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.

A container and lid combination in which: the container has a sidewall defining a rim, an opening circumscribed by the rim, and an inner container surface adjacent to the rim; the lid is adapted to be located about the container rim, the lid including a dished lid portion which extends into the opening in the container when the lid is located about the container rim; a flexible skirt is injection molded of an elastomeric material with one of the inner container surface and the dished lid portion, the skirt being so shaped that as the lid is located about the container rim the skirt is deflected relative to the one of the inner container surface and the dished lip portion by the other one of the inner container surface and the dished lid portion to an operative position in which the skirt is biased because of the elasticity of the elastomeric material to press against the other one of the inner container surface and the dished portion in sealing engagement thereby sealing the interior of the container; and securing means attached to at least one of the container and the lid for releasably securing the lid to the container when the lid is located about the container rim.
