不具合を生じさせた。However, in the above-mentioned conventional cap 100, the lower cap 1 is caused by the pressure applied when the cap 100 is mounted on the bottle.
The bottle holding portion 111 of 10 is elastically deformed so as to be pushed upward, but since the upper surface of the bottle holding portion 111 abuts on the end surface 121 of the upper cap 120, the bottle holding portion 111 immediately starts the elastic deformation and the upper cap immediately. When an upward force is applied to 120, the upper cap 120 bulges outward at this time, and as a result, the screwing of the upper cap 120 to the lower cap 110 is loosened.

There was a gap between 21 and the upper surface of the bottle holding portion 111. According to an experiment by the applicant, for example, the upper cap 120 is previously tightened with a tightening torque of 10 kg · cm to the lower cap 11 in advance.
When the cap 101 is assembled by tightening it to 0 and the cap 101 is attached to the mouth tube portion 100a of the bottle 100 by applying a force of 30 kg · f from above, the return torque for removing the upper cap 120 is 0. 79 kg / c
It has been confirmed to decrease to m 2 .
