Description
本発明は、主には生理用ナプキン、おりものシート、失禁パッド、トイレタリー等に使用される吸収性物品であって、詳しくは吸収体の幅方向中央部に肌側に増厚した中高部を備えるとともに、この中高部の両側にそれぞれ吸収性物品の略長手方向に延びる左右対の圧搾溝が形成された吸収性物品に関する。 The present invention is an absorbent article mainly used for sanitary napkins, octopus sheets, incontinence pads, toiletries, etc., and more specifically, the middle and high parts thickened on the skin side at the center in the width direction of the absorbent body. The present invention relates to an absorbent article in which a pair of left and right squeezing grooves extending substantially in the longitudinal direction of the absorbent article are formed on both sides of the middle and high portions.
従来より、パンティライナー、生理用ナプキン、失禁パッドなどの吸収性物品として、ポリエチレンシートまたはポリエチレンシートラミネート不織布などの不透液性裏面シートと、不織布または透液性プラスチックシートなどの透液性表面シートとの間に綿状パルプ等からなる吸収体を介在したものが知られている。 Conventionally, as an absorbent article such as a panty liner, sanitary napkin, incontinence pad, a liquid-impervious back sheet such as a polyethylene sheet or a polyethylene sheet-laminated nonwoven fabric, and a liquid-permeable surface sheet such as a nonwoven fabric or a liquid-permeable plastic sheet There is known an intervening absorber made of cotton-like pulp or the like.
この種の吸収性物品にも幾多の改良が重ねられ、体液漏れを防止するとともに、装着時に身体の形状に沿って吸収性物品を変形しやすくする等のため、肌当接面側から非肌側に向けて窪ませた圧搾溝を種々の形態で形成する技術が存在する。 Numerous improvements have been made to this type of absorbent article to prevent leakage of bodily fluids and to make it easier to deform the absorbent article along the shape of the body when worn. There exists a technique for forming the compressed groove recessed toward the side in various forms.
例えば下記特許文献１では、製品長手方向に沿って延びており、肌当接面側から表面シート及び吸収体を圧搾することによって形成されている一対の第１圧搾溝と、製品長手方向に沿って延びており、前記第１圧搾溝よりも製品幅方向の外側において、肌当接面側から表面シート及び吸収体を圧搾することによって形成されている一対の第２圧搾溝とを有しており、前記一対の第１圧搾溝の製品長手方向における後方端部が離間するように構成されており、吸収体は、前記第２圧搾溝よりも製品幅方向の内側で且つ製品長手方向の中央よりも後方側で、製品長手方向に沿って、周囲の剛性値と比べて低い剛性値を有している低剛性領域を有しており、前記低剛性領域内に、前記一対の第１圧搾溝の製品長手方向における後方端部が配置されている吸収性物品が開示されている。 For example, in the following Patent Document 1, a pair of first pressing grooves that extend along the product longitudinal direction and are formed by pressing the surface sheet and the absorbent body from the skin contact surface side, and along the product longitudinal direction. A pair of second pressing grooves formed by pressing the top sheet and the absorbent body from the skin contact surface side outside the first pressing groove in the product width direction. And the rear ends of the pair of first pressing grooves in the product longitudinal direction are separated from each other, and the absorber is located inside the product width direction and the center in the product longitudinal direction from the second pressing groove. A lower rigidity region having a lower rigidity value than the surrounding rigidity value along the longitudinal direction of the product on the rear side, and the pair of first compressions in the low rigidity region The rear end in the product longitudinal direction of the groove is arranged Absorbent article is disclosed that.
また、体液漏れ防止等の手段の一つとして、吸収体の幅方向中央部に長手方向に沿って肌側に増厚した中高部を形成することにより、体液排出部や臀部溝へのフィット性を向上せしめる技術が知られている。例えば下記特許文献２では、中高部は、着用者の体液排出部を含む領域に設けられた中高前方部と、着用者の臀部溝を含む領域に設けられた中高後方部と、前記中高前方部と中高後方部とを吸収性物品の前後方向に繋ぐ領域に設けられるとともに、両側縁が内方に括れている中高括れ部とからなる吸収性物品が開示されている。 In addition, as one of the means for preventing body fluid leakage, by forming a middle and high part thickened on the skin side along the longitudinal direction at the center part in the width direction of the absorbent body, the fit to body fluid discharge part and buttocks groove Techniques for improving the performance are known. For example, in the following Patent Document 2, the middle-high part includes a middle-high front part provided in a region including a wearer's body fluid discharge part, a middle-high rear part provided in a region including a wearer's buttocks groove, and the middle-high front part. In addition, there is disclosed an absorbent article that is provided in a region that connects the rear part to the middle-high rear part in the front-rear direction of the absorbent article, and that includes a middle-high constricted part in which both side edges are constricted inward.
しかしながら、上記特許文献１に記載の吸収性物品では、第１圧搾溝の後方端部が離間する部分が低剛性領域に設けられているため、装着時に幅方向外側から内側に向けた圧力が作用したとき、前記圧搾溝の離間部において吸収体がよれやすくなり、臀部溝に安定してフィットしないとともに、これにより後漏れが発生するおそれがあった。 However, in the absorbent article described in Patent Document 1, the portion where the rear end portion of the first pressing groove is separated is provided in the low-rigidity region, and therefore pressure applied from the outside in the width direction to the inside acts during mounting. When it did, it became easy to swell an absorber in the separation | spacing part of the said pressing groove, and while it did not fit a collar part groove | channel stably, there existed a possibility that a rear leak might generate | occur | produce.
また、上記特許文献２記載の吸収性物品では、中高後方部の後端を吸収性物品の後方側に向かって漸次幅を狭めた先細形状に形成することによって、臀部溝の奥に入り込みやすくしているが、中高部の両側に圧搾溝を形成した場合、この圧搾溝に幅方向内側に向けた圧力が作用したときの中高吸収体の変形やヨレについては一切考慮されておらず、中高部に対して圧搾溝が適切に配置されない場合には、臀部溝に対するフィット性が低下し、体液の後漏れが生じるとともに、装着時にヨレが生じ、装着感が悪化する問題があった。 Further, in the absorbent article described in Patent Document 2, the rear end of the middle / high rear part is formed into a tapered shape with a gradually narrowing width toward the rear side of the absorbent article, thereby making it easier to enter the depth of the buttock groove. However, when the compressed grooves are formed on both sides of the middle and high parts, the deformation and twisting of the medium and high absorber when pressure toward the inner side in the width direction acts on the compressed grooves is not considered at all. On the other hand, when the squeezing groove is not properly disposed, the fit to the buttock groove is lowered, the body fluid is leaked later, and there is a problem in that the wearing feeling is deteriorated at the time of wearing.
そこで本発明の主たる課題は、臀部溝に対するフィット性を向上させ、体液の後漏れを防止するとともに、装着時のヨレを防止し、装着感を向上させた吸収性物品を提供することにある。 Accordingly, a main problem of the present invention is to provide an absorbent article that improves fit to the buttock groove, prevents back leakage of body fluid, prevents twisting at the time of wearing, and improves a feeling of wearing.
上記課題を解決するために請求項１に係る本発明として、透液性表面シートと不透液性裏面シートとの間に吸収体が介在された吸収性物品において、
前記吸収性物品の幅方向中央部であって、少なくとも体液排出部から臀裂部にかけた範囲に肌側に増厚した吸収体の中高部が備えられるとともに、この中高部の両側にそれぞれ、体液排出部に対応する部位を含む領域から臀部溝に対応する部位を含む領域にかけて、吸収性物品の略長手方向に沿って連続して形成された前側長手方向圧搾溝と、前記前側長手方向圧搾溝の後側に離間して配置されるとともに、臀部溝に対応する部位に、吸収性物品の略長手方向に沿って連続して形成された後側長手方向圧搾溝とを有し、
前記後側長手方向圧搾溝の後端部が左右に離間するとともに、前記後側長手方向圧搾溝の後端より前記中高部の後端が吸収性物品長手方向の後方に位置し、かつ前記後側長手方向圧搾溝の後端の延長線上に前記中高部が存在するように、前記後側長手方向圧搾溝の後端部が幅方向内側に傾斜していることを特徴とする吸収性物品が提供される。
In order to solve the above problems, as the present invention according to claim 1, in an absorbent article in which an absorbent body is interposed between a liquid-permeable top sheet and a liquid-impervious back sheet,
The absorbent article has a middle portion in the width direction, at least in a range from the body fluid discharge portion to the rupture portion, and is provided with a middle and high portion of the absorbent that is thickened on the skin side, and a body fluid on each side of the middle and high portion. A front longitudinal squeezing groove formed continuously along a substantially longitudinal direction of the absorbent article from a region including a part corresponding to the discharge part to a region including a part corresponding to the buttocks groove, and the front longitudinal squeezing groove The rear longitudinal pressing groove formed continuously along the substantially longitudinal direction of the absorbent article at a portion corresponding to the buttocks groove and spaced apart on the rear side,
The rear end portion of the rear longitudinal pressing groove is separated from the left and right, and the rear end of the middle and high portion is located rearward in the longitudinal direction of the absorbent article from the rear end of the rear longitudinal pressing groove , and the rear wherein an extension of the rear end of the side longitudinal compression groove as the domed section is present, the absorbent article the rear end of the rear longitudinal compression groove is characterized in that inclined inward in the width direction is Provided.
