　一態様に係る吸収性物品は、前後方向と、前記前後方向に直交する幅方向と、表面シート、裏面シート及び吸収コアを有する本体部と、前記裏面シートに配置され、前記着用物品に吸収性物品を固定する粘着部と、前記裏面シートに配置された後処理用のテープ部材と、を有する吸収性物品であって、前記テープ部材は、前記テープ部材の一端側に配置され、かつ前記裏面シートに固定された固定部と、前記テープ部材の他端側に配置され、前記裏面シートに剥離可能に配置された非固定部と、を有し、前記粘着部は、前記テープ部材の一端側から前記他端側に向かう第１方向と直交する第２方向において前記非固定部を挟んで配置される一対の第１粘着部を有する。 The absorbent article according to one aspect is disposed in the front-rear direction, the width direction orthogonal to the front-rear direction, the main body having the top sheet, the back sheet, and the absorbent core, and the back sheet, and the absorbent article is absorbent. It is an absorbent article which has an adhesion part which fixes an article, and a tape member for post-processing arranged on the above-mentioned back sheet, and the above-mentioned tape member is arranged at one end side of the above-mentioned tape member, and A fixing portion fixed to the sheet, and a non-fixing portion disposed on the other end side of the tape member and releasably disposed on the back surface sheet, wherein the adhesive portion is the one end side of the tape member And a pair of first adhesive portions disposed across the non-fixed portion in a second direction orthogonal to the first direction from the second to the other end side.
　非固定部は、一対の第１粘着部によって挟まれている。一対の第１粘着部が着用物品に固定された際に、第１粘着部間に領域は、着用物品と裏面シートによって挟まれた状態が維持され、露出しない。そのため、吸収性物品の着用時に、意図せずにテープ部材が折れたり剥がれたりする不具合を抑制できる。　 The non-fixed portion is sandwiched between the pair of first adhesive portions. When the pair of first adhesive parts is fixed to the wearing article, the region between the first adhesive parts is maintained in a state of being sandwiched between the wearing article and the back sheet, and is not exposed. Therefore, at the time of wear of the absorbent article, it is possible to suppress a defect that the tape member is broken or peeled unintentionally.
また、一対の第１粘着部は、着用時に着用物品に固定されている。そのため、吸収性物品が部分的にめくれた場合であっても、一対の第１粘着部及びその間の領域は、着用物品側に向かう状態が維持され、着用者の肌側に向かうように配置されない。一対の第１粘着部間の領域にテープ部材の非固定部が配置されているため、非固定部が肌によって擦れ難く、意図せずにテープ部材が折れたり剥がれたりする不具合を抑制できる。 Moreover, a pair of 1st adhesion parts are being fixed to a wearing article at the time of wear. Therefore, even when the absorbent article is partially curled up, the pair of first adhesive portions and the region between them are maintained toward the worn article and are not arranged toward the skin of the wearer . Since the non-fixed portion of the tape member is disposed in the region between the pair of first adhesive portions, the non-fixed portion is not easily rubbed by the skin, and it is possible to suppress a defect that the tape member is broken or peeled off unintentionally.
　好ましい一態様によれば、前記第１粘着部は、前記第１方向に延びており、前記第１粘着部と前記非固定部が前記第２方向において重なる重複領域を有し、前記重複領域の前記第１方向の長さは、前記非固定部の前記第１方向の全域に対する５０％以上である。 According to a preferred aspect, the first adhesive portion extends in the first direction, and has an overlapping region in which the first adhesive portion and the non-fixing portion overlap in the second direction; The length in the first direction is 50% or more of the entire area in the first direction of the non-fixed portion.
　このような構成によれば、非固定部の半分以上の領域において非固定部のめくれや剥がれを抑制でき、吸収性物品の着用時に意図せずにテープ部材が折れたり剥がれたりする不具合を効果的に抑制できる。 According to such a configuration, it is possible to suppress the turning off and peeling off of the non-fixed portion in the region of half or more of the non-fixed portion, and the problem that the tape member is broken or peeled unintentionally when wearing the absorbent article is effective. Can be suppressed.

The non-fixed portion 64 is provided on the other end 60 B side of the tape member 60. The non-fixed portion 64 is provided at the front end edge which is the other end 60B in the first direction D1. Note that at least a portion of the non-fixed portion may be disposed closer to the other end 60B than the center of the tape member 60 in the first direction. When the non-fixed portion is disposed on both sides in the first direction of the fixed portion, the non-fixed portion having a long length in the first direction constitutes the non-fixed portion of the present invention. That is, the non-fixed portion 64 may be provided on both sides in the first direction of the fixed portion 62. In this case, the non-fixed portion 64 having a long length in the first direction is the other end, and the non-fixed portion having a short length in the first direction is one end.
