A food storage container including a case having an open side and forming a storage space and a case cover configured to be detachably coupled to the case so that, when coupled to the case, the case cover covers the open side of the case and seals the storage space, the case cover including a receiving portion forming a receiving space configured to accommodate a gas absorbent, and having a discharge hole between the receiving space and the storage space, a valve to open and close the discharge hole in response to a pressure inside the storage space, and a receiving portion cover configured to be detachably coupled to the receiving portion so that, when coupled to the receiving portion, the receiving portion cover seals the receiving space, wherein a gas flowing from the storage space through the discharge hole to the receiving space is adsorbed by the gas absorbent.

A preservation device, configured to form an air tight seal when disposed on a bottle and/or a vessel, is used to preserve liquids and other items, such as foodstuffs, which spoil when exposed to oxygen for a period of time. The device comprises at least a container which contains an oxygen absorber to remove oxygen remaining in the bottle or vessel after it is sealed by the preservation device. The container or the oxygen absorber has a gas permeable, liquid impermeable membrane. The preservation device may include an air channel system to control the flow of the liquid to be dispensed from the bottle without requiring the removal of the entire stopper device from the bottle, to enable the liquid to be dispensed while only allowing a minimal amount of oxygen to enter the bottle, thus improving preservation.

A preservation device are used to preserve liquids and other items, such as foodstuffs, which spoil when exposed to oxygen for a period of time. The preservation devices are configured to form an air tight seal when disposed on a bottle and/or a vessel. The devices include a container, and disposed within the container is an oxygen absorber, which removes oxygen remaining in the bottle or vessel after it is sealed by the preservation device. Either the container or the oxygen absorber has a gas permeable, liquid impermeable membrane. The preservation device may also include a flow control mechanism that enables a liquid to be dispensed from the bottle without requiring the removal of the entire stopper device from the bottle. The preservation device may alternatively include an air channel system to control the flow of the liquid to be dispensed from the bottle without requiring the removal of the entire stopper device from the bottle. Such arrangements enable the liquid to be dispensed while only allowing a minimal amount of oxygen to enter the bottle, thus improving preservation.

A child resistant container can include a container body, a closed base, an open top, an exterior and a cap assembly configured to couple to the container body for closing the container. A cap assembly can include an inner cap configured to couple to a container body and an outer cap coupled to the inner cap. A first coupler can be coupled to the inner cap and a second coupler can be coupled to the outer cap and configured to optionally engage the first coupler. An outer cap can be configured to rotate relative to an inner cap when the outer cap is in one or more positions and to engage the inner cap when the outer cap is in one or more other positions. A child resistant container can be made from recyclable metal.

A canister including a canister body containing a bottom wall and at least one sidewall with inner and outer sidewall surfaces and an upper rim, and a closing element containing a top wall with an outer surface and an inner surface, and a fixing portion surrounding the top wall. The top wall or the bottom wall or at least one sidewall include a membrane region with a predetermined permeability. The fixing portion includes an elevated or recessed snap portion around its outer periphery shaped to correspond to the inner sidewall surface of the sidewall of the cylindrical canister body and form a snap connection with the canister body. The closing element is fixed to the canister body such that the outer surface of the top wall does not extend beyond the upper rim of the sidewall of the canister body.

A closure device for a container to provide a combined protection of inert gas and oxygen scavenger methods. The closure device comprises a body, a fastening member, one or more plurality of protrusions, a blister, a hollow shaft, and a seal member. The closure device is removably coupled to an open end of the container through a fastening assembly. The fastening assembly includes at least one of friction fit, a snap fit, a screw fit, or any of a variety of fastening mechanisms. The closure device provides a combined protection of inert gas and oxygen scavenger methods. This is beneficial because it prevents nutritional and organoleptic degradation processes of wine through oxidation while aids to preserve the fruitier and fresher aromas and flavors of the wine. The closure device is designed to fit snugly over the neck of the bottle and create an airtight seal.

A container 22 includes a shell 24 made from a polymer, for example PET, and incorporating a catalyst, for example a palladium catalyst. A closure 40 incorporates a plug which includes a source of hydrogen, for example a hydride. In use, with container 22 including a beverage and closure 40 in position, the headspace in the container will be saturated with water vapor. This vapor contacts the hydride associated with plug 42 and as a result the hydride produces molecular hydrogen which migrates into the polymer matrix of shell 24 and combines with oxygen which may have entered the container through its permeable walls. A reaction between the hydrogen and oxygen takes place, catalyzed by the catalyst, and water is produced. Thus, oxygen which may ingress the container is scavenged and the contents of the container are protected from oxidation.

Systems and methods for preserving oxidizable substances such as liquids or foodstuffs are disclosed. These systems incorporate a sealing device and an oxygen scavenging chemical or agent coupleable to the system. The oxygen scavenging agent can remove the oxygen from the headspace of a container such as a bottle of wine without reducing the pressure in the headspace to the extent that the flavor of the wine is adversely affected.

A device for the preservation of degradable substances (e.g. degradable by oxidation) such as liquids or powders, especially edible substances, beverages (e.g. wine), or foods (e.g. coffee) as well as oils, tobacco, pharmaceuticals, colorants or paints in an opened container, e.g. a bottle, exposed to the oxygen of the air is provided herein. Aspects of the invention include an apparatus for removing oxygen from an opened container or bottle by coupling the container or bottle to a shell that contains an oxygen absorbent material such as reduced iron.

An improved container for use in holding oxygen sensitive contents is provided. The container comprises a body having an open end sealed with a metal closure. The metal closure includes a metal structural layer, a polymeric interior coating layer and an oxygen scavenger layer interposed between the metal structural layer and the polymeric interior coating layer.