上記請求項１記載の発明では、前記中高部の両側にそれぞれ、体液排出部に対応する部位を含む領域から臀部溝に対応する部位を含む領域にかけて、吸収性物品の略長手方向に沿って連続して形成された前側長手方向圧搾溝と、前記前側長手方向圧搾溝の後側に離間して配置されるとともに、臀部溝に対応する部位に、吸収性物品の略長手方向に沿って連続して形成された後側長手方向圧搾溝とを有し、前記後側長手方向圧搾溝の後端部が左右に離間するとともに、前記後側長手方向圧搾溝の後端より中高部の後端が吸収性物品長手方向の後方に位置している。すなわち、後側長手方向圧搾溝後端の離間部から中高部の後端部が後方に突出して設けられている。そして、前記後側長手方向圧搾溝の後端の延長線上に前記中高部が存在するように、後側長手方向圧搾溝の後端部が幅方向内側に傾斜している。このため、装着時に幅方向外側から内側に向けて圧力が作用したとき、本吸収性物品では、後側長手方向圧搾溝の後端部が左右に離間しているため、左右の後側長手方向圧搾溝同士が近づくように離間部の離間幅が狭まるように変形することによって、両側からの圧力を幅方向中央の吸収体に効率良く伝達することができ、幅方向中央部の吸収体が肌側に向けて隆起しやすくなる。また、この左右の後側長手方向圧搾溝同士の離間幅が狭まるように作用する力は、後側長手方向圧搾溝後端の延長線が延びる方向に沿って作用するが、本吸収性物品では、前記後側長手方向圧搾溝後端の延長線上に中高部が存在しているため、両側からの圧力のかかり方が均等でない場合でも、中高部によって高剛性化された領域に後側長手方向圧搾溝後端からの力が作用するので、中央部の吸収体がヨレることなく肌側に隆起して臀部溝にフィットしやすくなる。従って、体液の後漏れが防止できるとともに、装着感が向上する。 In the first aspect of the present invention , the absorbent article is continuous along the substantially longitudinal direction of the absorbent article from the region including the portion corresponding to the body fluid discharge portion to the region including the portion corresponding to the buttocks groove on both sides of the middle-high portion. The front longitudinal compression groove formed and the rear longitudinal compression groove are separated from the rear side of the front longitudinal compression groove, and are continuously provided along the substantially longitudinal direction of the absorbent article at a site corresponding to the buttocks groove. And the rear end of the rear longitudinal compression groove is separated from the left and right, and the rear end of the middle and high part is higher than the rear end of the rear longitudinal compression groove. It is located behind the absorbent article in the longitudinal direction. That is, the rear end portion of the middle and high portions protrudes rearward from the separation portion at the rear end of the rear longitudinal compression groove . And the rear-end part of a rear side longitudinal direction pressing groove inclines in the width direction inner side so that the said middle-high part exists on the extension line of the rear end of the said rear side longitudinal direction pressing groove . Therefore, when the pressure applied from the outside in the width direction toward the inside at the time of mounting, in this absorbent article, the rear end of the rear longitudinal compression groove is spaced horizontally, side longitudinal left and right rear By deforming so that the separation width of the separation portion is narrowed so that the compressed grooves approach each other, the pressure from both sides can be efficiently transmitted to the absorber in the center in the width direction. It tends to be raised toward the side. In addition, the force acting so that the separation width between the left and right rear longitudinal pressing grooves narrows acts along the direction in which the extension line of the rear longitudinal pressing groove rear end extends, but in the present absorbent article Since the middle and high portions are present on the extension line of the rear end of the rear longitudinal direction squeezing groove , even if the pressure applied from both sides is not uniform, the region in the rear longitudinal direction is made highly rigid by the middle and high portions. Since the force from the rear end of the compressed groove acts, the absorbent body in the center portion is raised to the skin side without being twisted, and it becomes easy to fit into the groin groove. Therefore, the back leakage of body fluid can be prevented and the wearing feeling is improved.
請求項２に係る本発明として、前記中高部は、着用者の臀部溝に対応する後方部分が吸収性物品の後方に向けて漸次幅を狭めた先細形状に形成されている請求項１記載の吸収性物品が提供される。 According to a second aspect of the present invention, the middle-high portion is formed in a tapered shape in which a rear portion corresponding to the buttocks groove of the wearer is gradually narrowed toward the rear of the absorbent article.

請求項３に係る本発明として、前記延長線と、この延長線が前記中高部の外形線と交差する点より後方に延びる前記中高部の外形線との成す角度が１００〜１７０°である請求項１、２いずれかに記載の吸収性物品が提供される。 According to a third aspect of the present invention, an angle formed between the extension line and the outline of the middle-high portion extending backward from a point where the extension line intersects the outline of the middle-high portion is 100 to 170 °. Item 12. An absorbent article according to any one of Items 1 and 2 is provided.
上記請求項３記載の発明では、前記延長線と中高部の外形線との成す角度を所定の角度範囲とすることによって、後側長手方向圧搾溝に沿って作用する両側からの圧力を前記中高部で効果的に受け止めることができるようになる。 In the invention of claim 3, by setting the angle formed by the extension line and the outer contour line of the middle-high portion within a predetermined angle range, the pressure from both sides acting along the rear longitudinal squeezing groove is increased. It becomes possible to catch it effectively in the department.
請求項４に係る本発明として、前記後側長手方向圧搾溝の後端部の左右の離間距離は、１２〜３０ｍｍである請求項１〜３いずれかに記載の吸収性物品が提供される。 As this invention which concerns on Claim 4, the left-right separation distance of the rear-end part of the said back side longitudinal direction pressing groove is 12-30 mm, The absorbent article in any one of Claims 1-3 is provided.

上記請求項５記載の発明では、着用者の臀部に対応する部分の前記後側長手方向圧搾溝をその他の部分の圧搾溝より高剛性に形成することによって、幅方向外側から内側に向けた臀部からの圧力を幅方向中央部の吸収体に伝達しやすくなり、幅方向中央部が肌側により高く隆起することによって臀部溝へのフィット性が向上できる。前記後側長手方向圧搾溝を高剛性にするには、溝幅を相対的に大きくする、高圧搾部の面積を大きくする、高圧搾部間の距離を狭めて高圧搾部を高密度にするなどの手段のいずれか又は２以上の組み合わせを採用することができる。 In the invention according to claim 5, the rear longitudinal pressing groove of the portion corresponding to the wearer's buttocks is formed with higher rigidity than the pressing groove of the other portion, so that the flange is directed from the outside in the width direction to the inside. It becomes easy to transmit the pressure from the width direction center part absorber, and the fit property to the buttock groove can be improved by raising the width direction center part higher on the skin side. In order to make the rear longitudinal compression groove highly rigid, relatively increase the groove width, increase the area of the high-pressure portion, narrow the distance between the high-pressure portions, and increase the density of the high-pressure portion. Any of these means or a combination of two or more can be employed.
以上詳説のとおり本発明によれば、臀部溝に対するフィット性が向上でき、体液の漏れが防止できるとともに、装着時のヨレが防止でき、装着感を向上させることができるようになる。 As described above in detail, according to the present invention, it is possible to improve fit to the buttocks groove, prevent leakage of body fluids, prevent twisting at the time of wearing, and improve the feeling of wearing.

