DETAILED DESCRIPTION OF THE INVENTION

[0012] Specific aspects of a sanitary tissue paper storage container according to an embodiment of the present invention will be described in detail below with reference to Figures 1 to 10. However, the technical scope of the present invention is not limited to the illustrated examples. 1 to 10, the following description will define the X-axis, Y-axis, and Z-axis, as well as the front-to-back, left-to-right, and up-to-down directions. That is, in the sanitary tissue paper storage container 100, the side from which sheets are removed 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 back, 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. 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.

[0013] [Overall configuration] As shown in Figure 1, the sanitary tissue paper storage container 100 is composed of a container body 1 that stores sanitary tissue paper P inside, a lid body 2 that can be removably attached to the container body 1 to cover the opening, and a removal section 3 that can be attached to the lid body 2. The lid body 2 is configured to be detachable from the container body 1, so that the sanitary tissue paper P can be stored in or removed from the container body 1 with the lid body 2 removed from the container body 1.

[0014] [Hygienic tissue paper] The sanitary thin paper P is, for example, a roll of wet wipes or wet tissues, and is stored in the container body 1 in a rolled state around an axis along the Z-axis (height direction). The sanitary thin paper P is also perforated at regular intervals along its length, and the user can use the sheets that have been cut off along the perforations. In the following, a case where the sheet is pulled out from the center side of the roll will be described, but the present invention is not limited to this and the sheet may be pulled out from the outside.

[0015] [Container body] As shown in Figures 1 to 3, the container body 1 is a container for storing sanitary tissue paper P, and is formed in a cylindrical shape with a bottom, with an opening on the top surface. Also, as shown in Figure 2, a male screw portion 11 is provided along the circumferential direction on the outer surface of the upper end of the side. Also, as shown in Figure 3, a rotation mechanism 12 is provided on the inner surface of the bottom surface.

[0016] The container body 1 is integrally formed by injection molding, two-color molding, blow molding, or the like using, for example, PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), ABS resin, or the like. The container body 1 is preferably circular in plan view with a diameter of 60 mm to 200 mm, more preferably 65 mm to 110 mm, and is formed into a cylindrical shape with a diameter in the Z-axis direction (height direction) of preferably 175 mm to 200 mm, more preferably 175 mm to 185 mm, and a thickness on each side of preferably 0.05 mm to 10.00 mm, more preferably 0.10 mm to 5.00 mm.

[0017] (Rotation mechanism) As shown in FIG. 3, the rotation mechanism 12 is provided on the bottom surface of the container body 1, and is configured to be rotatable on the bottom surface of the container body 1 with the Z-axis direction as the rotation axis, like a so-called turntable. Specifically, the rotation mechanism 12 comprises a loading plate 121 on which the rolled sanitary tissue paper P is placed, and a rotating part 122 provided on the underside of the loading plate 121 and rotating around an axis of rotation perpendicular to the Z-axis direction. The rotation mechanism 12 is not powered and is configured to be rotatable by external force when the sanitary tissue paper P is placed on it.

[0018] (Placement plate) The mounting plate 121 is a flat plate that is approximately parallel to the XY plane, and is, for example, approximately circular with the same center as the bottom surface of the container body 1, and is made of the same resin as the container body 1. The size of the loading plate 121 is not limited as long as it can stably support one end of the rolled sanitary tissue paper P stored in the container body 1, and can be determined according to the size of the container body 1 and the sanitary tissue paper P.

[0019] (rotating part) The rotating part 122 is configured to have, for example, casters with wheels, be fixed to the underside of the loading plate 121, and rotate on the bottom surface of the container body 1 with a rotation axis perpendicular to the Z-axis direction as the sheet is removed from the removal hole 33, and to rotate the loading plate 121 with the Z-axis direction as the rotation axis.

[0020] The rotating part 122 is not limited to a caster, and for example, a bearing can be used. With this configuration, even if the sanitary tissue paper storage container 100 is accidentally tipped over, it becomes easy to re-place the sanitary tissue paper P on the rotating mechanism 12. The rotating part 122 may have any known configuration as long as it can rotate the mounting plate 121 around the Z axis as the rotation axis.

