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.
