本明細書において、「縦方向Ｘ上方」とは、ウエスト開口部１Ｗの開口端５０に近付く方向を意味し、「縦方向Ｘ下方」とは、後述する股下領域Ｃの縦方向Ｘ中間部に近付く方向を意味する。つまり、「縦方向Ｘ上方」及び「縦方向Ｘ下方」は、着用状態における着用者の上下方向に対応する。
本明細書では、厚み方向Ｚに関しては、着用時に着用者の肌に近い側を肌側、着衣に近い側を非肌側という事がある。また、「肌対向面」とは、おむつ１又はその構成部材における、おむつ１の着用時に着用者の肌側に向けられる面、すなわち相対的に着用者の肌に近い面を意味する。「非肌対向面」とは、おむつ１又はその構成部材における、おむつ１の着用時に肌側とは反対側（着衣側）に向けられる面、すなわち相対的に着用者の肌から遠い面を意味する。
「着用時」は、通常想定される適正な着用位置が維持された状態をいう。 As shown in FIG. 1, the diaper 1 includes a waist opening 1W and a pair of leg openings IL, and is worn on the wearer's lower abdomen and crotch when worn. The waist opening 1W has an opening end 50. The diaper 1 has a vertical direction X, a horizontal direction Y, and a thickness direction Z. The longitudinal direction X extends from the ventral side of the wearer through the crotch to the dorsal side. The horizontal direction Y is orthogonal to the vertical direction X and corresponds to the left-right direction of the wearer. The thickness direction Z is orthogonal to the vertical direction X and the horizontal direction Y.
In the present specification, "vertical direction X upper" means a direction approaching the opening end 50 of the waist opening 1W, and "vertical direction X lower" means a vertical X intermediate portion of the inseam region C described later. It means the direction of approach. That is, "vertical direction X upper side" and "vertical direction X lower side" correspond to the vertical direction of the wearer in the wearing state.
In the present specification, with respect to the thickness direction Z, the side close to the wearer's skin may be referred to as the skin side, and the side close to the clothing may be referred to as the non-skin side. Further, the “skin facing surface” means a surface of the diaper 1 or its constituent members that is directed toward the wearer's skin side when the diaper 1 is worn, that is, a surface that is relatively close to the wearer's skin. The "non-skin facing surface" means a surface of the diaper 1 or its constituent members that is directed to the side opposite to the skin side (clothing side) when the diaper 1 is worn, that is, a surface relatively far from the wearer's skin. do.
"When worn" means a state in which the normally assumed proper wearing position is maintained.

おむつ１は、着用時において着用者の腹側に配置される腹側領域Ａと、着用時において着用者の背側に配置される背側領域Ｂと、腹側領域Ａ及び背側領域Ｂの間に位置し着用時において着用者の股間部に配置される股下領域Ｃと、に区分される。腹側領域Ａと、股下領域Ｃと、背側領域Ｂと、は、縦方向Ｘに沿って配置されている。腹側領域Ａ及び背側領域Ｂは、横方向Ｙの側縁部Ａ１，Ｂ１同士が接合されて、ウエスト開口部１Ｗを形成する。股下領域Ｃには脚繰りが形成され、この脚繰りがレッグ開口部１Ｌを形成する。
なお、図２は、おむつ１を展開し、各部の弾性部材を伸張させて平面状に広げた形態を示す。この態様をおむつ１の「展開伸長形態」とも称する。おむつ１を展開するとは、腹側領域Ａ及び背側領域Ｂの側縁部Ａ１，Ｂ１を分離して展開することを意味する。 The diaper 1 has a ventral region A arranged on the ventral side of the wearer when worn, a dorsal region B arranged on the dorsal side of the wearer when worn, and a ventral region A and a dorsal region B. It is divided into an inseam region C, which is located between them and is arranged in the crotch portion of the wearer when worn. The ventral region A, the inseam region C, and the dorsal region B are arranged along the vertical direction X. In the ventral region A and the dorsal region B, the lateral edge portions A1 and B1 are joined to each other to form a waist opening 1W. A leg roll is formed in the inseam region C, and this leg roll forms the leg opening 1L.
Note that FIG. 2 shows a form in which the diaper 1 is unfolded and the elastic members of each part are stretched and spread out in a plane. This aspect is also referred to as a "expanded / extended form" of the diaper 1. Deploying the diaper 1 means deploying the side edges A1 and B1 of the ventral region A and the dorsal region B separately.

おむつ１は、表面シート２、裏面シート（図示せず）、及び吸収体４０を有する吸収性本体４と、吸収性本体４の非肌対向面側に配置された外装体５と、を備える。
外装体５は、おむつ１の非肌対向面である外面５ａを含む。 The diaper 1 includes a front surface sheet 2, a back surface sheet (not shown), an absorbent main body 4 having an absorbent body 40, and an exterior body 5 arranged on the non-skin facing surface side of the absorbent main body 4.

吸収性本体４は、裏面シート、吸収体４０及び表面シート２が厚み方向Ｚに積層された構成を有する。吸収体４０は、股下領域Ｃにおいて縦方向Ｘに延び、腹側領域Ａと背側領域Ｂの一部まで延出している。吸収体４０は、液保持性の吸収性コアを含み、さらに、当該吸収性コアを被覆するコアラップシートを含んでいてもよい。 The absorbent main body 4 has a structure in which the back surface sheet, the absorber 40, and the front surface sheet 2 are laminated in the thickness direction Z. The absorber 40 extends in the longitudinal direction X in the inseam region C and extends to a part of the ventral region A and the dorsal region B. The absorber 40 includes a liquid-retaining absorbent core, and may further include a core wrap sheet that covers the absorbent core.

吸収性本体４に含まれる各構成（裏面シート、吸収体４０、表面シート２及び後述する防漏カフ）、並びに外装体５等のおむつ１の構成部材に用いられる材料としては、当該技術分野において用いられるものを特に制限なく用いることができる。 Materials used for each configuration (back surface sheet, absorber 40, front surface sheet 2 and leakage-proof cuff described later) included in the absorbent main body 4 and constituent members of the diaper 1 such as the exterior body 5 are in the technical field. What is used can be used without particular limitation.

おむつ１は、さらに、腹側領域Ａ又は背側領域Ｂに設けられた、ウエストギャザー形成用のウエスト用弾性部材２２及び胴回り用弾性部材２３を備えていてもよい。ウエスト用弾性部材２２及び胴回り用弾性部材２３は、横方向Ｙに伸縮可能な糸状又は帯状の弾性部材である。これらの弾性部材２２，２３によって、おむつ１が着用者の身体にフィットし、おむつ１の装着感が高まるとともに、排泄物の漏れが効果的に防止される。 The diaper 1 may further include a waist elastic member 22 for forming waist gathers and a waist elastic member 23 provided in the ventral region A or the dorsal region B. The waist elastic member 22 and the waistline elastic member 23 are thread-shaped or band-shaped elastic members that can be expanded and contracted in the lateral direction Y. These elastic members 22 and 23 allow the diaper 1 to fit the wearer's body, enhance the wearing feeling of the diaper 1, and effectively prevent the leakage of excrement.

［防漏カフの構成］
図２に示すように、吸収性本体４は、横方向Ｙ両側部に配置され、縦方向Ｘに伸縮可能に構成された一対の防漏カフ６をさらに有する。防漏カフ６は、股下領域Ｃにおいて縦方向Ｘに延びており、腹側領域Ａ及び背側領域Ｂまで延出している。 [Asava cuff configuration]
As shown in FIG. 2, the absorbent body 4 further has a pair of leak-proof cuffs 6 arranged on both sides in the lateral direction Y and configured to expand and contract in the vertical direction X. The leak-proof cuff 6 extends in the longitudinal direction X in the inseam region C and extends to the ventral region A and the dorsal region B.

