Abstract: In one embodiment, a lid structure with latches is configured for sealing use with container vessels of different materials having differing manufacturing dimensional tolerances, such plastic vessels and glass vessels. Another feature of a lid and vessel combination is the provision of a lid receptacle feature, configured to capture the base of a vessel in a stacking arrangement, without utilization of special features on the vessel base. A method of merchandising lids and vessels is described, wherein a lid is provided for separate purchase, a plurality of vessels of different materials is provided for separate purchase which are configured to match to the lid.

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 storage system including, in an exemplary embodiment, a unitary open-topped container, and an air-tight lid system, suitable for storage of food items. The lid system includes a plastic lid including a cover portion and a plurality of lid latches connected to the lid cover portion by living hinges, and a seal gasket fitted into an inner seal channel formed in a lid peripheral region. The latches are configured for movement between extended positions in which the lid is removable from the container, and a latching position in which latch features engage a peripheral edge of the container to secure the lid and gasket in a sealed position on the container.
