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.

Claims (22)

1 . A closure mechanism for a thin walled pouch comprising:

a thin membrane patch secured to said thin walled pouch;

a platform bonded to said thin membrane patch, said platform formed with a window and a plurality of downwardly directed cutting surfaces; and

an elongate removable strip overlaying said window and connected to said platform by a frangible member, said frangible member ruptured by removal of said elongate strip.

2 . The closure mechanism of claim 1 wherein said elongate removable strip is bonded to said thin membrane patch, and removal of said elongate strip tears said thin membrane patch along said cutting surfaces.

3 . The closure mechanism of claim 2 wherein said elongate removable strip has a pull tab.

4 . The closure mechanism of claim 2 wherein said cutting surface comprise a plurality of downwardly directing teeth.

5 . The closure mechanism of claim 2 wherein said platform includes first and second retaining ledges to retain said elongate removable strip against said platform after said frangible member is ruptured.

6 . The closure mechanism of claim 1 where said platform is ultrasonically bonded to said thin membrane patch.

7 . The closure mechanism of claim 1 wherein said closure mechanism is made of polyethylene.

8 . The closure mechanism of claim 1 wherein said closure mechanism is made from a single cavity mold process.

9 . A thin walled disposable pouch having 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;

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.

10 . The pouch of claim 9 wherein said elongate removable strip has a pull tab.

11 . The pouch of claim 9 wherein said cutting surface comprise a plurality of downwardly directing teeth.

12 . The pouch of claim 9 wherein said platform includes first and second retaining ledges to retain said elongate removable strip against said platform after said frangible member is ruptured.

13 . The pouch of claim 9 where said platform is ultrasonically bonded to said thin membrane patch.

14 . The pouch of claim 9 wherein said closure mechanism is made of polyethylene.

15 . The pouch of claim 1 wherein said closure mechanism is made from a single cavity mold process.
