Definitions
- Beverages such as juice have been sold in flexible pouches made from plastic film.
- the pouches are typically triangular in vertical cross-section and have flat bottoms which support the pouches in a stand-up position.
- Some pouches are products with openings for insertion of a drinking straw. However, the pouch must remain sealed before use.
- the invention relates to a pouch and a method for forming a pouch with a weakened portion of a wall.
- the weakened portion is formed to permit a straw to pierce the weakened portion to permit access to a beverage contained in the pouch.
- the pouch is formed of a web of flexible material such as plastic film.
- a dimple is formed in a mold under heat and pressure to weaken the film.
- the locating indicia such as a circle, is printed on the web around the dimple.
- a removable patch is placed over the dimple.
- the method of manufacture includes forming a locating indicia on a web of flexible material and a registration mark for registering a web, indexing the web at a molding station, pressing and heating a portion of the web in a mold to form the dimple and then forming a pouch from the web.
- a first preferred alternative embodiment suitable for use with a pouch formed of a web having a layer of metal foil includes cutting partially through the laminate with a laser to form a frangible portion for piercing by the straw.
- a second preferred alternative embodiment includes bonding a port to the pouch.
- the port includes a frame member having an aperture covered by a removable membrane.
- the membrane is a strip of plastic or metal foil which is adhered to an inner side of the frame member.
- the port is bonded to the wall to cover an aperture formed therein.
- the membrane is affixed to the frame by an adhesive which separates upon pressure from the straw during piercing.
- the frame provides a target for guiding the straw.

Description
- This application claims the benefit of U.S. Provisional Application No. 60/270,037, filed Feb. 20, 2001 and U.S. Provisional Application No. 60/339,934, filed Dec. 10, 2001.
- Beverages such as juice have been sold in flexible pouches made from plastic film. The pouches are typically triangular in vertical cross-section and have flat bottoms which support the pouches in a stand-up position. Some pouches are products with openings for insertion of a drinking straw. However, the pouch must remain sealed before use.
- As disclosed in U.S. Pat. No. 5,868,658 to Wild, it is known to form an aperture through one wall of the pouch. The wall is formed of two layers of film. A third layer of film in the form of a strip is welded about the aperture to the inner surface of the film. The aperture through the wall of two layers is covered. The contents of the pouch are accessed by inserting the straw through the aperture formed in the wall and then piercing the third layer of film. It is also known to use pull-off tabs which are used to cover the preformed aperture.
- However, these and other such methods include the use of extra materials or are complex to form. The additional layers of material or tabs add financial cost to the cost of producing the pouch. Accordingly, it would be desirable to eliminate the use of additional tabs or strips of material in producing a straw pierceable pouch.
- The invention relates to a pouch and a method for forming a pouch with a weakened portion of a wall. The weakened portion is formed to permit a straw to pierce the weakened portion to permit access to a beverage contained in the pouch.
- In one embodiment suitable for beverages, the pouch is formed of a web of flexible material such as plastic film. A dimple is formed in a mold under heat and pressure to weaken the film. The locating indicia, such as a circle, is printed on the web around the dimple. A removable patch is placed over the dimple. The method of manufacture includes forming a locating indicia on a web of flexible material and a registration mark for registering a web, indexing the web at a molding station, pressing and heating a portion of the web in a mold to form the dimple and then forming a pouch from the web.
- A first preferred alternative embodiment suitable for use with a pouch formed of a web having a layer of metal foil includes cutting partially through the laminate with a laser to form a frangible portion for piercing by the straw.
- A second preferred alternative embodiment includes bonding a port to the pouch. The port includes a frame member having an aperture covered by a removable membrane. The membrane is a strip of plastic or metal foil which is adhered to an inner side of the frame member. The port is bonded to the wall to cover an aperture formed therein. The membrane is affixed to the frame by an adhesive which separates upon pressure from the straw during piercing. The frame provides a target for guiding the straw.

