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.

Claims29

Dependent claims

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 generally rectangular sealed perimeter having a first end and a second end and two opposed sides, forming a closed pouch;
(c) at least one smooth curve frangible seal internal to the sealed perimeter and said at least one smooth curve frangible seal divides said closed pouch into separated compartments comprising a first compartment and a second compartment;
(d) the first compartment comprises or confines a liquid beverage;
(e) the second compartment comprises or confines another ingredient;
and
(f) a fitment in said first end;
wherein the second end is the end opposing the fitment and the at least one smooth curve seal extends from said first end to one of said opposed sides.

5 more elements

A flexible multiple-compartment pouch comprising a first sheet of polymeric film sealed to a second sheet of polymeric film with at least one smooth curve frangible seal produced by heat sealing or zone coating internal to the perimeter of said pouch wherein said pouch is a stand-up pouch;

said at least one smooth curve frangible seal divides said pouch into separated compartments comprising a first compartment and a second compartment and experiences seal breaking force of from 400 grams per inch up to 6,000 grams per inch at a pressure increase of from 0.5 psig to 5 psig within the first or second compartment;
the stand-up pouch is generally rectangular having a bottom, an opposing end to the bottom, and opposed sides to the bottom and the opposing end;
and the at least one smooth curve frangible seal extends from the opposing end to one of said opposed sides.

said at least one smooth curve frangible seal divides said pouch into separated compartments comprising a first compartment and a second compartment and comprises at least one force concentrating means for selectively exceeding seal strength of said at least one smooth curve 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 of from 0.5 psig to 10 psig within the first or second compartment;
the stand-up pouch is generally rectangular having a bottom, an opposing end to the bottom, and opposed sides to the bottom and the opposing end;
and the at least one smooth curve frangible seal extends from the opposing end to one of said opposed sides.
