Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a urine absorbing material that can be suitably used for absorbing urine of a pet such as a cat.

[0002]

[Prior art]

 Conventionally, there are urinary absorption materials called so-called cat sand for absorbing urination of pets such as cats, which are mainly made of minerals and those made of paper. Zeolite is one of the minerals. Granules composed of bentonite and other porous minerals are used. Further, as the material made of paper, as shown in FIG. 6, for example, a urine absorbing material 30 obtained by rolling paper into a substantially spherical shape having a diameter of about 2 to 3 mm, and as shown in FIG. There are a urine absorbing material 31 which is rounded and has a water absorbing polymer attached to the surface thereof, and a urine absorbing material 32 which is obtained by cutting pulp while extruding pulp into a right cylindrical shape as shown in FIG.

Since the urine absorbing material made of the above minerals is incombustible, it is impossible to treat it as a combustible waste after absorbing urine. In addition, according to the experiments conducted by the inventor of the present invention, the amount of water absorbed per 10 g of the absorbent is small, for example, 6.4 to 14.4 g, and therefore a large amount of the urine absorbing material must be discarded by one urination. However, it has the problem of being uneconomical.

Further, the urinary absorption materials 30 and 31 obtained by rolling the paper or pulp and the urine absorption material 32 formed by extruding the pulp have a low absorption rate because the pulp is relatively hard. As in the prior art shown in FIG. 7, in the urine absorbing material 31 in which the water absorbent polymer is attached to the surface of the pulp core, the absorbent polymer on the outer peripheral surface absorbs the water and solidifies, so that the water inside is absorbed. Although it cannot be sufficiently impregnated and its water absorption is higher than that of the urine absorbent material using the above minerals, there is a problem that it is uneconomical because the amount of urine absorbent material discarded by one urination is large. .

[0005]

[Problems to be solved by the device]

 Therefore, an object of the present invention is to provide a urine absorbing material that can improve the economical efficiency by increasing the water absorbing capacity.

【Example】

 FIG. 1 is a perspective view of a strip 3 which constitutes the urine absorbent material 1 according to one embodiment of the present invention, and FIG. 2 is a sectional view of the strip 3. For example, a urine absorbing material 1 used for urine disposal of a pet such as a cat is composed of a plurality of minute strips 3. The strips 3 are housed in a container 4 as shown in FIG. The strip 3 therein absorbs the urine of the pet such as the cat to treat the urine.

The strip 3 is composed of an absorbent body 5 in which a water-absorbent polymer 8, a deodorant 9 and an antibacterial agent 10 are mixed in cotton-like pulp, and the thickness direction of the absorbent body 5 (vertical direction in FIGS. 1 and 2). It is composed of two water-soluble porous sheets, tissues 6a and 6b, which are laminated on each other. The textures 7a and 7b are formed on each of the tissues 6a and 6b by embossing, and the adhesive strength between the absorbent body 5 and the surfaces of the tissues 6a and 6b facing the absorbent body 5 is increased by the engagement of the fibers. Has been done.

The cotton-like pulp is mainly crushed newspaper waste paper or computer waste paper, and has a fiber length of 0.5 to 1.0 mm, for example.

The water-absorbing polymer 8 is composed of sodium acrylate or potassium acrylate.

As the deodorant 9, fine particles obtained by concentrating sap containing components such as phytoncide, which are generally well known, are used. The fine particles generate a scent of trees even in a dry state, and when dissolved by water such as urine, they neutralize main components of odor such as ammonia and promote evaporation of scent components of trees. The fragrance is enhanced. That is, when the absorber 5 absorbs water, the effect of absorbing the main component of odor such as ammonia is enhanced, and the scent of the tree is also strengthened.

