Description

[[Technical Field]]

[0001] The present invention relates to a toilet device and an attachment for a toilet device. [[Background Art]]

[0002] As a portable toilet device, there is known a device in which excrement is put into a thermoplastic cylindrical film, sealed by a film sealing device with a heater, further cut, and the contents are individually packaged (see, for example, Patent Document 1).

[0003] For portable toilets, considering situations such as disasters, ease of transport and light weight are emphasized, and they are basically configured to have fewer components. Therefore, highly convenient functions for users such as the washing toilet seat that is widely adopted in fixed toilets are not installed, and the configuration mainly focuses on the excrement treatment function. [[Prior Art Documents]] [[Patent Documents]]

[0004] [[Patent Document 1]] Japanese Unexamined Patent Application Publication No. 2018-99153 [[Summary of the Invention]] [[Problem to be Solved by the Invention]]

[0005] However, portable toilets are often used for leisure applications such as camping and sleeping in a vehicle, and in such cases, there are cases where it is required to address user convenience. However, in a portable toilet, a mechanism for treating excrement is installed inside the box body, and it has not been possible to replace the originally installed toilet seat with, for example, a toilet seat unit equipped with a washing function. In addition, when the originally installed toilet seat is replaced with another toilet seat unit, a gap is generated between the toilet seat unit and the box body, which allows excrement to easily enter areas other than the region where it should originally be stored, resulting in a hygienic problem.

[0006] The present invention aims to solve these problems and to provide a portable toilet device and an attachment for the toilet device that can be used hygienically even when the toilet seat unit is replaced. [Means for solving the problem]

[0007] The toilet device according to the present invention is a portable toilet device comprising: a box body in which a waste disposal mechanism is installed inside; an attachment installed on the upper surface of the box body; and a toilet seat unit installed so as to cover the upper surface of the attachment. The waste disposal mechanism is located at the top of the box body and includes a film storage section for housing a cylindrical film member, the film storage section being arranged in a ring shape when viewed from above; the toilet seat unit comprising a toilet seat portion on which the user sits and a main body portion to which the rear portion of the toilet seat portion is connected; the attachment comprising an inner peripheral edge portion surrounding an opening for waste to pass through, and a contact surface located outside the inner peripheral edge portion when viewed from above and in contact with the toilet seat unit, the tip of the inner peripheral edge portion being located inside the film storage section of the waste disposal mechanism when viewed from above. Furthermore, the attachment according to the present invention is an attachment for installing a toilet seat unit in a portable toilet device that has a waste disposal mechanism, including a film storage section for housing a cylindrical film member, inside a box body, and comprises an inner peripheral edge surrounding an opening for waste to pass through, a contact surface positioned outside the inner peripheral edge when viewed from above and in contact with the toilet seat unit, a positioning structure that restricts the horizontal movement of the toilet seat unit around the contact surface, and a bottom surface positioned outside the inner peripheral edge when viewed from below and in contact with the box body, wherein the tip of the inner peripheral edge is located at the same position as or inside the inner end of the film storage section of the waste disposal mechanism when viewed from above. [Effects of the Invention]

[0008] According to the above method, by applying an attachment to the top surface of the portable toilet, the occurrence of gaps when the box body and toilet seat unit are combined can be suppressed, allowing for hygienic use. This makes it possible to mount the desired toilet seat unit on a portable toilet equipped with a waste disposal mechanism. [Brief explanation of the drawing]

[Figure 6] This shows the structure of attachment 20 as seen from the bottom side (box side 10). [Figure 7] This is a schematic cross-sectional view of the toilet device 100 according to Embodiment 1. [Figure 8] This figure shows a toilet seat unit 30 of the toilet device 100 according to Embodiment 1, where (a) is a perspective view and (b) is a bottom view. [Figure 9] This figure shows a modified example of attachment 20. [Modes for carrying out the invention]

[0010] Preferred embodiments of the toilet device 100 and attachment 20 of the present invention are described in detail below with reference to the drawings. The embodiments described below are preferred specific examples of the present invention and therefore have various technically preferred limitations. However, the scope of the present invention is not limited to these embodiments unless otherwise specified in the following description.

[0011] Embodiment 1 1. Configuration of toilet device 100 1.1 Overall configuration Fig. 1 is a perspective view of an example of the toilet device 100 according to Embodiment 1. The toilet device 100 is a portable toilet device, and includes a box body 10, an attachment 20 installed on an upper surface of the box body 10, and a toilet seat unit 30 installed so as to cover the upper surface of the attachment 20.

