sealing members

86, 87 are advanced toward each other to form a line of heat sealing 90 across the corner of each of the pouches and coverings to seal the same prior to the retraction of the hollow needle 85.

A conventional rotatable cutter 91 and backing roller 92 cooperate to sever the pouches and coverings along a line substantially midway between the lines of heat sealing 37 of the pouches 40. Between the time the pouches are charged and the time they are severed, a conveyor 93 provides the necessary support during this movement. However, upon the severance by the rotatable cutter 91 and the backing roller 92, the pouches and coverings forming a package generally referred to by the reference numeral 95 freely fall upon and are conveyed by an upper conveyor belt run 96 of a conveyor 97 into an autoclave 98. The autoclave 98 preferably includes two chambers (not shown), the first of which subjects the packages 95 to a live steam atmosphere of approximately ten pounds per square inch pressure for approximately twenty minutes. After a twenty minute time period, regulated by the speed of the conveyor 97, the packages pass from the first chamber to the second chamber (also not shown) of the autoclave 98. A pressure of approximately twelve pounds per square inch in an air atmosphere is maintained in the second chamber and the packages 95 remain therein until the packaged product is cooled below its boiling point. Each of the pouches 95 is then advanced beyond the autoclave 98 and the fabrication thereof is completed.

Referring to FIGURES 3 through 5 of the drawings, a novel package 100 corresponding to the packages of FIGURES 1 and 2 is illustrated and includes an inner pouch 101 and a covering 102.

The pouch 101 includes a nipple 103 adjacent a folded bottom edge portion 104 substantially midway between adjacent heat sealed side edge portions 105, 106 which terminate at an uppermost heated sealed portion 107 (FIGURE 4). The heat sealed side edge portions 105, 106 are respectively notched at 122, 123. The

notches

122, 123 correspond to the notch 56 formed by the mechanism 55 of FIGURES 1 and 2 after the packages 95 have been each severed by the cutter 91 and back-up roll 92. That is, as was heretofore noted, the cutter 91 divides the packages medially between the parallel lines of heat sealing 37, 37 and thus divides each of the cutouts or notches 56 into the

notches

122, 123 of the package 100.

Suitable indicia 108 in the form of inverted numerals is printed on the pouch 101 remote from the nipple 103. The numerals are preferably ounce marking, which, when the package is inverted from the position illustrated in FIGURE 3 during a dispensing operation to a position at which the nipple 103 is uppermost, indicate the amount of product remaining in the pouch 101 and thus indirectly indicate the amount of product consumed.

A line of heat scaling 110 across the corner of the pouch 101 formed by the edge portions 106, 107 seals a needle opening 111 in the pouch 101 to prevent contamination of the product packaged therein, the seal 110 corresponding to that produced by the

sealers

86, 87.

The covering web 102 comprises two substantially

identical covering webs

112, 112 corresponding to the webs 41, 42. Each of the covering webs 112 has an edge portion 113 heat sealed to the edge portions 107 of the pouch 101 and opposite side edge portions 114, 115 heat sealed to the respective side edge portions 105, 106 of the pouch 101 above the

notches

122, 123 but free of the pouch 101 and lower portions 116, 117 of the covering

webs

112, 112. These lower portions 116, 117 of the covering

webs

112, 112 are heat sealed only to each other and are identically V-notched at 120, 120. The notches correspond to the diamond-shaped notches 69 formed by the mechanism 68 prior to the severance by the cutter 91 to form the individual packages 95. Bottom edge portions 118 of the covering webs 112 are also heat sealed only to each other and in this manner the lower portion of the pouch 101 is free of the covering 102 downwardly of the notches 120 and along the bottom seam 118.

A dispensing operation is initiated by tearing either of the side edge portions 116, 117 of the covering 102 which is facilitated in the well known manner by the V-shaped notches 120. The pouch 101 is not ruptured during this severing because the same is unattached along the bottom edge portion 118 and the side edge portions 116, 117 as is best illustrated in FIGURES 3-5 of the drawings.

