Description

[Technical field]

[0001] The present invention relates to a sanitary sheet storage container and a method for manufacturing a sanitary sheet storage container. [Background technology]

[0002] Conventionally, a sanitary sheet storage container that stores sanitary sheets impregnated with a chemical solution for wiping house floors, toilets, the human body, etc. has been known that stores a roll of sanitary sheets inside a container body with an opening. Such a sanitary sheet storage container is known to have a configuration in which a hole provided in a lid attached to cover the opening of the container body is provided with a removal part having a removal hole, and the removal hole applies resistance to the sanitary sheet with perforations to separate it (for example, see Patent Documents 1, 2, and 3). The sanitary sheets stored in such sanitary sheet storage containers are impregnated with a chemical solution during the manufacturing process. Specifically, after a roll of sanitary sheets is placed in the sanitary sheet storage container, a chemical solution is applied to the sanitary sheets from a nozzle above the container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Specific aspects of a sanitary sheet 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. In the following description, the X-axis, Y-axis, and Z-axis as well as the front-rear, left-right, and up-down directions are defined as shown in Figures 1 to 10. That is, in the sanitary sheet storage container 100, the side from which the sanitary sheet P is taken out is referred to as the top, the opposite side is referred to as the bottom, the near side in a plan view of the sanitary sheet storage container 100 is referred to as the front, the opposite side is referred to as the rear, the right hand side when the front face of the container is viewed from the front is referred to as the right, and the left hand side when the front face of the container is viewed from the front is referred to as the left, and the axis along the front-rear direction is referred to as the X-axis, the axis along the left-right direction is referred to as the Y-axis, and the axis along the up-down direction is referred to as the Z-axis.

[0011] [Overall configuration] As shown in FIG. 1, the sanitary sheet storage container 100 comprises a container body 1 for storing sanitary sheets P therein, a lid body 2 which is removably attached to the container body 1 so as to cover the opening, and a removal section 3 which is attached to the lid body 2. The lid body 2 is configured so as to be freely attached and detached to the container body 1, so that with the lid body 2 removed from the container body 1, the sanitary sheet P can be stored inside the container body 1 or removed.

[0012] [Hygiene sheets] The sanitary sheet P is a roll-shaped sanitary sheet impregnated with a medicinal liquid, for example, a roll of wet wipes or other rolled paper, and is stored in the container body 1 in a rolled state around an axis along the Z-axis direction (height direction). The sanitary sheet P is perforated at regular intervals along its length, and the user is allowed to use the sheet that has been cut off along the perforations. The sheet is pulled out from the center side of the roll. The roll-shaped sanitary sheet also has a space S at its center that communicates from the top end to the bottom end.

[0013] [Container body] As shown in Figures 1 to 3, the container body 1 is a container for storing sanitary sheets P, and is formed in a cylindrical shape with a bottom, with an opening provided on the top surface. Also, a male screw portion 11 is provided along the circumferential direction on the outer surface of the upper end portion of the side surface, as shown in Figure 2. Also, a protrusion 12 is provided on the inner bottom surface, as shown in Figure 3.

[0014] 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 with a diameter of 60 mm to 200 mm, more preferably 65 mm to 110 mm, when viewed in a plane, and is formed into a cylindrical shape with a diameter of preferably 175 mm to 200 mm, more preferably 175 mm to 185 mm in the Z-axis direction (height direction), and the thickness of each side is preferably 0.05 mm to 10.00 mm, more preferably 0.10 mm to 5.00 mm.

[0015] (protrusion) As shown in Fig. 3, the protrusion 12 is provided at the center of the inner bottom surface of the container body 1 and has a cylindrical shape. Its diameter is larger than the diameter of the space S of an unused roll of sanitary sheet P. Therefore, an unused roll of sanitary sheet P rests on the protrusion 12, and the upper surface of the protrusion 12 functions as a support portion that supports the roll of sanitary sheet P. The height in the Z-axis direction may be any height that allows the roll of sanitary sheet P to fit into the sanitary sheet storage container 100 when the roll of sanitary sheet P rests on the protrusion 12.

[0016] [Lid] The lid 2 is composed of a lid main body 21 and a small lid 22, as shown in FIGS.

