     DETAILED DESCRIPTION 
     A specific embodiment of a household thin paper storing container  1  according to an embodiment of the present invention is described with reference to  FIG. 1  to  FIG. 8 . However, the technical scope of the present invention is not limited to the illustrated examples. 
     In the following, as described in the drawings, an X-axis, a Y-axis, and a Z-axis and a front-rear direction, a left-right direction, and an up-down direction are defined and described. That is, the side of the household thin paper storing container in which an open/close lid is provided is “up”, the opposite side is “down”, the side in which a container main body and the open/close lid are connected is “rear”, the opposite side is “front”, the right hand side viewed from the front side is “right”, the left hand side is “left”, 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 container main body rotates with relation to the lower container main body, the direction to which the upper container main body faces changes. Hereinbelow, as shown in  FIG. 1 , the direction is defined and described with reference to the state in which the upper container main body and the lower container main body are combined and a storage space S is closed. 
     Configuration of Embodiment 
     (Entire Configuration) 
     As shown in  FIG. 1  to  FIG. 8 , the household thin paper storing container  1  includes a container main body  10  including a take out hole  113   a  for taking out a household thin paper P stored inside, an open/close lid  2  which is connected to the container main body  10  to be opened and closed freely so as to cover the take out hole  113   a,  and a button  3  which is provided in the container main body  10  and which can be used to open and close the open/close lid  2 . The storage space S is formed to store the household thin paper P inside the household thin paper storing container  1 . 
     (Household Thin Paper) 
     For example, as the household thin paper P, a small wet sheet or wet wipe is folded and the sheets are overlapped alternately and layered. The layers are formed so that when one wet sheet or wet wipe is pulled out, the next wet sheet or wet wipe is pulled out. That is, a so-called pop-up type sheet is used. Other than the above, for example, a rolled sheet can be used. In a rolled sheet, a long wet sheet or wet wipe including perforations at a certain interval in a length direction is rolled, and the sheet is used by cutting along the perforations and separating the sheet. 
     (Container Main Body) 
     As shown in  FIG. 1  to  FIG. 7 , for example, the container main body  10  as a whole is formed in a substantial rectangular parallelepiped shape that is longer in the Y-direction than in the X-direction and the Z-direction. This is divided into two parts which are the upper part and the lower part at a position above the central portion in the Z-direction. The upper side of the container main body  10  is formed to be an upper container main body  11  and the lower side of the container main body  10  is formed to be a lower container main body  12 . The upper container main body  11  is connected to the lower container main body  12  by a connector  13  at a rear surface of the container main body  10 . 
     The upper container main body  11 , the lower container main body  12 , and the connector  13  are formed as one by a method such as injection molding (two-color molding). 
     As shown in  FIG. 1  to  FIG. 7 , the container main body  10  is formed so that in a state in which the upper container main body  11  and the lower container main body  12  are combined and the storage space S inside is closed, the size of the entire container main body  10  is, in the X-direction, preferably 60 mm to 150 mm, more preferably 80 mm to 100 mm, in the Y-direction, preferably 80 mm to 200 mm, more preferably 145 mm to 165 mm, and in the Z-direction, preferably 30 mm to 100 mm, more preferably 50 mm to 70 mm. 
     The thickness of each surface is preferably 0.5 mm to 3 mm, more preferably 1 mm to 2 mm. 
     With such size and thickness, it is possible to achieve high molding efficiency and strength that does not cause problems in actual use. 
     (Connector) 
     As shown in  FIG. 3 , the household thin paper storing container  1  is formed so as to rotate at the connector  13  as the fulcrum. The connector  13  is the connector connecting the upper container main body  11  and the lower container main body  12 . With this, as shown in  FIG. 4 , the storage space S can be in a state exposed to the outside. 
     When the storage space S is closed, the user rotates the upper container main body  11  opposite to the above. 
     As shown in  FIG. 3 , the connector  13  is formed to become thinner compared to the other portions of the household thin paper storing container  1 . With this, the connector  13  becomes easy to bend, and the upper container main body  11  can be more easily rotated with relation to the lower container main body  12  with the connector  13  as the fulcrum. 
     Although the productivity decreases, it is possible to form the upper container main body  11  and the lower container main body  12  as different bodies, and to rotatably connect the above by a hinge or the like. 
     By dividing the container main body  10  into two parts which are the upper container main body  11  and the lower container main body  12  at the position above the center portion in the Z-direction, when the stored household thin paper P is stored in the storage space S covered by a predetermined package, it is possible to decrease the possibility of pinching a seal portion at the end of the package when the storage space S is closed. With this, it becomes much easier to refill the household thin paper P. 
     The position where the container main body  10  is divided into two parts which are the upper container main body  11  and the lower container main body  12  can be near the center portion in the Z-direction. 
