特開２０１２−２２８４２３号公報JP 2012-228423 A

特許文献１に開示の使い捨て着用物品によれば、テープファスナの固定部が後ウエスト域のウエスト開口近傍に位置しているので、それがクロッチ域側に位置している場合に比して、着用物品を丸めて廃棄するときに、テープファスナを伸展してウエスト開口側へ向かって引っ張り易く、また、テープファスナの長さ寸法が比較的に小さい場合でも丸めた状態を維持することができので、廃棄時の操作性の向上及び資材コストの抑制となる。 According to the disposable wearing article disclosed in Patent Document 1, since the fixing portion of the tape fastener is located in the vicinity of the waist opening of the rear waist region, it is worn compared to the case where it is located on the crotch region side. When the article is rolled up and discarded, it is easy to stretch the tape fastener and pull it toward the waist opening side, and it is possible to maintain the rounded state even when the length of the tape fastener is relatively small. This improves operability during disposal and reduces material costs.

しかし、テープファスナの固定部はシート部材のみから形成された領域に配置されていることから変形し易く、廃棄時にテープファスナを伸展して丸めたおむつを締め付けるときに、固定部が捩れたり変形したりして安定的に丸めた状態を維持したまま廃棄することができない。また、テープファスナの固定部が着用者の身体に密着される後ウエスト域のウエスト開口近傍に位置することによって、比較的に硬質のプラスチック材料から形成されたテープファスナの固定部の先端が身体に間接的に当接し、不快感や刺激を与えるおそれがある。特に、比較的に刺激に弱い肌を有する乳幼児の場合には、かかる刺激等が肌トラブルを引き起こすおそれがある。 However, the fixing part of the tape fastener is easily deformed because it is arranged in the area formed only from the sheet member, and the fixing part is twisted or deformed when the tape fastener is extended and the rolled diaper is tightened at the time of disposal. In other words, it cannot be discarded while maintaining a stable rounded state. In addition, since the fixing portion of the tape fastener is positioned in the vicinity of the waist opening of the rear waist region where the fixing portion of the tape fastener is in close contact with the wearer's body, the tip of the fixing portion of the tape fastener formed from a relatively hard plastic material is attached to the body. There is a risk of indirect contact and discomfort and irritation. In particular, in the case of an infant having skin that is relatively sensitive to irritation, such irritation may cause skin troubles.

そこで、本発明の課題は、操作性に優れ、かつ、着用者の身体を刺激するおそれのないテープファスナを備えた使い捨て着用物品の提供に関する。 Then, the subject of this invention is related with provision of the disposable wear article provided with the tape fastener which is excellent in operativity and does not have a possibility of irritation | stimulating a wearer's body.

Non-elastic regions 34, 35 are defined. As a method of forming the non-elastic region (the same applies to the non-elastic region 35) 34, for example, a second waist elastic body 32 extending in the lateral direction X along the inner end edge 20a is disposed, and the non-elastic region 34 is formed. When the second waist elastic body 32 is fixed with a hot melt adhesive except for the central portion corresponding to, and the second waist elastic body 32 located at the central portion is cut, the second waist elastic body 32 automatically contracts (snaps back), The second waist elastic body 32 having a contracting force is not substantially present in the central portion, and an inelastic region 34 is formed.

前ウエスト域１６においては、第２ウエスト弾性体３２は吸液構造体１５の両側部と交差しており、第２ウエスト弾性体３２の収縮力によって吸液構造体１５が着用者の身体にフィットするので、着用者の大腿部の動きによっても体液の漏れを誘発するような隙間が身体と吸液構造体１５との間に形成されるおそれはない。一方、後ウエスト域１７においては、第２ウエスト弾性体３２が吸液構造体１５と交差しておらず、その収縮力が吸液構造体１５に作用して吸収された体液の漏れの原因となるようなギャザーを生じさせるおそれはない。 In the front waist region 16, the second waist elastic body 32 intersects both sides of the liquid absorption structure 15, and the liquid absorption structure 15 fits the wearer's body by the contraction force of the second waist elastic body 32. Therefore, there is no possibility that a gap that induces leakage of body fluid is formed between the body and the liquid absorption structure 15 even by movement of the thigh of the wearer. On the other hand, in the rear waist region 17, the second waist elastic body 32 does not intersect the liquid absorbing structure 15, and the contraction force acts on the liquid absorbing structure 15 to cause leakage of the absorbed body fluid. There is no risk of such gathering.

