Description

本発明は、生理用ナプキン等の吸収性物品に関する。   The present invention relates to an absorbent article such as a sanitary napkin.

従来、生理用ナプキン等の吸収性物品において、漏れ防止性や装着性を向上させるために、その肌対向面側に、表面シート及び吸収体が裏面シート側に向かって一体的に凹陥してなる溝を形成することが知られている。また、生理用ナプキン等の吸収性物品として、液保持性の吸収体を具備する本体と、該本体の縦方向に沿う両側部それぞれに配置された一対の立体ギャザーとを備えたものが知られている。また、このような溝を起点として、あるいは立体ギャザーの収縮力を利用して、吸収性物品の一部を肌対向面側に湾曲させ、その湾曲部を着用者の身体にフィットさせて漏れ防止を図る技術も知られている。   Conventionally, in an absorbent article such as a sanitary napkin, in order to improve leakage prevention and wearability, a top sheet and an absorber are integrally recessed toward the back sheet side on the skin facing surface side. It is known to form grooves. In addition, as an absorbent article such as a sanitary napkin, there is known an article provided with a main body having a liquid-retaining absorbent body and a pair of three-dimensional gathers arranged on both side portions along the longitudinal direction of the main body. ing. In addition, using such a groove as a starting point or using the shrinkage force of three-dimensional gathers, a part of the absorbent article is bent toward the skin facing surface, and the bent portion is fitted to the wearer's body to prevent leakage. Techniques for achieving this are also known.

例えば特許文献１には、吸収性物品の肌対向面で且つ吸収性物品の縦方向の前端部領域及び／又は後端部領域に、縦方向中心線を跨いで両側にそれぞれ、吸収性物品の端縁側に行くに従って漸次、該縦方向中心線に接近する線状エンボス（溝）を形成することが記載されている。特許文献１によれば、着用時にショーツ側から僅かな押圧力を受けることによって、吸収性物品における前記線状エンボスよりも縦方向外方に位置する前端部及び／又は後端部が、ショーツ（着用者の身体）のカーブ形状に沿った形状に折れ曲がり、平面視でショーツ形状に沿うように湾曲した形状となるため、身体との密着度が高まり前後漏れが防止されるとされている。   For example, in Patent Document 1, the absorbent article has a skin-facing surface and a longitudinal front end region and / or a rear end region of the absorbent article. It is described that linear embosses (grooves) that gradually approach the longitudinal center line are formed toward the end edge side. According to Patent Document 1, when receiving a slight pressing force from the shorts side during wearing, the front end portion and / or the rear end portion positioned outward in the longitudinal direction from the linear embossing in the absorbent article are shorts ( It is said that it is bent into a shape along the curve shape of the wearer's body) and curved so as to follow the shorts shape in a plan view, so that the degree of close contact with the body is increased and leakage before and after is prevented.

また特許文献２には、身体へのフィット性を向上させると共に、前漏れを効果的に防止する観点から、肌対向面側の両側部に縦方向の前後に沿って所定区間に亘り弾性伸縮部材による収縮力によって肌対向面側に起立する立体ギャザーを備えた吸収性物品において、該立体ギャザーの起立区間の略中心点を吸収性物品における体液排出部位よりも前方側に位置させ、該弾性伸縮部材の収縮力によって吸収性物品の前端部分を曲線状に起立させることが記載されている。   Patent Document 2 discloses an elastic elastic member over a predetermined section along the longitudinal direction on both sides on the skin facing surface side from the viewpoint of improving fit to the body and effectively preventing front leakage. In an absorbent article having a three-dimensional gather that stands on the skin-facing surface side due to the contraction force of the three-dimensional gather, the substantially central point of the standing section of the three-dimensional gather is positioned in front of the body fluid discharge site in the absorbent article, and the elastic expansion and contraction It is described that the front end portion of the absorbent article is raised in a curved shape by the contraction force of the member.

特許文献１に記載の吸収性物品は、前方部と排泄部対向部との境界又はその近傍に形成された、いわゆる防漏溝としての弧状エンボス（特許文献１の図１中符号８Ａで示される部分）とは別に、該エンボス８Ａよりも縦方向前側に、平面視してハの字状の前記線状エンボスを形成し、該線状エンボスによって吸収性物品の前端部を、着用時に強制的にショーツ形状に沿うように湾曲させているため、その湾曲した前端部は、全体的に硬くて動きの自由度が低く身体へのフィット性が十分とは言えず、結果として、前漏れ防止性の点で改良の余地があった。また、特許文献２に記載の吸収性物品においては、曲線状に起立した該吸収性物品の前端部分の肌対向面に、平面視して該吸収性物品の縦方向前端に向けて凸の略Ｕ字状のエンボス（溝）が形成されているところ、このエンボスの形成位置が立体ギャザーとの関係において適切でないため、曲線上に起立した前端部分は、身体へのフィット性が十分とは言えず、前漏れを効果的に防止し得るとは言い難い。   The absorbent article described in Patent Document 1 is an arc-shaped emboss as a so-called leak-proof groove formed at or near the boundary between the front part and the excretory part facing part (indicated by reference numeral 8A in FIG. 1 of Patent Document 1). Apart from the embossed portion 8A, the linear emboss is formed in the shape of a letter C in plan view in front of the emboss 8A, and the front end of the absorbent article is forced by the linear embossing when worn. Therefore, the curved front end is hard overall and has a low degree of freedom of movement, so it cannot be said that the body fits well. There was room for improvement. Further, in the absorbent article described in Patent Document 2, the skin facing surface of the front end portion of the absorbent article that stands up in a curved shape has a substantially convex shape toward the longitudinal front end of the absorbent article in plan view. When the U-shaped emboss (groove) is formed, the formation position of this emboss is not appropriate in relation to the three-dimensional gather. Therefore, it can be said that the front end portion standing on the curve has sufficient fit to the body. Therefore, it is difficult to say that the pre-leakage can be effectively prevented.

