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.

The combination of a ringless metal container with a removable, resealable lid for sealing liquid contents therein comprising: a) a container having a cylindrical body portion, a mouth opening formed as a curled bead and a rim portion extending from said mouth opening to said body portion, said opening smaller in diameter than said body portion so that said rim portion tapers radially-inwardly therebetween, stiffening means at the juncture of said rim portion with said body portion for strengthening said rim portion, said curled bead having a generally vertical, inner annular wall section extending at its top into said curled bead and at its bottom into said rim portion; and b) a lid having a generally circular configuration with an annular sealing groove extending about its periphery, said sealing groove defined by annular, vertically extending inner and outer sealing wall segments with a bight wall segment longitudinally extending therebetween; said outer sealing wall segment forming an annular outer line contact with said curled bead and said inner sealing wall segment in flat area contact with said curled bead\s vertical wall section to compress said curled bead; said inner sealing wall segment terminating in an annular, frusto-conical drip wall segment tapering radially inwardly and vertically upwardly at an ingress angle approximating that at which said rim portion tapers radially inwardly and vertically-upwardly towards said bight wall segment, said vertical inner sealing wall segment intersecting said drip wall segment in an annular groove approximately at the intersection of said rim portion with said bottom of said container\s inner annular wall section when said lid is assembled to said body portion so that said rim portion and said drip wall segment cooperate to direct container contents radially-inwardly and upwardly past said sealing groove upon can shaking thus avoiding content leakage past said curled bead; said frusto-conical drip wall segment terminating at an annular, radially-inwardly extending collecting wall segment, said collecting wall segment terminating at a stiffening frusto-conical wall segment tapering radially inwardly and vertically-downwardly at an egress angle whereby paint splashed against said lid during can shaking is directed back into the container; said frusto-conical drip wall segment, said collecting wall segment and said stiffening wall segment forming a collecting basin for container contents splashed against said lid during shaking whereby said contents do not drip into said sealing groove nor on the outside of said body portion after said container is shaken and said lid is removed.
