The perspective view which cut | disconnected the film belt of the state of FIG. 3 from the perforation, and was used as the excrement disposal bag, The expanded partial perspective view of the A section of FIG. [Table 1] figure of the performance of linear low density polyethylene used in the examples, Sectional drawing of the portable toilet set of the Example of this invention, Explanatory drawing explaining the usage method in the toilet of the excrement disposal bag of the Example of this invention, and a portable toilet set, It is explanatory drawing explaining the processing method of the excrement disposal bag after excretion in FIG.

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. The excrement disposal bag in which the bottom of the bag is rounded during use and the portable toilet set using the bag are heat-sealed to achieve the initial purpose.
Hereinafter, preferred embodiments of the excrement disposal bag and portable toilet set of the present invention will be described 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 in which a repeating unit of ethylene and a small amount of α-olefin are copolymerized. In JIS 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 of the present embodiment folds the linear thin film 2 made of linear low density polyethylene and partially heats and heat seals. As described above, the upper surface portion 21 and the lower surface portion 22 which are elongated in the longitudinal direction are provided, and the other portions are folded and laminated between the upper surface portion 21 and the lower surface portion 22 in a plurality of bellows. 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, so the circumference of the original cylinder is 15 cm × 8 sheets = 120 cm.
Note that the greater the number of the bowl-shaped portions 23, the greater the length of the circumference, but conversely, since the thickness of the laminated film band 3 increases, the product is difficult to fold and the diameter of the cylinder is too large. The number of the shape portions 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 part 4 to be pressed, the upper side in the longitudinal direction is the bag bottom part 12, and a perforation 5 for cutting is provided at a position located on the lower side in the longitudinal direction of the bag bottom part 12 and the heat-bonding part 4. As shown in FIG. 4 and an enlarged partial perspective view of the cut end, it is separated from the perforation 5 in use, and one perforation 5 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.
The bottom 12 of the bag is rounded (see FIGS. 8 and 9). The bottom end of the bag is a heat-sealed heat-bonding portion 4 having a length of 15 cm, and three folds are developed on both sides from the bottom, ie, 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.

The test results are shown in the following [Table 1] in FIG.
[Table 1] of this test result is a 10 μm thick bag of linear low-density polyethylene (LLDPE) used in this example, and the test method for Schuleen burst strength conforms to JIS P8112: 2008 I did it.
Also, the test methods for tensile modulus are JIS K7161; 1994 (Plastics-Test methods for tensile properties Part 1: General), JIS K7127; 1999 (Plastics-Test methods for tensile properties Part 3: Films and sheets (Test conditions).
The test speed was 1 mm / min, the gripping tool distance was 100 mm, and an autograph AG-X plas 5kn (manufactured by Shimadzu Corporation) was used as the measuring machine.
The test method of heat seal strength is performed in accordance with JIS Z 1711: 1994 (polyethylene film), and the test conditions are 8 sheets (8 laminated in this embodiment) and 1 and 7 film portions. Each was attached to a gripper of a testing machine so as not to sag, and a test was performed with a hole having no hole outside and a hole having a hole outside the heat seal portion.
The test piece was a strip-shaped test piece having a width of 15 mm, the test speed was mm / mim, and the measuring machine used was Autograph AG-IS 5kN (manufactured by Shimadzu Corporation).

Next, when using the excrement disposal bag 1 mentioned above as a toilet, and a portable toilet set are demonstrated.
As described above, the excrement disposal bag 1 of the present embodiment is 10 cm × 8 cm when folded five times and is 7 g in weight, but is a portable toilet set 6 as shown in FIG. Even if one bag of 8 g of deodorant coagulant 7 is combined with this, it is 15 g.
In this portable toilet set 6, the excrement disposal bag 1 is folded and the deodorizing coagulant 7 is placed in a packing bag 61 to form one set.
The deodorant coagulant 7 is, for example, as described in the above-mentioned Patent Document 3, and in the present embodiment, the one commercially available as Cellulette (registered trademark) is used.
The deodorant coagulant 7 is a water-soluble bag 71 in which a deodorant and a coagulant are mixed. The deodorant is coconut shell activated carbon obtained by baking a coconut shell. sodium acrylate (-CH2CHCooNa ^-) is a superabsorbent polymer _n.
Therefore, if the entire packaging bag 61 is put into the urine excreted in the excrement disposal bag 1, the packaging bag 61 immediately dissolves in the urine, and the deodorant and the coagulant therein dissolve and exert a deodorizing effect. As a result, urine gels.
However, in the case of stool, it is only necessary to break the packing bag 61 and shake the internal deodorant and coagulant into the stool. The coagulant absorbs moisture and hardens, and the deodorant activated carbon suppresses malodor. Works.

Here, along with FIG. 8, FIG. 9, the usage method of the portable toilet set 6 using the excrement disposal bag 1 is demonstrated.
First, the packing bag 61 of the portable toilet set 6 is opened, the excrement disposal bag 1 is taken out, the upper opening 11 is opened, and air is introduced so as to form a round bottom, as shown in FIG. Place the round bottom of the excrement disposal bag 1 on the bottom of the style toilet 8, widen the opening 11 around the circumference of 120 cm and fold it to the edge of the toilet 8, and fit the excrement disposal bag 1 to the inner surface of the toilet 8 . At this time, since the excreta disposal bag 1 has a round bottom, it fits the shape of the inner wall of a conventional toilet container, and thus fits naturally with 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 in the toilet or straddles the toilet and excretes it in the excrement disposal bag 1. And after the excretion, if the deodorizing coagulant 7 is put into the excrement B such as urination / defecation, the use of urination and defecation is completed.
Thereafter, as shown in FIG. 9, the urination and defecation excrement C solidified in a gel form (jelly form) by absorbing the water as a 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 6 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 Similarly to the case of 8, the round bottom of the excrement disposal bag 1 is placed on the bottom of the cardboard or the basin, and if necessary, the user may wear a poncho or the like and use it across the Japanese-style toilet style.
Thus, since the portable toilet set 6 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, agricultural work, or a construction site.

As described above, the excrement disposal bag according to the embodiment of the present invention is thin even when folded, the bottom portion is rounded when used, and it is strong and convenient to carry and handle. It is possible not to occupy and to treat the waste as garbage.
In addition, the portable toilet set of the embodiment of the present invention is thin even when the excrement disposal bag is folded, and even if combined with a water-soluble bag containing a coagulant and a deodorant, the portable toilet set is extremely small and lightweight. It is ideal for stockpiling and excrement in a wide variety of places, such as toilets that do not take up space even if they are regularly used in homes and automobiles, use forms are broken, boxes that are open at the top, and can be used outdoors. Disposal of the treatment bag containing the waste can be done as raw garbage or household waste, and there is an advantage that the excrement is solidified compactly and does not take up a place.
It should be noted that 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 other coagulant other than sodium polyacrylate. Of course it is good.
