Description

Urine bag

Technical Field

The invention relates to the field of medical equipment, the field of daily necessities and the field of domestic sewage treatment. In particular, the present invention relates to a novel urine bag.

Background

The urine bag has wide use scenes, for example, for patients or old people who are inconvenient to get out of bed, the urine bag is used for urination on the bed or at the bedside, so that the burden of the patients, the old people or nursing staff can be relieved; for drivers who drive vehicles for long distances but cannot reach service stations quickly, the urine bag can be used for urinating in the vehicles, and great convenience can be provided. The urine bag may also be used in a variety of other situations where a restroom is not present or difficult to reach or use.

The urine bag of prior art mostly adopts split type urine storage bag and connects the urine ware, connects the urine ware to adopt rubber materials to mould plastics to form usually, and its upper side opening is used for receiving urine from the human body, and the downside opening is connected to the urine storage bag. Such a structure has many problems, for example, the urine storage bag and the urine receptacle need to be separately stored, and it takes time to perform installation operation when in use, which is inconvenient to operate; the structure of the interface between the storage bag and the urine receiver is complex, and the storage bag can easily fall off if the storage bag is not installed properly; the rubber urine receiver has large volume and is inconvenient to store and transport; the rubber urine receiver has higher cost, and users usually choose to use the rubber urine receiver for many times, and the urine receiver is stained with urine, can generate peculiar smell and is easy to breed bacteria, and is inconvenient to clean; the post-treatment of the urine bag is inconvenient and not environment-friendly.

Therefore, it is desirable to obtain a urine bag which is low in cost, convenient to operate, clean and sanitary, and environment-friendly to post-treat.

Disclosure of Invention

The present invention is directed to solving at least one problem posed by the prior art. More precisely, the invention aims to provide a urine bag which has low cost, convenient operation, cleanness, sanitation, post-treatment and environmental protection.

To this end, the invention provides a urine bag comprising: a receiving portion for receiving urine; a receiving portion having a hollow tubular shape and having an upper opening and a lower opening, the lower opening of the receiving portion being disposed inside the accommodating portion, and a backflow prevention portion being formed near the lower opening of the receiving portion; a hardening portion adapted to be received in the access portion, the hardening portion being harder in material than the access portion; wherein the urine bag has two forms which can be switched with each other: in the pressing mode, two sheets near the upper opening of the receiving part are close to each other, so that the upper opening is kept closed; in the deployed configuration, the two sheets near the upper opening of the access portion are moved away from each other by an external force applied by the hardened portion, causing the upper opening to become open.

The urine bag according to this solution has at least the following advantages:

the containing part and the receiving part form an integrated urine bag, which is convenient to transport and store, does not need to be assembled when in use and is quick and convenient to use compared with a split structure in the prior art;

in the pressed configuration (i.e. before use or after use), the urine bag is in the form of a sheet, with a small thickness dimension, saving bulk;

the stiffening portion stiffens the receiving portion, whereby in the deployed configuration (i.e. the in-use configuration), the stiffening portion supports the upper opening of the receiving portion to become open, preventing the receiving portion from bending and deforming, facilitating the user to carry the urine bag for urination, greatly improving the ease of use, and furthermore, the stiffening portion braces the receiving portion so that urine can freely enter the receiving portion;

in the pressed state, a backflow prevention part is formed near the lower opening of the receiving part, and when two opposite inner side surfaces of the backflow prevention part are attached to each other, a fluid path from the lower opening to the upper opening can be closed, so that urine is effectively prevented from flowing outwards, and the environment is prevented from being polluted.

In some embodiments, the stiffening portion is attached to the access portion and has opposing first and second sheets; in the pressing mode, the first sheet material and the second sheet material of the hardening part are kept close to each other under the action of no external force, at the moment, the hardening part forms a sheet shape, and the upper opening of the receiving part is kept closed; in the unfolding state, the first sheet and the second sheet of the hardening part are far away from each other under the action of external force, the hardening part forms a tubular shape, and the opening on the access part is opened; and, a length between the lower edge of the hardened portion to the lower opening of the access portion is greater than 1/4 and less than 1/2 of a total length between the upper opening and the lower opening of the access portion.

