Description

本発明は、ペット採尿用敷設材及びこれを備えるペット用トイレ、並びにペット用トイレの使用方法に関する。 The present invention relates to a laying material for collecting pet urine, a pet toilet provided with the same, and a method of using the pet toilet.

ペットの健康管理として、ペットの尿を採取して該ペットの健康状態を検査する尿検査の重要性が増している。尿検査は、尿の比重等の物理的性状や、尿のpH値、ミネラルの含有量等の化学的組成を測定することによって、ペットの疾患の早期発見に寄与する。また尿検査は、物理的化学的検査に代えて、その色や濁り具合、尿量等を目視にて観察するだけでもペットの健康状態を把握する上で有効である。 As a pet health management, urinalysis, which collects pet urine and examines the health condition of the pet, is becoming more important. Urinalysis contributes to the early detection of pet diseases by measuring the physical properties such as the specific density of urine and the chemical composition such as the pH value of urine and the content of minerals. In addition, the urine test is effective in grasping the health condition of a pet simply by visually observing its color, turbidity, urine volume, etc., instead of the physical and chemical test.

本出願人は、膨潤や崩壊しないという耐水性に加え、消臭性能を高度なレベルで持続させることを目的として、所定の吸水率を有し、植物由来の素材の粉砕物を主構成基材としたペット用***物処理材を提案した(特許文献1)。 The applicant has a predetermined water absorption rate for the purpose of maintaining a high level of deodorant performance in addition to water resistance that does not swell or disintegrate, and the main constituent base material is a crushed product of a plant-derived material. We have proposed an excrement treatment material for pets (Patent Document 1).

また本出願人は、尿検体の採取を容易にすることを目的として、仕切層により上層部分と下層部分とに区画されたトイレ本体と、該下層部分に収容され、該上層部分で排尿された尿を採取するトレーとを備えるペット用トイレを提案した(特許文献2)。このペット用トイレは、仕切層の上層部分において便床を形成するために、上述した***物処理材を用いることができることも同文献に記載されている。 Further, for the purpose of facilitating the collection of urine samples, the applicant was accommodated in a toilet body divided into an upper layer portion and a lower layer portion by a partition layer and the lower layer portion, and urinated in the upper layer portion. We have proposed a litter box equipped with a tray for collecting urine (Patent Document 2). It is also described in the same document that the above-mentioned excrement treatment material can be used for forming a toilet bed in the upper portion of the partition layer in this pet toilet.

ところで、上述した***物処理材等の敷設材を備えるペット用トイレを尿検体の採取のために用いる場合、敷設材は、尿の採取部材であるトレーに尿を落下させやすい形状となっているとともに、尿のpHや構成成分に影響を与えない材質で構成されていることが望まれる。これに加えて、尿検体への異物の混入に起因する不都合、例えばペットの健康状態の誤判定を防止するために、微粉等の異物の発生が起こりにくい敷設材を用いることも望まれる。特許文献1及び2に記載の***物処理材は、尿のpHや成分に影響を与えない材質で構成されているが、尿検体の採取性の向上と、微粉等の異物混入の低減との両立に関して改善の余地があった。 By the way, when a pet toilet provided with a laying material such as the excrement treatment material described above is used for collecting a urine sample, the laying material has a shape that makes it easy for urine to fall on a tray that is a urine collecting member. At the same time, it is desirable that the material is made of a material that does not affect the pH or constituents of urine. In addition to this, in order to prevent inconvenience caused by contamination of the urine sample with foreign matter, for example, erroneous determination of the health condition of the pet, it is also desirable to use a laying material in which foreign matter such as fine powder is unlikely to be generated. The excrement treatment materials described in Patent Documents 1 and 2 are made of a material that does not affect the pH and components of urine, but improve the collectability of urine samples and reduce the contamination of foreign substances such as fine powder. There was room for improvement in terms of compatibility.

したがって、本発明の課題は、尿の物理的化学的性質に影響を与えることなく、尿の採取性を高めることができるペット採尿用敷設材及びこれを備えるペット用トイレ、並びにペット用トイレの使用方法を提供することにある。 Therefore, an object of the present invention is the use of a pet urine collection laying material capable of improving urine collection without affecting the physical and chemical properties of urine, a pet toilet provided with the same, and a pet toilet.

