In a hinge cap with a virgin mechanism that is brought into contact with the thin film portion of the plug to cut and open the thin film portion, the lower end portion outer peripheral surface of the inner plug is projected radially outward from the inner cap, and when the lid body is screwed, A plurality of support pieces are provided which are separated by contacting the lower end of the cylindrical portion of the lid body, and a cylindrical member is provided which is connected to the tip of each of the support pieces and into which the cylindrical portion is fitted.

[0010] According to the above configuration, opening of the container, that is, opening of the inner plug, is performed as follows. By turning the lid body in one direction relative to the inner plug, the lid body is screwed downward. At this time, the inner plug opening means provided on the lid body also moves in the direction of the inner plug while rotating in conjunction with the inner plug opening means. Then, the sharp portion at the tip of the inner plug opening means comes into contact with and pierces the thin film portion of the inner plug, and then rotates along the thin film portion to cut the thin film portion.

At the same time, the lower end of the cylindrical portion of the lid body contacts the upper surface of the plurality of support pieces provided on the inner plug and pushes the support pieces downward. The support piece is broken, the cylindrical member is separated from the inner plug, and the cylindrical portion is fitted into the cylindrical member held on the neck of the container opening. Accordingly, by observing a change in the appearance of the cap in which the cylindrical portion of the lid body is fitted into the cylindrical member, it can be easily confirmed whether or not the inner plug of the container has been opened. Also,
Even in an opaque container, it is possible to easily confirm whether the inner plug has been opened or not.

In the hinge cap with a virgin mechanism according to a second aspect of the present invention, the outer peripheral surface of the lower end of the cylindrical portion of the lid body is formed to be tapered by inclining the outer peripheral surface, while the inner diameter of the cylindrical member is the cylindrical shape.
