Mode for Carrying Out the Invention

[0016] Hereinafter, the toilet tissue storage container 100 which is an embodiment of the present invention will be described based on FIGS. 1 to 6. However, the technical scope of the present invention is not limited to the illustrated examples. In this specification, a numerical range described using "from" includes the numerical values described before and after it as the lower limit value and the upper limit value.

[0017] Also, in the following, as shown in FIG. 1, the X-axis, Y-axis, and Z-axis, as well as the front-back direction, left-right direction, and up-down direction, will be defined for explanation. That is, the side where the opening / closing lid 2 of the toilet tissue storage container 100 is provided is "up", the opposite side is "down", the side where the container body 1 and the opening / closing lid 2 are connected is "rear", the opposite side is "front", the right hand side in the state facing the rear direction is "right", the left hand side in the state facing the rear direction is "left", the axis along the front-back direction is the X-axis, the axis along the left-right direction is the Y-axis, and the axis along the up-down direction is the Z-axis.

[0018] [Configuration of Embodiment 1] As shown in FIGS. 1 to 4, the toilet tissue storage container 100 includes a container body 1 in which toilet tissue P is stored and has a take-out hole 1221 for taking out the toilet tissue P, and an opening / closing lid 2 connected to the container body 1 so as to be able to switch between a state of covering the take-out hole 1221 and a state where the take-out hole 1221 is exposed.

[0019] The toilet tissue P is, for example, a wet sheet impregnated with a chemical solution such as a wet tissue and rolled in a roll shape, and is stored in the container body 1 in a state of being rolled around an axis along the Z-axis direction. Further, perforations are formed in the toilet tissue P at regular intervals in the length direction, and the toilet tissue P separated along the perforations is to be used by the user.

[0020] [(1) Container Body] The container body 1 is the part of the toilet tissue storage container 100 that stores the toilet tissue P excluding the opening / closing lid 2, and includes a storage portion 11 and a lid body 12.

[0021] [a Storage Portion] The storage portion 十一 is a container for storing the toilet tissue P. As shown in FIGS. 1 to 4, it is formed in a bottomed cylindrical shape with an open top surface, and an opening 111 is provided on the entire top surface. Further, as shown in FIGS. 3 and 4, a male screw portion 112 is provided on the outer surface side of the upper end portion of the side surface along the circumferential direction.

[0022] For example, the storage compartment 11 can be made from materials such as PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), or ABS resin. Furthermore, the manufacturing method of the storage compartment 11 is not particularly limited and can be manufactured by methods such as injection molding or blow molding. The shape of the storage compartment 11 is preferably a cylindrical shape as described above, but it is not limited to this, as long as it can accommodate the sanitary tissue paper P. For example, it may be formed in a prism shape that is pentagonal, hexagonal, etc. in plan view.

[0023] [b Lid body] As shown in Figures 1 to 4, the lid 12 is a member that is attached above the storage section 11 so as to cover the opening 111, and comprises a lid body 121 and a flexible member 122.

[0024] [(a) Lid body] As shown in Figures 1 to 4, the lid body 121 is formed in a bottomed cylindrical shape with an open bottom surface, and a bottom opening 1211 is provided across the entire bottom surface. In addition, as shown in Figures 3 and 4, a female screw portion 1212 is provided along the circumferential direction on the inner surface of the lower end of the side surface.

[0025] The material used for the lid body 121 is the same as for the storage section 11; for example, PE, PP, PET, ABS resin, etc. can be used. Furthermore, the manufacturing method for the lid body 121 is not particularly limited and can be manufactured by methods such as injection molding or blow molding, similar to the storage section 11. The shape of the lid body 121 is not limited to a cylindrical shape; it can be formed to be the same shape as the storage section 11 in a plan view, depending on the shape of the storage section 11.

[0026] As shown in Figures 1 to 5, a recessed portion 1213 is formed in the center of the upper surface of the lid body 121, which is concave downwards. Furthermore, as shown in Figures 2 to 4, a planar bottom surface portion 12131 parallel to the XY plane is formed at the bottom of the recess 1213, an upper opening 12132 penetrating the upper surface of the lid body 121 is formed near the front end of the bottom surface portion 12131, and a recessed portion 12133 extending further downward from the bottom surface portion 12131 is formed near the rear end of the bottom surface portion 12131.

[0027] [(b) Flexible member] As shown in Figures 1 and 3 to 5, the flexible member 122 is a membrane-like member made of a flexible material that is attached to the lid body 121 so as to cover the entire bottom surface 12131 of the recess 1213. As for the material used to form the flexible member 122, any material that has enough flexibility to be stretched and change shape when the opening / closing lid 2 is closed and pressed by the projection 22, as described later, can be used. For example, silicone rubber or thermoplastic resins such as styrene-butadiene, polyester, polyethylene, or urethane can be used, but silicone rubber is particularly preferred because it can be deformed with less force. Furthermore, the hardness of the flexible member 122 is preferably between 20 and 90. The above hardness values ​​were measured according to JIS K 6253-3:2012 (Type A durometer). Furthermore, the thickness (length in the Z-axis direction) of the flexible member 122 is preferably between 1 mm and 5 mm.

