Further, the "other member" is a member other than the leak-proof cuff forming sheet 30 among the constituent members of the diaper 1, and typically, the sheet 30 is placed on the non-skin facing surface side of the sheet 30. It is a member arranged so as to be in contact with each other, and in the present embodiment, it is a surface sheet 21 as shown in FIG.

基端部31は、前述したとおり、防漏カフ形成用シート30と他の部材との固定部であり、典型的には、ホットメルト等の接着剤、熱融着等の公知の接合手段によって形成されている。本実施形態の基端部31は、図1に示すように、平面視において直線状をなし、防漏カフ形成用シート30の縦方向Xの略全長にわたって縦方向Xに延在し、また、図2に示すように、吸収体23の側縁23Sよりも横方向Yの外方で且つ該側縁23Sの近傍に位置している。基端部31の平面視形状は特に限定されず、直線の他、例えば、波線、湾曲線、ジグザグ線などでもよく、また、基端部31は一方向(縦方向X)に連続していなくてもよく、防漏カフ形成用シート30と他の部材との固定部と非固定部とが縦方向Xに交互に配置された構成の破断線でもよい。 As described above, the base end portion 31 is a fixing portion between the leak-proof cuff forming sheet 30 and other members, and is typically provided by an adhesive such as hot melt or a known joining means such as heat fusion. It is formed. As shown in FIG. 1, the base end portion 31 of the present embodiment has a linear shape in a plan view, extends in the vertical direction X over substantially the entire length of the leak-proof cuff forming sheet 30 in the vertical direction X, and also extends in the vertical direction X. As shown in FIG. 2, the absorber 23 is located outside the side edge 23S in the lateral direction and in the vicinity of the side edge 23S. The plan view shape of the base end portion 31 is not particularly limited, and may be, for example, a wavy line, a curved line, a zigzag line, or the like in addition to a straight line, and the base end portion 31 is not continuous in one direction (longitudinal direction X). It may be a break line having a structure in which fixed portions and non-fixed portions of the leak-proof cuff forming sheet 30 and other members are alternately arranged in the vertical direction X.

起立部32は、防漏カフ形成用シート30における他の部材との非固定部である。起立部32の防漏カフ形成用シート30は、図1及び図2に示すように、縦方向Xに延びる折り曲げ部33にて折り曲げられており、起立部32は、基端部31から折り曲げ部33にわたる第1起立部34と、折り曲げ部33から起立部32の自由端32aにわたり、第1起立部34よりも着用者の肌に近い側に位置する第2起立部35とを含んで構成されている。第2起立部35の表面は、おむつ1の着用時に着用者の肌と接触し得る。 The upright portion 32 is a non-fixed portion of the leak-proof cuff forming sheet 30 with other members. As shown in FIGS. 1 and 2, the leak-proof cuff forming sheet 30 of the upright portion 32 is bent by a bent portion 33 extending in the vertical direction X, and the upright portion 32 is bent from the base end portion 31. It is composed of a first standing portion 34 extending over 33 and a second standing portion 35 located from the bent portion 33 to the free end 32a of the standing portion 32 and located closer to the wearer's skin than the first standing portion 34. ing. The surface of the second upright portion 35 may come into contact with the wearer's skin when wearing the diaper 1.

本実施形態では図2に示すように、第1起立部34は、基端部31から折り曲げ部33に向かって横方向Yの内側に延び、第2起立部35は、折り曲げ部33から横方向Yの外側に延びている。折り曲げ部33は、起立部32においておむつ1の横方向Yの中央に最も近い部位であり、図1に示す如きおむつ1の展開且つ伸長状態において、縦方向Xに延びる直線状をなしている。一対の防漏カフ3,3どうしの離間部39は、一方の防漏カフ3の折り曲げ部33と他方の防漏カフ3の折り曲げ部33とに挟まれた領域である。 In the present embodiment, as shown in FIG. 2, the first standing portion 34 extends inward in the lateral direction Y from the base end portion 31 toward the bent portion 33, and the second standing portion 35 extends laterally from the bent portion 33. It extends to the outside of Y. The bent portion 33 is a portion of the upright portion 32 that is closest to the center of the diaper 1 in the lateral direction Y, and has a linear shape extending in the vertical direction X in the unfolded and extended state of the diaper 1 as shown in FIG. The separation portion 39 between the pair of leak-proof cuffs 3 and 3 is a region sandwiched between the bent portion 33 of one leak-proof cuff 3 and the bent portion 33 of the other leak-proof cuff 3.

本発明において、おむつ1(吸収性物品)の「展開且つ伸長状態」とは、おむつ1を図1に示す如き展開状態とし、その展開状態のおむつ1を各部の弾性部材を伸長させて設計寸法(弾性部材の影響を一切排除した状態で平面状に広げたときの寸法と同じ)となるまで拡げた状態をいう。 In the present invention, the "expanded and stretched state" of the diaper 1 (absorbent article) means that the diaper 1 is in the unfolded state as shown in FIG. (Same as the dimensions when expanded in a plane with the influence of the elastic member completely removed).