以下、本発明を、その好ましい実施形態に基づき図面を参照しながら説明する。本発明のペット採尿用敷設材(以下、これを単に「敷設材」ともいう。)は、例えば犬や猫、ウサギ、ハムスター等ペットから***された尿を採取する際に用いることができるものであり、特に、猫から***された尿を採取する際に用いる猫砂等の敷設材として有用なものである。 Hereinafter, the present invention will be described based on the preferred embodiment with reference to the drawings. The laying material for pet urine collection of the present invention (hereinafter, this is also simply referred to as "laying material") can be used for collecting urine excreted from pets such as dogs, cats, rabbits, and hamsters. In particular, it is useful as a laying material for cat sand and the like used when collecting urine excreted from cats.

本発明の敷設材は、その少なくとも外表面が合成樹脂から構成されていることが好ましい。少なくとも外表面が合成樹脂からなる態様としては、例えば、(i)外表面及び内部がともに合成樹脂から構成された中実の態様、(ii)合成樹脂からなる外表面を備えた中空の態様、又は(iii)外表面が合成樹脂からなり、且つ内部が合成樹脂以外の材料で構成された中空又は中実の態様等が挙げられる。これらのうち、敷設材の製造効率の向上並びに成形性及び保形性の向上の観点から、敷設材は、外表面及び内部がともに合成樹脂から構成された中実の態様によって、合成樹脂からなる外表面を少なくとも備えていることが好ましい。合成樹脂及び合成樹脂以外の材料の詳細は後述する。 It is preferable that at least the outer surface of the laying material of the present invention is made of synthetic resin. Examples of the embodiment in which at least the outer surface is made of synthetic resin include (i) a solid aspect in which both the outer surface and the inside are made of synthetic resin, and (ii) a hollow embodiment having an outer surface made of synthetic resin. Alternatively, (iii) a hollow or solid mode in which the outer surface is made of a synthetic resin and the inside is made of a material other than the synthetic resin can be mentioned. Of these, from the viewpoint of improving the manufacturing efficiency of the laying material and improving the moldability and shape retention, the laying material is made of synthetic resin in a solid manner in which both the outer surface and the inside are made of synthetic resin. It preferably has at least an outer surface. Details of the synthetic resin and materials other than the synthetic resin will be described later.

本発明の敷設材は、その少なくとも外表面が撥水性を有していることが好ましい。「撥水性を有する」とは、敷設材の外表面と水との接触角が90度以上のものであり、好ましくは100度以上、更に好ましくは110度以上である。敷設材にこのような接触角を発現させるためには、例えば、撥水性を有する合成樹脂を用いて敷設材の外表面を形成したり、該敷設材の表面に撥水処理をしたりする等の方法が挙げられる。 It is preferable that at least the outer surface of the laying material of the present invention has water repellency. “Has water repellency” means that the contact angle between the outer surface of the laying material and water is 90 degrees or more, preferably 100 degrees or more, and more preferably 110 degrees or more. In order to develop such a contact angle in the laying material, for example, the outer surface of the laying material is formed by using a synthetic resin having water repellency, or the surface of the laying material is treated with water repellency. Method can be mentioned.

敷設材の外表面と水との接触角は、例えば以下の方法で測定することができる。すなわち、接触角の被測定面である敷設材の外表面に、イオン交換水1μLの液滴を付着させ、該液滴を、液滴と敷設材との界面が見える側面から録画して、その録画した画像に基づき接触角を測定する。測定装置として例えば株式会社キーエンス製のマイクロスコープVHX−1000を用いる。録画された複数の画像のうち、液滴の輪郭が鮮明な画像を10枚選択し、その10枚の画像それぞれについて基準面に基づき液滴の接触角を計測し、それらの接触角の算術平均値を算出する。測定環境は、気温23±2℃、相対湿度50±5%RHとする。敷設材の表面が平面を有する形状である場合、接触角は、平面部分を被測定面として測定する。 The contact angle between the outer surface of the laying material and water can be measured by, for example, the following method. That is, a droplet of 1 μL of ion-exchanged water is attached to the outer surface of the laying material, which is the surface to be measured at the contact angle, and the droplet is recorded from the side where the interface between the droplet and the laying material can be seen. The contact angle is measured based on the recorded image. As a measuring device, for example, a microscope VHX-1000 manufactured by KEYENCE CORPORATION is used. From the plurality of recorded images, 10 images with a clear outline of the droplet are selected, the contact angle of the droplet is measured based on the reference plane for each of the 10 images, and the arithmetic mean of the contact angles is measured. Calculate the value. The measurement environment is an air temperature of 23 ± 2 ° C. and a relative humidity of 50 ± 5% RH. When the surface of the laying material has a flat surface, the contact angle is measured with the flat surface portion as the surface to be measured.