After the covering

webs

112, 112 whave been severed they are drawn to a position shown in FIGURE 6 to fully expose the nipple 103. Complete peeling of the covering

webs

112, 112 is unnecessary, and it is merely sufiicient to remove a sufiicient portion of the covering webs 112, adjacent the nipple 103 to expose the nipple and prevent the rougher severed edges of the

webs

112, 112 from contacting the face of an infant during a dispensing operation.

A hole 121 (FIGURE 6) is then pierced in the end of the nipple 103 with a sterile pin or similar sharp pointed tool. As was heretofore noted, the packaged product P is preferably milk, distilled water, or infant formula, and

the nipple is then placed into the infants mouth as slight pressure is exerted on the exterior of the pouch 101. This causes a flow of liquid through the hole 121 and at this point, the infant has adjusted the nipple "to its mouth and starts a sucking action which continues until the infants hunger is satisfied or the contents of the pouch are exhausted. Upon the completion of the dispensing or feeding operation, the package is discarded.

While a preferred embodiment of the invention has been thus far described, variations in the method of forming the packages, and thus altering the package construction are considered within the scope of this invention. For example, it may be desirable or unnecessary to provide the folded web 10 with the covering sheets or webs 41, 42 and the steps associated with the application of these webs to the folded web 10 may be eliminated. The individual uncovered pouches thus produced can, for example, be manually packaged in a separately fabricated outer pouch which is afterwards sealed in a manner in which the inner pouch is completely free of the outer pouch or covering.

During a dispensing operation performed in the manner heretofore described, the configuration of the nipples 21, 103 is maintained by applying manual pressure to the respective pouches 40 and 101. This is necessary because of the relatively thin wall construction of both the pouches and the nipples. However, it is also within the scope of this invention to provide means for maintaining the configuration of the nipples other than by the application of manual pressure to the pouches. One such means may be, for example, a mechanism disposed adjacent the nipple forming mechanism for injecting a predetermined quantity of plastic foam material into each nipple 21, and permitting the plastic material to foam and expand in situ. When fully set such foam material would partially or fully fill the nipples 21 and adhere thereto. A sufficient distance can be provided between the mechanism for injecting the foamable plastic material into each of the nipples 21 and the roll 18 to permit complete setting prior to the passage of each nipple 21 beyond the roll 18 and out of the generally vertical plane thereof. The roll 18 could be provided with a circumferential groove deeper than the length of the nipples 21 and Wider than the diameter of these nipples to provide a relieved area through which the nipples 21 freely pass during the movement of the web 10 over the periphery of the roll 18.

In lieu of the injection of foamable plastic material into the nipples 21, porous inserts corresponding to the internal configuration of the nipples 21 could be inserted into and bonded to each of the nipples 21. Such other alternatives as tubular inserts similarly insert into and bonded to each of the nipples 21 can also be employed in lieu of the porous inserts noted above.

The hollow needle 85 (FIGURE 2) and the

heat sealing members

86, 87 can also be eliminated and replaced by other suitable pouch vacuumizing means. For example, the area occupied by the heat sealing members 82, 83 can be completely enclosed within a vacuum chamber so that the charged pouches 40, upon passing therethrough, would become vacuumized and thereafter be immediately heat sealed by the heat sealing members 82, 83. Alternatively, a roller or other suitable mechanism can be provided at each side of the web 10 which would squeeze the charged pouches 40 during the passage thereof through the 'bight portions of the rolls sufiiciently to raise the liquid level of the package contents until the liquid product begins to overflow and at which time the heat sealing members 82, 83 would be actuated to seal the upper edge of the pouches. Still another alternative is to provide, immediately before the heat sealing members 82, 83, a superheated steam line for injecting steam into the charged pouches 40 to thereby flush the air therefrom, the heat sealing operation following immediately thereafter.

From the foregoing, it will be seen that novel and advantageous provisions have been made for carrying out the desired end. However, attention is again directed to the fact that additional variations may be made in this invention without departing from the spirit and scope thereof as defined in the appended claims.
