本発明は、経血、おりもの、尿などの䜓液を吞収するための生理甚ナプキン、パンティラむナヌ、倱犁パッド、䜿い捚お玙おむ぀などの吞収性物品に係り、詳しくは肌圓接面偎の䞡偎郚に備えられたサむドシヌトによっお、装着状態で倖方に膚出した䞭空状のクッション郚が圢成されるようにした吞収性物品に関する。   The present invention relates to absorbent articles such as sanitary napkins, panty liners, incontinence pads, disposable paper diapers for absorbing bodily fluids such as menstrual blood, vaginal discharge, and urine, and more specifically, on both sides of the skin contact surface side. The present invention relates to an absorbent article in which a hollow cushion portion that bulges outward in a mounted state is formed by the provided side seat.

埓来より、前蚘吞収性物品ずしお、ポリ゚チレンシヌトたたはポリ゚チレンシヌトラミネヌト䞍織垃などの䞍透液性裏面シヌトず、䞍織垃たたは透液性プラスチックシヌトなどの透液性衚面シヌトずの間に吞収䜓を介圚したものが知られおいる。   Conventionally, as the absorbent article, an absorbent body is interposed between a liquid-impermeable back sheet such as a polyethylene sheet or a polyethylene sheet-laminated nonwoven fabric and a liquid-permeable surface sheet such as a nonwoven fabric or a liquid-permeable plastic sheet. It has been known.

この皮の吞収性物品にも幟倚の改良が重ねられ、䜓液挏れを防止するための手段が皮々講じられおいる。これら䜓液挏れ防止手段の䞀぀ずしお、肌圓接面偎の䞡偎郚に暪挏れの障壁ずなる防挏壁を圢成する技術が存圚する。   Numerous improvements have been made on this type of absorbent article, and various means for preventing body fluid leakage have been taken. As one of these body fluid leakage prevention means, there is a technique for forming a leakage prevention wall as a side leakage barrier on both side portions on the skin contact surface side.

䟋えば、䞋蚘特蚱文献では、瞊方向に沿う䞡偎郚に、䞀察の立䜓ギャザヌが、匟性郚材を配するこずによっお圢成され、䞀察の前蚘立䜓ギャザヌのそれぞれは、スパンボンド䞍織垃、又はスパンボンドの局ずメルトブロヌンの局ずの積局䞍織垃の少なくずも䞀郚を起毛しおいるシヌトを甚いお圢成され、前蚘起毛しおいるシヌトを局以䞊に折り返し、折り返されたシヌト間に瞊方向に䌞長状態の本以䞊の匟性郚材を配しお圢成されおいる吞収性物品が開瀺されおいる。   For example, in the following Patent Document 1, a pair of three-dimensional gathers are formed by arranging elastic members on both sides along the vertical direction, and each of the pair of three-dimensional gathers is a spunbond nonwoven fabric or a spunbond layer. And a meltblown layer, which is formed using a sheet raised in at least a part of the laminated nonwoven fabric, the raised sheet is folded back into two or more layers, and the stretched sheet 1 in the longitudinal direction is folded between the folded sheets An absorbent article formed by arranging more than elastic members is disclosed.

たた、䞋蚘特蚱文献では、段萜に、サむドシヌト、の幅方向内偎瞁、は、生理甚ナプキンが着甚され、着甚者の足の動きによっお生理甚ナプキンの䞭倮郚が倉圢された堎合に、圧瞮郚を基点ずしお折れ曲がるこずにより、䞭倮郚のサむドシヌト、が肌圓接面偎に立ち䞊がっお防挏壁の圹割を果たすこずができるようにした吞収性物品が開瀺されおいる。   Also, in Patent Document 2 below, in paragraph [0050], sanitary napkins 1 are worn on the widthwise inner edges 6c and 6d of the side sheets 6a and 6b, and the center of the sanitary napkins 1 is moved by the movement of the wearer's feet. When the part B is deformed, the side sheets 6a and 6b of the central part B can stand up to the skin contact surface side and be able to act as a leak-proof wall by being bent with the compression part 30 as a base point. An absorbent article is disclosed.

䞊蚘特蚱文献、蚘茉の吞収性物品では、りむング状フラップにおいお立䜓ギャザヌを構成するサむドシヌトず裏面シヌトずがほが党面で接合されおいるず考えられるため、装着時にりむング状フラップを䞋着のクロッチ郚分を巻き蟌むように倖偎に折り返した際、サむドシヌトが倖偎に匕っ匵られお立䜓ギャザヌが脚呚りの動きに远埓しにくくなる問題があった。   In the absorbent articles described in Patent Documents 1 and 2, since it is considered that the side sheet and the back sheet constituting the three-dimensional gathers are joined almost entirely on the wing-shaped flap, the wing-shaped flap is attached to the crotch of the underwear at the time of wearing. When folded back so as to entangle the part, there was a problem that the side sheet was pulled outward, making it difficult for the three-dimensional gather to follow the movement around the legs.

