Description
本発明は、猫や犬などの動物のトイレ用敷材として使用される動物用のトイレ砂に関する。 The present invention relates to animal litter used as a litter for animals such as cats and dogs.
室内で飼われている猫や犬などの動物用トイレとして、プラスチック製の容器にいわゆる「猫砂」と呼ばれる粒状物からなるトイレ砂が入れられたものが、使用されている。動物が排泄した尿などの排泄物は、このようなトイレ砂によって吸収される。飼い主は、この尿や便で汚れたトイレ砂を便などと一緒に容器から取り除き、取り除いた分に応じて新しいトイレ砂を補充する。しかし、猫は排泄後にトイレ砂を足でかき混ぜる習性があり、尿や便などが付着したトイレ砂が足に付着してしまうことがある。しかも、汚れたトイレ砂が拡散されてしまうため、汚れた部分のみを完全に除去することは困難なものである。 As toilets for animals such as cats and dogs kept indoors, toilets made of granular materials called so-called “cat sand” are used in plastic containers. Excrements such as urine excreted by animals are absorbed by the toilet sand. The owner removes the toilet sand soiled with urine and stool from the container together with the stool, and refills with new toilet sand according to the removed amount. However, cats have the habit of stirring toilet sand with their feet after excretion, and toilet sand with urine, feces, etc. may adhere to their feet. Moreover, since the dirty toilet sand is diffused, it is difficult to completely remove only the dirty part.
このようなトイレに使用されるトイレ砂としては、鉱物系のゼオライトや川の砂、あるいは液体を吸収すると固まるベントナイト、粉砕パルプ等を固めて粒状に成形したセルロースなどがある。しかし、ゼオライトや川の砂などは尿を吸収するものではなく、また、ベントナイトやパルプ等は吸収力が劣っている上に脱臭力もない。しかも、動物、特に猫の排泄物は悪臭が強く、トイレを設置してある部屋全体に臭いが漂い、その後始末は不快感が伴うものであった。 Examples of toilet sand used in such toilets include mineral-based zeolite and river sand, bentonite that hardens when liquid is absorbed, and cellulose that is formed by solidifying pulverized pulp and the like. However, zeolite, river sand, etc. do not absorb urine, and bentonite, pulp, etc. are inferior in absorption power and have no deodorizing power. Moreover, the excrement of animals, particularly cats, has a strong bad odor, and the whole room where the toilet is installed has an odor.
このような問題を解決するものとして、多孔質の耐水シリカゲルから構成され、強い脱臭力及び吸収力を持たせたトイレ砂がある（例えば、特許文献１参照）。また、トイレ砂に撥水性を有する素材を用い、尿などの水分を吸収する吸液シートと併用することによって臭いの発生を抑制したものがある（例えば、特許文献２参照）。 As a solution to such a problem, there is toilet sand made of porous water-resistant silica gel and having strong deodorizing power and absorbing power (see, for example, Patent Document 1). In addition, there are materials that suppress the generation of odor by using a water-repellent material for toilet sand and using it together with a liquid-absorbing sheet that absorbs moisture such as urine (for example, see Patent Document 2).
しかし、特許文献１に記載のトイレ砂は、粒径を小さくすることで砂の表面積と空隙を減らして効率的に尿を吸収するために、粒径が２ｍｍから６ｍｍと小さい。また、含水率を低く設定して吸収速度と最大吸収量を増やすために、９０℃から１２０℃で乾燥した後の含水率が３重量％以下に調整されている。このように、前記トイレ砂は、吸収速度が速く、排泄された尿などをすばやく吸収できるようになっている。しかし、大量に尿を吸収したシリカゲルがトイレ容器内に残ることになるので不衛生であり、また、悪臭が発生する原因となる。 However, the toilet sand described in Patent Document 1 has a particle size as small as 2 mm to 6 mm in order to reduce the surface area and voids of the sand and efficiently absorb urine by reducing the particle size. Further, in order to increase the absorption rate and the maximum absorption amount by setting the moisture content low, the moisture content after drying at 90 ° C. to 120 ° C. is adjusted to 3% by weight or less. As described above, the toilet sand has a high absorption speed and can quickly absorb excreted urine and the like. However, since silica gel that has absorbed a large amount of urine remains in the toilet container, it is unsanitary and causes a bad odor.