[Basic structure of sanitary napkin 1]
The sanitary napkin 1 according to the present invention, as shown in FIGS. 1 to 3, is a liquid-impervious back sheet 2 made of a polyethylene sheet or the like, and menstrual blood, or urine (hereinafter collectively referred to as body fluid). ) And the absorbent body 4 made of cotton-like pulp or synthetic pulp interposed between the two sheets 2 and 3 and both sides of the skin contact surface side. A side non-woven fabric 7 provided over the entire length along the direction, and in the periphery of the absorbent body 4, the liquid-impervious back sheet 2 and the liquid-permeable top sheet 3 at the upper and lower edges. The liquid-impervious back surface whose outer edge portion is joined by a bonding means such as an adhesive such as hot melt, a heat seal, an ultrasonic seal or the like, and that both side edge portions extend laterally from the absorbent body 4. Sheet 2 and side nonwoven fabric 7 Adhesive or heat sealing, such as Ttomeruto, by being bonded by bonding means such as ultrasonic sealing, in which the flap portion where the absorber is not interposed is formed. In the illustrated example, the absorbent body 4 is surrounded by a wrapping sheet 5 made of crepe paper or nonwoven fabric in order to maintain the shape of the absorbent body 4 and improve the diffusibility. It does not have to be provided. Although not shown, a second sheet made of a hydrophilic non-woven fabric having substantially the same shape as the liquid-permeable surface sheet 3 may be disposed adjacent to the non-skin side of the liquid-permeable surface sheet 3. .
以下、さらに前記生理用ナプキン１の構造について詳述すると、
前記不透液性裏面シート２は、ポリエチレン等の少なくとも遮水性を有するシート材が用いられるが、蒸れ防止の観点から透湿性を有するものを用いるのが望ましい。この遮水・透湿性シート材としては、ポリエチレンやポリプロピレン等のオレフィン系樹脂中に無機充填剤を溶融混練してシートを成形した後、一軸または二軸方向に延伸することにより得られる微多孔性シートが好適に用いられる。前記不透液性裏面シート２の非肌側面（外面）にはナプキン長手方向に沿って１または複数条の粘着剤層（図示せず）が形成され、身体への装着時に生理用ナプキン１を下着に固定するようになっている。前記不透液性裏面シート２としては、プラスチックフィルムと不織布とを積層させたポリラミ不織布を用いてもよい。
Hereinafter, the structure of the sanitary napkin 1 will be described in detail.
The liquid-impervious back sheet 2 is made of a sheet material having at least water shielding properties such as polyethylene, but it is desirable to use a material having moisture permeability from the viewpoint of preventing stuffiness. The water- and moisture-permeable sheet material is a microporous material obtained by melting and kneading an inorganic filler in an olefin-based resin such as polyethylene or polypropylene to form a sheet, and then stretching in a uniaxial or biaxial direction. A sheet is preferably used. One or more adhesive layers (not shown) are formed on the non-skin side surface (outer surface) of the liquid-impermeable back sheet 2 along the longitudinal direction of the napkin, and the sanitary napkin 1 is attached to the body when worn on the body. It is designed to be fixed to underwear. As said liquid-impermeable back sheet 2, you may use the polylamination nonwoven fabric which laminated | stacked the plastic film and the nonwoven fabric.
次いで、前記透液性表面シート３は、有孔または無孔の不織布や多孔性プラスチックシートなどが好適に用いられる。不織布を構成する素材繊維としては、ポリエチレンまたはポリプロピレン等のオレフィン系、ポリエステル系、ポリアミド系等の合成繊維の他、レーヨンやキュプラ等の再生繊維、綿等の天然繊維とすることができ、スパンレース法、スパンボンド法、サーマルボンド法、メルトブローン法、ニードルパンチ法等の適宜の加工法によって得られた不織布を用いることができる。これらの加工法の内、スパンレース法は柔軟性、ドレープ性に富む点で優れ、サーマルボンド法は嵩高で圧縮復元性が高い点で優れている。前記透液性表面シート３に多数の透孔を形成した場合には、体液が速やかに吸収されるようになり、ドライタッチ性に優れたものとなる。不織布の繊維は、長繊維または短繊維のいずれでもよいが、好ましくはタオル地の風合いを出すため短繊維を使用するのがよい。また、エンボス処理を容易とするために、比較的低融点のポリエチレンまたはポリプロピレン等のオレフィン系繊維のものを用いるのがよい。また、融点の高い繊維を芯とし融点の低い繊維を鞘とした芯鞘型繊維やサイド−バイ−サイド型繊維、分割型繊維の複合繊維を好適に用いることもできる。 Next, as the liquid-permeable surface sheet 3, a porous or non-porous nonwoven fabric or a porous plastic sheet is preferably used. As the material fibers constituting the nonwoven fabric, in addition to olefins such as polyethylene or polypropylene, polyesters, polyamides, and other synthetic fibers, regenerated fibers such as rayon and cupra, and natural fibers such as cotton can be used. A nonwoven fabric obtained by an appropriate processing method such as a method, a spun bond method, a thermal bond method, a melt blown method, or a needle punch method can be used. Of these processing methods, the spunlace method is excellent in terms of flexibility and drapeability, and the thermal bond method is excellent in terms of bulkiness and high compression recovery. When a large number of through-holes are formed in the liquid-permeable surface sheet 3, body fluid is quickly absorbed, and the dry touch property is excellent. The non-woven fiber may be either a long fiber or a short fiber, but preferably a short fiber is used in order to give a towel texture. In order to facilitate the embossing treatment, it is preferable to use an olefin fiber such as polyethylene or polypropylene having a relatively low melting point. Moreover, a core-sheath fiber, a side-by-side fiber, or a split fiber composite fiber having a fiber having a high melting point as a core and a fiber having a low melting point as a sheath can also be suitably used.
前記不透液性裏面シート２と透液性表面シート３との間に介在される吸収体４は、たとえば綿状パルプと吸水性ポリマーとにより構成されている。前記吸水性ポリマーは吸収体を構成するパルプ中に、例えば粒状粉として混入されている。前記パルプとしては、木材から得られる化学パルプ、溶解パルプ等のセルロース繊維や、レーヨン、アセテート等の人工セルロース繊維からなるものが挙げられ、広葉樹パルプよりは繊維長の長い針葉樹パルプの方が機能および価格の面で好適に使用される。前記吸収体４の目付は、２５０〜６５０ｇ／ｍ２、好ましくは３００〜４００ｇ／ｍ２とするのがよい。 The absorbent body 4 interposed between the liquid-impermeable back sheet 2 and the liquid-permeable surface sheet 3 is composed of, for example, cotton-like pulp and a water-absorbing polymer. The water-absorbing polymer is mixed in the pulp constituting the absorber, for example, as granular powder. Examples of the pulp include chemical fibers obtained from wood, cellulose fibers such as dissolving pulp, and artificial cellulose fibers such as rayon and acetate. It is preferably used in terms of price. The basis weight of the absorber 4 is 250 to 650 g / m 2 , preferably 300 to 400 g / m 2 .
また、前記吸収体４には合成繊維を混合しても良い。前記合成繊維は、例えばポリエチレン又はポリプロピレン等のポリオレフィン系、ポリエチレンテレフタレートやポリブチレンテレフタレート等のポリエステル系、ナイロンなどのポリアミド系、及びこれらの共重合体などを使用することができるし、これら２種を混合したものであってもよい。また、融点の高い繊維を芯とし融点の低い繊維を鞘とした芯鞘型繊維やサイド−バイ−サイド型繊維、分割型繊維などの複合繊維も用いることができる。前記合成繊維は、体液に対する親和性を有するように、疎水性繊維の場合には親水化剤によって表面処理したものを用いるのが望ましい。 The absorbent body 4 may be mixed with synthetic fibers. As the synthetic fiber, for example, polyolefins such as polyethylene or polypropylene, polyesters such as polyethylene terephthalate and polybutylene terephthalate, polyamides such as nylon, and copolymers thereof can be used. It may be a mixture. In addition, a composite fiber such as a core-sheath fiber, a side-by-side fiber, or a split fiber having a fiber having a high melting point as a core and a fiber having a low melting point as a sheath can also be used. In the case of a hydrophobic fiber, it is desirable to use a synthetic fiber that has been surface-treated with a hydrophilizing agent so as to have an affinity for body fluids.
