A bottle stopper adapted for self-opening and self-plugging a bottle, comprising a cylindrical cover having a bottom end and a top end. The cylindrical cover is sized and shaped to plug a bottle. A cartridge is encompassed by the cylindrical cover and has a fluid chamber; the cartridge also has at least one lateral protrusion thereon to form between the cartridge and the cylindrical cover. There is at least one fluid channel for fluidly connecting between a space below the bottom end and above the top end. A conduit having at least one inlet and at least one outlet is for fluidly connecting transferring the fluid of the fluid chamber to outside of the bottle stopper. An activation cap is mounted to push the conduit along a longitudinal axis of the cylindrical cover from a closed state to an open state.

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 application provides a cover body mechanism, wherein the cover body mechanism comprises a first cover body, a handle, a second cover body, a connecting base and a sealing ring, wherein a bottom of the first cover body is provided with a groove; wherein the connecting end is movably accommodated in the groove through the second channel opening and connected with the groove through a second rotating shaft; wherein the connecting ring is sleeved with an upper side of the second cover body, an upper end of the connecting arm is movably accommodated in the groove through the first channel opening and is connected with the connecting end through a first rotating shaft; wherein the sealing ring is capable of deforming outward and expanding with the rise of the second cover body, so as to be sealingly contact to an inner side wall of a storage cavity in the sealed tank body. The present application also provides a sealed container, wherein the sealed container comprises the cover body mechanism according to above-mentioned. The cover body mechanism and sealed container, resolved the problems of the existing handle and the end of the second cover that cannot be disassembled and the cover mechanism cannot be opened and closed with one hand.

Stopper assembly for a serving device configured to be positioned in a neck of a container, such as a bottle, wherein the stopper assembly comprises a body element arranged to fit in the serving device; a valve element mountable on the body element, wherein the body element extends substantially in a direction transverse to the valve element; and a handling element that is connectable to the valve element and extending in a direction substantially transverse to the valve element at an opposite side of the body element, such that the valve element is arranged in between the handling element and the body element.

The stopper is equipped with a stopper main body having a guiding path extending in an axial direction. A stopper member has a flow path extending in the axial direction and is inserted in the guiding path of the stopper main body. A sealing member inserts into the flow path of the stopper member in such a manner as to block the flow path. The stopper member is equipped with, at a position where the sealing member is inserted, a first peripheral wall section fixed in a manner as to extend in the axial direction and a second peripheral wall section separated from the first peripheral wall section in a circumferential direction and extending radially outward along the axial direction.

The present invention relates to a compression seal (1) for insertion into and sealing of an opening (2), having an elastomer body (5) and a tensioning bolt (7), wherein the elastomer body (5) can be deformed by tightening the tensioning bolt (7) and can thus be made to press in a sealing manner in directions perpendicular to a longitudinal axis (14) of the tensioning bolt (7), and wherein a tensioning element (8) having oblique faces (9a, b) set at an angle to one another is provided for the purpose of tensioning the elastomer body (5) and is braced between the tensioning bolt (7) and the elastomer body (5) such that, by displacement in its tapering direction (11) or an opposite direction, it can be brought into a tensioning state and thus the tensioning bolt (7) can be tightened and the elastomer body (5) can be deformed.
