1. A flexible multiple-compartment container comprising (1) a single sheet of polymeric film or multi-sheet of polymeric film and (2) at least one frangible seal whereinthe polymeric film is single layer or multilayer;
- the single sheet is folded back on itself and sealed along essentially the superimposed edges directly or indirectly through a third intervening polymeric film thereby defining a first sealed perimeter and forming a closed pouch;
or whereinthe multi-sheet comprises at least a first sheet of polymeric film and a second sheet of polymeric film;
the second sheet is superimposed on the first sheet;
the first sheet and the second sheet are sealed to each other directly or indirectly through a third intervening polymeric film thereby defining a second sealed perimeter and forming the closed pouch; and
whereinthe frangible seal is formed by heat-sealing together the inner surface of the polymeric film;
the frangible seal is internal to the first sealed perimeter or the second sealed perimeter and the frangible seal divides the closed pouch into separated compartments comprising a first compartment and a second compartment;
the frangible seal comprises a curved portion and variable width that follows the path of the curved portion with a maximum width near the segment of the curved portion having the smallest radius of curvature;
the first compartment comprises or confines a fluid;
the second compartment comprises or confines another ingredient; and
whereinthe first sealed perimeter or the second sealed perimeter has a seal strength sufficient to withstand manual compression of the fluid and the seal strength of the frangible seal is insufficient to withstand manual compression of the fluid, thus allowing the fluid of the first compartment to commingle with the other ingredient of the second compartment.

Abstract
A polymeric film, multiple-compartment container having an internal frangible seal comprising a curved portion and variable width with a maximum width near the portion of the curve having the smallest radius of curvature, 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 container will burst when sustained squeezed thus allowing the components in the container to mix within the container.

18. A flexible multiple-compartment pouch comprising (1) a heat-sealable single sheet of polymeric film or multi-sheet of polymeric film and (2) at least one frangible seal wherein
the polymeric film is single layer or multilayer; -
the single sheet is folded back on itself and sealed along essentially the superimposed edges directly or indirectly through a third intervening polymeric film thereby defining a first sealed perimeter and forming a closed pouch;
or whereinthe multi-sheet comprises at least a first sheet of polymeric film and a second sheet of polymeric film; the second sheet is superimposed on the first sheet; the first sheet and the second sheet are sealed to each other directly or indirectly through a third intervening polymeric film thereby defining a second sealed perimeter and forming the closed pouch; and
whereinthe frangible seal is formed by heat-sealing together the inner surface of the polymeric film; the frangible seal is internal to the first sealed perimeter or the second sealed perimeter and the frangible seal divides the closed pouch into a first compartment and a second compartment; and the frangible seal comprises a curved portion and variable width that follows the path of the curved portion with a maximum width near the segment of the curved portion having the smallest radius of curvature thereby providing 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. - View Dependent Claims (19, 20)
