Refuse container assembly

Claim 1

A container assembly comprising: (a) an erectable, open-ended cylinder formed from a rectangular flat board of thin, flexible, synthetic plastic material that is rollable into a cylindrical form, said board being die cut to define detachable locking means to maintain this form which seeks to unroll; and (b) a collapsible plastic bag lining the cylinder and enclosing its bottom end, said bag having a length somewhat greater than that of the cylinder to define an upper margin that is folded over the rim of the cylinder to form a holding collar to maintain the bag in place, said locking means being constituted by a set of tabs projecting longitudinally from one end of the board and a corresponding set of transverse slots adjacent the opposite end of the board, each tab having a bendable cut-out flap which, when the tab is inserted in the corresponding slot, is caught in the slot as the cylinder seeks to unroll to prevent removal of the tab therefrom, said assembly having a storage mode in which said bag is in a collapsed state and said board is flat and free of protuberances, and a collection mode in which the board is rolled into a cylinder and is lined by the bag.
