The present invention is a bag made of a very thin film of linear low density polyethylene (LLDPE (Linear Low Density Poiythylene)), and this cylindrical film is folded into a plurality of ridges and laminated to form a bottom portion. A portable toilet set 5 in which a bag 81 containing coagulant 6, instruction manual 7, and hand-washing water 8 is made into a very small set using a waste disposal bag that is heat-sealed and has a round bottom at the time of use. It is.
The preferred embodiments of the portable toilet set of the present invention will be described below with reference to the drawings.

The excrement disposal bag of the embodiment of the present invention uses a very thin film of linear low density polyethylene (LLDPE), and the thickness thereof is 5 to 15 μm, preferably 10 μm (0.01 mm). Is used.
This linear low density polyethylene, also called Linear Low Density Polyethylene-L-LDPE, is a synthetic resin that belongs to a thermoplastic resin, copolymerized with a repeating unit of ethylene and a small amount of α-olefin. In K6899-1: 2000, linear polyethylene is defined as a linear polyethylene copolymer having a density of 0.910 to 0.925. Used in adhesives for food packaging, etc., excellent pinhole resistance, rigidity and flexibility are located between HDPE and LDPE, excellent in heat resistance, water resistance, chemical resistance, oil resistance and surfactant The resistance to stress cracking (environmental stress cracking) exceeds that of HDPE and LDPE.

As shown in FIG. 1, the excrement disposal bag 1 used in the portable toilet set of the present embodiment is a heat seal by folding a linear thin film 2 of a linear low density polyethylene and partially heating it. However, as a premise, first, an upper surface portion 21 and a lower surface portion 22 that are elongated in the longitudinal direction are provided, and other portions are folded between the upper surface portion 21 and the lower surface portion 22 in a plurality of bellows-like shape. Laminate. This saddle-like (bellows-like) saddle-like portion 23 is about 7.5 cm away from the center line 24 in the longitudinal direction (the length of one saddle-like portion is 15 cm). As shown, it is folded to form three layers of bowl-shaped portions 23a, 23b, 23c. That is, the three hook-shaped portions 23a, 23b, and 23c are folded inward from both outer sides.
Accordingly, as can be seen from FIG. 1 and FIG. 2, the eight layers of film 2 are laminated from the top to the bottom, and if this laminated film strip 3 is pressed, the thickness is theoretically 10 μm × 8 = 80 μm. In the present embodiment, the width of the upper surface portion 11 and the lower surface portion 12 is about 15 cm. Therefore, the circumference of the original cylinder is 15 cm × 8 sheets = 120 cm.
The larger the number of the bowl-shaped portions 23, the longer the circumference becomes. On the contrary, since the thickness of the laminated film band 3 increases, it is difficult to fold the product and the diameter of the cylinder is too large. The number of the parts 23 should be about 2 to 5, and preferably about 3 as in this embodiment, considering the ease of handling.

Next, as shown in FIG. 3 and FIG. 4, the laminated film strip 3 of the laminated film 2 is heated and applied in a direction perpendicular to the longitudinal direction every predetermined length in the longitudinal direction, in this embodiment every 60 cm. As the heat-bonding and heat-bonding portion 4 to be pressed, the upper side in the longitudinal direction is the bag bottom portion 12, and a perforation 41 for cutting is provided at a position located below the bag-bottom portion 12 and the heat-bonding portion 4 in the longitudinal direction. As shown in FIG. 4 and an enlarged partial perspective view of the cut end, it is separated from the perforation 41 in use, and one perforation 41 becomes the opening 11 of the next bag, and the vicinity of the heat bonding portion 4 is the bottom of the bag. 12 becomes the excrement disposal bag which exhibits roundness. Therefore, the area of the laminated film 2 in the apparent intermediate treatment is 60 cm × 15 cm.
The bottom 12 of the bag is rounded (see FIGS. 11 and 12). The bottom end of the bag is a heat-sealed heat-bonding portion 4 having a length of 15 cm, from which three folds develop on both sides, that is, Since 15/2 cm × 3 layers = 22.5 cm is developed, it does not become a pointed bag bottom but a rounded bottom, and the shape after processing becomes compact and the storage efficiency and processing efficiency are improved.