[0012] The box body 10 is internally provided with an excrement disposal mechanism 10a. In the present embodiment, as the box body 10, for example, a commercially available portable toilet from which the upper toilet seat structure has been removed can be used.

[0013] The toilet seat unit 30 is, for example, a commercially available toilet seat unit, and may be configured to be provided with a washing mechanism 33. A supply mechanism 40 that supplies water pressure for ejecting water from the washing mechanism 33 is connected to the toilet seat unit 30 provided with the washing mechanism 33. For example, the supply mechanism 40 may include a connection part 37 connected to the toilet seat unit 30, and a pump 41 capable of pressurizing liquid stored in a tank.

[0014] Fig. 2 is a perspective view of the toilet device 100 of Fig. 1 in a state where the toilet seat unit 30 is removed. The attachment 20 is a member used for installing the toilet seat unit 30 on a portable toilet, and is for stably installing the toilet seat unit 30 while preventing excrement from entering the excrement disposal mechanism 10a installed in the box body 10.

[0015] That is, when the toilet seat unit 30 is directly installed on the box body 10, it may be difficult to stably place the toilet seat part 35 of the toilet seat unit 30. Accordingly, the attachment 20 includes a contact surface 23 and a contact surface 24 on which the toilet seat part 35 and a main body part 34 can be placed.

[0016] Further, since the toilet seat unit 30 shown in Fig. 1 includes a cleaning mechanism, the attachment 20 may be provided with a recess 22 for arranging the cleaning mechanism. Note that the toilet seat unit 30 is not limited to one having the cleaning mechanism 33, and may be a toilet seat unit that does not include the cleaning mechanism 33. Even in this case, the basic configuration of installing the toilet seat unit 30 on the box body 10 via the attachment 20 remains the same.

[0017] 1.2. Configuration of Box Body 10 As shown in Fig. 1 and Fig. 2, the box body 10 is a casing that constitutes the main body of the toilet device 100, and includes an excrement disposal mechanism 10a inside the box body. The excrement disposal mechanism 10a is configured such that a tubular film F is installed inside the box body 10, excrement is wrapped with the film F, and the film F is sealed to enable disposal of the excrement.

[0018] Fig. 3 is a diagram showing main parts of the box body 10 of the toilet device 100 according to Embodiment 1. Note that the film F is not installed in Fig. 3. Fig. 4 is a top view showing a state where the film F is installed on the box body 10 shown in Fig. 3. Fig. 5 is a schematic cross-sectional view of the toilet device 100 according to Embodiment 1. Fig. 5 shows an xz cross-section of a central portion of the toilet device 100 shown in Fig. 1 in the y-direction (depth direction of the toilet device 100).

[0019] The film F is placed in the film storage section 11, indicated by the dashed line in Figure 4. The film storage section 11 is an area partitioned by a storage section housing 15, a lid 14 that covers the storage section housing 15 from above, and a box housing 10b. The inner end of the film storage section 11 is the end that defines the inner circumferential boundary of the film storage section 11 when viewed from above, and may be configured, for example, as the inner end surface 14a of the lid 14. The storage section housing 15 and the lid 14 are configured to hold the folded cylindrical film F in a predetermined position, allowing the film F to be stably installed, and to define the path for pulling out the film F, thereby making it easy for excrement to be introduced into the inside of the film F (for example, area P shown in Figure 5) and making it difficult for it to flow into areas other than area P. One end of the folded cylindrical film F is pulled out through the gap between the lid 14 and the box housing 10b, introduced into the central space of the box body 10, and then pulled out through the discharge hole 10d of the box body 10.

[0020] The waste disposal mechanism 10a includes a feed roller 12 that pulls the film F downward from the film storage section 11, and a constriction section 13 that constricts the film F. The film F is fed downward in predetermined amounts by the feed roller 12. Note that the feed roller 12 and constriction section 13 shown in Figure 5 are schematic representations of the feed roller 12 and constriction section 13 shown in Figure 3, and the actual configuration may differ in terms of, for example, the direction of operation and the arrangement of the parts, but the functions of feeding the film F and constricting the film F and pressing and cutting it with heat are the same.

