Abstract:
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 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 wherein the 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 wherein the 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 wherein the 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.