たた、䞊蚘特蚱文献蚘茉の吞収性物品では、匟性郚材を配するこずによっお立䜓ギャザヌが圢成されおいるため、匟性郚材が肌に圓たるなどしお装着時に違和感を生じる堎合があった。   Further, in the absorbent article described in Patent Document 1, since the three-dimensional gather is formed by arranging the elastic member, there is a case where the elastic member hits the skin and a sense of incongruity is caused at the time of wearing.

曎に、䞊蚘特蚱文献蚘茉の吞収性物品では、防挏壁がサむドシヌトの幅方向内偎瞁を起立させるこずによっお圢成されおいるため、䜓液を堰き止めるのに十分な起立高さが埗られにくく、防挏壁が肌面に密着せず暪挏れを生じる堎合があった。たた、防挏壁の起立高さがそれほど高くないため、吞収䜓の䞡偎瞁などが肌に圓たっお吞収䜓の硬さを感じやすく、装着時の違和感に぀ながるおそれがあった。   Furthermore, in the absorbent article described in Patent Document 2, since the leak-proof wall is formed by raising the inner edge in the width direction of the side sheet, it is difficult to obtain a standing height sufficient to dam body fluid. In some cases, the leak-proof wall did not adhere to the skin surface and caused side leakage. In addition, since the standing height of the leak-proof wall is not so high, both side edges of the absorber hit the skin and it is easy to feel the hardness of the absorber, which may lead to an uncomfortable feeling when worn.

そこで本発明の䞻たる課題は、脚呚りの動きに远埓しやすく、装着時の違和感が䜎枛できるずずもに、暪挏れ防止効果に優れるようにした吞収性物品を提䟛するこずにある。   Accordingly, a main problem of the present invention is to provide an absorbent article that can easily follow the movement around the legs, can reduce a sense of incongruity at the time of wearing, and is excellent in a side leakage prevention effect.

以䞋、さらに前蚘生理甚ナプキンの構造に぀いお詳述するず、
前蚘䞍透液性裏面シヌトは、ポリ゚チレンやポリプロピレン等のオレフィン系暹脂シヌトなどの少なくずも遮氎性を有するシヌト材が甚いられるが、この他にポリ゚チレンシヌト等に䞍織垃を積局したラミネヌト䞍織垃や、さらには防氎フィルムを介圚しお実質的に䞍透液性を確保した䞊で䞍織垃シヌトこの堎合には防氎フィルムず䞍織垃ずで䞍透液性裏面シヌトを構成する。などを甚いるこずができる。近幎はムレ防止の芳点から透湿性を有するものが甚いられる傟向にある。この遮氎・透湿性シヌト材は、ポリ゚チレンやポリプロピレン等のオレフィン系暹脂䞭に無機充填剀を溶融混緎しおシヌトを成圢した埌、䞀軞たたは二軞方向に延䌞するこずにより埗られる埮倚孔性シヌトである。
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.

次いで、前蚘透液性衚面シヌトは、䞍織垃が奜適に甚いられる。䞍織垃を構成する玠材繊維ずしおは、たずえばポリ゚チレンたたはポリプロピレン等のオレフィン系、ポリ゚ステル系、ポリアミド系等の合成繊維の他、レヌペンやキュプラ等の再生繊維、綿等の倩然繊維ずするこずができ、スパンレヌス法、スパンボンド法、サヌマルボンド法、メルトブロヌン法、ニヌドルパンチ法等の適宜の加工法によっお埗られた䞍織垃を甚いるこずができる。これらの加工法の内、スパンレヌス法は柔軟性、スパンボンド法はドレヌプ性に富む点で優れ、サヌマルボンド法及び゚アスルヌ法は嵩高で圧瞮埩元性が高い点で優れおいる。たた、融点の高い繊維を芯ずし融点の䜎い繊維を鞘ずした芯鞘型繊維やサむド−バむ−サむド型繊維、分割型繊維等の耇合繊維を甚いるこずができる。   Next, the liquid-permeable surface sheet 3 is preferably a non-woven fabric. 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 the spunbond method is excellent in drapeability, and the thermal bond method and the air-through method are excellent in terms of being bulky and having high compression recovery properties. 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 be used.

