The invention provides an air pressure opener for opening grape wine bottle. It comprises a housing and an air pumping device for filling air into the wine bottle. The air pumping device comprises a cavity inside the housing and an air needle with an air channel. The head of the air needle is connected to the inner cavity of the housing, and the air passage in the air needle communicates with the inner cavity of the housing. It is characterized in that an air pressure relief device is provided that releases air from the inner cavity -when the air pressure in the inner cavity of the housing rises from atmospheric pressure value to a certain value. When the bottle is opened, the air pressure relief device timely vents the air in the bottle to prevent the bottle from bursting from the excessive air pressure in the wine bottle.

A bottle opener, comprising a cover, an inflating device, and a shell sleeved outside the inflating device. A valve plug assembly comprises a valve plug base, a valve plug, and a valve plug stopper. The outer wall of the rear end of an inner inflating tube is sleeved with a piston ring, and the outer wall of the top end thereof is sleeved with a stop component. The inner inflating tube is provided with a first through hole. An inflating needle passes through the first through hole and is fixed in the through hole. The cover is connected to the shell. This device opens a wooden cork by means of air pressure, thereby effectively protecting the integrity of the wooden cork and improves the tightness of the wooden cork during repeated use. The bottle opener is convenient to carry, avoids scratching, and achieves a protection effect.

A device for extracting a cork from a bottle. The device leverages an axial and rotational pulling force, and pressurized gas in the interior of the bottle to displace a cork from a bottle. The device provides a helical-shaped lever that axially and rotatably penetrates through the cork to forcibly extract the cork from the bottle neck. The helical-shaped lever has a hollow passageway that is in communication with the interior volume of the bottle. The device further includes a gas cartridge operated by a pressure release button that discharges pressurized gas through the hollow passageway of the helical-shaped lever, and into the bottle. The moment at which helical-shaped lever fully penetrates the cork, tension is removed from helical-shaped lever, releasing a compressed spring to expand. Expansion of spring presses spring against pressure release button; thereby forming tactile feedback and indicating optimal moment to discharge pressurized gas.

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 combined bottle opening and beverage preservation device and method is shown which provides a battery powered device that includes a non-coring needle that may be inserted through the cork/stopped or a bottle to transfer compressed air into the bottle which causes the cork/stopper to be expelled from the bottle. The same device may also be used to remove air from the bottle to preserve the remaining beverage contained in a bottle.

A device for removing a cork from a bottle, the device including: (a) a hollow needle, adapted to be inserted in the cork; and (b) pressurized gas sealed in an inner volume of a container; wherein the pressurized gas is adapted to be released from the container when a path of fluid communication is formed between a proximal end of the hollow needle and the inner volume of the container, such that the pressurized gas is channeled through the hollow needle, and into the cork or into the bottle, below the cork thereby forcing the cork out of the bottle.
