DETAILED DESCRIPTION OF THE INVENTION

[0012] 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, although the embodiment described below has various limitations that are technically preferable for carrying out the present invention, the scope of the present invention is not limited to the following embodiment and illustrated examples.

[0013] In the following explanation, the X-axis, Y-axis, and Z-axis, as well as the front-to-back, left-to-right, and up-to-down directions, are defined as shown in each figure. That is, the side of the sanitary tissue paper storage container with the opening / closing lid is the "top," the opposite side is the "bottom," the side where the container body and the opening / closing lid are connected is the "rear," the opposite side is the "front," the right-hand side as viewed from the front is the "right," and the left-hand side 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. When the upper part of the container body rotates relative to the lower part of the container body, the direction in which the upper part of the container body faces changes. However, as shown in Figure 1, the direction will be explained based on the state in which the upper part of the container body and the lower part of the container body are combined and the storage space S is shielded.

[0014] [Configuration of the embodiment] (Overall composition) As shown in Figures 1 to 3, the sanitary tissue paper storage container 1 includes a container body 10 having an extraction section 113 with an extraction hole 113a for extracting the sanitary tissue paper P, an opening / closing lid 2 as a lid body that is rotatably supported on the rear side of the container body 10 so that it can be switched between a state in which the extraction section 113 is covered and a state in which the extraction section 113 is exposed, a biasing member 114 that is arranged between the lid body 2 and the container body 10 at the position on the side where the opening / closing lid 2 is supported on the container body 10 and biases the opening / closing lid 2 to rotate in a direction that exposes the extraction section 113, and a button section 3 that is provided on the front side of the container body 10 and serves as an operating section that switches between a closed state in which the opening / closing lid 2 covers the extraction section 113 and an open state in which the opening / closing lid 2 exposes the extraction section 113. Inside this sanitary tissue paper storage container 1, a storage space S is formed in which sanitary tissue paper P is stored.

[0015] (hygienic tissue paper) For example, a so-called pop-up sheet is used as the sanitary tissue paper P, in which wet wipes (wet tissues) are stacked in an alternating folded state so that when one wet wipe (wet tissue) is pulled out, the next wet wipe (wet tissue) is also pulled out. Alternatively, for example, a roll sheet can be used in which long wet wipes (wet tissues) are wound into a roll with perforations at regular intervals along the length and are to be torn along the perforations for use.

[0016] (Container body) As shown in Figures 1 to 4, the container body 10 is formed as a roughly rectangular parallelepiped that is longer in the left-to-right direction than in the front-to-back and up-to-down directions, and is divided into two parts, top and bottom, above the center in the up-to-down direction, and is formed into an upper container body 11 that forms the upper part of the container body 10 and a lower container body 12 that forms the lower part of the container body 10. The upper container body 11 and the lower container body 12 are connected by a connecting portion 13 at the rear surface of the container body 10 . The upper container body portion 11, the lower container body portion 12, and the connecting portion 13 are integrally formed by a method such as injection molding. The container body 10, which includes the container body upper part 11, the container body lower part 12, and the connecting part 13, is made of polypropylene, as will be described later.

[0017] As shown in Figures 1 to 4, for example, the container body 10 is formed such that, when the upper container body 11 and the lower container body 12 are combined and the internal storage space S is sealed, the overall size is preferably 60 mm to 150 mm, more preferably 80 mm to 100 mm in the front-to-back direction, preferably 80 mm to 200 mm, more preferably 145 mm to 165 mm in the left-to-right direction, and preferably 30 mm to 100 mm, more preferably 50 mm to 70 mm in the up-down direction. The thickness of each surface is preferably 0.5 mm to 3.0 mm, and more preferably 1.0 mm to 2.0 mm. With this size and thickness, molding efficiency is high and strength sufficient for practical use can be achieved.

[0018] (Connection) As shown in Figs. 3 and 4, the sanitary tissue paper storage container 1 is formed so as to rotate about a connecting portion 13 that connects the upper container body 11 and the lower container body 12 as a fulcrum. This allows the storage space S to be exposed to the outside, as shown in Figure 4. To cover the storage space S, the user simply rotates the upper part 11 of the container body in the opposite direction to that described above. This connection part 13 is formed to be thinner than other parts of the container body 10, so it is easy to bend, making it easy to rotate the upper part 11 of the container body relative to the lower part 12 of the container body using the connection part 13 as a fulcrum. Specifically, the connection portion 13 connecting the rear surface of the upper container body 11 and the rear surface of the lower container body 12 is a thin plate-like connection portion (thin plate-like member) having a rectangular shape that is elongated in the left-right direction.

[0019] In other words, this connection portion 13 can be bent along a fold line along the left-right direction, and by rotating the upper portion 11 of the container body using this fold line as a fulcrum (axis), the storage space S of the lower portion 12 of the container body can be exposed or shielded. In this way, the connecting portion 13 that can be bent using the supporting point is made of polypropylene. In particular, the polypropylene constituting the connecting portion 13 contains a random copolymer and a block copolymer. Since the connecting portion 13 is formed from polypropylene containing a random copolymer and a block copolymer, the connecting portion 13 is easy to bend and has durability against repeated deformation. This makes it easier to rotate the upper container body 11 relative to the lower container body 12 with the connecting part 13 as a fulcrum, making it easier to expose or cover the storage space S of the lower container body 12, making it easier to refill the sanitary tissue paper P.

