2. Description of the Related Art A variety of emergency toilets and toilet articles have been developed in the past, but due to the large size of the installation and the extremely high cost, not only at home but also at home. The fact is that the preservation of emergency supplies in companies and local governments has not progressed much. Sewage treatment bags were developed exactly to overcome this situation, and several companies, including the applicant, now supply this type of product, but they are simply plastic bags or water-absorbing polymers inside. There are a lot of things that just put coagulated paper, etc., so that in case of emergency, you can use it immediately by simply spreading it, it is easy to store, and the municipal waste disposal department can accept the disposal as garbage Are almost nonexistent.

[0003] A waste disposal bag manufactured by Japanese Patent Application No. 10-24086 has been developed by the applicant and approved by the local government's waste disposal department for disposal as garbage. Although highly acclaimed,
Since the manufacturing process is complicated, it has been difficult to reduce the manufacturing cost, and it has been difficult to further lower the product price and achieve further spread.

[0004]

Therefore, in the present invention,
Further reduce the cost of producing effective waste disposal bags so that households, businesses, and local governments can store enough of the waste disposal bags that can be used immediately in case of emergency, especially for the sick and disabled. In order to eliminate the difficulty of setting the water-absorbent sheet in the storage bag for the vulnerable person, manufacture a filth disposal bag that can be used just by spreading it, and
With the task of further simplifying the manufacturing process,
It was developed.

Subsequently, point thermocompression bonding is performed from both the front and back surfaces of the storage bag 2 where the free edge 12 of the folded water absorbent sheet 1 is located. In the drawing, a thermocompression-bonded portion 3 (portion indicated by oblique lines) to which thermocompression bonding is applied is a storage bag 2.
However, in reality, the thermocompression-bonded portion 3 to be thermocompression-bonded also exists on the back surface of the storage bag 2 at the same position. The thermocompression bonding is performed at an appropriate temperature at which the folded water-absorbent sheets 1 are not joined to each other.

The thermocompression bonding may be performed separately on the front and back heat-bonded portions 3 on the front and back surfaces of the storage bag 2. Is desirable. Further, in the drawings, the thermocompression bonding portion 3 is shown in parallel with the free edge 12 of the water absorbent sheet 1, but the position and mode of thermocompression bonding are not necessarily limited to this. Here, the point thermocompression bonding means that it is not necessary to thermocompression-bond all of the free edge 12, and that part of the free edge 12 may be thermocompression-bonded.

When the storage bag 2 is completely pressed into the thermocompression-bonding portion 3 from both the front and back sides, the two folded water-absorbent sheets 1 are not joined to each other, and one of the free edges 12 of the storage bag 2 is stored in the storage bag. The heat-pressed portion 3 on the front surface 2 and the other of the free edges 12 are respectively joined to the heat-pressed portion 3 on the back side of the storage bag 2 to complete a desired waste disposal bag. become.

Next, in the embodiment shown in FIG. 2, a continuous tubular bag material 4 is used in place of the storage bag 2. Bag material 4
Any material can be used as in the case of the storage bag 2 described above, but it is desirable to use a calcium carbonate-containing polyethylene material so that it can be incinerated similarly to a paper diaper.

In the present embodiment, the folded water-absorbent sheet 1 is inserted into the continuous tubular bag material 4 so that the bent portion 6 faces downward. Thermocompression bonding is performed on both sides of the bag material 4 where the free edge 12 of the water absorbent sheet 1 is located, and further thermocompression bonding is performed on the lower surface of the bag material 4 which does not intersect with the bent portion 6 of the water absorbent sheet 1 and is closed. A portion 5 (a portion indicated by oblique lines) is formed.

The thermocompression-bonded portion 3 to be subjected to thermocompression bonding (the hatched portion) exists not only at the front surface of the bag material 4 but also at the same position on the back surface as in the above-described embodiment. Preferably, both sides are thermocompression-bonded at the same time in order to increase the pressure. Note that the closing portion 5 only needs to apply thermocompression bonding from only one of the front and back surfaces of the bag material 4. As in the previous embodiment, the thermocompression-bonded portion 3 is, as shown in FIG.
Although it is shown as a rectangle parallel to 2, the position and mode are not limited to this, and only a part of the free edge 12 may be joined by point thermocompression bonding.

