上記特許文献１記載の吸収性物品においては、ウイング部の基端部寄りの部位における非伸張性のシートに対してこれに積層される伸張性の不織布を貫通しない複数のスリットが形成されているため、ウイング部の基端部寄りの部位が、スリットの存在により良好に伸張し、ウイング部の股下部側縁に対するフィット性に優れるというものであるが、ウイング部（ウイング状フラップ）の裏面側に配設される非伸張性のシート（裏面シート）は一般に表面側の不織布より曲げ剛性が高いため、ウイング状フラップの基端部を折り返した状態では、折り返しによって鋭角状に変形した裏面シートの端縁が肌に当たるため、脚の付け根の違和感に繋がることがあった。 In the absorbent article described in Patent Document 1, a plurality of slits that do not pass through the stretchable nonwoven fabric laminated to the nonstretchable sheet in the portion near the base end of the wing portion are formed. Therefore, the part near the base end part of the wing part is stretched satisfactorily due to the presence of the slit, and the wing part has excellent fit to the crotch side edge, but the back side of the wing part (wing-shaped flap) In general, the non-stretchable sheet (back sheet) has a higher bending rigidity than the nonwoven fabric on the front side. Therefore, when the base end of the wing-shaped flap is folded back, Since the edge hits the skin, it may lead to a sense of incongruity at the base of the leg.

また、上記特許文献２記載の吸収性物品においては、本体部分の両側部にウイング状フラップが形成される場合、第１のフラップ部（立体ギャザー）の自由端部より外側にウイング状フラップの折り返し位置が形成されるため、装着中にウイング状フラップの折り返し部やショーツの側縁がずれることによって立体ギャザーがずれて、経血がウイング状フラップに付着し、その結果経血が脚の付け根やショーツに付着して汚すおそれがあった。 Further, in the absorbent article described in Patent Document 2, when wing-shaped flaps are formed on both side portions of the main body portion, the wing-shaped flaps are folded outward from the free end portion of the first flap portion (three-dimensional gather). Because the position is formed, the folded part of the wing-shaped flap and the side edge of the shorts are displaced during wearing, so that the three-dimensional gather is displaced, and menstrual blood adheres to the wing-shaped flap. There was a risk of fouling on the shorts.

そこで本発明の主たる課題は、肌当たりが良く、経血によって汚れるのを防止した吸収性物品及びその製造方法を提供することにある。 Then, the main subject of this invention is providing the absorbent article which the skin contact was good, and prevented being soiled by menstrual blood, and its manufacturing method.

上記課題を解決するために請求項１に係る本発明として、透液性表面シートと不透液性裏面シートとの間に吸収体が介在された本体部分の両側部にそれぞれ、装着時に基端部の折返し線に沿って折り返すことにより下着のクロッチ部分を巻き込むようにして固定されるウイング状フラップが形成されるとともに、表面側両側部にそれぞれ、肌側に起立する立体ギャザーを備えた吸収性物品において、
前記ウイング状フラップの折返し線は、前記立体ギャザーの幅方向外側縁より吸収性物品の幅方向中心側に位置するように形成されるとともに、
前記ウイング状フラップは裏面側の前記不透液性裏面シートと表面側の表面層との積層構造からなり、少なくとも前記折返し線の両端縁及びその近傍において、前記表面層を前記不透液性裏面シートより外側に延在させた表面層延在部が設けられていることを特徴とする吸収性物品が提供される。 In order to solve the above-mentioned problem, as the present invention according to claim 1, the base end at the time of mounting on the both sides of the main body portion in which the absorbent body is interposed between the liquid-permeable top sheet and the liquid-impervious back sheet, Wrap-like flaps are formed that are fixed so that the crotch part of the underwear is wound by folding back along the folding line of the part, and the absorbent with three-dimensional gathers that stand on the skin side on both sides of the surface side In goods,
The wrapping line of the wing-shaped flap is formed so as to be positioned on the center side in the width direction of the absorbent article from the outer edge in the width direction of the three-dimensional gather,
The wing-shaped flap has a laminated structure of the liquid-impervious back sheet on the back side and the surface layer on the front side, and the surface layer is formed on the liquid-impervious back surface at least at both ends of the folded line and in the vicinity thereof. There is provided an absorbent article characterized in that a surface layer extending portion extending outward from the sheet is provided.

上記請求項１記載の発明では、ウイング状フラップの折返し線が、立体ギャザーの幅方向外側縁より吸収性物品の幅方向中心側に位置するように形成されているため、装着状態では立体ギャザーの外側縁部がショーツの両側からはみ出た状態となるため、ショーツの圧力によって立体ギャザーが押さえ付けられるので、立体ギャザーのずれが抑制され、経血が立体ギャザーの外側に漏れるのが抑えられる結果、ウイング状フラップに経血が付着するのが防止でき、脚の付け根やショーツを汚すことがなくなる。 In the first aspect of the present invention, the wrapping line of the wing-shaped flap is formed so as to be located on the center side in the width direction of the absorbent article from the outer edge in the width direction of the three-dimensional gather. Since the outer edge is in a state protruding from both sides of the shorts, the three-dimensional gather is pressed by the pressure of the shorts, so that the shift of the three-dimensional gather is suppressed, and menstrual blood is prevented from leaking outside the three-dimensional gather. Menstrual blood can be prevented from adhering to the wing-shaped flap, and the base of the legs and shorts are not soiled.

