ABSTRACT:
The invention relates to a container and lid combination in which a flexible skirt is injection molded with either the container or lid to provide the combination with a seal. The skirt extends either radially inwardly from an inner container surface or radially outwardly from the underside of the lid, and is so shaped that as the lid is located about the container rim the skirt is deflected to a position in which it is biased because of the elasticity of the elastomeric material from which it is constructed to press against the inner container surface or underside of the lid in sealing engagment. In a preferred embodiment a circumferential bead is molded to one of the inner container surface and underside of the lid, and co-operates with the skirt to releasably secure the lid to the container.
