Definitions
- the present disclosure relates generally to beverage containers, and more particularly to a collapsible beverage pouch with a push-pull fitment.
- Flexible containers made from paperboard or metal foil are often used to package various beverages for retail distribution. These flexible containers are often packaged with a separate straw wrapped in cellophane and secured to the outside of the container. The straw may be removed by the consumer and used to puncture a sealed spout as the straw is inserted into the container. Once the straw is inserted, the consumer may withdraw the beverage from the container.
- the use of a straw secured to a beverage container has numerous drawbacks.
- Packaging a straw together with the container can be costly and inefficient, requiring not only an additional manufacturing step to make the straw and cellophane wrap, but yet another manufacturing step to wrap the straw with the cellophane and secure it to the container.
- the cellophane wrap is discarded, resulting in waste.
- the insertion of the straw through the sealed spout into the container can also be difficult, and often results in the beverage squirting up through the spout. If the entire beverage is not consumed, then it will go to waste for there is no easy way to reseal the spout once it is punctured.
- the straw is prone to dislodge from the container before use, making the consumption of the beverage very difficult, if not impossible.
- the beverage container should not require the use of a straw to consume the beverage and should have a mechanism to reseal the container in the event that the beverage is not completely consumed.
- a beverage container in one aspect of the present invention, includes a flexible stand-up pouch consisting essentially of polyester and polyethylene.
- the pouch includes two wall panels with a corner section cut out to form a slanted edge.

Description
- The present application is a continuation of copending patent application, Ser. No. 10/752,631, filed Jan. 7, 2004, entitled “BEVERAGE CONTAINER,” the entire content of which is hereby incorporated by reference.
- 1. Field
- The present disclosure relates generally to beverage containers, and more particularly to a collapsible beverage pouch with a push-pull fitment.
- 2. Background
- Flexible containers made from paperboard or metal foil are often used to package various beverages for retail distribution. These flexible containers are often packaged with a separate straw wrapped in cellophane and secured to the outside of the container. The straw may be removed by the consumer and used to puncture a sealed spout as the straw is inserted into the container. Once the straw is inserted, the consumer may withdraw the beverage from the container.
- The use of a straw secured to a beverage container has numerous drawbacks. Packaging a straw together with the container can be costly and inefficient, requiring not only an additional manufacturing step to make the straw and cellophane wrap, but yet another manufacturing step to wrap the straw with the cellophane and secure it to the container. When the consumer uses the straw, the cellophane wrap is discarded, resulting in waste. The insertion of the straw through the sealed spout into the container can also be difficult, and often results in the beverage squirting up through the spout. If the entire beverage is not consumed, then it will go to waste for there is no easy way to reseal the spout once it is punctured. Moreover, the straw is prone to dislodge from the container before use, making the consumption of the beverage very difficult, if not impossible.
- Accordingly, there is a need for a beverage container that is commercially viable to produce for retail distribution. The beverage container should not require the use of a straw to consume the beverage and should have a mechanism to reseal the container in the event that the beverage is not completely consumed.
- In one aspect of the present invention, a beverage container includes a flexible stand-up pouch consisting essentially of polyester and polyethylene. The pouch includes two wall panels with a corner section cut out to form a slanted edge. A push-pull fitment extends from the slanted edge of the pouch.
- In another aspect of the present invention, a beverage container includes a flexible stand-up pouch consisting essentially of polyester and polyethylene. The pouch includes a base, and two wall panels joined to the base, with the wall panels being peripherally sealed to one another along two opposing lateral edges and a top edge so as to define an interior region suitable for containing a beverage. The top edge includes a slanted edge portion with a push-pull fitment extending therefrom.
- In another aspect of the present invention, a beverage container includes a flexible stand-up pouch consisting essentially of polyester and polyethylene. The pouch includes first and second lateral edges and a top edge having first and second portions, the first portion being substantially perpendicular to the first lateral edge, and the second portion extending from the first portion to the second lateral edge so as to form an obtuse angle between the first and second portions and an obtuse angle between the second portion and the second lateral edge. A push-pull fitment extends from the second portion of the top edge.
- It is understood that other embodiments of the present invention will become readily apparent to those skilled in the art from the following detailed description, wherein various embodiments of the invention are shown and described by way of illustration. As will be realized, the invention is capable of other and different embodiments and its several details are capable of modification in various other respects, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not as restrictive.