また、特許文献２に記載のトイレ砂を構成する粒状物は吸水性を有さないため、粒状物を通過せずに粒状物表面に尿などが残存してしまった場合には、この残存してしまった尿が腐敗し、悪臭が発生するという問題がある。更に、流れるほど大量ではない便の水分などはトイレ砂を通過することが出来ないため、便の臭いが残ってしまうというおそれもある。このようなことから、トイレ砂の汚れた部分をペットの排泄の度に捨てたり、１、２週間に一度の割合でトイレ砂を全て取り替える必要があり、また、砂のみならず吸液シートも新しいものに交換しなければならないために、大量のゴミを出してしまうという問題もある。 Moreover, since the granular material which comprises the toilet sand of patent document 2 does not have water absorption, when urine etc. remain on the granular material surface without passing through the granular material, this residual There is a problem that the urine that has fallen rots and a bad odor is generated. Furthermore, since the stool moisture or the like that is not so large as to flow cannot pass through the toilet sand, the stool smell may remain. For this reason, it is necessary to discard the dirty part of the toilet sand every time the pet is excreted, or to replace all the toilet sand once every one or two weeks. There is also a problem that a lot of garbage is taken out because it must be replaced with a new one.
本発明は、このような問題を解決するためになされたものであり、その目的は、トイレ砂と吸液シートとの双方を用いる二重構造のトイレにおいて、排泄物の液体の大部分を速やかに吸液シートへ移動させるための液通過性を有し、かつ、通過し得なかった水分については時間の経過と共にトイレ砂中に吸収されるような吸収性を有する、長期間使用可能な動物用トイレ砂を提供することである。 The present invention has been made to solve such a problem, and its purpose is to quickly remove most of the waste liquid in a double-structure toilet using both toilet sand and a liquid absorbent sheet. A long-term animal that has liquid permeability for moving to a liquid-absorbent sheet, and absorbs moisture that could not pass through the toilet sand over time. To provide toilet sand.
より具体的には、本発明は以下のようなものを提供する。 More specifically, the present invention provides the following.
（１） 複数の粒状物から構成される動物用トイレ砂であって、前記複数の粒状物には、撥水性を有する第１粒状物と、吸水性を有する第２粒状物と、が含まれる動物用トイレ砂。 (1) Animal litter composed of a plurality of granular materials, wherein the plurality of granular materials include a first granular material having water repellency and a second granular material having water absorption. Animal toilet sand.
（１）の発明によれば、トイレ砂を、撥水性を有する第１粒状物と、吸水性を有する第２粒状物とからなるものとすることによって、粒状物の吸収速度を抑制することが可能となる。即ち、液体はまず、粒状物同士の間にある隙間を縫ってすばやく通過していく。そして、粒状物表面に残った液体は、時間の経過と共に吸水性を有する第２粒状物中に吸収されていく。このため、トイレ砂の表面に水分が残留しにくく、さらさらとした状態を維持しやすくなっている。 According to the invention of (1), the toilet sand is made of the first granular material having water repellency and the second granular material having water absorption, thereby suppressing the absorption rate of the granular material. It becomes possible. That is, the liquid first passes quickly by sewing a gap between the granular materials. And the liquid which remained on the granular material surface is absorbed in the 2nd granular material which has water absorption with progress of time. For this reason, moisture hardly remains on the surface of the toilet sand, and it is easy to maintain a smooth state.
（２） 前記第１粒状物の含有量は、前記第２粒状物の含有量よりも多い（１）に記載の動物用トイレ砂。 (2) The animal litter according to (1), wherein the content of the first granular material is greater than the content of the second granular material.
（２）の発明によれば、第１粒状物の含有量を、第２粒状物の含有量よりも多くしたことによってトイレ砂の表面に水分が残留しにくく、よりさらさらとした状態を維持しやすくなっている。第１粒状物の含有率は９０％以下（容積比）であることが好ましく、５０％以上であることが更に好ましい。含有率を５０％以上とした場合には、吸水部分が撥水部分に接して液残りしにくくすることができる。 According to the invention of (2), since the content of the first granular material is larger than the content of the second granular material, moisture hardly remains on the surface of the toilet sand, and a more smooth state is maintained. It has become easier. The content of the first granular material is preferably 90% or less (volume ratio), and more preferably 50% or more. When the content rate is 50% or more, the water absorption portion can be in contact with the water repellent portion and the liquid can hardly remain.
