ABSTRACT:
A lid retainer is provided for a "paint can" type container having a lid that is secured to the top wall thereof by multi-friction fit. The lid retainer is composed of a high tensile strength, impact resistant polymer material having limited flexible and defines a circular body section with a circular lid retainer flange and a circular locking flange projection downwardly from respective inner and outer radial extents of the circular body section. The locking flange has a radially inwardly extending locking projection having a downwardly and radially inwardly facing can surface disposed for camming engagement with the circular bead that interconnects the side and top walls of the container and induces yielding of the retainer flange as the locking projection passes over the circular bead. The retainer flange is positioned for circular contact with the central panel of the lid at a location radially inwardly of the friction seal for the lid of the container and radially inwardly of the central opening of the top wall, thereby providing sufficient mechanical advantage to effectively resist pressure induced unseating of the lid from the top wall.
