It is attached to the main body portion 3a so as to face the side wall 3a1 with sandwiching therebetween. The cover 3b is provided with a rod-shaped protrusion 3b1, and the rod-shaped protrusion 3b1 is fitted inside the cylindrical protrusion 3a5 protruding from the inner surface of the side wall 3a1, whereby the cover 3b is fixed to the main body 3a.

One side portion (right side portion in FIG. 1) of the container body 3 is open, and the opening is closed by the operation portion 4 a of the opening/closing operation member 4. More specifically, the operation portion 4a has a side wall 4a1 and a pair of side walls 4a2, and has a U-shaped cross section in which the depth gradually increases from the bottom wall 3a3 side toward the top wall 3a2 side. It has and is fitted in the opening at one side of the container body 3. As a result, a part of the side wall of the container body 3 is configured by the operation portion 4a of the opening/closing operation member 4, and the opening is closed.

The opening/closing operation member 4 is swingably supported by the bottom wall 3a3 via a hinge 6 at the lower end portion of the side wall 4a1. As a result, by operating the operating portion 4a in the pushing direction (counterclockwise direction in FIG. 1) about the hinge 6, the opening/closing operation member 4 is moved from the closed position shown in FIG. It can be moved in a swiveling manner toward the inside of the container body 3.

In the present embodiment, the main body portion 3a of the container main body 3, the opening/closing operation member 4, and the hinge 6 are integrally formed of a resin material. FIG. 4 shows the shape of a molded product 7 in which the main body 3a, the opening/closing operation member 4 and the hinge 6 are integrally molded by injection molding of a resin material using a mold (not shown) for injection molding. The cover 3b is attached to the main body 3a of the molded product 7 molded into the shape shown in FIG. 4 to form the container main body 3, and the opening/closing operation member 4 is rotated around the hinge 6 so that the portion of the side wall 4a2 is removed. By pushing the inside of the container, the opening of the container body 3 can be closed by the operation portion 4a. In this way, the body portion 3a of the container body 3, the opening/closing operation member 4, and the hinge 6 are integrally formed of a resin material to facilitate the manufacture of the granular material storage container 1 and reduce the manufacturing cost. It can be reduced.

As shown in FIGS. 1 and 3, the top wall 3a2 of the container body 3 is provided with a discharge port 8 for discharging the particulate matter 2 stored in the storage chamber 5 to the outside of the container body 3. Has been. The ceiling wall 3a2 is formed in a curved shape in which the height from the bottom wall 3a3 gradually decreases from the opening side closed by the operating portion 4a toward the side wall 3a4 side, and the discharge port 8 is provided with the granular material 2 It is formed in such a size that it can pass through, and is provided in a substantially central portion of the ceiling wall 3a2 in the left-right direction in FIG.

Inside the container body 3, a measuring passage 10 that connects the storage chamber 5 to the discharge port 8 is provided. The metering passage 10 is partitioned and formed by a pair of partition walls 10a, and the lower end side thereof in FIG. 1 is an inlet 10b opening to the storage chamber 5. The granular material 2 stored in the storage chamber 5 can enter the inside of the measuring passage 10 through the introduction port 10b. The internal volume of the measuring passage 10 is large enough to accommodate only one granular material 2. That is, the metering passage 10 has a size such that only one granular material 2 can be stored in the portion between the inlet 10b and the outlet 8. Therefore, a predetermined amount, that is, one granular material 2 can be measured by the measuring passage 10.

The opening/closing operation member 4 is integrally provided with a first wall 4b extending from the operation portion 4a along the inner surface of the top wall 3a2 of the container body 3. A first opening/closing portion 4b1 formed in a rectangular plate shape is integrally provided on the tip side of the first wall 4b, and when the opening/closing operation member 4 is in the closed position shown in FIGS. The outlet 8 is closed by the opening/closing part 4b1. Further, a first cutout portion 4b2 is provided adjacent to the first opening/closing portion 4b1 in a portion of the first wall 4b between the first opening/closing portion 4b1 and the operation portion 4a. The first cutout portion 4b2 is formed by notching the first wall 4b in a rectangular shape from the side wall 3a1 side toward the cover 3b side, and the opening/closing operation member 4 serves as a fixed amount discharge position and a large amount discharge position. When it faces the discharge port 8, the discharge port 8 is opened so that the granular material 2 can pass from the measuring passage 10 toward the discharge port 8.

