特許文献１のペット用おむつは、犬に対しても装着でき、猫に対しても装着できるように構成されている。出願人が鋭意調査した結果、猫と犬で普段の身体の動かし方が大きく異なることがわかった。より詳細には、犬は、地面を走る等、平面方向の動きが多く、猫は、犬と比較して、ジャンプしたり飛び降りたりする等の垂直方向の動きが多いことがわかった。垂直方向に身体を動かそうとすると、後足を曲げた状態から一気に伸ばしたり、脚の曲げ伸ばしとともに腹を凹ませた状態及び背中を丸めた状態から延ばしたりして、腹部、臀部及び足回りの皮膚の伸び縮み量が大きくなり易い。そのため、猫がおむつを着用した状態で時間が経過すると、おむつがずれたり外れたりする不具合があった。 The pet diaper of Patent Document 1 is configured so that it can be worn on dogs and also on cats. As a result of diligent investigation by the applicant, it was found that the way cats and dogs usually move their bodies differs greatly. More specifically, it was found that dogs have more movements in the plane direction such as running on the ground, and cats have more movements in the vertical direction such as jumping and jumping than dogs. When trying to move the body in the vertical direction, the abdomen, buttocks and undercarriage may be extended from the bent hind legs at a stretch, or from the bent and extended legs and the dented abdomen and the rounded back. The amount of expansion and contraction of the skin tends to increase. Therefore, there is a problem that the diaper shifts or comes off after a lapse of time while the cat is wearing the diaper.

本発明は、上記問題に鑑みてなされたものであり、着用時のずれを抑制できる猫用おむつを提供することを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a cat diaper capable of suppressing slippage when worn.

一態様に係る猫用おむつは、猫の胴回り方向に沿って配置される横方向と、前記横方向と直交し、猫の腹側から背側を繋ぐ方向に延びる縦方向と、吸収コアを有し、腹側域、股下域及び背側域に跨る本体部と、前記本体部よりも前記横方向の両外側に延出し、前記腹側域と前記背側域を接合するファスニングテープと、を有する。前記吸収コアは、前記横方向の内側に括れる括れ部を有する。前記括れ部の前記横方向の内側縁における前記腹側の端縁は、前記吸収コアの前記縦方向の中心よりも背側に位置している。 The cat diaper according to one embodiment has a lateral direction arranged along the waist direction of the cat, a vertical direction orthogonal to the lateral direction and extending in a direction connecting the ventral side to the dorsal side of the cat, and an absorption core. A main body that straddles the ventral, inseam, and dorsal regions, and a fastening tape that extends laterally from the main body and joins the ventral and dorsal regions. Have. The absorption core has a constriction that is constricted inward in the lateral direction. The ventral edge of the lateral medial edge of the constriction is located dorsal of the longitudinal center of the absorption core.

（１）実施形態の概要
本明細書及び添付図面の記載により、少なくとも以下の事項が明らかとなる。
一態様に係る猫用おむつは、猫の胴回り方向に沿って配置される横方向と、前記横方向と直交し、猫の腹側から背側を繋ぐ方向に延びる縦方向と、吸収コアを有し、腹側域、股下域及び背側域に跨る本体部と、前記本体部よりも前記横方向の両外側に延出し、前記腹側域と前記背側域を接合するファスニングテープと、を有する。前記吸収コアは、前記横方向の内側に括れる括れ部を有する。前記括れ部の前記横方向の内側縁における前記腹側の端縁は、前記吸収コアの前記縦方向の中心よりも背側に位置している。出願人が猫の着用状態を観察した結果、脚幅が最も狭くなる位置よりも腹側に延出する吸収コアの縦方向の長さは、腹側の端縁よりも腹側に延びる吸収コアの縦方向の長さに相当することがわかった。脚幅が最も狭くなる位置よりも腹側に延出する吸収コアの縦方向の長さを十分に確保できるため、垂直方向の動きによって脚を繰り返し前後に動かした場合であっても吸収コアによって身体を覆うことができる。また、脚幅が最も狭くなる位置よりも腹側に延出する吸収コアの縦方向の長さを十分に確保できるため、腹部の皮膚の伸び縮み量が大きくなった場合であっても吸収コアを追従させ続けることができ、おむつが着用された状態を維持し易い。 (1) Outline of Embodiment At least the following matters will be clarified by the description of this specification and the accompanying drawings.
The cat diaper according to one embodiment has a lateral direction arranged along the waist direction of the cat, a vertical direction orthogonal to the lateral direction and extending from the ventral side to the dorsal side of the cat, and an absorption core. A main body that straddles the ventral, inseam, and dorsal regions, and a fastening tape that extends laterally from the main body and joins the ventral and dorsal regions. Have. The absorption core has a constriction that is constricted inward in the lateral direction. The ventral edge of the lateral medial edge of the constriction is located dorsal of the longitudinal center of the absorption core. As a result of the applicant's observation of the wearing condition of the cat, the vertical length of the absorption core extending ventral to the position where the leg width is the narrowest is the absorption core extending ventral to the ventral edge. It was found to correspond to the vertical length of. Since the vertical length of the absorption core that extends ventral to the position where the leg width is the narrowest can be secured sufficiently, the absorption core allows the leg to be repeatedly moved back and forth by vertical movement. Can cover the body. In addition, since the length of the absorption core extending ventral to the ventral side from the position where the leg width is the narrowest can be sufficiently secured, the absorption core can be expanded even when the amount of expansion and contraction of the abdominal skin becomes large. It is easy to keep the diaper on.

好ましい一態様によれば、前記括れ部は、腹側に位置する腹基端縁、背側に位置する背基端縁、及び前記内側縁を繋ぐ側縁を有しており、前記括れ部の横方向の中心を通り、かつ前記縦方向に延びる仮想線が、前記腹基端縁から前記内側縁に延びる腹側縁と交差する第１交差点と、前記仮想線が、前記背基端縁から前記内側縁に延びる背側縁と交差する第２交差点と、の距離は、前記吸収コアの前記縦方向の長さに対する４０％未満であってよい。猫が垂直方向に動くと、着地等の衝撃や皮膚の縦方向の伸び縮みに起因しておむつが縦方向にずれ易くなる。このとき、後脚回りの縦方向のずれ量が吸収コアの４０％以下に抑え易い。たとえ、衝撃等でおむつが縦方向にずれる力が作用した場合であっても、おむつを身体に対して覆いづけることができる。 According to a preferred embodiment, the constriction has a ventral abdominal edge, a dorsal dorsal edge, and a lateral edge connecting the medial edges of the constriction. The first intersection where the virtual line passing through the center in the horizontal direction and extending in the vertical direction intersects the ventral edge extending from the ventral base end edge to the medial edge, and the virtual line from the dorsal base end edge. The distance from the second intersection that intersects the dorsal edge extending to the inner edge may be less than 40% of the longitudinal length of the absorption core. When the cat moves in the vertical direction, the diaper tends to shift in the vertical direction due to the impact such as landing and the vertical expansion and contraction of the skin. At this time, the amount of vertical displacement around the hind legs can be easily suppressed to 40% or less of the absorption core. Even when a force that causes the diaper to shift in the vertical direction acts due to an impact or the like, the diaper can be covered against the body.

好ましい一態様によれば、前記吸収コアの前記腹側に位置する腹外端縁と前記第１交差点との距離は、前記吸収コアの前記背側に位置する背外端縁と前記第２交差点との距離よりも長くてよい。第１交差点と第２交差点は、括れ部における横方向の中心に位置し、後脚の横方向の中心に当たり易い。括れ部における横方向の中心よりも腹側に延出する吸収コアの縦方向の長さが、括れ部における横方向の中心よりも背側に延出する吸収コアの縦方向の長さよりも長い。後脚よりも腹側に延びる吸収コアの縦方向の長さを十分に確保できるため、腹部の皮膚の伸び縮み量が大きくなった場合であっても吸収コアを追従させ続けることができ、おむつが着用された状態を維持し易い。 According to a preferred embodiment, the distance between the ventral outer edge of the absorption core and the first intersection is such that the dorsal edge of the absorption core and the second intersection. It may be longer than the distance to. The first intersection and the second intersection are located at the lateral center of the constricted portion, and easily hit the lateral center of the hind legs. The longitudinal length of the absorption core extending ventral to the lateral center of the constriction is longer than the longitudinal length of the absorption core extending dorsally from the lateral center of the constriction. .. Since the length of the absorption core extending ventral to the hind legs can be sufficiently secured, the absorption core can be kept to follow even if the amount of expansion and contraction of the skin in the abdomen becomes large, and the diaper Is easy to maintain in the worn state.

好ましい一態様によれば、前記吸収コアは、前記吸収コアの前記縦方向の中心よりも腹側に位置する腹側領域と、前記吸収コアの前記縦方向の中心よりも背側に位置する背側領域と、を有し、前記腹側領域の面積は、前記背側領域の面積よりも大きくてよい。雌の犬の排尿口は、背側領域に当たり易く、雄の犬の排尿口は、腹側領域に当たりやすい。一方、猫の排尿口は、雄の場合も雌の場合も、背側領域に当たり易い。猫のおむつにおいて、腹側領域の面積を大きくすることで、背側領域から腹側領域に拡散する体液保持することができる。また、一般的に、猫は飲水量が少ないため、泌尿器疾患にかかり易い。泌尿器疾患にかかると、多飲多尿の症状が出やすい。多尿になった場合は、吸収コアの腹側領域に拡散が広がる傾向がより顕著になる。腹側領域の面積を大きくすることで、多尿になった場合においても背側領域から腹側領域に拡散する体液保持することができる。 According to a preferred embodiment, the absorption core has a ventral region located ventral to the longitudinal center of the absorption core and a dorsal region located dorsal to the longitudinal center of the absorption core. It has a side region, and the area of the ventral region may be larger than the area of the dorsal region. The urinary opening of female dogs tends to hit the dorsal region, and the urinary opening of male dogs tends to hit the ventral region. On the other hand, the urinary opening of cats tends to hit the dorsal region in both males and females. In cat diapers, by increasing the area of the ventral region, it is possible to retain the body fluid that diffuses from the dorsal region to the ventral region. Also, in general, cats drink less water and are more susceptible to urinary diseases. Symptoms of polydipsia and polyuria are more likely to occur when suffering from urinary disorders. In the case of polyuria, the tendency for diffusion to spread to the ventral region of the absorption core becomes more pronounced. By increasing the area of the ventral region, it is possible to retain the body fluid that diffuses from the dorsal region to the ventral region even when polyuria occurs.

