[0014] Hereinafter, an embodiment of a sanitary tissue paper storage container according to the present invention will be described in detail with reference to the drawings. However, the embodiment described below is subject to various technically preferable limitations for carrying out the present invention, but the scope of the present invention is not limited to the following embodiment and illustrated examples. In the following description, the front-to-back, left-to-right, and up-to-down directions as well as the X-axis, Y-axis, and Z-axis are defined as shown in Fig. 1. That is, in the sanitary tissue paper storage container 100, the side from which the sanitary tissue paper is taken out is the top, the opposite side is the bottom, the near side in a plan view of the sanitary tissue paper storage container 100 is the front, the opposite side is the rear, the right hand side when the front of the container is viewed from the front is the right, and the left hand side when the front of the container is viewed from the front is the left, and the axis along the front-to-back direction is the X-axis, the axis along the left-to-right direction is the Y-axis, and the axis along the up-to-down direction is the Z-axis.

[0015] <Configuration of the embodiment> (Overall composition) As shown in Figures 1 to 3, the sanitary tissue paper storage container 100 is configured to include a container body 1 that stores rolled sanitary tissue paper P inside, a lid body 2 that can be removably attached to the container body 1, and an extraction portion 3 that can be removably attached to the lid body 2. The lid body 2 is configured to be detachable from the container body 1, so that with the lid body 2 removed from the container body 1, sanitary tissue paper can be stored inside the container body 1 or removed from the inside.

[0016] (hygienic tissue paper) The sanitary thin paper P is, for example, rolled paper such as wet sheets or wet tissues wound in a roll. The sanitary thin paper P is stored in the container body 1 in a rolled state with the axis of the sanitary thin paper P aligned in the vertical direction, as shown in Fig. 3. In other words, the container body 1 stores the sanitary thin paper P in an orientation in which the axis of the sanitary thin paper P is substantially perpendicular to the bottom surface of the container body 1. The sanitary thin paper P stored in this container body 1 is pulled out from the center side of the roll and taken out through the take-out section 3. The sanitary thin paper P has perforations P1 at regular intervals along its length, and the user is allowed to use the sanitary thin paper P that has been cut off along the perforations P1.

[0017] (Container body) The container body 1 is a container formed in a cylindrical shape with a bottom, and has an opening 1a on the top surface. Sanitary tissue paper P is placed inside the container body 1 through this opening 1a. As shown in FIG. 2, a male screw portion 11 is provided on the outer peripheral surface of the container body 1 near the opening 1a in the circumferential direction. The container body 1 is formed from, for example, PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), ABS resin, or the like. The container body 1 is formed in a cylindrical shape having a circular shape with a diameter of 50 mm to 200 mm in plan view, a Z-axis direction (height) of 45 mm to 200 mm, and a thickness of each side of 0.5 mm to 10 mm.

[0018] (protrusion) 2, a plurality of protrusions 12 are provided on the inner surface of the container body 1. The plurality of protrusions 12 are provided on the container body 1 by integral molding. The projection 12 here has a generally conical shape, with the tip end being tapered. The height of the protrusion 12 having a substantially conical shape is 0.5 mm to 2.5 mm. The protrusions 12 are provided to impart a predetermined frictional resistance to the sanitary thin paper P stored in the container body 1 when the sanitary thin paper P comes into contact with the inner surface. When the rolled sanitary thin paper P comes into contact with the inner surface of the container body 1, the rolled sanitary thin paper P gets caught on multiple protrusions 12 provided on the inner surface of the container body 1, making it easy for the sanitary thin paper P to instantly adhere to the inner surface of the container body 1. For example, if the tip of the protrusion 12 is sharp, the sanitary thin paper P will be more easily caught by the protrusion 12, and the sanitary thin paper P will be more easily attached to the inner surface of the container body 1.

[0019] (Lid) The lid 2 is composed of a lid main body 21 and a small lid 22, as shown in FIGS.

[0020] The lid body main body 21 is formed, for example, from PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), ABS resin, etc., has a cylindrical shape with an open bottom, and is provided with a top surface portion 21a, a side surface portion 21b, a recess 21c formed in a concave shape facing downward on the inner periphery side of the top surface portion 21a when viewed in a plan view, a hole portion 21d, and a main body side wall portion 21e erected in a cylindrical shape within the recess 21c to surround the hole portion 21d. The lid body 21 is formed in a cylindrical shape having a circular shape with a diameter of 50 mm to 200 mm in plan view, a Z-axis direction (height) of 15 mm to 50 mm, and a thickness of each face of 0.5 mm to 10 mm.

