The present invention provides a bottle cap opener which makes opening sound when a bottle cap for sealing a bottle inlet is taken off from the inlet of a bottle in which beer, juice, or others are charged. An external movable container member (2) and an internal movable container member (3) are installed in the lower part of a cylindrical main body (1) to be able to move vertically. A bottom hook (5a) of a hook member (5) installed inside the internal movable container member is hooked at the bottom of the bottle cap (A) to take off the bottom cap (A) by pushing downward the cylindrical main body (1) in a state where the bottle inlet (b) is covered by the internal movable container member. A piston of a cylinder (20) mounted in the upper part of the cylindrical main body (1) moves upward with the external movable container member by moving upward the external movable container member to compress air in the upper part of the cylinder (20). A cover member (28) is instantaneously discharged from the top opening of the cylinder (20) by the compressed air pressure with exhaust sound. |