　非固定部６４は、裏面シート２２に固定されてなく、使用者がテープ部材６０を操作する部分である。より詳細には、使用者は、テープ部材６０を使用する際に、非固定部６４を把持して固定部６２を基点にして非固定部を折り返したり、非固定部６４を第１方向に伸長したりして、非固定部６４を本体部２０に止着する。非固定部６４の少なくとも一部は、使用者が把持可能な把持部を構成する。把持部は、非固定部６４全域であってもよいし、非固定部６４のうち、固定部６２とは反対側の一端側に設けられていてもよい。 The non-fixed portion 64 is a portion that is not fixed to the back sheet 22 and the user operates the tape member 60. More specifically, when using the tape member 60, the user holds the non-fixed portion 64 and folds the non-fixed portion around the fixed portion 62 or extends the non-fixed portion 64 in the first direction. As a result, the non-fixed portion 64 is fixed to the main body portion 20. At least a portion of the non-fixed portion 64 constitutes a gripping portion that can be gripped by the user. The grip portion may be the entire non-fixed portion 64 or may be provided on one end side of the non-fixed portion 64 opposite to the fixed portion 62.
　テープ部材６０は、固定部６２側に位置する一端６０Ａと、非固定部６４側の他端６０Ｂと、一端６０Ａから他端６０Ｂに向かって延びる一対の側縁６０Ｃと、を有する。 The tape member 60 has one end 60A located on the fixed portion 62 side, the other end 60B on the non-fixed portion 64 side, and a pair of side edges 60C extending from the one end 60A to the other end 60B.
　テープ部材６０は、吸収性物品１０の廃棄時に、吸収性物品の肌対向面側を内側にして巻かれた状態の本体部２０に止着し、吸収性物品１０が巻かれた状態を維持するように構成されてよい。テープ部材６０の非固定部６４は、本体部２０に対して止着可能に構成されている。非固定部６４が本体部２０に止着する構成は、粘着部７０であってもよいし、テープ部材６０に設けられた粘着剤やフック部材等の止着手段であってもよい。また、テープ部材６０の固定部６２が、本体部２０に対して止着可能に構成されてもよい。固定部６２が本体部２０に止着する構成は、本体部２０の粘着部であってもよいし、テープ部材６０に設けられた粘着剤やフック部材等の止着手段であってもよい。 The tape member 60 is fixed to the main body portion 20 in a state of being wound with the skin facing surface side of the absorbent article facing inward when the absorbent article 10 is discarded, and the absorbent article 10 is maintained in a wound state. It may be configured as follows. The non-fixed portion 64 of the tape member 60 is configured to be attachable to the main body portion 20. The configuration in which the non-fixed portion 64 is fixed to the main body portion 20 may be the adhesive portion 70 or may be a fixing means such as an adhesive provided on the tape member 60 or a hook member. Further, the fixing portion 62 of the tape member 60 may be configured to be attachable to the main body portion 20. The configuration in which the fixing portion 62 is fixed to the main body portion 20 may be an adhesive portion of the main body portion 20 or may be a fixing means such as an adhesive provided on the tape member 60 or a hook member.
　本実施の形態のテープ部材６０の非固定部６４は、粘着部７０を介して廃棄時に本体部２０に止着する。粘着部によってテープ部材６０が本体部２０に止着する構成にあっては、非固定部６４には、粘着剤等の止着手段が設けられていなくてよい。また、テープ部材６０は、ウイング粘着部４２及びフラップ粘着部５２の少なくとも一方に止着されてもよい。 The non-fixed portion 64 of the tape member 60 of the present embodiment is fixed to the main body portion 20 at the time of disposal via the adhesive portion 70. In the configuration in which the tape member 60 is fixed to the main body portion 20 by the adhesive portion, the non-fixed portion 64 may not be provided with a fixing means such as an adhesive. Also, the tape member 60 may be fixed to at least one of the wing adhesive portion 42 and the flap adhesive portion 52.
