Abstract: A collapsible receptacle, such as a beverage cup, that is reconfigurable between expanded and collapsed configurations with an inner sleeve with first and second opposed major walls divided by opposed fold lines, an outer sleeve with first and second opposed major walls divided by opposed fold lines, and a liner retained by the inner and outer sleeves. The receptacle is retained in an expanded configuration when the opposed fold lines of the inner and outer sleeves are not aligned, and the receptacle can be collapsed when the opposed fold lines are aligned. A lid can be removably retained by a retaining ring. The opposed fold lines of the inner and outer sleeves can be disposed in groups, such as groups of two fold lines, so that the sleeves have opposed minor walls. The major walls can taper in thickness from their mid-portions to the opposed fold lines.
