ABSTRACT:
An all-plastic, hinged, tamper-evidencing closure includes an upper closure surface or top with a hinge formed therein. The hinge may be a straight line, or curved or arcuate so as to provide a snap-action for opening and closing. The closure includes a peripherally depending skirt which has structure for removably retaining the closure on a container, such as a snap head or threads. Additionally, the skirt includes tamper-evidencing structure. The closure top surface may be planar, concave or convex, or it may be initially planar, but when subject to vacuum or pressure it becomes concave or convex, respectively. This latter feature provide a visual indicator that the vacuum seal or pressure seal of the container is intact.