[0021] (lubricant) A lubricant may be applied to facilitate rotation of the rotating part 122. Examples of lubricants that can be used include liquid paraffin, silicone, grease, and oil.

[0022] [Lid] As shown in FIGS. 1 and 2, the lid 2 is made up of a lid main body 21 and a small lid 22.

[0023] (lid body) The lid body main body 21 is integrally formed by injection molding, two-color molding, blow molding, etc. using, for example, PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), ABS resin, etc., and has a cylindrical shape with an open bottom surface, 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 plan, a hole portion 21d, and a main body side wall portion 21e that is erected in a cylindrical shape within the recess 21c to surround the hole portion 21d. The lid body 21 is preferably circular in plan view with a diameter of 60 mm to 200 mm, more preferably 65 mm to 110 mm, and is formed into a cylindrical shape with a diameter in the Z-axis direction (height direction) of preferably 15 mm to 50 mm, more preferably 33 mm to 45 mm, and a thickness on each side of preferably 0.05 mm to 10.00 mm, more preferably 0.10 mm to 5.00 mm.

[0024] (Top part) As shown in FIGS. 1 and 2, the top surface 21a is the outer peripheral portion of the top surface of the cylindrically formed lid body 21, excluding the recess 21c.

[0025] (side part) As shown in FIGS. 1 and 2, the side surface portion 21b is a portion that forms the side surface of the lid body 21 that is formed in a cylindrical shape. A female screw portion 211 that screws into the male screw portion 11 of the container body 1 is provided on the inner surface of the lower end of the side surface portion 21b. As a result, as shown in Figure 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, making it possible to remove the lid body 2 from the container body 1.

[0026] (recess) The recess 21c is formed so that its shape in a plan view roughly matches that of the small lid 22 when closed, allowing the small lid 22 to be fitted in. The front end of the recess 21c is larger than the small lid 22 in a plan view, and a small gap remains even when the small lid 22 is fitted in. This makes it possible to use the gap to hook a finger on the small lid 22.

[0027] (hole) Hole portion 21d is a hole that is formed in a circular shape in a plan view at approximately the center of lid body main body 21 in a plan view and leads to the inside of container main body 1.In a plan view, it is formed to be slightly smaller than removal portion 3, and removal portion 3 is fixed to hole portion 21d as described below.

[0028] (Main body side wall) The main body side wall 21e is formed in the recess 21c so as to surround the periphery of the hole 21d and extend upward in a cylindrical shape. The main body side wall 21e is formed so that the outer diameter thereof is the same as or slightly smaller than the inner diameter of the small cover side wall 22a formed on the small cover 22.

[0029] (small lid) The small lid 22 is integrally formed by injection molding, two-color molding, blow molding, or the like using, for example, PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), ABS resin, or the like, and has a small lid side wall 22a that protrudes from the bottom surface when closed. The shape of the small lid 22 in a plan view when closed substantially matches that of the recess 21c, and is formed so that it can be fitted into the recess 21c when closed.

[0030] (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 its 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 configured 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, maintaining airtightness of the space surrounded by the small lid side wall 22a and the main body side wall 21e, and ultimately the interior of the container body 1 that is connected to this space via the hole 21d.

[0031] In this embodiment, the container body 1 is configured to maintain airtightness inside by fitting the main body side wall portion 21e and the small lid side wall portion 22a together, but a different configuration from the above is also possible as long as the container body 1 can maintain airtightness inside.

[0032] [Ejecting section] 4 and 5, the removal portion 3 is an elastically deformable member formed in a generally cylindrical shape that is circular in plan view. Fig. 5 is a bottom view of the removal portion 3, showing the removal portion 3 of Fig. 4 as viewed from below. Specifically, the removal section 3 comprises a recess 31 having an inner bottom surface 3a formed in the center when viewed from above, a constricted portion 32 formed on the side, a removal hole 33 formed approximately in the center when viewed from above of the recess 31 (inner bottom surface 3a), and a chamfered portion 34 formed by chamfering the peripheral portion of the removal hole 33 on the lower surface 3b. The thickness R1 (see FIG. 6) of the extraction portion 3 in the Z-axis direction below the constricted portion 32 (the dimension between the inner bottom surface 3a and the lower surface 3b) is set to 1.0 mm to 5.0 mm, preferably 1.5 mm to 3.0 mm.

