ABSTRACT:
A collapsible, bulk shipping container that is made up of an inverted tray-type rectangular bottom and a pair of collapsible body elements, one end of each of which is telescopically received in the tray-type bottom. The collapsible body elements collectively form the body of the container and each is collapsible from a fully open position, in which they cooperate to form the container body and fill the tray-type bottom, into a collapsed condition in which the first lies against one side of the tray-type bottom, and the second lies in superimposed relationship on the first collapsible body element, each collapsible body element being secured to one side of the tray-type bottom. When the collapsible body elements have been collapsed, they can be folded over to lie in superimposed relationship above the tray-type bottom in a compact configuration for ease of the shipment or storage of the bulk shipping container. The tray-type bottom is preferably formed from a unitary blank of corrugated fiberboard, and each of the collapsible body elements is preferably formed from a sheet of corrugated fiberboard.
