[0013] 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.

[0014] In the following, 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 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", and the axis along the front-rear direction is the X-axis, the axis along the left-right direction is the Y-axis, and the axis along the up-down direction is the Z-axis. 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, the following description will be based on the state in which the upper and lower parts of the container body are combined and the storage space S is closed, as shown in Figure 1.

[0015] [Configuration of the embodiment] (Overall composition) As shown in Figures 1 to 4, the sanitary tissue paper storage container 1 includes a container body 10 having an extraction hole 113a for removing the sanitary tissue paper P stored inside, an opening / closing lid 2 which is rotatably attached to the container body 10 and is a lid body for opening and closing the extraction hole 113a, and a button section 3 which switches between a closed lid state in which the opening / closing lid 2 blocks the extraction hole 113a and an open lid state in which the opening / closing lid 2 opens the extraction hole 113a. A storage space S in which sanitary tissue paper P is stored is formed inside this sanitary tissue paper storage container 1.

[0016] (hygienic tissue paper) As the sanitary thin paper P, for example, a so-called pop-up type sheet is used, in which small wet sheets (wet tissues) are alternately folded and stacked so that when one wet sheet (wet tissue) is pulled out, the next wet sheet (wet tissue) is also pulled out. In addition, for example, a roll sheet can be used in which a long wet sheet (wet tissue) with perforations at regular intervals along its length is wound into a roll and the roll is cut along the perforations for use.

[0017] (Container body) As shown in Figures 1 to 4, for example, the container body 10 is formed as a roughly rectangular parallelepiped that is longer in the left-right direction than in the front-to-back and up-down directions, and is divided into two parts, upper and lower, above the center in the up-down direction, to form an upper container body 11 that constitutes the upper part of the container body 10, and a lower container body 12 that constitutes the lower part of the container body 10. The upper and lower container body sections 11 and 12 are connected to each other by a connecting section 13 at the rear surface of the container body 10 . The upper container body portion 11, the lower container body portion 12, and the connection portion 13 are integrally formed by a method such as injection molding (two-color molding).

[0018] As shown in Figures 1 to 4, for example, the container body 10 is formed such that, when the container body upper part 11 and the container body lower part 12 are combined and the internal storage space S is closed, the container body 10 as a whole has a size of 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 to 3.0 mm, and more preferably 1.0 to 2.0 mm. This size and thickness ensure high molding efficiency and achieve sufficient strength for practical use.

[0019] (Connection) 3 and 4, the sanitary tissue paper storage container 1 is formed to rotate about a connection part 13 that connects the upper container body 11 and the lower container body 12. This allows the storage space S to be exposed to the outside, as shown in FIG. Moreover, when closing the storage space S, the user only needs to rotate the upper part 11 of the container body in the opposite direction to that described above. This connection portion 13 is formed to be thinner than other portions of the container body 10, and is therefore easier to bend, making it easier to rotate the upper portion 11 of the container body relative to the lower portion 12 of the container body using the connection portion 13 as a fulcrum.

[0020] Although productivity will decrease, it is also possible to form the upper container body 11 and the lower container body 12 as separate bodies and then connect them rotatably by means of a hinge or the like. In addition, 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 material, the risk of the end seal portion of the packaging material being pinched between the upper container body 11 and the lower container body 12 when the storage space S is closed 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 up-down direction.

[0021] (Upper part of container body) The upper part 11 of the container body is formed, for example, as shown in Figures 1 to 6, into an approximately rectangular parallelepiped shape with a roughly rectangular opening on the lower side, and a recess 112 that is concave downward is formed near the center of the top surface portion 111 that forms the upper surface, and an extraction portion 113 having an extraction hole 113a for removing 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 in which a biasing member 114 is stored is formed. 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 gripped 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, which is a hard material. As the hard material, for example, hard plastics such as PE (polyethylene), PP (polypropylene), POM (polyacetal), ABS (Acrylonitrile Butadiene Styrene) resin, etc. can be used. Moreover, it is preferable that the portion made of an elastic material (described later) and the portion made of a hard material are integrally formed by injection molding (two-color 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 in which the shape of the recess 112 is a curved, approximately rectangular shape that reaches the front end of the container body upper portion 11 in a plan view, but the specific shape of the recess 112 is not limited thereto.