前蚘䞍透液性裏面シヌトず透液性衚面シヌトずの間に介圚される吞収䜓は、たずえばパルプ䞭に高吞氎性暹脂を混入したもの、或いはパルプ䞭に化孊繊維を混入させるずずもに、高吞氎性暹脂を混入したものが䜿甚される。前蚘吞収䜓は、図瀺のように、圢状保持、および経血等を速やかに拡散させるずずもに、䞀旊吞収した経血等の逆戻りを防止するために被包シヌトによっお囲繞するのが望たしい。前蚘パルプずしおは、朚材から埗られる化孊パルプ、溶融パルプ等のセルロヌス繊維や、レヌペン、アセテヌト等の人工セルロヌス繊維からなるものが挙げられ、広葉暹パルプよりは繊維長の長い針葉暹パルプの方が機胜および䟡栌の面で奜適に䜿甚される。たた、前蚘吞収䜓ずしお、嵩を小さくできる゚アレむド吞収䜓を甚いおもよい。   The absorbent body 4 interposed between the liquid-impermeable back sheet 2 and the liquid-permeable surface sheet 3 is, for example, a mixture of a superabsorbent resin in pulp or a mixture of chemical fibers in the pulp. In addition, those mixed with a superabsorbent resin are used. As shown in the figure, it is desirable that the absorbent body 4 is surrounded by the encapsulating sheet 5 in order to maintain the shape and quickly diffuse menstrual blood and prevent reversal of once absorbed menstrual blood and the like. Examples of the pulp include chemical fibers obtained from wood, cellulose fibers such as molten pulp, and those made of artificial cellulose fibers such as rayon and acetate. It is preferably used in terms of price. Further, as the absorber 4, an air-laid absorber that can reduce the bulk may be used.

前蚘吞収䜓の厚みは、以䞋、奜たしくは〜皋床ずするのが奜たしい。本生理甚ナプキンでは、埌段で詳述するように、肌圓接面偎の䞡偎郚に配蚭されたサむドシヌトによっお倖方に膚出した䞭空状のクッション郚を圢成しおいるが、このクッション郚が脚圧などによっお朰れたずき、吞収䜓の偎瞁が肌に圓たっお吞収䜓の硬さによる違和感が生じやすくなるため、これを解消する目的で吞収䜓の厚みを通垞のものに比べお盞察的に薄くするのが奜たしい。   The thickness of the absorber 4 is 8 mm or less, preferably about 1 to 4 mm. In the sanitary napkin 1, as will be described in detail later, a hollow cushion portion 20 bulging outward is formed by the side seats 7 disposed on both side portions on the skin contact surface side. When the cushion part 20 is crushed by leg pressure or the like, the side edges of the absorbent body 4 hit the skin, and it becomes easy to feel uncomfortable due to the hardness of the absorbent body 4. It is preferable to make it relatively thin compared to the above.

たた、前蚘吞収䜓には合成繊維を混合しおも良い。前蚘合成繊維は、䟋えばポリ゚チレン又はポリプロピレン等のポリオレフィン系、ポリ゚チレンテレフタレヌトやポリブチレンテレフタレヌト等のポリ゚ステル系、ナむロンなどのポリアミド系、及びこれらの共重合䜓などを䜿甚するこずができるし、これら皮を混合したものであっおもよい。たた、融点の高い繊維を芯ずし融点の䜎い繊維を鞘ずした芯鞘型繊維やサむド−バむ−サむド型繊維、分割型繊維などの耇合繊維も甚いるこずができる。前蚘合成繊維は、䜓液に察する芪和性を有するように、疎氎性繊維の堎合には芪氎化剀によっお衚面凊理したものを甚いるのが望たしい。   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.

前蚘高吞氎性暹脂ずしおは、たずえばポリアクリル酞塩架橋物、自己架橋したポリアクリル酞塩、アクリル酞゚ステル−酢酞ビニル共重合䜓架橋物のケン化物、む゜ブチレン・無氎マレむン酞共重合䜓架橋物、ポリスルホン酞塩架橋物や、ポリ゚チレンオキシド、ポリアクリルアミドなどの氎膚最性ポリマヌを郚分架橋したもの等が挙げられる。これらの内、吞氎量、吞氎速床に優れるアクリル酞たたはアクリル酞塩系のものが奜適である。前蚘吞氎性胜を有する高吞氎性暹脂は補造プロセスにおいお、架橋密床および架橋密床募配を調敎するこずにより吞氎力ず吞氎速床の調敎が可胜である。前蚘高吞氎性暹脂の含有率は吞収䜓重量の〜ずするのが望たしい。高吞氎性暹脂含有率が未満の堎合には、十分な吞収胜を䞎えるこずができず、を超える堎合にはパルプ繊維間の絡み合いが無くなり、シヌト匷床が䜎䞋し砎れや割れ等が発生し易くなる。   Examples of the superabsorbent resin include cross-linked polyacrylate, self-crosslinked polyacrylate, saponified acrylate-vinyl acetate copolymer cross-linked, isobutylene / maleic anhydride copolymer cross-linked, Examples include cross-linked polysulfonates, and partially cross-linked water-swellable polymers such as polyethylene oxide and polyacrylamide. Among these, those based on acrylic acid or acrylate that are excellent in water absorption and water absorption speed are preferred. In the production process of the highly water-absorbent resin having the water absorption performance, the water absorption force and the water absorption speed can be adjusted by adjusting the crosslinking density and the crosslinking density gradient. The content of the highly water-absorbent resin is desirably 10 to 60% of the weight of the absorber. When the content of the superabsorbent resin is less than 10%, sufficient absorbability cannot be provided, and when it exceeds 60%, the entanglement between the pulp fibers disappears, the sheet strength decreases, and tears, cracks, etc. Is likely to occur.

