DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sewage treatment bag capable of washing and draining waste while containing filth of a cared person or stool such as pet droppings such as dogs and cats, and a method of manufacturing the same.

[0002]

2. Description of the Related Art Generally, wastes of a cared person are disposed in a plastic bag or the like and disposed of as garbage. In this case, grasp the waste using tissue paper or toilet paper so that the waste does not directly touch the hand,
It is common practice to put this in a plastic bag or the like, but if the filth contains a lot of moisture, keep your hands clean even if you use tissue paper or toilet paper. It was difficult to put such waste in a bag.

[0003] In addition, it is common practice to treat feces of pets such as domestic dogs by carrying a scoop and a plastic bag when the dog walks, picking up the feces with the scoop, and collecting the feces in the plastic bag. Even in this case, it is troublesome to carry a scoop and the collection operation is not easy, and a manner violation of leaving feces on a violent street or the like is rampant.

[0004] In any of the above cases, the filth and feces put in the plastic bag must be kept at home until the date of collecting the garbage, causing odor and unsanitary environment. Often.

To solve such a problem, for example, Japanese Utility Model Publication No. Hei 8-4866 discloses a method in which a water-dispersible paper and a water-soluble film are laminated, and the water-dispersible paper is placed on the outside. There has been proposed a pet excrement disposal bag in which a water-soluble film is disposed inside to form a bag. This processing bag grasps the dirt etc. with the hand inserted in this bag, and in that state, turns the bag so that the water-dispersible paper is on the inside and the water-soluble film is on the outside, and the dirt etc. is put in the bag. It is to be collected and collected. According to such a processing bag, it is possible to reliably collect dirt and the like in the bag without soiling the hands, and because the constituent material of the bag is water-dispersible or water-soluble, the dirt can be stored. The washed bags can be directly washed and drained.

[0006]

However, the processing bag disclosed in the above publication still has the following problems to be improved. That is, since the treatment bag has a water-dispersible paper and a water-soluble film in a laminated state, when the filth contains a large amount of moisture, the moisture of the contained filth is reduced. It permeates the inner paper in a relatively short time and seeps into the outer film. Then, since the outer film is water-soluble, the film dissolves at the bottom of the bag, and in the worst case, the collected dirt or the like falls down. Also,
Even if such a worst case situation does not occur, the moisture of the filth seeps into the outer film, and this will emit a bad smell to the surroundings.

The present invention has been conceived under such circumstances, and solves the above-mentioned problems of the prior art. Even if the collected filth contains a relatively large amount of water, It is an object of the present invention to provide a sewage treatment bag capable of storing and holding such sewage without any problem for a relatively long time, and furthermore, capable of performing washing and drainage treatment and a method of manufacturing the sewage treatment bag at low cost and efficiently. I have.

[0008]

DISCLOSURE OF THE INVENTION In order to solve the above problems, the present invention employs the following technical means.

That is, the waste disposal bag provided by the first aspect of the present invention is a waste disposal bag formed by disposing a water-dispersible paper on the outside and a water-soluble film on the inside. The water-dispersible paper and the water-soluble film are
Both are continuous in a folded shape at the bottom of the bag, both are substantially separated at the bottom of the bag, and both are integrated at a portion other than the bottom of the bag. .

More specifically, the above-mentioned waste disposal bag is composed of a water-soluble film in which the front panel and the rear panel are continuously formed in a folded shape at the bottom at the bottom, and the front panel and the rear panel. Are folded back at the bottom,
A water-dispersible paper disposed outside the bag-shaped water-soluble film, wherein the water-soluble film and the water-dispersible paper are separated from each other at the bottom folded portions thereof. At the same time, they are joined at portions other than the bottom.

[0011] In a preferred embodiment, the water-soluble film forms an inner bag, and the water-dispersible paper forms an outer bag. And are joined at the sides.

In the waste disposal bag according to the present invention, water-dispersible paper is disposed outside the inner bag made of a water-soluble film. This water-dispersible paper is preferably in the form of an outer bag, but does not necessarily have to be in the form of a bag.
It may be merely attached to the outside of the inner bag.
However, the inner bag has a folded back at the bottom and the front side panel and the back side panel are continuous, and the water-dispersible paper also has a folded back at the bottom and the front side panel and the back side It is necessary that the side panel is continuous and that both are separated from each other at the folded portion at the bottom and that they are joined at a portion other than the bottom.

In this waste disposal bag, the waste is grasped by the hand inserted into the bag, and in this state, the bag is turned over to accommodate the waste. At this time, the dispersible paper enclosing the filth is further housed in a bag made of a water-soluble film.

