Summary of the Invention

Problems to be Solved by the Invention

[0008] However, since the simple toilet 101 of the background art needs to perform a plurality of assembly steps to change from the storage box form Sb to the toilet form St, even if a sudden urge to urinate or defecate is felt and one is in a hurry when in the storage box form Sb, there is a problem that one cannot start using it immediately.

[0009] In addition, as shown in FIG. 16, the simple toilet 101 of the background art includes a portion formed by engaging a protruding piece (121, 126, 123) such as an insertion piece with a hole (127, 122, 124) such as an insertion hole. Therefore, especially when in use in the toilet form St, if the user applies an excessive load to the toilet seat portion 108, there is a problem that the engagement may become disengaged or the insertion hole may be damaged.

Means for Solving the Problems

[0010] In order to solve the above problems, the simple toilet of the first invention is A simple toilet configured to be morphologically changeable between a toilet form that can be used as a toilet and a container form in which articles can be stored in an inner storage space, The toilet form includes a rectangular tubular body formed by outer plates on the front, rear, left, and right sides, a bottom portion closing the lower opening of the body, and a pair of first inner wall forming portions respectively connected to the upper sides of the outer plates on both the left and right sides. By being bent, A pair of inner walls respectively formed inside the both outer plates, and Inside the outer plate on the rear side, it is arranged parallel to the outer plate and formed by one or two or more rectangular plates having the same height as the outer plate a rear side reinforcing wall and a second inner wall forming portion connected to the upper side of the outer plate on the rear side. By being bent, in order from the outer plate side on the rear side of the second inner wall forming portion toward the tip side of the second inner wall forming portion It includes an upper rear wall, an inner rear wall, an inner bottom wall, and an inner front wall and a hidden metal part formed. The inner wall is formed in a cylindrical shape extending in the front-rear direction having the same height as the outer plate to which it is continuously provided by being bent along a plurality of folds extending in the front-rear direction provided in the first inner wall forming portion. The rear reinforcing wall is formed such that the rear end sides of the pair of inner walls are shorter in the front-rear direction than the rear end sides of the outer plates on both the left and right sides, and the left and right edge portions of the rear reinforcing wall are respectively disposed in the left and right gaps formed between the rear ends of the pair of inner walls and the inner surface of the outer plate on the rear side. The upper rear wall is bent along a fold extending in the left-right direction provided at the upper end of the outer plate on the rear side, and extends forward from the upper end through the upper side of the rear reinforcing wall. The inner rear wall is bent along a fold extending in the left-right direction provided at the front end of the upper rear wall, and extends downward between the pair of inner walls from the front end. The inner bottom wall is bent along a fold extending in the left-right direction provided at the lower end of the inner rear wall, and extends forward between the pair of inner walls from the lower end. The inner front wall / metal cover is bent along a fold extending in the left-right direction provided at the front end of the inner bottom wall, and extends from the front end of the inner bottom wall so that the tip projects above the body portion via between the pair of inner walls and above the outer plate on the front side, and the length in the vertical direction is formed shorter than the length in the front-rear direction of the inner bottom wall. The container form is in a state where the inner front wall and the hidden metal part in the toilet form are tilted backward and along the inner bottom wall.

[0011] According to this configuration, it is possible to simply and quickly change the form between the toilet form that can be used as a toilet and the container form in which items can be stored in the inner storage space. Further, the rear side reinforcing wall is positioned by being provided between the rear ends of the pair of inner walls and the outer plate on the rear side, and the pair of first inner wall forming portions and the second inner wall forming portion are configured to be positioned relative to each other by arranging the inner rear wall, the inner bottom wall, and the inner front wall and the hidden metal part of the second inner wall forming portion between the pair of inner walls formed by the pair of first inner wall forming portions. Therefore, it is not necessary to use the engaging structure of the insertion hole and the insertion piece, and the strength can be improved compared to the case of using the engaging structure. Further, the inner wall is formed in a cylindrical shape extending in the front-rear direction having the same height as the outer plate to which it is continuously provided by being bent along a plurality of folds extending in the front-rear direction provided in the first inner wall forming portion. According to this configuration, since the inner wall is formed in the cylindrical shape and there is no need to use the engaging structure of the insertion hole and the insertion piece, the strength can be improved as compared with the case of using the same engaging structure. Furthermore, the rear reinforcing wall is arranged in parallel with the outer plate on the rear side and is formed by one or two or more rectangular plates having the same height as the outer plate. According to this configuration, since the rear reinforcing wall is formed by one or two or more rectangular plates and there is no need to use the engaging structure of the insertion hole and the insertion piece, the strength can be improved as compared with the case of using the engaging structure.