[0020] Furthermore, by dividing the container body 10 into an upper container body 11 and a lower container body 12 above the vertical center, when the sanitary tissue paper P is stored in the storage space S while covered with a specified packaging, the risk of the end seal portion of the packaging being pinched between the upper container body 11 and the lower container body 12 when the storage space S is sealed can be reduced, making it even easier to refill the sanitary tissue paper P. The position where the container body 10 is divided into the upper container body 11 and the lower container body 12 may be near the center in the vertical direction.

[0021] (Top of container body) As shown in Figures 1 to 6, the upper part 11 of the container body is formed in an approximately rectangular parallelepiped shape with an approximately rectangular opening on the lower side, and a recess 112 that is concave downward is formed near the center of the top surface 111 that forms the upper surface, and an extraction section 113 having an extraction hole 113a for extracting sanitary tissue paper P from the storage space S is provided in the center of the recess 112. Furthermore, at the rear end of the recess 112, a storage recess 115 is formed in which a biasing member 114 is stored. In addition, the lower end (opening) of the upper part 11 of the container body is formed with a ring-shaped outer edge portion 116 and a ring-shaped inner edge portion 117 that is located inside the outer edge portion 116 and protrudes downward more than the outer edge portion 116. A handle 118 is formed at the lower end of the front surface of the upper portion 11 of the container body to be grasped when exposing the storage space S.

[0022] (Material of the upper part of the container body) The upper part 11 of the container body is made of a hard material. In this embodiment, polypropylene, which is a hard plastic, is used as the hard material, and the upper part 11 of the container body is made of polypropylene. In particular, the polypropylene constituting the upper part 11 of the container body contains a random copolymer and a block copolymer. Furthermore, it is desirable that the portion made of an elastic material and the portion made of a hard material, which will be described later, are integrally formed by injection molding.

[0023] (recess) The recess 112 is formed near the center of the top surface 111 in a plan view, for example, as shown in Fig. 2. Fig. 2 illustrates a case where the shape of the recess 112 is a curved, approximately rectangular shape that reaches the front end of the upper container body 11 in a plan view, but the specific shape of the recess 112 is not limited to this.

[0024] The depth of recess 112 in the vertical direction is preferably 5 mm to 20 mm when viewed from top surface 111. The size in plan view is not particularly limited as long as extraction portion 113 can be formed inside, but is preferably 40 mm to 80 mm in the front-to-back direction and 40 mm to 120 mm in the left-to-right direction.

[0025] (Ejecting part) The extraction portion 113 is formed near the center of the recess 112 in plan view, and is made of an elastic material. The extraction portion 113 here has a generally rectangular shape in plan view. Approximately in the center of the extraction part 113, a bulging part 113b that is raised in a substantially spherical shape is formed, and an extraction hole 113a is provided in the bulging part 113b. Three protruding pieces 113c protruding toward the center of the extraction portion 113 are provided on the edge of the extraction hole 113a. Furthermore, an approximately annular outer peripheral rib 113d that protrudes upward is provided on the outer edge of the removal portion 113. The outer peripheral rib 113d here has an approximately rectangular annular shape and protrudes upward.

[0026] It is desirable that the removal portion 113 is formed in the shape of a film with a thickness of 0.5 mm to 2.0 mm in the vertical direction, for example. The elastic material forming the removal portion 113, etc., can be, for example, a material having elasticity such as silicone rubber or a styrene-butadiene, polyester, polyethylene, or urethane-based TPE (Thermoplastic Elastomer), and it is desirable that the hardness be 20 to 90. If the hardness of the elastic material is lower than the above value, it is too soft and difficult to mold, which is undesirable in that molding efficiency decreases. Furthermore, if the hardness of the elastic material is higher than the above value, the removal section 113, which has the removal hole 113a for removing the sanitary tissue paper P, becomes hard, creating too much resistance, making it difficult to remove the sheets one by one, and also making it difficult to insert fingers into the storage space S when pulling out the sheets, which is undesirable. The hardness is measured according to JIS K 6253 (type A durometer).

[0027] (Ejection hole) The removal hole 113a is a hole portion that is formed in the center of the removal portion 113 in a plan view and that is connected to the storage space S. For example, in Fig. 2, the extraction hole 113a has a generally inverted Y shape, with each side of a triangle projecting inward in an arc shape, and three slits intersect at the center of gravity, connecting each vertex with the center of gravity. Of the three slits, the slit extending in the front-to-rear direction has a wider width than the other slits. The number of slits may be fewer or more; for example, the extraction hole 113a may be formed by forming two slits in a cross shape.

