Description

本発明は、吸収性物品に関する。 The present invention relates to an absorbent article.

従来より、経血等の排泄物を吸収させるための吸収性物品として、生理用ナプキン、パンティライナー、尿取りパッド等が使用されている。これらの吸収性物品は、経血等の排泄物を吸収し保持する吸収体と、この吸収体の肌当接面側を覆う液透過性の表面シートと、吸収体の着衣側を覆う液不透過性の裏面シートと、を有し、例えば、下着の内面に接着させた状態等で使用される。 Conventionally, sanitary napkins, panty liners, urine absorbing pads and the like have been used as absorbent articles for absorbing excrement such as menstrual blood. These absorbent articles include an absorbent body that absorbs and holds excrement such as menstrual blood, a liquid-permeable surface sheet that covers the skin contact surface side of the absorbent body, and a liquid impermeable material that covers the clothing side of the absorbent body. For example, it is used in a state where it is adhered to the inner surface of the undergarment.

ところで、上記のような吸収性物品は、経血等の排泄物を確実に捕捉するために吸収体を備える吸収領域を着用者の排泄部に密着させて使用することが望まれている。しかしながら、吸収性物品は、元来下着等に取り付けられて使用されるものであるため、着用者の動きの変化に伴い、下着と排泄部との間に相対的な位置ずれを起こし易かった。そして、排泄部と吸収性物品との間に隙間が生じた場合には、例えば、排泄物が表面シートに沿って側方や臀部方向へ流れる場合があり、これにより下着や着衣を汚してしまうという問題があった。 By the way, it is desired that the absorbent article as described above is used in such a manner that an absorption region including an absorbent body is brought into close contact with a wearer's excretion part in order to reliably capture excrement such as menstrual blood. However, since the absorbent article is originally used by being attached to underwear or the like, it is easy to cause a relative positional shift between the underwear and the excretory part in accordance with a change in the wearer's movement. And when a clearance gap arises between an excretion part and an absorptive article, for example, excretion may flow to a side or a buttock direction along a surface sheet, and this will make underwear and clothes dirty. There was a problem.

これに対し、生理用ナプキンの不織布に形成される皺を伸ばすことにより延伸可能とし、延伸させた状態で下着に装着させることにより、着用者の動きの変化に伴う下着や皮膚の伸縮性に追随できるようにした吸収性物品が開示されている（例えば、特許文献１参照）。 On the other hand, it is possible to stretch by stretching the wrinkles formed on the nonwoven fabric of sanitary napkins, and by attaching it to the underwear in a stretched state, it can follow the stretchability of the underwear and skin accompanying changes in the wearer's movement An absorbent article that can be made is disclosed (for example, see Patent Document 1).

また、生理用ナプキンの長手方向における中央部の吸収層を固定し、吸収層の後方自由縁部を自由端とすると共に上方に向けて起立させた吸収性物品が開示されている（例えば、特許文献２参照）。
特表平０７−５０９３８４号公報特開平１１−１０４１６９号公報 In addition, an absorbent article is disclosed in which the absorbent layer at the center in the longitudinal direction of the sanitary napkin is fixed, and the rear free edge of the absorbent layer is a free end and is raised upward (for example, a patent Reference 2).
JP 07-509384 A Japanese Patent Laid-Open No. 11-104169

しかしながら、特許文献１に開示の吸収性物品は、一の連続した吸収体により構成されているため、例えば、臀部のように歩行時に左右方向に動く箇所においては左右方向に対する歪みを生じさせてしまい、着用者に異物感を与えるだけでなく、排泄物等の漏れを生じさせるおそれがあった。 However, since the absorbent article disclosed in Patent Document 1 is composed of one continuous absorbent body, for example, in a portion that moves in the left-right direction during walking, such as a hip, it causes distortion in the left-right direction. In addition to giving the wearer a foreign body sensation, there was a risk of causing excrement leakage.

また、特許文献２に開示の吸収性物品は、後方自由縁部が延伸可能に形成されていないため吸収面積を増やすことができず、例えば、多量の排泄物が排泄された場合には、漏れを生じさせるおそれがあった。 In addition, the absorbent article disclosed in Patent Document 2 cannot increase the absorption area because the rear free edge is not formed to be stretchable. For example, when a large amount of excreta is excreted, leakage occurs. There was a risk of causing.

本発明は、吸収性物品に補助吸収体を設け、補助吸収体を吸収性物品から延出可能に構成することにより、排泄物等の漏れを抑制させることが可能な吸収性物品を提供することを目的とする。 The present invention provides an absorbent article capable of suppressing leakage of excrement and the like by providing an auxiliary absorbent body on the absorbent article and configuring the auxiliary absorbent body so that it can extend from the absorbent article.

A strip-shaped member 10 that connects the napkin body 5 and a cover member 15 that encloses the auxiliary absorbent body 6 and the strip-shaped member 10 are provided.

具体的には、図１から図４に示すように、生理用ナプキン１は、着用者の肌当接面側に設けられ、表面層を構成する液透過性の表面シート部２と、着用者の非肌当接面側に設けられ、裏面層を構成する液不透過性の裏面シート部３と、表面シート部２と裏面シート部３との間に配置され、吸収層を構成する液保持性の第１吸収体部４と、を有する生理用ナプキン本体５と、裏面シート部３の非肌当接面側において、生理用ナプキン本体５の長手方向（ＬＤ）に沿うように摺動可能に設けられる帯状部材１０と、帯状部材１０により生理用ナプキン本体５と連結される補助吸収体６と、生理用ナプキン本体５の非肌当接面側において、補助吸収体６及び帯状部材１０を被包した状態で生理用ナプキン本体５と接合されるカバー部材１５と、を備える。 Specifically, as shown in FIGS. 1 to 4, the sanitary napkin 1 is provided on the skin contact surface side of the wearer, and a liquid-permeable surface sheet portion 2 constituting the surface layer, and the wearer The liquid-impermeable back sheet part 3 that is provided on the non-skin contact surface side and that constitutes the back layer, and is disposed between the top sheet part 2 and the back sheet part 3 to hold the liquid that constitutes the absorption layer The sanitary napkin body 5 having the first absorbent portion 4 and the non-skin contact surface side of the back sheet portion 3 are slidable along the longitudinal direction (LD) of the sanitary napkin body 5. The auxiliary absorbent body 6 and the band-shaped member 10 are provided on the non-skin contact surface side of the sanitary napkin main body 5. A cover member 15 joined to the sanitary napkin body 5 in the encapsulated state. That.

帯状部材１０は、一端側が生理用ナプキン本体５の前方領域（Ｆ）における接合部８において裏面シート部３と接合され、帯状部材１０の他端側は、生理用ナプキン本体５と接合されず、接合部８を起点とする自由端１０ｒとなる。そして、帯状部材１０の自由端１０ｒには、第２吸収体部１００を有する補助吸収体６が連結されている。これにより、補助吸収体６は、帯状部材１０により生理用ナプキン本体５と連結された状態で、補助吸収体６における第２吸収体部１００が生理用ナプキン本体５の外縁から延出しない第１位置から、生理用ナプキン本体５の外縁から延出する第２位置に移動可能となる。 One end of the band-shaped member 10 is bonded to the back sheet 3 at the bonding portion 8 in the front region (F) of the sanitary napkin body 5, and the other end of the band-shaped member 10 is not bonded to the sanitary napkin body 5, The free end 10r starts from the joint 8. And the auxiliary | assistant absorber 6 which has the 2nd absorber part 100 is connected with the free end 10r of the strip | belt-shaped member 10. FIG. Thereby, the auxiliary absorbent body 6 is connected to the sanitary napkin main body 5 by the belt-like member 10, and the second absorbent body portion 100 in the auxiliary absorbent body 6 does not extend from the outer edge of the sanitary napkin main body 5. It becomes possible to move from the position to the second position extending from the outer edge of the sanitary napkin body 5.

