A collapsible beverage container has a plurality of co-axially oriented, concentric cylindrical wall sections of progressively different diameters. The wall sections are extendable from a collapsed position wherein the wall sections substantially completely overlap in an axial direction to an extended position wherein the wall sections only partially overlap in an axial direction. The collapsible beverage container includes one or more elastomeric gaskets between adjacent cylindrical wall sections, each gasket providing a liquid-tight seal along the entire extension of the adjacent cylindrical wall sections between the extended and collapsed positions. |
