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.

Methods and apparatus for liquid preservation according to various aspects of the present invention may comprise a vessel and a displacer. The displacer may be disposed in an interior volume defined by an interior surface of the vessel. The displacer may change the volume of the interior volume. An aperture at an apex of the displacer or vessel may allow air to escape from the interior volume as the displacer decreases the volume of the interior volume. An at least partially transparent displacement indicator may be positioned atop the aperture.

The present disclosure relates to a vacuum preservation device, comprising a drawer including a drawer panel at the front end of the drawer, and a handle assembly. The handle assembly is coupled to the drawer panel, wherein the handle assembly includes a door body sealing assembly and a handle. A preservation container body comprises a preservation container body fixing part and a preservation container body sliding part. An electric push rod is coupled to the preservation container body and is coupled to the preservation container body sliding part and to the preservation container body fixing part.

A system, apparatus, and method of storing food including a storage container having a base; a resilient liner nesting in the base, and a lid that interlockingly engages with the liner and/or base to close off access to foodstuffs retained in a compartment defined by the liner. A valve assembly in the lid is actuated by a pump to evacuate air from the liner's compartment and create a vacuum or near-vacuum condition therein. Apertures defined in the wall of the base allow air to flow into a compartment of the base as the resilient liner shrinks around the food. The closed storage container may be placed in a freezer to freeze the food therein. For defrosting, the base of the closed storage container is placed in a volume of water, some of which flows through the apertures in the base's wall and comes into direct contact with the liner.

A selectively sealable evacuable storage bag comprises a first side comprising a flexible waterproof bag material having a first peripheral shape, a thickness, a first inner surface and a first outer surface; an opposed second side of the bag material comprising a mirror image of the first side in corresponding engagement with the first side; a waterproof weld joining the first side to the second side and defining an opening and a storage chamber extending between them, the opening configured to receive an article; a valve disposed on the first side or the second side, the valve disposed in a conduit attached to respective side and extending from a conduit opening to an outlet opening; and a selectively openable and closable seal disposed proximate the opening and providing a watertight, dust tight, and airtight seal in a closed condition, wherein in the closed condition the storage chamber is evacuable.

Modular containers are formed in a collapsible fashion by flexible or rigid bodies and panels. A size of a modular container may be selected by inflating the modular container to a desired pressure or volume, coupling two or more bodies of the modular containers together, or mating the bodies of the modular containers to common bases or surfaces. The modular containers may be accessed via one or more openings in vertical or horizontal surfaces of such modular containers in order to load items into such modular containers or to unload the items therefrom. The modular containers may be assembled or collapsed manually or automatically, and transported to one or more locations separately or in stacks.

Methods and apparatus for liquid preservation according to various aspects of the present invention may comprise a vessel and a displacer. The displacer may be disposed in an interior volume defined by an interior surface of the vessel. The displacer may change the volume of the interior volume. An aperture at an apex of the displacer or vessel may allow air to escape from the interior volume as the displacer decreases the volume of the interior volume. An at least partially transparent displacement indicator may be positioned atop the aperture.

A pump mechanism for vacuum sealing an airtight cavity formed by a container and a lid, including a bore having a first one-way seal allowing air from the airtight cavity to enter the bore and blocking air inside the bore from returning to the airtight cavity and a second one-way seal allowing air inside the bore to leave the bore without returning to the airtight cavity and blocking air outside of the bore from entering the bore, a piston disposed inside the bore, and a chamber of air enclosed by the bore, the first and second one-way seals, and the piston, wherein actuation of the piston in a first direction causes air to evacuate the airtight cavity and enter the chamber through the first one-way seal, and wherein actuation of the piston in a second direction causes air to exit the chamber through the second one-way seal.

An evacuated bottle system including a bottle defining a hollow interior, the bottle having a neck with a rim defining an opening; a cap assembly supported on the bottle, the cap assembly including a funnel having a first portion and a second portion, the first portion being insertable within the interior of the bottle and the second portion engaging a portion of the bottle to support the funnel above the rim, the funnel defining a bore that fluidly communicates with the hollow interior of the bottle; a self-sealing membrane that covers the bore formed by the funnel to selectively seal the hollow interior of the bottle; a cap attachable to the bottle, the cap including a cover portion that extends at least partially over the self-sealing membrane to restrain movement thereof, the cover portion being axially spaced from the self-sealing membrane to define a gap that permits axial movement of the self-sealing membrane to selectively open the bottle to fluid communication outside of the bottle.

Disclosed are a container cover and a vacuum preservation container. The container cover comprises a cover body and an air extraction assembly, wherein a first through hole is provided in the cover body, the air extraction assembly comprises an outer cover and an inner cover, the inner cover is arranged on an upper end of the first through hole in a sealing manner, a second through hole and a third through hole are provided in the inner cover, the second through hole is in communication with the first through hole, a first one-way valve is arranged in the second through hole, and a second one-way valve is arranged in the third through hole.