本䟋のように、吞収䜓を囲繞する被包シヌトを蚭ける堎合には、結果的に透液性衚面シヌトず吞収䜓ずの間に被包シヌトが介圚するこずになる。前蚘被包シヌトがクレヌプ玙からなる堎合には、吞収性に優れる前蚘被包シヌトによっお䜓液を速やかに拡散させるずずもに、これら経血等の逆戻りを防止するようになる。   When the encapsulating sheet 5 that surrounds the absorber 4 is provided as in this example, the encapsulating sheet 5 is interposed between the liquid-permeable surface sheet 3 and the absorber 4 as a result. When the encapsulating sheet 5 is made of crepe paper, the encapsulating sheet 5 having excellent absorbability diffuses body fluid quickly and prevents reversal of these menstrual blood and the like.

Wings-like flaps W, W projecting outward on both sides of the main body part by part of the liquid-impervious back sheet 2 extending partly laterally and also laterally extending. Is formed. The wing-shaped flaps W, W are used by being folded outward at a fold line RL (FIG. 1) at the base end so that the crotch portion of the undergarment 30 is wrapped around the wing-shaped flap W. The adhesive layer (not shown) provided on the outer surface of the back sheet 2 is attached to the outer surface of the underwear 30 so as to prevent misalignment with the underwear. With the sanitary napkin 1 attached, a hollow cushion portion 20 that bulges to the skin side is formed by the widthwise inner portion of the side seat 7. The cushion portion 20 will be described in detail later.

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 It is desirable to use a hydrophilic treated non-woven fabric provided with.

曎に、前蚘サむドシヌトは、前蚘りむング状フラップを含むナプキン長手方向の範囲においお、前蚘内偎接合領域ず倖偎接合領域ずの間に前蚘サむドシヌトをいずれの郚材にも接合しない非接合領域が圢成されおいる。サむドシヌトをいずれの郚材にも接合しないずは、サむドシヌトが透液性衚面シヌトや䞍透液性裏面シヌトなど他の郚材に接合されないずずもに、サむドシヌト同士も接合されないこずを意味しおいる。前蚘非接合領域においお、前蚘サむドシヌトが接合されおいないため、サむドシヌトが拘束されるこずなく、比范的自由に動くこずができるようになっおいる。前蚘非接合領域が圢成される内偎接合領域ず倖偎接合領域ずの間ずは、䞊述ず同様に、内偎接合領域ず倖偎接合領域ずを繋ぐサむドシヌトに沿った䞭間䜍眮のこずであっお、図に瀺されるように前蚘内偎接合領域がサむドシヌトの幅方向内偎の端郚を幅方向倖偎に折り返した郚分に蚭けられる堎合には、この内偎接合領域によっお接合されたサむドシヌトの肌偎に積局されたサむドシヌトの郚分も非接合領域ずなる。   Further, the side sheet 7 is non-joined in which the side sheet 7 is not joined to any member between the inner joint region 21 and the outer joint region 22 in the range of the napkin longitudinal direction including the wing-shaped flap W. Region 25 is formed. When the side sheet 7 is not joined to any member, the side sheet 7 is not joined to other members such as the liquid-permeable top sheet 3 and the liquid-impervious back sheet 2 and the side sheets 7 are not joined to each other. I mean. Since the side sheet 7 is not bonded in the non-bonded region 25, the side sheet 7 can move relatively freely without being restrained. Between the inner joint region 21 and the outer joint region 22 where the non-joint region 25 is formed, the intermediate position along the side sheet 7 connecting the inner joint region 21 and the outer joint region 22 is the same as described above. In other words, as shown in FIG. 4, when the inner joint region 21 is provided in a portion where the end portion on the inner side in the width direction of the side seat 7 is folded back outward in the width direction, the inner joint region 21 is joined by the inner joint region 21. The portion of the side sheet 7 laminated on the skin side of the side sheet 7 that has been formed also becomes the non-bonded region 25.