防漏カフ６は、カフ形成用シート６１と、カフ伸縮部６２と、を有する。
カフ形成用シート６１は、液難透過性、水蒸気透過性及び撥水性等の機能を有するシート材で形成される。カフ形成用シート６１は、縦方向Ｘにそれぞれ延びる、基部（図示せず）と、自由端部６１ａと、を含む。基部は、表面シート２、外装体５等の他の構成部材と接合される。自由端部６１ａは、基部の横方向Ｙ中央部側に配置され、大部分が表面シート２等の他の構成部材と接合されていない。カフ形成用シート６１の縦方向Ｘ上端部側は、吸収性本体４の肌対向面側を構成する部材（例えば表面シート２）や、ウエスト開口部１Ｗから折り返された外装体５等とヒートシールや粘着剤等によって接合されている。 The leak-proof cuff 6 has a cuff forming sheet 61 and a cuff expansion / contraction portion 62.
The cuff forming sheet 61 is formed of a sheet material having functions such as poor liquid permeability, water vapor permeability, and water repellency. The cuff forming sheet 61 includes a base portion (not shown) and a free end portion 61a extending in the vertical direction X, respectively. The base is joined to other components such as the surface sheet 2 and the exterior body 5. The free end portion 61a is arranged on the lateral Y center portion side of the base portion, and most of the free end portion 61a is not joined to other constituent members such as the surface sheet 2. The upper end side of the cuff forming sheet 61 in the vertical direction is heat-sealed with a member (for example, the surface sheet 2) constituting the skin-facing surface side of the absorbent main body 4, an exterior body 5 folded back from the waist opening 1W, and the like. It is joined with an adhesive or the like.

カフ伸縮部６２は、縦方向Ｘに延び伸縮可能に構成される。「カフ伸縮部６２が縦方向Ｘに延びる」とは、後述する弾性部材が全体として腹側領域Ａ側から背側領域Ｂ側に向かって延びることを意味し、カフ伸縮部６２の一部が湾曲等している態様も含む。
カフ伸縮部６２は、糸状又は帯状の弾性部材（例えば糸ゴム等）により構成される。カフ伸縮部６２の弾性部材は、例えば、カフ形成用シート６１の自由端部６１ａが折り返された折り返し部の内部に配置される。当該弾性部材は、平面状に引き伸ばされた状態のカフ形成用シート６１に、縦方向Ｘに伸長された状態で取り付けられる。これにより、着用時に、カフ伸縮部６２が縦方向Ｘに収縮して自由端部６１ａが表面シート２から厚み方向Ｚに離間し、肌側に起立する防漏カフ６が実現される。各カフ伸縮部６２は、１又は複数の弾性部材を有しており、図２等に示す例では、２本の弾性部材を有している。 The cuff expansion / contraction portion 62 extends in the vertical direction X and is configured to be expandable / contractible. "The cuff expansion / contraction portion 62 extends in the vertical direction X" means that the elastic member described later extends from the ventral region A side to the dorsal region B side as a whole, and a part of the cuff expansion / contraction portion 62 extends. It also includes aspects such as bending.
The cuff elastic member 62 is composed of a thread-shaped or band-shaped elastic member (for example, rubber thread). The elastic member of the cuff expansion / contraction portion 62 is arranged, for example, inside the folded portion in which the free end portion 61a of the cuff forming sheet 61 is folded back. The elastic member is attached to the cuff forming sheet 61 in a state of being stretched in a plane shape in a state of being stretched in the vertical direction X. As a result, when worn, the cuff expansion / contraction portion 62 contracts in the vertical direction X, the free end portion 61a is separated from the surface sheet 2 in the thickness direction Z, and a leak-proof cuff 6 standing upright on the skin side is realized. Each cuff expansion / contraction portion 62 has one or a plurality of elastic members, and in the example shown in FIG. 2 and the like, it has two elastic members.

カフ伸縮部６２の縦方向Ｘにおける端部６２ａは、上記弾性部材の伸縮可能な領域の端部である。つまり、上記弾性部材の端部が、伸長されていない状態でカフ形成用シート６１に接合されている場合、カフ伸縮部６２の端部６２ａは、上記弾性部材のうち、この非伸縮な部分を除いた最も縦方向Ｘ上方の部分と定義される。具体的に、カフ伸縮部６２の端部６２ａは、弾性部材が伸長されていない状態のおむつ１の防漏カフ６を目視で確認し、弾性部材上のシワが入っている部分とシワが入ってない部分との境界部と定義される。また、各カフ伸縮部６２が複数の弾性部材を有している場合の端部６２ａは、当該複数の弾性部材の上記境界部のうち最も縦方向Ｘ上方に位置する境界部とする。
端部６２ａは、左右のカフ伸縮部６２各々について、腹側領域Ａ側、背側領域Ｂ側の２つずつ存在し、合計で４箇所存在する。 The end portion 62a of the cuff telescopic portion 62 in the vertical direction X is the end portion of the stretchable region of the elastic member. That is, when the end portion of the elastic member is joined to the cuff forming sheet 61 in a non-stretched state, the end portion 62a of the cuff expansion / contraction portion 62 is the non-stretchable portion of the elastic member. It is defined as the part above the vertical X excluding. Specifically, at the end portion 62a of the cuff expansion / contraction portion 62, the leakage-proof cuff 6 of the diaper 1 in a state where the elastic member is not stretched is visually confirmed, and a wrinkled portion and a wrinkle are formed on the elastic member. It is defined as the boundary with the part that does not exist. Further, when each cuff expansion / contraction portion 62 has a plurality of elastic members, the end portion 62a is a boundary portion located at the uppermost position in the vertical direction X among the boundary portions of the plurality of elastic members.
There are two end portions 62a on the ventral side region A side and two on the dorsal side region B side for each of the left and right cuff expansion / contraction portions 62, and there are a total of four end portions 62a.

［廃棄用テープの構成］
図１及び図２に示すように、おむつ１は、吸収性本体４と平面視で重なるように、腹側領域Ａ又は背側領域Ｂに配置された廃棄用テープ１０をさらに備える。本明細書において、「平面視」とは、展開伸長形態のおむつ１を厚み方向Ｚから見た平面視を意味する。また、「廃棄用テープ１０が吸収性本体４と平面視で重なる」態様は、廃棄用テープ１０の一部が吸収性本体４と平面視で重なる態様を含む。

図３に示すように、固定部１１の上端部１１ａ側の部分は、例えば、伸長部１２側（非肌側）に折り返されて、折り返し部を形成している。固定部１１の上端部１１ａは、この折り返し部によって、伸長部１２の上端部１２ａと接続される。
伸長部１２の下端部１２ｂ側の部分は、例えば、止着部１３側（非肌側）に折り返されて、折り返し部を形成している。伸長部１２の下端部１２ｂは、この折り返し部によって、止着部１３の下端部１３ｂと接続される。
このように、図３に示す廃棄用テープ１０は、固定部１１、伸長部１２及び止着部１３がＺ字状に３つ折りされた構成を有する。 As shown in FIG. 3, the portion of the fixed portion 11 on the upper end portion 11a side is folded back to the extended portion 12 side (non-skin side) to form the folded portion. The upper end portion 11a of the fixing portion 11 is connected to the upper end portion 12a of the extending portion 12 by this folded portion.
The portion of the extended portion 12 on the lower end portion 12b side is folded back to, for example, the fastening portion 13 side (non-skin side) to form the folded portion. The lower end portion 12b of the extension portion 12 is connected to the lower end portion 13b of the fastening portion 13 by this folded portion.
As described above, the waste tape 10 shown in FIG. 3 has a structure in which the fixing portion 11, the extending portion 12, and the fastening portion 13 are folded in three in a Z shape.

