As shown in FIG. 2, the household thin paper storage container 10 stores, for example, a household thin paper P made of roll paper such as a wet sheet or a wet tissue wound in a roll shape on the inside. The container main body 20 in which a take-out portion 41 as an outlet for taking out the household thin paper P is formed, and a small lid as a lid attached to the container main body 20 so as to open and close the take-out portion 41 by rotation. 50 and two support portions 60 and 60 that rotatably support the small lid 50 with respect to the container body 20.
The household thin paper P wound in a roll shape and stored in the household thin paper storage container 10 is provided with perforations P1 at regular intervals in the length direction, and the size separated along the perforations. The user's home thin paper P is used by the user.

(Container body)
The container body 20 includes a bottomed cylindrical bottle 30 that forms the lower part of the container body 20 and a lid 40 that forms the upper part of the container body 20.

As shown in FIG. 2, the bottle 30 has a substantially constant cylindrical shape from the bottom portion to the vicinity of the upper end portion, and the upper end portion 31 is formed to have a slightly small diameter and has a large opening. A male thread portion is formed on the outer peripheral surface of the upper end portion 31 of the bottle 30 along the circumferential direction. In addition, illustration of the lower part (bottom part) of the bottle 30 is abbreviate | omitted.
Since the bottle 30 has a cylindrical shape, the above-described roll-shaped household thin paper P can be disposed and stored in a substantially concentric position. Further, the household thin paper P is adapted to feed out a piece of paper from the center side of the roll.
The bottle 30 is integrally formed by die molding such as injection molding or blow molding using a thermoplastic resin such as PE (polyethylene), PP (polypropylene), or PET (polyethylene terephthalate). .

The lid 40 has a cylindrical shape that is shorter than the bottle 30, and the upper end side thereof is closed by the top surface part 42 and the lower end part is opened. Further, the outer diameter of the lid 40 is substantially equal to the outer diameter of the bottle 30, and a female screw portion that is screwed into the male screw portion of the bottle 30 is formed on the inner peripheral surface thereof. With this female screw portion, the lid 40 can be attached to and detached from the upper end portion 31 of the bottle 30 described above.
Since the lid 40 is detachable, the household thin paper P can be filled in the bottle 30 when it is detached from the bottle 30, and the household thin paper P inside when the lid 40 is attached to the bottle 30. It is possible to hold the roll so as not to go out.
The lid 40 is integrally formed by mold molding such as injection molding or blow molding using a thermoplastic resin such as PE, PP, or PET.

Moreover, a substantially square-shaped recess 43 corresponding to the outer shape of the small lid 50 described above is formed at the center of the top surface portion 42 of the lid 40 that forms a part of the container body 20, and fits into the recess 43. Thus, the small lid 50 is attached to the top surface portion 42.
A cylindrical portion 44 is erected at the central portion of the recess 43, and an extraction portion 41 for taking out the household thin paper P one by one is provided at the inner center thereof. At the upper end of the cylindrical portion 44, a flange-like locking portion 44a protruding outward is formed, and can be locked when the small lid 50 is closed.

As shown in FIGS. 1 and 2, the take-out portion 41 is attached to an attachment hole formed through the inner bottom surface inside the cylindrical portion 44. The extraction part 41 integrally connects the cylinder and the hemispherical shell, and forms an opening at the top of the upper hemispherical shell. The extraction portion 41 is a substantially dome-shaped member that is elastically deformable and is formed of, for example, silicon rubber. Then, the household thin paper P is passed through the top opening from below to give an appropriate sliding resistance, and by pulling the domestic thin paper P from above, separation from the perforations can be made one by one. Further, the sliding resistance at the opening of the take-out portion 41 has a function of holding the separated household thin paper P in the take-out portion and easily taking out the next.
Note that two flange portions are formed in the lower half of the cylindrical portion of the extraction portion 41 so that the flange portions are positioned above and below the mounting holes on the inner bottom surface of the cylindrical portion 44. Thus, the extraction part 41 is held in the mounting hole.

(Small lid)
The small lid 50 is rotatably attached to the inner bottom surface of the concave portion 43 of the lid 40 via two support portions 60, 60, and opens and closes the extraction portion 41 by turning around the Y axis. ing.
As shown in FIG. 1, the small lid 50 is formed in a substantially square flat plate shape and can be fitted into the concave portion 43 of the lid 40.
In addition, a cylindrical portion 53 having a slightly larger inner diameter than the cylindrical portion 44 formed in the concave portion 43 of the lid 40 is formed on the back surface (the lower surface when closed) of the small lid 50. At the lower end of the cylindrical portion 53, a locking portion 53a that protrudes inward is formed over the entire circumference. When the small lid 50 is closed, the cylindrical portion 44 of the lid 40 enters inside the cylindrical portion 53, and the locking portions 44a and 53a engage with each other to hold the small lid 50 in a closed state. .
Similar to the lid 40, the small lid 50 is integrally formed by mold molding such as injection molding or blow molding using a thermoplastic resin such as PE, PP, or PET. Therefore, since the small lid 50 and the lid 40 are flexible to each other, they can be easily disengaged by pulling the front end portion of the small lid 40 upward.

