There is no such thing as forming.

The liquid dispensing container of the present invention shown in FIGS. 1 to 13 is as follows:
Since it is configured as described above, when using it, first, when the liquid dispensing container is inverted as shown in FIG.
is injected into the measuring chamber 71 of. This injection is carried out in the metering chamber 71.
When the liquid level inside rises and blocks the air hole 39° at the upper end of the air displacement pipe 39 and air displacement is no longer performed, it stops.
As a result, a predetermined amount of liquid W is accommodated in the metering chamber 71.

Note that the amount of liquid W measured in the measuring chamber 71 is determined by the amount of liquid W measured in the measuring chamber 71
This can be adjusted by changing the depth at which the cylindrical part 7 is fitted into the fitting and locking cylindrical part 62 of the top plate part 6.

Next, when the liquid dispensing container is erected as shown in FIG.
3 and flows into each storage chamber 33 in a predetermined measured amount. This inflow causes the liquid level in each storage chamber 33 which is communicated with each other through the communication portion 34 to rise, and the measuring body 5
It stops when air is no longer replaced when it comes into contact with the lower end of the fitting locking cylinder part 62 in the top plate part 6.

Note that when the total volume of the storage chamber 33 is larger than the volume of the metering chamber 71, the liquid W flowing from inside the metering chamber 71 flows into the metering body 5.
This inflow is completed without the liquid level rising to the lower end of the cylindrical portion 7.

Finally, when the liquid dispensing container is again inverted or tilted downward as shown in FIG. Through the storage chamber 3 on the sloped side of the liquid dispensing container
3 and is poured out from the spout 61 corresponding to the storage chamber 33 on the inclined side. At this time, the liquid W in the storage container 1 is injected into the measuring chamber 71 as in the case of FIG. 14.

If the liquid dispensing container of the present invention does not have the communication part 34, when the liquid dispensing container is inverted or tilted downward, the dispensing will depend on which side of the liquid dispensing container faces downward. The amount is different. That is, in such a case, when dispensing, the liquid metering container is not necessarily completely inverted, and even if it is completely inverted, the liquid W is When dispensing is performed in such a state, the amount of liquid W flowing back from each storage chamber 33 to the measuring chamber 71 depends on which side of the liquid dispensing container is directed downward. This is because they are different. On the other hand, in the liquid metering container of the present invention in which the communication portion 34 exists, the liquid W stored in each storage chamber 33 follows the inclination of the liquid metering dispensing container as described above.
Since the liquid W passes through the communication part 34 and collects in the storage chamber 33 on the inclined side of the liquid dispensing container, there is almost no backflow from the storage chamber 33 to the measuring chamber 71, and the amount of liquid W poured out from the spout 61 is uniform. It can be done.

Therefore, according to the liquid dispensing container described above, by repeating the vertical and inverted positions, a predetermined amount of liquid flows into the storage chamber 33 from the measuring chamber 71 and the storage chamber 3
A predetermined amount of liquid flowing into and contained in the spout 61
It can be poured from.

By repeating the above operation, even if the bottom wall portion 4 is not located within the mouth and neck of the container 1, the injection path 32 is connected to the notch 38 of the outer cylinder portion 35 of the reservoir 2 of the container 1. Since it is possible to open into the mouth and neck, the injection channel 32
If the upper surface of the container 1 is located within the mouth and neck of the container 1, the liquid W in the container 1 can be poured out from the injection path 32 until the container 1 is substantially empty.

FIG. 17 shows another embodiment of the present invention, in which the liquid dispensing container of this embodiment has an unmanned cylindrical body 72 instead of forming the cylindrical part 7 of the measuring body 5 as a cylindrical body with a cylinder. and a top plate 73, and a fitting locking cylinder part 6 in the top plate part 6 of the measuring body 5.
No cutout is provided at the lower end of the storage body 2, and the lower end is connected to the storage body 2.
The structure is exactly the same as that of the embodiment shown in FIGS. 1 to 13, except that it does not reach the upper surface of the injection path 32 in the reservoir body 3.

Various embodiments of the liquid dispensing container of the present invention have been described above, and the liquid dispensing container in these embodiments includes a liquid dispensing device constituted by members other than this in the storage container 1. Although it is preferable to have such a configuration, the liquid dispensing container of the present invention is not limited thereto. Furthermore, in the liquid dispensing container of the present invention, the injection pipe 31 may be extended to the vicinity of most of the cylindrical portion 7 in order not to reduce the amount of liquid W flowing back from the metering chamber 71 to the storage container 1. Alternatively, the lower end of the cylindrical portion 7 of the measuring body 5 may not be narrowed toward the center. or,
The injection path 32 may be inclined. Moreover, the top plate part 6 and the cylindrical part 7 of the measuring body 5 can be formed into one piece, and in that case, if they are made of hard plastic, it is relatively difficult to squeeze the lower end of the cylindrical part 7. It is preferable to use a soft plastic that can be easily squeezed. Further, the number and size of the pouring ports 61 are appropriately determined depending on the liquid used in the liquid dispensing container of the present invention, and the number and size of the injection passages 32 and air displacement pipes 39 are similarly selected as appropriate. Further, in the embodiment, the storage body 2 is composed of a separable member including the storage body main body 3 and the bottom wall portion 4, but the manner in which these are divided or connected is arbitrary.

〔Effect of the invention〕

In the liquid quantitative dispensing container of the present invention, the injection path is provided in the bottom wall of the storage body in a radial manner approximately centered on the central axis of the mouth and neck of the storage container, so that the mouth and neck of the storage container have a sufficient amount of water. Even if the injection path does not have a long length, by providing the upper surface of the injection path within the mouth of the storage container, the entire amount of liquid in the storage container can be poured into the measuring chamber, and the liquid can be partitioned by the injection path. Since the storage chambers are not connected to each other through the communication portion, the amount of liquid dispensed can be made uniform no matter which side of the liquid dispensing container is directed downward. The structure is extremely simple, the product cost is low, and the advantages are extremely excellent.
