Description

[Technical Field]

[0001] The present invention relates to a portable toilet that is useful primarily in emergencies such as disasters. [Background technology]

[0002] The applicant previously developed the "hygienic disposal storage bag" described in Patent Document 1. This has been implemented to the present day and is provided as a means of disposing of and storing items that require hygienic handling, such as used diapers. The applicant has been considering whether this technology can be applied and improved to portable toilets.

[0003] In this regard, various portable toilets are available on the market. For example, the "completely sealed toilet waste disposal bag" described in Patent Document 2 uses a nonwoven fabric on the inside and a polypropylene fabric on the outside, with the nonwoven fabric and polypropylene sheet bonded together, and an internal waste disposal sheet containing a coagulating agent containing a deodorizing and disinfecting agent primarily composed of an absorbent polymer. The center of the toilet waste disposal bag is folded and crimped into a home base-shaped bag. A removable bag with a handle is attached to the outside, and a polypropylene component and a completely odor-blocking sheet are processed into a bag shape. A polypropylene string is attached to the top of the bag and tied to completely seal the bag, completely blocking out moisture and air. The bag's opening is then tied to achieve complete sealing. The innovative tip shape and sealed waste disposal make it easy to move and dispose of waste in special situations, and it can be replaced after each use. This provides a completely sealed toilet waste disposal bag that is effective and convenient in terms of hygiene, transportation, and disposal after using the toilet.

[0005] However, the portable toilets described above could be further improved in terms of comfort and hygiene. In particular, there was a need for a portable toilet that could efficiently dispose of moisture and other waste while maintaining portability and low cost, and that could reduce the risk of unsanitary conditions for the user and those around them. Therefore, the problem to be solved by the present invention is to provide a portable toilet that can be used in a relatively hygienic and comfortable state. [Means for solving the problem]

[0006] As a means for solving the above problem, the portable toilet according to claim 1 is a portable toilet comprising an outer bag having a layer that is neither breathable nor water-permeable, an inner bag that is water-permeable and breathable between the inside and outside of the inner bag, a first opening connected to the outer bag through which a user puts one of their legs when putting it on, a second opening connected to the outer bag through which the user puts the other leg, a fitting stabilizing means that prevents the outer bag from slipping down while the user is wearing it, and a sealing means that prevents leakage from the outer bag to the outside, wherein the outer bag and the inner bag are joined near the opening of the outer bag and near the opening of the inner bag to form a double-bag state, and is configured to create a space outside the inner bag and inside the outer bag where functional material for hygienic purposes can be placed.

[0007] The portable toilet according to claim 2 is the portable toilet according to claim 1, characterized in that the attachment stabilizing means for preventing the toilet from slipping off while being worn by the user is a string, and the string also functions as a sealing means for preventing leakage from the outer bag to the outside.

[Figure 2] FIG. 1 is a front view showing the portable toilet of the embodiment in use. [Figure 3] FIG. 1 is a left side view showing the portable toilet of the embodiment in use. [Figure 4] FIG. 2 is a diagram showing the portable toilet of the embodiment in a sealed state. DETAILED DESCRIPTION OF THE INVENTION

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments. FIG. 1 is a front view of the portable toilet of the embodiment, showing the structure inside the outer bag. The outer bag 10 is a single layer made of polyethylene, which provides a layer that is neither breathable nor water-permeable. This also makes it relatively noise-resistant and scratch-resistant. It is black in color to prevent dirt from standing out. The top of the illustration shows the opening of the outer bag, which is a typical bag without a three-dimensional shape. Note that when referring to "top," the up-down direction refers to the direction as seen by the wearer. Similarly, the front-to-back and left-to-right directions refer to the direction as seen by the wearer. In other words, the head of a standing wearer is considered to be the up direction, the feet are considered to be the down direction, the chest is considered to be the forward direction, the back is considered to be the backward direction, the right hand side is considered to be the right direction, and the left hand side is considered to be the left direction.

[0011] The outer pouch has openings 11 at the top left and top right, and since the portable toilet in this embodiment does not have a front or back, any one opening is designated as a first opening connected to the outer pouch through which the user passes one of their legs when wearing the toilet. The other opening is designated as a second opening connected to the outer pouch through which the user passes the other leg. The size of these openings should be larger than the thickness of the legs of the intended user, and they should be designed so that they function adequately as openings for the legs, such as being able to withstand slight expansion without breaking. If necessary, it is advisable to consider the material and thickness and reinforce them with tape, etc.

