Composite lid of container and method of attaching metal lid to plastic lid to form composite lid of container

Abstract

A composite lid of a cylindrical container includes an outer metal lid having an integral top wall and sidewall and an inner plastic lid having a top wall and sidewall fitted inside the outer metal lid such that a free end of the sidewall of the inner plastic lid extends beyond a free end of the sidewall of the outer metal lid. The composite lid can be fitted on a base having an integral bottom wall and sidewall such that the sidewall of the inner plastic lid frictionally engages the sidewall of the base. The outer metal lid can be formed by stamping sheet metal, the inner plastic lid can be formed by molding a polymer material and the base can be formed by molding a polymer material. The outer metal lid can be adhesively bonded or mechanically fitted to the inner plastic lid.