[0021] Further, a female screw portion 211 that screws into the male screw portion 11 of the container body 1 is provided on the inner peripheral surface of the lower end portion of the side portion 21b. As a result, as shown in FIG. 2, the container body 1 and the lid body 2 have a detachable connection structure via the male screw portion 11 and the female screw portion 211, and the lid body 2 can be removed from the container body 1.

[0022] (Concave part of the lid) The recess 21c is formed so that its shape in plan view is approximately the same as that of the small lid 22 when closed, and so that the small lid 22 can be fitted in. The recess 21c is also formed so that its front end is larger than the small lid 22 in plan view, and so that a small gap remains even when the small lid 22 is fitted in. This makes it possible to hook a finger on the small lid 22 by utilizing the gap.

[0023] (hole) Hole portion 21d is a hole that is formed in a circular shape in a plan view at approximately the center of the lid body main body 21 in a plan view and leads to the inside of the sanitary tissue paper storage container 100.In a plan view, it is formed to be slightly smaller than the removal portion 3, and the removal portion 3 is fixed to hole portion 21d as described below.

[0024] (Main body side wall) The main body side wall 21e is formed in the recess 21c in a cylindrical shape extending upward so as to surround the periphery of the hole 21d. The main body side wall 21e is formed so that its outer diameter is the same as or slightly smaller than the inner diameter of the small lid side wall 22a of the small lid 22.

[0025] (small lid) The small lid 22 is formed from, for example, PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), ABS resin, etc., and has an end connected to the lid body 21 and a small lid side wall 22a protruding from the lower surface when closed. The small lid 22 is formed so that the shape of the small lid 22 in a plan view when closed substantially matches the shape of the recess 21c, and can be fitted into the recess 21c when closed.

[0026] (Small lid side wall) The small lid side wall 22a is formed in a cylindrical shape that extends downward when the small lid 22 is closed. The small lid side wall 22a is formed so that the inner diameter is the same as or slightly larger than the outer diameter of the main body side wall 21e. The small lid side wall 22a is adapted to come into contact with the upper surface of the recess 21c when the small lid 22 is closed. This allows the small lid side wall 22a and the main body side wall 21e to fit together when the small lid 22 is closed, thereby maintaining the airtightness of the space surrounded by the small lid side wall 22a and the main body side wall 21e, and thus the inside of the sanitary tissue paper storage container 100 connected to the space via the hole 21d.

[0027] In this embodiment, the airtightness inside the sanitary tissue paper storage container 100 is maintained by fitting the main body side wall portion 21e and the small lid side wall portion 22a together, but it is also possible to use a configuration different from the above as long as the airtightness inside the sanitary tissue paper storage container 100 can be maintained. In addition, if the sanitary tissue paper to be stored is not soaked in a liquid medicine or the like and there is no need to prevent it from drying out, the container may be configured without any airtight means.

[0028] (Ejecting part) The removal portion 3 is, for example, as shown in FIG. 4, an elastically deformable member formed in a substantially cylindrical shape that is circular in a plan view, and can be formed by, for example, injection molding. The removal portion 3 is a member for removing the sanitary thin paper P stored inside the container body 1. Specifically, the removal section 3 has a recess 31 having an inner bottom surface formed in the center when viewed from above, a constricted portion 32 formed on the side, and a removal hole 33 formed approximately in the center of the recess 31. The removal portion 3 has a circular shape that is slightly larger than the hole portion 21d and is equal to or greater than one-tenth and equal to or less than one-third the diameter of the lid body 21 in plan view.

[0029] (Recessed portion of removal section) The recess 31 is formed, except for the peripheral portion, in the upper surface of the extraction portion 3 so as to be concave downward in a circular shape when viewed from above. The depth of this recess 31 (depth in the Z-axis direction) is formed to be 2 mm to 10 mm. Moreover, the recess 31 is formed so that its inner bottom surface is flat.

[0030] (Constricted part) The constricted portion 32 is formed in a radially recessed groove shape so as to go around the circumferential direction of the approximately vertical center of the side surface of the extraction portion 3 and to a depth, in plan view, of 1 / 20 to 1 / 10 of the diameter of the extraction portion 3. The dimension of this constricted portion 32 in the Z-axis direction is formed to be 0.5 mm to 3.0 mm. As described above, the removal portion 3 is formed to be slightly larger than the hole portion 21d in a planar view. Therefore, by fitting the edge of the hole portion 21d into this narrowed portion 32, the removal portion 3 can be fixed to the lid body 21.