また、補助吸収体６の非肌当接面側には、下着５０と係止する係止部９ｒが設けられている。係止部９ｒは、帯状部材１０の非延伸時においてはカバー部材１５に被包されており、帯状部材１０の延伸時に露出可能になるように形成される。カバー部材１５の帯状部材１０側の面には、離型処理された剥離シート２００が接合されており、剥離シート２００は、帯状部材１０が非延伸時のときには係止部９ｒを被覆するように配置される。また、剥離シート２００は、カバー部材１５の端部に設けられる固定部２０１においてカバー部材１５と接合されており、帯状部材１０を延伸させることにより係止部９ｒから剥離されるように構成される。 Further, a locking portion 9 r that locks the underwear 50 is provided on the non-skin contact surface side of the auxiliary absorbent body 6. The locking portion 9r is encapsulated in the cover member 15 when the belt-like member 10 is not stretched, and is formed so as to be exposed when the belt-like member 10 is stretched. A release sheet 200 that has been subjected to a release treatment is bonded to the surface of the cover member 15 on the side of the band-shaped member 10, and the release sheet 200 covers the locking portion 9 r when the band-shaped member 10 is not stretched. Be placed. Further, the release sheet 200 is joined to the cover member 15 at a fixing portion 201 provided at an end portion of the cover member 15, and is configured to be peeled from the locking portion 9 r by extending the belt-like member 10. .

さらに、本実施形態においては、生理用ナプキン１は、表面シート部２及び第１吸収体部４を連続的に圧搾することにより形成される防漏溝部７と、サイドシート１７により形成されるサイドギャザー１６と、を備える。 Furthermore, in this embodiment, the sanitary napkin 1 is a side formed by the leak-proof groove portion 7 formed by continuously squeezing the top sheet portion 2 and the first absorbent body portion 4 and the side sheet 17. And gather 16.

［１．２］生理用ナプキン本体
生理用ナプキン本体５は、略縦長状に形成されると共に、その両側に下着５０に装着するためのいわゆるウイングＷ１、Ｗ２が搭載されている。生理用ナプキン本体５の形状としては、例えば、長方形、楕円型、瓢箪型等を例示できる。なお、本発明においては、着用者の身体及び下着５０の形状に適合する形状であればよい。 [1.2] Sanitary napkin main body The sanitary napkin main body 5 is formed in a substantially vertically long shape, and so-called wings W1 and W2 for mounting on the underwear 50 are mounted on both sides thereof. Examples of the shape of the sanitary napkin main body 5 include a rectangle, an ellipse, and a bowl. In the present invention, any shape that matches the shape of the wearer's body and the underwear 50 may be used.

生理用ナプキン本体５は、生理用ナプキン本体５の幅方向（ＷＤ）における略中央部に略楕円状に形成された液透過領域２０を備える。液透過領域２０は、防漏溝部７により囲まれており、防漏溝部７は、液透過領域２０を区画する。排泄部から排泄される経血等の排泄物は、液透過領域２０における表面シート部２を透過して、第１吸収体部４で吸収される。非肌当接面側に配置される裏面シート部３は液不透過性であるので、排泄物は非肌当接面側には透過せず、第１吸収体部４に吸収された状態で保持されることとなる。また、防漏溝部７は、液透過領域２０を囲むように高圧搾と低圧搾とからなる圧搾部が連続的、若しくは所定間隔に形成されてなり、主に、第１吸収体部４に吸収された経血等の排泄物の漏れを防止すると共に、第１吸収体部４における排泄物の拡散を防止する。 The sanitary napkin body 5 includes a liquid permeable region 20 formed in a substantially elliptical shape at a substantially central portion in the width direction (WD) of the sanitary napkin body 5. The liquid permeable region 20 is surrounded by the leak-proof groove 7, and the leak-proof groove 7 defines the liquid permeable region 20. Excrements such as menstrual blood excreted from the excretion part permeate through the top sheet part 2 in the liquid permeable region 20 and are absorbed by the first absorber part 4. Since the back surface sheet portion 3 disposed on the non-skin contact surface side is liquid-impermeable, excrement does not permeate the non-skin contact surface side and is absorbed by the first absorber 4. Will be held. Further, the leakage preventing groove portion 7 is formed by continuously or at predetermined intervals with a pressing portion composed of high pressure pressing and low pressure pressing so as to surround the liquid permeable region 20, and is mainly absorbed by the first absorber portion 4. This prevents leakage of excretions such as menstrual blood, and also prevents diffusion of excretion in the first absorber section 4.

［１．３］帯状部材及び補助吸収体
図５に示すように、帯状部材１０は、略縦長状に形成されると共に、伸長性材料を用いることにより、少なくとも一部が延伸可能に形成される。具体的には、帯状部材１０は、糸状に形成された複数の弾性材１２を一対の帯状の基材シート１１、１３で挟み込み、基材シート１１、１３のそれぞれを接着することにより形成される（図６（Ａ）参照）。さらに具体的には、帯状部材１０は、弾性材１２の長手方向（ＬＤ）に所定の張力をかけることにより、弾性材１２を所定の長さに延伸させ、延伸させた状態の弾性材１２を基材シート１１、１３で挟み、接着させることにより形成される。なお、帯状部材１０の他の伸張加工としては、部分的にスリット加工を施すことにより伸張可能としてもよく、波状のエンボス加工を施すことにより伸張可能としてもよい。 [1.3] Belt-shaped member and auxiliary absorber As shown in FIG. 5, the belt-shaped member 10 is formed in a substantially vertically long shape, and at least a part thereof is formed to be stretchable by using an extensible material. . Specifically, the belt-like member 10 is formed by sandwiching a plurality of elastic members 12 formed in a thread shape between a pair of belt-like base material sheets 11 and 13 and bonding the base material sheets 11 and 13 respectively. (See FIG. 6A). More specifically, the band-shaped member 10 extends the elastic material 12 to a predetermined length by applying a predetermined tension in the longitudinal direction (LD) of the elastic material 12, and the elastic material 12 in the stretched state is stretched. It is formed by sandwiching and adhering between the base material sheets 11 and 13. In addition, as another extending | stretching process of the strip | belt-shaped member 10, it is good also as extending | stretching by giving a slit process partially, and good also as extending | stretching by giving a wave-like embossing process.

帯状部材１０は、生理用ナプキン本体５の長手方向（ＬＤ）の一端側に設けられた接合部８において生理用ナプキン本体５と接合される。そして、帯状部材１０の他端側は、生理用ナプキン本体５と接合されない自由端１０ｒであり、自由端１０ｒには、補助吸収体６が連結される。 The band-like member 10 is joined to the sanitary napkin body 5 at a joint 8 provided on one end side in the longitudinal direction (LD) of the sanitary napkin body 5. And the other end side of the strip | belt-shaped member 10 is the free end 10r which is not joined with the sanitary napkin main body 5, and the auxiliary absorber 6 is connected with the free end 10r.

補助吸収体６は、第２吸収体部１００を一対の帯状の基材シート１１、１３で挟み込み、基材シート１１、１３のそれぞれと第２吸収体部１００とを接着することにより形成される。なお、本実施形態においては、補助吸収体６は、帯状部材１０を形成する基材シート１１、１３を用いて帯状部材１０と連続するように形成したが、本発明においてはこれに限らない。例えば、補助吸収体６は、帯状部材１０と別体に形成し、接合する構成であってもよい。また、帯状部材１０は、帯状部材１０を形成する基材シート１１、１３を用いて補助吸収体６を構成した場合においても、補助吸収体６と生理用ナプキン本体５とを連結させたというものとする。 The auxiliary absorbent body 6 is formed by sandwiching the second absorbent body portion 100 between a pair of strip-like base material sheets 11 and 13 and bonding each of the base material sheets 11 and 13 and the second absorbent body portion 100. . In addition, in this embodiment, although the auxiliary absorber 6 was formed so that it might continue with the strip | belt-shaped member 10 using the base material sheets 11 and 13 which form the strip | belt-shaped member 10, in this invention, it is not restricted to this. For example, the auxiliary absorbent body 6 may be configured to be formed separately from the belt-shaped member 10 and bonded. Further, the band-shaped member 10 is obtained by connecting the auxiliary absorbent body 6 and the sanitary napkin main body 5 even when the auxiliary absorbent body 6 is configured using the base sheet 11 or 13 forming the band-shaped member 10. And

また、補助吸収体６の帯状部材１０と連結する側と反対側の端部には、把持部６２が設けられている。把持部６２は、生理用ナプキン本体５の長手方向（ＬＤ）における外縁から延出するように配置される。なお、把持部６２は、着用者が指等で摘める程度延出していればよい。 In addition, a gripping portion 62 is provided at the end of the auxiliary absorbent body 6 opposite to the side connected to the belt-like member 10. The gripping part 62 is arranged so as to extend from the outer edge in the longitudinal direction (LD) of the sanitary napkin body 5. In addition, the holding | gripping part 62 should just be extended to such an extent that a wearer can pick with a finger | toe etc.

