Abstract
A pet litter box characterized in that at least a part of the pet litter box is molded from a synthetic resin containing a fibrous component obtained by heating the xylem and/or leaves of a tree under reduced pressure with microwaves to remove at least a part of essential oil and moisture. With this pet toilet, it is difficult to generate malodor originating from excreta liquid or excreta, a good feeding environment is maintained, and running cost is reduced.
Description
Technical Field
The invention relates to a toilet for pets and a manufacturing method thereof.
Background
Conventionally, as pet toilets for treating excrement of pets such as cats and dogs, the following types are known: a structure (single-layer type) in which a excrement treatment material forming a toilet bowl, such as cat litter or toilet sand, is stored in a lower portion of the toilet main body; a structure (double layer type) in which the toilet main body is divided up and down by a urine-permeable partition layer such as a grill, the excrement treatment material is contained in an upper layer portion, and a urine absorber such as a urine absorbing pad made of, for example, a water-absorbent resin, plant fiber, pulp, etc., is contained in a lower layer portion as needed; the toilet body is divided up and down by a urine permeable partition layer such as a grill, the excrement treatment material is stored in an upper portion, and a urine absorber such as the urine absorbing pad is stored in a tray in a lower portion for use (system type).
In these pet toilets, it is convenient to use a system type in which the excrement treating material stored in the upper portion allows urine excreted by the pet to pass through quickly, the passing urine falls down to the lower portion through the liquid passing holes of the grill, and the falling urine can be positively absorbed by the urine absorber of the tray stored in the lower portion.
In the pet litter box of the system type, odor such as excreta liquid in a tray disposed below the grill may volatilize outside through the grill, and may cause odor. If cat litter or the like is laid on the upper surface of the grid, odor can be blocked, but the cat has a habit of stirring the excrement treatment material with the foot after excretion, and therefore, the excrement treatment material is stirred after excretion, and the excrement treatment material is scraped off to expose the grid, and there is a possibility that excrement liquid or the like volatilizes to the outside through the exposed portion.

These trees may be combined in a plurality.
A method of heating the xylem and/or leaf of the above tree, preferably the xylem and leaf, under reduced pressure using microwaves to remove at least a part of essential oil and moisture is called a reduced pressure drying method. The reduced pressure drying method is a method for removing water and essential oil contained in a raw material by utilizing the property of directly heating water molecules by microwaves.
The reduced pressure drying method can be performed using, for example, a microwave distillation apparatus described in International publication No. WO2010/098440 or the like. In the reduced pressure drying method, the pressure in the distillation tank may be set to 1 to 95kPa, preferably 5 to 80kPa, and particularly preferably 10 to 60 kPa. The steam temperature at this time is 40 to 100 ℃. Among the distillation components produced, the oily component can be used as an essential oil for other purposes, for example, for nitrogen oxide removers, fragrances, and the like.
In the reduced pressure drying method, the xylem and/or leaf of the tree is preferably heated by microwaves to remove at least a part of the essential oil and the moisture, and then the drying step for removing the moisture at normal pressure is preferably performed. The drying temperature and drying time are not particularly limited, and may be, for example, about 1 to 5 hours at 50 to 80 ℃. The content of the essential oil component to be left is 0.01 to 10% by mass, preferably 0.1 to 5% by mass. The residual moisture is 1 mass% or less.
The thus obtained fibrous component is solid and exhibits excellent deodorizing effect. Although there are many unclear reasons for the deodorizing effect of the cellulosic component, in the present case, it is assumed that a part capable of adsorbing malodor is generated in the lignin structure or the cellulose structure from which a part of the essential oil is removed, from the viewpoint of the wooden structure in which cellulose is fixed to lignin or the essential oil.
In addition, although the moisture content of the fibrous component is almost removed, the essential oil component is not completely removed, but a part of the essential oil component contained in the xylem and/or leaf of the tree is removed, and a part of the essential oil component remains in the fibrous component.
