Further, it is more desirable if the material of the weight portion 123 and the elastic material used in the vicinity of the take-out hole 112 of the upper portion 11 of the container body are the same.
In this case, since the material forming the weight portion 123 is unified with the portion formed by the other elastic material of the household thin paper storage container 100, the household thin paper storage container 100 including the weight portion 123 is used. It can be integrally formed by injection molding (two-color molding). As a result, it is possible to suppress a decrease in productivity due to the provision of the weight portion 123.

On the other hand, although the productivity is lowered, the weight portion 123 is not integrally formed in this way, but is formed separately and then bonded with a predetermined adhesive, or the like, by an arbitrary method such as the lower part of the container body. It may be provided in 12. In this case, the material that can be used for the weight portion 123 does not need to be unified with the other parts of the household thin paper storage container 100, and the choice of the material used for the weight portion 123 can be expanded.

Further, as shown in FIGS. 3 to 5, it is desirable that the weight portion 123 is formed of the above elastic material so as to be exposed on the lower surface side of the lower portion 12 of the container body. In this case, the elastic material having a large frictional force as compared with the resin such as polyethylene and polypropylene forming the other part of the container body is exposed on the lower surface side of the lower part 12 of the container body, so that the thin paper storage container for household use is used. When 100 is placed, it can be made non-slip.

[Effect of embodiment]
According to the household tissue paper storage container 100 according to the embodiment, the container body 1 is composed of the container body upper part 11 and the container body lower part 12, and these are rotatably connected on the rear surface, so that the container can be connected. By rotating the upper part of the container body while it is placed on a table or the like, the storage space S can be opened and the household thin paper P can be refilled.
Therefore, when refilling the household thin paper P, it is not necessary to lift the household thin paper storage container 100, and the refilling operation can be performed while the household thin paper storage container 100 is placed on a table or the like.
Further, since the upper part 11 of the container body and the lower part 12 of the container body are connected on the rear surface, the positions of the upper part 11 of the container body and the lower part 12 of the container body do not need to be aligned one by one after the refilling of the household tissue paper P. These can be easily fitted to bring the container body 1 into a closed state.

Further, according to the household tissue paper storage container 100 according to the embodiment, the opening angle of the upper part 11 of the container body with respect to the lower part 12 of the container body is limited by the opening limiting means 14. As a result, when the container body 1 is opened, a gap can be secured between the upper surface of the opened upper part 11 of the container body and the mounting surface T on which the household thin paper storage container 100 is placed, so that the user can use the space. Since there is space left for the finger, it is easy to close it again.

In this case, as shown in FIG. 5, when the container body is opened, the upper surface of the upper portion 11 of the container body is fixed in a state where the upper surface thereof is not in contact with the mounting surface T on which the household thin paper storage container 100 is mounted. However, in this case, especially when the opening angle is 90 ° or more, the center of gravity is moved to the rear by the upper portion 11 of the container body, so that the household tissue paper storage container 100 tends to fall backward.
However, since the weight portion 123 is provided in the lower portion 12 of the container body, the household thin paper storage container 100 can be prevented from falling backward. Such an effect can be efficiently generated by providing the weight portion 123 in front of the lower portion 12 of the container body.

Further, in the household tissue paper storage container 100 according to the embodiment, as described above, when the household tissue paper P is taken out, the household tissue paper P is resisted in the take-out hole 112, and the internal household tissue paper P is reduced. However, when the weight of the container becomes light, the container itself is lifted by the resistance of the take-out hole 112, and it may be difficult to take out the household thin paper P.
According to the household thin paper storage container 100 according to the embodiment, the weight portion 123 makes the household thin paper storage container 100 heavier, so that even if the internal household thin paper P is reduced, it is prevented from being lifted. can do.

Further, when the weight portion 123 is formed of an elastic material that is also used in other parts of the household thin paper storage container 100, the household thin paper storage container 100 is integrally formed including the weight portion 123. Since the number of parts can be increased and the number of parts does not increase, the provision of the weight portion 123 does not cause a decrease in productivity.

