Toilet sand for animals

Abstract: Since the present invention is composed of required component capable of changing in color with which a daily product and so on are impregnated, painted or printed, such daily product is convenient in daily life by indicating a contact between the required component and urine and so on.

Description: The present invention relates to sand for pet animals, as is known for example from US-A-3,978,818. Background of the Invention It is an object of the present invention to provide daily goods which is a toilet sand for animals capable of detecting the conditions and so on of the animals by detecting the moisture for the purpose of conducting appropriate treatment. Disclosure of the Invention A daily product, which is a toilet sand for animals, of the present invention consists of material impregnated, painted or printed with required ink capable of changing in color depending on moisture. Therefore the daily product changes the material in color upon contact between the moisture of excreta and so on from the animal and so on and the required ink present in the product, whereby detecting urinary PH, protein, glucose and blood qualitatively or quantitatively, indicating the condition of the animal and being helpful to conduct various treatments appropriately. Brief Description of the Drawing. Fig.1 is a perspective view of an embodiment of the sands for a pet toilet of the present invention. Preferable Embodiments of the Present Invention The present invention is further described based on the examples with referring to the appended figure. Fig.1 is a perspective view of an embodiment of sand 22 for a pet toilet of the present invention. These embodiments consist of the materials which are impregnated, painted or printed with the required component capable of changing color of the materials by the required water. Such materials consists of, for example, paper. The required component may be any reagent which can be used to detect qualitatively or quantitatively urinary PH, protein, glucose, blood and so on as well as other agents such as sterilizer, perfume, deodorant agents and the like. The required components are not limited to the above. Furthermore going into detail, the ink is used for the detecting layer, and consists of bromothymol blue, cellulose and derivatives of the cellulose which are dispersed or dissolved in organic solvent and change in color at the detecting layer. In the embodiment, the toilet sand 22 for animals 2 in Fig. 1 is impregnated with the required color-developing component, which develops the color at only part of the sand 22 to where the urine of the pets touches, and the sand of the part can be discarded. Fig. 1 is perspective view of an embodiment of the sand 22 for pet toilet of the present invention. These embodiments consist of the materials which can be impregnated, painted or printed with the required ink which changes the color by the required water. The required ink can be composed by dispersing or dissolving indicators for detecting urinary PH, protein, glucose, blood, urobilinogen or ketone body together with cellulose and derivatives thereof in organic solvent. In the embodiment mentioned above, the indicators for urinary PH is bromothymol blue. In some conventional indicators, the color may fade within several minutes after the change of the color by detecting the required water. The time point for judgment of the change of the color is not limited to the time right after the change. In order to make the indicators into ink, the indicators mentioned above is dispersed or dissolved together with cellulose and derivatives thereof in organic solvent and the mixture forms a detecting layer which changes the color. The cellulose, hydroxypropyl cellulose, methylcellulose, ethyl cellulose, hydroxypropylmethyl cellulose and carboxy- methyl cellulose in the cellulose and derivatives thereof have high ability of sensitivity. The solvent depends on the method of printing. For example, although aromatic hydrocarbones can not be used in flexography in view of the characteristic of the plate, the solvent should preferably selected because of the solubility of the resin and stability of the solubility and dispersion of the indicator. The indicators are dispersed or dissolved in organicsolvent such as methanol, ethanol, toluene and sodium hydroxide. Usefulness in Industrial Field Since the present invention has the required component capable of changing in color with which daily products are impregnated, painted or printed, the present invention provides convenience in daily life by detecting the contact between the required component and the urine and so on when the required component contacts with the urine and so on.

Claims: Toilet sand for animals consisting of materials which are impregnated, printed or painted with an ink composed by bromothymol blue dispersed or dissolved in an organic solvent. Toilet sand according to claim 1 wherein the organic solvent is ethanol. Toilet sand according to claim 1 or 2 characterized in that the ink contains cellulose or derivatives thereof.
