ABSTRACT:
A rectangular storage container having a pivotal cover and a body either of which having semicylindrical blocks or rods mounted to their structure providing fulcra in opening the cover. In a preferred embodiment, the storage container includes a square cover and a square body. The square cover comprises a pair of pivots on an inside surface and symmetrically positioned on opposite peripheral sides, a block on the inside surface and centrally positioned at a first end thereof, a chamfer at the first end, and a notch at an opposite second end thereof. The square body comprises an upper peripheral rim and a flange. The pair of pivots and the block rest on the upper peripheral rim of the body while the peripheral sides of the cover rest on the flange of the body. The pair of pivots serve as fulcra and thereby the cover can be opened by applying a force on the first end with the chamfer of the cover being flush with the flange of the body.
