Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a stopper structure for dispensing and distributing a liquid in a container, which is a liquid detergent or washing aid which does not require precise measurement.
It is used by mounting it on a container for liquids such as bath salts, fertilizers, shampoo / rinse and seasonings related to food.

[Conventional technology]

Liquid dispensing plugs are available in Japanese Utility Model Publication No. 38-18396,
It is shown in Japanese Utility Model Publication No. 47-25250. The plugs shown in these figures have three to three parts when actually manufactured.
There were four pieces, which were relatively easy to manufacture.

In the structure shown in Japanese Utility Model Publication No. 38-18396, by reversing the container, the liquid already in the metering chamber is discharged, and at the same time, the liquid in the container is surrounded by the metering chamber and the inner lid. Collect in. At this time, it is described that the ball valve closes the inlet b.

However, the air port has not been touched upon.In a squeeze plastic container, pressure is applied to the container opening due to the weight of the liquid just by turning the container upside down, so the liquid will flow directly from the air port to the metering chamber. It is obvious that it flows out, and it cannot be said that it has a metering property for a bottle having a squeeze property.

In addition, in the case of Japanese Utility Model Publication No. 47-25250, by reversing the container, the liquid already in the right chamber is discharged, and at the same time, the liquid in the container passes through the flow hole, the empty chamber, and the valve hole, and the left chamber. Enter At this time, air is sent into the container through the flow control pipe, and if the lower end of the flow control pipe is blocked by the liquid, the supply of the liquid is stopped.

However, this structure can be used only when the container is hard and has no squeeze property.In a container with squeeze property, the container squeezes due to the weight of the liquid, so the supply does not stop and the right side from the opening. It is directly discharged through the chamber.

Also, assuming that it stopped in a hard container and returning the container to its original vertical state, the liquid in the left chamber will flow into the right chamber through the opening, but there must be air circulation between the left chamber and the right chamber. For example, the liquid in the left chamber cannot move to the right chamber at the opening that is large enough for the plug to be attached to the container opening.

Therefore, the above-mentioned prior art has a problem that a plastic container having a squeeze property cannot be used due to unstable metering due to liquid leakage, and liquid and air are moved separately when moving in a space where liquid is closed. There is a problem that it will not function if it is not possible.

[Problems to be solved by the device]

An object of the present invention is to provide a metering plug body which has a structure in which the liquid and the air can be separately moved in a space where the liquid is closed even if the container has a squeeze property, and there is no liquid leakage and the weighing is stable. It is to be.

[Means for Solving the Problems]

According to the present invention, a support member having an air port is continuously provided inside a discharge port of a main body for discharging a measured liquid, and a reverse funnel-shaped passage tube is vertically moved within the support member by a predetermined distance. I made it possible to move. The small-diameter portion having a diameter larger than the discharge port of the passage tube was set to the discharge port side, and the funnel-shaped part was set to the measuring chamber side. The measuring chamber has a cup-shaped measuring portion having a diameter smaller than the diameter of the funnel portion of the passage tube, and a cylindrical wall larger than the large diameter of the passage tube is connected to the side of the measuring portion through the bottom wall. This cylindrical wall can be moved up and down a specific distance by using a plurality of rail members provided on the outer wall connected to the main body as a guide, and the lower end of the movement is provided at the lower end of the rail member. It is stopped by a stopper, and the upper end is a stopper having a structure in which the bottom wall of the measuring chamber pushes up the passage tube and moves the distance until the passage tube hits the lower end of the discharge port.

[Operation] With the above structure, when the container is turned upside down, the measuring chamber is pushed forward by the liquid in the container, and at the same time, the discharge port and the passage cylinder located at the center of the measuring chamber are also moved forward to move the discharge port. It comes into close contact with the end face of the lower end and stops. Therefore, the measuring chamber communicates with the outside air through the passage cylinder and the discharge port, and is shut off from the inside of the container.

On the other hand, even if the container is squeezed or squeezed by hand, the force only pressurizes the measuring chamber and the passage tube to the discharge port side, the adhesion becomes stronger and the liquid in the container is directly discharged. There is no such thing.

Then, when the container is returned to the vertical state, the passage cylinder is lowered by the distance that the air port is opened, and the metering chamber is also lowered by the distance that the inflow port is opened, and the two holes of the inflow port below the upper air port enable the movement of the liquid. To do.

That is, in the present invention, when the content liquid is discharged, the air passage is closed by the forward movement of the passage cylinder, and the measuring chamber is further moved forward to block the measuring chamber and the inside of the container. Further, when returned to the vertical position (during measurement), the passage cylinder and the measuring chamber retreat to open the air port, and the content liquid accumulated in the preliminary chamber smoothly moves to the measuring section together with the air flowing in from the air port.

The inverted funnel of the passage tube is used to reliably receive the liquid discharged from the measuring chamber so as not to spill it and send it to the discharge port, and when it is inverted, it contacts the bottom wall and blocks the passage to the auxiliary chamber. It has a function.

〔Example〕

 Examples will be described with reference to the drawings.

FIG. 1 is a sectional view of a liquid measuring plug according to the present invention.
The figure is a cross-sectional view showing a state in which the stopper is attached to the container opening and the container is tilted.

