Description

  The present invention relates to an excrement disposal material set for pet animals that is preferably used in a toilet for cats, dogs, and other pet small animals.

  Conventionally, this type of excrement disposal material set for pet animals has been used in so-called two-layer toilets, which are composed of, for example, a plastic tray and a saw-like container disposed on the tray (for example, Patent Document 1).

Patent Document 1 discloses a pet excrement in which a low water-absorbing excrement disposal material is disposed on a slat-like container, and a hydrolyzable sheet containing a disinfectant and a deodorant is disposed below the slat-like container. A treatment tool is disclosed.
According to the pet excrement disposal tool of Patent Document 1, since the excrement disposal material itself has low absorbability, the excreted urine quickly passes between the excrement disposal materials and through the sag-like container, It is going to be easily absorbed by the water-decomposable sheet placed below the container.

However, in the pet excrement disposal tool of Patent Document 1, when the cat sand disposed on the slat-like container is packed in a bag or the like and thrown away, the cat sand that has absorbed the cat's urine is scattered, It stuck and was difficult to throw away.
Moreover, the excrement disposal material used for this pet excrement disposal tool uses synthetic resin to adjust its water absorption, which increases the manufacturing cost.
Furthermore, the excrement disposal material absorbs cat urine to some extent because its entire surface is low in water absorption, but when its water absorption ability is reduced, malodor may occur. In addition, when the tray is shallow, there is a drawback in that the cat is always sanded after the stool, so there are too many splashes and the periphery of the tray is soiled.

JP 2003-180182 A

  The subject of this invention is providing the excrement disposal material set for pet animals which can be used for the toilet of a 1 layer type or a 2 layer type, can discard an excrement disposal material easily, and can suppress a smell.

The present invention solves the above problems by the following means. In addition, in order to make an understanding easy, although the code | symbol corresponding to the Example of this invention is attached | subjected and demonstrated, it is not limited to this.
Invention of Claim 1 is arrange | positioned on the bottom part of a toilet container (1), a super absorbent sheet (10) with high water absorption and antibacterial property, and the super absorbent sheet (10), and a liquid passage The passage sheet (20) having a property and the passage sheet (20) are arranged on the surface, and a part (30a) of the surface thereof has low water absorption, and a part (30b) other than the low water absorption has water repellency. An excrement disposal material set for pet animals comprising a certain excrement disposal material (30).

  The invention of claim 2 is characterized in that in the excrement disposal material set for pet animals according to claim 1, the excrement disposal material (30) has a water repellency in 30 to 70% of its surface area. This is an excrement disposal material set for pet animals.

  The invention of claim 3 is the excrement disposal material set for pet animals according to claim 1 or claim 2, wherein the excrement disposal material (30) has a liquid passage rate of 95% or more. This is a featured excrement disposal material set for pet animals.

The invention of claim 4 is the excrement disposal material set for pet animals according to any one of claims 1 to 3, wherein the excrement disposal material (30) is a powdery zeolite of 85 to 95 weights. Part, a granulated product of a mixture containing 5 to 15 parts by weight of a powdery binder, the granulated product having a particle size and length of 3.5 to 5.5 mm, and a bulk density of 0.7 g / cm ^3. This is a pet animal excrement disposal material set characterized by the above.

(1) Since the excrement disposal material set for pet animals of the present invention has an excrement disposal material in which a part of its surface has low water absorption and a portion other than low water absorption is water repellent, When the urine of the pet animal comes into contact with the water-repellent part of the excrement disposal material, the urine is not absorbed by the excrement disposal material, but quickly passes through the passage sheet and is easily absorbed by the high water absorption sheet. In addition, when the urine of a pet animal comes into contact with the portion of the excrement disposal material that has low water absorption, even if the urine becomes droplets due to surface tension, the urine is absorbed by the portion of low absorption, and thus Furthermore, urine hardly remains on the surface of the excrement disposal material, and the odor can be suppressed.
Moreover, since the passage sheet with liquid permeability is arranged on the high water absorption sheet, even if the toilet container is a single layer type or a two layer type, the high water absorption sheet, the passage sheet, the excrement disposal material, Furthermore, the excrement disposal material can be easily discarded in a state where it is wrapped with a passing sheet.