[0033] (recess) The recess 31 is formed on the upper surface of the extraction portion 3 so as to be concave downward in a circular shape in a plan view, leaving a peripheral edge portion, and the recess 31 is formed so that its inner bottom surface 3a is flat. The recess 31 is formed so that its inner bottom surface 3a is flat.

[0034] (Constricted part) The constricted portion 32 is formed as a radially recessed groove having a depth in plan view of 1 / 20 to 1 / 10 of the diameter of the removal portion 3, running around the circumferential direction approximately in the center in the up-down direction of the side surface of the removal portion 3. As described above, the removal portion 3 is formed to be slightly larger than the hole 21d in plan view, and therefore, by fitting the edge of the hole 21d into the constricted portion 32, the removal portion 3 can be fixed to the lid body 21.

[0035] (Ejection hole) The take-out hole 33 is a hole for taking out the sheet of sanitary thin paper P stored inside the container body 1. The take-out hole 33 holds the sheet inserted from the lower surface 3b side in a state in which the tip of the sheet protrudes from the upper surface of the take-out portion 3 (the inner bottom surface 3a of the recess 31). When the leading edge of the sheet protrudes from the top surface of the take-out section 3, the protruding amount is 5 mm to 39 mm, preferably 13 mm to 20 mm. A protruding amount of 5 mm or more makes it easy for a typical user to pick up the sheet with their fingers and facilitates the removal operation. Furthermore, a protruding amount of 39 mm or less prevents the end of the sheet from protruding from the lid 2 when the lid 2 is closed.

[0036] The extraction hole 33 is formed by a cutout portion 330 in the approximate center of the extraction portion 3 in a plan view, where two straight lines intersect in a cross shape. As shown in FIG. 5, the notch 330 has, for example, four straight portions 331, a first circular portion 332 provided at the intersection of one end of the straight portions 331, and a second circular portion 333 provided at the other end of the straight portions 331 and having a smaller diameter than the first circular portion 332. The total length of cutout 330 is set to 5 mm to 30 mm, preferably 10 mm to 15 mm, and is set to, for example, about 15 mm, which is greater than the width of a typical user's index finger. By forming cutout 330 as a cross-shaped cutout in this way, it is possible to further increase the reliability with which cutout 330 holds the sheet. The diameter of the first circular portion 332 is formed to be 2.5 mm to 4.0 mm, and by providing the first circular portion in this manner, it is possible to lengthen the gripping distance of the sheet that is held by the take-out portion 3 after the sheet has been taken out. Also, by providing the second circular portion, it is possible to take out the sheet with less force.

[0037] 5 illustrates and describes the case where the extraction hole 33 is formed in a cross shape, but the shape of the extraction hole 33 is not limited to this and any shape can be selected as long as it can fulfill the above function. That is, the extraction hole 33 may be formed by three or more linear cuts forming a radial pattern. Furthermore, the extraction hole 33 may be formed by a single linear cut, or may be in a circular, elliptical, or approximately star-shaped shape.

[0038] (chamfered part) As shown in FIGS. 5 and 6, the chamfered portion 34 is a region where the corner formed by the lower surface 3b of the extraction portion 3 and the hole wall 33a of the extraction hole 33 is chamfered. Specifically, the chamfered portion 34 is a flat chamfered portion formed by chamfering the edge of the hole wall 33a of the extraction hole 33 on the lower surface 3b of the extraction section 3 with an inclined plane, thereby giving the extraction hole 33 a shape in which the opening area on its lower end side is larger than the opening area on its upper end side. As shown in FIG. 7, the size of the chamfered portion 34 is preferably set so that the length L1 from the hole wall 33a of the extraction hole 33 in the XY plane direction of the extraction hole 33 is within a range of 0.5 mm to 1.0 mm, and the length L2 from the lower end of the extraction hole 33 in the Z-axis direction is within a range of 0.5 mm to 1.0 mm.

