Description
本発明は、生理用ナプキン、パンティライナー（おりものシート）、失禁パッド等の吸収性物品に関する。 The present invention relates to an absorbent article such as a sanitary napkin, a panty liner (cage sheet), and an incontinence pad.
生理用ナプキン等の吸収性物品において、吸収量増加やフィット性改善等による防漏性の向上のため、吸収体の中央部（股下部）を、他の部分よりも厚くしたり、肌当接面側に突出させることが知られている。 In absorbent articles such as sanitary napkins, the center of the absorbent body (in the crotch) is made thicker than other parts, or the skin contacts, in order to improve leakage resistance by increasing absorption or improving fit It is known to project to the surface side.
例えば、特許文献１には、下部吸収材と、前端部域から中央部域の幅方向両端部を内方へ折込み、この折込み部を該下部吸収材の幅よりも狭く形成した上部吸収材とから形成される吸収体を具備し、幅方向中央部域を厚層に且つ後端部域を薄層に形成した生理用ナプキンが提案されている。
尚、特許文献１及び２には、吸収性物品の長手方向両側部に溝や線状の模様を形成した吸収性物品が記載されている。
For example, Patent Document 1 includes a lower absorbent material, and an upper absorbent material formed by folding inward both ends in the width direction from the front end region to the central region, and forming the folded portion narrower than the width of the lower absorbent material. There has been proposed a sanitary napkin comprising an absorbent body formed from the above, in which a central region in the width direction is formed in a thick layer and a rear end region is formed in a thin layer.
Patent Documents 1 and 2 describe absorbent articles in which grooves and linear patterns are formed on both sides in the longitudinal direction of the absorbent article.
特許文献１に開示されているような、従来のナプキンはその肌当接面側に、ナプキンの着用時において、前記中央部と、厚層には形成されていない部分との境界部分に、吸収体の剛性差に起因する皺が入りやすく、このため、該境界部分及びその近傍に位置するナプキンの肌当接面と、着用者の肌との間に隙間が形成されやすく、該隙間に経血等の排泄物が滞留し、滞留した排泄物が、就寝時等において、外部に漏れ出すおそれがある。また、皺や、着用者との間の隙間によって装着感が低下することもある。 As disclosed in Patent Document 1, the conventional napkin absorbs the skin contact surface side at the boundary between the central portion and the portion not formed in the thick layer when the napkin is worn. It is easy for wrinkles due to body rigidity differences to occur, and therefore, a gap is easily formed between the skin contact surface of the napkin located in the boundary portion and the vicinity thereof, and the skin of the wearer. There is a risk that excreta such as blood will stay and the excreta that stays may leak to the outside at bedtime or the like. Moreover, a feeling of wearing may be lowered by a gap between the bag and the wearer.
従って、本発明の目的は、着用時に、吸収体の多層部又は厚層部と他の部分との剛性差に起因する皺が生じにくく、着用者の身体形状に対するフィット性及び防漏性に優れた吸収性物品を提供することにある。 Therefore, the object of the present invention is to prevent wrinkles due to the difference in rigidity between the multilayer portion or the thick layer portion of the absorbent body and other portions during wearing, and is excellent in fit and leakage resistance to the wearer's body shape. It is to provide an absorbent article.
本発明は、着用時の前後方向と同方向に長い吸収体を具備する吸収性物品において、前記吸収体は、長手方向の一部に、他の部分より層数が多い多層部又は他の部分よりも厚い厚層部を有しており、前記吸収体を、前記多層部又は前記厚層部の後端位置において幅方向に横切る仮想直線を想定したときに、前記吸収体の両側部それぞれに、前記仮想直線の前後に亘り且つ該仮想直線から後方に１５ｍｍ以上延びる溝が形成されており、前記吸収性物品を前方から後方に向かって見たときに、該吸収体の両側部に形成された溝の本数が、前記仮想直線と、該仮想直線から１５ｍｍ後方の位置との間で増加していないことを特徴とする吸収性物品を提供することにより前記目的を達成したものである。 The present invention relates to an absorbent article comprising an absorbent body that is long in the same direction as the front-rear direction when worn, wherein the absorbent body is a multilayer part or other part having a larger number of layers than other parts in a part of the longitudinal direction. A thicker layer part thicker than the absorber, assuming an imaginary straight line that crosses the absorber in the width direction at the rear end position of the multilayer part or the thick layer part. In addition, a groove extending 15 mm or more behind the imaginary straight line and extending rearward and rearward from the imaginary straight line is formed, and formed on both sides of the absorbent body when the absorbent article is viewed from the front to the rear. The object is achieved by providing an absorbent article characterized in that the number of grooves is not increased between the virtual straight line and a position 15 mm behind the virtual straight line.
