Description

The present invention relates to a granular material storage container.

There is known a granular material storage container that can store and carry granular materials such as tablets and sprinkle the granular materials from an outlet. As described in Patent Document 1, for example, this type of granular material storage container has a container body having a rectangular shape in a plan view and having a storage portion for accommodating granules inside, and a container having a hollow inside. It has a case body in which the main body can be inserted and removed.

In the container body, the peripheral wall protrudes from the peripheral edge of the rectangular bottom plate in a plan view, and the accommodating portion is formed inside the peripheral wall. The accommodating portion opens on the side opposite to the bottom plate side. The container body has an outlet protruding from the peripheral wall on the short side to one side in the longitudinal direction. The outlet communicates with the accommodating portion and opens on the side opposite to the bottom plate side. A guide plate that protrudes into the accommodating portion and extends in the longitudinal direction is formed inside the peripheral wall that extends in the longitudinal direction on the other side of the container body in the longitudinal direction from the outlet.

An inclined surface inclined toward the outlet side is formed on one side of the guide plate in the longitudinal direction. A passage through which granules can pass is formed between the inclined surface and the outlet.

When taking out the granules in the accommodating portion from the outlet, the container body is slid to one side in the longitudinal direction with respect to the case body, and the take-out port is projected from the opening formed in the case body. Therefore, the outlet protrudes from the case body and is exposed. With the outlet exposed, turn the case body so that the opening of the outlet faces downward, and shake the case body vertically, and the granules in the housing will move into the outlet along the guide plate. It can be moved to remove granules from the outlet.

Japanese Unexamined Patent Publication No. 2005-178902

However, in the granular material storage container described in Patent Document 1, since the passage between the inclined surface of the guide plate and the take-out port has a size that allows one granular material to pass through, a plurality of granular materials can be passed through. If the passage is concentrated at the entrance of the passage, the passage may be clogged with granules.

An object of the present invention is to provide a granular material storage container in which a passage communicating with an outlet is not easily clogged in order to solve the above-mentioned problems in the prior art.

Among the means for solving the above problems, the main means of the present invention has a container body having a storage portion for accommodating granules inside and having a rectangular shape in a plan view, and the container body is the container. An outlet formed at one corner of the main body and capable of taking out the granules, and an induction portion formed in the accommodating portion to partition the passage of the granules from the inside of the accommodating portion to the outlet side. The outlet has an opening that opens along a direction intersecting each of the pair of side walls of the container body forming the corner in a plan view, and the guide portion has. In a plan view, the first guide portion having a first curved portion that is convex toward the inside of the accommodating portion from the side wall on one side forming the corner portion and extends toward the opening portion, and the corner. It has a second guide portion that protrudes inward from the side wall on the other side forming the portion, and the passage has the first guide portion and the second guide portion in a plan view. The second guide portion is formed between the two curved portions, which are convex toward the inside of the accommodating portion in a plan view, and the side opposite to the opening side of the second curved portion in a plan view. A granular material having a third curved portion which is connected to the end portion of the surface and extends to the opening side and the opposite side, and which is convex toward the side wall on the other side forming the corner portion. It is called a storage container.

The above configuration of the present application forms a corner portion with a first guide portion having a first curved portion that is convex toward the inside of the accommodating portion and extends from the side wall on one side forming the corner portion to the opening side. It has a second guide portion that protrudes inward from the side wall on the other side of the accommodating portion, and the second guide portion is a second curved portion that is convex toward the inside of the accommodating portion in a plan view. In a plan view, the third curved portion is connected to the end on the opposite side to the opening side and extends to the opening side and the opposite side, and is convex toward the side wall on the other side forming the corner portion. It has a curved portion. Therefore, when the posture of the container body is gradually tilted and the opening faces downward (vertically), the granules in the accommodating portion are at least one of the first curved portion and the second curved portion. It is guided toward the passage between the first curved portion and the second curved portion while being in contact with. Here, when a large number of granules are present in the accommodating portion, a large number of granules can be accumulated by the third curved portion. Therefore, it is possible to suppress the possibility that the granules accumulated on the side opposite to the opening side of the second curved portion move to the opening side at once. Therefore, it is possible to reduce the possibility that the particles are clogged in front of the passage.

Further, the radius of curvature of the second curved portion may be smaller than the radius of curvature of the first curved portion.

By making the radius of curvature of the second curved portion smaller than the radius of curvature of the first curved portion, the second curved portion becomes sharper in the inner direction of the container body as compared with the first curved portion. Therefore, in the second curved portion, the inclination of the curved surface on the opposite side to the opening side increases. For this reason, when the posture of the container body is gradually tilted and the opening faces downward (vertically), the granules accumulated on the side opposite to the opening side of the second curved portion are second curved. It can be difficult to get over the club.