Can be used without particular limitation. Even when the sheet piece 14 for the fixing portion is stretchable, the stretchability is not exhibited because it is fixed to the outer surface 5a.
The fixing portion adhesive portion 15 fixes the fixing portion sheet piece 14 to the outer surface 5a. The waste tape 10 is non-detachably fixed to the outer surface 5a of the diaper 1 by the adhesive portion 15 for the fixing portion. The adhesive portion 15 for the fixing portion is formed by a known adhesive such as a hot melt adhesive.

The stretchable portion adhesive portion 17 is for peeling and joining the stretchable portion sheet piece 16 onto the first surface 14a of the fixing portion 11 in the laminated state of the above-mentioned waste tape 10.

Specifically, the stress at the start of extension of the extension portion 12 is preferably 5.0 N or less, more preferably 3.0 N or less.
As the sheet piece 16 for such an stretchable portion, for example, an stretchable film can be used. Examples of the film include a single layer film and a multilayer film such as a coextruded film. Further, as the material constituting the stretchable film, a resin film formed by melting and extruding a polyolefin-based resin such as linear low-density polyethylene is preferable. Examples of the polyolefin resin include polypropylene homopolymers; polypropylene copolymers of polypropylene and polyethylene, block copolymers, random copolymers, random block copolymers and the like; blends of the polypropylene homopolymers and the polypropylene copolymers; high-density polyethylene, low. Polyethylene such as density polyethylene and linear low density polyethylene; blends of the polyethylene with the polypropylene homopolymer and / or the polypropylene copolymer and the like, and these include olefin-based, polyester-based, polyamide-based, styrene-based and the like. Various thermoplastic elastomers may be blended and used. Further, in addition to the polyolefin resin, at least one material selected from the group consisting of polyvinyl chloride, ethylene-vinyl acetate copolymer and polyvinyl alcohol is also preferable.

止着部１３は、おむつ１の廃棄時に、廃棄用テープ１０が展開された状態で、おむつ１の外面５ａに止着可能に構成される。
止着部１３は、第１面１８ａ及び第２面１８ｂを含む止着部用シート片１８と、第２面１８ｂに配置された止着部用粘着部１９と、を有している。
止着部用シート片１８は、縦方向Ｘに延びる帯状の非伸縮性のシート片により構成される。止着部用シート片１８は、固定部用シート片１４又は伸長部用シート片１６と同等のサイズを有していてもよいし、異なるサイズを有していてもよい。
止着部用粘着部１９は、上述の廃棄用テープ１０の積層状態において、伸長部１２の第１面１６ａ上に止着部用シート片１８を剥離可能に接合し、かつ止着部１３をおむつ１の外面５ａにおける任意の位置に止着するものである。止着部用粘着部１９の粘着性の程度は、このような観点から決定されることが好ましい。 The fastening portion 13 is configured to be able to be fastened to the outer surface 5a of the diaper 1 in a state where the disposal tape 10 is unfolded when the diaper 1 is discarded.
The fastening portion 13 has a fastening portion sheet piece 18 including a first surface 18a and a second surface 18b, and a fastening portion adhesive portion 19 arranged on the second surface 18b.
The sheet piece 18 for the fastening portion is composed of a strip-shaped non-stretchable sheet piece extending in the vertical direction X. The sheet piece 18 for the fastening portion may have the same size as the sheet piece 14 for the fixing portion or the sheet piece 16 for the extension portion, or may have a different size.
The adhesive portion 19 for the fastening portion is such that the fastening portion sheet piece 18 is detachably bonded to the first surface 16a of the extending portion 12 in the laminated state of the waste tape 10 described above, and the fastening portion 13 is attached. The diaper 1 is attached to an arbitrary position on the outer surface 5a of the diaper 1. It is preferable that the degree of adhesiveness of the adhesive portion 19 for the fastening portion is determined from such a viewpoint.

止着部１３は、非伸縮性である。「非伸縮性」とは、長手方向Ｘ１において伸長性を発現しないか、又は伸長部１２と比較して伸張性が非常に低いことを意味する。具体的に、止着部１３の塑性変形開始時の応力は、好ましくは３０Ｎ以下、より好ましくは２５Ｎ以下である。このような止着部用シート片１８としては、例えば、樹脂性シート（プラスチックシート，フィルム等）、不織布、織布など、従来用いられていた公知のものを特に制限なく用いることができる。止着部１３の塑性変形開始時の応力の測定方法については、後述する。 The fastening portion 13 is non-stretchable. By "non-stretchable" is meant that no extensibility is exhibited in the longitudinal direction X1 or the extensibility is very low as compared with the extensibility portion 12. Specifically, the stress at the start of plastic deformation of the fastening portion 13 is preferably 30 N or less, more preferably 25 N or less. As the sheet piece 18 for the fastening portion, for example, a conventionally used known sheet such as a resin sheet (plastic sheet, film, etc.), a non-woven fabric, or a woven fabric can be used without particular limitation. The method of measuring the stress at the start of plastic deformation of the fastening portion 13 will be described later.

さらに、図３に示す廃棄用テープ１０は、止着部１３の上端部１３ａに接合された摘み部２０を有する。摘み部２０は、廃棄用テープ１０を展開及び伸長する際におむつ１の廃棄者が把持するための部分である。摘み部２０は、把持しやすさの観点から、典型的には接着性を有さない。摘み部２０は、例えば、止着部用シート片１８の第２面１８ｂに接続された、止着部用シート片１８とは別体のシート片で形成される。 Further, the waste tape 10 shown in FIG. 3 has a grip portion 20 joined to the upper end portion 13a of the fastening portion 13. The picking portion 20 is a portion for the discarder of the diaper 1 to grasp when the waste tape 10 is unfolded and stretched. The gripped portion 20 typically has no adhesiveness from the viewpoint of ease of gripping. The grip portion 20 is formed of, for example, a sheet piece that is connected to the second surface 18b of the fastening portion sheet piece 18 and is separate from the fastening portion sheet piece 18.

［おむつ廃棄時の動作及びおむつの廃棄形態］
上記構成の廃棄用テープ１０を用いた、おむつ１を廃棄する際の典型的な動作について説明する。
まず、図４に示すように、使用済みのおむつ１を、腹側領域Ａと背側領域Ｂが肌対向面を内側にして重ねられた状態にする。このとき、股下領域Ｃは縦方向Ｘ中間部において折り曲げられ、腹側領域Ａ及び背側領域Ｂのウエスト開口部１Ｗの開口端５０は、重ねられる。この形態を、おむつ１の「２つ折り形態」とも称する。腹側領域Ａと背側領域Ｂとの側縁部Ａ１，Ｂ１は、分離されていても分離されていなくてもよい。
続いて、廃棄用テープ１０が配置されていない側（例えば腹側領域Ａ）が内側になるように、おむつ１を股下領域Ｃからウエスト開口部１Ｗに向けて丸める。そして、丸められた外面５ａ上に、廃棄用テープ１０が配置された側（例えば背側領域Ｂ）のウエスト開口部１Ｗを被せるようにする。 [Operation when disposing of diapers and disposal form of diapers]
A typical operation when disposing of the diaper 1 using the disposal tape 10 having the above configuration will be described.
First, as shown in FIG. 4, the used diaper 1 is placed in a state where the ventral region A and the dorsal region B are overlapped with the skin facing surface inside. At this time, the inseam region C is bent at the intermediate portion in the vertical direction X, and the opening ends 50 of the waist opening 1W of the ventral region A and the dorsal region B are overlapped. This form is also referred to as a "folded form" of the diaper 1. The side edges A1 and B1 of the ventral region A and the dorsal region B may or may not be separated.
Subsequently, the diaper 1 is rolled from the inseam region C toward the waist opening 1W so that the side on which the disposal tape 10 is not arranged (for example, the ventral region A) is on the inside. Then, the waist opening 1W on the side where the disposal tape 10 is arranged (for example, the dorsal side region B) is covered on the rolled outer surface 5a.