[0028] The removal section 113 is formed around the removal hole 113a with an elastic material, so that it can apply appropriate resistance to the sanitary tissue paper P, and functions to hold the next sanitary tissue paper P after the sanitary tissue paper P stored in the storage space S is pulled out. Furthermore, when the sanitary thin paper P is a roll sheet, the take-out unit 113 serves to cut the sanitary thin paper P at cutting perforations provided in the sanitary thin paper P.

[0029] (projection) The protruding piece 113c is a portion against which the sanitary thin paper P pulled out from the take-out hole 113a slides, and is provided to apply an appropriate resistance to the sanitary thin paper P pulled out from the take-out hole 113a. Specifically, when a user opens the opening / closing lid 2 of the sanitary tissue paper storage container 1 to remove the sanitary tissue paper P, the user reaches out from the front side of the sanitary tissue paper storage container 1 and pulls out the sanitary tissue paper P from the removal hole 113a so that the opening / closing lid 2, which is in an upright position at the back of the sanitary tissue paper storage container 1, does not interfere with the action of removing the sanitary tissue paper P, and the sanitary tissue paper P pulled out from the removal hole 113a comes into sliding contact with the protruding piece 113c on the front edge. At this time, the protrusion 113c protruding rearward from the front edge slides against the sanitary tissue paper P being pulled out from the removal hole 113a toward the front, so that the protrusion 113c applies an appropriate resistance to the sanitary tissue paper P, preventing the sanitary tissue paper P from being pulled out too far from the removal hole 113a.

[0030] In other words, the protruding piece 113c protruding rearward from the front edge applies an appropriate frictional force to the sanitary tissue paper P being pulled out toward the front from the removal hole 113a, and has the function of preventing the next sanitary tissue paper P pulled out after the sanitary tissue paper P being pulled out and used from being pulled out too far from the removal hole 113a. The next sanitary thin paper P pulled out after the sanitary thin paper P to be used will be held in the take-out hole 113a with its end pulled out at an appropriate length.

[0031] The end of the sanitary thin paper P thus held in the take-out hole 113a is supported by three protrusions, including the protrusion 113c on the front side. The removal hole 113a that holds the end of the sanitary tissue paper P is provided in the bulging portion 113b of the removal portion 113, so the tip side of each protrusion 113c is located at a higher position than the removal portion 113, which is the base surface around the bulging portion 113b. The end of the sanitary tissue paper P is supported at a higher position than the surrounding area by these protrusions 113c and held in the removal hole 113a, making it easy to pick up the sanitary tissue paper P.

[0032] (biasing member) The biasing member 114 is, for example, a strip-shaped member made of an elastic material, as shown in Fig. 2. One end of the biasing member 114 is fixed to the rear of the recess 112, and the other end of the biasing member 114 is fixed to an insertion portion 23 (described later) of the opening / closing cover 2. This biasing member 114 is arranged between the container body 1 and the opening / closing lid 2 near the part where the opening / closing lid 2 is pivotally supported on the container body 1, and the other end of the biasing member 114 presses against the underside of the opening / closing lid 2, biasing the opening / closing lid 2 to rotate in the direction exposing the removal portion 113. In this way, the biasing member 114 biases the opening / closing lid 2 in the opening direction so that it stands up, and when the user presses the button portion 3, the opening / closing lid 2 is pushed up and stands up by rotating around the connection portion with the upper part 11 of the container body as the rotation axis.

[0033] The biasing member 114 is formed in a strip shape with a width of preferably 2 mm to 30 mm, more preferably 8 mm to 10 mm, and a thickness of preferably 0.5 mm to 3.0 mm, more preferably 1.0 mm to 2.0 mm. Since the biasing member 114 is formed to this size, it is possible to easily push up the opening / closing lid 2 when the opening / closing lid 2 is opened, and the biasing member 114 can be easily folded and stored in the storage recess 115 when the opening / closing lid 2 is closed.

[0034] Furthermore, as shown in FIG. 2, the biasing member 114 is formed so as to be in an extended state when no force is applied thereto, so that when the opening / closing cover 2 is closed and the biasing member 114 is bent, for example, as shown in FIG. 8, a force is generated that tries to return the biasing member 114 to the state shown in FIG. 2. This allows the biasing member 114 to bias the opening / closing lid 2 so as to rotate it backward around the connecting portion between the opening / closing lid 2 and the upper portion 11 of the container body as the rotation axis.

[0035] (storage recess) The storage recess 115 is a recess for storing the bent portion of the biasing member 114 when the biasing member 114 is pushed downward when the opening / closing cover 2 is closed, for example, as shown in FIG. As shown in FIG. 2, the storage recess 115 is formed in the recess 112 behind the removal portion 113 and near the front of the biasing member 114, so as to be recessed further downward than the recess 112. The shape of the storage recess 115 is not particularly limited, but for example, it may be an approximately rectangular parallelepiped that is longer in the left-right direction than in the front-to-back direction, and may have enough space to store the spring member 114 that is pressed in and bent by the opening / closing lid 2 when the opening / closing lid 2 is closed.