本発明の吸収性物品は、着用時に、吸収体の多層部又は厚層部と他の部分との剛性差に起因する皺が生じにくく、着用者の身体形状に対するフィット性及び防漏性に優れている。 The absorbent article of the present invention is less likely to cause wrinkles due to a difference in rigidity between the multilayer portion or thick layer portion of the absorbent body and other portions when worn, and is excellent in fit and leakage resistance to the wearer's body shape. ing.

The back sheet 3 covers the entire area of the absorbent body 4 on the non-skin contact surface side, and has portions extending outward from both side edges of the absorbent body 4 in the napkin width direction. Side flaps 6 are formed on both side portions in the width direction of the napkin 1 together with the side sheets 5. The side flaps 6 largely extend outward in each of the excretory part facing part A and the rear part C to form a pair of wing parts 61 and 61 and a pair of rear flaps 62 and 62. The rear flap 62 is disposed on the inner surface (skin facing surface) of clothing such as shorts when worn.
Adhesives are respectively applied to the widthwise center portion of the back sheet 3 and the non-skin contact surface side of the pair of wing portions 61, 61 to fix the napkin 1 to shorts or the like (not shown). ) Is formed.
本実施形態のナプキン１における吸収体４は、図１に示すように、着用時の前後方向と同方向に長い形状を有しており、その長手方向の一部に、他の部分より層数が多い多層部Ｍを有している。図１中の点線の斜線部が、多層部Ｍである。多層部Ｍは、吸収体４の幅方向においても、吸収体の一部（具体的には、中央部）に形成されている。
吸収体４は、図１及び図２に示すように、前方部Ｂから後方部Ｃに亘って配された主吸収体４１と、排泄部対向部Ａ付近のみに配された補助吸収体４２とから構成されている。
As shown in FIG. 1, the absorbent body 4 in the napkin 1 of the present embodiment has a shape that is long in the same direction as the front-rear direction at the time of wearing. The multi-layered part M is often included. A hatched portion with dotted lines in FIG. The multilayer part M is also formed in a part (specifically, the central part) of the absorber also in the width direction of the absorber 4.
As shown in FIGS. 1 and 2, the absorbent body 4 includes a main absorbent body 41 disposed from the front part B to the rear part C, and an auxiliary absorbent body 42 disposed only in the vicinity of the excretory part facing part A. It is composed of
主吸収体４１は、図２に示すように、下部吸収体４１１と、該下部吸収体４１１の肌当接面側に配された上部吸収体４１２とから構成されている。下部吸収体４１１及び上部吸収体４１２は、何れも、実質的に縦長の矩形状の平面視形状をなしている。 As shown in FIG. 2, the main absorbent body 41 is composed of a lower absorbent body 411 and an upper absorbent body 412 disposed on the skin contact surface side of the lower absorbent body 411. Each of the lower absorbent body 411 and the upper absorbent body 412 has a substantially vertically long rectangular plan view shape.
補助吸収体４２は、図１及び図２に示すように、主吸収体４１より小型の吸収体で、縦長に形成されており、排泄部対向部Ａにおける下部吸収体４１１と上部吸収体４１２との間に配されている。
主吸収体４１の一部に補助吸収体４２を配することで、吸収体４の一部の吸収容量を容易且つ効率的に増大させることができる。
また、補助吸収体４２が、下部吸収体４１１と上部吸収体４１２との間に挟まれていると、補助吸収体４２が介在している部分とそれより外側の部分との境目付近に段差が大きくならず、厚み方向における重心が略中心付近となるため、ヨレが生じにくくなる。
As shown in FIGS. 1 and 2, the auxiliary absorbent body 42 is a smaller absorbent body than the main absorbent body 41 and is formed in a vertically long shape. The lower absorbent body 411 and the upper absorbent body 412 in the excretory part facing part A It is arranged between.