前記吸収体４の肌側面には、肌側に増厚された吸収体の中高部６が形成されている。前記吸収体４及び中高部６は、それぞれ別個に製造した後、組立工程で積層してもよいし、吸収体を立体的に積繊することによって一体的に形成してもよい。また、吸収体４の上段に中高部６を積繊する二段積繊構造としてもよい。この中高部６については後段で詳細に説明する。 On the skin side surface of the absorbent body 4, there are formed middle and high portions 6 of the absorbent body thickened on the skin side. The absorbent body 4 and the middle / high portion 6 may be separately manufactured and then stacked in an assembly process, or may be integrally formed by three-dimensionally stacking the absorbent body. Moreover, it is good also as a two-stage fiber structure which accumulates the middle-high part 6 on the upper stage of the absorber 4. FIG. The middle and high portions 6 will be described in detail later.
前記透液性表面シート３の幅寸法は、図示例では、図２及び図３の横断面図に示されるように、吸収体４の幅よりも若干長めとされ、吸収体４を覆うだけに止まり、それより外方側は前記透液性表面シート３とは別のサイド不織布７、具体的には経血やおりもの等が浸透するのを防止する、あるいは肌触り感を高めるなどの目的に応じて、適宜の撥水処理または親水処理を施した不織布素材を用いて構成されたサイド不織布７が配設されている。かかるサイド不織布７としては、天然繊維、合成繊維または再生繊維などを素材として、適宜の加工法によって形成されたものを使用することができるが、好ましくはゴワ付き感を無くすとともに、ムレを防止するために、坪量を抑えて通気性を持たせた不織布を用いるのがよい。具体的には、坪量を１３〜２３ｇ／ｍ２として作製された不織布を用いるのが望ましく、かつ体液の透過を確実に防止するためにシリコン系、パラフィン系、アルキルクロミッククロリド系撥水剤などをコーティングした撥水処理不織布が好適に使用される。 In the illustrated example, the width dimension of the liquid-permeable surface sheet 3 is slightly longer than the width of the absorbent body 4 so as to cover the absorbent body 4 as shown in the cross-sectional views of FIGS. 2 and 3. For the purpose of preventing the penetration of the side nonwoven fabric 7 different from the liquid-permeable surface sheet 3, specifically menstrual blood or the like, or enhancing the touch feeling Accordingly, a side nonwoven fabric 7 constituted by using a nonwoven fabric material subjected to appropriate water repellent treatment or hydrophilic treatment is disposed. The side nonwoven fabric 7 can be made of natural fiber, synthetic fiber, regenerated fiber, or the like and formed by an appropriate processing method. Preferably, the side nonwoven fabric 7 eliminates the feeling of stickiness and prevents stuffiness. For this reason, it is preferable to use a non-woven fabric with reduced basis weight and air permeability. Specifically, it is desirable to use a nonwoven fabric prepared with a basis weight of 13 to 23 g / m 2 , and silicon-based, paraffin-based, alkylchromic chloride-based water repellents, etc. in order to reliably prevent permeation of body fluids. A water repellent nonwoven fabric coated with is preferably used.
前記サイド不織布７は、図２及び図３に示されるように、幅方向中間部より外側部分を所定の内側位置から不透液性裏面シート２の外縁までの範囲に亘ってホットメルトなどの接着剤によって接着し、これら前記サイド不織布７と不透液性裏面シート２との積層シート部分により吸収体４の両側部に吸収体４が介在しないフラップ部が形成されている。このフラップ部は、ほぼ体液排出部Ｈに相当する吸収体側部位置に左右一対のウイング状フラップＷ、Ｗを形成するとともに、これより臀部側（後部側）位置にヒップホールド用フラップＷＢ、ＷＢを形成してもよい。これらウイング状フラップＷ、Ｗおよびヒップホールド用フラップＷＢ、ＷＢの外面側にはそれぞれ粘着剤層（図示せず）が備えられ、ショーツに対する装着時に、前記ウイング状フラップＷ、Ｗを基端部の折返し線ＲＬ位置にて反対側に折り返し、ショーツのクロッチ部分に巻き付けて止着するとともに、前記ヒップホールド用フラップＷＢをショーツの内面に止着するようになっている。 As shown in FIGS. 2 and 3, the side nonwoven fabric 7 is bonded by hot melt or the like over the range from the predetermined inner position to the outer edge of the liquid-impermeable back sheet 2 from the width direction intermediate portion. The flap part which the absorber 4 does not interpose on the both sides of the absorber 4 by the laminated sheet part of these side nonwoven fabrics 7 and the liquid-impermeable back sheet 2 is formed. The flap portion forms a pair of left and right wing-shaped flaps W, W at the absorber side portion position substantially corresponding to the body fluid discharge portion H, and the hip hold flaps W B , W at the hip side (rear side) position from this. B may be formed. These wing-shaped flaps W, W and hip hold flaps W B, respectively pressure-sensitive adhesive layer on the outer surface side of the W B (not shown) is provided, proximal to the time of mounting with respect to shorts, the wing-shaped flaps W, and W folded on the opposite side at the folding line RL position of parts, as well as fastened is wound around the crotch portion of the panties, so as to fasten the hip hold flaps W B to the inner surface of the shorts.
一方、前記サイド不織布７の内方側部分はほぼ二重に折り返されるとともに、この二重シート内部に、その高さ方向中間部に両端または長手方向の適宜の位置が固定された１又は複数本の、図示例では３本の糸状弾性伸縮部材９、９…が両端または長手方向の適宜の位置が固定された状態で配設されている。この二重シート部分は前後端部では図３に示されるように、外側に１回折り返して積層された状態で吸収体４側に接着されることによって、図２に示されるように、外側に傾斜しながら表面側に起立する直線状の立体ギャザーＢＳ、ＢＳが左右対で形成されている。 On the other hand, the inner side portion of the side nonwoven fabric 7 is folded substantially double, and one or a plurality of both ends or appropriate positions in the longitudinal direction are fixed to the middle portion in the height direction inside the double sheet. In the illustrated example, the three elastic elastic members 9, 9... Are arranged in a state where both ends or appropriate positions in the longitudinal direction are fixed. As shown in FIG. 3, the double sheet portion is bonded to the absorber 4 side in a state of being folded once outward and laminated, as shown in FIG. Straight three-dimensional gathers BS and BS standing on the surface side while inclining are formed in a pair of left and right.
〔中高部〕
本生理用ナプキン１では、図１及び図２に示されるように、前記吸収体４の少なくとも体液排出部Ｈから臀裂部にかけた範囲に、肌側に増厚した吸収体の中高部６が設けられている。前記中高部６は、吸収体４の肌側面に隣接するとともに、吸収体４の幅方向中央部に配置され、吸収体４より幅寸法及び長手寸法が小さく形成されている。前記中高部６の厚みは、厚すぎると剛性が上がり身体への密着性が低下するし、薄すぎると体液排出部Ｈとの密着性が低下するため３〜２５mm、好ましくは５〜１８mmとするのがよい。また、前記中高部６が配置された部分の中高部６と吸収体４との合計目付は、４００〜９００ｇ／ｍ２、特に６００〜８００ｇ／ｍ２とするのがよい。
[Middle and high section]
In this sanitary napkin 1, as shown in FIGS. 1 and 2, the middle height 6 of the absorbent body thickened on the skin side is at least in a range from the body fluid discharge part H to the rupture part of the absorbent body 4. Is provided. The middle-high portion 6 is adjacent to the skin side surface of the absorbent body 4 and is disposed at the center in the width direction of the absorbent body 4, and is formed with a width dimension and a longitudinal dimension smaller than the absorbent body 4. If the thickness of the middle-high part 6 is too thick, the rigidity increases and the adhesion to the body decreases, and if it is too thin, the adhesion to the body fluid discharge part H decreases, so that it is 3 to 25 mm, preferably 5 to 18 mm. It is good. In addition, the total basis weight of the middle and high parts 6 and the absorber 4 where the middle and high parts 6 are arranged is preferably 400 to 900 g / m 2 , particularly 600 to 800 g / m 2 .
前記中高部６は、図１に示されるように、着用者の体液排出部Ｈを含む領域に設けられた中高前方部６Ａと、着用者の臀部溝を含む領域に設けられた中高後方部６Ｂと、前記中高前方部６Ａと中高後方部６Ｂとをナプキン前後方向に繋ぐ領域に設けられるとともに、両側縁が内方に括れている中高括れ部６Ｃとから構成されている。 As shown in FIG. 1, the middle-high portion 6 includes a middle-high front portion 6 </ b> A provided in a region including the wearer's body fluid discharge portion H and a middle-high rear portion 6 </ b> B provided in a region including the wearer's buttocks groove. And a middle and high front part 6A and a middle and rear part 6B are provided in a region connecting the front and rear directions of the napkin, and are composed of a middle and high neck part 6C in which both side edges are bound inward.
