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.
