Next, the discharge operation of the quantitative stopper for powdery particles of the present invention and the principle of measurement by the operation will be described in detail with reference to FIGS. The container is a rectangular column-shaped paper container in which the metering plug is attached to the mouth part of an inclined plate inclined 45 degrees on the top with the inflow port facing upward and filled with powder or granular contents. First, as shown in FIG. 2 (a), when the container (20) is tilted upside down, the contents in the container move toward the top of the container, and the contents (30) of the metering stopper (10) It flows into the first measurement chamber (11) in the metering plug from the inlet (111) above the peripheral wall (110) of the main body (100) (the arrow in the figure indicates the movement of the contents of the metering plug). ). The amount of the inflow is regulated by the vertical height of the inlet and the position of the partition plate (220), whereby the first measurement is performed. In addition, the ease of inflow depends on the projected area of the inlet. This metering plug is cut diagonally inward from both ends of the horizontal notch line from the inlet of the conventional metering plug, so the projected area is large, the contents can easily flow in, and the remaining The amount is also small. Next, as shown in FIG. 2 (b), when the container is returned to the upright state, the contents of the primary measurement chamber that has been weighed may partially return to the container from the inlet. Falls into the second weighing chamber (12) located below. When it is inclined at 45 degrees as in the case of the fixed amount plug, the amount of the protrusion protrudes and accumulates below the discharge hole (13). The metering plug is designed so that the inclined plate (221) connected to the tip of the partition plate comes into contact with the surface of the contents (30) that have fallen into the second measuring chamber. Next, as shown in FIG. 2 (c), when the container is again inverted, the contents in the container are transferred from the inlet of the peripheral wall to the first metering in the metering plug as in FIG. 2 (a). The flow into the chamber (11), and a part of the contents in the second weighing chamber (12) is first surplus by the weighing action of the inclined plate (221) connected to the tip of the partition plate of the weighing switching unit. Returning to the measurement chamber, the measurement is performed in the first measurement chamber. At the same time, the other contents in the second measuring chamber secondarily measured by the measuring action of the inclined plate pass through the discharge hole (13) and are discharged out of the container through the discharge port (14). The amount of the content to be discharged is always discharged from the discharge port within an error range that does not cause a problem in use by the first measurement and the second measurement. The subsequent discharging operation repeats the state shown in FIG. 2B and the state shown in FIG. FIG. 3 is an explanatory diagram showing the discharging operation when the metering plug is rotated 180 degrees with the switching lever and the amount to be metered is switched to another amount and the principle of metering by that operation. This is performed in the same manner as in FIG.
[0009]
Next, the method of changing the metering plug for powdery particles according to the present invention in two stages will be described with reference to FIGS. 1A and 1B. In the state shown in FIG. When the rotating ring (210) is rotated counterclockwise by (211) and the weighing switching unit (200) is rotated 180 degrees, the distance from the surfaces on both sides of the partition plate (220) to the inner surface of the peripheral wall (110) is different. 1 (b), the distance from the partition plate surface of the first measurement chamber (11) to the inner surface of the peripheral wall changes, and an inclined plate connected to the tip of the partition plate ( The direction of 221) is on the opposite side. As a result, the measurement in the first measurement chamber and the measurement of the contents in the second measurement chamber (12) change between the state in FIG. 1 (a) and the state in FIG.