[0017] (Lid body) The lid body main body 21 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, 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 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 preferably circular with a diameter of 60 mm to 200 mm, more preferably 65 mm to 110 mm, in a plan view, and is formed into a cylindrical shape with a diameter of preferably 15 mm to 50 mm, more preferably 33 mm to 45 mm in the Z-axis direction (height direction), and a thickness of each face of preferably 0.05 mm to 10.00 mm, more preferably 0.10 mm to 5.00 mm.

[0018] (Top part) As shown in Figs. 1 and 2, the top surface 21a is a portion of the upper surface of the lid body 21 formed in a cylindrical shape, on the outer circumferential side other than the recessed portion 21c.

[0019] (side part) As shown in Figs. 1 and 2, the side surface portion 21b is a portion that forms a 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 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.

[0020] (recess) 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.

[0021] (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 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.

[0022] (Main body side wall) The main body side wall 21e is formed in the recess 21c so as to surround the hole 21d and extend upward in a cylindrical shape. The main body side wall 21e is formed so as to have an outer diameter equal to or slightly smaller than the inner diameter of the small lid side wall 22a formed in the small lid 22.

[0023] (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 protruding from the lower surface when closed. The small lid 22 is formed so that its shape in a plan view when closed substantially matches that of the recess 21c, and can be fitted into the recess 21c when closed.

[0024] (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 container body 1 connected to the space via the hole 21d.

[0025] In this embodiment, the container body 1 is configured to maintain airtightness inside by engaging the main body side wall portion 21e with the small lid side wall portion 22a, but a configuration different from the above is also possible as long as the container body 1 can maintain airtightness inside.

[0026] [Ejecting section] The extraction portion 3 is an elastically deformable member formed in a generally cylindrical shape that is circular in a plan view. Specifically, the removal section 3 has 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, and a removal hole 33 formed in approximately the center of the recess 31 (inner bottom surface 3a) when viewed from above. The thickness R1 in the Z-axis direction below the constricted portion 32 in the extraction portion 3 (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.

[0027] (recess) The recess 31 is formed on the upper surface of the extraction portion 3, and is formed downward in a circular shape in a plan view, except for the peripheral portion. 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.

[0028] (Constricted part) The constricted portion 32 is formed in a radially recessed groove shape so as to go around the circumferential direction at approximately the center in the up-down direction of the side surface of the removal portion 3 and to a depth of 1 / 20 to 1 / 10 of the diameter of the removal portion 3 in a plan view. Since the removal portion 3 is formed slightly larger than the hole portion 21d in a plan view as described above, it is possible to fix the removal portion 3 to the lid body 21 by fitting the edge of the hole portion 21d into the constricted portion 32.

[0029] (Ejection hole) The removal hole 33 is a hole for removing the sanitary sheet 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 end of the sheet protrudes from the upper surface of the take-out section 3, the protruding amount is 5 mm to 39 mm, preferably 13 mm to 20 mm. When the protruding amount is 5 mm or more, it is easy for a typical user to pick up the sheet with their fingers, and the sheet can be easily taken out. When the protruding amount is 39 mm or less, the end of the sheet does not protrude from the cover 2 when the cover 2 is closed.

[0030] Further, the extraction hole 33 is formed by a cutout portion in which two straight lines intersect in a cross shape at approximately the center of the extraction portion 3 in a plan view.

[0031] The above-mentioned removal part 3 must be insertable into the hole 21d and not come off from the lid body 21 when the sanitary sheet storage container 100 is in use, and must be formed using a material with a certain degree of elasticity since it is necessary to be able to push the sheet into the removal hole 33 with a finger. Specifically, the hardness is preferably 50 to 70, and specifically, for example, styrene-butadiene, polyester, polyethylene, urethane, or other elastomers can be used, and the material is formed by injection molding. The above hardness is measured according to JIS K 6253 (Type A durometer).

[0032] (Method of impregnating with chemicals) In the process of applying the chemical solution to the roll-shaped sanitary sheet P stored in the sanitary sheet storage container 100 according to this embodiment, for example, a nozzle-type spraying method using a nozzle-type spraying device is used, as shown in Fig. 4. In order to suitably spray the chemical solution onto the sanitary sheet P, the nozzle diameter, the number of nozzles, the nozzle arrangement pattern, the number of nozzles arranged, or the spray distance, spray pressure, spray angle, and the concentration and viscosity of the spray liquid can be appropriately selected and used.