By arranging the auxiliary absorber 42 in a part of the main absorber 41, the absorption capacity of a part of the absorber 4 can be increased easily and efficiently.
Further, when the auxiliary absorber 42 is sandwiched between the lower absorber 411 and the upper absorber 412, there is a step near the boundary between the portion where the auxiliary absorber 42 is interposed and the portion outside it. It does not increase and the center of gravity in the thickness direction is approximately near the center, so that twisting is less likely to occur.
補助吸収体４２は、図２に示すように、一枚の吸収性シートを折り畳んで形成されている。具体的には、平面視長方形ないし正方形状の吸収性シートにおける、ナプキンの長手方向と一致する方向の両側部を、裏面シート３側に折り返し、その折り返した部分の端縁同士を吸収性シートの幅方向中央部で重ね合わせてある。 As shown in FIG. 2, the auxiliary absorbent body 42 is formed by folding a single absorbent sheet. Specifically, in the absorbent sheet having a rectangular or square shape in a plan view, both side portions in a direction that coincides with the longitudinal direction of the napkin are folded back to the back sheet 3 side, and the edges of the folded portions of the absorbent sheet are joined together. Overlaid at the center in the width direction.
この吸収体４においては、下部吸収体４１１と上部吸収体４１２との間に補助吸収体４２が介在していない部位が２層構造となっているのに対して、下部吸収体４１１と上部吸収体４１２との間に補助吸収体４２が介在する部位が４層構造となっており、補助吸収体４２が介在する該部位が、多層部Ｍとなっている。尚、下部吸収体４１１と上部吸収体４１２とは、補助吸収体４２が介在していない部位において互いに接合されていてもいなくても良く、補助吸収体４２が介在する部位（多層部）においても、下部吸収体４１１と補助吸収体４２との間及び上部吸収体４１２と補助吸収体４２との間はそれぞれ接合されていてもされていなくても良い。 In this absorber 4, the portion where the auxiliary absorber 42 is not interposed between the lower absorber 411 and the upper absorber 412 has a two-layer structure, whereas the lower absorber 411 and the upper absorber The part where the auxiliary absorber 42 is interposed between the body 412 has a four-layer structure, and the part where the auxiliary absorber 42 is interposed is the multilayer part M. The lower absorbent body 411 and the upper absorbent body 412 may or may not be joined to each other at a portion where the auxiliary absorber 42 is not interposed, and also at a portion (multilayer portion) where the auxiliary absorber 42 is interposed. The lower absorbent body 411 and the auxiliary absorbent body 42 and the upper absorbent body 412 and the auxiliary absorbent body 42 may or may not be joined to each other.
本実施形態における吸収体４においては、その長手方向の両側部それぞれに、図１及び図２に示すように、概ねナプキン１の長手方向に延びるように溝７が形成されている。長手方向の左右それぞれに概ね長手方向に延びるように形成された各溝７は、それらの前後端部において、略円弧状に形成された連結部７Ｃ，７Ｄを介して連結されている。連結部７Ｃ，７Ｄのように、概ねナプキン１の幅方向に延びる部分は、溝７や後述する溝７Ａ，７Ｂの一部に含めない。概ね吸収性物品の長手方向に延びる部分と概ね吸収性物品の幅方向に延びる部分との境界は、ナプキン（吸収性物品）１の長手方向中央線ＣＬ又はその平行線に対して、接線のなす角度θが６０度となる部分Ｓ（図１参照、溝外部線と内部線中間位置で接線を計測）である。各溝７は、吸収体４における多層部Ｍ以外の部分に形成されている。より具体的には、溝７は、吸収体４の多層部Ｍを挟んでその両外側に形成されている。 In the absorbent body 4 in the present embodiment, grooves 7 are formed on both side portions in the longitudinal direction so as to extend substantially in the longitudinal direction of the napkin 1 as shown in FIGS. 1 and 2. The grooves 7 formed so as to extend substantially in the longitudinal direction on the left and right in the longitudinal direction are connected to each other at their front and rear end portions via connecting portions 7C and 7D formed in a substantially arc shape. A portion extending in the width direction of the napkin 1 like the connecting portions 7C and 7D is not included in the groove 7 or a part of grooves 7A and 7B described later. The boundary between the portion extending in the longitudinal direction of the absorbent article and the portion extending in the width direction of the absorbent article is generally tangent to the longitudinal center line CL of the napkin (absorbent article) 1 or its parallel line. This is a portion S where the angle θ is 60 degrees (see FIG. 1, tangent is measured at the intermediate position between the groove outer line and the inner line). Each groove 7 is formed in a portion other than the multi-layer unit M in the absorbent body 4. More specifically, the grooves 7 are formed on both outer sides of the multi-layer portion M of the absorbent body 4.