[0028] Near the front end of the flexible member 122, at a position corresponding to the upper opening 12132 of the lid body 121 (a position that overlaps with the upper opening 12132 in a plan view), as shown in Figures 1 and 3 to 5, an extraction hole 1221 is formed, which is a hole for removing the sanitary tissue paper P stored inside the container body 1, by penetrating the flexible member 122.

[0029] As shown in Figure 5, the removal hole 1221 is located in a plan view on the upper surface of the lid 12, in the center in the Y-axis direction and in the X-axis direction, closer to the front end than the center. The removal hole 1221 is formed to have an elliptical shape, with its major axis parallel to the X-axis and its minor axis parallel to the Y-axis. Preferably, its dimensions are 10 mm to 20 mm in the major axis direction (X-axis direction) and 0.5 mm to 2 mm in the minor axis direction (Y-axis direction).

[0030] The removal hole 1221 is formed in the flexible member 122, which allows for appropriate resistance to be applied to the sanitary tissue paper P, making it easy to tear off the sanitary tissue paper P along the perforations and to hold the next sheet of sanitary tissue paper P with its end protruding from the removal hole 1221.

[0031] [(2) Opening and closing lid] The opening / closing lid 2 is a component that is rotatably attached to the lid body 121 of the lid 12 of the container body 1, and as shown in Figures 1 to 4, it comprises an opening / closing lid body 21, a projection 22, and an annular wall portion 23. The material for the opening / closing lid 2 can be the same as that used for the storage section 11 of the container body 1 and the lid body 121 of the lid 12, for example, PE, PP, PET, ABS resin, etc. Furthermore, the manufacturing method for the opening / closing lid 2 is not particularly limited and can be manufactured by methods such as injection molding, blow molding, etc., similar to that used for the storage section 11 of the container body 1 and the lid body 121 of the lid 12.

[0032] [a Opening / closing lid body] As shown in Figures 1 to 4, the opening and closing lid body 21 is a flat, plate-shaped member whose one end is rotatably connected to the center in the Y-axis direction near the rear end of the recess 1213 of the lid body 121 of the lid body 12 of the container body 1.

[0033] The opening / closing lid body 21 has a shape in plan view that is substantially the same as the shape of the recess 1213 in plan view, except for the front end. When the rear end connected to the lid body 121 is pivoted and made parallel to the XY plane, it is configured to fit into the recess 1213 and be fixed in place, as shown in Figure 4. The state in which the opening / closing lid body 21 is fitted into the recess 1213 is considered the closed state, and the state in which the opening / closing lid body 21 is not fitted into the recess 1213 is considered the open state.

[0034] As described above, the removal hole 1221 is formed in the flexible member 122 provided in the recess 1213. Therefore, when the container is closed, the removal hole 1221 is covered by the opening / closing lid 2, and when it is open, the removal hole 1221 is exposed. If the removal hole 1221 is not visible from outside the sanitary tissue storage container 100, it is assumed that the removal hole 1221 is covered by the opening / closing lid 2. If the removal hole 1221 is visible from outside the sanitary tissue storage container 100, it is assumed that the removal hole 1221 is exposed.

[0035] [b Projection] As shown in Figures 1 to 4, the projection 22 is a portion that protrudes downward from the opening / closing lid body 21, and is located on the lower side of the opening / closing lid 2 when it is in the closed state.

[0036] As shown in Figures 1 to 4, the projection 22 is formed in the central part of the Y-axis direction near the rear end of the opening / closing lid body 21 when the opening / closing lid 2 is in the closed state, that is, in the closed state, it is positioned opposite to the recessed portion 1213 formed in the recess 1213 of the lid body 121 of the lid body 12 of the container body 1.

[0037] The projection 22 is formed such that, when the lid 2 is in the closed state, the length of the projection 22 that protrudes downward from the lower surface of the lid body 21 is longer than the distance between the lower surface of the lid body 21 and the upper surface of the flexible member 122 when the lid 2 is in the closed state, as shown in Figure 4. This causes the portion of the flexible member 122 located above the recessed portion 12133 to be pushed downward when the lid 2 is in the closed state.

[0038] Specifically, the projection 22 is preferably formed to protrude from the lower surface of the opening / closing lid body 21 by a length of 1 mm to 20 mm, which is longer than the distance between the lower surface of the opening / closing lid body 21 and the upper surface of the flexible member 122, so that when the opening / closing lid 2 is closed, it pushes the flexible member 122 downward by that length.

[0039] As described above, the projection 22 is located in the center of the Y-axis direction near the rear end of the opening / closing lid body 21 when the opening / closing lid 2 is in the closed state. As a result, the projection 22 pushes downward the position of the flexible member 122 behind the outlet hole 1221, that is, the position in the long axis direction of the outlet hole 1221, which is formed to be an ellipse with its long axis parallel to the X-axis and its short axis parallel to the Y-axis.

