Collapsible receptacle for flexible beverage container

摘要

In combination, a liquid holding container having flexible walls is contained within a collapsible receptacle having rigid walls to prevent liquid from exiting the container when unwanted pressure is exerted on the container walls. The collapsible receptacle has an interior space to receive the liquid holding container when in an extended position, and is substantially flat in the collapsed position. The panels and bottom of the collapsible receptacle may be joined together with reversible hinges, or reversible biasing hinges to bias the receptacle to either an extended or collapsed position.
