DETAILED DESCRIPTION OF THE INVENTION
[0010] A portable urinal toilet according to an embodiment of the present disclosure comprises a bag body, a resin fastener, a multi-layer fusion section, and a hole. The bag body is composed of a front resin film and a back resin film, and is fused at both side edges and a bottom edge. The resin fastener is provided on the inner surface of the bag body parallel to the upper edge of the front resin film. The multi-layer fusion section is provided on both ends of the bag body at a position including the resin fastener, and includes a part of the resin fastener. The holes each pass through the multi-layer fusion section, allowing a finger to be inserted (first configuration).
[0011] When using a portable toilet of the first configuration, the resin fasteners are released from their engagement, and the fingers of one hand are inserted into each hole and spaced apart. As the finger space narrows, the resin fasteners bend, and the spacing between the resin fasteners widens, with the multilayer fused portions at both ends serving as fulcrums. This allows the resin fasteners to open sufficiently, and the front and back resin films are spaced apart sufficiently at the upper edge of the front resin film. This allows the receiving opening of the bag to be fully opened with one hand, and the bag can also be stably supported with one hand. Therefore, the portable toilet of the first configuration is easy to use with one hand.
[0012] In the portable toilet described above, it is preferable that the backside resin film includes an extension that protrudes above the upper edge of the frontside resin film (second configuration). In this case, urine can be received by the extension. Therefore, the portable toilet of the second configuration further improves usability.
[0013] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In each drawing, the same or equivalent components are designated by the same reference numerals, and redundant description will not be repeated.
[0014] First Embodiment A portable urinal toilet 100 according to a first embodiment will be described with reference to FIGS. 1 to 6. FIG.
[0015] [Configuration of the portable urinal toilet 100] 1 is a plan view of a portable toilet 100 according to a first embodiment. Referring to FIG. 1, the portable toilet 100 includes a bag body 1, a resin fastener 2, a multi-layer fusion portion 3, and a hole 4.
[0016] (Bag body 1) The bag body 1 is composed of a front resin film 11 and a back resin film 12. The front resin film 11 has an upper edge 110, a first side edge 111, a second side edge 112, and a lower edge 113. The first side edge 111 extends downward from one end of the upper edge 110. The second side edge 112 extends downward from the other end of the upper edge 110. The lower edge 113 connects the lower end of the first side edge 111 and the lower end of the second side edge 112.
[0017] In the example shown in FIG. 1, the front resin film 11 has a rectangular shape, with the vertical dimension being greater than the horizontal dimension. The upper edge 110 extends linearly in the horizontal direction. The first side edge 111 is the side edge located at the left end of the front resin film 11 and extends linearly in the vertical direction. The second side edge 112 is the side edge located at the right end of the front resin film 11 and extends linearly in the vertical direction. The lower edge 113 is parallel to the upper edge 110 and extends linearly in the horizontal direction.
[0018] Fig. 2 is a cross-sectional view of the portable toilet 100 taken along line II-II in Fig. 1. Referring to Fig. 2, the back-side resin film 12 overlaps with the front-side resin film 11. Referring to Figs. 1 and 2, the back-side resin film 12 is fused to the front-side resin film 11 at a first side edge 111, a second side edge 112, and a lower edge 113 of the front-side resin film 11. In Fig. 1, the fused portions of the front-side resin film 11 and the back-side resin film 12 that overlap each other are indicated by hatching.
[0019] Therefore, the bag body 1 is formed by the front-side resin film 11 and the back-side resin film 12 overlapping the front-side resin film 11. The bag body 1 is fused at both side edges 111, 112 and a bottom edge 113. The top edge 110 of the bag body 1 is open to the outside. That is, the top edge 110 of the front-side resin film 11 and the part of the back-side resin film 12 corresponding to the top edge 110 of the front-side resin film 11 define the receiving opening of the bag body 1.
[0020] The front resin film 11 and the back resin film 12, that is, the bag body 1, are made of synthetic resin. The material of each of the resin films 11, 12 is polyethylene (PE), PP (polypropylene), or the like.
[0021] In this embodiment, the back-side resin film 12 includes an extension 121. The extension 121 protrudes upward beyond the upper edge 110 of the front-side resin film 11. Therefore, the extension 121 does not overlap with the front-side resin film 11. The vertical dimension LP (protrusion amount) of the extension 121 is, for example, 10 mm or more and 50 mm or less. In the example shown in FIG. 1 , the back-side resin film 12 has a rectangular shape, and its vertical dimension is larger than the vertical dimension of the front-side resin film 11 by the amount of the extension 121.