     (Upper Container Main Body) 
     As shown in  FIG. 2  to  FIG. 8 , the upper container main body  11  is formed to be a substantial rectangular parallelepiped shape with a substantial rectangular opening at the bottom surface. A concave portion  112  in a concave shape downward in the Z-direction is formed near the center of a top surface  111  which forms the upper surface. In the concave portion  112 , a take out portion  113  is provided including a take out hole  113   a  in the center in order to take out a household thin paper P in the storage space S. In the rear edge portion, a storing concave portion  115  is formed to store an urging member  114 . In the front edge portion, a button attaching portion  116  is formed to attach the button  3 . 
     In the lower edge of the lower surface of the upper container main body  11 , a ring shaped outer edge  117  and a ring shaped inner edge  118  which is provided to the inner side than the outer edge  117  and which projects downward than the outer edge  117  are formed. 
     In the lower edge portion of the front surface of the upper container main body  11 , a handle  119  is formed to be held when the storage space S is exposed. 
     (Material of Upper Container Main Body) 
     The upper container main body  11  is formed by a hard material which is a material that is hard. The hard material that can be used include, for example, polyethylene, polypropylene, and the like. The method for measuring the hardness is the same as described for the elastic material. 
     Preferably, the portion formed by a later described elastic material and a portion formed by a hard material are formed as one by injection molding (two-color molding). 
     (Concave Portion) 
     As shown in  FIG. 2 , the concave portion  112  is formed near the center portion of the top surface  111  in a plan view.  FIG. 2  illustrates the concave portion  112  that is shaped in a substantial curvy rectangle in a plan view and that reaches the front edge of the upper container main body  11  but the specific shape of the concave portion  112  is not limited to the above. 
     Preferably, the depth of the concave portion  112  in the Z-direction is 5 mm to 20 mm viewed from the top surface  111 . The size in the plan view is not limited if the take out portion  113  can be formed inside. Preferably, the size is 40 mm to 80 mm in the X-direction and 40 mm to 120 mm in the Y-direction. 
     (Take Out Portion) 
     The take out portion  113  is a portion which is formed near the center portion of the concave portion  112  in a plan view and which is formed of an elastic material. A substantially spherically raised bulge portion  113   b  is formed in the substantial center of the take out portion  113 , and the take out hole  113   a  is provided in the bulge portion  113   b.    
     Three projecting pieces  113   c  are provided on the edge of the take out hole  113   a  to project toward the center of the take out portion  113  from the edge of the projecting hole  113   a  on the closer side. 
     Preferably, the take out portion  113  is formed in a film shape so that the thickness in the Z-direction is 0.5 mm to 2 mm, for example. 
     The elastic material to form the take out portion  113  may be a material including elasticity, for example, silicon rubber or a thermoplastic elastomer such as styrene-butadiene type, polyester type, polyethylene type or urethane type. Preferably, the hardness is from 20 to 90. The hardness is measured by JIS K 6253 (type A durometer). 
     If the hardness of the elastic material is lower than the above value, the material is too soft and it becomes difficult to mold. This is not desirable because the molding efficiency reduces. 
     If the hardness of the elastic material becomes higher than the above value, the take out portion  113  in which the take out hole  113   a  is formed to take out the household thin paper P becomes hard and too much resistance is applied. Therefore, it becomes difficult to take out the sheet one by one. Moreover, it becomes difficult to insert the finger into the storage space S when the sheet is pulled out. In view of the above, the hardness becoming too hard is also not desirable. 
     (Take Out Hole) 
     The take out hole  113   a  is a hole which is formed in the center of the take out portion  113  in a plan view and which is connected to the storage space S. 
     For example,  FIG. 2  shows the take out hole  113   a  with a shape in which each side of a triangle is projecting in an arc shape toward the inner side. The three slits along each line connecting each vertex and the center of gravity form a substantial upside down Y shape intersecting at the center of gravity. Among the three slits, the width of the slit extending in the X-direction is wide compared to the width of the other slits. 
     The number of slits can be smaller or larger than the above number. For example, two slits in a cross shape can be formed. 
     In the take out portion  113 , the periphery of the take out hole  113   a  is formed by the elastic material and the suitable resistance can be applied to the household thin paper P. Therefore, the take out portion  113  includes the function to hold the next household thin paper P after pulling the household thin paper P stored in the storage space S. When the household thin paper P is a roll sheet, the sheet can be cut at the perforation for cutting provided in the household thin paper P. 
     (Projecting Piece) 
     The projecting piece  113   c  is provided in a position where the household thin paper P pulled out from the take out hole  113   a  slides and comes into contact in order to apply suitable resistance on the household thin paper P pulled out from the take out hole  113   a.    