[0016] Second invention As for the simple toilet, Said first invention in In the toilet form, at least two or more of the upper rear wall, the inner rear wall, the inner bottom wall, and the inner front wall and the hidden metal part in the second inner wall forming portion disposed between the pair of inner walls on the left and right.at each of the left and right ends is configured to support at a location inwardly away from the outer peripheral edge on the inner surface of the pair of left and right inner walls abut is exemplified.

[0017] According to this configuration, since the locations inwardly away from the outer peripheral edge on the inner surfaces of the both inner walls are supported over a wide range by the second inner wall forming portion, deformation of the both inner walls can be prevented when a load is applied to the both inner walls.

[0018] Third invention As the simple toilet, in the Second invention wherein the inner rear wall is formed such that the length in the height direction thereof is shorter than the height of the rear side reinforcing wall, the inner bottom wall is formed such that the length in the front-rear direction thereof is shorter than the length in the front-rear direction of the storage space is exemplified.

[0019] According to this configuration, since the length in the height direction of the inner rear wall is formed shorter than the height of the rear side reinforcing wall, the rear end portion of the inner bottom wall floats above the inner surface of the bottom portion, whereby the inner bottom wall is supported in an inclined state with a downward slope in the front. And, since the length in the front-rear direction of the inner bottom wall is formed shorter than the length in the front-rear direction of the storage space, the lower end portions of the inner front wall and the hiding member are located at positions separated rearward from the front side outer plate, whereby in the toilet form, the inner front wall and the hiding member are supported in an inclined state with an upward slope toward the upper end portion of the front side outer plate. Thus, in the toilet form, since the inner bottom wall and the inner front wall and the hiding member are arranged between the pair of left and right inner walls in a substantially V-shaped state, by supporting the wall surfaces of the both inner walls in a V-shape over a wide range in the front-rear direction, deformation of the both inner walls can be suppressed when a load is applied to the both inner walls. Moreover, since the inner bottom wall and the inner front wall and the hiding member are non-parallel to the constituent elements (the bottom portion with respect to the inner bottom wall, the front side outer plate with respect to the inner front wall and the hiding member) of the bottom portion or the body portion in their respective vicinities, twisting of the bottom portion and the body portion can be suppressed.

[0020] Fourth invention As the simple toilet, in the Second inventionIn this case, the upper rear wall is formed to protrude in the direction of the outer plate on the front side rather than the rear reinforcing wall, the inner rear wall is formed such that the lower end contacts the lower end of the rear reinforcing wall, The inner bottom wall exemplifies an aspect in which the length in the front-rear direction is formed shorter than the length in the front-rear direction of the storage space.

[0021] According to this configuration, since the upper rear wall is formed to protrude in the direction of the outer plate on the front side rather than the rear reinforcing wall, and the inner rear wall is formed such that the lower end contacts the lower end of the rear reinforcing wall, the upper rear wall and the inner rear wall support a portion farther forward than the rear end on the wall surfaces of the both inner walls. And since the length in the front-rear direction of the inner bottom wall is formed shorter than the length in the front-rear direction of the storage space, the lower end portion of the inner front wall / hide plate is located at a position separated rearward from the front outer plate, so that in the toilet form, the inner front wall / hide plate is supported in a forwardly rising inclined manner toward the upper end portion of the front outer plate, and supports a portion farther rearward than the front end on the wall surfaces of the both inner walls. Thus, in the toilet form, a portion separated inward from the outer peripheral edge on the inner surfaces of the both inner walls is widely supported by the second inner wall forming portion, so that deformation of the both inner walls can be suppressed when a load is applied thereto. Moreover, since the inner rear wall and the inner front wall / hide plate are non-parallel with respect to the component of the body portion (the rear outer plate with respect to the inner rear wall, the front outer plate with respect to the inner front wall / hide plate) in the vicinity thereof, torsional deformation of the body portion can be suppressed.

[0022] Fifth invention As a simple toilet of, the Fourth invention In this case, is provided with a projecting piece that is continuously provided at the lower end of the front outer plate and extends in parallel with the inner surface of the bottom by being bent in the direction of the rear outer plate, The tip of the projecting piece exemplifies an aspect in which it is configured to position the front end portion of the inner bottom wall so as not to shift in the front-rear direction.

