Claims

[Scope of Claim for Utility Model Registration] (1) A substantially cylindrical body, a top plate that closes one end of the body, and an incision that projects from the top plate into a space surrounded by the body. In a cap that is attached to a bottle spout that is sealed with a thin film, the body 10 has a stop that comes into contact with the bottle spout on an inner wall surface that is an appropriate distance away from the top plate 12 and the opening. The center part of the top plate part 12 is a flexible spherical shell part 15 that bulges out on the opposite side of the body part 10, and the incision claws (18, 19 or 40, 41) have an edge 7. , which are elongated plate-like bodies having an arc-shaped or broken line-shaped cross section, and are provided in plural numbers in the center of the flexible spherical shell part 15 parallel to and rotationally symmetrical with respect to the central axis of the body part 10, In addition, in the cross section perpendicular to the axis, they are each arranged so as to be convex toward the central axis of the body 10, and in the longitudinal direction, their free ends meet the stop edge 7.
cap of the above-mentioned bottle, characterized in that it is given the necessary length to reach the vicinity of the plane containing the cap. (2) A pair of incision claws (18, 19 or 40, 41
) are provided parallel to and opposite to the central axis of the body (10). (3) Together with the incision claws (18, 19 or 40, 41) according to claim 2, at least one pair of auxiliary incision claws 30, 30 in the form of elongated thin plates, which are shorter than the incision claws 18, 19, are provided, respectively. 3. The bottle cap according to claim 2, wherein the flexible spherical shell part 15 is rotationally symmetrical with respect to the central axis of the body part 10. (4) A bottle cap according to any one of claims 1 to 3, wherein the free ends of the cutting claws (18, 19) comprise a pair of sloped surfaces forming a sharp cutting edge at the center thereof. (5) The bottle cap according to claim 3, wherein the free ends of the auxiliary cutting claws (30, 30) are formed of slopes that form sharp cutting edges at corner joints that are distant from the central axis of the body (10).
