Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sand substitute material that is used by filling the bottom of cages and the like when breeding laboratory animals and pets.

[Conventional technology]

For example, when experimental animals are kept in cages, they are often kept on sand spread inside the cage.
This sand gets contaminated with the excrement of the laboratory animals being kept, so it needs to be replaced every three days or so, and especially in facilities where a large number of laboratory animals are kept, the sand becomes contaminated with excrement etc. Labor costs were needed.

Moreover, depending on the experimental animal, the excrement from them may contain various pathogenic bacteria, and in such cases, the sand should originally be incinerated, but sand is a non-combustible material. Therefore, it was difficult to deal with it.

In view of these difficulties, we have developed materials for disposing of excrement from livestock, etc., which are made by forming paper into strings and then cutting them into appropriate sizes, or by cutting paper into appropriate sizes and rolling them up. 54-24945) and similar processing materials formed by drying small pulp lumps (Utility Model Publication No. 54-17675).
Although these conventional products have been developed and put into practical use, these conventional products have some inadequacies.

[Problem that the invention seeks to solve]

In other words, all of the conventional products mentioned above are granular and have high fluidity, and as the experimental animals move around in the cage, the thickness of the carpet becomes uneven, and the animals can easily dig up the cage, so the problem eventually occurs. This is because the bottom of the cage is exposed and animal excrement may adhere thereto.

Furthermore, due to the shape of the conventional products, that is, they are granular, they have a high scattering property, and in the case of animals that are frequently used in laboratory animals, animal excrement may be deposited on other cages or on the floor of the facility. There was also the drawback that the treatment materials contaminated with water were scattered.

In addition, the actual production of conventional products required numerous steps such as defibration and granulation, making them extremely costly.

[Means for solving problems]

The present invention was developed against the background of the above-mentioned circumstances, and is characterized by its structure being formed into a flat plate by cutting a fibrous sheet such as paper manufacturing residue into an appropriate size. be.

〔Example〕

Next, an example of implementation of the present invention will be explained with reference to the drawings.

1 is a unit of the sand substitute material of the present invention, which has a structure in which fibrous materials are laminated as a whole, has a rectangular flat plate shape, and has a size of about 5 x 5 x 2.5 mm. It's dry.

The material of the present invention can be manufactured by various methods, but for example, as shown in FIG. After drying, it is first cut into strips using a cutter with many parallel blades.

Next, the cutter is rotated 90° to cut the unit structure 1, thereby obtaining a large amount of the unit structure 1, and then drying the unit structure 1.

Incidentally, when the material is simply cut and dried as described above, the edges remain sharp, but if this is inconvenient, the edges may be chamfered using known means at the same time as the drying process.

On the other hand, the method of use is not different from conventional products; all you have to do is spread it on the bottom of the cage to an appropriate thickness.

[Effect]

The sand substitute material of the present invention, which has the above-mentioned features, has a structure in which fibers are laminated throughout, so it has excellent hygroscopicity and can be easily disposed of by flushing it into a household flush toilet or incinerating it. This makes it possible to

In addition, since the material of the present invention is formed into a square flat plate shape, the corners and ridge lines of each unit structure will catch on each other even when external force is applied, and therefore, the material has the property that fluidity is moderately suppressed. have.

〔effect〕

Therefore, when the above-mentioned material of the present invention is used.

Not only does it have the same effect as conventional products, it can extend the replacement cycle from about 3 days for sand to about 2 weeks, and it can be disposed of extremely easily after use. No matter how active the animals are or how much they try to dig up, the bottom of the cage will not be exposed or be scattered onto other cages or the floor of the facility. It can be treated using only the material of the present invention, and it also exhibits the unique effect that there is no risk of contaminating other cages, etc.

Furthermore, since the material of the present invention can be manufactured by the extremely simple method described above, mass production is possible.
Costs can be significantly reduced, and even if sterilization is required in advance, sterilization can be performed at the raw material stage, which has the advantage that this operation does not increase costs.

The above explanation is for the case where the material of the present invention is directly spread on the bottom of the cage, but the material of the present invention is placed in a suitably sized bag and the bag is placed on the bottom of the cage. In this way, the material of the present invention can be placed in cages and treated with the bag, making the work extremely simple. It is possible to prevent accidents that could result in injury. Moreover, the shape of this bag is of course not particularly limited, but if a rectangular bag that corresponds to the bottom of the cage is used, it will be easier to use the material of the present invention, and further,
If the bag is made of water-soluble fiber, the bag can be washed with water.
-It becomes something that can be flushed away.

[Other Examples]

In the above embodiments, the unit structure is square, but the shape of the material of the present invention is not limited to this, and any shape may be used as long as it is flat.

In addition, if a fibrous sheet such as papermaking residue, which is a raw material, is impregnated with an aqueous solution of baking soda, carbon dioxide gas will foam during drying, making the material of the present invention porous, that is, more hygroscopic than 2. can.

As described above, the present invention is particularly excellent as a sand substitute material for animal breeding.