Various known fiber nonwoven fabrics or plastic films can be used for the crotch inner and outer layers 36 and 37. Since the crotch inner layer 36 is located facing the liquid absorbing structure 15, it is preferably formed from a leak-proof plastic film, and the crotch outer layer 37 constitutes a part of the outer surface of the diaper 10. It is preferable to form it from a fiber nonwoven fabric that is soft to the touch.

クロッチパネル１４は、前後端部１４ａ，１４ｂと、前後端部１４ａ，１４ｂ間に位置する中間部１４ｃとを有する。前後端部１４ａ，１４ｂは、その非肌対向面側に位置する、ホットメルト接着剤を塗布してなる接合域を介して前後弾性ウエストパネル２０，２１の内端縁２０ａ，２１ａ近傍の肌対向面に固定される。 The crotch panel 14 has front and rear end portions 14a and 14b and an intermediate portion 14c located between the front and rear end portions 14a and 14b. The front and rear end portions 14a and 14b are opposed to the skin in the vicinity of the inner end edges 20a and 21a of the front and rear elastic waist panels 20 and 21 via a joining region formed by applying a hot melt adhesive located on the non-skin facing surface side. Fixed to the surface.

＜レッグ弾性化シート＞
レッグ弾性化シート３５は、ベースシート３４の両側縁部に２つ折りに状態で固定されたサイドシート３８と、サイドシート３８に伸長下に伸縮可能に固定された縦方向Ｙへ延びるレッグ弾性体３９とから構成される。レッグ弾性化シート３５は、ホットメルト接着剤を塗布した接合部４０を介してベースシート３４に固定される。 <Leg elasticized sheet>
The leg elasticization sheet 35 includes a side sheet 38 fixed in a folded state to both side edges of the base sheet 34, and a leg elastic body 39 extending in the longitudinal direction Y fixed to the side sheet 38 so as to be stretchable under expansion. It consists of. The leg elasticization sheet 35 is fixed to the base sheet 34 through a joint 40 to which a hot melt adhesive is applied.

＜吸液構造体＞
図２及び３を参照すると、吸液構造体１５は、縦長のパッド形状を有し、前後端部１５ａ，１５ｂと、中間部１５ｃと、少なくともクロッチ域１８において縦方向Ｙへ延びる吸収性コア４２と、吸収性コア４２の肌対向面側に位置する身体側ライナ４３と吸収性コア４２の非肌対向面側に位置する防漏シート４４とを含む。吸液構造体１５には、その非肌対向面のほぼ全体にホットメルト接着剤が公知のパターンで塗布されている。前後端部１５ａ，１５ｂは、それぞれ、該ホットメルト接着剤を介して前後ウエストパネル２０，２１に固定されており、中間部１５ｃは該ホットメルト接着剤を介してクロッチパネル１４の対向面に固定される。 <Liquid absorption structure>
Referring to FIGS. 2 and 3, the liquid absorbing structure 15 has a vertically long pad shape, front and rear end portions 15 a and 15 b, an intermediate portion 15 c, and an absorbent core 42 extending in the vertical direction Y at least in the crotch region 18. And a body-side liner 43 positioned on the skin facing surface side of the absorbent core 42 and a leak-proof sheet 44 positioned on the non-skin facing surface side of the absorbent core 42. A hot melt adhesive is applied to the liquid absorbing structure 15 in a known pattern over almost the entire non-skin facing surface. The front and rear end portions 15a and 15b are respectively fixed to the front and rear waist panels 20 and 21 via the hot melt adhesive, and the intermediate portion 15c is fixed to the opposing surface of the crotch panel 14 via the hot melt adhesive.