好ましい一態様によれば、前記吸収コアは、前記吸収コアの前記縦方向の中心よりも腹側に位置する腹側領域と、前記吸収コアの前記縦方向の中心よりも背側に位置する背側領域と、を有し、前記括れ部の内側縁における前記吸収コアの前記横方向の長さは、前記背側領域における前記吸収コアの前記横方向の最大長さに対する５０％以下であってよい。吸収コアの背側領域における横方向の最大長さと、括れ部の内側縁における吸収コアの幅と、の差を大きく設けることができる。猫の排尿口は、雄の場合も雌の場合も、背側領域に当たり易い。猫のおむつにおいて、背側領域の吸収コアの横方向の最大長さを大きくすることで、背側領域の吸収容量を確保できる。 According to a preferred embodiment, the absorption core has a ventral region located ventral to the longitudinal center of the absorption core and a dorsal region located dorsal to the longitudinal center of the absorption core. With a side region, the lateral length of the absorption core at the inner edge of the constriction is 50% or less of the maximum lateral length of the absorption core in the dorsal region. good. A large difference can be provided between the maximum lateral length of the absorption core in the dorsal region and the width of the absorption core at the inner edge of the constriction. The cat's urinary opening tends to hit the dorsal region in both males and females. In cat diapers, the absorption capacity of the dorsal region can be secured by increasing the maximum lateral length of the absorption core in the dorsal region.

好ましい一態様によれば、前記本体部には、尻尾穴が形成されており、前記尻尾穴の前記横方向の最大長さは、前記括れ部の内側縁における前記吸収コアの前記横方向の長さ以上であってよい。着用時に尻尾穴に尻尾を挿入することで、尻尾を介して尻尾穴を横方向に引っ張ることができ、吸収コアには、横方向に伸張される力がかかる。吸収コアの横方向に広げて吸収コアのよれを低減でき、着用時における吸収コアの横方向の長さを確保し易い。尻尾の横方向の最大長さが括れ部の吸収コアの横方向の長さ以上であるため、尻尾穴の横方向全域に亘って吸収コアを広げる力が作用した際に、括れ部における吸収コアの横方向の全域を広げることができる。 According to a preferred embodiment, a tail hole is formed in the main body portion, and the maximum lateral length of the tail hole is the lateral length of the absorption core at the inner edge of the constricted portion. It may be more than that. By inserting the tail into the tail hole when worn, the tail hole can be pulled laterally through the tail, and the absorption core is subjected to a force that stretches laterally. The absorption core can be expanded in the lateral direction to reduce the twist of the absorption core, and it is easy to secure the lateral length of the absorption core when worn. Since the maximum lateral length of the tail is greater than or equal to the lateral length of the absorption core in the constriction, the absorption core in the constriction when a force that spreads the absorption core over the entire lateral direction of the tail hole acts. The entire lateral direction of the can be expanded.

好ましい一態様によれば、前記尻尾穴は、前記吸収コアの前記背側に位置する背外端縁よりも背側に配置されてよい。尻尾穴が吸収コアと重ならない領域に設けられているため、尻尾を介して尻尾穴を横方向に引っ張る力が吸収コアの剛性の影響を受けにくい。そのため、尻尾を介して吸収コアのよれを低減する効果をより得やすい。 According to a preferred embodiment, the tail hole may be located dorsally of the dorsal outer edge of the absorption core. Since the tail hole is provided in a region that does not overlap with the absorption core, the force that pulls the tail hole laterally through the tail is not easily affected by the rigidity of the absorption core. Therefore, it is easier to obtain the effect of reducing the twist of the absorption core via the tail.

好ましい一態様によれば、前記吸収コアの肌対向面及び非肌対向面を覆うコアラップを有し、前記括れ部と重なる領域には、前記コアラップ同士が重なる重畳部が設けられてよい。本態様によれば、重畳部に括れ部近傍の剛性を高めることができる。吸収コアの括れ部のよれを抑制でき、フィット性を維持できる。 According to a preferred embodiment, a core wrap covering the skin-facing surface and the non-skin-facing surface of the absorption core may be provided, and a superimposing portion on which the core wraps overlap may be provided in a region overlapping the constricted portion. According to this aspect, the rigidity in the vicinity of the constricted portion can be increased in the overlapping portion. It is possible to suppress the twisting of the constricted part of the absorption core and maintain the fit.

好ましい一態様によれば前記吸収コアよりも肌側に位置する起立性の防漏ギャザーを有しており、前記防漏ギャザーは、起立可能な起立部と、前記起立部よりも前記横方向の外側に位置し、前記起立部の起立支点となる固定部と、を有し、前記固定部の内側縁は、前記括れ部の内側縁よりも前記横方向の外側に位置してよい。漏ギャザーは、固定部を基点として起立部が立ち上がるとともに、吸収コアの剛性差によって吸収コアの外側縁を基点に起立部及び固定部全体が立ち上がることがある。このとき、括れ部が設けられた領域において吸収コアの外側縁となる括れ部の内側縁よりも横方向の外側に固定部の内側縁があるため、括れ部の外側縁を基点に起立部及び固定部全体が立ち上がる。括れ部が設けられた領域では、吸収コアの横方向の長さが比較的短く、吸収コアよりも横方向の外側に体液が導かれるおそれがあるが、起立部の立ち上がる高さを確保でき、漏れを抑制できる According to a preferred embodiment, the leak-proof gathers are located on the skin side of the absorption core, and the leak-proof gathers are an upright portion and a lateral direction of the upright portion. It has a fixed portion that is located on the outside and serves as an upright fulcrum of the upright portion, and the inner edge of the fixed portion may be located on the lateral side of the inner edge of the constricted portion. In the leak gather, the upright portion may rise from the fixed portion as a base point, and the upright portion and the entire fixed portion may rise from the outer edge of the absorption core due to the difference in rigidity of the absorption core. At this time, since the inner edge of the fixed portion is laterally outside the inner edge of the constricted portion which is the outer edge of the absorption core in the region where the constricted portion is provided, the standing portion and the standing portion and the standing portion and the outer edge of the constricted portion are used as the base points. The entire fixed part stands up. In the area where the constriction is provided, the lateral length of the absorption core is relatively short, and body fluid may be guided to the outside of the absorption core in the lateral direction. Can suppress leakage

好ましい一態様によれば、前記括れ部の前記内側縁の前記縦方向の長さは、前記吸収コアの前記縦方向の長さに対する３０％以下であってよい。本態様によれば、脚幅が最も狭くなる位置に対してフィットした状態で縦方向のずれ量が吸収コアの３０％以下となる。たとえ、衝撃等でおむつが縦方向にずれる力が作用した場合であっても、おむつを身体に対して覆いづけることができる。 According to a preferred embodiment, the longitudinal length of the inner edge of the constriction may be 30% or less of the longitudinal length of the absorption core. According to this aspect, the amount of displacement in the vertical direction is 30% or less of the absorption core in a state of being fitted to the position where the leg width is the narrowest. Even when a force that causes the diaper to shift in the vertical direction acts due to an impact or the like, the diaper can be covered against the body.

猫用おむつ１を猫に装着する際は、本体第３端部６３（接合部９２が設けられた側の端部）を猫の腹に当てる。このとき、本体第４端部６４を猫の両足の間を通し、かつ猫の後側に出しておく。そして、本体部２の縦方向Ｚの中央を猫の排尿口に当てつつ、猫の尻尾を、尻尾穴７０を通しておむつの裏面側Ｔ２に出しておく。本体第４端部６４によって猫の臀部及び背中を覆う。次いで、接合部９２を猫の背中側に引っ張り、背中側に位置する本体第４端部６４のターゲット部４５に外面に接合部９２を止める。これにより、図３に示すように、猫の腹、背中、及び股下を覆うように猫用おむつ１を装着できる。すなわち、猫用おむつ１は、猫の腹側から股下を通って背側まで覆うように装着される。 When the cat diaper 1 is attached to the cat, the third end 63 of the main body (the end on the side where the joint 92 is provided) is applied to the belly of the cat. At this time, the fourth end 64 of the main body is passed between both legs of the cat and is put out to the rear side of the cat. Then, while the center of the main body 2 in the vertical direction Z is applied to the urination port of the cat, the tail of the cat is put out to T2 on the back surface side of the diaper through the tail hole 70. The fourth end 64 of the main body covers the buttocks and back of the cat. Next, the joint portion 92 is pulled toward the back side of the cat, and the joint portion 92 is fixed to the target portion 45 of the fourth end portion 64 of the main body located on the back side on the outer surface. As a result, as shown in FIG. 3, the cat diaper 1 can be worn so as to cover the cat's belly, back, and inseam. That is, the cat diaper 1 is worn so as to cover from the ventral side of the cat through the inseam to the dorsal side.