(2) Since the excrement disposal material has water repellency in 30 to 70% of its surface area, the water absorption of the excrement disposal material can be partially reduced.

(3) Since the liquid passage rate of the excrement disposal material is 95% or more, most of the pet animal's urine quickly passes through the excrement disposal material, and droplets are formed on the surface of the excrement disposal material. Absorbed urine is absorbed.

(4) The excrement disposal material is a granulated product of a mixture containing 85 to 95 parts by weight of powdered zeolite and 5 to 15 parts by weight of powdered binder, and this granulated material has a particle size and length of 3 0.5 to 5.5 mm and the bulk density is 0.7 g / cm ³ or more, the granulated product is large in particle size and can increase the liquid passage rate, and the powdered zeolite is hardened by a strong pressure. Therefore, it is possible to reduce the water absorption of the powdered zeolite, and since it is tight and heavy, the powder does not fly so much that it is not scattered by the cat sand and spilled out of the toilet container.

  The object of the present invention is to provide an excrement disposal material set for pet animals that can be used in a 1-layer or 2-layer toilet, and can easily discard the excrement disposal material and suppress odor. Placed on the bottom of the superabsorbent sheet with high water absorption and antibacterial properties, placed on the superabsorbent sheet, insole net with liquid permeability, and placed on the insole net, This is realized by providing cat sand with a part of the surface having low water absorption and a part other than the low water absorption having water repellency.

Hereinafter, the present invention will be described in more detail with reference to the drawings and the like.
FIG. 1 is a view showing Example 1 of a pet animal excrement disposal material set according to the present invention. FIG. 1A is a cross-sectional view, and FIG. 1B is a top view.
A pet animal excrement disposal material set (hereinafter referred to as a treatment material set) 100 includes a highly water absorbent sheet 10, an insole net 20, a cat sand 30 as an excrement disposal material, and the like. In the following, a case where the treatment material set 100 is used in a so-called single-layer pet toilet 50 that does not use a saw-like container or the like will be described.

  The super absorbent sheet 10 is disposed at the bottom of the toilet container 1 and has high water absorption, antibacterial properties, and deodorizing properties (see FIG. 2, details will be described later). The super absorbent sheet 10 has a size of, for example, 30 × 45 cm and covers the bottom of the toilet container 1. The toilet container 1 is a plastic tray.

  The insole net 20 is disposed on the superabsorbent sheet 10 and has liquid permeability (see FIG. 3, details will be described later). The insole net 20 has a size of, for example, 60 × 60 cm, is larger than the bottom of the toilet container 1, covers the edge of the toilet container 1, and is easy to grasp.

  The cat sand 30 is an excrement disposal material and is laid on the insole net 20 and has low water absorption, antibacterial properties, and deodorizing properties. The cat sand 30 is a granulated product, and its water absorption is adjusted by spraying a water repellent on a part of its surface and applying a strong pressure when granulating (see FIG. 4, details). Will be described later).

FIG. 2 is a view showing the super absorbent sheet 10. 2A is a cross-sectional view, and FIG. 2B is a bb cross-sectional view of FIG. 2A.
The highly water absorbent sheet 10 includes a waterproof film 11, water absorbent papers 12a and 12b, a nonwoven fabric 16 disposed on the water absorbent paper 12a, and a mixture disposed between the water absorbent papers 12a and 12b.
The waterproof film 11 is made of, for example, polyethylene, and covers the peripheral edge portion from the back surface of the superabsorbent sheet 10 so that urine does not leak and urine does not leak into the bottom of the toilet container 1. The water-absorbing papers 12a and 12b are for uniformly distributing and sandwiching the mixture.

  The mixture is composed of the superabsorbent resin 13, the pulp 14, the carbon material 15, and the antibacterial agent. The mixture contains 14 g of superabsorbent resin 13, 40 g of pulp 14, 8 g of carbon material 15, and 1 g of antibacterial agent inside the 30 × 45 cm superabsorbent sheet 10. The content is about 5 times that of a normal super absorbent sheet. For example, cat urine is absorbed up to 2500 mL (the amount of urination for cats is 5-7 days). The action can suppress the growth of bacteria and suppress the smell.