本実施形態においては、図1及び図2に示すように、第2起立部35に防漏カフ形成用弾性部材36が縦方向Xに伸縮可能な状態で配されている。第2起立部35における、防漏カフ形成用弾性部材36が縦方向Xに伸縮可能な状態で配されている部分は、縦方向Xに伸縮性を有している。より具体的には、第2起立部35は図2に示すように、防漏カフ形成用シート30が横方向Yに二つに折られて二層構造となった部分を含んで構成され、該二層構造を構成する2枚の該シート30,30間に、糸状の複数(4本)の防漏カフ形成用弾性部材36が伸長状態で横方向Yに並べて固定されており、これにより各弾性部材36が縦方向Xに伸縮可能な状態で配されている。起立部32の自由端32aは、この防漏カフ形成用シート30における二つ折りの折り目に位置している。防漏カフ形成用弾性部材36は糸状が好ましいが、これに変えて帯状であってもよい。また、本実施形態においては、各第2起立部35に防漏カフ形成用弾性部材36が4本配されているが、該弾性部材36の数は特に制限されず、1本でもよい。 In the present embodiment, as shown in FIGS. 1 and 2, an elastic member 36 for forming a leak-proof cuff is arranged on the second standing portion 35 in a state where it can be expanded and contracted in the vertical direction X. The portion of the second standing portion 35 in which the elastic member 36 for forming a leak-proof cuff is arranged so as to be stretchable in the vertical direction X has elasticity in the vertical direction X. More specifically, as shown in FIG. 2, the second upright portion 35 is configured to include a portion in which the leak-proof cuff forming sheet 30 is folded in two in the lateral direction Y to form a two-layer structure. A plurality of (4) thread-like elastic members for forming leak-proof cuffs 36 are fixed side by side in the lateral direction Y in an extended state between the two sheets 30 and 30 constituting the two-layer structure. Each elastic member 36 is arranged in a state where it can be expanded and contracted in the vertical direction X. The free end 32a of the upright portion 32 is located at the fold in half in the leak-proof cuff forming sheet 30. The elastic member 36 for forming the leak-proof cuff is preferably thread-shaped, but may be strip-shaped instead. Further, in the present embodiment, four elastic members 36 for forming a leak-proof cuff are arranged in each of the second standing portions 35, but the number of the elastic members 36 is not particularly limited and may be one.

防漏カフ3は、典型的には、防漏カフ形成用シート30に対して防漏カフ形成用弾性部材36を伸長状態で固定した後にその伸長状態を解放することによって作製されているところ、斯かる作製方法に起因して、おむつ1の着用者の肌と接触し得る第2起立部35の表面に多数の皺が存在する。この第2起立部35の表面の皴は、縦方向Xに略規則的に間欠配置されている。 The leak-proof cuff 3 is typically manufactured by fixing the leak-proof cuff-forming elastic member 36 to the leak-proof cuff-forming sheet 30 in an stretched state and then releasing the stretched state. Due to such a manufacturing method, there are many wrinkles on the surface of the second upright portion 35 which can come into contact with the skin of the wearer of the diaper 1. The wrinkles on the surface of the second standing portion 35 are arranged substantially regularly in the vertical direction X.

起立部32は、少なくとも股下部Mに存在することが好ましい。おむつ1において排泄物が集中し横漏れが特に問題となる部位は股下部Mであるためである。本実施形態の起立部32は、図1に示すように、股下部Mの縦方向Xの全長にわたり、更に腹側部F及び背側部Rの双方に延出している。 The upright portion 32 is preferably present at least in the inseam M. This is because the part of the diaper 1 where excrement is concentrated and lateral leakage is particularly problematic is the inseam M. As shown in FIG. 1, the standing portion 32 of the present embodiment extends over the entire length of the crotch portion M in the longitudinal direction X, and further extends to both the ventral side portion F and the dorsal side portion R.

図1に示すように、一対の防漏カフ3,3それぞれの起立部32の縦方向Xの両外方には起立阻害部37が形成されている。起立部32は、縦方向Xの一端側(腹側部F側)の起立阻害部37と他端側(背側部R側)の起立阻害部37とに挟まれている。起立阻害部37では、防漏カフ形成用シート30における起立部32(すなわち他の部材との非固定部)と横方向Yにおいて同位置に存在する部分が、平面視で吸収体23と重なる位置にて他の部材(本実施形態においては表面シート21)に固定されており、これにより、起立部32が起立しても、起立阻害部38は起立しないようになされている。 As shown in FIG. 1, standing inhibition portions 37 are formed on both outer sides of the standing portions 32 of each of the pair of leakage-proof cuffs 3 and 3 in the vertical direction X. The upright portion 32 is sandwiched between an upright inhibition portion 37 on one end side (ventral side F side) and an upright inhibition portion 37 on the other end side (dorsal side R side) in the longitudinal direction X. In the standing inhibition portion 37, a portion of the leak-proof cuff forming sheet 30 that exists at the same position as the standing portion 32 (that is, a non-fixed portion with another member) in the lateral direction Y overlaps with the absorber 23 in a plan view. Is fixed to another member (the surface sheet 21 in the present embodiment), so that the standing portion 38 does not stand even if the standing portion 32 stands up.