[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 a plan view is not particularly limited as long as removal portion 113 can be formed therein, but is preferably 40 mm to 80 mm in the front-rear direction and 40 mm to 120 mm in the left-right direction.

[0025] (Ejecting part) The removal portion 113 is formed near the center of the recess 112 when viewed in a plane, and is a portion made of an elastic material. A roughly spherical bulge 113b is formed approximately in the center of the removal portion 113, and a removal hole 113a is provided in the bulge 113b. Additionally, the edge of the removal hole 113a is provided with three protruding pieces 113c protruding from the edge on the front side toward the center of the removal portion 113.

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

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

[0028] The removal section 113 has an elastic material surrounding the removal hole 113a, which allows it to apply an appropriate resistance to the sanitary thin paper P and serves the function of holding the next sanitary thin paper P after the sanitary thin 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 outlet hole 113a comes into sliding contact, and is provided to provide an appropriate resistance to the sanitary thin paper P pulled out from the outlet 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 rear of the sanitary tissue paper storage container 1, does not get in the way of 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 protrusion 113c on the front edge. At this time, the protrusion 113c protruding backward from the front edge slides against the sanitary thin paper P as it is pulled out toward the front from the removal hole 113a, so that the protrusion 113c applies an appropriate resistance to the sanitary thin paper P, preventing the sanitary thin paper P from being pulled out too far from the removal hole 113a.

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

[0031] Further, 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 thin paper P is provided in the bulging portion 113b of the removal portion 113, so that the tip side of each protrusion 113c is at a higher position than the removal portion 113, which is the base surface around the bulging portion 113b. And, because the end of the sanitary thin paper P is supported at a higher position than the surrounding area by such protrusions 113c and held in the removal hole 113a, the sanitary thin paper P can be easily picked up.

[0032] (urging member) The biasing member 114 is, for example, a band-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 biases the opening / closing lid 2 in the opening direction so as to stand 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 portion 11 of the container body as the rotation axis.

[0033] The biasing member 114 is formed in a band shape having 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 open, 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] In addition, as shown in FIG. 2, the biasing member 114 is formed 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 as shown in FIG. 8, for example, a force is generated that attempts to return the biasing member 114 to the state shown in FIG. 2. This makes it possible for the biasing member 114 to bias the opening / closing lid 2 so as to rotate it backward around the connection 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 with the opening / closing cover 2 closed, as shown in FIG. As shown in FIG. 2, the storage recess 115 is formed behind the removal portion 113 within the recess 112 and in the vicinity of 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 a roughly rectangular parallelepiped shape that is longer in the left-right direction than in the front-to-back direction, and may have enough space to store the biasing 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 portion of the upper portion 11 of the container body. 4 to 6, the inner edge portion 117 is annular, is provided on the inside of the outer edge portion 116 at the lower end of the container body upper portion 11, and protrudes downward from the outer edge portion 116. The inner edge portion 117 is formed so as to enter a recessed groove portion 121 of the container body lower portion 12, which will be described later, when the storage space S is closed.

[0037] (Handle) 1 to 9, the handle portion 118 is integral with the container body upper portion 11 and protrudes from the front surface in an arch shape at the center of the front surface of the container body upper portion 11, so that a gap a is formed between the handle portion 118 and the front surface of the container body 10, allowing fingers to be hooked therein. When exposing the storage space S, the handle portion 118 is grasped and the container body upper portion 11 is rotated with 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, but 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. In addition, when the container body upper part 11 and the container body lower part 12 are engaged with each other, the handle part 118 is adapted to overlap with an engagement protrusion 123 (described later) provided on the container body lower part 12 in the front-rear direction. This results in a structure in which the engagement protrusion 123 is not visible from the front.

[0039] (Latching part) As shown in Figures 4 and 6 to 9, for example, 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 engagement protrusion 123 of the lower part 12 of the container body when the storage space S is closed, thereby maintaining the closed state. The distance between the two locking portions 1181 is arbitrary, but may be about the width of a typical user's finger. Specifically, the locking portions 1181 are spaced apart from each other by 5 mm to 25 mm, and more preferably, are spaced apart from each other by 18 mm to 25 mm. The number of locking portions 1181 is not limited to two, and may be provided at positions spaced apart on either side of the left-right center of the inner surface of handle portion 118, for example, two on each side (four in total).

