Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-absorbing animal urine disposal material which is granulated or pelletized mainly with organic fibers such as cellulose fibers or organic powders.

[0002]

2. Description of the Related Art U.S. Pat. No. 1,696,885 provides a urine disposal material for pet animals, which is composed of pulp or a residue thereof as a main component, and an inorganic filler is added to the granulation material to granulate it. A patent application has been filed that uses wood flour or coffee bean extraction residue as the main component, or urinary treatment materials that have been colored appropriately to improve their commercial properties, but these treatment materials have recently been discolored by the pH of urination. There is provided an animal urinary disposal material in which the above-mentioned drug is blended so that the state before and after the use can be discriminated.

[0003]

However, if it is possible to distinguish the used portion (the portion that has been urinated) and the unused portion (the portion that has not been urinated) of the urine disposal material, only the used portion can be replaced. Although it is economical and can solve the problem of giving off a strange odor when left unattended, the conventional example is premised on the use of a drug that discolors due to the pH of urination. For example, it is suspected that it is suitable as a urine disposal material used at home alone,
It impairs the marketability. In addition, there is a concern about the problem of wastewater treatment after flushing into a toilet bowl.

[0004]

According to the present invention, in the above-mentioned animal urine disposal material having water absorbency, the material is covered with a surface layer capable of exposing the color of the nucleus when absorbing urine,
It provides a concept that makes it possible to determine the presence or absence of urination by using a composite layer structure. With this composite layer structure, it is possible to form a treatment material that enables the above determination without using the chemical.

As an example, the core portion is colored darker than the surface layer by a pigment or a dye to enable the above discrimination. As another example, the core portion is not positively colored, and the base material color originally possessed by the material is used so that the core portion becomes darker than the surface layer, and the discrimination is possible.

The above-mentioned pigments or dyes are water-soluble, and the pigments or dyes are exuded to the surface layer by absorption of urine so that the color of the nucleus portion can be exposed.

The treatment material is weighted by including an inorganic pigment containing calcium carbonate, clay or the like as a main component in the treatment material to prevent the scattering and the adhesion to the animal, and the exposed structure is obtained. . Inorganic pigments are suitable for the weight imparting effect, while coloring with organic pigments or organic dyes is appropriate in wastewater treatment.

[0008]

According to the present invention, since the excrement treating material has a multi-layered structure and the color of the nucleus can be exposed through the surface layer by the water content of urination, it is possible to use before and before urination without using a drug that develops color by urination. The subsequent state can be accurately determined, and the advantage of exchanging only the used part can be enjoyed.

[0009]

Examples As described above, the target animal urinary disposal material is, for example, pulp (including pulp residue), wood powder, or a ground product of coffee beans or an organic fiber or an organic powder represented by a residue after coffee distillation. Consists of a water absorbing material as the main component. Inorganic fillers, starch, water-absorbing polymers and the like are selectively blended with these water-absorbing materials. Also, crushed straw or crushed paper (paper dust, small piece of paper) is used as the treatment material.

As shown in FIGS. 1 and 2, the water-absorbent material is formed into a granular material 1 or a pellet-shaped material 2 having a size of a little finger and dried, and these aggregates are subjected to urination treatment. Alternatively, the water absorbing material is formed into a sheet, dried and then subjected to urination treatment.

As shown in FIGS. 1 and 2, the water-absorbing material forming the granular material 1 or the pellet-shaped material 2 is a core portion 1a, 2a.
Are covered with surface layers 1b and 2b which show the color of the core portions 1a and 2a when absorbing urine.

As an example, the core portions 1a and 2a have a surface layer 1b,
It is colored with a darker pigment or dye than 2b so that the coloring is exposed through the surface layers 1b and 2b when absorbing the urine. The core portions 1a and 2a have a single-layer structure and are colored as described above, or have a multi-layer structure and the outermost layer thereof is a coloring layer.

As another example, the core portions 1a and 2a may have a surface layer 1 depending on the color of the base material of the fibers or powders themselves.
Use a darker color than b and 2b.

