Abstract: A method for fabricating a lid for attachment to a vessel having an open top surrounded by a peripheral edge portion, includes injection molding from a molten plastic material a first shot structure defining a web portion, a peripheral portion surrounding the web portion; in a second shot procedure, over-molding an elastomeric material different from said plastic material onto the first short structure to form a seal structure portion integrated with the lid portion to form a unitary lid-seal structure, wherein the seal structure portion is permanently adhered to the peripheral portion of the first shot structure, and wherein the seal structure portion is configured to provide an air-tight seal between the lid and a sealing surface portion of the peripheral edge of the vessel when the lid is attached to the vessel.

Abstract: An exemplary embodiment of a vessel-lid combination includes a ceramic or glass vessel having an open top surrounded by a peripheral edge, a lid fabricated of a plastic material, and a seal structure. The lid is configured to attach to the open top by means of a latch or set of latches integrated with the lid, and the seal structure is configured to provide an air-tight seal between the lid and the peripheral edge of the vessel when the lid is attached to the vessel.

Abstract: An exemplary embodiment of a vessel-lid combination includes a glass, ceramic or metal vessel having an open top surrounded by a peripheral edge, a lid fabricated of a plastic material, and a seal structure integrated with the lid to form a unitary structure. The lid is configured to attach to the open top by means of a latch or set of latches integrated with the lid, and the seal structure is configured to provide an air-tight seal between the lid and the peripheral edge of the vessel when the lid is attached to the vessel. In one exemplary embodiment, the vessel is a container fabricated of a glass suitable for baking or oven heating applications.

Abstract: A system for aiding the visual matching of containers having diverse openings with matching lids includes affixing, such as by molding or embossing, geometric planar patterns on the bottom walls of a plurality of rectangular containers having different sized openings and affixing the same geometric patterns to the top wall of the matching lids.

Abstract: A method of merchandising a modular home storage container system includes providing a plurality of individual groups of containers adapted for use on standardized shelving. Each container has side walls extending upwardly from a bottom wall to an open top and a removable lid. The containers, in each group, have a uniform length which correlates with one of the shelving depths, a uniform width to provide a uniform footprint size to accommodate the use of a single size lid and a plurality of different heights to allow a consumer to optimize the use of the available shelf height space. The heights of the containers are graduated so that the overall height of two stacked shorter containers will approximate the height of a taller container. Preferably a chart correlating the lengths of the individual groups of containers with standard shelving depths is available at the display site.