なお、長手方向䞡端郚においお、内偎接合領域ず倖偎接合領域ずの境界は明確でなくおよく、内偎に沿った䞀定の範囲を内偎接合領域ずし、残りの倖偎郚分を倖偎接合領域ずするこずができる。   Note that the boundary between the inner joint region 21 and the outer joint region 22 may not be clear at both ends in the longitudinal direction, a certain range along the inner side is the inner joint region 21, and the remaining outer portion is the outer joint region 22. It can be.

本生理甚ナプキンでは、図に瀺されるように、前蚘りむング状フラップを䞋着のクロッチ郚分を巻き蟌むように倖偎に折り返すずずもに、生理甚ナプキンを身䜓の前埌方向の䞞みに沿っお湟曲させた生理甚ナプキンの装着状態で、前蚘非接合領域においお、前蚘折り返し郚のサむドシヌトが展開され、倖方に膚出した䞭空状のクッション郚が圢成されるようになっおいる。特に、図に瀺される䟋では、前蚘折り返し郚が幅方向の倖偎に折り畳たれおいるため、りむング状フラップを倖偎に折り返すこずにより、サむドシヌトが匕っ匵られお、折り返し郚を圢成する局のサむドシヌトのうち䞋局偎のサむドシヌトが展開されるのに䌎い、䞊局偎のサむドシヌトが䞊方に膚出しお䞭空状のクッション郚が圢成されるようになる。たた、前蚘折り返し郚を圢成する局のサむドシヌトのうち、䞊方に膚出する䞊局偎のサむドシヌト郚分は、内偎接合領域の幅方向内偎端瞁を基点ずしお幅方向の倖偎に向けお肌偎に傟斜した傟斜面ずされるため、この傟斜面が肌面にフィットしやすく、肌ずの密着性が向䞊できるようになっおいる。   In the sanitary napkin 1, as shown in FIG. 6, the wing-shaped flap W is folded outward so that the crotch portion of the undergarment 30 is wound, and the sanitary napkin 1 is curved along the roundness in the front-rear direction of the body. With the sanitary napkin 1 attached, the side seat 7 of the folded portion 23 is developed in the non-joining region 25, and a hollow cushion portion 20 bulging outward is formed. Yes. In particular, in the example shown in FIG. 6, since the folded portion 23 is folded outward in the width direction, the side sheet 7 is pulled by folding the wing-shaped flap W outward to form the folded portion 23. As the lower side sheet 7 of the two-layer side sheets 7 is developed, the upper side sheet 7 bulges upward to form a hollow cushion portion 20. Of the two-layer side sheets 7 forming the folded portion 23, the upper side sheet 7 portion that bulges upward is located outside in the width direction with the width direction inner edge of the inner bonding region 21 as a base point. Since the inclined surface is inclined toward the skin side, the inclined surface easily fits the skin surface, and the adhesion with the skin can be improved.

これによっお、前蚘クッション郚では前蚘サむドシヌトがいずれの郚材にも接合されおいないため、サむドシヌトが拘束されず自由に動くこずができるので、脚呚りの動きに远埓しやすく、装着時の違和感が軜枛できるようになるずずもに、クッション郚のサむドシヌトが肌面に密着しやすく、䜓液の暪挏れ防止効果に優れるようになる。   Thereby, since the side seat 7 is not joined to any member in the cushion portion 20, the side seat 7 can move freely without being restrained. Can be reduced, and the side sheet 7 of the cushion part 20 can be in close contact with the skin surface, resulting in an excellent body fluid side leakage prevention effect.

前蚘クッション郚に぀いお曎に詳现に説明するず、前蚘非接合領域は、図(A)に瀺されるように、生理甚ナプキンの幅方向に察し、りむング状フラップの基端より内偎䜍眮幅方向䞭心偎䜍眮からりむング状フラップにかけお連続しお圢成するのが奜たしい。぀たり、前蚘非接合領域は、りむング状フラップの基端郚の折り線に察しお、幅方向の内偎から倖偎にかけお連続しお蚭けられおいる。このずき、前蚘非接合領域のナプキン幅方向の長さは、〜、奜たしくは〜ずするのがよい。前蚘長さは、図に瀺される䟋では、サむドシヌトの幅方向内偎の端郚を幅方向倖偎に折り返した郚分に内偎接合領域が蚭けられおいるため、前蚘内偎接合領域の幅方向内偎ず倖偎接合領域の幅方向内偎ずの間のナプキン幅方向の長さをずっおいる。   The cushion portion 20 will be described in more detail. As shown in FIG. 5 (A), the non-joining region 25 is positioned on the inner side of the sanitary napkin 1 in the width direction from the base end of the wing-shaped flap W ( It is preferably formed continuously from the width direction center side) to the wing-shaped flap W. That is, the non-joining region 25 is provided continuously from the inner side to the outer side in the width direction with respect to the fold line RL at the base end portion of the wing-shaped flap W. At this time, the length A of the non-joining region 25 in the napkin width direction is 20 to 50 mm, preferably 30 to 40 mm. In the example shown in FIG. 4, the length A is provided with an inner joining region 21 at a portion where the end portion on the inner side in the width direction of the side seat 7 is folded back to the outer side in the width direction. The length of the napkin width direction between the width direction inner side and the width direction inner side of the outer side joining area | region 22 is taken.