     Specifically, when the user opens the open/close lid  2  of the household thin paper storing container  1  and takes out the household thin paper P, the user extends his hand from the front side of the household thin paper storing container  1  and pulls out the household thin paper P from the take out hole  113   a  so that the open/close lid  2  standing on the rear side of the household thin paper storing container  1  does not interfere with the movement of taking out the household thin paper P. With this, the household thin paper P pulled out from the take out hole  113   a  slides in contact with the projecting piece  113   c  at the edge on the closer side. 
     Here, the projecting piece  113   c  projecting to the rear from the edge on the closer side slides in contact with the household thin paper P pulled out toward the closer side from the take out hole  113   a.  With this, the projecting piece  113   c  can apply suitable resistance to the household thin paper P and this prevents the household thin paper P from being pulled out too much from the take out hole  113   a.    
     That is, the projecting piece  113   c  projecting to the rear from the closer side edge includes a function to apply suitable frictional force to the household thin paper P pulled to the closer side from the take out hole  113   a  in order to prevent the next household thin paper P pulled out after the household thin paper P to be used by being pulled out from being pulled out too much from the take out hole  113   a.    
     Then, the next household thin paper P pulled out after the household thin paper P to be used is held in the take out hole  113   a  in a state with one end pulled out at a suitable length. 
     One end of the household thin paper P held by the take out hole  113   a  is supported by the three projecting pieces including the projecting piece  113   c  on the closer side. 
     The take out hole  113   a  holding the one end of the household thin paper P is provided in the bulge portion  113   b  of the take out portion  113 . Therefore, the tip sides of the projecting pieces  113   c  are positioned higher than the take out portion  113  which is the base surface of the surrounding of the bulge portion  113   b.    
     Since the one end of the household thin paper P is held in the take out hole  113   a  supported in a position higher than the surroundings by the projecting piece  113   c,  it becomes easy to pinch the household thin paper P. 
     (Urging Member) 
     As shown in  FIG. 2 , the urging member  114  is a member in a belt shape formed of an elastic material. One end of the urging member  114  is fixed to the rear of the concave portion  112  and the other end is fixed to an insertion portion  23  (later described) of the open/close lid  2 . The urging portion urges in the direction to open and stand the open/close lid  2 . When the user presses the button  3 , the open/close lid  2  is moved so as to rotate at the connecting portion at the rear of the upper container main body  11  as the rotating axis. With this, the open/close lid  2  opens. 
     The urging member  114  is formed in a belt shape with a width preferably 2 mm to 30 mm, more preferably 8 mm to 10 mm, and a thickness preferably 0.5 mm to 3 mm, more preferably 1 mm to 2 mm. 
     By forming the urging member  114  to be such size, the open/close lid  2  can be pressed up without difficulty when opened, and when the open/close lid  2  is closed, the urging member can be easily folded and stored in the storing concave portion  115 . 
     The urging member  114  is formed to extend as shown in  FIG. 2  in a state in which no force is applied. Therefore, when the open/close lid  2  is closed as shown in  FIG. 7  and the urging member  114  is folded, the force to return to the state shown in  FIG. 2  is generated. With this, it is possible to urge the open/close lid  2  to rotate backward with relation to the upper container main body  11  at the connector  13  as the rotating axis. The connector  13  is the connector between the rear of the open/close lid  2  and the upper container main body  11 . 
     (Storing Concave Portion) 
     As shown in  FIG. 7 , the storing concave portion  115  is a concave portion to store the folded portion of the urging member  114  when the open/close lid  2  is closed and the urging member  114  is pressed downward. 
     As shown in  FIG. 2 , the storing concave portion  115  is formed to be a concave shape in a position to the rear of the take out portion  113  in the concave portion  112  and near the front of the urging member  114  so as to be downward in the Z-direction than the concave portion  112 . 
     The shape of the storing concave portion  115  is not limited, and for example, the shape is a substantial rectangular parallelepiped shape long in the Y-direction compared to the X-direction. The storing concave portion  115  is to include a space to be able to store the folded urging member  114  pressed by the open/close lid  2  when the open/close lid  2  is closed. 
     (Button Attaching Portion) 
     The button attaching portion  116  is formed of a hard material in the front edge of the concave portion  112 . The button attaching portion  116  includes a main body side fitter  1161  formed in a ring shape to be a convex shape upward in the Z-direction and a button movable portion  1162  which is formed in a concave shape downward in the Z-direction so as to surround the left/right portion and the front portion of the main body side fitter  1161  in a plan view. 
     (Main Body Side Fitter) 
     For example, the main body side fitter  1161  is formed so that the front side is a curved shape in a plan view and the rear side is in a straight line shape in a plan view. The inner circumference of the main body side fitter  1161  is formed to be slightly larger than the outer circumference of a button side fitter  32  (later described) formed in the button  3 . The main body side fitter  1161  is formed so that the button  3  can be attached to the button attaching portion  116  by inserting the button side fitter  32  from the above. 