The excrement disposal bag 1 formed as described above has a volume of a square bag (folded five times) compared to a conventional excrement disposal bag having a storage volume, and has a thickness of about 1/2 for a conventional food. Since it is 10 μm equivalent to the wrap, it is about 1/3, and the weight has been 26 g in the past, but in this embodiment it can be 7 g. This contributes to the efficiency of valuable space considering that a large amount of excrement disposal bags are taken out at the time of a disaster or the like.
In addition, this heat-sealed heat-bonding portion 4 is designed in a state where the lower part of the seal line is intentionally torn, and even if 1 L of water is put into the excrement disposal bag, the seal width h (see FIG. 5) is 1 mm. If it was welded, water did not leak. The width h of this seal is about 1 mm to 5 mm and has good sealing properties and is easy to handle.

  The characteristics of this thin film are that it is a bag with a thickness of about 5 to 15 μm, and it does not break even when water is stored, and has strength (Shulen burst strength) and flexibility (tensile modulus). It may be folded or thin, and even if the laminated film strip 3 is bonded by heat sealing, no hole is formed (heat sealing strength). In addition, the thickness of the thin film of linear low density polyethylene (LLDPE) is 5 μm to 15 μm. If it is thinner than 5 μm, the strength is weak and easily broken, and if it is thicker than 15 μm, the product is bulky and difficult to handle. This is because it is as inconvenient as that of the polyethylene film, and a thickness of 10 μm is preferable.

Next, the case where the excrement disposal bag 1 described above is used with a portable toilet set will be described.
The excrement disposal bag 1 of the present embodiment is about 6.5 cm × 7.5 cm and is 7 g in weight when folded five times, but is a portable toilet set 5 as shown in FIG. Even if one bag of 8 g of the coagulant 7 is combined, it is 15 g.
One of the features of this portable toilet set 5 is that the coagulant 7 contained in a water-soluble 7 cm × 7 cm bag 611 as shown in FIG. Fold it inside the center, put it in a 13cm x 8cm instruction manual 7, and enclose it in a watertight sealing bag 631 of 4cm x 2cm with hand-washing water 8 and finally put it in the set packing bag 51 One set. The bag for hand-washing water preferably has a width of 3 to 5 cm and a length of 1.5 to 3 cm from the viewpoint of compactness.

Here, the area of the laminated film 2 in the intermediate treatment is 60 cm × 15 cm. The excrement disposal bag 1 is wrapped with the water-soluble bag 611 of the coagulant 6 and the hand washing water 8 is sandwiched between the instructions for use 7. A procedure for packing the sealed one and finally packing it in a set packing bag 51 of a transparent or translucent film will be described with reference to FIGS.
First, FIG. 7 (a): folded in half in the longitudinal direction to 30cm × 15cm, and placed a coagulant at a position 3/4 from the right, FIG. a): The right half is folded in half, FIG. 8 (b): The left side is folded in the coagulant, FIG. 8 (c): Further folded in half, and FIG. 8 (d): The lower half is folded upward. The folded film containing the coagulant is sandwiched between the instruction manual 7 folded in half as shown in FIG.
FIG. 9 (g): The hand-washing water seal 81 is packed together in the set packing bag 51 to complete.
The final size is 8cm in width, 7cm in length, and 0.8cm in the thickest part, and a very small three-piece set consisting of a round bottom film for excretion, coagulant for excrement and hand-washing water is constructed.

The coagulant 61 is, for example, as described in the above-mentioned Patent Document 3, and in the present embodiment, a commercially available product as Cellulette (registered trademark) is used.
The coagulant 61 is obtained by mixing a deodorant and a coagulant in a water-soluble bag 71. The deodorizer is coconut shell activated carbon obtained by baking a coconut shell, and the coagulant is polyacrylic acid. sodium (-CH2CHCooNa ^-) is a superabsorbent polymer _n.
Therefore, if the set packaging bag 51 is put into the urine excreted in the excrement disposal bag 1, the set packaging bag 51 is immediately dissolved in the urine, and the deodorant and the coagulant are dissolved therein, thereby producing a deodorizing effect. Urine is gelled by the coagulant.
However, in the case of stool, it is only necessary to break the set packing bag 51 and shake the internal deodorant and coagulant into the stool. The coagulant absorbs moisture and hardens, and the deodorant activated carbon has a bad odor. It acts to suppress.

