Description

The present invention is an impact device that is mounted on a powder container that stores powder and can give an impact to the container in order to crush the powder solidified in the container, and an impact device including the impact device and the powder container. It is related to a powder container with a sticker.

Generally, a powder container is used in which the contents of the powder are stored and the contents can be discharged from the opening by swinging out in a tilted posture. In such a powder container, for example, when a hygroscopic content is stored, the content may absorb moisture in the air after opening and a part of the content may be solidified. When such a mass becomes large, it cannot be discharged from the opening, and it also blocks the opening at the time of swinging and hinders the discharge of the unsolidified contents.

For such a problem, for example, Patent Document 1 discloses a container having a fine mesh in the opening. According to this container, the fine strips that make up the net have a small unit area, so when the lumps collide with the net due to the swinging operation, a large force is applied to the lumps by the fine strips of the net, and the lumps are crushed.

Japanese Unexamined Patent Publication No. 10-167302

However, in the container of Patent Document 1, since the mesh is fine, in order to discharge the solidified contents, it must be crushed more finely than the mesh. For this reason, it is assumed that the solidified contents cannot be discharged unless the drawing operation is continued for a long time, which requires labor.

An object of the present invention is to solve such a problem, and to provide an impact device capable of crushing solidified powder with less effort, and a powder container with an impact device provided with the impact device. The purpose is to do.

The present invention has a base mounted on a powder container for accommodating powder and a pressing portion that can be pushed into the base, and an impact mechanism that gives an impact to the powder container by pushing into the pressing portion. It is an impact device equipped with
The impact mechanism is
The first member that extends along the axis and has protrusions on the outer peripheral surface,
A second member having an axial groove through which the protrusion is inserted and a circumferential groove connected to the axial groove while holding the first member slidably in the axial direction.
A third member having an inclined groove through which the protrusion is inserted while holding the second member so as to be slidable in the axial direction.
The first member is urged in the axial direction toward the pressing portion in a state where the pressing portion is provided on the second member and the third member is attached to the base, or the second member is A first elastic body that is attached to the base and that urges the first member in the axial direction toward the base in a state where the pressing portion is provided on the third member.
The second member is provided with the pressing portion and the second member is urged in the axial direction toward the pressing portion in a state where the third member is attached to the base, or the second member A second elastic body that is attached to the base and that urges the second member in the axial direction toward the base in a state where the pressing portion is provided on the third member is provided.
The inclined groove pushes the protrusion into the pressing portion against the protrusion that fits in the circumferential groove in the state before being pushed into the pressing portion, and moves the protrusion to the axial groove. It is an impact device having a first inclined edge.

The inclined groove comes into contact with the protrusion when the first elastic body and the second elastic body return after being pushed into the pressing portion, and the protrusion is moved from the axial groove to the circumferential groove. It is preferable to have a bi-sloping edge.

The base preferably has an annular wall mounted on the bottom of the powder container.

The present invention is also a powder container with an impact device including the powder container and any of the impact devices.

According to the impact device of the present invention, when the pressing portion is pushed in, the protrusion of the first member that was contained in the circumferential groove in the state before pushing is moved to the axial groove by the first inclined edge portion of the inclined groove. That is, the first member whose movement in the axial direction is restricted when the protrusion is contained in the circumferential groove is released from the restriction when the protrusion moves to the axial groove, so that the first elastic body is attached. It moves vigorously with power. As a result, the protrusions collide with the mating object (for example, the edge at the end of the axial groove or the edge of the inclined groove) to generate an impact, which is transmitted to the powder container equipped with the impact device. The mass can be crushed. Further, since the powder container can be impacted only by pushing the pressing portion, the labor for crushing the solidified powder can be reduced.

The first elastic body 17 incorporated in this way urges the first member 13 toward the base 11'when the pressing member 16'is pushed in. Similarly, the second elastic body 18 urges the second member 14 toward the base 11'.

Even in the impact device 10'in which the base 11'and the pressing member 16' are incorporated in this way, the protrusion 13d housed in the circumferential groove 14f as shown in FIG. 7A is shown in FIG. 7B. By pushing the pressing member 16'in this way, it is pressed by the first inclined edge portion 15g and moves in the circumferential groove 14f toward the axial groove 14e. Then, as shown in FIG. 7C, when the protrusion 13d reaches the axial groove 14e, the first member 13 vigorously moves toward the base 11'by the urging force of the first elastic body 17. Then, the protrusion 13d hits the second inclined edge portion 15h to generate an impact, which is transmitted to the powder container 1, so that the mass of the contents in the powder container 1 can be crushed.

After that, when the pressing member 16'is released, the pressing member 16'moves toward the original position together with the second member 14 by the urging force of the second elastic body 18. Then, as shown in FIG. 7D, when the circumferential groove 14f approaches the protrusion 13d housed in the axial groove 14e, the protrusion 13d is formed along the second inclined edge portion 15h that abuts on the protrusion 13d. It moves toward the circumferential groove 14f. After that, since the state of FIG. 7A is restored, the impact can be efficiently applied to the powder container 1 by repeating pushing into the pressing member 16'and releasing the pressing member 16'in this embodiment as well.