また、ウイング状フラップとして裏面側の不透液性裏面シートと表面側の表面層との積層構造によって構成し、少なくともウイング状フラップの折返し線の両端縁及びその近傍において、表面層を不透液性裏面シートより外側に延在させた表面層延在部を設けているため、ウイング状フラップを折返し線から折り返して下着のクロッチ部分を巻き込むようにして固定した状態でも、プラスチックなどからなる不透液性裏面シートに比べて不織布などからなる表面層の方が曲げ剛性が低いため、鋭角状に変形した不透液性裏面シートが表面層によって覆われ、不透液性裏面シートが直接肌に当たることがなくなる結果、脚の付け根の違和感が大幅に軽減できる。さらに、上記の通りウイング状フラップの折返し線より立体ギャザーの幅方向外側縁が吸収性物品の幅方向外側に位置しているので、前述の鋭角状に変形した不透液性裏面シートは、表面層に加えて更にその内側が立体ギャザーによって覆われるため、より肌当たりの良いものとなる。 The wing-shaped flap is constituted by a laminated structure of a liquid-impervious back sheet on the back side and a surface layer on the front side, and the surface layer is impervious at least at both ends of the wrapping line of the wing-shaped flap and in the vicinity thereof. Even if the wing-shaped flap is folded back from the fold line and the crotch portion of the underwear is fixed, the impervious material made of plastic or the like is provided. Since the surface layer made of nonwoven fabric has lower bending rigidity than the liquid back sheet, the liquid-impervious back sheet deformed into an acute angle is covered with the surface layer, and the liquid-impervious back sheet directly hits the skin. As a result, the discomfort at the base of the legs can be greatly reduced. Further, as described above, the outer edge in the width direction of the three-dimensional gather is located on the outer side in the width direction of the absorbent article from the folding line of the wing-shaped flap. In addition to the layers, the inside is further covered with a three-dimensional gather, so that the skin is more comfortable.

〔生理用ナプキン１の基本的構造〕
本発明に係る生理用ナプキン１は、ポリエチレンシート、ポリプロピレンシートなどからなる不透液性裏面シート２と、経血やおりものなどを速やかに透過させる透液性表面シート３と、これら両シート２，３間に介在された綿状パルプまたは合成パルプなどからなる吸収体４と、この吸収体４の形状保持および拡散性向上のために前記吸収体４を囲繞するクレープ紙５と、前記透液性表面シート３とクレープ紙５との間に介在された親水性不織布からなるセカンドシート６と、表面両側部にそれぞれ長手方向に沿って形成されたサイド不織布７，７とから構成されている。前記吸収体４の周囲において、その上下端縁部では、前記不透液性裏面シート２と透液性表面シート３との外縁部がホットメルトなどの接着剤や熱圧着等の接合手段によって接合され、またその両側縁部では吸収体４よりも側方に延出している前記不透液性裏面シート２と前記サイド不織布７とがホットメルトなどの接着剤や熱圧着等の接合手段によって接合されている。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[Basic structure of sanitary napkin 1]
The sanitary napkin 1 according to the present invention includes a liquid-impervious back sheet 2 made of a polyethylene sheet, a polypropylene sheet, etc., a liquid-permeable top sheet 3 that allows permeation of menstrual blood or vaginal discharge, and the both sheets 2. , 3, an absorbent body 4 made of cotton-like pulp or synthetic pulp, crepe paper 5 surrounding the absorbent body 4 for maintaining the shape and improving the diffusibility of the absorbent body 4, and the liquid permeable liquid The second sheet 6 is made of a hydrophilic nonwoven fabric interposed between the conductive surface sheet 3 and the crepe paper 5, and the side nonwoven fabrics 7 and 7 are formed on both sides of the surface along the longitudinal direction. Around the absorber 4, at the upper and lower edge portions, the outer edge portions of the liquid-impermeable back sheet 2 and the liquid-permeable surface sheet 3 are bonded by an adhesive such as hot melt or a bonding means such as thermocompression bonding. In addition, the liquid-impervious back sheet 2 and the side nonwoven fabric 7 which extend laterally from the absorbent body 4 at both side edges thereof are bonded by an adhesive such as hot melt or a bonding means such as thermocompression bonding. Has been.

以下、さらに前記生理用ナプキン１の構造について詳述すると、
前記不透液性裏面シート２は、ポリエチレンやポリプロピレン等のオレフィン系樹脂シートなどの少なくとも遮水性を有するシート材が用いられるが、この他にポリエチレンシート等に不織布を積層したラミネート不織布や、さらには防水フィルムを介在して実質的に不透液性を確保した上で不織布シート（この場合には防水フィルムと不織布とで不透液性裏面シートを構成する。）などを用いることができる。近年はムレ防止の観点から透湿性を有するものが用いられる傾向にある。この遮水・透湿性シート材は、ポリエチレンやポリプロピレン等のオレフィン系樹脂中に無機充填剤を溶融混練してシートを成形した後、一軸または二軸方向に延伸することにより得られる微多孔性シートである。 Hereinafter, the structure of the sanitary napkin 1 will be described in detail.
As the liquid-impermeable back sheet 2, a sheet material having at least water shielding properties such as an olefin resin sheet such as polyethylene or polypropylene is used. In addition, a laminated nonwoven fabric obtained by laminating a nonwoven fabric on a polyethylene sheet or the like, or A nonwoven fabric sheet (in this case, the waterproof film and the nonwoven fabric constitute a liquid-impervious back sheet) can be used after substantially impervious to liquid imperviousness by interposing a waterproof film. In recent years, those having moisture permeability tend to be used from the viewpoint of preventing stuffiness. This water- and moisture-permeable sheet material is a microporous sheet obtained by forming a sheet by melting and kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene, and then stretching in a uniaxial or biaxial direction. It is.