続いて、図５に示すように、廃棄用テープ１０の摘み部２０を指で把持して廃棄用テープ１０の長手方向Ｘ１に引っ張り、廃棄用テープ１０を積層された状態から帯状の状態に展開させる。さらに摘み部２０を長手方向Ｘ１に引っ張ることで、伸長部１２が伸長を開始する。
続いて、伸長した状態の廃棄用テープ１０を、丸められた状態のおむつ１の外面５ａに巻き付ける。そして、おむつ１の外面５ａの任意の位置に、止着部１３を止着させる。
これにより、図６に示すようなおむつ１の廃棄形態が形成される。 Subsequently, as shown in FIG. 5, the grip portion 20 of the disposal tape 10 is grasped with a finger and pulled in the longitudinal direction X1 of the disposal tape 10, and the disposal tape 10 is developed from a laminated state to a strip-shaped state. Let me. Further, by pulling the grip portion 20 in the longitudinal direction X1, the extension portion 12 starts to extend.
Subsequently, the stretched waste tape 10 is wrapped around the outer surface 5a of the rolled diaper 1. Then, the fastening portion 13 is fastened to an arbitrary position on the outer surface 5a of the diaper 1.
As a result, the disposal form of the diaper 1 as shown in FIG. 6 is formed.

本実施形態では、廃棄用テープ１０の位置を、防漏カフ６との関係で以下のように規定することで、上記廃棄動作時に、防漏カフ６による伸長が廃棄用テープ１０の伸長を補助し、廃棄動作をより円滑に、かつ確実に行うことができる。 In the present embodiment, the position of the waste tape 10 is defined as follows in relation to the leakage-proof cuff 6, so that the extension by the leakage-proof cuff 6 assists the extension of the disposal tape 10 during the above-mentioned disposal operation. However, the disposal operation can be performed more smoothly and reliably.

［廃棄用テープと防漏カフとの位置関係］
図７の拡大図等に示すように、廃棄用テープ１０の固定部１１の下端部１１ｂと、ウエスト開口部１Ｗの開口端５０との間の縦方向Ｘに沿った距離Ｄ１は、カフ伸縮部６２の端部６２ａと、開口端５０との間の縦方向Ｘに沿った距離Ｄ２以上である。つまり、固定部１１の少なくとも一部は、平面視において、カフ伸縮部６２と縦方向Ｘに重なるように配置される。距離Ｄ１，Ｄ２は、図２及び図７のような展開伸長形態において測定された距離とする。
また、距離Ｄ１は、腹側領域Ａ側に位置する端部６２ａと開口端５０との間の距離Ｄ２、又は、背側領域Ｂ側に位置する端部６２ａと開口端５０との間の距離Ｄ２のうち、小さい方の距離Ｄ２以上であればよい。特に、後述する作用効果を効果的に発揮する観点から、距離Ｄ１は、図７に示すように、廃棄用テープ１０が配置されている背側領域Ｂ又は腹側領域Ａ側に位置する端部６２ａと開口端５０との間の距離Ｄ２以上であることが好ましい。 [Positional relationship between waste tape and leak-proof cuff]
As shown in the enlarged view of FIG. 7, the distance D1 along the vertical direction X between the lower end portion 11b of the fixing portion 11 of the waste tape 10 and the opening end 50 of the waist opening 1W is the cuff expansion / contraction portion. The distance D2 or more along the vertical direction X between the end portion 62a of 62 and the opening end 50. That is, at least a part of the fixed portion 11 is arranged so as to overlap the cuff expansion / contraction portion 62 in the vertical direction X in a plan view. The distances D1 and D2 are the distances measured in the expanded / extended form as shown in FIGS. 2 and 7.
Further, the distance D1 is the distance D2 between the end portion 62a located on the ventral region A side and the opening end 50, or the distance between the end portion 62a located on the dorsal region B side and the opening end 50. Of D2, the smaller distance D2 or more may be used. In particular, from the viewpoint of effectively exerting the effects described later, the distance D1 is an end portion located on the dorsal region B or ventral region A side on which the disposal tape 10 is arranged, as shown in FIG. The distance D2 or more between 62a and the opening end 50 is preferable.

廃棄用テープ１０をこのように配置することで、固定部１１の下端部１１ｂと、カフ伸縮部６２の端部６２ａの距離が近くなる。これにより、おむつ１（吸収性物品）の廃棄のために廃棄用テープ１０を引っ張った場合に、引張力が防漏カフ６のカフ伸縮部６２にも作用しやすくなる。つまり、当該引張力によって、廃棄用テープ１０が伸長するとともに、防漏カフ６のカフ伸縮部６２が伸長し得る。カフ伸縮部６２は、糸ゴム等の容易に伸長可能な弾性部材で形成され得る。したがって、この構成により、おむつ１（吸収性物品）の廃棄者が、廃棄用テープ１０が小さい荷重でスムースに伸長する感じを得ることができる。
さらに、当該引張力によって防漏カフ６も伸長されることで、引張力のエネルギが防漏カフ６の伸長によって消費され、伸長部１２が過剰に伸長されることを防止できる。また、廃棄者が伸長しやすい感じを得ることでも、廃棄者が廃棄用テープ１０に対して過剰な引張力を付加しにくくなり、伸長部１２の過剰な伸長が防止される。これらにより、伸長部１２が塑性変形するまで伸長されるリスクを低減でき、廃棄用テープ１０の強度低下に伴う破断が抑制される。
以上のように、本実施形態のおむつ１（吸収性物品）によれば、防漏カフ６の伸長によって伸長部１２の伸長が補助され、廃棄用テープ１０が伸長しやすく感じられるとともに、廃棄用テープ１０の破断が抑制される。これにより、廃棄用テープ１０によるおむつ１（吸収性物品）の廃棄を円滑に行うことができ、おむつ１（吸収性物品）の上記廃棄形状を確実に形成することができる。 By arranging the waste tape 10 in this way, the distance between the lower end portion 11b of the fixing portion 11 and the end portion 62a of the cuff expansion / contraction portion 62 becomes close. As a result, when the disposal tape 10 is pulled for disposal of the diaper 1 (absorbent article), the tensile force easily acts on the cuff expansion / contraction portion 62 of the leakage-proof cuff 6. That is, due to the tensile force, the waste tape 10 can be stretched, and the cuff expansion / contraction portion 62 of the leakage-proof cuff 6 can be stretched. The cuff stretchable portion 62 can be formed of an easily stretchable elastic member such as a rubber thread. Therefore, with this configuration, the disposer of the diaper 1 (absorbent article) can feel that the disposal tape 10 is smoothly stretched with a small load.
Further, since the leak-proof cuff 6 is also stretched by the tensile force, the energy of the tensile force is consumed by the stretching of the leak-proof cuff 6, and it is possible to prevent the stretched portion 12 from being excessively stretched. Further, even if the discarder feels that the waste is easily stretched, it becomes difficult for the discarder to apply an excessive tensile force to the waste tape 10, and the excessive stretch of the stretched portion 12 is prevented. As a result, the risk of the stretched portion 12 being stretched until it is plastically deformed can be reduced, and the breakage of the waste tape 10 due to the decrease in strength is suppressed.
As described above, according to the diaper 1 (absorbent article) of the present embodiment, the extension of the leak-proof cuff 6 assists the extension of the extension portion 12, and the disposal tape 10 feels easy to extend and is for disposal. Breaking of the tape 10 is suppressed. As a result, the diaper 1 (absorbent article) can be smoothly disposed of by the disposal tape 10, and the disposal shape of the diaper 1 (absorbent article) can be reliably formed.

