Description
本発明は、生理用ナプキンに関するものである。 The present invention relates to a sanitary napkin.
生理用ナプキン、パンティライナー、おりものシート、失禁パッド等の使い捨て吸収性物品は、表面側に配置された透液性トップシートと裏面側に配置されたバックシートとの間に吸収体が介在された構造が一般的である。この種の吸収性物品において、体液の表面上の拡散を防止する、吸収体にコシをもたせてヨレを防ぐ、吸収体中央部を***させて身体への密着性を高める、等の目的で、トップシートの肌当接面に圧搾溝（エンボス溝）を配する技術が知られている。 Disposable absorbent articles such as sanitary napkins, panty liners, cage sheets, and incontinence pads have an absorber interposed between a liquid-permeable top sheet disposed on the front side and a back sheet disposed on the back side. Structures are common. In this type of absorbent article, for the purpose of preventing diffusion on the surface of bodily fluids, preventing stiffness by giving the absorbent body stiffness, raising the central part of the absorbent body and improving adhesion to the body, etc. A technique for arranging a pressing groove (embossed groove) on the skin contact surface of the top sheet is known.
例えば、特許文献１に開示される吸収性物品においては、圧搾溝は***口当接部の幅方向両側に長手方向に延在するように付与されており、幅方向外側から幅方向中央への力に対して、圧搾溝が更に深く折れることで当該力が吸収され、***口当接部にヨレや変形が生じない構成となっている。 For example, in the absorbent article disclosed in Patent Document 1, the pressing groove is provided so as to extend in the longitudinal direction on both sides in the width direction of the excretory opening contact portion, and from the width direction outer side to the width direction center. The force is absorbed by the deeper squeezing of the squeezing groove with respect to the force, so that the excretion opening contact portion is not twisted or deformed.
生理用ナプキンは、特に昼用の生理用ナプキンにおいては、着用者は生理用ナプキンを装着したまま歩行等の運動をすることが通常である。歩行時においては、脚の動きにより生じる力は、幅方向外側から中央に向かう方向のみでなく、脚の交差時において、斜め前方から斜め後方、及び、斜め後方から斜め前方に生じる。その際、斜め方向にかかる力により、***口当接部分にヨレや変形が生じ、ヨレ等を生じた部分からの***液のモレが生じる恐れがあった。
本発明の課題は、歩行時等においても、***口当接部分にヨレ等の変形を生じず、当該ヨレ等によるモレが防止されるように構成された生理用ナプキンを提供することにある。
In the sanitary napkin, in particular, in the daytime sanitary napkin, the wearer usually moves such as walking while wearing the sanitary napkin. During walking, the force generated by the movement of the legs is generated not only in the direction from the outside in the width direction toward the center, but also from diagonally forward to diagonally backward and from diagonally backward to diagonally forward when the legs cross. At that time, the force applied in the oblique direction may cause a twist or deformation in the excretory opening contact portion, and there is a risk that the excretion of the excretion liquid from the portion where the twist or the like has occurred.
An object of the present invention is to provide a sanitary napkin that is configured such that the excretion opening abutment portion is not deformed even when walking or the like, and that the misregistration is prevented.
次に、上記課題を解決するための手段とそれらの作用効果を示す。

[First Embodiment]
FIG. 1 is a development view showing an example of an embodiment of a sanitary napkin as a sanitary napkin according to this embodiment. 2 is a view taken along line I-I in FIG. 1, FIG. 3 is an enlarged view of a portion II in FIG. 1, and FIG. 4 is an enlarged view of a portion III in FIG. The basic structure of the sanitary napkin 10 is that a liquid-permeable top sheet 1 made of a nonwoven fabric, an absorbent body 3 and a back sheet 2 made of a liquid-impervious sheet such as a polyethylene sheet are laminated in this order, and further, a side nonwoven fabric is formed on the side. 5 and 5 are arranged.
バックシート２としては、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、近年はムレ防止の観点から透湿性を有するものが用いられる傾向にある。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。バックシート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。 As the back sheet 2, a sheet material having at least water shielding properties such as polyethylene is used, but in recent years, a material having moisture permeability tends to be used 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. As the back sheet 2, a polylaminated nonwoven fabric in which a plastic film and a nonwoven fabric are laminated may be used.
透液性トップシート１としては、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ソフトである点で優れている。透液性トップシート１に多数の透孔を形成した場合には、***物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。 As the liquid-permeable top sheet 1, 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. Among these processing methods, the spunlace method is excellent in terms of flexibility and drapeability, and the thermal bond method is excellent in terms of being bulky and soft. When a large number of through holes are formed in the liquid permeable top sheet 1, the excrement is quickly absorbed and the dry touch property is excellent.
