BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metering plug with a variable metering function for quantitatively discharging powdered or granular foods, detergents, medicines and other contents.

[0002]

2. Description of the Related Art As a conventional technique of a metering plug, for example,
The one disclosed in Japanese Utility Model Publication No. 4-1093 is known. That is, as shown in FIG. 5, a cup-shaped main body (100) having a circumferential wall (110) and a bottom wall (120) and having an inflow port (111) on a side surface, and a canopy (51).
0), a vertical plate (520) and an inclined plate (530), and a partitioning part (500), which is attached to the opening of the container (20), and is a fixed-quantity plug for powder and granular material (10), A preliminary chamber (14) surrounded by the circumferential wall above the upper ends of the vertical plate, the canopy and the inclined plate by fitting the main body and the partition into each other, and the preliminary chamber. A replenishment chamber (15) which is located below the replenishment chamber and which is communicated with the inside of the container main body through an inflow port and is surrounded by the inclined plate and a cup-shaped main body having the same height as the inclined plate; Located adjacent to the measuring chamber (11) surrounded by the circumferential wall below the inclined plate and the preparatory chamber and the replenishing chamber via a partition, and surrounded by a part of the circumferential wall and the vertical plate. Partitioned with the outlet (17),
A recess (113) is provided on the outlet side of the measuring chamber, the inlet has a lateral width corresponding to approximately half the circumference of the main body, and the sloping plate of the partitioning portion is parallel to the horizontal plane of the plug body. It is a metering plug for powdery or granular material, characterized in that it is inclined at the angle of repose of the object.

[0003]

The conventional metering plug as disclosed in Japanese Utility Model Publication No. 4-1093 described above can always discharge only a fixed amount at the time of use. For this reason, at the time of use, the user is strongly required to provide a metering variable function to the metering plug so that the discharge amount can be adjusted to the purpose of use, for example,
Japanese Utility Model Laid-Open No. 2-148962 was devised. According to this invention, an inflow port is formed on a side surface of a cup-shaped main body attached to an opening of a container over a substantially half circumference, and a discharge port is provided on a side opposite to the inflow port of a fixed lid that seals an upper opening of the main body. And the rotating lid portion is in sliding contact with the fixed lid portion such that the opening area of the discharge port is adjustable. However, since this variable metering plug regulates the discharge amount by adjusting the opening area of the discharge port and does not change the metering itself, uneven discharge amount may occur during repetition. .

The present invention meets the above-mentioned strong demand of the user, and provides a metering stopper with a metering variable function capable of metering the quantity by varying the quantity to be discharged during use. It is a thing.

Moves toward the opening of the container, and the contents (1
11) flows into the measuring chamber (11) in the metering plug (the arrow in the figure indicates the movement of the contents in the metering plug). The amount of the inflowing contents is regulated by the position of the inflow port and the capacity of the measuring chamber to perform the primary measurement.
Next, as shown in (b), when the container is returned to the upright state,
Some of the weighed contents in the weighing chamber return to the container through the inlet, but most of the contents fall and accumulate in the waiting chamber (12) located below. Next, as shown in (c), when the container is inverted and inclined again, the contents in the container flow into the measuring chamber in the metering stopper body from the inlet of the peripheral wall, as in the case of (a). In addition, a part of the contents in the standby chamber is returned to the weighing chamber and is also weighed in the weighing chamber. At the same time, other contents in the standby chamber are
0) and is discharged to the outside of the container through the discharge port (240). The amount of the discharged contents is regulated by the interval (13) between the lower end of the discharge hole and the bottom wall of the main body to carry out the secondary measurement, and the contents are always usable in no problem. A fixed amount is discharged from the discharge port (240) within an error range.
Next, as shown in (d), when the container is returned to the upright state,
Some of the weighed contents in the weighing chamber return to the container through the inlet, but most of the contents fall and accumulate in the waiting chamber (12) located below. In the subsequent discharging operation, the state shown in (c) and the state shown in (d) are repeated.

Further, the method of varying the measurement of the metering cap with the metering variable function of the present invention is the same as the body part (10) of the metering stopper.
When the main body part is rotated counterclockwise with respect to the lid part (200) by the sliding knob (131) provided on the flange (130) of FIG. 0), as shown in FIGS. 1B and 1C, the lid part is The angle between the back plate (232) and the hanging plate (112) of the main body is reduced by the amount of rotation, and the capacity of the measuring chamber (11) is reduced. At the same time, the injection port (111) provided on the peripheral wall (110) of the main body also has the discharge hole (2
It is closed by the peripheral wall (231) of 30). As a result, the first
Subsequent weighing will be less variable, reducing the quantity discharged. When the sliding knob is rotated to the right, the primary measurement increases and the discharge amount increases.