また、おむつ１の廃棄者が、廃棄用テープ１０に対して過剰な引張力を付加しにくくなるため、固定部１１が外面５ａから脱離するリスクを低下させることができる。さらにこれに伴い、固定部１１の固定部用粘着部１５の粘着剤の使用量を制限することができ、固定部１１による着用時の違和感等を抑制することもできる。 Further, since it is difficult for the disposer of the diaper 1 to apply an excessive tensile force to the disposal tape 10, the risk that the fixing portion 11 is detached from the outer surface 5a can be reduced. Further, along with this, it is possible to limit the amount of the adhesive used in the fixing portion adhesive portion 15 of the fixing portion 11, and it is also possible to suppress a feeling of strangeness when worn by the fixing portion 11.

また、排便時等では、腹側領域Ａ及び背側領域Ｂの側縁部Ａ１，Ｂ１を分離した後に、おむつ１を丸めて廃棄することがある。このような場合には、廃棄用テープ１０に付加される引張力が、廃棄用テープ１０の配置されている領域（背側領域Ｂ又は腹側領域Ａ）に、より直接的に作用し得る。このため、距離Ｄ１が、廃棄用テープ１０の配置された背側領域Ｂ又は腹側領域Ａに位置する端部６２ａと開口端５０との間の距離Ｄ２以上となる場合に、腹側領域Ａ及び背側領域Ｂの側縁部Ａ１，Ｂ１を分離することで、当該引張力がカフ伸縮部６２により伝搬しやすくなる。したがって、カフ伸縮部６２がより伸長しやすくなり、上述の作用効果を、より一層確実に得ることができる。 Further, at the time of defecation or the like, after separating the side edge portions A1 and B1 of the ventral region A and the dorsal region B, the diaper 1 may be rolled up and discarded. In such a case, the tensile force applied to the waste tape 10 may act more directly on the region (dorsal region B or ventral region A) where the waste tape 10 is arranged. Therefore, when the distance D1 is equal to or greater than the distance D2 between the end portion 62a located in the dorsal region B or the ventral region A where the disposal tape 10 is arranged and the open end 50, the ventral region A. By separating the side edge portions A1 and B1 of the dorsal region B, the tensile force can be easily propagated by the cuff expansion / contraction portion 62. Therefore, the cuff expansion / contraction portion 62 becomes easier to expand, and the above-mentioned action and effect can be obtained more reliably.

［カフ伸縮部の伸長性］
上述の廃棄用テープ１０の伸長を補助する効果をより確実に得る観点から、カフ伸縮部６２の伸長性は、廃棄用テープ１０の伸長性との関係で規定されることが好ましい。 [Extension of cuff elastic part]
From the viewpoint of more reliably obtaining the effect of assisting the elongation of the waste tape 10 described above, the extensibility of the cuff elastic portion 62 is preferably defined in relation to the extensibility of the waste tape 10.

まず、廃棄用テープ１０に長手方向Ｘ１の荷重を付加した場合の態様について説明する。
廃棄用テープ１０に長手方向Ｘ１の荷重を付加すると、まず積層構造の廃棄用テープ１０が長尺状に展開される。その後、伸長部１２が、所定の応力（第１の応力とする）において伸長を開始する。そして、廃棄用テープ１０に長手方向Ｘ１の荷重を付加し続けると、伸長部１２が、第１の応力よりも大きい所定の応力（第２の応力とする）において塑性変形を開始する。さらに廃棄用テープ１０に対して長手方向Ｘ１に荷重を付加し続けると、廃棄用テープ１０が、第２の応力よりも大きい所定の応力において破断する。あるいは、止着部１３が、第２の応力よりも大きい所定の応力において塑性変形し、その後廃棄用テープ１０が破断することもある。廃棄用テープ１０は、塑性変形すると強度が低下することから、伸長開始から塑性変形の開始までの段階で、丸めた形状のおむつ１に巻き付けられることが好ましい。
なお、本明細書において、「廃棄用テープ１０の伸長開始時の応力（第１の応力）」とは、伸長部１２の伸長開始時の応力を意味し、「廃棄用テープ１０の塑性変形開始時の応力（第２の応力）」とは、伸長部１２の塑性変形開始時の応力を意味するものとする。 First, a mode in which a load in the longitudinal direction X1 is applied to the waste tape 10 will be described.
When a load in the longitudinal direction X1 is applied to the waste tape 10, the waste tape 10 having a laminated structure is first developed in a long shape. After that, the stretching portion 12 starts stretching at a predetermined stress (which is regarded as the first stress). Then, when the load in the longitudinal direction X1 is continuously applied to the waste tape 10, the extension portion 12 starts plastic deformation at a predetermined stress (referred to as a second stress) larger than the first stress. Further, when a load is continuously applied to the waste tape 10 in the longitudinal direction X1, the waste tape 10 breaks at a predetermined stress larger than the second stress. Alternatively, the fastening portion 13 may be plastically deformed at a predetermined stress larger than the second stress, and then the disposal tape 10 may be broken. Since the strength of the waste tape 10 decreases when it is plastically deformed, it is preferable that the waste tape 10 be wound around the rolled diaper 1 at the stage from the start of elongation to the start of plastic deformation.
In the present specification, the "stress at the start of stretching of the waste tape 10 (first stress)" means the stress at the start of stretching of the stretched portion 12, and the "start of plastic deformation of the waste tape 10". The “stress at time (second stress)” means the stress at the start of plastic deformation of the elongated portion 12.

そこで、防漏カフ６のカフ伸縮部６２の伸長開始時の応力は、廃棄用テープ１０の塑性変形開始時の応力（第２の応力）よりも小さいことが好ましい。これにより、廃棄用テープ１０が塑性変形に到る前の弾性変形している段階で、カフ伸縮部６２が伸長を開始し得る。したがって、廃棄用テープ１０の塑性変形前において、廃棄者からの引張力のエネルギがカフ伸縮部６２の伸長によって消費されるとともに、廃棄者がスムースに伸長する感覚を得やすくなり、廃棄用テープ１０の塑性変形がより効果的に抑制される。 Therefore, it is preferable that the stress at the start of extension of the cuff expansion / contraction portion 62 of the leak-proof cuff 6 is smaller than the stress at the start of plastic deformation of the waste tape 10 (second stress). As a result, the cuff expansion / contraction portion 62 can start stretching at the stage where the waste tape 10 is elastically deformed before reaching plastic deformation. Therefore, before the plastic deformation of the waste tape 10, the energy of the tensile force from the waste is consumed by the elongation of the cuff expansion / contraction portion 62, and it becomes easier for the waste to get a feeling of smooth expansion, and the waste tape 10 Plastic deformation is suppressed more effectively.

また、防漏カフ６のカフ伸縮部６２の伸長開始時の応力は、廃棄用テープ１０の伸長開始時の応力（第１の応力）よりも小さいことが好ましい。廃棄用テープ１０が伸長を開始する前にカフ伸縮部６２が伸長を開始することで、廃棄用テープ１０の引張操作の初期段階の荷重が軽く感じられる。これにより、おむつ１の廃棄者が、伸長の初期段階において、廃棄用テープ１０が小さい荷重でスムースに伸長する感覚をより確実に得ることができる。 Further, it is preferable that the stress at the start of extension of the cuff expansion / contraction portion 62 of the leakage-proof cuff 6 is smaller than the stress at the start of extension of the waste tape 10 (first stress). Since the cuff expansion / contraction portion 62 starts stretching before the waste tape 10 starts stretching, the load at the initial stage of the pulling operation of the waste tape 10 is felt lightly. As a result, the disposer of the diaper 1 can more reliably obtain the feeling that the disposal tape 10 is smoothly stretched with a small load in the initial stage of stretching.

