  • the main body 10 is obtained from one sheet 70.
  • the insertion portion 72 may or may not be glued to the inner surface of each portion 14p, 18p, and 19p. In the former case, it is necessary to place the sanitary paper 90 in the above space prior to gluing. In the latter case, the main body 10 having the main surface 12 that can be opened and closed is obtained.
  • the sanitary paper storage box 1 has a folding piece 22 that can be folded diagonally upward from the main surface 12. By folding the folding piece 22, an opening 60 that forms the removal port can be created in the main surface 12. At this time, the folding piece 22 is folded along the fold line 32, which has a curved shape that bulges outward from the folding piece 22. In this case, unlike when the folding piece 22 is folded along the fold line 32, a force (return force) that tries to return the folding piece 22 to its original state (unfolded state) acts on the folding piece 22 that is folded along the fold line 32. For this reason, it is possible to prevent the folding angle of the folding piece 22 from becoming too large. Therefore, a sanitary paper storage box 1 that can suppress the intrusion of dust into the main body 10 through the removal port is realized.
  • the fold 34 also has a curved shape that bulges outward from the folding piece 24.
  • a restoring force also acts on the folding piece 24 that is folded along the fold 34. This makes it possible to prevent the folding angle of the folding piece 24 from becoming too large. This further prevents dust from entering the main body 10 through the removal opening.
  • the mechanism by which the curved fold line 32 regulates the bending angle of the folding piece 22 will now be elaborated upon. If the main body 10 is rigid (not flexible), the folding piece 22 cannot be bent along a curve. In contrast, in the sanitary paper storage box 1, the main body 10 is flexible, so even if the fold line 32 is curved, the bending of the main body 10 makes it possible to bend the folding piece 22 to a certain degree of angle. At this time, a return force acts on the folding piece 22 due to the restoring force of the main body 10. This regulates the bending angle of the folding piece 22. The same applies to the mechanism by which the curved fold line 34 regulates the bending angle of the folding piece 24.
  • the fold line 32 forms a circular or elliptical arc
  • it contributes to improving the aesthetic appearance of the fold line 32 and therefore the sanitary paper storage box 1.
  • the fold line 34 forms a circular or elliptical arc, it contributes to improving the aesthetic appearance of the fold line 34 and therefore the sanitary paper storage box 1.
  • Increasing the curve rate of the fold line 32 is advantageous in strengthening the return force acting on the folding piece 22. From this perspective, it is preferable that the curve rate of the fold line 32 is 1.9% or more. On the other hand, if the curve rate of the fold line 32 is too large, the return force will be excessively strong, which may make it difficult to remove the sanitary paper 90 from the main body 10. From this perspective, it is preferable that the curve rate of the fold line 32 is 9.7% or less, and more preferably 4.8% or less.
  • Increasing the curve rate of the fold line 34 is advantageous in strengthening the return force acting on the folding piece 24. From this perspective, it is preferable that the curve rate of the fold line 34 is 1.9% or more. On the other hand, if the curve rate of the fold line 34 is too large, the return force will be excessively strong, which may make it difficult to remove the sanitary paper 90 from the main body 10. From this perspective, it is preferable that the curve rate of the fold line 34 is 9.7% or less, and more preferably 4.8% or less.
  • the tip edge 22a of the folded piece 22 is wavy. In this case, the tip edge 22a has unevenness. This allows the holding force of the folded piece 22 against the sanitary paper 90 to be strengthened.
  • the tip edge 24a of the folded piece 24 is wavy. In this case, the tip edge 24a has unevenness. This allows the holding force of the folded piece 24 against the sanitary paper 90 to be strengthened.
  • the leading edge 22a of the folded piece 22 has a shape without corners. This makes it difficult for the sanitary paper 90 to get caught on the leading edge 22a when removing the paper, making it easier to remove the sanitary paper 90 smoothly.
  • the leading edge 24a of the folded piece 24 has a shape without corners. This makes it difficult for the sanitary paper 90 to get caught on the leading edge 24a when removing the paper, making it easier to remove the sanitary paper 90 smoothly.

  • the tip edge 24a of the folded piece 24 describes a sine curve. This contributes to improving the aesthetics of the folded piece 24 and therefore the sanitary paper storage box 1.
  • the half wavelength of the leading edge 22a of the folded piece 22 is advantageous in strengthening the holding power of the folded piece 22 to the sanitary paper 90, since the unevenness of the leading edge 22a becomes finer. From this perspective, the half wavelength of the leading edge 22a is preferably 10 mm or less, and more preferably 5 mm or less. On the other hand, if the half wavelength of the leading edge 22a is too small, the sanitary paper 90 will easily get caught on the leading edge 22a. From this perspective, the half wavelength of the leading edge 22a is preferably 3 mm or more.