[0023] According to this configuration, the integrality between the second inner wall forming portion and the body portion can be improved, and the strength of the entire simple toilet can be improved.

[0024] Sixth invention As the simple toilet of, the Fourth invention in, is provided with a projecting piece that is continuously provided at the lower end of the front outer plate and extends parallel to the inner surface of the bottom by being bent in the direction of the rear outer plate. An aspect is exemplified in which the front end portion of the inner bottom wall is configured to be placed on the tip end portion of the projecting piece.

[0025] According to this configuration, since the inner bottom wall is configured to be inclined so as to be lower toward the rear side, by supporting a portion of the inner bottom wall that is farther above than the lower ends on the wall surfaces of the both inner side walls, deformation of the both inner side walls can be suppressed when a load is applied to them. Moreover, since the inner bottom wall is non-parallel to the bottom in its vicinity, twisting of the bottom can be suppressed. Furthermore, the inclination can cause excrement to gather on the rear side.

[0026] Seventh invention As the simple toilet of, the First to sixth in any of the inventions of, An aspect is exemplified in which a lid formed in an open-top rectangular tubular shape is provided, which is formed so that the body portion fits therein.

[0027] According to this configuration, by covering the body portion with the lid from above so as to close the opening of the body portion, it can be used in the form of a storage box. Also, by covering the body portion with the lid from below, the body portion can be reinforced when used in the toilet form.

[0028] Also, Eighth invention the toilet set of, stores toilet-related supplies in the storage space of the simple toilet in any of the above-described container forms.

[0029] The toilet-related supplies are not particularly limited, but the following supplies are exemplified. (1) A feces storage bag to be installed inside the body when the portable toilet is in the form of a toilet. (2) Agents (coagulants, deodorants, bactericides, fragrances, etc.) to be put into the feces storage bag. (3) A portable urine collection container that can be used alone without being attached to the portable toilet.

[0030] According to this configuration, since the toilet-related supplies are stored in the storage space to form a set, both can be managed integrally. And, for example, if a large number of the feces storage bags and the agents are set as the toilet-related supplies, it will be convenient when multiple people share the portable toilet in an evacuation facility or the like. Also, if a portable urine collection container for urination, which can be used separately from the portable toilet, is set as the toilet-related supply, when multiple people share the portable toilet, the congestion of toilet users can be reduced and it becomes even more convenient.

Advantages of the Invention

[0031] According to the portable toilet and the toilet set according to the present invention, there is an excellent effect that the form can be easily and quickly changed between a toilet form that can be used as a toilet and a container form that can store items in the inner storage space.

Modes for Carrying Out the Invention

[0033] Figs. 1 to 7 show the simple toilet 1 and the toilet set according to the first embodiment embodying the present invention. As shown in Figs. 1 and 2, the simple toilet 1 includes a box body 11 and a lid 12 made of cardboard, and is configured to be capable of changing its form between a toilet form St that can be used as a toilet and a container form Sb in which items can be stored in an inner storage space A. Note that the thin dashed line and the thin solid line in Fig. 6 respectively indicate a mountain-fold bending line and a valley-fold bending line.

[0034] First, the toilet form St will be described. As mainly shown in Figs. 1 to 3 and Fig. 6, this toilet form St includes a rectangular cylindrical body portion 15 formed by outer plates 2, 3, 4, 4 on the front, rear, left, and right sides, a bottom portion 16 that closes the lower opening of the body portion 15, and a pair of first inner wall forming portions 5 respectively connected to the upper sides of the outer plates 4, 4 on both the left and right sides, so that a pair of inner walls 17 are respectively formed inside the two outer plates 4, 4, a rear reinforcing wall 18 provided between the rear ends of the pair of inner walls 17 and the rear outer plate 3, and a second inner wall forming portion 6 connected to the upper side of the rear outer plate 3. The second inner wall forming portion 6 projects upward from above the rear reinforcing wall 18 between the pair of inner walls 17, 17, passes through the inside of the bottom portion 16 and the inside of the front outer plate 2, and a top rear wall 19, an inner rear wall 20, an inner bottom wall 21, and an inner front wall and hiding portion 22 are formed (see Fig. 3(a)).

