Abstract
An especially configured, ringless, container-lid, design is disclosed having improved sealing characteristics applicable to paint containers for the consuming public. The rim portion of the container is provided with a tapered, especially shaped wall section terminating in a circular bead which is received in a sealing groove in the lid. The wall section flexes to maintain the seal established between the lid and the bead while sufficiently rigidized to prevent collapse of the container's sidewall. The design disclosed permits easy modification of the container for serially stacking thereof.
