Problems solved by technology

While twist-off spouts can be utilized effectively in certain conditions, detachable caps can be misplaced or lost.
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.
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.

Embodiment Construction

[0017]FIGS. 1a-1c 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. The pouch 10 includes a body having a base 12, a front surface 14, a rear surface 16, side surfaces 18, and a top 20. The pouch may have a gable design as shown, or can take the form of a brick, triangular, or pillow-shaped pouch. The pouch 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 in FIG. 1, the pouch 10 of the present invention includes a pull strip 22 including a free end 22a that can be grasped between a thumb and forefinger to actuate the zip release opening 25. The free end 22a of the pull strip 22 preferably includes a grasping member can take many forms, such as a spherical anchor 24, annular ring, or flat tab with ridges that can be easily grasped. ...

Abstract

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.

Description

BACKGROUND[0001]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.[0002]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).[000...