[0021] The aperture section 13 is equipped with a heater to heat the film F. As a result, the film F, which is narrowed by the aperture section 13, is sealed by heat, and waste can be accumulated inside the film F (for example, in the region P shown in Figure 5).

[0022] The toilet device 100 operates the waste disposal mechanism 10a when the user operates the control unit 19 of the box body 10 after use, thereby discharging the package 90 containing the waste. Specifically, when the user operates the waste disposal mechanism 10a, the feed roller 12 moves the film F downward, moving the area containing the waste below the constriction section 13.

[0023] The constricting section 13 constricts the upper portion of the area containing the excrement and seals it with heat. Furthermore, the constricting section 13 cuts the sealed portion, separating the package 90, which contains the excrement, from the film F. The separated package 90 is discharged from the discharge hole 10d of the box body 10.

[0024] In this way, the waste disposal mechanism 10a seals the waste inside the film F, making it easy to dispose of, and can then discharge it as a package 90.

[0025] 1.3. Configuration of Attachment 20 As shown in Figure 2, the attachment 20 is installed on the top surface of the box body 10 and is a component for supporting the toilet seat unit 30. Figure 6 shows the structure of the attachment 20 as seen from the bottom side (box body 10 side). In addition to the function of stably installing the toilet seat unit 30, the attachment 20 is formed to prevent excrement and splashes from entering the excrement disposal mechanism 10a (especially the film storage section 11 side) installed inside the box body 10.

[0026] The attachment 20 has an opening A through which excrement passes, and around this opening A are contact surfaces 23 and 24 (see Figure 2) for contacting and supporting the toilet seat unit 30. The contact surface 23 is in contact with a support part 36 (see Figure 8) installed on the underside of the toilet seat portion 35 of the toilet seat unit 30. The contact surface 24 is on which the underside 34a of the main body portion 34 of the toilet seat unit 30 rests. This makes it easier to stably support the toilet seat portion 35 of the toilet seat unit 30 compared to when the toilet seat unit 30 is placed directly on the box 10.

[0027] Furthermore, the attachment 20 includes a positioning structure 25 that restricts the horizontal movement of the toilet seat unit 30 when it is placed on the attachment. The positioning structure 25 is designed to hold the toilet seat unit 30 in a predetermined position by contacting or engaging with a predetermined part of the outer circumference or lower surface of the toilet seat unit 30, thereby suppressing movement (shifting) of the toilet seat unit 30 in the x and / or y directions.

[0028] In this embodiment, the positioning structure 25 is formed to match the underside structure of the toilet seat portion 35 shown in Figure 8, and is provided, for example, to correspond to the position of the support portion 36. As a result, when the toilet seat unit 30 is placed, the position of the support portion 36 is restricted by the positioning structure 25, and horizontal displacement of the toilet seat unit 30 is suppressed.

[0029] However, the positioning structure 25 is not limited to the structure shown in Figure 2. In other words, the positioning structure 25 is not limited to a configuration corresponding to the support portion 36 provided on the toilet seat portion 35, but may be other structures. For example, the positioning structure 25 may be formed to abut against or engage with any other structure formed on the underside of the toilet seat portion 35, such as a projection, rib, step, recess, hole, or outer edge (in other words, any structure on the underside of the toilet seat portion 35 that can be used for positioning). Furthermore, the specific shape of the positioning structure 25 may be any structure that can restrict the horizontal movement of the toilet seat unit 30, such as a convex portion (rib, protrusion, boss, etc.), a wall-shaped guide portion, a step portion, a locking claw, a groove, or a notch. In addition, the positioning structure 25 may be provided at multiple locations spaced apart in the circumferential direction, or it may be provided continuously around the entire circumference.

[0030] Furthermore, as shown in Figure 5, the attachment 20 is equipped with inner peripheral edges 21 (21a, 21b, 21c) surrounding the opening A. The tips 29 (29a, 29b, 29c) of the inner peripheral edges 21 extend toward the inside of the box body 10, and are configured to prevent excrement, splashes, etc. from easily flowing around the area through which the film F passes toward the film storage section 11.

[0031] Specifically, as shown in Figure 5, the attachment 20 is configured to ensure that the film F is movable while minimizing the gap H formed between the tip 29 of the inner peripheral edge 21 and the film F. This makes it difficult for excrement, droplets, etc., to enter areas other than the area P formed by the film F in which the excrement is contained.