このように、帯状部材１０の自由端１０ｒ側に第２吸収体部１００を有する補助吸収体６を設けることにより、補助吸収体６は、帯状部材１０の延伸時に生理用ナプキン本体５の外縁部からいずれの方向（第２位置）へも延出可能になる。言い換えると、補助吸収体６に設けられる第２吸収体部１００が帯状部材１０の延伸時に生理用ナプキン本体５の外縁部からいずれの方向（第２位置）へも延出可能になる。これにより、表面シート側からみた吸収体（第１吸収体部４及び第２吸収体部１００）の面積を広くすることができ、例えば、生理用ナプキン本体５から体液等の排泄物が漏れ出し、着用者の臀部を伝って流れ出そうな場合においても、生理用ナプキン本体５から補助吸収体６を排泄物が流れ出しそうないずれかの位置（例えば、臀部方向側）に延出させて装着しておくことにより、第２吸収体部１００で排泄物を吸収することが可能になる。 Thus, by providing the auxiliary absorbent body 6 having the second absorbent body portion 100 on the free end 10r side of the band-shaped member 10, the auxiliary absorbent body 6 can be used as the outer edge of the sanitary napkin body 5 when the band-shaped member 10 is stretched. Can extend in any direction (second position). In other words, the second absorbent body portion 100 provided in the auxiliary absorbent body 6 can extend from the outer edge portion of the sanitary napkin main body 5 in any direction (second position) when the strip member 10 is stretched. Thereby, the area of the absorber (the first absorber portion 4 and the second absorber portion 100) viewed from the top sheet side can be increased. For example, excrement such as body fluid leaks from the sanitary napkin body 5. Even when it seems to flow through the wearer's buttocks, the auxiliary absorbent body 6 is extended from the sanitary napkin main body 5 to any position where excrement is likely to flow (for example, the buttocks direction side) and worn. By doing so, excreta can be absorbed by the second absorber 100.

なお、補助吸収体６が配置される領域においては、第２吸収体部１００に対応する領域であって、帯状部材１０の非肌当接面側に液不透過性のシート（図示せず）を配置することが好ましい。この液不透過性のシートは、帯状部材１０の自由端１０ｒ側における外縁部を覆うように設けられることが好ましい。また、液不透過性のシートは、帯状部材１０の両側の少なくとも一部を覆うように設けられることが好ましい。これにより、吸収性部材で吸収した排泄物が係止される下着５０に染み出すことを防止することが可能になるためである。 In addition, in the area | region where the auxiliary absorber 6 is arrange | positioned, it is an area | region corresponding to the 2nd absorber part 100, Comprising: A liquid-impermeable sheet | seat (not shown) on the non-skin contact surface side of the strip | belt-shaped member 10 Is preferably arranged. This liquid-impermeable sheet is preferably provided so as to cover the outer edge of the belt-like member 10 on the free end 10r side. Further, the liquid-impermeable sheet is preferably provided so as to cover at least a part of both sides of the belt-like member 10. This is because it is possible to prevent the excrement absorbed by the absorbent member from leaking into the undergarment 50 that is locked.

［１．４］カバー部材
カバー部材１５は、生理用ナプキン本体５の両側部及び前方領域（Ｆ）における外縁部において生理用ナプキン本体５と接合される。すなわち、カバー部材１５は、後方領域（Ｒ）における長手方向端部が開口するような態様になる。 [1.4] Cover Member The cover member 15 is joined to the sanitary napkin body 5 at both sides of the sanitary napkin body 5 and the outer edge portion in the front region (F). That is, the cover member 15 is in such a mode that the end in the longitudinal direction in the rear region (R) is opened.

カバー部材１５の長手方向（ＬＤ）における長さは、例えば、生理用ナプキン本体５の長手方向（ＬＤ）の長さの１０〜１００％の範囲が好ましく、さらに好ましくは、５０〜９０％の範囲が例示できる。１０％より小さいと、例えば、生理用ナプキン本体５と帯状部材１０との自由度が大きすぎてしまい、着用中にずれる可能性があるためである。また、１００％より大きいと、例えば、帯状部材１０を延伸させて下着５０に係止させる際に邪魔になるおそれがあるためである。また、例えば、帯状部材１０を生理用ナプキン１の幅方向（ＷＤ）へ引き出して使用する場合に、長手方向（ＬＤ）における規制が生じ、カバー部材１５の端部で帯状部材１０が折れ曲がったり、捩れたりして使用し難くなるためである。 The length of the cover member 15 in the longitudinal direction (LD) is preferably in the range of 10 to 100%, more preferably in the range of 50 to 90% of the length of the sanitary napkin body 5 in the longitudinal direction (LD). Can be illustrated. If it is less than 10%, for example, the degree of freedom between the sanitary napkin body 5 and the band-like member 10 is too large, and there is a possibility that the sanitary napkin body 5 and the band-like member 10 may be shifted during wearing. Further, if it is larger than 100%, for example, there is a possibility that it may become an obstacle when the belt-like member 10 is stretched and locked to the underwear 50. Further, for example, when the band-shaped member 10 is used by being pulled out in the width direction (WD) of the sanitary napkin 1, restriction in the longitudinal direction (LD) occurs, and the band-shaped member 10 is bent at the end of the cover member 15, This is because it becomes difficult to use due to twisting.

カバー部材１５の幅方向（ＷＤ）における長さは、例えば、生理用ナプキン本体５の幅方向（ＷＤ）の長さの３０〜１５０％の範囲が好ましく、さらに好ましくは、５０〜１１０％の範囲が例示できる。３０％より小さいと、例えば、生理用ナプキン本体５を十分に身体へ密着させることができなくなるためである。また、１５０％より大きいと、例えば、大腿部と接触する面積が過剰となり、擦れ等による肌トラブルを発症させる可能性があるためである。 For example, the length of the cover member 15 in the width direction (WD) is preferably in the range of 30 to 150%, more preferably in the range of 50 to 110% of the length in the width direction (WD) of the sanitary napkin body 5. Can be illustrated. This is because, if it is smaller than 30%, for example, the sanitary napkin body 5 cannot be sufficiently adhered to the body. Further, if it is larger than 150%, for example, the area in contact with the thigh becomes excessive, which may cause skin troubles due to rubbing or the like.

