[Conventional technology]

Conventionally, a pump mechanism including an elastic pressure operation valve is incorporated into a dispensing head provided at the tip of a container, and the pump mechanism is operated to dispense the contents of the container, such as cream. Third
Many proposals have been made, including the dispensing container shown in FIGS. 60-84566 as shown in FIGS.

In the case of the dispensing container shown in FIG. 3, a dome-shaped elastic valve body 3 is provided at the mouth 2 of the vessel body 1, and the inside of a dispensing cylinder 4 communicating with each of the vessel body 1 and the elastic valve body 3 is A slide valve 5 is provided, and the slide valve 5 is urged by a spring 6 in a direction to close the spout 4a at the tip of the spout cylinder 4 from inside. Contents 7
When dispensing, when the elastic valve body 3 is pushed and compressed, the slide valve 5 resists the elastic force of the spring 6 due to the pressure of the contents 7 pushed out through the communication passage 5a in the slide valve 5. Then, the tip spout 4a of the spout tube 4 becomes open and the contents 7 are poured out. In addition, a bottom plate consisting of a disk-shaped body 8 and a return prevention member 9 is slidably fitted on the inner circumferential surface of the rear end opening of the container 1, and as the contents 7 are reduced, the inside of the container 1 is When negative pressure is generated, the bottom plate correspondingly slides upward toward the tip of the container body 1 as the contents 7 decrease.

[Problems to be solved by the invention] By the way, in the case of the dispensing container shown in FIG. The bottom plate is fitted from the rear open end of the vessel 1 to seal the contents. After filling the contents, it is desirable to remove the air contained in the container body 1 and the contents.
None of the bottom plate members of the dispensing containers described in the above-mentioned publications is provided with an air vent hole or an air vent device.

Therefore, in these conventional examples, especially in the case of the dispensing container shown in FIG. After the air is removed, the bottom plate is elastically deformed and inserted into the inner circumferential surface of the container body 1, and the contents are sealed with this bottom plate.

However, when such an air venting means is employed, there is a problem in that the air remaining inside the container body after sealing and the air still contained in the contents cannot be effectively vented.

The present invention was devised in view of these conventional problems, and aims to provide a dispensing container that can sufficiently bleed air after filling the contents.

[Means for solving problems]

The present invention has the following configuration in order to solve the conventional problems.

That is, a dispensing head H equipped with a pump mechanism for dispensing the contents is provided at the tip of the container body 10, and an air vent slit 24 is provided near the open end of the rear end of the container body 10.

In addition, the movable bottom cover 22 is slidably fitted to the inner peripheral surface from the rear open end of the container body 10 in an air-liquid tight manner, and the return prevention plate 2 is inserted from the outside of the movable bottom cover 22.
3, it is possible to prevent the movable bottom lid 22 from moving back toward the rear open end of the container body 10. Further, at the lower end of the return prevention plate 23, a peripheral engagement portion 23a is provided which slides in an engaged state with the inner circumferential surface of the container body 10.

[Effect]

The container body 10 with the dispensing head H attached thereto is turned upside down and the contents are filled. After filling, the movable bottom cover 22 is inserted from the rear open end of the container body 10, and during this time the air trapped in the container body 10 is extracted into the atmosphere through the air venting slit hole 24. The movable bottom cover 22 passes through the air venting slit hole 24, and the movable bottom cover 22 passes through the air venting slit hole 24
The air bleeding ends when the position is further inside the container body 10 than the point 4. When this air removal is completed, the inside is also sealed. Next, by engaging the return prevention plate 23 with the outside of the movable bottom cover 22, the movable bottom cover 22 is prevented from returning.

〔Example〕

Hereinafter, an embodiment of the pouring container according to the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, a dispensing head H equipped with a pump mechanism is attached to the tip of the cylindrical container body 10. This spouting head H has a through hole 11 and a pressurizing port 12 opened at the end face of the tip of the container body 10, and a spouting pipe 18 is fitted into one of the through holes 11 and fixed to the end of the container. ing. In addition, the spouting pipe 18 has a long connecting belt portion 15 that covers and closes this tip opening.

A dome-shaped elastic valve 19 is attached to the other pressurizing port 12 so as to cover it, and the circumferential end of this elastic valve 19 is held by a presser flange portion 17 integrally formed over the spouting pipe 18. It is clamped and fixed from above. Furthermore, this elastic valve 19 has an on-off valve 20 on a part of its periphery.
is integrally molded, and the on-off valve 20 is housed inside the spouting pipe 18 to open and close the through hole 11. That is, the opening/closing valve 20 opens the passage in the tube by the pressure of pouring out the contents, and has an elastic force sufficient to block the through hole 11 by its own elasticity when the pouring pressure is released.

Next, the rear end of the container body 10 is an open end, and the movable bottom lid 22 extends from the open end of the container body 10.
It is slidably fitted in an air-liquid tight manner to the inner peripheral surface of the. That is, the seal flange 22 on the periphery of the movable bottom lid 22
By slidingly contacting the inner peripheral surface of the container body 10 in an air-liquid tight manner, the contents filled inside the container body 10 are sealed. Furthermore, a locking protrusion 22b is provided at the center of the movable bottom cover 22.

From the outside of the movable bottom cover 22 having such a shape,