[0035] The inner wall 17 is formed into a cylindrical shape extending in the front-rear direction having the same height as the outer plate 4 to which it is connected in series by being bent along a plurality of folding lines extending in the front-rear direction provided in the first inner wall forming portion 5. The length of the inner wall 17 in the front-rear direction is formed shorter than the inner dimension of the body portion 15 in the front-rear direction so that the rear reinforcing wall 18 can be inserted between the rear end portion of the inner wall 17 and the rear outer plate 3.

[0036] The rear reinforcing wall 18 is formed by a plurality of (not particularly limited, but four in this example) rectangular plates 7 having the same height as the outer plate 3 in this example, and is arranged in parallel with the outer plate 3 on the rear side. In this example, the four rectangular plates 7 are not adhered to each other, but if they are adhered, the strength can be further improved. Note that the rear reinforcing wall 18 may be formed of a single thick rectangular plate.

[0037] The inner rear wall 20 is formed such that the length in its height direction is shorter than the height of the rear reinforcing wall 18.

[0038] The inner bottom wall 21 is formed such that the length in its front-rear direction is shorter than the length in the front-rear direction of the storage space A.

[0039] The inner front wall and hiding plate 22 is formed such that the length in its vertical direction is shorter than the length in the front-rear direction of the inner bottom wall 21, and as shown in FIG. 5, in the container form Sb, it can be tilted backward along the inner bottom wall 21. An arc-shaped notch 22a is provided at the upper end of the inner front wall and hiding plate 22 to facilitate hanging a finger when changing the form between the toilet form St and the container form Sb.

[0040] The lid 12 is formed in an open-top rectangular tube shape in which the body portion 15 can be fitted inside. When used as a toilet, by mounting this lid 12 upward on the lower side of the box body, it can be used to reinforce the periphery of the body portion 15.

[0041] Next, regarding the container form Sb, mainly as shown in FIGS. 4 and 5, this container form Sb is in a state where the inner front wall and hiding plate 22 in the toilet form St is tilted backward and along the inner bottom wall 21.

[0042] Next, the toilet set of the present invention will be described. This toilet set stores toilet-related supplies 30 in the inner storage space A in the container form Sb.

[0043] Although the toilet-related supplies 30 are not particularly limited, the following supplies are exemplified. (a) A feces storage bag to be attached when the simple toilet 1 is in the toilet form St. (b) Agents (coagulants, deodorants, bactericides, fragrances, etc.) to be put into the feces storage bag. (c) A portable urine collection container that can be used alone without being attached to the simple toilet 1.

[0044] Next, the manufacturing method of the simple toilet 1 of the present invention will be described mainly with reference to FIGS. 6 and 7. To assemble the plate material shown in the reduced development view into a usable toilet, first, each part is bent along each fold line shown in the development view with fold lines, and the paste margin piece 8 on one end side of the body part 15 is adhered to the other end side of the body part 15 to form a square tube-shaped body part 15 (see FIG. 7(a)). Next, the bottom part 16 is formed by fixing the inner surfaces of the pair of bottom plates 10, 10 on the outer surfaces of the pair of bottom plate flaps 9, 9 with fixing means such as tape and adhesive (see FIG. 7(b)). Next, the left and right first inner wall forming parts 5, 5 are bent in order from the folds at their respective tip sides into a cylindrical shape and folded into the inside of the body part 15 to form the left and right inner walls 17 (see FIG. 7(c)). Next, a rear reinforcing wall 18 is inserted between the rear ends of the both inner walls 17 and the rear wall of the body part 15 (see FIG. 7(d)). Finally, by bending the second inner wall forming part 6 continuously provided on the rear wall of the body part 15 at each fold line, the upper rear wall 19, the inner rear wall 20, the inner bottom wall 21, and the inner front wall and the hiding part 2 are formed and it is completed (see FIG. 2).

[0045] Next, the usage method when the simple toilet 1 of the present invention is in the toilet form St will be described. When using the toilet, the bottom side of the feces storage bag is put inside the body part 15, and the opening side of the feces storage bag is turned inside out and covered outside the body part 15, and agents such as coagulants, deodorants, and bactericides are put into the feces storage bag for use (see FIG. 8(4)). After using the toilet, the feces storage bag is removed from the simple toilet 1, and the sealing part is tied to seal the feces storage bag, and it is disposed of in this state.