[0012] Two covering parts 12 are formed by extending the upper part of the outer bag, one at the front and one at the back, so that they can be sandwiched between the openings 11 for the feet. Having two covering parts 12, one at the front and one at the back, allows for some degree of shifting to be accommodated, and also functions as a measure against shifting caused by urine in the front and by wet feces or when bending over or squatting in the back. The outer bag is further provided with an adhesive portion 13 for narrowing the inner space of the outer bag downward.

[0013] The inner bag 20 is a single layer made of a water-permeable and breathable nonwoven fabric. The top of the figure represents the opening of the inner bag, and it does not have a particularly three-dimensional shape. Its shape tapers downward. The outer bag 10 and inner bag 20 are joined near the outer bag opening and the inner bag opening, forming a double-bag structure, with the hygienic treatment functional material 60 already placed inside the outer bag. The inner bag is generally smaller than the internal space of the outer bag, but the width of this joint is the same for the outer and inner bags. In this embodiment, the gap between the inner and outer bags, other than the width, is approximately 3 to 5 cm. This creates a space 40 outside the inner bag that can accommodate the hygienic treatment functional material 60. Furthermore, no means is provided for the movement of solids between the space 40 outside the inner bag and the outside. The latter has the effect of preventing leakage and the like even if the container is stored in a slightly improper orientation or shaken during transportation, from before use to after use.

[0014] By configuring the outer bag, the inner bag, or both of them so that they taper downwards, it is possible to prevent the functional material 60 from being unevenly distributed with its target, and it is expected that the function can be exerted effectively. The functional material 60 for sanitary treatment that is placed inside the outer bag is a gel that disinfects and absorbs water. Regardless of whether or not direct measures against bacteria are taken, removing moisture from feces can be expected to have the effect of inhibiting the progression of putrefaction and preventing the rise of odors.

[0015] The space 40 outside the inner bag but inside the outer bag can not only be used to place the sanitary functional material 60, but can also function as a space to retain moisture that has been removed from the feces and leaked out of the inner bag. It is desirable that the retention force be due to the water absorption function of the sanitary functional material 60, but even if moisture exceeds this capacity, the existence of this space can be expected to have the effect of preventing the progression of decay due to moisture in the feces and preventing odors that leak out and rise without passing through the inner bag.

[0016] Regarding moisture management, the capacity and size of functional materials for hygienic management, including water absorption, are designed while balancing portability and cost, but generally, portable toilets have an upper limit to the amount of moisture and feces they can handle, and unless this limit is exceeded, they cannot be used hygienically and comfortably. However, with this invention, the range of this range can be improved. In other words, the functional materials and storage capacity of the toilet can be used efficiently, and even if there is a slight excess of moisture, most of it will escape from the inner bag, reducing the progression of decay and the rise of odors from the opening of the bag. As a result, it is possible to achieve a relatively excellent hygienic condition.

[0017] Inner bag 20 has adhesive 21 as backflow prevention means, which is formed by fusing the front and back of the inner bag. The shape of the adhesive is such that it allows water to flow from top to bottom inside the inner bag, but prevents backflow to a certain extent. Note that the method of providing the adhesive as backflow prevention means is not limited to this, and adhesives other than fusing may be used, and even if the shape is simply shaped like a sieve (e.g., a dashed line), water will fall due to gravity when using the toilet, and a certain degree of backflow prevention power can be expected after sealing.

[0018] Furthermore, in this embodiment, a simple hygienic functional material 50 with relatively weak water absorption is placed inside the inner bag 20 to adjust the absorbency. This can be added later for flexible use. This is particularly effective when the stool is very moist. The hygienic functional material 50 in this embodiment was selected, shaped, and sized to provide effective backflow prevention, and was placed before the backflow prevention device was installed. This can also be achieved by using a sheet or other material that is layered on top of the bag and glued to prevent backflow. The inner bag itself, made of nonwoven fabric, already has a certain degree of water absorption, and this can be achieved by adjusting the thickness, number of layers, and processing to impart functionality. However, in principle, it is desirable for moisture to escape from the inner bag as much as possible. It is more desirable to prioritize the use of gravity and the water absorption function of the functional material 60, and to adjust, design, and use the inner bag so that the water absorption function is also exhibited to a moderate extent.