[0040] (Bottom of container body) As shown in FIG. 4, the container body lower portion 12 is formed, for example, in a substantially rectangular parallelepiped shape with a substantially rectangular opening at its 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 portion 12 of the container body to prevent the sanitary thin paper P stored in the storage space S from slipping when being removed from the removal hole 113a. Further, near the center of the upper end of the front surface of the lower portion 12 of the container body, an engagement protrusion 123 is formed integrally with the lower portion 12 of the container body and protrudes forward.

[0041] (Material of the bottom of the container body) The lower container body portion 12 is formed from the same hard material as that used in the upper container body portion 11 .

[0042] (concave groove) The groove portion 121 is, for example, annular 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 engages with it when closing the storage space S, and has an outer peripheral wall portion 1211 and an inner peripheral 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 closing the storage space S, 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 FIG. 4, includes first guide portions 1212a provided at both left and right ends of the rear surface so as to protrude upward beyond the outer wall portion 1211, and second guide portions 1212b provided in multiple locations on the rear surface side. The inner edge portion 117 of the upper portion 11 of the container body slides between the outer peripheral wall portion 1211 and the inner peripheral wall portion 1212, thereby maintaining the storage space S airtight.

[0044] (First and second guide parts) 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 across the left and right surfaces, respectively, and is higher 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 multiple numbers 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 circumferential 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 lower portion 12 of the container body from an elastic material surrounded by a hard material, and has a shape such that, for example, as shown in FIG. 4, two straight lines connecting the opposing vertices of a rectangle intersect at the center of gravity, and arcs are drawn at the two corners formed by the two straight lines that extend in the left-right direction. In addition, the four ends of the two straight lines are circular, and for example, as shown in Fig. 7, a circular portion is exposed on the outer surface side from the bottom of the container body lower portion 12. Only the elastic material of the circular portion exposed on the outer surface side of the container body lower portion 12 comes into contact with the mounting surface on which the storage container 1 is placed, and serves as a mounting portion 1221 that acts as an anti-slip surface when the storage container 1 is placed on the mounting surface.

[0046] (Engaging protrusion) The engagement 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 engages with the two locking portions 1181 when the storage space S is closed. 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.

[0047] (Opening and closing lid) The opening / closing lid 2 is, for example, as shown in Figs. 1 to 5, a member rotatably attached to the rear of the recess 112 of the upper portion 11 of the container body, and has a generally flattened, curved rectangular shape. The opening / closing cover 2 has an opening / closing cover side locking portion 21 on the front side when in the closed state, and has an opening / closing cover side sealing ring portion 22 on the underside of the opening / closing cover 2, and an insertion portion 23 into which a biasing member 114 is inserted. In addition, 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, so that it can be fitted into the recess 112 when the lid is closed and is formed so as to be flush with the top surface part 111.

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

[0049] (Lid locking part) The opening / closing cover side locking portion 21 is a claw-shaped portion that protrudes forward of the opening / closing cover 2, as shown in Figures 2, 3 and 5, for example. The opening / closing cover 2 is locked in the closed state by engaging with a button side locking portion 313 (described later) formed on the button portion 3. When the user presses the button portion 3, the opening / closing cover side locking portion 21 and the button side locking portion 313 are disengaged, and the opening / closing cover 2 is opened by the biasing force generated by the biasing member 114. 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 may be any shape 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 engagement between the opening / closing cover side locking portion 21 and the button side locking portion 313 is released, and is not limited to the claw shape as shown in Figures 2, 3 and 5.

[0051] (Opening / closing lid side sealing ring part) The opening / closing lid side sealing ring portion 22 has a roughly rectangular ring shape, for example, as shown in Figures 2 and 5, and protrudes downward when the opening / closing lid 2 is closed. As shown in Figure 8, the edge of the opening / closing lid side sealing ring portion 22 is formed in the approximate center of the underside of the opening / closing lid 2 so as to contact the outer periphery of the removal portion 113 formed in the upper part 11 of the container body.