[0046] According to the simple toilet 1 of this example configured as described above, it is possible to easily and quickly change the form between the toilet form St that can be used as a toilet and the container form Sb in which items can be stored in the inner storage space A. Further, the rear reinforcing wall 18 is positioned by being provided between the rear ends of the pair of inner walls 17, 17 and the outer plate 3 on the rear side, and the pair of first inner wall forming parts 5 and the second inner wall forming part 6 are arranged such that the inner rear wall 20, the inner bottom wall 21, and the inner front wall and hidden metal 22 of the second inner wall forming part 6 are disposed between the pair of inner walls 17, 17 formed by the pair of first inner wall forming parts 5, so that they are positioned relative to each other. Therefore, it is not necessary to use the engaging structure of the insertion hole and the insertion piece, and the strength can be improved compared to the case of using the engaging structure.

[0047] Further, the inner wall 17 is formed into a cylindrical shape extending in the front-rear direction having the same height as the outer plate 4 to which it is continuously provided by being bent along a plurality of folds extending in the front-rear direction provided in the first inner wall forming part 5. According to this configuration, since the inner wall 17 is formed into the cylindrical shape and it is not necessary to use the engaging structure of the insertion hole and the insertion piece, the strength can be improved compared to the case of using the engaging structure.

[0048] Further, the rear reinforcing wall 18 is arranged in parallel with the outer plate 3 on the rear side and is formed by one or two or more rectangular plates 7 having the same height as the outer plate 3. According to this configuration, since the rear reinforcing wall 18 is formed by one or two or more rectangular plates and it is not necessary to use the engaging structure of the insertion hole and the insertion piece, the strength can be improved compared to the case of using the engaging structure.

[0049] In addition, since the length of the inner rear wall 20 in the height direction is formed to be shorter than the height of the rear reinforcing wall 18, the rear end portion of the inner bottom wall 21 floats above the inner surface of the bottom portion 16, whereby the inner bottom wall 21 is supported in a forwardly downwardly inclined state. And, since the length of the inner bottom wall 21 in the front-rear direction is formed to be shorter than the length of the storage space A in the front-rear direction, the lower end portion of the inner front wall / trim 22 is located at a position separated rearward from the front outer side plate, whereby in the toilet form St, the inner front wall / trim 22 is supported in a forwardly upwardly inclined state toward the upper end portion of the front outer side plate. Thus, in the toilet form St, since the inner bottom wall 21 and the inner front wall / trim 22 are arranged between the pair of left and right inner side walls 17 in a substantially V-shaped state, by supporting the wall surfaces of the both inner side walls 17 in a wide range in the front-rear direction in the V-shape, deformation of the both inner side walls 17 can be suppressed when a load is applied thereto. Moreover, since the inner bottom wall 21 and the inner front wall / trim 22 are non-parallel to the components of the bottom portion 16 or the body portion 15 in their respective vicinity (the bottom portion 16 with respect to the inner bottom wall 21, the front outer side plate 2 with respect to the inner front wall / trim 22), twisting of the bottom portion 16 and the body portion 15 can be suppressed.

[0050] Further, it is provided with a lid 12 formed in a square cylindrical shape with a top, which is formed so that the body portion 15 fits therein on the inside. According to this configuration, by covering the lid 12 over the body portion 15 from above so as to close the opening of the body portion 15, it can be used in the form of a storage box. Also, by covering the lid 12 under the body portion 15, the body portion 15 can be reinforced when used in the toilet form St.

[0051] Furthermore, the toilet set of this example stores toilet-related supplies 30 in the inner storage space A in the container form Sb. According to this configuration, since the toilet-related supplies 30 are stored in the storage space A to form a set, both can be managed integrally. And, for example, if a number of the feces storage bags and the medicine are set as the toilet-related supplies 30, it will be convenient when a plurality of people share the simple toilet 1 in an evacuation facility or the like. Also, if a portable urine collection container for urination that can be used separately from the simple toilet 1 is set as the toilet-related supplies 30, when a plurality of people share the simple toilet 1, the congestion of toilet users can be reduced and it becomes even more convenient.

[0052] Next, FIGS. 8 to 13 show the simple toilet 1 and the toilet set according to the second embodiment embodying the present invention. The simple toilet 1 and the toilet set of this embodiment are mainly different from the first embodiment in the following points. Therefore, for the parts common to the same embodiment, the same reference numerals are given to omit redundant explanations.