     (Button Movable Portion) 
     The button movable portion  1162  is formed to be a concave shape downward to surround the left/right portion and the front portion of the main body side fitter  1161 . The button movable portion  1162  is formed of the elastic material similar to the take out portion  113 . With this, the button movable portion  1162  is formed so that when a front end  31   a  of the button is inserted in the main body side fitter  1161  and pressed from the above, the button movable portion  1162  elastically deforms so that the button  3  tilts downward. 
     (Outer Edge/Inner Edge) 
     The outer edge  117  is a ring shape as shown in  FIG. 4  and  FIG. 5 , and is formed in the lower edge of the upper container main body  11 . 
     The inner edge  118  is a ring shape as shown in  FIG. 4  and  FIG. 5 . The inner edge  118  is provided to the inner side than the outer edge  117  in the lower edge of the upper container main body  11  and projects downward than the outer edge  117 . The inner edge  118  is formed so that the inner edge  118  enters a later-described concave groove  121  of the lower container main body  12  when the storage space S is closed. 
     (Handle) 
     For example, as described from  FIG. 1  to  FIG. 8 , the handle  119  is formed projecting in an arch shape from the front surface as one with the upper container main body  11  in the center of the front surface of the upper container main body  11  and a space a is formed between the handle  119  and the front surface to be able to hook the finger. Two latches  1191  are provided on the inner surface of the handle portion  119  facing the front surface. When the storage space S is exposed, the handle  119  is held, and the upper container main body  11  is rotated with the connector  13  as the fulcrum. 
     As described in  FIG. 7  and  FIG. 8 , the portion where the front surface of the upper container main body  11  intersects with the inner surface of the handle  119  is an R shape, and is formed to be round. 
     The shape of the handle  119  may be any shape. The shape of the handle  119  does not have to be a shape projected in an arch shape and is to be a shape which projects from the front surface of the upper container main body  11  and which includes a space a between the front surface. 
     The handle  119  overlaps in the front-rear direction with an engaging protrusion  123  (later-described) provided in the lower container main body  12  in the state in which the upper container main body  11  is engaged with the lower container main body  12 . According to the above, the engaging protrusion  123  cannot be seen from the front. 
     (Latch) 
     As described in  FIG. 4  to  FIG. 8 , two latches  1191  are provided with a predetermined interval along the left-right direction on the inner surface of the handle  119 . The latches  1191  are formed to engage to the engaging protrusion  123  when the storage space S is closed so that the closed state is maintained. 
     The interval provided between the two latches  1191  may be determined freely, but is preferably larger than a width of a finger of a typical user. Specifically, the latches  1191  are formed to be separated 5 mm to 25 mm, more preferably 18 mm to 25 mm. 
     The number of latches  1191  is not limited to two, and is to be provided in each position separated to the left and right from the center portion of the inner surface of the handle  119  in the left-right direction. For example, two in the left and two in the right (a total of four) may be provided. 
     (Lower Container Main Body) 
     As shown in  FIG. 4 , the lower container main body  12  is formed in a substantial rectangular parallelepiped shape with an opening in a substantial rectangular shape in the upper surface. A ring shaped concave groove  121  is formed in an upper edge of the lower container main body  12 . 
     A slipping preventer  122  is formed in the base of the upper surface of the lower container main body  12  in order to prevent slipping when the household thin paper P stored in the storage space S is pulled out from the take out hole  113   a.    
     The engaging protrusion  123  is formed as one with the lower container main body  12  near the center of the upper edge of the front surface of the lower container main body  12  so as to project in the front direction. 
     (Material of Lower Container Main Body) 
     The lower container main body  12  is formed of the hard material similar to the material used in the upper container main body  11 . 
     (Concave Groove) 
     The concave groove  121  is a ring shape as shown in  FIG. 4  and is formed in the upper edge of the lower container main body  12  so that the inner edge  118  of the upper container main body  11  engages when the storage space S is closed. The concave groove  121  includes an outer peripheral wall  1211  and an inner peripheral wall  1212 . 
     (Outer Peripheral Wall and Inner Peripheral Wall) 
     The outer peripheral wall  1211  is formed as the outer peripheral wall surface of the lower container main body  12  and the outer peripheral wall  1211  comes into contact with the outer edge  117  of the upper container main body  11  when the storage space S is closed. 
     The inner peripheral wall  1212  is formed as the inner peripheral wall surface of the lower container main body  12 . As shown in  FIG. 4 , the inner peripheral wall  1212  is provided with first guides  1212   a  provided at both ends of the rear surface in the left-right direction, and a plurality of second guides  1212   b  provided in the left-right direction of the rear surface. The first guide  1212   a  and the second guide  1212   b  project upward than the outer peripheral wall  1211 . 
     The inner edge  118  of the upper container main body  11  slides between the outer peripheral wall  1211  and the inner peripheral wall  1212  so as to maintain airtightness of the storage space S. 
