PURPOSE: To easily remove a cap by comprising an operating means for turning a closing means, and a spring means for energizing the operating means so that the closing means is located on a closed position. CONSTITUTION: A handle 202 and an operating means 222 are horizontally mounted on an upper part of a bottle cap, and the cap is entered into a cylindrical opening 232 formed in the handle. The handle and the operating means are firmly gripped so that the engagement metallic pins 234, 236 at both sides of the opening, and the bottle cap are firmly engaged with one another, and the handle and the operating means are rotated on a shaft 215 of a bottle neck portion, whereby the cap can be removed. An attachment member 204 is turned on the bottle cap to be inserted until the outer surface of the bottle neck portion is engaged with an annular shoulder portion 204a of the attachment member. During this motion, a closing handle 239 is moved in the direction to be separated from the bottle neck portion in a state that the handle and the operating means are gripped. The operating means is released when the bottle is firmly attached, whereby the closing handle 239 is surely moved into the bottle neck portion by a spring 224. |
