Description

[Detailed Description of the Invention] The present invention relates to a plug for quantitatively discharging the contents of powder or granules. The structures of metering stoppers attached to container openings can be roughly divided into those with moving parts and those without. For those with a structure without moving parts, the flow path for the contents inside the metering stopper is always open, and the contents are guided to the outlet after being subdivided once or several times in the preliminary chamber or measuring chamber. . With this structure, each time a portion of the contents is subdivided, a portion of the subdivided contents is moved to another room to maintain quantitative quality.Conversely speaking, the discharge amount decreases each time, and the open flow path Therefore, when the container is tilted during use, the contents that have been subdivided may return to the container, or in some cases, the contents may pass through the metering stopper and be directly discharged. Further, since a preparatory chamber is provided, the metering stopper itself becomes very large compared to the amount of discharged contents, and there are also disadvantages in that the position of the discharge port may be directional. On the other hand, structures with movable parts have drawbacks such as powder or granules getting caught in the movable parts, making them immobile, and the opening/closing structure becoming complicated, requiring a large number of parts and increasing costs. The current situation is that this is not the case.

The present invention was developed in view of the shortcomings of the prior art described above.It is attached to the opening of a container, and by simply tilting the container, a fixed amount can be discharged. This improves discharge efficiency, and although the structure has movable parts, there is no possibility that the contents will get caught and become immovable.Furthermore, when discharging, the movable parts connect the measuring chamber and the discharge port, and the inside of the container is isolated from the inside of the container. The present invention provides a metering stopper with a simple and extremely superior structure, which is highly practical, as the contents are not directly discharged.

The present invention will be explained in detail below based on the embodiments shown in the drawings.

Figure 1 is a cross-sectional view of the metering stopper A of the present invention attached to the opening of a container, and Figure 2 is a plan view thereof.As shown in Figure 1, the metering stopper A of the present invention has a fixed portion. It consists of two parts: 1 and a movable part 2.

The fixing part 1 includes a cylindrical wall 4 forming a discharge port a on an upper cover plate 3 that blocks the opening of the container B except for the discharge port a, and a circumferential wall 5 for attaching the metering stopper A to the opening of the container B. are installed in succession. This circumferential wall 5 may be of a screw-cap type that fits into the thread of the container B from the outside of the opening of another container B of the inner stopper type as shown in FIG. A support plate 6 for suspending the movable part 2 is connected below the cylindrical wall 4, and a hole 7 is provided in the center of the support plate 6. As shown in FIG. 2, the support plate 6 is only a part of the bottom surface of the cylinder wall 4, and most of the remaining part is a window 8 through which the contents reach the outlet a.

The movable part 2 is cup-shaped and has a side wall 9, a bottom wall 10, and an inclined plate 11 connected to each other, and a hanging rod 12 is connected to the center of the bottom wall 10. The tip of this hanging rod 12 is machined to be larger than the hole 7 provided in the support plate 6, and is set at a certain distance from the lower end of the cylindrical wall 4 of the fixed part 1 so that the movable part 2 does not fall into the container B. It has a structure in which it is suspended in the air on the fixed part 1 while maintaining the same. Furthermore, the hole 7 is made larger than the outer diameter of the hanging rod 12, and the movable part 2 can be tilted in all directions from the center line of the metering stopper A using the hole 7 and the tip of the hanging rod 12 as fulcrums. It is possible to move up and down a certain distance. Specific distance is hanging rod 1
2, when the movable part 2 is tilted as shown in FIG. Hanging rod 1 with the maximum length within the range that the continuous part touches
In a state where the movable part 2 having the metering stopper A is suspended at the lowest position when the metering stopper A is positioned vertically, the first
As shown in the figure, this is the distance that extends vertically from the lower end of the cylindrical wall 4 to reach the inclined plate 11. In other words, it is a gap for the contents accumulated on the inclined plate 11 to enter into the measuring chamber b when the container B is in a vertical state.The larger the gap, the easier it is to enter in a short time, and when the container B is in an inclined state. The lower end of the circular wall 4 comes into contact with the inclined plate 11 of the movable part 2, and the contents in the measuring chamber b are guided to the discharge port a without falling into the container B. At this time, as shown in Fig. 3, the lower end of the circular wall 4 and the inclined plate 11 are in contact with each other only in part, and the gap widens upward, but the content is powder or granules. In the case of , the lowest position becomes a bridge, and leakage from nearby gaps is extremely small, and most of the contents in measuring chamber b can be moved to discharge port a.