[0032] Furthermore, as shown in Figure 5, the width W of the tip of the inner peripheral edge 21 (in other words, the position of the tip of the inner peripheral edge 21 on the inner circumference side of the opening A) can be set to be at the same position as or inside the inner end of the film storage section 11 in the x direction (width direction of the toilet device 100). The inner end of the film storage section 11 is formed, for example, by the inner end surface 14a of the lid 14. This makes it easier for the path toward the film storage section 11 to be blocked by the inner peripheral edge 21 when viewed from above, thereby suppressing the intrusion of excrement, splashes, etc. into the film storage section 11.

[0033] The bottom structure shown in Figure 6 has a bottom surface 28 that contacts the box body 10 in order to stably place the attachment 20 on the box body 10. In addition, the box body 10 may have a protrusion 16 for fixing the toilet seat that was originally installed, so the attachment 20 may also have a structure 26 that covers this protrusion 16. The structure 26 is provided with a recessed housing 27 that can accommodate the protrusion 16. This suppresses interference with the protrusion 16 when placing the attachment 20 on the box body 10, and allows for good mounting.

[0034] Figure 7 is a schematic cross-sectional view of the toilet device 100 according to Embodiment 1. In Figure 7, a cross-section parallel to the yz plane is shown of the central part of the toilet device 100 in the x direction (width direction of the toilet device 100) as shown in Figure 1.

[0035] As shown in Figure 7, the attachment 20 is equipped with an opening A through which excrement passes, and around the opening A, structures such as inner peripheral edges 21 (e.g., 21b, 21c) are formed, taking into consideration the positional relationship with the film storage section 11 installed inside the box body 10. This prevents excrement or droplets from circling around to areas other than the excrement storage section P of the film F and entering the film storage section 11.

[0036] Here, the structure surrounding the opening A is not limited to the same structure for the front part (hereinafter also referred to as the front section) and the rear part (hereinafter also referred to as the rear section) for the user sitting on the toilet device 100, and different structures may be adopted depending on the purpose. That is, the basic positional relationship between the film storage section 11 and the attachment 20 is the same for the front and rear sections, while the front section may be configured with a structure that is even more advantageous in suppressing the intrusion of droplets, etc.

[0037] For example, on the front side shown in Figure 7, the tip 29b of the inner peripheral edge 21b may be formed to be located inside the inner end of the film storage section 11 (for example, the inner end surface 14a of the lid 14). Furthermore, in this embodiment, the tip 29b of the inner peripheral edge 21b is formed to be located below the upper end surface of the film storage section 11. Here, the upper end surface of the film storage section 11 is the upper end surface 14b of the lid 14 that covers the film storage section 11 from above. As a result, on the front side, it becomes more difficult for excrement or droplets to flow around to the film storage section 11, and the intrusion into areas other than the area P which is the excrement storage section can be further suppressed.

[0038] Furthermore, while the configuration in which the tip 29b is positioned below the upper end surface 14b, as described above, is advantageous in terms of preventing intrusion on the front side, it is not limited to this. For example, the positional relationship between the tip 29a of the inner peripheral edge 21a and the film storage portion 11, as described earlier (see Figure 5), may be set to be similar. That is, even on the front side, the tip 29 of the inner peripheral edge 21 may be positioned above the upper end surface 14b in the vertical direction (z direction), and at the same position as or inside the inner end of the film storage portion 11 (the inner end surface 14a of the lid portion 14) in the y direction (front-back direction).

[0039] On the other hand, on the rear side shown in Figure 7, if the toilet seat unit 30 is equipped with a washing mechanism 33, the attachment 20 may be provided with a relief shape to avoid the washing mechanism 33 in order to secure space for its placement. For example, as shown in Figure 2, it may be configured as a recess 22 in which a part of the attachment 20 is indented, or it may be configured as a shape in which a predetermined area including the inner peripheral edge 21c on the rear side is made to relieve the entire area. In other words, the attachment 20 only needs to have a shape that avoids the washing mechanism 33 so as not to interfere with it. This makes it less likely for the washing mechanism 33 to interfere with the attachment 20, and makes it easier to apply the toilet seat unit 30 equipped with a washing function to the portable box 10. However, regardless of the shape of the inner peripheral edge 21c, the tip 29c is set in the same position as the tip 29a or 29b of the inner peripheral edge 21 described above.