本実施の形態のおむつは、猫の脚回りに対してフィットさせ易く構成されている。次いで、猫の脚回りに対してフィットさせ易くするための構成について詳細に説明する。図４は、猫及び犬の身体の形状を模式的に示した図である。図４（ａ）は、猫の身体の形状を示しており、（ｂ）は、犬の身体の形状を示している。図１に示すように、脚回り開口部５は、腹側において本体部２の外側縁２Ｅから横方向Ｗの内側に延びる腹側辺５１と、背側において本体部２の外側縁２Ｅから横方向Ｗの内側に延びる背側辺５２と、腹側辺５１と背側辺５２を繋ぎ、縦方向Ｚに延びる縦側辺５３と、を有してよい。縦側辺５３が直線状であり、かつ腹側辺５１及び背側辺５２が曲線状の形態にあっては、腹側辺５１と縦側辺５３の境界は、直線と曲線の境界であってよい。また、腹側辺５１、背側辺５２、及び縦側辺５３がいずれも曲線状の形態にあっては、曲率が変化する箇所を境界としてよい。また、曲率が変化する境界が複数存在する形態にあっては、横方向Ｗに対して４５以下の角度で延びる部分を腹側辺５１及び背側辺５２として、縦方向Ｚに対して４５未満の角度で延びる部分を縦側辺５３として境界を設定してもよい。脚回り開口部が一定の曲率半径の円弧形状である場合には、円弧の曲率半径の中心を通り、横方向に延びる仮想線と脚回り開口部５の交点が、腹側辺５１と縦側辺５３の境界又は背側辺５２と縦側辺５３の境界であってよい。脚回り開口部５が曲率半径が変化する楕円の円弧形状である場合には、それぞれの曲率半径の中心を通り、横方向に延びる仮想線と脚回り開口部５の交点が、腹側辺５１と縦側辺５３の境界又は背側辺５２と縦側辺５３の境界であってよい。 The diaper of the present embodiment is configured to easily fit around the legs of a cat. Next, the configuration for facilitating the fit to the leg circumference of the cat will be described in detail. FIG. 4 is a diagram schematically showing the shapes of the bodies of cats and dogs. FIG. 4A shows the shape of the cat's body, and FIG. 4B shows the shape of the dog's body. As shown in FIG. 1, the leg circumference opening 5 has a ventral side 51 extending inward in the lateral direction W from the outer edge 2E of the main body 2 on the ventral side, and laterally from the outer edge 2E of the main body 2 on the dorsal side. It may have a dorsal side 52 extending inward in the direction W, and a vertical side 53 connecting the ventral side 51 and the dorsal side 52 and extending in the vertical direction Z. When the vertical side 53 is straight and the ventral side 51 and the dorsal side 52 are curved, the boundary between the ventral side 51 and the vertical side 53 is the boundary between the straight line and the curved line. You can. Further, when the ventral side 51, the dorsal side 52, and the vertical side 53 all have a curved shape, a portion where the curvature changes may be used as a boundary. Further, in a form in which there are a plurality of boundaries in which the curvature changes, the portion extending at an angle of 45 or less with respect to the lateral direction W is set as the ventral side 51 and the dorsal side 52, and is less than 45 with respect to the vertical direction Z. The boundary may be set with the portion extending at the angle of 1 as the vertical side 53. When the leg circumference opening has an arc shape with a constant radius of curvature, the intersection of the virtual line extending laterally and the leg circumference opening 5 passing through the center of the arc radius of curvature is the ventral side 51 and the vertical side. It may be the boundary of the side 53 or the boundary between the dorsal side 52 and the vertical side 53. When the leg circumference opening 5 has an elliptical arc shape in which the radius of curvature changes, the intersection of the virtual line extending laterally and the leg circumference opening 5 passing through the center of each radius of curvature is the ventral side 51. And the boundary between the vertical side 53 or the boundary between the dorsal side 52 and the vertical side 53.

図１に示すように、腹側辺５１の縦方向Ｚの長さをａとし、腹側辺５１の横方向Ｗの長さをｂとすると、ａ＜ｂを満たしてよい。腹側辺５１の縦方向Ｚの長さａは、換言すると、脚回り開口部５の腹側の端縁と、縦側辺５３と、の縦方向Ｚの距離である。腹側辺５１の横方向Ｗの長さｂは、換言すると、第１端縁６１Ｅと、縦側辺５３の腹側の端縁と、の横方向Ｗの距離である。猫におむつを装着する際は、腹側域Ｓ１を猫の腹側に当て、股下域Ｓ３を猫の股下に当てるとともに、背側域Ｓ２を猫の背側に当てた状態で、ファスニングテープ９０によって腹側域Ｓ１及び背側域Ｓ２を止着する。図３に示すように、着用状態において、脚回り開口部５が猫の後脚を囲むように配置され、脚回り開口部５の腹側辺５１は、猫の後脚の腹側の面に当たる。腹側辺５１の横方向Ｗの長さｂが腹側辺５１の縦方向Ｚの長さａよりも長いため、脚回りに対して脚回り開口部５がフィットする際に、縦方向Ｚの長さが短い範囲内で横方向Ｗに延びる領域を確保できる。例えば、ａ＝ｂの場合には、腹側辺５１の縦方向Ｚの長さと横方向Ｗの長さが同じであるため、縦方向Ｚの長い範囲内で徐々に横方向に入り込むため、脚回りに緩やかにフィットし易い。 As shown in FIG. 1, if the length of the ventral side 51 in the vertical direction Z is a and the length of the ventral side 51 in the lateral direction W is b, a <b may be satisfied. In other words, the length a of the ventral side 51 in the vertical direction Z is the distance between the ventral edge of the leg circumference opening 5 and the vertical side 53 in the vertical direction Z. The length b of the ventral side 51 in the lateral direction W is, in other words, the distance between the first edge 61E and the ventral edge of the vertical side 53 in the lateral direction W. When wearing a diaper on a cat, the fastening tape 90 is in a state where the ventral region S1 is applied to the ventral side of the cat, the inseam region S3 is applied to the inseam of the cat, and the dorsal region S2 is applied to the back side of the cat. The ventral region S1 and the dorsal region S2 are anchored by. As shown in FIG. 3, in the worn state, the leg circumference opening 5 is arranged so as to surround the hind legs of the cat, and the ventral side 51 of the leg circumference opening 5 corresponds to the ventral surface of the hind legs of the cat. .. Since the length b in the lateral direction W of the ventral side 51 is longer than the length a in the vertical direction Z of the ventral side 51, when the leg circumference opening 5 fits against the leg circumference, the vertical direction Z A region extending in the lateral direction W can be secured within a short range. For example, in the case of a = b, since the length of the ventral side 51 in the vertical direction Z and the length of the horizontal direction W are the same, the legs gradually enter the horizontal direction within the long range of the vertical direction Z. Easy to fit loosely around.

図４に示すように、出願人が鋭意調査した結果、猫における脚回りの形状と、犬における脚回りの形状と、は、大きく異なることがわかった。より詳細には、犬の脚の付け根近傍では、骨周りの肉付きが比較的少ない。また、四つん這いの状態における犬の脚は、関節で若干曲がっているものの、比較的真っすぐに延びている。これに対して、猫の脚の付け根近傍では、骨周りの肉付きが犬と比較すると多い。また、四つん這いの状態における猫の脚は、関節で大きく曲がっている。このように、猫は、脚の付け根の肉付きが多く、また付け根の関節が曲がっているため、犬と比較して脚の付け根におむつをフィットさせ難いことがあった。脚の付け根におむつがフィットしないと、着用過程でずれたり外れたりすることがあった。しかし、ａ＜ｂを満たすことにより、縦方向Ｚの短い範囲内で横方向Ｗの内側に局所的に入り込むため、脚回りに対してタイトにフィットさせ易い。脚回りにタイトにフィットさせることにより、肉付きが比較的多かったり関節が曲がっていたりして脚回りにタイトにフィットさせにくい猫に対して、使用者が意識せずに脚回りに対してタイトにフィットさせ易く、着用過程で外れる不具合を抑制できる。 As shown in FIG. 4, as a result of diligent investigation by the applicant, it was found that the shape of the leg circumference in the cat and the shape of the leg circumference in the dog are significantly different. More specifically, there is relatively little flesh around the bones near the base of the dog's leg. Also, the dog's legs on all fours are relatively straight, although they are slightly bent at the joints. On the other hand, in the vicinity of the base of the leg of a cat, the flesh around the bone is more than that of a dog. In addition, the legs of the cat on all fours are greatly bent at the joints. In this way, cats have a lot of flesh at the base of their legs, and the joints at the base are bent, so it may be difficult to fit the diaper to the base of the leg compared to dogs. If the diaper did not fit to the base of the leg, it could slip or come off during the wearing process. However, by satisfying a <b, since it locally enters the inside of the horizontal direction W within a short range in the vertical direction Z, it is easy to fit tightly to the leg circumference. By fitting tightly around the legs, it is difficult for cats that have a relatively large amount of flesh or bent joints to fit tightly around the legs. It is easy to fit and can prevent problems that come off during the wearing process.

ファスニングテープ９０と縦側辺５３の縦方向Ｚの距離をｃとし、腹側辺５１の横方向Ｗの長さをｂとすると、ｃ＜ｂを満たしてよい。ファスニングテープ９０と縦側辺５３の縦方向Ｚの距離ｃは、換言すると、腹側辺５１と縦側辺５３の境界と、ファスニングテープ９０の背側の端縁と、の縦方向Ｚの距離である。おむつを猫に装着する際には、ファスニングテープ９０を横方向に引っ張って、ターゲット部４５等に接合する。このとき、脚回り開口部５の腹側辺５１側が横方向Ｗに引っ張られ、両方の後脚の間から後脚を通って背側に延びるラインは、縦側辺５３とファスニングテープ９０を繋ぐ縦方向Ｚに延びるラインによって構成される。距離ｃが腹側辺５１の横方向Ｗの長さｂよりも短いため、脚回りに対して脚回り開口部５がフィットする際に、縦方向Ｚの長さが短い範囲内で横方向Ｗに延びる領域を確保できる。縦方向Ｚの短い範囲内で横方向に局所的に入り込むため、脚回りに対してタイトにフィットさせ易い。脚回りにタイトにフィットさせることにより、着用過程で外れる不具合を抑制できる。 Assuming that the distance between the fastening tape 90 and the vertical side 53 in the vertical direction Z is c and the length of the ventral side 51 in the horizontal direction W is b, c <b may be satisfied. In other words, the distance c in the vertical direction Z between the fastening tape 90 and the vertical side 53 is the distance Z in the vertical direction between the boundary between the ventral side 51 and the vertical side 53 and the dorsal edge of the fastening tape 90. Is. When the diaper is attached to the cat, the fastening tape 90 is pulled laterally to be joined to the target portion 45 or the like. At this time, the ventral side 51 side of the leg circumference opening 5 is pulled in the lateral direction W, and the line extending from between both rear legs to the dorsal side through the rear legs connects the vertical side 53 and the fastening tape 90. It is composed of lines extending in the vertical direction Z. Since the distance c is shorter than the length b of the lateral direction W of the ventral side 51, when the leg circumference opening 5 fits the leg circumference, the lateral direction W is within a range in which the length of the vertical direction Z is short. It is possible to secure an area extending to. Since it locally enters in the horizontal direction within a short range in the vertical direction Z, it is easy to fit tightly to the leg circumference. By fitting it tightly around the legs, it is possible to prevent problems that come off during the wearing process.

