BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid dispensing container.

[0002]

[Prior art]

[Problem to be Solved by the Invention] When a certain amount of liquid is required at the time of use, conventionally, a measuring cup is prepared separately from a container body for storing the liquid, and a fixed amount of liquid is measured in the cup each time it is used. The method of using it is quite common.

[0003] However, such a method has various inconveniences, for example, a measuring cup is lost, the cup must be washed each time the measuring is performed, it is troublesome, and the measuring is time-consuming and troublesome. Or

The present invention proposes a liquid measuring and dispensing container which can solve the above-mentioned drawbacks of the conventional container, can quickly and easily discharge a constant amount of liquid, and can easily change the constant amount to be dispensed. It is intended to do so.

[0005]

In order to solve the above-mentioned problems, the spout and tap of the present invention is used by being fitted to and fixed to the upper end of the mouth and neck portion 8 of the container body 7, and the primary weighing device defined by the partition wall 4 is used. It has a chamber 5 and a lower secondary weighing chamber 6, the lower end of which is opened at one end of the bottom wall 10 of the secondary weighing chamber , and the upper end is partitioned.
Measure the liquid passage cylinder 11 that penetrates the wall and protrudes into the primary measuring chamber.
And open the upper end on the partition wall at the end opposite to the liquid passage cylinder.
A short tube portion 12 having a mouth and a lower end suspended in the secondary measuring chamber 6.
And a pouring cylinder 13 having a lower end opening through the center of the partition wall 4 into the secondary measuring chamber 6 and an upper end penetrating through the center of the primary measuring chamber top wall 3 and projecting upward. A pouring tap configured to be able to pour out the liquid in the secondary measuring chamber 6 to the outside, wherein the partition wall 4 is separated from the liquid passing cylinder and the short cylindrical portion, respectively.
A guide tube 14 having an upper end opened at the center and a lower end hanging down into the secondary measuring chamber 6 is provided, and a lower end portion of a pouring tube 13 rotatably fitted into the tube 14 is rotatably fitted. And
A window hole 19 extending upward from a lower end of the cylinder wall of the guide cylinder 14 on the side of the liquid passing cylinder 11 is formed, and a cutout portion 20 is formed above a lower end of the cylinder wall of the discharge cylinder 13 to form a discharge cylinder. 13
The height of the opening of the window hole 19 can be changed by the rotation of.

[0006]

The liquid in the container 7 is primary when the container 7 is fitted and fixed by fitting the fitting tube 9 to the outer periphery of the neck 8 of the container. Weighing room 5
Then, the liquid level is injected until the liquid surface reaches the opening of the liquid passage cylinder 11, and a fixed amount of liquid is measured in the primary measuring chamber 5. Next, when the container is rotated in the same direction to erect , the fixed amount liquid in the primary measuring chamber 5 flows into the secondary measuring chamber 6 via the short cylindrical portion 12.

Next, when the container is again inverted, the liquid in the secondary measuring chamber 6 flows out through the pouring tube 13, but the depth of the window hole 19 opened at the lower end of the cylindrical wall of the guiding tube 14 is reduced. In addition, since it can be changed by rotating the pouring cylinder 13, the pouring amount can be changed stepwise. For example, in the embodiment shown in FIGS.
In the embodiment shown in FIG. 9, the dispensing amount can be sequentially changed according to the rotation angle of the dispensing cylinder 13.

Since the liquid is constantly measured in the secondary measuring chamber 6 from the second time, a substantially predetermined amount of the liquid is discharged simply by inverting the container.