In general, urine of humans and cats has no odor at the time of urination under normal conditions. The causes of odor are as follows. That is, the smell of ammonia is a general abnormality of urine, and ammonia has a specific odor, but normal room urine fresh at room temperature contains only a small amount of ammonia, and thus has no smell of ammonia. However, urine contains a large amount of urea and a large amount of NH ₄ ⁺ , and when urea is decomposed by urease-producing bacteria such as Proteus to produce ammonia, and NH ₄ ⁺ is converted to ammonia by heat from the outside. An ammonia odor is generated when it changes. In addition, urinary tract infection caused by urease-producing bacteria may excrete freshly excreted urine with an ammonia odor.

Further, when a large amount of protein is decomposed by bacteria, it gives off a rotting odor, and in the case of ketonuri, it gives a peculiar odor to urine.

In addition, the sap has an antibacterial action, and the antibacterial effect suppresses the bad odor generated by the decomposition of urea and protein, which are the source of the odor, by various bacteria, and the scent component suppresses the odor of urination from the surroundings. Suppresses the stench of packaging.

As another embodiment of the present invention, activated carbon, zeolite and ceramic may be used as the deodorant 9 to enhance the deodorizing effect.

Further, the antibacterial agent 10 has, for example, a new quinolone drug, a pyridone carboxylic acid drug, or a nitrofuran derivative drug, or hinokitiol (3- and 5-isopropyl tropolopol), which has an antibacterial action against the urease-producing bacterium. (E.g.), a tree containing an antibacterial component such as Aomori Hiba crushed product.

The strip 3 has a predetermined size, for example, a length L of about 3 to 10 mm, a width W of 3 to 8 mm, and a thickness T of about 1 to 5 mm. When such a strip 3 is housed in the container 4 and a pet such as a cat urinates, it is contained in the strip 3 of the portion 11 absorbing the urination as shown by the phantom line in FIG. Since the water-absorbing polymer 8 gels to increase its adhesiveness and becomes a so-called lump, it is possible to easily discard only the portion 11 that has absorbed the urine.

FIG. 4 is a diagram showing a manufacturing process of the urine absorbing material 1. Newspaper and computer waste papers are defibrated and / or deinked to form flocculent pulp. The cotton-like pulp is crushed and agitated by the crusher 13 to be a cotton-like pulp having a desired unit volume weight. The water absorbing polymer 8, the deodorant 9 and the antibacterial agent 10 are mixed with the cotton-like pulp, and the mixture is supplied from the supply means 16 onto the tissue 6b so as to have a uniform thickness. Further, the tissue 6a is placed on the cotton-like pulp, and the cotton-like pulp is sandwiched between the tissues 6a and 6b and compressed by a pair of press rolls 14 to form a wide plate-like body 17. To do. At this time, the cotton-like pulp and each of the tissues 6a and 6b are pressurized and humidified, and the water-absorbing polymer 8 contained in the absorber 5 serves as a binder to bond the fibers to each other by hydrogen bonding to form the plate-like body 17 Is formed. Further, at this time, by performing embossing, the fibers of the cotton-like pulp and the fibers of the tissues 6a and 6b are engaged with each other, and the tissues 6a and 6b are not separated from the absorbent body 5. Further, the unit volume weight of the cotton-like pulp and the densities of the tissues 6a and 6b are adjusted so that the unit area weight per 1 mm in thickness of the plate-like body 17 is 150 to 300 g / m ^2. It

The plate-like body 17 formed as described above is cut into a desired size by the cutter blade 15 of the cutting device, and the strip 3 of the urine absorbent material 1 can be obtained.

As described above, since the urine absorbing material 1 is formed into the strips 3 by cutting the plate-like body 17 having a low unit area weight per 1 mm in thickness, that is, having a low density, Since the absorption rate of urine due to the action of osmotic pressure is high and a large amount of urine can be absorbed, it can be suitably used as a urine absorption material for pets such as cats. Further, since the deodorant 9 and the antibacterial agent 10 are mixed in the absorbent body 5, it is possible to suppress a bad odor and impart an antibacterial effect. In addition, by using a tree component as the deodorant 9 and the antibacterial agent 10, a natural scent is introduced into a pet such as a cat placed in an artificial environment so that the rhythm of living in nature can be improved. It helps to regain the stress and eliminate stress to create an optimal environment to stay healthy.