本発明の敷設材は、円柱様形状を有していることが好ましい。本明細書における「円柱様形状」とは、軸方向に直交する断面視形状が円である立体形状を指す。また本明細書における「円」は、真円のほか、短軸の長さに対する長軸の長さの比が2以下である楕円を包含する。 The laying material of the present invention preferably has a cylindrical shape. As used herein, the term "cylindrical shape" refers to a three-dimensional shape having a circular cross-sectional view shape orthogonal to the axial direction. Further, the “circle” in the present specification includes not only a perfect circle but also an ellipse in which the ratio of the length of the major axis to the length of the minor axis is 2 or less.

具体的には、敷設材1における円柱様形状は、(i)図1(a)に示すように、底面Aの平面視形状が円であり、各底面Aの面積が同一である真円柱状及び楕円柱状等の円柱状の形状、(ii)図1(b)に示すように、底面A及び天面Bの平面視形状がいずれも円であり、底面Aと天面Bとの面積が異なる円錐台状の形状、並びに、(iii)図1(c)に示すように、円錐台における天面Bの面積が実質的にゼロである円錐状の形状、等の各立体形状を包含する。これらの立体形状は、図1(a)ないし(c)に示すように、断面視形状の図心を結ぶ仮想線である軸Lが直線状に形成されていてもよく、あるいは、図1(d)に示すように、軸Lが曲線状となって湾曲している円柱状の形状であってもよい。上述した形状を有する敷設材は、単一の円柱様形状を有する敷設材の集合体として用いてもよく、又は二種以上の円柱様形状の敷設材を複数組み合わせた集合体として用いてもよい。 Specifically, as shown in FIG. 1A, the columnar shape of the laying material 1 is a true columnar shape in which the bottom surface A has a circular shape in a plan view and the area of each bottom surface A is the same. And a columnar shape such as an elliptical columnar shape, (ii) As shown in FIG. 1 (b), both the bottom surface A and the top surface B have a circular shape in a plan view, and the area of the bottom surface A and the top surface B is large. Includes different truncated cone shapes and, as shown in FIG. 1 (c), (iii) a truncated cone shape in which the area of the top surface B of the truncated cone is substantially zero, and the like. .. In these three-dimensional shapes, as shown in FIGS. 1 (a) to 1 (c), the axis L, which is a virtual line connecting the centroids of the cross-sectional view shape, may be formed in a straight line, or in FIG. 1 ( As shown in d), it may have a columnar shape in which the axis L is curved and curved. The laying material having the above-mentioned shape may be used as an aggregate of laying materials having a single columnar shape, or may be used as an aggregate of a plurality of laying materials having two or more kinds of cylindrical shapes. ..

また、上述した各円柱様形状を側面視したときに、その母線Sは、図2(a)ないし(d)に示すように直線であってもよく、あるいは、図2(e)に示すように曲線であってもよい。また、上述した各円柱様形状における底面A及び天面Bは、図2(a)、(b)及び(e)に示すように平面であってもよく、図2(c)及び(d)に示すように凹状又は凸状、あるいは凹凸状に形成された曲面であってもよい。このような形状を有する敷設材は、単一の円柱様形状を有する敷設材の集合体として用いてもよく、又は二種以上の円柱様形状の敷設材を複数組み合わせた集合体として用いてもよい。 Further, when each of the above-mentioned cylindrical shapes is viewed from the side, the generatrix S may be a straight line as shown in FIGS. 2 (a) to 2 (d), or as shown in FIG. 2 (e). May be a curve. Further, the bottom surface A and the top surface B in each of the above-mentioned cylindrical shapes may be flat as shown in FIGS. 2 (a), (b) and (e), and FIGS. 2 (c) and 2 (d) As shown in the above, the curved surface may be concave, convex, or uneven. The laying material having such a shape may be used as an aggregate of laying materials having a single columnar shape, or may be used as an aggregate of a plurality of laying materials having two or more kinds of cylindrical shapes. Good.

