Description

使い捨て着用物品Disposable wearing items
　本発明は、使い捨て着用物品に関する。 The present invention relates to a disposable wearing article.
　従来、使い捨ての着用物品は公知である。例えば、特許文献１には、吸収体と、吸収体の横方向両側縁から外側へ延出し複数本の脚回り弾性部材を有するサイドフラップと、サイドフラップ上の吸収体側縁に沿って長手方向に配置される防漏カフスとを有する使い捨ておむつにおいて、防漏カフスはサイドフラップの複数本の脚回り弾性部材の間に起立線を有しており、防漏カフスの起立線の内側に１本以上の脚回り弾性部材を配置することにより股下部分の防漏カフスの堰を高くした使い捨ておむつが開示されている。 Conventionally, disposable wearing articles are known. For example, Patent Document 1 discloses that an absorbent body, a side flap having a plurality of leg-hole elastic members extending outward from both lateral edges of the absorbent body, and a longitudinal side along the absorbent side edge on the side flap. In a disposable diaper having a leak-proof cuff arranged, the leak-proof cuff has a standing line between a plurality of leg-hole elastic members of the side flap, and one or more are provided inside the standing line of the leak-proof cuff. Disposable diapers are disclosed in which the weirs of the cuffs at the crotch portion are raised by arranging the elastic members around the legs.
特開平１０－７５９７６号公報Japanese Patent Laid-Open No. 10-75976
　特許文献１に開示された発明によれば、防漏カフスの起立線の内側に１本以上の脚回り弾性部材を配置することにより、脚回り弾性部材の弾性収縮力で防漏カフスが立ち上がりやすくなり、防漏カフスの堰が高くなる結果、防漏カフスで形成するポケット構造の容量が大きくなり、漏れが防止される。 According to the invention disclosed in Patent Document 1, by disposing one or more leg-hole elastic members inside the standing line of the leak-proof cuff, the leak-proof cuff can easily rise due to the elastic contraction force of the leg-hole elastic member. As a result, the height of the weir of the leak-proof cuff is increased, so that the capacity of the pocket structure formed by the leak-proof cuff increases and leakage is prevented.
　しかし、特許文献１の使い捨ておむつでは、おむつの脚回りを着用者の脚にフィットさせるためにサイドフラップに設けられた複数本の脚回り弾性部材も防漏カフスとともに起立する。本来、サイドフラップに設けられ複数本の脚回り弾性部材は、防漏カフスとは異なる場所で着用者の脚にフィットして漏れを防ぐためのものである。しかし、特許文献１の場合、サイドフラップに設けられ複数本の脚回り弾性部材と防漏カフスとがともに立ち上がって互いに重なり合う結果、着用者の脚に同じ場所でフィットすることがある。また、サイドフラップに設けられ複数本の脚回り弾性部材と防漏カフスとがともに立ち上がったとき、防漏カフスが吸収体に対しほぼ垂直になり、防漏カフスにより形成される堰は高くなるものの、良好な形状のポケット構造は形成されないという問題もあり、未だ改良の余地がある。 However, in the disposable diaper of Patent Document 1, a plurality of leg-hole elastic members provided on the side flaps to stand together with the leak-proof cuffs in order to fit the leg circumference of the diaper to the wearer's leg. Originally, the plurality of leg-hole elastic members provided on the side flaps are for fitting to the wearer's leg at a place different from the leak-proof cuff and preventing leakage. However, in the case of Patent Document 1, a plurality of leg-hole elastic members and leak-proof cuffs, which are provided on the side flaps, rise together and overlap each other, so that they may fit the wearer's leg at the same place. In addition, when a plurality of leg-hole elastic members provided on the side flaps and the leak-proof cuff stand together, the leak-proof cuff becomes almost perpendicular to the absorber, and the weir formed by the leak-proof cuff becomes high. However, there is a problem that a well-shaped pocket structure is not formed, and there is still room for improvement.
　以上に鑑み、本発明は、着用時にサイドフラップに設けられた複数本の脚回り弾性部材と防漏カフ部とが重なり合うことが無く、安定的にポケット構造が形成される使い捨て着用物品を提供することを課題とする。 In view of the above, the present invention provides a disposable wearing article in which a plurality of leg-holes elastic members provided on a side flap at the time of wearing and a leak-proof cuff portion do not overlap and a pocket structure is stably formed.