  The highly water-absorbent resin 13 is a resin that can maintain a solid state even when it absorbs 50 to 2000 times its own weight of water. For example, a saponified copolymer of a vinyl ester and an ethylenically unsaturated carboxylic acid or derivative thereof , Starch and acrylic acid graft polymer, polyacrylic acid cross-linked product, vinyl alcohol and acrylic acid copolymer, polyacrylonitrile partial hydrolyzate, carboxymethyl cellulose cross-linked product, polyethylene glycol cross-linked product, chitosan salt Pullulan gel can be used.

  The carbon material 15 is a carbide obtained by treating a mineral having a layered crystal body under special conditions and then firing it at a high temperature for a long time. Fine carbon adheres between the surface and the interlayer, and by ionic bonds, It is a substance that strongly adsorbs ammonia, mercaptans, fatty acids, etc., which are elements of odor.

The super absorbent sheet 10 is embossed after the mixture is uniformly disposed on the absorbent paper 12b, the absorbent paper 12a and the nonwoven fabric 16 are disposed thereon, and these are laminated. And the waterproof sheet 11 is adhere | attached so that the back surface and peripheral edge of the super absorbent sheet 10 may be covered.
Since the mixture is embossed by being sandwiched between the water-absorbing papers 12a and 12b, the mixture will not be offset when the high water-absorbing sheet 10 is normally used.

FIG. 3 is an explanatory view showing the insole net 20. FIG. 3A is a schematic top view, and FIG. 3B is a side view.
The insole net 20 includes warps 21 and wefts 22 and the like. The warp yarns 21 and the weft yarns 22 are made of water-repellent polyester or the like, are overlapped so as to be substantially orthogonal to each other, and are bonded at the contact points 23 thereof. The warp yarn 21 and the weft yarn 22 have a thickness of 500 denier.
The insole net 20 has a mesh 24 formed by bonding a plurality of warp yarns 21 and weft yarns 22 at contact points 23. The mesh 24 has a size of about 2 × 4 mm and is smaller than a granulated product of cat sand 30 described later, and the cat sand 30 does not spill from the mesh 24.
Further, the insole net 20 is not frayed unlike the case where the warp yarn 21 and the weft yarn 22 are bonded to each other at the contact point 23, unlike the case where the insole net 20 is knitted.

FIG. 4 is an explanatory view showing the cat sand 30. 4A is a perspective view, and FIG. 4B is a partially enlarged view.
The cat sand 30 is a granulated product of a mixture containing 90 parts by weight of powdered zeolite and 10 parts by weight of powdered binder. This granulated product has a cylindrical shape with a particle size and length of 3.5 to 5.5 mm, and a bulk density of 0.7 g / cm ³ .
As the powdery binder, for example, polyvinyl alcohol (PVA), carboxymethyl cellulose (CMC), methyl cellulose (MC), starch, pullulan, gelatin and the like can be used.

The cat sand 30 is granulated by a so-called vertical extrusion granulator equipped with a large number of holes having a diameter of 4.0 mm and a screen having a thickness of 10 mm. Since this screen has a large hole diameter of 4.0 mm, the particle size of the granulated material can be increased. Furthermore, since the thickness is as thick as 10 mm, when granulating by passing through the hole of the screen, A strong pressure is applied to the granulated product, and the bulk density of the granulated product can be 0.7 g / cm ³ . The screen preferably has a hole diameter of 3.5 to 4.5 mm and a thickness of 6.0 to 13 mm, and within this range, a granulated product having a large particle size and bulk density can be obtained. Can do.

The cat sand 30 is hydrolyzed together with the powdered binder and hardened by a strong pressure by the above granulator, so that the water absorption of the powdered zeolite can be reduced. Because it is tight and heavy, the powder is less likely to fly, and even when the cat hangs on the sand, it will not spill out of the toilet container 1 and get dirty.
The cat sand 30 has a low water absorption portion 30a and a water repellent portion 30b on the surface thereof. The low water absorption part 30a is a part having low water absorption because the powdered zeolite is tightly tightened during granulation. The water repellent part 30b is a part that becomes water repellent by being sprayed with a desired water repellent after being granulated. The water repellent part 30 b occupies 30 to 70% of the surface area of the cat sand 30.

