Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a stopper attached to an opening of a container for discharging a fixed amount of contents in the container by a simple operation.

<Prior Art> As a prior art, there is one disclosed in Japanese Utility Model Laid-Open No. 58-101133. That is, as shown in FIG. 3, a cylindrical wall 31 and an annular stopper continuously provided at the lower end of the cylindrical wall 31.
A fixed portion 33 composed of 32, a front lid portion 34 movable in the cylindrical wall 31, and a collar 35 at the other end provided below the front lid portion 34, an annular convex portion 36 in the specific (1), between them. It is a fixed amount plug body which is composed of a movable part 39 including a conduit having a small hole 37, and a rear plate 40 is movably attached between the flange 35 and the annular convex part 36 of the conduit 38.

<Problems to be Solved by the Invention> In the above-mentioned conventional metering plug body, the rear plate 40 closes the inlet f formed by the peripheral edge of the annular stopper 32 of the fixing portion 33 when the contents are discharged. By the way, when the container is tilted in order to discharge the contents in the container, if the content liquid is small, the content liquid moves abruptly in the container, and the movable plate 39 is pushed and the rear plate before the correct measurement is performed.
There was a problem that 40 blocked the inflow port f.

<Means for Solving the Problems> The present invention has a fixed portion in which an annular stopper is continuously provided at the lower end of a cylinder wall, and an inflow port is formed by the peripheral edge of the annular stopper, and an opening portion in the center. A movable part having an auxiliary wall on the periphery of the plate, and a conduit provided below the front plate opening part of the front lid part having an air suction hole in the front which is movable in the cylindrical wall; In a fixed amount plug body composed of a rear plug body portion continuously connected to the lower end of the conduit of the movable portion, a bottom plate having a small hole for covering the movable portion and the rear plug body on the outer surface of the cylinder wall,
Further, the metering plug body is characterized in that a cylinder body having an injection hole is attached to a side portion thereof.

<Operation> When the metering plug of the present invention is attached to the container opening and the container is tilted, the contents enter through the holes provided on the side of the cylinder,
The front lid advances toward the opening, and the contents flow into the measuring chamber formed by the front lid, the cylindrical wall, and the annular stopper. The front lid part continues to move forward, and the rear stopper body part connected to the lower end of the conduit moves together with the front lid part and contacts the annular stopper to completely shut off the measuring chamber from the inside of the container. The contents of are discharged.

The movable part is covered with a cylinder wall having a bottom plate, and the contents flow in only through the holes provided on the side parts of the cylinder, so that the movable part retains the contents even if the contents in the container become small. Since it is not pushed or tilted by a sudden movement, it can be weighed correctly.

<Example> As shown in FIG. 1, the fixed amount plug A of the present invention has a fixed portion 1
And a movable part 2, a rear plug body 3 and a cylinder body 4. The fixed part 1
In a container B, a fitting wall 5 fixed to the container B and an outer wall 6 forming a discharge port a are connected to a single cylinder wall 4 that communicates from the inside to the outside of the container B. The convex portion 21, the lower end thereof is provided with the annular stopper 7, and the upper end thereof is provided with the guide plate 8, and the peripheral edge of the annular stopper 7 forms the inflow port b. The movable portion 2 is a front lid portion 9 that moves inside the cylindrical wall 4.
A conduit 10 having a taper tapering downward is continuously provided on the front cover portion 9. The front lid portion 9 has an auxiliary wall 12 on the circumferential edge of a front plate 11.
The front plate 11 is provided with a continuous conduit at the center.
It has an intake port C which is an opening communicating with the conduction hole 13 inside 10, and a small hole x for air intake is formed in a part thereof. The rear plug body portion 3 is swingably connected to the lower end of the conduit 10 of the movable portion 2. Specifically, a stopper portion 14 is provided at the lower end of the conduit 10 and a lower end side portion thereof is provided. Two split grooves 15 facing each other are formed so that the stopper portion 14 can be easily opened. On the other hand, as the rear plug body portion 3, a spherical locking portion 16 which is locked inside the stopper portion 14 is located below the locking portion 16 and has a columnar neck portion having a length longer than the thickness of the stopper portion 14. A skirt wall 18 having a conical outer shape is provided below the neck 17, and an annular flange portion 19 is horizontally extended from a lower end of the skirt wall 18.

Further, a hole y through which air can flow in and out is provided below the conduit 10 of the movable part 2. In the case of this embodiment, the split groove is formed.
It is provided continuously with 15, but the reason is the above-mentioned locking part
16 can be easily inserted and may be formed separately. The tubular body 4 is provided with an annular stopper 20 at the upper end, and the tubular wall 4
It is connected to the fixed portion 1 by the convex portion 21 at a specific position. An injection hole e for taking in the contents in the container B is formed in the side portion of the cylindrical body 4, and a small hole z for discharging the contents is provided in the bottom plate 22.

Next, the operation state of each part of the present invention at the time of discharging will be described.
As shown in FIG. 2, when the opening of the container B is directed downward, the contents enter through the injection hole e formed in the side portion of the cylindrical body, and the front lid 9 advances toward the opening, so that the front lid is opened. The contents enter from the inflow port b into the measuring chamber d surrounded by the cylindrical wall 9 and the cylindrical wall 4 and the annular stopper 7. When the front lid 9 advances, the volume inside the container B increases by the volume of the measuring chamber d, so that the inside of the container B is depressurized. The front lid portion 9 enters the container B through the hole y, and the front lid portion 9 continuously moves forward, and when the discharge port a and the measuring chamber d communicate with each other, the rear lid portion that has been moving together with the movable portion 2 until then. 3, the flange 19 abuts the annular stopper 7 while being guided by the skirt wall 18, and the inlet b
Close up. At this time, the measuring chamber d is completely shut off from the inside of the container B, and the contents in the measuring chamber d are discharged through the discharge port a. When the container B is returned to the original vertical state, the air in the container B is discharged to the outside through the small hole x of the front plate 11, and the movable portion 2 quickly returns to the original lowest position, so that the inside of the cylinder body is immediately returned. The contents return below the small hole z in the bottom plate.

<Effect of the device> The metering plug of the present invention has a structure in which the movable part moves inside the cylinder wall while weighing the contents, and since the container can be discharged quantitatively just by tilting the container, the cap may pollute the surrounding area. Moreover, it is extremely practical because it can be used as a content, even from water to highly viscous liquids such as laundry detergent.

In addition, when discharging a fixed amount, the contents enter through the injection hole on the side of the cylinder and flow into the weighing chamber along with the movement of the movable part.Therefore, there is no risk of the movable part being pushed by the rapid movement of the contents when the container is tilted. The weighing accuracy is improved.