Furthermore, the essential oils remaining in the fiber components are preferably low in volatility and/or non-volatile. This is because the lower the volatility, the longer the period of time the essential oil function (for example, deodorizing function and/or fragrance function) is exerted. In addition, the essential oil component preferably contains a component having a relatively large molecular weight. This is because the larger the molecular weight is, the more difficult it is to volatilize. When extracting essential oil from the xylem or the like of a tree, it is preferable to extract essential oil having a smaller molecular weight and/or being easily volatilized, and therefore, the material tends to have essential oil having a lower volatility and/or a larger molecular weight remaining. The essential oil component remaining in the material preferably has a low content of monoterpenes and more contains sesquiterpenes, diterpenes or tetraterpenes. When the ratio of terpenes having a large molecular weight such as sesquiterpenes and diterpenes is large, deodorizing effects and/or aromatic effects can be exhibited for a long period of time, and deodorizing effects and nitrogen oxide removing effects against various malodors caused by acidic, basic and neutral malodorous substances can be exhibited. Examples of the malodor substances include ammonia, methyl mercaptan, hydrogen sulfide, methyl disulfide, trimethylamine, acetaldehyde, propionaldehyde, n-butyraldehyde, isobutyraldehyde, n-valeraldehyde, isovaleraldehyde, isobutanol, ethyl acetate, methyl isobutyl ketone, toluene, styrene, xylene, propionic acid, n-butyric acid, n-valeric acid, isovaleric acid, 3-mercapto-3-methyl-1-butanol, and the like.
Since deodorizing properties of the fibrous component are continued for a long period of time, it is preferable that the fibrous component contains an essential oil having low volatility and/or an essential oil having no volatility. The fibrous component preferably contains an essential oil having a large molecular weight.
Preferably, the fibrous component contains an essential oil such as monoterpenes and sesquiterpenes. Examples of the monoterpenes include α -pinene, β -pinene, camphene, tricyclone, myrcene, β -phellandrene, bornyl acetate, δ -3-carene, terpinene, and limonene.
Examples of sesquiterpenes include β -caryophyllene and sabinene.
The essential oil remaining in the cellulosic component preferably has a low content of monoterpenes and more contains sesquiterpenes, diterpenes and/or tetraterpenes. When the proportion of terpenes having a large molecular weight such as sesquiterpenes and diterpenes is large, the fibrous component can maintain excellent deodorizing properties for a long period of time.
The fibrous component has excellent deodorizing properties and exhibits excellent deodorizing effects on odors generated from the feces and urine of a toilet for pets, particularly cats. The fibrous component has excellent deodorizing property against an odor originating from at least 1 selected from the group consisting of ammonia, hydrogen sulfide, methyl mercaptan, acetic acid, toluene and formaldehyde, and more preferably has excellent deodorizing property against an odor originating from at least 1 selected from the group consisting of ammonia, hydrogen sulfide and methyl mercaptan.
Further, since the fibrous component is a natural product obtained from a tree as a plant, there is no risk to pets. In addition, the deodorizing effect can be maintained for a long period of time because it is difficult to volatilize.
The fibrous component is preferably finely pulverized so that the average particle diameter is 1 to 500. Mu.m. If the average particle diameter is 1 μm or less, the particles may be aggregated during molding and may be difficult to mold, and if the particle diameter is more than 500 μm, the nozzle of the injection molding machine may be clogged and uniform mixing may be difficult, so that the deodorizing effect may be poor. More preferably, the average particle diameter is 5 to 400. Mu.m. The average particle diameter and the maximum particle diameter are values expressed by median particle diameter (D50) obtained by measuring particle size distribution by a laser diffraction and scattering particle size distribution measuring apparatus.
The method of precision grinding is not particularly limited, and only a conventionally known precision grinder may be used. Examples of the fine pulverizer include a turbo mill, a jet mill, a bead mill, a blade mill, a motor mill, a rotor mill, a cutter mill, a disc mill, and a vibration mill.
The amount of the fibrous component contained in the synthetic resin is not particularly limited, and for example, the fibrous component is 0.01 to 20 parts by mass, preferably 0.1 to 10 parts by mass, relative to 100 parts by mass of the synthetic resin.
The method of adding the fibrous component to the synthetic resin is not particularly limited, but kneading is preferable because the amount of the plastic raw material to be used can be reduced, the environmental load can be reduced, the deodorizing effect is high, and the long-term maintenance can be performed.
In the case of kneading a fibrous component into a synthetic resin, a master batch pellet containing the fibrous component is prepared, and the master batch pellet is mixed with a ribbon blender or the like, and molded by a general molding method for a synthetic resin. Since the synthetic resin and the fibrous component can be effectively mixed and the fibrous component can be heated in the synthetic resin to smoothly transfer a part of the essential oil and the moisture in the fibrous component to the synthetic resin side, the porous property of the fibrous component can be promoted and the deodorizing property can be improved, a molding method of the synthetic resin using an extruder is preferable. Examples of such a molding method of the synthetic resin include extrusion molding, injection molding, inflation molding, blow molding, and the like.
The synthetic resin may be blended with other functional components such as silica gel, zeolite, activated carbon, clay mineral, photocatalyst (titanium dioxide) perfume, deodorant, and antibacterial agent. In the case of mixing them, they may be mixed according to a conventionally known method.
