DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an animal cage.

[0002]

2. Description of the Related Art In recent years, the breeding of pets has become popular, and the tendency of breeding pets at home and traveling with pets has been increasing. Pet cages for keeping pets indoors and pet cages that are easy to carry have been devised and put to practical use.

[0003]

However, the biggest problems in raising animals are the animal odor and excrement odor, and the unpleasant pests that inhabit or accumulate in animals. The greatest solution to this is careful cleaning, but it is desired to reduce the number of times as much as possible.

[0004] It is an object of the present invention to provide an animal cage excellent in antibacterial, deodorant and insect repellent properties.

[0005]

Means for Solving the Problems In order to solve the above problems, the invention according to claims 1 to 3 is to attach an antibacterial agent to a floor member such as a litter sheet to at least realize antibacterial properties,
An antibacterial agent is kneaded in a constituent resin member, or an antibacterial agent is added to a coating material of a structural member. In addition, in order to realize anti- odor properties in addition to antibacterial properties, silver silica gel-based antibacterial compositions comprising silica gel carrying a silver thiosulfato complex salt and coating at least a part of the surface of the silica gel with a hydrolyzate of tetraalkoxysilane. The agent was adopted.

[0006] The invention of claim 4-6, further in order to achieve the insecticidal, impregnated with cockroaches, mites, etc. repellents on the floor member, such as bedding sheets, cockroaches, mites, etc. repellents in the resin constituting member Or a composition in which repellents such as cockroaches and mites are added to the coating material of the structural member. In the invention of claim 7 , a cockroach or mite repellent containing at least one of a transdermally effective repellent material such as cockroaches and mites and a gasified and transpirable repellent material such as cockroaches and mites is employed. I decided that.

[0007]

[Function] The surface of a component of an animal cage becomes dirty after being used for a while. That is, it is contaminated with microorganisms and becomes a place for bacterial growth. Therefore, according to the first to third aspects of the present invention, an antibacterial agent is attached to a floor member such as a litter sheet, the antibacterial agent is kneaded in a constituent resin member, or the antibacterial agent is contained in a coating material of a structural member. The addition inhibits bacterial growth in animal cages.
Moreover, silver that functions as an enzyme degradation inhibitor of urea and uric acid
The use of a silver silica gel-based antibacterial agent containing the compound exhibits not only an antibacterial effect but also an odor preventing effect, that is, an odor generating suppressing effect.

As a result of the analysis, it was found that the main cause of the odor in the animal cage was nitrogen-based waste discharged from the animal, that is, excrement scattered on floor members and the like, and decay of urine. Although excrement can be removed by physical means, man-hours are required to remove flying urine. The malodorous component is ammonia as shown in FIG. This ammonia is a germ (microorganism) of urea or uric acid, the main component in urine.
It was elucidated that it was produced by the decomposition reaction of the enzyme possessed. On the conventional ordinary floor material shown in FIG. 4, a decomposition reaction for producing ammonia proceeds.

On the other hand, according to the invention of claims 1 to 3 , the silver silica gel antibacterial agent is applied to the coating material of the floor member, the constituent resin member or the structural member, so that the main component in urine can be reduced. As a result of inhibiting the enzymatic decomposition reaction of a certain urea / uric acid into ammonia, an odor caused by ammonia is suppressed. FIG. 3 shows the mechanism of suppressing the odor of flying urine.

[0010] Enzymatic degradation of urea is hydrolysis by urease as shown in the chemical reaction formula 1. Conditions for promoting this reaction include temperature (0 to 60 ° C) and pH (6 to
9) and the presence of urease, which is an enzyme possessed by most resident bacteria in the surrounding environment. on the other hand,
Conditions for suppressing this reaction are a temperature and pH other than those described above and the presence of an inhibitor. Silver, along with copper and zinc, acts as this inhibitor.

Uricase, which is involved in the enzymatic decomposition of uric acid shown in the chemical reaction formula 2, is also reduced to copper and zinc.
Silver, along with lead, also functions as an inhibitor. Since uric acid to produce ammonia that cause odor eventually becomes urea decomposes, silver as inhibitors of uricase
Also acts to prevent odor.

Furthermore, the growth of various bacteria is suppressed by the original action of the antibacterial agent. When germs multiply, unpleasant pests such as cockroaches and mites also breed, and germs are brought in by breeding of the harmful pests. The antibacterial agent also suppresses the growth of the germs introduced in this way.
Moreover, according to the invention of claims 1 to 3, the use of a silver silica gel antibacterial agent having a low vapor pressure reduces the vapor pressure and the safety of silver, thereby reducing the safety to the human body and the non-pollution to the environment. can get.

Further, according to the inventions of claims 4 to 7 , by introducing repellents such as cockroaches and mites, antibacterial performance, deodorant performance and insect repellency are exhibited in synergy with antibacterial agents. This repellent for cockroaches, mites, etc.
Compared to insecticides such as mites, safety against the human body and environmental non-polluting properties are obtained. In particular, according to the invention of claim 7 , by employing a repellent material such as a cockroach / mite which has a transdermal effect,
The repellent penetrates from the antenna of the cockroach to be penetrated and the skin of the foot, and the repellent effect is exhibited. For example, if a gas repellent material such as a cockroach or mite that has a sustained release effect by microencapsulation is used, the effect of the repellent having a limited duration of effect can be extended by gasification.