図３に示すとおり、吸液構造体１５の前端部１５ａは、前ウエストパネル２０のウエスト内層２５の肌対向面に固定されており、後端部１５ｂは、後ウエストパネル２１のウエスト内層２６とウエスト外層２８との間においてウエスト外層２８に固定される。吸液構造体１５の前端部１５ａがウエスト内層２５の肌対向面に固定されることによって、着用者の肌には、伸縮弾性を有する比較的に柔軟なウエスト内層２５が直接触れるので、肌触りが向上する。また、後端部１５ｂがウエスト内層２６とウエスト外層２８との間に固定されることから、排泄された体液が拡散してクロッチ域１８から後ウエスト域１７に位置する吸液構造体１５まで浸透しても、体液が直接着用者の肌に触れるのを防止することができる。 As shown in FIG. 3, the front end 15 a of the liquid absorbing structure 15 is fixed to the skin-facing surface of the waist inner layer 25 of the front waist panel 20, and the rear end 15 b is connected to the waist inner layer 26 of the rear waist panel 21. It fixes to the waist outer layer 28 between the waist outer layers 28. Since the front end portion 15a of the liquid-absorbing structure 15 is fixed to the skin-facing surface of the waist inner layer 25, the wearer's skin is directly touched by the relatively flexible waist inner layer 25 having expansion and contraction elasticity. improves. Further, since the rear end portion 15 b is fixed between the waist inner layer 26 and the waist outer layer 28, the excreted body fluid diffuses and penetrates from the crotch region 18 to the liquid absorbing structure 15 located in the rear waist region 17. Even so, the body fluid can be prevented from directly touching the wearer's skin.

吸収性コア４２は、フラッフパルプと、超吸収性ポリマー粒子（ＳＡＰ）との混合から形成された芯材と、液透過性の繊維不織布とから構成される。身体側ライナ４３には、質量約１０〜３０ｇ／ｍ^２の透液性のスパンボンド不織布やＳＭＳ不織布等の各種公知の繊維不織布を用いることができる。防漏シート４４には、質量約１０〜３０ｇ／ｍ^２の不透液性のスパンボンド不織布、ＳＭＳ不織布、プラスチックシートまたは繊維不織布とプラスチックシートとのラミネートシート等を用いることができる。身体側ライナ４３と防漏シート４４とは、吸収性コア４２の周縁から外方へ延出して互いに固定されており、サイドフラップとエンドフラップ４６が形成される。 The absorbent core 42 is composed of a core material formed by mixing fluff pulp and superabsorbent polymer particles (SAP), and a liquid-permeable fiber nonwoven fabric. For the body side liner 43, various known fiber nonwoven fabrics such as a liquid-permeable spunbond nonwoven fabric and SMS nonwoven fabric having a mass of about 10 to 30 g / m ² can be used. As the leak-proof sheet 44, a liquid-impervious spunbond nonwoven fabric having a mass of about 10 to 30 g / m ² , an SMS nonwoven fabric, a plastic sheet, a laminate sheet of a fiber nonwoven fabric and a plastic sheet, or the like can be used.

＜テープファスナ＞
図４を参照すると、テープファスナ１２は、縦軸Ｐに沿って縦方向Ｙへ延びており、その長さ方向において対向する固定端１２ａ及び自由端１２ｂとを有する断面Ｚ字型に折り畳まれた一枚のテープである基材シート５０を含む。基材シート５０には、表面が平滑性を有する、比較的剛性の高いクラフト紙やプラスチックフィルム、それらのラミネートや比較的に質量の高い繊維不織布、例えば、質量約５０ｇ／ｍ^２以上の繊維不織布を好適に使用することができる。テープファスナ１２は、さらに、接合域５１を介して後ウエスト域１６の外面に固定された固定部５２と、固定部５２から連続的に延びる自由部５３とを有する。固定部５２は、縦方向Ｙ内側に位置する内端（固定端）１２ａと、テープファスナ１２の長さ方向において内端１２ｂと対向して位置する外端５２ｂとを有する。テープファスナ１２を形成する基材シート５０として、１本ではなく複数のテープを連結したものを用いることもできる。 <Tape fastener>
Referring to FIG. 4, the tape fastener 12 extends in the longitudinal direction Y along the longitudinal axis P, and is folded into a Z-shaped cross section having a fixed end 12a and a free end 12b facing each other in the length direction. A base sheet 50 that is a single tape is included. The base sheet 50 has a smooth surface with relatively high rigidity, such as kraft paper and plastic film, laminates thereof, and fiber nonwoven fabrics having a relatively high mass, such as fiber nonwoven fabrics having a mass of about 50 g / m ² or more. Can be preferably used. The tape fastener 12 further includes a fixing portion 52 fixed to the outer surface of the rear waist region 16 via the joining region 51 and a free portion 53 that continuously extends from the fixing portion 52. The fixing portion 52 has an inner end (fixed end) 12 a located inside the vertical direction Y, and an outer end 52 b located facing the inner end 12 b in the length direction of the tape fastener 12. As the base material sheet 50 for forming the tape fastener 12, it is possible to use not only one but also a plurality of tapes connected to each other.

