ことができる。Function When a heated liquid such as youth or alcoholic beverage is stored in a bottle and the bottle cap is fitted to the bottle opening 22 of the bottle, the heat of the heated liquid brought through the bottle causes the cylindrical portion 2 to close to the bottle opening. 22, the elasticity decreases and the sealing performance tends to decrease. However, a protrusion 6 is provided on the outside of this cylindrical portion 2, and a circumferential A cylindrical body 5 having an inner diameter smaller than that of the protrusion 6 is tightly fitted, immovably and in constant pressure contact in both the direction and the axial direction. Since it is made of synthetic resin with a melting point higher than the boiling point of water, the vicinity of the protrusion 6 is always kept at a constant level due to the so-called hoop, which is not affected by the heat produced by the heated liquid of juice or sake. Stress is applied, and in particular, the stress is applied by increasing the force per unit area.
The decrease in sealing performance due to the decrease in elasticity due to heating can be compensated for practically, although not completely, particularly in that area, and the decrease in sealing force can be kept to a minimum.

Further, 10 is a spiral groove, 11 is a fissure, 12 is a tearing member such as a bull ring, 13 is a spout, and 14 is a middle leg. However, the threaded engagement using the threads 9 and the threaded grooves 10 is not limited to this, and any engagement may be used. And in the figure, protrusion 6
is shown as being contained in the cylinder 5,
This is due to the difficulty of illustration; in reality, it is crushed between the cylindrical portion 2 and the cylindrical body 5. The lid body 4 was made of polyethylene, and the cylinder body 5 was made of polypropylene, for example.

きる。Effects of the invention This invention is constructed as described above, and the cylindrical portion 2
A protrusion 6 is provided on the outside of the cylindrical portion 2.
A cylindrical body 5 having an inner diameter smaller than the protrusion 6, which is immovably and in constant pressure contact with the outside of the ridge 6 in both the circumferential direction and the axial direction.
The cylindrical body 5 has a melting point higher than that of the synthetic resin forming the lid body 4;
In addition, since it is made of synthetic resin with a melting point higher than the boiling point of water, the vicinity of the protrusion 6 of the cylindrical portion 2 is affected by the heat generated by heated liquids whose main component is water, such as youth and alcoholic beverages. Not done. A certain amount of stress is constantly applied to the body due to so-called hoops,
In particular, since the stress is applied by increasing the force per unit area, the decrease in sealing performance due to the decrease in elasticity due to heating is almost compensated for, especially in that area, although it is not completely, it is practically sufficient. This makes it possible to keep the decrease in sealing force to a minimum.