トップシート１及びバックシート２は、吸収体３の前後方及び両側方で延出している。この延出部分において、トップシート１及びバックシート２は、ホットメルト等の接着剤やヒートシール等によって接合される。トップシート１及びバックシート２の延出は、前後方向中央部において幅方向に長くし、この長くなった部分で、肌着の裏側（外面側）に折り返されて止着される、いわゆるウィング状フラップＷが構成されている。 The top sheet 1 and the back sheet 2 extend at the front rear side and both sides of the absorber 3. In the extended portion, the top sheet 1 and the back sheet 2 are joined by an adhesive such as hot melt, heat sealing, or the like. The extension of the top sheet 1 and the back sheet 2 is long in the width direction in the central part in the front-rear direction, and is a so-called wing-shaped flap that is folded and fixed to the back side (outer surface side) of the undergarment at this long part. W is configured.
サイド不織布５としては、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ることができる。かかるサイド不織布５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１８〜２３ｇ／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や、パラフィン系等の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。 As the side nonwoven fabric 5, a nonwoven fabric material subjected to appropriate water-repellent treatment or hydrophilic treatment can be used depending on the purpose of preventing menstrual blood or vaginal discharge from penetrating or enhancing touch feeling. . The side nonwoven fabric 5 can be made of natural fibers, synthetic fibers, regenerated fibers or the like and formed by an appropriate processing method. Preferably, the side nonwoven fabric 5 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 18 to 23 g / m 2 , and in order to prevent permeation of body fluids reliably, a silicone-based or paraffin-based water repellent is coated. The water-repellent treated non-woven fabric is preferably used.
トップシート１と吸収体３との間に不繊布等からなるセカンドシートを積層し、体液の拡散性向上を図ることもできる。さらに、両側部上に、体液の横モレ防止機能を有する起立ギャザーを設けてもよい。 A second sheet made of a non-woven cloth or the like may be laminated between the top sheet 1 and the absorbent body 3 to improve body fluid diffusibility. Furthermore, you may provide the standing gather which has a horizontal-moisture prevention function of a bodily fluid on both sides.
サイド不織布５は、図１および図２に示されるように、幅方向中間部より外側部分を吸収体３の内側位置から吸収体側縁を若干越えて不透液性バックシート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されている。なお、サイド不織布５には、体液の横モレ防止機能を有する起立ギャザーを設けてもよい。 As shown in FIG. 1 and FIG. 2, the side nonwoven fabric 5 is a range from the inner side position of the absorbent body 3 to the outer edge of the liquid-impermeable back sheet 2 slightly beyond the inner edge of the absorbent body 3 from the widthwise intermediate portion. It is bonded by an adhesive such as hot melt. The side nonwoven fabric 5 may be provided with upright gathers having a function of preventing body fluid from being laterally leaked.
バックシート２の裏面側には、通常、ショーツ等の肌着に対する止着部Ｓ１が設けられる。また、ウィングフラップＷにも止着部Ｓ２が設けられる。この止着部Ｓ１，Ｓ２は、例えば、スチレン・ブタジエン共重合体やスチレン・オレフィン共重合体等からなる粘着剤を、前後方向に帯状に塗布して形成することができる。この止着部は、装着時において生理用ナプキン１０を肌着に止着するためのものであるが、本生理用ナプキン１０を需要者に提供する段階においては、個別包装のための剥離シートなどを止着しておくこともできる。この剥離シートは、ポリエチレンシート、ポリプロピレンシート、ポリエチレンテレフタレートシート、ラミネート紙、等からなり、止着部に対して剥離可能とされる。 On the back side of the back sheet 2, a fastening portion S1 for underwear such as shorts is usually provided. The wing flap W is also provided with a fastening portion S2. The fastening portions S1 and S2 can be formed by, for example, applying a pressure-sensitive adhesive made of a styrene / butadiene copolymer, a styrene / olefin copolymer, or the like in a strip shape in the front-rear direction. This fastening part is for fastening the sanitary napkin 10 to the underwear at the time of wearing, but in the stage of providing the sanitary napkin 10 to the consumer, a release sheet for individual packaging or the like is provided. It can also be fastened.