これらの円柱様形状のうち、製造時における成形性の簡便性と、使用時における取扱い性とを両立する観点から、軸が直線状の円柱状の形状又は軸が湾曲している円柱状の形状であることが好ましく、軸が直線状の円柱状形状であることがより好ましく、真円柱状の形状であることが更に好ましい。 Of these cylindrical shapes, from the viewpoint of achieving both ease of moldability during manufacturing and handleability during use, a cylindrical shape with a linear shaft or a cylindrical shape with a curved shaft. It is more preferable that the shaft has a linear columnar shape, and it is further preferable that the shaft has a true columnar shape.

図2(a)ないし(e)に示すように、敷設材1は、軸方向の長さH1が最大径部分の直径D1以上である寸法を有していることが好ましい。詳細には、最大径部分の直径D1に対する軸方向の長さH1の比(H1/D1)が1.0以上であり、好ましくは1.1以上、より好ましくは1.5以上、更に好ましくは2以上であり、好ましくは5以下、より好ましくは4以下、更に好ましくは3.5以下である。円柱様形状にいて、最大径部分の断面視形状が真円状以外の形状である場合には、その直径は最大差し渡し長さとする。また、図2(c)及び(d)に示すように、円柱様形状において天面及び底面の少なくとも一方が曲面で形成されている場合、軸方向の長さH1は、軸方向に沿う方向における最大差し渡し長さとする。 As shown in FIGS. 2A to 2E, the laying material 1 preferably has a dimension in which the axial length H1 is equal to or larger than the diameter D1 of the maximum diameter portion. Specifically, the ratio of the axial length H1 to the diameter D1 of the maximum diameter portion (H1 / D1) is 1.0 or more, preferably 1.1 or more, more preferably 1.5 or more, still more preferably. It is 2 or more, preferably 5 or less, more preferably 4 or less, and further preferably 3.5 or less. If the shape is cylindrical and the cross-sectional view of the maximum diameter portion is a shape other than a perfect circle, the diameter shall be the maximum transfer length. Further, as shown in FIGS. 2C and 2D, when at least one of the top surface and the bottom surface is formed by a curved surface in a cylindrical shape, the axial length H1 is in the direction along the axial direction. The maximum delivery length.

敷設材の使用時において、敷設材間の隙間を大きくして、敷設材間で尿が保持されないように形成しやすくする観点から、敷設材の軸方向の長さH1は、好ましくは10mm以上、更に好ましくは20mm以上であり、好ましくは40mm以下、更に好ましくは30mm以下である。
また、敷設材の使用時において、敷設材間の隙間を大きくして、敷設材間で尿が保持されないように形成する観点から、敷設材の最大径部分の直径D1は、好ましくは4mm以上、更に好ましくは5mm以上であり、好ましくは10mm以下、更に好ましくは8mm以下である。
When the laying material is used, the axial length H1 of the laying material is preferably 10 mm or more from the viewpoint of increasing the gap between the laying materials and facilitating the formation of urine so as not to be retained between the laying materials. It is more preferably 20 mm or more, preferably 40 mm or less, still more preferably 30 mm or less.
Further, when the laying material is used, the diameter D1 of the maximum diameter portion of the laying material is preferably 4 mm or more from the viewpoint of increasing the gap between the laying materials so that urine is not retained between the laying materials. It is more preferably 5 mm or more, preferably 10 mm or less, still more preferably 8 mm or less.

