Description

[Detailed description of the invention] The present invention is a variable metered discharge stopper for liquids, specifically, a device that allows a fixed amount of liquid contained in a bottle to be discharged and also allows the fixed amount to be changed. This invention relates to a variable-type fixed-rate discharge plug for liquids.

When using various liquids such as mouthwash, toothpaste, conch juice, hair wash, etc. stored in a bottle, it is convenient to be able to take out only a certain amount depending on the purpose of use. A liquid metering discharge stopper or container that takes out only a certain amount of liquid inside has a measuring chamber that allows a certain amount of liquid to enter, and this measuring chamber has an overflow set,
Various types of devices have been developed that allow a fixed amount of liquid to be filled using a switching valve type, a type that uses air pressure or surface tension, etc., but all of these have complicated structures, are expensive, difficult to operate, and However, there are drawbacks such as a fixed amount, that is, a set amount of liquid to be discharged that cannot be changed depending on the purpose of use.

For example, the one described in Japanese Utility Model Application Publication No. 53-68449 was known.

This is a cylindrical body with a partially opened upper end (which serves as a discharge port) and a fully opened lower end, with a dogleg-shaped member (bottom wall and inner wall of the liquid flow path) and a single-shaped member (liquid outlet) inside. The tip of the dogleg-shaped member is located above the tip of the letter-shaped member, so that a certain amount of liquid accumulates inside the stopper when the container is inverted. That is what it is.

However, a stopper with such a structure does not have a hole for air-liquid exchange, and when the container is turned upside down, air enters the container from the outlet and makes a gurgling noise, causing the liquid level to rise into the liquid chamber.
In some cases, there was a risk that liquid might leak from the outlet when the device was turned upside down.

Even if one tries to measure the liquid by extending the single-shaped member of the stopper straight and attaching a slide plate to the tip thereof and sliding the slide plate in a direction approaching the container, it is difficult to measure the liquid accurately.

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

Hereinafter, the present invention will be explained with reference to illustrated embodiments.

In the first embodiment shown in FIGS. 1a, b to 4, at least the lower part is closed and surrounded by the peripheral wall part 2 to form a measuring chamber 3, and the upper part is for discharging the measured liquid. The stopper body 1 in which the discharge hole 4 is formed is attached to the mouth part 30 of the bottle 20.

In this embodiment, the stopper main body 1 is formed in a cylindrical shape, and the bottom wall portion 5 is used to close the lower part, but it may also be in the shape of an inverted cone with a pointed lower part or various other shapes. In short, it is sufficient that the metering chamber 3 is closed so that the metered liquid can be stored in the metering chamber 3 when the bottle 1 is erected.

Further, in this embodiment, a clay wall portion 6 is formed in a part of the upper part of the stopper body 1, and the outer peripheral wall of this upper wall portion 6 is formed into a flange 6a for attaching to the mouth portion 30 of the bottle 20. ing.

From the central edge of the upper wall portion 6 facing this discharge hole 4 to the measuring chamber 3
Partition plate 7 inward and below the lower edge of elongated hole 8, which will be described later.
has been extended.

A long hole 8 is formed along the upper direction of the peripheral wall 2 of the plug body 1, and a control plate 9 is attached to the peripheral wall 2 so as to close the long hole 8 and to be slidable in the vertical direction.

A hole 10 is placed at a position corresponding to the elongated hole 8 of this control plate 9.
is drilled.

This hole 10 is moved along the long hole 8 as the control plate 9 slides.

Two inlet holes 11 are formed in the upper part of the peripheral wall 2 to allow the liquid in the casing 20 to flow into the metering chamber 3.

This inflow hole 11 and the above-mentioned hole 10 are each formed into a small hole, and the inflow hole 11 mainly functions to cause the liquid in the class 20 to flow into the measuring chamber 3, and the inflow hole 11 causes the air in the measuring chamber 3 to flow out into the class 20. The function is mainly carried out by the holes 10, and these inlet holes 11. The hole 10 allows smooth exchange of gas and liquid.
0 flows into the measuring chamber 3.

Of course, the hole 10 is set so that gas and liquid can be exchanged independently, but depending on the type of liquid, it is preferable that an inflow hole 11 is provided.

Alternatively, the hole 10 can be formed into a vertical hole of the same size as the elongated hole 8, as will be described later.

Next, to explain the operation of this first embodiment, first, the bottle 2
0 is turned upside down, the liquid in class 20 is flowed into the chamber surrounded by a part of the peripheral wall 2, the partition plate 7, and the earthen wall 6 in the measuring chamber 3 using the hole 10 and the inflow hole 11. let

When the bottle 20 is inverted, liquid flows from the soil wall 6 to the height of the hole 10.

Therefore, the position of this hole 10 determines the amount of liquid.

Thereafter, by standing the bottle 20 upright, the measured liquid is stored in a chamber including the bottom wall 5 and surrounded by the peripheral wall 6.

; Then, while tilting the bottle 20 toward the discharge hole 4 side, turn the bottle 20 again.
When the bottle 20 is turned upside down, the liquid stored in the measuring chamber 3 is discharged from the discharge hole 4, and the liquid in the bottle 20 flows into the measuring chamber 3 again in preparation for the next use.

In order to adjust the amount of liquid to be discharged, the height position of the hole 10 within the elongated hole 8 may be changed by sliding the control plate 9 up and down.

The chamber into which the liquid flows when standing upside down, that is, the room in the surrounding wall 3 surrounded by a part of the surrounding wall 2, the partition plate 7, and the earthen wall 6, is temporarily referred to as the When the chamber in which liquid is stored is the Y chamber, the maximum value of the liquid flowing into the X chamber (the first
As shown in the figure, when the hole 10 matches the lowest part of the elongated hole 8), the maximum amount that can be stored in the Y chamber (from the bottom wall 5 to the hole 10
If the amount is the same as or less than the amount (up to the position of ), it can be measured by the amount of inflow into the X chamber during the inverted position, as described above.