前記透液性表面シート３は、有孔または無孔の不織布や多孔性プラスチックシートなどが好適に用いられる。不織布を構成する素材繊維としては、たとえばポリエチレンまたはポリプロピレン等のオレフィン系、ポリエステル系、ポリアミド系等の合成繊維の他、レーヨンやキュプラ等の再生繊維、綿等の天然繊維とすることができ、スパンレース法、スパンボンド法、サーマルボンド法、メルトブローン法、ニードルパンチ法等の適宜の加工法によって得られた不織布を用いることができる。これらの加工法の内、スパンレース法は柔軟性、ドレープ性に富む点で優れ、サーマルボンド法は嵩高でソフトである点で優れている。なお、前記透液性表面シート３の上面側から各種のエンボスを付与し、体液の滞留を促進し吸収効率を高めることにより横漏れを防止するのが望ましい。 As the liquid-permeable surface sheet 3, a porous or non-porous nonwoven fabric or a porous plastic sheet is preferably used. Examples of the material fibers constituting the nonwoven fabric include synthetic fibers such as polyethylene or polypropylene, synthetic fibers such as polyester and polyamide, recycled fibers such as rayon and cupra, and natural fibers such as cotton. A nonwoven fabric obtained by an appropriate processing method such as a lace method, a spun bond method, a thermal bond method, a melt blown method, or a needle punch method can be used. Among these processing methods, the spunlace method is excellent in terms of flexibility and drapeability, and the thermal bond method is excellent in terms of being bulky and soft. In addition, it is desirable to prevent side leakage by applying various embosses from the upper surface side of the liquid-permeable surface sheet 3 to promote retention of bodily fluids and increase absorption efficiency.

前記不透液性裏面シート２と透液性表面シート３との間に介在される吸収体４は、たとえばフラッフ状パルプと吸水性ポリマーとにより構成されている。前記吸水性ポリマーは吸収体を構成するパルプ中に、例えば粒状粉として混入されている。前記パルプとしては、木材から得られる化学パルプ、溶解パルプ等のセルロース繊維や、レーヨン、アセテート等の人工セルロース繊維からなるものが挙げられ、広葉樹パルプよりは繊維長の長い針葉樹パルプの方が機能および価格の面で好適に使用される。本例のように、吸収体４を囲繞するクレープ紙５を設ける場合には、結果的に透液性表面シート３と吸収体４との間にクレープ紙５が介在することになり、吸収性に優れる前記クレープ紙５によって体液を速やかに拡散させるとともに、これら経血等の逆戻りを防止するようになる。 The absorbent body 4 interposed between the liquid-impervious back sheet 2 and the liquid-permeable top sheet 3 is made of, for example, fluffy pulp and a water-absorbing polymer. The water-absorbing polymer is mixed in the pulp constituting the absorber, for example, as granular powder. Examples of the pulp include chemical fibers obtained from wood, cellulose fibers such as dissolved pulp, and artificial cellulose fibers such as rayon and acetate. Softwood pulp having a longer fiber length than hardwood pulp functions and It is preferably used in terms of price. When the crepe paper 5 surrounding the absorbent body 4 is provided as in this example, the crepe paper 5 is interposed between the liquid-permeable surface sheet 3 and the absorbent body 4 as a result. The crepe paper 5 which is excellent in diffusing body fluids quickly prevents reversal of menstrual blood and the like.

また、前記吸収体４には合成繊維を混合しても良い。前記合成繊維は、例えばポリエチレン又はポリプロピレン等のポリオレフィン系、ポリエチレンテレフタレートやポリブチレンテレフタレート等のポリエステル系、ナイロンなどのポリアミド系、及びこれらの共重合体などを使用することができるし、これら２種を混合したものであってもよい。また、融点の高い繊維を芯とし融点の低い繊維を鞘とした芯鞘型繊維やサイドバイサイド型繊維、分割型繊維などの複合繊維も用いることができる。前記合成繊維は、体液に対する親和性を有するように、疎水性繊維の場合には親水化剤によって表面処理したものを用いるのが望ましい。 The absorbent body 4 may be mixed with synthetic fibers. As the synthetic fiber, for example, polyolefins such as polyethylene or polypropylene, polyesters such as polyethylene terephthalate and polybutylene terephthalate, polyamides such as nylon, and copolymers thereof can be used. It may be a mixture. In addition, a composite fiber such as a core-sheath fiber, a side-by-side fiber, or a split fiber having a fiber having a high melting point as a core and a fiber having a low melting point as a sheath can also be used. In the case of a hydrophobic fiber, it is desirable to use a synthetic fiber that has been surface-treated with a hydrophilizing agent so as to have an affinity for body fluids.

前記透液性表面シート３とクレープ紙５との間に介在された親水性不織布からなるセカンドシート６は、たとえばポリエチレンまたはポリプロピレン等のオレフィン系、ポリエステル系、ポリアミド系等の合成繊維の他、レーヨンやキュプラ等の再生繊維、綿等の天然繊維とすることができ、スパンレース法、スパンボンド法、サーマルボンド法、メルトブローン法、ニードルパンチ法等の適宜の加工法によって得られた不織布を用いることができる。親水性を付与するには、合成繊維の製造過程で親水基を持つ化合物、例えばポリエチレングリコールの酸化生成物などを共存させて重合させる方法や、塩化第２スズのような金属塩で処理し、表面を部分溶解し多孔性とし金属の水酸化物を沈着させる方法等により合成繊維を膨潤または多孔性とし、毛細管現象を応用して親水性を与えることができる。 The second sheet 6 made of a hydrophilic non-woven fabric interposed between the liquid-permeable surface sheet 3 and the crepe paper 5 is made of, for example, synthetic fibers such as olefin-based, polyester-based, and polyamide-based fibers such as polyethylene or polypropylene, and rayon. Can be made of natural fibers such as spunlace, spunbond, thermal bond, melt blown, needle punch, etc. Can do. In order to impart hydrophilicity, a method of polymerizing a compound having a hydrophilic group, for example, an oxidation product of polyethylene glycol, in the process of producing a synthetic fiber, or treatment with a metal salt such as stannic chloride, Synthetic fibers can be made to swell or become porous by a method such as partially dissolving the surface to make it porous and depositing metal hydroxide, etc., and applying capillary action to impart hydrophilicity.