[0036] (Outer edge / inner edge) The outer edge portion 116 is, for example, annular as shown in FIGS. 4 to 6, and is formed at the lower end of the upper portion 11 of the container body. 4 to 6, the inner edge portion 117 is annular, and is provided at the lower end of the upper container body 11 more inward than the outer edge portion 116, and protrudes downward than the outer edge portion 116. The inner edge portion 117 is formed so as to fit into a recessed groove portion 121 of the lower container body 12, which will be described later, when the storage space S is sealed. The outer edge 116 and the inner edge 117 are part of the upper part 11 of the container body, and are therefore made of polypropylene containing a random copolymer and a block copolymer. Furthermore, the groove portion 121 (outer wall portion 1211, inner wall portion 1212) described later is also formed from the same polypropylene, so that the inner edge portion 117 of the upper container body 11 slides into the groove portion 121 of the lower container body 12, making it easy for it to fit in, and the upper container body 11 and the lower container body 12 come into close contact with each other, thereby maintaining the airtightness of the storage space S in an optimal manner.

[0037] (Handle) 1 to 8, the handle portion 118 is formed integrally with the upper container body 11 at the center of the front surface of the upper container body 11, protruding in an arch shape from the front surface thereof, so that a gap a is formed between the handle portion 118 and the front surface of the container body 10, whereby a finger can be hooked. When exposing the storage space S, the handle portion 118 is grasped and the upper container body 11 is rotated around the connection portion 13 as a fulcrum. Furthermore, two locking portions 1181 are provided on the inner surface of the handle portion 118.

[0038] The shape of the handle portion 118 does not have to be an arch-shaped protruding shape, and may be any shape as long as it protrudes from the front surface of the upper portion 11 of the container body and has a gap a between it and the front surface. Furthermore, when the upper container body 11 and the lower container body 12 are engaged with each other, the handle 118 overlaps in the front-to-rear direction with an engaging protrusion 123 (described later) provided on the lower container body 12. This results in a structure in which the engaging protrusion 123 is not visible from the front.

[0039] (Latching part) The locking portion 1181 is provided on the front surface of the upper portion 11 of the container body, as shown in, for example, FIGS. Specifically, two locking portions 1181 are provided at a predetermined interval along the left-right direction on the inner surface of the handle portion 118, and are formed to engage with the engaging protrusions 123 of the lower part 12 of the container body when the storage space S is sealed, thereby maintaining the sealed state. The distance between the two locking portions 1181 is arbitrary, but may be approximately the width of a typical user's finger. Specifically, they are spaced apart between 5 mm and 25 mm, and more preferably between 18 mm and 25 mm. This engaging portion 1181 is a part of the upper portion 11 of the container body, and is therefore made of polypropylene containing a random copolymer and a block copolymer. Furthermore, since the engaging protrusion 123 described later is also formed from the same polypropylene, the locking portion 1181 is designed to suitably engage with the engaging protrusion 123, and the upper container body 11 can be fitted suitably into the lower container body 12 to shield the storage space S. The number of locking portions 1181 is not limited to two, and may be provided at positions spaced apart on either side of the center of the inner surface of the handle portion 118 in the left-right direction. For example, two locking portions may be provided on each side (four in total).

[0040] (Bottom of container body) As shown in FIG. 4, the container body lower portion 12 is formed in a roughly rectangular parallelepiped shape with a roughly rectangular opening on the upper side, and a ring-shaped recessed groove portion 121 is formed on the edge of the upper end. In addition, a non-slip portion 122 is formed on the bottom of the lower container body 12 to prevent slipping when the sanitary tissue paper P stored in the storage space S is taken out through the take-out hole 113a. Further, near the center of the upper end of the front surface of the container body lower part 12, an engagement protrusion 123 is formed integrally with the container body lower part 12 and protrudes forward.

[0041] (Material of the bottom of the container body) The container body lower part 12 is formed of the same hard material as that used for the container body upper part 11. In this embodiment, polypropylene, which is a hard plastic, is used as the hard material, and the container body lower part 12 is formed of polypropylene. In particular, the polypropylene constituting the lower part 12 of the container body contains a random copolymer and a block copolymer.

[0042] (concave groove) The groove portion 121 is annular, for example, as shown in Figure 4, and is formed at the upper end of the lower container body 12 so that the inner edge portion 117 of the upper container body 11 fits into it when shielding the storage space S, and is provided with an outer wall portion 1211 and an inner wall portion 1212.

[0043] (Outer wall / inner wall) The outer peripheral wall portion 1211 is formed as an outer peripheral wall surface of the container body lower portion 12, and when the storage space S is shielded, it abuts against the outer edge portion 116 of the container body upper portion 11. The inner wall portion 1212 is formed as the inner wall surface of the lower portion 12 of the container body, and as shown in Figure 4, is provided with first guide portions 1212a provided at both ends of the rear surface in the left-right direction so as to protrude upward beyond the outer wall portion 1211, and second guide portions 1212b provided in multiple numbers on the rear surface side. The inner edge 117 of the upper part 11 of the container body slides between the outer peripheral wall 1211 and the inner peripheral wall 1212 of the recessed groove 121, thereby maintaining the sealing of the storage space S. The recessed groove 121 (outer peripheral wall 1211, inner peripheral wall 1212) is part of the container body lower part 12, and is therefore made of polypropylene containing a random copolymer and a block copolymer. As mentioned above, the groove portion 121 (outer wall portion 1211, inner wall portion 1212) and the inner edge portion 117, both of which are formed from polypropylene containing random copolymers and block copolymers, are easily brought into close contact with each other, and the upper container body portion 11 and the lower container body portion 12 are brought into close contact with each other, thereby maintaining the airtightness of the storage space S in an optimal manner.