Therefore, as the hole 10 moves above the elongated hole 8 (upward when the bottle 20 is erected), the amount of liquid to be measured decreases.

On the other hand, if the amount of liquid flowing into the The liquid is stored up to the position of the hole 10, and the measurement can be adjusted by changing the height of the hole 10 from the bottom wall 5.

In the drawing, the liquid volume is determined by the height position of the hole 10 from the earthen wall part 6 when standing upside down, but the change in the height position of the hole 10 from the bottom wall part 5 when standing upright. It is easy to change the design to increase or decrease the weight.

For example, by increasing the distance between the earthen wall portion 6 and the inflow hole 11, it is possible to easily make the amount flowing into the X chamber exceed the amount stored up to the hole 10 in the Y chamber.

In addition, in order to make it easier to drain the liquid in class 20 to the end,
The inlet 11 may be formed very close to the earthen wall 6, or
The shape of the mouth part 30 of 0 may be made narrower at the upper end like a truncated cone.

In addition, when sliding the control plate 9 in the vertical direction to vary the amount of liquid stored in the measuring chamber 3, the scale corresponding to the amount of liquid discharged to the control plate 9 is set, for example, 10CC, 20C.
It will be easier to use if you adjust the size of the cylinder, such as C, 39cc, etc., or change the color.

Furthermore, the shape of the control board 9 can be changed in various ways, such as by providing a finger rest at the upper end, for example, to make it easier to operate.

Further, in the above embodiment, the control plate 9 closes the elongated hole 8 formed in the peripheral wall 2 of the measuring chamber 3, and
Although the hole 10 is moved relative to the elongated hole 8 by forming a hole in the peripheral wall 2 of the measuring chamber 3 into which the control plate 9 is inserted, the shape is not limited to this.

For example, the control plate 9 is provided so as to be in close contact with the inside or outside of the peripheral wall portion 2 and to be slidable in the vertical direction, so that the hole 10 formed in the control plate 9 can freely slide in the elongated hole 8. Of course, any structure may be used as long as the liquid does not leak from the close contact portion between the control plate 9 and the peripheral wall portion 2.

Figures 5a and 5b show a second embodiment of the present invention, in which the holes 10 formed in the control plate 9 in Figures 1 to 4 are formed with their longitudinal directions perpendicular, as shown in Figure 5. At the same time, the inflow hole 11 formed in the upper part of the measuring chamber 3 in Figs. 1 to 4 is omitted, and the other structure is as shown in Figs. 1 to 4. Same as shown.

In this way, the hole 10 is shaped into an elongated vertical hole; thereby, when the bottle 20 is turned upside down and liquid is allowed to flow into the measuring chamber 3, a part of this vertical hole becomes the aforementioned inflow hole 1.
It also plays the role of 1 to cause liquid to flow into the measuring chamber 3, and can discharge a desired fixed amount of liquid by the same action as described above.

In this case, the amount of liquid to be discharged is determined by the same principle as described above, but the amount of liquid is determined in proportion to the distance from the bottom wall 5 of the measuring chamber 3 to the lowest position of the vertically long hole 10. Further, the amount of liquid to be discharged can be set to a desired amount by moving the control plate 9 in the vertical direction and adjusting the position of the hole 10, as described above.

FIG. 6 shows the third embodiment of the present invention, and shows the first embodiment.
The earthen wall portion 6 and partition plate 7 of the embodiment are not provided, and substantially the entire upper part of the plug body 1 is opened to form the discharge hole 4.

A removable cap 12 is attached to this discharge hole 4.

In this embodiment, the bottle 20 is turned upside down with the cap 12 attached to allow the liquid to flow into the measuring chamber 3, and then the bottle 20 is turned upright again so that the liquid flows from the bottom wall 5 to the position of the hole 10 or from the cap 12.
The liquid is stored from to the position of the hole 10, and then the cap 1
It has an extremely simple structure in that it can be discharged from the discharge hole 4 by removing the tube 2.

Instead of the key 12, the discharge hole 4 may be closed with a finger when the bottle 20 is turned upside down.

At this time, until the liquid stored in the measuring chamber 3 is discharged from the discharge hole 4, the liquid in the bottle 20 does not flow into the measuring chamber 3 from the inlet hole 11.
Although it is desirable to devise the shape of the volume chamber 3, if the bottle 20 is tilted so that the stopper body 1 shown in FIG. If it does not reach the inflow hole 11, it will not reach the intended purpose.

Although the inflow hole 11 is not shown in FIG. 6, it is of course formed in the same manner as in the first embodiment described above.

As explained above, according to the present invention, the hole of the control plate is brought into close contact with the elongated hole formed in the peripheral wall of the plug body, and the position of the hole is adjusted by sliding it in the vertical direction. Since the amount of liquid discharged can be changed, the amount of liquid can be changed freely depending on the purpose of use, and the structure and operation are simple.

By being able to vary the amount of liquid in this way,
The amount of liquid can be set to the optimum amount depending on the purpose of use, and the liquid can be used economically and effectively without being too large or too small.

In addition, air-liquid exchange occurs smoothly at the part where the elongated hole of the stopper body and the hole of the control plate match, and accurate metering is possible without air entering the liquid level and causing the liquid level to become a liquid chamber. can.

Furthermore, since the control plate slides inside the circumferential wall of the stopper body, the sliding portion of the control plate provides good sealing when the bottle is inverted, and there is no risk of inaccurate metering.