吸収体４の両側部それぞれに形成された溝７は、図１及び図２に示すように、吸収体４を、多層部Ｍの後端位置Ｍａにおいて幅方向に横切る仮想直線Ｘ−Ｘを想定したとき、それぞれ、該仮想直線Ｘ−Ｘの前後に亘っている。即ち、各溝７は、仮想直線Ｘ−Ｘを、吸収体４の前後方向に横切っている。
本実施形態における各溝７は、仮想直線Ｘ−Ｘを横切る箇所においては、図１及び図２に示すように、２本の溝７Ａ，７Ｂとなっている。そして、それらの溝７Ａ，７Ｂは、それぞれ、該仮想直線Ｘ−Ｘから後方に１５ｍｍ以上延びている。即ち、本実施形態においては、仮想直線Ｘ−Ｘの前後に亘り且つ該仮想直線Ｘ−Ｘから後方に１５ｍｍ以上延びる溝が、吸収体の両側部それぞれに、それぞれ、概ねナプキン（吸収性物品）の長手方向に延びるように複数本形成されている。尚、図１中のＹ―Ｙ線は、仮想直線Ｘ−Ｘから１５ｍｍ離間した位置に想定した第２の仮想直線である。
As shown in FIGS. 1 and 2, the grooves 7 formed on both sides of the absorbent body 4 are assumed to be virtual straight lines XX that cross the absorbent body 4 in the width direction at the rear end position Ma of the multilayer section M. When this is done, they respectively extend before and after the virtual straight line XX. That is, each groove 7 crosses the virtual straight line XX in the front-rear direction of the absorber 4.
Each groove 7 in the present embodiment has two grooves 7A and 7B as shown in FIG. 1 and FIG. 2 at a location crossing the virtual straight line XX. And these groove | channels 7A and 7B are each extended 15 mm or more back from this virtual straight line XX. That is, in the present embodiment, grooves extending about 15 mm or more from the imaginary straight line XX to the front and rear of the imaginary straight line XX are substantially napkins (absorbent articles) on both sides of the absorbent body. A plurality of lines are formed so as to extend in the longitudinal direction. The YY line in FIG. 1 is a second virtual straight line assumed at a position 15 mm away from the virtual straight line XX.
溝７Ａ，７Ｂは、多層部Ｍとその他の部分（特に多層部の後方に位置する部分）との剛性差に起因する皺を防止する観点から、仮想直線Ｘ−Ｘから後方に１５〜１５０ｍｍ延びていることがより好ましい。同様の観点から、溝７Ａ，７Ｂは、仮想直線Ｘ−Ｘから前方に延びる長さＬ１（図３参照）が、少なくとも５ｍｍであることが好ましく、１〜１０ｍｍであることがより好ましい。 The grooves 7A and 7B extend 15 to 150 mm rearward from the virtual straight line XX from the viewpoint of preventing wrinkles due to the difference in rigidity between the multilayer portion M and other portions (particularly the portion located behind the multilayer portion). More preferably. From the same point of view, the length L1 (see FIG. 3) of the grooves 7A and 7B extending forward from the virtual straight line XX is preferably at least 5 mm, and more preferably 1 to 10 mm.
