本発明は、経血や排尿を吸収保持する体液吸収性物品、より詳しくは、経血や排尿を誘導するための圧搾条溝を有する体液吸収性物品に関する。  The present invention relates to a body fluid-absorbing article that absorbs and holds menstrual blood and urination, and more particularly to a body fluid-absorbing article having a compressed groove for inducing menstrual blood and urination.

従来、特許文献1及び2のように、液透過性のトップシートと、不透液性のバックシートと、トップシートとバックシートとの間に介在された高吸収性のポリマー粒子を有する吸収層と、その表面に長さ方向へ延びる複数条の圧搾条溝とを含む体液吸収性物品は公知である。
特開2000−83994号公報特開2000−51269号公報
Conventionally, as in Patent Documents 1 and 2, an absorbent layer having a liquid-permeable top sheet, a liquid-impervious back sheet, and highly absorbent polymer particles interposed between the top sheet and the back sheet And the bodily fluid absorptive article containing the multiple compression groove | channel which extends in the length direction on the surface is well-known.
JP 2000-83994 A JP 2000-51269 A

特許文献1の体液吸収性物品では、該物品の両側部において、長さ方向へ延びる一対の圧搾条溝が形成されており、圧搾条溝の下には高吸収性ポリマー粒子を含む高密度の吸液性繊維があり、圧搾条溝に流入した経血を速やかに吸収、拡散して経血の横漏れを防止している。  In the body fluid absorbent article of Patent Document 1, a pair of compressed grooves extending in the length direction is formed on both sides of the article, and a high-density polymer particle containing high-absorbent polymer particles is formed under the compressed grooves. There is a liquid-absorbing fiber that quickly absorbs and diffuses menstrual blood that has flowed into the squeezed grooves to prevent side leakage of menstrual blood.

特許文献2の体液吸収性物品では、該物品の中央部において高吸収性ポリマー粒子を混合したポリマーシートを積層して立体部を形成し、立体部を環状の圧搾条溝で囲むことによって、より立体部の立体感を強調し、該物品のフィット性及び吸収性の向上が図られている。  In the bodily fluid absorbent article of Patent Document 2, a three-dimensional part is formed by laminating polymer sheets mixed with superabsorbent polymer particles in the central part of the article, and the three-dimensional part is surrounded by an annular squeeze groove. The three-dimensional effect of the three-dimensional part is emphasized, and the fit and absorption of the article are improved.

しかし、特許文献1の体液吸収性物品では、圧搾条溝に流入した経血が圧搾条溝の下に位置する高吸収性ポリマー粒子に吸収され、高吸収性ポリマー粒子は膨潤してゲル化し、ブロックを形成する。このとき、膨潤ブロックの形成によって圧搾条溝の形状が崩れて経血が充分に拡散することができなくなったり、また、製造工程において、圧搾するときに、圧搾条溝の下にある高吸収性ポリマー粒子の凹凸により、トップシートが破れて、高吸収性ポリマー粒子が外部へ漏出するおそれがある。  However, in the body fluid absorbent article of Patent Document 1, menstrual blood that has flowed into the compressed groove is absorbed by the highly absorbent polymer particles located under the compressed groove, and the highly absorbent polymer particles swell and gel, Form a block. At this time, the shape of the squeeze groove collapses due to the formation of the swollen block, and menstrual blood cannot be sufficiently diffused. Also, in the manufacturing process, when squeezing, the high absorbency under the squeeze groove Due to the irregularities of the polymer particles, the top sheet may be torn and the highly absorbent polymer particles may leak out.

また、特許文献2の体液吸収性物品では、多量の体液が排泄された場合には、排泄された体液が圧搾条溝を越えて、圧搾条溝の外方に位置する高吸収性ポリマー粒子の存在しない、吸収容量の低い領域に拡散するので、その吸収容量を超えた体液の一部が該領域に吸収されず、体液吸収性物品の外部へ漏れ出るおそれがある。  Moreover, in the bodily fluid absorptive article of patent document 2, when a large amount of bodily fluid is excreted, the excreted bodily fluid passes over the compressed groove, and the superabsorbent polymer particles located outside the compressed groove are Since it diffuses into a region having a low absorption capacity that does not exist, a part of the body fluid that exceeds the absorption capacity may not be absorbed by the region and may leak out of the body fluid absorbent article.

そこで、本発明では、製造時にトップシートが破れて高吸収性ポリマーが外部へ漏れ出るおそれがなく、かつ、圧搾条溝の外方へ拡散した体液を速やかに吸収することのできる体液吸収性物品の提供を課題とする。  Therefore, in the present invention, there is no possibility that the top sheet is torn during production and the superabsorbent polymer leaks to the outside, and the bodily fluid absorbent article that can quickly absorb the bodily fluid diffused outward from the compressed groove. The issue is to provide

前記課題を解決するために、本発明が対象とするのは、上面及び下面と、透液性のトップシートと、不液性のバックシートと、前記トップシートと前記バックシートとの間に介在し、分離する高吸収性ポリマー粒子を有する吸収層と、前記上面から前記下面へ向かって延びる圧搾条溝とを含む体液吸収性物品である。  In order to solve the above-described problems, the present invention is directed to an upper surface and a lower surface, a liquid-permeable top sheet, a liquid-free back sheet, and an interposition between the top sheet and the back sheet. And it is a bodily fluid absorptive article containing the absorption layer which has the superabsorbent polymer particle which isolate | separates, and the pressing groove extending from the said upper surface toward the said lower surface.