　テープ部材６０は、本体部２０の外縁２０Ｅよりも外側に延出可能に構成されている。本実施の形態のテープ部材６０は、固定部６２を基点に非固定部６４が折り返されることにより、非固定部６４の少なくとも一部が本体部２０の外縁２０Ｅよりも外側に延出する。図２に示すように、テープ部材６０は、折り返されていない状態において、本体部２０の外縁２０Ｅよりも内側に配置されてもよい。テープ部材６０は、肌対向面側から見ると、本体部２０に隠れた状態であってもよい。図４に示すように、テープ部材６０は、折り返された状態において、本体部２０の外縁２０Ｅよりも外側に延出してもよい。使用者は、吸収性物品１０の使用後に本体部２０を前後方向Ｌに巻いた後、テープ部材６０を本体部２０の外縁２０Ｅよりも外側に延出させ、本体部２０にテープ部材６０を止着することができる（図４参照）。 The tape member 60 is configured to be able to extend outside the outer edge 20E of the main body 20. In the tape member 60 according to the present embodiment, at least a part of the non-fixed portion 64 extends outward beyond the outer edge 20E of the main body portion 20 by the non-fixed portion 64 being folded back around the fixed portion 62. As shown in FIG. 2, the tape member 60 may be disposed inside the outer edge 20E of the main body 20 in the unfolded state. The tape member 60 may be hidden by the main body 20 when viewed from the skin facing surface side. As shown in FIG. 4, the tape member 60 may extend outside the outer edge 20 </ b> E of the main body 20 in the folded state. After the user winds the main body 20 in the front-rear direction L after use of the absorbent article 10, the tape member 60 is extended outside the outer edge 20E of the main body 20, and the tape member 60 is fixed to the main body 20. It can be worn (see FIG. 4).
　他の形態として、テープ部材は、伸長方向に伸長可能に構成されてもよい。この場合、使用者がテープ部材を引っ張ることによって、テープ部材が本体部２０の外縁２０Ｅよりも外側に延出する。ここで、「伸長」とは、「弾性変形」又は「塑性変形」による伸長を含む。一例として、テープ部材６０は、伸縮性シート、フィルムから構成されていてよい。更に別の例として、テープ部材は、Ｚ型に折り畳まれたシートから構成されていてもよい。この場合、使用者がテープ部材の先端を引っ張ることによって、折り畳まれたテープ部材が展開され、これによりテープ部材が本体部２０の外縁２０Ｅよりも外側に延出する。 As another form, the tape member may be configured to be extensible in the extension direction. In this case, when the user pulls the tape member, the tape member extends outward beyond the outer edge 20E of the main body 20. Here, "extension" includes extension by "elastic deformation" or "plastic deformation". As an example, the tape member 60 may be composed of a stretchable sheet or a film. As yet another example, the tape member may be comprised of a sheet folded in a Z-shape. In this case, when the user pulls on the tip of the tape member, the folded tape member is expanded, whereby the tape member extends outward beyond the outer edge 20E of the main body 20.
　このような構成によれば、吸収性物品１０の使用中においては、テープ部材６０は、裏面シート２２の非肌対向面側で本体部２０の外縁２０Ｅよりも内側に配置されているため、経血のような体液が付されない。使用者は、吸収性物品１０の使用後に、外側に延出させたテープ部材６０を粘着部７０等に止着することによって、吸収性物品１０を丸めた状態に維持することができる。ここで、テープ部材６０に経血のような体液が付着しないため、テープ部材６０と粘着部７０との接合力の低下、又はテープ部材の止着手段の接合力の低下を防止することができる。さらに、吸収性物品１０の使用中においては、テープ部材６０は、裏面シート２２の非肌対向面側に設けられ、本体部２０の外縁２０Ｅより外側へ延びていないため、テープ部材６０は、着用者の肌に直接当たらない。したがって、使用中の違和感や不快感を低減することができる。 According to such a configuration, during use of the absorbent article 10, the tape member 60 is disposed inside the outer edge 20E of the main body portion 20 on the non-skin facing surface side of the back sheet 22. No body fluids like blood. The user can maintain the absorbent article 10 in a rolled state by fastening the tape member 60 extended outward to the adhesive portion 70 or the like after use of the absorbent article 10. Here, since no body fluid such as menstrual blood adheres to the tape member 60, it is possible to prevent a reduction in the bonding strength between the tape member 60 and the adhesive unit 70 or a reduction in the bonding strength of the fastening means of the tape member. . Furthermore, during use of the absorbent article 10, the tape member 60 is provided on the non-skin facing surface side of the back sheet 22 and does not extend outside the outer edge 20E of the main body 20, so the tape member 60 is worn Does not hit the person's skin directly. Therefore, discomfort and discomfort during use can be reduced.
