ABSTRACT:
A two-piece, snap-action closure includes a body and a separate lid. A biasing member is provided on the body to engage the rear portion of the lid to bias the lid to the full closed position or to the full open position from a bistable over center point. In a preferred embodiment, the biasing member is a cantilevered tab. In another embodiment the biasing member is a resiliently flexible member that presents a convex configuration toward the lid in the closed position. In one embodiment, the lid is pivotally mounted to the body with pivot members having oppositely facing flat sides which are received in rectangular receiving apertures. In another embodiment, the pivot members are cylindrical and are received in semi-cylindrical receiving apertures. In a preferred form of the closure, an angled cam surface is provided on the body to guide each pivot member into the receiving apertures.