おむつ1の着用時には、一対の防漏カフ3,3それぞれの起立部32(第1起立部34及び第2起立部35)が、第2起立部35に配された防漏カフ形成用弾性部材36の収縮力により、基端部31を起立基端として起立し(図3参照)、これにより、少なくとも股下部Mにおける吸収性本体2の肌対向面の縦方向Xに沿う両側部に、起立部32からなる防漏壁が一対形成される。この一対の防漏壁は、おむつ1の肌対向面に排泄された尿や便等の排泄物を堰き止め、排泄物がおむつ1の横方向Yの外方に漏れ出す、いわゆる横漏れを防止する。 When the diaper 1 is worn, the standing portions 32 (first standing portion 34 and second standing portion 35) of each of the pair of leak-proof cuffs 3 and 3 are arranged in the second standing portion 35 to form an elastic member for forming a leak-proof cuff. Due to the contraction force of 36, the base end portion 31 stands up with the base end portion 31 as the standing base end (see FIG. 3), whereby at least on both sides of the absorbent body 2 in the inseam M along the vertical direction X of the skin-facing surface. A pair of leak-proof walls composed of the portions 32 are formed. This pair of leak-proof walls blocks excrement such as urine and feces excreted on the skin-facing surface of the diaper 1 and prevents the excrement from leaking to the outside of the diaper 1 in the lateral direction Y, so-called lateral leakage. To do.

また、おむつ1の着用時には、防漏カフ形成用弾性部材36の収縮力により、該弾性部材36の配置部であるおむつ1の縦方向Xの中央部(股下部Mを含む部分)が、非肌対向面側(裏面シート22側)に凸となるように、換言すれば肌対向面側(表面シート21側)に凹となるように、おむつ1が湾曲する。こうしておむつ1は全体として舟形形状に変形する。このような舟形形状のおむつ1は着用者の股間部の形状に沿いやすいため、該おむつ1における起立状態の起立部32の第2起立部35は、着用者の肌にフィット性良く密着し、これにより防漏カフ3による横漏れ防止機能が効果的に発現し得る。 Further, when the diaper 1 is worn, the central portion (the portion including the inseam M) of the diaper 1 which is the arrangement portion of the elastic member 36 is not formed due to the contraction force of the elastic member 36 for forming the leak-proof cuff. The diaper 1 is curved so as to be convex on the skin-facing surface side (back surface sheet 22 side), in other words, concave on the skin-facing surface side (front surface sheet 21 side). In this way, the diaper 1 is transformed into a boat shape as a whole. Since such a boat-shaped diaper 1 easily follows the shape of the crotch portion of the wearer, the second standing portion 35 of the standing portion 32 in the standing state of the diaper 1 fits well to the wearer's skin and adheres to the skin. As a result, the lateral leakage prevention function of the leakage prevention cuff 3 can be effectively exhibited.

おむつ1の主たる特徴の1つとして、図1に示す如きおむつ1の展開且つ伸長状態において、おむつ1を横方向Yに横断する1本の仮想直線VLを引いた場合に、該仮想直線VLにおける一対の防漏カフ3,3それぞれの第2起立部35と重複する部分の長さ35L(図2参照)の合計が、該仮想直線VLにおける離間部39と重複する部分の長さ39L(図2参照)の20%以上50%以下である「特定部分」を有する点が挙げられる。なお、長さ35L、39Lは前記のとおり、横方向Yに延びる仮想直線VLにおける所定部分(第2起立部35又は離間部39と重複する部分)の長さであり、すなわち、第2起立部35又は離間部39の平面視での横方向Yの長さ、換言すれば、第2起立部35又は離間部39をおむつ1(吸収体23)の厚み方向に投影した場合の投影像の横方向Yの長さである。 As one of the main features of the diaper 1, when one virtual straight line VL that crosses the diaper 1 in the lateral direction Y is drawn in the expanded and extended state of the diaper 1 as shown in FIG. The total length of the portion overlapping the second standing portion 35 of each of the pair of leak-proof cuffs 3 and 3 (see FIG. 2) is 39 L (see FIG. 2). 2), which has a "specific portion" of 20% or more and 50% or less. As described above, the lengths 35L and 39L are the lengths of predetermined portions (parts overlapping the second standing portion 35 or the separating portion 39) in the virtual straight line VL extending in the lateral direction Y, that is, the second standing portion. The length of the lateral portion Y in the plan view of the 35 or the separation portion 39, in other words, the lateral direction of the projected image when the second standing portion 35 or the separation portion 39 is projected in the thickness direction of the diaper 1 (absorbent body 23). The length of the direction Y.