The leak-proof cuff portion 42 includes a free edge 42c that is spaced apart from the branch line 41 and extends in the vertical direction Y, and a leak-proof cuff elastic member 45 that extends in the vertical direction Y along the free edge 42c. A leak-proof cuff front end 42a and a leak-proof cuff rear end 42b are located at both ends in the longitudinal direction Y of the leak-proof cuff 42, respectively. The leakproof cuff front and rear end portions 42a and 42b are joined to the skin facing surfaces of the front and rear waist panels 16 and 17, respectively. The leg elastic portion 43 includes a leg-hole elastic member 46 extending in the longitudinal direction Y between the branch line 41 and the side flap distal edge 40c. A leg elastic portion front end portion 43a and a leg elastic portion rear end portion 43b are located at both ends in the longitudinal direction Y of the leg elastic portion 43, respectively. The leg elastic portion front and rear end portions 43a and 43b are fixed to the skin facing surfaces of the front and rear waist panels 16 and 17, respectively. The side flap front end portion 40a includes a leakproof cuff front end portion 42a and a leg elastic portion front end portion 43a, and the side flap rear end portion 40b includes a leakproof cuff rear end portion 42b and a leg elastic portion rear end portion 43b.
　防漏カフ部４２とレッグ弾性部４３は、サイドフラップ４０に含まれる身体側ライナー３０、バックシート３１、及び被覆シート３３を折り返して形成されている。具体的には、レッグ弾性部４３は、サイドフラップ４０に含まれる被覆シート３３を縦方向中心線Ｐに向けて折り返して形成している（図３、図４参照）。また、防漏カフ部４２は、縦方向中心線Ｐに向けて折り返した被覆シート３３の端部３３ａと、縦方向中心線Ｐに向けて折り返したバックシート３１及び身体側ライナー３０とを重ね合わせて形成している。レッグ弾性部４３において分岐線４１とサイドフラップ遠位縁４０ｃとの間で重なり合う被覆シート３３どうしは、接着剤、例えばホットメルト接着剤（図示せず）により互いに固定されている。また、防漏カフ部４２において分岐線４１と自由縁４２ｃとの間で重なり合う被覆シート３３、バックシート３１及び身体側ライナー３０も、接着剤、例えばホットメルト接着剤（図示せず）により互いに接合されている。これにより、防漏カフ部４２とレッグ弾性部４３とは、分岐線４１において接着剤、例えばホットメルト接着剤（図示せず）により互いに固定される。なお、添付の図面では、防漏カフ前後端部４２ａ，４２ｂをサイドフラップ４０の肌対向面に接合するための接着剤、例えばホットメルト接着剤のみを図示している。 The leak-proof cuff part 42 and the leg elastic part 43 are formed by folding back the body side liner 30, the back sheet 31, and the covering sheet 33 included in the side flap 40. Specifically, the leg elastic part 43 is formed by folding the covering sheet 33 included in the side flap 40 toward the longitudinal center line P (see FIGS. 3 and 4). Further, the leak-proof cuff portion 42 overlaps the end portion 33a of the covering sheet 33 folded back toward the longitudinal center line P with the back sheet 31 and the body side liner 30 folded back toward the longitudinal center line P. Formed. The covering sheets 33 that overlap between the branch line 41 and the side flap distal edge 40c in the leg elastic portion 43 are fixed to each other by an adhesive, for example, a hot melt adhesive (not shown). In addition, the covering sheet 33, the back sheet 31, and the body side liner 30 that overlap between the branch line 41 and the free edge 42c in the leak-proof cuff portion 42 are also joined to each other by an adhesive, for example, a hot melt adhesive (not shown). Has been. Thereby, the leak-proof cuff part 42 and the leg elastic part 43 are mutually fixed in the branch line 41 with the adhesive agent, for example, hot-melt-adhesive (not shown). In the attached drawings, only an adhesive for joining the leak-proof cuff front and rear end portions 42a, 42b to the skin facing surface of the side flap 40, for example, a hot melt adhesive is shown.
　吸収体３２の側縁３２ｃに沿って延びる側方弾性部材４７には、繊度が約３００～９４０ｄｔｅｘの１条以上のストランド状の弾性材料を伸長倍率約１．５～３．０倍にして用いることができる。本実施形態では、吸収体３２の横方向Ｘ外側に、７８０ｄｔｅｘの弾性糸１本を、縦方向Ｙに２．２倍伸長させて接合している。側方弾性部材４７は、おむつ１０が着用されたとき、吸収体３２をウエスト開口１８に向けて引き上げ、吸収体３２がずり下がることを防止する。 For the side elastic member 47 extending along the side edge 32c of the absorbent body 32, one or more strand-shaped elastic materials having a fineness of about 300 to 940 dtex are used at an expansion ratio of about 1.5 to 3.0 times. be able to. In this embodiment, one 780 dtex elastic yarn is stretched 2.2 times in the longitudinal direction Y and joined to the outside of the absorbent body 32 in the lateral direction X. When the diaper 10 is worn, the side elastic member 47 pulls up the absorber 32 toward the waist opening 18 and prevents the absorber 32 from sliding down.