[0053] As shown in FIGS. 8 and 9, the simple toilet 1 includes a box body 11 and a lid 12 made of cardboard, and is configured to be capable of changing its form between a toilet form St that can be used as a toilet and a container form Sb that can store items in the inner storage space A. Note that the thin dashed line and the thin solid line in FIG. 13 respectively indicate a mountain-fold bending line and a valley-fold bending line.

[0054] First, regarding the toilet form St of this example, mainly as shown in FIGS. 8 to 10 and FIG. 13, this toilet form St includes a rectangular tube-shaped body portion 15 formed by outer plates 2, 3, 4, and 4 on the front, rear, left, and right sides, a bottom portion 16 that closes the lower opening of the body portion 15, and a pair of first inner wall forming portions 5 respectively connected to the upper sides of the outer plates 4 and 4 on both the left and right sides, whereby a pair of inner walls 17 are respectively formed inside the two outer plates 4 and 4, a rear reinforcing wall 18 provided between the rear ends of the pair of inner walls 17 and the rear outer plate 3, and a second inner wall forming portion 6 connected to the upper side of the rear outer plate 3. The second inner wall forming portion 6 projects upward from the upper side of the rear reinforcing wall 18 between the pair of inner walls 17, 17, passes through the inside of the bottom portion 16 and the inside of the front outer plate 2, and has a tip projecting above the body portion 15, thereby forming (see FIG. 10(a)) an upper rear wall 19, an inner rear wall 20, an inner bottom wall 21, and an inner front wall / hideaway 22.

[0055] In this example, the rear reinforcing wall 18 is formed by a plurality of (not particularly limited, but 5 in this example) rectangular plates 7 having the same height as the outer plate 3. Note that the rear reinforcing wall 18 may be formed by a single thick rectangular plate.

[0056] The upper rear wall 19 is formed so as to project in the direction of the outer plate 2 on the front side of the rear reinforcing wall 18.

[0057] The inner rear wall 20 is formed such that its lower end contacts the lower end of the rear reinforcing wall 18.

[0058] The inner bottom wall 21 is formed such that its length in the front-rear direction is shorter than the length in the front-rear direction of the storage space A.

[0059] Both ends in the width direction of the upper end of the inner front wall / hideaway 22 are chamfered in an R (round) shape so as not to damage the feces storage bag when covering the feces storage bag.

[0060] Next, regarding the container form Sb of this example, mainly as shown in FIGS. 11 and 12, this container form Sb is in a state where the inner front wall / hideaway 22 in the toilet form St is tilted backward and along the inner bottom wall 21.

[0061] Next, the toilet set of the present invention will be described. As shown in FIG. 11, this toilet set stores toilet-related supplies 30 in the inner storage space A in the container form Sb.

[0062] Next, the manufacturing method of the simple toilet 1 of the present invention will be described. To assemble the plate material shown in the reduced development view of FIG. 13 so that it can be used as a toilet, first, each part is bent along each bending line shown in the development view with bending lines, and the paste margin piece 8 on one end side of the body part 15 is adhered to the other end side of the body part 15 to form a rectangular tube-shaped body part 15. In this way, the paste margin piece 8 in this example is formed in the same shape as the outer side plate 3 on the rear side to which it is adhered, so as to ensure a wide adhesion surface and prevent a gap from being formed between the inner surface on the rear side of the body part 15 and the rear side reinforcing wall 18, thereby improving the strength on the rear side of the body part 15 compared to the first embodiment.

[0063] Next, the bottom part 16 is formed by fixing the inner surfaces of the pair of bottom plates 10, 10 to the outer surface of the protruding piece 25 by fixing means such as tape or adhesive. In this way, in the simple toilet 1 of this example, it is provided with a protruding piece 25 that is continuously provided at the lower end of the front outer side plate 2 and extends parallel to the inner surface of the bottom part 16 by being bent in the direction of the rear outer side plate 3.

[0064] Next, the left and right first inner wall forming parts 5, 5 are bent in sequence from the folds at the tip ends to form a cylindrical shape and folded into the inside of the body part 15 to form the left and right inner side walls 17 (similar to FIG. 7(c) of the first embodiment). Next, a rear side reinforcing wall 18 is inserted between the rear ends of the both inner side walls 17 and the rear wall of the body part 15 (similar to FIG. 7(d) of the first embodiment). Finally, by bending the second inner wall forming part 6 continuously provided on the rear wall of the body part 15 at each fold, the upper rear wall 19, the inner rear wall 20, the inner bottom wall 21, and the inner front wall and the hiding part 2 are formed. Then, when the front end part of the inner bottom wall 21 is locked to the tip of the protruding piece 25 and positioned so that it does not shift in the front-rear direction, it is completed (see FIG. 9).