従って本発明の課題は、前漏れを効果的に防止し得る吸収性物品を提供することにある。   Therefore, the subject of this invention is providing the absorbent article which can prevent pre-leakage effectively.

本発明は、肌対向面を形成する表面シート、非肌対向面を形成する裏面シート及び両シート間に介在された吸収体を具備する本体を備え、着用者の前後方向に相当する縦方向とこれに直交する横方向とを有し、着用時に着用者の排泄部に対向配置される排泄部対向部と、該排泄部対向部よりも着用者の腹側に配される前方部と、該排泄部対向部よりも着用者の背側に配される後方部とを縦方向に有する吸収性物品であって、前記前方部における前記本体の肌対向面に、前記表面シート及び前記吸収体が前記裏面シート側に向かって一体的に凹陥してなる線状の溝として、縦方向に延びる一対の縦溝と、該縦溝の縦方向前端から連続し横方向内方に延びる横溝とが形成されており、前記本体の縦方向に沿う左右両側部に、少なくとも前記排泄部対向部において着用時に着用者の肌側に向かって起立する一対の立体ギャザーが設けられており、該立体ギャザーは、基壁部と、該基壁部の上端部に連接され、縦方向に沿って弾性部材が伸長状態で配されている弾性伸縮部とを含んで構成されており、前記弾性伸縮部は、前記基壁部の上端部から横方向外方に張り出しており、該弾性伸縮部の縦方向に沿う内側縁は該上端部に連接され、該弾性伸縮部の縦方向に沿う外側縁は、前記吸収性物品の他の構成部材と接合されておらず、自由側縁を形成しており、前記前方部及び前記後方部には、それぞれ、前記立体ギャザーの縦方向の端部における前記弾性伸縮部が前記本体に接合されその伸縮性が阻害された、非伸縮領域と、該非伸縮領域よりも縦方向内方に位置する、該弾性伸縮部の伸縮性が阻害されていない伸縮領域とが存しており、前記前方部における前記非伸縮領域と前記伸縮領域との境界は、縦方向において、前記横溝の縦方向前端と同位置か又は該縦方向前端よりも縦方向後側に位置している吸収性物品を提供することにより、前記課題を解決したものである。   The present invention comprises a main body comprising a top sheet that forms a skin-facing surface, a back sheet that forms a non-skin-facing surface, and an absorbent body interposed between both sheets, and a longitudinal direction that corresponds to the front-rear direction of the wearer. A lateral direction perpendicular to this, and an excretion part facing part disposed opposite to the excretion part of the wearer when worn, a front part disposed on the abdomen side of the wearer from the excretion part facing part, It is an absorbent article having a rear portion arranged on the back side of the wearer rather than the excretory portion facing portion in the longitudinal direction, and the topsheet and the absorber are on the skin facing surface of the main body in the front portion. A pair of vertical grooves extending in the vertical direction and a horizontal groove extending inward in the horizontal direction from the longitudinal front end of the vertical groove are formed as linear grooves that are integrally recessed toward the back sheet side. At least the excretory part on the left and right side parts along the longitudinal direction of the main body. A pair of three-dimensional gathers are provided to stand toward the wearer's skin when worn in the facing portion, and the three-dimensional gathers are connected to the base wall portion and the upper end portion of the base wall portion, along the longitudinal direction. The elastic member includes an elastic expansion / contraction part arranged in an extended state, and the elastic expansion / contraction part protrudes laterally outward from the upper end of the base wall part, and the elastic expansion / contraction part The inner edge along the longitudinal direction is connected to the upper end, and the outer edge along the longitudinal direction of the elastic stretchable part is not joined to other components of the absorbent article and forms a free side edge. A non-stretchable region in which the elastic stretchable portion at the longitudinal end of the three-dimensional gather is joined to the main body and its stretchability is inhibited; and the non-stretchable portion Elasticity of the elastic elastic part located inward in the vertical direction from the region There is an unhindered stretchable region, and the boundary between the non-stretchable region and the stretchable region in the front portion is placed in the vertical direction with the longitudinal front end of the horizontal groove or from the longitudinal front end. Also, the problem is solved by providing an absorbent article located on the rear side in the longitudinal direction.

