ABSTRACT:
A panel-like lid is secured to a receptacle by a pintle for pivotal movement between a closed position and an open position about an axis whereby the lid remains horizontal at all times. In the closed position, a continuous groove in the underside of the lid matingly receives a bead upstanding from the upper edge of the sidewall of the receptacle. A compression spring encircling the pintle normally urges the lid downwardly against the receptacle. In response to movement from the closed position toward the open position, the lid is cammed upwardly to disengage the groove from the bead.
