The invention described herein relates to a threadless cap for a threadless bottle, the threadless cap comprising a threadless outer cap and a threadless inner cap, wherein the threadless inner cap is received in the threadless outer cap so as to define an annulus between them. When assembled, a bottle is received in the annulus with a portion of the threadless inner cap creating a plug that seals the bottle and a portion of the threadless outer cap over hanging the bottle. Both the outer cap and the inner sealingly engage the bottle using a threadless friction fit. To remove the cap from the bottle, one simply slides the cap off the bottle.

A tamper evident closure comprises a cap having a plug, a skirt and a locking member. The cap and the skirt have seats in which a first portion and a second portion of the locking member are arranged. Upon first opening, as the cap moves longitudinally away from the skirt, the lower edge of the cap passes over the first portion longitudinally so that, upon reclosing the closure, the first portion positions in an obstructive manner between the lower edge of the cap and the upper edge of the skirt.

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 or contained within 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 pouring spout sealing structure of an inside plug includes a sealing member including a bottom part for sealing an opening of a pouring spout of the inside plug, a peripheral wall rising from the peripheral edge of the bottom part, and a knob part extending from the peripheral wall, in which the sealing member is connected to the upper end of the opening of the pouring spout at the peripheral edge of the bottom part, the connected portion constitutes a thin part breakable by a certain pulling force, and the peripheral wall is inclined upwardly and outwardly from the opening of the pouring spout. The container pouring spout sealing structure achieves both sealability and easy opening properties, reduces number of parts and manufacturing steps, and is applicable to small containers such as cosmetic containers.

The invention relates to a self-extracting stopper which can be accommodated inside the neck of the bottle, and which does not require a corkscrew or any other tool for the extraction thereof, formed by an assembly of parts preferably made of a plastic material and which, once assembled, permit a bottle or container to be stoppered. The face of the drum (8) and the surface of revolution of the flexible cylinder (4) can also carry marks that are engraved or in shallow relief. In this way, the assembly of the self-extracting stopper is formed by six elements and a cork cover (1), a nut (2), a flexible cylinder (5), a drum (8), a screw (12) and a wing nut (15), all of which are disposed and assembled according to their axial geometry, and which permit a method and process to be provided whereby bottles and/or containers can be stoppered or opened manually or automatically, and said self-extracting stopper being reusable.

The present invention relates to devices for corking bottles, and more particularly to the corking of glass bottles having necks containing a cork with an upper portion which rises above a rim, and may be used for corking bottles. A device for corking bottles contains a neck with a rim, and a cork, an end portion of the rim having protrusions, providing the ability to raise the cork by rotating same by the upper portion thereof. The neck, rim and upper portion of the cork are rectangular and/or oval in horizontal cross-section. The neck and rim are, on the two wide sides thereof, made in the form of parallel flat common surfaces. The narrow sides of the rim are hook-shaped.

Provided is a wine stopper capable of being vacuumized, the wine stopper comprising a base capable of covering an outer side of a wine bottle, and a shell enclosing a cavity with the base. A boss capable of being clamped in a bottle opening is arranged on one side, away from the shell, of the base. The wine stopper further comprises a power source arranged in the cavity and a vacuum pump capable of creating a vacuum in the wine bottle, a through hole capable of communicating the vacuum pump with the interior of the bottle is provided in the boss, a measurement assembly capable of measuring a vacuum degree of the interior of the wine bottle is arranged in the cavity, and the measurement assembly is electrically connected with the vacuum pump.