本体部２の縦方向Ｚの長さをｄとすると、ｄに対する腹側辺５１の縦方向Ｚの長さａの比率は、１０％以下であってよい。本体部２の縦方向Ｚの長さｄは、換言すると、第３端縁６３Ｅと第４端縁６４Ｅの縦方向Ｚの距離である。なお、本体部２の縦方向Ｚの長さは、猫用おむつ１の縦方向Ｚの全長であってもよい。本体部２全体に対する腹側辺５１の縦方向の長さａの比率が低いため、脚回りに対する縦方向Ｚのずれを抑制できる。縦方向Ｚのずれ量が多くなることに起因しておむつが着用時に外れたり、脚の前後の動きを阻害したりする不具合を抑制できる。 Assuming that the length Z of the main body 2 in the vertical direction is d, the ratio of the length a of the ventral side 51 in the vertical direction Z to d may be 10% or less. In other words, the length d of the main body 2 in the vertical direction Z is the distance between the third edge 63E and the fourth edge 64E in the vertical direction Z. The length of the main body 2 in the vertical direction Z may be the total length of the cat diaper 1 in the vertical direction Z. Since the ratio of the length a of the ventral side 51 to the entire main body 2 in the vertical direction is low, the deviation of the vertical direction Z with respect to the leg circumference can be suppressed. It is possible to suppress problems such as the diaper coming off when worn or hindering the front-back movement of the legs due to the large amount of displacement in the vertical direction Z.

腹側辺５１とターゲット部４５の縦方向の距離をｅとすると、本体部２の縦方向Ｚの長さｄに対するｅの比率は、６０％以上であってよい。腹側辺５１とターゲット部４５の縦方向の距離は、換言すると、腹側辺５１と縦側辺５３の境界とターゲット部４５の縦方向の距離である。縦方向Ｚにおいて腹側辺５１とターゲット部４５の間の領域は、ファスニングテープ９０をターゲット部４５等に止着した状態で、腹側から背側にかけて身体を覆っており、身体の動きや皮膚の伸び縮みに追従して変形する領域である。本体部２全体に対するｅの長さの比率が高いため、猫の動き等に応じて変形する領域を広く確保できる。また、出願人が鋭意調査した結果、猫と犬で普段の身体の動かし方が大きく異なることがわかった。より詳細には、犬は、地面を走る等、平面方向の動きが多く、猫は、犬と比較して、ジャンプしたり飛び降りたりする等の垂直方向の動きが多いことがわかった。垂直方向に身体を動かそうとすると、後足を曲げた状態から一気に伸ばしたり、脚の曲げ伸ばしとともに腹を凹ませた状態及び背中を丸めた状態から延ばしたりして、腹部、臀部及び足回りの皮膚の伸び縮み量が大きくなり易い。ｅの長さを確保することにより、垂直方向に身体を動かした際におむつを追従させることができ、おむつが意図せずにずれることを抑制できる。 Assuming that the vertical distance between the ventral side 51 and the target portion 45 is e, the ratio of e to the length d in the vertical direction Z of the main body portion 2 may be 60% or more. The vertical distance between the ventral side 51 and the target portion 45 is, in other words, the vertical distance between the boundary between the ventral side 51 and the vertical side 53 and the target portion 45. The region between the ventral side 51 and the target portion 45 in the vertical direction Z covers the body from the ventral side to the dorsal side with the fastening tape 90 fixed to the target portion 45 or the like, and the movement of the body and the skin. It is a region that deforms following the expansion and contraction of. Since the ratio of the length of e to the entire main body 2 is high, a wide area that deforms according to the movement of the cat can be secured. In addition, as a result of diligent investigation by the applicant, it was found that the way of normal physical movement differs greatly between cats and dogs. More specifically, it was found that dogs have more movements in the plane direction such as running on the ground, and cats have more movements in the vertical direction such as jumping and jumping than dogs. When trying to move the body in the vertical direction, the abdomen, buttocks and undercarriage may be extended from the bent hind legs at a stretch, or from the bent and extended legs and the dented abdomen and the rounded back. The amount of expansion and contraction of the skin tends to increase. By ensuring the length of e, the diaper can be made to follow when the body is moved in the vertical direction, and the diaper can be prevented from being unintentionally displaced.

尻尾穴７０の背側の端縁とターゲット部４５の縦方向Ｚの距離をｆとすると、本体部２の縦方向Ｚの長さｄに対するｆの比率は、２０％以上であってよい。尻尾穴７０の背側の端縁とターゲット部４５の縦方向Ｚの距離ｆは、ファスニングテープ９０をターゲット部４５に止着した状態で、尻尾穴７０から背側にかけた領域を覆う領域の長さであり、背側における身体の動きや皮膚の伸び縮みに追従して変形する領域の長さである。猫は、犬と比較して、背中を丸めて伸びをしたり、背中を丸めて座ったり、背中を丸くする姿勢をとることが多い。背中を丸めた姿勢を取ったり、背中を伸ばした姿勢を取ったりすると、背中の動きや皮膚の伸び縮み量が大きい。本体部２全体に対するｆの長さの比率が高いため、猫の動き等に応じて変形する領域を背側において広く確保でき、おむつを背側の動きに追従させ、おむつが意図せずにずれることを抑制できる。また、好適には、尻尾穴（穴本体部７１＋切り込み部７２）７０とターゲット部４５の縦方向Ｚの距離ｆは、本体部２の縦方向Ｚの長さｄに対する２０％以上であってよい。尻尾穴（穴本体部７１＋切り込み部７２）７０とターゲット部４５の縦方向Ｚの距離ｆは、切り込み部７２によって尻尾穴の開口を拡大した状態において背側における身体の動きや皮膚の伸び縮みに追従して変形する領域の長さである。当該構成によれは、切り込み部７２によって尻尾穴７０の寸法を大きくした場合であっても、猫の動き等に応じて変形する領域を背側において広く確保でき、おむつを背側の動きに追従させ、おむつが意図せずにずれることを抑制できる。 Assuming that the distance between the dorsal edge of the tail hole 70 and the target portion 45 in the vertical direction Z is f, the ratio of f to the length d in the vertical direction Z of the main body portion 2 may be 20% or more. The distance f between the dorsal edge of the tail hole 70 and the vertical direction Z of the target portion 45 is the length of the region covering the region extending from the tail hole 70 to the dorsal side with the fastening tape 90 anchored to the target portion 45. It is the length of the region that deforms following the movement of the body on the dorsal side and the expansion and contraction of the skin. Compared to dogs, cats often take a posture of curling up and stretching, sitting with their backs curled up, and curling their backs. If you take a posture with your back curled up or with your back extended, the movement of your back and the amount of expansion and contraction of your skin will be large. Since the ratio of the length of f to the entire main body 2 is high, a wide area that deforms according to the movement of the cat can be secured on the dorsal side, the diaper is made to follow the movement of the dorsal side, and the diaper shifts unintentionally. Can be suppressed. Further, preferably, the distance f between the tail hole (hole main body portion 71 + cut portion 72) 70 and the target portion 45 in the vertical direction Z may be 20% or more with respect to the length d in the vertical direction Z of the main body portion 2. .. The distance f between the tail hole (hole body 71 + notch 72) 70 and the target portion 45 in the vertical direction Z is for the movement of the body on the dorsal side and the expansion and contraction of the skin in a state where the opening of the tail hole is enlarged by the notch 72. It is the length of the region that follows and deforms. According to this configuration, even when the size of the tail hole 70 is increased by the notch 72, a wide area that deforms according to the movement of the cat can be secured on the dorsal side, and the diaper follows the movement on the dorsal side. It is possible to prevent the diaper from slipping unintentionally.

穴本体部７１の縦方向Ｚの最大長さをｇとすると、腹側辺５１とターゲット部４５の縦方向Ｚの距離ｅに対するｇの比率は、３．５０％以下であってよい。犬は、比較的左右方向に尻尾を動かすことが多く、猫は、比較して上下方向に尻尾を動かすことが多い。そのため、猫がおむつを着用した状態では、穴本体部７１が縦方向に引っ張られ、おむつが縦方向Ｚにずれやすい。このとき、可動域に対する穴本体部７１の縦方向の長さの比率が低いため、穴本体部７１を介しておむつが縦方向Ｚにずれる量を抑制できる。また、尻尾穴の縦方向の最大長さをｈとすると、腹側辺５１とターゲット部４５の縦方向Ｚの距離ｅに対するｈの比率は、５．５％以下であってよい。尻尾穴７０の縦方向Ｚの最大長ｈは、尻尾穴（穴本体部７１＋切り込み部７２）７０の縦方向Ｚの最大長さである。当該構成によれは、切り込み部７２によって尻尾穴７０の寸法を大きくした場合において、可動域に対する尻尾穴７０の縦方向の長さの比率を低くし、尻尾穴７０を介しておむつが縦方向Ｚにずれる量を抑制できる。 Assuming that the maximum length of the hole main body portion 71 in the vertical direction Z is g, the ratio of g to the distance e of the ventral side 51 and the target portion 45 in the vertical direction Z may be 3.50% or less. Dogs often move their tails relatively left and right, and cats often move their tails up and down in comparison. Therefore, when the cat wears the diaper, the hole main body 71 is pulled in the vertical direction, and the diaper tends to shift in the vertical direction Z. At this time, since the ratio of the length of the hole main body 71 in the vertical direction to the range of motion is low, the amount of the diaper shifting in the vertical direction Z via the hole main body 71 can be suppressed. Further, assuming that the maximum length of the tail hole in the vertical direction is h, the ratio of h to the distance e of the ventral side 51 and the target portion 45 in the vertical direction Z may be 5.5% or less. The maximum length h of the tail hole 70 in the vertical direction Z is the maximum length h of the tail hole (hole body portion 71 + cut portion 72) 70 in the vertical direction Z. According to this configuration, when the size of the tail hole 70 is increased by the notch 72, the ratio of the length of the tail hole 70 to the range of motion in the vertical direction is lowered, and the diaper is formed in the vertical direction Z through the tail hole 70. The amount of deviation can be suppressed.