　レッグ弾性部４３に配置される脚回り弾性部材４６は、縦方向Ｙに伸長状態で接合される。詳しくは、レッグ弾性部４３は縦方向Ｙに延びるとともに横方向Ｘ寸法が互いに等しい３つのサブ領域４９に区画され、３つのサブ領域４９のそれぞれに、脚回り弾性部材４６が配置されている。脚回り弾性部材４６には、帯状またはストランド状の弾性材料を、約１．５～３．０倍に伸長して用いることができる。ストランド状の弾性材料を用いる場合、繊度が約３００～９４０ｄｔｅｘの弾性糸を用いることが好ましい。本実施形態では、脚回り弾性部材４６として、複数条の弾性糸を用いている。 The leg elastic member 46 disposed in the leg elastic portion 43 is joined in the longitudinal direction Y in an extended state. Specifically, the leg elastic portion 43 is partitioned into three sub-regions 49 that extend in the vertical direction Y and have the same lateral X dimension, and a leg-hole elastic member 46 is disposed in each of the three sub-regions 49. For the leg-hole elastic member 46, a band-like or strand-like elastic material can be used by extending about 1.5 to 3.0 times. When a strand-like elastic material is used, it is preferable to use an elastic yarn having a fineness of about 300 to 940 dtex. In the present embodiment, a plurality of elastic yarns are used as the leg-hole elastic member 46.
　３つのサブ領域４９のそれぞれに配置される脚回り弾性部材４６のうち、分岐線４１に隣接するサブ領域４９に配置される脚回り弾性部材４６の収縮力の方が、遠位縁４０ｃに隣接するサブ領域４９に配置される脚回り弾性部材４６の収縮力よりも大きいことが好ましい。また、各サブ領域４９に配置される脚回り弾性部材４６の伸長倍率をほぼ同じ値にすることが好ましい。これにより、レッグ弾性部４３がレッグ開口１９からおむつ１０の横方向Ｘ外側に向けて筒状に突き出し易くなる。一例を挙げると、レッグ弾性部４３において分岐線４１に隣接するサブ領域４９に、６２０ｄｔｅｘの弾性糸を伸長倍率２．２倍にして２条配置するとともに、遠位縁４０ｃに隣接するサブ領域４９に３１０ｄｔｅｘの弾性糸を伸長倍率２．０～２．２倍にして２条配置し、更にこの２つのサブ領域４９の間に位置するサブ領域４９に、６２０ｄｔｅｘで伸長倍率２．２倍の１条の弾性糸と、３１０ｄｔｅｘで伸長倍率２．０～２．２倍の１条の弾性糸を配置することができる。脚回り弾性部材４６は、被覆シート３３を折り返した内側に接合することができる。脚回り弾性部材４６を複数条のストランド状の弾性材料で構成すれば、レッグ弾性部４３が筒状の蛇腹構造となっておむつ１０のレッグ開口１９から横方向Ｘ外側に向けて突き出して着用者の腿にフィットし易くなる。また、レッグ弾性部４３において分岐線４１に隣接するサブ領域４９に含まれる脚回り弾性部材４６の収縮力を、遠位縁４０ｃに隣接するサブ領域４９に含まれる脚回り弾性部材４６の収縮力よりも大きくすることにより、分岐線４１近傍を着用者の腿に確実にフィットさせることができ、さらに遠位縁４０ｃが着用者の肌を刺激することが防止される。 Of the leg elastic members 46 arranged in each of the three sub-regions 49, the contraction force of the leg elastic members 46 arranged in the sub-region 49 adjacent to the branch line 41 is adjacent to the distal edge 40c. It is preferable that it is larger than the contraction force of the leg-holes elastic member 46 arranged in the sub-region 49 to be operated. Moreover, it is preferable to make the expansion ratio of the leg-holes elastic member 46 arranged in each sub-region 49 substantially the same value. Thereby, the leg elastic part 43 becomes easy to protrude in the cylinder shape toward the lateral direction X outer side of the diaper 10 from the leg opening 19. As an example, in the leg elastic part 43, in the sub-region 49 adjacent to the branch line 41, two 620 dtex elastic yarns are arranged at an expansion ratio of 2.2, and the sub-region 49 adjacent to the distal edge 40c. Two elastic yarns of 310 dtex are arranged at a stretch magnification of 2.0 to 2.2 times, and one sub-region 49 positioned between the two sub-regions 49 is 620 dtex with a stretch magnification of 2.2 times 1 It is possible to dispose a single elastic yarn having a length of elastic yarn of 310 dtex and a stretching magnification of 2.0 to 2.2 times. The leg-hole elastic member 46 can be joined to the inner side where the covering sheet 33 is folded back. If the leg-hole elastic member 46 is made of a plurality of strand-like elastic materials, the leg elastic portion 43 has a cylindrical bellows structure and protrudes outward in the lateral direction X from the leg opening 19 of the diaper 10. It will be easier to fit your thigh. Further, in the leg elastic part 43, the contraction force of the leg elastic member 46 included in the sub-region 49 adjacent to the branch line 41 is used as the contraction force of the leg elastic member 46 included in the sub-region 49 adjacent to the distal edge 40c. By making it larger than this, the vicinity of the branch line 41 can be surely fitted to the wearer's thigh, and the distal edge 40c is prevented from stimulating the wearer's skin.
