Lid having a circumferential rim with a plurality of annular ribs

A lid for a container comprising:

• a disk shaped member including a circumferential rim extending about a periphery, the circumferential rim of the disk shaped member comprising a raised annular inner side wall, a raised annular outer side wall, wherein the raised annular outer side wall extends around the raised annular inner side wall and is generally parallel to and opposite the raised annular inner side wall, the raised annular outer side wall and raised annular inner side wall being interconnected by an annular top wall, wherein the annular top wall is generally perpendicular to the raised annular outer side wall and raised annular inner side wall, wherein the raised annular inner side wall includes first and second annular ribs disposed in continuous rings parallel to one another;
• the first annular rib is positioned proximate to a top portion of the raised annular inner side wall, relative to the second annular rib which is positioned below the first annular rib;
• the first and second annular ribs each include a generally, convex profile relative to an inner surface of the container, and form an annular rib channel therebetween, the rib channel of the raised annular inner side wall is intermediate to the first and second annular ribs and positioned at a bottom of the first annular rib and a top of the second annular rib, the rib channel is positioned for retaining liquid that seeps beyond the second annular rib prior to contacting the first annular rib when tilting the container to allow its contents to escape;
• the first and second annular ribs of the raised annular inner side wall thereby form a primary sealing surface against a flat wall of the container to which the lid may be attached for substantially preventing leakage, and a third rib formed in the raised annular outer side wall opposite to the raised annular inner side wall and the third rib positioned higher than the second annular rib when the lid has the annular top wall in an uppermost orientation, wherein the third rib is formed by an indentation and provides a gripping area for securing the lid to a brim of the container and the third rib formed in the outer side wall opposite the first and second annular ribs of the inner wall.

A container closure for a container comprising:

• a disk shaped member including a circumferential rim extending about a periphery, the circumferential rim of the disk shaped member comprising a raised annular inner side wall, a raised annular outer side wall, wherein the outer side wall extends around the raised annular inner side wall and is generally parallel to and opposite the raised annular inner side wall, the raised annular outer side wall and raised annular inner side wall being interconnected by an annular top wall, wherein the annular top wall is generally perpendicular to the raised annular outer side wall and raised annular inner side wall and wherein the raised annular outer side wall includes an indentation forming a first rib extending annularly along the raised annular outer side wall, and wherein the first rib includes a convex profile relative to a flat outer wall of the container, the first rib is formed intermediate to a rib element, the rib element having a flared end, positioned distal to the top wall and a second annular rib formed in the raised annular inner side wall opposite the raised annular outer side wall, the container closure capable of securing a brim and flat wall of the container between the first rib and the second annular rib of the raised annular inner side wall, a third annular rib formed in the raised annular inner side wall below the second annular rib opposite to the raised annular outer side wall and the third annular rib positioned lower than the first annular rib and the second and third annular ribs configured to seal against the flat outer wall of the container.