吸収コア３０の横方向Ｗの最大長さに対する穴本体部７１の横方向Ｗの最大長さの比率は、３５％以上であってよい。着用時に尻尾穴７０に尻尾を挿入することで、尻尾を介して尻尾穴７０の穴本体部７１を横方向Ｗに引っ張ることができ、吸収コア３０には、横方向Ｗに伸長される力がかかる。吸収コア３０の横方向Ｗに広げて吸収コア３０のよれを低減でき、着用時における吸収コア３０の横方向Ｗの長さを確保し易い。特に猫は、犬と比較して、胴回り寸法に対する尻尾の径の比率が高い。よって、尻尾を介して吸収コア３０のよれを低減する効果を得やすい。吸収コア３０のよれを広げることができ、着用時における吸収コア３０の横方向Ｗの長さを確保し易い。また、吸収コア３０の横方向Ｗの最大長さに対する穴本体部７１の横方向Ｗの最大長さの比率が高いため、穴本体部７１を介して吸収コア３０を広げる力が吸収コア３０の横方向Ｗ全域に伝達し易い。吸収コア３０の変形に起因してフィット性が低下し難く、体液の漏れを抑制できるとともに、着用時に猫が足を動きかし易い状態を維持できる。また、好適には、吸収コア３０の横方向Ｗの最大長さに対する尻尾穴（穴本体部７１＋切り込み部７２）７０の横方向Ｗの最大長さに比率は、４０％超であってよい。当該構成によれは、切り込み部７２によって尻尾穴７０の寸法を大きくした場合において、吸収コア３０の横方向の最大長さに対する穴本体部７１の横方向の最大長さの比率が高いため、尻尾穴７０を介して吸収コア３０を広げる力が吸収コア３０の横方向Ｗ全域により伝達し易い。また、尻尾穴７０は、吸収コア３０の背側に位置する背外端縁Ｒ３０よりも背側に配置されてよい。尻尾穴７０が吸収コア３０と重ならない領域に設けられているため、尻尾を介して尻尾穴７０を横方向Ｗに引っ張る力が吸収コア３０の剛性の影響を受けにくい。そのため、尻尾を介して吸収コア３０のよれを低減する効果をより得やすい。 The ratio of the maximum length of the horizontal direction W of the hole main body 71 to the maximum length of the horizontal direction W of the absorption core 30 may be 35% or more. By inserting the tail into the tail hole 70 at the time of wearing, the hole body 71 of the tail hole 70 can be pulled laterally W through the tail, and the absorption core 30 has a force extending in the lateral direction W. It takes. It is possible to reduce the twist of the absorption core 30 by expanding it in the lateral direction W of the absorption core 30, and it is easy to secure the length of the absorption core 30 in the lateral direction W when worn. In particular, cats have a higher ratio of tail diameter to waist circumference than dogs. Therefore, it is easy to obtain the effect of reducing the twist of the absorption core 30 via the tail. The twist of the absorption core 30 can be widened, and it is easy to secure the length of the absorption core 30 in the lateral direction W when worn. Further, since the ratio of the maximum length of the hole main body 71 to the maximum length of the horizontal W of the absorption core 30 is high, the force to spread the absorption core 30 through the hole main body 71 is the force of the absorption core 30. It is easy to transmit to the entire lateral direction W. The fit is unlikely to deteriorate due to the deformation of the absorption core 30, the leakage of body fluid can be suppressed, and the state in which the cat can easily move its legs when worn can be maintained. Further, preferably, the ratio of the tail hole (hole body portion 71 + cut portion 72) 70 to the maximum length of the lateral W of the absorption core 30 to the maximum length of the lateral W of the absorption core 30 may be more than 40%. According to this configuration, when the size of the tail hole 70 is increased by the notch 72, the ratio of the maximum lateral length of the hole main body 71 to the maximum lateral length of the absorption core 30 is high, so that the tail is tailed. The force that spreads the absorption core 30 through the hole 70 is easily transmitted over the entire lateral direction W of the absorption core 30. Further, the tail hole 70 may be arranged on the dorsal side of the dorsal outer edge R30 located on the dorsal side of the absorption core 30. Since the tail hole 70 is provided in a region that does not overlap with the absorption core 30, the force that pulls the tail hole 70 laterally through the tail is not easily affected by the rigidity of the absorption core 30. Therefore, it is easier to obtain the effect of reducing the twist of the absorption core 30 via the tail.

次いで、図５に基づいて吸収コア３０について詳細に説明する。図５は、吸収コア３０の拡大平面図である。吸収コア３０は、横方向Ｗの内側に括れる括れ部３１を有してよい。括れ部３１は、吸収コア３０の外側縁３０Ｅから横方向Ｗの内側に凹んでいる部分である。括れ部３１の内側縁３１Ｄは、括れ部３１において最も横方向の内側に位置する部分であり、括れ部３１の外側縁３１Ｅは、括れ部３１において最も横方向Ｗの外側に位置する部分であり、吸収コア３０の外側縁３０Ｅに一致してよい。括れ部３１の横方向Ｗの内側縁３１Ｄにおける腹側の端縁Ｐ３１１は、吸収コア３０の縦方向Ｚの中心ＣＺ３０よりも背側に位置してよい。本実施の形態のように、括れ部３１の内側縁３１Ｄが縦方向Ｚに延びていない構成にあっては、腹側の端縁Ｐ３１１は、点であり、括れ部３１の内側縁３１Ｄにおける背側の端縁Ｐ３１２と一致している。しかし、括れ部３１の内側縁３１Ｄの縦方向Ｚに延びている構成にあっては、腹側の端縁Ｐ３１１は、縦方向Ｚに延びる内側縁３１Ｄにおいて最も腹側に位置する縁であり、背側の端縁Ｐ３１２と縦方向Ｚに離間している。 Next, the absorption core 30 will be described in detail with reference to FIG. FIG. 5 is an enlarged plan view of the absorption core 30. The absorption core 30 may have a constricted portion 31 constricted inside in the lateral direction W. The constricted portion 31 is a portion recessed inward in the lateral direction W from the outer edge 30E of the absorption core 30. The inner edge 31D of the constricted portion 31 is a portion of the constricted portion 31 located on the innermost side in the lateral direction, and the outer edge 31E of the constricted portion 31 is a portion of the constricted portion 31 located on the outermost side of the lateral direction W. , May coincide with the outer edge 30E of the absorption core 30. The ventral edge P311 of the inner edge 31D of the constriction portion 31 in the lateral direction W may be located dorsal to the center CZ30 of the absorption core 30 in the longitudinal direction Z. In the configuration in which the inner edge 31D of the constricted portion 31 does not extend in the vertical direction Z as in the present embodiment, the ventral end edge P311 is a point, and the dorsal edge 31D of the constricted portion 31 at the inner edge 31D. It coincides with the side edge P312. However, in the configuration extending in the vertical direction Z of the inner edge 31D of the constricted portion 31, the ventral end edge P311 is the most ventral edge of the inner edge 31D extending in the vertical direction Z. It is separated from the dorsal edge P312 in the vertical direction Z.

図３に示すように、着用状態において、脚回り開口部５が猫の後脚を囲むように配置され、吸収コア３０の括れ部３１の内側縁３１Ｄは、後脚から臀部にかけて脚幅（両脚同士の間隔）が最も狭くなる部分１０５（図４参照）を中心としてフィットする。このとき、従来の犬と猫の兼用のおむつにあっては、括れ部３１の内側縁３１Ｄにおける腹側の端縁Ｐ３１１が、吸収コア３０の縦方向Ｚの中心ＣＺ３０又は腹側に偏倚して配置されている。そのため、脚幅が最も狭くなる位置よりも腹側に延出する吸収コア３０の縦方向Ｚの長さを十分に確保できなかった。そのため、猫の垂直方向の動きに伴って腹部の皮膚の伸び縮み量が大きくなった場合に、吸収コア３０を追従させ続けることができず、おむつがずれたり外れたりする不具合があった。また、猫が垂直方向に動かそうとして後足を曲げたり延ばしたりすると、脚幅が最も狭くなる位置１０５よりも腹側に延出する吸収コア３０が繰り返し変形し、身体を覆い続け難いことがあった。出願人が猫の着用状態を観察した結果、脚幅が最も狭くなる位置１０５よりも腹側に延出する吸収コア３０の縦方向Ｚの長さは、腹側の端縁Ｐ３１１よりも腹側に延びる吸収コア３０の縦方向の長さに相当することがわかった。括れ部３１の横方向Ｗの内側縁３１Ｄにおける腹側の端縁Ｐ３１１が吸収コアの縦方向Ｚの中心ＣＺ３０よりも背側に位置していることにより、脚幅が最も狭くなる位置１０５よりも腹側に延出する吸収コア３０の縦方向Ｚの長さを十分に確保できる。そのため、垂直方向の動きによって脚を繰り返し前後に動かした場合であっても吸収コア３０によって身体を覆うことができる。また、脚幅が最も狭くなる位置１０５よりも腹側に延出する吸収コア３０の縦方向Ｚの長さを十分に確保できるため、腹部の皮膚の伸び縮み量が大きくなった場合であっても吸収コアを追従させ続けることができ、おむつが着用された状態を維持し易い。 As shown in FIG. 3, in the worn state, the leg circumference opening 5 is arranged so as to surround the hind legs of the cat, and the inner edge 31D of the constricted portion 31 of the absorption core 30 has a leg width (both legs) from the hind legs to the buttocks. It fits around the portion 105 (see FIG. 4) where the distance between the two is the narrowest. At this time, in the conventional diaper for both dog and cat, the ventral end edge P311 in the inner edge 31D of the constricted portion 31 is biased toward the center CZ30 or the ventral side in the vertical direction Z of the absorption core 30. Have been placed. Therefore, it was not possible to secure a sufficient length of the absorption core 30 extending ventral to the ventral side from the position where the leg width is the narrowest in the vertical direction Z. Therefore, when the amount of expansion and contraction of the skin in the abdomen increases with the vertical movement of the cat, the absorption core 30 cannot continue to follow, and there is a problem that the diaper shifts or comes off. In addition, when the cat bends or extends its hind legs in an attempt to move in the vertical direction, the absorption core 30 extending ventral to the position 105 where the leg width is the narrowest is repeatedly deformed, making it difficult to continue covering the body. there were. As a result of the applicant observing the wearing state of the cat, the length of the absorption core 30 extending ventral to the position 105 where the leg width is the narrowest is ventral to the ventral edge P311. It was found that it corresponds to the vertical length of the absorption core 30 extending to. Since the ventral end edge P311 in the inner edge 31D of the lateral direction W of the constricted portion 31 is located on the dorsal side of the center CZ30 of the vertical direction Z of the absorption core, the leg width is smaller than the position 105 where the leg width is the narrowest. A sufficient length of the absorption core 30 extending to the ventral side in the vertical direction Z can be secured. Therefore, the body can be covered by the absorption core 30 even when the legs are repeatedly moved back and forth by the vertical movement. Further, since the length Z in the vertical direction of the absorption core 30 extending ventrally from the position 105 where the leg width is the narrowest can be sufficiently secured, the amount of expansion and contraction of the skin in the abdomen becomes large. Can keep the absorption core following, making it easier to keep the diaper on.