Further, the end portion of the second curved portion on the opening side may be connected to a straight line portion extending linearly in a plan view, and the opening side of the straight line portion may extend toward the opening side in a plan view.

In this case, when the container body is tilted so that the opening faces downward and the granules move to the passage between the first curved portion and the second curved portion, the granules extend toward the opening side in a straight line. Move along the section. Therefore, it is possible to facilitate the inflow of the granular material into the opening.

Further, the straight portion may extend along the central axis of the opening in a plan view.

In this case, when the posture of the container body is gradually tilted so that the opening faces downward (vertically) and the granules move while falling along the straight line, the movement direction of the granules. Can be oriented along the central axis of the opening. Therefore, the inflow of the granular material into the opening can be facilitated.

Further, the container body has a rectangular shape in a plan view, and the first guide portion is formed inside the side wall on one side which is the short side of the container body, and the side wall on the other side which is the long side of the container body is formed. A second guide may be formed on the inside.

In this case, the first guide portion is formed inside the side wall on one side, which is the short side of the container body, and the second guide portion is formed inside the side wall on the other side, which is the long side of the container body. For this reason, when the posture of the container body is gradually tilted and the opening is directed downward (directed in the vertical direction) in a state where a large number of granules are present in the accommodating portion, the third curved portion of the second guide portion is used. Since a part of a large number of granules can be accumulated, it is possible to suppress the possibility that the granules accumulated on the side opposite to the opening side of the second curved portion move to the opening side at once. Therefore, it is possible to provide a granular material storage container that can further reduce the possibility that the granular material is clogged in front of the aisle.

According to the present invention, it is possible to provide a granular material storage container in which the passage communicating with the outlet is not easily clogged.

(Induction unit 50)
As shown in FIGS. 2 and 3, the guide portion 50 is formed in the accommodating portion 31 and forms a passage 75 for the granular material 80 from the inside of the accommodating portion 31 to the take-out port 40 side. The guide portion 50 has a first curved portion 56 that is convex inward from the second side wall 37 on one side (front side) of the corner portion 30a in a plan view toward the inside of the accommodating portion 31 and extends toward the opening 41 side. It has a first guide portion 55 and a second guide portion 60 projecting inward from the second side wall 37 on the other side (left side) forming the corner portion 30a to the accommodating portion 31. The passage 75 is formed between the first guide portion 55 and the second guide portion 60 in a plan view. In the present embodiment, the width b of the passage 75 increases as the passage 75 advances in the direction away from the opening 41 side, and the width b of the passage 75 becomes maximum at the entrance 75a of the passage 75. Further, the width b of the passage 75 is larger than the diameter φ of the granular material 80 and smaller than twice the diameter φ of the granular material 80.

Further, in the present embodiment, the first guide portion 55 is formed inside the second side wall 37 on the front side which is the short side side of the lower part 30 of the container body, and the second side wall on the left side which is the long side side of the lower part 30 of the container body.

It is connected to the second peripheral wall 35b in which the opening 41 is formed. The first curved portion 56 has a plate shape protruding upward from the bottom wall 35 of the container main body 29. Therefore, the first curved portion 56 has a first curved surface 56a facing inward of the accommodating portion. Granules 80 can move while contacting along the first curved surface 56a.

The top portion 56b of the first curved portion 56 is arranged at a position equivalent to that of the opening 41 in the Y-axis direction view.

(2nd induction unit 60)
As shown in FIG. 2, the second guide portion 60 is located inside the accommodating portion 31 with respect to the first curved portion 56 in a plan view, and the second curved portion 61 is convex toward the inside of the accommodating portion 31. And, in a plan view, it is connected to the end of the second curved portion 61 opposite to the outlet 40 side and extends to the rear side (opposite to the outlet 40 side), and the other side (left side) forming the corner portion 30a. It has a third curved portion 63 that is convex toward the second side wall 37 of the above. In the present embodiment, the second guide portion 60 has a second curved portion 61, a third curved portion 63, and a straight portion 65.

(Straight line part 65)
As shown in FIG. 2, the straight portion 65 has an opening 41 side extending toward the opening 41 side in a plan view. In the present embodiment, the straight portion 65 is connected to the second side wall 37 side on the left side of the second peripheral wall 35b'on the long side where one end side forms the opening 41. The straight portion 65 extends into the accommodating portion 31 along the central axis J of the opening 41. In the present embodiment, the straight line portion 65 extends in parallel along the central axis J.

The straight portion 65 has a plate shape protruding upward from the bottom wall 35 of the lower portion 30 of the container body. Therefore, the straight line portion 65 has a flat surface portion 65a facing the first curved portion 56 side in a direction orthogonal to the direction along the central axis J. The granules 80 can move while being in contact with each other along the flat surface portion 65a.