That is, in the front end side region A1 of the napkin 1 (main body 5), the left and right side portions in the lateral direction Y are in a region near the center in the width direction Y (hereinafter referred to as the center region) sandwiched between the left and right side portions. On the other hand, it deform | transforms so that it may be located to the skin opposing surface side (surface sheet 2 side), and as a result of the deformation | transformation, the center area | region is depressed and the hollow part S is formed. In addition, in FIG. 5, a pair of substantially eight-shaped curved lines described as the boundary line of the hollow part S are drawn lines for expressing the hollow part S and the three-dimensional shape around it. It is not intentionally formed like the linear groove according to the invention, and such a curved line is not always actually formed. The front end side area A1 is configured to include the top sheet 2, the back sheet 3, and the absorber 4 (lower layer absorber 45) interposed between both sheets 2 and 3, and the recess S is configured in the same manner. Has been. This recess S fits flexibly to the front side (abdominal side) of the wearer's body and forms a pocket-like structure, thereby effectively preventing front leakage.

窪み部Ｓの形成には、立体ギャザー１０（弾性伸縮部１２）と、前方部Ａに形成された線状の溝である一対の縦溝５１，５１及び横溝５２が、以下に述べるように、特に大きな役割を果たす。まず、ナプキン１の着用時において、縦方向Ｘに伸縮性を有する弾性伸縮部１２，１２による縦方向Ｘの引張力により、少なくとも排泄部対向部Ｂにおいて、図２に示すように、基壁部１１（起立部１４）が接合部１３を起点として着用者の肌側に向かって起立する。その基壁部１１が起立する際、横溝５２が、本体５をその部分で表面シート２側に折れ曲がり易くする可撓軸として作用する。また、前述したように、一対の弾性伸縮部１２，１２が、それぞれ、基壁部１１の上端部１１ａから横方向Ｙの外方に張り出した形状（弾性伸縮部１２を構成するサイドシート１６が横方向Ｙの外方側に折り曲げられた外折形状）を有していることに起因して、基壁部１１の起立の際、一対の弾性伸縮部１２，１２それぞれの外側縁１２ｑ（自由側縁）が横方向Ｙの内方に強く引っ張られる。それによって、一対の縦溝５１，５１、特に縦方向前端５１ａ，５１ａ及びその近傍が横方向Ｙの内方に引っ張られ、横溝５２にその引張力が作用する。このような、弾性伸縮部１２と縦溝５１及び横溝５２との横方向内方への連動した動きは、後述するように、横溝５２が弾性伸縮部１２との関係において適切に配置されて初めて発現する。このように、立体ギャザー１０の基壁部１１が起立する際には、横溝５２が可撓軸として作用すると共に、該横溝５２の近傍に位置する一対の縦溝５１，５１それぞれに、弾性伸縮部１２の外折形状に起因して、該縦溝５１を横方向Ｙの内方へ引っ張る力が作用するため、図５に示すように、本体５の前端側領域Ａ１が、前方横溝５２又はその近傍で表面シート２側に折れ曲がって湾曲し、一対の縦溝の縦方向前端５１ａ，５１ａの先端部から縦方向Ｘの前側において窪み部Ｓが形成される。   For the formation of the hollow portion S, a three-dimensional gather 10 (elastic stretchable portion 12) and a pair of vertical grooves 51, 51 and a horizontal groove 52, which are linear grooves formed in the front portion A, are described below. It plays a particularly big role. First, when the napkin 1 is worn, as shown in FIG. 2, at least in the excretory part-facing part B by the tensile force in the vertical direction X by the elastic elastic parts 12, 12 having elasticity in the vertical direction X, as shown in FIG. 11 (standing part 14) stands up toward the wearer's skin with the joint 13 as a starting point. When the base wall portion 11 stands up, the lateral groove 52 acts as a flexible shaft that makes it easy to bend the main body 5 toward the topsheet 2 at that portion. In addition, as described above, the pair of elastic stretchable portions 12, 12 protrude from the upper end portion 11 a of the base wall portion 11 outward in the lateral direction Y (the side sheets 16 constituting the elastic stretchable portion 12 are When the base wall portion 11 stands up due to the fact that it has an outward folding shape that is bent outward in the lateral direction Y, the outer edges 12q of each of the pair of elastic elastic portions 12, 12 (free Side edge) is strongly pulled inward in the lateral direction Y. Accordingly, the pair of vertical grooves 51, 51, particularly the vertical front ends 51 a, 51 a and the vicinity thereof are pulled inward in the horizontal direction Y, and the tensile force acts on the horizontal grooves 52. The movement of the elastic expansion / contraction part 12 and the longitudinal groove 51 and the lateral groove 52 interlocked inward in the lateral direction is not until the lateral groove 52 is properly arranged in relation to the elastic expansion / contraction part 12 as will be described later. To express. Thus, when the base wall portion 11 of the three-dimensional gather 10 stands, the lateral groove 52 acts as a flexible shaft and elastically expands and contracts in each of the pair of longitudinal grooves 51, 51 located in the vicinity of the lateral groove 52. Due to the outer folding shape of the portion 12, a force that pulls the longitudinal groove 51 inward in the lateral direction Y acts, so that as shown in FIG. In the vicinity thereof, the surface sheet 2 is bent and curved, and a recess S is formed on the front side in the vertical direction X from the front ends of the vertical front ends 51a and 51a of the pair of vertical grooves.