Further, the opening/closing operation member 4 is integrally provided with a second wall 4c extending from the operation portion 4a toward the introduction port 10b. The second wall 4c is provided closer to the bottom wall 3a3 than the first wall 4b. A second opening/closing portion 4c1 formed in a rib shape having a width narrower than that of the introduction port 10b is integrally provided on the tip side of the second wall 4c. When the opening/closing operation member 4 is in the closed position shown in FIGS. 1 and 3, the second opening/closing portion 4c1 is displaced from the introduction port 10b, and the introduction port 10b is open toward the storage chamber 5. Further, a second cutout portion 4c2 is provided adjacent to the second opening/closing portion 4c1 in a portion of the second wall 4c between the second opening/closing portion 4c1 and the operation portion 4a. The second cutout portion 4c2 is formed by cutting out the second wall 4c in a rectangular shape from the side wall 3a1 side toward the cover 3b side, and the opening/closing operation member 4 becomes a large discharge position and the inlet 10b. It is formed in a size that allows the particulate matter 2 to enter from the storage chamber 5 toward the measuring passage 10 when facing the container.

Therefore, when the opening/closing operation member 4 is in the closed position, the introduction port 10b is opened but the discharge port 8 is closed, and the granular material 2 is stored in the granular material storage container 1 without being discharged from the discharge port 8. To be in a state. From this state, when the operation portion 4a is operated in the pushing direction to move the opening/closing operation member 4 toward the inside of the container body 3 from the closed position to the fixed amount discharge position, the introduction port 10b is closed by the second opening/closing portion 4c1. At the same time, the discharge port 8 is opened by the first cutout portion 4b2. Then, when the operation portion 4a is further operated to move the opening/closing operation member 4 from the fixed amount discharge position to the large amount discharge position, the discharge port 8 is opened by the first cutout portion 4b2 and the second cutout portion 4c2 is opened. The inlet 10b is opened.

In the present invention, to “close” or “close” the discharge port 8 or the introduction port 10b does not only completely seal the entire opening portion of the discharge port 8 or the introduction port 10b, but also the discharge port 8 It also includes blocking part of the inlet 10b so that the granular material 2 cannot pass through. For example, in the present embodiment, the rib-shaped second opening/closing portion 4c1 having a width narrower than that of the introduction port 10b is arranged at the introduction port 10b so that the introduction port 10b is blocked to the extent that the granular material 2 cannot pass through. However, the shape of the second opening/closing portion 4c1 can be variously changed as long as the shape can block the introduction port 10b to the extent that the granular material 2 cannot pass through.

Further, "opening" or "opening" the outlet 8 or the inlet 10b means not only completely opening the entire opening of the outlet 8 or the inlet 10b, but also the outlet 8 or the inlet 10b. It is also included to open a part of the so that the granular material 2 can pass through.

On the inner surface of the top wall 3a2, a locking piece 11 is integrally provided adjacent to the discharge port 8 on the operation portion 4a side. The locking piece 11 projects from the inner surface of the top wall 3a2 and locks the edge portion of the first opening/closing portion 4b1 when the opening/closing operation member 4 is in the closed position. This prevents the opening/closing member 4 from moving toward the outside of the container body 3 beyond the closed position, and prevents the opening/closing member 4 from being detached from the container body 3.

The locking piece 11 is formed in a wedge shape that is gradually inclined from the operation portion 4a side toward the discharge port 8 side so that the protruding height from the inner surface of the ceiling wall 3a2 is gradually increased. Accordingly, when the opening/closing operation member 4 is pushed toward the inside of the container body 3 from the state of the molded product 7, the tip of the first opening/closing portion 4b1 can easily get over the locking piece 11.

