Abstract
Description
- The present invention relates generally to flexible containers for liquids and gels, and dry contents, and more particularly to a disposable flexible pouch with a removable strip that can be pulled to gain access to the contents of the pouch.
- Flexible beverage containers are well known in the art, with many shapes and sizes. Common configurations include pouches with straw holes that can be punctured to permit access to the beverage contained therein. Other types of packages include those with spouts, including threaded spouts that employ a twist-off cap. U.S. patent application Ser. No. 11/471,930 filed Jun. 21, 2006 by the present inventor and assigned to the present assignee discloses a method for attaching a spout to a flexible container, and the contents of that application are incorporated fully herein by reference. Another method is a “cut and pour” type of emptying the contents of a stand-up pouch (a pouch with the gusset on the bottom of the pouch).
- While twist-off spouts can be utilized effectively in certain conditions, detachable caps can be misplaced or lost. If a mode of access can be improved to make it easier to open the container, this improved mode will enjoy success in the market place. However, there are many difficulties that arise when working with thin films that form the body of flexible beverage pouches, and it is important to be cognizant of waste and spillage that can arise by poorly constructed opening mechanisms that cause premature puncture or are too difficult to open. There is a need in the art for a pouch with an opening mechanism that is both secure, sterile, and easy to implement in conjunction with thin film pouches. Many stand-up pouches (gusset on the bottom) use a simple method of opening with just a cut and pour feature, although the results of using this method can be messy and not re-closable. However, with a side gusseted pouch, one cannot easily cut the top of this pouch and pour, as cutting the top will jeopardize the structure of the pouch and may cause the contents to spill. The present invention provides a low cost solution for both pouch types, including other pouch shapes as well.
- The present invention is characterized by a thin film pouch with a front wall, and rear wall, and an opening in said front wall, and further comprising a closure mechanism comprising a thin membrane patch bonded to said pouch about a periphery of said opening, a platform bonded to said thin membrane patch, said platform including a window formed therein and a plurality of cutting surfaces adjacent said window, and a pull strip bonded to said thin membrane patch and attached to said platform by a frangible membrane, wherein a removal of the pull strip ruptures said frangible membrane and tears said thin membrane patch at said cutting surfaces.

FIGS. 1 a-1 c illustrate a flexible pouch having a pull strip as part of a zip release opening that can be actuated to tear an elongate strip of pouch away from the body of the pouch to gain access to the contents therein. Thepouch 10 includes a body having abase 12, afront surface 14, arear surface 16,side surfaces 18, and atop 20. The pouch may have a gable design as shown, or can take the form of a brick, triangular, or pillow-shaped pouch. Thepouch 10 may be created by any of the many known techniques for formulating a closed container that incorporates a thin walled member. As further shown inFIG. 1 , thepouch 10 of the present invention includes apull strip 22 including afree end 22 a that can be grasped between a thumb and forefinger to actuate the zip release opening 25. Thefree end 22 a of thepull strip 22 preferably includes a grasping member can take many forms, such as aspherical anchor 24, annular ring, or flat tab with ridges that can be easily grasped. Thepull strip 22 is pulled back to engage thethin wall 32 of the pouch's outer skin, and then retracted to tear open anelongate aperture 25 on thepouch 10 to expose the pouch's interior. When thepull strip 22 is fully retracted as shown inFIG. 1 c, thecontents 28 of thepouch 10 can be poured out or otherwise accessed in an expeditious manner as shown inFIG. 2 . Note that thepouch 10 can be formed with apouring ledge 30 or other spout structure to prevent fluid from dribbling down thefront surface 14 of the pouch during pouring. The coupling of thepull strip 22 to the pouch will now be described in more detail. -