前述したように、窪み部Ｓの形成には、一対の弾性伸縮部１２，１２それぞれが、基壁部１１の上端部１１ａから横方向Ｙの外方に張り出した形状（外折形状）を有していることが必要であるから、弾性伸縮部１２が外折形状以外の他の形状を有している場合は、窪み部Ｓは形成され難い。例えば、弾性伸縮部が、基壁部の上端部から横方向の外方に張り出す外方弾性伸縮部と内方に張り出す内方弾性伸縮部とから構成され、図２に示す如き横方向に沿う断面視において、基壁部の起立部と合わせてＴ字状を形成するように起立する場合は、前述した、縦溝５１（横溝５２）を横方向Ｙの内方へ引っ張る引張力が発生し難いため、窪み部Ｓは形成され難い。   As described above, the recess S is formed in such a manner that each of the pair of elastic stretchable portions 12, 12 protrudes outward in the lateral direction Y from the upper end portion 11 a of the base wall portion 11. Therefore, when the elastic stretchable part 12 has a shape other than the outer folded shape, the recessed part S is hardly formed. For example, the elastic expansion / contraction part is composed of an outer elastic expansion / contraction part that protrudes outward in the lateral direction from the upper end of the base wall part, and an inward elastic expansion / contraction part that protrudes inward, as shown in FIG. In the cross-sectional view taken along the line, when standing up so as to form a T shape together with the upright portion of the base wall portion, the above-described tensile force pulling the longitudinal groove 51 (lateral groove 52) inward in the lateral direction Y is applied. Since it is hard to generate | occur | produce, the hollow part S is hard to be formed.

また、前述したように、窪み部Ｓの形成には、縦溝５１及び横溝５２が弾性伸縮部１２との関係において適切に配置されることも必要であり、具体的には、前方部Ａにおける弾性伸縮部１２の前側非伸縮領域１２Ａと伸縮領域１２Ｃとの境界１２Ｄが、縦方向Ｘにおいて、横溝５２の縦方向前端（横溝５２の凸の頂部）５２ａと同位置か又は縦方向前端５２ａよりも縦方向Ｘの後側に位置していることが必要である。本実施形態においては、図１に示すように、境界１２Ｄは、縦方向Ｘにおいて、横溝５２の縦方向前端５２ａと同位置にある。境界１２Ｄが、縦方向Ｘにおいて、横溝５２の縦方向前端５２ａよりも縦方向Ｘの前側に位置していると、前述した、弾性伸縮部１２と縦溝５１及び横溝５２との横方向Ｙの内方への連動した動きが発現し難く、窪み部Ｓが形成され難い。   In addition, as described above, the formation of the recessed portion S also requires that the vertical groove 51 and the horizontal groove 52 be appropriately disposed in relation to the elastic stretchable portion 12, and specifically, in the front portion A. The boundary 12D between the front non-stretchable region 12A and the stretchable region 12C of the elastic stretchable portion 12 is placed in the longitudinal direction X with the longitudinal front end (convex top portion of the lateral groove 52) 52a of the lateral groove 52 or from the longitudinal front end 52a. Is also required to be located on the rear side in the vertical direction X. In the present embodiment, as shown in FIG. 1, the boundary 12 </ b> D is in the same position as the longitudinal front end 52 a of the lateral groove 52 in the longitudinal direction X. When the boundary 12D is located in the longitudinal direction X in front of the longitudinal direction end 52a of the lateral groove 52 in the longitudinal direction X, the elastic expansion / contraction part 12, the longitudinal groove 51, and the lateral groove 52 in the lateral direction Y described above. The inwardly linked movement is difficult to appear and the hollow portion S is difficult to be formed.

前側非伸縮領域１２Ａと伸縮領域１２Ｃとの境界１２Ｄが、縦方向Ｘにおいて、横溝５２の縦方向前端５２ａよりも縦方向Ｘの後側に位置している場合、境界１２Ｄと横溝５２の縦方向前端５２ａとの縦方向Ｘにおける離間距離は、好ましくは１０ｍｍ以内、更に好ましくは５ｍｍ以内である。   When the boundary 12D between the front non-stretchable region 12A and the stretchable region 12C is located behind the longitudinal front end 52a of the lateral groove 52 in the longitudinal direction X, the longitudinal direction of the boundary 12D and the lateral groove 52 The distance in the longitudinal direction X from the front end 52a is preferably within 10 mm, more preferably within 5 mm.