括れ部３１の内側縁３１Ｄの縦方向Ｚの長さＺ３１Ｄ（図７参照）は、吸収コア３０の縦方向Ｚの長さＺ３０に対する３０％以下であってよい。なお、本実施の形態の括れ部３１の内側縁３１Ｄは、点状であり、内側縁３１Ｄの縦方向Ｚの長さは、限りなく０に近い値である。猫が垂直方向に動くと、着地等の衝撃や皮膚の縦方向の伸び縮みに起因して、おむつが縦方向Ｚにずれ易くなる。このとき、括れ部３１の内側縁３１Ｄの長さが３０％以下であるため、脚幅が最も狭くなる位置１０５に対してフィットした状態で縦方向Ｚのずれ量が吸収コアの３０％以下となる。たとえ、衝撃等でおむつがずれる方向に力が作用した場合であっても、おむつを身体に対して覆いづけることができる。また、内側縁３１Ｄの縦方向Ｚの長さＺ３１Ｄは、括れ部３１の縦方向Ｚの長さＺ３１に対する４０％以下であってよい。括れ部３１内において内側縁３１Ｄが占める縦方向Ｚの長さの比率が低いため、おむつの縦方向Ｚのずれ量を抑えることができる。 The length Z31D (see FIG. 7) of the inner edge 31D of the constricted portion 31 in the vertical direction Z may be 30% or less of the length Z30 in the vertical direction Z of the absorption core 30. The inner edge 31D of the constricted portion 31 of the present embodiment is point-shaped, and the length of the inner edge 31D in the vertical direction Z is as close to 0 as possible. When the cat moves in the vertical direction, the diaper tends to shift in the vertical direction Z due to the impact such as landing and the vertical expansion and contraction of the skin. At this time, since the length of the inner edge 31D of the constricted portion 31 is 30% or less, the amount of deviation in the vertical direction Z is 30% or less of the absorption core in a state of being fitted to the position 105 where the leg width is the narrowest. Become. Even when a force acts in the direction in which the diaper shifts due to an impact or the like, the diaper can be covered against the body. Further, the length Z31D of the inner edge 31D in the vertical direction Z may be 40% or less of the length Z31 of the constricted portion 31 in the vertical direction Z. Since the ratio of the length of the vertical direction Z occupied by the inner edge 31D in the constricted portion 31 is low, the amount of displacement of the diaper in the vertical direction Z can be suppressed.

括れ部３１は、腹側に位置する腹基端縁３１１、背側に位置する背基端縁３１２、及び内側縁３１Ｄを繋ぐ側縁３３を有している。腹基端縁３１１は、括れ部３１において最も腹側に位置する縁であり、背基端縁３１２は、括れ部３１において最も背側に位置する縁である。側縁３３は、腹基端縁３１１から内側縁３１Ｄに延びる腹側縁Ｆ３３と、背基端縁３１２から内側縁３１Ｄに延びる背側縁Ｒ３３と、を有する。腹側縁Ｆ３３と背側縁Ｒ３３は、横方向Ｗに延びる横仮想線に対して対称でなく、非対称であってよい。腹側縁Ｆ３３は、腹基端縁３１１から背側に向かって直線状に延びる部分ＳＦ３３と、直線状に延びる部分ＳＦ３３と内側縁３１Ｄを曲線状に繋ぐ部分ＣＦ３３と、を有する。直線状に延びる部分ＳＦ３３は、縦方向Ｚに対して角度α傾斜している。角度αは、曲線状に繋ぐ部分ＣＦ３３の縦方向Ｚに対する傾斜角度よりも小さい。また、腹側縁Ｆ３３において、直線状に延びる部分ＳＦ３３の縦方向Ｚの長さは、曲線状に繋ぐ部分ＣＦ３３の縦方向Ｚの長さよりも短い。よって、腹側縁Ｆ３３は、括れ部３１のうち縦方向Ｚの半分以上の領域で緩やかに横方向Ｗに凹み、括れ部３１の縦方向Ｚの短い範囲で横方向Ｗに局所的に凹む形状である。そのため、猫の脚回りにおける縦方向Ｚのずれをより抑制できる。また、背側縁Ｒ３３は、背基端縁３１２から内側縁３１Ｄに向けて曲線状に延びており、直線状に延びる部分を有していない。 The constricted portion 31 has a ventral base end edge 311 located on the ventral side, a dorsal base end edge 312 located on the dorsal side, and a side edge 33 connecting the inner edge 31D. The abdominal base end edge 311 is the most ventral edge of the constriction 31, and the dorsal base end edge 312 is the most dorsal edge of the constriction 31. The side edge 33 has a ventral edge F33 extending from the ventral base edge 311 to the medial edge 31D and a dorsal edge R33 extending from the dorsal base edge 312 to the medial edge 31D. The ventral edge F33 and the dorsal edge R33 may be asymmetric rather than symmetrical with respect to the lateral virtual line extending in the lateral direction W. The ventral edge F33 has a portion SF33 extending linearly from the ventral base end edge 311 toward the dorsal side, and a portion CF33 connecting the linearly extending portion SF33 and the inner edge 31D in a curved line. The linearly extending portion SF33 is inclined at an angle α with respect to the vertical direction Z. The angle α is smaller than the inclination angle of the curvedly connected portion CF33 with respect to the vertical direction Z. Further, in the ventral edge F33, the length of the portion SF33 extending linearly in the vertical direction Z is shorter than the length of the portion CF33 connected in a curved shape in the vertical direction Z. Therefore, the ventral edge F33 has a shape in which the constricted portion 31 is gently recessed in the lateral direction W in a region equal to or more than half of the vertical direction Z, and is locally recessed in the lateral direction W in a short range of the constricted portion 31 in the vertical direction Z. Is. Therefore, the deviation of the vertical Z in the leg circumference of the cat can be further suppressed. Further, the dorsal edge R33 extends in a curved line from the dorsal base end edge 312 toward the inner edge 31D, and does not have a portion extending in a straight line.

括れ部３１の横方向Ｗの中心を通り、かつ縦方向に延びる仮想線ＷＬ３１が、腹側縁Ｆ３３と交差する第１交差点Ｐ１と、仮想線ＷＬ３１が、背側縁Ｒ３３と交差する第２交差点Ｐ２と、の距離Ｇ１２は、吸収コア３０の縦方向Ｚの長さＺ３０に対する４０％未満であってよい。第１交差点Ｐ１と第２交差点Ｐ２の距離Ｇ１２は、括れ部３１の横方向Ｗの中心における括れ部３１の縦方向Ｚの長さであり、吸収コア３０が後脚に密着せずに縦方向Ｚに吸収コアがずれ易い範囲の長さとなる。第１交差点Ｐ１と第２交差点Ｐ２の距離Ｇ１２が吸収コア３０の縦方向Ｚの長さＺ３０に対する４０％未満であることにより、後脚の周囲における縦方向Ｚのずれ量が吸収コア３０の４０％以下に抑え易い。たとえ、衝撃等でおむつが縦方向Ｚにずれる力が作用した場合であっても、おむつを身体に対して覆いづけることができる。 The first intersection P1 where the virtual line WL31 which passes through the center of the constriction portion 31 in the lateral direction and extends in the vertical direction intersects the ventral edge F33, and the second intersection where the virtual line WL31 intersects the dorsal edge R33. The distance G12 from P2 may be less than 40% of the length Z30 of the absorption core 30 in the longitudinal direction Z. The distance G12 between the first intersection P1 and the second intersection P2 is the length of the constricted portion 31 in the vertical direction Z at the center of the lateral direction W of the constricted portion 31, and the absorption core 30 does not come into close contact with the hind legs in the vertical direction. The length is within the range in which the absorption core easily shifts to Z. Since the distance G12 between the first intersection P1 and the second intersection P2 is less than 40% of the length Z30 of the absorption core 30 in the vertical direction Z, the amount of deviation of the vertical Z around the hind legs is 40 of the absorption core 30. Easy to keep below%. Even when a force that causes the diaper to shift in the vertical direction Z is applied due to an impact or the like, the diaper can be covered against the body.