As shown in FIG. 1, the present invention comprises a main body (1), a passage tube (2) and a measuring chamber (3).

The main body part (1) has a cylindrical convex wall (6) which forms a discharge port (5) at the center of the upper lid part (4) on the disc on the outside, and a cylindrical convex wall (6) on the inside thereof. A support member (7) having a larger diameter is continuously provided, and 1 from the lower end of the discharge port (5).
Notches are provided at ~ 2 mm to form a plurality of air ports (8), and a convex portion (9) is provided at the lower end.

Further, the outer wall cylinder (1
0) are continuously provided, and a plurality of rail members (11) are vertically provided continuously along the entire circumference inside thereof, and a stopper portion (12) is provided at a lower end of a part of the rail member.

The passage tube (2) has an inverted funnel shape, the small diameter portion (13A) is on the upper side, the funnel-shaped portion (13B) is on the lower side, and a concave portion (13C) having a specific width is provided. The convex portion (9) of the supporting member (7) is loosely set in the supporting member (7) so as to move within the range of the concave portion (13C).

The measuring chamber (3) has a cup shape having a diameter smaller than the diameter of the funnel-shaped portion (13B), and the bottom wall (14) is located on the side of the measuring portion (20).
A cylindrical wall (15), which is a cylinder having a larger diameter, of the funnel-shaped portion (13b) is continuously provided upward through the outer surface of the funnel-shaped portion (13b) while being guided by the rail member (11) of the main body portion (1). It is set in the main body (1) so as to be movable.

A preliminary chamber (16) is formed by being surrounded by the cylindrical wall (15), the passage cylinder (2) and the upper lid portion (4).

Here, the cylindrical wall (15) is provided with a plurality of small holes (19) below the upper end of the rising wall (18), and the preliminary chamber (16) is filled with the liquid at a height higher than the rising wall (18). Do not collect.

When the plug is placed vertically as shown in Fig. 1, the passage tube (2) stops at the position where the convex portion (9) hits the upper end of the concave portion (13C) with respect to the main body portion (1). , An air port (8) provided in the support member (7) is provided at the upper end of the passage tube (2).
It is opened 3 mm.

Further, the weighing chamber (3) has a rail member (1
The bottom wall (14) is in contact with the stopper portion (12) at the lower end of 1), and at this time, a flow of about 3 to 6 mm flows between the lower end of the passage tube (2) and the bottom wall (14). Entrance (1
7) is formed.

The size of this inlet is adjusted by the viscosity of the liquid.

Further, by providing a rising wall (18) upward at the inner end of the bottom wall (14) of the measuring chamber (3), the liquid in the measuring chamber (3) is discharged from the inlet (17). It is possible to reliably discharge without returning, and the width of the opening of the inflow port (17) is preferably such that the liquid does not return at the height of the rising wall (18) because the viscosity of the liquid is high. It can be made larger.

Further, since the small hole (19) is provided in the cylindrical wall (15), liquid does not accumulate in the preliminary chamber (16) more than the rising wall (18), so the measuring unit (20)
You can measure with certainty.

When the container is tilted, the measuring chamber (3) is moved by being pushed by the liquid in the container as shown in FIG. 2, and the passage tube (2) is also moved at the same time, and stops against the upper lid part (4). That is, the bottom wall (14) of the measuring chamber (3) and the lower end of the passage tube (2) on the funnel-shaped portion (13B) side are in close contact with each other to close the inflow port (17), and the small diameter portion of the passage tube (2). The tip of (13A) and the upper lid (4) are in close contact with each other to close the air port (8), and the inside of the measuring chamber (3), the inside of the passage tube (2) and the discharge port (5) are integrated. The inside of the container is shut off.

When the container is tilted as shown in FIG. 2, the liquid in the container enters the preliminary chamber (16) through the gap between the outer wall cylinder (10) having the rail member (11) and the cylindrical wall (15) all around. The air in the preliminary chamber (16) escapes into the container through the gap and the small hole (19) located on the upper side.

In addition, even if the container is squeezed in this state and is pressurized by hand, the lower end of the discharge port (6) and the upper end of the small diameter portion (13A), and the lower end of the funnel-shaped portion (13B) and the bottom wall ( Only the two contact parts of 14) are strongly pressed and no liquid leakage occurs.

Next, when the container is returned to the vertical state, the convex portion (9) of the support member (7) of the passage tube (2) is concave as shown in FIG.
It descends until it hits the upper end of (13C), and the air port (8) opens. At the same time, the measuring chamber (3) descends until it comes into contact with the bottom wall (14) and the stopper portion (12), and then the inflow port (1).
7) is opened to allow the liquid to flow in.

[Effect of device]

Since the present invention is configured as described above, it has the following effects.

At the time of discharge, the measuring chamber, the inside of the passage tube, and the discharge port are integrally connected and shut off from the inside of the container.The higher the pressure inside the container, the stronger the shutoff. Even if it is pressurized with, it does not leak, so it has excellent meterability. In addition, in the vertical state, the structure is such that the air port is opened above the closed preliminary chamber and the inflow port is opened downward, and since the cylindrical wall forming the preliminary chamber and the measuring chamber are integrated, the movement of the liquid is performed reliably and is reliable. It is highly practical, has a simple structure and is highly practical.