[0022] (Plastic fastener 2) The resin fastener 2 is provided on the inner surface of the bag body 1 in parallel with the upper edge 110 of the front resin film 11. Specifically, the resin fastener 2 is composed of a pair of a front belt portion 21 and a rear belt portion 22.
[0023] The front-side belt portion 21 is laminated on the inner surface 11i (Fig. 2) of the front-side resin film 11. The front-side belt portion 21 extends from the first side edge 111 to the second side edge 112 parallel to the upper edge 110 of the front-side resin film 11. The front-side belt portion 21 is arranged along the upper edge 110 of the front-side resin film 11. The front-side belt portion 21 may overlap the upper edge 110 of the front-side resin film 11, or may be spaced apart from the upper edge 110. The front-side belt portion 21 is bonded to the front-side resin film 11 over its entire area. The front-side belt portion 21 is bonded to the front-side resin film 11 by fusion bonding.
[0024] The back-side band portion 22 is laminated on the inner surface 12i (Fig. 2) of the back-side resin film 12 so as to overlap with the front-side band portion 21. Like the front-side band portion 21, the back-side band portion 22 extends from the first side edge 111 to the second side edge 112 parallel to the upper edge 110 of the front-side resin film 11. The back-side band portion 22 is arranged along the upper edge 110 of the front-side resin film 11. The back-side band portion 22 is joined to the back-side resin film 12 over its entire area. The method of joining the back-side band portion 22 to the back-side resin film 12 is fusion bonding. The back-side band portion 22 is combined with the front-side band portion 21 to form the resin fastener 2.
[0025] In this case, the portion of the front-side resin film 11 where the front-side belt portion 21 is laminated has a higher Young's modulus than the other portions. Therefore, the portion of the front-side resin film 11 where the front-side belt portion 21 is laminated is deformed when a high external force is applied, and returns to its original shape when the external force is released. Similarly, the portion of the back-side resin film 12 where the back-side belt portion 22 is laminated has a higher Young's modulus than the other portions. Therefore, the portion of the back-side resin film 12 where the back-side belt portion 22 is laminated is deformed when a high external force is applied, and returns to its original shape when the external force is released.
[0026] FIG. 3 is an enlarged view of the resin fastener 2 of the portable toilet 100 shown in FIG. 2. Referring to FIG. 3, the resin fastener 2 is formed by combining the front band portion 21 and the back band portion 22, which fit together. Specifically, the resin fastener 2 is formed by a recessed groove and a protruding strip corresponding to the recessed groove. In the example shown in FIG. 3, the front band portion 21 includes a recessed groove 211, and the back band portion 22 includes a protruding strip 221. The recessed groove 211 is provided in the front band portion 21 and extends parallel to the upper edge 110. The protruding strip 221 is provided in the back band portion 22 and extends so as to overlap with the recessed groove 211. However, the recessed groove may be provided in the back band portion 22, and the protruding strip may be provided in the front band portion 21. When the recessed groove 211 and the protruding strip 221 fit together, the bag body 1 formed by the front resin film 11 and the back resin film 12 is sealed.
[0027] In a typical example, the recessed grooves 211 and the protruding strips 221 of the resin fastener 2 are provided in a range of 5 mm or more and 30 mm or less downward from the upper edge 110 of the resin film 11.
[0028] The front and back strap portions 21 and 22, that is, the resin fastener 2, are made of synthetic resin. The strap portions 21 and 22 are made of a material such as polyethylene (PE) or polypropylene (PP).
[0029] (Multilayer fusion part 3) 1 , the multilayer fusion section 3 is provided at each end of the bag body 1 at a position including the resin fastener 2, and includes a part of the resin fastener 2. Specifically, the multilayer fusion section 3 is composed of a first multilayer fusion section 31 and a second multilayer fusion section 32.
