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 rim section is rigidized by a single protrusion in the form of a stiffening groove to prevent vertical collapse of the container. The lid has an inverted U-shaped groove sealingly engaging the container's bead. The outer wall of the U-shaped groove has a plurality of long length and short length sections. The long length sections are designed to contact the stiffening groove in the event inadvertent container deforming forces are applied to seal the lid while the short length sections of the lid assure pry points for lid removal.