また、カバー部材１５の幅方向（ＷＤ）における長さは、例えば、帯状部材１０の幅方向（ＷＤ）の長さの１００〜２００％の範囲が好ましく、さらに好ましくは、１０５〜１５０％の範囲が例示できる。１００％より小さいと、例えば、帯状部材１０を延伸させる際にスムーズに伸ばすことができないためである。また、例えば、帯状部材１０を生理用ナプキン１の幅方向（ＷＤ）へ引き出して使用する場合に、幅方向（ＷＤ）のおける遊び（自由度）が少なく（小さく）なるため、カバー部材１５の端部で帯状部材１０が折れ曲がったり、捩れたりして使用し難くなるためである。また、２００％より大きいと、例えば、帯状部材１０の幅方向（ＷＤ）における自由度が大きすぎるため生理用ナプキン本体５の中心軸と帯状部材１０の中心軸とがずれてしまうおそれがあるためである。 Further, the length of the cover member 15 in the width direction (WD) is, for example, preferably in the range of 100 to 200%, more preferably in the range of 105 to 150% of the length in the width direction (WD) of the strip member 10. Can be illustrated. This is because, if it is smaller than 100%, for example, when the belt-like member 10 is stretched, it cannot be smoothly stretched. Further, for example, when the band-shaped member 10 is used by being pulled out in the width direction (WD) of the sanitary napkin 1, the play (degree of freedom) in the width direction (WD) is less (smaller). This is because the belt-like member 10 is bent or twisted at the end, making it difficult to use. If it is larger than 200%, for example, the degree of freedom in the width direction (WD) of the band-shaped member 10 is too large, and the central axis of the sanitary napkin body 5 and the central axis of the band-shaped member 10 may be misaligned. It is.

カバー部材１５は、生理用ナプキン本体５の長手方向（ＬＤ）における全域を覆う必要はなく、少なくとも後方領域（Ｒ）における補助吸収体６の把持部６２近傍に配置されればよい。少なくとも帯状部材の後方領域（Ｒ）に配置されていると、帯状部材１０が必要以上に幅方向（ＷＤ）に摺動することを防止することができ、着用中に生理用ナプキン本体５と帯状部材１０とがずれてしまうことを防止することが可能になるためである。また、カバー部材１５は、１つに限らず複数設けてもよい。 The cover member 15 does not need to cover the entire region of the sanitary napkin body 5 in the longitudinal direction (LD), and may be disposed at least near the grip portion 62 of the auxiliary absorbent body 6 in the rear region (R). If it is arranged at least in the rear region (R) of the belt-like member, it can be prevented that the belt-like member 10 slides in the width direction (WD) more than necessary, and the sanitary napkin body 5 and the belt-like shape during wearing. This is because it is possible to prevent the member 10 from being displaced. Further, the number of cover members 15 is not limited to one, and a plurality of cover members 15 may be provided.

カバー部材１５は、表面シート部２を延長させこの延長部分を用いてもよく、裏面シート部３を延長させこの延長部分を用いるものであってもよい。表面シート部２又は裏面シート部３を延長して用いた場合、延長させて設けた各シートを非肌当接面側において重ねて接合することができる。例えば、生理用ナプキン本体５の非肌当接面側の幅方向（ＷＤ）における略中央部において、生理用ナプキン本体５の幅方向（ＷＤ）における長さの５０％以上を延長させ、それぞれの延長したシート同士を折り返し、積層した状態で接合してもよい。 The cover member 15 may extend the top sheet portion 2 and use this extended portion, or may extend the back surface sheet portion 3 and use this extended portion. When the top sheet portion 2 or the back sheet portion 3 is extended and used, the extended sheets can be overlapped and joined on the non-skin contact surface side. For example, in the substantially central portion in the width direction (WD) of the sanitary napkin body 5 on the non-skin contact surface side, 50% or more of the length in the width direction (WD) of the sanitary napkin body 5 is extended, The extended sheets may be folded back and joined in a stacked state.

カバー部材１５は、両側部で折り返して生理用ナプキン本体５と接合させる場合においては、その折返し部に長手方向（ＬＤ）に伸びる弾性材を配置することが好ましい。カバー部材１５の両側部に長手方向（ＬＤ）に伸びる弾性材を配置した場合には、例えば、生理用ナプキン本体５又はカバー部材１５の幅方向（ＷＤ）にこれらを捩れさせるような力が働いた場合においても、弾性材の復元力によりその力を抑制させることが可能になるためである。 When the cover member 15 is folded at both side portions and joined to the sanitary napkin main body 5, it is preferable to arrange an elastic material extending in the longitudinal direction (LD) at the folded portion. When elastic materials extending in the longitudinal direction (LD) are disposed on both sides of the cover member 15, for example, a force that twists them in the width direction (WD) of the sanitary napkin body 5 or the cover member 15 works. This is because the force can be suppressed by the restoring force of the elastic material.

カバー部材１５は、生理用ナプキン１の幅方向（ＷＤ）に伸縮可能に形成してもよい。幅方向（ＷＤ）に伸縮可能に形成することより帯状部材１０をカバー部材１５内で保持可能となるためである。また、例えば、帯状部材１０を生理用ナプキン１の幅方向（ＷＤ）へ引き出して使用する場合に、カバー部材１５が生理用ナプキン１の幅方向（ＷＤ）及び厚さ方向（ＴＤ）に伸長する伸縮することが可能となり、帯状部材１０を引き出しやすくなるためである。また、例えば、下着が弛んだり、身体の動きに伴って変形することにより下着と身体に相対的なずれが生じた場合においても、カバー部材１５がそのずれに追従して延伸又は伸縮するため、身体と生理用ナプキン本体５とを密着させた状態を保持することが可能になる。なお、カバー部材１５は、カバー部材１５の全部を伸縮可能に形成してもよく、その一部を伸縮可能に形成してもよい。例えば、後方領域（Ｒ）におけるカバー部材１５の開口部分の近傍を伸縮可能に形成してもよい。 The cover member 15 may be formed to be stretchable in the width direction (WD) of the sanitary napkin 1. This is because the band-shaped member 10 can be held in the cover member 15 by being formed to be extendable and contractible in the width direction (WD). For example, when the band-shaped member 10 is used by being pulled out in the width direction (WD) of the sanitary napkin 1, the cover member 15 extends in the width direction (WD) and the thickness direction (TD) of the sanitary napkin 1. This is because it is possible to expand and contract and to easily pull out the belt-like member 10. In addition, for example, even when the underwear loosens or deforms with the movement of the body, a relative shift between the underwear and the body occurs, the cover member 15 extends or contracts following the shift, It is possible to maintain a state in which the body and the sanitary napkin body 5 are in close contact with each other. Note that the cover member 15 may be formed so that the entire cover member 15 can be expanded or contracted, or a part of the cover member 15 can be expanded and contracted. For example, the vicinity of the opening portion of the cover member 15 in the rear region (R) may be formed to be extendable.

［１．５］剥離シート及び固定部
カバー部材１５には、剥離シート２００が接合される。具体的には、剥離シート２００は、カバー部材１５の後方領域（Ｒ）に設けられる固定部２０１において、係止部９ｒの全部を覆うように配置されるとともに、カバー部材１５に接合される。なお、剥離シート２００のカバー部材１５への接合方法としては、ホットメルト接着剤により接合してもよく、エンボス加工又はソニック加工により接合してもよい。このように、係止部９ｒを剥離シート２００で覆うことにより、係止部９ｒをカバー部材１５で被包することが可能となると共に、例えば、係止部９ｒに粘着材を塗布した場合においても、使用者の意志とは異なる場所に係止部９ｒが貼り付くことを防止することが可能になる。また、剥離シート２００とカバー部材１５とを固定部２０１で接合させることにより、帯状部材１０の延伸と連動させて係止部９ｒから剥離シート２００を剥がすことが可能となり、容易に係止部９ｒを下着５０に係止させることが可能になる。 [1.5] Release Sheet and Fixing Section The release sheet 200 is joined to the cover member 15. Specifically, the release sheet 200 is disposed so as to cover the entire locking portion 9 r in the fixing portion 201 provided in the rear region (R) of the cover member 15 and is joined to the cover member 15. In addition, as a joining method to the cover member 15 of the peeling sheet 200, you may join by a hot-melt-adhesive, and may join by embossing or sonic processing. Thus, by covering the locking portion 9r with the release sheet 200, the locking portion 9r can be encapsulated with the cover member 15, and for example, when an adhesive material is applied to the locking portion 9r. However, it is possible to prevent the locking portion 9r from sticking to a place different from the user's will. Further, by joining the release sheet 200 and the cover member 15 at the fixing portion 201, the release sheet 200 can be peeled from the locking portion 9r in conjunction with the extension of the belt-like member 10, and the locking portion 9r can be easily removed. Can be locked to the underwear 50.