Here, the usage method of the portable toilet set 5 using the excrement disposal bag 1 is demonstrated along FIG. 11, FIG.
First, the set packaging bag 51 of the portable toilet set 5 is opened, the excrement disposal bag 1 is taken out, the upper opening 11 is opened, and air is introduced to expand to form a round bottom, as shown in FIG. Place the round bottom of the excrement disposal bag 1 on the bottom of the western style toilet 9, widen the opening 11 with a circumference of 120 cm and fold it to the edge of the toilet 9, and fit the excrement disposal bag 1 on the inner surface of the toilet 9 Let At this time, since the excrement disposal bag 1 has a round bottom, it fits the inner wall shape of a conventional toilet container, so that it naturally fits the inner surface of the toilet 8 together with the opening 11 having a circumference of 120 cm.
Thus, after the preparation is completed, the user sits on the toilet 9 or straddles the toilet 9 and excretes it in the excrement disposal bag 1. After the excretion, if the coagulant 61 is put into the excrement B such as urination / defecation, the use of urination and defecation is completed.
Thereafter, as shown in FIG. 12, the urination and defecation excrement C solidified in a gel form (jelly form) by absorbing the water as the coagulant becomes a small lump in about 30 seconds. Even if it is loaded, it is stable without collapsing, and it is possible to treat garbage as it is.
The excrement disposal bag 1 can be reused by opening the opening 11 again.
In this way, since the portable toilet set 5 is very small, it can be stocked in large quantities, even if the toilet does not function due to a power outage in the event of an earthquake, typhoon, flood, gust, lightning, tornado, etc. The excrement can be easily processed.

By the way, although the above-mentioned usage method assumed the broken toilet 9 which does not get out of water, if there is a small corrugated cardboard or a basin, dig a hole in a field etc., and arrange the corrugated cardboard or the basin, there, the above-mentioned toilet As in the case of 9, the round bottom of the excrement disposal bag 1 is placed on the bottom of the corrugated cardboard or basin, and if necessary, the user wears a poncho or the like and straddles the Japanese-style toilet style. .
Finally, the end of the bundled hand-washing water bag 81 may be cut by hand and the hands washed with the hand-washing water 8. The hand-washing water 8 of this example was sterilized with a pH of 11 to 12.7 obtained by dissolving scallop shells at ultra-high temperatures into 10-3μ particles (powder) and dissolving them in 1 g / 1 liter of water. It is water, and in this embodiment, it is a 1.5 cc to 2 cc sachet (liquid-tight bag). Although sterilized water having a pH of 11 to 12.7, more preferably pH 12.5 is used, it is characterized by no alcohol or chemicals, and can be rinsed with pure natural sterilized water. Norovirus, E. coli O-157, It is a colorless and transparent hand-washing sanitized water that also prevents influenza. To use, cut from the notch of the sachet, put hand-washing water into the dent of the hand, make it liquid from the nails and fingers, and rub well with both hands. If tap water etc. does not come out, you can wash your hands Even if it is not, it is possible to sterilize norovirus etc. by washing with this hand-washing water 8 having a sterilizing action, and the toilet can be used even if the water is cut off, and it is an emergency toilet that can be used outdoors.
Thus, since the portable toilet set 5 can be used outdoors, it can be used not only at the time of a disaster but also in a car with traffic congestion, a nursing care site, farm work, or a construction site.

As described above, the portable toilet set according to the embodiment of the present invention is very thin and not bulky even when the excrement disposal bag included in the set is folded, has a round bottom at the time of use, has strength, and is portable. It is convenient to handle, and even if a large amount is stocked for disasters, it does not occupy the place and can be processed as garbage.
In addition, it becomes thin even when folded in a waste disposal bag with a coagulant as the center, and even when combined with a water-soluble bag containing a coagulant or deodorant, it becomes an extremely small and lightweight portable toilet set, and is always used in homes and cars Even though it does not take up space, it has a wide range of use, such as a toilet with a broken usage, a box with an open top, and can be used outdoors. There is an advantage that even when the processing bag is discarded, it can be disposed as raw garbage or household waste, and does not take up space.
Of course, the present invention is not limited to the above-described embodiment as long as it does not impair the characteristics of the present invention. For example, the thickness of the linear low density polyethylene (LLDPE), the length of the bowl-shaped portion The number of bowl-shaped portions is not limited to the examples, and the deodorant may be other deodorant other than coconut shell activated carbon, and the coagulant may be another coagulant other than sodium polyacrylate.