[0052] (Insertion part) The insertion portion 23 is, for example, as shown in FIG. 2 and FIG. 5, for inserting and fixing a biasing member 114 into the rear end portion of the opening / closing cover 2.

[0053] (Button section) The button portion 3, for example, as shown in Figures 8 and 9, has a button mounting portion 32 provided on the container body 10 (container body upper portion 11), a button 31 attached to the button mounting portion 32, and a button elastic member 33 interposed between the button 31 and the button mounting portion 32 so as to be elastically deformable. The button 31 and the button attachment 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 lock of the opening / closing cover 2 by the button 31 is released, and the opening / closing cover 2 is pushed up by the biasing force of the biasing member 114 and opened.

[0054] (Button mounting part) The button attachment portion 32 is a mounting location for 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 Figs. 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 a 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.

[0055] (button) The button 31, as shown in Figures 8 to 10, for example, 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.

[0056] (Top part) As shown in Figures 1, 8 to 10, for example, the upper surface portion 311 is formed so that the rear base end portion 311b side is straight 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.

[0057] Moreover, 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 degrees to 10 degrees. The inclination angle of upper surface portion 311 may be different between base end portion 311b and tip end portion 311a. For example, the inclination angle on base end portion 311b side may be 6 degrees to 8 degrees, and the inclination angle on tip end portion 311a side may be 8 degrees to 10 degrees, forming a two-stage inclination.

[0058] (Button shaft) As shown in Figures 8 to 10, for example, the button shaft 312 has a base portion 312a provided on the underside of the upper surface portion 311 and a shaft portion 312b extending outward from the base portion 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 in a direction away from each other along the same axis. 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 axially supported on the button mounting portion 32 so as to be rotatable.

[0059] (Button side locking part) The button side locking portion 313 is a recess formed behind the button 31, as shown in Figures 9 and 10(b), 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 may 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 and may be, for example, a claw portion with which the opening / closing lid side locking portion 21 engages.

[0060] (Elastic member support part) As shown in, for example, FIGS. 8 to 10, elastic member support portions 314 are plate-shaped protrusions provided so as to protrude downward from the lower surface of upper surface portion 311, and a pair of elastic member support portions 314 are provided at a distance from each other 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 parts 314 are formed to be different sizes, with the front elastic member support part 314 being smaller than the rear elastic member support part 314, but the front elastic member support part 314 may be formed to be larger than the rear elastic member support part 314, or may be formed to be the same size.

[0061] (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 supported by being sandwiched between a pair of elastic member supporting portions 314,314. The button elastic member 33 here has a shape that is elongated 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. The button elastic member 33 is preferably arranged over approximately 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.

[0062] (Button operation) As described above, with the button locking portion 313 of the button 31 engaged with the cover locking portion 21 of the cover 2, the button 31 locks the cover 2 in the closed position. When the button 31 that engages the opening / closing lid 2 in the closed state is pressed, the button elastic member 33 elastically deforms, causing the button 31 to rotate, and the position of the button 31 is changed so that the tip end 311a side of the button 31 lowers, whereby the engagement of the opening / closing lid 2 by the button 31 is released and the opening / closing lid 2 is opened. In particular, since the button elastic member 33 is disposed over substantially the entire length of the button 31 in the left-right width direction, whether the button center portion 3a of the button portion 3 (button 31) or the button end portion 3b of the button portion 3 (button 31) is pressed, the button elastic member 33 elastically deforms appropriately, changing the position of the button 31 so that the tip portion 311a of the button 31 lowers, making it easy to open the opening / closing lid 2, which is the lid body. When 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.

[0063] When the button section 3 is operated and the cover 2 is released from its engagement with the button 31, the cover 2 is pushed up by the biasing force of the biasing member 114 and opens. In addition, the open cover 2 can be rotated in the opposite direction to when it is open, and the cover side locking portion 21 and the button side locking portion 313 can be engaged to close the cover 2.