前記透液性表面シート３と不透液性裏面シート２との間に吸収体４が介在された本体部分の非肌当接面には、下着に対する固定のために適宜の塗布パターンによって複数条の本体ズレ止め粘着剤層（図示せず）が形成されるとともに、これら本体ズレ止め粘着剤層が図示されない本体用剥離材によって覆われている。また、前記ウイング状フラップＷ、Ｗの不透液性裏面シート２側の外面には、ウイングズレ止め粘着剤層（図示せず）が形成されるとともに、これらウイングズレ止め粘着剤層が図示されないウイング用剥離材によって覆われている。 On the non-skin contact surface of the main body portion where the absorbent body 4 is interposed between the liquid-permeable top sheet 3 and the liquid-impervious back sheet 2, a plurality of strips are formed by an appropriate application pattern for fixing to the underwear. The main body misalignment prevention adhesive layer (not shown) is formed, and these main body misalignment prevention adhesive layers are covered with a main body release material (not shown). In addition, a wings prevention adhesive layer (not shown) is formed on the outer surface of the wing-shaped flaps W, W on the liquid-impermeable back sheet 2 side, and these wings prevention adhesive layers are not shown. Covered with a wing release material.

〔立体ギャザーＢＳの構造〕
一方、本生理用ナプキン１の表面がわ両側部にはそれぞれ、長手方向に沿ってかつナプキン１のほぼ全長に亘ってサイド不織布７，７が設けられ、このサイド不織布７，７の一部が側方に延在されるとともに、同じく側方に延在された不透液性裏面シート２の一部とによりウイング状フラップＷ、Ｗが形成されている。 [Structure of solid gather BS]
On the other hand, side non-woven fabrics 7 and 7 are provided on both sides of the sanitary napkin 1 along the longitudinal direction and almost the entire length of the napkin 1, respectively. Wing-like flaps W, W are formed by a part of the liquid-impervious back sheet 2 that extends sideways and also extends sideways.

前記サイド不織布７としては、重要視する機能の点から撥水処理不織布または親水処理不織布を使用することができる。たとえば、経血やおりもの等が浸透するのを防止する、あるいは肌触り感を高めるなどの機能を重視するならば、シリコン系、パラフィン系、アルキルクロミッククロリド系撥水剤などをコーティングした撥水処理不織布を用いることが望ましい。また、前記ウイング状フラップＷ、Ｗにおける経血等の吸収性を重視するならば、合成繊維の製造過程で親水基を持つ化合物、例えばポリエチレングリコールの酸化生成物などを共存させて重合させる方法や、塩化第２スズのような金属塩で処理し、表面を部分溶解し多孔性とし金属の水酸化物を沈着させる方法等により合成繊維を膨潤または多孔性とし、毛細管現象を応用して親水性を与えた親水処理不織布を用いるようにする。 As the side nonwoven fabric 7, a water-repellent treated nonwoven fabric or a hydrophilic treated nonwoven fabric can be used from the viewpoint of an important function. For example, if importance is placed on functions such as preventing permeation of menstrual blood or vaginal discharge, or enhancing the touch feeling, water repellent treatment coated with silicon, paraffin or alkylchromic chloride water repellent It is desirable to use a nonwoven fabric. Further, if importance is attached to the absorption of menstrual blood and the like in the wing-shaped flaps W, W, a method of polymerizing a compound having a hydrophilic group, for example, an oxidation product of polyethylene glycol, in the process of producing a synthetic fiber, , By treating with a metal salt such as stannic chloride, partially dissolving the surface to make it porous, and depositing metal hydroxides to swell or make the synthetic fiber porous, applying capillary action to make it hydrophilic The hydrophilic treatment nonwoven fabric which gave is used.

前記サイド不織布７は、不透液性裏面シート２より相対的に曲げ剛性が低い、柔らかい素材を使用する。これにより、相対的に硬い不透液性裏面シート２の端縁が直接肌に当たることが防止できる。 The side nonwoven fabric 7 is made of a soft material having relatively lower bending rigidity than the liquid-impermeable back sheet 2. Thereby, it can prevent that the edge of the relatively hard liquid-impermeable back sheet 2 hits skin directly.

前記サイド不織布７は、図２に示されるように、生理用ナプキン１の幅方向外側から幅方向中心側に向けて配設され、ナプキン１の幅方向中心側で外側に折り返されるとともに、その折り返し端部で更に折り返されることにより少なくとも透液性表面シート３と接着する部分までが二重シートとされ、この二重シート内部の折り返し端部側の適宜の位置に両端または長手方向の適宜の位置が固定された１本又は複数本の、図示例では２本の弾性伸縮部材８、８がナプキン長手方向に沿って配設されている。このサイド不織布７の外側への折返し部分によって、肌側に起立する立体ギャザーＢＳ、ＢＳが形成されている。 As shown in FIG. 2, the side nonwoven fabric 7 is disposed from the outer side in the width direction of the sanitary napkin 1 toward the center side in the width direction, and is folded outward at the center side in the width direction of the napkin 1. By further folding back at the end portion, at least the portion that adheres to the liquid-permeable surface sheet 3 is a double sheet, and at both positions or appropriate positions in the longitudinal direction at appropriate positions on the folded end side inside the double sheet. One or a plurality of elastic elastic members 8 and 8 in the illustrated example are fixed along the longitudinal direction of the napkin. Solid gathers BS and BS standing on the skin side are formed by the folded portion of the side nonwoven fabric 7 to the outside.