[0044] (1st and 2nd guide sections) As shown in FIG. 4, the first guide portion 1212a is provided at both left and right ends of the rear surface of the container body lower portion 12, extending over the left and right surfaces, respectively, and is taller in the vertical direction than the outer peripheral wall portion 1211 and the second guide portion 1212b. The second guide portions 1212b are wavy and provided in plurality along the left-right direction on the rear surface of the container body lower portion 12, and are higher in the up-down direction than the outer peripheral wall portion 1211 but lower than the first guide portions 1212a.

[0045] (Anti-slip part) The anti-slip portion 122 is formed at the bottom of the container body lower portion 12 by an elastic material surrounded by a hard material, for example, as shown in FIG. Specifically, as shown in Figures 6 to 8, anti-slip portions 122 made of an elastic material and having an approximately circular shape are provided at the four corners of the bottom of the lower part of the container body 12, and these anti-slip portions 122 are exposed to the outer surface from the bottom of the lower part of the container body 12. The anti-slip part 122 exposed on the outer surface of the container body lower part 12 is adapted to come into contact with the placement surface on which the storage container 1 is placed, and serves as an anti-slip role when the storage container 1 is placed on the placement surface.

[0046] (Engaging protrusion) The engaging protrusion 123 is a protrusion that protrudes forward and is formed integrally with the lower container body 12 at approximately the center of the upper end of the front surface of the lower container body 12, as shown in Figures 4 and 6, for example, and two locking portions 1181 are engaged with it when the storage space S is sealed. The engagement protrusion 123 is formed so that its length in the left-right direction is longer than the distance between the two locking portions 1181. The engaging projection 123 is a part of the container body lower part 12 and is therefore made of polypropylene containing a random copolymer and a block copolymer. As mentioned above, the engaging protrusion 123 and the locking portion 1181, both of which are made of polypropylene containing random copolymers and block copolymers, are designed to engage with each other appropriately, so that the upper container body 11 can be fitted into the lower container body 12 appropriately to shield the storage space S.

[0047] (Opening and closing lid) As shown in Figs. 1 to 5, the opening / closing lid 2 is a member rotatably attached to the rear of the recess 112 in the upper portion 11 of the container body, and has a flattened, curved, and generally rectangular shape. The opening / closing lid 2 is pivotally supported on the rear side of the container body 1 so as to be switchable between a closed state in which the removal portion 113 is covered and an open state in which the removal portion 113 is exposed. The cover 2 has a cover-side locking portion 21 on the front side when in the closed state, and an insertion portion 23 on the underside of the cover 2 into which the other end of the biasing member 114 is inserted. The underside of the cover 2 is provided with a cover-side sealing ring 22 as a substantially annular cover back rib that protrudes downward when the cover is closed and whose lower edge abuts against the removal portion 113 . The opening / closing lid 2 is formed so that its shape in a planar view when closed is approximately the same as the shape of the recess 112 in the upper part 11 of the container body in a planar view, excluding the part where the button part 3 is provided, and is formed so that it can be fitted into the recess 112 when closed and is flush with the top surface part 111.

[0048] (lid material) The opening / closing lid 2 is made of the same hard material as that used for the container body 10 .

[0049] (Lid locking part) As shown in Figures 2, 3 and 5, the cover-side locking portion 21 is a claw-shaped portion that protrudes forward from the cover 2. The cover-side locking portion 21 engages with a button-side locking portion 313 (described below) formed on the button portion 3, thereby locking the cover 2 in the closed state. When the user presses the button portion 3, the cover-side locking portion 21 and the button-side locking portion 313 disengage, and the biasing force generated by the biasing member 114 causes the cover 2 to enter the open state. Furthermore, the open / close cover 2 can be closed by rotating the open / close cover 2 in the opposite direction to when it is open, and engaging the open / close cover side locking portion 21 with the button side locking portion 313 (described later).

[0050] The shape of the opening / closing cover side locking portion 21 is not limited to the claw shape shown in Figures 2, 3 and 5, as long as it engages with the button side locking portion 313 to lock the opening / closing cover 2 in the closed state, and when the user presses the button portion 3, the opening / closing cover side locking portion 21 and the button side locking portion 313 disengage.