[0040] 1.4. Configuration of the toilet seat unit 30 (Figure 8) Figure 8 shows a toilet seat unit 30 of the toilet device 100 according to Embodiment 1, where (a) is a perspective view and (b) is a bottom view. The toilet seat unit 30 comprises a main body 34, a toilet seat 35 connected to the main body 34, and a lid 38 connected to the main body 34 that can open and close the toilet seat 35. That is, the toilet seat unit 30 has a configuration in which the toilet seat 35 and the lid 38 are supported on the main body 34 as a base.

[0041] The back surface 34a of the main body 34 functions, for example, as a mounting or support surface. When the toilet seat unit 30 is placed on the attachment 20, the back surface 34a contacts the contact surface 24 of the attachment 20, contributing to the positioning or support of the toilet seat unit 30. In addition, the back surface of the toilet seat portion 35 is provided with a support portion 36 that contacts the contact surface 23 of the attachment 20. The support portion 36 is for stably positioning the toilet seat portion 35 on the attachment 20.

[0042] The main body 34 may house a cleaning mechanism 33. The cleaning mechanism 33 is, for example, a mechanism for spraying liquid to clean the user's private parts, and has a cylindrical structure. The cleaning mechanism 33 is a mechanism for cleaning the user's private parts, and the cleaning mechanism 33 may be referred to as a "private area cleaning mechanism".

[0043] In this embodiment, the washing mechanism 33 is configured to move back and forth from the main body 34. The washing mechanism 33 may be configured to move back and forth in a slightly inclined position, for example, with its tip facing downwards. This makes it easier to ensure an appropriate spray direction and position during washing, and also makes it easier to suppress interference with the toilet seat 35.

[0044] The nozzle at the tip of the cleaning mechanism 33 is functionally configured to be located slightly below the toilet seat 35. For example, the nozzle may be positioned below the toilet seat 35 to ensure proper spray direction and position during cleaning, and to suppress interference with the toilet seat 35.

[0045] The toilet seat unit 30 may be equipped with, for example, a lever 39 as an operating part for moving the washing mechanism 33 forward and backward. The lever 39 is located on the main body 34 and moves the washing mechanism 33 forward and backward according to the user's operation.

[0046] The toilet seat unit 30 is equipped with a connection part 37 for supplying liquid to the washing mechanism 33 from the outside. The connection part 37 is, for example, a connection part of a supply mechanism 40 that is connected to the outside, and is for supplying liquid (for example, water) that is ejected from the washing mechanism 33.

[0047] The attachment 20 is positioned between the toilet seat unit 30 and the box body 10, and is configured to be positioned at an appropriate distance from the film F and the toilet seat unit 30. Therefore, even if the toilet seat unit 30 is equipped with a washing mechanism 33, and the washing mechanism 33 moves back and forth with its tip facing downwards, and the spraying part is located below the toilet seat 35, interference between the film F and the washing mechanism 33 can be suppressed.

[0048] Furthermore, the toilet seat unit 30 is not limited to one equipped with a washing mechanism 33; it may also be a toilet seat unit without a washing mechanism 33. In this case as well, the basic configuration of installing the toilet seat unit 30 on the box body 10 via the attachment 20 remains the same.

[0049] 1.5. Configuration of the cleaning mechanism As shown in Figure 1, the toilet device 100 may include a supply mechanism 40 that supplies liquid to a washing mechanism 33 provided in the toilet seat unit 30. The supply mechanism 40 includes a pump 41 and piping 42. The piping 42 is connected to a connection part 37 of the toilet seat unit 30. The supply mechanism 40 applies pressure to the liquid (e.g., water) using the pump 41 and supplies the liquid to the washing mechanism 33 via the piping 42.

[0050] Pump 41 may be configured as a manual pressure pump that generates liquid pressure by manual operation, for example. The manual pressure pump may be, for example, a manual pressure pump used in a sprinkler that can spray liquid in a mist or jet.

[0051] The connection between the piping 42 and the connector 37 may be configured to be detachable. This makes it easier to replace the toilet seat unit 30 and to handle it during transport and storage.

[0052] The specific configuration of the supply mechanism 40 is not limited to the above example, as long as it can supply liquid to the cleaning mechanism 33. For example, the pump 41 is not limited to a manual pump, but may also be an electric pump.

