Provided is a lid assembly for a container. The lid assembly includes a lid formed of a first material and a seal formed of a second material and being integrally formed with the lid. The lid can be attached to the container such that a radially outwardly extending flexible lip of the seal compresses against an inner surface of the container to seal the lid assembly to the container.

Container assemblies and methods suitable for cooking, transporting, and storing the contents of the container assemblies while maintaining the contents therein at a desired temperature. Such a container assembly includes a container having a lower wall, side walls, and an opening opposite the lower wall that provides access to a cavity within the container. The container assembly further includes a lid configured to releasably attach to the side walls and thereby enclose the cavity to define a storage compartment. A thermal mass is coupled to an interior side of the lid such that at least a portion of the thermal mass faces and is exposed to the storage compartment when the lid is attached to the container. The thermal mass is configured to be heated to an elevated temperature or cooled to a reduced temperature and maintain the elevated or reduced temperature for a period of time.

A stopper for closing sparkling and other non-pressurized beverage containers. A stopper body may have a carrier member and lip engagement member arranged for sliding movement relative to each other and relative to the stopper body. The lip engagement member may be arranged to engage with a lip of a container neck, and be resiliently biased to move toward the carrier member to provide a seal-forming force on a sealing surface of the stopper body. The stopper may be arranged to introduce gas into the container, e.g., to re-pressurize the container to keep a carbonation level of beverage during storage.

A container assembly includes a lid, a gasket connected with the lid, and a container body. The gasket includes an outer peripheral edge. The container body may include an inner surface, an upper opening defined by a peripheral top edge, and at least one discontinuity where the inner surface or the peripheral top edge deviates in shape from the outer peripheral edge of the gasket. The container assembly may also include an inner container where the gasket includes an inner edge spaced inwardly from the outer peripheral edge. The inner container includes a top opening defined by a peripheral upper edge, and is receivable in the container body. The outer peripheral edge of the gasket seals against an inner surface of the container body and the inner edge of the gasket seals against an internal surface or the peripheral upper edge of the inner container.

A vacuum freshness preservation container that can be pressed on two sides provided in this application includes a container body and container cove. The container cover has chambers disposed symmetrically, a piston is slidably disposed in each chamber, and each chamber has an air outlet which communicates with an interior of the container body and where a first check valve is disposed. The piston is provided with an air discharge structure that communicates the chamber with an outside when the piston moves toward the first check valve, and the container cover is provided with a linkage mechanism such that the two pistons move in opposite directions. By alternately pressing pistons in two chambers, the chambers always keep in a vacuumizing state, thereby achieving a higher efficiency.

A vacuum canister includes a canister body and a cover body, wherein the cover body has a cover seat with an opening facing upwards, a through rod is disposed on a bottom wall of the cover seat, a valve seat is disposed at a lower opening end of the through rod, and a check valve is disposed on the valve seat. The cover seat is provided with an air extracting device including an inner barrel and an outer barrel. An opening end of the outer barrel is sleeved on the inner barrel. A through hole is axially opened in the inner barrel. The through rod passes through the through hole. The air extracting device includes a pressing handle sleeved on the outer barrel, wherein a lower end of the pressing handle abuts the push block. A limiting block is disposed on an outer circumferential wall of the pressing handle.