テープファスナ１２の自由部５３は、固定部５２と連なりそれとテープファスナ１２の厚さ方向Ｚにおいて対向する第１自由部５４と、第１自由部５４と連なりそれと厚さ方向Ｚにおいて対向する第２自由部５５とを有する。固定部５２と第１自由部５４とは、互いの対向面のうちのいずれか一方に塗布された感圧性接着剤からなる第１止着域５６によって止着されており、第１自由部５４と第２自由部５５とは、互いの対向面のうちのいずれか一方に塗布された感圧性接着剤からなる第２止着域（掛け止め域）５７によって止着されており、第１及び第２止着域５６，５７の止着によって積層された状態が維持されている。第２自由部５４において、第２止着域５７は自由端１２ｂまで延びておらず、第２止着域５４から自由端１２ｂ側の領域において摘持部５９が形成される。摘持部５９の視認性を向上させるために、基材シート５０の摘持部５９に相当する部分に直接着色したり又は該部分に有色の別体のシートを貼付してもよい。第１及び第２止着域には、繰り返し止着可能な感圧性接着剤や粘着剤のほかに、面ファスナのフック部材を配置してもよい。また、テープファスナ１２の表面が繊維不織布から形成される場合には、積層された各領域をエンボスピン等によって仮止めしてもよい。 The free part 53 of the tape fastener 12 is connected to the fixed part 52 and faces the first free part 54 in the thickness direction Z of the tape fastener 12, and the second free part 53 is connected to the first free part 54 and faces the second part 54 in the thickness direction Z. And a free part 55. The fixed portion 52 and the first free portion 54 are fixed by a first fixing region 56 made of a pressure-sensitive adhesive applied to one of the opposing surfaces. And the second free portion 55 are fastened by a second fastening region (hanging region) 57 made of a pressure-sensitive adhesive applied to any one of the opposing surfaces. The stacked state is maintained by the fastening of the second fastening areas 56 and 57. In the second free portion 54, the second fastening region 57 does not extend to the free end 12b, and a gripping portion 59 is formed in a region on the free end 12b side from the second fastening region 54. In order to improve the visibility of the gripping portion 59, a portion corresponding to the gripping portion 59 of the base sheet 50 may be colored directly, or a colored separate sheet may be attached to the portion. In the first and second fastening regions, hook members of hook-and-loop fasteners may be disposed in addition to the pressure-sensitive adhesive and pressure-sensitive adhesive that can be repeatedly fastened. Moreover, when the surface of the tape fastener 12 is formed from a fiber nonwoven fabric, each laminated | stacked area | region may be temporarily fixed by embossed spin etc.