[0053] 2. Operation of the toilet device 100 and attachment 20 2.1 Positional relationship between attachment 20 and waste disposal mechanism 10a As shown in Figures 5 and 7, the attachment 20 is placed on the top surface of the box body 10 and is configured to allow excrement to be introduced into the interior (region P) of the film F through the opening A through which the excrement passes. The attachment 20 has an inner peripheral edge 21 around the opening A, and the tip 29 of the inner peripheral edge 21 extends inward into the box body 10. This makes it easier to block the path for excrement or droplets to flow around the opening A towards the film containment section 11, thereby suppressing intrusion into areas other than the region P of the film F which is the excrement containment section.

[0054] Furthermore, the position of the tip 29 of the inner peripheral edge 21 can be set in relation to the inner end of the film storage section 11 (for example, the inner end surface 14a of the lid 14). For example, when viewed from above, the tip 29 of the inner peripheral edge 21 can be set to be at the same position as or inside the inner end (inner end surface 14a) of the film storage section 11 in the x-direction. This makes it easier to block the path of leakage toward the film storage section 11, thereby increasing the effect of suppressing the intrusion of excrement or droplets.

[0055] Furthermore, on the front side (the side facing the user), the tip 29b of the inner peripheral edge 21b may be positioned inward from the inner end face 14a of the film storage section 11, and below the upper end face of the film storage section 11 (for example, the upper end face 14b of the lid 14), which is advantageous from the standpoint of preventing intrusion. This makes it more difficult for excrement or droplets to flow around to the film storage section 11 on the front side. On the other hand, such an inverted relationship is not essential, and even on the front side, it may be set in the same way as the basic positional relationship between the tip 29 of the inner peripheral edge 21 and the film storage section 11 described earlier (for example, at the same position as or inside the inner end face 14a).

[0056] 2.2 Positional relationship between attachment 20 and toilet seat unit 30 As shown in Figures 2 and 8, the toilet seat unit 30 is placed on the attachment 20. The attachment 20 has contact surfaces 23 and 24 that support the toilet seat unit 30, for example, the support portion 36 of the toilet seat portion 35 contacts the contact surface 23, and the back surface 34a of the main body portion 34 contacts the contact surface 24. This makes it easier to stably support the toilet seat unit 30 compared to when the toilet seat unit 30 is placed directly on the box body 10.

[0057] Furthermore, the attachment 20 includes a positioning structure that restricts the horizontal movement of the toilet seat unit 30 around the contact surfaces 23 and 24. Specifically, a protrusion is arranged around the contact surface 23 as a positioning structure 25, and the support portion 36 of the toilet seat portion 35 makes it less likely for the toilet seat unit 30 to shift during use, and makes it easier to maintain the relative position between the opening A and the toilet seat unit 30 within a predetermined range.

[0058] Furthermore, if the toilet seat unit 30 is equipped with a washing mechanism 33, the attachment 20 may have a relief shape to avoid the washing mechanism 33. For example, the relief shape may be configured as a recess 22 with a part of it indented, as shown in Figure 2, etc., or it may be configured as a shape that gives way to a predetermined area on the back side as a whole. In other words, the attachment 20 only needs to have a shape that avoids the washing mechanism 33 so as not to interfere with it.

[0059] 2.3. Function of Attachment 20 (Suppression of gaps around opening A) The attachment 20 is equipped with an inner peripheral edge 21 around the opening A, and the tip 29 of the inner peripheral edge 21 extends inward into the box body 10, making it easier to block the path through which excrement or droplets may flow towards the film storage section 11.

[0060] On the other hand, since the film F is discharged by the waste disposal mechanism 10a, a gap H is required between the tip 29 of the inner peripheral edge 21 and the film F, allowing the film F to move. The attachment 20 can be configured to allow the film F to move while minimizing the gap H as much as possible. This prevents waste or droplets from entering areas other than the area P where the waste is contained.

[0061] Furthermore, when viewed from above, the tip 29 of the inner peripheral edge 21 can be set to be at the same position or inward in the x-direction as the inner end of the film storage section 11 (for example, the inner end surface 14a of the lid section 14). This makes it easier to block the path of film wrapping around towards the film storage section 11, thereby enhancing the intrusion prevention effect.

[0062] 2.4. Operation of toilet device 100 (compatibility with commercially available toilet seat unit 30) The toilet device 100 is configured so as not to obstruct the operation of the waste disposal mechanism 10a even when the toilet seat unit 30 is installed on the box body 10 via the attachment 20. In other words, the attachment 20 can reduce the gap H necessary for the movement of the film F around the opening A, so as not to hinder the feeding of the film F by the feed roller 12, the crimping and cutting by the constricting section 13, and the discharge of the package 90.