[0064] [Effects of the embodiment] The sanitary tissue paper storage container of this embodiment is a sanitary tissue paper storage container 1 including a container body 10 in which sanitary tissue paper P is stored and which has a removal hole 113a for removing the sanitary tissue paper P, an opening / closing lid 2 which is rotatably attached to the container body 10 and which opens and closes the removal hole 113a, and a button section 3 which switches between a closed state in which the opening / closing lid 2 closes the removal hole 113a and an open state in which the opening / closing lid 2 opens the removal hole 113a. The button section 3 is a button mounting section 32 provided on the container body 10, and a button mounting section 32 which is connected to the button mounting section 32. The cover has a button 31 attached thereto and a button elastic member 33 interposed between the button 31 and the button mounting portion 32, and is configured so that when the button 31, which engages the opening / closing lid 2 in the closed state, is pressed and the button elastic member 33 is elastically deformed, the position of the button 31 is changed and the engagement of the opening / closing lid 2 is released. The button elastic member 33 is arranged to extend along the front edge of the button 31, and preferably the button elastic member 33 is arranged over approximately the entire width of the button 31.

[0065] The sanitary tissue paper storage container 1 of this embodiment has this kind of configuration, and the button elastic member 33 of the button portion 3 is arranged along the front edge of the button 31, preferably along almost the entire width of the button 31. Therefore, no matter which part of the button portion 3 (button 31) is pressed, the button elastic member 33 elastically deforms appropriately, and the position of the button 31 is changed so that the tip portion 311a of the button 31 lowers, thereby releasing the engagement of the opening / closing lid 2 by the button 31 and opening / closing lid 2. In other words, with a sanitary tissue paper storage container 1 having such a configuration, by pressing any part of the button portion 3 (button 31), the button elastic member 33 can be elastically deformed to change the position of the button 31, making it easier to release the engagement of the opening / closing lid 2 by the button 31 and open the opening / closing lid 2.

[0066] [Variations] The present invention is not limited to the above-described embodiment. For example, as shown in FIG. 11, the portions of the button elastic member 33 disposed on both sides of the button 31 in the width direction may be formed larger than the portion disposed on the center side of the button 31 in the width direction. By making both the left and right sides of the button elastic member 33 larger than other parts, the range of motion of both sides where the movement of the button 31 is difficult can be expanded, making it even easier to press the button part 3 (button 31) to open the opening / closing cover 2.

[0067] Also, as shown in FIG. 12(a), the button elastic member 33 may be disposed over approximately the entire width of the button 31 so as to follow the front edge of the tip portion 311a of the button 31, which is curved in an approximately arc shape. For example, as shown in FIG. 12(a), a pair of elastic member support parts 314, 314 may be formed to follow the front edge of the tip part 311a of the button 31, which is curved in an approximately arc shape, and the curved button elastic member 33 may be disposed between the curved elastic member support parts 314, 314, so that the curved button elastic member 33 is disposed on the underside of the button 31. This allows the button elastic member 33 to be elastically deformed more suitably regardless of which part of the button portion 3 (button 31) is pressed, making it easier to change the position of the button 31 and to open the opening / closing lid 2.

[0068] 12(b), the button elastic member 33 may be divided into a plurality of pieces and disposed. Here, four divided button elastic members 33 are disposed. By dividing the button elastic member 33 disposed on the underside of the button 31 into a plurality of parts, it becomes possible to provide button elastic members 33 having different hardness and elasticity depending on the location. For example, by making the hardness of the button elastic member 33 arranged on the end side of the button 31 lower than that on the central side, it becomes easier to switch the position of the button 31 even when pressing both side portions of the button 31, which are relatively difficult to operate. It should be noted that there is no particular limitation on the number of divided parts of the button elastic member 33. Furthermore, the divided parts of the button elastic member 33 may have the same size or different sizes. Further, in this embodiment, the button elastic member 33 arranged in a curved manner is divided into a plurality of pieces, but the button elastic member 33 arranged in a straight line may be divided into a plurality of pieces.

[0069] As described above, with the sanitary tissue paper storage container 1 of this embodiment, by pressing any part of the button portion 3 (button 31), the button elastic member 33 can be elastically deformed to change the position of the button 31, making it easy to release the engagement of the opening / closing lid 2 by the button 31 and open the opening / closing lid 2.

[0070] 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]