このように、おむつ1の展開且つ伸長状態において、一対の第2起立部35,35それぞれの平面視での横方向Yの長さ35Lの合計(35L+35L)と該一対の第2起立部35,35に挟まれた離間部39の平面視での横方向Yの長さ39Lとの比率(以下、「第2起立部/離間部比率」ともいう。)が、20%以上50%以下の範囲にあることにより、防漏カフ3が漏れ防止性能に優れたものとなり、横漏れが効果的に防止され得る。第2起立部/離間部比率が20%未満では、起立状態の起立部32の上部(着用者の肌に最も近い部分)を構成する第2起立部35の防漏機能すなわち尿や便などの排泄物のブロック機能が低下し、排泄物が起立状態の防漏カフ3(起立部32)を乗り越えて横方向Yの外方に漏れ出すおそれがある。また、第2起立部/離間部比率が50%を超えると、第2起立部35が、その横方向Yの外方に位置するおむつ1(サイドフラップ部4)の縦方向Xに沿う側縁に近づきすぎたり、該側縁を超えておむつ1の外方にはみ出たりする場合があり、その結果、防漏カフ3による防漏作用が十分に発揮されない、防漏カフ3の外観が悪化するなどの不都合が生じるおそれがある。また、本実施形態では前述したとおり、サイドフラップ部4にレッグカフ41が設けられているところ、第2起立部/離間部比率が50%を超えると、第2起立部35がレッグカフ41(レッグカフ形成用弾性部材42)と重なりやすくなり、その結果、レッグカフ41のフィット性が低下する、着用者の肌トラブルを招くなどの不都合が生じるおそれがある。後者の肌トラブルは、縦方向Xに伸縮性を有する第2起立部35と同方向に伸縮性を有するレッグカフ41とが重なることによって、それらの重なり部が着用者の脚周りをきつく締める結果として起こり得るものである。第2起立部/離間部比率は、好ましくは25%以上47.5%以下、より好ましくは30%以上45%以下である。 As described above, in the unfolded and extended state of the diaper 1, the total (35L + 35L) of the length 35L in the lateral direction Y in the plan view of each of the pair of the second standing portions 35, 35 and the pair of the second standing portions 35, The ratio of the separation portion 39 sandwiched between the 35 to the length 39L in the lateral direction in the plan view (hereinafter, also referred to as “second standing portion / separation portion ratio”) is in the range of 20% or more and 50% or less. Therefore, the leakage-proof cuff 3 has excellent leakage prevention performance, and lateral leakage can be effectively prevented. When the ratio of the second standing portion / separated portion is less than 20%, the leak-proof function of the second standing portion 35 constituting the upper part of the standing portion 32 in the standing state (the portion closest to the wearer's skin), that is, urine, feces, etc. The blocking function of excrement may be reduced, and the excrement may leak to the outside in the lateral direction Y over the leak-proof cuff 3 (standing portion 32) in the standing state. When the ratio of the second standing portion / separated portion exceeds 50%, the second standing portion 35 has a side edge along the vertical direction X of the diaper 1 (side flap portion 4) located outside the lateral direction Y. The diaper may be too close to the diaper or may protrude to the outside of the diaper 1 beyond the side edge, and as a result, the leak-proof effect of the leak-proof cuff 3 is not sufficiently exerted, and the appearance of the leak-proof cuff 3 is deteriorated. There is a risk of inconvenience such as. Further, in the present embodiment, as described above, when the leg cuff 41 is provided on the side flap portion 4, when the ratio of the second standing portion / separated portion exceeds 50%, the second standing portion 35 becomes the leg cuff 41 (leg cuff forming). It tends to overlap with the elastic member 42), and as a result, the fit of the leg cuff 41 may be deteriorated, and inconveniences such as causing skin troubles of the wearer may occur. The latter skin trouble is caused by the overlap of the second standing portion 35 having elasticity in the vertical direction X and the leg cuff 41 having elasticity in the same direction, and the overlapping portion tightens the wearer's leg circumference. It can happen. The ratio of the second standing portion / separated portion is preferably 25% or more and 47.5% or less, and more preferably 30% or more and 45% or less.

