A unitary nestable reclosable container is formed from a thin-walled clear flexible plastic or the like and includes a box-like base forming a receptacle for screws, bolts, etc. A lid is integrally joined to the base by a hinge and includes a peripheral groove having walls releasably engaging substantially planar side walls of the base for providing a sturdy closure. The peripheral groove further provides a wall which releasably locks with an upper portion of the base end wall providing a specially designed reversed taper spaced from a lower end wall portion by a restraining shelf. Each side juncture between the lid and base is substantially within a plane provided by the side wall while a label placed across such juncture forms a reliable seal. The side walls and end walls have specially designed pre-established angular orientations with respect to the bottom portion so that a plurality of similarly constructed containers may be nested in a stack while further allowing each individual container to be placed in an upstanding position supported by the end wall and integral hinge.
A reclosable container of thin flexible thermoformed plastic material comprising a rectangular container base having a generally flat bottom and planar sidewalls and front and rear end walls joining the sidewalls, a lid integrally hinged to the rear end wall and movable between open and closed positions to provide a top portion for closing and strengthening the container base, the lid having a peripheral generally V-shaped groove extending downwardly from the plane of the lid and defined by inner and outer walls joined along the bottom of the groove providing a lateral stiffening member for the lid and the container base, the outer groove wall being shaped and engaging the top inner portions of the sidewalls and end walls when the lid is in its closed position to support them against inward flexing and bending and provide a sturdy container construction, the lid having a horizontal flange in the plane of the lid overlying the top edges of the sidewalls without extending outward substantially beyond the plane of the sidewalls providing a junction with the sidewalls substantially within the plane of the sidewalls to permit a label to be applied to the lid and at least one sidewall without substantial separation of the label from the plane of the sidewall to lockingly seal the container.
