BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap with a sealing function.

[0002]

2. Description of the Related Art Various types of screw cap sealing functions are on the market. As an example, a virgin seal is attached from above the screwed cap, and a cut such as a perforation in the circumferential direction or a discontinuous long hole is made in a part of this seal, and the cap is returned or picked up. It is a method of breaking the virgin seal at the cut and separating the seal from the cap.

[0003]

Although an extremely thin aluminum or synthetic resin material is used as the virgin seal, a large-scale mounting machine is required in any case, and in the case of aluminum, a considerable force is required for breaking. On the other hand, in the case of a synthetic resin material, breakage is easy, but if careless, there is a risk that the fingertip may be damaged at the fractured surface.
