Processed into a corrugated honeycomb structure. The average area of the hole openings is 16 mm 2 / piece. This was cut into 5 cm ⁇ 12 cm.
- Urethane (Examples 2 to 4): 3 mm, 7 mm, and 10 mm urethane foams were cut into 5 cm ⁇ 12 cm, respectively.
- Nonwoven (Comparative Examples 1-3): each cut 35 g / m 2 basis weight, 70 g / m 2 basis weight, a 100 g / m 2 basis weight of the nonwoven fabric in 5 cm ⁇ 12cm.
- Compressive strength test 1 (1) The sample is fixed, and from the lateral direction (perpendicular to the thickness direction) of the sample to the side surface of the sample with a circular plunger having a tip of 10 mm in diameter, until the sample is deformed 1 cm, 500 mm A load was applied at a rate of / min. About Example 1, it measured by applying a load to both the X direction (lamination direction) from the side of 12 cm shown in FIG. 5 and the Y direction (non-lamination direction) from the side of 5 cm. For the example, a load was applied to the side of the sample 5 cm long. (2) The peak load was measured with a digital force gauge. For each sample, the load was measured four times, and the average value (N) is shown in Table 1.
- a compressive strength of approximately 0.35 N or higher, preferably 1 N or higher, is a preferable compressive strength with respect to the pressure in the lateral direction caused by the stepping of a 3 kg small dog.
- the paper liquid permeable panel of Example 1 has sufficient compressive strength in both the laminating direction and the non-laminating direction.
- urethane foam has favorable compressive strength when it has a thickness of 10 mm or more.
- the non-woven fabrics of Comparative Examples 1 to 3 are often used as materials for pet sheets, but it can be seen that they do not have any compressive strength against pressure from the lateral direction.
- the paper liquid permeable panel having a corrugated honeycomb structure of Example 1 has stronger compressive strength in the stacking direction.
- this liquid permeable panel is used in an animal system toilet, for example, an entrance of a dog with a low wall is provided in a part of the upper container side wall portion 42, the direction of entrance of the dog is specified, and compression by stepping on the dog It can be seen that by making the direction in which the force is applied coincide with the direction in which the corrugated honeycomb structure of the liquid permeable panel 3 is laminated, it is possible to prevent kinking against a higher compressive force.
- Example 5 Example 6, and Comparative Example 4 described later, artificial urine having the following composition was used.
- Artificial urine composition 400 g of urea Sodium chloride 160g Magnesium sulfate (7 hydrate) 16g Calcium chloride (dihydrate) 6g Adjust the above with water to a total of 20L. Add 2g of Blue No. 1 to the adjustment solution and color it.
- Example 5 ⁇ Example 5, Example 6, and Comparative Example 4>
- a liquid permeability test and a foot wettability test for ease of foot wetting Test for evaluation.
- the results of the liquid permeability test are shown in Table 3, and the results of the foot wettability test are shown in Table 4, respectively.
- Paper-made liquid permeable panel (Example 5): A neurite coat used as a base paper, A flute corrugated cardboard processed into a corrugated honeycomb structure (basis weight 130 g / m 2 ), average area of hole openings 16 mm 2 / piece .
- Non-woven liquid permeable panel (Example 6): Deodorized paper using polyester fiber containing activated carbon is used as base paper, A flute corrugated cardboard processed into corrugated honeycomb structure (basis weight 210 g / m 2 ), hole opening Part average area 10.5 mm 2 / piece, paraffinic water repellent 4.8% added.
- Plastic slats (Comparative Example 4): Mesh tray (made of polypropylene, opening shape: length 6 mm x width 6 mm, width in the horizontal direction 3.5 mm, thickness in the vertical direction 3.5 mm)
- Liquid permeability test A pan whose weight (A) has been measured in advance is placed under the sample whose liquid permeability is to be measured. About 30 ml of artificial urine is measured and the weight (B) of the artificial urine is measured. A cylinder with an inner diameter of 60 mm is placed on the sample, and artificial urine is dripped evenly inside the cylinder. When the artificial urine droplet no longer falls from the sample, the weight (C) of the tray containing the artificial urine is measured. The value of liquid permeability is calculated based on the following formula.
- Liquid permeability (%) (weight (C) ⁇ weight (A)) ⁇ weight (B) ⁇ 100
- Foot wettability (g) weight (B) -weight (A)
- Example 5 and Example 6 using the liquid permeable panel 3 made of a corrugated honeycomb-shaped panel made of paper or nonwoven fabric it was found that the liquid permeable panel 3 showed excellent liquid permeability. For this reason, when the liquid permeable panel 3 of Example 5 and Example 6 is used, most of the artificial urine passes through the liquid permeable panel 3, and the artificial urine slightly remaining on the liquid permeable panel 3 is liquid permeable panel 3. As shown in Table 5 in the foot wettability test, it was found that almost no artificial urine adhered to the filter paper.
- the paper-made liquid permeable panel having a corrugated honeycomb-shaped structure is suitable as a liquid permeable panel that covers the excreta absorbing part of the animal system toilet because of its high liquid permeability and high compressive strength. It turns out that.

