る。Hereinafter, the operation of the cap 1 when the cap 1 of the present embodiment is mounted on the container opening 21a having the male screw 22 will be described with reference to FIG. FIG.
As shown in (b), when the cap 1 is wound around the container opening 21a, the inner seal projection 4 is fitted into the container opening 21a and abuts against the inner wall surface 21b without any gap. Cap 1
When the screw portion 10 is further rotated in the closing direction, as the screw portion 10 moves in the circumferential direction along the male screw 22, the cap 1 is moved.
Moves down. At this time, the inner seal portion 4 is
1b is inserted into the container opening 21a against the frictional resistance generated between the container opening 21a. Since the cap 1 is screwed into the container opening 21a while receiving the frictional force from the inner wall surface 21b, when the opening end 21c of the container opening 21a reaches the top plate 2, the screw 10 is From the end 10a on the plate 2 side to the end 10b on the TE ring 9 side, the male screw 22 is in contact with the male screw 22 from below over the entire length (the state shown in FIG. 2B). In this state, a downward (obliquely downward) drag acts on the screw portion 10 by the male screw 22.

Will do. For example, in the illustrated example, the forming angle of the screw portion 10 is about 720 °.
(Approximately two rounds), the drag acting on the screw portion 10 is substantially uniform over the entire circumference.

ほぼ全周にわたって均等となる。In order to manufacture the cap 1, a synthetic resin material is compression-molded using an outer surface mold and an inner surface mold, the molded cap 1 is removed from the outer surface mold, and the inner surface mold is removed from the cap 1. A method of pulling out the mold can be adopted. As the inner surface mold, one having a shape conforming to the inner surface shape of the cap 1 is used. A thread forming groove is formed in the inner surface mold along the shape of the thread 10. When pulling out the inner surface mold from the cap 1, a force in the pulling direction is applied to the screw portion 10 by the screw portion forming groove. In this cap 1, since the circumferential forming angle of the screw portion 10 is set to 600 to 720 °, the force applied to the screw portion 10 by the inner surface mold uniformly acts on a wide range in the cap circumferential direction. become. For example, in the illustrated example, the forming angle of the screw portion 10 is about 720 °.
(Approximately two rounds), the force acting on the screw portion 10 is uniform over almost the entire circumference.

部に変形が生じやすくなる。In the cap 1 of the present embodiment, the circumferential angle of the threaded portion 10 is set to 600 to 720 °.
When mounted on the container opening 21a, the downward drag acting on the screw portion 10 by the male screw 22 acts uniformly over a wide range in the circumferential direction. Therefore, when the cap 1 is attached to the container opening 21a, the height of a part of the cap 1 in the circumferential direction is different from the height of the other parts due to the circumferential bias of the drag. Can be prevented. Accordingly, it is possible to prevent the cap 1 attached to the container opening 21a from being inclined, and to prevent an increase in opening torque and a decrease in sealing performance due to the inclination. Further, the appearance when the cap 1 is mounted can be improved. Furthermore, at the time of molding, particularly when pulling out the inner surface mold from the cap 1, the force in the pulling direction applied to the screw portion 10 by the screw portion forming groove,
It can act uniformly over a wide range in the cap circumferential direction. For this reason, it is possible to prevent the force in the pulling-out direction from locally exerting a large force on a part of the cap in the circumferential direction, and to prevent deformation of the screw portion 10. On the other hand, when the formation angle of the screw portion is small (for example, about 540 °),
Since the bias in the circumferential direction of the drag acting on the screw portion when the cap is attached increases, the cap tends to be inclined when attached. In addition, the bias in the circumferential direction of the force in the mold pulling direction applied by the inner surface mold during molding increases, and the screw portion is easily deformed.

変形を防ぐことができる。As described above, in the synthetic resin cap of the present invention, the circumferential angle of the threaded portion is 60 degrees.
Since the angle is 0 to 720 °, the drag acting on the screw portion by the container can be equalized in the circumferential direction, and the cap attached to the container mouth can be prevented from being inclined.
For this reason, it is possible to prevent the opening torque from increasing and the sealing performance from being reduced due to this inclination. Further, the appearance when the cap is attached can be improved.
Furthermore, at the time of molding, especially when pulling out the inner surface mold from the cap, the force in the pulling direction applied to the screw portion,
It can act uniformly over a wide range in the cap circumferential direction, and can prevent deformation of the screw portion.
