A method for preserving wine or other oxygen sensitive items is disclosed. In some embodiments, the method involves injecting 0.15 gram to 0.5 gram of an inert gas into a container comprising wine and oxygen, without raising a pressure within the container above 10 psig, to form a barrier layer of the inert gas between the wine and the oxygen in the container without displacing all of the oxygen from the container.

A bottle includes a neck and an opening at an end of said neck. A closure member closing the opening is provided with locking means that secure the closure member to a rim of the opening. The locking means include a collar surrounding a neck portion of the neck and locking-levers that are hingedly connected to the collar. The closure member includes outwardly extending lugs that register with the locking-levers. The locking-levers include link members that releasable engage the lugs at a top surface thereof. The locking-levers are retractable to a closed position in which the link members clamp the closure member to the rim of the opening.

The present invention relates generally to a container that may be sealed and reclosed with a threaded closure. More specifically, the present invention relates to methods of manufacturing a metallic container having an opening with inwardly facing threads that are formed after a threaded closure is inserted at least partially into the opening. The container opening may be selectively sealed and reclosed with the threaded closure which releasably engages the container threads.

A system and method for easily operated self-releasing stopper/cork for bottles of compressed liquids. The corks have a gas bladder that is designed to be inserted in a bottle and inflated, the bladder having a ribbed or smooth exterior to complete the sealing of the bottle whereby a gas release mechanism can be activated by depressing a button on a cap or via an on-board micro controller and/or electro-mechanical release solution in the cap. Once the gas is released from the top of the bladder the pressure inside the vessel will collapse the bladder's bottom and eject the cork assembly from the bottle.

The present disclosure provides a container sealing plug, which includes a plug body and a first flexible member connected. The plug body configured to seal a receiving opening of a container body. The first flexible member connected to the plug body and having a first sleeving opening formed thereon, the first sleeving opening being configured to connect to the container body. A user can place food, liquid or other objects into the container body through the receiving opening of the container body, and then seal the receiving opening of the container body with the plug body, whereby air or water is effectively prevented from entering or leaking out the container body through the receiving opening of the container body and thus the long-term storage and freshness preservation of the content is guaranteed.

A receptacle includes an upper portion having a cylindrical portion and an open end and a lower portion depending from the upper portion, where the lower portion is tapered and has a closed bottom end. The receptacle may include a radially-extending annular ring with a flat or sloped bottom surface and disposed on an outer surface of the receptacle at a transition between the upper portion and the lower portion and/or a radially-projecting lip circumscribing the open end, which may be configured for inter-locking engagement with a mated cap inserted into the open end of the upper portion. Embodiments may include one or more longitudinally-oriented grooves formed in an inner surface of the upper portion. The receptacle may be a unitary plastic structure.

The invention relates to a capsule (1) for a flanged cork stopper, the capsule (1) having a body (2) comprising a top (3) and a cavity (4) inside which at least two anti-rotation splines (5) are arranged, and the capsule further comprising an axial retention chamber (6) disposed within said cavity (4), wherein retention chamber (6) is shaped to receive and axially retain a flange of a flanged cork stopper. The invention also relates to a capsulated stopper comprising a flanged stopper, the flange of which is attached to the capsule (1) of the invention. The invention further relates to the production process of said capsulated stopper.