The method for producing the pet litter box of the invention is not particularly limited as long as at least a part of the pet litter box can be formed using the synthetic resin, and examples thereof include a method in which a synthetic resin composition containing a synthetic resin and a fibrous component obtained by removing at least a part of essential oil and moisture from a tree raw material containing fir tree is supplied to a kneading apparatus, and the synthetic resin composition is heated and melt-kneaded and then supplied to a mold. Examples of the mold include a container as a whole, a container as a lower part, a permeable separator such as a grid, a tray, and a part of the wall surface of the container.
The fibrous component is heated by the synthetic resin in a molten state in the above-described manufacturing process. By this heating, at least a part of the essential oil and moisture contained in the fibrous component is transferred to the synthetic resin side, and the fibrous component has a finer porous structure, and the essential oil component having more excellent deodorizing property is concentrated in the fibrous component. Therefore, the fibrous component can more effectively exhibit excellent deodorizing properties due to the essential oil by forming the fine pores of the fibrous component.
At least a part of the pet litter box of the invention is formed of a resin containing a fibrous component having an excellent deodorizing effect for a long period of time. Therefore, the pet litter box of the invention can deodorize the foul smell generated from the excrement liquid or the excrement discharged into the pet litter box, and can prevent the foul smell from leaking out of the pet litter box main body for a long period of time.
The pet litter box of the invention is suitable for deodorizing malodor generated from excreta liquid or excreta of pets such as cats and dogs, and is particularly suitable for deodorizing malodor generated from excreta liquid or excreta of cats having a unique odor.
Hereinafter, an example of the pet litter box of the invention will be described with reference to the drawings. These pet litter boxes are typical examples of various types, and the shape of the pet litter box of the invention is not limited to these.

Examples (example)
Hereinafter, examples of the present invention will be described, but the present invention is not limited to these examples.
(production of fibrous component)
Branches of 90kg of fir in a leaf-bearing state were crushed using a crushing crusher (manufactured by KYB) to obtain small pieces of tree raw material having a size of about 10 to 20 mm. Tree raw materials are supplied into a distillation tank of a microwave distillation apparatus.
Then, the pressure in the distillation tank was maintained at a reduced pressure of about 15kPa, and the tree material was irradiated with microwaves for 1 hour. The vapor (essential oil and water) generated was removed from the distillation tank by a vacuum pump to obtain a processed object of fir. The amount of the obtained fir treatment was 68kg.
The obtained fir processed material was pulverized by a jet mill using a high-speed air flow to obtain a fibrous component in which at least a part of essential oil and water were removed from the tree raw material. When the fibrous component was observed with an optical microscope, the inclusion of the green or blue-colored portion was confirmed to include the leaf-derived material.
By adjusting the treatment conditions of the pulverization treatment of the processed Costus sequoia, a solid fibrous component A having an average particle diameter of 7 μm was produced.
Examples 1 to 5 and comparative example 1
The resin composition containing the polypropylene and the fibrous component A in the predetermined amounts shown in Table 1 was fed to an extruder, melt kneaded at 180℃and then extruded from the extruder, and the extruded resin composition was cooled to prepare a test piece having a cubic shape of 100mm at one side.
The deodorizing properties (deodorizing effect in feeling) of the obtained test pieces were measured according to the following fields, and the results are shown in table 1.
(deodorization effect on feel 1)
An air bag with a tap having a capacity of 10 liters was prepared. 1 test piece and about 30ppm ammonia gas were supplied into the air bag and sealed, and left to stand at 20℃for 300 minutes. Then, the cock of the air bag was opened, and the air bag was directly smelled, and evaluated according to a six-level odor intensity method. The number of the measurement subjects was 10, and each measurement subject evaluated the sensory deodorizing effect on each test piece. The arithmetic mean of the evaluations of the test pieces was calculated.

As described above, synthetic resins containing cellulosic components obtained by heating the xylem and/or leaves of trees with microwaves under reduced pressure to remove at least a part of essential oils and moisture make it difficult to generate malodors derived from ammonia and cat litter smell.
Therefore, it is found that when the synthetic resin is used for at least a part of the pet litter box, it is difficult to generate a malodor originating in excrement or urine of a pet, and a good feeding environment can be maintained.
Example 7
A resin composition containing 100 parts by weight of polypropylene and 0.6 part by weight of fibrous component a was fed into an extruder, melt kneaded at 180 ℃, and then molded into a grid corresponding to 21 in fig. 3 by an injection molding machine. The grating is provided instead of the grating of the conventional system type pet litter box, cat litter is put on the grating, and the absorber is put in the tray to be used as the litter box of the cat for about 3 days, so that the cat can be restrained from having the fecaluria and the stink.
