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 bladder the pressure inside the vessel will collapse the bladder's bottom and eject the cork assembly from the bottle.

A freshness plug includes a solid round body having an internally depressed section, a protrusion extending from the internally depressed section, a shoulder extending from an exterior of the internally depressed section, and malleable flanges below the shoulder.

A method of preserving an oxygen sensitive item is disclosed. The method involves injecting at least 0.15 gram of an inert gas into a container comprising the oxygen sensitive item and oxygen, without raising a pressure within the container above 10 psig, to form a barrier layer of the inert gas between the oxygen sensitive item and the oxygen in the container without displacing all of the oxygen from the container.

A sealed pharmaceutical container comprises a flange comprising an underside surface, an outer surface extending from the underside surface, the outer surface defining an outer radius r.sub.o of the flange; and an upper surface extending between the outer surface and an inner surface defining an opening in the sealed pharmaceutical container. The upper surface comprises a sealing region extending between the opening and the outer surface and comprising a radius r.sub.sr that is less than r.sub.o. The sealed pharmaceutical container also comprises a sealing assembly comprising sealing portion in contact with the upper surface at a lower surface of the sealing portion and a cap compressing the stopper against the upper surface. After compression, the sealing portion of the stopper comprises a compressed radius r.sub.sc that is less than r.sub.sr adjacent the upper surface.

A method for manufacturing a closure constructed to be inserted and securely retained in a neck of a product-retaining container includes intimately combining a plurality of coated particles (each comprising a cork material core and a first plastic material) with a second plastic material, and other optional constituents; heating the composition to form a melt; extruding or molding a closure precursor from the melt; and optionally cutting and/or finishing the closure precursor. A composition for use in manufacturing a closure includes a plurality of coated particles (each comprising a cork material core and a first plastic material) with a second plastic material, and one or more blowing agents. Methods for producing particulate material, cork composite material, and additional method for producing closures are also provided.

A recyclable cap for containers includes an outer body and an inner body provided with fixing means for being retained in a container, the inner body being coupled and housed inside the outer body, wherein the outer body is made of a biodegradable material of plant origin, wherein the outer body and the inner body are coupled by coupling means configured for linking the two bodies to one another, the inner body including a single-use release system configured for separating the outer body from the inner body. A user may thereby separate and recycle the outer body and the inner body in an entirely separate manner at the end of the service life thereof.

A container arrangement is provided and is configured to maintain a predetermined amount of moisture in the container for storing a product, where the container arrangement includes a container with an upper container opening and a closed base, a stopper with a central hole for fastening the stopper to the container opening, a hollow chamber with a peripheral wall, an upper wall with a central hole and a lower perforated base wall, where the chamber is put together with the stopper so that the central holes are in alignment with one another and a substance is arranged in the chamber, where the substance is a consequence of the inflow of ambient air through the central holes, and gives off water, which passes through the perforated base wall.

An auto-lock sealing valve structure of a rubber jointing ring using the lid attached to the rubber jointing ring includes a lid, a rubber jointing ring, and a bottle body. The rubber jointing ring connects the lid and the bottle body. The designation of the vapor escaping groove in the lid body helps the air inside the rubber jointing ring escape out, simultaneously the raised edge on the bottle lid prevents the rubber jointing ring part from coming out off. The gaps on the body part of the rubber jointing rings help the air inside the bottle body to entirely escape but still ensure that the liquid inside the devices cannot escape.

Many embodiments described herein prevent an aged spirit from degrading due to the oxygen trapped in the headspace without the use of a pump. The aged spirit preservation system may have a cork with an open top, an open bottom, and a channel extending from the open top to the open bottom. The cork may be sized couple to an internal portion of a bottle. The system may even include a sealing device coupled to an outer portion of the cork between the open top and the open bottom. Additionally, the system may include a replaceable cartridge containing an adsorbent media, iron, a salt, and a color-changing indicator. Oxygen from the bottle may be allowed to enter the cartridge and react with the iron via a non-reversible reaction, thereby preventing the degradation of the spirit.