[0014] When grasping the dirt, it is grasped through the opaque paper, so that there is little resistance, and since the paper directly wraps the dirt, the dirt can be gripped without slipping. In addition, since the bag-shaped water-soluble film and paper are integrated at a predetermined portion, when the bag is turned over, the paper also turns over well, and the paper is properly placed in the water-soluble film bag. It is in a state of wrapping up waste. And the bag-shaped water-soluble film and paper are continuous with the front and back panels folded at the bottom at the bottom, and these are separated from each other at the bottom folded portion, so that the paper wrapping the filth and the film on the outside thereof A moderate air layer is formed between the bottom and the bottom. Therefore, even if the filth contains a lot of water, the paper properly supports the weight of the filth and the water is first absorbed by the paper, so that the water oozes out to the outer film in a short time. There is no. As a result, for example, when a dog walks, even if the dog's feces with high water content are collected, it can be taken back without oozing out of the water on the way and causing an unpleasant odor, or dissolving the bag and dropping the waste. Will come out. And, since the waste collection bag according to the present invention is made of water-dispersible paper and a water-soluble film, together with the collected waste,
Wastewater can be treated in a flush toilet.

In a preferred embodiment, the upper opening of the inner bag made of a water-soluble film extends above the upper opening of the outer bag made of water-dispersible paper. In this case, the bag can be easily closed by tying the mouth of the bag in which the waste is collected. At this time, if the mouth of the bag is closed so that a certain amount of air is contained, an air layer between the paper surrounding the waste and the outer film can be more reliably formed, and the waste containing a large amount of moisture can be removed. It can be held for a long time.

The method for manufacturing a waste disposal bag provided by the second aspect of the present invention is characterized in that a water-soluble film having a predetermined width is superimposed on a band-shaped water-dispersible paper having a predetermined width, and the water-dispersible paper is used. A first step of transporting the two pieces while folding them at the middle part in the width direction so as to be on the outside, a second step of heat-sealing the transported article of the first step at predetermined intervals in the feed direction, and a second step of transporting the transported article. And a third step of cutting at the heat-sealed portion formed in step (a).

According to such a method, the waste disposal bag according to the present invention can be manufactured at low cost and high efficiency.

[0018] Other features and advantages of the present invention will become more apparent from the detailed description given below with reference to the drawings.

[0019]

Preferred embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is an overall view of one embodiment of a waste disposal bag 10 according to the present invention, FIG. 2 is a sectional view taken along the line II-II in FIG. 1, and FIG. 3 is a view taken along the line III-III in FIG. It is sectional drawing. This sewage treatment bag 10 is composed of an inner bag 2 made of a water-soluble film 2.
0 and an outer bag 30 made of water-dispersible paper 3.

The inner bag 20 has an opening 24 in the upper part by the front side panel 21 and the back side panel 22 being connected by a bottom folded part 23 and both panels 21 and 22 being fused at both sides. It has a bag shape.

In the outer bag 30, the front panel 31 and the rear panel 32 are connected to each other by a bottom folded portion 33, and both panels 31, 32 are fused at both sides to form an opening 34 at the top. It has a bag shape. The inner bag 20 and the outer bag 30 are integrated by overlapping and fusing the panels 21, 22, 31, and 32 on both sides. However, the inner bag 20 and the outer bag 30 are substantially separated from each other at the bottom folded portions 23 and 33.

In the present embodiment, the length of the inner bag 20 is longer than the length of the outer bag 30, so that the upper opening 24 of the inner bag 20 is further higher than the upper opening 34 of the outer bag 30. Have been extended.

The water-dispersible paper 3 needs to have an appropriate water-dispersibility, and its scale is determined by JI
The “easiness of loosening” of SP4501 is preferably 100
Use one within seconds. A typical example of such paper is
There is paper used as toilet paper.

The water-soluble film 2 is made of, for example, a water-soluble polymer having a polyvinyl alcohol, a carboxyl group, a sulfonic acid group, a phosphoric acid group, or a salt thereof, a pullulan film, gelatin, hydroxypropylcellulose, hydroxypropylmethylcellulose, hydroxyethylcellulose. A film based on a water-soluble substance such as a cellulose derivative such as methyl cellulose is preferably used.

Next, a method of using the waste disposal bag 10 will be described. As shown in FIG. 4, this waste disposal bag 10 grasps the waste M with the hand inserted in the bag, and as shown in FIG. At this time, the dispersible paper 3 wrapping the waste M is further stored in a bag made of the water-soluble film 2.

When the dirt is to be gripped, the dirt is gripped via the opaque paper 3 so that there is little resistance, and since the paper directly wraps the dirt, the dirt M can be gripped without slipping. Further, since the outer bag 30 made of a water-soluble film and the inner bag 20 made of water-dispersible paper are integrated with each other on both sides, when the entire bag 10 is turned over, a paper-made bag together with the outer bag 30 is used. Inner bag 20 also flips well,
Among the bags of the water-soluble film 2, the bag made of the water-dispersible paper 3 properly wraps the waste M. And
The outer bag 30 and the inner bag 20 have the front and back panels continuous at the bottom in a folded state, and are separated from each other at the bottom folded portions 23 and 33, so that the paper 3 wrapping the filth M and the outside are separated. An appropriate air layer is formed between the film and the water-soluble film 2. Therefore, even if the waste M contains a large amount of moisture, the paper properly supports the weight of the waste and the moisture is first absorbed by the paper, so that the moisture seeps into the outer film in a short time. Never.