[0031] (Ejection hole) The removal hole 33 is a hole for removing the sanitary thin paper P stored inside the container body 1. The take-out hole 33 holds the sanitary thin paper P inserted from the underside in a state in which the end portion on the tip side thereof protrudes from the upper surface of the take-out part 3 (the inner bottom surface of the recess 31). When the leading end of the sanitary thin paper P protrudes from the upper surface of the take-out section 3, the protruding amount is 10 mm to 30 mm, and preferably 13 mm to 20 mm. This protruding amount makes it easy for a typical user to pick it up with their fingers and to easily perform the take-out operation.

[0032] The extraction hole 33 typically has a small hole 33a that is substantially circular in plan view, and a plurality of slits 33b that are formed radially from the small hole 33a. Note that the term "substantially circular" as used herein includes not only a perfect circle, but also an ellipse, a distorted circle, and the like. In this embodiment, for example, four slits 33b are provided around the small hole 33a as shown in Fig. 4. The slits 33b are provided at 90° intervals around the small hole 33a. The diameter of the small holes 33a is 1.0 mm to 5.0 mm, preferably 2.0 mm to 4.0 mm. If the diameter of the small holes 33a is too large, the next sheet cannot be held and will fall, whereas if the diameter is too small, a lot of force is required to remove the sheet.

[0033] This removal hole 33 applies resistance to the pulled-out sanitary thin paper P, allowing the sanitary thin paper P to be used to be cut off along the perforation P1 while keeping the end of the subsequent sanitary thin paper P in a position where an appropriate amount of the end protrudes from the removal hole 33. In this way, with the removal hole 33 consisting of a small hole 33a and multiple slits 33b, it is possible to achieve both reliable retention of the sanitary thin paper P in the removal hole 33 and ease of pulling out the sanitary thin paper P held in the removal hole 33. 4 illustrates the case where four slits 33b are formed, but the shape of the extraction hole 33 is not limited to this, and any number of slits 33b may be formed as long as the above function can be performed. In other words, the extraction hole 33 may be a combination of a circular or elliptical small hole 33a and any number of slits 33b.

[0034] <Operation of the embodiment> In the above-mentioned sanitary tissue paper storage container 100, the roll-shaped sanitary tissue paper P stored in the sanitary tissue paper storage container 100 (container body 1) comes into contact with the inner surface of the container body 1, causing the roll-shaped sanitary tissue paper P to get caught on multiple protrusions 12 provided on the inner surface of the container body 1, making it easy for the posture and orientation of the roll-shaped sanitary tissue paper P within the container body 1 to change. For example, when the sanitary tissue paper storage container 100 is shipped from a factory to a logistics center, or when the sanitary tissue paper storage container 100 is brought from the logistics center to a store, the sanitary tissue paper storage container 100 is shaken during transport, and when the roll of sanitary tissue paper P inside the sanitary tissue paper storage container 100 comes into contact with the inner surface of the container body 1, it is instantly caught by the multiple protrusions 12 and attached thereto, causing the posture and orientation of the roll of sanitary tissue paper P to easily change. Furthermore, when the posture and orientation of the rolled sanitary tissue paper P changes in various ways inside the sanitary tissue paper storage container 100, the rolled sanitary tissue paper P is subjected to impacts and vibrations, causing the bundle of sanitary tissue paper P wound in a roll to unravel. In this way, by unwinding the bundle of sanitary thin paper P wound in a roll, the roll of sanitary thin paper P loosens, making it easier to pull out the sanitary thin paper P from the center side of the roll.

[0035] In addition, when the roll of sanitary thin paper P has been used up and the sanitary thin paper storage container 100 is empty, before storing refillable sanitary thin paper P in the sanitary thin paper storage container 100 and starting to use it, shake and rock the sanitary thin paper storage container 100 multiple times (for example, several dozen to several tens of times) so that the roll of sanitary thin paper P in the sanitary thin paper storage container 100 comes into contact with the inner surface of the container body 1. This will unravel the bundle of sanitary thin paper P wound into a roll and loosen the winding of the roll of sanitary thin paper P, making it easier to pull out the sanitary thin paper P from the center of the roll. In addition, if a user finds it difficult to pull out the sanitary thin paper P from the sanitary thin paper storage container 100, shaking the sanitary thin paper storage container 100 multiple times will loosen the roll of sanitary thin paper P, making it easier to pull out the sanitary thin paper P from the sanitary thin paper storage container 100.