  The cat sand 30 can adjust the liquid passage rate by adjusting the proportion of the water repellent part 30b in the surface area. For example, when the thickness is about 5 cm, the liquid passage rate is 95% or more. . For this reason, even if cat urine contacts the surface of cat sand 30, 30 to 70% of the surface area is water-repellent, so this urine passes quickly through cat sand 30 and insole net 20, It is absorbed by the super absorbent sheet 10.

  The cat sand 30 is, for example, about 3.0 L (about 2.7 kg) laid on the toilet container 1 and actually used on a cat (urine urination of about 80 mL per day) for about 40 days. However, there was almost no smell of urine.

Below, the usage method of the processing material set 100 is demonstrated.
First, the super absorbent sheet 10 is laid on the bottom of the toilet container 1. Next, the insole net 20 is uniformly covered on the highly water absorbent sheet 10. Then, the cat sand 30 is placed on the insole net 20 to a height of 3 to 5.0 cm.
The treatment material set 100 is used for a one-layer pet toilet 50. As described above, the cat sand 30 can be used for about 40 days, and the super absorbent sheet 10 can be used for 5 to 7 days.

FIG. 5 is a diagram illustrating a state when the super absorbent sheet 10 and the cat sand 30 are replaced.
The owner holds the insole net 20 by hand and lifts the cat sand 30 in a wrapped state, and then replaces the super absorbent sheet 10 with a new one. The insole net 20 has a size of about 60 × 60 cm and can withstand a weight of about 5.0 kg or more.

  In addition, the owner needs to replace the cat sand 30 with a new one before the water absorption capability of the cat sand 30 is impaired. Therefore, when the owner starts using the treatment material set 100 for about 40 days, as described above, the owner grabs the insole net 20 by hand and lifts the cat sand 30 together, and then packs the cat sand 30. Throw away in a pack. At this time, the cat sand 30 absorbs the urine of the cat, but since the cat sand 30 is wrapped in the insole net 20, the cat sand 30 does not adhere to the owner's hand, and the cat sand 30 is clean and easy. Can be thrown away.

Thus, according to the processing material set 100 of Example 1, there are the following effects.
(1) The superabsorbent sheet 10 has a superabsorbent resin 13, pulp 14, carbon material 15, and antibacterial agent content higher than usual, and is 30 × 45 cm in size for 5 to 7 days. Can maintain antibacterial and deodorizing properties.
(2) The insole net 20 is composed of warp yarns 21 and weft yarns 22 and is adhered by an adhesive at a contact 23, so that it is not frayed and used for a long time unlike ordinary knitted fabrics. can do.
(3) The insole net 20 is not torn even when the cat sand 30 is lifted. Further, since the cat sand 30 is wrapped in the insole net 20, the cat sand 30 does not adhere to the owner's hand, The cat sand 30 and the super absorbent sheet 10 can be replaced with peace of mind.
(4) Since the cat sand 30 has the water-repellent portion 30b on the surface thereof, when the cat's urine comes into contact with the water-repellent portion 30b, the urine is not absorbed by the cat sand 30 and quickly passes through the insole net 20. Since it passes, it can be easily absorbed by the super absorbent sheet 10.
(5) Since the cat sand 30 has the low water absorption portion 30a on the surface thereof, when the urine of the cat comes into contact with the low water absorption portion 30a, the urine adheres to the surface of the cat sand 30 and drops into droplets due to the surface tension. Even if it becomes, since this droplet is absorbed, urine hardly remains on the surface of the cat sand 30, and the smell of urine can be suppressed.