(Support part)
FIG. 3 is a perspective view of the support portion 60 with a part of the small lid 50 cut away, and FIG. 4 is a cross-sectional view of the support portion 60 along the XZ plane.
The two support portions 60, 60 are respectively disposed on the lower side of the front end portion and the lower side of the rear end portion of the small lid 50, and rotate the small lid 50 about the rotation axis along the Y-axis direction that is not on the same line. It is possible to support the cap 40 and the support portions 60 and 60 so that the connection between the lid 40 and the small lid 50 can be released.
That is, when the small lid 50 is rotated by the front support portion 60, the rear support portion 60 is disconnected, and when the small lid 50 is rotated by the rear support portion 60, the front support portion 60 is connected. By releasing this, it is possible to open the front end side of the small lid 50 and to open the rear end side.

  Each support portion 60 includes a support shaft 61 fixedly installed along the Y-axis direction on the front and rear sides of the cylindrical portion 44 on the inner bottom surface of the concave portion 43 of the lid 40, and the rear surface (lower surface) of the small lid 50. ) In the front side and the rear side in the Y-axis direction.

The two support shafts 61 are in the form of round bars formed in parallel along the Y-axis direction, and leg columns 61 a are formed below the support shafts 61. With this pedestal 61a, the support shaft 61 is positioned somewhat above the inner bottom surface of the recess 43, so that the shaft holder 62 and the inner bottom surface of the recess 43 do not interfere with each other when the small lid 50 is rotated. Yes. The shaft portion 61 and the pedestal column portion 61a are integrally formed of the same material with respect to the lid 40.
Note that when the rotation range of the small lid 50 is sufficiently secured, the pedestal portion 61a may not be formed.

Each shaft holder 62 protrudes downward on the lower surface of the small lid 50 and has a structure that holds the support shaft 61 by two claws 61a formed along the Y-axis direction so as to be rotatable. The space between the two claws 62a is a groove-shaped recess along the Y-axis direction. The two claws 62 a are integrally formed of the same material with respect to the small lid 50.
An inner peripheral surface that is slidably in contact with the outer periphery of the support shaft 61 is formed inside the recess between the two claws 62a.
As shown in FIG. 4, these two claws 62 a are formed so as to hold at least a range wider than 180 ° of the outer peripheral surface of the support shaft 61. The shaft holder 62 can be connected to the support shaft 61 so as to be rotatable around the support shaft 61 and can be separated by utilizing the flexibility of the materials of the two claws 62a. Yes. For example, when the front end portion or the rear end portion of the small lid 50 is pulled with one hand, the shaft holder 62 of the support portion 60 closer to the end portion may be connected with a holding force that can be easily removed from the support shaft 61. . For this reason, as shown in FIG. 4, the two claws 62a are formed so as to be held within a range not greatly exceeding 180 ° of the outer peripheral surface of the support shaft 61.

  The two shaft holders 62 are provided on the lower surface of the small lid 50 so as to be equal to the distance between the two support shafts 61 in the X-axis direction. 61 and the shaft holder 62 can be connected (a state where the small lid 50 is closed).