FIGS. 3 and 4 illustrate the operation of thepull strip 22 from initial deployment to full release. As shown inFIG. 4 , thepull strip 22 comprises an elongateplastic strip 36 that is affixed to arectangular platform 38 with anelongate window 44 disposed therein and covered by theplastic strip 36. On theborder 39 of theplatform 38 that defines thewindow 44 are first and second rows of downwardly directedcutting teeth 42 along each longitudinal edge, and alarger cutting tooth 46 at an edge where thefree end 22 a is located. InFIG. 3 a, theplatform 38 is bonded to athin membrane patch 41 that connects theplatform 38 to theedge 32 of the pouch. Theplastic strip 36 is also bonded to thethin membrane patch 41 a, where the bonding of theplastic strip 36 to themembrane patch 41 a is surrounded by thecutting teeth patch 41 aand thepatch 41 at the perimeter of theplatform 38 is a slightly raised surface 37 (FIG. 3 a). Thecutting teeth surface 37 of themembrane patch 41 prior to actuation of thepull strip 22. As thepull strip 22 is initially lifted as shown inFIG. 3 b, theplastic strip 36 begins to separate from theplatform 38, and thethin film membrane 41 a attached to theplastic strip 36 is pulled upward against thecutting teeth 42. Thecutting teeth 42 pierce thethin membrane 41, beginning with thetooth 46, as shown inFIG. 3 b. As theplastic strip 36 is further pulled away from theplatform 38 as shown inFIG. 3 c, the portion of themembrane 41 a that is bonded to the lower surface of theplastic strip 36 is retained by theplastic strip 36 as thecutting teeth 42 sever the surrounding membrane, creating anaperture 25 in the pouch through thewindow 44 of theplatform 38.FIG. 3 d shows the pouch opening with theplastic strip 36 separated from theplatform 38 to fully expose thewindow 44 and create the pour spout for the pouch. -
FIG. 5 a shows a cross-sectional view of the closure prior to actuation of thepull strip 22. Theplastic strip 36 carries thepull tab 24 at a proximal end, and rests betweenedges 39 of theplatform 38.Cutting teeth 42 are disposed along theedges 39 and project below the lower surface of theplatform 38. Thepatch plastic strip 36 and the bottom surface of the platform on opposite sides of thecutting teeth 42. To enhance ultrasonic bonding of theplatform 38 and theplastic strip 36 to themembrane 41, small raised tabs can preferably extend from those surfaces where said bonding occurs. Theplastic strip 36 is attached to thecutting teeth frangible sheet 47 in a septic embodiment shown inFIG. 5 . Thethin sheet 47 is severed when thepull tab 22 is actuated, separating theplastic strip 36 from thecutting teeth 42 as shown inFIG. 5 b. This embodiment is aseptic because the plastic strip never contacts the contends of the pouch, but rather the pouch is preserved in an aseptic condition until it is opened. InFIG. 6 a, an alternative embodiment is illustrated (non-septic) where thethin membrane 41 a is omitted. Here, theplatform 38 is bonded to themembrane patch 41, which in turn is bonded to the outer edge of thepouch 10. Thepull strip 22 is connected to theplatform 38 by athin sheet 47, but thebottom surface 51 of theplastic strip 36 is exposed to the interior of thepouch 10. As shown inFIG. 6 b, when thepull strip 22 is actuated, thesheet 47 is severed and thewindow 44 of theplatform 38 is thereby exposed. In this embodiment, thecutting teeth FIGS. 7 a and 7 b illustrate another embodiment of the closure that can be re-closed after opening. Theplatform 38 is formed with retainingledges 55 a,b that extend slightly over the outer edges of theplastic strip 36. After thepull tab 22 is actuated and thesheets 47 are ruptured, the contents of the pouch can be accessed. If it is desired to re-close the opening, theplastic strip 36 can be returned to theplatform 38 and the retainingledges 55 a,b flex to allow the plastic strip to return to theplatform 38 where it is held in place by the retaining ledges. Although the aseptic condition has been eradicated by the opening of theplastic strip 36, for short term usages a simple resealing of the pouch is all that is needed. A non-septic version (seeFIG. 6 ) can also be made with a re-closable closure as just described. - The closure of the present invention can be made of any sturdy plastic such as polyethylene or polypropylene, as long as economic bonding techniques such as, for example, ultrasonic bonding, will work with the plastic. Because the closure is molded in the closed position, it can be made from a single cavity mold, which is atypical for this type of closure. Using a single cavity mold significantly reduces the costs of manufacturing the closure, making the present invention very economical compared with alterative closure means.
- The foregoing descriptions are intended to be illustrative of various embodiments within the scope of the present invention, and are not intended to be limiting or exclusive. One of ordinary skill in the art would readily appreciate many alternatives and deviations from those embodiments described above, and the invention is intended to include all such alternatives and deviations. Accordingly, the scope of the invention should be construed according to the ordinary meaning of the terms set forth in the appended claims in view of the foregoing descriptions.