図５を参照すると、テープファスナ１２の固定部５２は、内端５２ａが吸液構造体１５の存在する領域に位置し、外端５２ｂが吸液構造体１５よりも縦方向Ｙの外側に位置する後ウエストパネル２１上に位置している。テープファスナ１２は、廃棄時において、おむつ１０を丸めてウエスト開口２３に向かって伸展して使用するものであるから、操作性及びその長さ寸法を有効活用することを考慮すれば、固定部５２は、後ウエスト域１７のうちのウエスト開口２３寄りに位置していることが好ましい。本実施形態の場合には、固定部５２の外端５２ｂが吸液構造体１５の外端縁よりも縦方向Ｙの外側に位置し、ウエスト開口２３寄りに位置しているので、固定部５２全体が吸液構造体１５と重なってクロッチ域１８側に位置する場合に比して、廃棄時の操作性に優れる。また、比較的に剛性の高い吸液構造体１５の近傍に位置する固定部５２の外端５２ｂにはテープファスナ１２を丸めたおむつに掛け回したときに力が集中しやすくそれを剥離しようとする力が加えられるところ、テープファスナ１２をその力を分散できる程度に比較的に低い剛性のシートで形成し、かつ、ウエスト内層２６による伸縮性を利用することによって、かかる力を分散できる。したがって、ウエスト内層２６の伸長力を利用して十分にテープファスナ１２を引っ張った状態のまま締め付けることができ、止着したテープファスナ１２が不容易に外れてしまうおそれはない。一方、テープファスナ１２が比較的に高剛性の吸液構造体１５上に位置することによって、固定部５２は安定的に後ウエスト域１７の外面に取り付けられ、おむつ１０を丸めて廃棄するときに、固定部５２が変形して丸めた状態が崩れたりするおそれはない。 Referring to FIG. 5, the fixing portion 52 of the tape fastener 12 has an inner end 52 a positioned in a region where the liquid absorbing structure 15 exists and an outer end 52 b positioned outside the liquid absorbing structure 15 in the longitudinal direction Y. It is located on the rear waist panel 21. Since the tape fastener 12 is used when the diaper 10 is rolled up and extended toward the waist opening 23 at the time of disposal, considering the operability and effective use of its length, the fixing portion 52 is used. Is preferably located near the waist opening 23 in the rear waist region 17. In the case of the present embodiment, the outer end 52b of the fixing portion 52 is located on the outer side in the vertical direction Y with respect to the outer edge of the liquid absorbing structure 15, and is located closer to the waist opening 23. Compared with the case where the entire structure overlaps with the liquid absorbing structure 15 and is located on the crotch region 18 side, the operability at the time of disposal is excellent. Further, when the tape fastener 12 is hung around a rolled diaper, the force tends to concentrate on the outer end 52b of the fixing portion 52 located in the vicinity of the relatively high-absorbent liquid-absorbing structure 15. When the force to apply is applied, the tape fastener 12 is formed of a sheet having a relatively low rigidity so that the force can be dispersed, and the stretchability of the waist inner layer 26 is utilized to disperse the force. Therefore, the tape fastener 12 can be tightened in a state where the tape fastener 12 is sufficiently pulled using the extension force of the waist inner layer 26, and there is no possibility that the fastened tape fastener 12 may be easily detached. On the other hand, when the tape fastener 12 is positioned on the relatively high-rigidity liquid absorbing structure 15, the fixing portion 52 is stably attached to the outer surface of the rear waist region 17, and the diaper 10 is rolled up and discarded. There is no possibility that the fixed portion 52 is deformed and the rolled state is not collapsed.

図６を参照すると、このように、テープファスナ１２を吸液構造体１５上に配置した場合には、テープファスナ１２が湾曲状を呈し、固定部５２の外端５２ｂ近傍が着用者の身体へ向かって延びる。テープファスナ１２は、おむつ１０を構成する繊維不織布シートから形成された他のシート部材に比して比較的に高剛性のシート部材から形成されており、その一部が後ウエストパネル２１を構成するシート部材を介して間接的に着用者の肌に触れる場合であっても、痛みや不快感等の刺激を与えかねない。特に、着用者が比較的に肌の弱い乳幼児の場合には、その刺激によって肌トラブルを生じ易い。したがって、例えば、吸液構造体１５がその外側に位置するウエスト弾性体等の伸長応力によって着用者の身体側へ押しつけられた場合には、固定部５２の外端５２ｂが着用者の腰部の肌に間接的に触れて肌を刺激するおそれがある。本実施形態におけるおむつ１０の場合には、ウエスト内層２６が吸液構造体１５の内側に位置していることから吸液構造体１５が着用者の身体側に向かって押し付けられることはなく、かかる事態が生じるおそれはない。 Referring to FIG. 6, when the tape fastener 12 is arranged on the liquid absorbing structure 15 as described above, the tape fastener 12 has a curved shape, and the vicinity of the outer end 52 b of the fixing portion 52 is directed to the wearer's body. Extend toward. The tape fastener 12 is formed from a sheet member having a relatively high rigidity as compared with other sheet members formed from the fiber nonwoven sheet constituting the diaper 10, and a part thereof forms the rear waist panel 21. Even when the skin of the wearer is indirectly touched through the sheet member, it may cause irritation such as pain and discomfort. In particular, when the wearer is an infant with relatively weak skin, skin irritation is likely to occur due to the stimulation. Therefore, for example, when the liquid absorption structure 15 is pressed against the wearer's body side by an elongation stress such as a waist elastic body positioned outside the skin, the outer end 52b of the fixing portion 52 is the skin of the wearer's waist. May cause irritation by touching the skin indirectly. In the case of the diaper 10 according to the present embodiment, since the waist inner layer 26 is located inside the liquid absorbing structure 15, the liquid absorbing structure 15 is not pressed toward the wearer's body side. There is no risk of a situation.