前記中高前方部６Ａは、着用者の体液排出部Ｈを含む領域、具体的には体液排出部Ｈより前側及び後側に若干長い領域に形成されている。前記中高前方部６Ａは、ナプキン前後方向に長い縦長に形成され、両側縁がナプキン前後方向に延びる直線で形成されている。また、前端縁は、ナプキン前方に向けて膨出する弧状曲線で形成されている。 The middle-high front portion 6A is formed in a region including the body fluid discharge portion H of the wearer, specifically, a region slightly longer on the front side and the rear side than the body fluid discharge portion H. The middle-high front portion 6A is formed in a vertically long shape in the front / rear direction of the napkin, and both side edges are formed by straight lines extending in the front / rear direction of the napkin. The front edge is formed by an arcuate curve that bulges toward the front of the napkin.
前記中高後方部６Ｂは、着用者の臀部溝を含む領域に形成されている。具体的には、着用者の股下側に臀部溝が開始する位置から後方に、臀部溝を越えた位置、臀部溝の終点位置又は臀部溝の中間位置までの領域に設けられている。 The middle-high rear portion 6B is formed in a region including the wearer's buttocks groove. Specifically, it is provided in the region from the position where the buttocks groove starts on the crotch side of the wearer to the rear, the position beyond the buttocks groove, the end position of the buttocks groove or the intermediate position of the buttocks groove.
前記中高後方部６Ｂは、後方部分がナプキン後方に向けて漸次幅を狭めた先細形状に形成するのが好ましい。これにより、中高後方部６Ｂが臀部溝の奥まで入り込みやすくなり、臀部溝を伝う体液の漏れが防止できるようになる。この先細形状は、図示例では、中高後方部６Ｂの前端（中高括れ部６Ｃとの境界）から開始するようにしているが、中高後方部６Ｂの前端から所定の長さだけ両側縁をナプキン前後方向に延びる直線で形成した後、そこから先細形状が開始するようにしてもよい。 The middle-high rear portion 6B is preferably formed in a tapered shape with a rear portion gradually narrowing toward the rear of the napkin. As a result, the middle / high rear portion 6B can easily enter the depth of the buttocks groove, and the leakage of body fluid that travels through the buttocks groove can be prevented. In the illustrated example, this tapered shape starts from the front end of the middle / high rear portion 6B (boundary with the middle / high constricted portion 6C). After forming with the straight line extended in a direction, you may make it a taper shape start from there.
前記中高括れ部６Ｃは、前記中高前方部６Ａと中高後方部６Ｂとをナプキン前後方向に繋ぐ領域に設けられ、中高括れ部６Ｃの前端は中高前方部６Ａの後端に連続し、中高括れ部６Ｃの後端は中高後方部６Ｂの前端に連続している。前記中高括れ部６Ｃは、両側の外形線が幅方向内側に膨出する湾曲形状で形成するのが好ましい。これにより、着用者の体液排出部Ｈの後端から臀部溝の開始位置にかけての肌面に形成される細かな凹凸にもフィットしやすくなり、肌面との密着性が向上できる。 The middle / high neck portion 6C is provided in a region connecting the middle / high front portion 6A and the middle / high rear portion 6B in the front / rear direction of the napkin, and the front end of the middle / high neck portion 6C is continuous with the rear end of the middle / high front portion 6A The rear end of 6C is continuous with the front end of the middle / high rear portion 6B. The middle and high neck portions 6C are preferably formed in a curved shape in which the outlines on both sides bulge inward in the width direction. Thereby, it becomes easy to fit also to the fine unevenness | corrugation formed in the skin surface from a wearer's bodily fluid discharge part H to the starting position of a buttock groove | channel, and adhesiveness with a skin surface can be improved.
前記中高部６は、少なくともパルプ繊維と合成繊維とを含むとともに、前記パルプ繊維：合成繊維の比率を重量換算で８０〜２０：２０〜８０、好ましくは４０〜６０：６０〜４０で混合したものが望ましい。また、前記中高部６は吸水性ポリマーを含有することができる。前記吸水性ポリマーとしては、たとえばポリアクリル酸塩架橋物、自己架橋したポリアクリル酸塩、アクリル酸エステル−酢酸ビニル共重合体架橋物のケン化物、イソブチレン・無水マレイン酸共重合体架橋物、ポリスルホン酸塩架橋物や、ポリエチレンオキシド、ポリアクリルアミドなどの水膨潤性ポリマーを部分架橋したもの等が挙げられる。これらの内、吸水量、吸水速度に優れるアクリル酸またはアクリル酸塩系のものが好適である。前記吸水性能を有する吸水性ポリマーは製造プロセスにおいて、架橋密度および架橋密度勾配を調整することにより吸水力と吸水速度の調整が可能である。配合量は中高部６が吸収体４側への浸透を促進する必要上、配合量を多くすると所謂ゲルブロッキング現象が起きるため、パルプ繊維及び合成繊維の合計重量に対して重量換算で１〜１０％の割合で配合するのが望ましい。なお、吸水性ポリマー含有率が５０％を超える場合にはパルプ繊維間の絡み合いが無くなり、シート強度が低下し破れや割れ等が発生し易くなるため望ましくない。 The middle-high portion 6 includes at least pulp fibers and synthetic fibers, and the ratio of the pulp fibers: synthetic fibers is 80 to 20:20 to 80, preferably 40 to 60:60 to 40 in terms of weight. Is desirable. Moreover, the said middle-high part 6 can contain a water absorbing polymer. Examples of the water-absorbing polymer include cross-linked polyacrylate, self-crosslinked polyacrylate, saponified acrylate-vinyl acetate copolymer cross-linked, isobutylene / maleic anhydride copolymer cross-linked, polysulfone Examples include cross-linked acid salts, and partially cross-linked water-swellable polymers such as polyethylene oxide and polyacrylamide. Among these, those based on acrylic acid or acrylate that are excellent in water absorption and water absorption speed are preferred. The water-absorbing polymer having the water-absorbing performance can be adjusted in water-absorbing power and water-absorbing speed by adjusting the crosslinking density and the crosslinking density gradient in the production process. Since the so-called gel blocking phenomenon occurs when the blending amount is increased because the middle and high portions 6 need to promote the penetration to the absorbent body 4 side, the blending amount is 1 to 10 in terms of weight with respect to the total weight of the pulp fiber and the synthetic fiber. It is desirable to blend in the ratio of%. In addition, when the water-absorbing polymer content exceeds 50%, the entanglement between the pulp fibers is lost, the sheet strength is lowered, and tearing or cracking is likely to occur.
〔圧搾溝〕
本生理用ナプキン１では、前記中高部６の近傍外側部位置に、肌当接面側（透液性表面シート３の外面側）から非肌側（不透液性裏面シート２側）に向けて窪ませた圧搾溝１０が形成されている。前記圧搾溝１０は、少なくとも体液排出部Ｈに対応する部位を含む領域から臀部溝に対応する部位を含む領域にかけての両側部にそれぞれ形成されている。体液排出部Ｈに対応する部位を含む領域とは、生理用ナプキン１の装着時に着用者の体液排出部Ｈが当接する部位を全て含む幅方向中央領域であり、そのナプキン長手方向の範囲は、両側にウイング状フラップＷが備えられたものでは、概ねこのウイング状フラップＷの長手範囲に相当する。また、臀部溝に対応する部位を含む領域とは、生理用ナプキン１の装着時に着用者の臀部溝の少なくとも一部を含む幅方向中央領域であり、股下側の臀部溝の開始位置から後方に臀部溝の中間位置までの範囲である。
(Pressing groove)
In the sanitary napkin 1, the skin contact surface side (the outer surface side of the liquid-permeable surface sheet 3) is directed from the skin contact surface side (the outer surface side of the liquid-permeable surface sheet 3) toward the non-skin side (the liquid-impermeable back sheet 2 side). A depressed groove 10 is formed. The said compressed groove 10 is formed in the both sides from the area | region containing the site | part corresponding to a buttock groove | channel from the area | region containing the site | part corresponding to the bodily fluid discharge part H at least, respectively. The region including the part corresponding to the body fluid discharge part H is a center region in the width direction including all parts where the wearer's body fluid discharge part H abuts when the sanitary napkin 1 is worn, and the range in the napkin longitudinal direction is In the case where the wing-shaped flaps W are provided on both sides, this generally corresponds to the longitudinal range of the wing-shaped flaps W. Further, the region including the portion corresponding to the buttocks groove is a center region in the width direction including at least a part of the wearer's buttocks groove when the sanitary napkin 1 is worn, and rearward from the start position of the crotch-side buttocks groove. It is the range to the middle position of the buttock groove.