[0063] On the other hand, if the toilet seat unit 30 is simply placed on the box body 10, a gap will be created between the toilet seat unit 30 and the box body 10, especially around the opening A, which could lead to undesirable sanitary situations such as waste entering the gap. In contrast, the attachment 20 is equipped with an inner peripheral edge 21 around the opening A, and its tip 29 can be set at the same position as or inside the inner end face 14a in the x direction, thereby preventing excrement or splashes from entering the film storage section 11.

[0064] Furthermore, even when the toilet seat unit 30 is equipped with a washing mechanism 33 and the washing mechanism 33 moves forward and backward, the attachment 20 is interposed between the box body 10 and the toilet seat unit 30, so that the toilet seat unit 30 is positioned upward away from the box body 10, and space is secured on the underside of the toilet seat unit 30. Therefore, interference between the film F and the washing mechanism 33 can be suppressed. As a result, by using the attachment 20, commercially available toilet seat units 30 (including those equipped with a washing function) can be easily applied to the box body 10 while maintaining the functionality of the waste disposal mechanism 10a. With the toilet device 100, a toilet device equipped with a washing mechanism 33 can be realized, even though it is a portable toilet device 100.

[0065] 2.5. Operation of the supply mechanism 40 The supply mechanism 40 applies pressure to a liquid (e.g., water) using a pump 41 and supplies the liquid to the connection part 37 of the toilet seat unit 30 via piping 42. As a result, the flushing mechanism 33 can spray liquid due to the pressure of the supplied liquid. The connection between the piping 42 and the connection part 37 may be configured to be detachable. This makes it easier to replace the toilet seat unit 30 and to handle it during transport and storage. Since the toilet device 100 can utilize a pump 41 that does not require electricity or other power sources, a toilet device equipped with a flushing mechanism 33 can be realized even in environments without electricity, such as during disasters.

[0066] 3. Modified example (Dividing and fastening structure of attachment 20) Figure 9 shows a modified example of the attachment 20. Unlike the configuration shown in Figure 6, where the attachment 20 is assembled integrally by resin welding or the like, this modified example of the attachment 20 is constructed by fastening multiple parts together with fastening members 60.

[0067] In Figure 9, the dashed lines indicate the boundaries (dividing lines) of the multiple parts that make up the attachment 20. For example, the attachment 20 shown in Figure 9 can be formed by dividing it into four parts 20a, 20b, 20c, and 20d, and by fastening these parts 20a to 20d with fastening members 60, the attachment 20 can be completed with an inner peripheral edge portion 21 (tip 29) around the opening A. The fastening members 60 may be, for example, bolts.

[0068] This configuration, in which the attachment 20 is divided into multiple parts, molded, and then assembled, can be advantageous from a moldability standpoint, even when the attachment 20 is relatively large as a component used in a toilet system. In other words, even when it is difficult to mold the attachment 20 as a single piece, it is easier to form the attachment 20 by dividing it into multiple parts, molding them, and then assembling them.

[0069] Furthermore, the configuration in which parts are fastened together by the fastening member 60 makes assembly work easier. In addition, even if a part of the attachment 20 is damaged, it is easy to reassemble by removing the fastening member 60, replacing only the damaged part, and fastening it again.

[0070] The number of parts is not limited to four. For example, attachment 20 may be divided into three parts, or into more than four parts. The number of divisions, division positions, and part shapes can be appropriately set according to design requirements such as moldability, assembly, and strength.

[0071] As described above, the attachment 20 is not limited to a configuration in which it is integrally assembled by resin welding or the like as shown in Figure 6, but may also be configured in which it fastens divided parts together as shown in Figure 9, or it may be configured in which it is integrally molded. The fastening member 60 is not limited to a bolt, but may be any fastening means capable of fixing multiple parts, such as a screw, nut, rivet, engaging claw, clamp, etc.

[0072] Although the present invention has been described above based on embodiments, the present invention is not limited to the configuration of the embodiments described above. For example, the dimensions of the toilet device 100 can be appropriately changed within the range that enables the functions described above to be realized. In short, it should be noted that the scope of the present invention also includes various modifications, applications, and uses that a person skilled in the art may make as needed.
