Abstract
Abstract A collapsible trunk in which the walls of the lid and body are pivotally secured to the top and bottom panels respectively by a continuous flexible strip. The walls are secured to each other by rigid edge securing means in the form of angle irons. The trunk is knocked down by removing the corner angles and the angle irons that are held by the few bolts. The walls then pivot about the flexible strip to a planar position with their respective top or bottom panel.