（３） 前記第２粒状物の表面積は、前記第１粒状物の表面積よりも大きい（１）又は（２）に記載の動物用トイレ砂。 (3) The animal litter according to (1) or (2), wherein a surface area of the second granular material is larger than a surface area of the first granular material.
（３）の発明によれば、第２粒状物の表面積を、第１粒状物の表面積よりも大きくしたことによってトイレ砂の表面に水分が残留しにくく、より一層さらさらとした状態を維持しやすくなっている。この点撥水加工が施されていない第１粒状物の面積の方が大きいと液体を通過させずに吸収してしまうため、さらさらとした状態を維持することができなくなってしまうからである。また、第１粒状物粒状物の形状は、球状、ペレット状、打錠タイプ（薬形状）であることが好ましく、その大きさは直径（長さ）４ｍｍ〜１４ｍｍであることが好ましい。 According to the invention of (3), since the surface area of the second granular material is larger than the surface area of the first granular material, moisture hardly remains on the surface of the toilet sand, and it is easy to maintain a more smooth state. It has become. This is because if the area of the first granular material that has not been subjected to the point water repellent treatment is larger, the liquid is absorbed without passing through, so that the smooth state cannot be maintained. Moreover, it is preferable that the shape of a 1st granular material granular material is spherical shape, a pellet shape, and a tableting type (drug shape), and the magnitude | size is preferable that the diameter (length) is 4 mm-14 mm.
（４） 吸水性を有する吸液シートと併用されるものである（１）から（３）いずれかに記載の動物用トイレ砂。 (4) The animal litter according to any one of (1) to (3), which is used in combination with a liquid-absorbing sheet having water absorption.
（４）の発明によれば、トイレ砂と吸液シートとを併用し、排泄物の液体を速やかに吸液シートに吸収させることにより、においの発生を抑えると共に、トイレ砂のさらさらとした状態を維持することが可能となっている。この吸液シートとは、本発明に係るトイレ砂を通過した液体を吸収するためのものであり、トイレ底面部に敷かれる。このようなトイレ砂と吸液シートを併用するために使用するトイレとしては、トイレ砂を貯留するトイレ砂収納部と吸液シートを敷くための吸液シート収納部との二重構造からなっているものであって、トイレ砂収納部の底面部に複数の空孔を有するものが好ましい。 According to the invention of (4), the toilet sand and the liquid absorbent sheet are used in combination, and the liquid of the excrement is quickly absorbed into the liquid absorbent sheet, thereby suppressing the generation of odor and making the toilet sand dry. It is possible to maintain. This liquid absorbing sheet is for absorbing the liquid that has passed through the toilet sand according to the present invention, and is laid on the bottom surface of the toilet. As a toilet used to use such toilet sand and liquid absorbent sheet together, it consists of a double structure of a toilet sand storage part for storing toilet sand and a liquid absorbent sheet storage part for laying the liquid absorbent sheet. It is preferable to have a plurality of holes in the bottom of the toilet sand storage part.
（５） 前記複数の粒状物全体の液通過率は、５０％以上である（１）から（４）いずれかに記載の動物用トイレ砂。 (5) The animal litter according to any one of (1) to (4), wherein a liquid passage rate of the plurality of granular materials as a whole is 50% or more.
（５）の発明によれば、粒状物の液通過率を５０％以上としたことによって、トイレ砂を排泄物の水分がより通過しやすく、特に、吸液シートと併用して用いた場合に特に有効である。尚、粒状物の液通過率は８０％以上であることがより好ましい。 According to the invention of (5), when the liquid passage rate of the granular material is 50% or more, the moisture of the excrement is more easily passed through the toilet sand, particularly when used in combination with the liquid absorbent sheet. It is particularly effective. The liquid passage rate of the granular material is more preferably 80% or more.