吸収体３を構成する吸収体の素材としては、体液を吸収・保持し得るものであればいずれも使用でき、パルプ等の天然繊維の他、合成繊維を用いることもでき、または体液の吸収量を増やすために、吸水性ポリマーを用いたり、これらを適宜併用できる。合成繊維としては、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、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。吸収体中に混合される合成繊維は、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。なお、通常は、フラッフ状パルプ中に吸水性ポリマー粉末を混入したものが吸収機能および価格の点から好適に使用される。 As a material of the absorbent body constituting the absorbent body 3, any material can be used as long as it can absorb and retain body fluids. In addition to natural fibers such as pulp, synthetic fibers can also be used, or the amount of absorbed body fluids In order to increase this, a water-absorbing polymer can be used, or these can be used together as appropriate. As synthetic fibers, 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 what you did. 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. As the synthetic fiber mixed in the absorbent body, it is desirable to use a hydrophobic fiber that has been surface-treated with a hydrophilizing agent so as to have affinity for body fluids. In general, fluffed pulp mixed with water-absorbing polymer powder is preferably used from the viewpoint of absorption function and price.
吸収体３は、その形状を保持するために、包装シート４で囲繞するのが望ましい。包装シート４は、透液性を有していれば、その素材は特に限定されないが、クレープ紙等の水解性シートを好適に使用できる。吸収体３はバックシート２に対して、ホットメルトなどの接着剤やヒートシール等の接着手段によって接合される。なお、本実施形態に係る生理用ナプキン１においては、吸収体３が包装シート４で囲繞される場合は、吸収体３とバックシート２とは、包装シート４を介して間接的に接合される。 The absorbent body 3 is desirably surrounded by the packaging sheet 4 in order to maintain its shape. The material of the packaging sheet 4 is not particularly limited as long as it has liquid permeability, but a water-decomposable sheet such as crepe paper can be suitably used. The absorber 3 is bonded to the back sheet 2 by an adhesive such as hot melt or an adhesive means such as heat seal. In the sanitary napkin 1 according to this embodiment, when the absorbent body 3 is surrounded by the packaging sheet 4, the absorbent body 3 and the back sheet 2 are indirectly joined via the packaging sheet 4. .
本形態の生理用ナプキン１０の表面側には、トップシート１と吸収体３を一体化させる、複数の圧搾溝が配されている。***口に接する部分を取り囲むように、第１前方圧搾部１１、第１後方圧搾部１２、及び二つの側方圧搾部１３が設けられている。図示例においては、圧搾部１１、１２及び１３が一体として付されている。前記圧搾部１１、１２及び１３で囲繞された部分を、中央部ＣＬとする。 On the surface side of the sanitary napkin 10 of the present embodiment, a plurality of pressing grooves for integrating the top sheet 1 and the absorbent body 3 are arranged. The 1st front pressing part 11, the 1st back pressing part 12, and the two side pressing parts 13 are provided so that the part which touches an excretion port may be surrounded. In the example of illustration, the pressing parts 11, 12, and 13 are attached | subjected as integral. A part surrounded by the compressed parts 11, 12 and 13 is defined as a central part CL.
第１前方圧搾部１１の拡大図を図３、第１後方圧搾部１２の拡大図を図４に示す。第１前方圧搾部１１、第１後方圧搾部１２は、生理用ナプキン１０の幅方向中央線に対して対称な形状をしており、少なくとも一部は、長手方向外側から中央側へ向かうにつれて幅方向中央側から幅方向外側へと延在する直線状の部分を有し、いわゆる「ヘ」の字型または「ハ」の字型を呈する。当該直線状の部分が幅方向中央線Ｌに対して成す角度θ１，θ２は、３５〜６０度とする。特に４５〜６０度が好ましい。 The enlarged view of the 1st front pressing part 11 is shown in FIG. 3, and the enlarged view of the 1st back pressing part 12 is shown in FIG.

It has a linear portion extending from the center in the direction to the outside in the width direction, and exhibits a so-called “f” shape or “c” shape. Angles θ1 and θ2 formed by the straight portion with respect to the center line L in the width direction are set to 35 to 60 degrees. 45 to 60 degrees is particularly preferable.
第１前方圧搾部１１、第１後方圧搾部１２は、幅方向中央線において離間させず、左右一体とさせてもよく（いわゆる「へ」の字型）、左右を離間させてもよい（いわゆる「ハ」の字型）。左右を離間させる場合、圧搾部１１、１２の長さを一定以上確保するためには、その離間距離は０．１〜４．０ｍｍ程度とすることが好ましい。 The first front squeezing part 11 and the first rear squeezing part 12 may not be separated from each other in the width direction center line, but may be integrated in the left and right directions (so-called “h” shape), or may be separated in the left and right directions (so-called "C" shape). When separating the left and right, the separation distance is preferably set to about 0.1 to 4.0 mm in order to ensure a certain length of the compressed portions 11 and 12.