［１．６］固定部と係止部との位置関係
固定部２０１が設けられる位置としては、図７（Ａ）及び（Ｂ）に示すように、カバー部材１５の後方領域（Ｒ）側の端部２１０と係止部９ｒの後方領域（Ｒ）側の端部２１１との間であることが好ましい。言い換えると、図７（Ｂ）に示すように、固定部２０１は、係止部９ｒの後方領域（Ｒ）側の端部２１１よりも後方領域（Ｒ）側のカバー部材１５に設けられる。具体的には、固定部２０１の後方領域（Ｒ）側の端部２１２は、係止部９ｒの後方領域（Ｒ）側の端部２１１と同じ位置又は係止部９ｒの後方領域（Ｒ）側の端部２１１よりも１ｍｍ以上後方領域（Ｒ）側に配置される。好ましくは、係止部９ｒの後方領域（Ｒ）側の端部２１１よりも１〜５０ｍｍの範囲において後方領域（Ｒ）側に配置される。さらに好ましくは、係止部９ｒの後方領域（Ｒ）側の端部２１１よりも５〜２０ｍｍの範囲において後方領域（Ｒ）側に配置される。 [1.6] Positional relationship between the fixing part and the locking part As shown in FIGS. 7A and 7B, the position where the fixing part 201 is provided is on the rear region (R) side of the cover member 15. It is preferably between the end portion 210 and the end portion 211 on the rear region (R) side of the locking portion 9r. In other words, as shown in FIG. 7B, the fixing portion 201 is provided on the cover member 15 on the rear region (R) side with respect to the end portion 211 on the rear region (R) side of the locking portion 9r. Specifically, the end 212 on the rear region (R) side of the fixing portion 201 is the same position as the end 211 on the rear region (R) side of the locking portion 9r or the rear region (R) of the locking portion 9r. It is arranged on the rear region (R) side by 1 mm or more from the side end 211. Preferably, it is arranged on the rear region (R) side in the range of 1 to 50 mm from the end portion 211 on the rear region (R) side of the locking portion 9r. More preferably, it is disposed on the rear region (R) side within a range of 5 to 20 mm from the end portion 211 on the rear region (R) side of the locking portion 9r.

このように、固定部２０１を係止部９ｒの後方領域（Ｒ）側の端部２１１よりも後方領域（Ｒ）側に設けることにより、例えば、図７（Ａ）に示すように、帯状部材１０を延伸させた場合において、剥離シート２００が固定部２０１を起点として係止部９ｒから剥がれ係止部９ｒを露出することとなるため、容易に帯状部材１０を下着５０に貼り付けることが可能になる。 Thus, by providing the fixing portion 201 on the rear region (R) side of the end portion 211 on the rear region (R) side of the locking portion 9r, for example, as shown in FIG. 10 is stretched, the release sheet 200 is peeled off from the locking portion 9r with the fixing portion 201 as a starting point to expose the locking portion 9r. Therefore, the belt-like member 10 can be easily attached to the undergarment 50. become.

［１．７］生理用ナプキン本体と帯状部材との接合位置
生理用ナプキン本体５と帯状部材１０とは、接合部８において接合される。生理用ナプキン本体５に対する帯状部材１０の接合位置としては、生理用ナプキン１の装着時において、着用者の膣口よりも前方領域（Ｆ）であることが好ましい。例えば、図８（Ａ）に示すように、着用者の排泄部近傍にある隆起部に設けられることが好ましい。具体的には、膣口の近傍にある恥骨に該当する位置であることが好ましい。恥骨に該当する位置は、例えば、その周辺箇所よりも硬く、若干隆起しているため、下着５０からの圧力が高くなり、生理用ナプキン本体５が身体からずれにくくなるためである。これにより、例えば、装着時に帯状部材１０を引っ張って、延伸させた場合においてもその応力により生理用ナプキン本体５が屈曲することがなく、装着時及び着用中に生理用ナプキン本体５のずれが生じにくくなる。 [1.7] Joining position of sanitary napkin main body and belt-like member The sanitary napkin main body 5 and the belt-like member 10 are joined at the joint 8. The joining position of the band-shaped member 10 to the sanitary napkin body 5 is preferably the front region (F) from the wearer's vaginal opening when the sanitary napkin 1 is worn. For example, as shown to FIG. 8 (A), it is preferable to provide in the protruding part in the wearer's excretion part vicinity. Specifically, the position corresponding to the pubic bone in the vicinity of the vaginal opening is preferable. This is because, for example, the position corresponding to the pubic bone is harder than the surrounding portion and slightly raised, so that the pressure from the underwear 50 is increased and the sanitary napkin body 5 is less likely to be displaced from the body. Thus, for example, even when the belt-like member 10 is pulled and stretched at the time of wearing, the sanitary napkin body 5 is not bent by the stress, and the sanitary napkin body 5 is displaced during wearing and during wearing. It becomes difficult.

また、接合部８は、各基材シート１１、１３の間に所定の強度を備えるシート部材１４を挟持させてもよい。これにより、接合部８が所定の強度を有するため、帯状部材１０の接合を安定させることができる。 Further, the joint portion 8 may sandwich the sheet member 14 having a predetermined strength between the base sheet 11 and 13. Thereby, since the junction part 8 has predetermined intensity | strength, joining of the strip | belt-shaped member 10 can be stabilized.

［１．８］下着との係止位置
生理用ナプキン１は、長手方向（ＬＤ）における両端に、下着５０等と係止する係止部９ｆ、９ｒを備える。係止部９ｆは、前方領域（Ｆ）において下着５０等と係止し、係止部９ｒは、後方領域（Ｒ）において下着５０等と係止する。ここで、係止部９ｆは、例えば、生理用ナプキン本体５と帯状部材１０とが接合される接合部８と対向する位置（例えば、カバー部材１５における当該位置）に設けられることが好ましい。生理用ナプキン本体５と帯状部材１０との接合部８においては、帯状部材１０の自由端１０ｒに対する起点であり、帯状部材１０の張力が生理用ナプキン本体５側へ最も加わる箇所となり、当該箇所においては生理用ナプキン本体５が下着５０とずれにくくなるためである。 [1.8] Locking position with underwear The sanitary napkin 1 includes locking portions 9f and 9r that lock the underwear 50 and the like at both ends in the longitudinal direction (LD). The locking portion 9f is locked with the underwear 50 or the like in the front region (F), and the locking portion 9r is locked with the underwear 50 or the like in the rear region (R). Here, the locking portion 9f is preferably provided, for example, at a position facing the joining portion 8 where the sanitary napkin body 5 and the belt-like member 10 are joined (for example, the position in the cover member 15). The joint 8 between the sanitary napkin main body 5 and the band-shaped member 10 is a starting point with respect to the free end 10r of the band-shaped member 10, and is the place where the tension of the band-shaped member 10 is most applied to the sanitary napkin main body 5 side. This is because the sanitary napkin main body 5 is not easily displaced from the underwear 50.

また、係止部９ｒは、例えば、帯状部材１０の後方領域（Ｒ）側における最後端よりも前方領域（Ｆ）側にあることが好ましい。身体は、膣口から後方に向かって大きく湾曲していることが多いため、後方領域（Ｒ）側にあることによって、帯状部材１０の伸縮範囲が拡大するためである。また、身体の湾曲に沿って帯状部材１０が伸長することで、帯状部材１０による応力が排泄部近傍に位置する生理用ナプキン本体５へ伝わり易くなるためである。さらに、帯状部材１０の後方領域（Ｒ）側における最後端よりも若干前方領域（Ｆ）側に設けることにより、着用者が把持部６２を把持するときに指等に係止部９ｒの係止材が付くことを防止できるためである。 Moreover, it is preferable that the latching | locking part 9r exists in the front area | region (F) side rather than the rearmost end in the back area | region (R) side of the strip | belt-shaped member 10, for example. This is because the body is often greatly curved rearward from the vaginal opening, and the expansion / contraction range of the band-shaped member 10 is expanded by being on the rear region (R) side. Moreover, it is because the strip | belt-shaped member 10 expand | extends along the curve of a body, and the stress by the strip | belt-shaped member 10 becomes easy to be transmitted to the sanitary napkin main body 5 located in the excretion part vicinity. Further, by providing the belt-like member 10 on the front region (F) side slightly from the rearmost end on the rear region (R) side, when the wearer grips the grip portion 62, the lock portion 9r is locked to the finger or the like. This is because the material can be prevented from attaching.