ring 20 is formed about the dimple in a suitable manner, such as printing, to permit easy identification of the dimple. Aprotective cover 22 may be placed over the dimple with an adhesive which permits removal by atab 24 to prevent inadvertent puncture during transportation and storage. - The
pouch 10 may be formed on conventional pouch manufacturing equipment, including horizontal form-fill-seal machines, flat bed pre-made pouch machines, or vertical form-fill-seal machines. These machines form the pouches from a roll of the plastic film. The film is preprinted with labeling and other packaging information. The locating indicia orring 20 is preprinted along with registration marks 26 (FIG. 3). The film is taken from a roll and formed into aweb 28 of two to four layers of film. - As shown in FIG. 3, the
web 28 is then moved to amolding station 30. Theregistration mark 26 is read by ascanner 32 to index theweb 28 at themolding station 30. Themolding station 30 includes amale mold element 34 and afemale mold element 36. Thefemale mold element 36 includes aheating element 38 and has aparabolic cavity 40 to receive theweb 28. Themale mold element 34 includes aheated rod 42 having a parabolic shapedend 44 complementary to the shape of thefemale mold element 36. Themale mold element 34 is connected to an apparatus (not shown) which raises and lowers the male mold element. - The web is indexed to position the locating
indicia 20 around thecavity 40 of thefemale mold element 36 and themale mold element 34 is moved downwardly to compress the web briefly between the male andfemale mold elements - As shown in FIGS. 4 and 5, a
parabolic dimple 12 is formed in the web. Because heat shrinks plastic, thedimple 12 has a thickness thinner than the remainder of the web. For instance, a web having a thickness of 4 gauge is reduced in thickness to approximately 2 gauge after being molded to form thedimple 12. - As shown in FIGS. 4 and 5, the parabolic dimple assumes a somewhat triangular cross-section when pressed by the pointed end of the
straw 16. Thedimple 12 then takes a triangular shape with ashorter wall 46 transverse the point and alonger wall 48 which extends generally parallel to the axis of the straw as it is being pressed downwardly towards the bottom of the pouch. Thus, thelonger wall 48 of the dimple acts to guide the straw through thedimple 12 into thepouch 10. - As shown in FIGS.6-11, a first alternative preferred embodiment of the invention includes a
pouch 60 with afrangible flap 62 cut with a laser in thewall 63. - The first alternative preferred embodiment is particularly suited for a pouch formed from a web having one or more layers of metal foil. The foil layers do not deform when heated.
- As shown in FIG. 7, a
web 64 for forming the pouches has four layers of material. The web has anouter layer 66, asecond layer 68 andinner layer 72 of a plastic web, and athird layer 70 of foil. - The
flap 62 is cut in the top, second, andthird layers cut 74 having an arc of 270°-300°, as shown in FIG. 8. Theflap 62 remains connected to thewall 63 by astrip 76 to prevent the flap from falling into the pouch. A piercingindicator 78 may be formed on the flap to indicate a target for thestraw 16. - The
flap 62 is formed in theweb 64 at a cuttingstation 80 as shown in FIG. 9. After theweb 64 is formed and moved to the cuttingstation 80, ascanner 32 reads theregistration mark 26 to index theweb 64 at the desired location. - As shown in FIG. 9, the cutting
station 80 includes alaser cutting unit 82 which is stationed aboveplatform 84 supporting the film. A controller (not shown) then activates the cuttingunit 82 to form the circular cut 74 partially through the film. The cuttingunit 82 is controllable to cut to a precise depth so that although the wall is weakened, it remains intact. A piercingindicator 78 may also be used to bond the layers of the web together in a ring around thecut 74 formed by the cutting unit. - As shown in FIG. 10, the
inner layer 72 of thewall 63 is pierced when pressed by the pointed end of the web. The piercingindicator 78 cut in the wall facilitates location of the point of thestraw 16. As theflap 62 is pushed by thestraw 16, the remaininginner layer 72 of material is pierced to permit entry of thestraw 16 into the pouch. - A second preferred embodiment of the invention is shown in FIGS.12-14. As shown in FIG. 12, a
pouch 90 having aport 94 for insertion of thestraw 16 is thereshown. - As shown in FIGS. 13 and 14, the
port 94 includes a moldedframe 96 and aflexible membrane 98 extending over anaperture 105 formed in theframe 96. Theframe 96 is formed of a moldable material such as nylon or polyethylene. Theframe 98 has aflat mounting surface 100 on one side. Acircumferential wall 106 defines anaperture 105 for receiving and guiding thestraw 16. Although theframe 102 is shown as having a circular profile, the profile may be any shape, such as a star or rectangle. Thewall 106 defining theaperture 105 of theframe 96 has sufficient diameter or width to accept thestraw 16 therebetween. Themembrane 98 is formed from either plastic film or metal foil. Themember 98 is bonded to theflange 102 of the frame member by a suitable method. In most applications, themembrane 98 is a laminate having a top layer of heat shrinkable plastic material such as polyethylene and polyester. The membrane 8 is thus affixed by heat shrinking as is known in the art. In the case of some materials it is desirable to use an adhesive which separates when the straw impacts the membrane. The port is attached to an inner surface of theweb 92 in a suitable manner, such as ultra-sonic welding. - An
aperture 104 is formed in the web at a cutting station having dimensions complimentary with theaperture 106 in the frame. The web is moved to a mounting station where an arm places the mounting surface of the frame on an inner surface of the web. The port is sonically welded to the web. Themembrane 98 is accessible through theaperture 104 in the web. The web is then trimmed into panels and formed into a pouch in the conventional manner. - In this way, a straw-pierceable membrane is affixed to the pouch permitting using effective straw-pierceable access to the contents of the pouch. While specific embodiments of the invention have been shown, described to illustrate the present invention, it is to be understood that the invention may be embodied otherwise without departing from the principals. For example, one skilled in the art will recognize from such a discussion and the accompanying drawings and claims that various modifications and variations can be made without departing from the spirit and scope of the invention as defined in the following claims.