図３に示すように、固定部１１の少なくとも一部は、外装体５と吸収性本体４とが接合された接合領域Ｓ上に配置されることが好ましい。「固定部１１の少なくとも一部が接合領域Ｓ上に配置される」態様は、固定部１１の少なくとも一部が、接合領域Ｓの少なくとも一部の上に配置される態様を含む。
接合領域Ｓは、外装体５と吸収性本体４の非肌対向面側の構成部材（例えば裏面シート）が、粘着剤、融着等の公知の接合方法によって接合されている領域を意味する。図３に示す例では、接合領域Ｓにおいて、外装体５と吸収性本体４とが、ホットメルト粘着剤等の粘着剤Ｓ１を介して接合されている。
接合領域Ｓは、例えば、帯状、線状又はドット状等の平面形状を有する複数の小領域を含んでいてもよい。これらの小領域は、厚み方向Ｚに直交する平面方向に、間欠的に配置され得る。この場合、固定部１１の少なくとも一部が、１又は複数の上記小領域の上に配置されることが好ましい。 [More detailed arrangement of fixed parts]
As shown in FIG. 3, it is preferable that at least a part of the fixing portion 11 is arranged on the joining region S where the exterior body 5 and the absorbent body 4 are joined. The aspect of "at least a part of the fixing portion 11 is arranged on the joining region S" includes an aspect in which at least a part of the fixing portion 11 is arranged on at least a part of the joining region S.
The joining region S means a region where the exterior body 5 and the constituent member (for example, the back surface sheet) on the non-skin facing surface side of the absorbent main body 4 are joined by a known joining method such as an adhesive or fusion. In the example shown in FIG. 3, in the bonding region S, the exterior body 5 and the absorbent main body 4 are bonded via an adhesive S1 such as a hot melt adhesive.
The joining region S may include, for example, a plurality of small regions having a planar shape such as a band shape, a linear shape, or a dot shape. These small regions may be arranged intermittently in a plane direction orthogonal to the thickness direction Z. In this case, it is preferable that at least a part of the fixing portion 11 is arranged on one or more of the small regions.

固定部１１の少なくとも一部が接合領域Ｓ上に配置されることで、廃棄用テープ１０を引っ張る引張力が、接合領域Ｓを介して吸収性本体４に伝搬しやすくなる。これにより、当該引張力によって吸収性本体４の防漏カフ６がより伸長しやすくなる。したがって、防漏カフ６の伸長によって廃棄用テープ１０の伸長が補助される効果がより得られやすくなる。 By arranging at least a part of the fixing portion 11 on the joint region S, the tensile force pulling the waste tape 10 is easily propagated to the absorbent main body 4 through the joint region S. As a result, the leakage-proof cuff 6 of the absorbent main body 4 becomes more easily stretched by the tensile force. Therefore, it becomes easier to obtain the effect that the elongation of the waste tape 10 is assisted by the elongation of the leakage-proof cuff 6.

また、図７に示すように、固定部１１の下端部１１ｂと、カフ伸縮部６２の端部６２ａとの間の縦方向Ｘに沿った距離Ｄ３は、固定部１１の縦方向Ｘにおける寸法Ｌの５０％以下であることが好ましい。距離Ｄ３は、固定部１１の下端部１１ｂと開口端５０との間の縦方向Ｘに沿った距離Ｄ１と、カフ伸縮部６２の端部６２ａと開口端５０との間の距離Ｄ２との差分として算出することができる。
また、距離Ｄ３の算出に用いられる端部６２ａは、腹側領域Ａ側に位置する端部６２ａ、又は、背側領域Ｂ側に位置する端部６２ａのうち、距離Ｄ２が小さい方の距離Ｄ２とする。
これにより、固定部１１の上端部１１ａ側の領域が、カフ伸縮部６２の縦方向Ｘ上方に位置することになる。したがって、固定部１１の上端部１１ａ側の領域が、カフ伸縮部６２の伸縮の影響を受けにくくなり、固定部１１と外装体５との接合が一層安定する。 Further, as shown in FIG. 7, the distance D3 along the vertical direction X between the lower end portion 11b of the fixed portion 11 and the end portion 62a of the cuff telescopic portion 62 is the dimension L in the vertical direction X of the fixed portion 11. It is preferably 50% or less of. The distance D3 is the difference between the distance D1 along the vertical direction X between the lower end portion 11b of the fixed portion 11 and the opening end 50 and the distance D2 between the end portion 62a of the cuff telescopic portion 62 and the opening end 50. Can be calculated as.
Further, the end portion 62a used for calculating the distance D3 is the end portion 62a located on the ventral side region A side or the end portion 62a located on the dorsal side region B side, whichever has the smaller distance D2. And.
As a result, the region on the upper end portion 11a side of the fixing portion 11 is located above the vertical direction X of the cuff expansion / contraction portion 62. Therefore, the region on the upper end portion 11a side of the fixing portion 11 is less likely to be affected by the expansion and contraction of the cuff expansion / contraction portion 62, and the bonding between the fixing portion 11 and the exterior body 5 becomes more stable.

また、図２及び図７等に示すように、外装体５には、一対のレッグ開口部１Ｌに沿ってレッグ用弾性部材２１が配置されている。レッグ用弾性部材２１は、１又は複数の糸状又は帯状の弾性部材（例えば糸ゴム等）を含む。レッグ用弾性部材２１は、図２及び図７のような展開伸長形態において、縦方向Ｘに沿って延びる。「レッグ用弾性部材２１が縦方向Ｘに延びる」とは、レッグ用弾性部材２１が股下領域Ｃの縦方向Ｘ中間部から縦方向Ｘ上方に向かって延びていることを意味する。
レッグ用弾性部材２１の縦方向Ｘ上方における上端部２１ａは、図２及び図７のような展開伸長形態において、レッグ用弾性部材２１のうち最も縦方向Ｘ上方に位置する部分である。図２及び図７に示す例では、上端部２１ａは、腹側領域Ａ及び背側領域Ｂの側縁部Ａ１，Ｂ１に位置する。 Further, as shown in FIGS. 2 and 7, in the exterior body 5, leg elastic members 21 are arranged along the pair of leg openings 1L. The leg elastic member 21 includes one or more thread-shaped or band-shaped elastic members (for example, rubber thread). The leg elastic member 21 extends along the vertical direction X in the expanded / extended form as shown in FIGS. 2 and 7. "The leg elastic member 21 extends in the vertical direction X" means that the leg elastic member 21 extends in the vertical direction X upward from the vertical X intermediate portion of the inseam region C.
The upper end portion 21a of the leg elastic member 21 above the vertical direction X is the portion of the leg elastic member 21 located most above the vertical X in the expanded / extended form as shown in FIGS. 2 and 7. In the example shown in FIGS. 2 and 7, the upper end portion 21a is located at the side edge portions A1 and B1 of the ventral region A and the dorsal region B.

