A foldable corkscrew comprised of a main body, a helical thread being introducible screwed into a cork, a lever arm serving as a fulcrum point against the neck of a bottle, and an extractor tool for removal of cork pieces floating within a bottle. The thread and extraction tool are attached to a first shaft, connected to the intermediate portion of the main body, for foldable connection of the thread and extraction tool relative to the main body. The lever is attached to a second shaft, connected to the second end of the main body, for foldable connection of the lever relative to the main body. The extraction tool, sized to fit within a bottle neck, has a proximal end attached to the first shaft and a distal end having a cup for containment of a cork and cork pieces.

The present invention provides an electric bottle opener, comprising: a housing with a cavity therein; a humidity sensor; a temperature sensor; a battery; a display unit for displaying a humidity value, or a temperature value or a remaining power of the battery; a motor; an on-off switch for starting or stopping the motor; a control circuit board electrically connected with the humidity sensor, the temperature sensor, the display unit, the battery, the on-off switch and the motor; and a cork screw for pulling a cork of the wine bottle; wherein the humidity sensor, the temperature sensor, the display unit, the battery, the on-off switch, the motor, the control circuit board, and the cork screw are installed in the housing; the cork screw is connected with the motor and is driven by the motor.

A bottle opener apparatus comprises a bottle rest configured to rest on a portion of a bottle placed within the bottle opener, a lower body collar attached to the bottle rest, an upper body collar slidably connected to the lower body collar, one or more levers attached to the upper body collar and to the lower body collar, the one or more levers configured to remove a bottle cap from the bottle and eject the bottle cap into the air when the upper collar slides relative to the inner collar in an ejection movement, one or more sensors configured to collect data when the bottle is placed within the inner collar, and a transmitter configured to transmit the collected data to an external receiver.
