Abstract
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.