　分岐線弾性部材４４は、脚回り弾性部材４６と防漏カフ弾性部材４５の間に位置し、防漏カフ部４２の起立基端縁である分岐線４１に隣接して縦方向Ｙに延びる。分岐線弾性部材４４は、おむつ１０が着用されたときに分岐線４１をウエスト開口１８に向けて引き上げ、分岐線４１がずり下がることを防止する。防漏カフ部４２とレッグ弾性部４３との重なり合いを防止するために、分岐線弾性部材４４を、分岐線４１と防漏カフ弾性部材４５との間であって、分岐線４１に接する位置に配置することが好ましい。これにより、防漏カフ部４２がレッグ弾性部４３に向けて倒れることを有効に防止できる。本発明において分岐線弾性部材４４は必須ではなく、省略することもできる。 The branch line elastic member 44 is located between the leg-hole elastic member 46 and the leak-proof cuff elastic member 45 and extends in the longitudinal direction Y adjacent to the branch line 41 that is the standing base edge of the leak-proof cuff part 42. The branch line elastic member 44 pulls up the branch line 41 toward the waist opening 18 when the diaper 10 is worn, and prevents the branch line 41 from sliding down. In order to prevent the leak-proof cuff part 42 and the leg elastic part 43 from overlapping, the branch line elastic member 44 is positioned between the branch line 41 and the leak-proof cuff elastic member 45 and in contact with the branch line 41. It is preferable to arrange. Thereby, it can prevent effectively that the leak-proof cuff part 42 falls toward the leg elastic part 43. FIG. In the present invention, the branch line elastic member 44 is not essential and may be omitted.
　分岐線弾性部材４４には、繊度が約３００～９４０ｄｔｅｘの１条以上のストランド状の弾性材料を、伸長倍率を約１．５～３．０倍にして用いることができる。本実施形態では、７８０ｄｔｅｘの弾性糸を伸長倍率２．２倍で縦方向Ｙに伸長させ、この弾性糸に接着剤、例えばホットメルト接着剤（図示せず）を塗布して、防漏カフ部４２に含まれる被覆シート３３及びバックシート３１との間に固定している。図３～５に示すように、本実施形態では、平面視において分岐線４１の位置と分岐線弾性部材４４の位置とがほぼ一致している。別言すれば、分岐線弾性部材４４に塗布された接着剤、例えばホットメルト接着剤を介して、防漏カフ部４２とレッグ弾性部４３とが固定されている。これに代えて、レッグ弾性部４３と防漏カフ部４２との境界に位置する被覆シート３３と、防漏カフ部４２に含まれるバックシート３１とを接着剤、例えばホットメルト接着剤で接合して分岐線４１とすることによって、防漏カフ部４２とレッグ弾性部４３とを分岐線４１において固定することができる。この場合、分岐線４１と防漏カフ弾性部材４５との間であって分岐線４１に隣接する位置に分岐線弾性部材４４を配置し、防漏カフ部４２に固定する。 For the branch line elastic member 44, one or more strand-shaped elastic materials having a fineness of about 300 to 940 dtex can be used with an expansion ratio of about 1.5 to 3.0 times. In this embodiment, an elastic yarn of 780 dtex is elongated in the longitudinal direction Y at an elongation ratio of 2.2 times, and an adhesive, for example, a hot melt adhesive (not shown) is applied to the elastic yarn, and a leak-proof cuff portion It is fixed between the covering sheet 33 and the back sheet 31 included in 42. As shown in FIGS. 3 to 5, in the present embodiment, the position of the branch line 41 and the position of the branch line elastic member 44 substantially coincide with each other in plan view. In other words, the leak-proof cuff part 42 and the leg elastic part 43 are fixed via an adhesive applied to the branch line elastic member 44, for example, a hot melt adhesive. Instead, the cover sheet 33 located at the boundary between the leg elastic part 43 and the leak-proof cuff part 42 and the back sheet 31 included in the leak-proof cuff part 42 are joined with an adhesive, for example, a hot melt adhesive. By using the branch line 41, the leak-proof cuff part 42 and the leg elastic part 43 can be fixed at the branch line 41. In this case, the branch line elastic member 44 is disposed between the branch line 41 and the leak-proof cuff elastic member 45 at a position adjacent to the branch line 41 and fixed to the leak-proof cuff part 42.