  • the half wavelength of the leading edge 24a of the folded piece 24 is advantageous in strengthening the holding power of the folded piece 24 against the sanitary paper 90, since the unevenness of the leading edge 24a becomes finer.

On the other hand, if the half wavelength of the leading edge 24a is too small, the sanitary paper 90 will easily get caught on the leading edge 24a. From this perspective, the half wavelength of the leading edge 24a is preferably 3 mm or more.
  • the total amplitude of the tip edge 22a of the folded piece 22 increases the unevenness of the tip edge 22a, which is advantageous in strengthening the holding power of the folded piece 22 against the sanitary paper 90. From this perspective, it is preferable that the total amplitude of the tip edge 22a is 3 mm or more. On the other hand, if the total amplitude of the tip edge 22a is too large, the sanitary paper 90 will penetrate too deeply into the recess, preventing smooth removal of the sanitary paper 90. From this perspective, it is preferable that the total amplitude of the tip edge 22a is 10 mm or less, and more preferably 5 mm or less.

  • the main body 10 has a cutting blade 52. This makes it easier to cut the sanitary paper 90 neatly compared to cutting the sanitary paper 90 pulled out of the main body 10 by hand.
  • the cutting blade 52 is located at a position separated from the folded piece 22 (and folded piece 24). In this case, after cutting, the sanitary paper 90 pulled out of the main body 10 remains between the folded piece 22 and the cutting blade 52. This has the advantage that the sanitary paper 90 can be easily picked up the next time it is pulled out.
  • the cutting blade 52 is provided on the periphery of the main surface 12. In this case, by connecting the cutting blade 52 to the side of the main body 10, the main body 10 having the cutting blade 52 can be realized with a simple configuration. In fact, in the sanitary paper storage box 1, the cutting blade 52 is connected to the upper end of the side surface 18.
  • the main body 10 has insertion sections 54, 56. This makes it difficult for the central axis of the sanitary paper 90 to wobble. This is advantageous for stably pulling out the sanitary paper 90 from the main body 10.
  • the insertion portion 54 is made of a part of the side surface 14 of the main body 10. This allows the main body 10 having the insertion portion 54 to be realized with a simple configuration.
  • the insertion portion 56 is made of a part of the side surface 16 of the main body 10. This allows the main body 10 having the insertion portion 56 to be realized with a simple configuration.
  • each insertion portion 54, 56 is a regular n-sided polygon (n is an integer of 5 or more), the outer shape is close to a circle. This makes it easier to smoothly rotate the sanitary paper 90 with the insertion portion 54, 56 inserted in the center.
  • the outer surface of the main body 10 can be used as a canvas for drawing. Also, if a line drawing is printed on the outer surface of the main body 10 in advance, the user can enjoy coloring in it. In other words, a line drawing for coloring may be printed on the outer surface of the main body 10. For this reason, the sanitary paper storage box 1 is also suitable as a toy for children.
  • the entire body 10, including the cutting blade 52, the insertion portion 54, and the insertion portion 56, are made of the same material. This helps reduce the manufacturing costs of the sanitary paper storage box 1.
  • the main body 10 is configured to be refilled with sanitary paper 90, the main body 10 can be reused by refilling it with new sanitary paper 90 even after the sanitary paper 90 has been used up, which is economical. This also leads to a reduction in waste (unnecessary main bodies 10), thereby contributing to a reduction in the burden on the environment.
  • the sanitary paper storage box 1 does not have a plastic film at the outlet. This also leads to a reduction in waste (unnecessary plastic), which contributes to reducing the burden on the environment.
  • the present invention is not limited to the above embodiment, and various modifications are possible.
  • the entire main body 10 is made of a single material.
  • the main body 10 may be made of multiple materials.
  • plastic or metal as the material for the cutting blade 52
  • cardboard as the material for the remainder of the main body 10 (portions other than the cutting blade 52).
  • cardboard as the material for the main surface 12, while using another material as the material for the remainder of the main body 10 (portions other than the main surface 12).
  • other materials include cardboard, CNF (cellulose nanofiber), wood, plastic, or metal.
  • each insertion portion 54, 56 is an n-sided polygon (n is an integer of 5 or more).
  • the outer shape of each insertion portion 54, 56 may be a triangle or a rectangle. In that case, while it becomes more difficult for the sanitary paper 90 to rotate smoothly, it becomes more difficult for the sanitary paper 90 to rotate in the reverse direction. This has the advantage that the sanitary paper 90 pulled out of the main body 10 is less likely to go back in.
  • the main body 10 may be provided with only either the insertion portion 54 or the insertion portion 56. Alternatively, the main body 10 may not be provided with either the insertion portion 54 or the insertion portion 56.
  • the cutting blade 52 protrudes above the main surface 12.
