Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a metered dispensing container from which a fixed amount of a liquid contained in a container can be taken out at a time.

[Prior art] Liquid beverages, medicines, detergents, etc. contained in containers.
2. Description of the Related Art A metering dispensing container that is capable of measuring and dispensing chemical products in fixed amounts is known as disclosed in Japanese Utility Model Application Publication No. 80763/1983. This fixed-dose dispensing container is constructed by fitting a cup body with a measuring chamber inside into the mouth and neck of a soft container body, and providing a suction passage with a suction pipe vertically installed on the bottom wall of the cup body. This suction passage is equipped with a check valve that opens toward the measuring chamber, and a passage hole with a vertical pipe is provided in the peripheral wall of the cup body. The check valve is opened to allow the liquid to flow out from the suction pipe and fill the measuring chamber, and then the container body is released and as it is restored, the excess liquid in the measuring chamber is sucked into the container body through the passage hole and the pipe. After refluxing, the container is tilted to take out a predetermined amount of liquid that has filled the measuring chamber.

[Problem to be solved by the invention] However, in the metered dispensing container presented in the above-mentioned publication, when the liquid in the container flows out and fills the measuring chamber, the check valve closes inside the measuring chamber in the upright state. However, when the container is tilted to take out the liquid in the measuring chamber, it opens as the liquid in the measuring chamber is poured out. On the other hand, since the passage hole remains open, air flows into the container, causing excess liquid to flow into the measuring chamber, making accurate measurement impossible. It is noticeable when

The present invention was developed in order to solve these problems, and the purpose is to provide a quantitative dispensing container that is not only easy to handle, but also capable of accurately dispensing a fixed amount of liquid. That is.

[Means for Solving the Problems] In the present invention, a cup body with an open top is tightly fitted into the mouth of a container body having squeeze properties,
The inside of the cup body is divided into a pouring chamber and a reflux chamber by a partition wall having a predetermined height lower than the circumferential side wall, and an outlet is opened in the bottom wall of the cup body on the side of the pouring chamber. At the same time, this outlet is provided with a check valve that opens toward the pouring chamber, and
A reflux port is opened in the bottom wall on the reflux chamber side, and this reflux port is provided with a check valve that opens toward the container body. A means for solving the above problem is provided by a configuration in which a liquid passage is connected to the outlet and has a restriction near the upper end.

[Operation] The container body is squeezed to increase the internal pressure of the container body, and the liquid substance in the container body is caused to flow out from the liquid passage into the cup body until it exceeds the partition wall. Next, when the compression is released and the container body is restored, the check valve at the reflux port is opened and the check valve at the outlet is closed, so that the liquid above the partition wall and the reflux flow. The liquid in the chamber is returned to the container body, and a predetermined amount of liquid is stored only in the pouring chamber within the cup. Moreover, the liquid in the liquid passage is returned to the container body as the internal pressure of the container body decreases, and does not remain between the restrictor and the check valve provided near the upper end.

Then, by tilting or inverting the container body, a predetermined amount of liquid stored in the pouring chamber can be taken out. At this time, the check valve at the outflow port may open, but since the liquid passage is equipped with a restriction and the check valve at the return port is closed, the liquid does not pass through the restriction. There is almost no leakage into the pouring chamber.

[Example] Next, an example of the present invention will be described with reference to the drawings.

The drawing shows an embodiment of the present invention, in which a container body 1 having squeeze properties made of an elastic material such as a soft synthetic resin has a top open opening made of a hard material such as a hard synthetic resin at the mouth part. The cup body 2 is tightly fitted. This cup body 2 has an internal partition wall 22 with a predetermined height lower than the circumferential wall 21, and a spouting chamber 3.
and a reflux chamber 4, and a bottom wall 23 on the side of the pouring chamber 3.
An outflow port 31 equipped with a cantilever check valve 51 formed by providing a U-shaped notch in a flat plate that opens toward the pouring chamber 3 is open, and a A reflux port 41 is open, which is provided with a check valve 52 that opens toward the container body 1, which is formed by providing a cross-shaped cut in a curved plate. Further, a tubular liquid passage 6 is provided in the container body 1, the lower end 61 of which reaches near the bottom 11, the upper end 62 of which is connected to the outlet 31, and has a throttle 7 at the upper end.

In the drawings, reference numeral 8 is a lid that is placed over the opening of the cup body 2.

In this embodiment having such a configuration, the liquid substance 9 is contained in the container body 1. In order to take out a predetermined amount of the liquid substance 9, first, the lid 8 is removed and the container body 1, which is stood upright, is squeezed between fingers to increase the internal pressure. Then, the liquid substance 9 passes through the liquid passage 6 having the throttle 7, opens the check valve 51 provided at the outlet 31, and flows out into the pouring chamber 3. At this time, the liquid 9 is allowed to flow out over the partition wall 22 until it overflows into the reflux chamber 4, thereby filling the cup body 2 with a predetermined amount of the liquid 9. Next, when the compression of the container body 1 is released, the container body 1 expands and recovers due to its own elastic force, and the check valve 52 provided at the reflux port 41 opens due to the decrease in the internal pressure of the container body 1 at that time. The liquid material 9 above the partition wall 22 and the liquid material 9 in the reflux chamber 4 are returned into the container body 1.
Further, since the check valve 51 provided at the outflow port is in a closed state, a certain amount of liquid 9 is stored only in the spouting chamber 3 within the cup body 2. Furthermore,
The liquid 9 in the liquid passage 6 is returned to the container body 1 as the internal pressure of the container body 1 decreases, and does not remain between the throttle 7 and the check valve 51 provided at least near the upper end.

Then, when the container body 1 is tilted or turned upside down,
A certain amount of liquid material 9 stored in the pouring chamber 3 can be taken out. At this time, the check valve 51 provided at the outlet 31 may open, but the liquid passage 6
The small diameter orifice 7 provided in the container body 1 acts as an extremely large resistance against the liquid material 9 having viscosity and surface tension, and the check valve 52 of the reflux port 41 is closed. Since there is no air replacement, there is almost no possibility that the liquid 9 in the container body 1 will pass through the throttle 7 and flow out into the pouring chamber 3.
Extremely accurate weighing is possible.

In this embodiment, the check valves 51 and 52 are made of a flexible material such as a rubber material or a soft synthetic resin material, and are configured to maintain the valve closed state by their own elastic force, but other configurations may also be used. good.

[Effects of the invention] According to the invention having the above configuration, the liquid substance inside the container body is filled into the pouring chamber while the upright container body is squeezed and visually observed, and the squeeze is released to restore the container body. A fixed amount of liquid can be measured with a simple operation. Further, when the container body is tilted or turned upside down and taken out, there is no need to worry that excess liquid other than the measured amount will flow out, and a fixed amount can be taken out accurately.
