The third seal cylinder 34 is suspended by being slidably fitted to the center.

The compression cylinder 31b has a cylinder lower end fitted into the upper inner surface of the connecting cylinder 33 so that it cannot be pulled out, and a tapered cylinder 36 with an upper small-diameter second window hole 35 is raised from the upper end of the cylinder lower portion. A gas venting cylinder 38 with a check valve 37 is erected from the upper end of the cylinder. The lower end of the degassing cylinder is formed at the large inner diameter portion, and the outer surface of the small outer diameter portion 16a formed by the upper end portion of the liquid passage cylinder 16 is fitted into the large inner diameter portion. The degassing valve 39 is formed by the inner surface of the large inner diameter portion and the outer surface of the small outer diameter portion, or by the inner surface of the lower end portion of the degassing cylinder 38 and the upper surface of the upward stepped portion. The degassing cylinder 38 has an intermediate portion as a large inner diameter cylindrical portion, and a ball valve is fitted into the large inner diameter portion.The upper end of the inner surface of the large inner diameter portion is a valve seat 40, and the lower end is a ball valve drop prevention protrusion 41. 3, when the gas vent valve 39 is open, the gas is discharged through the gas vent cylinder 38, but when the container is inverted as shown in FIG. 4, the ball valve is located at the upper valve seat. The liquid in the container is provided so as not to flow out through the degassing cylinder in contact with 40. A plurality of liquid outflow grooves 42 are provided vertically on the outer surface of the degassing cylinder 38.

  As shown in FIG. 3, the tapered cylinder 36 is formed so as to be elastically compressed by depressing the degassing cylinder 38 from the opened state of the degassing valve, so that the cylindrical wall between the plurality of second window holes 35 is formed. The portion may be formed narrow so that the elastic compression is easy, and the tapered tube may be formed to be stretchable by a plurality of screws.

  When the intermediate cylinder member 31 is screwed up from the lowered state shown in FIG. 2, the gas vent valve 39 is opened as shown in FIG. 3, and when the upper limit is reached, the second engaging protrusion 32 on the inner surface of the lower end of the female screw cylinder is the male screw cylinder. By engaging with the lower surface of the first engaging protrusion 21 on the lower outer surface, the third sealing tube 34 is in watertight contact with the upper inner surface of the second sealing tube 18 at its lower inner surface.

  The outer cylinder member 51 erected from the upper end of the lower cylinder part 52 fixed to the outer surface of the female threaded cylinder 31a, the intermediate cylinder 53 covering the outer surface of the compression cylinder via the inward flange, and the degassing cylinder 38 from the upper end of the intermediate cylinder The upper cylinder 54 is erected so as to cover the outer surface.

  The intermediate cylinder 53 has a tapered shape with a small upper diameter similar to the compression cylinder 31b, and the upper cylinder 54 has an inner diameter substantially the same as the outer diameter of the degassing cylinder 38. The liquid outflow groove 42 vertically provided on the outer surface of the degassing cylinder may be provided vertically on the inner surface of the upper cylinder 54. A fourth seal cylinder 56 is suspended from the lower end of the intermediate cylinder 53, and the fourth seal cylinder is fitted in an airtight manner to the outer surface of the connecting cylinder 33 of the intermediate cylinder member.

  The lower surface of the joint between the upper end of the intermediate cylinder 53 and the lower end of the upper cylinder is in airtight contact with the outer surface of the upper end of the compression cylinder 31b to form a liquid outflow valve 55.

  As shown in FIG. 1, the cap 61 has an upper small diameter from the upper end of the lower peripheral wall 62 covering the outer surface of the lower cylindrical portion 12 of the base cylindrical member 11 and the lower cylindrical portion 52 of the outer cylindrical member 51 via the downward inward flange 63. A tapered upper peripheral wall 64 is erected, and a mouth cap 66 is provided to be fitted from the upper end of the upper peripheral wall to the outer surface of the upper cylinder 54 of the outer cylinder member 51 through the upper inward flange 65.

  The lower inner surface of the lower peripheral wall 62 is screwed into the outer surface of the lower cylinder portion 12 of the base cylinder member, and the inner surface of the peripheral wall 67 of the mouth cap is airtightly fitted to the outer surface of the upper cylinder 54 of the outer cylinder member 51.

In this state, the first seal cylinder 17 is fitted to the inner surface of the mouth-and-neck portion 2, the third seal cylinder 34 is fitted to the inner surface of the second seal cylinder 18, and the fourth seal cylinder 56 is fitted to the outer surface of the connecting cylinder 33. Further, since both the gas vent valve 39 and the liquid outflow valve 55 are closed, the gas in the container is not released.

  As shown in FIG. 3 from the state of FIG. 2, when the outer cylinder member 51 is turned in the female screw cylinder unscrewing direction, the lower cylinder portion and the female screw cylinder 31a are fixed to each other. Together with the member 51, the screw 51 rises, so that the gas vent valve 39 is opened, and the gas in the container is released through the gas vent cylinder 38.

  When the container is tilted from the state of FIG. 3 as shown in FIG. 4 and the upper end of the degassing cylinder 38 is pressed against the coated surface 71, the depressurization cylinder 31b compresses the compression cylinder 31b that supports the degassing cylinder. Therefore, the liquid outflow valve 55 is opened by the lowering so that the liquid in the container flows out from the upper cylinder 54 and is applied through the valve. I can do it. When the degassing cylinder is pressed and released, the compression cylinder 31b is elastically restored and the liquid outflow valve 55 is closed.

It is a longitudinal cross-sectional view of this invention container main part shown in a cap fitting state. It is a longitudinal cross-sectional view which removes a cap from FIG. It is a longitudinal cross-sectional view which shows the state which raised the intermediate member and the outer cylinder member from the state of FIG.
