Abstract
A collapsible carton comprises opposing front and back panels, opposing top and bottom panels generally bridging said opposing front and back panels, a first pair of accordion panels connecting said front panel to said bottom panel, and a second pair of accordion panels connecting said back panel to said bottom panel. The carton further includes a plurality of side closure flaps extending from opposing ends of the top and bottom panels and the front and back panels. When the carton is in open-sided form and after a compressible product is loaded into the carton through one of the open sides, the carton is collapsed in response to moving the top and bottom panels toward each other so as to cause the first and second pairs of accordion panels to spread outward in accordion-like fashion into overlapping relationship.