また、本ナプキン１においては、ナプキン（吸収性物品）１を前方から後方に向かって見たときに、吸収体４の両側部それぞれに、概ねナプキン１（吸収性物品）の長手方向に沿って形成された溝の本数が、仮想直線Ｘ−Ｘと、該仮想直線Ｘ−Ｘから１５ｍｍ後方の位置（第２仮想直線Ｙ―Ｙ線の位置）との間（図１中にＰで示す領域内）で増加していない。概ねナプキン１（吸収性物品）の長手方向に沿う溝は、その本数が、仮想直線Ｘ−Ｘより後方の全域において増大していないことが好ましい。 Moreover, in this napkin 1, when the napkin (absorbent article) 1 is viewed from the front to the rear, the both sides of the absorbent body 4 are approximately along the longitudinal direction of the napkin 1 (absorbent article). The number of grooves formed is between the virtual straight line XX and a position 15 mm behind the virtual straight line XX (the position of the second virtual straight line YY) (region indicated by P in FIG. 1) (Inside) not increased. It is preferable that the number of grooves substantially along the longitudinal direction of the napkin 1 (absorbent article) does not increase in the entire region behind the virtual straight line XX.
本実施形態のナプキン１においては、吸収体４の長手方向に一部に多層部Ｍを有している。このような構成は、特に高い吸収能力が必要とされる部位の吸収能力（吸収容量）を、全体の装着感を損なうことなく高めたり、あるいは、着用者の液排泄部に対するフィット性を高めたり、多層部Ｍの形状が安定化することによりヨレを生じにくくすることができる等の利点があるが、その反面、溝７Ａ，７Ｂが設けられていない場合には、剛性の高い多層部Ｍと剛性が相対的に小さい他の部位との間の剛性差により、吸収体４が、多層部Ｍの後端Ｍａ近傍（例えば、図１中にＰで示す領域内）に、吸収体４の折れや皺が生じ易かった。
本実施形態のナプキン１によれば、上述した態様で溝７Ａ，７Ｂを設けることで、吸収体４に多層部Ｍを設けることによる剛性差、ひいてはナプキン長手方向の剛性差を緩和でき、ナプキンの着用者に対するフィット性や防漏性を向上させることができる。
In the napkin 1 of the present embodiment, the absorbent body 4 has a multilayer portion M in part in the longitudinal direction. Such a configuration increases the absorption capacity (absorption capacity) of a site where particularly high absorption capacity is required without impairing the overall wearing feeling, or improves the fit of the wearer to the liquid excretion part. However, when the shape of the multi-layer part M is stabilized, there is an advantage that it is possible to make it difficult to generate a twist, but on the other hand, when the grooves 7A and 7B are not provided, Due to the difference in rigidity with other parts having relatively low rigidity, the absorber 4 is folded near the rear end Ma of the multilayer portion M (for example, in the region indicated by P in FIG. 1). It was easy to get a habit.
According to the napkin 1 of the present embodiment, by providing the grooves 7A and 7B in the above-described manner, the rigidity difference due to the multilayer portion M being provided in the absorbent body 4, and hence the rigidity difference in the longitudinal direction of the napkin can be alleviated. It is possible to improve fit and leakproofness for the wearer.
斯かる効果は、本実施形態のナプキン１のように、仮想直線Ｘ−Ｘの前後に亘り且つ該仮想直線Ｘ−Ｘから後方に１５ｍｍ以上延びる溝が、吸収体４の両側部それぞれに複数本形成されていると一層奏されるので好ましいが、本発明における溝は、吸収性物品の両側部それぞれに一本のみ形成されたものであっても良い。 Such an effect, like the napkin 1 of the present embodiment, has a plurality of grooves extending on the front and rear of the imaginary straight line XX and extending 15 mm or more rearward from the imaginary straight line XX on both sides of the absorber 4. Although it is preferable that it is formed, it is preferable that the groove in the present invention is formed by only one groove on each side of the absorbent article.
