となって溜ることとなる。The thin wire for breaking formed in the bottom wall of the pouring cylinder is formed by the liquid pouring from the pouring hole and the outside air flowing into the container in place of the pouring liquid. In order to perform the replacement well, the pouring hole is provided so as to have an elliptical shape or a bar shape. After the pouring hole is opened, the outer peripheral portion of the bottom wall is left at the lower end of the pouring cylinder in an inward flange shape. . Then, after the liquid is poured, the liquid attached to the inner surface of the pouring cylinder remains on the upper surface of the outer peripheral portion of the bottom wall as residual liquid.

よう設けたものである。For this reason, when the cap is removed in a state where the pressure in the container is high due to temperature change or elastic deformation of the body caused by gripping the body of the container, the lower end of the inner peripheral wall of the cap moves upward from the inner surface of the pouring cylinder. At the same time, the high-pressure air in the container is released through the threaded portion between the spout and the outer peripheral wall of the cap. At this time, the liquid accumulated on the upper surface of the inward flange-shaped portion was pushed up along the inner surface of the injection cylinder by the high-pressure air, and leaked through the threaded portion. The present invention is provided so as to prevent the above-described liquid leakage.

に残る付着液は自重により流下するものである。The above-described pouring tap 3 and cap 21 are each formed of a synthetic resin material. In the illustrated example, the cap 21 is removed from the closed state of the container shown in FIG. 1, and the removing plate 8 is removed by pulling up the pull ring to discharge the liquid. After the liquid is poured, the cap is screwed.When the liquid is poured again, if the pressure inside the container is increased due to a rise in temperature or elastic deformation of the body due to the body grip, the cap 21 is screwed up. First, when the inner peripheral wall 28 separates from the small-diameter vertical surface 12, the residual liquid 32 remaining on the outer peripheral portion of the bottom wall is discharged by high-pressure air ejected through the exhaust passage 31 by dissolving the first seal contact surface 28a. It is pushed up along the inner surface of the cylinder 6, but at this time,
Since 29 is in contact with the middle diameter vertical surface 13, it is prevented from rising by the lower end surface of the middle peripheral wall, and only high-pressure air is blown into the outside air through the exhaust path 31. Subsequently, the middle peripheral wall 29 separates from the medium-diameter vertical surface 13, but at this time, since the high-pressure state in the container body has already been released by the above-described ejection, the middle-diameter vertical surface 13
The remaining adhesion liquid flows down by its own weight.

外面は中径垂直面13へ気密に圧接する。In the third embodiment, the removing plate 8 is removed in advance. In the cap removal state, the third auxiliary cap body 54 is stopped with the plate-shaped ring 43 descending to the lower end of the sliding space 52 and the lower end edge of the ring outer surface being in contact with the upper surface of the engaging ridge 53. When the outer surface of the lower end portion of the middle peripheral wall 29 comes into contact with the middle diameter vertical surface 13 by the cap screw engagement with
The auxiliary cap body 54 stops, only the third cap body 51 descends, and the lower outer surface of the inner peripheral wall 28 contacts the small-diameter vertical surface 12 and hangs down as it is. Further, the third cap main body is lowered, and the plate-shaped ring 43 comes into contact with the lower surface of the top wall 23, whereby the third auxiliary cap body 54 is lowered together with the third cap main body, and the lower outer surface of the middle peripheral wall 29 is moved to the middle diameter vertical surface 13. Press tightly.

Although the third cap main body 51 is raised by the cap screw rising from this state, the third auxiliary cap body 54 does not rise until the plate-shaped ring 43 comes into contact with the engaging ridge 53. Accordingly, a gap is formed between the plate-shaped ring 43 and the top wall 23, and the gap is formed between the inner peripheral wall and the intermediate peripheral wall via the vertical groove 55, and between the outer peripheral wall 24 and the outer peripheral wall. The gap between the middle peripheral wall and the spout portion communicates with the gap, and the gap forms the exhaust passage 31.

止できる。According to the present invention, the inner peripheral wall 28 is separated from the small-diameter vertical surface 12 before the inner peripheral wall 29 is separated from the middle vertical wall 13 of the pouring cylinder, and the high-pressure air in the container is exhausted. Since the liquid is discharged to the outside air through 31 and the lower portion of the inner peripheral wall 29 is pressed against the vertical vertical surface 13 at this time, the residual liquid adhering to the upper surface of the outer peripheral portion of the bottom wall at the lower end of the pouring cylinder is provided. 32
Is pushed up to the lower end of the inner peripheral wall 29, but is not pushed up to the outer surface of the upper end of the pouring cylinder, so that leakage of the remaining liquid can be prevented.
