Abstract

PROBLEM TO BE SOLVED: To prevent remaining liquid left on an inward flange shaped top face of a discharge tube bottom end formed by a bottom wall aperture of a discharge cap with a pull-ring from leaking by being pushed out along the inner face of the discharge tube owing to high pressure gas in the container body in unscrewing a cap. SOLUTION: The bottom inner face of a discharge tube 6 of a discharge cap with a pull-ring is formed in a small diameter perpendicular face 12 and the intermediate inner face of the same in a medium diameter perpendicular face 13. On the peripheral wall 4 outer face of the discharge cap, the outer peripheral wall 22 of a cap is screwed. From this cap, an intermediate peripheral wall 23 is suspended airtightly contacting the medium diameter perpendicular face and an inner peripheral face 27 downward airtightly contacting the small diameter perpendicular face 12. The inner peripheral wall 27 is so made that the same parts from the small diameter perpendicular face quickly in unscrewing the cap, and the upstream part of a ventilation passage 36 communicating with an exhaust vent 24 provided in the outer peripheral wall or in the cap top wall is provided between the inner peripheral wall 27 and the intermediate peripheral wall 23.

For this reason, when the cap is removed in a state where the pressure inside the container is high due to a temperature change or a body elastic deformation caused by holding the body of the container, when 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 remaining on the upper surface of the inward flange-shaped portion was pushed up along the inner surface of the pouring 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.

The present invention has the above-mentioned construction, and in which a spout with a pull ring is fitted to the mouth and neck of the container body and a cap is screwed to the spout, The lower inner surface of the pouring cylinder 6 of the tap is formed on the small-diameter vertical surface 12, the middle inner surface is formed on the middle-diameter vertical surface 13, and the upper inner surface is formed on the tapered inner surface expanding upward and outward, respectively. The lower outer surface of the inner peripheral wall 27 hanging down from the lower surface is pressed against the small-diameter vertical surface 12, and the lower outer surface of the inner peripheral wall 27 is pressed against the medium-diameter vertical surface 13, respectively.
Since the seal contact surfaces 35 and 31 are formed, and the distance from the lower end of the second seal contact surface to the upper end of the middle diameter vertical surface is set longer than the distance from the lower end of the first seal contact surface to the upper end of the small diameter vertical surface 12, Alternatively, the upstream portion of the air passage 36 that communicates the exhaust hole provided in the outer peripheral wall with the space inside the injection cylinder below the first seal contact surface 35 through the first seal contact surface is formed by the inner peripheral wall 27 and the middle peripheral wall 23. After opening the bottom wall of the pouring cylinder, when the cap is unscrewed with residual liquid remaining on the inner surface of the lower part of the pouring cylinder and high pressure inside the container, the second sealing contact Before the surface 31 is eliminated, only the high-pressure air blows out through the air passage 36, and therefore, even if the second seal contact surface 31 is subsequently released, the high-pressure state in the container body has already been eliminated at this time. In addition, it is possible to prevent the residual liquid from further rising along the inner surface of the discharge cylinder and leaking.

If the diameter difference between the small-diameter vertical surface 12 and the medium-diameter vertical surface 13 is small, it is difficult to increase the gap between the middle peripheral wall 23 and the inner peripheral wall 27, and the gap is reduced. If it is small, it will be difficult to integrally mold the cap, but the outer peripheral wall
By fitting a first auxiliary cap body 28 having an inner peripheral wall 27 into a first cap main body 25 having a 22 and an intermediate peripheral wall 23, the gap between the intermediate peripheral wall 23 and the inner peripheral wall 27 is reduced, and It becomes easy to form an upstream portion of the ventilation path between the two peripheral walls.

From the second cap body 51 to the outer peripheral wall 22 and the intermediate peripheral wall
The second auxiliary cap body 41, which hangs down the 23 and the central cylinder 52, and is fitted into the second cap body, is fitted from the outer periphery of the bottom plate 42 to the outer surface of the central cylinder, and the reinforcing cylinder 43 is erected. By fitting the inner peripheral wall 27 down from the upper end via an outward flange and to the inner surface of the intermediate peripheral wall 23, the rigidity of the second auxiliary cap body 41 is increased, and the inner peripheral wall 27 is twisted with respect to the intermediate peripheral wall 23. In addition, it is possible to provide the first seal contact surface 35 at the time of unscrewing of the cap so that the first seal contact surface 35 can be eliminated simultaneously on the entire outer peripheral surface of the inner peripheral wall, so that the high pressure state in the container can be eliminated in a short time. I can do it.

The third cap body 63 having the fitting cylinder 62 and the third auxiliary cap body 65 having the inner peripheral wall 27 and the second fitting cylinder 64 are used to move the second fitting cylinder 64 to the outer surface of the first fitting cylinder 62. Is formed, it is easy to provide a gap between the middle peripheral wall 23 and the inner peripheral wall 27 in accordance with the difference in diameter between the medium-diameter vertical surface 13 and the small-diameter vertical surface 12. 22 By forming the exhaust hole 24 with a groove formed in one or both of the upper end surface and the lower end surface of the second fitting cylinder, even if a plurality of small exhaust holes are provided, the appearance of the cap is impaired.