また、本実施形態のナプキン１においては、仮想直線Ｘ−Ｘの前後に亘り且つ該仮想直線Ｘ−Ｘから後方に１５ｍｍ以上延びる溝７Ａ，７Ｂの内の一方の溝７Ａは、図１に示すように、ナプキン（吸収性物品）１の後方に向かうにつれて、ナプキン（吸収性物品）の長手方向中央線ＣＬに近づくように傾斜している。本発明の吸収性物品においては、複数本の溝を有する場合の全部若しくは一部の溝、又は単一本の溝を有する場合の該溝が、このような向きに傾斜していることが、吸収体４に多層部Ｍを設けることにより生じる剛性差をより一層緩和できることから、好ましい。
尚、傾斜する溝７Ａは、仮想直線Ｘ−Ｘと交差する点における接線と、ナプキン（吸収性物品）の長手方向中央線ＣＬとのなす角度θ１（図１参照）が、５〜６０度であることが好ましく、１５〜４５度であることがより好ましい。
Moreover, in the napkin 1 of this embodiment, one groove | channel 7A of the groove | channels 7A and 7B which extend 15 mm or more behind this virtual straight line XX back and forth is shown in FIG. Thus, as it goes to the back of napkin (absorbent article) 1, it inclines so that it may approach the longitudinal direction center line CL of a napkin (absorbent article). In the absorbent article of the present invention, all or a part of the groove when having a plurality of grooves, or the groove when having a single groove is inclined in such a direction, This is preferable because the difference in rigidity caused by providing the multilayer portion M in the absorber 4 can be further reduced.
The inclined groove 7A has an angle θ1 (see FIG. 1) between a tangent line at a point intersecting the virtual straight line XX and a longitudinal center line CL of the napkin (absorbent article) of 5 to 60 degrees. It is preferable that the angle is 15 to 45 degrees.
本発明の吸収性物品は、多層部Ｍの後端の位置が、吸収体４の前端から後方に１００ｍｍの位置から２００ｍｍの位置までの範囲内、特に吸収体４の前端から後方に１２０ｍｍの位置から１７０ｍｍの位置までの範囲内にあることが、高い吸収能力及び／又はフィット性を要求される部分に経済的あるいは効率的にそのような性能を付与できる観点、及び本発明の効果がより一層顕著に奏される観点から好ましい。また、同様の観点から、上記ナプキン１のように、装着時に非肌当接面側に折り返されてショーツに固定されるウイング部を有する場合、多層部Ｍの後端Ｍａの位置が、該ウイング部６１の後端位置６１ａより前方に２０ｍｍ離間した位置から該後端位置６１ａより後方に６０ｍｍ離間した位置までの範囲内、特にウイング部６１の後端位置の前方に１０ｍｍ離間した位置から該後端位置６１ａより後方に５０ｍｍ離間した位置までの範囲内にあることが好ましい。 In the absorbent article of the present invention, the position of the rear end of the multilayer part M is within the range from the position of 100 mm to the position of 200 mm behind the front end of the absorbent body 4, particularly the position of 120 mm behind the front end of the absorbent body 4. In view of being able to impart such performance economically or efficiently to a portion requiring high absorption capacity and / or fit, and the effects of the present invention are further improved. It is preferable from the viewpoint of being remarkably played. From the same point of view, in the case of having the wing part that is folded back to the non-skin contact surface side and fixed to the shorts when worn, like the napkin 1, the position of the rear end Ma of the multilayer part M is the wing. In the range from a position 20 mm ahead of the rear end position 61 a of the portion 61 to a position 60 mm rearward of the rear end position 61 a, particularly from a position 10 mm ahead of the rear end position of the wing portion 61 It is preferably within a range up to a position spaced 50 mm behind the end position 61a.
本発明の吸収性物品においては、吸収体４の全長（ナプキン長手方向の長さ）が１７０〜３７０ｍｍの範囲にあることが好ましく、また、吸収体の幅（ナプキン幅方向の長さ）が６０〜９０ｍｍの範囲にあることが好ましい。また、多層部Ｍは、その全長（ナプキン長手方向の長さ）が７０〜２００ｍｍ、幅（ナプキン幅方向の長さ）が３０〜５０ｍｍの範囲にあることが好ましい。吸収体４と多層部Ｍとの全長比は、（吸収体全長）：（多層部全長）＝１：０．１８〜１：０．５４の範囲にあることが好ましく、また、吸収体４と多層部Ｍとの幅比は、（吸収体全幅）：（多層部前幅）＝１：０．３〜１：０．８４の範囲にあることが好ましい。 In the absorbent article of the present invention, the total length of the absorbent body 4 (length in the napkin longitudinal direction) is preferably in the range of 170 to 370 mm, and the width of the absorbent body (length in the napkin width direction) is 60.