第2起立部/離間部比率が前記特定範囲にあることによる作用効果をより一層確実に奏させるようにする観点から、おむつ1の各部の寸法等は以下のように設定することが好ましい。
おむつ1の展開且つ伸長状態における仮想直線VLの第2起立部35と重複する部分の長さ35L(図2参照)、すなわち第2起立部35の平面視での横方向Yの長さ35Lは、好ましくは7.5mm以上、より好ましくは10mm以上、そして、好ましくは17.5mm以下、より好ましくは15mm以下である。なお、一対の防漏カフ3,3うちの一方の第2起立部35についての長さ35Lと他方のそれとは、典型的には同じであるが、異なっていてもよい。
おむつ1の展開且つ伸長状態における仮想直線VLの離間部39と重複する部分の長さ39L(図2参照)、すなわち離間部39の平面視での横方向Yの長さ39Lは、好ましくは60mm以上、より好ましくは70mm以上、そして、好ましくは90mm以下、より好ましくは80mm以下である。なお、本実施形態のおむつ1では、長さ39Lは、離間部39の縦方向Xの全長にわたって一定であるが、本発明では縦方向Xにおいて一定でなくてもよく、その場合、長さ39Lは前記の好ましい範囲内で縦方向Xにおいて変化することが好ましい。
It is preferable to set the dimensions and the like of each part of the diaper 1 as follows from the viewpoint of ensuring that the action and effect due to the ratio of the second standing part / separated part being in the specific range are more reliably exerted.
The length 35L of the portion overlapping the second standing portion 35 of the virtual straight line VL in the unfolded and extended state of the diaper 1 (see FIG. 2), that is, the length 35L of the second standing portion 35 in the horizontal direction Y in the plan view is It is preferably 7.5 mm or more, more preferably 10 mm or more, and preferably 17.5 mm or less, more preferably 15 mm or less. The length 35L of one of the pair of leakage-proof cuffs 3 and 3 for the second standing portion 35 and that of the other are typically the same, but may be different.
The length 39L of the portion overlapping the separation portion 39 of the virtual straight line VL in the unfolded and extended state of the diaper 1 (see FIG. 2), that is, the length 39L of the separation portion 39 in the horizontal direction Y in the plan view is preferably 60 mm. As mentioned above, it is more preferably 70 mm or more, preferably 90 mm or less, and more preferably 80 mm or less. In the diaper 1 of the present embodiment, the length 39L is constant over the entire length of the separation portion 39 in the vertical direction X, but in the present invention, it does not have to be constant in the vertical direction X, in which case the length 39L. Is preferably changed in the vertical direction X within the above-mentioned preferable range.

前記特定部分、すなわち第2起立部/離間部比率が20%以上50%以下の範囲にある部分は、少なくとも股下部Mに存在することが好ましい。股下部Mが最も横漏れが懸念される部位であるためである。最も好ましい形態は、一対の防漏カフ3,3(一対の起立部32,32)を横方向Yに横断する任意の1本の仮想直線VLを引いた場合に、第2起立部/離間部比率が20%以上50%以下の範囲にある形態である。すなわち、一対の防漏カフ3,3(一対の起立部32,32)及びそれらに挟まれた離間部39の全体が前記特定部分であることが最も好ましい。 The specific portion, that is, a portion in which the ratio of the second standing portion / separated portion is in the range of 20% or more and 50% or less is preferably present in at least the inseam M. This is because the inseam M is the site where lateral leakage is most a concern. The most preferable form is a second standing portion / separating portion when an arbitrary one virtual straight line VL that crosses the pair of leakage-proof cuffs 3, 3 (a pair of standing portions 32, 32) in the lateral direction Y is drawn. It is a form in which the ratio is in the range of 20% or more and 50% or less. That is, it is most preferable that the entire pair of leakage-proof cuffs 3, 3 (pair of standing portions 32, 32) and the separating portion 39 sandwiched between them are the specific portions.

前記特定部分では、おむつ1の展開且つ伸長状態において、おむつ1を横方向Yに横断する1本の仮想直線VL(図1参照)を引いた場合に、「該仮想直線VLにおける第1起立部34と重複する部分の長さ34L(図4参照)の合計」、換言すれば、「一対の防漏カフ3,3それぞれの該仮想直線VLと重複する第1起立部34の横方向Yの長さ34Lの合計」が、「該仮想直線VLにおける離間部39と重複する部分の長さ39L(図2参照)」の55%以上100%以下であることが好ましい。 In the specific portion, when one virtual straight line VL (see FIG. 1) crossing the diaper 1 in the lateral direction Y is drawn in the expanded and extended state of the diaper 1, "the first standing portion in the virtual straight line VL" is drawn. The total length of the portion overlapping with 34 (see FIG. 4), in other words, "the lateral direction Y of the first standing portion 34 overlapping with the virtual straight line VL of each of the pair of leakage-proof cuffs 3, 3". It is preferable that the "total length 34L" is 55% or more and 100% or less of the "length 39L of the portion overlapping the separation portion 39 in the virtual straight line VL (see FIG. 2)".