吸収体４（下層吸収体４５）における前端側領域Ａ１（横溝５２から縦方向Ｘの前側に位置する領域）に位置する部分には、横方向Ｙに延びる可撓軸が形成されている。横方向Ｙに延びる可撓軸は、吸収体４（下層吸収体４５）を、その部分で縦方向Ｘに折れ曲がり易くし、窪み部Ｓがより確実に形成されるようにするものである。本実施形態においては、図５に示すように、吸収体４（下層吸収体４５）における横溝５２の形成部分（横溝５２）が可撓軸として機能する。   A flexible shaft extending in the horizontal direction Y is formed in a portion of the absorber 4 (lower layer absorber 45) located in the front end side area A1 (area located on the front side in the vertical direction X from the horizontal groove 52). The flexible shaft extending in the lateral direction Y makes the absorbent body 4 (lower layer absorbent body 45) easily bendable in the longitudinal direction X at that portion, so that the recess S is more reliably formed. In this embodiment, as shown in FIG. 5, the formation part (lateral groove 52) of the horizontal groove 52 in the absorber 4 (lower layer absorber 45) functions as a flexible shaft.

尚、前記可撓軸の形成方法としては、本実施形態のように、ｉ）吸収体にエンボス加工等により溝を形成し、その溝を可撓軸とする方法の他に、例えば、ｉｉ）吸収体にスリットや細幅の欠落部、切れ込み等を形成し、それらを可撓軸とする方法、ｉｉｉ）吸収体に、連続線又は断続線状に、構成材料を減少させた部分を形成し、その部分を可撓軸とする方法等が挙げられ、本発明では、これらの方法の１つ又は２つ以上を組み合わせて用いることができる。   As the method for forming the flexible shaft, as in this embodiment, in addition to the method in which i) a groove is formed in the absorbent body by embossing or the like and the groove is used as the flexible shaft, for example, ii) A method of forming slits, narrow missing parts, cuts, etc. in the absorbent body and using them as flexible shafts, iii) Forming a part of the absorbent body with reduced constituent materials in a continuous line or intermittent line form In the present invention, one or a combination of two or more of these methods can be used.

可撓軸として機能する横溝５２の深さは、好ましくは１ｍｍ以上、更に好ましくは２ｍｍ以上、そして、好ましくは１０ｍｍ以下、更に好ましくは５ｍｍ以下、より具体的には、好ましくは１ｍｍ以上１０ｍｍ以下、更に好ましくは２ｍｍ以上５ｍｍ以下である。尚、横溝５２の深さは、表面シート２における凹陥していない肌当接面２ａからの、横溝５２の凹陥深さを意味する。   The depth of the lateral groove 52 functioning as a flexible shaft is preferably 1 mm or more, more preferably 2 mm or more, and preferably 10 mm or less, more preferably 5 mm or less, more specifically preferably 1 mm or more and 10 mm or less, More preferably, it is 2 mm or more and 5 mm or less. In addition, the depth of the horizontal groove 52 means the recessed depth of the horizontal groove 52 from the skin contact surface 2a which is not recessed in the surface sheet 2. FIG.

尚、本発明に係る溝の各部の寸法（幅、深さ等）は、肉眼で定規等を使って測定しても良いが、好ましくは、高速・高精度ＣＣＤレーザー変位形を設置した高精度形状測定システムＫＳ−１１００（キーエンス社製）を用いて測定する。測定ピッチ５μm、移動速度１０ｃｍ／ｓとし、表面シートにおける凹陥していない肌対向面及び測定対象の溝を全て含むように測定範囲を指定し測定する。測定したデータを、前記ＫＳ−１１００付属の形状解析アプリケーションＫＳ−Ａｎａｌｙｚｅｒ（キーエンス社製）を用いて解析することにより、溝の各部の寸法を算出することができる。   The dimensions (width, depth, etc.) of each part of the groove according to the present invention may be measured with a naked eye using a ruler or the like, but preferably, a high accuracy with a high-speed, high-precision CCD laser displacement type installed. Measurement is performed using a shape measurement system KS-1100 (manufactured by Keyence Corporation). A measurement pitch is set to 5 μm, a moving speed is 10 cm / s, and a measurement range is specified and measured so as to include all of the skin facing surface and the measurement target groove in the top sheet. By analyzing the measured data using the shape analysis application KS-Analyzer (manufactured by Keyence Corporation) attached to the KS-1100, the dimensions of each part of the groove can be calculated.