In other words, the surface layers 1b and 2b are connected to the core portion 1
A light color (including a color called colorless such as white) is set to be lighter than a and 2a, and the core portions 1a and 2a are made darker than this. As means for utilizing the base material color of the material itself, the core parts 1a, 2
a is made of waste paper pulp (low-whiteness pulp), and the surface layer 1
b and 2b are made of virgin pulp or the like having a higher whiteness. Pulp here includes pulp sludge.

The waste paper pulp is colored by the ink component and has a dark gray color. The surface layers 1b and 2 made of fibers or powder such as virgin pulp having a higher whiteness
It is coated with b so that the color of the core portions 1a, 2a can be exposed through the surface layers 1b, 2b when absorbing urine.

Alternatively, the core portions 1a and 2a are formed by the residual powder after the coffee bean treatment, and the surface layers 1b and 2b are covered with a material having a water absorbing property such as pulp fiber or powder.

The residue after the coffee bean treatment that forms the core portions 1a and 2a has a brown color, and the surface layers 1b and 2b have much higher whiteness in terms of their lightness regardless of whether they are waste paper pulp or virgin pulp. By utilizing this, when absorbing urine, the colors of the core portions 1a and 2a can be exposed through the surface layers 1b and 2b.

As another example, the core portions 1a and 2a may be colored with a water-insoluble pigment or dye to give the above-mentioned distinguishable structure.

As still another example, the entire core portion 1a, 2a or the outer layer portion is colored with a water-soluble pigment or dye.
In this embodiment, the core part 1 is used when urine is hydrated.
The coloring of a and 2a infiltrates the surface layers 1b and 2b to expose the color of the core portion so that it can be distinguished after use and before use.
In the present invention, the core portions 1a, 2a and the surface layers 1b, 2b are darkened in the former, the latter is lightened in color, and the lightness is differentiated so that the color of the core portions 1a, 2a is passed through the surface layers 1b, 2b during absorption of urination. It discloses the concept of making it open to the public.

The present invention also has a core portion 1a, 2a and a surface layer 1
b and 2b are made of different materials and surface layers 1b and 2b are absorbed during urine absorption
The idea of allowing the colors of the core portions 1a and 2a to be exposed is disclosed. The surface layers 1b and 2b are formed of an inorganic material such as silica, zeolite, bentonite or the like in addition to organic fibers or powders thereof to impart water absorbency.

To restate one suitable example according to the above idea, the core portions 1a and 2a (pulp fibers) are positively colored with a pigment or a dye, and the surface layers 1b and 2b which are not colored as described above. By coating with (pulp fiber), a clear exposed color can be obtained, and pulp is easy to obtain and inexpensive, which enhances the marketability.

Further, the present invention is, as an embodiment, a treatment material comprising the above-mentioned absorbent material, that is, the core portions 1a, 2a and the surface layer 1b,
2b is formed of organic fiber or organic powder, and the above coloring pigment or coloring dye is formed of an organic coloring material so as to have a material structure suitable for wastewater treatment after flowing into a toilet.

Inorganic substances such as calcium carbonate, clay and silica are harmless and dissolve well in water. By adding a pigment containing these inorganic substances to the treatment material made of the above organic substance, weight addition can be properly performed and an exposed structure due to coloring can be formed.

[0024]

EFFECTS OF THE INVENTION According to the present invention, in the animal urinary disposal material comprising a water absorbent material, the core portion and the surface layer are made to have a multi-layer structure, or the core portion is darker than the surface layer. Based on the idea of using a colored multi-layer structure, we can provide the above-mentioned treatment material that allows the color of the nucleus to be exposed through the surface layer when absorbing urine, without using a conventional drug that changes the color by detecting pH of urination. In addition, it is possible to form the above-mentioned treatment material that can be accurately discriminated before and after use, and it is possible to enjoy the advantage that only the treatment material after use can be replaced. Further, good appearance can be imparted by the surface layer. Therefore, any material can be selected for the inside (core portion) as long as the function is not impaired.

Further, since the above object can be achieved by simply making the treating material to have the above-mentioned multi-layered structure, it can be commercialized without causing a harmful concern to the user as in the case of using a drug such as a urination reaction agent, Further, it is possible to provide a proper excrement disposal material even in the wastewater treatment after being flushed to the toilet.

In the present invention, urination includes defecation.