[0051] (Opening / closing lid side sealing ring part) The opening / closing lid side sealing ring portion 22 has an approximately rectangular ring shape, as shown in Figures 2 and 5, and is formed in the approximate center of the underside of the opening / closing lid 2 so that it protrudes downward when the opening / closing lid 2 is closed and the lower edge of the opening / closing lid side sealing ring portion 22 abuts against the removal portion 113 formed in the upper part 11 of the container body. As shown in Figure 8, this opening / closing lid side sealing ring portion 22 is positioned so that its lower edge abuts between the removal hole 113a and the outer peripheral rib 113d in the removal portion 113, at a position closer to the outer peripheral rib 113d and away from the removal hole 113a. Specifically, the lower edge of the opening / closing lid side sealing ring portion 22 is arranged to contact the outer peripheral rib 113d and abut against the removal portion 113. Here, as shown in Figure 8, the lower edge of the opening / closing lid side sealing ring portion 22 is in contact with the inside of the outer peripheral rib 113d and abuts against the removal portion 113. In addition, the lower edge of the opening / closing lid side sealing ring portion 22 is in elastic contact with the removal portion 113, which is formed from an elastic material, making it easy for the removal portion 113 and the lower edge of the opening / closing lid side sealing ring portion 22 to come into close contact with each other.

[0052] In particular, the opening / closing lid side sealing ring portion 22 serving as the lid back rib is formed so that the vertical dimension in the closed state is longer the closer it is to the rear side where the opening / closing lid 2 is pivotally supported on the container body 1, as shown in Figures 2 and 8. Specifically, as shown in Figure 2, in the opening / closing lid side sealing ring portion 22, which has a rectangular ring shape, the rear rib 22a, which is located on the rear side in the closed state, has a longer vertical dimension in the closed state than the front rib 22b, which is located on the front side in the closed state. Furthermore, a pair of left and right ribs 22c connecting the rear rib 22a and the front rib 22b are generally trapezoidal in side view, and the vertical dimension gradually increases from the front to the rear when the lid is closed. For example, the vertical length of the rear rib 22a in the closed state is formed to be 1 to 2.5 mm longer than the vertical length of the front rib 22b.

[0053] Since the opening / closing lid side sealing ring portion 22 serving as the lid back rib has such a shape, the lower end edge of the opening / closing lid side sealing ring portion 22 and the removal portion 113 are surely in contact with each other. For example, in this sanitary tissue paper storage container 1, a spring member 114 is arranged at the rear position where the opening / closing lid 2 is pivotally supported on the container body 1, and the spring force of the spring member 114 pushes up the rear side of the opening / closing lid 2 when in the closed state, causing the top surface of the opening / closing lid 2 to have a slight downward slope from the rear side to the front side. Even when the opening / closing lid 2 is in a position where the rear side is raised so that its upper surface slopes downward from the rear side to the front side, the opening / closing lid side sealing ring portion 22 on the underside of the opening / closing lid 2 is formed longer on the rear side where the opening / closing lid 2 is journaled to the container body 1, so that the opening / closing lid side sealing ring portion 22 can maintain contact with the removal portion 113 around the entire circumference of the lower edge.

[0054] In other words, even if the rear side of the opening / closing lid 2 is pushed up by the biasing force of the biasing member 114 in the closed state and the rear side of the opening / closing lid 2 takes on a raised position, the opening / closing lid side sealing ring portion 22, which serves as a lid back rib, is formed longer on the rear side where the opening / closing lid 2 is pivotally supported on the container body 1 so that the lower edge of the opening / closing lid side sealing ring portion 22 does not separate from the removal portion 113.

[0055] The lower edge of the opening / closing lid side sealing ring portion 22 abuts at a position between the removal hole 113a and the outer peripheral rib 113d in the removal portion 113, closer to the outer peripheral rib 113d than the removal hole 113a, thereby preventing deformation of the removal hole 113a and the edge of the removal hole 113a (protrusion 113c) and not affecting the ease of removal of the sanitary tissue paper P. Furthermore, if the lower edge of the opening / closing lid side sealing ring portion 22 is in contact with the outer peripheral rib 113d, the outer peripheral rib 113d will protrude upward, thereby ensuring more reliable contact between the lower edge of the opening / closing lid side sealing ring portion 22 and the removal portion 113. In particular, if the lower edge of the opening / closing lid side sealing ring portion 22 is in contact with the inside of the outer peripheral rib 113d and abuts against the removal portion 113, as shown in Figure 8, the opening / closing lid side sealing ring portion 22 will fit inside the outer peripheral rib 113d, making it possible for the opening / closing lid side sealing ring portion 22 to cover the removal hole 113a of the removal portion 113 with good sealing properties.

[0056] (insertion part) The insertion portion 23 is, for example, as shown in FIGS. 2 and 5, for inserting and fixing a biasing member 114 into the rear end portion of the opening / closing cover 2.

[0057] (Button section) As shown in FIG. 8, the button section 3 has, for example, a button mounting section 32 provided on the container body 10 (container body upper section 11), a button 31 mounted on the button mounting section 32, and a button elastic member 33 interposed between the button 31 and the button mounting section 32 so as to be elastically deformable. The button 31 and the button mounting portion 32 are formed from the same hard material as that used in the container body 10, and the button elastic member 33 is formed from the same elastic material as the removal portion 113, the biasing member 114, etc. When the user presses the button 31 of the button section 3, the opening / closing cover 2 is released from the engagement of the button 31, and the opening / closing cover 2 is pushed up by the biasing force of the biasing member 114 and opened.