[0030] The first multi-layer fused portion 31 is formed at one end of the resin fastener 2 in the overlapping portion between the front resin film 11 and the back resin film 12. The second multi-layer fused portion 32 is formed at the other end of the resin fastener 2 in the overlapping portion between the front resin film 11 and the back resin film 12. That is, the overlapping front resin film 11 and the back resin film 12 are further fused at both end portions of the front band portion 21 and the back band portion 22. Therefore, in each multi-layer fused portion 31, 32, four layers are laminated: the front resin film 11, the front band portion 21, the back band portion 22, and the back resin film 12. Each multi-layer fused portion 31, 32 is required to include both end portions of the front band portion 21 and the back band portion 22, and may also include portions other than these end portions. In FIG. 1, the multilayer fused portion 3 (first multilayer fused portion 31 and second multilayer fused portion 32) is shown by cross-hatching.
[0031] (Hole 4) The holes 4 each pass through the multilayer fused portion 3 and are provided so that fingers can be inserted therethrough. Specifically, the holes 4 are made up of a first hole 41 and a second hole .
[0032] The first hole 41 penetrates the first multilayer fused portion 31 and is provided so that a finger of the hand can be inserted therethrough. The second hole 42 penetrates the second multilayer fused portion 32 and is provided so that another finger of the hand can be inserted therethrough. When using the portable toilet 100, different fingers of one hand are inserted into the first hole 41 and the second hole 42, respectively. In the example shown in FIG. 1 , the first hole 41 and the second hole 42 have an oval shape. However, the shape of each of the holes 41, 42 may be circular or another shape (e.g., polygonal, or a combination of straight lines and curves). However, it is preferable that each of the holes 41, 42 has a smooth shape. Each of the holes 41, 42 can be formed by drilling the corresponding multilayer fused portion 31, 32.
[0033] [How to use the Portable Toilet 100] Figures 4 to 6 are schematic diagrams for explaining how to use the portable toilet 100. Figure 4 shows the state during preparation. Figures 5 and 6 show examples of how to use the portable toilet 100, with Figure 5 showing a first method of use and Figure 6 showing a second method of use.
[0034] When using the portable toilet 100, the user grasps the upper portions of the front resin film 11 and the back resin film 12 and slightly widens the gap between them, as shown in Figure 4. This disengages the resin fastener 2.
[0035] Next, in a first method of use, referring to FIG. 5 , the user inserts the thumb of his right hand from the backside resin film 12 side into the second hole 42. Furthermore, the user inserts a finger other than the thumb, for example, the middle finger, into the first hole 41 from the backside resin film 12 side. The user then narrows the distance between the fingers inserted into the holes 41, 42. As the distance between the fingers narrows, the distance between the first hole 41 and the second hole 42 narrows. This causes the portion of the resin fastener 2 between the holes 41, 42 to bend, and the distance between the front-side belt portion 21 and the back-side belt portion 22 widens, with the first multilayer fusion portion 31 and the second multilayer fusion portion 32 at both ends of the curved portion serving as fulcrums. As a result, the resin fastener 2 opens sufficiently, and the receiving opening of the bag body 1 opens sufficiently. The user can hold this state with one hand and release urine into the bag body of the portable toilet 100 through the receiving opening.
[0036] In the first method of use, the extension 121 of the backside resin film 12 is positioned near the palm. In this case, by using the extension 121 in an upright position, the extension 121 can collect urine and guide it into the pouch of the portable toilet 100. The first method of use is mainly suited for use by men.
[0037] In the second method of use, referring to FIG. 6, the user inserts the thumb of his right hand into the first hole 41 from the side of the front resin film 11. Then, the user inserts a finger other than the thumb, for example, the middle finger, into the second hole 42 from the side of the front resin film 11. Then, as in the first method, the user narrows the space between the fingers inserted into the holes 41 and 42. As a result, the resin fastener 2 opens sufficiently, and the receiving opening of the bag body 1 opens sufficiently. The user can hold this state with one hand and release urine into the bag body of the portable toilet 100 through the receiving opening.
[0038] In the second method of use, the extension 121 of the backside resin film 12 is positioned away from the palm. In this case, by using the toilet with the extension 121 facing sideways, the extension 121 can catch urine and guide it into the pouch of the portable toilet 100. The second method of use is mainly suited for use by women.
[0039] After use, the user spreads the distance between the fingers inserted in the holes 41, 42. As the distance between the fingers spreads, the distance between the first hole 41 and the second hole 42 also increases. This causes the front band portion 21 and the back band portion 22 to instantly restore their original shape and straighten, closing the resin fastener 2. This allows the resin fastener 2 to be fitted together immediately, thereby minimizing odor leakage.
