Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a powder that measures and discharges a fixed amount of a powdered material such as a metering plug, particularly powdered detergent and powdered food, by rotating a container. The present invention relates to a metering plug attached to the mouth of a container.

[Conventional technology]

Conventionally, a powder container that discharges a fixed amount of powdered material stored is
As shown in FIG. 4, the metering plug 1 is provided at the mouth B of the container body A.
Is attached, and by rotating the container in one direction so that it is upside down and returning it to the upright state, a certain amount of powdery substance is weighed in the quantitative stopper body 1, and the container is moved again in one direction. It is provided so that only the measured powdery substance is discharged by rotating.

As shown in FIGS. 3 and 4, a fixed amount plug body 1 for measuring a certain amount of this powdery substance is a fixed body 2 equipped with a discharge body portion 21 that is attached to a mouth portion B and is continuous with an opening portion 20 on the upper surface. And the fixed body 2
And a fixed lid 4 attached to cover the mouth B with a weighing body 3 rotatably connected to the fixed body 2 and a through hole 40 corresponding to the opening 20. And the fixed lid 4 which is rotatably attached to the fixed lid 4.
Similarly to the above, the rotary lid 5 having a through hole 50 corresponding to the opening 20.
It consisted of and. The weighing body 3 has a weighing portion 30 corresponding to the lower surface of the discharge barrel portion 21 having an open upper surface, and a connecting portion 33 including an inclined plate 31 and a side plate 32 which are continuous with the upper edge of the weighing portion 30. The base portion of the side plate 32 is pivotally attached to the fixed body 2 so as to be rotatable. Further, the connecting portion 33 forms a measuring auxiliary chamber C with the side surface of the discharge barrel portion 21, and when the container is turned upside down, a powdery material enters the measuring auxiliary chamber C and returns the container to the upright state. At this point, the weighing body 3 rotates by a predetermined amount and the slanted plate in which the powdery material is slanted from the weighing auxiliary chamber C
It passes through the gap between the opening 31 and the discharge barrel 21 and enters the weighing unit 30 for weighing. After that, when the container is turned upside down, the powdery substance measured by the measuring unit 30 is discharged through the opening 20 and the through holes 40 and 50. At this point, the powdered material enters the measuring auxiliary chamber C, and the powdered material enters the weighing section in the same manner as described above by erecting the container, and the powdery material is discharged by a predetermined amount by repeatedly rotating the container. It was set up so that it could be done.

Further, as shown in Japanese Utility Model Publication No. 62-17410, by dividing the measuring unit into a plurality of small chambers, dividing the opening of the fixed body, and selecting the position of the through hole of the rotary lid, a small amount of There was a device to measure and discharge the powdery material as well.

[Problems to be solved by the device]

However, in the quantitative stopper having the above-mentioned structure, when the container is returned to the upright state, momentum is exerted on the powdery substance moving on the inclined sloping plate, and a part of the powdery substance may jump over the measuring section. Therefore, there is an inconvenience that a predetermined amount cannot be measured.

Therefore, it has been a problem to prevent the powdery substance from jumping out and to accurately measure a predetermined amount.

[Means for Solving the Problems]

The present invention has been made in consideration of the above problems, and includes a fixed body having a discharge barrel continuous with an opening on an upper surface, a weighing unit corresponding to a lower surface of the discharge barrel having an open upper surface, and the weighing unit. A measuring body which is connected to the fixed body so as to be rotatable, and a through hole corresponding to the opening of the fixed body. In the fixed amount plug body, which comprises a rotary lid body that covers the opening portion so as to open and close, a protective wall is provided by extending an upper edge facing the connecting portion of the measuring portion upward. A plug is provided to solve the above problems.

[Action]

In the present invention, the protective wall receives the powdery substance moving on the weighing unit, and the powdery substance falls into the weighing unit.

〔Example〕

Next, the present invention will be described in detail based on an embodiment shown in FIGS. 1 and 2. The parts having the same configurations as those of the conventional example are designated by the same reference numerals, and the description thereof will be omitted.

That is, according to the present invention, the upper edge of the weighing body 3 facing the inclined plate 31 is extended upward, and the protective wall 6 facing the inclined plate 31 is provided.
When the container is erected, the protective wall 6 receives the powdery substance moving on the measuring unit 30 from the inclined sloping plate 31 so that the powdery substance falls into the measuring unit 30. (The movement of the powdery substance is indicated by an arrow a). Corresponding to the protective wall 6 extending upward, a recess 7 is provided on the side wall of the discharge barrel portion 21 so as to be continuous when the container is turned upside down.

Further, the side surface 21a of the discharge trunk portion 21 on the side of the auxiliary measurement chamber C is the discharge trunk portion 2
It is inclined to the 1 side, and is designed so that the volume of the measurement auxiliary chamber C is increased.

[Effect of device]

As described above, according to the present invention, a metering plug includes a fixed body having a discharge barrel continuous with an opening on an upper surface, a metering unit having an upper surface opened and corresponding to a lower surface of the discharge barrel, and A weighing body, which is connected to the fixed body so as to be rotatable, and a through hole corresponding to an opening of the fixed body, the weighing body being connected to the fixed body so as to form a measuring auxiliary chamber continuously with the discharge body side surface. In the metering plug body including a rotary lid body that covers the opening portion so as to be openable and closable, a protective wall is provided by extending an upper edge facing the connecting portion of the weighing unit upward, and thus The powdery material that jumps over the weighing unit when it is in the upright state is reliably received by the protective wall that is continuous to the weighing unit, and it is possible to discharge a certain amount of powdery substance at all times without causing variations in weighing. It has excellent practicability.