図７（ａ）を参照すると、おむつ１０の着用状態において、後ウエスト域１７の伸縮性を有するウエスト内層２６は、吸液構造体１５の内側に位置していることによって、着用者の身体に密接している。ウエスト内層２６が伸縮性のシートから形成される一方、ウエスト外層２８は非伸縮性のシートから形成されていることから、ウエスト内層２６が収縮してその横方向Ｘの長さ寸法が小さくなることによって、それに固定されたウエスト外層２８の横方向Ｘの寸法も小さくなる。ウエスト外層２８の横方向Ｘが小さくなりその縮められた寸法分が比較的に剛性の高い吸液構造体１５の両側縁部１５ｄに集中して、その内側に巻き込まれるように折れ曲がる。 Referring to FIG. 7 (a), in the wearing state of the diaper 10, the waist inner layer 26 having elasticity of the rear waist region 17 is positioned on the inner side of the liquid absorbing structure 15, so that the wearer's body Close. While the waist inner layer 26 is formed of a stretchable sheet, the waist outer layer 28 is formed of a non-stretchable sheet, so that the waist inner layer 26 contracts and the length dimension in the lateral direction X decreases. Thus, the dimension in the lateral direction X of the waist outer layer 28 fixed thereto is also reduced. The lateral direction X of the waist outer layer 28 is reduced, and the contracted dimension is concentrated on both side edges 15d of the liquid absorbing structure 15 having relatively high rigidity, and is bent so as to be wound inside.

図７（ｂ）を参照すると、吸液構造体１５は、着用者の身体の動きに応じてウエスト回り方向へ伸長及び／又は収縮を繰り返すウエスト内層２６の動きに合わせて、その側縁部１５ｄの内側に入り込んだウエスト外層２８の一部を基端部４５として、仮想線で示す着用者の身体から離間したような状態となって横方向Ｘへ揺動する。また、おむつ１０を穿いたまま下着等の着衣を着用した場合において、吸液構造体１５が着用者の身体に向かって押し付けられたときに、基端部４５ａ，４５ｂが吸液構造体１５に加えられた力を緩衝する。 Referring to FIG. 7 (b), the liquid absorbing structure 15 has its side edge 15d in accordance with the movement of the waist inner layer 26 that repeatedly expands and / or contracts in the direction around the waist according to the movement of the wearer's body. A portion of the outer waist layer 28 that has entered the inside of the base is made into a state of being separated from the wearer's body indicated by an imaginary line as a base end portion 45 and swings in the lateral direction X. In addition, when wearing clothing such as underwear while wearing the diaper 10, when the liquid absorbing structure 15 is pressed against the wearer's body, the base end portions 45 a and 45 b are attached to the liquid absorbing structure 15. Buffer applied force.

従って、着用者の背中の動き等によってテープファスナ１２の固定部５２の外端５２ｂに対してそれを着用者の身体に食い込むように作用する力Ｆが加えられた場合において、吸液構造体１５の側縁部１５ｄの内側に巻きこまれた基端部４５が起立して吸液構造体１５が浮き上がった状態で斜め下方へ僅かに移動し、外端５２ｂに加えられた力Ｆを緩衝する。それによって、外端５２ｂが着用者の身体に向かって食い込むように押し付けられることを抑制し、着用者に不快感等を与えることを回避できる。また、このように吸液構造体１５が横方向Ｘへ揺動することによって外端５２ｂの身体に間接的に当接される位置が固定されず、比較的に長時間同じ箇所に外端５２ｂが身体に当接されることによって生じる肌への刺激や不快感を防ぐことができる。 Therefore, when a force F acting on the outer end 52b of the fixing portion 52 of the tape fastener 12 to bite it into the wearer's body due to movement of the wearer's back or the like is applied, the liquid absorbing structure 15 The base end portion 45 wound inside the side edge portion 15d rises and the liquid absorbing structure 15 is lifted slightly, and moves slightly diagonally downward to buffer the force F applied to the outer end 52b. Accordingly, the outer end 52b can be prevented from being pushed toward the wearer's body, and the wearer can be prevented from feeling uncomfortable. In addition, the position of the outer end 52b that is indirectly in contact with the body is not fixed by swinging the liquid absorbing structure 15 in the lateral direction X in this manner, and the outer end 52b is kept at the same place for a relatively long time. Can prevent irritation and discomfort to the skin caused by contact with the body.