     (First and Second Guides) 
     For example, the first guide  1212   a  is provided in both of the left and right edges on the rear surface of the lower container main body  12  extending the left surface and the right surface. The height of the first guide  1212   a  is higher than the height of the outer peripheral wall  1211  and the second guide  1212   b  in the Z-direction. 
     The second guides  1212   b  are a wave shape, and a plurality of second guides  1212   b  are provided along the left-right direction in the rear surface of the lower container main body  12 . The height of the second guide  1212   b  is higher than the height of the outer peripheral wall  1211  in the Z-direction but lower than the height of the first guide  1212   a  in the Z-direction. 
     (Slipping Preventer) 
     The slipping preventer  122  is formed of the elastic material surrounded by the hard material in the base of the lower container main body  12 . For example, as shown in  FIG. 4 , the slipping preventer  122  includes a shape in an arc in two angles formed extending in the Y-direction among the angles formed by two straight lines which connect the opposing vertices of the rectangle and which intersect at the center of gravity. 
     The four ends of the above two straight lines are round, and as shown in  FIG. 6 , the elastic material comes into contact with the placing surface only in the round portion. This functions as a placing portion  1221 . 
     (Engaging Protrusion) 
     As shown in  FIG. 4  and  FIG. 5 , the engaging protrusion  123  is a protrusion projecting in the front direction formed as one with the lower container main body  12  in the substantial center of the upper edge of the front surface of the lower container main body  12 . The two latches  1191  are engaged when the storage space S is closed. 
     The engaging protrusion  123  is formed so that the length in the Y-direction is longer than the sum of the interval between the two latches  1191  and the lengths of the two latches  1191  in the Y-direction. 
     (Open/Close Lid) 
     As shown in  FIG. 1  to  FIG. 3 , the open/close lid  2  is a flat and curved member in a substantial rectangular shape rotatably connected to the rear of the concave portion  112 . The open/close lid  2  includes an open/close lid side latch  21  on the front side in the closed state, an open/close lid side sealing ring  22  on the lower surface side, and an insertion portion  23  in which the urging member  114  is inserted. 
     The shape of the open/close lid  2  in a plan view when closed is formed to be substantially the same shape as the concave portion  112  of the upper container main body  11  in a plan view with the exception of the shape of the portion where the button  3  is provided. The open/close lid  2  is formed so that it is possible to be fitted in the concave portion  112  and to be on the same plane as the top surface  111  when the open/close lid  2  is closed. 
     (Material of Open/Close Lid) 
     As shown in  FIG. 1  to  FIG. 3 , the open/close lid  2  is formed entirely of the hard material the same as the material used in the container main body  10 . 
     (Open/Close Lid Side Latch) 
     For example, as shown in  FIG. 2  and  FIG. 3 , the open/close lid side latch  21  is a portion of the open/close lid  2  in a claw shape projecting to the front. The open/close lid side latch  21  engages with a button side latch  33  formed in the button  3 . With this, the portions are latched when the open/close lid  2  is closed. The open/close lid side latch  21  is formed so that when the user presses the button  3 , and the link between the open/close lid side latch  21  and the button side latch  33  is released, the open/close lid  2  is opened by the urging force caused by the urging member  114 . 
     The shape of the open/close lid side latch  21  may be any shape which engages to the button side latch  33  to be latched when the open/close lid  2  is closed, and in which the link between the open/close lid side latch  21  and the button side latch  33  is released when the user presses the button  3 . The shape is not limited to the claw shape as shown in  FIG. 2  and  FIG. 3 . 
     (Open/Close Lid Side Sealing Ring) 
     As shown in  FIG. 2 , the open/close lid side sealing ring  22  is formed to project in a ring shape downward when the open/close lid  2  is closed. As shown in  FIG. 7 , the open/close lid side sealing ring  22  is formed in the substantial center of the lower surface side so that the surface on the inner peripheral side comes into contact with the outer peripheral of the take out portion  113  formed in the upper container main body  11 . 
     (Insertion Portion) 
     As shown in  FIG. 2 , the insertion portion  23  is a portion in which the urging member  114  is inserted to be fixed in the rear edge of the open/close lid  2 . 
     (Button) 
     The button  3  includes an upper surface  31  which forms the upper surface, a button side fitter  32  which projects downward from the upper surface  31 , and a button side latch  33  which engages to the open/close lid side latch  21 . The button  3  is formed so that, by inserting the open/close lid side latch  21  in the button side latch  33 , the open/close lid  2  is latched in the closed state. The button  3  is formed so that when the user presses the button  3 , the latch with the open/close lid side latch  21  is released, and the open/close lid  2  is opened. 
     The button  3  is formed of the hard material which is the same as the material used in the container main body  10 . The button  3  is formed independently as a different member. Then, the button  3  is fixed by the button attaching portion  116 . 