なお、長さ34Lは、図4(a)に示すように、第1起立部34の実際の横方向Yの長さ、すなわち、基端部31から折り曲げ部33にわたる部分を設計寸法まで伸ばした状態での横方向Yの長さであり、長さ39Lのような、対象(第1起立部34)の平面視での長さではなく、第1起立部34の平面視での横方向Yの長さとは必ずしも一致しない。本発明には、図4(b)に示す如き、基端部31が吸収体23と平面視で重なる位置に存在する形態が包含され、斯かる形態では、防漏カフ形成用シート30における平面視で吸収体23と重なる部分の全体が基端部31であるところ、斯かる形態における第1起立部34の横方向Yの長さ34Lの意味するところも前記と同様である。また図4には、後述する起立部32全体(基端部31から折り曲げ部33を介して自由端32aにわたる部分)の横方向Yの長さ32Lが示されているところ、この長さ32Lの意味するところも前記と同様に、起立部32の実際の横方向Yの長さである。 As shown in FIG. 4A, the length 34L is the actual length of the first standing portion 34 in the lateral direction Y, that is, the portion extending from the base end portion 31 to the bent portion 33 is extended to the design dimension. It is the length of the lateral direction Y in the state, not the length of the object (first standing portion 34) in the plan view as in the length 39L, but the lateral direction Y of the first standing portion 34 in the plan view. Does not always match the length of. The present invention includes a form in which the base end portion 31 is present at a position where the base end portion 31 overlaps the absorber 23 in a plan view as shown in FIG. 4 (b). Where the entire portion overlapping the absorber 23 visually is the base end portion 31, the meaning of the lateral Y length 34L of the first standing portion 34 in such a form is the same as described above. Further, FIG. 4 shows a length 32L in the lateral direction of the entire standing portion 32 (a portion extending from the base end portion 31 to the free end 32a via the bent portion 33), which will be described later. The meaning is also the actual length of the upright portion 32 in the lateral direction Y, as described above.

このように、おむつ1の展開且つ伸長状態において、一対の第1起立部34,34それぞれの横方向Yの長さ34Lの合計(34L+34L)と該一対の第1起立部34,34に挟まれた離間部39の平面視での横方向Yの長さ39Lとの比率(以下、「第1起立部/離間部比率」ともいう。)が、55%以上100%以下の範囲にあることにより、起立状態の防漏カフ3(起立部32)の起立高さが十分なものとなるため、第2起立部/離間部比率が前記特定範囲にあることと相俟って、横漏れがより一層効果的に防止され得る。第1起立部/離間部比率は、好ましくは60%以上95%以下、より好ましくは65%以上90%以下である。 In this way, in the unfolded and extended state of the diaper 1, it is sandwiched between the total (34L + 34L) of the lateral Y lengths 34L of each of the pair of first standing portions 34, 34 and the pair of first standing portions 34, 34. The ratio of the separated portion 39 to the length 39L in the lateral direction in the plan view (hereinafter, also referred to as “first standing portion / separated portion ratio”) is in the range of 55% or more and 100% or less. Since the standing height of the leak-proof cuff 3 (standing portion 32) in the standing state is sufficient, lateral leakage is more likely to occur in combination with the fact that the ratio of the second standing portion / separated portion is within the above-mentioned specific range. It can be prevented more effectively. The ratio of the first standing portion / separated portion is preferably 60% or more and 95% or less, and more preferably 65% or more and 90% or less.

第1起立部/離間部比率が前記特定範囲にあることによる作用効果をより一層確実に奏させるようにする観点から、おむつ1の展開且つ伸長状態における第1起立部34の横方向Yの長さ34L(図4参照)は、好ましくは20mm以上、より好ましくは25mm以上、そして、好ましくは40mm以下、より好ましくは35mm以下である。なお、一対の防漏カフ3,3うちの一方の第1起立部34についての長さ34Lと他方のそれとは、典型的には同じであるが、異なっていてもよい。離間部39の平面視での横方向Yの長さ39Lの好ましい範囲については前述したとおりである。 The length of the first standing portion 34 in the lateral direction Y in the unfolded and extended state of the diaper 1 from the viewpoint of ensuring that the action and effect of the first standing portion / separated portion ratio being in the specific range are more reliably exerted. 34L (see FIG. 4) is preferably 20 mm or more, more preferably 25 mm or more, and preferably 40 mm or less, more preferably 35 mm or less. The length 34L of one of the pair of leakage-proof cuffs 3 and 3 for the first standing portion 34 and that of the other are typically the same, but may be different. The preferable range of the length 39L in the lateral direction Y in the plan view of the separating portion 39 is as described above.