[0040] [c Annular wall section] As shown in Figures 1 to 4, the annular wall portion 23 is a portion that protrudes downward in an annular shape from the opening / closing lid body 21, and is provided on the lower side of the opening / closing lid 2 when it is in the closed state.

[0041] As shown in Figure 4, the annular wall portion 23 is formed such that, when the opening / closing lid 2 is in the closed state, the length that protrudes downward from the lower surface of the opening / closing lid body 21 is equal to the distance between the lower surface of the opening / closing lid body 21 and the upper surface of the flexible member 122 when the opening / closing lid 2 is in the closed state. As a result, when the opening / closing lid 2 is in the closed state, the annular wall portion 23 comes into contact with the flexible member 122 without pressing it down. Furthermore, as shown in Figure 4, the annular wall portion 23 is formed in a position that surrounds the outlet hole 1221 and contacts the flexible member 122 when the opening / closing lid 2 is in the closed state.

[0042] [2 Effects of the Embodiment] In the sanitary tissue paper storage container 100 according to this embodiment, the opening / closing lid 2 is equipped with a projection 22. When the opening / closing lid 2 is in the open state, the projection 22 does not press against the flexible member 122, but when the opening / closing lid 2 is in the closed state, it presses against the flexible member 122 and pushes it downwards. Furthermore, when the opening / closing lid 2 is in the closed state, the projection 22 presses against the position in the long axis direction of the removal hole 1221 of the flexible member 122, which is formed to have an elliptical shape with its long axis parallel to the X axis and its short axis parallel to the Y axis.

[0043] As a result, when the opening / closing lid 2 is in the closed position, the flexible member 122 is stretched in the X-axis direction, and consequently, as shown in Figure 5, the elliptical-shaped outlet hole 1221 is stretched in its long axis direction, resulting in an elliptical shape that is longer in the long axis direction and shorter in the short axis direction compared to when the opening / closing lid 2 is in the open position.

[0044] Therefore, the area of ​​the outlet hole 1221 changes depending on whether the opening / closing lid 2 is in an open state (when the outlet hole 1221 is exposed) or in a closed state (when the outlet hole 1221 is covered by the opening / closing lid 2). When the opening / closing lid 2 is in a closed state, the area of ​​the outlet hole 1221 becomes smaller compared to when the opening / closing lid 2 is in an open state. As a result, when the sanitary tissue paper storage container 100 is in use, the area of ​​the outlet hole 1221 is widened to maintain ease of removal of the sanitary tissue paper P, while when the sanitary tissue paper storage container 100 is not in use, the area of ​​the outlet hole 1221 is narrowed to prevent the liquid impregnated in the sanitary tissue paper P from volatilizing through the outlet hole 1221.

[0045] Furthermore, since the area of ​​the dispensing hole 1221 can be automatically changed in conjunction with the opening and closing of the opening / closing lid 2, the effort required to change the area of ​​the dispensing hole 1221 can be reduced compared to, for example, a case where the user has to manually change the area of ​​the dispensing hole 1221 each time.

[0046] Furthermore, the projection 22 is provided near the rear end of the opening / closing lid body 21 in the closed state, which is close to the pivot point of the opening / closing lid 2's rotation. When the opening / closing lid 2 is closed, the projection 22 is configured to press against the portion of the flexible member 122 located behind the outlet hole 1221, which is closer to the connection point between the opening / closing lid 2 and the lid body 121, which is the pivot point of the opening / closing lid 2's rotation, compared to the outlet hole 1221. This reduces the force required to close the opening / closing lid 2 and push the flexible member 122 in with the projection 22.

[0047] [3 Variations] In the above description of the configuration, the removal hole 1221 is provided near the front end of the flexible member 122, and the projection 22 is provided near the rear end of the opening / closing lid body 21 when it is closed, and when the opening / closing lid 2 is closed, the projection 22 presses against the part of the flexible member 122 located behind the removal hole 1221. However, conversely, the projection 22 may be configured to press against the part of the flexible member 122 located in front of the removal hole 1221.

[0048] Specifically, for example, as shown in Figure 6, a sanitary tissue storage container 100A may be provided with an outlet hole 1221A near the rear end of the flexible member 122A, and the opening / closing lid 2A may be provided with a projection 22A near the front end of the lower side when closed.

[0049] In this case, since the projection 22A presses against the portion located in front of the outlet hole 1221A, which is spaced apart from the connection point between the opening / closing lid 2A and the lid body 121A (the pivot point for the rotation of the opening / closing lid 2A), compared to the outlet hole 1221A, it is undesirable in that the force required to close the opening / closing lid 2A and push in the flexible member 122A by the projection 22A becomes larger. However, when closing the opening / closing lid 2A, the timing at which the projection 22A begins to push in the flexible member 122A can be delayed. [Explanation of Symbols]