側方圧搾部１３は、直線状または曲線状のいずれの形態をとってもよいが、幅方向中央に向かって凸な緩やかな曲線（高さ０．５〜４．０ｍｍが好適）とすると、幅方向外側から中央に向かう力が圧搾部において効率よく吸収されるため好ましい。 Although the side pressing part 13 may take any form of a linear form or a curvilinear form, if it is a gentle curve (height 0.5-4.0 mm is suitable) convex toward the center of the width direction, the width direction Since the force which goes to the center from the outside is efficiently absorbed in the pressing part, it is preferable.
中央部ＣＬの長手方向の長さは、８０〜１２０ｍｍ、特に８０〜１００ｍｍとすることが好ましい。また、中央部ＣＬの幅方向の長さは、３５〜７０ｍｍ、特に４５〜６０ｍとすることが好ましい。中央部ＣＬを圧搾溝で囲繞する場合、この部分の吸収体を二層構造としてもよい。 The length of the central portion CL in the longitudinal direction is preferably 80 to 120 mm, particularly preferably 80 to 100 mm. The length in the width direction of the central portion CL is preferably 35 to 70 mm, particularly 45 to 60 m. When the central portion CL is surrounded by the compressed groove, the absorbent body in this portion may have a two-layer structure.

When there is no squeezing groove in front of the excretory opening contact part, or when only the squeezing groove having a small length in the width direction is arranged, as shown in FIG. 8 (A), the sanitary napkin is viewed from the front. In this case, a large gap is likely to be formed between the wearer's body on both sides in the width direction. This void tends to cause the leakage of excretory fluid. On the other hand, when the pressing groove having a long width in the width direction is arranged in front of the excretory opening contact portion, the position of the pressing groove does not follow the shape of the body, and therefore, it tends to be an inverted V shape (FIG. 8). (B)). When the front squeezing groove is 35 to 70 mm, the front side part of the sanitary napkin is easy to bend at the side end part of the squeezing groove along the shape of the body, as shown in FIG. It becomes a U-shape having an opening in. In this case, the gap between the sanitary napkin and the body is small, and the risk of leakage can be reduced. In particular, when the pressing groove is provided so that the absorbent body can be folded with the same width from the front to the excretory opening contact portion, the sanitary napkin can be more easily fitted to the shape of the body, which is preferable.

Further, a curved third rear pressing portion 17 that is convex rearward is disposed on the rear side. In the example of illustration, the 3rd back pressing part is provided as one with the pressing groove extended in the longitudinal direction forward from the both ends, and is provided so that the three sides of the 2nd back pressing part 16 may be surrounded. In the example of illustration, although all the 1st back pressing parts, the 2nd back pressing parts, and the 3rd back pressing parts are separated, you may give any two or all three as one.
第２後方圧搾部及び第３後方圧搾部の幅方向の長さは、３５〜７０ｍｍ、特に４５〜６０ｍｍとすることが好ましい。 It is preferable that the length of the 2nd back pressing part and the 3rd back pressing part of the width direction is 35-70 mm, especially 45-60 mm.

Both the 4th front pressing part 18 and the 4th back pressing part 19 are symmetrical compression grooves which are symmetrical with respect to the longitudinal center line and are convex forward and backward, respectively.
このように、前方及び後方にさらに圧縮溝を設けることで、***液の表面拡散防止効果を高めることができ、また、吸収体にコシをもたせて形状保持性を高めることができる。一方で、より多く圧縮溝を設けることにより、吸収体が固くなり、着用感を損なってしまう、という問題がある。そのため、前方圧搾部、後方圧搾部の数は、それぞれ３つまたは４つとすることが好ましい。 In this way, by providing further compression grooves in the front and rear, the effect of preventing the surface diffusion of excretory liquid can be enhanced, and the shape retention can be enhanced by giving the absorbent body stiffness. On the other hand, there is a problem that by providing more compressed grooves, the absorbent body becomes hard and the feeling of wearing is impaired. Therefore, it is preferable that the number of the front pressing part and the rear pressing part is three or four, respectively.
図示例においては、***口当接部の前方及び後方に、それぞれ４つの圧縮溝が設けられているが、前方が３つで後方が４つ、または、前方が４つで後方が３つとなるように配してもよい。 In the illustrated example, four compression grooves are provided in front and rear of the excretory opening contact portion, respectively, but there are three in the front and four in the rear, or four in the front and three in the rear.