この発明の特徴とするところは、前記吸収層の配置された領域が、前記高吸収性ポリマー粒子の存在する分布域と、前記高吸収性ポリマー粒子の存在しない非分布域とに区分され、前記圧搾条溝が前記非分布域に形成されており、前記非分布域が前記圧搾条溝の周縁部から外方へ延在していること、にある。  A feature of the present invention is that the region where the absorption layer is arranged is divided into a distribution region where the superabsorbent polymer particles are present and a non-distribution region where the superabsorbent polymer particles are not present, The compressed groove is formed in the non-distributed area, and the non-distributed area extends outward from the peripheral edge of the compressed groove.

本発明は、前記特徴とする構成のほかに、以下の好ましい実施の形態を含む。
(1)前記圧搾条溝が、前記物品の中央部を囲む連続的または非連続的な略環状の溝から形成され、前記非分布域が前記圧搾条溝の形状に沿うような略環状を有してその周縁部から外方へ延在しており、前記分布域が、前記非分布域に囲まれて、その内側に位置する内側分布域と、前記非分布域の外方に位置する外側分布域とに区分されている。
(2)前記吸収層が、透液性の上部シートと、透液性の下部シートと、前記上下部シート間に分布する前記高吸収性ポリマー粒子とから形成され、前記上下部シートの向かい合う内面どうしが接合手段によって接合されている。
(3)前記接合手段が、ホットメルト接着剤であって、前記上下部シートの前後端部と両側縁部とには、高吸収性ポリマーが分布しておらず、前記高吸収性ポリマー粒子が体液を吸収して膨潤することによって、前記前後端部及び前記両側縁部を除き、前記内側分布域と前記外側分布域における前記接合手段の接合が解除される。
(4)前記吸収層と前記バックシートとの間に、高吸収性のポリマー粒子と親水性繊維とを混合して形成された保液層が配置されている。
(5)前記圧搾条溝が、前記トップシートの上面から前記保液層まで延びている。
The present invention includes the following preferred embodiments in addition to the features described above.
(1) The compressed groove is formed from a continuous or discontinuous substantially annular groove surrounding the center of the article, and the non-distributed area has a substantially annular shape that follows the shape of the compressed groove. The distribution area is surrounded by the non-distribution area, the inner distribution area is located inside the non-distribution area, and the outer side is located outside the non-distribution area. It is divided into distribution areas.
(2) The inner surface of the absorbent layer is formed of a liquid-permeable upper sheet, a liquid-permeable lower sheet, and the superabsorbent polymer particles distributed between the upper and lower sheets, and facing the upper and lower sheets. The two are joined by the joining means.
(3) The joining means is a hot melt adhesive, and the superabsorbent polymer particles are not distributed on the front and rear end portions and both side edges of the upper and lower sheet, and the superabsorbent polymer particles By absorbing the body fluid and swelling, the joining of the joining means in the inner distribution area and the outer distribution area is released except for the front and rear end portions and the side edge portions.
(4) A liquid retaining layer formed by mixing highly absorbent polymer particles and hydrophilic fibers is disposed between the absorbent layer and the back sheet.
(5) The compressed groove extends from the upper surface of the top sheet to the liquid retaining layer.

本発明では、圧搾条溝が、高吸収性ポリマー粒子の存在しない非分布域に形成されているので、製造時に、高吸収性ポリマー粒子の凹凸によってトップシートが破れて高吸収性ポリマーが外部へ漏れ出るおそれはなく、また、高吸収性ポリマー粒子が体液を吸収して膨潤し、ゲル化してブロックを形成しても、圧搾条溝の形状が変形することはなく、経血誘導作用と物品の折曲誘導作用が阻害されるおそれはない。  In the present invention, since the compressed groove is formed in the non-distributed region where the superabsorbent polymer particles do not exist, the topsheet is broken by the unevenness of the superabsorbent polymer particles during production, and the superabsorbent polymer is exposed to the outside. There is no risk of leakage, and even if the superabsorbent polymer particles absorb the body fluid and swell and gel to form a block, the shape of the compressed groove will not be deformed, and the menstrual blood induction effect and article There is no possibility that the bending inducing action is inhibited.

体液吸収性物品の一例として生理用ナプキンを例にとり、添付の図面を参照して本発明の詳細を説明すると、以下のとおりである。  Taking a sanitary napkin as an example of the body fluid absorbent article, the details of the present invention will be described with reference to the accompanying drawings.