The advantages according to this solution are at least:

when the lower edge of the stiffening portion is closed, since the stiffening portion is stiffer than the backflow prevention portion, the stiffening portion is less likely to unfold under the reverse impact of urine, preventing the backflow prevention portion from crossing the lower edge of the stiffening portion from the inside of the receiving portion towards the upper opening (i.e. preventing "back-up phenomenon"), preventing accidental urine spillage;

the inventors have experimentally found that a length between the lower edge of the stiffening portion and the lower opening of the access portion greater than 1/4 and less than 1/2 of the total length between the upper and lower openings of the access portion is very advantageous. If the length between the lower edge of the hardened portion and the lower opening of the take-off portion is less than 1/4 of the total length of the take-off portion, the material of the take-off portion between the lower edge of the hardened portion and the lower opening of the take-off portion is too little to form an effective backflow prevention portion; if the length between the lower edge of sclerosis portion to the lower opening of takeout portion is greater than 1/2 of the total length of takeout portion, the material of takeout portion between the lower edge of sclerosis portion to the lower opening of takeout portion is too much, results in when expanding sclerosis portion, and the lower opening of takeout portion still can keep closing, prevents that the urine is unobstructed to get into the portion of holding, and correspondingly, the material of takeout portion between the lower edge of sclerosis portion to the upper opening of takeout portion is too little, can't form effective and reliable hand grip portion through sclerosis portion, and the use experience is not good.

In some embodiments, a portion of the access portion is located inside the receptacle, and the upper opening of the access portion is located outside the receptacle.

In some embodiments, the entirety of the access portion is located inside the receiving portion, and the upper opening of the access portion is also located inside the receiving portion.

In some embodiments, the access portion is an integral inverted conical hollow tubular structure.

In some embodiments, the portion of takeing includes the last portion of takeing and the portion of takeing down of components of a whole that can function independently, it is connected to go up the portion of takeing to connect to the portion of holding, it has the tubulose inner chamber to go up the portion of takeing, and the surface laminating of sclerosis portion is fixed to the internal surface of the portion of takeing down, the portion of takeing down is the tubular structure, the upside opening of the portion of takeing down is attached to the lower limb of sclerosis portion, the lower limb distance of sclerosis portion the lower opening of the portion of takedown is certain distance to the messenger forms the anti-backflow portion near the lower opening of the portion of takedown.

In some embodiments, a receiving piece is arranged on the outer side of the accommodating part, and a receiving bag is formed between the receiving piece and the outer side of the accommodating part; the urine bag is configured to be foldable around a folding part so that the upper opening of the receiving part enters the inner part of the containing bag.

In the scheme, after the urine bag is used for receiving urine, the receiving part which is stained with the urine can be closed, then the receiving part is turned over and placed into the containing bag, and the containing bag can prevent foreign matters generated at the receiving part from being diffused to the surrounding environment, so that the use experience is improved; moreover, because the receiving part is folded, the inner side surface of the receiving part at the folded part can be tightly attached, and the risk of urine leakage can be further reduced.

In some embodiments, the location of the flap is higher than or equal to the location of the lower opening and lower than or equal to the location of the lower edge of the hardened portion.

The inventor finds that the position arrangement of the turnover part is very beneficial through experimental tests. On one hand, the position of the folding part is higher than or equal to the position of the lower opening, so that the position of the folding part is adjacent to or above the lower opening, and the folding operation can further press the lower opening or above the lower opening, so as to further ensure that urine cannot pass through the lower opening and leak out; on the other hand, if the position of the folded portion is higher than the position of the lower edge of the hardened portion, the hardened portion needs to be folded during the folding process, the resistance of the folding operation is increased, and the hardened portion is hard, so that the risk of damaging the urine bag exists.

In some embodiments, the lower side of the containing part is provided with an upward-turning piece which can be turned upwards to form a containing bag with the outer side of the containing part; the urine bag is configured to be foldable around a folding part so that the upper opening of the receiving part enters the inner part of the containing bag.

In some embodiments, the pouch has an adhesive portion that adheres the receiving portion to fix the receiving portion with respect to the receiving sheet.

In this aspect, the adhesive portion can secure the receiving portion relative to the storage bag to prevent the receiving portion from accidentally coming off.

In some embodiments, the adhesive portion forms a seal that seals the portion of the access portion located within the pouch from the external environment.