図１に示される生理用ナプキン１において、前記圧搾溝１０は、体液排出部Ｈに対応する部位を含む領域から臀部溝に対応する部位を含む領域にかけての両側部にそれぞれ、ナプキン１のほぼ長手方向に沿って連続して形成された前側長手方向圧搾溝１１、１１と、この前側長手方向圧搾溝１１の後側に離間して配置されるとともに、臀部溝に対応する部位の両側部にそれぞれ、ナプキン１のほぼ長手方向に沿って連続して形成された後側長手方向圧搾溝１２、１２と、前記前側長手方向圧搾溝１１、１１の前側に離間して配置されるとともに、ナプキン１の長手方向中心線を幅方向に横断し、ナプキン１のほぼ幅方向に沿って形成された三日月形状からなる前端三日月形圧搾溝１３と、前記後側長手方向圧搾溝１２、１２の後側に離間して配置されるとともに、ナプキン１の長手方向中心線を幅方向に横断し、後方に向けて膨出する湾曲形状からなる後端湾曲形圧搾溝１４とから構成されている。図示例では、前記前側長手方向圧搾溝１１と後側長手方向圧搾溝１２とは離間しているが、前記前側長手方向圧搾溝１１と後側長手方向圧搾溝１２とを連続させた、体液排出部Ｈに対応する部位を含む領域から臀部溝に対応する部位まで連続する長手方向圧搾溝としてもよい。 In the sanitary napkin 1 shown in FIG. 1, the compressed grooves 10 are substantially longitudinal on the both sides of a region including a region corresponding to the body fluid discharge part H to a region including a region corresponding to the buttocks groove. The front longitudinal squeezing grooves 11 and 11 formed continuously along the direction and the rear longitudinal squeezing grooves 11 are arranged separately on the rear side of the front longitudinal squeezing grooves 11 and on both sides of the portion corresponding to the buttocks groove, respectively. The rear longitudinal pressing grooves 12 and 12 formed continuously along the substantially longitudinal direction of the napkin 1 and the front longitudinal pressing grooves 11 and 11 are spaced apart from each other, and the napkin 1 A front-end crescent-shaped pressing groove 13 having a crescent shape formed substantially along the width direction of the napkin 1 and a rear side of the rear-side longitudinal pressing grooves 12, 12, which crosses the longitudinal center line in the width direction. do it With the location, and transverse to the longitudinal center line of the napkin 1 in the width direction, and a rear end curved shaped compressed groove 14 that consists of a curved shape that bulges toward the rear. In the illustrated example, the front longitudinal squeezing groove 11 and the rear longitudinal squeezing groove 12 are separated from each other, but the front longitudinal squeezing groove 11 and the rear longitudinal squeezing groove 12 are made continuous. It is good also as a longitudinal direction pressing groove which continues from the area | region containing the site | part corresponding to the part H to the site | part corresponding to a buttocks groove | channel.
前記前側長手方向圧搾溝１１は、図１に示されるように、少なくとも前記中高前方部６Ａ及び中高括れ部６Ｃの両側に配置されるとともに、後端部が前記中高後方部６Ｂに若干かかる位置まで延在している。 As shown in FIG. 1, the front longitudinal compression groove 11 is disposed at least on both sides of the middle-high front portion 6A and the middle-high constricted portion 6C, and the rear end portion is slightly over the middle-high rear portion 6B. It is extended.
また、前記後側長手方向圧搾溝１２は、図１に示されるように、前記中高後方部６Ｂの両側に配置されている。前記後側長手方向圧搾溝１２は、中高後方部６Ｂのナプキン長手方向長さより短い範囲に配置されている。つまり、後側長手方向圧搾溝１２の前端より中高後方部６Ｂの前端が前側に位置し、後側長手方向圧搾溝１２の後端より中高後方部６Ｂの後端が後側に位置している。 Moreover, the said rear side longitudinal direction pressing groove 12 is arrange | positioned at the both sides of the said middle-high rear part 6B, as FIG. 1 shows. The said rear side longitudinal direction pressing groove 12 is arrange | positioned in the range shorter than the napkin longitudinal direction length of the middle-high rear part 6B. In other words, the front end of the middle / high rear portion 6B is located on the front side from the front end of the rear longitudinal compression groove 12, and the rear end of the middle / high rear portion 6B is located on the rear side from the rear end of the rear longitudinal compression groove 12. .
前記後側長手方向圧搾溝１２は、詳細には図４に示されるように、後端部が左右に離間する離間部１５が設けられるとともに、該後側長手方向圧搾溝１２の後端より前記中高部６の後端がナプキン長手方向の後方に位置し、かつ後側長手方向圧搾溝１２の後端の延長線Ｓ上に前記中高部６が存在するように、後側長手方向圧搾溝１２の後端部が幅方向内側に傾斜している。すなわち、左右の後側長手方向圧搾溝１２、１２の後端の離間部１５から中高部６の後端部が後方に突出するとともに、この後側に突出した中高部６において、後側長手方向圧搾溝１２の後端の延長線Ｓが中高部６の外形線と交差するように配置されている。 As shown in detail in FIG. 4, the rear longitudinal compression groove 12 is provided with a separation portion 15 whose rear end portion is separated to the left and right, and the rear longitudinal compression groove 12 from the rear end of the rear longitudinal compression groove 12. The rear longitudinal squeezing groove 12 is located so that the rear end of the middle high part 6 is located rearward in the napkin longitudinal direction and the middle high part 6 exists on the extension line S of the rear end of the rear longitudinal squeezing groove 12. The rear end portion is inclined inward in the width direction. That is, the rear end portion of the middle-high portion 6 protrudes rearward from the separation portion 15 at the rear end of the left and right rear longitudinal compression grooves 12, 12, and the rear longitudinal direction in the middle-high portion 6 projecting rearward The extension line S at the rear end of the compressed groove 12 is arranged so as to intersect the outline of the middle-high portion 6.
このように構成された生理用ナプキン１の装着状態では、図５に示されるように、脚圧や臀部の圧力などの幅方向外側から内側に向けた圧力が作用することにより、左右の後側長手方向圧搾溝１２、１２同士が近づく方向に力がかかるようになる。このとき、本生理用ナプキン１では、後側長手方向圧搾溝１２、１２の後端部が左右に離間しているため、左右の後側長手方向圧搾溝１２、１２が近づくように離間部１５の離間幅が狭まるように変形することによって、両側からの圧力を幅方向中央の吸収体に効率良く伝達することができるようになり、幅方向中央部の吸収体４及び中高部６が肌側に向けて隆起しやすくなる。また、この幅方向内側に向けた力は、同図５に示されるように、後側長手方向圧搾溝１２の延長線Ｓに沿って延長線Ｓの延びる方向に作用するが、本生理用ナプキン１では、後側長手方向圧搾溝１２の後端の延長線Ｓ上に中高部６が存在しているため、中高部６によって高剛性化された領域に後側長手方向圧搾溝１２の後端からの力が作用するので、中央部の吸収体４がヨレることなく肌側に隆起できるようになる。 In the mounted state of the sanitary napkin 1 configured in this way, as shown in FIG. 5, pressure from the outside in the width direction, such as leg pressure and pressure on the buttocks, acts on the left and right rear sides. A force is applied in the direction in which the longitudinal compressed grooves 12 and 12 approach each other. At this time, in the sanitary napkin 1, since the rear end portions of the rear longitudinal compression grooves 12, 12 are separated from each other in the left and right directions, the separation portion 15 is arranged so that the left and right rear longitudinal compression grooves 12, 12 approach each other. It is possible to efficiently transmit the pressure from both sides to the absorbent body at the center in the width direction, and the absorbent body 4 and the middle and high parts 6 at the center portion in the width direction are connected to the skin side. It tends to be raised toward Further, as shown in FIG. 5, the force directed inward in the width direction acts in the direction in which the extension line S extends along the extension line S of the rear longitudinal compression groove 12, but this sanitary napkin 1, since the middle high portion 6 exists on the extension line S of the rear end of the rear longitudinal pressing groove 12, the rear end of the rear longitudinal pressing groove 12 is located in the region made rigid by the middle high portion 6. Therefore, the absorber 4 in the central part can be raised on the skin side without twisting.