　防漏カフ部４２は、分岐線４１から横方向Ｘに離間して縦方向Ｙに延びる自由縁４２ｃを有し、自由縁４２ｃに沿って防漏カフ弾性部材４５が伸長状態で固定される。防漏カフ部４２の縦方向Ｙ両端部に位置する防漏カフ前後端部４２ａ，４２ｂは、サイドフラップ４０の肌対向面に接着剤、例えばホットメルト接着剤５０により接合される。ここで、防漏カフ前後端部４２ａ，４２ｂに含まれる防漏カフ弾性部材４５を、吸収体３２の両側縁３２ｃの横方向Ｘ外側に配置することが好ましい。また、防漏カフ弾性部材４５は、吸収体３２の側縁３２ｃに近接させることが好ましく、例えば吸収体３２の側縁３２ｃと、防漏カフ弾性部材４５との横方向Ｘにおける離間距離を２ｃｍ以内にすることが好ましい。防漏カフ前後端部４２ａ，４２ｂの間に延在する自由縁４２ｃは、おむつ１０の着用時に防漏カフ弾性部材４５が収縮することにより吸収体３２に対して立ち上がる。これにより、防漏カフ部４２が***物の漏れを防止する堰として機能する。 The leak-proof cuff part 42 has a free edge 42c that is spaced apart from the branch line 41 in the horizontal direction X and extends in the vertical direction Y, and the leak-proof cuff elastic member 45 is fixed in an extended state along the free edge 42c. The leakproof cuff front and rear end portions 42 a and 42 b positioned at both ends in the longitudinal direction Y of the leakproof cuff portion 42 are joined to the skin facing surface of the side flap 40 by an adhesive, for example, a hot melt adhesive 50. Here, it is preferable that the leak-proof cuff elastic member 45 included in the front and rear end portions 42 a and 42 b of the leak-proof cuff is disposed outside the lateral direction X of the side edges 32 c of the absorber 32. Further, the leak-proof cuff elastic member 45 is preferably close to the side edge 32c of the absorber 32. For example, the separation distance in the lateral direction X between the side edge 32c of the absorber 32 and the leak-proof cuff elastic member 45 is 2 cm. Is preferably within. The free edge 42c extending between the leakproof cuff front and rear end portions 42a and 42b rises with respect to the absorber 32 when the leakproof cuff elastic member 45 contracts when the diaper 10 is worn. Thereby, the leak-proof cuff part 42 functions as a weir which prevents the leakage of excrement.
　本実施形態では、防漏カフ弾性部材４５は被覆シート３３を折り返した内側に接合されている。防漏カフ弾性部材４５には、繊度が約３００～９４０ｄｔｅｘの１条以上のストランド状の弾性材料を、伸長倍率が約１．５～３．０倍になるようにして用いることができる。本実施形態では、４７０ｄｔｅｘの弾性糸２本を伸長倍率２．８倍で伸長させて用いている。しかし本発明はこれに限定されず、例えば３１０ｄｔｅｘの弾性糸２本を伸長倍率２．２倍で伸長させて用いる等、種々変更して実施することができる。また本実施形態では、防漏カフ部４２の防漏カフ前後端部４２ａ，４２ｂは、防漏カフ部４２を縦方向中心線Ｐに向けて横倒しにした状態で前後ウエストパネル１６，１７に接合している。しかし本発明はこれに限定されず、例えば図６に示すように、防漏カフ弾性部材４５が配置された自由縁４２ｃを縦方向中心線Ｐから遠ざかる方向に折り曲げ、防漏カフ前後端部４２ａ，４２ｂにおいて自由縁４２ｃを折り畳んだ状態にして前後ウエストパネル１６，１７に接合することもできる。このように防漏カフ部４２の自由縁４２ｃを折り畳むことにより、自由縁４２ｃの剛性が向上して、レッグ弾性部４３と防漏カフ部４２とが重なり合ったり交差したりすることがより有効に防止される。 In this embodiment, the leak-proof cuff elastic member 45 is joined to the inner side where the covering sheet 33 is folded. For the leak-proof cuff elastic member 45, one or more strand-shaped elastic materials having a fineness of about 300 to 940 dtex can be used so that the expansion ratio is about 1.5 to 3.0 times. In the present embodiment, two elastic yarns of 470 dtex are stretched at a stretching magnification of 2.8 times. However, the present invention is not limited to this, and can be implemented with various modifications such as, for example, using two elastic yarns of 310 dtex while being stretched at a stretch ratio of 2.2. In the present embodiment, the leakproof cuff front and rear end portions 42a and 42b of the leakproof cuff portion 42 are joined to the front and rear waist panels 16 and 17 in a state where the leakproof cuff portion 42 is laid sideways toward the longitudinal center line P. is doing. However, the present invention is not limited to this. For example, as shown in FIG. 6, the free edge 42c on which the leak-proof cuff elastic member 45 is disposed is bent away from the longitudinal center line P, and the leak-proof cuff front and rear end portions 42a. 42b can be joined to the front and rear waist panels 16, 17 with the free edge 42c folded. By folding the free edge 42c of the leak-proof cuff portion 42 in this way, the rigidity of the free edge 42c is improved, and it is more effective that the leg elastic portion 43 and the leak-proof cuff portion 42 overlap or cross each other. Is prevented.