以上の構成を有する敷設材によれば、その少なくとも外表面が合成樹脂からなり、且つ撥水性を有しているので、敷設材と尿とが接触した場合に、敷設材の構成成分の尿への溶解等に起因して尿比重等の物理的性質が変化したり、敷設材の構成成分と尿との化学反応に起因して、尿のpHやミネラル分等の化学的組成の変化が生じにくい。その結果、採取対象となる尿の物理的化学的性質に影響を与えずに、ペットの健康状態が反映された尿の採取が可能となる。
これに加えて、敷設材は、少なくとも外表面が撥水性を有しているとともに、所定の寸法を有する円柱様形状となっているので、該敷設材の集合体を例えばペット用トイレの猫砂として用いたときに、ペットの排尿部位である集合体表面に凹凸が形成されやすくなり、尿が敷設材上に溜まりにくくなる。これとともに、敷設材間の間隙が形成されやすくなるので、敷設材どうしの間に尿が保持されにくくなり、敷設材どうしの間を更に容易に通過しやすくなる。その結果、尿の採取性を高めることができる。更に、敷設材の表面に尿が付着残存しづらくなるので、尿由来の悪臭の発生を低減することができるという利点もある。
一方、角柱状形状などの平面が多い立体形状を有する敷設材を集合体として用いた場合、その集合体表面は平面となりやすく、敷設材上に尿が溜まりやすい。これに加えて、敷設材どうしの接触面積が大きくなってしまうことに起因して、敷設材間に尿が保持されやすく、検体の採取量が十分なものとならなかったり、敷設材間に残存した尿からの悪臭発生の原因の一つとなり得る。また、球状の立体形状を有する敷設材を集合体として用いた場合、ペットの動き等に起因して、適正な使用場所以外の場所に敷設材が飛散しやすく、清掃や補充等の手間が増大し得る。
According to the laying material having the above structure, at least the outer surface thereof is made of synthetic resin and has water repellency. Therefore, when the laying material comes into contact with urine, it becomes urine, which is a component of the laying material. Changes in physical properties such as specific gravity of urine due to dissolution of urine, and changes in chemical composition such as pH and minerals of urine due to the chemical reaction between the constituents of the laying material and urine. Hateful. As a result, it is possible to collect urine that reflects the health condition of the pet without affecting the physical and chemical properties of the urine to be collected.
In addition to this, since the laying material has a water-repellent outer surface at least and has a cylindrical shape having a predetermined size, the aggregate of the laying material is, for example, cat sand of a pet toilet. When used as a pet, unevenness is likely to be formed on the surface of the aggregate, which is the urination site of the pet, and urine is less likely to collect on the laying material. At the same time, a gap is easily formed between the laying materials, so that urine is less likely to be held between the laying materials, and it becomes easier to pass between the laying materials. As a result, the collectability of urine can be improved. Further, since urine is less likely to adhere and remain on the surface of the laying material, there is an advantage that the generation of malodor derived from urine can be reduced.
On the other hand, when a laying material having a three-dimensional shape with many flat surfaces such as a prismatic shape is used as an aggregate, the surface of the aggregate tends to be flat and urine tends to collect on the laying material. In addition to this, due to the large contact area between the laying materials, urine is likely to be retained between the laying materials, and the amount of sample collected is not sufficient or remains between the laying materials. It can be one of the causes of foul odors from urine. In addition, when a laying material having a spherical three-dimensional shape is used as an aggregate, the laying material is likely to scatter to a place other than the proper place of use due to the movement of the pet, etc., which increases the labor for cleaning and replenishment. Can be done.

本発明に用いられる合成樹脂としては、例えば、ジアセチルセルロース等の電離可能な官能基を側鎖に有する樹脂、ポリ酢酸ビニル及びアクリル樹脂等のエステル結合を側鎖に有する樹脂、ポリエチレン、ポリプロピレン及びポリイソブチレン等の脂肪族基を側鎖に有する樹脂、ポリ塩化ビニル及びポリテトラフルオロエチレン等のハロゲンを側鎖に有する樹脂、並びに、ポリスチレン等の芳香族基を側鎖に有する樹脂等の熱可塑性樹脂が挙げられる。これらは単独で用いてもよく、二種以上を組み合わせて用いてもよい。合成樹脂を二種以上を組み合わせて用いる場合には、各合成樹脂が均一に又は不均一に混合されて境界が不明瞭な態様となっていてもよく、各合成樹脂が層状等に構成されて境界が明瞭な態様となっていてもよい。 Examples of the synthetic resin used in the present invention include a resin having an ionizable functional group in the side chain such as diacetyl cellulose, a resin having an ester bond in the side chain such as polyvinyl acetate and an acrylic resin, polyethylene, polypropylene and poly. Thermoplastic resins such as resins having an aliphatic group such as isobutylene in the side chain, resins having halogen such as polyvinyl chloride and polytetrafluoroethylene in the side chain, and resins having aromatic groups such as polystyrene in the side chain. Can be mentioned. These may be used alone or in combination of two or more. When two or more kinds of synthetic resins are used in combination, each synthetic resin may be mixed uniformly or non-uniformly to have an unclear boundary, and each synthetic resin is configured in a layered manner or the like. The boundary may be in a clear manner.

