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 that can hold a fixed amount of liquid, and the measuring chamber is filled with an overflow type, a switching valve type, a type using air pressure/surface tension, etc. Various types of devices have been developed that allow a certain amount of liquid to be contained.

[Problem that the invention attempts to solve]

However, all of these conventional devices have complex structures, high costs, are difficult to operate, and furthermore, it is not possible to change the set discharge amount of the required liquid depending on the purpose of use. There were some shortcomings.

SUMMARY OF THE INVENTION In order to eliminate these conventional drawbacks, it is an object of the present invention to provide a variable discharge container for liquid that is simple in structure and operation, and in which the set discharge amount of liquid can be changed.

[Means for solving problems]

The present invention comprises a container body 3 consisting of a cylindrical part 1, an expandable spiral bellows part 2 connected to the upper part of the cylindrical part 1, and an outlet pipe 9 communicating with the inside of the container body. the discharge nozzle 10 connected to the bellows part 2;
A discharge container having a pump function is constructed by the lid body 4 having a threaded engagement member 6 formed thereon, and the amount by which the threaded engagement member 6 is engaged with the bellows portion 2 can be increased or decreased. This is a variable quantity discharge container for liquids, which is characterized by:

[Effect]

In this container, by increasing (reducing) the amount of screwing of the lid body into the bellows part, the width of expansion and contraction of the bellows part due to the pressing force is reduced (increased), and the set value of the liquid discharge amount of this container is Decrease (increase). That is, the discharge amount can be set to a desired value depending on the amount of screwing of the lid body into the bellows part.

〔Example〕

An example of the present invention will be described based on the drawings.
In the example shown in Fig. 1, there is a cylindrical part 1 that does not easily deform even when external force is applied, and a right-handed screw type spiral part that has restorability that can return to its original shape by itself and can be easily contracted by external force. A container main body 3 is formed by the shaped bellows part 2, and a lid 4 is detachably attached to the container main body 3, thereby forming a variable quantity discharge container for liquid.

An opening 2 ₁ is formed at the upper end of the bellows portion 2 and can be opened almost entirely, and a cylindrical portion 5 is provided below the opening 2 ₁ . The lid body 4 includes a threaded member 6 having a plurality of threads formed on its inner circumferential surface and screwed onto the outer circumferential surface of the bellows portion 2, and a cylindrical member fitted onto the inner circumferential surface of the cylindrical portion 5. part 7 and the container body 3
It comprises a discharge pipe 9 having a discharge port 8 for the liquid contained therein, and a liquid discharge nozzle 10 communicating with the discharge pipe 9.

Therefore, when the lid body 4 is rotated clockwise, the screw member 6 is screwed in along the bellows part 2 and moves toward the cylindrical part 1, but at the same time, the cylindrical part 7 is rotated against the inner surface of the cylindrical part 5. On the other hand, it slides down while rotating, and can be removed from the container body 3 by rotating counterclockwise.

The threaded member 6 is solid and is formed so that it is not easily deformed even when an external force is applied, so that the portion of the bellows portion 2 into which the threaded member 6 is threaded is a part of the lid. Even if the body 4 is pressed, it does not shrink. Therefore, the amount of screwing of the lid body 4 into the bellows part 2 is increased (decreased).
By doing so, the expansion/contraction width (vertical dimension) of the bellows portion 2 can be reduced (increased).

FIG. 1 shows a state in which the threads of the threaded member 6 are threaded over the entire threads of the bellows part 2, and therefore the width of expansion and contraction of the bellows part 2 is zero. .

Note that the discharge nozzle 10 may be provided in the cylindrical portion 1 and communicated with the outlet pipe 9.

Next, in the example shown in Fig. 2, the screwing member 6 is screwed onto the inner peripheral surface side of the bellows portion 2, and the structure is designed to prevent the contents from leaking from this screwed portion. It's summery.

Next, to explain the operation of the example shown in FIG. 1, when storing liquid in the container body 3, the liquid is stored up to the upper end position of the cylindrical part 1, and the lid body 4 is attached to the bellows part 2. Just screw it in along. When discharging a certain amount of liquid, the lid 4 may be screwed in along the bellows part 2 according to the set value of the certain amount, and then the lid 4 may be compressed and deformed to the reduction limit by pressing the lid 4. . Further, the lid 4 may be screwed to the lower end position of the bellows portion 2 (as shown in FIG. 1) when not in use, and then unscrewed when in use.

That is, in the above-mentioned discharge operation, a small pressing and compressing width of the bellows part 2 is defined by the interposition of the threaded member 6, and since air at atmospheric pressure is sealed above the liquid, the narrowing width corresponds to the above-mentioned reduced width. An amount of liquid corresponding to the amount of air is discharged from the discharge nozzle 10 via the outlet pipe 9, and when the above-mentioned pressing force is released, the bellows part 2 attempts to return to the state before compression due to its restoring force, and as a result, the discharge nozzle Air is sucked into the container body 3 from 10, and atmospheric pressure air is again sealed above the remaining liquid. If the same lid pressing operation as described above is performed in this state, the contents will be discharged in the same manner, but the amount of this discharge will be equal to the amount discharged by the first operation. Then, by the same operation thereafter, a fixed amount of discharge can be obtained each time, and the set value of the discharge amount can be increased (decreased) in accordance with the expansion/contraction range of the bellows portion 2 (smaller).

[Effect of idea]

As mentioned above, the variable quantity discharge container for liquid of the present invention has a simple structure and is easy to operate.
A certain amount of contents can be repeatedly discharged,
Moreover, the set discharge amount can be changed freely, making it extremely easy to use and highly practical.
