Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a napkin that absorbs blood and water such as women's menstruation and bleeding, hemorrhoids regardless of gender, incontinence, and discards each time. The present invention relates to a water-soluble napkin that can be discarded together with water in a flush toilet.

[0002]

2. Description of the Related Art Conventionally, many kinds of napkins of this kind have been developed and marketed by many manufacturers, but most post-use treatments of napkins are wrapped in paper in a waste container arranged in the toilet. It is the situation that is being thrown away.

[0003]

[Problems to be solved] However, if a certain amount of time has passed between the waste container and the waste container being wrapped in paper and disposed of in a waste container placed in the toilet, a strange odor is generated, which causes discomfort. However, it is unsanitary and has a problem.

In a public toilet or the like, a person with bad manners flushes the toilet bowl with water, which causes troubles such as clogging of piping.

[Means for solving the problem]

The present invention was devised as a result of study in view of the above-mentioned problems, and has an inner Japanese paper layer formed of water-decomposable Japanese paper and a finely divided absorbent cotton polymerized on the inner Japanese paper layer on the surface. A water-absorbing layer in which a large number of chips that have been heated and compressed to the extent of browning are lined up in a sheet, and a waterproof layer in which a large number of ultra-thin sheets whose main component is starch that is a carbohydrate that polymerizes in the water-absorbing layer are laminated. And an outer Japanese paper layer formed of water-decomposable Japanese paper that polymerizes on the waterproof layer, and further, a water-absorbing layer is formed by arranging a large number of chips in a sheet form and in two stages.

Therefore, an object of the present invention is to provide a water-soluble napkin which can be discarded by flushing the napkin after use with the water in the flush toilet bowl.

[0007]

The water-soluble napkin of the present invention has a structure in which the inner Washi paper layer, the water absorbing layer, the waterproof layer, and the outer Washi paper layer constituting the napkin are all water-soluble and water-degradable, so that they can be flushed with water in the flush toilet after use. It can be discarded.

EXAMPLES The water-soluble napkins of the present invention will be specifically described below with reference to the drawings of the examples.

FIG. 1 is a schematic explanatory view of an embodiment of the water-soluble napkin of the present invention, FIG. 2 is a schematic explanatory view of the next embodiment of the water-soluble napkin of the present invention, and FIG. 3 is a water-soluble of the present invention. It is a schematic explanatory drawing of the superposition | polymerization state of the following example of napkin.

The present invention relates to a napkin 1 which absorbs blood and water such as hemorrhoids and hemorrhage of women, hemorrhoids regardless of gender, incontinence, and discards each time. Specifically, the napkin 1 after use is used. The present invention relates to a water-soluble napkin 1 which can be disposed of together with water in a flush toilet, wherein the water-soluble napkin 1 according to claim 1 comprises an inner Japanese paper layer 2 formed of water-decomposable Japanese paper and an inner Japanese paper layer 2. A water-absorbing layer 3 in which a large number of chips 3a, which are heated and compressed to the extent that the finely divided absorbent cotton that is polymerized is browned on the surface, are arranged in a sheet form, and starch, which is a carbohydrate that polymerizes in the water-absorbing layer 3, is a main component. And a waterproof layer 4 formed by laminating a large number of ultra-thin sheets 4a, and an outer Japanese paper layer 5 formed of water-decomposable Japanese paper that polymerizes on the waterproof layer
It is equipped with and.

Further, the water-soluble napkin 1 according to claim 2
In the water-soluble napkin 1 according to claim 1, the water-absorbing layer 3 is formed by arranging a large number of chips 3a in a sheet shape and in two stages.

That is, the inner Japanese paper layer 2 of the water-soluble napkin 1 of the present invention which comes into contact with the human body is made of human-friendly Japanese paper, and when the Japanese paper is poured into a large amount of water, the entanglement of fibers is easily decomposed, Although the fibers become separated and float in water, it is preferable that the entanglement of the fibers is quickly decomposed by water if the fibers are appropriately cut when the Japanese paper is strained in advance.

The water-absorbent layer 3 that is polymerized on the outside of the inner Washi layer 2 is absorbent cotton similar to that on the market. The absorbent cotton is peeled to an appropriate thickness and cut into a rectangular shape by a cutter or the like. , For example, it is subdivided into cubes of about 5 mm to 6 mm, and further the subdivided cubic absorbent cotton is roasted on an iron plate or the like heated on the surface to heat it to the extent that it is browned and the surface is browned. A plurality of chips 3a, which are compressed under pressure by pressing absorbent cotton that has been heated to a certain degree, are arranged in a sheet form.

That is, as is well known, absorbent cotton has a large amount of water absorption and a strong water absorbing ability, so absorbent cotton has been used in the water absorbent layer in conventional products, but since it is not subdivided, a large amount of absorbent cotton is used when flushed in a flush toilet bowl. Although water absorbs water, it is a lump, and when it flows into the toilet bowl, it adversely affects the piping. However, since the water-absorbing layer 3 of the water-soluble napkin 1 of the present invention is subdivided, it is subdivided. The absorbent cotton is disassembled and easily decomposed with water.

The absorbent layer 3 has a large number of chips 3a formed by heating the finely divided absorbent cotton to the extent that the surface of the absorbent cotton is browned, and the numerous chips 3a are arranged side by side. The water absorption capacity is further increased, the deodorizing effect is provided, and the air permeability is maintained, so that it is irreversible.

Further, the waterproof layer 4 is prepared by dissolving starch, the main component of which is carbohydrate, in water, and drying the water after the dissolution, for example, to 0.
The waterproof layer 4 is formed by forming an ultrathin sheet 4a having a thickness of about 05 mm to 0.1 mm and laminating about 6 to 10 sheets of the ultrathin sheet 4a.

That is, the waterproof layer 4 which is polymerized on the outside of the water absorbing layer 3 is formed on the ultra-thin sheet 4a containing starch which is a carbohydrate as a main component, and the starch easily dissolves in a large amount of water. However, a small amount of blood that has passed through the water absorbing layer 3 is combined with the starch of the waterproof layer 4 and coagulates, and the purpose of hemostasis can be sufficiently fulfilled.

Further, the outer Japanese paper layer 5 superposed on the outer side of the waterproof layer 4 is made of the same Japanese paper as the inner Japanese paper layer 2 described above. The layer 5 is formed by slightly expanding the width so as to enclose the water absorbing layer 3 and the waterproof layer 4, and as shown in FIG. 3, attaches the width slightly in the shape of a bag by means of gluing. In addition, a double-sided tape may be attached to the outside of the outer Japanese paper layer 5 for attaching to underwear or the like at the time of mounting.

In addition, the water-soluble napkin 1 according to claim 2 is the same as the water-soluble napkin 1 according to claim 1, in which a large number of chips 3a to be the water absorbing layer 3 are formed as shown in FIGS. It is arranged in a shape and in two stages.

That is, the water-absorbing layer 3 in which a large number of chips 3a are arranged in two stages has doubled effects such as water absorption and deodorization.

[0021]

EFFECTS OF THE INVENTION The present invention can be used for women's menstruation and sores, hemorrhoids regardless of gender, incontinence, etc. by the above-mentioned constitution, and after use, it can be discarded by flushing it with water in a flush toilet. It is an epoch-making and highly practical invention.