これらの合成樹脂のうち、脂肪族基を側鎖に有する樹脂、ハロゲンを側鎖に有する樹脂及び芳香族基を側鎖に有する樹脂のうち少なくとも一種を用いることが好ましく、ポリエチレン及びポリプロピレンのうち少なくとも一種の樹脂を用いることがより好ましい。特に、これらの合成樹脂は、樹脂自体の物性として、水との接触角が大きく撥水性を有しているので、撥水処理を別途施さなくても撥水性を有する外表面を効率よく形成できる点で有利である。 Among these synthetic resins, it is preferable to use at least one of a resin having an aliphatic group in the side chain, a resin having a halogen in the side chain, and a resin having an aromatic group in the side chain, and at least one of polyethylene and polypropylene. It is more preferable to use a kind of resin. In particular, since these synthetic resins have a large contact angle with water and have water repellency as the physical characteristics of the resin itself, an outer surface having water repellency can be efficiently formed without separately performing a water repellent treatment. It is advantageous in that.

敷設材における合成樹脂の含有量は、好ましくは50質量%以上、より好ましくは80質量%以上、更に好ましくは90質量%以上であり、一層好ましくは100質量%、すなわち実質的に合成樹脂で構成された敷設材であることが好ましい。合成樹脂の含有量をこのような範囲とすることによって、尿の採取性の向上に加えて、使用後の敷設材を洗浄して再利用することができ、廃棄物量を低減することができるので、コスト低減等の経済性向上に有用な敷設材となる。また、保形性が高いので、敷設材の崩壊や、尿との接触による膨潤等が生じず、採取対象となる尿への敷設材由来の異物混入が生じないものとなる。 The content of the synthetic resin in the laying material is preferably 50% by mass or more, more preferably 80% by mass or more, still more preferably 90% by mass or more, still more preferably 100% by mass, that is, substantially composed of synthetic resin. It is preferable that the laying material is used. By setting the content of the synthetic resin in such a range, in addition to improving the collectability of urine, the laying material after use can be washed and reused, and the amount of waste can be reduced. It is a useful laying material for improving economic efficiency such as cost reduction. Further, since the shape-retaining property is high, the laying material does not collapse or swell due to contact with urine, and foreign matter derived from the laying material does not enter the urine to be collected.

敷設材は、これを集合体としたときの空隙率が、好ましくは20%以上、より好ましくは30%以上、更に好ましくは40%以上であり、好ましくは80%以下、より好ましくは60%以下、更に好ましくは50%以下である。空隙率がこのような割合となっていることによって、敷設材間の間隙が大きく形成され、敷設材どうしの間に尿が更に保持されにくくなり、敷設材どうしの間をより効果的に通過しやすくなる。その結果、尿の採取性をより一層高めることができる。 The porosity of the laying material when it is assembled is preferably 20% or more, more preferably 30% or more, further preferably 40% or more, preferably 80% or less, more preferably 60% or less. , More preferably 50% or less. With such a porosity, a large gap is formed between the laying materials, making it more difficult for urine to be retained between the laying materials, and more effectively passing between the laying materials. It will be easier. As a result, the collectability of urine can be further improved.