FIG. 4 is a state diagram of the metering stopper A when the container B is further tilted from FIG. 3 and the contents are discharged from the outlet a. The movable part 2 is pressed toward the fixed part 1 from the entire outside by the weight of the movable part 2 and the contents in the container B, so that the lower end of the circular wall 4 and the inclined plate 11 are in complete contact with each other, and the measuring chamber b and The discharge port a is completely connected, and the contents in the metering chamber b pass through the window 8 and are discharged from the discharge port a. On the other hand, the inside of the container B is blocked off from the outlet a and the measuring chamber b, so that the contents are not directly discharged from the outlet a.

Next, when the discharge is completed and the container B is returned to its original vertical position, the contents that had accumulated between the upper cover plate 3 and the inclined plate 11 in the state shown in FIG.
quickly enters the measuring chamber b to return to the suspended state as shown in Figure 1. Therefore, the amount accumulated between the upper cover plate 3 and the inclined plate 11 is the amount that accumulates in the measuring chamber b.
If the amount is more than the amount that fills the top of the inclined plate 11, the powder or granules in the container B will not directly pass through the window 8, and only the powder or granules in the measuring chamber b can be discharged in a fixed amount.

However, if the remaining amount of the contents in container B decreases, the amount of discharge may decrease. This is because some of the contents accumulated between the upper cover plate 3 and the inclined plate 11 return to the inside of the container B during the process of returning the container B to its original vertical state after the quantitative discharge is completed. be.

To explain in detail, the upper cover plate 3 and the inclined plate 1
1, that is, since the space C is doughnut-shaped, the contents move within the space C when the container B is in the horizontal state during the process of returning it to its original state, as shown in FIG. As shown in the diagram of the contents seen through the upper lid plate 3, the container B is stood vertically with the contents only partially in the space C, and some of the contents enter the measuring chamber B. . Therefore, in order to prevent the above-mentioned phenomenon, it is necessary to suppress the movement of the contents within the space C, and the metering stopper A of the present invention has a dividing plate 13 in the space C and a fixed part 1. It was established in conjunction with As a result, as shown in the view of the contents seen through the upper lid plate 3 in FIG. , the necessary amount is secured and stable emissions are obtained until the end.

As mentioned above, the metering stopper of the present invention can be used continuously many times by simply tilting the container to discharge a metered amount and returning the container to its original vertical position, and has no directionality in discharge. Although it has a structure with a movable part, the number of parts is small with only two parts, and by suspending the movable part from the fixed part with a hanging rod, there is no possibility that the movable part will become stuck due to clogging with contents. Since the cup-shaped measuring chamber has an inclined plate connected to the opening side, it is easy for the contents to enter the measuring chamber, and when the container is tilted, a part of the inclined plate makes contact with the cylindrical wall that forms the discharge port. The movable part acts as a bridge to the discharge port and guides most of the contents in the measuring chamber to the discharge port, resulting in extremely high discharge efficiency.Also, due to the vertical movement of the movable part, the entire circumference of the lower end of the cylinder wall is tilted during discharge. Because it comes into contact with the plate and isolates the inside of the container from the discharge port and measuring chamber, the contents inside the container are not directly discharged, and by providing a dividing plate, the contents can be discharged in a stable and quantitative manner until the end. This is a highly practical quantitative stopper with extremely excellent functions such as