Further, in the above embodiment,
Upper opening 24 of inner bag 20 made of water-soluble film 2
Is an upper opening 34 of an outer bag 30 made of water-dispersible paper 3.
It extends upward. In this way, the waste M
The bag can be easily closed by tying the mouth of the collected bag. At this time, if the opening of the bag is closed so that a certain amount of air is contained, the air layer between the paper 3 wrapping the waste M and the outer film 2 can be formed more reliably, and the moisture can be increased. Long-term retention of the contained waste becomes possible.

As a result, according to the above-mentioned waste disposal bag 10, even if, for example, dog feces with a high water content are collected during the walk of the dog, the water oozes out on the way to emit an unpleasant odor or the bag is dissolved. The filth can be brought back without falling down. Since the waste collection bag is made of water-dispersible paper and a water-soluble film, the waste can be drained in a flush toilet together with the collected waste as shown in FIG.

Next, the waste collection bag 10 having the above structure can be manufactured, for example, as follows.

That is, as shown in FIG. 8A, a water-soluble film 2 having a predetermined width is formed on a band-shaped water-dispersible paper 3 having a predetermined width.
Are stacked, and while the paper 3 is conveyed while being folded at the widthwise intermediate portion so that the water-dispersible paper 3 is on the outside, the conveyed materials are heat-fused at predetermined intervals in the feeding direction. The cutting is performed at the formed heat-sealed portion 40.

If a film having a predetermined heat melting property is used as the water-soluble film 2, it is possible to form the water-dispersible paper 3 by the heat fusion as described above, without requiring a step of applying an adhesive. The water-soluble film 2 and the water-soluble film 2 can be thermally fused to each other in a polymerization state with the paper 3 facing outward.

According to the above-described manufacturing method, the waste disposal bag 10 having the above-described structure can be manufactured at low cost and high efficiency by using the conventional bag making machine.
Can be manufactured.

Of course, the scope of the present invention is not limited to the above-described embodiment, and various changes in the matters described in the claims are all included in the scope of the present invention. The point of the present invention is that the water-dispersible paper 3 is located outside the bag made of the water-soluble film 2 and the front side panel 31 and the back side panel 32 are folded (33) at the bottom of the bag. What is necessary is just to be continuous and to be integrated with the bag of a water-soluble film in an appropriate part. Therefore, in the embodiment shown in FIG. 1, the water-dispersible paper 3 arranged on the outside is integrated with the water-soluble film 2 over the entire length in the vertical direction on both sides except for the bottom, so that the paper 3 has a bag shape. However, the paper 3 does not need to be in the form of a bag, for example, in FIG. 1, only the upper part on both sides of the paper 3 may be integrated with the water-soluble film 2. Alternatively, in FIG. 1, only one side of the paper 3 may be integrated with the water-soluble film 2. However, also in these cases, it is needless to say that the water-soluble film 2 needs to be in a bag shape.

Alternatively, as shown in FIG. 9, the front side panel 31 and the back side panel 32 are connected to the outside of the bag 20 made of the water-soluble film 2 at the bottom folded portion 33 so that the water dispersibility is reduced. The case where the paper 3 is attached is also included in the scope of the present invention. In this case, the water-dispersible paper 3 is applied to the bag 20 of the film 2 by, for example, an adhesive.
Will be partially joined to and integrated with the surface of the.

Further, the outer water-dispersible paper has a double structure (including a partially double structure), whereby the holding power of water-rich filth can be enhanced.

Can be manufactured.

Of course, the scope of the present invention is not limited to the above-described embodiment, and various modifications in the matters described in the claims are all included in the scope of the present invention. The point of the present invention is that the water-dispersible paper 3 is located outside the bag made of the water-soluble film 2 and the front side panel 31 and the back side panel 32 are folded (33) at the bottom of the bag. What is necessary is just to be continuous and to be integrated with the bag of a water-soluble film in an appropriate part. Therefore, in the embodiment shown in FIG. 1, the water-dispersible paper 3 arranged on the outside is integrated with the water-soluble film 2 over the entire length in the vertical direction on both sides except for the bottom, so that the paper 3 has a bag shape. However, the paper 3 does not need to be in the form of a bag, for example, in FIG. 1, only the upper part on both sides of the paper 3 may be integrated with the water-soluble film 2. Alternatively, in FIG. 1, only one side of the paper 3 may be integrated with the water-soluble film 2. However, also in these cases, it is needless to say that the water-soluble film 2 needs to be in a bag shape.

Alternatively, as shown in FIG. 9, the front side panel 31 and the back side panel 32 are connected to the outside of the bag 20 made of the water-soluble film 2 at the bottom folded portion 33 so that the water dispersibility is reduced. The case where the paper 3 is attached is also included in the scope of the present invention. In this case, the water-dispersible paper 3 is applied to the bag 20 of the film 2 by, for example, an adhesive.
Will be partially joined to and integrated with the surface of the.

Further, the outer water-dispersible paper has a double structure (including a partially double structure), so that the holding power of waste containing much water can be increased.