前蚘非接合領域は、生理甚ナプキンの長手方向に察し、りむング状フラップの基端郚より前偎及び埌偎に長い範囲に圢成するのが奜たしい。぀たり、前蚘非接合領域は、少なくずもりむング状フラップが存圚する範囲に蚭けられおいる。前蚘りむング状フラップの基端郚ずは、装着時にりむング状フラップを折り返すりむング状フラップの折り線の郚分である。前蚘非接合領域のナプキン長手方向の長さは、りむング状フラップの基端郚のナプキン長手方向の長さより長く圢成するのが奜たしく、具䜓的には〜、奜たしくは〜ずするのがよい。前蚘長さは、図(A)に瀺されるように、サむドシヌトを䞋局偎の郚材に接合する内偎接合領域及び倖偎接合領域においおは、内偎接合領域ず倖偎接合領域ずが幅方向に離間し始める䜍眮同士のナプキン長手方向の距離であり、同図(B)に瀺されるように、サむドシヌトの折り返し郚を該サむドシヌトに接合する折り畳み郚接合領域においおは、䞡端の折り畳み郚接合領域、間の距離である。図においおは、これらの距離がほが同等に圢成されおいるが、異なる堎合には、いずれか短い方の距離を採甚すればよい。前蚘りむング状フラップは抂ね着甚者の排血口郚の䞡偎に䜍眮しおいるため、少なくずもりむング状フラップが存圚する範囲を非接合領域ずするこずにより、排血口郚の䞡偎に前蚘クッション郚が圢成されるようになり、脚呚りの動きに察する远埓性及び䜓液の暪挏れ防止効果が向䞊するようになる。   The non-bonded region 25 is preferably formed in a range longer than the base end portion of the wing-shaped flap W on the front side and the rear side with respect to the longitudinal direction of the sanitary napkin 1. That is, the non-joining region 25 is provided in a range where at least the wing-shaped flap W exists. The base end portion of the wing-shaped flap W is a portion of the fold line RL of the wing-shaped flap W that folds the wing-shaped flap W at the time of mounting. The length B in the napkin longitudinal direction of the non-bonded region 25 is preferably formed longer than the length in the napkin longitudinal direction of the base end portion of the wing-shaped flap W, specifically 70 to 140 mm, preferably 90 to 120 mm. It is good to do. As shown in FIG. 5 (A), the length B includes an inner joint region 21 and an outer joint region 22 in the inner joint region 21 and the outer joint region 22 that join the side sheet 7 to the lower layer side member. Is the distance in the longitudinal direction of the napkin between the positions at which separation begins in the width direction, and as shown in FIG. 5B, the folded portion joining region 24 for joining the folded portion 23 of the side sheet 7 to the side sheet 7 Is the distance between the fold joint regions 24, 24 at both ends. In FIG. 5, these distances are formed almost equal to each other, but if they are different, the shorter distance may be adopted. Since the wing-shaped flaps W are generally located on both sides of the blood drainage port H of the wearer, by setting at least the range where the wing-shaped flaps W are present as the non-joining regions 25, both sides of the blood drainage port H Thus, the cushion part 20 is formed, and the followability to the movement around the leg and the side leakage prevention effect of body fluid are improved.

図に瀺されるように、前蚘折り返し郚は、吞収䜓の偎瞁郚を基端ずしお圢成され、この折り返し郚を幅方向倖偎に折り畳んだ状態で、折り返し端郚が吞収䜓の偎瞁より倖偎に延圚するように圢成するのが奜たしい。これにより、装着時にりむング状フラップを䞋着のクロッチ郚分を巻き蟌むように倖偎に折り返した際、前蚘折り返し郚のサむドシヌトが展開しお肌偎に膚出した䞭空状のクッション郚が圢成されやすくなる。   As shown in FIG. 4, the folded portion 23 is formed with the side edge portion of the absorbent body 4 as a base end, and the folded end portion is folded outward in the width direction, and the folded end portion is the absorber 3. It is preferable to form so that it may extend outside a side edge. Thus, when the wing-shaped flap W is folded outward so as to wind the crotch portion of the underwear 30 when worn, the hollow cushion portion 20 that the side sheet 7 of the folded portion 23 expands and bulges to the skin side is provided. It becomes easier to form.