[0058] (Button mounting part) The button attachment portion 32 is a portion for attaching the button 31, provided in a portion in front of the recess 112 of the upper portion 11 of the container body where the button portion 3 is provided, as shown in FIG. On both the left and right sides of the button attachment portion 32, shaft holes (not shown) are formed into which button shafts 312 (shaft portions 312b) of the buttons 31, which will be described later, are inserted. The button mounting portion 32 is provided with a contact surface 32a against which the tip of a button elastic member 33 (described later) abuts. The contact surface 32a faces the bottom surface of the button 31 attached to the button mounting portion 32.

[0059] (button) As shown in Figure 8, the button 31 is a member formed independently of the button mounting portion 32, and includes an upper surface 311 that is pressed by the user, button shafts 312, 312 provided on both the left and right sides of the button 31, a button side locking portion 313 that engages with the opening / closing cover side locking portion 21 of the opening / closing cover 2 to lock the opening / closing cover 2 in the closed state, and elastic member support portions 314, 314 that support the button elastic member 33 on the underside of the button 31.

[0060] (Top part) As shown in Figures 1 and 8, the upper surface portion 311 is formed so that the rear base end portion 311b side is linear and the front tip portion 311a side is arc-shaped in a plan view, and the tip portion 311a is formed so as to protrude forward from the recess 112. A gap b is formed between the tip end 311a of the top surface portion 311 and the upper portion 11 of the container body. The size of the upper surface portion 311 is determined according to the size of the portion of the recess 112 that is not covered by the opening / closing lid 2, but it is desirable that the longest part in the front-to-back direction has a length of 10 mm to 30 mm, and the longest part in the left-to-right direction has a length of 30 mm to 100 mm. The tip portion 311a of the button 31 may be formed to have a straight line shape.

[0061] The upper surface portion 311 is formed so as to be inclined downward from the base end portion 311b side toward the tip end portion 311a side. The inclination angle of this upper surface portion 311 is preferably 6 to 10 degrees. The inclination angle of the upper surface portion 311 may be different between the base end portion 311b side and the tip end portion 311a side, and may be formed into a two-stage inclination, for example, such that the inclination angle on the base end portion 311b side is 6 degrees to 8 degrees and the inclination angle on the tip end portion 311a side is 8 degrees to 10 degrees.

[0062] (Button shaft) As shown in FIG. 8, the button shaft 312 has a base 312a provided on the underside of the upper surface 311 and a shaft 312b extending outward from the base 312a, and is provided in pair on the left and right sides of the button 31. The pair of button shafts 312 are provided symmetrically, and each shaft portion 312b extends along the same axis in directions away from each other. The shaft portion 312b of this button shaft 312 is inserted into a shaft hole (not shown) of the button mounting portion 32, and the button 31 is rotatably supported by the button mounting portion 32.

[0063] (Button side locking part) The button side locking portion 313 is a recess formed behind the button 31, as shown in Figure 8, and is configured so that the opening / closing lid side locking portion 21 formed on the opening / closing lid 2 engages with the button side locking portion 313 to lock the opening / closing lid 2 in the closed state. Furthermore, when the user presses the button portion 3, the opening / closing cover side locking portion 21 disengages, and the opening / closing cover 2 is pushed up and opened by the biasing force generated by the biasing member 114. The shape of the button side locking portion 313 can be any shape that locks the opening / closing lid 2 in the closed state and disengages the button side locking portion 313 from the opening / closing lid side locking portion 21 when the user presses the button portion 3, and is not limited to a recess as shown in the figure, but may be, for example, a claw portion with which the opening / closing lid side locking portion 21 engages.

[0064] (Elastic member support part) As shown in FIG. 8, the elastic member support portions 314 are, for example, plate-like protruding pieces provided so as to protrude downward from the lower surface of the upper surface portion 311, and a pair of them are provided at a distance in the front and rear. The button elastic member 33 is disposed between the pair of elastic member support portions 314, 314. Here, the front and rear elastic member support portions 314 are formed to have different sizes, with the front elastic member support portion 314 being smaller than the rear elastic member support portion 314, but the front elastic member support portion 314 may be formed to be larger than the rear elastic member support portion 314, or may be formed to be the same size.

[0065] (Button elastic material) The button elastic member 33 is a plate-like member made of an elastic material and capable of elastic deformation. The button elastic member 33 is disposed on the underside of the button 31 in such a manner that the upper end side of the button elastic member 33 is sandwiched and supported between a pair of elastic member support portions 314, 314. The button elastic member 33 here has a shape that is oriented long in the left-right direction relative to the button 31, and the button elastic member 33 arranged on the button 31 extends along the front edge of the tip portion 311a side of the button 31. It is preferable that the button elastic member 33 be arranged over substantially the entire width of the button 31. When the button 31, which supports the button elastic member 33 by a pair of elastic member support portions 314, 314, is attached to the button mounting portion 32, the tip portion, which is the free end of the button elastic member 33, is abutted against the abutment surface portion 32a of the button mounting portion 32. In particular, since the upper end side of the button elastic member 33 is supported by a pair of elastic member support portions 314, 314, the tip portion of the lower end side of the button elastic member 33 abuts against the abutment surface portion 32a of the button mounting portion 32 in a stable posture.