A leaf spring portion 12 is integrally provided at the lower end of the operation portion 4a adjacent to the hinge 6. The leaf spring portion 12 is formed in a plate shape extending along the bottom wall 3a3, and when the opening/closing operation member 4 is in the closed position, the leaf spring portion 12 is elastically deformed in a slightly bent state, and the opening/closing operation member 4 is caused by the elastic force. Is urged toward the closed position. Therefore, even if the operation portion 4a is operated to move the opening/closing operation member 4 to the fixed amount discharge position or the large amount discharge position, the opening/closing operation member 4 is closed by the elastic force of the leaf spring portion 12 by releasing the operation force. It can be automatically returned to the position. As a result, it is possible to prevent the particulate matter 2 from being unexpectedly discharged from the particulate matter storage container 1 by keeping the discharge port 8 open.

On the inner surface of the ceiling wall 3a2, a climbing projection 13 is integrally provided so as to project from the inner surface. When the opening/closing operation member 4 is moved from the closed position to the fixed amount discharge position by the operation of the operation portion 4a, the tip of the first opening/closing portion 4b1 comes into contact with the overriding protrusion 13. Thus, the user who operates the operation unit 4a can recognize that the opening/closing operation member 4 has reached the fixed amount discharge position. The boarding protrusion 13 has a height such that the first opening/closing part 4b1 can move over the boarding protrusion 13 by operating the operation portion 4a. Therefore, by further operating the operation portion 4a, the opening/closing operation member 4 can be moved from the fixed amount discharge position to the large amount discharge position. In the present embodiment, the first opening/closing part 4b1 is formed in a wedge shape whose thickness decreases toward the tip thereof, so that the first opening/closing part 4b1 itself is flexibly deformed to more easily. It is possible to get over the overhanging protrusion 13.

Blocking walls 14 and 15 for blocking the movement of the granular material 2 to the lateral region of the metering passage 10 are integrally provided on the partition wall 10a that defines the metering passage 10. In addition, a guide wall 16 is integrally provided on the main body 3a below the blocking wall 14 on the left side in FIG. The guide wall 16 allows the granular material 2 in the storage chamber 5 to be efficiently guided toward the introduction port 10b when the container body 3 is tilted. The second opening/closing portion 4c1 is configured to move between the blocking wall 14 and the guide wall 16 when the opening/closing operation member 4 is between the fixed amount discharging position and the large amount discharging position.

When the opening/closing operation member 4 moves from the closed position to the fixed amount discharge position, the side wall 4a1 of the operation portion 4a is in a state of being along the edges of the side wall 3a1 and the cover 3b. Therefore, in order to facilitate the operation of the operation portion 4a when moving the opening/closing operation member 4 from the fixed amount discharge position to the large amount discharge position, the side wall 3a1 and the cover 3b are provided with the operation concave portion 17 at the edges thereof. Has been.

Further, stopper recesses 18 are provided at the edges of the pair of side walls 4a2 of the operating portion 4a. The stopper recess 18 is formed to have a size such that the cylindrical projection 3a5 can be inserted therein. When the opening/closing operation member 4 is in the large discharge position, the stopper recess 18 comes into contact with the cylindrical projection 3a5 to open the opening/closing operation member 4 in the large discharge position. Regulate movement beyond.

Next, a method of using the granular material container 1 having such a configuration will be described with reference to FIGS.

In the normal state, as shown in FIG. 5, the opening/closing operation member 4 is held in the closed position by the elastic force of the plate spring portion 12, and the discharge port 8 of the granular material storage container 1 is closed by the first opening/closing portion 4b1. It becomes a state. Further, in this state, the second opening/closing part 4c1 is displaced from the inlet 10b and the inlet 10b of the measuring passage 10 is opened to the storage chamber 5, so that the container body 3 has the outlet 8 downward. The granular material 2 stored in the storage chamber 5 can be caused to enter the measuring passage 10 by inclining so that

