Description

[Detailed description of the invention] [Industrial application field] This invention relates to a metered dispensing container that dispenses a fixed amount of liquid by squeezing the container body, and is suitable for liquids such as medicines, detergents, and cosmetics. Used for containers.

[Conventional technology and its problems]

Dispensing containers for measuring and dispensing liquid in fixed amounts are well known and come in a variety of mechanisms.
The container body is made of an elastic material, and by pressurizing it by squeezing, the liquid content is pushed out from the liquid guide pipe into the measuring chamber at the mouth of the container body, and then the container is knocked down to take out a certain amount of liquid content from the measuring chamber. This is also known as one of them.

In this type of metered dispensing container, the upper end of the liquid guide pipe projects into the measuring chamber and opens, and the height of the opening allows the extruded content to be measured to a certain amount. If the container is left open, when the container is tipped over, the liquid inside the liquid conduit and the container body will also flow out and be taken out. Therefore, it is possible to attach a closing button to a cap with a spout, pull it to open the opening, and push it to close the opening (see Japanese Utility Model Publication No. 47-4790). It has been considered to screw a cap onto the mouth of a container, loosen it to open the opening, and tighten it to close the opening (see Japanese Utility Model Application No. 163456/1983).

However, these have a movable part for opening and closing the opening of the liquid conduit to the measuring chamber, which not only makes the structure complicated, but also makes operation difficult as the opening must be opened and closed each time the liquid is taken out. It is troublesome and extremely troublesome when used repeatedly. In addition, if the operation is incomplete, the opening may not be opened sufficiently, making it difficult to push out the liquid inside the metering chamber, or the opening may not be completely closed, causing the inconvenience that the liquid inside the guide tube may be taken out together with the opening.

The present invention has a structure in which the opening of the guide tube to the measuring chamber is opened and closed each time for dispensing a fixed amount, but the structure is complicated, the operation is troublesome, and the reliability is lacking. The object of the present invention is to provide a quantitative dispensing container that has a simple structure, is easy to handle, and is reliable.

(Means for Solving the Problems) The present invention provides a measuring chamber with an open top surface provided at the mouth of a container body made of an elastic material, and a plug having a spout at the top and covering the top surface of the measuring chamber. a liquid receiving chamber provided inside the stopper body, the lower surface of which communicates with the upper part of the measuring chamber; and a liquid receiving chamber that opens toward the liquid receiving chamber at the upper position of the measuring chamber, The provision of a liquid guiding pipe reaching the bottom is a means for solving the above-mentioned problems.

[Effect]

When the container body is squeezed to increase the internal pressure, the liquid content is pushed out through the liquid guide pipe toward the liquid receiving chamber and enters the measuring chamber from the lower surface thereof. When the container body is released, the liquid content becomes at the same level as the upper end opening of the liquid guide pipe, and a certain amount of liquid remains in the measuring chamber. Next, when the entire container is turned upside down, a certain amount of liquid in the measuring chamber is taken out from the spout of the stopper, and the liquid contained in the liquid guide tube flows into the liquid receiving chamber and is not taken out from the spout.

[Embodiment 1] A first embodiment of the present invention will be explained based on FIGS. 1 to 6. A container body 1 made of an elastic material such as a soft synthetic resin has a screw 2 on the outer peripheral surface. A plug body 5 is airtightly fixed to the mouth part 3, and

A lower part of a liquid receiving chamber 17 arranged concentrically with the rising part 9 is fixed to the center of the bottom wall 13. The liquid receiving chamber 17 has a plurality of communication holes 18 in its lower part communicating with the measuring chamber 11, and has an outlet 14 opening in the center.

In this embodiment configured in this way, when the container body is pressed in the direction of arrow A in an almost upright state as shown in FIG. The liquid is pushed out into the liquid receiving chamber 17 and then enters the measuring chamber 11 through the communication hole 18 around the outlet 14. For example, the fourth
When the container body 1 is released when it reaches the position indicated by a-a in the figure, it expands and restores itself due to its own elastic force, and as the internal pressure decreases, the measuring chamber 11 and liquid receiving chamber 17
The liquid content flows back into the container body 1 from the outlet 14, and the liquid level in the metering chamber 11 drops to the edge of the outlet 14 indicated by bb (see FIG. 5). Next, the entire container is inverted, and if necessary, the container body 1 is squeezed to increase the internal pressure, and a certain amount of liquid in the measuring chamber 11 is taken out from the spout 10, and the liquid in the liquid guide pipe 15 is removed from the liquid receiver. It falls into the chamber 17 (see Figure 6). When you have finished taking out the liquid and returned to the upright position, the liquid receiving chamber 1
A part of the liquid contained in No. 7 enters the liquid guiding pipe 15, but a portion passes through the communication hole 18 and accumulates at the bottom of the measuring chamber 11, and is taken out together with the liquid pushed out from the container body 1 during the next use. Ru.

Incidentally, when not in use, a lid (not shown) is screwed onto the screw 2 to close the spout 10. In addition, the plug body 5

[Effect of idea]

According to the present invention, the measuring mechanism is composed of a measuring chamber, a liquid conduit opening at the top of the measuring chamber, and a liquid receiving chamber into which the liquid contained in the liquid conduit flows when the device is inverted. The structure is simple, and since no other operations are required except for squeezing and releasing the container body and inverting it, it is easy to handle even if it is used repeatedly. Furthermore, when the liquid guide tube is inverted, the liquid content in the liquid guide tube is received by the liquid receiving chamber and is not taken out from the spout, so a fixed amount of the liquid content can always be taken out with a simple operation of inverting the tube.