前記立体ギャザーＢＳの自由端部は、図２及び図３に示されるように、ウイング状フラップＷの折返し線ＲＬより幅方向外側に位置するように、立体ギャザーＢＳ基端の固定部の位置及び立体ギャザーＢＳの幅が規定されている。立体ギャザーＢＳの幅としては、肌との十分な密着性を確保するため、立体ギャザーＢＳの起立方向に沿って１０〜１５mmの幅で形成することが好ましい。 As shown in FIGS. 2 and 3, the free end portion of the three-dimensional gather BS is positioned on the outer side in the width direction from the folding line RL of the wing-shaped flap W, and The width of the three-dimensional gather BS is defined. The width of the three-dimensional gather BS is preferably formed with a width of 10 to 15 mm along the standing direction of the three-dimensional gather BS in order to ensure sufficient adhesion with the skin.

また、図示例では、立体ギャザーＢＳは、図２に示されるナプキン１の横断面視で、ナプキン１の幅方向中心側の固定部（基端部）から、ナプキン１の幅方向外側の自由端部（先端部）に向けてほぼ直線状に起立する形状とされているが、起立形状がくの字形やΣ状など、１又は複数の屈折部を有するものでもよい。この場合、ウイング状フラップＷの折返し線ＲＬよりナプキン１の幅方向外側に位置させる立体ギャザーＢＳの幅方向外側縁は、立体ギャザーＢＳのうち最もナプキン１の幅方向外側となる部分であればよく、前述の屈折部であってもよい。 Further, in the illustrated example, the three-dimensional gather BS is a free end on the outer side in the width direction of the napkin 1 from the fixed portion (base end portion) on the center side in the width direction of the napkin 1 in a cross-sectional view of the napkin 1 shown in FIG. Although it is set as the shape which stands | stands up substantially linearly toward a part (front-end | tip part), the standing shape may have one or a plurality of refracting parts such as a dogleg shape or a Σ shape. In this case, the outer edge in the width direction of the three-dimensional gather BS positioned on the outer side in the width direction of the napkin 1 from the fold line RL of the wing-shaped flap W may be a portion that is the outermost portion in the width direction of the napkin 1 among the three-dimensional gather BS. The aforementioned refraction part may be used.

〔ウイング状フラップＷの構造〕
ウイング状フラップＷは、前述の通り、裏面側の不透液性裏面シート２と表面側のサイド不織布７との積層構造からなり、ウイング状フラップＷの折返し線ＲＬの両端縁（ナプキン１の前後方向端縁）及びその近傍において、サイド不織布７を不透液性裏面シート２より外側に延在させた表面層延在部１０が設けられている。この表面層延在部１０を設けることによって、図３に示されるように、ウイング状フラップＷを折返し線ＲＬから折り返して下着のクロッチ部分を巻き込むようにして固定した状態でも、プラスチックなどからなる不透液性裏面シート２に比べて不織布などからなるサイド不織布７の方が曲げ剛性が低いため、鋭角状に変形した不透液性裏面シート２の端部２ａがサイド不織布７によって覆われ、直接肌に当たることがなくなる結果、脚の付け根の違和感が大幅に軽減できるようになる。 [Structure of wing-shaped flap W]
As described above, the wing-shaped flap W has a laminated structure of the liquid-impervious back sheet 2 on the back surface side and the side nonwoven fabric 7 on the front surface side, and both end edges of the wrapping line RL of the wing-shaped flap W (front and back of the napkin 1). In the vicinity of the direction edge) and the vicinity thereof, a surface layer extending portion 10 is provided in which the side nonwoven fabric 7 extends outward from the liquid-impermeable back sheet 2. By providing the surface layer extending portion 10, as shown in FIG. 3, even if the wing-shaped flap W is folded back from the fold line RL and the crotch portion of the underwear is wound and fixed, it is not made of plastic or the like. Since the side nonwoven fabric 7 made of a nonwoven fabric or the like has a lower bending rigidity than the liquid permeable back sheet 2, the end 2 a of the liquid-impermeable back sheet 2 deformed into an acute angle is covered with the side nonwoven fabric 7 and directly As a result of not touching the skin, the discomfort at the base of the legs can be greatly reduced.

また、前述の通り、ウイング状フラップＷの折返し線ＲＬが立体ギャザーＢＳの幅方向外側縁より吸収性物品の幅方向中心側に位置するように形成されているため、図３及び図４に示されるように、装着状態で、立体ギャザーＢＳの外側縁部がショーツの両側からはみ出た状態となるため、ショーツの圧力によって立体ギャザーＢＳが押さえ付けられるので、立体ギャザーＢＳのずれが抑制され、経血が立体ギャザーＢＳの外側に漏れるのを抑えることができる結果、ウイング状フラップＷに経血が付着するのが防止でき、脚の付け根やショーツの汚れが防止できるようになる。 Further, as described above, the folding line RL of the wing-shaped flap W is formed so as to be positioned on the center side in the width direction of the absorbent article from the outer edge in the width direction of the three-dimensional gather BS. As shown, since the outer edge of the three-dimensional gather BS protrudes from both sides of the shorts in the mounted state, the three-dimensional gather BS is pressed by the pressure of the shorts, so that the three-dimensional gather BS is prevented from shifting. As a result of preventing the blood from leaking to the outside of the three-dimensional gather BS, menstrual blood can be prevented from adhering to the wing-shaped flap W, and the base of the legs and the shorts can be prevented from being stained.