- Aspects of the present invention are illustrated by way of example, and not by way of limitation, in the accompanying drawings, wherein:
-
FIG. 1 is a perspective view showing a beverage container with a flexible stand-up pouch; -
FIG. 2 is a diagrammatic vertical section of a flexible stand-up pouch with a base in the collapsed position; -
FIG. 3 is a front elevation view of a flexible stand-up pouch with a base in the collapsed position; -

FIG. 1 is a perspective view showing a beverage container having a flexible stand-up pouch 102. The pouch may be constructed with twowall panels 104 with a corner section cut out at the top of thepouch 102 to form a slanted edge 106. A push-pull fitment 108 extending from the slanted edge 106 may be used by the consumer to dispense the beverage from thepouch 102. The term “push-pull fitment” means a fitment having a cap that moves up and down a stem to open and close the fitment. By way of example, a cap 110 shown inFIG. 1 may be “pulled” up thestem 112 to open thefitment 108 and “pushed” down thestem 112 to close thefitment 108. - In at least one embodiment of the beverage container, the push-
pull fitment 108 may be formed with a tamper-evident seal. This may be achieved during the manufacturing process by heat-sealing the bottom portion of the cap 110 to thestem 112 with thefitment 104 in the closed position. The tamper-evident seal may be broken by the consumer by simply twisting the cap 110. - The physical dimensions of the
pouch 102 may vary depending on manufacturing preferences and the particular application. For retail distribution of beverage drinks, commercial viability may best be served with a small, lightweight construction. By way of example, thewall panels 104 may have a lateral height of 160 mm and a horizontal length of 110 mm. The slanted edge 106 may be formed at 45° angle for easy consumption of the beverage from thepouch 102 through the push-pull fitment 108. - The lightweight construction of the beverage container may be achieved by selecting the appropriate material. By way of example, the
pouch 102 may be formed from a polyester, polyethylene laminate. The polyethylene layer may provide a heat-sealable interior lining for thepouch 102. Because the polyester does not shrink during the heat-sealing process, various aesthetic features and written materials may be printed on the polyester layer before thepouch 102 is constructed without experiencing distortion during the heat-sealing process. The thickness of the polyester film may be about 12 microns and the thickness of the polyethylene may be about 90 microns. Other material thicknesses may be used where appropriate. - The
pouch 102 may be constructed with a collapsible base joined to the twowall panels 104.FIG. 2 is a diagrammatic vertical section of a pouch with the base collapsed, andFIG. 3 is an elevation view of the same pouch with the base collapsed. In the collapsed form, the base may be formed with agusset panel 202 interposed and folded inwardly between the twowall panels 104. Each section of the gusset panel 202 a and 202 b may be joined to one of thepanel walls 104 with a “bottom”seal 204 and twooblique seals 206. For the purposes of this disclosure, the “bottom” of the pouch will refer to the base portion of thepouch 102 regardless of the orientation of the pouch. The gusset panel construction allows the base to be expanded to support thepouch 102 in a standing or upright position with a generally elliptical unsealedarea 208 inward of the bottom andoblique seals FIG. 4 . An example of this type of gusset panel is disclosed in U.S. Pat. No. 3,380,646, entitled Container of Plastic Material and Method of Producing the Same, the contents of which is incorporated herein by reference. - Referring to
FIGS. 2-4 , the twowall panels 104 may be fastened to one another bylateral seals 210 so as to define an interior region suitable for containing the beverage. An opening at the “top” of thewall panels 104 establishes communication between the pouch interior region and the exterior of the pouch. The opening may be adapted to receive the push-pull fitment along the slanted edge 106. For the purposes of this disclosure, the “top” of the pouch will refer to the edge of thepouch 102 having the fitment regardless of the orientation of the pouch. Once the push-pull fitment is secured between the twowall panels 104, thepouch 102 may be filled with a beverage through the top, and then the twowall panels 104 may be fastened together with atop seal 212. - An example of a push-
pull fitment 108 is shown inFIGS. 5 and 6 .FIG. 5 is a partial cross-section view of the fitment in the closed position with portions broken away, andFIG. 6 is a partial cross-section view of the fitment in the open position with portions broken away. Thefitment 108 may be molded from a polymeric material, such as high density polyethylene, which is suitable to be sealed between the two wall panels. Thefitment 108 may include abody 502 and acap 504. - The
body 502 may be formed with ahollow base 506 having generally a canoe-shaped configuration with anopen bottom 510, atop deck 512, and twoside walls 514 converging at two opposing ends. Eachside wall 514 may have a series of spacedribs 516 which may be heat sealed to a corresponding wall panel of the pouch. - The
body 502 may also include thestem 112, which may be a hollow annular body positioned on thetop deck 512 and aligned with the base 506 so as to form a dispensing passage that extends through thefitment 108. Thestem 112 may include abottom flange 520 and anannular channel 524 bound by anupper flange 526 and abottom portion 522 of thestem 112. Aclosure plug 528 extending above thestem 112 may be anchored to the interior portion of thestem 112 with a number of circumferentially spaced upwardly and angularly extendinglegs 529. - The