図1は、生理用ナプキン10の模式的平面図、図2は、図1のII−II線断面図である。図1では、ナプキン10の縦軸がPで表されている。  FIG. 1 is a schematic plan view of asanitary napkin 10, and FIG. 2 is a cross-sectional view taken along the line II-II in FIG. In FIG. 1, the vertical axis of thenapkin 10 is represented by P.

図1及び2に示すとおり、ナプキン10は、縦長の矩形状を有し、長さ方向及び幅方向と、透液性のトップシート11と、不透液性のバックシート12と、トップシート11とバックシート12との間に介在された吸収層13と、縦軸Pに関して対称の形状を有する圧搾条溝14とを含む。トップシート11とバックシート12とは、吸収層13の周縁から延出する部分で重なり合い、ホットメルト接着剤(図示せず)を介して接合されている。  As shown in FIGS. 1 and 2, thenapkin 10 has a vertically long rectangular shape, a length direction and a width direction, a liquid-permeable top sheet 11, a liquid-impermeable back sheet 12, and atop sheet 11. And anabsorbent layer 13 interposed between theback sheet 12 and apressing groove 14 having a symmetrical shape with respect to the longitudinal axis P. Thetop sheet 11 and theback sheet 12 overlap at a portion extending from the peripheral edge of theabsorbent layer 13 and are joined via a hot melt adhesive (not shown).

吸収層13は、透液性のプラスチックフィルムから形成された上部シート15と、透液性のプラスチックフィルムから形成された下部シート16と、上下部シート15,16に包被された高吸収性ポリマー粒子17とを含む。上下部シート15,16は、接合手段18によって互いに固定され、パッド状またはシート状を有している。上部シート15は、下部シート16よりも幅方向へ僅かに延出し、両シート15,16の接合された両側縁部は、吸収層13の下側において、内方へ向かって折り返されている。  Theabsorbent layer 13 includes anupper sheet 15 formed from a liquid permeable plastic film, alower sheet 16 formed from a liquid permeable plastic film, and a superabsorbent polymer encapsulated in the upper andlower sheets 15, 16.Particles 17. The upper andlower sheets 15 and 16 are fixed to each other by thejoining means 18 and have a pad shape or a sheet shape. Theupper sheet 15 slightly extends in the width direction as compared with thelower sheet 16, and both side edges where both thesheets 15, 16 are joined are folded inward at the lower side of theabsorbent layer 13.

圧搾条溝14は、内方へ僅かに湾曲して長さ方向へ延び、縦軸Pに関して対称であって幅方向へ離間対向する一対の両側溝と、両側溝間において、該両側溝に接続することなく、外方へ凸となり幅方向へ延び、長さ方向へ離間対向する前後端溝とから形成されており、全体として非連続的な略環状を呈している。  Thecompressed groove 14 is slightly curved inward and extends in the length direction, is symmetrical with respect to the longitudinal axis P, and is connected to the both side grooves between a pair of both side grooves that are spaced apart from each other in the width direction. Without forming, it is formed of front and rear end grooves that are convex outward and extend in the width direction and are spaced apart from each other in the length direction, and form a discontinuous substantially annular shape as a whole.

圧搾条溝14は、吸収層13をトップシート11とバックシート12との間に介在させた状態において、後述するように、高吸収性ポリマー粒子17が存在しない部位でトップシート11の上側から熱エンボス加工を施して形成されたものであって、トップシート11と、上部シート15と下部シート16とは圧搾され、周辺よりも密度の高い、厚さ方向へ延びる高密度部位20,21が形成されている。  As will be described later, thecompressed groove 14 is heated from the upper side of thetop sheet 11 in a state where theabsorbent layer 13 is interposed between thetop sheet 11 and theback sheet 12, as will be described later. It is formed by embossing, and thetop sheet 11, theupper sheet 15 and thelower sheet 16 are squeezed to form high-density portions 20 and 21 that are denser than the periphery and extend in the thickness direction. Has been.