　防漏カフ部４２の分岐線４１から自由縁４２ｃに至る部分では、非透液性の被覆シート３３と、非透液性のバックシート３１とが重なり合う。これにより、吸収体３２に対して立ち上がった一対の防漏カフ部４２の間に溜まった***物が防漏カフ部４２から滲みだすことが防止される。また、一対の防漏カフ部４２の分岐線４１の間に透液性を有する身体側ライナー３０を吸収体３２の肌対向面上に配置し、一対の防漏カフ部４２の間に***された尿が速やかに吸収体３２へ導かれるようにすることにより、尿が防漏カフ部４２からあふれ出すことを防止している。防漏カフ部４２がレッグ弾性部４３に重なることを防止するために、防漏カフ部４２の分岐線４１から自由縁４２ｃに至る距離が、分岐線４１からレッグ弾性部４３の遠位縁４０ｃに至る距離とほぼ同じか短いことが好ましい。 In the part from the branch line 41 to the free edge 42c of the leak-proof cuff part 42, the non-liquid-permeable covering sheet 33 and the non-liquid-permeable back sheet 31 overlap. This prevents excrement accumulated between the pair of leak-proof cuff portions 42 rising with respect to the absorber 32 from leaking out of the leak-proof cuff portion 42. Further, a body-side liner 30 having liquid permeability is disposed on the skin-facing surface of the absorbent body 32 between the branch lines 41 of the pair of leak-proof cuff parts 42 and is excreted between the pair of leak-proof cuff parts 42. The urine is prevented from overflowing from the leak-proof cuff portion 42 by promptly guiding the urine to the absorber 32. In order to prevent the leak-proof cuff portion 42 from overlapping the leg elastic portion 43, the distance from the branch line 41 to the free edge 42 c of the leak-proof cuff portion 42 is the distance from the branch line 41 to the distal edge 40 c of the leg elastic portion 43. It is preferable that the distance to be approximately the same or shorter.
　図２を参照して、おむつ１０の前後ウエストパネル１６，１７に接合されたサイドフラップ前後端部４０ａ，４０ｂの平面視において、おむつ１０の縦方向中心線Ｐから遠ざかる方向に沿って順に、防漏カフ弾性部材４５、分岐線弾性部材４４、脚回り弾性部材４６が位置する。おむつ１０が着用されたとき、おむつ１０の前後ウエストパネル１６，１７に接合されたサイドフラップ前後端部４０ａ，４０ｂは、着用者の胴回り方向、すなわちおむつ１０の横方向Ｘに伸長されるが、おむつ１０の前後ウエストパネル１６，１７に対し接合された防漏カフ弾性部材４５と脚回り弾性部材４６とが、互いに横方向Ｘにおいて離間する位置関係が維持される。 With reference to FIG. 2, in the plan view of the side flap front and rear end portions 40 a and 40 b joined to the front and rear waist panels 16 and 17 of the diaper 10, the protection is sequentially performed along the direction away from the longitudinal center line P of the diaper 10. The leakage cuff elastic member 45, the branch line elastic member 44, and the leg-hole elastic member 46 are located. When the diaper 10 is worn, the side flap front and rear end portions 40a and 40b joined to the front and rear waist panels 16 and 17 of the diaper 10 are extended in the wearer's waist direction, that is, in the lateral direction X of the diaper 10. The positional relationship in which the leakage-proof cuff elastic member 45 and the leg-hole elastic member 46 joined to the front and rear waist panels 16 and 17 of the diaper 10 are separated from each other in the lateral direction X is maintained.