[0033] (Chemical solution) In the present invention, the chemical liquid to be applied to the sanitary sheet P is preferably a water-based liquid, and examples thereof include fragrances, moistening agents, softeners, smoothing agents, and deodorants. The fragrance may be one or more types appropriately selected from natural fragrances such as herbal fragrance components such as menthol, mint, lavender, and rosemary, rose fragrance components, citrus fragrance components, and cypress fragrance components, and synthetic fragrances. As the wetting agent, one or more kinds can be appropriately selected and used from polyhydric alcohols such as glycerin, diglycerin, sorbitol, pentaerythritol, etc. As the softening agent, for example, one or several types may be appropriately selected and used from quaternary ammonium salts, amine salts, amines, surfactants, and the like. As the smoothing agent, one or more types may be appropriately selected and used from dimethylpolysiloxane, amino-modified silicone, polyether silicone oil, and the like. As the deodorant, one or more of various essential oils such as wood extracts from Japanese cypress, hinoki cypress, cedar, etc., and plant extracts from chamomile, bamboo grass, mugwort, tea, perilla, etc. can be appropriately selected and used.

[0034] [Effects of the invention] In the chemical solution application process using the nozzle-type spray method as shown in Figure 4, the chemical solution passes through the space S at the center of the roll-shaped sanitary sheet P (Figure 5: step 1). However, because of the protrusions 12, the roll-shaped sanitary sheet P is raised above the bottom surface, so any chemical solution that has not been fully impregnated accumulates at the bottom surface (Figure 5: step 2). This makes it possible to prevent impregnation from the bottom surface as well during the chemical solution application process, preventing over-impregnation of the center of the roll-shaped sanitary sheet P in the initial state and reducing the difference in the amount of chemical solution impregnated between the center and the outer circular portion.

[0035] Furthermore, as the roll-shaped sanitary sheet P is used from the center, the diameter of the space S of the roll-shaped sanitary sheet P becomes larger than the diameter of the upper surface of the protrusions 12. This causes the roll-shaped sanitary sheet P to fall to the bottom (FIG. 5: step 3). As a result, the roll-shaped sanitary sheet P comes into contact with the medicinal liquid that has accumulated on the bottom surface and becomes impregnated with it. As a result, the roll-shaped sanitary sheet P becomes impregnated during use, and the difference in the amount of medicinal liquid impregnated between the central part of the roll-shaped sanitary sheet P that has already been used and the outer circular part that will be used in the future can be reduced.

[0036] [Variations] Although the present invention has been specifically described based on the embodiment, the present invention is not limited to the above embodiment and can be modified without departing from the gist of the present invention.

[0037] For example, as shown in Figs. 6 and 7, the projections 12A and 12B may have a shape in which a plurality of pillars are stacked. As shown in Fig. 6, the protrusion 12A is a stepped column with a larger diameter on the bottom side, and as the roll of sanitary sheet P is used from the center, it drops in stages. In this case, the top surfaces of the first and second stages of the column function as supports. 7, when the diameters of the protrusions 12B from the top side are small, large, and small, and the diameter of the small pillar is smaller than the diameter of the space S of an unused roll of sanitary sheet P, the top surface of the second tier of pillars functions as a support. In this case, the first tier of pillars on the top side can prevent the roll of sanitary sheet P from moving in the horizontal direction, and the roll of sanitary sheet P can be stably supported.

[0038] For example, the protrusion 12C may be a cone, as shown in Fig. 8. In this case, as the rolled sanitary sheet P is used from the center, it gradually falls off. The side surface of the cone functions as a support portion.

[0039] For example, the protrusion 12D may be a frustum as shown in Fig. 9. In this case, as the rolled sanitary sheet P is used from the center, it gradually falls off. The side surface of the frustum functions as a support portion.

[0040] For example, as shown in Fig. 10, the protrusion 12E may have a shape in which a pyramid is placed on a pillar. Alternatively, a frustum may be placed on top of the pillar. In this case, the side surface of the pyramid or the frustum functions as a support portion.

[0041] Additionally, the protrusions 12 may be hollow or solid.

[0042] Furthermore, the projections 12 are not limited to the cylindrical, conical, and truncated conical shapes shown in Figs. 3 and 6 to 10, but may be prismatic, pyramidal, or truncated pyramidal shapes.

[0043] Furthermore, the shape of the sanitary sheet storage container 100 does not necessarily have to be cylindrical, and may be, for example, a prismatic shape that is pentagonal, hexagonal, or the like in a plan view. Moreover, the removal portion 3 may be detachable from the lid 2 or may be fixed thereto. [Explanation of symbols]