図1に示すとおり、圧搾条溝14の周縁部には、圧搾条溝14の形状に沿うように略環状を有する、吸収層13の内部にポリマー粒子17が分布していない第1非分布域23が形成されており、第1非分布域23の内外側には、吸収層13の内部に分離する(いわば、ばらばらに散る状態)高吸収性ポリマー粒子17が存在している分布域が形成されている。具体的には、第1非分布域23に囲まれた、ナプキン10の中心部には内側分布域24が形成されており、第1非分布域23の外方には外側分布域25が形成されている。このように、圧搾条溝14の底部及びその周縁部近傍には、高吸収性ポリマー粒子17が分布していないので、高吸収性ポリマー粒子17が経血を吸収して膨潤したとしても、圧搾条溝14の底面を押し上げたり、圧搾条溝14の形状を変形させたりすることはなく、圧搾条溝14の経血誘導作用とナプキン10の折曲誘導作用とが阻害されることはない。  As shown in FIG. 1, the first non-distributed region in which thepolymer particles 17 are not distributed in theabsorption layer 13 having a substantially annular shape along the shape of thecompressed groove 14 in the peripheral portion of thecompressed groove 14. 23 is formed, and on the inner and outer sides of the firstnon-distributed region 23, a distributed region is formed in which thesuperabsorbent polymer particles 17 that are separated inside the absorbing layer 13 (in other words, scattered in a scattered manner) exist. Has been. Specifically, aninner distribution region 24 is formed at the center of thenapkin 10 surrounded by the firstnon-distribution region 23, and anouter distribution region 25 is formed outside thefirst non-distribution region 23. Has been. Thus, since thesuperabsorbent polymer particles 17 are not distributed near the bottom of thecompressed groove 14 and the peripheral edge thereof, even if thesuperabsorbent polymer particles 17 absorb menstrual blood and swell, they are compressed. The bottom surface of thegroove 14 is not pushed up or the shape of thecompressed groove 14 is not deformed, and the menstrual blood induction action of thecompressed groove 14 and the bending induction action of thenapkin 10 are not inhibited.

すなわち、この種の物品の分野では既に知られているように、圧搾条溝14は、高吸収性ポリマー粒子17が分布して僅かに上方へ隆起している内側分布域24上に排泄されて、内側分布域24から圧搾条溝14に流れて落ちてきた経血をナプキン10の長さ方向へ速やかに移行する経血誘導手段としての役割と、ナプキン10の使用時において、ナプキン10全体を着用者の身体へ向かって僅かに湾曲させて、その中央部に位置する内側分布域24を着用者の身体により密着させるための折曲誘導手段としての役割とを有する。  That is, as already known in the field of this type of article, thecompressed groove 14 is excreted on theinner distribution area 24 where thesuperabsorbent polymer particles 17 are distributed and slightly raised upward. In addition, when thenapkin 10 is used, thenapkin 10 as a whole is used as a menstrual blood guiding means for quickly moving menstrual blood that has flowed down from theinner distribution region 24 to thecompressed groove 14 and moved in the length direction of thenapkin 10. It has a role as a bending guiding means for slightly curving toward the wearer's body and bringing theinner distribution region 24 located at the center thereof into closer contact with the wearer's body.

しかし、高吸収性ポリマー粒子17が圧搾条溝14の底部及びその周縁部近傍に分布している場合には、経血を吸収したポリマー粒子17は膨潤してゲル化し、膨潤ブロックを形成するので、圧搾条溝14を押し上げ、その形状を変形させて、経血の速やかな移行とナプキン10の折り曲げとを妨げるおそれがある。  However, when thesuperabsorbent polymer particles 17 are distributed near the bottom of thecompressed groove 14 and the periphery thereof, thepolymer particles 17 that have absorbed menstrual blood swell and gel, forming a swollen block. There is a possibility that thecompressed groove 14 is pushed up and its shape is deformed to prevent rapid transition of menstrual blood and bending of thenapkin 10.

特に、本物品を吸尿パッド等に用いた場合には、多量の体液の吸収を要するので、吸収層13の内部により多くの高吸収性ポリマー粒子17を散布する必要があるが、その場合には、圧搾条溝14の底部に高吸収性ポリマー粒子17が分布していると、高吸収性ポリマー粒子17による凹凸によって、圧搾工程中に、トップシート11が破れてしまうおそれがある。  In particular, when this article is used for a urine absorption pad or the like, it is necessary to absorb a large amount of body fluid, and thus it is necessary to spray a large amount ofsuperabsorbent polymer particles 17 inside theabsorption layer 13. If thesuperabsorbent polymer particles 17 are distributed at the bottom of thecompressed groove 14, thetopsheet 11 may be broken during the pressing process due to the unevenness of thesuperabsorbent polymer particles 17.

本発明では、圧搾条溝14が高吸収性ポリマー粒子17が分布していない第1非分布域23に形成されているので、高吸収性ポリマー粒子17が経血を吸収して膨潤してゲル化し、膨潤ブロックを形成しても、それによって圧搾条溝14の形状が変形することはなく、経血誘導作用及びナプキン10の折曲作用が妨げられるおそれはない。  In the present invention, since thecompressed groove 14 is formed in the first non-distributedregion 23 where thesuperabsorbent polymer particles 17 are not distributed, thesuperabsorbent polymer particles 17 absorb the menstrual blood and swell to gel. Even if a swelling block is formed, the shape of thecompressed groove 14 is not deformed by this, and there is no possibility that the menstrual blood guiding action and the bending action of thenapkin 10 are hindered.