In this aspect, the sealing portion separates the inside and the outside of the storage bag in a gas-tight and liquid-tight manner, and the foreign matter generated at the receiving portion can be further prevented from being diffused into the surrounding environment.

In some embodiments, the pouch may contain paper towels.

In some embodiments, the access portion is in the shape of an inverted conical tube with an upper opening larger than a lower opening.

In some embodiments, the upper edge of the stiffening portion extends beyond the upper opening of the access portion, and the upper edge of the stiffening portion has a rounded interface formed by eversion.

According to the scheme, the circular interface of the hardening part can be comfortably attached to the body, the skin is prevented from being cut, and the use experience is improved.

In some embodiments, the upper edge of the stiffening portion is lower than the upper opening of the take-up portion, and the upper edge of the take-up portion has a rounded seam formed by eversion.

According to the scheme, the round interface of the access part can be comfortably attached to the body, the skin is prevented from being cut, and the use experience is improved.

In some embodiments, a urine absorbing material is disposed within the receptacle.

According to the scheme, the urine absorbing material can convert urine into a colloidal state or a solid state, and the urine is prevented from leaking to pollute the environment when the urine bag is accidentally punctured or squeezed.

In some embodiments, the lower side of the receptacle is provided with a normally closed valve which, when opened, drains urine from the receptacle.

According to this aspect, the urine can be discharged by operating the valve, so that the urine bag can be discarded in a urine-free state or reused.

In some embodiments, the material of the stiffening portion is paper, plastic, rubber, fabric or a combination thereof, and the material of the receiving portion is paper, plastic, rubber, fabric or a combination thereof; the material of the hardened portion has a bending deformation resistance superior to that of the material of the take-up portion.

In some embodiments, the receiving portion, and the stiffening portion are made of biodegradable materials.

According to the scheme, after the urine bag is used for receiving urine, the urine bag can be placed in the field, after a period of time, all materials of the urine bag are biodegraded and disappear, and the urine can be used as organic fertilizer to enter soil, so that the convenient and environment-friendly post-treatment of the urine bag is realized, and the treatment of the domestic sewage, namely the urine, is realized in a very environment-friendly mode.

In some embodiments, the stiffening portion is an integral conical cylindrical structure disposed inside or outside the access portion.

In some embodiments, the stiffening portion is a separate first sheet and second sheet, the first sheet being disposed inside or outside the access portion and the second sheet being disposed inside or outside the access portion.

In some embodiments, the outer surface of the first sheet is secured to the first inner surface of the access portion and the outer surface of the second sheet is secured to the second inner surface of the access portion.

In some embodiments, the access portion is hourglass shaped having a first portion outside the containment bag that is reverse tapered for receiving the hardened portion therein and a second portion inside the containment bag that is tapered for forming the backflow prevention portion.

Fig. 1 shows an exploded view of parts of a urine bag 10 according to an embodiment of the present invention, and fig. 2 and 3 show assembled views of the parts of the urine bag 10. As best shown in fig. 3, the urine bag 10 of the present invention mainly includes a containing portion 100, an accessing portion 200, and a hardened portion 300. The receiving portion 100 is for receiving urine; the receiving portion 200 is connected to the receiving portion 100 for receiving urine into the receiving portion 100. In the illustrated embodiment, the receiving portion 200 is a hollow tube having an upper opening 201 and a lower opening 202, the upper opening 201 and the upper portion of the receiving portion 200 being disposed outside the receiving portion 100, and the lower opening 202 and the lower portion of the receiving portion 200 being disposed inside the receiving portion 100. The hardened portion 300 is attached to the upper portion of the access portion 200 for improving the resistance of the upper portion of the access portion 200 to bending deformation.

Fig. 1 shows a receptacle 100, which is embodied as a bag made of a soft material such as paper, plastic, rubber, fabric, or a combination thereof. As shown in fig. 1, one example of the receiving portion 100 is a plastic bag having a substantially rectangular outline, but the present invention is not limited thereto, and other shapes of the plastic bag are possible as the receiving portion 100 as long as it can receive a certain volume of urine without leakage. Preferably, the receiving portion 100 has a generally dumbbell-shaped (or called hourglass-shaped) profile. Further, the receiving portion 100 may be transparent, translucent, or opaque.