     Preferably, the household thin paper storing container  1  is formed entirely as one by injection molding (two color molding) with the exception of the open/close lid  2  and the button  3  as described above. 
     (Upper Surface) 
     As shown in  FIG. 1 ,  FIG. 7 , and  FIG. 8 , the upper surface  31  is a portion forming the upper surface of the button  3 . For example, the upper surface  31  is formed so that the rear side is a straight line and the front side is a curve in a plan view. The upper surface  31  is formed to be substantially the same shape as the shape near the front edge of the concave portion  112  in a plan view with the exception of near the front end  31   a.  The front end  31   a  is formed to project forward from the concave portion  112 . 
     The size of the upper surface  31  is determined according to the size of the portion which is not covered by the open/close lid  2  in the concave portion  112 . Preferably, the size is 10 mm to 30 mm in the longest portion in the X-direction and 30 mm to 100 mm in the longest portion in the Y-direction. 
     A space b is formed between the front end  31   a  of the upper surface  31  and the upper container main body  11 , and the front end  31   a  and a base end  31   b  are formed to tilt downward in different angles from the upper surface (horizontal) of the upper container main body  11 . 
     Here, an inclined angle of the front end  31   a  is formed to be larger than the inclined angle of the base end  31   b.  Specifically, preferably, the inclined angle of the base end  31   b  is 6 to 8 degrees and the inclined angle of the front end  31   a  is 8 to 10 degrees. 
     The base end  31   b  of the button is parallel with relation to the upper container main body  11 , and only the front end  31   a  may be tilted downward or the tilt may be the same angle from the base end  31   b  to the front end  31   a.    
     (Button Side Fitter) 
     For example, the button side fitter  32  is formed to project downward from the upper surface  31  in a ring shape with the front side in a curved shape and the rear side in a straight line shape from a base view. The outer circumference is formed to be slightly smaller than the inner circumference of the main body side fitter  1161 . The button side fitter  32  is formed to be inserted in the main body side fitter  1161  from above so as to be able to attach the button  3  to the button attaching portion  116 . 
     The inner circumference may be formed to be the same or slightly larger than the outer circumference of the above described main body side fitter  1161 . The button side fitter  32  may be formed to insert the main body side fitter  1161  from below so as to be able to attach the button  3  to the button attaching portion  116 . 
     (Button Side Latch) 
     The button side latch  33  is a hole formed in the rear of the button  3 . The open/close lid side latch  21  formed in the open/close lid  2  is inserted inside the button side latch  33  and linked. With this, the open/close lid  2  is latched in the closed state. The button side latch  33  is formed so that when the user presses the button  3 , the insertion of the open/close lid side latch  21  is released, and due to the urging force caused by the urging member  114 , the open/close lid  2  is opened. 
     The shape of the button side latch  33  can be any shape as long as the button side latch  33  latches the open/close lid  2  in the closed state and the link between the button side latch  33  and the open/close lid side latch  21  is released when the user presses the button  3 . The shape is not limited to a hole as illustrated above, and may be a claw to where the open/close side latch  21  links, for example. 
     Effects of Embodiments 
     The main effects obtained from the above embodiment is described. 
     (Close of Container) 
     According to the present embodiment, in the household thin paper storing container  1 , when the storage space S is closed, the inner edge  118  of the upper container main body  11  is fitted in the concave groove  121  of the lower container main body  12 . Therefore, even if pressure is applied to the household thin paper storing container  1  in the X-direction and the Y-direction, the storage space S is not easily exposed, the close of the storage space S is maintained, and the sealing is good. 
     When the storage space S is closed, the inner edge  118  of the upper container main body  11  hits the first guide  1212   a  and the second guide  1212   b  provided in the lower container main body  12 , and is guided to the concave groove  121 . Therefore, the storage space S can be closed more reliably. 
     Since the height of the two first guides  1212   a  are higher than the height of the second guides  1212   b  in the Z-direction, when the storage space S is closed, even if the upper container main body  11  is slightly twisted with relation to the lower container main body  12 , the higher first guide  1212   a  functions as a guide and makes a correction. Therefore, the storage space S can be closed more reliably. 
     Further, the two first guides  1212   a  are provided in both of the left and right ends of the rear surface by extending the left surface and the right surface. With this, the above-described effect is further enhanced. 
     The second guide  1212   b  is provided in a wave form. Therefore, compared to providing the second guide  1212   b  throughout the entire left-right direction, the resistance due to contact can be decreased. Consequently, the open/close movement can be performed more smoothly. 
     (Entire Configuration) 
     The container main body  10  includes the upper container main body  11  and the lower container main body  12  and the above are connected by a connector  13  at the rear surface. Therefore, while placing the household thin paper storing container  1  on the placing surface, the storage space S can be exposed by rotating the upper container main body  11  with the rear edge as the fulcrum and the household thin paper P can be refilled. 
