A receptacle in which a collapsible fluid-holding container is disposed within an outer rigid container. The collapsible container comprises a flexible bag and a mouthpiece that is joined to the mouth of the rigid container. A valve in the outer container at a region distal from the mouth vents the region between the containers to enable the collapsible container to be filled with liquid. The valve also admits air between the containers to enable the inner container to collapse as fluid is dispensed. A pair of feet protrude laterally from one side of the receptacle to raise the bottom of the receptacle when it is horizontally disposed in a fluid-dispensing position. A method is disclosed for evacuating the outer container to facilitate the expansion of a collapsed flexible container.

A receptacle for pressurized carbonated liquid, said receptacle comprising an outer container of substantially fixed shape formed with a mouth at one end thereof defining an opening into said outer container, an inner container for holding a fluid, said inner container being disposed within said outer container and being formed with a mouthpiece of substantially fixed shape defining an opening into said inner container, at least a portion of the mouthpiece of said inner container being disposed at the mouth of said outer container, at least a major portion of said inner container being collapsible, venting means located along said outer container at a region distal from said mouth for admitting air between said inner and outer containers to permit collapse of said inner container when fluid is poured therefrom, said venting means comprising at least one aperture in the bottom of said outer container, and means for sealing said venting means when said carbonated liquid causes the pressure inside said inner and outer containers to exceed the pressure outside said outer container, thereby preventing extrusion of said inner container through said venting means when pressure builds up in said inner container, said means for sealing comprising a thickened wall on that end of said inner container opposite said mouthpiece, the remaining portion of said inner container other than aid thickened wall having a substantially uniform thickness, said thickened wall being sufficiently thick that it prevents extrusion of said inner container through said at least one aperture when said carbonated liquid causes the pressure inside said inner and outer containers to exceed the pressure outside said outer container.