[0040] [effect] When using the portable toilet 100 of this embodiment, the plastic fastener 2 is released, and the fingers of one hand are inserted into the first hole 41 and the second hole 42, respectively, to narrow the gap between the fingers. As the gap narrows, the front and back bands 21 and 22 constituting the plastic fastener 2 curve, widening the gap between the front and back bands 21 and 22, with the first and second multilayer fusion bonded portions 31 and 32 at their ends acting as fulcrums. This causes the plastic fastener 2 to fully open, and the front and back resin films 11 and 12 are fully separated at the upper edge 110 of the front and back resin films 11. Therefore, the opening of the bag 1 formed by the front and back resin films 11 and 12 can be fully opened with one hand, and the bag can be stably supported with one hand. Therefore, the portable toilet 100 of this embodiment is easy to use with one hand.
[0041] Furthermore, in the portable toilet 100 of this embodiment, the backside resin film 12 includes an extension 121. When in use, the extension 121 also curves as the front-side belt 21 and the back-side belt 22 curve. The shape of the extension 121 is stabilized by the curve. In this case, the extension 121 can receive urine and guide it into the bag body of the portable toilet 100. This further increases usability.
[0042] Second Embodiment A portable urinal toilet 100A according to the second embodiment will be described with reference to Figures 7 and 8. Figure 7 is a plan view of the portable toilet 100A according to the second embodiment. Figure 8 is a schematic diagram showing the portable toilet 100A shown in Figure 7 in use. The portable toilet 100A differs from the portable toilet 100 of the first embodiment in the configuration of the hole 4A.
[0043] 7, in the portable toilet 100A, the hole 4A is composed of a first hole 41A and a second hole 42A. The first hole 41A is composed of a C-shaped first cutout 411 and a first connecting portion 412. The first cutout 411 is formed in the first multi-layer fusion section 31. The first connecting portion 412 is a portion of the first multi-layer fusion section 31 between both ends of the first cutout 411. Specifically, the first connecting portion 412 corresponds to a straight line portion connecting both ends of the first cutout 411 (shown as an imaginary line with two dots and dashes in FIG. 7). In this case, the first cutout 411 penetrates the first multi-layer fusion section 31.
[0044] The second hole 42A is composed of a C-shaped second cut 421 and a second connection portion 422. The second cut 421 is formed in the second multi-layer fusion section 32. The second connection portion 422 is a portion of the second multi-layer fusion section 32 between both ends of the second cut 421. Specifically, the second connection portion 422 corresponds to a straight line portion connecting both ends of the second cut 421 (shown as an imaginary two-dot chain line in FIG. 7). In this case, the second cut 421 penetrates the second multi-layer fusion section 32.
[0045] 7, the first incision 411 and the second incision 421 have an elliptical arc shape. However, the shape of each incision 411, 421 may be any C-shape, and may be an arc shape or other shape (e.g., a curve, a combination of straight lines and curves, or a combination of straight lines). However, each incision 411, 421 preferably has a smooth C-shape. Each incision 411, 421 can be formed by performing incision processing on the corresponding multilayer fusion portion 31, 32.
[0046] 7 and 8, when using the portable toilet 100A, the user presses the inner portion 413 of the first slit 411 of the first multi-layer fused section 31 with their fingers. This forms a first hole 41A in the first multi-layer fused section 31, defined by the first slit 411 and the first connecting section 412. Furthermore, the user presses the inner portion 423 of the second slit 421 of the second multi-layer fused section 32 with their fingers. This forms a second hole 42A in the second multi-layer fused section 32, defined by the second slit 421 and the second connecting section 422. Then, the user can insert their fingers into each of the holes 41A, 42A.
[0047] In the first embodiment, drilling chips are generated when the first hole 41 and the second hole 42 are formed in the manufacturing process of the portable toilet 100. In contrast, in the case of the second embodiment, drilling chips are not generated in the manufacturing process of the portable toilet 100A. Therefore, it is possible to reduce waste management.
[0048] Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments, and various modifications are possible without departing from the spirit of the present disclosure.
[0049] For example, the extension 121 may be omitted from the back side resin film 12. In this case, in the bag body 1, the back side resin film 12 overlaps with the front side resin film 11 over the entire area. [Explanation of symbols]