cap 504 may be formed with a hollowannular wall 530 and atop portion 532 with acentral opening 534. The interior portion of theannular wall 530 may include an inwardannular flange 536. An interiorannular ring 538 may extend downward from thetop portion 532 of thecap 504. The ring 540 in combination with the upper portion of the interiorannular wall 530 form an annular channel adapted to receive thestem 112. - The
cap 504 may be positioned on thebody 502 of thefitment 104 so that theannular flange 536 extending inward from the interior of theannular wall 530 of thecap 504 slideably engages theannular channel 524 of thestem 112. Thefitment 108 may be closed by moving thecap 504 down thestem 112 of thefitment 108 until theannular flange 536 extending inward from the interior of theannular wall 530 of the cap hits thebottom portion 522 of thestem 112, thus forcing theclosure plug 528 into thecentral opening 534 of thecap 504 as shown inFIG. 5 . With theclosure plug 528 lodged into thecentral opening 534 of thecap 504, the beverage in the interior pouch region is completely sealed off from the exterior of the pouch. Thebottom portion 522 of thestem 112 acts as a stopper limiting the downward movement of thecap 504 on thestem 112. - The fitment may be opened by moving the
cap 504 up thestem 112 until theannular flange 536 extending inward from theannular wall 530 of thecap 504 hits theupper flange 526 of thestem 112, thus removing the closure plug 528 from thecentral opening 534 of thecap 504 and establishing communication between the pouch interior region and the exterior of the pouch through thecentral opening 534 of thecap 504 at the end of the dispensing passage. The fitment in the opened position is shown inFIG. 6 . Theupper flange 526 acts as a stopper limiting the upward movement of thecap 504 on thestem 112. - The collapsible beverage pouch may be fabricated in any number of ways, including manually or through an automated process.
FIG. 7 is a perspective view of a horizontal in-line machine 702 that may be used to form, seal, and fill the pouch in an automated fashion. - The horizontal in-
line machine 702 may be configured to continuously feed flat sheets of pouch material into apouch forming plough 710 from a single roll of thepouch material 706. The formingplough 710 may be used to form the gusset panel and then fold the sheet lengthwise. - Once the sheet is formed, the horizontal in-
line machine 702 may perform a number of steps to seal and separate the sheets into individual pouches. Abottom seal unit 712 may be used to provide the bottom and oblique seals by pressing the pouch material together in each section of the gusset panel using hot iron bars or other similar device that binds the polyethylene interior lining together. Aside seal unit 714 following thebottom seal unit 712 may be used to provide the lateral seals by pressing the pouch together with hot iron bars or similar device that extends the height of the wall panels and base of the pouch. Acutting unit 716 may follow theside seal unit 714 to cut the sheet into individual pouches. Thecutting unit 716 may be implemented with a pair of vertically spaced scissors or blades. In at least one embodiment, theside seal unit 712 and thecutting unit 714 may be integrated so that both operations may be performed in a single step. Either way, the cut pouches may be fed into acooling unit 718 to cure the heat seals. - Once the pouches are separated and sealed, a fitment may be fixed to each pouch. A
corner cutting unit 720 may be used to remove a corner from each pouch. Thecorner cutting unit 720 may be implemented with a blade angled at 450 or other suitable angle. Once the corner of the pouch is removed, the pouch may be fed to asuction cup 722 to open the pouch before the fitment is attached by thefitment insertion unit 724. Afitment feeder unit 726 may be positioned above thefitment insertion unit 724. Thefitment feeder unit 726 may include acontainer 728 which ejects fitments onto a track 730. The track 730 may be used to guide the fitment from thecontainer 728 to the pouch so as to align the base of the fitment with the cut-away corner section of the pouch between the two wall panel. Once the fitment is aligned, the pouch may be forwarded to afitment welding unit 732. Thefitment welding unit 732 may use two heated iron bars to press the two wall panels of the pouch against opposing sides of the fitment base. Thefitment welding unit 732 may also be used to heat seal the bottom of the cap 110 to thestem 112 to provide a tamper-evident fitment. - Once the fitment is fixed to the pouch, the horizontal in-
line machine 702 may be used to fill the pouch. A blowingcone 734, following thefitment welding unit 732, may be used to open the top of the pouch before being fed to a filling station 736. The filling station 736 may be used to fill the pouch with a beverage. - Once the pouch is filled, it is ready to be completely sealed. The filled pouch may be fed to a stretching unit 738, which may be used to elongate the pouch and drive the air out of the pouch before being fed to a
top seal unit 740. Thetop seal unit 740 may be used to heat seal the top of the pouch using a pair of hot horizontal iron bars applied to the top of the opposing wall panels. The finished product may then be deposited on anoutlet conveyer unit 742. - The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
