Abstract
Abstract A paperboard container comprises an opened top receptacle adapted to contain foodstuffs therein and a separate cover telescopically disposed on the receptacle. The receptacle comprises a bottom panel, a pair of laterally spaced end panels, a back panel and a front panel hingedly connected to the bottom panel. A pair of lock flaps are hingedly connected to opposite ends of the front panel to each engage within a slot defined on a forward edge of a respective end panel. A slit, formed on the end panel, defines a lock tab adapted to bend outwardly to receive the lock flap thereunder when the front panel is moved to its closed position. The receptacle is adapted to be loaded with foodstuffs, such as asparagus, upon opening of the front panel which is thereafter closed for reception of the cover on the receptacle.