Table 1 shows the result of comparison between this example and the conventional comparative example.

[0027]

[Table 1]

However, in Table 1, the amount of water absorbed was obtained by placing 10 g of the sample in a conical shape on the sharpness of a mesh, pouring 40 ml of water for 1 minute, tilting the sharpness at a 30 degree angle, and leaving it for 1 minute. , The value obtained by weighing and subtracting the initial sample weight. The value with the symbol "*" was not saturated and was a value obtained by sprinkling 100 ml of water for 1 minute.

FIG. 5 is a perspective view showing a strip 3a of the urine absorbing material 1a according to another embodiment of the present invention. The strip 3a is formed by laminating a plurality of plate-like bodies 17 composed of the absorbent body 5 and the tissues 6a 1 and 6b, which are formed in the same manner as in the above-described embodiment, three in this embodiment, and the one side surface 18a 1, 18b, It is formed by cutting so that only 18c is joined.

As described above, since the strip 3a has a structure in which a plurality of plate-like bodies 17 are laminated, the surface area is large, and thus a larger amount of urine can be absorbed and the water absorption speed is also increased. .

As still another embodiment of the present invention, a plurality of strips 3 of the embodiment shown in FIGS. 1 to 4 and a plurality of the strips 3 shown in FIG. 5 are laminated and one side surface 18a to 18c is joined. The urine absorbing material may be formed by mixing with the strip 3a.

As yet another embodiment of the present invention, a component that changes color due to the adhesion of water to the above-mentioned strips 3 and 3a, for example, cobalt (II) chloride anhydrate, is added to the cotton-like pulp to form the absorber 5. You may form. Cobalt (II) chloride anhydrous reacts with water and changes its color from blue to red. Therefore, it is possible to easily and clearly distinguish the strips 3 and 3a in which water has been absorbed by urination from those that do not absorb water, and to accurately grasp the discarded part that has absorbed urine, It is possible to prevent wasteful consumption of the urinary absorption materials 1 and 1a by discarding only the waste.

In addition, the urine absorption material 1, 1a is formed by using two tissues 6a, 6b formed in advance by adding a component that is discolored by the adhesion of water, for example, cobalt (II) chloride anhydrate. Good.

[Effect of device]

 According to the present invention, the urine absorbing material has a plate-like body having a predetermined size, which is obtained by sandwiching an absorbent body, which is a mixture of a water-absorbing polymer, a deodorant, and an antibacterial agent in cotton-like pulp, between two water-soluble porous sheets. Since it is cut into strips to form strips, water such as urine can penetrate into the absorber without solidifying on the porous sheet, increasing the absorption amount and generating odors from urination. Can be minimized or eliminated. Further, it is possible to suppress the reproduction of bacteria such as urease-producing bacteria. Further, since the plate-like body has extremely low density, large voids are formed between the fine fibers constituting the cotton-like pulp, and the cotton-like pulp having such large voids is sandwiched by the porous sheet. In addition, it is possible to prevent the fibers of the cotton-like pulp from scattering, and it is possible to store a large amount of water due to the voids. In addition, the strips of the portion that has absorbed water such as urination increase in stickiness due to the attachment of water and adhere to each other to form a lump, so that only the portion to which water has adhered can be easily taken out. . At this time, since each strip can absorb a large amount of water, the amount of strips to be discarded can be reduced and the economical efficiency can be improved.

Further, according to the present invention, since a component that changes color due to the adhesion of water is added to the strip, the color tone of the component in the strip changes due to urination, and it is easy and clear whether urination is present or not. Can be identified. Therefore, it becomes possible to accurately grasp the portion to be discarded that has absorbed urine, and it is possible to prevent wasteful consumption of the strip.