[0019] The covering portion 12 can be made to function more effectively by configuring the inner bag 20 to extend upward (as is the case to some extent in the embodiment), or by attaching a separate nonwoven fabric or sheet, etc., and by devising a method of adhering it to the outer bag 10 and covering portion 12 (for example, by adjusting the range of use of fusion depending on at what point the water absorption function of the inner bag itself should be exerted). Furthermore, the design may be such that moisture generated at an unexpectedly high position is guided into the inner bag rather than flowing toward the feet. Next, the string 30, which acts as a means for stabilizing the shoe and prevents it from slipping off while the user is wearing it, is made of polypropylene and is fixed to the top of the opening 11 through which one foot is passed, at a point where the total length of the string is divided into approximately 3:1 parts. The method of use will be described later, but stable attachment leads to less soiling and hygienic use. The user puts it on by putting it through their feet, and it is equipped with a string as a means of stabilizing the fit to prevent it from slipping off while the user is wearing it, which has the effect of reducing the risk of unsanitary conditions for the user and those around them.

[0020] Figure 2 is a front view of the portable toilet of the embodiment in use, and Figure 3 is a left side view of the same. Note that the user's posture in both figures is not the same. First, the user should remove any clothing that will get in the way when using the portable toilet. It is recommended that at least all clothing covering the lower body be removed. Shoes and other clothing may not need to be removed depending on the configuration (size, strength, etc.) of the opening 11 through which the feet pass. Next, the user puts his / her feet through the leg openings 11 and puts on the portable toilet. Furthermore, the long side of the string 30 is passed around from the back and through the opening 11 for the left foot shown in Fig. 3, and this and the short side of the string 30 are tied in front of the covering part 12 corresponding to the front side shown in Fig. 2. The covering part 12 corresponding to the back side shown in Fig. 3 is also sandwiched inside the string, which makes the garment more stable when worn. The user relieves themselves while standing, bending, or squatting, ensuring that feces can be expected to be collected into the portable toilet bag (shown as outer bag 10). After using the toilet, the user can remove all or part of the portable toilet, wipe the body or other necessary areas with separately prepared paper or the like, clean up any dirt, and dispose of the resulting waste inside the portable toilet (in the outer bag 10 in the figure, or more specifically, into the inner bag). At this time, additional functional material 50 can be added if necessary.

[0021] FIG. 4 is a diagram showing the portable toilet of the embodiment after sealing. In the embodiment, the string 30 is used as a means for stabilizing the attachment to prevent the device from slipping off while being worn by the user, but this string 30 is also used as a sealing means for preventing leakage from the outer bag to the outside. After removal, fold the cover 12 into the outer bag 10, then fold it back so that the opening of the outer bag is closed, and preferably roll it down. At this point, for convenience in storage until further disposal, it is advisable to remove the air from the inside to reduce the bulk. Also, since the portable toilet in the embodiment does not have a three-dimensional structure, it may be tempting to fold it so that the left and right sides are separated, but if you expand it as much as possible in the front and back directions to make it three-dimensional and reduce the width in the left and right directions, it is thought that it will be easier to avoid waste and unevenness in the effectiveness of the functional material. The opening is further sealed with string 30. Preferably, the string is wrapped around four or five times for maximum security. This provides a tight seal that prevents solids, liquids, and gases from leaking out of the outer bag. It is a good idea to place this in a separate bag that can block air and water and can also be sealed. Furthermore, if the set includes the aforementioned "sanitary disposal storage bag" that can store about 30 of these, the storage period between use and disposal can be kept hygienic. The above describes a form for implementing the invention based on one example of implementation, but this is merely an example, and the content of the implementation means is not limited to this, and it goes without saying that modifications can be made within the scope of the spirit of the invention.

[0022] Furthermore, in explaining the prior art, the applicant's past technology has been described, but this is merely for reference and is not intended to be binding. For example, it goes without saying that the structure of squeezing the inner bag is not an essential requirement of the present invention. Regarding the inner bag, which is commonly described in both documents, its form and presence or absence should be understood in accordance with the spirit of each. For example, even if it is not completely structured as a bag, but has gaps or the like that allow solid matter to pass between the space outside the inner bag and the space inside the outer bag, it is considered possible to have a structure that does not violate a certain spirit.