かかる効果を高めるために、ウエスト内層２６は、吸液構造体１５に固定されておらず、ウエスト外層２８にのみ固定されていてもよい。かかる場合には、吸液構造体１５がより着用者の身体の動きに追従して揺動し、外端５２ｂが着用者の身体の同じ箇所に当接するのを防止できるからである。また、ウエスト外層２８のテープファスナ１２の固定部５２の外端５２ｂが位置する領域には、ウエスト内層２６の収縮作用によって複数の皺が形成されているので、該領域のクッション性が向上し、外端５２ｂによる着用者の肌に対する刺激が低減される。また、ウエスト外層２８として、例えば、少なくともその外面が捲縮繊維を含む繊維不織布から形成される場合には、外面がより嵩高になってクッション性に優れるので、テープファスナ１２が身体に当接することによる肌に対する刺激を抑えることができる。捲縮繊維としては、２次元的に捲縮する波状、３次元的に捲縮するコイル又はスパイラル状等の各種の捲縮形態を有するものを用いることができ、特に、ポリプロピレンを鞘、エチレン・プロピレンのコポリマーを芯とする偏芯鞘型に係る熱収縮捲縮法によって得られる複合繊維を用いることが、所望の捲縮数、捲縮率、捲縮伸長率、捲縮復元率などのうえで好ましい。さらに、クッション性及び嵩高性を高めるために、捲縮繊維を含むウエスト外層２８の外面にキルト模様等を施してもよい。 In order to enhance this effect, the waist inner layer 26 may not be fixed to the liquid absorbing structure 15 but may be fixed only to the waist outer layer 28. In such a case, it is possible to prevent the liquid absorbing structure 15 from swinging following the movement of the wearer's body and preventing the outer end 52b from coming into contact with the same portion of the wearer's body. In addition, in the region where the outer end 52b of the fixing portion 52 of the tape fastener 12 of the waist outer layer 28 is located, a plurality of wrinkles are formed by the contraction action of the waist inner layer 26, so that the cushioning property of the region is improved. The irritation | stimulation with respect to a wearer's skin by the outer end 52b is reduced. Further, as the waist outer layer 28, for example, when at least the outer surface is formed of a fiber nonwoven fabric containing crimped fibers, the outer surface becomes more bulky and excellent in cushioning properties, so that the tape fastener 12 contacts the body. Can suppress irritation to the skin. As the crimped fibers, those having various crimped forms such as a two-dimensional crimped wave, a three-dimensional crimped coil or a spiral can be used. Using a composite fiber obtained by a heat shrinkage crimping method relating to an eccentric sheath type having a propylene copolymer as a core, in addition to a desired number of crimps, crimp rate, crimp extension rate, crimp recovery rate, etc. Is preferable. Furthermore, in order to improve cushioning properties and bulkiness, a quilt pattern or the like may be applied to the outer surface of the waist outer layer 28 including crimped fibers.