Further, as shown in FIGS. 3 to 5, when the weight portion 123 is formed by an elastic material so as to be exposed on the lower surface side of the lower portion 12 of the container body, when the household thin paper storage container 100 is placed. It can also function as a non-slip portion to make it less slippery.

Further, according to the household thin paper storage container 100 according to the embodiment, when the user operates the first locking means 114 and the opening / closing lid 2 is unlocked, the opening / closing lid 2 is used by the first urging means 3. Is automatically flipped up, so that the opening / closing lid 2 can be easily opened when using thin paper for home use.
Further, when the user operates the second locking means 122 and the container main body upper portion 11 is unlocked with respect to the container main body lower portion 12, the container main body upper portion 11 is automatically flipped up by the second urging means 13. Therefore, when refilling the household thin paper P, the container body 1 can be easily opened.
Further, the first urging means 3 is formed of the same elastic material as the portion formed by other elastic members such as around the take-out hole 112 in the upper portion 11 of the container body and the opening / closing lid 2, and the container body 1 and the opening / closing are opened / closed. It can be integrally formed with the lid 2. Further, the second urging means 13 is formed of the same elastic material as the portion formed of the other elastic material in the upper portion 11 of the container body and the lower portion 12 of the container body, and may be integrally formed with the container body 1. can. Therefore, since it is not necessary to use different materials and the number of parts does not increase, the provision of the first urging means 3 and the second urging means 13 does not cause a decrease in productivity.

In particular, it is desirable that the periphery of the take-out hole 112 of the upper portion 11 of the container body is formed of an elastic material in order to apply appropriate resistance to the household thin paper P. According to the present embodiment, the first urging means 3 can be formed in a form continuous from the periphery of the take-out hole 112, and it is not necessary to separately arrange an elastic material from the periphery of the take-out hole 112. It is more preferable in terms of productivity.

Further, the main body side sealing ring portion 113 is formed on the upper portion 11 of the container body by the elastic material, and the opening / closing lid side sealing ring portion 22 is provided on the opening / closing lid 2 by the elastic material so as to be fitted when the opening / closing lid 2 is closed. It is possible to improve the airtightness of the take-out hole 112 and, by extension, the storage space S inside the container body 1. This effect can be particularly enhanced by the fact that both the main body side closed ring portion 113 and the opening / closing lid side closed ring portion 22 are formed of an elastic material.

Further, since the upper non-slip portion 115 is formed of the elastic material behind the opening / closing lid 2 on the upper surface of the container body 1, the stability of the opening / closing lid 2 at the time of opening can be improved.

Further, the upper fitting portion 116 is formed by the elastic material on the upper portion 11 of the container body, and the lower fitting portion 121 is formed by the elastic material on the lower portion 12 of the container body, and these are fitted when the container body 1 is closed. , The airtightness of the container body 1 can also be improved. This effect can be particularly enhanced by the fact that both the upper fitting portion 116 and the lower fitting portion 121 are formed of an elastic material.

In addition, the household thin leaf paper storage container 100 includes two types of resin materials (silicon rubber, elastic materials such as styrene-butadiene-based, polyester-based, polyethylene-based, and urethane-based thermoplastic elastomers, and polyethylene, polypropylene, and the like. It is made of a relatively hard material) and can be integrally formed by injection molding (two-color molding), so that it is also excellent in productivity.

[Modification example]
The shape and arrangement of the weight portion is not limited to the above. For example, as shown in FIG. 7, the weight portion 123A may be formed by integrally providing a portion formed of an elastic material on the entire lower surface of the lower surface of the lower portion 12A of the container body. In this case, as compared with the case where the weight portion is intensively provided in front of the lower part 12 of the container body, more elastic material is required and the productivity is lowered, but the entire lower surface of the lower part 12A of the container body is elastic. By being formed by the material, the effect as a non-slip can be improved.

The specific configuration of the opening limiting means is not limited to the above, as long as the opening angle of the upper portion 11 of the container body can be limited. For example, it may be formed on the inner surface side behind the container body so as to connect the upper part of the container body and the lower part of the container body with an elastic material.