前記特定部分では、おむつ1の展開且つ伸長状態において、おむつ1を横方向Yに横断する1本の仮想直線VL(図1参照)を引いた場合に、「該仮想直線VLと重複する第1起立部34の横方向Yの長さ34L(図4参照)」が、「該仮想直線VLにおける、第1起立部34に隣接する基端部31から横方向Yの外方に位置するおむつ1の縦方向Xに沿う側縁1S(図1参照)にわたる部分と重複する部分の長さ31L(図2参照)」よりも短いことが好ましい。なお、長さ31Lは前記のとおり、横方向Yに延びる仮想直線VLにおける所定部分(第1起立部34に隣接する基端部31からその横方向Yの外方に位置するおむつ1の側縁1Sにわたる部分)の長さであり、すなわち、該所定部分の平面視での横方向Yの長さ、換言すれば、該所定部分をおむつ1(吸収体23)の厚み方向に投影した場合の投影像の横方向Yの長さである。また、前記の「基端部31からその横方向Yの外方に位置するおむつ1の側縁1Sにわたる部分」は、要は、第1起立部34よりも横方向Yの外方に位置する部分であり、本実施形態ではサイドフラップ部4である。 In the specific portion, when one virtual straight line VL (see FIG. 1) crossing the diaper 1 in the lateral direction Y is drawn in the expanded and extended state of the diaper 1, "the first overlapping with the virtual straight line VL". The length 34L of the upright portion 34 in the lateral direction Y (see FIG. 4) is "a diaper 1 located outside the lateral direction Y from the base end portion 31 adjacent to the first upright portion 34 in the virtual straight line VL". It is preferable that the length of the portion overlapping the portion extending over the side edge 1S (see FIG. 1) along the vertical direction X is 31 L (see FIG. 2). As described above, the length 31L is a predetermined portion in the virtual straight line VL extending in the lateral direction Y (the side edge of the diaper 1 located outside the base end portion 31 adjacent to the first standing portion 34 in the lateral direction Y). The length of (a portion extending over 1S), that is, the length of the predetermined portion in the lateral direction Y in a plan view, in other words, when the predetermined portion is projected in the thickness direction of the diaper 1 (absorbent 23). It is the length of the projected image in the horizontal direction Y. Further, the above-mentioned "portion extending from the base end portion 31 to the side edge 1S of the diaper 1 located outside the lateral direction Y" is basically located outside the lateral direction Y with respect to the first standing portion 34. It is a portion, and in the present embodiment, it is a side flap portion 4.

By establishing the magnitude relationship of "the length 31L in the lateral direction Y", the inconvenience that the leakage-proof cuff 3, particularly the second standing portion 35, protrudes from the side edge of the diaper 1 is prevented. If the leak-proof cuff 3 (second standing portion 35) protrudes from the side edge of the diaper 1, the leak-proof cuff 3 may not sufficiently exert the leak-proof effect, and the appearance of the leak-proof cuff 3 may be deteriorated. There is. Further, when the leg cuff 41 is provided on the side flap portion 4 as in the present embodiment, the chance that the second standing portion 35 overlaps with the leg cuff 41 increases, so that the performance of the leg cuff 41 deteriorates. May lead to.

以下、本発明を実施例により更に具体的に説明するが、本発明は斯かる実施例に限定されるものではない。 Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited to such Examples.

〔実施例1〜5、比較例1〜2、参考例1〜3〕
図1に示すおむつ1と基本構成が同様の展開型使い捨ておむつを作製した。具体的には、展開型使い捨ておむつとして、花王株式会社製のメリーズテープタイプSサイズ(2017年製、登録商標)を用意し、その用意したおむつの防漏カフの各部の寸法等を適宜調整して、実施例、比較例及び参考例の展開型使い捨ておむつを作製した。
[Examples 1 to 5, Comparative Examples 1 to 2, Reference Examples 1 to 3]
A deployable disposable diaper having the same basic configuration as the diaper 1 shown in FIG. 1 was produced. Specifically, as a deployable disposable diaper, we prepared a Mary's tape type S size (made in 2017, registered trademark) manufactured by Kao Corporation, and adjusted the dimensions of each part of the leak-proof cuff of the prepared diaper as appropriate. The deployable disposable diapers of Examples, Comparative Examples, and Reference Examples were prepared.

実施例、比較例及び参考例の使い捨ておむつについて、下記方法により、防漏カフの横漏れ防止性及びはみ出しやすさをそれぞれ評価した。その結果を下記表1に示す。 The disposable diapers of Examples, Comparative Examples, and Reference Examples were evaluated for lateral leakage prevention and easiness of protrusion of the leakage-proof cuff by the following methods. The results are shown in Table 1 below.