前記ウイング状フラップＷの折返し線ＲＬとは、装着時にウイング状フラップＷを下着のクロッチ部分を巻き込むようにして折り返すため、ウイング状フラップＷの基端部寄りのナプキン前後方向に亘って形成される折り線のことであり、図示例では、ウイング状フラップＷの前後の付け根に形成される凹部の底部を結んだ線としてある。折返し線ＲＬは、このような図示例の位置よりウイング状フラップＷの外側に設けることもできる。また、折返し線ＲＬに沿ってエンボス線などの折返し容易化手段を施しておいても良い。 The fold-back line RL of the wing-shaped flap W is formed over the napkin front-rear direction near the base end portion of the wing-shaped flap W in order to fold the wing-shaped flap W around the crotch portion of the underwear at the time of wearing. It is a fold line, and in the illustrated example, it is a line connecting the bottoms of the recesses formed at the front and back of the wing-shaped flap W. The folding line RL can also be provided outside the wing-shaped flap W from the position of the illustrated example. Further, a folding facilitating means such as an embossed line may be provided along the folding line RL.

前記表面層延在部１０は、少なくとも折返し線ＲＬの両端縁及びその近傍に設けてあれば良いが（図６参照）、これよりナプキン前後方向に延在して設けることもできる。図１に示されるように、折返し線ＲＬの両端縁及びその近傍からそれぞれナプキン前後端部に亘るナプキン幅方向両側に設けた場合には、ナプキン本体部分の両側部においても不透液性裏面シート２の端部が脚の付け根に直接接触するのが防止できるし、図５(A)に示されるように、折返し線ＲＬの両端縁及びその近傍からそれぞれナプキン１の前後の各周縁部に設た場合には、生理用ナプキン１の前後端縁が腹部や臀部に直接接触することも防止できるし、図５(B)に示されるように、ウイング状フラップＷの両側縁部を含めた生理用ナプキン１の全周縁に設けた場合には、ウイング状フラップＷを折り返す作業中に指先に不透液性裏面シートの端縁が接触することも防止でき、硬さを感じさせない仕様になる。 The surface layer extending portion 10 may be provided at least at both ends of the folding line RL and in the vicinity thereof (see FIG. 6), but can also be provided extending in the front-rear direction of the napkin. As shown in FIG. 1, when provided on both sides of the napkin in the napkin width direction extending from both ends of the fold line RL and the vicinity thereof to the front and rear ends of the napkin, the liquid-impervious back sheet is also provided on both sides of the napkin main body. 2 can be prevented from coming into direct contact with the base of the leg, and as shown in FIG. 5 (A), it is provided at each of the peripheral edges of the napkin 1 before and after the both ends of the folding line RL and its vicinity. In this case, it is possible to prevent the front and rear edges of the sanitary napkin 1 from coming into direct contact with the abdomen and the buttocks, and the physiology including both side edges of the wing-shaped flap W as shown in FIG. When the napkin 1 is provided on the entire periphery, it is possible to prevent the edge of the liquid-impervious back sheet from coming into contact with the fingertip during the operation of folding the wing-shaped flap W, so that the hardness does not feel.

また、図６に示されるように、ウイング状フラップＷの付け根の不透液性裏面シート２の形状としては、同図(A)に示される曲線形や、(B)の角形などとすることができ、さらには(C)のようにウイング状フラップＷの付け根の不透液性裏面シート２を裂け難くするためコーナーの頂部がフラスコ形にえぐられた形状にすることもできる。 Further, as shown in FIG. 6, the shape of the liquid-impervious back sheet 2 at the base of the wing-shaped flap W is a curved shape shown in FIG. Further, as shown in (C), in order to make it difficult to tear the liquid-impervious back sheet 2 at the base of the wing-shaped flap W, the top of the corner can be made into a flask shape.

表面層延在部１０は、不透液性裏面シート２の端部と肌との直接の接触を防止するのに十分な範囲とすることが好ましく、具体的には不透液性裏面シート２の外縁より外側に２〜１０mm延在する幅で形成するのが好ましい。なお、表面層延在部１０は、全体に一定の幅で形成する必要はなく、例えばウイング状フラップＷの付け根において他の部分より幅広に形成するなど、幅広の部分と幅狭の部分が混在していても良い。 The surface layer extending part 10 is preferably in a range sufficient to prevent direct contact between the end of the liquid-impermeable back sheet 2 and the skin. Specifically, the liquid-impermeable back sheet 2 It is preferable to form it with a width extending 2 to 10 mm outward from the outer edge. The surface layer extending portion 10 does not need to be formed with a constant width as a whole. For example, the surface layer extending portion 10 is formed wider than the other portions at the base of the wing-shaped flap W, and a wide portion and a narrow portion are mixed. You may do it.

不透液性裏面シート２を吸収体４の外縁より外側に延在させる長さは、ウイング状フラップＷの折返し線ＲＬがなるべく内側に位置できるようにするとともに、フラップ部において表面層との十分な接合領域を確保するため、図３に示されるように、ウイング状フラップＷの付け根のナプキン幅方向幅が極小となる部分でＳ１＝５〜１０mm、生理用ナプキン１の前後端部でＳ２＝１０〜１５mmとすることが好ましい。 The length of the liquid-impervious back sheet 2 that extends outward from the outer edge of the absorbent body 4 is such that the fold line RL of the wing-shaped flap W can be positioned as much as possible inside, and the flap portion is sufficient with the surface layer. 3, in order to secure a proper joint area, as shown in FIG. 3, S1 = 5 to 10 mm at the portion where the width in the napkin width direction of the base of the wing-shaped flap W is minimal, and S2 = at the front and rear ends of the sanitary napkin 1 It is preferable to set it as 10-15 mm.

