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 is rigidized by a single protrusion in the form of a groove to prevent vertical collapse of the container. The design disclosed permits easy modification of the container for serially stacking thereof.
