Abstract: A hamper bag is removably-mounted by a supporting base defined by a pair of opposing scissor-linkages. The hamper bag includes a pair of rods inserted through its upper lip, which rods are used to hold the hamper bag open on the supporting base by extending the rod-members over dowel-members interconnecting the upper portions of the pair of scissor-linkages, such that the rods are overhung relative to the dowel-members. The upper portions of the slats forming the scissor-linkages serve to prevent the removal of the sides and, therefore, the bag without first moving the rods away and up from the dowel-members to clear the dowel-members. The hamper bag may be carried separately or together with the collapsed supporting base.