As shown in FIG. 1, the height of the straight portion 65 in the Z-axis direction has the same height as the fitting protrusion 37a. In the present embodiment, the axial length f of the straight line portion 65 has a size of about 1.8 times the diameter φ of the granular material 80.

(Second curved portion 61)
As shown in FIG. 2, the second curved portion 61 is connected to the other end side (rear side) of the straight portion 65, and the other end side extends toward the second side wall 37 on the left side of the lower portion 30 of the container body. The second curved portion 61 has a plate shape protruding upward from the bottom wall 35 of the lower portion 30 of the container body. Therefore, the second curved portion 61 has a second curved surface 61a facing inward of the accommodating portion 31. The granules 80 can move while being in contact with each other along the second curved surface 61a.

The top portion 61b of the second curved portion 61 is located between the opening 41 and the top portion 56b of the first curved portion 56 in the Y-axis direction view. Therefore, when the lower portion 30 of the container body is gradually tilted from the horizontal posture to the vertical posture and the opening 41 faces downward (the central axis J approaches the vertical line), it moves along the second curved surface 61a. The granules 80 can move over the top 61b, come into contact with the first curved surface 56a on the left side of the top 56a of the first curved surface 56a, and move toward the opening 41.

Here, the radius of curvature of the second curved portion 61 is smaller than the curvature of the first curved portion 56. Therefore, the bending condition of the second curved portion 61 is larger than the bending condition of the first curved portion 56. Therefore, the second curved portion 61 becomes sharper than the first curved portion 56, and the inclination of the curved surface on the side opposite to the opening 41 side of the second curved portion 61 increases. In the present embodiment, the radius of curvature r of the second curved portion 61 shown in FIG. 3 is 7.5 mm.

When the radius of curvature r of the second curved portion 61 is smaller than 6.0 mm, when the number of granules 80 is small, it may be difficult for the granules 80 to get over the second curved portion 61. Therefore, the radius of curvature r of the second curved portion 61 is preferably 6.0 mm or more.

Further, when the radius of curvature r of the second curved portion 61 is increased (for example, r = 9.0 mm), a large number of granules 80 easily get over the second curved portion 61, and the entrance 75a of the passage 75 is blocked and clogged. There is a risk that it will be easier. Therefore, the radius of curvature r of the second curved portion 61 is preferably 8.0 mm or less. Therefore, the radius of curvature r of the second curved portion 61 is preferably 6.0 mm or more and 8.0 mm or less.

(Third curved portion 63)
As shown in FIG. 2, the third curved portion 63 is connected to the end portion of the second curved portion 61 opposite to the opening 41 side and extends to the rear side (opposite side to the opening 41 side). , It becomes convex toward the second side wall 37 on the left side of the corner portion 30a. The third curved portion 63 has a plate shape protruding upward from the bottom wall 35 of the lower portion 30 of the container body. Therefore, the third curved portion 63 has a third curved surface 63a facing inward of the lower portion 30 of the container body. The granules 80 can move while being in contact with each other along the third curved surface 63a.

Since the third curved surface 63a is convex toward the second side wall 37 on the left side of the corner portion 30a, the third curved surface 63a is formed so as to be recessed on the left side. Therefore, when a large number of granules 80 are present in the accommodating portion 31, a large number of granules 80 can be stored by the third curved portion 63. Therefore, it is possible to suppress the possibility that the granules 80 accumulated on the opposite side (rear side) of the opening 41 side from the third curved portion 63 move to the opening 41 side at once. Therefore, when the container body 29 is gradually tilted from the horizontal posture to the vertical posture so that the opening 41 faces downward (the central axis J approaches the vertical line), the third curved portion 63 and the second curved portion 63 are bent. Combined with the portion 61, the granules 80 accumulated behind the second curved portion 61 can make it difficult to get over the top portion 61b of the second curved portion 61.

<Action / effect of this embodiment>
(Removal of granules 80 when a large number of granules 80 are present in the accommodating portion 31)
In the container main body 29 of the present embodiment, as shown in FIG. 3, the lid portion 45 of the outlet 40 is moved to the closed position Pt. When the opening 41 is covered with the lid 45, the container body 29 is gradually tilted from the horizontal posture to the vertical posture so that the opening 41 faces downward (the central axis J approaches the vertical line). When the opening 41 faces downward, a large number of granules 80 in the accommodating portion 31 are guided to the entrance 75a side of the passage 75 along the second curved portion 61. When the granules 80 pass through the entrance 75a, the plurality of granules 80 are guided into the passage 75 through the entrance 75a in a state of being connected in a direction along the central axis J. The granular material 80 that has moved into the passage 75 moves so as to fall toward the opening 41 along the straight line portion 65, and the granular material 80 that first moves in the passage 75 enters the insertion hole 48 of the lid portion 45. Moving. When the granular material 80 moves into the insertion hole 48, the lid portion 45 is rotated from the closed position Pt to the open position Ph (see FIG. 1A) to expose the opening 48a of the insertion hole 48 of the lid portion 45. .. Therefore, the granular material 80 can be taken out from the lid portion 45.