　おむつ１０が着用されたとき、図５に模式的に示すように、おむつ１０の股間域１３において、防漏カフ弾性部材４５と脚回り弾性部材４６との間に位置する分岐線弾性部材４４が、防漏カフ部４２とレッグ弾性部４３との間に位置する分岐線４１をウエスト開口１８に向けて引き上げる。この結果、分岐線４１がずり下がることが防止されて防漏カフ部４２とレッグ弾性部４３とが成す角が維持され、防漏カフ部４２とレッグ弾性部４３とが重なり合ったり交差したりすることが防止される。また、吸収体３２の両側縁３２ｃに沿って配置された側方弾性部材４７は、吸収体３２をウエスト開口１８に向けて引き上げる。平面視において防漏カフ弾性部材４５は吸収体３２の側縁３２ｃの横方向Ｘ外側に位置し、レッグ弾性部４３は防漏カフ弾性部材４５よりもさらに横方向Ｘ外側に位置する。このため、図５に示すように、股間域１３においてレッグ弾性部４３がおむつ１０の横方向Ｘ外側に突き出すとともに、サイドフラップ４０において吸収体３２の側縁３２ｃからレッグ弾性部４３に至る部分が斜め上方に延び出す。この結果、吸収体３２の両側に、おむつ１０の内側から見たとき横方向Ｘ外側に窪んだポケット構造４８が安定的に形成される。ここで、防漏カフ弾性部材４５の収縮力の方が、レッグ弾性部４３に含まれる脚回り弾性部材４６の収縮力より大きいことが好ましい。これにより、吸収体３２の両横におむつ１０の内側から見たとき横方向Ｘ外側に窪んだポケット構造４８が安定的に形成されやすくなる。このポケット構造４８に進入した***物は、防漏カフ部４２と、サイドフラップ４０において吸収体３２の両側縁３２ｃからレッグ弾性部４３に至る部分との間に保持されるので、おむつ１０の漏れ防止性能が向上する。 When the diaper 10 is worn, as schematically shown in FIG. 5, the branch line elastic member 44 located between the leak-proof cuff elastic member 45 and the leg-hole elastic member 46 is located in the crotch region 13 of the diaper 10. The branch line 41 located between the leak-proof cuff part 42 and the leg elastic part 43 is pulled up toward the waist opening 18. As a result, the branch line 41 is prevented from sliding down, the angle formed by the leak-proof cuff portion 42 and the leg elastic portion 43 is maintained, and the leak-proof cuff portion 42 and the leg elastic portion 43 overlap or cross each other. It is prevented. Further, the side elastic members 47 arranged along the side edges 32 c of the absorber 32 pull up the absorber 32 toward the waist opening 18. In plan view, the leak-proof cuff elastic member 45 is located outside the lateral edge X of the side edge 32 c of the absorber 32, and the leg elastic part 43 is located further outside the leak-proof cuff elastic member 45 in the lateral direction X. For this reason, as shown in FIG. 5, the leg elastic portion 43 protrudes outward in the lateral direction X of the diaper 10 in the crotch region 13, and a portion from the side edge 32 c of the absorber 32 to the leg elastic portion 43 in the side flap 40. Extends diagonally upward. As a result, pocket structures 48 that are recessed outward in the lateral direction X when viewed from the inside of the diaper 10 are stably formed on both sides of the absorber 32. Here, it is preferable that the contraction force of the leak-proof cuff elastic member 45 is larger than the contraction force of the leg-hole elastic member 46 included in the leg elastic part 43. Thereby, when it sees from the inner side of the diaper 10 on both sides of the absorber 32, it becomes easy to form stably the pocket structure 48 recessed in the horizontal direction X outer side. Since the excrement that has entered the pocket structure 48 is held between the leak-proof cuff portion 42 and the side flap 40 between the side edges 32c of the absorber 32 to the leg elastic portion 43, the diaper 10 leaks. Prevention performance is improved.
　防漏カフ前後端部４２ａ，４２ｂを吸収体３２の両側縁３２ｃの内側に配置した場合、サイドフラップ４０において吸収体３２の側縁３２ｃからレッグ弾性部４３に至る部分が垂直に立ち上がる形状になって、おむつ１０の内側から見たときに横方向Ｘ外側に窪んだポケット構造４８が形成されにくくなる。このため、防漏カフ弾性部材４５は、吸収体３２の側縁３２ｃの横方向Ｘ外側に配置することが好ましい。 When the front and rear end portions 42a and 42b of the leak-proof cuff are arranged inside the both side edges 32c of the absorber 32, the side flap 40 has a shape that rises vertically from the side edge 32c of the absorber 32 to the leg elastic portion 43. Thus, when viewed from the inside of the diaper 10, the pocket structure 48 that is recessed outward in the lateral direction X is difficult to be formed. For this reason, it is preferable that the leak-proof cuff elastic member 45 is disposed outside the lateral edge X of the side edge 32 c of the absorber 32.