[0065] Note that the usage method of the simple toilet 1 of the present invention when it is in the toilet form St is the same as that of the simple toilet 1 in the first embodiment.

[0066] Also, with the simple toilet 1 and the toilet set of this example configured as described above, for the parts having the same configuration as those in the first embodiment, the same effects as those in the same embodiment can be obtained.

[0067] Further, the upper rear wall 19 is formed so as to project in the direction of the outer plate 2 on the front side rather than the rear reinforcing wall 18, and the inner rear wall 20 is formed such that the lower end contacts the lower end of the rear reinforcing wall 18. Therefore, the upper rear wall 19 and the inner rear wall 20 support a portion that is farther forward than the rear end on the wall surfaces of the both inner side walls 17. And since the length of the inner bottom wall 21 in the front-rear direction is formed shorter than the length of the storage space A in the front-rear direction, the lower end portion of the inner front wall and hiding part 22 is at a position separated rearward from the front outer plate 2. As a result, in the toilet form St, the inner front wall and hiding part 22 is supported in a forwardly rising inclined shape toward the upper end portion of the front outer plate 2, and supports a portion that is farther rearward than the front end on the wall surfaces of the both inner side walls 17. In this way, in the toilet form St, a portion that is separated inward from the outer peripheral edge on the inner surfaces of the both inner side walls 17 is widely supported by the second inner wall forming portion 6. Therefore, when a load is applied to the both inner side walls 17, their deformation can be suppressed. Moreover, the inner rear wall 20 and the inner front wall and hiding part 22 are non-parallel with respect to the components of the body portion 15 (the outer plate 3 on the rear side with respect to the inner rear wall 20, the outer plate 2 on the front side with respect to the inner front wall and hiding part 22) in their respective vicinities. Therefore, the torsional deformation of the body portion 15 can be suppressed.

[0068] Furthermore, in the simple toilet 1 of this example, a projecting piece 25 is provided which is continuously provided at the lower end of the front outer plate 2 and extends in parallel with the inner surface of the bottom portion 16 by being bent in the direction of the rear outer plate 3. The tip of the projecting piece 25 is configured to position the front end portion of the inner bottom wall 21 so as not to shift in the front-rear direction. According to this configuration, the integrality between the second inner wall forming portion 6 and the body portion 15 can be improved, and the strength of the entire simple toilet 1 can be improved.

[0069] Next, FIG. 14 shows a simple toilet 1 and a toilet set according to a third embodiment embodying the present invention. The simple toilet 1 and the toilet set of this embodiment are mainly different from the second embodiment in the following points. Therefore, for the parts common to the same embodiment, the same reference numerals are given to omit redundant explanations.

[0070] In the simple toilet 1 of this example, a projecting piece 25 is provided at the lower end of the front outer plate 2 and extends parallel to the inner surface of the bottom 16 by being bent in the direction of the rear outer plate 3. The front end portion of the inner bottom wall 21 is configured to be placed on the tip of the projecting piece 25.

[0071] Also, with the simple toilet 1 and the toilet set of this example configured as described above, for the parts configured in the same manner as those of the second embodiment, the same effects as those of the same embodiment can be obtained.

[0072] Moreover, according to the above-described configuration, since the inner bottom wall 21 is configured to incline so as to be lower toward the rear side, by supporting a portion of the inner bottom wall 21 that is farther above the lower ends of the wall surfaces of the both inner side walls 17, deformation of the both inner side walls 17 when a load is applied thereto can be suppressed. In addition, since the inner bottom wall 21 is non-parallel to the bottom 16 in the vicinity thereof, torsion of the bottom 16 can be suppressed. Further, the inclination allows excrement to gather on the rear side.

[0073] Note that the present invention is not limited to the above-described embodiment, and can be embodied by appropriately changing, for example, as follows without departing from the gist of the invention. (1) Appropriately change the material of the simple toilet 1. (2) Appropriately change the shape and size of each part of the simple toilet 1. (3) Change the configuration of the rear reinforcing wall 18. For example, an embodiment formed in a substantially cylindrical shape extending in the left-right direction or the up-down direction can be mentioned.