また、圧搾条溝14の底部に高吸収性ポリマー粒子17が分布していないので、その凹凸によって圧搾時にトップシート11が破れるおそれはなく、さらに、圧搾条溝14の周縁部近傍に高吸収性ポリマー粒子17が存在していないことから、ゲルブロックが圧搾条溝14に流入した経血の浸透、拡散を妨げるおそれもない。  Moreover, since thesuperabsorbent polymer particles 17 are not distributed at the bottom of thecompressed groove 14, there is no possibility that thetop sheet 11 is torn during the compression due to the unevenness, and the superabsorbent is adjacent to the periphery of thecompressed groove 14. Since thepolymer particles 17 are not present, there is no possibility that the gel block will prevent the permeation and diffusion of menstrual blood flowing into thecompressed groove 14.

このような効果を奏するために、第1非分布域23は、圧搾条溝14の周縁から所与寸法外方へ延在している。具体的には、第1非分布域23は、圧搾条溝14の幅寸法よりも、2〜5mmの範囲で外方へ延在していることが好ましい。2mm以下の場合には、ナプキン10の製造工程において、圧搾条溝14を形成する際に、多少のずれが生じて、圧搾条溝14の一部が内側及び外側分布域24,25に形成されるおそれがあり、一方、5mm以上の場合には、第1非分布域23の範囲が比較的に広くなり、ナプキン10全体の吸収性能が低下するおそれがあるからである。  In order to produce such an effect, the first non-distributedregion 23 extends outward from the peripheral edge of thecompressed groove 14 by a given dimension. Specifically, the firstnon-distributed area 23 preferably extends outward in the range of 2 to 5 mm, rather than the width dimension of thecompressed groove 14. In the case of 2 mm or less, when forming thecompressed groove 14 in the manufacturing process of thenapkin 10, some deviation occurs, and a part of thecompressed groove 14 is formed in the inner andouter distribution areas 24 and 25. On the other hand, in the case of 5 mm or more, the range of the firstnon-distributed region 23 becomes relatively wide, and the absorption performance of thewhole napkin 10 may be lowered.

ナプキン10の前後端部には、幅方向へ延びる第2非分布域26と第3非分布域27とがそれぞれ形成されている。このように、ナプキン10の前後端部に第2及び第3非分布域26,27が形成されているので、前後端部を接合するときに、高吸収性ポリマー粒子17による凹凸がなく、トップシート11とバックシート12との接合が容易となるとともに、経血が前後端部にまで拡散されず、経血が前後端部から外部へ漏れ出るおそれもない。また、後述するように、高吸収性ポリマー粒子17が自らの膨潤により、ホットメルト接着剤による接合手段18の接合を解除したとしても、高吸収性ポリマー粒子17が吸収層13から外部へ漏れ出ないようにするために、吸収層13の前後端部と両側縁部とに高吸収性ポリマー粒子17が分布していないことが好ましい。  A secondnon-distributed area 26 and a thirdnon-distributed area 27 extending in the width direction are formed at the front and rear ends of thenapkin 10, respectively. Thus, since the 2nd and 3rd non-distribution area |regions 26 and 27 are formed in the front-and-rear end part of thenapkin 10, when joining the front-and-rear end part, there is no unevenness | corrugation by thesuperabsorbent polymer particle 17, and a top Thesheet 11 and theback sheet 12 can be easily joined, and menstrual blood is not diffused to the front and rear end portions, and there is no possibility that menstrual blood leaks to the outside from the front and rear end portions. Further, as will be described later, even if thesuperabsorbent polymer particles 17 are swollen by themselves and the joining of the joining means 18 by the hot melt adhesive is released, thesuperabsorbent polymer particles 17 leak from theabsorbent layer 13 to the outside. In order to avoid this, it is preferable that thesuperabsorbent polymer particles 17 are not distributed on the front and rear end portions and both side edge portions of theabsorbent layer 13.

高吸収性ポリマー粒子17を被包する上下部シート15,16は、一枚の透液性シートから形成してもよいし、上下部シート15,16の接合端部と接合側縁部とが、内方へ折り返されていてもよい。後者の場合には、これらシート部材のクッション性が増すので、着用感を向上するとともに、体圧がかかっても、吸収層13から経血が外部へ押し出されることはない。  The upper andlower sheets 15 and 16 encapsulating thesuperabsorbent polymer particles 17 may be formed from a single liquid-permeable sheet, and the upper andlower sheets 15 and 16 have bonding end portions and bonding side edge portions. , May be folded inward. In the latter case, the cushioning properties of these sheet members are increased, so that the feeling of wearing is improved and menstrual blood is not pushed out from theabsorbent layer 13 even when body pressure is applied.

