First Claim
Patent Images
1. A flexible multiple-compartment beverage pouch comprising:
- (a) a first sheet of polymeric film;
(b) a second sheet of polymeric film superimposed on said first sheet of polymeric film wherein said first and second sheets of polymeric film are sealed to each other directly or indirectly through a third intervening polymeric film thus defining a sealed perimeter forming a closed pouch;
(c) at least one frangible seal internal to the perimeter of said closed pouch wherein said frangible seal divides said closed pouch into separated compartments;
(d) a liquid beverage confined to one of said separated compartments;
(e) another ingredient confined to a second separated compartment; and
(f) a fitment.

Abstract
A polymeric film, multiple-compartment, pouch having an internal frangible seal for confining a fluid and related beverage container with a re-closable fitment for storing and delivering two different flavored liquids or the like. The frangible seal of the clear plastic pouch will burst when sustained squeezed thus allowing the flavors to swirl and mix within the pouch.

16. A flexible multiple-compartment pouch comprising:
-
(a) a first sheet of polymeric film;
(b) a second sheet of polymeric film superimposed on said first sheet of polymeric film wherein said first and second sheets of polymeric film are sealed to each other directly or indirectly through a third intervening polymeric film thus defining a sealed perimeter forming a closed pouch;
(c) at least one frangible seal internal to the perimeter of said closed pouch wherein said frangible seal divides said closed pouch into separated compartments; and
(d) a fluid confined to at least one of said separated compartments wherein the seal strength of said sealed perimeter of said closed pouch is sufficient to withstand manual compression of the fluid confined to at least one of said separated compartments and wherein the seal strength of said frangible seal is insufficient to withstand manual compression of the fluid confined to at least one of said separated compartments thus allowing said fluid after sufficient sustained manual compression to commingle with the contents of at least one other separated compartment. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

26. In a flexible multiple-compartment pouch comprising heat sealed polymeric film with at least one frangible seal internal to the perimeter of said pouch wherein said frangible seal divides said pouch into separated compartments the specific improvement comprising:
- said frangible seal further comprises at least one force concentrating means for selectively exceeding seal strength of said frangible seal by experiencing a seal breaking force of from 1,500 grams per inch up to 10,000 grams per inch at a pressure increase within at least one of said separated compartments of from 0.5 psig to 10 psig.