これに対して、図６に示されるように、従来の生理用ナプキンでは、(A)左右の圧搾溝５０、５０の後端部が左右に離間するとともに、圧搾溝５０の後端より中高部５１の後端が前方に位置し、圧搾溝５０の後端の延長線上に中高部が存在しないように構成されたものや、(B)左右の圧搾溝５０、５０の後端同士が中高部５１の後端より後方に離間した位置で連結するように構成されたもの、が一般的であった。このため、同図６(A)の形態では、寝姿勢や寝相などによって左右の臀部からの力のかかり方が異なる場合、圧搾溝５０の延長線上の吸収体が中高部５１によって高剛性化されていないため、この圧搾溝５０の延長線が延びる方向に作用する力の大きさの相違によって、中央部の吸収体が斜めに変形したり、ヨレが生じたりして、臀部溝に対するフィット性が低下し、後漏れが生じたり、違和感を感じたりしていた。 On the other hand, as shown in FIG. 6, in the conventional sanitary napkin, (A) the rear end portions of the left and right pressing grooves 50, 50 are separated from each other left and right, and the middle and high portions are higher than the rear end of the pressing groove 50. The rear end of 51 is located in front, and the middle and high portions are configured such that the middle and high portions do not exist on the extension line of the rear end of the pressing groove 50, or (B) the rear ends of the left and right pressing grooves 50 and 50 are the middle and high portions. In general, it is configured to be connected at a position spaced rearward from the rear end of 51. For this reason, in the form of FIG. 6 (A), the absorber on the extension line of the squeezing groove 50 is made highly rigid by the middle-high portion 51 when the way of applying the force from the left and right buttocks differs depending on the sleeping posture and the sleeping phase. Therefore, due to the difference in the magnitude of the force acting in the direction in which the extension line of the compressed groove 50 extends, the absorber in the central part is deformed obliquely or twisted, resulting in a fit to the buttock groove. It decreased, and after-leakage occurred or it felt uncomfortable.
また、同図６(B)の形態では、左右の圧搾溝５０、５０の後端部が離間せず、幅方向中央で連結しているため、左右の圧搾溝５０の力のかかり方の違いによって中央部の吸収体が斜めに変形するのは防止できるものの、ナプキンの両側から圧力が加わったときに左右の圧搾溝５０、５０同士が近づく変形が生じにくいので、中央部の吸収体の隆起高さが低く、臀部にフィットしにくいという問題があった。 Moreover, in the form of FIG. 6 (B), since the rear end portions of the left and right pressing grooves 50, 50 are not separated and are connected at the center in the width direction, the difference in how the right and left pressing grooves 50 are applied. Can prevent the central absorbent body from being obliquely deformed, but when the pressure is applied from both sides of the napkin, it is difficult for the left and right compressed grooves 50, 50 to approach each other. There was a problem that the height was low and it was difficult to fit in the buttocks.
前記圧搾溝についてより詳細に説明すると、前記後側長手方向圧搾溝１２の後端の延長線Ｓとは、図４に示されるように、後側長手方向圧搾溝１２の後端部の溝幅方向中央部を通る接線を後側長手方向圧搾溝１２の後方に延長した直線である。この延長線Ｓは、ナプキン長手方向の後方に向かってナプキン幅方向の中央側（中高部６側）に傾斜している。 When it demonstrates in detail about the said pressing groove, the extension line S of the rear end of the said rear side longitudinal direction pressing groove 12 is the groove width of the rear end part of the rear side longitudinal direction pressing groove 12, as FIG. 4 shows. It is the straight line which extended the tangent which passes in the direction center part back to the back side longitudinal direction compressed groove 12. The extension line S is inclined toward the center side (middle high portion 6 side) in the napkin width direction toward the rear in the napkin longitudinal direction.
図４に示されるように、前記延長線Ｓと、前記延長線Ｓが中高部６の外形線と交差する点より後方に延びる中高部６の外形線との成す角度αが１００〜１７０°、好ましくは１２０〜１４０°とするのがよい。この角度αが１００°より小さいと延長線Ｓが延びる方向に作用する力の入射角が中高部６の外形線に対して垂直に近くなり、中高部６に局所的に大きな力が作用して中高部６の異常な変形が生じやすくなる。また、前記角度αが１７０°より大きいと、延長線Ｓが延びる方向に作用する力の入射角が中高部６の外形線に対して平行に近くなり、前記力を中高部６で受け止め難く、周辺の吸収体４部分にヨレが発生するようになる。 As shown in FIG. 4, the angle α formed between the extension line S and the outline of the middle-high portion 6 extending rearward from the point where the extension line S intersects the outline of the middle-high portion 6 is 100 to 170 °. Preferably, the angle is 120 to 140 °. If this angle α is smaller than 100 °, the incident angle of the force acting in the direction in which the extension line S extends becomes nearly perpendicular to the outline of the middle-high portion 6, and a large force acts locally on the middle-high portion 6. Abnormal deformation of the mid-high portion 6 is likely to occur. Also, if the angle α is greater than 170 °, the incident angle of the force acting in the direction in which the extension line S extends becomes nearly parallel to the outline of the middle-high portion 6, and it is difficult to receive the force at the middle-high portion 6. A twist occurs in the peripheral absorber 4 portion.
また、前記後側長手方向圧搾溝１２の後端の延長線Ｓは、図４に示されるように、ナプキン長手方向線１６との成す角度βが２０〜７０°とするのが好ましい。この角度範囲で後側長手方向圧搾溝１２の後端部が傾斜することにより、前記延長線Ｓに沿った幅方向中央側への力の伝達が効果的に行われるようになる。 Moreover, it is preferable that the extended line S of the rear end of the said rear side longitudinal direction pressing groove 12 makes 20-70 degrees the angle (beta) which the napkin longitudinal direction line 16 makes, as FIG. 4 shows. By tilting the rear end portion of the rear longitudinal pressing groove 12 in this angular range, transmission of force to the center in the width direction along the extension line S is effectively performed.
前記左右対の後側長手方向圧搾溝１２は、中高部６の両側にそれぞれ形成され、後端部が左右に離間して配置されることにより、これら後端部間に離間部１５が形成されている。前記離間部１５の幅方向中央部には、前記後側長手方向圧搾溝１２から所定の離間距離をあけて、中高部６の後端部がナプキン長手方向に沿って配置されている。 The rear longitudinal compression grooves 12 of the left and right pairs are formed on both sides of the middle-high portion 6, and the rear end portions are spaced apart from each other left and right, thereby forming a separation portion 15 between these rear end portions. ing. A rear end portion of the middle-high portion 6 is disposed along the napkin longitudinal direction at a central portion in the width direction of the separation portion 15 with a predetermined separation distance from the rear longitudinal pressing groove 12.
前記離間部１５のナプキン幅方向の離間距離Ｌは、１２〜３０ｍｍ、好ましくは１５〜２５ｍｍとするのがよい。１２ｍｍより小さいと、この離間部１５に介在する中高部６の幅寸法が小さすぎて、中高部６による中央部の補強効果が得られにくく、中央部のヨレなどが生じやすくなる。また、３０ｍｍより大きいと、左右の圧搾溝１２、１２の間隔が広すぎて、臀部溝に対するフィット性が得られにくいとともに、この広い領域にヨレが発生しやすく装着感が悪化するおそれがある。 The separation distance L in the napkin width direction of the separation portion 15 is 12 to 30 mm, preferably 15 to 25 mm. If it is smaller than 12 mm, the width dimension of the middle-high portion 6 interposed in the spacing portion 15 is too small, and it is difficult to obtain the reinforcing effect of the middle portion by the middle-high portion 6, and the center portion is likely to be twisted. Moreover, when larger than 30 mm, while the space | interval of the left and right pressing grooves 12 and 12 is too wide, it is difficult to obtain fit to the buttocks groove, and twisting is likely to occur in this wide region, and the wearing feeling may be deteriorated.