なお、着用中に帯状部材１０が下着等から外れないようにするためには、伸縮性を有する帯状部材１０の場合、帯状部材１０の収縮力より係止材による係止力の方が大きい必要がある。よって、係止力つまりせん断応力は、５〜５００ｃＮ／２５ｍｍの範囲である収縮力より大きくなるように設定することが好ましい。 In order to prevent the belt-like member 10 from being detached from the underwear or the like during wearing, in the case of the belt-like member 10 having stretchability, the locking force by the locking material needs to be larger than the contraction force of the belt-like member 10. There is. Therefore, it is preferable to set the locking force, that is, the shear stress, to be larger than the contraction force in the range of 5 to 500 cN / 25 mm.

［１．９］作用及び効果
図８（Ａ）から図９（Ｂ）により、本発明の第１実施形態における生理用ナプキン１の作用及び効果について説明する。 [1.9] Action and Effect The action and effect of the sanitary napkin 1 according to the first embodiment of the present invention will be described with reference to FIGS. 8A to 9B.

まず、着用者は、生理用ナプキン１を下着５０の所定の位置に配置し、生理用ナプキン１の非肌当接面側における前方領域（Ｆ）側の係止部９ｆを下着５０に係止させる。なお、下着５０の所定の位置とは、例えば、生理用ナプキン１における液透過領域２０を着用者の排泄部に当接可能な予測位置を含む。 First, the wearer places the sanitary napkin 1 at a predetermined position of the underwear 50, and locks the front region (F) side locking portion 9 f on the non-skin contact surface side of the sanitary napkin 1 to the underwear 50. Let The predetermined position of the underwear 50 includes, for example, a predicted position where the liquid permeable region 20 in the sanitary napkin 1 can be brought into contact with the excretion part of the wearer.

そして、生理用ナプキン１の前方領域（Ｆ）の係止部９ｆにおける下着５０と生理用ナプキン１とを押さえたまま、帯状部材１０の自由端１０ｒ側に設けられた補助吸収体６の把持部６２を把持し、帯状部材１０を長手方向（ＬＤ）における後方領域（Ｒ）側に引っ張る。このとき、補助吸収体６（第２吸収体部１００）は、帯状部材１０の自由端１０ｒ側に配置されることとなるので、長手方向（ＬＤ）以外の方向（例えば、幅方向（ＷＤ）や長手方向（ＬＤ）交差する方向）にも移動可能となる。 And the holding part of the auxiliary | assistant absorber 6 provided in the free end 10r side of the strip | belt-shaped member 10, holding down the underwear 50 and the sanitary napkin 1 in the latching | locking part 9f of the front area | region (F) of the sanitary napkin 1 62 is gripped, and the belt-like member 10 is pulled toward the rear region (R) in the longitudinal direction (LD). At this time, since the auxiliary absorbent body 6 (second absorbent body portion 100) is disposed on the free end 10r side of the band-shaped member 10, a direction other than the longitudinal direction (LD) (for example, the width direction (WD)). Or the longitudinal direction (LD) crossing direction).

そして、帯状部材１０が延伸されると、第２吸収体部１００は、帯状部材１０により生理用ナプキン本体５と連結された状態で、第２吸収体部１００が生理用ナプキン本体５の外縁から延出しない態様（第１位置）から、生理用ナプキン本体５の外縁から延出する態様（第２位置）に移動可能となる。 When the belt-like member 10 is stretched, the second absorbent body portion 100 is connected to the sanitary napkin main body 5 by the belt-like member 10, and the second absorbent body portion 100 is separated from the outer edge of the sanitary napkin main body 5. It is possible to move from an aspect that does not extend (first position) to an aspect that extends from the outer edge of the sanitary napkin body 5 (second position).

さらに、帯状部材１０が延伸されると、帯状部材１０の非肌当接面側に配置された係止部９ｒが外部に露出される。このとき係止部９ｒを被覆する剥離シート２００は、図７（Ｂ）に示すように、カバー部材１５と接合されているため、帯状部材１０が引っ張られて、係止部９ｒが外部に移動されることにより固定部２０１を起点にして係止部９ｒから剥離される（図７（Ａ）参照）。このようにして外部に露出された係止部９ｒを下着５０の所定の位置に貼り付ける。なお、所定の位置とは、着用者の排泄部に当接するように配置される第１吸収体部４の近傍を含み、例えば、臀部側における排泄部近傍を含む。また、係止部９ｒは、帯状部材１０をできるだけ延伸させた状態で、下着５０に貼り付けることが好ましい。 Further, when the belt-like member 10 is extended, the engaging portion 9r disposed on the non-skin contact surface side of the belt-like member 10 is exposed to the outside. At this time, as shown in FIG. 7B, the release sheet 200 covering the locking portion 9r is joined to the cover member 15, so that the belt-like member 10 is pulled and the locking portion 9r moves to the outside. As a result, the fixing part 201 is peeled off from the locking part 9r (see FIG. 7A). In this way, the engaging portion 9r exposed to the outside is attached to a predetermined position of the underwear 50. In addition, the predetermined position includes the vicinity of the first absorbent body portion 4 disposed so as to contact the wearer's excretion portion, and includes, for example, the vicinity of the excretion portion on the buttock side. Moreover, it is preferable that the latching | locking part 9r is affixed on the underwear 50 in the state which extended the strip | belt-shaped member 10 as much as possible.

生理用ナプキン１の装着完了後、この状態で下着５０を着用することにより、帯状部材１０と生理用ナプキン本体５がなだらかな湾曲形状に変形し、帯状部材１０から生理用ナプキン本体５へ着用者の身体方向へ応力を伝える。そして、帯状部材１０は、生理用ナプキン本体５を吊り上げるように、身体側へと押し上げる。これにより、着用者の排泄部や排泄部付近の溝と生理用ナプキン１とを密着させることが可能になる（図８（Ａ）から（Ｃ）参照）。 After wearing the sanitary napkin 1, by wearing the underwear 50 in this state, the band-shaped member 10 and the sanitary napkin main body 5 are deformed into a gently curved shape, and the wearer moves from the band-shaped member 10 to the sanitary napkin main body 5. Transmit stress to the body direction. And the strip | belt-shaped member 10 pushes up to the body side so that the sanitary napkin main body 5 may be lifted. Thereby, a wearer's excretion part and the groove | channel of the excretion part vicinity, and the sanitary napkin 1 can be closely_contact | adhered (refer FIG. 8 (A) to (C)).

また、生理用ナプキン１は、第１吸収体部４を有する生理用ナプキン本体５とは別に、第２吸収体部１００を有する補助吸収体６を設け、補助吸収体６を生理用ナプキン本体５からいずれの方向へも延伸可能に配置しているため、着用者の体調に基づき補助吸収体６を引っ張り出して使用することが可能になる。そして、補助吸収体６を引っ張り出し、下着に貼り付けて使用することにより肌当接面側に表れる表面シート側から見た第１及び第２吸収体部４、１００の総表面積を調節することが可能になる。つまり、第１吸収体部４と第２吸収体部１００のそれぞれを肌当接面側に表れる吸収体として使用することが可能となるため、吸収体の総表面積を大きくすることができる。これにより、より多くの排泄物を吸収させることが可能になる。 Further, the sanitary napkin 1 is provided with an auxiliary absorbent body 6 having a second absorbent body portion 100 separately from the sanitary napkin main body 5 having the first absorbent body portion 4, and the auxiliary absorbent body 6 is provided with the sanitary napkin main body 5. Therefore, the auxiliary absorbent body 6 can be pulled out and used based on the physical condition of the wearer. Then, the total surface area of the first and second absorbent body parts 4 and 100 as seen from the surface sheet side appearing on the skin contact surface side is adjusted by pulling out the auxiliary absorbent body 6 and attaching it to the underwear. Is possible. That is, since it becomes possible to use each of the 1st absorber part 4 and the 2nd absorber part 100 as an absorber which appears on the skin contact surface side, the total surface area of an absorber can be enlarged. Thereby, it becomes possible to absorb more excrement.