(Explanation of effects when using household thin paper storage containers)
Next, the handling at the time of use of the household thin paper storage container 10 mentioned above is demonstrated. FIG. 5 is an operation explanatory view showing a state in which the small lid 50 is opened.
First, the front end of the small lid 50 shown in FIGS. The top surface portion 42 of the lid 40 is formed with semicircular recesses 45, 45 adjacent to the concave portion 43 on the front side and the rear side, respectively, so that the rotation operation with respect to the front end portion and the rear end portion of the small lid 50 can be performed. Making it easy.
By this turning operation, in the support portion 60 on the front end side, the interval between the claws 62a of the shaft holder 62 is widened to disengage the support shaft 61, and the connection state between the front end side of the small lid 50 and the lid 40 is released. . Then, the small lid 50 rotates around the Y axis about the support shaft 61 of the support portion 60 on the rear end side, and the cylindrical portion 44 of the lid 40 is detached from the cylindrical portion 53 on the small lid 50 side, and FIG. As shown, the front side of the small lid 50 is opened.
After the internal thin paper P is pulled out from the take-out portion 41 and used, when the front end portion of the small lid 50 is pushed down, it rotates around the Y axis about the support shaft 61 of the support portion 60 on the rear end side. Thus, the cylindrical portion 44 enters the cylindrical portion 53, and the support shaft 61 is pushed into the shaft holder 62 of the support portion 60 on the front end side to be connected again, and the small lid 50 is closed.
Further, when opening from the rear with respect to the household thin paper storage container 10, the rear end portion of the small lid 50 is pulled up, and the small lid 50 rotates about the support shaft 61 of the support portion 60 on the front end side. The shaft holder 62 of the support portion 60 on the rear end side is detached from the support shaft 61, and the rear side of the small lid 50 is opened. After the use of the household thin paper P, the rear end portion of the small lid 50 is pushed down to rotate around the support shaft 61 of the support portion 60 on the rear end portion side and into the shaft holder 62 of the support portion 60 on the front end portion side. The support shaft 61 is pushed in and connected again, and the small lid 50 is closed.

As described above, in the household thin paper storage container 10, the rotation support shafts 61, 61 of the small lid 50 are arranged on the front end side and the rear end side, and each support portion 60 is connected to the support shaft 61 and the shaft. Since the hugging 62 can be attached and detached, the small lid can be rotated around the rear end side center and the front end side center, respectively, and the small lid 50 can be opened to the front side and the rear side. Therefore, not only the person on the front side with respect to the household thin paper storage container 10 but also the person on the rear side can open the small lid 50 without changing the orientation of the household thin paper storage container 10, and more easily. Household thin paper can be taken out.
Further, since the support shaft 61 and the shaft holder 62 can be attached and detached by utilizing the flexibility of the material constituting each support portion 60, the support member 60 can be separated only by the pulling operation of the lid 50. The lid 50 can be easily rotated around an arbitrary axis, and the household thin paper P can be taken out more easily.

(Other)
In the example of the household thin paper storage container 10 described above, the two rotation support shafts 61 and 61 of the small lid 50 are parallel to each other and arranged on the front end side and the rear end side of the small lid. The arrangement of the support shafts is not limited to the front and rear ends, and the support shafts are not limited to being parallel to each other. Three or more support portions 60 may be provided.
For example, support portions 60 may be provided at the left end and the right end of the small lid so that the small lid 50 can be opened in all directions. In that case, the small lid 50 rotates around the support shaft 61 of the support portion 60 located on the opposite side of the direction in which the small lid 50 is to be opened, and the other support portions 60 are all released from the connected state.
Further, the shape of the small lid 50 is not limited to a square shape, and may be a circular shape, a polygonal shape, or other various graphic shapes.
Note that the arrangement of the support portion 60 with respect to the small lid 50 is desirably in the vicinity of the outer edge portion of the small lid 50. For example, when the small lid 50 is disposed on the inner side far from the outer edge portion, the end opposite to the opening side when the small lid 50 is rotated may interfere with the upper surface of the lid body 40.

Moreover, in each support part 60, although the example in which the shaft holder 62 surface-contacts with the peripheral surface with respect to the support shaft 61 was shown, it is not the whole surface, for example, but the two shaft-shaped claw parts are made to oppose. For example, a structure in which a plurality of points or a plurality of lines contact each other may be used.
Further, for each support portion 60, the support shaft 61 is disposed on the lid 40 side and the shaft holder 62 is disposed on the small lid 50 side. However, the shaft holder 62 is provided on the lid 40 side, and the support shaft is provided on the small lid 50 side. 61 may be provided.

  Further, the support unit 60 is not limited to the above structure as long as it can be rotated and detached. For example, as shown in FIG. At each of the front and rear ends, the substantially hemispherical protrusions 61a and 61a are arranged so as to protrude outward from each other along the Y-axis direction serving as the rotation axis, and have recesses into which the protrusions 61a and 61a are fitted. The two receiving portions 62a and 62a may be provided on the inner bottom surface of the recess 43 of the lid 40 and held so as to be sandwiched between them. In the case of such a configuration, when the end portion of the small lid 50 is pulled upward, the receiving portions 62a are spread outwardly and the projections 61a and 61a are detached. Also in this structure, the protrusions 61a and 61a may be disposed on the lid 40 side so as to face each other, and a recess serving as a receiving portion may be provided on the small lid 50 side.