Fig. 1 shows an access portion 200 for accessing urine into the receiving portion 100. The receiving portion 200 is a hollow tubular structure, preferably, a hollow tube of an inverted cone shape as shown in fig. 1. Other forms of hollow tube, such as a cylindrical hollow tube, may also be employed in other examples not shown. When the upper opening 201 of the receiving portion 200 is opened to the outside of the urine bag, it can be used to receive urine from a user; when the lower opening 202 of the receiving portion 200 is opened to the inside of the urine bag, it is possible to allow the received urine to flow into the inside of the containing portion 100 of the urine bag smoothly. The receiving portion 200 may also be made of a less rigid material such as paper, plastic, rubber, fabric, or a combination thereof.

Fig. 1 also shows a hardened portion 300 for attachment to the take-up portion 200, which acts to harden the take-up portion 200, improving the ability of the take-up portion 200 to resist bending deformation. In one example, the hardened portion 300 may be an inverted conical hollow tube as shown in fig. 1, which may be inserted inside the receiving portion 200, which is also an inverted conical hollow tube. Also, the outer surface of the hardened portion 300 and the inner surface of the take-up portion 200 are contoured so that they can be closely fitted to each other. The stiffening portion 300 may be made of a material such as paper, plastic, rubber, fabric, or a combination thereof, which has a greater hardness, and it should be noted that the material of the stiffening portion 300 has a bending deformation resistance/hardness that is better than the bending deformation resistance/hardness of the material of the access portion 200, so that the hardness and bending deformation resistance of the corresponding portion of the access portion 200 are enhanced after the access portion 200 and the stiffening portion 300 are attached. Although the drawings show the hardened portion as a unitary conical cylinder disposed inside the take-off portion, in other embodiments, the hardened portion may also be a unitary conical cylinder disposed outside the take-off portion; in other embodiments, the stiffening portion may also be a first and a second separate sheet, wherein the first sheet is disposed inside or outside the access portion and the second sheet is disposed inside or outside the access portion; preferably, the outer surface of the first sheet is secured to the first inner surface of the take-up portion and the outer surface of the second sheet is secured to the second inner surface of the take-up portion.

Fig. 2 is a diagram of an intermediate state of a urine bag during the assembly process according to an embodiment of the present invention. As shown in fig. 2, the hardened portion 300 of the reverse-tapered hollow tube shown in fig. 1 has been placed inside the take-up portion 200 of the reverse-tapered hollow tube; then, the two are flattened so that the two opposing sheets forming the hardened portion 300 are fitted to each other, and at least portions of the two opposing inner side surfaces of the take-up portion 200, such as the annular portion near the upper opening 201 and the annular portion near the lower opening 202, are also fitted to each other, whereby the dimension in the thickness direction (i.e., the dimension perpendicular to the sheet surface of fig. 2) of both the take-up portion 200 and the hardened portion 300 is significantly reduced, changing the entirety thereof from a tubular shape to a sheet shape. Thereafter, at least a portion of the access portion 200 is placed into the interior of the housing portion 100 through the upper opening 101 of the housing portion 100 such that the upper portion and the upper opening 201 of the access portion 200 are disposed outside the housing portion 100 and the lower portion and the lower opening 202 of the access portion 200 are disposed inside the housing portion 100.

Fig. 3 is a front view of the urine bag 10 according to the present invention, showing the urine bag 10 after the assembling process is completed. As shown by the lower chain line in fig. 3, heat sealing is performed at the opening position of the container 100 to form a weld line H, thereby closing the opening of the container 100; also, the receiving portion 100 and the receiving portion 200 are connected to each other by the heat-sealing line H. Further, as shown by the upper chain line in fig. 3, heat sealing is also performed at some position where the hardened portion 300 and the receiving portion 200 overlap, and a weld line H is formed so that the hardened portion 300 and the receiving portion 200 are connected to each other. Thus, the receiving portion 100, the receiving portion 200, and the hardened portion 300 form an integrated urine bag. It should be noted that the assembly processing manner shown in fig. 2 and 3 is only an example, and may be appropriately adjusted according to actual production requirements, for example, the receiving portion 200 and the hardening portion 300 are first heat-sealed, and then the two are partially or completely placed into the opening of the accommodating portion 100; for example, the connection portion between the receiving portion 200 and the hardened portion 300 may be a single loop, a single loop having a constant width, or a plurality of connection regions separated from each other, as long as the receiving portion 200 and the hardened portion 300 can be integrally fixed.

