Abstract
Abstract A collapsible carton and the single blank from which same is prepared are provided, said carton and blank comprising foldably connected outer wall panels and further characterized by an inner and outer bottom panel, each of which is foldably connected to an opposed outer wall panel, and a pair of opposed inner wall panels which are foldably connected to said outer bottom panel. The outer bottom panel, to which the internal side panels are attached, is maintained in a supportive position by the restraining force exerted against the vertical edges of the inner wall panels by the outer side wall panels in the assembled position. The inner bottom panel rests atop the first bottom panel and is supported thereby. The carton may be further provided with ventilation and handle apertures, cover panels, and a variety of other modifications.