本実施形態においては、図１に示すように、排泄部対向中高領域４１（前側上層吸収体４６）の縦方向後端４１ｂは、後方部Ｃにおける立体ギャザー１０（弾性伸縮部１２）の非伸縮領域１２Ｂと伸縮領域１２Ｃとの境界１２Ｅよりも縦方向Ｘの前側に位置し、且つ排泄部対向中高領域４１の縦方向後端４１ｂと後方部Ｃにおける境界１２Ｅとの離間距離Ｐ（図１参照）は、立体ギャザー１０の起立高さＱ（図２参照）よりも長くなっている。ここで、「立体ギャザーの起立高さ」とは、ナプキン１の自然状態における、弾性伸縮部１２の外側縁１２ｑ（自由側縁）の、表面シート２の肌対向面２ａ（中高領域が形成されている場合は、その中高領域における肌対向面）からの高さを意味する。立体ギャザー１０の起立高さが部分的に異なる場合、起立高さＱは、該起立高さが最大の部分におけるその最大起立高さである。ナプキン１が斯かる構成を具備することにより、立体ギャザー１０が起立し易くなるため、立体ギャザー１０による防漏効果がより確実に奏されるようになると共に、窪み部Ｓの形成が一層容易になる。   In the present embodiment, as shown in FIG. 1, the longitudinal rear end 41 b of the excretion-part-facing middle / high region 41 (front upper layer absorber 46) is not stretched of the three-dimensional gather 10 (elastic stretchable part 12) in the rear part C. A distance P between the vertical rear end 41b of the excretory part-facing middle and high region 41 and the boundary 12E at the rear part C (see FIG. 1), which is located in front of the boundary 12E between the region 12B and the stretchable region 12C. ) Is longer than the standing height Q of the three-dimensional gather 10 (see FIG. 2). Here, the “standing height of the three-dimensional gather” means that the skin facing surface 2a (middle height region) of the top sheet 2 of the outer edge 12q (free side edge) of the elastic stretchable part 12 in the natural state of the napkin 1 is formed. If it is, it means the height from the skin facing surface in the middle-high area. When the standing heights of the three-dimensional gathers 10 are partially different, the standing height Q is the maximum standing height at the portion where the standing height is the maximum. Since the napkin 1 has such a configuration, the three-dimensional gather 10 can easily stand up, so that the leak-proof effect of the three-dimensional gather 10 can be more reliably achieved, and the formation of the recessed portion S is further facilitated. Become.

また、本実施形態においては、図１に示すように、排泄部対向中高領域４１（前側上層吸収体４６）の縦方向前端４１ａは、前方部Ａにおける立体ギャザー１０（弾性伸縮部１２）の非伸縮領域１２Ａと伸縮領域１２Ｃとの境界１２Ｄよりも縦方向Ｘの後側に位置している。ナプキン１が斯かる構成を具備することにより、前述した、排泄部対向中高領域４１の縦方向後端４１ｂと境界１２Ｅとの特定の位置関係の採用による作用効果と相俟って、立体ギャザー１０の起立性及びそれによる防漏効果が一層確実に奏されるようになると共に、窪み部Ｓの形成がより一層容易になる。   Further, in the present embodiment, as shown in FIG. 1, the longitudinal front end 41 a of the excretion-part-facing middle-high region 41 (front-side upper layer absorbent body 46) is not in the three-dimensional gather 10 (elastic stretchable part 12) in the front part A. It is located on the rear side in the vertical direction X with respect to the boundary 12D between the stretchable region 12A and the stretchable region 12C. When the napkin 1 has such a configuration, the three-dimensional gather 10 is combined with the above-described operational effect by adopting a specific positional relationship between the vertical rear end 41b of the excretion portion facing middle and high region 41 and the boundary 12E. As a result, it is possible to more reliably achieve the stand-up property and the leakage prevention effect, and to further facilitate the formation of the recessed portion S.

排泄部対向中高領域４１の縦方向後端４１ｂと後方部Ｃにおける境界１２Ｅとの離間距離Ｐ（図１参照）は、好ましくは５ｍｍ以上、更に好ましくは１０ｍｍ以上、そして、好ましくは１００ｍｍ以下、更に好ましくは６０ｍｍ以下、より具体的には、好ましくは５ｍｍ以上１００ｍｍ以下、更に好ましくは１０ｍｍ以上６０ｍｍ以下である。
立体ギャザー１０の起立高さＱ（図２参照）は、好ましくは１ｍｍ以上、更に好ましくは２ｍｍ以上、そして、好ましくは４０ｍｍ以下、更に好ましくは３５ｍｍ以下、より具体的には、好ましくは１ｍｍ以上４０ｍｍ以下、更に好ましくは２ｍｍ以上３０ｍｍ以下である。
離間距離Ｐと起立高さＱとの差（Ｐ−Ｑ）は、好ましくは４ｍｍ以上６０ｍｍ以下、更に好ましくは８ｍｍ以上３０ｍｍ以下である。 The separation distance P (see FIG. 1) between the longitudinal rear end 41b of the excretory part facing middle and high region 41 and the boundary 12E in the rear part C is preferably 5 mm or more, more preferably 10 mm or more, and preferably 100 mm or less, The thickness is preferably 60 mm or less, more specifically, preferably 5 mm or more and 100 mm or less, and more preferably 10 mm or more and 60 mm or less.
The standing height Q (see FIG. 2) of the three-dimensional gather 10 is preferably 1 mm or more, more preferably 2 mm or more, and preferably 40 mm or less, more preferably 35 mm or less, more specifically preferably 1 mm or more and 40 mm.

