Description

[Detailed Description of the Invention] The present invention mainly relates to a quantitative discharge device that measures and takes out a fixed amount of powder or granules.

Conventionally, various structures have been proposed for quantitative dispensing devices that take out fixed amounts of liquid materials, but powder and granular materials have completely different fluidity from liquid materials, and they are the same as quantitative dispensing containers for liquid materials. Containers with this structure have problems such as considerable dispersion in metering or particles stagnation in the middle, impairing normal metering or discharging functions.

Therefore, a measuring chamber is provided at the bottom for the purpose of quantitatively discharging powder and granules, and by placing the discharge pipe upside down with this measuring chamber, the powder and granules filled in the measuring chamber are discharged through the discharge pipe. For example, a container configured to allow the holder to be opened is disclosed in Japanese Utility Model Application Publication No. 51-104845. This container has a measuring chamber part and a discharge pipe part that are rotatable with respect to each other, and is designed to measure a certain amount by taking advantage of the natural fall of powder and granules into the measuring chamber. .

However, the lower edge of the discharge pipe that rotates and aligns itself above the measuring chamber is not structured so that the bottom edge of the container comes into close contact with the bottom wall of the container. In addition to not being able to accurately measure a certain amount, the discharge pipe rotates together with the main body, and the lower part of the main body and the bottom wall containing the measuring chamber rotate with respect to each other, making sealing a problem. It is unsuitable for measuring and discharging objects.

The present invention solves these problems and provides a quantitative discharge container that can always measure a certain amount accurately and discharge smoothly, and has a structure that is suitable for not only powdery materials but also liquid materials. .

That is, the quantitative discharge container according to the present invention includes a main body provided with a measuring chamber below the bottom wall whose upper surface is open to the bottom wall, a lid rotatably attached to the upper end of the main body, and a lid that is rotatably attached to the upper end of the main body. a discharge pipe which is eccentrically provided from the center and firmly penetrates through the discharge pipe; a guide pipe which is attached to the lower part of the discharge pipe so as to be movable up and down and whose lower end edge overlaps the opening edge of the measuring chamber; and the discharge pipe and the guide pipe. An elastic material is inserted between the bottom wall and the bottom wall to keep the lower edge in close contact with the top surface of the bottom wall at all times.

An example of the present invention will be explained below with reference to the drawings.
A main body 3 having a cylindrical peripheral wall 1 and a bottom wall 2 with an open upper surface, and a lid 6 having a skirt wall 4 and a top wall 5 form an annular ring formed on the outer peripheral surface of the upper end of the peripheral wall 1. A guide protrusion 8 formed on the inner peripheral surface of the skirt wall 4 in the guide groove 7
are connected by fitting together, and the lid 6 rotates while airtightly covering the upper surface of the main body 3.

On the top wall 5 of the lid 6, a discharge pipe 9 extending in the rigid direction eccentrically from the center of rotation is integrally formed and protrudes vertically, and a cap 1 is attached to the upper end of the discharge pipe 9.
It is overlaid with 0. An insertion part 11 with a slightly larger diameter is formed at the lower end of the discharge pipe 9, and a fitting part 13 at the upper part of the guide pipe 12 is inserted into the insertion part 11, and a rubber or synthetic material is inserted between these parts. An elastic member 14 made of a resin O-ring is inserted. The guide pipe 12 is movable up and down with respect to the discharge pipe 9, and its lower end edge 15 is always in contact with the upper surface of the bottom wall 2 due to the elasticity of the elastic member 14.

A stop 16 and a metering chamber 17 are provided on the bottom wall 2 in appropriate phases so as to be located on the circle in which the guide tube 12 moves when the lid 6 is rotated. Stop part 16
is formed by a low circular convex portion that fits almost tightly into the lower end opening of the guide tube 12, and the measuring chamber 17 is formed below with its upper surface open to the bottom wall 2, and the opening edge of the open surface 18 19 is formed as a shallow recess into which the lower end edge 15 of the guide tube 12 is fitted and overlapped. In addition, the stop part 16 and the measuring chamber 17 are generally at an angle of 45 degrees.
They are arranged with a phase of 90 degrees, and they are formed at the lower part of the inclined bottom wall 2.