以上述べたように、本発明に係る動物用トイレ砂によれば、液通過性が高く、残存液体も時間と共に吸収することができる。このためトイレ砂を使用時の状態に維持しやすく、排泄物の悪臭の発生も防止することが可能である。 As described above, according to the animal litter according to the present invention, the liquid passing property is high, and the remaining liquid can be absorbed with time. For this reason, it is easy to maintain toilet sand in the state at the time of use, and generation | occurrence | production of the malodor of excrement can be prevented.
また、本発明の動物用トイレ砂は、長期間繰り返し使用することが可能であるため廃棄量が少なくてすみ、掃除の手間が少なく、かつ、経済的である。 Further, the animal litter according to the present invention can be used repeatedly for a long time, so that the amount of waste can be reduced, the amount of time and effort for cleaning is small, and it is economical.

本発明の動物用トイレは、図１（Ａ）に示すように、第１粒状物及び第２粒状物から成るトイレ砂を貯留する箱状のトイレ砂収納容器１０と、前記収納容器１０の下方に位置し出し入れ自在に組み込まれた吸液シート１４を収納する吸液シート収納容器１１と、前記トイレ砂収納容器１０の上部に側面を覆うようにして設置された側面カバー１２とを主要素として構成されている。前記トイレ砂収納容器１０の底面部１０２は、複数の空孔１０４を有している。この空孔１０４は、多面体又は円形であることが好ましく、トイレ砂１３が抜け落ちない大きさであることが好ましい。
As shown in FIG. 1 (A), the animal toilet of the present invention has a box-shaped toilet
図１（Ｂ）に示すように、トイレ砂収納容器１０の底面部１０２の上面には、トイレ砂１３を１０ｍｍ以上の厚さで敷いて層状に敷設する。尚、対象動物が猫の場合、猫が排泄物を隠そうとしてトイレ砂１３を掻くため、トイレ砂１３の厚さは、２０ｍｍ以上であることがより好ましい。また、吸液シート収納容器１１内に、吸液シート１４を敷設する。
As shown in FIG. 1 (B), on the upper surface of the
図２は、本発明のトイレ砂１３及び吸液シート１４を収納したトイレの断面を示す。動物が排泄した時には、液体１５はまず、トイレ砂１３の間を通ってトイレ砂収納容器１０の底面部１０２に設置されている空孔１０４を通過し、吸液シート収納容器１１に敷かれている吸液シート１４に吸収される。そして、前記トイレ砂１３中に残った液体１５は、時間の経過と共に前記トイレ砂１３中に吸収されていく。
FIG. 2 shows a cross section of a toilet in which the
本発明に係るトイレ砂を用いて液通過実験を行なった。実験方法は以下の通りである。まず、スノコ容器の中に、深さ３０ｍｍで本発明に係るトイレ砂（試料１）、市販のトイレ砂（試料２）、及び表面の全部が撥水性のトイレ砂（試料３）を敷き詰めた。次に、あらかじめ重量を測定したペットシートの上に上記検体を入れたスノコ容器を置いた。そして高さ約２０ｍｍの位置から、２０ｃｃの生理食塩水を約１０秒で滴下した。その後１５秒ほど放置し、吸水したペットシートの重量を測定した。また、液通過量を計算した。 A liquid passage experiment was performed using the toilet sand according to the present invention. The experimental method is as follows. First, toilet sand according to the present invention (sample 1), commercially available toilet sand (sample 2), and toilet sand (sample 3) whose entire surface was water-repellent were spread in a drainboard container. Next, a slatted container containing the specimen was placed on a pet sheet whose weight was measured in advance. Then, 20 cc of physiological saline was dropped from about 20 mm in about 10 seconds. Then, it was allowed to stand for about 15 seconds, and the weight of the absorbed pet sheet was measured. Moreover, the liquid passage amount was calculated.
その結果を表１に示す。表１から明らかなように試料１及び試料３の場合、試料２よりも５％程度液通過量が増加したが、しかし、試料３の場合は水滴が砂に残ってしまった。試料１の場合、液通過量は２〜４％の増加率にとどまるが、水滴残りが少ないことが示された。 The results are shown in Table 1. As apparent from Table 1, in the case of Sample 1 and Sample 3, the liquid passage amount increased by about 5% compared to Sample 2, but in the case of Sample 3, water droplets remained in the sand. In the case of Sample 1, the liquid passing amount remained at an increase rate of 2 to 4%, but it was shown that there was little water droplet residue.