本実施形態においては、図６に示すように、吸収体４（下層吸収体４５）における窪み部Ｓ（横溝５２から縦方向Ｘの前側に位置する前端側領域Ａ１）に位置する部分の肌対向面４ａに、ドット状の凹部４８が多数散点的に形成されている。ドット状の凹部４８は、平面視して略真円状をなし、下層吸収体４５における窪み部Ｓ（前端側領域Ａ１）に位置する部分の全域に均一に形成されている。凹部４８は、下層吸収体４５の肌対向面４ａと非肌対向面（図示せず）との間に底部を有しており、下層吸収体４５を厚み方向に貫通する貫通孔ではない。凹部４８は、下層吸収体４５のみに形成されていて、表面シート２には形成されておらず、従って、ナプキン１の肌対向面側を目視しても、凹部４８は確認し難い。このように、下層吸収体４５における窪み部Ｓに位置する部分にドット状の凹部４８が多数散点的に形成されていると、該部分の柔軟性が高まるため、窪み部Ｓの形成が一層容易になる。凹部４８は、熱を伴うか又は伴わないエンボス、あるいは超音波エンボス等のエンボス加工により常法に従って形成することができる。   In the present embodiment, as shown in FIG. 6, the skin facing part of the absorbent body 4 (the lower layer absorbent body 45) located in the depression S (front end side region A <b> 1 located on the front side in the longitudinal direction X from the lateral groove 52). A large number of dot-like recesses 48 are formed in a scattered manner on the surface 4a. The dot-shaped recess 48 has a substantially perfect circle shape when seen in a plan view, and is uniformly formed in the entire region of the lower layer absorber 45 located in the recess S (front end side region A1). The recess 48 has a bottom portion between the skin facing surface 4a and the non-skin facing surface (not shown) of the lower layer absorber 45, and is not a through-hole penetrating the lower layer absorber 45 in the thickness direction. The concave portion 48 is formed only in the lower layer absorbent body 45 and is not formed in the topsheet 2. Therefore, even when the skin facing surface side of the napkin 1 is visually observed, the concave portion 48 is difficult to confirm. In this way, when a large number of dot-like recesses 48 are formed in the portion located in the recess portion S in the lower layer absorber 45, the flexibility of the portion increases, so that the formation of the recess portion S is further increased. It becomes easy. The concave portion 48 can be formed according to a conventional method by embossing such as embossing with or without heat, or ultrasonic embossing.

ドット状の凹部４８の直径は、好ましくは０．１ｍｍ以上、更に好ましくは０．２ｍｍ以上、そして、好ましくは５０ｍｍ以下、更に好ましくは２０ｍｍ以下、より具体的には、好ましくは０．１ｍｍ以上５０ｍｍ以下、更に好ましくは０．２ｍｍ以上２０ｍｍ以下である。
ドット状の凹部４８の単位面積（１ｃｍ2）当たりの個数は、好ましくは０．０１個以上、更に好ましくは０．０８個以上、そして、好ましくは３１８５個以下、更に好ましくは７９６個以下、より具体的には、好ましくは０．０１個以上３１８５個以下、更に好ましくは０．０８個以上７９６個以下である。 The diameter of the dot-shaped recess 48 is preferably 0.1 mm or more, more preferably 0.2 mm or more, and preferably 50 mm or less, more preferably 20 mm or less, more specifically preferably 0.1 mm or more and 50 mm. Hereinafter, it is more preferably 0.2 mm or more and 20 mm or less.
The number of the dot-shaped concave portions 48 per unit area (1 cm 2 ) is preferably 0.01 or more, more preferably 0.08 or more, and preferably 3185 or less, more preferably 796 or less, and more. Specifically, it is preferably 0.01 or more and 3185 or less, more preferably 0.08 or more and 796 or less.

本実施形態においては、図１、図５及び図６に示すように、表面シート２の肌対向面２ａに、縦方向Ｘ及び横方向Ｙそれぞれに交差する方向に延びる線状の凹部２１が格子状に形成されており、凹部２１によって表面シート２が多数の領域に区画化されている。凹部２１は、表面シート２に設けられるものであり、吸収体４と一体的に設けられるものではなく、縦溝５１、横溝５２、湾曲溝５３，５４，５５とは異なるものである。凹部２１は、表面シート２の肌対向面２ａの全域に形成されている。凹部２１によって区画化された領域は、該凹部２１よりも着用者の肌側に突出した凸部となっている。凹部２１は、表面シート２の構成繊維が圧着又は接着されて形成されている。繊維を圧着する手段としては、熱を伴うか又は伴わないエンボス加工、超音波エンボス加工等が挙げられる。   In the present embodiment, as shown in FIGS. 1, 5, and 6, linear concave portions 21 extending in the direction intersecting the vertical direction X and the horizontal direction Y are latticed on the skin facing surface 2 a of the topsheet 2. The topsheet 2 is partitioned into a large number of regions by the recesses 21. The recess 21 is provided in the top sheet 2 and is not provided integrally with the absorber 4, and is different from the vertical groove 51, the horizontal groove 52, and the curved grooves 53, 54, and 55. The concave portion 21 is formed in the entire area of the skin facing surface 2a of the topsheet 2. The region partitioned by the concave portion 21 is a convex portion that protrudes more toward the wearer's skin than the concave portion 21. The concave portion 21 is formed by pressure bonding or bonding the constituent fibers of the topsheet 2. Examples of means for crimping the fibers include embossing with or without heat, ultrasonic embossing, and the like.