　テープ部材６０は、本体部２０の前後方向Ｌの中心よりも後側に設けられていることが好ましい。使用者は、通常吸収性物品１０を丸める際に、吸収性物品１０の前端縁Ｅ１又は後端縁かＥ２から前後方向Ｌに丸め始める。そのうち、約８割の使用者は、吸収性物品１０の前端縁Ｅ１から丸め始める。よって、テープ部材６０は、前後方向Ｌの中心に対して後側に位置する領域に設けられていることが好ましい。テープ部材６０の少なくとも一部は、吸収コア２３の後端縁を跨いで、または吸収コアの後端縁よりも後側に配置されてよい。 The tape member 60 is preferably provided on the rear side of the center of the main body portion 20 in the front-rear direction L. The user usually starts to roll in the front-rear direction L from the front end edge E1 or the rear end edge E2 of the absorbent article 10 when the absorbent article 10 is rolled up. Among them, about 80% of users start rounding from the front end edge E1 of the absorbent article 10. Therefore, it is preferable that the tape member 60 be provided in a region located on the rear side with respect to the center in the front-rear direction L. At least a portion of the tape member 60 may be disposed across the rear end edge of the absorbent core 23 or on the rear side of the rear end edge of the absorbent core.
　好ましくは、テープ部８０は、第１折り目Ｆ１～第３折り目Ｆ３のうちの最も後側の第２折り目Ｆ２よりも後側に設けられてよい。上述のように、約８割の使用者は、使用後の吸収性物品１０を前側から巻き始める。テープ部８０が第２折り目Ｆ２よりも後側に設けられていることにより、多くの使用者は、吸収性物品１０の前端縁Ｅ１から丸め始め、巻き終わり部分をテープ部８０によって止着できる。 Preferably, the tape portion 80 may be provided on the rear side of the rearmost second fold line F2 among the first fold line F1 to the third fold line F3. As described above, about 80% of users start winding the used absorbent article 10 from the front side. By providing the tape portion 80 behind the second fold line F 2, many users can start rounding from the front end edge E 1 of the absorbent article 10 and fasten the wound end portion with the tape portion 80.

The rear end edge that is the outer edge of the first adhesive portion 71 in the first direction D1 is located outside (rear side) in the front-rear direction than the front edge that is the inner edge of the non-fixed portion 64 in the first direction D1. You may In the width direction W which is the second direction, the tape member 60 and the non-fixed portion 64 may overlap. In addition, a plurality of adhesive portions may be disposed at intervals, may be disposed at intervals in the first direction, may be disposed at intervals in the second direction, or may be disposed in the first direction. And may be spaced apart in the second direction.
　図２に示すように、第１粘着部７１と非固定部６４が第２方向である幅方向Ｗにおいて重なる重複領域ＲＡが設けられてよい。重複領域ＲＡは、幅方向Ｗからの側面視にして第１粘着部７１と非固定部６４が重なる領域であってよい。非固定部６４の前端縁よりも第１粘着部７１が前側に延びている構成にあっては、重複領域ＲＡの前後方向Ｌの長さは、非固定部６４の前端縁と第１粘着部７１の後端縁との距離である。また、非固定部６４の後端縁よりも第１粘着部７１が後側に延びている構成にあっては、重複領域ＲＡの前後方向Ｌの長さは、非固定部６４の後端縁と第１粘着部７１の前端縁との距離である。 As shown in FIG. 2, an overlapping area RA in which the first adhesive portion 71 and the non-fixing portion 64 overlap in the width direction W which is the second direction may be provided. The overlapping area RA may be an area where the first adhesive portion 71 and the non-fixed portion 64 overlap in a side view from the width direction W. In a configuration in which the first adhesive portion 71 extends forward of the front end edge of the non-fixed portion 64, the length of the overlapping region RA in the front-rear direction L corresponds to the front end edge of the non-fixed portion 64 and the first adhesive portion 71 is the distance to the rear end edge. In addition, in a configuration in which the first adhesive portion 71 extends rearward with respect to the rear end edge of the non-fixed portion 64, the length of the overlapping region RA in the front-rear direction L is the rear end edge of the non-fixed portion 64. And the front end edge of the first adhesive portion 71.
　非固定部６４は、裏面シート２２に対して剥離可能に構成されているため、裏面シート２２から浮き上がり易く、意図せずにめくれたり剥がれたりするおそれがある。しかし、非固定部６４は、一対の第１粘着部７１によって挟まれている。一対の第１粘着部７１が着用物品（下着）に固定された際に、第１粘着部７１間に領域は、着用物品と裏面シート２２によって挟まれた状態が維持され、露出しない。そのため、吸収性物品１０の着用時に、意図せずにテープ部材６０が折れたり剥がれたりする不具合を抑制できる。 The non-fixed portion 64 is configured to be peelable with respect to the back surface sheet 22, so it is likely to be lifted from the back surface sheet 22, and there is a possibility that it may be accidentally peeled or peeled off. However, the non-fixed portion 64 is sandwiched by the pair of first adhesive portions 71. When the pair of first adhesive parts 71 is fixed to the wearing article (underwear), the region between the first adhesive parts 71 is maintained in a state of being sandwiched between the wearing article and the back sheet 22 and is not exposed. Therefore, when the absorbent article 10 is worn, it is possible to suppress a defect that the tape member 60 is unintentionally broken or peeled off.