  • the cutting blade 52 may protrude to the side of the main surface 12, as shown in FIG. 15, for example.
  • the cutting blade 52 can be formed integrally with the main surface 12.
  • the case where the cutting blade 52 is provided on the main body 10 is exemplified.
  • the main body 10 does not have to be provided with a cutting blade 52.
  • the sanitary paper 90 pulled out from the main body 10 may be cut by hand or by the leading edge 22a of the folded piece 22 or the leading edge 24a of the folded piece 24.
  • the cut line 42 is wavy.
  • the cut line 42 may be curved and bulged toward the folded piece 22 or the folded piece 24, as shown in FIG. 16.
  • the cut line 42 is curved and bulged toward the folded piece 22.
  • the curve rate of the cut line 42 is equal to the curve rate of each fold 32, 34.
  • the leading edge 22a of the folding piece 22 is concave and the leading edge 24a of the folding piece 24 is convex.
  • the leading edge 22a is concave in this way, the sanitary paper 90 is more likely to wrinkle when it passes near the leading edge 22a.
  • the sanitary paper 90 spreads in the vertical direction of the main surface 12, making it easier for the sanitary paper 90 to remain sandwiched between the folding pieces 22 and 24. This makes it less likely for the sanitary paper 90 pulled out of the outlet to fall into the main body 10.
  • the leading edge 24a of the folding piece 24 is convex, the leading edge 24a is more likely to come into contact with the sanitary paper 90.
  • the curve rate of the cut line 42 may be greater or smaller than the curve rate of each crease 32, 34.
  • the cut line 42 may be a straight line, as shown in FIG. 17, for example. In that case, it becomes easier to make cuts along the cut line 42.
  • the cut line 42 is made up of a single line.
  • the cut line 42 may be made up of multiple lines, as shown in FIG. 18, for example.
  • the cut line 42 is made up of cut line 42a and cut line 42b.
  • the cut line 42a has multiple convex portions that protrude toward the cut line 42b side.
  • Each of the convex portions that make up the cut line 42a is a round convex portion with a rounded tip.
  • the cut line 42b has multiple convex portions that protrude toward the cut line 42a side.
  • Each of the convex portions that make up the cut line 42b is also a round convex portion.
  • cut lines 42 cut lines 42a, 42b), 44, and 46
  • the portion between cut lines 42a and 42b is cut out from main surface 12. Therefore, even when folding pieces 22 and 24 are not folded, a gap is created between them. This is advantageous for making it easier to remove sanitary paper 90 smoothly.
  • the curve rate of the fold line 34 is equal to the curve rate of the fold line 32.
  • the curve rate of the fold line 34 may be greater or smaller than the curve rate of the fold line 32.
  • both the fold line 32 and the fold line 34 are curved.
  • only one of the fold line 32 or the fold line 34 may be curved.
  • the fold line 32 is curved and bulges outward from the folded piece 22, while the fold line 34 is straight.
  • folding pieces 22 and 24 are provided on main surface 12.
  • only one of folding pieces 22 or 24 may be provided on main surface 12, as shown in FIG. 20, for example.
  • only folding piece 22 is provided on main surface 12.
  • folding line 32 and folding line 34 only folding line 32 is provided on main surface 12.
  • cut line 44 extends from one end of folding line 32 to one end of cutting line 42.
  • cut line 46 extends from the other end of folding line 32 to the other end of cutting line 42.
  • folding piece 24 and fold line 34 correspond to the "first folding piece" and "first fold line", respectively.
  • the main body 10 may store multiple sanitary paper 90, for example, as shown in Figures 21 and 22.
  • Figure 22 is a diagram for explaining the structure of the end face along the line XXII-XXII in Figure 21.
  • two sanitary paper 90 are stored in the main body 10.
  • a partition 10a is provided in the main body 10 to separate the two sanitary paper 90.
  • the main surface 12 has multiple folding pieces 22 and multiple fold lines 32 to correspond to the multiple sanitary paper 90.
  • one folding piece 22 creates an opening in the main surface 12 that forms an outlet for one sanitary paper 90
  • the other folding piece 22 creates an opening in the main surface 12 that forms an outlet for the other sanitary paper 90
  • the main surface 12 has multiple folding pieces 24 and multiple fold lines 34 to correspond to the multiple sanitary paper 90.
  • sanitary papers 90 are stored in the main body 10 in this way, convenience for the user is improved. For example, if multiple different types of sanitary papers 90 are stored in the main body 10, the user can selectively remove the appropriate sanitary paper 90 from the main body 10 depending on the application. Also, by providing multiple folding pieces 22 and multiple folds 32 to correspond to multiple sanitary papers 90, the multiple sanitary papers 90 can be removed from separate removal openings. This prevents multiple sanitary papers 90 from interfering with each other, allowing each sanitary paper 90 to be removed smoothly.