The use of the urine bag according to the invention will be explained below with reference to fig. 3 to 11, from which the characteristics and advantages of the urine bag according to the invention will become more apparent.

Fig. 3 shows a front view of the urine bag before use, e.g. just removed from the packaging box; fig. 8 shows a side view of the urine bag at this time. As shown, prior to use, the access portion 200 of the urine bag is in a press-fit configuration, in which the two opposing sheets of the stiffening portion 300 are pressed together such that the two opposing first and second inner sides of the access portion 200 at least partially conform to each other, and both the upper and lower openings 201, 202 remain closed. The urine bag has a small size in the thickness direction, can be conveniently stored and transported by producers, distributors, transporters and users, and has remarkable economic benefit.

Figure 4 shows a front view of the urine bag during use; fig. 9 shows a side view of the urine bag at this time. As shown in the drawings, during use, a user may apply a certain pressing force by hand at the portions of the left and right side edges of the access portion 200 in fig. 3, causing the two opposite sheets of the hardened portion 300 to be separated from each other and bringing the two previously fitted inner side surfaces of the access portion 300 to be also separated from each other, so that the access portion 300 becomes a hollow tube type. At this time, the access portion 200 is in the expanded form, and at this time, the first inner side surface and the second inner side surface of the access portion 200 are separated from each other, the upper opening 201 becomes open, and the lower opening 202 may also become open. At this time, the user may inject urine into the upper opening 201 of the receiving portion 200, the urine may be guided through the inner walls of the receiving portion 200 and the hardened portion 300, and may smoothly flow into the receiving portion 100 below through the lower opening 202 of the receiving portion 200, and the short dotted line in the figure shows the received urine U. Note that, if the hardened portion 300 is not present, since the material of the receiving portion 200 is soft and easily deformed, it is difficult for the user to hold the receiving portion 200 during receiving urine. In the urine bag of the present invention, the hardened portion 300 enhances the hardness of the upper portion of the receiving portion 200 so that it is not easily deformed, can be conveniently and reliably held by a user, and greatly improves the convenience of use. On the other hand, due to the supporting function of the hardened portion 300, the lower opening 202 of the receiving portion 200 or a portion in the vicinity thereof becomes open, allowing urine to flow smoothly therethrough without causing clogging.

Figure 5 shows a front view of the urine bag after use; fig. 10 shows a side view of the urine bag at this time. As shown in the drawings, after urine is collected using the urine bag, a user may apply a certain pressing force to the outside portions of the front and rear sides of the collecting portion 200 in fig. 4 by hand, so that the two opposite sheets of the hardened portion 300 are pressed together again, and the two previously separated inside surfaces of the collecting portion 200 are also brought into close contact with each other again, so that the collecting portion 200 becomes an internally closed sheet. At this time, the receiving portion 200 of the urine bag is returned to the press-fit state, and at this time, the opposite inner side surfaces of the receiving portion 200 are attached to each other, and both the upper opening 201 and the lower opening 202 are closed. At this time, in a region close to the lower opening 202 of the receiving portion 200, two opposing inner side surfaces and an inner side surface of the receiving portion 200 are bonded to each other, and a fluid path from the lower opening 202 to the upper opening 201 is closed, thereby forming the backflow preventing portion 204. When the orientation of the urine bag is changed (e.g., tilted or inverted), the urine U will be wrapped around the backflow prevention portion 204 and pressed, so as to prevent the urine U from leaking out through the access portion 200, and keep the urine bag clean.

In the state shown in fig. 5 and 10, the inventors have found that although the access portion 200 is already closed, a certain odor is generated due to contact with urine, which is a problem particularly when a urine bag is used in a closed space such as a vehicle. To solve this odor problem, in the urine bag of the present invention, as best shown in fig. 8, a storage sheet 102 is provided outside the containing portion 100, and a storage bag 103 is formed between the storage sheet 102 and the outside of the containing portion 100. As shown in fig. 1, the receiving sheet 102 may have a substantially rectangular shape, and is joined to the outside of the receiving portion 100 at the left, right, and lower three edge portions thereof through a heat-sealing process, while the upper edge portion is kept separated to form a pocket-like structure. The urine bag of the present invention is configured to be folded around a fold-over portion B so that the upper opening 201 of the receiving portion 200 can enter the inside of this storage bag 103. Since the upper opening 201 of the receiving portion 200 is surrounded and closed by the receiving bag 103, the odor problem can be greatly alleviated.