　また、一対の第１粘着部７１が着用時に着用物品に固定されているため、吸収性物品１０が部分的にめくれた場合であっても、一対の第１粘着部及びその間の領域は、着用物品側に向かう状態が維持され、着用者の肌側に向かうように配置されない。一対の第１粘着部７１間の領域にテープ部材６０の非固定部６４が配置されているため、非固定部６４が肌によって擦れ難く、意図せずにテープ部材６０が折れたり剥がれたりする不具合を抑制できる。 In addition, since the pair of first adhesive portions 71 is fixed to the wearing article when worn, even when the absorbent article 10 is partially curled up, the pair of first adhesive portions and the region between them wear The condition toward the article side is maintained, and it is not arranged to face the wearer's skin side. Since the non-fixed portion 64 of the tape member 60 is disposed in the region between the pair of first adhesive portions 71, the non-fixed portion 64 is not easily rubbed by the skin, and the tape member 60 is broken or peeled unintentionally Can be suppressed.
非固定部６４のめくれ等の不具合を抑制するために、重複領域ＲＡの第１方向Ｄ１の長さは、非固定部６４の第１方向の全域に対する５０％以上であってよい。このような構成によれば、非固定部６４の半分以上の領域において非固定部のめくれや剥がれを抑制でき、吸収性物品の着用時に意図せずにテープ部材が折れたり剥がれたりする不具合を効果的に抑制できる。 In order to suppress a defect such as turning over of the non-fixed portion 64, the length of the overlapping area RA in the first direction D1 may be 50% or more of the entire area of the non-fixed portion 64 in the first direction. According to such a configuration, it is possible to suppress the turning off and peeling off of the non-fixed portion in the half or more region of the non-fixed portion 64, and it is effective to a defect that the tape member is broken or peeled unintentionally when wearing the absorbent article. Can be suppressed.
　より好適には、重複領域ＲＡの第１方向Ｄ１の長さは、非固定部６４の第１方向Ｄ１の長さであってよい。このような構成によれば、非固定部６４全域に亘って非固定部６４のめくれや剥がれを抑制でき、吸収性物品の着用時に意図せずにテープ部材が折れたり剥がれたりする不具合を効果的に抑制できる。 More preferably, the length of the overlapping region RA in the first direction D1 may be the length of the non-fixed portion 64 in the first direction D1. According to such a configuration, it is possible to suppress the turning off and peeling off of the non-fixed portion 64 over the entire non-fixed portion 64, and the problem that the tape member is broken or peeled unintentionally when wearing the absorbent article is effective. Can be suppressed.
　第１粘着部７１は、テープ部材６０の他端６０Ｂを第１方向Ｄ１において跨いでよい。第１粘着部７１は、テープ部材６０の他端６０Ｂよりも第１方向Ｄ１の外側に延びてよい。非固定部６４の一端６０Ａ側は、固定部６２が設けられているため、非固定部の一端側の端縁（前端縁）は、めくれ難い。一方、非固定部６４の他端６０Ｂ側の端縁（後端縁）は、比較的めくれ易い。テープ部材６０の他端６０Ｂは、非固定部６４の他端側の端縁（前端縁）である。当該テープ部材６０の他端６０Ｂを跨いで第１粘着部７１が延びているため、非固定部６４の他端側の端縁のめくれを抑制できる。 The first adhesive unit 71 may straddle the other end 60B of the tape member 60 in the first direction D1. The first adhesive portion 71 may extend to the outside of the first direction D1 more than the other end 60B of the tape member 60. Since the fixed portion 62 is provided on the one end 60A side of the non-fixed portion 64, the end edge (front end edge) of the one end side of the non-fixed portion is not easily flipped. On the other hand, the end edge (rear end edge) on the other end 60B side of the non-fixed portion 64 is relatively easy to flip. The other end 60 </ b> B of the tape member 60 is an end edge (front end edge) of the other end of the non-fixed portion 64. Since the first adhesive portion 71 extends across the other end 60B of the tape member 60, it is possible to suppress the turning of the end edge on the other end side of the non-fixed portion 64.
