[0002]

2. Description of the Related Art Conventionally, when raising pets indoors,
A pet toilet is used, and the pet toilet is used.
Is configured to accommodate waste such as pet droppings and urine
Have been. This pet toilet is made of the dirt from the waste.
Bacteria cause dirt and foul odors. So,
Spray antibacterial spray on the pet toilet in advance,
It is conceivable to prevent the generation of the germs.

The antimicrobial agent used in the antimicrobial spray is
Thus, for example, an antibacterial spray composition as disclosed in JP-A-63-250325 has been proposed. The antimicrobial spray composition is configured to include an antimicrobial zeolite, alcohol and a propellant,
For example, polyethylene, polypropylene, vinyl chloride, A
By spraying on a thermoplastic or thermosetting resin such as BS resin, nylon, polyester or the like, the surface thereof can be coated, and antibacterial, antifungal and antialgal properties can be added to these resins.

[0004]

[Problems to be Solved by the Invention] However, according to the test results of the present inventors, the resin forming the pet toilet for pets
Spray coated antibacterial agent on product surface
Even when the surface of the resin product was washed with distilled water or tap water, it was found that no sterilization effect was observed as shown in the following table.

[0005]

In other words, the test method used to obtain the test results shown in this table is to dilute a bacterial solution which had been statically cultured in a meat extract broth medium for 24 hours with a phosphate buffer solution to 100 times, 0.2 ml thereof was dropped on the sample in the petri dish. Thereafter, a membrane filter (0.2 μm) was cut into a size of 2.5 cm × 5 cm, coated on the sample to which the bacterial solution was dropped, and cultured at 37 ° C. Twenty-four hours later, 30 ml of a phosphate buffer was added, and after shaking,
One ml was taken out, and the number of surviving bacteria was measured by the pour plate method using SCDLP agar medium.

[0006] As a result, as shown in Table 1, when sprayed, the sterilization rate was 0% for both staphylococci and Escherichia coli, and it was clear that no sterilization effect was observed. This is presumed that even if the surface of the molded article was simply coated with the antibacterial agent, there was no physical bond between the antibacterial agent and the molded article.

Therefore, as disclosed in, for example, JP-A-2-133449, by mixing an antibacterial agent into a plastic extruded product, a physical binding relationship between the antibacterial agent and the molded product is generated. Have been proposed to ensure antimicrobial properties. However, when the antibacterial agent is mixed into the molded article in this way, the amount of the antibacterial agent used per molded article is greatly increased as compared with the case of coating. Therefore, in consideration of safety and heat resistance, when using the silver based inorganic antibacterial agent in molded articles, silver based inorganic antibacterial agent due to being expensive, forced a significant cost I will. Moreover, when a silver-based inorganic antibacterial agent is mixed into the resin,
Since the transparent resin becomes opaque such as discoloration due to the mixing of the antibacterial agent, the antibacterial property cannot be secured by mixing the silver-based inorganic antibacterial agent into the transparent molded article.

[0008] The present invention is intended such was made in view of the conventional problems, in a region having a transparent magnetic
Maintains antibacterial effect after cleaning while ensuring lightness
It is an object of the present invention to provide a pet toilet that can be used .