吸収コア３０の括れ部３１において腹側に向かって延びる腹側縁Ｆ３３の少なくとも一部は、内側縁３１Ｄから腹側に向かって横方向Ｗの外側に延びてよい。より詳細には、腹側縁Ｆ３３のうち、腹基端縁３１１から背側に直線状に延びる部分ＳＦ３３及び曲線状に延びる部分ＣＦ３３は、それぞれ内側縁３１Ｄから腹側に向かって横方向Ｗの外側に延びている。括れ部３１の内側縁３１Ｄにおいて吸収コア３０の横方向Ｗの長さを短くして、猫の両脚の横方向の長さが短い部分に吸収コア３０をフィットさせ易い。特に、猫は、犬よりも脚幅が狭く、吸収コア３０の横方向Ｗの長さが短くなっていることにより、猫の体形により好適にフィットさせることができる。また、括れ部３１の内側縁３１Ｄから腹側に向かって横方向Ｗの長さが長くなっているため、括れ部３１の内側縁３１Ｄにおける吸収コア３０の横方向Ｗの長さを短くしつつも、腹側における吸収コア３０の面積を確保できる。また、脚回り開口部５の縦側辺５３は、腹側から背側に向かって横方向Ｗの外側に延びてよい。腹側から背側に向かって横方向Ｗの外側に延びる部分は、内側縁３１Ｄよりも腹側の領域から内側縁よりも背側の領域を跨いでいる。脚回り開口部５の縦側辺５３は、背側から腹側に向かって横方向Ｗの内側に延びており、吸収コア３０の外側縁と逆の傾斜となる。そのため、吸収コア３０の横方向Ｗの長さを短くした部分において、脚回り開口部５の横方向Ｗの長さを長く設けることができ、おむつ全体として胴回りを覆い続け、漏れやずれを抑制できる。 At least a part of the ventral edge F33 extending ventrally in the constricted portion 31 of the absorption core 30 may extend laterally outward from the medial edge 31D toward the ventral side. More specifically, of the ventral edge F33, the portion SF33 extending linearly from the ventral base end edge 311 to the dorsal side and the portion CF33 extending linearly from the medial edge 31D to the ventral side are laterally W, respectively. It extends outward. The length of the absorption core 30 in the lateral direction W is shortened at the inner edge 31D of the constricted portion 31, so that the absorption core 30 can be easily fitted to the portion where the lateral length of both legs of the cat is short. In particular, the cat has a narrower leg width than the dog and the length of the lateral W of the absorption core 30 is shorter, so that the cat can be fitted more favorably to the body shape of the cat. Further, since the length of the lateral direction W increases from the inner edge 31D of the constricted portion 31 toward the ventral side, the length of the lateral W of the absorption core 30 at the inner edge 31D of the constricted portion 31 is shortened. Also, the area of the absorption core 30 on the ventral side can be secured. Further, the vertical side 53 of the leg circumference opening 5 may extend outward in the lateral direction W from the ventral side to the dorsal side. The portion extending outward in the lateral direction W from the ventral side to the dorsal side straddles the region on the ventral side of the medial edge 31D and the region on the dorsal side of the medial edge. The vertical side 53 of the leg circumference opening 5 extends inward in the lateral direction W from the dorsal side to the ventral side, and has an inclination opposite to the outer edge of the absorption core 30. Therefore, in the portion where the length of the lateral W of the absorption core 30 is shortened, the length of the lateral W of the leg circumference opening 5 can be increased, and the diaper as a whole continues to cover the waist circumference to suppress leakage and slippage. can.

吸収コア３０は、腹側に位置する腹外端縁Ｆ３０と、背側に位置する背外端縁Ｒ３０と、を有する。腹外端縁Ｆ３０は、吸収コア３０において最も腹側に位置する縁であり、背外端縁Ｒ３０は、吸収コア３０において最も腹側に位置する縁である。腹外端縁Ｆ３０と第１交差点Ｐ１の距離ＧＦ３０は、背外端縁Ｒ３０と第２交差点Ｐ２との距離ＧＲ３０よりも長くてよい。第１交差点Ｐ１と第２交差点Ｐ２は、括れ部３１における横方向Ｗの中心に位置し、猫の後脚の横方向Ｗの中心に当たり易い。括れ部３１における横方向Ｗの中心よりも腹側に延出する吸収コア３０の縦方向Ｚの長さが、括れ部３１における横方向Ｗの中心よりも背側に延出する吸収コア３０の縦方向Ｚの長さよりも長い。後脚よりも腹側に延びる吸収コア３０の縦方向Ｚの長さを十分に確保できるため、腹部の皮膚の伸び縮み量が大きくなった場合であっても吸収コア３０を追従させ続けることができ、おむつが着用された状態を維持し易い。また、後脚よりも腹側に延びる吸収コア３０の縦方向Ｚの長さを確保するために、括れ部３１の内側縁３１Ｄの少なくとも一部は、吸収コア３０の縦方向Ｚの中心ＣＺ３０よりも腹側に位置してよい。 The absorption core 30 has a ventral outer edge F30 located on the ventral side and a dorsal outer edge R30 located on the dorsal side. The ventral outer edge F30 is the most ventral edge of the absorption core 30, and the dorsolateral edge R30 is the most ventral edge of the absorption core 30. The distance GF30 between the ventral outer edge F30 and the first intersection P1 may be longer than the distance GR30 between the dorsolateral edge R30 and the second intersection P2. The first intersection P1 and the second intersection P2 are located at the center of the lateral direction W in the constricted portion 31, and easily hit the center of the lateral direction W of the hind legs of the cat. The length of the absorption core 30 extending ventral to the ventral side of the center of the lateral direction W in the constricted portion 31 is the length of the absorption core 30 extending to the dorsal side of the center of the lateral direction W in the constricted portion 31. It is longer than the length in the vertical direction Z. Since the length Z of the absorption core 30 extending ventral to the hind legs can be sufficiently secured, the absorption core 30 can be continuously followed even when the amount of expansion and contraction of the skin in the abdomen becomes large. It is easy to keep the diaper on. Further, in order to secure the length of the absorption core 30 extending ventral to the hind legs in the vertical direction Z, at least a part of the inner edge 31D of the constricted portion 31 is from the center CZ30 of the absorption core 30 in the vertical direction Z. May also be located on the ventral side.

吸収コア３０は、吸収コア３０の縦方向Ｚの中心ＣＺ３０よりも腹側に位置する腹側領域ＲＦ３０と、吸収コア３０の縦方向Ｚの中心ＣＺ３０よりも背側に位置する背側領域ＲＲ３０と、を有する。腹側領域ＲＦ３０の面積は、背側領域ＲＲ３０の面積よりも大きくてよい。雌の犬の排尿口２０１Ｆは、背側領域ＲＲ３０に当たり易く、雄の犬の排尿口２０１Ｍは、腹側領域ＲＦ３０に当たりやすい。一方、猫の排尿口１０１は、雄の場合も雌の場合も、背側領域ＲＲ３０に当たり易い。猫のおむつにおいて、腹側領域ＲＦ３０の面積を大きくすることで、背側領域ＲＲ３０から腹側領域ＲＦ３０に拡散する体液保持することができる。また、一般的に、猫は飲水量が少ないため、泌尿器疾患にかかり易い。泌尿器疾患にかかると、多飲多尿の症状が出やすい。多尿になった場合は、吸収コア３０の腹側領域ＲＦ３０に拡散が広がる傾向がより顕著になる。腹側領域ＲＦ３０の面積を大きくすることで、多尿になった場合においても背側領域ＲＲ３０から腹側領域ＲＦ３０に拡散する体液保持することができる。 The absorption core 30 includes a ventral region RF30 located ventral to the center CZ30 in the vertical direction Z of the absorption core 30 and a dorsal region RR30 located dorsal to the center CZ30 in the vertical Z of the absorption core 30. Has. The area of the ventral region RF30 may be larger than the area of the dorsal region RR30. The urination port 201F of a female dog easily hits the dorsal region RR30, and the urination port 201M of a male dog easily hits the ventral region RF30. On the other hand, the cat urination port 101 easily hits the dorsal region RR30 in both males and females. In cat diapers, by increasing the area of the ventral region RF30, it is possible to retain the body fluid that diffuses from the dorsal region RR30 to the ventral region RF30. Also, in general, cats drink less water and are more susceptible to urinary diseases. Symptoms of polydipsia and polyuria are more likely to occur when suffering from urinary disorders. In the case of polyuria, the tendency for diffusion to spread to the ventral region RF30 of the absorption core 30 becomes more pronounced. By increasing the area of the ventral region RF30, it is possible to retain the body fluid that diffuses from the dorsal region RR30 to the ventral region RF30 even when polyuria occurs.

括れ部３１の内側縁３１Ｄにおける吸収コア３０の横方向Ｗの長さＷＤ３０は、背側領域ＲＲ３０における吸収コア３０の横方向の最大長さに対する８０％以下であってよい。括れ部３１の内側縁３１Ｄにおける吸収コア３０の横方向Ｗの長さＷＤ３０は、左右の内側縁３１Ｄ間の距離である。背側領域ＲＲ３０における吸収コア３０の横方向の最大長さは、本実施の形態においては、吸収コア３０の外側縁３０Ｅ間の距離である。吸収コア３０の背側領域ＲＲ３０における横方向Ｗの最大長さと、括れ部３１の内側縁３１Ｄにおける吸収コア３０の横方向Ｗの長さと、の差を大きく設けることができる。上述のように、猫の排尿口１０１は、雄の場合も雌の場合も、背側領域ＲＲ３０に当たり易い。猫のおむつにおいて、背側領域ＲＲ３０の吸収コア３０の横方向Ｗの最大長さを大きくすることで、背側領域ＲＲ３０の吸収容量を確保できる。加えて、猫は、犬と比較して、排尿口１０１と尻尾１０２の距離が短く、尻尾穴７０から体液が漏れやすい。背側領域ＲＲ３０の吸収コア３０の横方向Ｗの最大長さを大きくすることで、背側領域ＲＲ３０の吸収容量を確保し、尻尾穴７０からの体液の漏れを抑制できる。また、猫は、一般的に、犬と比較して体形の個体差が少なく、また脚幅が最も狭くなる部分１０５の脚幅が短い。括れ部３１の内側縁３１Ｄにおける吸収コア３０の横方向Ｗの長さＷＤ３０を短くすることで、脚幅が最も短くなる部分１０５に適切におむつフィットさせることができる。 The lateral W length WD30 of the absorption core 30 at the inner edge 31D of the constriction 31 may be 80% or less of the maximum lateral length of the absorption core 30 in the dorsal region RR30. The length WD30 of the absorption core 30 in the lateral direction W at the inner edge 31D of the constricted portion 31 is the distance between the left and right inner edges 31D. The maximum lateral length of the absorption core 30 in the dorsal region RR30 is, in the present embodiment, the distance between the outer edges 30E of the absorption core 30. A large difference can be provided between the maximum length of the lateral direction W in the dorsal region RR 30 of the absorption core 30 and the length of the lateral direction W of the absorption core 30 in the inner edge 31D of the constricted portion 31. As described above, the cat urination port 101 easily hits the dorsal region RR30 in both males and females. In cat diapers, the absorption capacity of the dorsal region RR30 can be secured by increasing the maximum length of the lateral W of the absorption core 30 of the dorsal region RR30. In addition, in cats, the distance between the urination port 101 and the tail 102 is shorter than that in dogs, and body fluid easily leaks from the tail hole 70. By increasing the maximum length of the absorption core 30 in the dorsal region RR30 in the lateral direction W, the absorption capacity of the dorsal region RR30 can be secured and the leakage of body fluid from the tail hole 70 can be suppressed. In addition, cats generally have less individual differences in body shape than dogs, and the leg width of the portion 105 having the narrowest leg width is short. By shortening the length WD30 of the absorption core 30 in the lateral direction W at the inner edge 31D of the constricted portion 31, the diaper can be appropriately fitted to the portion 105 having the shortest leg width.

