能を改善したキヤツプ。 As the neck shape of the container body hangs down in opposite directions below the mouth, a step part is formed from the overhanging top part that widens at the hem, and the part away from this is cut out in a reverse taper shape as it hangs down. The entire circumference at the base of the neck is a constricted part with a smaller diameter than the upper part, and the cap has a constricted part with a smaller diameter than the upper part. A structure that prevents the lower part of the inner cylinder of the cap body from expanding outward or pushes it inward by circularly moving the cap body consisting of the cap body and the lock body assembled on the top of the cap body. The protruding part protruding below the cylindrical part of the cap body is hooked onto the eave-like protruding step part extending in the radial direction from the widening apex of the protruding top surface of the neck of the container body. This improves the problem that the locking mechanism cannot work firmly unless the inner cylindrical part is further compressed in the radial direction because the fitting part wears out due to repeated fitting and opening operations, and it has a protruding part. The shape of the outer surface of the inner cylinder part is configured such that the distance from the axis increases as it moves in the circumferential direction,
A pressure plate of a locking body that is crimped on the outer surface side to prevent the inner cylinder from expanding outward or to be pushed inward is formed in a shape that gradually moves away from the axis depending on the degree of wear of the fitting part. A cap with an improved locking function, characterized in that the locking function gradually moves in the direction of movement of the outer surface of the inner cylinder part, and the locking function does not deteriorate even after long-term use.