廃棄用テープ１０の伸長時におけるレッグ用弾性部材２１の伸長の影響を抑制する観点から、固定部１１の下端部１１ｂと開口端５０との間の縦方向Ｘに沿った距離Ｄ１は、レッグ用弾性部材２１の上端部２１ａと開口端５０との間の縦方向Ｘに沿った距離Ｄ４よりも小さいことが好ましい。つまり、固定部１１の下端部１１ｂは、上端部２１ａよりも縦方向Ｘ上方に位置することが好ましい。
これにより、廃棄用テープ１０を伸長させる際の引張力が、レッグ用弾性部材２１に作用することを抑制でき、当該引張力によってレッグ用弾性部材２１が伸長することが抑制される。したがって、この構成により、廃棄用テープ１０の伸長とともにおむつ１が縦方向Ｘに伸びすぎて、引張力を弱めた際に過剰に収縮するような不具合を抑制することができる。 From the viewpoint of suppressing the influence of the extension of the leg elastic member 21 when the waste tape 10 is extended, the distance D1 along the vertical direction X between the lower end 11b of the fixing portion 11 and the opening end 50 is for the leg. It is preferably smaller than the distance D4 along the vertical direction X between the upper end 21a of the elastic member 21 and the opening end 50. That is, it is preferable that the lower end portion 11b of the fixed portion 11 is located above the upper end portion 21a in the vertical direction X.
As a result, the tensile force when stretching the waste tape 10 can be suppressed from acting on the leg elastic member 21, and the leg elastic member 21 is suppressed from being stretched by the tensile force. Therefore, with this configuration, it is possible to suppress a problem that the diaper 1 is stretched too much in the vertical direction X with the stretching of the waste tape 10 and is excessively shrunk when the tensile force is weakened.

（防漏カフの伸縮開始時の応力の測定方法）
防漏カフ６のカフ形成用シート６１を吸収性本体４の表面シート２等から剥離した状態とする。続いて、防漏カフ６の長手方向を引張方向に一致させ、チャック間距離を１００ｍｍとして、防漏カフ６を引張試験機（例えば株式会社オリエンテック製、機種「ＲＴＡ－１００」）のチャックに取り付ける。防漏カフ６をチャックに取り付ける際、カフ伸縮部６２の両端部をチャックに取り付ける。次いで、３００ｍｍ／ｍｉｎの速度で引っ張り、引張距離に伴って変化する引張荷重（応力）を測定する。
測定直後は、防漏カフ６が長手方向に張った状態となるまで、防漏カフ６が伸長せずに引張距離が大きくなる。その後、ある点において応力（Ｎ）－伸びの曲線の傾きが変化し、応力が引張距離にほぼ比例して増大する。この傾きが最初に変化する点の応力を、防漏カフ６のカフ伸縮部６２の伸長開始時の応力（Ｎ）とする。 (Measuring method of stress at the start of expansion and contraction of the leak-proof cuff)
The cuff forming sheet 61 of the leak-proof cuff 6 is in a state of being peeled off from the surface sheet 2 or the like of the absorbent main body 4. Subsequently, the longitudinal direction of the leak-proof cuff 6 is made to match the tensile direction, the distance between the chucks is set to 100 mm, and the leak-proof cuff 6 is used as a chuck of a tensile tester (for example, manufactured by Orientec Co., Ltd., model "RTA-100"). Install. When attaching the leak-proof cuff 6 to the chuck, both ends of the cuff telescopic portion 62 are attached to the chuck. Next, the tensile load (stress) that changes with the tensile distance is measured by pulling at a speed of 300 mm / min.
Immediately after the measurement, the leakage-proof cuff 6 does not extend and the tensile distance increases until the leakage-proof cuff 6 is stretched in the longitudinal direction. Then, at some point, the slope of the stress (N) -elongation curve changes, and the stress increases in proportion to the tensile distance. The stress at the point where the inclination first changes is defined as the stress (N) at the start of extension of the cuff expansion / contraction portion 62 of the leak-proof cuff 6.

（廃棄用テープの応力の測定方法）

測定直後は、伸長部１２が長手方向Ｘ１に張った状態となるまで、伸長部１２が伸長せずに引張距離が大きくなる。その後、ある点において応力（Ｎ）－伸びの曲線の傾きが大きく変化し、応力が伸びにほぼ比例して増大し始める。この傾きが最初に変化する点の応力を、廃棄用テープ１０（伸長部１２）の伸長開始時の応力である第１の応力（Ｎ）とする。
伸長部１２が伸長を開始してからさらに引張距離を増大させると、ある点において応力（Ｎ）－伸びの曲線の傾きが小さくなり、引張距離に対して応力がほとんど変化しない点が現れる。この伸長開始後に傾きが大きく変化する点の応力を、廃棄用テープ１０（伸長部１２）の塑性変形開始時の応力である第２の応力（Ｎ）とする。第２の応力（Ｎ）は、応力（Ｎ）－伸びの曲線の変曲点となり得る。

Then, at some point, the slope of the stress (N) -elongation curve changes significantly, and the stress begins to increase in proportion to the elongation. The stress at the point where the slope first changes is defined as the first stress (N), which is the stress at the start of stretching of the waste tape 10 (stretching portion 12).
When the tensile distance is further increased after the extension portion 12 starts stretching, the slope of the stress (N) -elongation curve becomes small at a certain point, and a point where the stress hardly changes with respect to the tension distance appears. The stress at the point where the inclination changes significantly after the start of stretching is defined as the second stress (N), which is the stress at the start of plastic deformation of the waste tape 10 (stretched portion 12). The second stress (N) can be the inflection of the stress (N) -elongation curve.
When the tensile distance is further increased after the stretched portion 12 starts plastic deformation, the stress becomes the maximum value at a certain point, and then the stretched portion 12 breaks.

測定直後は、止着部１３が長手方向に張った状態となるまで、止着部１３が伸長せずに引張距離が大きくなる。その後、ある点において応力（Ｎ）－伸びの曲線の傾きが大きく変化し、応力が伸びにほぼ比例して増大し始める。この傾きが最初に変化する点の応力を、止着部１３が伸長を開始する伸長開始時の応力（Ｎ）とする。
止着部１３が伸長を開始してからさらに引張距離を増大させると、ある点において応力（Ｎ）－伸びの曲線の傾きが小さくなり、引張距離に対して応力がほとんど変化しない点が現れる。この伸長開始後に傾きが大きく変化する点の応力を、止着部１３の塑性変形開始時の応力（Ｎ）とする。止着部１３の塑性変形開始時の応力（Ｎ）は、応力（Ｎ）－伸びの曲線の変曲点となり得る。 (Measuring method of stress at the start of plastic deformation of the anchorage)

The stress at the point where the inclination first changes is defined as the stress (N) at the start of extension when the fastening portion 13 starts extension.
When the tensile distance is further increased after the fastening portion 13 starts stretching, the slope of the stress (N) -elongation curve becomes small at a certain point, and a point where the stress hardly changes with respect to the tensile distance appears. The stress at the point where the inclination changes significantly after the start of the elongation is defined as the stress (N) at the start of the plastic deformation of the fastening portion 13.

［カフ伸縮部の伸長開始時の応力の測定］
実施例１～４並びに比較例１及び２の防漏カフを用いて、カフ伸縮部の伸長開始時の応力（Ｎ）を測定した。まず、防漏カフのカフ形成用シートを吸収性本体の表面シートから剥離した状態とした。続いて、防漏カフの長手方向を引張方向に一致させ、チャック間距離を１００ｍｍとして、防漏カフの両端部を引張試験機（株式会社オリエンテック製、機種「ＲＴＡ－１００」）のチャックに取り付けた。次いで、３００ｍｍ／ｍｉｎの速度で防漏カフを引っ張り、引張距離に伴って変化する引張荷重（応力）を測定した。
上述のように、応力（Ｎ）－伸びの曲線の傾きが最初に大きく変化し、応力が伸びにほぼ比例して増大し始めた点をカフ伸縮部の伸長開始時の応力（Ｎ）とした。その結果、表１に示すように、実施例１～４並びに比較例１及び２のいずれも、カフ伸縮部の伸長開始時の応力（Ｎ）は、０．０２Ｎであった。 [Measurement of stress at the start of extension of the cuff expansion / contraction part]
Using the leak-proof cuffs of Examples 1 to 4 and Comparative Examples 1 and 2, the stress (N) at the start of extension of the cuff expansion / contraction portion was measured. First, the cuff-forming sheet of the leak-proof cuff was separated from the surface sheet of the absorbent body. Subsequently, the longitudinal direction of the leak-proof cuff is matched with the tensile direction, the distance between the chucks is set to 100 mm, and both ends of the leak-proof cuff are used as chucks of a tensile tester (manufactured by Orientec Co., Ltd., model "RTA-100"). I installed it. Next, the leak-proof cuff was pulled at a speed of 300 mm / min, and the tensile load (stress) that changed with the tensile distance was measured.
As described above, the point at which the slope of the stress (N) -elongation curve first changed significantly and the stress began to increase in almost proportional to the elongation was defined as the stress (N) at the start of elongation of the cuff expansion / contraction part. .. As a result, as shown in Table 1, in each of Examples 1 to 4 and Comparative Examples 1 and 2, the stress (N) at the start of extension of the cuff expansion / contraction portion was 0.02N.