図１に示すように、尻尾穴７０の横方向Ｗの最大長さＭ７０は、括れ部３１の内側縁３１Ｄにおける吸収コア３０の横方向Ｗの長さＷＤ３０以上であってよい。ここで、尻尾穴７０の横方向Ｗの最大長さＭ３０は、切り込み部７２を有する尻尾穴７０においては、穴本体部７１と切り込み部７２を合わせた領域の横方向Ｗの長さである。本実施の形態では、最も横方向Ｗの外側に位置する切り込み部７２の外側縁間の距離である。着用時に尻尾穴７０に尻尾１０２を挿入することで、尻尾を介して尻尾穴７０を横方向Ｗに引っ張ることができ、吸収コア３０には、横方向Ｗに伸長される力がかかる。吸収コア３０の横方向に広げて吸収コアのよれを低減でき、着用時における吸収コア３０の横方向Ｗの長さを確保し易い。特に猫は、犬と比較して、胴回り寸法に対する尻尾の径の比率が高い。よって、尻尾を介して吸収コア３０のよれを低減する効果を得やすい。尻尾穴７０の横方向Ｗの最大長さＭ７０が括れ部３１の吸収コア３０の横方向Ｗの長さＷＤ３０以上であるため、尻尾穴７０の横方向Ｗ全域に亘って吸収コア３０を広げる力が作用した際に、括れ部３１における吸収コア３０の横方向Ｗの全域を広げることができる。また、尻尾穴７０が括れ部３１の内側縁３１Ｄよりも横方向の外側に延出していることにより、横方向Ｗの外側から吸収コア３０を引っ張ることができ、吸収コア３０のよれをより抑制できる。 As shown in FIG. 1, the maximum length M70 of the tail hole 70 in the lateral direction W may be equal to or greater than the length WD30 of the absorption core 30 in the lateral direction W at the inner edge 31D of the constricted portion 31. Here, the maximum length M30 of the tail hole 70 in the lateral direction W is the length of the lateral direction W of the region where the hole main body portion 71 and the notch portion 72 are combined in the tail hole 70 having the notch portion 72. In the present embodiment, it is the distance between the outer edges of the notch 72 located on the outermost side of the lateral direction W. By inserting the tail 102 into the tail hole 70 at the time of wearing, the tail hole 70 can be pulled in the lateral direction W via the tail, and the absorption core 30 is subjected to a force extending in the lateral direction W. The absorption core 30 can be expanded in the lateral direction to reduce the twist of the absorption core, and it is easy to secure the length of the absorption core 30 in the lateral direction W when worn. In particular, cats have a higher ratio of tail diameter to waist circumference than dogs. Therefore, it is easy to obtain the effect of reducing the twist of the absorption core 30 via the tail. Since the maximum length M70 of the tail hole 70 in the lateral direction W is equal to or greater than the length WD30 of the absorption core 30 of the constriction portion 31 in the lateral direction W, the force for expanding the absorption core 30 over the entire lateral direction W of the tail hole 70. Can expand the entire lateral direction W of the absorption core 30 in the constricted portion 31 when Further, since the tail hole 70 extends outward in the lateral direction from the inner edge 31D of the constricted portion 31, the absorption core 30 can be pulled from the outside in the lateral direction W, and the twist of the absorption core 30 is further suppressed. can.

尻尾穴７０は、吸収コア３０の背側に位置する背外端縁Ｒ３０よりも背側に配置されてよい。すなわち、尻尾穴７０と吸収コア３０は、縦方向Ｚにおいて離間してよい。尻尾穴７０が吸収コア３０と重ならない領域に設けられているため、尻尾を介して尻尾穴７０を横方向Ｗに引っ張る力が吸収コア３０の剛性の影響を受けにくい。そのため、尻尾を介して吸収コア３０のよれを低減する効果をより得やすい。 The tail hole 70 may be arranged on the dorsal side of the dorsal outer edge R30 located on the dorsal side of the absorption core 30. That is, the tail hole 70 and the absorption core 30 may be separated from each other in the vertical direction Z. Since the tail hole 70 is provided in a region that does not overlap with the absorption core 30, the force that pulls the tail hole 70 laterally through the tail is not easily affected by the rigidity of the absorption core 30. Therefore, it is easier to obtain the effect of reducing the twist of the absorption core 30 via the tail.

平面視において括れ部３１と重なる領域には、コアラップ３２同士が重なる重畳部Ｒ３２（図１参照）が設けられてよい。重畳部Ｒ３２は、吸収コア３０が配置されてなく、コアラップ３２同士が当接する領域である。括れ部３１は、吸収コア３０が配置されてなく、吸収コア３０が配置された領域と比較して、その剛性を維持しにくいことがある。しかし、重畳部Ｒ３２にコアラップ３２を重ねて配置することで、括れ部３１近傍の剛性を高めることができる。吸収コア３０の括れ部３１のよれを抑制でき、フィット性を維持できる。 An overlapping portion R32 (see FIG. 1) in which the core wraps 32 overlap each other may be provided in a region that overlaps with the constricted portion 31 in a plan view. The overlapping portion R32 is a region where the absorption cores 30 are not arranged and the core wraps 32 are in contact with each other. The constricted portion 31 may be difficult to maintain its rigidity as compared with the region where the absorption core 30 is not arranged and the absorption core 30 is arranged. However, by arranging the core wrap 32 so as to overlap the overlapping portion R32, the rigidity in the vicinity of the constricted portion 31 can be increased. The constricted portion 31 of the absorption core 30 can be suppressed from twisting, and the fit can be maintained.

おむつを伸長させた伸長状態において、防漏ギャザー１５の固定部１７の横方向Ｗの内側縁１７Ｄは、括れ部３１の内側縁３１Ｄよりも横方向Ｗの外側に位置してよい。防漏ギャザー１５は、固定部１７を基点として起立部１６が立ち上がるとともに、吸収コア３０の剛性差によって吸収コア３０を基点に起立部１６及び固定部１７全体が立ち上がることがある。このとき、括れ部３１が設けられた領域において吸収コア３０の外側縁となる括れ部３１の内側縁３１Ｄよりも横方向Ｗの外側に固定部１７の内側縁１７Ｄがあるため、括れ部３１の内側縁を基点に起立部１６及び固定部１７全体が立ち上がる。括れ部３１が設けられた領域では、吸収コア３０の横方向Ｗの長さが比較的短く、吸収コアよりも横方向の外側に体液が導かれるおそれがあるが、起立部１６の立ち上がる高さを確保でき、漏れを抑制できる。 In the stretched state of the diaper, the inner edge 17D of the fixing portion 17 of the leak-proof gather 15 in the lateral direction W may be located outside the lateral direction W of the inner edge 31D of the constricted portion 31. In the leak-proof gather 15, the upright portion 16 may stand up from the fixed portion 17, and the upright portion 16 and the entire fixed portion 17 may stand up from the absorption core 30 due to the difference in rigidity of the absorption core 30. At this time, since the inner edge 17D of the fixing portion 17 is outside the inner edge 31D of the constricted portion 31 which is the outer edge of the absorption core 30 in the region where the constricted portion 31 is provided, the inner edge 17D of the fixing portion 17 is located outside the constricted portion 31. The standing portion 16 and the entire fixed portion 17 stand up from the inner edge as a base point. In the region where the constricted portion 31 is provided, the length of the lateral W of the absorption core 30 is relatively short, and the body fluid may be guided laterally to the outside of the absorption core. Can be secured and leakage can be suppressed.

The side edge 33 has a ventral edge F33 extending from the ventral base edge 311 to the medial edge 31D and a dorsal edge R33 extending from the dorsal base edge 312 to the medial edge 31D. The ventral edge F33 and the dorsal edge R33 are not symmetrical with respect to the lateral virtual line extending in the lateral direction W. The ventral edge F33 has a portion CF33 extending in a curve from the ventral base end edge 311 to the dorsal side, and a portion SF33 linearly connecting the curved portion CF33 and the inner edge 31D. The linearly extending portion SF33 is inclined at an angle α with respect to the vertical direction Z. The angle α is smaller than the inclination angle of the portion CF33 connected in a curved shape with respect to the vertical direction Z, and is an angle close to approximately 0 degrees (5 degrees or less). Further, in the ventral edge F33, the length of the portion SF33 extending linearly in the vertical direction Z is longer than the length of the portion CF33 connected in a curved shape in the vertical direction Z. Further, the dorsal edge R33 extends in a curved line from the dorsal base end edge 312 toward the inner edge 31D, and does not have a portion extending in a straight line.
