Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pet stool bed used for receiving feces and urine of pets kept indoors such as dogs and cats.

[0002]

2. Description of the Related Art Heretofore, a zeolite-based adsorption deodorant or a bentonite-based adsorption deodorizer has been used as a pet toilet floor of this type.

[0003]

The above-mentioned zeolite-based adsorption deodorant has a problem of odor during defecation because it has a small water-absorbing ability in feces and urine, and the bentonite-based adsorption deodorant is solid in the stool. However, it requires a large amount of an adsorbing deodorant, which is uneconomical, and when the adsorbing deodorant after use is discarded, there is a problem of environmental pollution.

[0004]

[Means for Solving the Problems] The present invention provides a pet toilet floor (3) comprising silica gel (1) which is a mixture of organic acid-containing silica gel (1A) and silver ion-containing silica gel (1B). .

The silica gel used in the present invention is usually one having a pore size of about 20 to 200Å and a particle size of about 0.02 to 10 mm, and it is desirable that the pore size has a distribution as wide as possible within the above range. Organic acid-containing silica gel and silver ion-containing silica gel are mixed with the silica gel. Examples of the organic acid-containing silica gel include oxalic acid, malonic acid, succinic acid, maleic acid, fumaric acid, glycolic acid, lactic acid, β
-Silica gel in which an organic acid having a desirably low volatility such as oxy acid, malic acid, tartaric acid, citric acid, and tannic acid is added and mixed, and the silver ion-containing silica gel is an inorganic silver salt such as silver chloride or silver nitrate, or silver acetate. , Silver propionate, silver stearate and the like, which is a silica gel mixed with a compound capable of releasing silver ions such as an organic silver salt, wherein the organic acid-containing silica gel is colored red or blue, for example. It is desirable that the ion-containing silica gel be colored green, for example. If the silica gel is colored in this way, the approximate blending ratio can be visually discriminated, and there is an advantage that coloring due to manure is inconspicuous. However, the coloring does not limit the present invention. In the silica gel, the organic acid-containing silica gel usually contains 3 to 10% by weight, and the silver ion-containing silica gel usually contains 1 to 5% by weight.

[0006]

The silica gel used in the toilet bed of the present invention has the reversibility that it adsorbs water when the humidity is high and releases it when the humidity is low. Therefore, when the feces bed of the present invention receives manure, it immediately absorbs the water contained in the manure containing the odor component to adsorb and remove the odor, and releases only the water when the humidity is low. Therefore, the silica gel used in the toilet bed of the present invention takes a long time to reach the adsorption saturation and, as a result, has a long life and can be regenerated. Further, the organic acid-containing silica gel contained in the above silica gel adsorbs and neutralizes ammonia, which is one of the odorous components of manure, to deodorize it, and the silver ion-containing silica gel suppresses the propagation of various bacteria on the feces bed. In addition, since the main component of silica gel is silicic acid, it is easily assimilated into soil, and there is no risk of environmental pollution even if it is discarded after use.

The results of the performance test of silica gel used in the toilet bed of the present invention are shown below. The performance test was carried out using silica gel having an average pore size of 60Å and an average particle size of 2 to 5 mm. 1. Water absorption / desorption test Silica gel is immersed in water to make it saturated, and after draining, laying the silica gel to a predetermined thickness on an iron plate and measuring the weight change of the silica gel when left alternately in the sun and indoors to determine the water content The release state was observed. The result is shown in FIG. In the figure, graph 1 shows a case where silica gel is spread to a thickness of 7 mm, and graph 2 shows a case where silica gel is spread to a thickness of 17 mm.
Shows the case where silica gel is spread to a thickness of 30 mm. As is clear from FIG. 1, in low humidity, silica gel rapidly releases water to regenerate its water absorbing ability. 2. 0.1 ml each of silica gel, silica gel mixture, waste paper powder, bentonite, and wood flour were charged into a 1-liter flask.
A solution or gas containing each of the odor components is injected so as to have a blank concentration as shown in (1), and after 30 minutes, the concentration of the remaining odor in the flask is measured with a Kitagawa type detector tube to calculate an odor removal rate (%). The results are shown in Table 1.

[Table 1] As is clear from Table 1, the silica gel mixture has a better deodorizing ability than other samples regardless of the type of odor component.

【Example】

Example 1 As shown in FIG. 2, the silica gel (1) is a container.
Filled in (2) to form a toilet bed (3). The silica gel
(1) is a pore size range of 20 to 200Å and a particle size range of 0.02 to
10 mm, containing 6% by weight of organic acid-containing silica gel (1A) and 3% by weight of silver ion-containing silica gel (1B), the organic acid-containing silica gel (1A) being colored red and blue, The ion-containing silica gel (1B) is colored green. The container (2) has dimensions of 50 × 50 cm and a depth of 25 cm, and the silica gel (1) is placed in the container (2) in an amount of about 2 kg.

When the above-mentioned toilet bed (3) was placed in the room where one adult cat was kept, odor was detected in the room only after about 25 to 30 days. Silica gel containing organic acid for comparison
When a toilet bed containing silica gel not containing (1A) and silver ion-containing silica gel (1B) was used, odor was detected after 15 days. When a stool bed containing a bentonite-based adsorptive deodorant was used, the generation of odor was detected after 3 days. Therefore, the toilet bed (3) of the present invention requires only about half the amount of silica gel containing no organic acid-containing silica gel (1A) or silver ion-containing silica gel (1B). Only about 1/9 of the amount used.

[Embodiment 2] As shown in FIG. 3, a gauge (4)
The floor (5) is 25 × 25 cm in length and width and 2 cm in depth, and about 100 g of the silica gel (1) used in Example 1 is evenly spread on the floor (5) to form a toilet floor. Bird 3 at the gauge (4)
The generation of odor was detected only after about 6 to 7 days when the animals were bred, and the generation of odor was detected after about 4 to 5 days when two hamsters were bred. As a comparison, when the bentonite-based adsorption deodorant was used, the same day odor was detected in both birds and hamsters.

[0011]

Therefore, according to the present invention, it is possible to prevent the generation of odor due to the feces and urine of pets for a long period of time, and to obtain the insect repellent effect.