　粘着部７０は、第２粘着部７２を有してよい。第２粘着部は、第１粘着部間において第１方向に延びてよい。第２粘着部は、テープ部材６０の他端側に配置されてよい。第２粘着部７２は、第１方向である前後方向Ｌにおいてテープ部材６０に重なってよい。本実施の形態の第２粘着部７２は、テープ部材６０の前側に延びている。第２粘着部７２は、１列以上であればよい。第２粘着部７２によって、テープ部材の他端６０Ｂ側を着用物品に固定でき、非固定部６４の他端６０Ｂ側の端縁を保護できる。よって、非固定部６４の他端側の端縁のめくれを抑制できる。 The adhesive unit 70 may have a second adhesive unit 72. The second adhesive unit may extend in the first direction between the first adhesive units. The second adhesive unit may be disposed on the other end side of the tape member 60. The second adhesive portion 72 may overlap the tape member 60 in the front-rear direction L which is the first direction. The second adhesive portion 72 in the present embodiment extends to the front side of the tape member 60. The 2nd adhesion part 72 should just be one or more lines. The second adhesive portion 72 can fix the other end 60B side of the tape member to the worn article, and can protect the end edge of the non-fixed portion 64 on the other end 60B side. Therefore, it is possible to suppress the turning-off of the edge on the other end side of the non-fixed portion 64.
　また、着用前の状態においても、テープ部材６０を保護してもよい。具体的には、剥離シート７５の少なくとも一部は、テープ部材６０と厚み方向Ｔに重なる領域に配置されてよい。好適には、剥離シート７５は、非固定部と厚み方向に重なってよい。剥離シート７５は、テープ部材６０の他端６０Ｂである前端縁を覆ってよい。剥離シート７５の幅方向Ｗの長さは、テープ部材６０の幅方向Ｗの長さよりも長くてよい。テープ部材６０は、全幅に亘って剥離シートによって保護され、吸収性物品の使用前にテープ部材６０が意図せずに折れたり曲がったりすることを抑制できる。また、他の形態において、包装シートの少なくとも一部がテープ部材６０と厚み方向Ｔに重なる領域に配置されてもよい。 In addition, the tape member 60 may be protected also in a state before wearing. Specifically, at least a part of the release sheet 75 may be disposed in a region overlapping the tape member 60 in the thickness direction T. Preferably, the release sheet 75 may overlap the non-fixed portion in the thickness direction. The release sheet 75 may cover the front end edge which is the other end 60 B of the tape member 60. The length of the release sheet 75 in the width direction W may be longer than the length of the width direction W of the tape member 60. The tape member 60 is protected by the release sheet over the entire width, and can prevent the tape member 60 from being unintentionally bent or bent before the absorbent article is used. Further, in another embodiment, at least a part of the packaging sheet may be disposed in the area overlapping the tape member 60 in the thickness direction T.
次いで、他の実施形態に係る吸収性物品について説明する。なお、以下の説明において、上述の実施形態と同じ箇所については、同符号を用いて説明を省略する。図５は、変形例１に係る吸収性物品１０Ａの非肌対向面側から見た平面図である。 Then, the absorbent article which concerns on other embodiment is demonstrated. In the following description, the same parts as those of the above-described embodiment are denoted by the same reference numerals and the description thereof will be omitted. FIG. 5: is the top view seen from the non-skin opposing surface side of the absorbent article 10A which concerns on the modification 1. FIG.
　変形例１に係る吸収性物品１０Ａは、テープ部材の一端６０Ａがテープ部材の前端縁であり、テープ部材の他端６０Ｂがテープ部材の後端縁である。 In the absorbent article 10A according to the first modification, one end 60A of the tape member is a front end edge of the tape member, and the other end 60B of the tape member is a rear end edge of the tape member.
　第１粘着部７１は、テープ部材６０の一端６０Ａを第１方向に跨いでよい。第１粘着部７１は、テープ部材６０の一端６０Ａよりも第１方向Ｄ１においてテープ部材６０の外側に延びてよい。テープ部材６０の一端６０Ａは、固定部の一端側の端縁（後端縁）である。テープ部材６０の一端６０Ａを跨いで第１粘着部７１が延びているため、固定部６２の一端側の端縁を保護し、意図せずに固定部６２が剥がれる不具合を抑制できる。 The first adhesive unit 71 may straddle one end 60A of the tape member 60 in the first direction. The first adhesive portion 71 may extend to the outside of the tape member 60 in the first direction D1 more than one end 60A of the tape member 60. One end 60A of the tape member 60 is an end edge (rear end edge) of one end side of the fixing portion. Since the first adhesive portion 71 extends across the end 60A of the tape member 60, the end edge on one end side of the fixing portion 62 can be protected, and the problem of unintentional removal of the fixing portion 62 can be suppressed.