[0023] In the embodiment, the outer bag 10 is black, but the effect of not making dirt conspicuous may still be achieved even if other colors are used. Other variations are possible, such as prioritizing design, or selecting a color such as white that makes dirt more conspicuous and contributes to hygiene risk management, or making the inside of the bag visible for the health management of the user, for example, by making part of the outer bag transparent. The outer bag material can be polypropylene, etc., and materials that have been additionally processed to prevent air and water from passing through can also be selected. It is even more desirable if the construction can take into consideration damage and holes caused by unintentional contact. The outer bag may have a three-dimensional structure. This may improve ease of use and may also help prevent the outer bag from being folded when sealing after use, resulting in waste and unevenness in the effectiveness of the functional material. However, adding a gusset may make it easier for grooves and ridges to form, which may result in waste and unevenness in the effectiveness of the functional material, so it may be possible to add a bottom plate, for example.

[0024] The inner bag 20 may be made of woven fabric or mesh material, which is suitable for the purpose of allowing air and water to pass through. Depending on the material of the inner bag, it may be possible to expect sound-deadening effects, improved softness to the touch, prevention of dirt splashing, and a lid effect when pleats are formed. Pleats may also be intentionally provided. The adhesive portion 21 as the backflow prevention means may be formed by a means other than fusion, may be formed by overlapping the outer bag, or may be provided in a part other than the inner bag. It is desirable that the pleats and backflow prevention means are of a degree that does not interfere with the containment of feces (movement downward within the inner bag due to gravity). The functional materials used can be in a variety of forms, including gel, pellets, pulp, and sponge. In addition, even when the material itself, such as the bag body, is treated, the functions that can be exerted include water absorption, antibacterial measures such as sterilization, deodorization, as well as pH adjustment and fragrance emission.

[0025] The openings for the feet can be made of rubber, so that hands can be inserted to wipe off dirt from the body before undoing the garment after use. Also, belts, strings, etc. can be used. To prevent wet waste from flowing down towards the feet, which is particularly important when using the bag while standing, a moisture guide can be provided by attaching a Y-shaped nonwoven fabric near the foot opening. The V part of the Y can temporarily absorb any moisture that may be flowing down towards the feet, and the I part that follows can guide the moisture towards the inner bag. This is expected to have the effect of reducing contact and friction with the foot opening, which is in relatively strong contact, and also to reinforce this part of the outer bag, which is subject to force and is prone to tearing. In order to obtain the effect of reinforcing the parts that are prone to tearing, tape or the like may be used to reinforce the vicinity of the opening through which the foot passes, other parts, or even from the outside of the outer bag. The configuration of the fastening means that prevents the string 30 from slipping off while the user is wearing it, such as whether or not to fasten it somewhere beforehand, can be varied in various ways, taking into consideration factors such as the stability of the fit, ease of putting it on, and ease of removing it after use. When hanging the opening for inserting the feet, in addition to fastening it and threading the string through the opening, it is also possible to provide a loop at the top, like when threading a belt. It is also possible to simply make a hole or slit and thread the string through it, but if it is prone to tearing, it is a good idea to reinforce it with tape or something similar.

[0026] The front and back covers may also be configured to use strings, in addition to clamping. If a single string is pre-attached in one location, securing it to the top of the back cover at about half of its length will make it more comfortable to wear. However, it may be desirable to reinforce this to prevent it from tearing. In any case, depending on the configuration adopted, it is recommended that users be informed of which is recommended first: putting the foot through or using the string. Other than strings, other methods of securing the glove include belts, elastic bands, suspenders, adhesive tape, hook-and-loop fasteners on upper body clothing, and the ability to freely attach and detach the front and back like hakama. These methods may be used in combination or as substitutes. These methods may also be used only to stabilize part of the glove.

[0027] It is effective to use the string 30 as a sealing means after defecation, but it is also possible to provide another sealing means in addition to or instead of this, such as adhesive tape. It is also possible to remove unnecessary parts of the outer bag that have adhesive that allows it to taper downwards. This requires more manufacturing effort, but it makes it possible to reduce weight and space. Alternatively, it is also possible to use an outer bag that is designed to taper from the beginning. Conversely, it is also possible to provide adhesive parts on the inner bag that allow it to taper downwards. Since the contents are not flushed down the toilet after use, non-water-soluble paper, wet tissue, cloth, etc. can be used to wipe off dirt. These may also be provided as a set. [Industrial Applicability]

[0028] This portable toilet is convenient for use when out and about, such as during disasters, mountain climbing, or long-distance car trips. It can also be used in emergency situations, such as to deal with unexpected vomiting. Furthermore, when it comes to production, especially if the bags can be produced or procured, the fact that they can be used with a little effort makes this a highly applicable invention.