敷設材の集合体における空隙率は、以下の方法で測定することができる。まず、メスシリンダー等の目盛り付きの容器に、敷設材の集合体を所定体積分投入する。次いで、投入した敷設材の体積と同一の体積の水性液を容器内に投入して、水性液の液面に敷設材が浮かないように、敷設材の集合体を浸漬させる。このとき、水性液の体積V2(mL)を容器の目盛りを読み取って測定し、投入前の水性液の体積V1(mL)に対する、体積V2と体積V1との差((V2-V1)/V1)の百分率(%)を本発明の空隙率として算出する。本測定に用いる水性液は、測定対象の敷設材が水性液の液面に敷設材が浮かないような比重を有する組成であることが好ましく、例えば水単独やアルコール単独としたり、あるいは、水、エタノール及びグリセリン等のアルコール類、界面活性剤、並びに塩の一種又は二種以上を混合して比重を調整したものを用いることができる。また水性液の比重を調整することに加えて、又はこれに代えて、網等の部材を用いて敷設材を水性液中に浸漬させるとともに、該部材の体積を除外して空隙率を算出してもよい。詳細な測定方法は、後述する実施例にて詳述する。 The porosity of the laying material aggregate can be measured by the following method. First, an aggregate of laying materials is put into a container with a scale such as a graduated cylinder in a predetermined volume. Next, an aqueous liquid having the same volume as the volume of the charged laying material is charged into the container, and the aggregate of the laying material is immersed so that the laying material does not float on the liquid surface of the aqueous liquid. At this time, the volume V2 (mL) of the aqueous liquid is measured by reading the scale of the container, and the difference between the volume V2 and the volume V1 ((V2-V1) / V1) with respect to the volume V1 (mL) of the aqueous liquid before charging. ) Is calculated as the porosity of the present invention. The aqueous liquid used in this measurement preferably has a composition in which the laying material to be measured has a specific density so that the laying material does not float on the liquid surface of the aqueous liquid. Alcohols such as ethanol and glycerin, surfactants, and one or more salts may be mixed to adjust the specific gravity. In addition to or instead of adjusting the specific gravity of the aqueous liquid, the laying material is immersed in the aqueous liquid using a member such as a net, and the porosity is calculated by excluding the volume of the member. You may. The detailed measurement method will be described in detail in Examples described later.

敷設材において用いられ得る合成樹脂以外の材料としては、例えば、木粉(木質又は樹皮の粉砕物)や、竹粉砕物、種子油残査、穀物外皮粉砕物、草本粉砕物等の植物由来粉砕物、ガラス及びシリカ等のケイ酸化合物、活性炭及びゼオライト等の無機多孔性物質、砂利等の鉱物等が挙げられる。合成樹脂以外の材料の含有量は、好ましくは50質量%以下、より好ましくは30質量%以下であり、更に好ましくは実質的に非含有である。 Materials other than synthetic resins that can be used in laying materials include, for example, wood flour (crushed wood or bark), crushed bamboo, residual seed oil, crushed grain hulls, crushed herbaceous plants, and other plant-derived crushed materials. Examples thereof include silicic acid compounds such as glass and silica, inorganic porous substances such as activated carbon and zeolite, and minerals such as gravel. The content of the material other than the synthetic resin is preferably 50% by mass or less, more preferably 30% by mass or less, and further preferably substantially non-containing.

敷設材の外表面に撥水処理を行う場合、その方法としては、例えば、シリコーン系ポリマーを塗工して被覆したり、あるいは、撥水性を有する上述の合成樹脂を塗工して外表面を被覆したりする方法等が挙げられる。 When water-repellent treatment is applied to the outer surface of the laying material, for example, a silicone-based polymer is applied to cover the outer surface, or the above-mentioned synthetic resin having water repellency is applied to the outer surface. Examples include a method of covering.

You may use it. In this case, even when the pet urinates at an arbitrary position on the laying material aggregate, the gap between the laying materials is uniformly secured to improve the passage of urine and reduce the retention of urine between the laying materials. From the viewpoint of achieving both of these, it is preferable to use a laying material having at least one of a cylindrical shape and a truncated cone shape as an aggregate, and the columnar shape or the truncated cone shape is preferable. It is more preferable to use the laying material having a shape as an aggregate, and it is further preferable to use only the laying material having a columnar shape as an aggregate.

