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.

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.

An automated stopper and opener includes: a sleeve housing that is able to fit within a neck of a container; a mechanical feature that is able to vary a force applied to an internal surface of the sleeve such that a seal is able to be formed or released within the neck of the container; and an electronic controller that is able to manipulate the force applied to the internal surface of the sleeve by at least partly directing operations of the mechanical feature. An automated stopper includes: a cylindrical sleeve; a mechanical element that fits within the cylindrical sleeve and has a variable outer diameter; a communication interface that is able to receive commands from a user device; and a controller that is able to interpret the received commands and direct the mechanical element to control the variable outer diameter. A system includes automated stoppers and a user device.

The present invention relates to a stopper for a bottle designed for commercial bottling of a beverage or liquid food, preferably a wine bottle, and a sealing element for sealing the stopper in the mouth of the bottle, which is separate from the bottle. The stopper comprises a stopper part for introduction into a mouth of the bottle, and a head part for remaining outside the mouth of the bottle, the head part having a diameter that is larger than that of the stopper part, wherein the stopper part comprises a an interlocking mechanism for engaging with a counterpart interlocking mechanism of the sealing element. The sealing element is configured to be forced against an inner wall of the mouth, thereby being brought into a sealed position, upon introducing the stopper part into the mouth, in which sealed position the stopper is held on the bottle. The interlocking mechanisms are configured to permit bringing the sealing element into an unsealed position by an unsealing action which comprises rotating the stopper with respect to the bottle.

The present invention relates to a tamper detection capsule (1) of container comprising an upper cover member (2), a spring support inner member (3), a spring member (4) and a lower cover member (5), wherein spring member (4) is moveable between i) a first closed position in which it is arranged on inner member (3), and ii) a second open position, in which it is arranged between inner member (3) and upper cover member (2) in order to block the capsule (1) mechanism in the second open position. The invention further relates to an operating method of the tamper detection capsule (1), which is intended to close beverage containers.