　粘着部７０は、第３粘着部７３を有してよい。第３粘着部７３は、第１粘着部７１間において第１方向に延びてよい。第３粘着部は、テープ部材の一端側に配置されてよい。第３粘着部７３は、第１方向である前後方向Ｌにおいてテープ部材６０に重なってよい。本実施の形態の第３粘着部７３は、テープ部材６０の前側に延びている。第３粘着部７３は、１列以上であればよい。第３粘着部７３によって、テープ部材の一端６０Ａ側を着用物品に固定でき、固定部６２の一端６０Ａ側の端縁を保護できる。よって、意図せずに固定部６２が剥がれる不具合を抑制できる。 The adhesive unit 70 may have a third adhesive unit 73. The third adhesive unit 73 may extend in the first direction between the first adhesive units 71. The third adhesive unit may be disposed on one end side of the tape member. The third adhesive portion 73 may overlap the tape member 60 in the front-rear direction L which is the first direction. The third adhesive portion 73 of the present embodiment extends to the front side of the tape member 60. The third adhesive unit 73 may be in one or more rows. The third adhesive portion 73 can fix the one end 60A side of the tape member to the wearing article, and can protect the end edge of the fixing portion 62 on the one end 60A side. Therefore, it is possible to suppress the problem that the fixing portion 62 is peeled off unintentionally.
　他の形態として、テープ部材６０の非固定部６４に仮固定部６６（図６参照）を設けてもよい。仮固定部６６は、本体部２０の非肌対向面である裏面シート２２に剥離可能に接合されてよい。仮固定部６６を設けることにより、テープ部材６０の使用前（製造時、着用時）に非固定部６４が捲れたり、非固定部６４が折れたりすることを抑制できる。 As another form, the non-fixed portion 64 of the tape member 60 may be provided with a temporary fixing portion 66 (see FIG. 6). The temporary fixing portion 66 may be releasably joined to the back sheet 22 which is the non-skin opposing surface of the main body portion 20. By providing the temporary fixing portion 66, it is possible to suppress that the non-fixed portion 64 is twisted or the non-fixed portion 64 is broken before using the tape member 60 (during manufacturing and wearing).
　仮固定部６６の接合力は、固定部６２の接合力よりも低くてよい。仮固定部６６の接合力が固定部６２の接合力よりも低いため、使用者は、テープ部材６０の使用時に容易に仮固定部６６を剥がし、非固定部６４を掴んでテープ部材６０を操作することができる。仮固定部６６の固定手段としては、接着剤、エンボス加工、熱溶着、超音波溶着を例示でき、固定部６２よりも接着剤の塗布量（面積、目付）を少なくしたり、固定部６２よりもエンボス加工の圧搾を弱くしたりできる。また、仮固定部６６は、本体部の外縁のエンボスによって構成されていてもよい。 The bonding force of the temporary fixing portion 66 may be lower than the bonding force of the fixing portion 62. Since the joining force of the temporary fixing part 66 is lower than the joining force of the fixing part 62, the user can easily peel off the temporary fixing part 66 when using the tape member 60 and grip the non-fixed part 64 to operate the tape member 60. can do. As a fixing means of the temporary fixing part 66, an adhesive, embossing, heat welding, ultrasonic welding can be exemplified, and the application amount (area, basis weight) of the adhesive is smaller than that of the fixing part 62. Can also weaken the squeezing of the embossing. Also, the temporary fixing portion 66 may be configured by embossing the outer edge of the main body portion.
　接合力は、引張試験機（インストロンジャパンカンパニイリミテッド製、型式 ５５４３）で測定可能である。例えば、接合力は次のように測定する。まず、引張試験機の上部固定部及び下部固定部に、テープ部材の試験片と裏面シートの試験片を固定する。上部固定部及び下部固定部に固定する試験片は幅１０ｍｍとする。上部固定部に固定する試験片と下部固定部に固定する試験片との間には、固定部６２に相当する固定面が形成されている。引張試験機の上部固定部と下部固定部との相対変位速度を１００ｍｍ／分に設定し、接合部を剥離している間の最大荷重点を接合力（接着強度）とする。 The bonding strength can be measured with a tensile tester (Model 5543, manufactured by Instron Japan Company Limited). For example, the bonding force is measured as follows. First, the test piece of the tape member and the test piece of the back sheet are fixed to the upper fixing portion and the lower fixing portion of the tensile tester. The test piece fixed to the upper fixed part and the lower fixed part shall be 10 mm in width. A fixing surface corresponding to the fixing portion 62 is formed between the test piece fixed to the upper fixing portion and the test piece fixed to the lower fixing portion. The relative displacement speed between the upper fixed part and the lower fixed part of the tensile testing machine is set to 100 mm / min, and the maximum load point while peeling the joint is taken as the bonding strength (adhesive strength).