Abstract
Description
[側面1cm圧縮変形荷重:液透過パネルの厚さ方向に対して垂直な側面方向から、先端が直径10mmの円系プランジャーで、500mm/minの速度で圧縮荷重をかけた際に、液透過パネルが1cm変形するまでの荷重。]
まず、本発明の実施形態である動物用システムトイレ1を用いて、動物用システムトイレ1の全体構造について説明する。
次に、使い捨ての液透過パネル3について説明する。液透過パネル3は全体として平面パネル状である。図1及び図2に示されるように、液透過パネル3は排泄容器2の開口部の略全面を覆うように上部容器4に対して着脱可能に構成される。より具体的には、液透過パネル3は、図5に示すように、複数のシート部材(後述の波板状シート32及び平板状シート33)が厚さ方向に沿うように配置されると共に隣り合うシート部材が所定箇所で接合されて形成されている。つまり、液透過パネル3は、シート部材により連続的に形成される壁部と、この壁部により囲まれた空間により形成され厚さ方向に貫通する複数の孔部31と、を備える開孔パネルである。
液透過パネル3の側面1cm圧縮変形荷重(以下単に圧縮強度ともいう)については、後述する実施例における圧縮強度試験1記載の方法で、測定した場合の圧縮強度が0.35N以上20N以下であり、5N以上15N以下が好ましい。かかる圧縮強度を有する使い捨て液透過パネル3を用いることにより、動物用システムトイレにおいて、シートのよれやめくれによる尿漏れを防止することが可能となる。また、同時に孔部の潰れも防止できる。
液透過パネル3の液透過率は90%以上が好ましく、93%以上がより好ましい。かかる液透過率の使い捨て液透過パネル3を用いることにより、排泄後の液透過パネル3への尿の付着を低減でき、内部での尿の拡散や、踏みつけによる動物の足が濡れることを抑制しやすい。液透過パネル3の液透過率は下記の方法により測定出来る。
あらかじめ重量(A)を測定された受け皿を、液透過パネル3等の液透過率を測定する試料の下部に置く。人工尿約30mlを測りとり人工尿の重量(B)を測定する。試料上に内径60mmの円筒を置き、円筒の内側に人工尿をまんべんなく滴下する。試料から人工尿の液滴が落下しなくなった時点で人工尿の入った受け皿の重量(C)を測定する。液透過率の値を下式に基づいて算出する。なお、人工尿は後述する実施例の組成のものを使用する。
液透過率(%)=(重量(C)-重量(A))÷重量(B)×100
以下に記す方法に従い、下記の通り、紙製液透過パネル材料、ウレタン、不織布について、圧縮強度試験として、下記の試験1、2を行った。試験の結果を表1、表2に記す。
ウレタン(実施例2~4):それぞれ、厚さ3mm、7mm、10mmのウレタンフォームを5cm×12cmにカットした。
不織布(比較例1~3):それぞれ、35g/m2目付、70g/m2目付、100g/m2目付の不織布を5cm×12cmにカットした。
(1)試料を固定し、試料の横方向(厚さ方向に対して垂直な方向)から、試料の側面に対し、先端が直径10mmの円系プランジャーで、試料が1cm変形するまで、500mm/minの速度で荷重をかけた。実施例1については、図5に示す12cmの側面からのX方向(積層方向)と5cmの側面からのY方向(非積層方向)の両方向に荷重をかけて測定し、その他の実施例、比較例については、試料の長さ5cmの側辺に荷重をかけた。
(2)デジタルフォースゲージでピークの荷重を測定した。それぞれの試料について、各4回荷重を測定し、その平均値(N)を表1に記した。
(1)試料をトイレ表面に設置し、重量約3kgの小型犬で実際使用した。
(2)1日間使用し、よれやめくれが全くなかったものの結果を○、一回1cm以上のよれやめくれがあったものを△、2回以上1cm以上のよれやめくれがあったものを×とし、結果を表2に記した。
〔人工尿組成〕
尿素 400g
塩化ナトリウム 160g
硫酸マグネシウム(7水和物) 16g
塩化カルシウム(2水和物) 6g
以上を合計20Lになるように水で調整する。
調整液に、青色1号を2g加え着色する。
以下に記す方法に従い、下記の紙製液透過パネル材料、不織布性液透過パネル材料、及びプラスチック製スノコについて、それぞれ、5回ずつ、液透過率試験、足濡れ性試験(足の濡れやすさを評価するための試験)を行った。液透過率試験の結果を表3に、足濡れ性試験の結果を表4にそれぞれ記す。
紙製液透過パネル(実施例5):ニューレンコートを原紙として使用、Aフルート段ボールをコルゲートハニカム構造に加工したもの(坪量130g/m2)、孔部開口部の平均面積16mm2/個。
不織布性液透過パネル(実施例6):活性炭を含有したポリエステル繊維を使用した脱臭紙を原紙として使用、Aフルート段ボールをコルゲートハニカム構造に加工したもの(坪量210g/m2)、孔部開口部の平均面積10.5mm2/個、パラフィン系撥水剤4.8%添加。
プラスチック製スノコ(比較例4):メッシュトレイ(ポリプロピレン製、開口部形状:縦6mm×横6mm、横方向桟太さ3.5mm、縦方向桟太さ3.5mm)
あらかじめ重量(A)を測定された受け皿を、液透過率を測定する試料の下部に置く。人工尿約30mlを測りとり人工尿の重量(B)を測定する。試料上に内径60mmの円筒を置き、円筒の内側に人工尿をまんべんなく滴下する。試料から人工尿の液滴が落下しなくなった時点で人工尿の入った受け皿の重量(C)を測定する。液透過率の値を下式に基づいて算出する。
液透過率(%)=(重量(C)-重量(A))÷重量(B)×100
使い捨て液透過パネル3の材料の上に内径60mmの円筒を置き、その内側に30mlの人工尿をまんべんなく滴下する。人工尿の滴下後、円筒を取り除き、30分間放置する。10cm×10cmのろ紙(JIS P3801に定められる2種)の重量(A)を測定する。30分後、液透過パネル3の材料の人工尿を滴下した箇所の上に10cm×10cmのろ紙を載せ、5秒間静置する。5秒後、ろ紙を取り外し、ろ紙の重量(B)を測定する。足濡れ性の試験結果を下式に基づいて算出する。
足濡れ性(g)=重量(B)-重量(A)