[0066] (Button operation) As described above, with the button-side locking portion 313 of the button 31 engaged with the cover-side locking portion 21 of the cover 2, the button 31 locks the cover 2 in the closed position. When the button 31 that holds the opening / closing lid 2 in the closed state is pressed, the button elastic member 33 is elastically deformed, causing the button 31 to rotate, and the position of the button 31 is changed so that the tip end 311a of the button 31 lowers, thereby releasing the button 31 from holding the opening / closing lid 2 and opening the opening / closing lid 2 to the open state. When the pressure on the button 31 is released, the tip portion 311a of the button 31 rises due to the restoring force of the button elastic member 33, and the button 31 returns to its original position.

[0067] [Effects of the embodiment] The sanitary tissue paper storage container 1 of this embodiment comprises a container body 10 having a removal section 113 with a removal hole 113a for removing the sanitary tissue paper P, a lid body 2 pivotally supported on the rear side of the container body 10 so as to be switchable between a state in which the removal section 113 is covered and a state in which the removal section 113 is exposed, a biasing member 114 disposed between the lid body 2 and the container body 10 at the position on the side where the lid body 2 is pivotally supported on the container body 10 and biases the lid body 2 to rotate in a direction that exposes the removal section 113, and a biasing member 114 on the front side of the container body 10. The lid body 2 is provided with a button section 3 and the like for switching between a closed state in which the lid body 2 covers the removal section 113 and an open state in which the lid body 2 exposes the removal section 113, and the underside of the lid body 2 is provided with a roughly annular opening / closing lid side sealing ring section 22 which protrudes downward in the closed state and abuts its lower edge outside the removal hole 113a in the removal section 113, and the opening / closing lid side sealing ring section 22 is formed so that the vertical dimension in the closed state is longer the closer it is to the side where the lid body 2 is journaled to the container body 10.

[0068] In the sanitary tissue paper storage container 1 of this embodiment, a spring member 114 is arranged at the rear position where the opening / closing lid 2 is pivotally supported on the container body 1, so that the rear side of the opening / closing lid 2 may be pushed up by the spring force of the spring member 114 when the lid is closed. Even when the rear side of the opening / closing lid 2 is pushed up and assumes a floating position, the opening / closing lid side sealing ring portion 22 provided on the underside of the opening / closing lid 2 is formed longer on the rear side where the opening / closing lid 2 is journaled to the container body 1, so that the lower edge of the opening / closing lid side sealing ring portion 22 does not move away from the removal portion 113, and can maintain contact with the removal portion 113 around the entire circumference of the lower edge of the opening / closing lid side sealing ring portion 22. In other words, the sanitary tissue paper storage container 1 of this embodiment has good sealing properties, so that even if the rear side of the opening / closing lid 2 is pushed up by the spring member 114, no gap is formed between the opening / closing lid side sealing ring portion 22 and the removal portion 113. A sanitary tissue paper storage container 1 with such good sealing properties makes it difficult for the water content of the chemical solution impregnated in the sanitary tissue paper P stored inside to evaporate, thereby preventing the sanitary tissue paper P from drying out.

[0069] In addition, an approximately annular outer peripheral rib 113d that protrudes upward is provided on the outer edge of the removal section 113, and the lower edge of the opening / closing lid side sealing ring section 22 abuts at a position between the removal hole 113a in the removal section 113 and the outer peripheral rib 113d, close to the outer peripheral rib 113d, thereby preventing deformation of the removal hole 113a and the protrusion 113c, thereby not affecting the ease of removal of the sanitary tissue paper P and preventing sanitary tissue paper P such as wet wipes (moist tissues) stored inside the sanitary tissue paper storage container 1 from drying out.

[0070] Furthermore, if the lower edge of the opening / closing lid side sealing ring portion 22 is in contact with the outer peripheral rib 113d, the outer peripheral rib 113d will protrude upward, resulting in more reliable contact between the lower edge of the opening / closing lid side sealing ring portion 22 and the removal portion 113, thereby improving the sealing performance, thereby making it possible to make it more difficult for sanitary tissue paper P such as wet wipes (moist tissues) stored inside the sanitary tissue paper storage container 1 to dry out.

[0071] As described above, the sanitary tissue paper storage container 1 of this embodiment has good sealing properties, and the moisture of the medicinal liquid impregnated in the sanitary tissue paper P stored inside is less likely to evaporate, so sanitary tissue paper P such as wet wipes can be stored without drying out.

[0072] In the above embodiment, the opening / closing lid side sealing ring portion 22 as the lid back rib has an approximately rectangular ring shape, but the present invention is not limited to this and can be modified appropriately depending on the shape of the removal portion 113. For example, the opening / closing lid side sealing ring portion 22 may have an approximately circular ring shape.

[0073] Furthermore, it goes without saying that other specific detailed structures and the like can be modified as appropriate. [Explanation of symbols]
