Abstract
A canister including a lid and storage canister. The lid incorporates a gasket that is overmolded onto the lid during its manufacture. The gasket is exposed on both the upper and lower surfaces of the lid in order to provide a non-slip surface at the top portion of the lid and a sealing surface at the bottom of the lid for sealing a storage canister.
Claims18
A lid to cover a first canister comprising:
- a body and an integral gasket, the gasket comprising an uppermost portion, a lowermost portion, and a plurality of connectors;
- wherein the uppermost portion of the gasket and a central portion of the lid are horizontal in use and substantially coplanar;
- wherein the uppermost portion of the gasket and the central portion of the lid together form a substantially flat, upwardly-facing horizontal surface within an upper depression, upon which a lowermost part of a second canister is capable of resting, and the gasket is capable of providing a non-slip interface between the canister lid and the lowermost part of the second canister;
- wherein a lip is formed on the lid body and is configured to define the upper depression, the upper depression being sized and configured to receive the lowermost part of the second canister such that canister lid does not grip the second canister when the second canister is placed on the canister lid;
- wherein the lid body comprises an upper surface and a lower surface;
- wherein the lid body has a plurality of first openings formed between the upper surface and the lower surface through which the plurality of connectors extend;
- wherein the plurality of connectors are disposed between the uppermost portion and the lowermost portion of the gasket;
- wherein the plurality of connectors connect the uppermost portion and the lowermost portion of the gasket through the plurality of openings formed in the lid;
- and
- wherein a lower surface of the lowermost portion of the gasket engages an uppermost edge of the first canister.

A method of forming a lid for a storage canister comprising:
- positioning a lid into a mold, the lid comprising a plurality of openings between an upper and lower surface of the lid;
- and
- introducing a gasket material into the mold such that the gasket material forms a gasket having a lower portion with a lower surface and an upper portion with an upper surface, the gasket having a plurality of connectors disposed between the upper portion and the lower portion, wherein the plurality of connectors serve to connect the upper portion to the lower portion through the plurality of openings formed in the lid such that the upper portion and the lower portion of the gasket are held in position by the plurality of connectors,
- wherein the lid mold used to form the lid is configured such that the upper surface of the gasket and a central portion of the lid are horizontal in use and substantially coplanar within an upper depression of the lid;
- and
- wherein the lid mold used to form the lid is configured such that the gasket is exposed on an upper and lower portion of the molded lid.