Further, as shown in FIG. 7, the claw 62 a is formed in an arc shape for each support portion 60 (both the two claws 62 a are illustrated in an arc shape in FIG. 7, but are rotated when the small lid 50 is opened. Only one claw 62a (the claw on the right side in the figure) that moves to the lid 40 side needs to be arcuate), and the small lid 50 is rotated in the opening direction to move toward the lid 40 side. A holding hole 63 into which one of the claws 62 a enters may be provided on the inner bottom surface of the recess 43 of the lid 40.
That is, when the small lid 50 is opened, the one claw 62a of the support portion 60 on the rotation shaft side enters the holding hole 63 when the small lid 50 is opened. It is possible to prevent the shaft holder 62 and the support shaft 61 from being accidentally detached.

  Moreover, although the case where the household thin paper storage container 10 stores the roll-shaped household thin paper P has been illustrated, for example, the household thin paper P that has been cut one by one is folded substantially in half, and alternately stacked and stored. In this case, the household thin paper storage container 10 can be applied. In this case, the container body 20 is more preferably a rectangular parallelepiped shape.

(Second embodiment)
A second embodiment of the support portion will be described with reference to FIG.
The support portion 60 described above has a structure in which one support shaft 61 and a shaft holder 62 are provided for one rotation axis. However, in the second embodiment, as shown in FIG. Two (or more) support shafts 61A and shaft holders 62A are provided.
In that case, each holding part 60A arranges two support shafts 61A whose length in the Y-axis direction is shortened so as to be on the same axis on the inner bottom surface of the recess 43 of the lid 40 (for example, the angular position of the recess 43). ) A shaft holder 62 </ b> A whose length in the Y-axis direction is similarly shortened is disposed at each corresponding position on the lower surface side of the small lid 50. That is, in this example, a set of the support shaft 61A and the shaft holder 62A is arranged at the four corners of the small lid 50.
The support portion 60A having such a configuration also functions in the same manner as the support portion 60 described above, and the same effects can be obtained.
Also in this example, the shaft holder 62A may be provided on the lid 40 side, and the support shaft 61A may be provided on the small lid 50 side.

(Third embodiment)
A third embodiment of the support portion will be described with reference to FIG.
The support unit 60 described above is configured such that the support unit 60 can rotate around the axis along a certain direction (Y-axis direction). In the third embodiment, as shown in FIG. Each support portion 60B has a spherical bearing structure, and each support portion 60B is configured to be rotatable about all directions.
FIG. 9 is a cross-sectional view of the support portion 60B along the XZ plane. The support portion 60B includes a sphere portion 61B that is erected from the inner bottom surface of the concave portion 43 of the lid 40 via a pedestal portion 63B, and a sphere holding portion 62B that is provided on the lower surface of the lid body 50. .

The spherical portion 61B is a spherical body having a smooth spherical surface.
The spherical body holding portion 62B has a cylindrical shape as a whole along the Z-axis direction, and a spherical body receiving surface that is in surface contact with the spherical surface is formed therein. In addition, the spherical body holding portion 62B holds the spherical body portion 61B so as to include the upper half or more of the range, like the shaft holder 62 described above. And the spherical body holding | maintenance part 62B is cut | disconnected 64B toward the upper direction from the lower end part. Thereby, the cylindrical sphere holding part 62B can be increased in diameter toward the outside in the radial direction, whereby the sphere part 62B can be pulled out from the sphere holding part 62B.

Further, the support portion 60B becomes four intersections of two rotation axes S _X and S _X parallel to the X axis direction and two rotation axes S _Y and S _Y parallel to the Y axis direction. Accordingly, the rotation axes S _X and S _X parallel to the two X-axis directions and the rotation axes S _Y and S _Y parallel to the two Y-axis directions are small. The lid 50 can be rotated. When rotating around any one of the four axes, the support part 60B other than the two support parts 60B on the axis is separated from the sphere part 61B and the sphere holding part 62B, The small lid 50 is rotated by the two support portions 60B.

Also in the case of the support portion 60B having such a configuration, it functions in the same manner as the support portion 60 described above, and the same effect can be obtained.
Furthermore, since the support portion 60B is shared by two axes as compared with the case where the support portions 60B are provided at both ends of one rotation axis, the required number of individuals is reduced and the production of household thin paper storage containers is achieved. It becomes possible to reduce the cost and improve the productivity.
Further, since the spherical bearing is rotatable about any direction, even when two support portions 60B are provided for one rotation axis, the processing accuracy for aligning the rotation axes is not required to be high, and the container The processing cost can be reduced. Or even when manufactured with the same processing accuracy as before, the small lid 50 can be rotated more smoothly.
Also in this example, the spherical body holding portion 62B may be provided on the lid 40 side, and the spherical body portion 61B may be provided on the small lid 50 side.