このように、表面シート２の肌対向面２ａに、縦方向Ｘ及び横方向Ｙの両方向に交差する方向に延びる線状の凹部２１が格子状に形成されていると、ナプキン１の自然状態あるいは着用時において、ナプキン１（本体５）の前端側領域Ａ１に、該前端側領域Ａ１を凹部２１の線状方向（縦方向Ｘ及び横方向Ｙの両方向に交差する方向）に沿ってナプキン１の内方側に引っ張る引張力が作用し易くなるため、該前端側領域Ａ１が表面シート２側に湾曲し易くなり、窪み部Ｓの形成が容易となる。加えて、窪み部Ｓとその左右両側に位置する一対の立体ギャザー１０，１０とによって一体的に構成される、カップ状の構造の形成が一層容易になり、フィット性と防漏性が一層向上する。仮に、線状の凹部２１が縦方向Ｘ又は横方向Ｙに延びている場合は、このような凹部２１による前端側領域Ａ１の折り曲げ誘導効果は発現し難い。また、表面シート２の肌対向面２ａに線状の凹部２１が格子状に形成されていることの別の利点として、肌対向面２ａにこのような格子状の模様が全く形成されていない場合に比して、窪み部Ｓの形状や、前記カップ状の構造の形成を目視で容易に確認し易い点が挙げられる。   Thus, when the linear recessed part 21 extended in the direction which cross | intersects both the vertical direction X and the horizontal direction Y is formed in the skin opposing surface 2a of the surface sheet 2, the natural state of the napkin 1 or At the time of wearing, the front end side area A1 of the napkin 1 (main body 5) is placed on the napkin 1 along the linear direction of the recess 21 (direction intersecting both the vertical direction X and the horizontal direction Y). Since the tensile force pulling inward is likely to act, the front end region A1 is easily curved toward the topsheet 2 side, and the formation of the recessed portion S is facilitated. In addition, it becomes easier to form a cup-shaped structure integrally formed by the hollow portion S and the pair of three-dimensional gathers 10 and 10 located on the left and right sides thereof, and the fit and leakage resistance are further improved. To do. Temporarily, when the linear recessed part 21 is extended in the vertical direction X or the horizontal direction Y, the bending induction effect of the front end side area | region A1 by such a recessed part 21 is hard to express. Further, as another advantage that the linear concave portions 21 are formed in a lattice shape on the skin facing surface 2a of the top sheet 2, a case where such a lattice pattern is not formed on the skin facing surface 2a at all. Compared to the above, it is easy to visually confirm the shape of the depression S and the formation of the cup-like structure.

本実施形態のナプキン１は、この種の生理用ナプキンと同様に、使用前においては、縦方向Ｘに折り畳まれて個装体とされる。ナプキン１においては、前述したように、横溝５２が横方向Ｙに延びる可撓軸として機能するため、横溝５２を通って横方向Ｙに延びる第１折曲線Ｌ１にて、ナプキン１（本体５）を縦方向Ｘに容易に折り曲げることができる。また、ナプキン１においては、排泄部対向中高領域４１（前側上層吸収体４６）の縦方向後端４１ｂよりも縦方向後側、特に、排泄部対向中高領域４１と後方中高領域４２（後側上層吸収体４７）とに挟まれた領域は、該領域の縦方向Ｘの前後に比して剛性が低いため、該領域を通って横方向Ｙに延びる仮想直線は、横方向Ｙに延びる可撓軸として機能し、従って、ナプキン１（本体５）は、第１折曲線Ｌ１に加えて、該仮想直線に一致する第２折曲線Ｌ２（図１参照）においても、縦方向Ｘに容易に折り曲げることができる。本実施形態における第２折曲線Ｌ２は、図１に示すように、排泄部対向中高領域４１と後方中高領域４２との間に形成された湾曲溝５３の縦方向Ｘの後端を通って横方向Ｙに延びている。   Like the sanitary napkin of this type, the napkin 1 of the present embodiment is folded in the vertical direction X before use to form an individual body. In the napkin 1, since the horizontal groove 52 functions as a flexible shaft extending in the horizontal direction Y as described above, the napkin 1 (main body 5) is taken along the first folding line L1 extending in the horizontal direction Y through the horizontal groove 52. Can be easily folded in the longitudinal direction X. Further, in the napkin 1, the excretory part facing middle / high area 41 and the rear middle / high area 41 (rear upper layer) are arranged at the rear side in the longitudinal direction from the rear end 41b of the excretion part facing middle / high area 41 (front upper layer absorbent body 46). Since the region sandwiched between the absorbers 47) has lower rigidity than before and after the longitudinal direction X of the region, the imaginary straight line extending in the lateral direction Y through the region is flexible in the lateral direction Y. Therefore, the napkin 1 (main body 5) is easily bent in the longitudinal direction X not only at the first folding line L1 but also at the second folding line L2 (see FIG. 1) that coincides with the virtual straight line. be able to. As shown in FIG. 1, the second folding line L <b> 2 in this embodiment passes through the rear end of the longitudinal direction X of the curved groove 53 formed between the excretory portion facing middle and high regions 41 and the rear middle and high regions 42.