図７に示されるように、予め製造された吸収体４の下面に、裏面材供給ドラム２０から送り出される連続状の不透液性裏面シート２が導入されるとともに、吸収体４の上面に、セカンドシート供給ドラム２１から送り出される連続状のセカンドシート６と、表面材供給ドラム２２から送り出される連続状の表面シート３とが導入され、第１製品カッター２３により裏面シート２の外形線に沿って裏面シート２、吸収体４、セカンドシート６及び表面シート３の積層体（図８参照）に裁断された後、次の製造工程へ搬送される。 As shown in FIG. 7, the continuous liquid-impermeable back sheet 2 fed from the back material supply drum 20 is introduced to the lower surface of the absorber 4 manufactured in advance, and the upper surface of the absorber 4 is The continuous second sheet 6 fed out from the second sheet supply drum 21 and the continuous topsheet 3 fed out from the surface material supply drum 22 are introduced, and along the outline of the back sheet 2 by the first product cutter 23. After being cut into a laminate (see FIG. 8) of the back sheet 2, the absorber 4, the second sheet 6, and the top sheet 3, the sheet is conveyed to the next manufacturing process.

図９に示されるように、前記積層体の上面の両側部にそれぞれ、サイド不織布供給ドラム（図示せず）から送り出される連続状のサイド不織布７が導入される。 As shown in FIG. 9, continuous side nonwoven fabrics 7 fed from a side nonwoven fabric supply drum (not shown) are introduced into both side portions of the upper surface of the laminate.

前記連続状のサイド不織布７は、図９に示されるように、積層体の幅方向外縁の外側から幅方向中心側に向けて配設されるとともに、予め、ライン幅方向中心側で外側に折り返されるとともに、その折り返し端部で更に折り返されることにより少なくとも透液性表面シート３と接着する部分までが二重シートとされ、この二重シート内部の折り返し端部側に２本の弾性伸縮部材８、８が配設されている。また、ライン幅方向中心側で折り返された内側には、生理用ナプキン１の前後方向端部に対応する位置であり、且つウイング状フラップＷの付け根の外形線よりナプキン幅方向中心側に対応する位置でサイド不織布７、７同士をホットメルトなどの接着剤によって接着した接着部１１、１１が設けられている。 As shown in FIG. 9, the continuous side nonwoven fabric 7 is arranged from the outer side of the outer edge in the width direction toward the center side in the width direction, and is folded in advance outward at the center side in the line width direction. In addition, by further folding back at the folded end portion, at least the portion that adheres to the liquid-permeable surface sheet 3 is a double sheet, and two elastic elastic members 8 are provided on the folded end portion side inside the double sheet. , 8 are arranged. Further, on the inner side folded back at the center side in the line width direction, it is a position corresponding to the front-rear direction end of the sanitary napkin 1, and corresponds to the center side in the napkin width direction from the outline of the base of the wing-shaped flap W. Adhesive portions 11 and 11 are provided in which the side nonwoven fabrics 7 and 7 are bonded to each other by an adhesive such as hot melt.

その後、図１０及び図１１に示されるように、立体ギャザー起立手段２５によって強制的に立体ギャザーＢＳ部分を起立させた状態で、この起立した立体ギャザーＢＳ、ＢＳ部分が嵌り込むようにドラム周面の円周方向に沿って２条の溝２６ａ、２６ａが形成されるとともに、この溝２６ａを除いたエンボスドラムの周面に不透液性裏面シート２の外形線に沿って凸状のエンボス凸部２６ｂが形成されたエンボスドラム２６によって、不透液性裏面シート２のほぼ全周を熱圧着する。熱圧着した後の積層体を図１２に示す。 Thereafter, as shown in FIG. 10 and FIG. 11, in the state where the solid gather BS portion is forcibly raised by the solid gather standing means 25, the drum circumferential surface so that the raised solid gather BS and BS portions are fitted. Are formed on the circumferential surface of the embossing drum excluding the groove 26a along the contour line of the liquid-impermeable back sheet 2. With the embossing drum 26 in which the portion 26b is formed, almost the entire circumference of the liquid-impermeable back sheet 2 is thermocompression bonded. The laminated body after thermocompression bonding is shown in FIG.

熱圧着部１２は、図１２に示されるように、立体ギャザーＢＳを除く生理用ナプキン１のほぼ全周に亘って形成することができる一方で、立体ギャザーＢＳには熱圧着部を形成していないため、立体ギャザーＢＳが熱圧着によって硬化するのが防止できる。 As shown in FIG. 12, the thermocompression bonding part 12 can be formed over almost the entire circumference of the sanitary napkin 1 excluding the three-dimensional gather BS, while the thermocompression bonding part is formed in the three-dimensional gather BS. Therefore, the solid gather BS can be prevented from being hardened by thermocompression bonding.

前記立体ギャザー起立手段２５としては、例えば図１０に示されるように、ライン流れ方向に沿って対向する間隔が漸次狭くなるように配置されたほぼ直立する２枚の板を対向させたものなどによって構成することができる。 As the three-dimensional gather upstanding means 25, for example, as shown in FIG. 10, two substantially upright plates arranged so that the interval facing each other along the line flow direction becomes gradually narrower may be used. Can be configured.