上下部シート15,16には、液透過性のシート部材であれば、公知の材料を制限なく用いることができ、例えば、エアスルー不織布、スパンボンド不織布、親水処理された開孔プラスチックフィルム、またはこれらの不織布とプラスチックフィルムを積層してなるラミネートシートから形成することができる。さらに具体的に言えば、ポリエチレンとポリプロピレンからなる芯鞘樹脂繊維をウエブ状にしたエアスルー不織布であって、重量10〜50g/m、厚さ0.3〜0.5mm、繊度1.8〜4.0dtexのものを用いることが好ましい。For the upper andlower sheets 15 and 16, a known material can be used without limitation as long as it is a liquid-permeable sheet member. For example, an air-through nonwoven fabric, a spunbond nonwoven fabric, a hydrophilic treated aperture plastic film, or these It can be formed from a laminate sheet formed by laminating a non-woven fabric and a plastic film. More specifically, it is an air-through nonwoven fabric in which a core-sheath resin fiber made of polyethylene and polypropylene is formed into a web shape, and has a weight of 10 to 50 g / m2 , a thickness of 0.3 to 0.5 mm, and a fineness of 1.8 to It is preferable to use 4.0 dtex.

高吸収性ポリマー粒子17としては、重量が100〜600g/mであって、例えば、澱粉のグラフト重合体、セルロース変性物、水溶性高分子の架橋物、自己架橋型アクリル酸金属塩等、従来、生理用ナプキンや使い捨ておむつ等の吸収性物品の吸収材料として知られている、自己重量の数倍以上の吸水性を有する、公知の水不溶性の高分子ヒドロゲル粒子を用いることができる。高吸収性ポリマー粒子17の重量が100g/m以下の場合には、吸収された経血が逆戻りする(リウエット)おそれがあり、重量が600g/m以上の場合には、高吸収性ポリマー17のゲルブロックが肥大化して、経血の吸収速度が低下するおそれがある。Thesuperabsorbent polymer particles 17 have a weight of 100 to 600 g / m2 and include, for example, a starch graft polymer, a cellulose modified product, a cross-linked product of a water-soluble polymer, a self-crosslinking metal acrylate, and the like. Conventionally known water-insoluble polymer hydrogel particles, which are known as absorbent materials for absorbent articles such as sanitary napkins and disposable diapers, have a water absorption of several times their own weight or more. If the weight of thesuperabsorbent polymer particles 17 is 100 g / m2 or less, the absorbed menstrual blood may be reversed (rewet), and if the weight is 600 g / m2 or more, the superabsorbent polymer There is a possibility that the gel block of 17 is enlarged and the absorption rate of menstrual blood is lowered.

また、下部シート16の内面には、接合手段18を介して上部シート15の内面と固着し易いように、凹凸処理が施されていてもよい。  Further, the inner surface of thelower sheet 16 may be subjected to a concavo-convex treatment so as to be easily fixed to the inner surface of theupper sheet 15 via the joiningmeans 18.

接合手段18には、熱エンボスと、ホットメルト接着剤との両方を用いることができる。  For the joiningmeans 18, both hot embossing and hot melt adhesive can be used.

熱エンボス加工をする場合には、下部シート16の内面に高吸収性ポリマー粒子17を所定の領域に散布し、その内面に上部シート15の内面を重ね合わせて吸収層13を形成した後に、吸収層13の表面にエンボスロールによって熱エンボス加工をする。熱エンボス加工中に高吸収性ポリマー粒子17が第1非分布域23に拡がらないようにするために、高吸収性ポリマー粒子17を下部シート16の内面に散布した後は、上下部シート15,16を速やかに重ね合わせて、平坦なライン上で加工することが好ましい。  In the case of hot embossing, after absorbing thesuperabsorbent polymer particles 17 on the inner surface of thelower sheet 16 in a predetermined region and superposing the inner surface of theupper sheet 15 on the inner surface, theabsorption layer 13 is formed, and then the absorption is performed. The surface of thelayer 13 is hot embossed with an embossing roll. After thesuperabsorbent polymer particles 17 are dispersed on the inner surface of thelower sheet 16 in order to prevent thesuperabsorbent polymer particles 17 from spreading into the firstnon-distributed region 23 during the heat embossing, the upper andlower sheets 15 16 are preferably overlapped quickly and processed on a flat line.

また、エンボスパターンは、多様の形状、寸法を有するものを採用することができるが、一辺が0.5〜5mmの正方形、または直径が0.5〜5mmのドット状のエンボスパターンであって、エンボス部どうしの離間距離が2〜10mmである千鳥状のパターンでなされていることが好ましい。この場合には、エンボス領域が必要以上に硬化したり、フィルム化して液透過性を損なうおそれがなく、かつ、ナプキン10の着用中にナプキン10全体がよれたり揉まれたりしても、接合手段18の接合が解除されて、高吸収性ポリマー粒子17がナプキン10の外部へ漏れ出るおそれはない。  In addition, the embossed pattern may be one having various shapes and dimensions, but is a square with a side of 0.5 to 5 mm, or a dot-like embossed pattern with a diameter of 0.5 to 5 mm, It is preferable that the embossed portions have a staggered pattern in which the distance between the embossed portions is 2 to 10 mm. In this case, there is no possibility that the embossed region is hardened more than necessary, or the liquid permeability is not deteriorated by forming a film, and even if thewhole napkin 10 is twisted or rubbed while thenapkin 10 is worn, the joining means There is no possibility that thesuperabsorbent polymer particles 17 leak out of thenapkin 10 due to the release of the joint 18.