<防漏カフの横漏れ防止性の評価方法>
排泄ポイントを設けたモデル人形に評価対象のおむつをはかせ、下記方法により、該おむつの防漏カフの横漏れ防止性を評価した。まず、おむつを前記モデル人形に装着し、横向きとなるようにモデル人形を90°傾けた。この状態でおむつにおける前記排泄ポイントに対応する部位に疑似軟便10gを注入した。擬似軟便の組成は、ベントナイト22.5質量%、界面活性剤(ポイズ530、固形分40質量%、花王株式会社製)0.5質量%、エマルゲン130K0.03質量%水溶液(花王株式会社製)1.5質量%、イオン交換水75.5質量%であり、粘度は40mPa・s(23℃、振動式粘度計:株式会社エー・アンド・デイ製、SV−10)、表面張力は55mN/mであった。擬似軟便の注入後、速やかに、モデル人形を直立状態にし、モデル人形の股下に位置するおむつをモデル人形側に3kPaの圧力で圧迫した時に、疑似軟便がおむつの防漏カフより横方向外側に漏れるか否かを観察した。以上の操作を1個の評価対象につき10回行い、横漏れを防止できた確率(全10回に占める、擬似軟便の漏れが観察されなかった回数の割合)を横漏れ防止性とした。この数値が大きいほど、防漏カフの横漏れ防止性に優れ、高評価となる。この数値が70%以上の場合を合格とした。
<Evaluation method for lateral leakage prevention of leak-proof cuffs>
The model doll provided with the excretion point was put on the diaper to be evaluated, and the lateral leakage prevention property of the leakage-proof cuff of the diaper was evaluated by the following method. First, the diaper was attached to the model doll, and the model doll was tilted 90 ° so as to be turned sideways. In this state, 10 g of pseudo loose stool was injected into the site corresponding to the excretion point in the diaper. The composition of the pseudo loose stool is 22.5% by mass of bentonite, 0.5% by mass of a surfactant (poise 530, solid content 40% by mass, manufactured by Kao Co., Ltd.), and an aqueous solution of Emargen 130K 0.03% by mass (manufactured by Kao Co., Ltd.). 1.5% by mass, ion-exchanged water 75.5% by mass, viscosity 40 mPa · s (23 ° C, vibration viscometer: A & D Co., Ltd., SV-10), surface tension 55 mN / It was m. Immediately after injecting the pseudo loose stool, the model doll is placed upright, and when the diaper located in the inseam of the model doll is pressed against the model doll with a pressure of 3 kPa, the pseudo loose stool laterally outwards from the leak-proof cuff of the diaper. It was observed whether or not it leaked. The above operation was performed 10 times for each evaluation target, and the probability that lateral leakage could be prevented (the ratio of the number of times that pseudo loose stool leakage was not observed to the total of 10 times) was defined as the lateral leakage prevention property. The larger this value is, the better the lateral leakage prevention property of the leakage prevention cuff is, and the higher the evaluation is. A case where this value was 70% or more was regarded as a pass.

<防漏カフのはみ出しやすさの評価方法>
モデル人形に評価対象のおむつをはかせ、該おむつの防漏カフが該おむつの縦方向に沿う側縁から横方向外方にはみ出しているか否かを観察した。以上の操作を1個の評価対象につき10回行い、防漏カフがはみ出した確率(全10回に占める、防漏カフのはみ出しが確認できた回数の割合)を防漏カフのはみ出しやすさとした。この数値が小さいほど、防漏カフがおむつの側縁から横方向外方にはみ出しにくく、高評価となる。この数値が0%以下の場合を合格とした。
<Evaluation method for ease of protrusion of leak-proof cuff>
The model doll was put on the diaper to be evaluated, and it was observed whether or not the leak-proof cuff of the diaper protruded laterally outward from the side edge along the vertical direction of the diaper. The above operation was performed 10 times for each evaluation target, and the probability that the leak-proof cuff squeezed out (the ratio of the number of times the leak-proof cuff squeezed out to the total of 10 times) was determined to be the easiness of the leak-proof cuff sticking out. .. The smaller this value is, the more difficult it is for the leak-proof cuff to protrude laterally outward from the side edge of the diaper, and the higher the evaluation. A case where this value was 0% or less was regarded as a pass.

Figure 2021069863

表1に示すとおり、各実施例は、第2起立部/離間部比率が20%以上50%以下の範囲にあるため、これを満たさない各比較例に比べて、防漏カフの横漏れ防止性に優れ、且つ防漏カフがおむつの側縁を超えて外方にはみ出しにくいものであった。
参考例1〜2は、第2起立部/離間部比率が20%以上50%以下の範囲にあるものの、第1起立部/離間部比率が55%以上100%以下の範囲から外れているため、各実施例に比べて評価に劣る結果となった。
参考例3は、「34L/31L」及び「32L/31L」の双方が1以上であるため、防漏カフがおむつの側縁を超えて外方にはみ出しやすい結果となった。
As shown in Table 1, since the second standing portion / separation portion ratio is in the range of 20% or more and 50% or less in each example, lateral leakage prevention of the leak-proof cuff is compared with each comparative example which does not satisfy this. It had excellent properties, and the leak-proof cuff did not easily protrude outward beyond the side edges of the diaper.
In Reference Examples 1 and 2, the second standing portion / separation portion ratio is in the range of 20% or more and 50% or less, but the first standing portion / separation portion ratio is out of the range of 55% or more and 100% or less. , The result was inferior to each example.
In Reference Example 3, since both “34L / 31L” and “32L / 31L” were 1 or more, the result was that the leak-proof cuff easily protruded beyond the side edge of the diaper.