     Therefore, when the household thin paper P is refilled, the container remains to be placed on the placing surface and the operation of refilling can be easily performed. 
     (Button, Etc.) 
     The button  3  is provided in the household thin paper storing container  1 , the inclination angle of the front end  31   a  is formed to be larger than the inclination angle of the base end  31 b. Therefore, it is difficult to insert the finger in the space b between the button  3  and the upper container main body  11 . Consequently, when the household thin paper P is refilled, it is possible to prevent mistakenly holding the button  3  instead of the handle  119  and trying to rotate it. 
     The button  3  is attached to the main body side fitter  1161  surrounded by the button movable portion  1162  projecting downward. With this, when the user presses the upper surface  31  of the button  3  from above when the open/close lid  2  is closed, regardless of the pressed position, the button movable portion  1162  is lowered downward and the button  3  sinks downward. 
     Here, since the open/close lid side latch  21  of the open/close lid  2  is inserted in the button side latch  33  of the button  3 , when the button  3  sinks downward, the open/close lid  2  is also pushed downward. However, the open/close lid  2  is urged upward by the urging member  114 , and such urging force becomes stronger as the open/close lid  2  sinks more downward. 
     Therefore, when the button  3  is pressed to a certain degree, the open/close lid  2  also sinks, and the urging force that urges the open/close lid  2  upward becomes stronger. The open/close lid  2  and the button  3  are engaged only by the open/close lid side latch  21  and the button side latch  33 . Therefore, if the urging force to the open/close lid  2  becomes strong, the link is released and the open/close lid  2  is opened. 
     Therefore, according to the present embodiment, the open/close lid  2  can be easily opened by pressing any portion of the upper surface of the button  3 . 
     The upper container main body  11  includes the button attaching portion  116  including the main body side fitter  1161 . Therefore, the button  3  can be fixed easily and stably. 
     (Handle) 
     The handle  119  is provided in the upper container main body  11 , and the inner circumference side of the handle  119  is formed to be a curved surface by R processing. Compared to when the inner circumference side is a sharp angle, the handle  119  can be spread to the outer side easily, and the link between the latch  1191  and the engaging protrusion  123  can be easily released. With this, the storage space S can be easily exposed. 
     When the upper container main body  11  is engaged with the lower container main body, the handle  119  overlaps with the engaging projection  123  provided in the lower container main body  12  in a front-rear direction. With this, the engaging protrusion  123  cannot be viewed from the front, and this makes the look good. 
     The latch  1191  is provided in the handle  119 . Therefore, the user is able to easily release the link between the upper container main body  11  and the lower container main body  12  by hooking the finger in the space a between the front surface of the upper container main body  11  and the handle  119 . With this, the storage space S can be exposed. 
     Specifically, a plurality of latches  1191  are provided in each position separated to the left and right from the center portion in the left-right direction on the inner surface of the handle  119 . Therefore, when the finger is inserted near the center of the handle  119 , the latch  1191  does not interfere, and the link between the upper container main body  11  and the lower container main body  12  can be easily released. With this, the storage space S can be easily exposed. 
     Two latches  1191  are formed on the inner surface of the handle  119 , and the interval between the two latches  1191  is to be wider than the finger width. Therefore, when the upper container main body  11  is rotated, the finger easily enters between the two latches  1191  and the upper container main body  11  is easily rotated. With this, the storage space S can be easily exposed. 
     The length of the engaging protrusion  123  in the left-right direction is longer than the length obtained by adding the length of the two latches  1191  in the left-right direction and the distance between the two latches  1191 . The two latches  1191  are engaged to the one engaging protrusion  123 . Therefore, the strength is enhanced than providing the engaging protrusion  123  separately for each latch  1191 . With this, a more stable link with the latch  1191  can be achieved. 
     The upper container main body  11 , the lower container main body  12 , and the connector  13  are formed as one by an injection molding method (two-color molding). Therefore, the method is excellent from the view point of efficiency of manufacturing the household thin paper storing container  1 . 
     (Take Out Hole) 
     The next household thin paper P pulled out from the take out hole  113   a  is held in the take out hole  113   a  in a state with one end pulled out in a suitable length. Therefore, the household thin paper P held in the take out hole  113   a  does not interfere when the open/close lid  2  is closed. 
     Since the household thin paper P held in the take out hole  113   a  is not pinched by the open/close lid  2 , trouble such as the wet household thin paper P (wet wipes, etc.) being pinched by the open/close lid  2  and extending outside of the container main body  10 , and then drying does not occur. 
     According to the household thin paper storing container  1  provided with the take out hole  113   a,  the household thin paper P can be suitably pulled out and used. Following the household thin paper P that is pulled out and used, one end of the household thin paper P pulled out next can be held in the take out hole  113   a  without interfering with the closing of the open/close lid  2 . 
