ABSTRACT:
A tamper-evident, reclosable, integral rigid plastic lid for use on a container having an upper circular wall provides a double seal for the container contents until opened by a user and a single seal thereafter. The lid has a circular base, with a recess therein and a rupturable planar member extending across the recess, and a hinged closure member secured to a platform which completely covers the recess. The platform is in the shape of a segment of the circle formed by the circular base with a downwardly extending face provided along a chord of the circle which, with an arcuate raised rim about the circular base forms the bounds of the recess.