(Removal of the granular material 80 when a small number of the granular material 80 is present in the accommodating portion 31)
In the container main body 29 in the present embodiment, the lid portion 45 of the outlet 40 is moved to the closed position Pt. When the opening 41 is covered with the lid 45, the container body 29 is gradually tilted from the horizontal posture to the vertical posture so that the opening 41 faces downward (the central axis J approaches the vertical line). When the opening 41 faces downward, a small number of granules 80 in the accommodating portion 31 move toward the entrance 75a of the passage 75. At this time, the small number of granules 80 are guided to the entrance 75a side of the passage 75 while contacting at least one of the second curved portion 61 and the first curved portion 56. The granular material 80 that has moved to the entrance 75a side is guided into the passage 75 as it is through the entrance 75a. The granular material 80 that has moved into the passage 75 moves while falling toward the opening 41 along the straight line portion 65, and the granular material 80 that first moves in the passage 75 moves into the insertion hole 48 of the lid portion 45. do. When the granular material 80 moves into the lid portion 45, the lid portion 45 is rotated to the opening position Ph to expose the opening 48a of the insertion hole 48 of the lid portion 45. Therefore, the granular material 80 can be taken out from the lid portion 45.

As described above, when a large number of granules 80 are present in the accommodating portion 31, a large number of granules 80 can be stored by the third curved portion 63. Therefore, it is possible to suppress the possibility that the granules 80 accumulated on the side opposite to the opening 41 side of the second curved portion 61 move to the opening 41 side at once, so that the granules 80 are clogged in front of the passage 75. The risk can be reduced.

Further, by making the radius of curvature of the second curved portion 61 smaller than the radius of curvature of the first curved portion 56, the second curved portion 61 is sharper in the inner direction of the container body 29 as compared with the first curved portion 56. It becomes a state. Therefore, the inclination of the curved surface of the second curved portion 61 on the side opposite to the opening 41 side increases. Therefore, when the posture of the container body 29 is gradually tilted and the opening 41 faces downward (vertically), the granules 80 that collect on the side opposite to the opening 41 side of the second curved portion 61 are collected. Can make it difficult to get over the second curved portion 61.

Further, the end portion of the second curved portion 61 on the opening 41 side is connected to the straight portion 65 extending linearly in a plan view, and the opening 41 side of the straight portion 65 is directed toward the opening 41 side in a plan view. By extending the container body 29, the posture of the container body 29 is gradually tilted so that the opening 41 faces downward (vertically). When moving to the passage 75 between them, the granular material 80 moves while falling along the straight line portion 65. Therefore, the inflow of the granular material 80 into the opening 41 can be facilitated.

Further, the straight line portion 65 extends along the central axis J of the opening 41 in a plan view, so that the posture of the container body 29 is gradually tilted and the opening 41 faces downward (vertically). When the granular material 80 moves to the passage 75, the granular material 80 moves while falling along the straight line portion 65, and the moving direction of the granular material 80 is in the direction along the central axis J of the opening 41. can do. Therefore, the inflow of the granular material 80 into the opening 41 can be facilitated.

Further, the container body 29 has a rectangular shape in a plan view, and the first guide portion 55 is formed inside the second side wall 37 on the front side which is the short side side of the container body lower part 30, and the long side of the container body lower part 30 is formed. By forming the second guide portion 60 inside the second side wall 37 on the left side, which is the side, a large number of granules 80 can be stored by the third curved portion 63, and the granules 80 can be stored at once on the opening 41 side. It is possible to suppress the risk of moving to. Therefore, it is possible to provide the granular material storage container 1 that can further reduce the possibility that the granular material 80 is clogged in front of the aisle 75.

Although the configuration of the present invention and its action and effect have been described above with reference to Examples, the embodiments of the present invention are not limited to the above Examples.

For example, in the above-described embodiment, the axial length of the straight portion 65 has a size of about 1.8 times the diameter φ of the granular material, but the axial length of the straight portion 65 is granular. It may be at least twice the diameter φ of the object 80. Further, although the lid portion 45 that closes the opening portion 41 is connected via the hinge portion 43, the lid portion 45 may be detachably provided in the opening portion 41. Further, although the case where one granular material 80 is inserted into the lid portion 45 is shown, the lid portion 45 may be one into which two or more granular materials 80 can be inserted. The depth of the insertion hole 48 is made deeper.

The granular material storage container of the present invention is unlikely to clog the passage leading to the take-out port, and is expected to be widely used in the field of containers for storing locks, halitosis-preventing tablets, medicines, and the like.