     Then, since the household thin paper P with a suitable length pulled out is held in the take out hole  113   a,  the household thin paper P stored in the storage space S can be suitably pulled out and used repeatedly. 
     Only the width of the slit extending in the X-direction among the three slits of the take out hole  113   a  is wider compared to the width of the other slits. Therefore, the location where the one end of the household thin paper P held in the take out hole  113   a  is supported by the two projecting pieces  113   c  other than the one in the closer side is dispersed. With this, the one end of the household thin paper P can be supported more stably in the take out hole  113   a.    
     The other two slits extending to the closer side have widths that are relatively narrow. Therefore, it is possible to prevent one end entering the slit when the household thin paper P is taken out. 
     (Urging Member) 
     According to the household thin paper storing container  1  of the present embodiment, the open/close lid  2  can be urged in the opening direction by only providing the urging member  114  formed by the elastic material in the upper container main body  11 . 
     On the other hand, for example, if a spring shaped urging member is provided standing upward, and this is connected to the open/close lid  2 , the bending and extending are repeated each time the open/close lid  2  is opened and closed. As a result, such spring portion easily deteriorates, and the urging force to the open/close lid  2  tends to weaken quickly. When the urging force to the open/close lid  2  weakens to a certain degree, it is not possible to open the open/close lid  2  by only one movement. 
     According to the present embodiment, the urging member  114  formed of the elastic material is pressed by the open/close lid  2  and the urging force to the open/close lid  2  is generated. Therefore, the deformed amount of the portion formed of the elastic material is small and hardly deteriorates. Therefore, it becomes difficult for the urging force on the open/close lid  2  to weaken. 
     Since the storing concave portion  115  is provided in the concave portion  112 , it is possible to prevent the pressure on the portion of the urging member  114  in contact with the concave portion  112  to become too large. Therefore, it is possible to reduce the possibility that the urging member  114  breaks. 
     The urging member  114  is formed on the rear side of the container main body  10 , close to the fulcrum of the rotation of the open/close lid  2 . Therefore, the urging force on the open/close lid  2  is strengthened and it becomes easy to open. 
     (Other Configurations) 
     The slipping preventer  122  is provided on the upper surface of the lower container main body  12 . When the household thin paper P is taken out from the take out hole  113   a,  it is difficult for the household thin paper P in the storage S to move and it is less likely to collapse. Therefore, the household thin paper P can be stably taken out. 
     A portion forming the slipping preventer  122  comes into contact with the placing surface and functions as the placing portion  1221 . Therefore, when the household thin paper storing container  1  is placed on the placing surface, the stability is enhanced. 
     When the open/close lid  2  is closed, the open/close lid side sealing ring  22  comes into contact with the outer circumference of the take out portion  113 . Therefore, the sealing properties of the storage space S can be enhanced. 
     [Modification] 
     The modification of the above embodiment is described below. 
     (Handle) 
     The handle  119  may be formed as one with another portion of the upper container main body  11 , or may be a separate portion attached later. 
     (Engaging Protrusion) 
     The engaging protrusion  123  does not have to be one and two may be provided so as to correspond to each of the two latches  1191 . 
     (Guide) 
     The guide may only include the first guide  1212   a  or may only include the second guide  1212   b.    
     The first guide  1212   a  does not have to be provided by extending the left surface or the right surface. 
     The second guide  1212   b  does not have to be a wave shape and may be provided with the same height throughout the left-right direction. 
     (Button) 
     The button  3  is to be provided in the upper container main body  11  to be able to move up and down by the button movable portion  1162 . The button  3  does not have to be attached by the button attaching portion  116 . For example, the button movable portion  1162 A can be made of the elastic material and be provided throughout the entire lower side of the button  3 . Then, the button  3  can be directly attached to the button movable portion  1162 A by adhesion, etc. 
     (Connector) 
     The connector  13  described above is described to be formed only in one position near the center of the household thin paper storing container  1  in the left-right direction. However, the configuration of the connector  13  is not limited to the above. 
     For example, the connector may be the connectors  13 A,  13 A formed in the left and right of the household thin paper storing container  1 A. In this case, when the storage space SA is exposed, it becomes difficult for the connector  13 A to twist and the stability is enhanced. Moreover, the motion to close the storage space SA again becomes easy to perform. 
     Alternatively, a connector  13 B which covers the entire rear surface side of the household thin paper storing container  1 B can be used. In this case, when the storage space S is closed, the entire rear surface side of the portion in contact between the upper container main body  11  and the lower container main body  12  of the household thin paper storing container  1 B is covered. Therefore, the sealing properties of the storage space S can be further enhanced. 
     In addition, the configuration of the details of the household thin paper storing container  1  may be suitably changed without leaving the scope of the present invention. 
     The present invention can be used in a household thin paper storing container in which the household thin paper inside can be easily refilled.