The rigidity here is measured as follows.
Using a handometer manufactured by Daiei Kagaku Seiki Seisakusho, which conforms to the stiffness measurement method specified in JIS L1096 (General Textile Testing Method), a test piece is placed on a sample table adjusted to 30 mm between slots. The measurement site of the test piece [the central position of the multilayer portion M of the absorber (the position of the ZZ line in FIG. 1, hereinafter also referred to as the ZZ portion), the XX portion or the YY portion] is the center between the slots. So that the length of the absorber of the test piece coincides with the direction perpendicular to the slot, and the test piece is placed horizontally (not fixed to the sample stage) and 8 mm below the sample stage surface (the lowest position) ) The blade adjusted so as to descend to the maximum value indicated by the indicator (load meter) when the blade is lowered at a constant speed of 200 mm / min from above the specimen and pressed back and forth in the length direction ( cN). The measurement was performed 5 times, and the average value was calculated as the stiffness value.

In addition, the test piece was taken out from the absorbent article so as not to damage the absorbent, and a sample having a width of 75 mm and a length of 270 mm and a semicircular shape at both ends in the longitudinal direction was obtained. In this case, it is preferable to eliminate materials other than the absorber as much as possible, but in order not to damage the absorber, a part of the surface sheet / back surface sheet or a part of the adhesive for joining the surface sheet and the back sheet adhered. It may be in a state. In addition, when the width | variety of a test piece differs, a rigidity value is converted into 75 mm width and adjusted. Further, the measurement is possible if the length is 50 mm (30 mm between slots + 10 mm at both ends) or more (no conversion is necessary).
Also, the thickness of the absorber is the same as the sample for stiffness measurement, but the absorber taken out so as not to break is used, but measured at the part that does not contain materials other than the absorber such as the topsheet, backsheet and adhesive. To do.
The measurement of thickness, using a "PEACOCK UPRIGHT DIAL GUAGE No.207" is the thickness gauge manufactured by Ozaki Seisakusho Co., measured under 2.5 g / cm 2 load. In the measurement, the average value measured for five samples was taken as the thickness.

得られた各吸収体サンプルについて、ハンドロメータを用いて剛性を測定した。
剛性は、各吸収体サンプルについて、多層部Ｍの長手方向中央位置（Ｚ−Ｚ部分）、多層部の後端位置Ｍａ（Ｘ−Ｘ部分）及び後端位置Ｍａより更に１５ｍｍ後方の位置（Ｙ−Ｙ部分）の３カ所における剛性を測定した。具体的には、Ｚ−Ｚ部分、Ｘ−Ｘ部分又はＹ−Ｙ部分を、スロット間の中心にくるように且つ吸収体長さ方向がスロットに直交する方向と一致するようにして、上述した方法により測定した。各吸収体サンプルは、それぞれ１５個以上作成し、各部の剛性値は、５個のサンプルについて同様に測定した平均値を表２に記載した。
(Evaluation)
About each obtained absorber sample, rigidity was measured using the handometer.
The rigidity of each absorber sample is determined by the longitudinal center position (Z-Z portion) of the multilayer part M, the rear end position Ma (XX part) of the multilayer part, and the position 15 mm behind the rear end position Ma (Y The rigidity was measured at three locations (-Y portion). Specifically, the method described above, with the ZZ portion, the XX portion, or the YY portion so as to be in the center between the slots and the length direction of the absorber coincide with the direction orthogonal to the slots. It was measured by. Each absorber sample was prepared in 15 pieces or more, and the rigidity values of each part are shown in Table 2 as average values measured in the same manner for 5 samples.