In another embodiment, not shown, the outer side of the receiving portion 100 is joined together by a heat-sealing process at only one of the left or right edges and the lower edge, while the other of the left or right edges and the upper edge remain separated, forming a pocket-like structure open at both sides, which makes the upper opening of the receiving portion 200 more accessible.

Fig. 6 shows the urine bag before the folding operation, and the dotted line in the figure shows the position of the fold B. As shown by the arrow in fig. 6, the portion of the urine bag located on the upper side of this folded portion B is folded back by approximately 180 degrees toward the lower storage bag 103. The position of the turnover part B is higher than the liquid level of the urine in the urine bag, so that the urine bag can not be subjected to large resistance during turnover. Fig. 6 shows that the position of the folded portion B is substantially the position where the lower opening 202 of the access portion 200 is located. Preferably, the position of the folded portion B is higher than or equal to the position of the lower opening 202 and lower than or equal to the position of the lower edge of the hardened portion 300. The inventor researches and discovers that if the position of the turnover part B is higher than or equal to that of the lower opening 202, the turnover operation can further press the backflow-preventing part, and the backflow-preventing effect is enhanced; if the position of the folded part B is higher than the position of the lower edge of the hardened part, the hardened part 300 is folded during the folding process, which increases the resistance of the folding operation and risks damaging the urine bag.

Figure 7 shows a front view of the urine bag after the folding operation; fig. 11 shows a side view of the urine bag at this time. As shown, the upper opening 201 of the access portion 200 of the urine bag and the portion near the upper opening 201 have entered the receiving bag 103. In order to prevent the receiving portion 200 of the urine bag from accidentally falling out of the receiving bag 103, a protruding adhesive portion 104 may be provided at the upper side edge of the receiving portion 103, and as shown in fig. 7, the inside of the adhesive portion 104 is provided with an adhesive which can be adhered to the corresponding outside of the receiving portion 200 of the urine bag, thereby fixing the receiving portion 200. The bonding portion 104 shown here is merely an example. Preferably, in an embodiment not shown, a strip-shaped adhesive portion may be provided along the inside of the upper side edge of the receiving sheet 102 over the entire width, and when the receiving portion 200 enters the receiving bag 103, this strip-shaped adhesive portion will adhere the outside of the accommodating portion 100 and the outside of the receiving portion 200 to form a sealing portion that hermetically isolates the inside and the outside of the receiving bag 103, which may prevent odor from the upper opening 201 of the receiving portion 200 from leaking out to the environment to a greater extent.

Many modifications and variations of the design are possible in addition to the exemplary construction of the urine bag described above.

Fig. 12 shows a urine bag according to a first modification, in which a normally closed valve 105 is provided on the lower side of the containing portion 100 of the urine bag, and when the valve 105 is opened, urine in the containing portion 100 can be discharged. This arrangement allows the user to dispose of the urine bag after emptying the urine, or to reuse the urine bag.

In addition, in this first modification, as shown in fig. 12, the upper edge of the hardened portion 300 is lower than the upper opening 201 of the access portion 200, and the upper opening 201 of the access portion 200 has a circular seam 203 formed by eversion. This rounded mouth 203 can comfortably fit the user's body and avoid cutting the user's skin.

Fig. 17 shows a schematic construction of a urine bag according to another embodiment of the invention. This embodiment differs from the embodiment shown in fig. 5 in that the access portion 200 is not of unitary construction, but rather comprises two separate upper and lower access portions 205, 206. The upper access portion 205 defines an inverted conical interior chamber for receiving and securing the inverted conical hardened portion 300. Further, the hardened portion 300 is connected to the take-up portion 205 by a heat-sealing line H. The lower edge of the upper taking part 205 is fixedly connected to the upper edge of the accommodating part 100, and preferably, the upper taking part 205 and the accommodating part 100 may be formed as an integral structure. The lower receiving portion 206 has a hollow thin-walled cylindrical structure, and a portion of the lower edge of the hardened portion 300 is inserted into the upper opening of the lower receiving portion 206 and fixed to the lower receiving portion 206. Thus, the lower edge of the hardened portion 300 and the lower opening 202 of the lower catch portion 206 are spaced apart by a distance, so that a backflow prevention portion is formed near the lower opening 202 of the lower catch portion 206, and when two opposite inner surfaces thereof (i.e., two opposite inner surfaces of the lower catch portion 206) are fitted to each other, urine inside is prevented from overflowing to the outside.

