Disposable collapsible drink mixing container

Abstract

A drink container has a liquid-tight film pouch which is collapsible into a substantially flat condition. Drink ingredients in a solid or condensed liquid state can be stored in or added to the pouch through an opening in an upper portion of the pouch. A cover with a liquid tight seal closes the opening. A dispense opening with a straw may be provided, or the beverage can be dispensed through the fill opening. The openings, straws and cover are located and contoured to conform with the desired substantially flat storage condition.
