Double lock lid with flexible tab

A lid for a container, said container having an peripheral side wall with an upper rim, said rim including an upper peripheral, annular outwardly extending locking flange and a lower peripheral, annular outwardly extending locking flange, each of the upper peripheral annular outwardly extending locking flange and the lower peripheral annular outwardly extending locking flange, independently, having an underside for locking engagement with the container lid, the lid comprising:

• a central portion;
• and
• a peripheral downwardly extending annular skirt configured to overlie and engage at least a portion of the container wall;
• wherein:
• the downwardly extending annular skirt includes an annular groove dividing said skirt into a skirt upper portion, and a skirt lower portion;
• the skirt upper portion includes an inwardly extending upper lid locking flange that projects inwardly from an inner surface of the skirt upper portion and extends continuously about an inner circumference of the upper skirt portion, the upper lid locking flange configured for engaging the underside of the upper peripheral annular outwardly extending locking flange of the container;
• the skirt lower portion includes a plurality of inwardly disposed flexible locking tabs disposed in spaced apart relationship about an inner circumference defined by an inner surface of the skirt lower portion, wherein each one of the plurality of inwardly disposed flexible locking tabs, independently, extends inwardly from the inner surface of the skirt lower portion and is adapted to engage a portion of the container wall when said lid is positioned on said container;
• each one of the plurality of inwardly disposed flexible locking tabs, independently, is moveable between at least:
• (i) a first position wherein each one of the plurality of flexible locking tabs, independently, extends downwardly and away from the inner surface of the skirt lower portion, and (ii) a second position wherein each one of the plurality of flexible locking tabs, independently, extends upwardly and is disposed adjacent to the inner surface of the lower skirt portion;
• and
• while the lid is positioned on said container such that the container is disposed in a closed condition, the inwardly extending upper lid locking flange, the plurality of inwardly disposed flexible locking tabs, the upper peripheral annular outwardly extending locking flange, and the lower peripheral annular outwardly extending locking flange are co-operatively configured such that:
• (i) a first lid-locking configuration is established by engagement between the inwardly extending upper lid locking flange and the underside of the upper peripheral annular outwardly extending locking flange, the first lid-locking configuration extending continuously about an engagement interface defined between the skirt upper portion and the container;
• and
• (ii) a second lid-locking configuration is established by engagement between each one of the plurality of flexible locking tabs, independently, and the underside of the lower peripheral annular outwardly extending locking flange such that a plurality of discrete engagement interfaces are established between the skirt lower portion and the container;
• and
• in response to application of an upwards force to the lid, relative to the container, while the lid is disposed on the container, removal of the lid from the container is resisted by at least:
• (a) at least some of the plurality of flexible locking tabs abutting the underside of the lower peripheral annular outwardly extending locking flange, and (b) the inwardly extending upper lid locking flange abutting and the underside of the upper peripheral annular outwardly extending locking flange.
