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 curled bead which is received in a sealing groove in the lid. The container 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. Extending from the inner wall segment of the U-shaped groove in the lid is a frusto conical wall segment extending radially-inwardly and vertically-upwardly to a flat, annular, radially-inwardly extending surface which in turn terminates in a downwardly-extruding frusto conical surface so that a raised collecting basin is formed in the lid. The collecting basin provides a mechanism resisting lid sealing groove deformation when the lid is pierced for tint plug insertion while effectively providing an ingress-egress path for paint flow to prevent any potential for paint leakage during mixing of the paint in automatic shaker machines.