〔敷設体集合体の空隙率の測定〕
各実施例の敷設材の集合体における空隙率は、以下の方法で測定した。
まず、容量500mLのガラス製メスシリンダー内に、測定対象となる敷設材の集合体を200mLの目盛りまで敷き詰めた。次いで、以下に示す組成の水性液200mL(体積V1)をメスシリンダー内に投入し、敷設材を浸漬させた。この状態で、メスシリンダー内の水性液の体積V2(mL)をメスシリンダーの目盛りを読み取って測定した。敷設材の集合体における空隙率(%)は、以下の式(A)から算出した。
空隙率(%)=100×(体積V2‐体積V1)/(体積V1) ・・・(A)
[Measurement of porosity of laying aggregates]
The porosity of the assembly of the laying materials of each example was measured by the following method.
First, an aggregate of laying materials to be measured was spread up to a scale of 200 mL in a glass graduated cylinder having a capacity of 500 mL. Next, 200 mL (volume V1) of an aqueous liquid having the composition shown below was put into a graduated cylinder, and the laying material was immersed. In this state, the volume V2 (mL) of the aqueous liquid in the graduated cylinder was measured by reading the scale of the graduated cylinder. The porosity (%) in the aggregate of the laying material was calculated from the following formula (A).
Porosity (%) = 100 x (volume V2-volume V1) / (volume V1) ... (A)

<水性液の組成>
・無水エタノール:67.9質量%
・水:31.79質量%
・グリセリン脂肪酸エステル:0.2質量%
・グリセリン:0.1質量%
・乳酸ナトリウム:0.01質量%
<Composition of aqueous liquid>
-Anhydrous ethanol: 67.9% by mass
-Water: 31.79% by mass
-Glycerin fatty acid ester: 0.2% by mass
・ Glycerin: 0.1% by mass
・ Sodium lactate: 0.01% by mass

〔残液量の評価〕
実施例の敷設材を用いて、敷設材上の残液量を評価した。まず、目開き2.0mmの金属網上に、敷設材の集合体を約2cmの厚さとなるように敷設した。その後、擬似尿として、15gの生理食塩水を敷設材上に滴下し、敷設材及び金属網を通過して落下した生理食塩水の質量(g)を測定した。残液量は、滴下前の生理食塩水の質量(15g)から、落下した生理食塩水の質量(g)を差し引いて求めた。残液量が少ないほど、尿が敷設材間で溜まりにくくなり、尿の採取性が高いものであることを示す。結果を図6(b)に示す。
[Evaluation of residual liquid amount]
The amount of residual liquid on the laying material was evaluated using the laying material of the example. First, an aggregate of laying materials was laid on a metal net having a mesh size of 2.0 mm so as to have a thickness of about 2 cm. Then, as simulated urine, 15 g of physiological saline was dropped onto the laying material, and the mass (g) of the physiological saline dropped through the laying material and the metal net was measured. The amount of residual liquid was determined by subtracting the mass (g) of the dropped physiological saline solution from the mass (15 g) of the physiological saline solution before dropping. The smaller the amount of residual liquid, the less likely it is that urine will collect between the laying materials, indicating that the urine collection property is high. The results are shown in FIG. 6 (b).

図6(b)に示すように、各実施例の敷設材は、残液量が少ないものであった。したがって、本発明の敷設材は、尿の採取性が高いものである。これとともに、尿の成分や物性に影響を与えない材質である合成樹脂からなり、撥水性が高いので、尿の物理的化学的性質に影響を与えないものであることが判る。特に、最大径部分の直径D1に対する軸方向の長さH1の比を好適な範囲とした実施例2の敷設材は、残液量が更に少なくなっており、尿の採取性を一層高めることができる。 As shown in FIG. 6B, the laying material of each example had a small amount of residual liquid. Therefore, the laying material of the present invention has high urine collection property. At the same time, it is made of synthetic resin which is a material that does not affect the components and physical properties of urine, and has high water repellency, so that it can be seen that it does not affect the physical and chemical properties of urine. In particular, the laying material of Example 2 in which the ratio of the axial length H1 to the diameter D1 of the maximum diameter portion is in a suitable range has a further reduced amount of residual liquid, and can further improve the collectability of urine. it can.
