Claims

[Scope of utility model registration request]

The inner cap, which has a sealing member fixed to the opening edge deep inside the cap outer cylinder, is biased by a spring toward the opening of the cap main body so as to be movable in the axial direction. The cap is constructed by installing a cam groove consisting of an axial guide groove and a circumferential locking groove communicating with the tip of the guide groove on the inner surface of the outer cylinder of the cap. A sealed portion that is inserted into the inner cap is installed, and a seal shaft portion that comes into contact with the sealing member is provided behind the sealed portion, and furthermore, a projection that can be fitted into the cam groove is provided at a predetermined location on the circumference of the outer surface of the shaft portion at the rear thereof. The cap and the fitted body are configured such that the seal shaft portion is in contact with the sealing member, and the inner cap is retreated a required distance until the spring is slightly compressed. 1. A cap fitting device characterized in that the dimensions of each part are set so as to reach the position shown in FIG.