テープファスナ１２の固定部５２は、内端５２ａから外端５２ｂに向かって吸収性コア４２の存在域からエンドフラップ４６を通過してグラフィック表示シート３０上にまで延びていて、積層されたシート部材の枚数が次第に減少することによって、縦方向Ｙの内側から外側へ向かって次第になだらかに傾斜している。これによって、テープファスナ１２の固定部５２に大きな段差が設けられることはなく、急な傾斜によって外端５２ｂが身体に向かって食い込むように斜めに延びることはない。既述の本願発明の効果を奏する限りにおいて、テープファスナ１２は、その内端が吸液構造体１５の存在域に位置し、外端が吸液構造体１５の外端縁よりもウエスト開口側に位置していればよく、例えば、固定部５２の固定端（内端）１２ａが吸液構造体１５の存在域に位置し、後ウエスト域１７の外面に剥離可能に固定された自由端（外端）１２ｂが吸液構造体１５の端縁よりもウエスト開口２３側に位置する態様等を含む。 The fixing portion 52 of the tape fastener 12 extends from the inner end 52a toward the outer end 52b from the region where the absorbent core 42 exists through the end flap 46 and onto the graphic display sheet 30, and is a laminated sheet member. As the number of sheets gradually decreases, the vertical direction Y is gradually inclined from the inside toward the outside. As a result, a large step is not provided in the fixing portion 52 of the tape fastener 12, and the outer end 52b does not extend obliquely so as to bite into the body due to a steep inclination. As long as the effects of the present invention described above are exhibited, the tape fastener 12 has an inner end located in the region where the liquid absorbing structure 15 is present, and an outer end that is closer to the waist opening side than the outer end edge of the liquid absorbing structure 15. For example, the fixed end (inner end) 12a of the fixing portion 52 is positioned in the region where the liquid absorbing structure 15 is present, and is fixed to the outer surface of the rear waist region 17 so as to be peelable ( The outer end) 12 b includes a mode in which the outer edge 12 b is positioned closer to the waist opening 23 than the edge of the liquid absorbing structure 15.

図８を参照すると、おむつ１０を廃棄する態様の一例が示されており、まず、おむつ１０の使用後に、サイドシーム２２を剥離して前後ウエスト域１６，１７の両側縁部を離間させ、該両側縁部を内側へ折り曲げ、クロッチ域１８を前後ウエスト域１６，１７に向かって丸め込むように折り曲げる。次に、テープファスナ１２の自由部５３を掛け止め域５７を介してクロッチ域１８の外面に掛け止める。これにより、おむつ１０を丸めた状態を保持することができ、排泄物を外部に漏らすことなく、衛生的に廃棄することができる。しかし、例えば、テープファスナ１２の固定部５２全体が吸液構造体１５上に位置する場合には、吸液構造体１５全体を巻き込んでテープファスナ１２で締め付けることができず、固定部５２よりもウエスト開口２３側に位置する吸液構造体１５に吸収された体液がウエスト開口２３から外部に漏れ出るおそれがある。本実施形態にかかるおむつ１０においては、テープファスナ１２の固定部５２の外端５２ｂが吸液構造体１５よりもウエスト開口２４側に位置しているので、テープファスナ１２を伸展して吸液構造体１５全体を巻き込んだ状態で丸めたおむつ１０を締め付けることができ、吸液構造体１５の端部に吸収された体液が外部に漏れるのを妨げることができる。 Referring to FIG. 8, an example of an aspect of discarding the diaper 10 is shown. First, after use of the diaper 10, the side seams 22 are peeled to separate both side edges of the front and rear waist regions 16, 17, Both side edges are bent inward, and the crotch region 18 is bent so as to be rounded toward the front and rear waist regions 16 and 17. Next, the free portion 53 of the tape fastener 12 is latched to the outer surface of the crotch region 18 via the latching region 57. Thereby, the state which rolled the diaper 10 can be hold | maintained, and it can dispose hygienically without leaking excrement outside. However, for example, when the entire fixing portion 52 of the tape fastener 12 is located on the liquid absorbing structure 15, the entire liquid absorbing structure 15 cannot be wound and tightened with the tape fastener 12, and the fixing portion 52 can be tightened. There is a risk that body fluid absorbed by the liquid absorbing structure 15 located on the side of the waist opening 23 may leak out from the waist opening 23. In the diaper 10 according to the present embodiment, the outer end 52b of the fixing portion 52 of the tape fastener 12 is located on the side of the waist opening 24 relative to the liquid absorbing structure 15, so that the tape fastener 12 is extended to absorb the liquid. The rolled diaper 10 can be tightened in a state where the entire body 15 is rolled up, and the body fluid absorbed by the end of the liquid absorbing structure 15 can be prevented from leaking to the outside.