[0039] Here, the case where the chamfered portion 34 is formed by chamfering a flat surface has been illustrated and explained, but the chamfered portion 34 may also be a curved chamfered portion in which the corner formed by the lower surface 3b of the extraction portion 3 and the hole wall 33a of the extraction hole 33 is chamfered to form a convex curved surface, as shown in Figure 8.

[0040] The removal portion 3 described above must be insertable into the hole 21d and must not come off the lid body 21 when the sanitary tissue paper storage container 100 is in use. Furthermore, since it is necessary to be able to push a sheet into the removal hole 33 with a finger, it must be formed using a material with a certain degree of elasticity. Specifically, a hardness of 50 to 70 is desirable, and elastomers such as styrene-butadiene, polyester, polyethylene, and urethane can be used, and the material is formed by injection molding. The above hardness is measured according to JIS K 6253 (Type A durometer).

[0041] Furthermore, when coloring the take-out part 3, for example, a resin such as PE (polyethylene) mixed with a desired pigment is mixed with the elastomer (pigment adding process). At this time, by changing the mixing ratio of the elastomer and the PE resin, the sheet take-out performance of the take-out part 3 can be adjusted. Here, the resin to be mixed with the elastomer may be any resin as long as it has a higher hardness than the elastomer.

[0042] Furthermore, in the take-out section 3, when the force required to pull out the sheet is measured five times using a digital force gauge (manufactured by IMADA: model number DS2-200N) and the average value is defined as the resistance value, the resistance value is preferably in the range of 5N to 12N, and more preferably 6N to 10N. Furthermore, when pulling out a roll of sanitary tissue paper P (for example, 80 sheets connected together with 79 perforations), the acceptable range for the number of times (number of consecutive times) that the perforations do not break and subsequent sheets continue to come out is within 10 times, and preferably within 7 times.

[0043] [Effects of the embodiment] The main effects that can be obtained by this embodiment will be described below.

[0044] As shown in Figure 10, in the case of a conventional sanitary tissue paper storage container 200, when a sheet of rolled sanitary tissue paper P is pulled out from its center, the sheet is pulled out in a rotating manner, which inevitably causes the sheet to twist in a certain direction (in Figure 10, the counterclockwise direction with the Z-axis direction as the axis of rotation). However, as shown in Figure 9, the sanitary tissue paper storage container 100 of this embodiment is equipped with a rotation mechanism 12 on the bottom surface that can rotate around the Z-axis direction as a rotation axis due to an external force, so even if the sheet is pulled out from the center of the roll while twisting, when the sheet is pulled out, the loading plate 121 and the sanitary tissue paper P will rotate in the same direction as the twist of the sheet (counterclockwise with the Z-axis direction as the rotation axis).

[0045] This eliminates twists when the sheet is pulled out, and the removed sheet is less likely to become twisted, eliminating the need to unfold the sheet before use, and also preventing the sheet from curling up during use, as the removed sheet is less likely to crease or become curled. Furthermore, if the sheet passes through the removal hole 33 in a twisted state, it may get caught in the removal hole 33, making it difficult to remove the next sheet; however, the sanitary tissue paper storage container 100 of this embodiment can reduce this risk.

[0046] [Variations] Although the present invention has been specifically described above based on the embodiments, the present invention is not limited to the above embodiments and can be modified within the scope of the invention. For example, if the rotating parts 122 are casters, the number of rotating parts 122 is not limited to four as shown in Figure 3, but considering the stability of the support of the sanitary tissue paper P by the loading plate 121, it is preferable that at least three or more are provided at approximately equal intervals.

[0047] Furthermore, the shape of the sanitary tissue paper storage container 100 does not necessarily have to be cylindrical, and may be formed into a prismatic shape that is pentagonal, hexagonal, or the like in a plan view, for example. Moreover, the removal part 3 may be detachable from the lid 2 or may be fixed thereto. [Explanation of symbols]