次に、図１３に示されるように、同様の立体ギャザー起立手段２７によって強制的にサイド不織布７の立体ギャザーＢＳ部分を起立させた状態で、この起立した立体ギャザーＢＳ部分が嵌り込むようにドラム周面の幅方向中央部に円周方向に沿って凹部２８ａが形成されるとともに、この凹部２８ａを除いたカッタードラムの周面にナプキン幅方向の外形線に沿って凸状のカッター部２８ｂが形成されたカッタードラム２８（第２製品カッター）によって、サイド不織布７のうちの立体ギャザーＢＳ部分を残してナプキン幅方向両側部をナプキン外形線に沿って裁断する。 Next, as shown in FIG. 13, in a state where the three-dimensional gather BS portion of the side nonwoven fabric 7 is forcibly raised by the same three-dimensional gather standing means 27, the drum is so fitted that the raised three-dimensional gather BS portion is fitted. A concave portion 28a is formed along the circumferential direction at the central portion in the width direction of the peripheral surface, and a convex cutter portion 28b is formed along the outline of the napkin width direction on the peripheral surface of the cutter drum excluding the concave portion 28a. The formed cutter drum 28 (second product cutter) cuts both sides of the napkin width direction along the napkin outline, leaving the three-dimensional gathered BS portion of the side nonwoven fabric 7.

その後、図１４に示されるように、サイド不織布７の立体ギャザーＢＳ部分を積層体の表面側に積層し、立体ギャザーＢＳ部分のナプキン前後端部の幅方向外側に対応する接合部１３でナプキン１の表面側に接合した状態で、第３製品カッター（図示せず）によってサイド不織布７の立体ギャザーＢＳ部分をナプキン外形線に沿って裁断する。裁断後の生理用ナプキン１を図１５に示す。 After that, as shown in FIG. 14, the three-dimensional gathered BS portion of the side nonwoven fabric 7 is laminated on the surface side of the laminate, and the napkin 1 is joined at the joint portion 13 corresponding to the widthwise outer side of the front and rear end portions of the three-dimensional gathered BS portion. In a state of being joined to the surface side of the sheet, a three-dimensional gather BS portion of the side nonwoven fabric 7 is cut along a napkin outline by a third product cutter (not shown). The sanitary napkin 1 after cutting is shown in FIG.

〔他の形態例〕
(1)生理用ナプキン１の製造において、上記形態例では、予め第１製品カッター２３により裏面シート２の外形線に沿って裏面シート２、吸収体４、セカンドシート６及び表面シート３の積層体に裁断した後、連続状のサイド不織布７を導入していたが、裏面シート２のみを外形線に沿って裁断し、この裏面シート２と吸収体４との積層体に対し、連続状のセカンドシート６及び表面シート３を導入した上で連続状のサイド不織布７を導入し、前記第２製品カッター及び第３製品カッターで裁断する際に、サイド不織布７とともに連続状のセカンドシート６及び表面シート３を裁断するようにしてもよい。 [Other examples]
(1) In the manufacture of the sanitary napkin 1, in the above embodiment, the first product cutter 23 previously laminates the back sheet 2, the absorbent body 4, the second sheet 6, and the top sheet 3 along the outline of the back sheet 2. After the cutting, the continuous side nonwoven fabric 7 was introduced. However, only the back sheet 2 was cut along the outer shape line, and the continuous second was formed on the laminate of the back sheet 2 and the absorbent body 4. When the continuous side nonwoven fabric 7 is introduced after the sheet 6 and the top sheet 3 are introduced and cut with the second product cutter and the third product cutter, the continuous second sheet 6 and the top sheet together with the side nonwoven fabric 7 3 may be cut.

(2)上記形態例では、立体ギャザーＢＳは、生理用ナプキン１の幅方向外縁から幅方向中心側に向けて配設されたサイド不織布７を幅方向中心側で外側へ折り返すことによって形成していたが、サイド不織布７をナプキン１の幅方向外縁から幅方向中心側に向けて配設するまでとし、このサイド不織布７とは別体の素材によって立体ギャザーＢＳを形成するようにしてもよい。この場合、立体ギャザー形成用不織布の基端側（固定部）は、サイド不織布７と透液性表面シート３との間に介在させ固定することが好ましい。また、この場合、立体ギャザー形成用不織布として、素材の曲げ剛性がサイド不織布７より相対的に小さいものを使用することが好ましい。これによって、ウイング状フラップＷの付け根において、不透液性裏面シート２の折り曲げ端縁に加え、透液性表面シート３の折り曲げ端縁も肌に直接当たらなくなるため、更に肌当たりを良好にすることができる。 (2) In the above embodiment, the three-dimensional gather BS is formed by folding the side nonwoven fabric 7 disposed from the outer edge of the sanitary napkin 1 toward the center in the width direction outward at the center in the width direction. However, the side nonwoven fabric 7 may be disposed from the outer edge in the width direction of the napkin 1 toward the center in the width direction, and the three-dimensional gather BS may be formed of a material separate from the side nonwoven fabric 7. In this case, it is preferable that the base end side (fixing portion) of the three-dimensional gather forming nonwoven fabric is interposed and fixed between the side nonwoven fabric 7 and the liquid-permeable surface sheet 3. In this case, it is preferable to use a three-dimensional gather-forming non-woven fabric having a material whose bending rigidity is relatively smaller than that of the side non-woven fabric 7. As a result, in addition to the folded edge of the liquid-impervious back sheet 2 at the base of the wing-shaped flap W, the folded edge of the liquid-permeable surface sheet 3 does not directly contact the skin. be able to.
