Description

[Detailed description of the invention] [Industrial application field] The present invention is a variable quantity discharge container for liquid, specifically, a container that can discharge a fixed amount of liquid contained in the container, and also allows the fixed amount to be changed. This relates to a container that can be used as a container.

[Conventional technology]

When using various liquids such as mouthwashes, water brushes, shampoos, hair washes, etc. stored in containers, it is convenient to be able to take out only a certain amount depending on the purpose of use. A liquid metering discharge container that takes out only a fixed amount of liquid has a measuring chamber or storage part that can hold a fixed amount of liquid, and this measuring chamber has an overflow type, a switching valve type, a pneumatic
A variety of devices have been developed that allow a certain amount of liquid to be put in, such as by utilizing surface tension.

[Problem that the invention attempts to solve]

However, all of these conventional types have complex structures, high costs, are difficult to operate, and furthermore, they have problems such as the inability to change the set discharge amount of the required liquid depending on the purpose of use. There were flaws.

SUMMARY OF THE INVENTION In order to eliminate the above-mentioned drawbacks of the conventional art, it is an object of the present invention to provide a variable discharge container for liquids which is simple in structure and operation and is capable of changing the set discharge amount of liquid.

[Means for solving problems]

In the present invention, a container body 3 is formed by a cylindrical part 1 and an expandable bellows part 2 connected to the upper part of the cylindrical part.
In this liquid discharge container, a lid body 4 having a discharge nozzle 8 connected to a discharge pipe 7 communicating with the inside of the container body is rotatably attached to the bellows part 2, the outer periphery of the cylindrical part 1 A sloped step 10 is provided on the surface, and a protrusion 9 that abuts the step 10 is provided on the lid 4, so that the distance between the step and the protrusion is adjusted along the outer peripheral surface of the cylindrical portion 1. The variable quantity discharge container for liquid is characterized in that the protrusion is configured to be relatively movable along the outer circumferential surface of the cylindrical part so as to vary the amount of liquid.

[Effect]

In this container, the distance between the projection 9 and the step 10 is set depending on the amount of liquid discharged. Next, when the lid body 4 is pressed, the bellows part 2 is compressed,
An amount of liquid corresponding to the compressed volume is discharged to the outside through the outlet pipe 7. Thereafter, when the pressing force is released, outside air is sucked into the container body 3 through the outlet pipe 7 by the restoring force of the bellows part 2, and air at atmospheric pressure is sealed above the remaining liquid in the container body. ,
As long as the spacing is not changed, the compressed volume remains constant and therefore a constant amount of liquid can be repeatedly discharged.

If the separation interval is increased or decreased, the compressed volume, and hence the liquid discharge amount, is increased or decreased in accordance with the increased or decreased separation interval and is set to a new constant value.

〔Example〕

An embodiment of the present invention will be described with reference to the drawings. In the example shown in FIG. A truncated cone-shaped lid 4 is rotatably fitted onto the upper end of a container body 3 formed by a retractable bellows portion 2, thereby forming a variable quantity discharge container for liquid. .

The upper end of this container body 3 is an opening 5 that can be opened almost entirely, but this opening 5 is sealed by a lid 4. The lid body 4 includes a discharge pipe 7 having a discharge port 6 for the liquid contained in the container body 3, a liquid discharge nozzle 8 communicating with the discharge pipe 7, and a protrusion 9 facing the cylindrical part 1. It is arranged. The cylindrical portion 1 is cylindrical and has a stepped portion 10 formed by an inclined surface along its outer circumference.

The step 10 and the protrusion 9 are spaced apart from each other so that when the lid body 4 is pressed to compress the bellows part 2, the protrusion 9 comes into contact with the slope of the step 10 and cannot be compressed any further. has been done.

That is, FIG. 1 shows the free state of the bellows part 2 without applying any pressing force to the lid body 4, and the distance between the lower end of the protrusion 9 and (the inclined surface of) the step part 10 is the same as that of the step part 10. The bellows portion 2 can be compressed over the entire range (the entire circumference of the cylindrical portion 1).

Furthermore, a locking mechanism (not shown) is provided to prevent the lid 4 from rotating relative to the container body 3 when pressed from above. Note that the discharge nozzle 8 has a shape that allows a cap (not shown) to be attached to and detached from the discharge nozzle 8.

Next, to explain the operation of this embodiment, when storing liquid in the container body 3, the lid 4 is removed and the liquid is stored up to the upper end of the cylindrical portion 1, and then the lid 4, and in order to repeatedly discharge a certain amount of liquid, keep the container upright and rotate the lid 4 relative to the container body 3 according to the set value of this certain amount, and remove the protrusion. After setting the distance between the part 9 and the stepped part 10 to a predetermined value, the lid 4 may be pressed to compress the bellows part 2 until the protruding part 9 comes into contact with the inclined surface of the stepped part 10.

That is, in the above discharge operation, since air at atmospheric pressure is sealed above the liquid, an amount of liquid corresponding to the compressed volume when compressing the bellows rises in the discharge pipe 7 and is discharged from the discharge nozzle 8. When the pressing operation is stopped, air is sucked into the container body 3 from the discharge nozzle 8 by the restoring force of the bellows part 2.
Air at atmospheric pressure is again filled in the upper part of the container body 3, and depending on the distance between the protrusion 9 and the step 10, the amount of discharged in each discharge operation is kept at a constant value. is set to

Next, a part of the stepped portion 10 in the example shown in FIG. 2 is made into a recessed portion 11 for locking. This recess 11 is formed so that it can be fitted with the protrusion 9 in the free state of the bellows part 2, where no pressing force is applied to the lid 4, so that the lid 4 cannot be pressed by mistake in the fitted state. The advantage is that there is no need to worry about liquid being drained even if there is a problem.

In the present invention, the cylindrical body having the stepped portion 10 can be engaged with the outer peripheral surface of the cylindrical portion 1 so as to be able to rotate relative to the protrusion 9.

[Effect of idea]

As described above, the variable quantity discharge container for liquids of the present invention has a simple structure and can repeatedly discharge a fixed amount of contents through simple operation, and this set discharge amount can be freely changed. It is extremely easy to use and highly practical.