　また、サイドフラップ前後端部４０ａ，４０ｂが接合された前後胴回り域１１，１２の平面視において、横方向Ｘに延びる前後胴回り弾性部材２５，２６と、縦方向Ｙに延びる防漏カフ弾性部材４５、分岐線弾性部材４４、及び脚回り弾性部材４６とが交差するように配置すれば、各弾性部材が連動し、また防漏カフ弾性部材４５、分岐線弾性部材４４、及び脚回り弾性部材４６を横方向Ｘに確実に離間させることができるので好ましい。但し、各弾性部材が連動可能である限り、交差していることは必須ではなく、例えば２０ｍｍ以内の範囲で離間していてもよい。また、前後胴回り域１１，１２にサイドフラップ前後端部４０ａ，４０ｂを接合する際、前後胴回り弾性部材２５，２６と、防漏カフ弾性部材４５、分岐線弾性部材４４、及び脚回り弾性部材４６とが交差する位置に接着剤、例えばホットメルト接着剤を塗布することが好ましい。これにより、各弾性部材の連動性を高めることができる。 Further, the front and rear waistline elastic members 25 and 26 extending in the transverse direction X and the leakage-proof cuff elastic member 45 extending in the longitudinal direction Y in plan view of the front and rear waistline regions 11 and 12 to which the side flap front and rear end portions 40a and 40b are joined. If the branch line elastic member 44 and the leg-line elastic member 46 are arranged so as to intersect with each other, the respective elastic members are interlocked, and the leak-proof cuff elastic member 45, the branch line elastic member 44, and the leg-line elastic member 46 are linked. Can be reliably separated in the lateral direction X, which is preferable. However, as long as each elastic member can be interlocked, it is not essential to cross each other, and may be separated within a range of, for example, 20 mm. Further, when the side flap front and rear end portions 40a, 40b are joined to the front / rear waist regions 11, 12, the front / rear waist elastic members 25, 26, the leak-proof cuff elastic member 45, the branch line elastic member 44, and the leg-hole elastic member 46 are used. It is preferable to apply an adhesive, for example, a hot melt adhesive, at a position where the crosses. Thereby, the interlocking | linkage of each elastic member can be improved.
　以上の説明では、脚回り弾性部材４６が複数条のストランド状の弾性材料である場合について記述した。しかし図７に例示するように、ストランド状の弾性材料に代えて帯状の伸縮不織布を脚回り弾性部材４６として用い、レッグ弾性部４３の３つのサブ領域４９のそれぞれに１片の帯状の伸縮不織布を接合することもできる。この場合も、レッグ弾性部４３において分岐線４１に隣接するサブ領域４９に含まれる帯状の伸縮不織布の収縮力を、遠位縁４０ｃに隣接するサブ領域４９に含まれる帯状の伸縮不織布の収縮力よりも大きくすることが好ましい。また、帯状の伸縮不織布を横方向Ｘに互いに離間させることが好ましい。脚回り弾性部材４６として帯状の伸縮不織布を用いることによっても、着用時にレッグ弾性部４３と防漏カフ部４２とが重なり合ったり交差したりすることが防止され、また安定的にポケット構造が形成される。 In the above description, the case where the leg-hole elastic member 46 is a plurality of strand-like elastic materials has been described. However, as illustrated in FIG. 7, a band-shaped stretchable nonwoven fabric is used as the leg-hole elastic member 46 instead of the strand-shaped elastic material, and one strip-shaped stretchable nonwoven fabric is provided in each of the three sub-regions 49 of the leg elastic portion 43. Can also be joined. Also in this case, in the leg elastic part 43, the contraction force of the strip-shaped stretchable nonwoven fabric included in the sub-region 49 adjacent to the branch line 41 is the contraction force of the strip-shaped stretchable nonwoven fabric included in the sub-region 49 adjacent to the distal edge 40c. It is preferable to make it larger. Moreover, it is preferable that the belt-shaped stretchable nonwoven fabrics are separated from each other in the lateral direction X. Also by using a belt-like stretchable nonwoven fabric as the leg elastic member 46, the leg elastic portion 43 and the leak-proof cuff portion 42 are prevented from overlapping or intersecting when worn, and a pocket structure is stably formed. The