When the closing portion 5 is thus formed, the continuous cylindrical bag material 4 and the bag material 4 'which will be the material of the waste disposal bag are cut as shown in FIG. The waste disposal bag is completed. In the completed waste disposal bag, similarly to the above-described embodiment, the folded water-absorbent sheets 1 are not joined to each other, and one of the free edges 12 is the heat-bonded portion 3 on the front side of the bag material 4. The other free edge 12 is joined to the thermocompression-bonded portion 3 on the back surface side of the bag material 4.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a method for manufacturing a waste disposal bag according to the present invention will be described. First, in the case of claim 1 using an existing storage bag, the water-absorbent sheet 1 is folded in two at the folding line 11 as shown in FIG. 4 and inserted into the lower inside of the storage bag 2. When the storage bag 2 is inserted as specified, the storage bag 2 is subjected to thermocompression bonding simultaneously or individually from the thermocompression-bonded portions 3 on both front and back surfaces. This process can be done manually by humans,
Further, it can be performed mechanically.

Next, in the case of claim 2, wherein the continuous tubular bag material 4 is used, the water-absorbent sheet 1 is inserted into the continuous tubular bag material 4 in the same manner as described above. Thermocompression bonding from the thermocompression-bonded portions 3 on both front and back sides of the bag material 4, and then thermocompression bonding from the lower surface of the bag material 4 which does not intersect with the bent portion 6 of the water-absorbent sheet 1 to form the closed portion 5. Performed by In this embodiment, the closing portion 5 may be formed first, and then the thermocompression bonding to the thermocompression bonding portion 3 may be performed. Further, in the present embodiment, since the continuous tubular bag material 4 is used, it is assumed that the operation is performed mechanically by a flow operation. However, the operation can be performed manually by a human.

The coagulated paper used for the water absorbent sheet 1 is as follows.
It is planned to use a water-absorbing polymer, a mixture of a water-absorbing polymer and flocculent pulp, or a case where the coagulated paper is further covered with a water-soluble paper sheet. It is prepared as a water-absorbing sheet 1 having contents.

The oblique direction applied to both ends of the closing portion 8 of the storage bag 2 and the closing portion 5 of the bag material 4, that is, the process of thermocompression bonding to the thermocompression bonding portion 7 is usually performed by the thermocompression bonding portion 3. Although it is planned after thermocompression bonding to the substrate, the order of the steps may be changed.

A procedure for treating waste using the waste disposal bag thus manufactured will be described. When used inside the facility, the opening of the waste disposal bag is rolled into the toilet seat of the existing toilet bowl, and the remaining part is dropped inside the toilet bowl for use outside the facility or even inside the facility. In the case of bedridden elderly people who cannot move their hands, use the opening of the bag against the buttocks.

The filth falls onto the water-absorbent sheet 1 attached inside the bag, and is absorbed and coagulated by the action of a water-absorbing polymer or the like. When the use is completed, remove the opening of the waste disposal bag from the toilet seat, close it, and tie it with a string or the like. After some time has passed and the waste has been solidified, open the waste disposal bag again, turn the bag upside down and discard only the solidified waste from inside into a toilet or a treatment plant, tie the mouth again and collect with the garbage do that for me. At that time, since the water-absorbent sheet 1 is firmly fixed inside the bag, the water-absorbent sheet 1 does not drop together with dirt.
Therefore, it becomes possible to treat it as garbage in the same manner as a disposable diaper.

[0031]

The method for producing a waste disposal bag according to the present invention comprises:
Since the water-absorbent sheet can be attached to the storage bag or bag material by a single thermocompression bonding, the process has been greatly simplified compared to the conventional manufacturing method, which had to be attached and attached several times. .

As a result, the manufacturing cost of the waste disposal bag can be greatly reduced, and a more inexpensive waste disposal bag can be provided. Therefore, it is possible to purchase and store a necessary amount of material with confidence, not only at home but also at a facility used in large quantities such as a company, a local government, a hospital or a nursing center.

In the waste disposal bag manufactured according to the present invention, a water-absorbent sheet is set inside the bag and can be used immediately without any troublesome work in any situation. By leaving it in the sack, it can be widely used in sports and leisure scenes.

In addition, in the waste disposal bag manufactured according to the present invention, the coagulated paper in which the coagulated paper is previously coated with the non-woven fabric is attached inside the bag, so that the waste bag and the coagulated paper are stored separately. The coagulated paper does not eat moisture and can be stored for a long time.

Further, the waste disposal bag manufactured by the present invention is
By using polyethylene containing calcium carbonate in the material of the storage bag or bag material, if only the coagulated waste is discarded in a toilet or a treatment plant, it can be incinerated in the same manner as a paper diaper. Therefore, it is possible to collect the waste by the municipal waste management department, and it is possible to sufficiently cope with environmental problems that have recently become a problem.
