Abstract
A lid for a plastic container, which container is particularly useful for containing paint, includes a sealing flange which engages the inner surface of a rim defining the opening of the container. The sealing flange is held in engagement with the rim by a plurality of locking tabs which are integral with the lid and fit beneath an inwardly projecting lip on the flange. The flange has a generally convex configuration while the rim has a concave configuration so that the lid is prevented from moving axially out of or into the container once it is locked in place by the tabs.
Claims15
A lid for closing an opening in a container wherein the lid engages an inner wall of the container, the lid comprising:
- a central portion for substantially covering the opening, and
- a bifucated securing portion integral with and extending from the central portion, said bifucated portion comprising a sealing flange, a web connecting the sealing flange to the central portion and locking tab means diverging from the web wherein the sealing flange extends beyond the locking tab means and the locking tab means seats behind the sealing flange for holding the sealing flange in abutment with the inner wall of the container.
In combination, a lid and a container having an opening which is sealed by the lid, the combination comprising:
- a rim on the container adjacent to the opening, the rim having an inwardly facing sealing surface;
- the lid having a unitary structure including a central portion substantially closing the opening and a bifucated securing portion, the bifucated securing portion having a web portion, a sealing flange and locking tab means, wherein the web portion connects the sealing flange to the central portion;
- wherein the locking tab means diverges radially from the central portion and laterally from the web portion to form the bifucated securing portion and seats behind the sealing flange to lock the sealing flange in place against the rim, and wherein the sealing flange includes an outwardly facing sealing surface which complements the inwardly facing sealing surface of the rim.
A lid made of plastic for closing an opening in a container wherein the lid engages an inner wall of the container, the lid comprising:
- a central portion for substantially covering the opening;
- a bifucated securing portion integral with and extending from the central portion to the inner wall of the container with which the lid is used;
- said bifucated securing portion including sealing flange means extending generally normally to the central portion when the lid is in place to close the container and having a sealing surface for engagement with the inner wall of the container, web means for connecting the sealing flange to the central portion and locking tab means projecting over the web means and seating behind the sealing flange to secure the sealing flange in abutment with the inner wall of the container.