Incidentally, the peripheral wall 1 of the main body 3 is arranged so that the lid 6 is reciprocated at a predetermined angle between the stop part 16 and the measuring chamber 17.
An arcuate groove 20 is provided on the outer circumferential surface of the upper end of the
A protrusion 21 on the hem wall 4 of the lid 6 fits into this groove 20.

FIG. 3 shows a state in which the guide tube 12 is fitted into the stop part 16, and the contents accommodated in the main body 3 are transferred to the guide tube 1.
2, and since the measuring chamber 17 communicates with the inside of the main body 3, it is filled with the contents. When the lid 6 is rotated, the guide tube 12 comes off the stop part 16 and is attached to the bottom wall 2.
The lower end edge 15 slides on the upper surface of the measuring chamber 17, and the lower end edge 15 fits into the opening edge 19 of the measuring chamber 17, so that they overlap with each other. At this time, the fourth
As shown in the figure, the measuring chamber 17 communicates in a straight line with the guide pipe 12 and the passages 22, 23 of the discharge pipe 9, and at the same time is cut off from the inside of the main body 3. Therefore, by inverting the container, the measuring chamber 17 The contents enclosed in the container are discharged through the passages 22 and 23. When the container is erected and the lid 6 is rotated in the opposite direction, the contents fill the measuring chamber 17 again.

If the content is powder or granules, the guide tube 12 is connected to the measuring chamber 1.
7, the lower edge 15 scrapes off the powder along the open surface 18, allowing accurate measurement. In the case of liquid, when a part of the guide tube 12 overlaps with the measuring chamber 17, it will flow into the passage 21, so either form them into a small diameter or quickly rotate the lid 6 to change the lower edge 15 to the opening edge. It is necessary to consider ways to reduce variations in measurement by instantaneously overlapping the measurement chamber 19 or by momentarily opening the measurement chamber 17.

It goes without saying that a spring may be used instead of the O-ring as a means of applying an elastic force to the guide tube 12 to keep it in constant contact with the bottom wall 2, and a sign indicating the range in which the lid 6 is to be rotated back and forth may be provided. It may be provided on the main body 3 and the lid 6, and in this case, the stop portion 16 on the bottom wall 2 is unnecessary.

As described above, according to the present proposal, the measuring chamber is provided below the bottom wall of the main body and its upper surface is open to the bottom wall, so the measuring chamber is placed at the lowest point of the main body, and therefore the container can be properly erected. Even if there is no such thing, the contents will surely fill the measuring chamber by gravity and can be thoroughly measured and discharged. Then, a lid is rotatably attached to the upper end of the main body, a discharge pipe is provided firmly through the lid at a position eccentric from the center of rotation, and a guide pipe whose lower edge is in contact with the upper surface of the bottom wall is connected to the discharge pipe. The measuring chamber is attached to the bottom of the main body so that it can be moved vertically so that the lower edge overlaps the opening edge of the measuring chamber, so that the measuring chamber can be communicated with the inside of the main body and filled with contents by simply rotating the lid. Alternatively, it can be discharged by communicating with the guide tube, making handling operations extremely simple, and since the lid rotates at the top of the main body, it can be handled without worrying about the contents leaking from this part. In addition, the lower edge of the guide tube is always in close contact with the top surface of the bottom wall due to the elastic material, so even if there are dimensional errors or unevenness for positioning is provided on the top surface of the bottom wall, the guide tube will always be in close contact with the bottom wall. This eliminates the inconvenience of the contents entering the guide pipe or flowing out through the gap, causing variations in the discharge amount, and furthermore, since the measuring chamber and the outside of the container communicate linearly through the guide pipe and the discharge pipe. This allows the contents to be discharged smoothly.

In other words, according to the present invention, it is possible to always accurately and smoothly discharge a substantially constant amount of contents without causing the contents to stagnate in the middle and impair normal measuring and discharging functions. It is suitable for quantitative discharge of