一方、接合手段18としてホットメルト接着剤を塗工する場合には、上部シート15の内面に高吸収性ポリマー粒子17を所定の領域に散布し、下部シート16の内面にホットメルト接着剤を塗工して、下部シート16の内面と上部シート15の内面とを重ね合わせることによって、吸収層13が形成される。  On the other hand, when a hot melt adhesive is applied as the joiningmeans 18, thesuperabsorbent polymer particles 17 are dispersed on a predetermined area on the inner surface of theupper sheet 15 and the hot melt adhesive is applied on the inner surface of thelower sheet 16. Theabsorbent layer 13 is formed by superposing the inner surface of thelower sheet 16 and the inner surface of theupper sheet 15.

ホットメルト接着剤は、コーター、コントロールシーム、スパイラル、サミット式などの各種の塗工方法により、SIS系ホットメルト接着剤、SBS系ホットメルト接着剤、SEBS系ホットメルト接着剤などこの種の物品で一般的に用いられるものを制限なく用いることができる。  Hot melt adhesives can be applied to these types of products such as SIS hot melt adhesives, SBS hot melt adhesives, and SEBS hot melt adhesives by various coating methods such as coater, control seam, spiral, and summit type. Commonly used ones can be used without limitation.

具体的には、コーター塗工による場合には、塗工幅を0.5〜5mm、ピッチを1〜5mm、塗工量を3〜10g/mの範囲にそれぞれ設定して、くし状のパターンで塗工することが好ましい。また、さらに好ましくは、180°の引き剥がし粘着力が0.5N/mm以上であるホットメルト接着剤を用いて、塗工幅を1〜2mm、ピッチを1〜3mm、塗工量を3〜5g/mの範囲に設定して、くし状のパターンでコーター塗工する。この場合には、ナプキン10の製造工程中や包装状態において、不用意に接合手段18の接合が解除されることはなく、かつ、高吸収性ポリマー粒子17が経血を吸収して膨潤したときに、高吸収性ポリマー粒子17が分布されていない吸収層13の前後端部と両側縁部とを除き、外側分布域25と内側分布域24とにおいて接合手段18の接合が解除されるので、高吸収性ポリマー粒子17が上下部シート15,16に押え付けらえることはなく、その吸収性能が阻害されることはない。Specifically, when coater coating is used, the coating width is set to 0.5 to 5 mm, the pitch is set to 1 to 5 mm, and the coating amount is set to the range of 3 to 10 g / m2 . Coating with a pattern is preferred. More preferably, using a hot melt adhesive having a 180 ° peeling adhesive strength of 0.5 N / mm or more, the coating width is 1 to 2 mm, the pitch is 1 to 3 mm, and the coating amount is 3 to 3. Set to a range of 5 g / m2 and coater coat with a comb-like pattern. In this case, when the joining of the joiningmeans 18 is not inadvertently released during the manufacturing process or packaging state of thenapkin 10, and thesuperabsorbent polymer particles 17 swell after absorbing menstrual blood. In addition, since the joining of the joiningmeans 18 is released in theouter distribution area 25 and theinner distribution area 24 except for the front and rear ends and both side edges of theabsorbent layer 13 where thesuperabsorbent polymer particles 17 are not distributed, Thesuperabsorbent polymer particles 17 are not pressed against the upper andlower sheets 15 and 16, and the absorption performance is not hindered.

図3(a),(b)は、本発明の他の実施形態を示す図2と同様の模式的断面図である。ナプキン10の基本的な構成は図2と同様であるので、相違する構成について以下に述べる。  3A and 3B are schematic cross-sectional views similar to FIG. 2 showing another embodiment of the present invention. Since the basic configuration of thenapkin 10 is the same as that in FIG. 2, different configurations will be described below.

図3(a)では、吸収層13とバックシート12との間に、保液層28が形成されている。保液層28は、パルプからなる親水性繊維と高吸収性のポリマー粒子とをティッシュペーパで包被したものであって、これにより、ナプキン10の吸収容量が増大するとともに、吸収速度を向上することができる。具体的には、高吸収性のポリマー粒子(図示せず)と親水性繊維との質量比が3:7〜5:5であることが好ましい。特に、排尿パッドなどの多量の体液の吸収を要する場合には、吸収層13のほかに、複数の吸収層、保液層が配置されていることが好ましい。  In FIG. 3A, aliquid retention layer 28 is formed between theabsorption layer 13 and theback sheet 12. Theliquid retaining layer 28 is obtained by enveloping hydrophilic fibers made of pulp and highly absorbent polymer particles with tissue paper, thereby increasing the absorption capacity of thenapkin 10 and improving the absorption rate. be able to. Specifically, the mass ratio of highly absorbent polymer particles (not shown) and hydrophilic fibers is preferably from 3: 7 to 5: 5. In particular, when it is necessary to absorb a large amount of body fluid such as a urination pad, it is preferable that a plurality of absorption layers and liquid retention layers be arranged in addition to theabsorption layer 13.

