and a brim lock in the annular outer side wall for fastening the lid to the container; a plurality of dimples inverted along the annular outer side wall, wherein the plurality of dimples of the annular outer side wall project into the channel from the outer surface of the annular outer side wall and configured to be non-inverted dimples when the lid is secured onto the container. ## Claims ### Claim 1 A lid for a container comprising: a closure having a disk shape and a circumferential rim extending about a periphery of the closure; the circumferential rim further comprising an annular inner side wall, an annular outer side wall, wherein the outer side wall extends around the inner side wall and is opposite to the inner side wall, the outer side wall and inner side wall being interconnected by an annular top wall, the annular top wall interconnecting the outer side wall to the inner side wall, wherein the combination of the annular inner side wall, the annular outer side wall and the annular top wall define a channel; and a brim lock in the annular outer side wall for fastening the lid to the container; a plurality of dimples inverted along the annular outer side wall, wherein the plurality of dimples of the annular outer side wall project into the channel from the outer surface of the annular outer side wall and configured to be non-inverted dimples when the lid is secured onto the container. ### Claim 2 (depends on 1) The lid according to claim 1, wherein the inner side wall comprises at least one annular rib including a generally convex profile relative to an inner surface of an inside wall of the container, the at least one annular rib disposed along the annular inner side wall for providing a sealing surface and leakage prevention. ### Claim 3 (depends on 2) The lid according to claim 2, wherein the annular inner side wall includes first and second annular ribs disposed in continuous rings parallel to one another for providing a sealing surface and leakage prevention; wherein the first annular rib is positioned proximate to the top wall and on a top portion of the 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 an inside wall of the container, and form an annular rib channel therebetween, the rib channel of the 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. ### Claim 4 (depends on 3) The lid according to claim 3, wherein the rib channel is positioned for retaining liquid that seeps beyond the second annular rib prior to contacting the first annular rib; the first and second annular ribs of the inner side wall thereby form a secondary and primary sealing surface respectively for preventing leakage, with the rib channel therebetween forming a reservoir to retain liquid that seeps beyond the second annular rib prior to contacting the first annular rib. ### Claim 5 (depends on 1) The lid according to claim 1, wherein the inverted dimples project inwards and are within the outer surface of the annular outer side wall. ### Claim 6 (depends on 1) The lid according to claim 1, wherein the dimples project outwards beyond the outer surface of the annular outer side wall to assume a raised position pursuant to the application of a force on the plurality of inverted dimples when the lid is seated to the rim of the container. ### Claim 7 (depends on 1) The lid according to claim 1, wherein the raised dimples project beyond the outer surface of the annular outer side wall and can be perceived tangibly. ### Claim 8 (depends on 1) The lid according to claim 1, wherein the lid is fabricated using a mold configured for female tooling. ### Claim 9 (depends on 1) The lid according to claim 1, wherein the annular outer side wall includes one of the plurality of dimples positioned in each quadrant of the lid. ### Claim 10 A lid for a container comprising: a closure having a disk shape and a circumferential rim extending about a periphery of the closure; the circumferential rim further comprising a raised annular inner side wall, a raised annular outer side wall, wherein the outer side wall extends around the inner side wall and is opposite to the inner side wall, the outer side wall and inner side wall being interconnected by an annular top wall, the annular top wall interconnecting the outer side wall to the inner side wall, wherein the combination of the raised annular inner side wall, the raised outer side wall and the annular top wall define a channel; a brim lock in the annular outer side wall for fastening the lid to the container; and a plurality of dimples recessed along the annular outer side wall; wherein the plurality of dimples project away from the channel and are configured to project beyond an outer surface of the annular outer side wall when the lid is secured onto the container. ### Claim 11 (depends on 9) The lid according to claim 9, wherein the inner side wall comprises at least one annular rib including a generally convex profile relative to an inner surface of an inside wall of the container, the at least one annular rib disposed along the raised annular inner side wall for providing a sealing surface and leakage prevention. ### Claim 12 (depends on 10) The lid according to claim 10, wherein the annular inner side wall includes first and second annular ribs disposed in continuous rings parallel to one another for providing a sealing surface and leakage prevention; wherein the first annular rib is positioned proximate to the top wall and on a top portion of the inner side wall, relative to the second annular rib which is positioned below the first annular rib; each of the first and second annular ribs includes a generally convex profile relative to an inner surface of an inside wall of the container, and form an annular rib channel therebetween, the rib channel of the 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. ### Claim 13 (depends on 11) The lid according to claim 11, wherein the rib channel is positioned for retaining liquid that seeps beyond the second annular rib prior to contacting the first annular rib; the first and second annular ribs of the inner side wall thereby form a secondary and primary sealing surface respectively for preventing leakage, with the rib channel therebetween forming a reservoir to retain liquid that seeps beyond the second annular rib prior to contacting the first annular rib. ### Claim 14 (depends on 9) The lid according to claim 9, wherein the plurality of dimples project outwards and are recessed within the outer surface of the annular outer side wall. ### Claim 15 (depends on 9) The lid according to claim 9, wherein the plurality of dimples project outwards beyond the outer surface of the annular outer side wall to assume a raised position pursuant to the application of a force on the plurality of recessed dimples when the lid is seated to the rim of the container. ### Claim 16 (depends on 9) The lid according to claim 9, wherein the plurality of dimples project outwards beyond the annular outer side wall when the lid is secured onto the rim of the container. ### Claim 17 (depends on 15) The lid according to claim 15, wherein the raised dimples project beyond the outer surface of the annular outer side wall and can be perceived tangibly. ### Claim 18 (depends on 9) The lid according to claim 9, wherein the lid is fabricated using a mold configured for female tooling. ### Claim 19 (depends on 9) The lid according to claim 9, wherein the annular outer side wall includes one of the plurality of dimples positioned in each quadrant of the lid.