［廃棄用テープの伸長開始時及び塑性変形開始時の応力の測定］
実施例１～４並びに比較例１及び２の廃棄用テープの伸長部を固定部から剥離し、長手方向に延ばした展開状態にした。次いで、伸長部の長手方向を引張方向に一致させ、チャック間距離を３０ｍｍとして、伸長部を引張試験機（株式会社オリエンテック製、機種「ＲＴＡ－１００」）のチャックに取り付けた。伸長部をチャックに取り付けた際、止着部との接合箇所及び固定部との接合箇所を避け、これら両接合箇所間をチャックに取り付けた。上記引張試験機によって、３００ｍｍ／ｍｉｎの速度で伸長部を引っ張り、引張距離に伴って変化する応力（荷重）を測定した。
上述のように、応力（Ｎ）－伸びの曲線の傾きが最初に大きく変化し、応力が伸びにほぼ比例して増大し始めた点を、廃棄用テープの伸長開始時の応力とした。また、伸長時から傾きが大きく変化し、応力が伸びに比例せずに変化し始めた点の応力を、廃棄用テープの塑性変形開始時の応力とした。
表１に示すように、実施例１～４並びに比較例１及び２のいずれも、廃棄用テープの伸長開始時の応力は、２Ｎであり、塑性変形開始時の応力は、８Ｎであった。
つまり、各実施例及び比較例のおむつでは、カフ伸縮部の伸長開始時の応力は、廃棄用テープの塑性変形開始時の応力及び伸長開始時の応力よりも小さかった。 [Measurement of stress at the start of stretching and plastic deformation of the waste tape]
The stretched portion of the waste tapes of Examples 1 to 4 and Comparative Examples 1 and 2 was peeled off from the fixed portion, and the stretched portion was stretched in the longitudinal direction. Next, the longitudinal direction of the extended portion was made to match the tensile direction, the distance between the chucks was set to 30 mm, and the extended portion was attached to the chuck of a tensile tester (manufactured by Orientec Co., Ltd., model "RTA-100"). When the extended portion was attached to the chuck, the joint portion with the fastening portion and the joint portion with the fixed portion were avoided, and the space between the two joint portions was attached to the chuck. With the above tensile tester, the stretched portion was pulled at a speed of 300 mm / min, and the stress (load) changing with the tensile distance was measured.
As described above, the point at which the slope of the stress (N) -elongation curve first changed significantly and the stress began to increase in substantially proportional to the elongation was defined as the stress at the start of elongation of the waste tape. Further, the stress at the point where the inclination changed significantly from the time of elongation and the stress began to change in proportion to the elongation was defined as the stress at the start of plastic deformation of the waste tape.
As shown in Table 1, in each of Examples 1 to 4 and Comparative Examples 1 and 2, the stress at the start of elongation of the waste tape was 2N, and the stress at the start of plastic deformation was 8N.
That is, in the diapers of each Example and Comparative Example, the stress at the start of elongation of the cuff expansion / contraction portion was smaller than the stress at the start of plastic deformation of the waste tape and the stress at the start of elongation.

［廃棄テープの伸長しやすさについての評価］
実施例１～４並びに比較例１及び２で得られたおむつを対象として、１６０ｇのイオン交換水を注入した。続いて、おむつを巻き上げて丸め、廃棄用テープで固定する動作を３０人のモニターに行わせた。そのときの廃棄用テープの伸長し易さを評価させ、以下の判定基準に分類した。
＜判定基準＞
Ａ：８割以上のモニターが、伸長し易いと回答した。
Ｂ：５割以上８割未満のモニターが、伸長し易いと回答した。
Ｃ：５割未満のモニターが、伸長し易いと回答した。 [Evaluation of the ease of elongation of waste tape]
160 g of ion-exchanged water was injected into the diapers obtained in Examples 1 to 4 and Comparative Examples 1 and 2. Subsequently, 30 monitors were asked to wind up the diaper, roll it up, and fix it with waste tape. The ease of elongation of the waste tape at that time was evaluated and classified into the following criteria.
<Judgment criteria>
A: More than 80% of monitors answered that they are easy to expand.
B: Monitors with 50% or more and less than 80% answered that they are easy to grow.
C: Less than 50% of monitors answered that they are easy to stretch.

表１に示すように、廃棄用テープの伸長しやすさは、実施例１～４についてはいずれもＡ評価であったが、比較例１はＢ評価、比較例２はＣ評価であった。この結果から、実施例１～４の廃棄用テープは、比較例１及び２の廃棄用テープと比較して、伸長し易く感じられることがわかった。 As shown in Table 1, the ease of elongation of the waste tape was evaluated as A in all of Examples 1 to 4, but evaluated as B in Comparative Example 1 and C in Comparative Example 2. From this result, it was found that the waste tapes of Examples 1 to 4 seemed to be more easily stretched than the waste tapes of Comparative Examples 1 and 2.

［廃棄テープの破断についての評価］
実施例１～４並びに比較例１及び２で得られたおむつを対象として、１６０ｇのイオン交換水を注入した。続いて、おむつを巻き上げて丸め、廃棄用テープで固定する動作を３０人のモニターに行わせた。その時の廃棄動作によって廃棄用テープが破断したものの割合を、廃棄用テープの破断割合（％）として算出した。 [Evaluation of breakage of waste tape]
160 g of ion-exchanged water was injected into the diapers obtained in Examples 1 to 4 and Comparative Examples 1 and 2. Subsequently, 30 monitors were asked to wind up the diaper, roll it up, and fix it with waste tape. The percentage of the waste tape broken by the disposal operation at that time was calculated as the break ratio (%) of the waste tape.

表１に示すように、実施例１～４のおむつにおける廃棄用テープの破断割合は、いずれも７％以下であったが、比較例１及び２のおむつにおける廃棄用テープの破断割合は、１３％及び２０％であった。この結果から、実施例１～４の廃棄用テープは、比較例１及び２の廃棄用テープと比較して、廃棄動作中の破断が少ないことがわかった。 As shown in Table 1, the breaking rate of the waste tape in the diapers of Examples 1 to 4 was 7% or less, but the breaking rate of the waste tape in the diapers of Comparative Examples 1 and 2 was 13. % And 20%. From this result, it was found that the disposal tapes of Examples 1 to 4 had less breakage during the disposal operation as compared with the disposal tapes of Comparative Examples 1 and 2.

［総括］
以上のように、固定部の下端部がカフ伸縮部の端部よりも縦方向下方に配置されている実施例１～４のおむつは、比較例１及び２のおむつと比較して、伸長しやすく、かつ、破断しにくいため、廃棄用テープによる廃棄を円滑かつ確実に行うことができる。 [Summary]