　図６は、変形例２及び変形例３に係る吸収性物品のテープ部材であり、仮固定部６６の一例を示している。図６（ａ）は、変形例２に係るテープ部材６０Ｄの平面図であり、図６（ｂ）は、変形例３に係るテープ部材６０Ｅである。テープ部材６０Ｄ及びテープ部材６０Ｅには、接着剤が塗布された塗布領域が設けられている。塗布領域は、固定部６２に設けられた第１塗布領域Ｒ１と、非固定部６４の仮固定部６６に設けられた第２塗布領域Ｒ２と、を有してよい。第２塗布領域Ｒ２の面積率（単位面積当たりの塗布領域の面積の比率）は、第１塗布領域Ｒ１の面積率よりも低くてよい。第２塗布領域Ｒ２の接着剤の目付は、第１塗布領域Ｒ１の接着剤の目付よりも低くてよい。好適には、第２塗布領域Ｒ２の目付が低く、かつ第１塗布領域の面積率が低くてよい。第１塗布領域のＲ１の幅方向の長さは、第２塗布領域Ｒ２の幅方向の長さよりも長くてよい。第２塗布領域Ｒ２の幅方向の長さは、第１塗布領域Ｒ１から離れるにつれて短くなっている。すなわち、塗布領域の接着剤の塗布量は、テープ部材６０Ｄの一端６０Ａ側からテープ部材６０の他端６０Ｂに向かって小さくなっている。第２塗布領域Ｒ２は、接着剤が斑に塗布された領域や、図６（ｂ）に示すように接着剤が点状に塗布された領域を含んでよい。 FIG. 6 is a tape member of the absorbent article according to the second modification and the third modification, and shows an example of the temporary fixing portion 66. As shown in FIG. FIG. 6A is a plan view of a tape member 60D according to the second modification, and FIG. 6B is a tape member 60E according to the third modification. The tape member 60D and the tape member 60E are provided with an application region to which an adhesive is applied. The application region may have a first application region R1 provided in the fixed portion 62 and a second application region R2 provided in the temporary fixing portion 66 of the non-fixed portion 64. The area ratio of the second application region R2 (the ratio of the area of the application region per unit area) may be lower than the area ratio of the first application region R1. The basis weight of the adhesive in the second application region R2 may be lower than the basis weight of the adhesive in the first application region R1. Preferably, the basis weight of the second application region R2 may be low, and the area ratio of the first application region may be low. The length in the width direction of R1 of the first application area may be longer than the length in the width direction of the second application area R2. The length in the width direction of the second application region R2 decreases as the distance from the first application region R1 increases. That is, the application amount of the adhesive in the application region is reduced from the one end 60A side of the tape member 60D toward the other end 60B of the tape member 60. The second application area R2 may include an area in which the adhesive is applied to the spots, and an area in which the adhesive is applied in a dotted manner as shown in FIG. 6 (b).
　このような構成によれば、固定部６２の接合力を仮固定部６６の接合力よりも小さくできる。また、接着剤を塗布する工程では、接着剤を噴射するノズル等をテープ部材に当てた状態を維持し、ノズルから噴射する接着剤を調整すればよい。具体的には、固定部６２を設ける領域に向かって接着剤を噴射し、固定部６２の終端の領域において接着剤の噴射を止める。接着剤は、粘性があり、噴射を止めても直ちに噴射量が零にならず、徐々に噴射量が減る。この徐々に噴射量が減った接着剤によって仮固定部６６を構成できる。このような仮固定部６６においては、固定部６２から離れるにつれて徐々に接合力が小さくなっている。仮固定部６６の他端６０Ｂ側の端縁（非固定部６４側の端縁）は、テープ部材６０Ｄの他端６０Ｂに到達していてもよい。なお、仮固定部６６は、本発明にかかる第１粘着部７１と合わせて設けてよいし、本発明にかかる第１粘着部７１に代えて設けてもよい。 According to such a configuration, the bonding force of the fixing portion 62 can be smaller than the bonding force of the temporary fixing portion 66. Further, in the step of applying the adhesive, a state in which a nozzle or the like for jetting the adhesive is applied to the tape member may be maintained, and the adhesive ejected from the nozzle may be adjusted. Specifically, the adhesive is jetted toward the area where the fixing portion 62 is provided, and the jetting of the adhesive is stopped in the area of the end of the fixing portion 62. The adhesive is viscous, and the injection amount does not immediately become zero when the injection is stopped, and the injection amount gradually decreases. The temporary fixing portion 66 can be configured by the adhesive whose injection amount gradually decreases. In such a temporary fixing portion 66, the bonding force gradually decreases with distance from the fixing portion 62. The edge on the other end 60B side of the temporary fixing portion 66 (the edge on the non-fixed portion 64 side) may reach the other end 60B of the tape member 60D. The temporary fixing portion 66 may be provided together with the first adhesive portion 71 according to the present invention, or may be provided instead of the first adhesive portion 71 according to the present invention.