Specifically, as shown in FIGS. 8 and 9, a first protrusion 118 projecting forward is provided on the rear inner surface side of the container body upper portion 11B, and on the rear inner surface side of the container body lower portion 12B. A second protrusion 124 that projects forward is provided.
Then, the opening limiting means 14A formed in a band shape by the elastic material is provided so as to connect the first protrusion 118 and the second protrusion 124, and as shown in FIG. 8, the upper portion 11B of the container body is closed. In the state, the opening limiting means 14A is folded so that it is stretched as the upper portion 11B of the container body is opened. Then, as shown in FIG. 9, when the opening limiting means 14A is on a substantially straight line when viewed from the Y direction, the opening limiting means 14A does not extend any more, so that the opening of the upper portion 11B of the container body is restricted in this state. The Rukoto. Further, when the upper portion 11B of the container body is closed, the opening limiting means 14A is folded again as shown in FIG.

In this way, the opening limiting means 14A formed in a band shape by the elastic material connects the first protrusion 118 provided on the upper portion 11B of the container body and the second protrusion 124 provided on the lower portion 12B of the container body. Therefore, the opening of the upper portion 11B of the container body can be restricted.
Further, the opening angle θ of the upper portion 11B of the container body can be determined by the length of the opening limiting means 14A.

According to such an opening limiting means 14A, since it is provided on the inner surface side of the container body 1B, it is not necessary to provide a protrusion or the like on the outer surface side, and the appearance of the household thin paper storage container 100B is not deteriorated.

Further, the opening limiting means 14A is formed of an elastic material as described above, one end thereof is connected to the first protrusion 118 provided on the upper portion 11B of the container body, and the other end thereof is provided on the lower portion 12B of the container body. It is connected to the second protrusion 124, which is bent when the upper portion 11B of the container body is closed.
Therefore, if the opening limiting means 14A is formed so as to be in a substantially linear state shown in FIG. 9 when viewed from the Y direction in a state where no force is applied, the container is formed as shown in FIG. When the upper portion 11B of the main body and the lower portion 12B of the container main body are closed and the opening limiting means 14A is folded, a force for returning to the state shown in FIG. 9 is generated. This makes it possible to urge the container body upper part 11B to rotate backward with respect to the container body lower part 12B with the connection portion between the container body upper part 11B and the container body lower part 12B at the rear as a rotation axis. Become.

That is, the opening limiting means 14A also functions as a urging means for urging the container main body upper portion 11B to the container main body lower portion 12B in the opening direction. Therefore, even if the second urging means 13 is not separately provided, when the user presses the second locking means 122 and the engaging convex portion 1221 and the engaging concave portion 117 are disengaged, the container main body is disengaged. The upper portion 11B can be rotated around the connection portion with the rear lower portion 12B of the container body as a rotation axis to open the storage space S.

In FIGS. 8 and 9, the case where the opening limiting means 14A is provided near the center in the Y direction behind the container body 1B is shown, but the specific forming position and the number of forming are not limited to this. .. For example, the opening limiting means 14A may be provided at a plurality of locations in the Y direction.

In addition, the configuration other than the weight portion and the opening limiting means of the household thin paper storage container 100 can be appropriately changed without departing from the gist of the present invention.

For example, as in the container body 1A shown in FIG. 7, the container body upper part 11A and the container body lower part 12A may be divided by a dividing line inclined so as to descend toward the front side in the X direction.
In this case, when the container body 1A is opened, the opening on the upper surface of the container body lower portion 12A becomes wider, which makes it easier to refill the household thin paper P.

Further, the upper part 11 of the container body and the lower part 12 of the container body are not necessarily limited to those in which the upper part 11 of the container body is urged by the second urging means 13, and the second urging means 13 is not particularly provided. The user may grasp the upper part 11 of the container body one by one by hand to open and close the container.

Further, the structure of the opening / closing lid 2 on the upper part of the container body is not limited to the one in which the illustrated opening / closing lid 2 is urged by the first urging means 3, and any structure can be adopted as long as the take-out hole 112 can be opened and closed. .. For example, the user may manually grasp the opening / closing lid 2 to open / close the opening / closing lid 2 without any particular urging means.

Next, the results of a test on whether the household thin paper storage container according to the embodiment of the present invention can be prevented from falling backward when the upper portion 11 of the container body is opened will be described.