When the granular material 2 is taken out from the granular material storage container 1 by a predetermined amount (one by one), the container body 3 is tilted so that the discharge port 8 is on the lower side as described above, and the like. In a state where the granular material 2 stored in the container 5 has entered the measuring passage 10, as shown in FIG. 6, the operation portion 4a is operated to move the opening/closing operation member 4 from the closed position to the fixed amount discharge position. Let When the opening/closing operation member 4 reaches the fixed amount discharge position, the first opening/closing part 4b1 is displaced from the discharge port 8 and the discharge port 8 is opened by the first cutout part 4b2. Therefore, by tilting the container main body 3 such that the discharge port 8 is located downward, it is possible to discharge one particle of the granular material 2 weighed in the measuring passage 10 from the discharge port 8 to the outside. At this time, since the introduction port 10b of the measuring passage 10 is closed by the second opening/closing portion 4c1, it is possible to discharge the granular material 2 other than one granular material 2 measured in the measuring passage 10 to the outside. It can be held in the storage chamber 5. In this way, by operating the operation portion 4a to move the opening/closing operation member 4 from the closed position to the fixed amount discharge position, the granular material 2 can be taken out from the granular material storage container 1 by a predetermined amount.

After the granular material 2 is taken out, the opening/closing operation member 4 can be automatically returned to the closed position by the spring force of the plate spring portion 12 by canceling the operation of the operation portion 4a. Then, by performing the above operation again, it is possible to take out further another granular material 2 by a predetermined amount.

On the other hand, when a large amount of the granular material 2 is taken out from the granular material storage container 1 at one time, as shown in FIG. 7, the operation portion 4a is operated to move the opening/closing operation member 4 to the large amount discharge position. At this time, the measuring passage 10 may be in a state where the particulate matter 2 has entered or a state where the particulate matter 2 has not entered. When the opening/closing operation member 4 reaches the large discharge position, the first opening/closing part 4b1 is displaced from the discharge port 8 and the discharge port 8 is opened by the first cutout part 4b2, and the second opening/closing part 4c1 of the weighing passage 10 is opened. The inlet 10b, which is displaced from the inlet 10b, is also opened by the second cutout portion 4c2. Therefore, since the discharge port 8 is in communication with the storage chamber 5 through the measuring passage 10, the container body 3 is stored in the storage chamber 5 by inclining the container body 3 so that the discharge port 8 faces downward. A large number of the granular materials 2 present can be continuously discharged from the discharge port 8 to the outside through the measuring passage 10. In this way, by operating the operation portion 4a to set the opening/closing operation member 4 to the large amount discharge position, a large amount of the granular material 2 can be taken out from the granular material storage container 1 at one time. To discharge the granular material 2, the operation of the operation portion 4a is released and the opening/closing operation member 4 is returned to the fixed amount discharge position or the closed position by the spring force of the leaf spring portion 12, or the container body 3 is moved upward by the discharge port 8. It can be stopped by returning to the facing posture.

As described above, according to the granular material storage container 1, a simple operation of only selectively moving the opening/closing operation member 4 from the closed position to the fixed amount discharge position or the large amount discharge position by operating the operation portion 4a. Thus, it is possible to easily switch between a fixed amount discharge in which a predetermined amount of the granular material 2 is taken out and a large amount discharge (free amount discharge) in which a large amount of the granular material 2 is taken out at once.

It is needless to say that the present invention is not limited to the above-mentioned embodiment and can be variously modified without departing from the scope of the invention.

For example, in the above-described embodiment, the granular material storage container 1 is configured to be able to take out the granular material 2 one by one by setting the opening/closing operation member 4 to the fixed amount discharging position, but the present invention is not limited to this. For example, by setting the metering passage 10 to have a size for accommodating a plurality of particles 2, the opening/closing operation member 4 may be set to a fixed amount discharge position so that a plurality of particles 2 can be taken out.

Further, in the present embodiment, the opening/closing operation member 4 is configured to swing around the hinge 6, but the present invention is not limited to this, and the container body 3 extends from the closed position to the large amount discharge position via the fixed amount discharge position. It may be configured to move linearly with respect to.

Further, although the container body 3 and the opening/closing operation member 4 are integrally formed with the hinge 6 in the above-described embodiment, the present invention is not limited to this, and the container body 3 and the opening/closing operation member 4 are separated. It is also possible to form them and connect them by a hinge 6.
