ABSTRACT:
A collapsible container is fashioned from a unitary blank of paperboard. The container is in the general form of a lower and truncated tray having a top closure lid hingedly secured to the top of the rear wall of the tray. After glueing of the lower tray, the tray is collapsed by bowing its side walls inwardly so that the entire tray may assume a substantially flattened configuration. The flattened container may then be shipped to a retail establishment, such as a fast food outlet, for subsequent set up or erection by merely unfolding the tray and pushing its sidewalls outwardly. In order to overcome the natural tendency of the sidewalls to resume their inwardly bowed configuration, having been stored in this shape for, typically, a substantial length of time, the sidewalls are provided with a novel latching slit and corner tab configuration which maintains the sidewalls in their desired substantially planar form. The container also exhibits a novel top latching arrangement wherein a latching tongue may be inserted into a complementary latching recess in either of two different ways.
