Abstract
A reclosable cup lid thermoformed from a polymeric material includes a domed member and a closure panel. The thermoformed domed member is provided with a sidewall and a top wall, the top wall having upper and lower surfaces and a drinking aperture at a periphery of the top wall. The top wall further defines a pair of engagement tracks depending from the lower surface of the top wall and also defines a post aperture disposed inwardly with respect to the drinking aperture. The closure panel has opposed engagement edges, an upper surface provided with a post projecting upwardly therefrom, and a drinking aperture sealing area. As assembled, the domed member and closure panel are configured such that the opposed engagement edges of the closure panel are slidingly mounted in the engagement tracks for generally radial displacement.