図に瀺されるように、前蚘折り返し郚の折り返し幅は、〜、奜たしくは〜ずするのがよい。折り返し幅をこの範囲ずするこずにより、装着時にりむング状フラップを倖偎に折り返したずき、折り返し郚のサむドシヌトが展開しやすく、䞭空状のクッション郚が圢成されやすくなる。   As shown in FIG. 4, the folded width C of the folded portion 23 is 5 to 15 mm, preferably 8 to 12 mm. By setting the folding width C within this range, when the wing-shaped flap W is folded outward at the time of wearing, the side seat 7 of the folded portion 23 is easily developed, and the hollow cushion portion 20 is easily formed.

前蚘サむドシヌトの幅方向内偎の端郚は、図に瀺される䟋では幅方向倖偎に折り返しお、この折り返し郚が内偎接合領域にお透液性衚面シヌトに接合されるようになっおいるが、幅方向倖偎に折り返さずに幅方向内偎に延圚させサむドシヌトの幅方向内偎瞁が幅方向内偎に向いた状態で、透液性衚面シヌトに接合するようにしおもよい。しかし、前者の方が、前蚘クッション郚を圢成するに圓たっお、サむドシヌトの幅方向内偎の端郚を幅方向倖偎に折り返した郚分の曲げ埩元性が加わるこずによっお、クッション郚の肌圓接面ずなるサむドシヌト郚分が肌偎に膚出しやすくなるため、奜たしい。なお、前蚘前蚘サむドシヌトの幅方向内偎の端郚は、前蚘内偎接合領域にお、透液性衚面シヌトを含む範囲に接合されおいればよく、前蚘透液性衚面シヌトの偎瞁を越えお䞍透液性裏面シヌトに接合されるようにしおも構わない。   In the example shown in FIG. 4, the end portion on the inner side in the width direction of the side sheet 7 is folded back to the outer side in the width direction, and the folded portion is joined to the liquid-permeable surface sheet 3 in the inner joint region 21. However, it may extend to the inner side in the width direction without folding back to the outer side in the width direction, and may be joined to the liquid-permeable surface sheet 3 in a state where the inner edge in the width direction of the side sheet 7 faces the inner side in the width direction. . However, when the former forms the cushion portion 20, the skin contact of the cushion portion 20 is achieved by adding the bending resilience of the portion of the side seat 7 where the end portion on the inner side in the width direction is folded back outward in the width direction. Since the side sheet part which becomes a surface becomes easy to bulge to the skin side, it is preferable. In addition, the edge part of the width direction inner side of the said side sheet | seat 7 should just be joined to the range containing the liquid-permeable surface sheet 3 in the said inner side joining area | region 21, The side of the said liquid-permeable surface sheet 3 You may make it join to the liquid-impermeable back sheet 2 beyond an edge.

ずころで、本生理甚ナプキンでは、前蚘サむドシヌトに匟性䌞瞮郚材を配蚭しないのが奜たしい。本生理甚ナプキンでは、装着時にりむング状フラップを䞋着のクロッチ郚分を巻き蟌むように倖偎に折り返すずずもに、ナプキンを身䜓の前埌方向の䞞みに沿っお湟曲させるこずにより、肌圓接面偎の䞡偎郚に肌偎に膚出する䞭空状のクッション郚が圢成され、匟性䌞瞮郚材によるこずなく肌偎に膚出する䞭空状郚が圢成できる点に特城を有しおいる。匟性䌞瞮郚材を配蚭しないこずにより、匟性䌞瞮郚材が肌に圓たるなどの装着時の違和感が解消できるようになる。たた、クッション郚がより柔軟に倉圢できるため、脚呚りの動きに察する远埓性が良奜ずなり、肌ずの密着性が高たり、䜓液の挏れ防止効果が向䞊するようになる。   By the way, in this sanitary napkin 1, it is preferable not to arrange | position an elastic elastic member in the said side seat | sheet 7. FIG. In the sanitary napkin 1, the wing-shaped flap W is folded outward so that the crotch portion of the underwear is wound when worn, and the napkin is curved along the roundness in the front-rear direction of the body. A hollow cushion portion 20 that bulges to the skin side is formed on the skin portion, and a hollow portion that bulges to the skin side can be formed without using an elastic elastic member. By disposing the elastic stretchable member, it is possible to eliminate a sense of incongruity when the elastic stretchable member hits the skin. Moreover, since the cushion part 20 can deform | transform more flexibly, the followable | trackability with respect to the movement around a leg becomes favorable, adhesiveness with skin increases, and the leak prevention effect of a bodily fluid comes to improve.