また、保液層28の上方には吸収層13が配置しているので、ナプキン10に体圧がかかり、保液層28から経血が押し出されて、トップシート11の側へ浸透する場合であっても、浸透してきた経血は吸収層13に吸収されるので、経血がトップシート11の表面から滲出するおそれはない。  Further, since theabsorbent layer 13 is disposed above theliquid retaining layer 28, body pressure is applied to thenapkin 10, and menstrual blood is pushed out from theliquid retaining layer 28 and penetrates into thetop sheet 11 side. Even if it exists, since the menstrual blood which has penetrated is absorbed by theabsorption layer 13, there is no possibility that menstrual blood will exude from the surface of thetop sheet 11.

図3(b)では、圧搾条溝14が、トップシート11の表面から保液層28まで延びており、トップシート11の一部と、吸収層13の一部と保液層28の一部とが圧搾されて保液層28の内部に、その周辺よりも高密度の高密度部位20,21が形成されている。このように、圧搾条溝14が保液層28にまで延びている場合には、圧搾条溝14に流入してその底面に滞留した経血が保液層28に直接吸収されるので、トップシート11の表面に多量の経血が排泄されたとしても、経血をトップシート11の表面からナプキン10の内部へ速やかに吸収することができる。  In FIG. 3 (b), thecompressed groove 14 extends from the surface of thetop sheet 11 to theliquid retaining layer 28, and a part of thetop sheet 11, a part of theabsorbent layer 13, and a part of theliquid retaining layer 28. And thehigh density portions 20 and 21 having a higher density than the periphery thereof are formed inside theliquid retaining layer 28. As described above, when thecompressed groove 14 extends to theliquid retaining layer 28, menstrual blood that flows into thecompressed groove 14 and stays on the bottom surface thereof is directly absorbed by theliquid retaining layer 28. Even if a large amount of menstrual blood is excreted on the surface of thesheet 11, menstrual blood can be quickly absorbed from the surface of thetop sheet 11 into thenapkin 10.

図4(a)は、第1非分布域23の他の実施の形態を示すナプキン10の平面図であり、図4(b)及び(c)は、圧搾条溝14の他の実施の形態を示すナプキン10の平面図である。  FIG. 4A is a plan view of thenapkin 10 showing another embodiment of the firstnon-distributed area 23, and FIGS. 4B and 4C show other embodiments of thecompressed groove 14. It is a top view of thenapkin 10 which shows.

図4(a)では、第1非分布域23の一部が、圧搾条溝14の両側溝間において、直状を有し、内側分布域24を横断して幅方向へ延びており、長さ方向へ離間対向する一対の横断部位23a,23bを形成している。このように、第1非分布域23は圧搾条溝14の形状とは無関係の形状を有するものであってもよく、ナプキン10全体の吸収性能を考慮して、適宜、第1非分布域23と内側及び外側分布域24,25との範囲を設定することができる。  In FIG. 4A, a part of the firstnon-distributed area 23 has a straight shape between both side grooves of thecompressed groove 14, and extends in the width direction across the inner distributedarea 24. A pair of crossingparts 23a and 23b which are spaced apart in the vertical direction are formed. Thus, the 1stnon-distribution area 23 may have a shape unrelated to the shape of thepressing groove 14, and the 1stnon-distribution area 23 is suitably considered in consideration of the absorption performance of thewhole napkin 10. And inner andouter distribution areas 24 and 25 can be set.

図4(b)では、圧搾条溝14は、長さ方向へ直状に延び、幅方向に離間対向する一対の両側溝から形成されており、図4(b)では、圧搾条溝14は、ナプキン10の中央部を囲む一連の環状の溝から形成されている。圧搾条溝14の形状は、図示された形態に限定されるものではなく、経血をナプキン10の長さ方向へ移行するものである限りにおいては、多様の形状を採用することができる。  In FIG.4 (b), the pressinggroove 14 is formed from a pair of both-sides groove | channel extended in the straight direction at the length direction, and spaced apart and opposed in the width direction. In FIG.4 (b), the pressinggroove 14 is , Formed from a series of annular grooves surrounding the central portion of thenapkin 10. The shape of thecompressed groove 14 is not limited to the illustrated form, and various shapes can be adopted as long as menstrual blood is transferred in the length direction of thenapkin 10.

なお、本発明は、ナプキンのみならず、排尿を吸収、保持する排尿パッド、使い捨ておむつ等の体液吸収性物品に適用することができる。また、各種の体液吸収性物品を構成する材料として、公知の材料を制限なく用いることができる。  The present invention can be applied not only to a napkin but also to a body fluid absorbent article such as a urine pad that absorbs and holds urine and a disposable diaper. Moreover, a well-known material can be used without a restriction | limiting as a material which comprises various body fluid absorptive articles.