また、図９（Ａ）及び（Ｂ）に示すように、帯状部材１０は、接合部８のみでの接合であり、補助吸収体６は、帯状部材１０の自由端１０ｒ側に配置されるため、例えば、図９（Ｂ）に示すように、生理用ナプキン本体５の長手方向（ＬＤ）以外の方向（例えば、幅方向（ＷＤ）や生理用ナプキン本体５の長手方向（ＬＤ）と交差する方向）にも引っ張ることが可能になる。同様に、下着５０に接合した後においても帯状部材１０の伸張部が剛性の低い材料で形成されているため、例えば、着用者が歩行等することにより、臀部が動き、生理用ナプキン１を装着する下着５０が生理用ナプキン１の幅方向（ＷＤ）に動いた場合においても、その動きに容易に追従することが可能になる。 Further, as shown in FIGS. 9A and 9B, the band-shaped member 10 is bonded only at the bonding portion 8, and the auxiliary absorbent body 6 is disposed on the free end 10 r side of the band-shaped member 10. For example, as shown in FIG. 9 (B), the cross direction intersects with a direction other than the longitudinal direction (LD) of the sanitary napkin body 5 (for example, the width direction (WD) and the longitudinal direction (LD) of the sanitary napkin body 5). Direction). Similarly, since the stretched portion of the belt-like member 10 is formed of a material having low rigidity even after being joined to the undergarment 50, for example, when the wearer walks, the buttocks move and the sanitary napkin 1 is attached. Even when the underwear 50 is moved in the width direction (WD) of the sanitary napkin 1, it is possible to easily follow the movement.

また、補助吸収体６と生理用ナプキン本体５とを連結する帯状部材１０を剛性の低い材料で形成するため、着用者に違和感を与えることなく着用者の動作に追従させることが可能となる。 Moreover, since the strip | belt-shaped member 10 which connects the auxiliary | assistant absorber 6 and the sanitary napkin main body 5 is formed with a material with low rigidity, it becomes possible to follow a wearer's operation | movement, without giving a wearer an uncomfortable feeling.

また、帯状部材１０が伸縮性を有することによって、例えば、下着が弛んだり、身体の動きに伴って変形することにより下着と身体に相対的なずれを生じさせても、帯状部材１０がそのずれに追従して伸縮するため、身体と生理用ナプキン１とを密着させた状態を保持することが可能になる。したがって、着用者の排泄部等と生理用ナプキン１との密着性を向上させ、経血等の排泄物の漏れを防止することが可能になる。 In addition, since the belt-like member 10 has elasticity, for example, even if the underwear is loosened or deformed with the movement of the body, the belt-like member 10 is not displaced. Therefore, the body and the sanitary napkin 1 can be kept in close contact with each other. Therefore, it becomes possible to improve the adhesion between the excretion part of the wearer and the sanitary napkin 1 and to prevent leakage of excrement such as menstrual blood.

［１．１０］その他
なお、本実施形態においては、帯状部材１０は、前方領域（Ｆ）に設けられた接合部８において生理用ナプキン本体５と接合され、補助吸収体６が生理用ナプキン本体５の後方領域（Ｒ）側のいずれかに延出する構成としたが、本発明においてはこれに限らない。例えば、帯状部材１０の両端に補助吸収体６を設けると共に、生理用ナプキン本体５の略中央部において、生理用ナプキン本体５と帯状部材１０とを接合させることにより、補助吸収体が前方領域（Ｆ）及び後方領域（Ｒ）のそれぞれの方向に延出可能と成るように構成してもよい。このように、補助吸収体を前方及び後方領域に延出可能に形成することにより、例えば、肌当接面側における吸収体部の表面積をより大きくすることが可能になる。 [1.10] Others In addition, in this embodiment, the strip | belt-shaped member 10 is joined with the sanitary napkin main body 5 in the junction part 8 provided in the front area | region (F), and the auxiliary absorber 6 is the sanitary napkin main body. However, the present invention is not limited to this. For example, the auxiliary absorbent body 6 is provided at both ends of the band-shaped member 10, and the sanitary napkin body 5 and the band-shaped member 10 are joined to each other in the front region (at a substantially central portion of the sanitary napkin body 5. You may comprise so that it can extend in each direction of F) and back area | region (R). In this way, by forming the auxiliary absorbent body so as to extend to the front and rear regions, for example, the surface area of the absorbent body portion on the skin contact surface side can be increased.

また、本実施形態においては、長手方向（ＬＤ）に伸びる１本の帯状部材１０を用いたが本発明においてはこれに限らない。例えば、それぞれが長手方向（ＬＤ）に平行に伸びるように配置される２本の帯状部材を用いて構成してもよい。このように、平行に伸びる２本の帯状部材を用いることにより、例えば、臀部のように左右の動きの異なる部位に好適に使用することができる。 Further, in the present embodiment, one strip member 10 extending in the longitudinal direction (LD) is used, but the present invention is not limited to this. For example, you may comprise using two strip | belt-shaped members each arrange | positioned so that it may extend in parallel with a longitudinal direction (LD). Thus, by using two strip-shaped members extending in parallel, for example, it can be suitably used for a part with different left and right movements such as a buttock.

［２．１］第２実施形態
図１０及び図１１を用いて、本発明の第２実施形態における生理用ナプキン１Ｂを説明する。 [2.1] Second Embodiment A sanitary napkin 1B according to a second embodiment of the present invention will be described with reference to FIGS.

なお、以下の実施形態において、特に説明しない部分は、第１実施形態と同様であり、図面に付した番号も第１実施形態と同様である場合は、同じ番号を付している。 In the following embodiments, parts that are not particularly described are the same as those in the first embodiment, and the same reference numerals are given to the numbers given in the drawings if they are the same as those in the first embodiment.

図１０及び図１１に示すように、第２実施形態に係る生理用ナプキン１Ｂは、帯状部材１０Ｂに折返し延伸部２１を設けたことにおいて第１実施形態と異なる。つまり、生理用ナプキン１Ｂは、帯状部材１０Ｂに折返し延伸部２１を設けることにより帯状部材１０Ｂを延伸可能とする。 As shown in FIGS. 10 and 11, the sanitary napkin 1 B according to the second embodiment differs from the first embodiment in that a folded extending portion 21 is provided on the belt-like member 10 B. In other words, the sanitary napkin 1B enables the band-shaped member 10B to be stretched by providing the folded-back extending portion 21 on the band-shaped member 10B.

このように、帯状部材１０Ｂは、所定量を長手方向（ＬＤ）に折り返して形成される折り返し延伸部２１を設けることにより、例えば、所定の延伸量を備えると共に、帯状部材１０Ｂをコンパクトに収納させることが可能になる。 As described above, the band-shaped member 10B is provided with the folded extending portion 21 formed by folding a predetermined amount in the longitudinal direction (LD), for example, to have a predetermined extending amount and to store the band-shaped member 10B in a compact manner. It becomes possible.