また、前記後側長手方向圧搾溝１２の後端と中高部６とのナプキン幅方向の離間距離Ｍは、２〜１０ｍｍ、好ましくは４〜８ｍｍとするのがよい。離間距離Ｍが２ｍｍより小さいと、中高部６を臀部溝に入り込ませたときに、圧搾溝１２の硬さを感じやすく、装着感が悪くなる。また、１０ｍｍより大きくした場合には、圧搾溝１２と中高部６との間隔が広くなりすぎ、圧搾溝１２と中高部６との間の中高部６により補強されていない吸収体部分でヨレが生じやすくなる。 Further, the separation distance M in the napkin width direction between the rear end of the rear longitudinal pressing groove 12 and the middle-high portion 6 is 2 to 10 mm, preferably 4 to 8 mm. When the separation distance M is smaller than 2 mm, the hardness of the compressed groove 12 is easily felt when the middle and high portions 6 are inserted into the buttocks groove, and the wearing feeling is deteriorated. Moreover, when larger than 10 mm, the space | interval of the pressing groove 12 and the middle-high part 6 will become too wide, and a twist will be in the absorber part which is not reinforced by the middle-high part 6 between the pressing groove 12 and the middle-high part 6. It tends to occur.
前記中高部６の後端部が後側長手方向圧搾溝１２の後端部より後方に突出する突出長Ｎは、図４に示されるように、５〜１５ｍｍ、特に７〜１２ｍｍとするのが好ましい。前記突出長Ｎが５ｍｍより小さいと、後側長手方向圧搾溝１２の後方に形成される中高部６によって補強された領域が小さく、この領域の剛性を十分に高めることができない。 As shown in FIG. 4, the protruding length N at which the rear end portion of the middle-high portion 6 protrudes rearward from the rear end portion of the rear longitudinal pressing groove 12 is 5 to 15 mm, particularly 7 to 12 mm. preferable. When the protrusion length N is smaller than 5 mm, the region reinforced by the middle-high portion 6 formed behind the rear longitudinal compression groove 12 is small, and the rigidity of this region cannot be sufficiently increased.
前記後側長手方向圧搾溝１２は、体液排出部Ｈを含む部分の両側に配置された前側長手方向圧搾溝１１と比較して高剛性に形成するのが好ましい。これにより、臀部溝部分の幅方向外側から内側に向けた臀部からの圧力を、幅方向中央部の吸収体に伝達しやすくなり、幅方向中央部を肌側により高く隆起させることができ、臀部溝へのフィット性が向上できる。前記後側長手方向圧搾溝１２を高剛性にするには、(1)溝幅を相対的に大きくする、(2)圧搾溝底面の圧搾深さを深くした高圧搾部の面積を相対的に大きくする、(3)隣り合う高圧搾部同士の離間距離を狭めて高密度に配置する手段のいずれか又は２以上の組み合わせとすることができる。 It is preferable to form the said rear side longitudinal direction pressing groove 12 highly rigid compared with the front side longitudinal direction pressing groove 11 arrange | positioned at the both sides of the part containing the bodily fluid discharge part H. FIG. Thereby, it becomes easy to transmit the pressure from the collar part toward the inside from the width direction outside of the collar part groove part to the absorber in the width direction center part, and the width direction center part can be raised higher on the skin side. The fit to the groove can be improved. In order to make the rear longitudinal pressing groove 12 highly rigid, (1) the groove width is relatively increased, and (2) the area of the high-pressure pressing part having a deeper pressing depth at the bottom of the pressing groove is relatively set. (3) It is possible to use either one of means for narrowing the distance between adjacent high-pressure parts and arranging them at high density, or a combination of two or more.
図１に示されるように、前記後側長手方向圧搾溝１２の後端部は、前記後側長手方向圧搾溝１２の後方に配置された前記後端湾曲形圧搾溝１４の前端部より前側若しくはナプキン長手方向にほぼ同等の位置とするのが好ましい。すなわち、前記後側長手方向圧搾溝１２と後端湾曲形圧搾溝１４とはナプキン幅方向に重なり代を有さないように配置するのが好ましい。これにより、後側長手方向圧搾溝１２の後端部分の剛性が前記後端湾曲形圧搾溝１４によって高くなりすぎるのが防止でき、この領域の中央部が肌側に隆起しやすくなる。なお、図１に示される例では、前記中高部６の後端部は、後端湾曲形圧搾溝１４の前端部より後側に位置しているが、後端湾曲形圧搾溝１４の前端部とナプキン長手方向にほぼ同等の位置に配置してもよいし、後端湾曲形圧搾溝１４の前端部より前側に配置してもよい。 As shown in FIG. 1, the rear end portion of the rear longitudinal compression groove 12 is located in front of the front end portion of the rear end curved compression groove 14 disposed behind the rear longitudinal compression groove 12 or It is preferable to make the position substantially equal in the longitudinal direction of the napkin. That is, it is preferable to arrange | position so that the said rear side longitudinal direction pressing groove 12 and the rear end curved pressing groove 14 may have no overlap margin in the napkin width direction. Thereby, it can prevent that the rigidity of the rear-end part of the rear side longitudinal direction pressing groove 12 becomes too high with the said rear-end curved compression groove 14, and it becomes easy to raise the center part of this area | region to the skin side. In the example shown in FIG. 1, the rear end portion of the middle-high portion 6 is located behind the front end portion of the rear end curved compressed groove 14, but the front end portion of the rear end curved compressed groove 14 is used. And may be disposed at substantially the same position in the longitudinal direction of the napkin, or may be disposed on the front side of the front end portion of the rear end curved squeezing groove 14.
以上、後側長手方向圧搾溝１２について説明したが、図１に示されるように、前側長手方向圧搾溝１１の臀部溝に対応する部分の後端部を同様の構成とすることにより、後端部が幅方向内側に傾斜した圧搾溝を、ナプキン長手方向に対して複数段に亘って設けるようにしてもよい。詳細には、前側長手方向圧搾溝１１のうち中高後方部６Ｂの両側に配置された部分の後端部が左右に離間するとともに、前記前側長手方向圧搾溝１１の後端より中高部６の後端が後方に位置し、かつ前側長手方向圧搾溝１１の後端の延長線上に中高部６が存在するように、前側長手方向圧搾溝１１の後端部が幅方向内側に傾斜するようにしてもよい。このとき、前記前側長手方向圧搾溝１１の後端部は、後側長手方向圧搾溝１２の前端部より前側又はナプキン長手方向にほぼ同等の位置に配置するのが好ましい。前側長手方向圧搾溝１１の後端部が後側長手方向圧搾溝１２の前端部より後側に位置するように配置した場合には、前側長手方向圧搾溝１１の後端部と後側長手方向圧搾溝１２の前端部とがナプキン幅方向に重なるようになるため、幅方向外側から内側に向けた圧力が二重の圧搾溝によって中央側に伝達されにくくなり、中央部の肌側への隆起が生じ難くなる。 As mentioned above, although the rear side longitudinal direction pressing groove 12 was demonstrated, as FIG. 1 shows, the rear end part of the part corresponding to the collar part groove | channel of the front side longitudinal direction pressing groove 11 is made into the same structure. You may make it provide the pressing groove which the part inclined in the width direction inner side over several steps with respect to the napkin longitudinal direction. Specifically, the rear end portions of the front longitudinal pressing groove 11 disposed on both sides of the middle / high rear portion 6B are separated from each other left and right, and the rear end of the middle longitudinal portion 6 from the rear end of the front longitudinal pressing groove 11. The rear end portion of the front longitudinal pressing groove 11 is inclined inward in the width direction so that the end is located rearward and the middle-high portion 6 exists on the extended line of the rear end of the front longitudinal pressing groove 11. Also good. At this time, the rear end portion of the front longitudinal pressing groove 11 is preferably disposed at a position substantially equal to the front side or the napkin longitudinal direction from the front end portion of the rear longitudinal pressing groove 12. When it arrange | positions so that the rear-end part of the front side longitudinal direction pressing groove 11 may be located in the back side rather than the front-end part of the rear side longitudinal direction pressing groove 12, the rear-end part and rear side longitudinal direction of the front side longitudinal direction pressing groove 11 Since the front end portion of the compressed groove 12 overlaps with the napkin width direction, the pressure from the outer side in the width direction to the inner side is hardly transmitted to the central side by the double compressed groove, and the bulge toward the skin side of the central portion Is less likely to occur.