Although not shown, the modified and improved concepts described above in connection with fig. 12-16 may be applied to the alternative embodiment shown in fig. 17. For example, when the modification concept in fig. 16 is applied, the upper pickup portion 205 may be entirely provided inside the accommodating portion 100. That is, the top take-up portion 205 may be formed of two opposing rectangular sheets, and left and right edges of the rectangular top take-up portion 205 are connected to left and right edges of the receiving portion 100. Two oblique heat-bonding lines H1 and H2 are formed by heat-pressing at a position near the middle of the upper receiving portion 205, so that an inverted conical cavity is formed at the middle position of the upper receiving portion 205, the upper side of the inverted conical cavity forms the upper opening 201 of the receiving portion 200, the inverted conical hardened portion 300 is disposed inside the upper receiving portion 200 so as to adhere to the inner wall of the inverted conical cavity of the upper receiving portion 205, and the hardened portion 300 is connected to the upper receiving portion 205 by the heat-bonding line H.

Fig. 18 shows a plurality of urine bags 10 in a package. Each urine bag 10 is in the form of a sheet having a small dimension in the thickness direction, and this structure can save a storage space to a great extent. In addition, as shown in fig. 18, a paper towel P may be provided between two adjacent sheet-shaped urine bags 10, as shown by a dotted line, for a user to wipe his or her body after using the urine bags 10. In another embodiment, as shown in fig. 19, a tissue may be placed in advance in the receiving bag 103 of the urine bag 10 for receiving the receiving portion 200 later.

In some embodiments, the urine bag 10 of the present invention is made using biodegradable materials. The urine bag containing urine can be directly thrown away in the field, and after a period of time (for example, 3 months), the material of the urine bag 10 is completely degraded and eliminated, and the urine in the urine bag can be used as fertilizer to enter the soil. Accordingly, the urine bag 10 of the present invention can be used as a treatment apparatus for treating domestic sewage, such as urine, in an environmentally friendly manner.

Fig. 20 shows another embodiment. Only the differences from the embodiment shown in fig. 4 will be described below. In this embodiment, the receiving portion 200 is formed in an hourglass shape, i.e., includes an upper half 401 having an inverted cone shape and a lower half 402 having a cone shape, the upper half 401 being located outside the receiving portion 100 for receiving therein the hardened portion 300, e.g., a hollow paper cup having a truncated cone shape, and the lower half 402 being located inside the receiving portion 100 for forming a backflow preventing portion. In addition, in the lower half 402, a plurality of discrete bonding points 403 are provided for bonding the inner surfaces of two opposing sheets of the lower half 402 at a plurality of discrete locations. The glue dots 403 prevent the two sheets of the bottom half 402 from spreading apart under the impact of liquid, improving the anti-backflow effect. In the embodiment shown in fig. 20, the receiving portion 100 may not be square, and the lower half 402 of the receiving portion 200 corresponding to the upper side thereof may have a trapezoidal profile, which is cut to save material by making a corner unnecessary compared to the square profile. As shown in fig. 20, a urine absorbent material 106 is provided in the containing section 100.

Fig. 21 shows the urine bag of fig. 20 after the stiffening portion 300 has been removed. As for the structure as a whole, the vicinity of the upper half 401 is a double-layer structure in which the front and rear sheets form a passage leading from the upper side opening to the lower half 402; the lower half 402 is of a four-layer structure, the two innermost layers are two sheets of the take-up portion 200, which form a passage therein leading from the outlet of the upper half 401 to the inside of the receiving portion 100; the outermost two sides of the four-layer structure are portions of two sheets of the receiving portion 100, which are spaced apart from the outer walls of the lower half 402 (i.e., the backflow preventing portion) of the adjacent receiving portion 200, respectively, for receiving liquid.