表２に示す結果から判るように、多層部Ｍの剛性値４０ｃＮ（Ｚ−Ｚ部分）であるのに対し、多層部Ｍの後端位置Ｍａにおいて吸収体４を幅方向に横切る仮想直線Ｘ−Ｘを想定したときに、仮想直線Ｘ−Ｘの前後に亘り且つ該仮想直線Ｘ−Ｘから後方に１５ｍｍ以上延びる溝を形成することにより、多層部Ｍとその後方との間の剛性差を緩和できることが判る。更に、実施例４，５のように、後方に向かうに従って長手方向中央線ＣＬに近づくように傾斜した溝を形成するか、あるいは、実施例７のように、吸収体の両側部それぞれに複数本の溝を形成することにより、そのような効果が一層奏されることが判る。 As can be seen from the results shown in Table 2, while the rigidity value of the multilayer portion M is 40 cN (Z-Z portion), an imaginary straight line X- crossing the absorber 4 in the width direction at the rear end position Ma of the multilayer portion M. When X is assumed, a difference in rigidity between the multilayer portion M and the rear thereof is mitigated by forming a groove extending 15 mm or more behind the virtual straight line XX and extending back and forth from the virtual straight line XX. I understand that I can do it. Further, as in the fourth and fifth embodiments, grooves that are inclined so as to approach the longitudinal center line CL toward the rear are formed, or a plurality of grooves are formed on both sides of the absorber as in the seventh embodiment. It can be seen that such an effect is further achieved by forming the groove.

その結果を表２に示した。実施例１〜７のナプキンは透明なモデルの股間部になだらかに沿った形状であり、装着時の形状安定性に優れ、中央部（多層部Ｍ）及び多層部Ｍの後端位置Ｍａ付近の両方における身体へのフィット性が良好であった。これに対し、比較例１〜４のナプキンは、多層部Ｍの後端位置Ｍａ付近に皺が大きく入った。このため、透明なモデルへのフィット性に劣り、装着形状が悪かった。 The results are shown in Table 2. The napkins of Examples 1 to 7 have a shape that gently follows the crotch portion of the transparent model, and are excellent in shape stability at the time of wearing, in the vicinity of the central portion (multilayer portion M) and the rear end position Ma of the multilayer portion M. The body fit in both was good. In contrast, the napkins of Comparative Examples 1 to 4 had large wrinkles near the rear end position Ma of the multilayer portion M. For this reason, the fit to a transparent model was inferior and the mounting shape was bad.
〔液流れ性の評価〕
得られたナプキンについて、ナプキン装着用のアクリル樹脂製の女性が立っている状態の腰部部分を再現した透明なモデルを用いて該ナプキンを生理用ショーツ（製品名：ロリエアクティブガード（コットンフィール）、Ｌサイズ）を用いて擬似的に装着し、評価台に寝た姿勢（生理用ショーツの側部接合線の角度と評価台とが約２５°の傾き）に置いて股間部から馬脱繊維血液を１０ｇ注入させた時の注入部からの液流れ性を観察した。液流れ評価の判断基準は、◎：滞留しない、○：若干液が滞留する、△：液が滞留し拡散する（皺に沿って拡散）、×：液が滞留／拡散し、吸収体側方を超えて流れでる（後部フラップ６２に液が達する）、とした。
[Evaluation of fluidity]
About the obtained napkin, the sanitary shorts (Product name: Laurier Active Guard (Cotton Feel) L size) and put it in a posture lying down on the evaluation table (the angle of the side joint line of the sanitary shorts and the evaluation table is about 25 ° inclination) and equine defibrinated blood from the crotch The liquid flowability from the injection part when 10 g of was injected was observed. Judgment criteria for liquid flow evaluation are: ◎: not staying, ○: some liquid staying, △: liquid staying and diffusing (diffusing along the ridge), x: liquid staying / diffusing, side of absorber It flowed beyond (the liquid reaches the rear flap 62).
結果を表２に示した。実施例１〜７のナプキンは中央部（多層部Ｍ）及び多層部Ｍの後端位置Ｍａ付近の両方における身体へのフィット性が良好であるため、液流れ性も良好であった。これに対し、比較例１〜４のナプキンは、多層部Ｍの後端位置Ｍａ付近に皺が大きく入り、この皺内に液が滞留し、滞留後、後部に流れでる結果であった。 The results are shown in Table 2. Since the napkins of Examples 1 to 7 had good fit to the body in both the central portion (multilayer portion M) and the vicinity of the rear end position Ma of the multilayer portion M, the liquid flowability was also good. On the other hand, the napkins of Comparative Examples 1 to 4 were the result that the soot entered the vicinity of the rear end position Ma of the multi-layer part M, the liquid stayed in the soot, and flowed to the rear after the stay.