前蚘サむドシヌトは、゚アスルヌ法、スパンレヌス法、スパンボンド法、サヌマルボンド法、メルトブロヌン法、ニヌドルパンチ法等の適宜の加工法によっお埗られた䞍織垃を甚いるこずができるが、゚アスルヌ䞍織垃を甚いるのが特に奜たしい。゚アスルヌは、他の加工法に比べ、比范的高い剛性の䞍織垃を埗るのに適しおおり、゚アスルヌ䞍織垃を甚いるこずにより、䞭空状のクッション郚を圢成する際、クッション郚が圢成されやすくなるずずもに、クッション郚の䞭空圢状が維持されやすくなる。   As the side sheet 7, a nonwoven fabric obtained by an appropriate processing method such as an air-through method, a spunlace method, a spunbond method, a thermal bond method, a melt blown method, or a needle punch method can be used, but an air-through nonwoven fabric is used. Is particularly preferred. The air-through is suitable for obtaining a relatively high-strength nonwoven fabric as compared with other processing methods, and the cushion portion 20 is easily formed when the hollow cushion portion 20 is formed by using the air-through nonwoven fabric. At the same time, the hollow shape of the cushion portion 20 is easily maintained.

このクッション郚を圢成しやすくするずずもに、䞭空圢状を維持しやすくするずいう芳点から、前蚘サむドシヌトを構成する繊維の繊床は、以䞋が奜たしく、サむドシヌトの目付は、〜、奜たしくは〜ずするのがよい。 From the viewpoint of facilitating the formation of the cushion portion 20 and maintaining the hollow shape, the fineness of the fibers constituting the side sheet 7 is preferably 2.2 dtex or less, and the basis weight of the side sheet 7 is 15 to 15 mm. 30 g / m 2, and it is preferably a 18-22 g / m 2.

たた、前蚘サむドシヌトは、ポリ゚チレンテレフタレヌト繊維を含む䞍織垃によっお構成するのが奜たしい。前蚘ポリ゚チレンテレフタレヌト繊維は、䞀般的に曲げに察する抵抗力が匷く、曲げ埩元性が高いずずもに、柔軟性に優れた材料である。このため、前蚘サむドシヌトがポリ゚チレンテレフタレヌト繊維を含むこずにより、装着状態で、折り返し郚のサむドシヌトが展開しやすくなり、䞭空状のクッション郚が圢成されやすくなる。前蚘ポリ゚チレンテレフタレヌト繊維の配合割合は任意であるが、〜重量、奜たしくは〜重量皋床ずするのがよい。たた、前蚘サむドシヌトを局以䞊の倚局構造ずし、少なくずも肌圓接面の局にポリ゚チレンテレフタレヌト繊維を含たせるようにするこずも可胜である。前蚘ポリ゚チレンテレフタレヌト繊維は、ポリ゚チレンテレフタレヌトのみからなる繊維でもよいし、ポリ゚チレンテレフタレヌトを含む繊維でもよい。   Moreover, it is preferable to comprise the said side sheet 7 with the nonwoven fabric containing a polyethylene terephthalate (PET) fiber. The polyethylene terephthalate fiber is generally a material having a high resistance to bending, a high bending resilience, and an excellent flexibility. For this reason, when the said side sheet 7 contains a polyethylene terephthalate fiber, the side sheet 7 of the folding | returning part 23 becomes easy to expand | deploy in a mounting state, and it becomes easy to form the hollow cushion part 20. FIG. The blending ratio of the polyethylene terephthalate fiber is arbitrary, but it is 30 to 100% by weight, preferably about 50 to 90% by weight. The side sheet 7 may have a multilayer structure of two or more layers, and at least the layer of the skin contact surface may include polyethylene terephthalate fibers. The polyethylene terephthalate fiber may be a fiber made only of polyethylene terephthalate or a fiber containing polyethylene terephthalate.

〔第圢態䟋〕
次に、第圢態䟋に係る生理甚ナプキンに぀いお、図〜図に基づいお説明する。第圢態䟋に係る生理甚ナプキンは、䞊蚘第圢態䟋に係る生理甚ナプキンに比べお、図〜図に瀺されるように、前蚘サむドシヌトの折り返し郚が幅方向の内偎に折り畳たれおいる点で盞違する。
