The injection nozzle 20 has a cylindrical base end portion 21 provided on the lower side and a nozzle portion 22 formed in a reduced diameter on the upper side, and a flange portion 23 formed between them is provided. It is a member connected via a member, a spout 24 is formed at the upper end of the nozzle portion 22, and a locking convex portion 25 is provided around the outer peripheral surface of the base end portion 21. The ejection nozzle 20 is assembled in a state in which the base end portion 21 is inserted into the upper end portion of the fitting cylinder portion 11 of the valve member 10 and the locking convex portion 25 and the locking concave portion 15 are engaged with each other so as not to be easily separated. Has been done.

The overcap 30 is a topped tubular member provided with a cylindrical side wall 32 on the outer peripheral portion of a disk-shaped top wall 31, and is attached to the mouth tube portion 2 and the mouth tube portion 2 Note. The outlet nozzle 20 is covered. On the inner peripheral surface of the side wall 32 of the overcap 30, a female screw 33 that can be screwed into the male screw 2a formed in the mouthpiece 2 on the container body 1 side is formed, and a stopper is formed at the lower end of the side wall 32. The member 36 is formed.

The stopper member 36 is a ring-shaped stopper, which is formed between the side wall 32 and the container body 1. Further, the stopper member may have a C-shaped shape, and a knob portion may be provided. Further, although not shown, an easily cutable cutting portion may be provided at the lower end portion of the side wall 32, and a locking piece that can be fitted to the mouth cylinder portion 2 may be formed on the inner peripheral surface of the side wall 32. When the overcap 30 is opened, the cut portion may be broken by catching the locking piece on the mouth cylinder portion 2, and the stopper member 36 may be removed.

Next, the use of the pouring container will be described.
In the unused state before opening shown in FIG. 1, the outlet 6 is sealed by the valve body 14. Therefore, since the sealed state can be reliably maintained as compared with the above-mentioned conventional one-point valve, it is separated from the relatively viscous contents contained in the container body 1, especially water and the like. It is possible to prevent the water content of the contents from being poured out from the one-point valve and flowing into the valve member 10 and the flow path 26 of the pouring nozzle 20.

After the overcap 30 is rotated to open and the stopper member 36 is removed, the overcap 30 is screwed downward by the height at which the stopper member 36 is removed. At this time, the annular convex portion 34 on the lower surface of the top wall 31 comes into contact with the upper end of the nozzle portion 22, and the ejection nozzle 20 and the fitting cylinder portion 11 connected to the lower end thereof are moved downward.

The valve body 14 is in contact with the pedestal portion 5 and cannot move further downward.
Therefore, when the overcap 30 is further screwed downward, the weakened portion connecting the upper end portion of the connecting column portion 12 and the inner peripheral surface 11A of the fitting cylinder portion 11 as shown in FIG. 12a is cut, and only the fitting cylinder portion 11 moves downward.

The valve member 10 and the dispensing nozzle 20 are moved downward until the flange portion 23 of the dispensing nozzle 20 comes into contact with the upper end of the mouth cylinder portion 2, but the outer shape of the fitting cylinder portion 11 is tapered. Therefore, at this contact position, the fitting cylinder portion 11 is tightly fitted in the mouth cylinder portion 2 and is set in a non-movable state.

Further, since only the fitting cylinder portion 11 of the valve body 14 moves downward, the connecting piece 13 has a shorter distance between the upper end 13a and the lower end 13b in the height direction (the length of the connecting piece 13 in the vertical direction). Although the connecting piece 13 is elastically deformed so that the inclination angle with respect to the valve member 10 becomes loose, the connection between the inner peripheral surface 11A of the fitting cylinder portion 11 and the valve member 10 is maintained without being cut, so-called so-called. Functions as a one-point valve.

Next, the overcap 30 is screwed off to expose the pouring nozzle 20 to the outside, and then the body 4 of the container body 1 is pressed to increase the internal pressure inside the container body 1. Then, the valve body 14 is lifted away from the pedestal portion 5 and the outflow port 6 is opened. Then, the content enters the periphery of the valve body 14 in the mouth cylinder portion 2 through the outlet 6, and subsequently the gap S between the adjacent connecting pillar portions 12 or the gap between the connecting pillar portion 12 and the connecting piece 13. Since the contents flow into the fitting cylinder portion 11 constituting the valve member 10 via S and further flow into the flow path 26 of the pouring nozzle 20, the contents are poured to the outside through the pouring outlet 24 at the upper end of the nozzle portion 22. You can get it out.
Further, when the pressure on the body 4 is released to reduce the internal pressure in the container body 1, the valve body 14 is lowered and the outflow port 6 is sealed again, so that the pouring of the contents can be stopped.

Although the configuration of the present invention and its action and effect have been described above with reference to Examples, the embodiments of the present invention are not limited to the above Examples.

Further, in the above embodiment, the configuration in which the overcap 30 is screwed downward by screwing has been described, but the overcap 30 may be configured to move downward by sliding.

Further, in the above embodiment, the configuration in which the nozzle portion 22 is attached to the upper end of the fitting cylinder portion 11 has been described, but the upper end of the fitting cylinder portion 11 can be brought into contact with the lower surface of the top wall 31 of the overcap 30. When the top wall 31 directly moves the fitting cylinder portion 11 downward, the configuration may not include the nozzle portion 22.
