Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container having a metering mechanism for dispensing powders, granules, etc.

When taking out a fixed amount of powder, granular materials, synthetic detergent, etc. from a container, a measuring container such as a cup is used, or it is often shaken out directly from the container, which may contaminate the surrounding area or cause variations in the amount used. This is uneconomical.

Various containers with built-in metering mechanisms have been invented, but very few have been put into practical use. -This is the exit,
There are practical problems, such as the fact that the container is stuck to the bottom of the box, the container simply rotates, or there is a special shaking method other than the return method. This is because the amount of vibration changes significantly, resulting in poor quantitative accuracy. An object of the present invention is to provide a container equipped with a simple quantitative dispensing mechanism that can always dispense a fixed amount of powder or granules regardless of the amount remaining in the container or the inclination angle of the container at the time of dispensing. For this purpose, a powder outlet is provided at the upper part of the side wall or a corner of the upper wall of the sealed box, and a slant plate is extended diagonally upward from the inner surface of the side wall below the powder outlet. A required interval is provided between the upper walls, and a stopper is provided in the extending direction of the mirror slanted plate and near the upper end of the slanted plate, which does not hinder the inflow and outflow of powder particles, and together with the side wall and the slanted plate, the powder flow Extend the partition plate from the inner surface of the side wall or top wall toward the center of the box body so as to surround the outlet and form an outflow chamber until the top green of the slant plate is located almost perpendicularly below the bottom edge of the partition plate. A rotating shaft is provided at the upper end of the plate, and the rotating plate is extended upward from the rotating shaft to form an inlet between the upper end of the rotating slope and the upper wall, and the middle part of the rotating plate is connected to the lower part of the slope. The rotating plate is extended so that a measuring chamber is formed by the rotating plate above the middle part of the rotating plate, the upper surface of the partition, both side walls, and the corners of the upper wall when it comes into contact with the end. The present invention provides a container having a mechanism for dispensing a fixed amount of powder, etc., in which the middle part of the upper surface of the moving plate serves as the lower end of the partition plate, and the lower surface of the rotating plate serves as the stopper alternately.

A preferred embodiment of the present invention will be described below. FIG. 1 shows a metering dispensing mechanism 10. As shown in FIG.

A front plate 14 and a rear plate 16 are arranged below the front and rear sides of a horizontal husband plate 12 having a rectangular plate shape, and an inclined plate 18 is provided to close the narrow lower ends of the front plate 14 and rear plate 16. . A rotating plate 22 is provided with the upper end green of the inclined plate 18 serving as a lower rotating shaft 20, and a pestle-shaped stopper 24 is constructed on the front plate 14 and rear plate 16 near the upper end of the rotating plate 22. The lower end of the partition plate 28 extending in the direction of the rotating plate 22 from the lower end of the side plate 26 slightly hanging down from the left end green of the top plate 12 and the inclined plate 18 form a closed part with a slight interval between them. Vertically below the lower edge of the partition plate 28 is the frame slant plate 18.
This is the lower rotation shaft 20 which is the upper end. The opening between the upper end of the spreading plate 22 and the husband plate 12 is an inlet 30, and the area between the lower end of the inclined plate 18 and the lower end of the side plate 26 is an outlet. The upper part of the partition plate 28 forms a quantitative chamber 32, and the lower part forms an outflow chamber 34. The above-mentioned quantitative dispensing mechanism is attached to the inside of the upper corner of the box as shown in Fig. 2, but each plate member is extended from the inner wall of the box.
A wall portion can be formed. Next, the operation of the present invention will be described.

Before use, a powder outlet 38 is opened along the perforations provided in the side wall 36 of the box body, which is connected to the outlet of the cutting/opening mechanism 10. In FIG. 6, the detergent 40 filled inside the box in an upright state is attached to the lower rotating shaft 20 of the rotating plate 22.
The amount is deposited further downward, and the metering chamber 32 and outflow chamber 34 of the metering dispensing mechanism 10 are empty. In FIG. T, when the box body is moved to the left so that the powder outlet 38 of the box body faces downward, the detergent 40 inside the box body is transferred to the rotating plate 22 according to the movement.
The center of the upper surface of the rotating plate 22 begins to press the partition plate 28 to the left.
It hits the lower end and completely blocks the metering chamber 32 and the outflow chamber 34. In FIG. 8, the box is tilted to the left by about 1200 degrees from the original position, and the detergent flows into the metering chamber 32 and fills it.

Since the tip of the rotating plate 22 extends further than the tip of the partition plate 28, this extension creates a space where some detergent does not enter according to the angle of repose of the powder, but there is some space. Even in this case, as shown in Figure 9, this space is completely filled with powders and granules of detergent etc. when the paper box returns to its value, so there is no problem with the accuracy of the re-drawing, and there is no problem in the next step. Since the detergent in the metering chamber has the effect of pressing the upper part of the rotary plate and promoting its return action, the extending portion of the rotary plate 22 actually improves the metering action. In FIG. 9, when the box is returned to its original state, the detergent remains in the metering chamber 32, and excess detergent returns to the box.

By making the upper part of the rotating plate 22 heavy, the rotating operation becomes sensitive and reliable, and the closed state is stabilized by the weight.
For this reason, the spreading plate remains closed until the box returns to a nearly vertical position, and the process from closing to opening is instantaneous, resulting in high repeatability and quantitative accuracy. In FIG. 10, the box returns to its original state, and the rotary plate separates from the tip of the partition due to its own weight and the weight of the detergent, rotates to the right, and hits the stopper 24.

The detergent is guided to the inclined surface of the partition plate and flows into the metering chamber 32 and the outflow chamber 34.
It flows into the outflow chamber through the entrance between the two. FIG. 11 shows the case where the box body is moved again, the rotating plate hits the partition plate, the detergent is refilled into the empty metering chamber, and the detergent in the outflow chamber is removed from the powder outlet 38. flows downward from the

The inclination angle and opening of the inclined plate of the quantitative dispensing mechanism in this invention
The size of the part, the direction in which the partition plate extends, etc. are designed according to the required single-use amount depending on the nature of the contents, but the amount can be easily adjusted by slightly adjusting the direction in which the partition plate extends. be able to. In this way, in the present invention, quantitative determination can be carried out regardless of the size of the container or the particle size of powders or granules. Since the spacer and the outflow chamber are completely partitioned, quantitative accuracy is high, and since the rotation axis is provided almost vertically below the lower end of the partition plate, the rotation and return of the rotation plate is sensitive.

It can be used in the same way as the conventional shaker method of tilting back from 90o to 120o from the vertical direction when the container is set upright. By attaching the two with adhesive tape or integrally forming the two through plastic grooves, it is possible to mass-produce them at low cost, which is of great practical benefit. Although the present invention has been variously explained above with reference to preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. It is.