FIG. 6 is a diagram showing Example 2 of the treatment material set 100 according to the present invention. 6A is a cross-sectional view showing a state where the treatment material set 100 is used, and FIG. 6B is a view showing a state where the superabsorbent sheet 10 is replaced.
Here, the treatment material set 100 is used in a two-layer pet toilet 50 </ b> A including a toilet container 1 and a slat-like container 40. The squirrel container 40 is disposed inside the toilet container 1 and has a plurality of holes at the bottom thereof to allow cat urine to pass therethrough.

As illustrated in FIG. 6A, the treatment material set 100 includes a super absorbent sheet 10 disposed at the bottom of the toilet container 1, an insole net 20 disposed on the slat-like container 40, and an insole net 20. And cat sand 30 laid on the top.
In the pet toilet 50A in which the treatment material set 100 is used, as shown in FIG. 6B, after the owner holds the insole net 20 with his hand and lifts the cat sand 30 in a wrapped state, Sand 30 can be thrown away and is hygienic.

Thus, the following effects are obtained by using the treatment material set 100 for the two-layer pet toilet 50A.
(1) The cat sand 30 can be replaced with the insole net 20 without using the slat-like container 40. At this time, even if the cat's urine remains in the sword-like container 40, the owner does not need to touch the sword-like container 40, and thus the cat's urine does not adhere to the hand.
(2) The cat urine quickly passes through the cat sand 30 and the insole net 20, and further passes through the slat-like container 40 and is absorbed by the super absorbent sheet 10, so that the cat sand 30 and the super absorbent sheet 10 As long as the water absorption and antibacterial properties are maintained, the urine odor can be suppressed.

(Modification)
The present invention is not limited to the embodiments described above, and various modifications and changes are possible, and these are also within the equivalent scope of the present invention.
(1) In the treatment material set 100, the water-repellent agent is sprayed using the cylindrical cat sand 30 so that a part of the surface thereof becomes the water-repellent portion 30b. Alternatively, the surface may have a plurality of protrusions.
FIG. 7 is a view showing a modification of the cat sand 30.
The cat sand 30A has a spherical shape as shown in FIG. 7A, and is granulated by, for example, a bread granulator. The cat sand 30A has a low water absorption portion 30c and a water repellent portion 30d on the surface thereof.
As shown in FIG. 7B, the cat sand 30B has a shape having a plurality of protrusions on its surface, and has a low water absorption portion 30e and a water repellent portion 30f on its surface.
In this way, the cat sands 30A and 30B, like the cat sand 30, hardly retain urine on the surface, and can suppress odor.

(2) In the treatment material set 100, the insole net 20 is used. However, if the toilet is a single layer type, the super absorbent sheet 10 is stacked, and the cat sand 30 is directly placed on the super absorbent sheet 10. It is possible to lay down and not use the insole net 20.
FIG. 8 is a diagram illustrating a modified example of the treatment material set.
The treatment material set 100A is used for a one-layer pet toilet using the toilet container 1A, and includes, for example, super absorbent sheets 10a, 10b, 10c, cat sand 30 and the like.
The toilet container 1A is a tray. The super absorbent sheets 10a, 10b, 10c are stacked on the bottom of the toilet container 1A. The cat sand 30 is directly laid on the super absorbent sheet 10a disposed on the outermost surface side.
In this way, after the treatment material set 100A uses the superabsorbent sheet 10a for 5 to 7 days, the owner pulls the end of the superabsorbent sheet 10a and takes out the superabsorbent sheet 10a. Can be used for 5 to 7 days in that state. The super absorbent sheets 10a, 10b, and 10c can be easily taken out from the toilet container 1A if a string is attached to the end thereof.

(3) In the treatment material set 100, when the super absorbent sheet 10 is replaced, as shown in FIG. 5 and FIG. 6B, the owner holds the insole net 20 by hand and lifts the cat sand 30 together. However, the present invention is not limited to this, and a bag shape (pouch-like shape) may be formed by attaching and pulling a string around the periphery of the insole net 20. In this way, the owner can wrap the cat sand 30 with the insole net 20 by pulling the string, and can easily replace the super absorbent sheet 10.
(4) Although the toilet containers 1 and 1A are trays (shallow bottom containers), the present invention is not limited to this and may be, for example, deep bottom containers made of various materials.