[0036] <Effects of the embodiment> According to this embodiment, in a sanitary tissue paper storage container 100 comprising a container body 1 having an opening 1a on the top surface and storing a roll of sanitary tissue P inside through the opening 1a, and a lid body 2 which is attached detachably so as to cover the opening 1a of the container body 1 and has a removal section 3 for removing the sanitary tissue paper P stored inside the container body 1, the sanitary tissue paper P stored in the container body 1 is pulled out from the center side of the roll and removed through the removal section 3, and a plurality of protrusions 12 are provided on the inner surface of the container body 1, and when the sanitary tissue paper P stored in the container body 1 comes into contact with the inner surface of the container body 1, the protrusions 12 instantly adhere the sanitary tissue paper P to the inner surface.

[0037] The sanitary tissue paper storage container 100 of this embodiment has this type of configuration, and when the roll of sanitary tissue paper P is momentarily attached to the inner surface of the sanitary tissue paper storage container 100, for example, and the posture and orientation of the roll of sanitary tissue paper P changes variously inside the sanitary tissue paper storage container 100, the roll of sanitary tissue paper P is subjected to impact or vibration, causing the bundle of sanitary tissue paper P wound in a roll to unravel and become loose. Furthermore, by unwinding the bundle of sanitary tissue paper P wound in a roll, it becomes easier to pull out the sanitary tissue paper P from the center side of the roll, making it possible to conveniently pull out the sanitary tissue paper P from the sanitary tissue paper storage container 100 and use it.

[0038] <Modification> The present invention is not limited to the above-described embodiment. For example, as shown in Figure 5, the tip of the protrusion 12 provided on the inner surface of the sanitary tissue paper storage container 100 (container body 1) may have a shape that protrudes toward the opening 1a of the container body 1. The protrusion 12 may be a generally conical protrusion or a generally triangular plate-like protrusion. Even in a sanitary tissue paper storage container 100 having multiple protrusions 12 on its inner surface, the roll of sanitary tissue paper P stored inside can be easily loosened, and the sanitary tissue paper P can be conveniently pulled out of the sanitary tissue paper storage container 100 and used. In particular, if the tip of the protrusion 12 faces diagonally upwards, the roll of sanitary tissue paper P may get caught on the protrusion 12 and become momentarily suspended, at which point the center side of the roll lowers, making it easier to unwind, and the sanitary tissue paper P can be conveniently pulled out of the sanitary tissue paper storage container 100. Furthermore, if the protrusion 12 has a tip pointing diagonally upwards, even if the roll of sanitary tissue paper P gets caught on the protrusion 12 and becomes suspended in mid-air, it will come off when the sanitary tissue paper P is pulled out of the sanitary tissue paper storage container 100 and return to its specified storage state, so it can continue to be used conveniently. The tip of the projection 12 may face upward from the horizontal direction, but it is preferable that the tip faces obliquely upward at an angle of 20 to 70° from the horizontal direction, for example.

[0039] As shown in FIG. 6, the protrusion 12 provided on the inner surface of the sanitary tissue paper storage container 100 (container body 1) may have a hook shape with a curved tip. Even in a sanitary tissue paper storage container 100 having multiple protrusions 12 on its inner surface, the roll of sanitary tissue paper P stored inside can be easily loosened, and the sanitary tissue paper P can be conveniently pulled out of the sanitary tissue paper storage container 100 and used. In particular, if the protrusion 12 is hook-shaped with a curved tip, the roll of sanitary tissue paper P may get caught on the protrusion 12 and become momentarily suspended, at which point the center of the roll drops, making it easier to unwind, and the sanitary tissue paper P can be conveniently pulled out of the sanitary tissue paper storage container 100.

[0040] Also, as shown in FIG. 7, the protrusions 12 provided on the inner surface of the sanitary tissue paper storage container 100 (container body 1) may be made of a relatively soft resin material, for example, an elastic material such as silicone. The protrusion 12 here has a spherical protuberance. The protrusions 12 can be provided by, for example, two-color molding. If the multiple protrusions 12 provided on the inner surface of the container body 1 are formed from an elastic resin material, when the roll of sanitary tissue paper P stored in the sanitary tissue paper storage container 100 (container body 1) comes into contact with the inner surface of the container body 1, a relatively strong frictional force is generated, causing the bundle of sanitary tissue paper P wound in a roll to unravel. Even in a sanitary tissue paper storage container 100 having multiple protrusions 12 on its inner surface, the roll of sanitary tissue paper P stored inside can be easily loosened, and the sanitary tissue paper P can be conveniently pulled out of the sanitary tissue paper storage container 100 and used.

[0041] As described above, with the sanitary tissue paper storage container 100 of this embodiment, the roll-shaped sanitary tissue paper P stored inside can be conveniently pulled out and used.

[0042] The application of the present invention is not limited to the above-described embodiment, and can be modified as appropriate without departing from the spirit of the present invention. [Explanation of symbols]