ここで、所定の延伸量とは、例えば、生理用ナプキン本体５の長手方向（ＬＤ）における長さの３０〜３００％の範囲が好ましく、さらに好ましくは、７０〜１５０％の範囲が例示できる。また、折返し延伸部２１における所定量とは、上記帯状部材１０Ｂの所定の延伸量を維持し得るために折り返し可能な長さを含む。 Here, the predetermined stretching amount is, for example, preferably in the range of 30 to 300% of the length in the longitudinal direction (LD) of the sanitary napkin body 5 and more preferably in the range of 70 to 150%. Further, the predetermined amount in the folded extending portion 21 includes a length that can be folded back in order to maintain the predetermined extending amount of the band-shaped member 10B.

また帯状部材１０Ｂは、折返し延伸部２１を設けて延伸可能とすることにより、例えば、非伸縮性シートを用いることが可能になる。ここで、非伸縮性シートとしては、例えば、不織布、フィルムシート等が例示できるが、帯状部材１０Ｂを吊り上げる際に加わる応力に耐え得る強度を有する部材であればよい。また、形状は、帯状、紐状等が例示できるが、帯状であることが好ましい。 In addition, the belt-like member 10B can be made of a non-stretchable sheet, for example, by providing the folded extending portion 21 so as to be stretchable. Here, examples of the non-stretchable sheet include a non-woven fabric and a film sheet. However, any non-stretchable sheet may be used as long as it has a strength capable of withstanding the stress applied when the belt-shaped member 10B is lifted. Moreover, although the shape can illustrate a strip shape, a string shape, etc., it is preferable that it is a strip shape.

［２．２］第３実施形態
図１２及び図１３を用いて、本発明の第３実施形態における生理用ナプキン１Ｃを説明する。 [2.2] Third Embodiment A sanitary napkin 1C according to a third embodiment of the present invention will be described with reference to FIGS.

図１２に示すように、第３実施形態に係る生理用ナプキン１Ｃは、第１吸収体部４を備える生理用ナプキン本体５Ｃと第２吸収体部１００Ｃを有する補助吸収体６Ｃとを、長手方向（ＬＤ）における端部同士で連結させると共に、それぞれを連結する連結部（帯状部材）２２を非肌当接面側に折り返し、生理用ナプキン本体５Ｃと補助吸収体６Ｃとが積層されるように配置することにおいて、第１実施形態と異なる。 As shown in FIG. 12, a sanitary napkin 1 C according to the third embodiment includes a sanitary napkin main body 5 C having a first absorbent body portion 4 and an auxiliary absorbent body 6 C having a second absorbent body portion 100 C in the longitudinal direction. The end portions in (LD) are connected to each other, and the connecting portions (band-like members) 22 that connect the respective ends are folded back to the non-skin contact surface side so that the sanitary napkin body 5C and the auxiliary absorbent body 6C are laminated. Arranging is different from the first embodiment.

連結部２２は、生理用ナプキン本体５Ｃの表面シート部２と裏面シート部３とを長手方向（ＬＤ）にそれぞれ延出させ、これらを貼り合わせることにより形成される。補助吸収体６Ｃは、この延出した表面シート部２及び裏面シート部３の端部において、表面シート部２及び裏面シート部３の間に第２吸収体部１００Ｃを挟持させて形成される。なお、補助吸収体６Ｃは、生理用ナプキン本体５Ｃの非肌当接面側に配置される。 The connecting portion 22 is formed by extending the top sheet portion 2 and the back sheet portion 3 of the sanitary napkin body 5C in the longitudinal direction (LD) and bonding them together. The auxiliary absorbent body 6 C is formed by sandwiching the second absorbent body part 100 C between the top sheet part 2 and the back sheet part 3 at the ends of the extended top sheet part 2 and back sheet part 3. The auxiliary absorbent body 6C is disposed on the non-skin contact surface side of the sanitary napkin body 5C.

ここで、連結部２２は、剛性の低い表面シート部２及び裏面シート部３により形成されるため、長手方向（ＬＤ）、幅方向（ＷＤ）及び厚さ方向（ＴＤ）における自由度が高くなる。これにより、例えば、長手方向（ＬＤ）及び幅方向（ＷＤ）のそれぞれにおいて、連結部２２の一部が折れ起点となり、補助吸収体６Ｃは、この折れ起点と直交する方向に生理用ナプキン本体５Ｃの外縁から延出可能となる。 Here, since the connecting portion 22 is formed by the top sheet portion 2 and the back sheet portion 3 having low rigidity, the degree of freedom in the longitudinal direction (LD), the width direction (WD), and the thickness direction (TD) increases. . Thereby, for example, in each of the longitudinal direction (LD) and the width direction (WD), a part of the connecting portion 22 becomes a folding start point, and the auxiliary absorbent body 6C has a sanitary napkin body 5C in a direction orthogonal to the folding starting point. It is possible to extend from the outer edge.

このように、生理用ナプキン本体５Ｃの外縁から補助吸収体６Ｃ（第２吸収体部１００Ｃ）を延出可能にすることにより、肌当接面側における吸収面積を調節することが可能になる。つまり、補助吸収体６Ｃにおける第２吸収体部１００Ｃを延出させた場合においては、肌当接面側の吸収面積を大きくすることができ、延出させない場合においては、通常の大きさを保つことが可能になる。 Thus, by making it possible to extend the auxiliary absorbent body 6C (second absorbent body portion 100C) from the outer edge of the sanitary napkin main body 5C, it is possible to adjust the absorption area on the skin contact surface side. That is, when the second absorbent body portion 100C of the auxiliary absorbent body 6C is extended, the absorption area on the skin contact surface side can be increased, and when it is not extended, the normal size is maintained. It becomes possible.

これにより、着用者はその日の体調（状態）により肌当接面側における吸収体部の吸収面積を調節して使用することが可能になる。 Thereby, a wearer can adjust and use the absorption area of the absorber part in the skin contact surface side by the physical condition (state) of the day.

また、補助吸収体６Ｃは、剛性の低い表面シート部２及び裏面シート部３により形成される連結部２２により生理用ナプキン本体５Ｃと連結されるため、幅方向（ＷＤ）における自由度が高くなる。つまり、幅方向（ＷＤ）に摺動可能になる。これにより、例えば、着用者の歩行等により、臀部等が左右方向に動いた場合においても、幅方向（ＷＤ）に摺動可能なため、このような動作に容易に追従することが可能になる。 Further, since the auxiliary absorbent body 6C is connected to the sanitary napkin body 5C by the connecting portion 22 formed by the top sheet portion 2 and the back sheet portion 3 having low rigidity, the degree of freedom in the width direction (WD) is increased. . That is, it becomes possible to slide in the width direction (WD). Thereby, for example, even when the buttocks or the like moves in the left-right direction due to the wearer's walking or the like, it is possible to easily follow such an operation because it can slide in the width direction (WD). .

また、例えば、図１３（Ａ）及び（Ｂ）に示すように、生理用ナプキン１Ｃ’は、所定の接合部２３で生理用ナプキン本体５Ｃ’と連結部２２とを接合させてもよい。このように、接合部２３で生理用ナプキン本体５Ｃ’と連結部２２とを接合させることにより、例えば、補助吸収体６Ｃ（第２吸収体部１００Ｃ）の最大延出量を調節することが可能となる。また、延出時に連結部２２の折曲部分を残すように接合しておくことにより、例えば、補助吸収体６Ｃを最大量延出させた後においても、幅方向（ＷＤ）における自由度を有する部分が残るため、幅方向（ＷＤ）への摺動が容易になる。 For example, as shown in FIGS. 13A and 13B, the sanitary napkin 1 C ′ may join the sanitary napkin main body 5 C ′ and the connecting portion 22 at a predetermined joint 23. Thus, by joining the sanitary napkin body 5C ′ and the connecting portion 22 at the joint portion 23, for example, the maximum extension amount of the auxiliary absorbent body 6C (second absorbent body portion 100C) can be adjusted. It becomes. Moreover, by joining so that the bending part of the connection part 22 may be left at the time of extension, for example, after extending the maximum amount of auxiliary absorber 6C, it has the freedom degree in a width direction (WD). Since the portion remains, sliding in the width direction (WD) is facilitated.
