Description

本発明は、生理用ナプキン、失禁パッド、おりものシート、使い捨ておむつ等の吸収性物品に関する。   The present invention relates to absorbent articles such as sanitary napkins, incontinence pads, cage sheets, and disposable diapers.

吸収体の片面又は両面にエンボス加工を施した吸収性物品が知られている。例えば液の拡散性を高めたり、ウエットバックを減少させることを目的として、エンボスによって吸収体を裏面シート側から又は両側から圧縮し、圧縮部分と非圧縮部分とを形成した吸収性物品が提案されている（特許文献１参照）。   Absorbent articles in which one side or both sides of an absorbent body are embossed are known. For example, for the purpose of increasing liquid diffusibility or reducing wetback, an absorbent article in which an absorbent body is compressed from the back sheet side or both sides by embossing to form a compressed part and an uncompressed part has been proposed. (See Patent Document 1).

しかし前記の吸収性物品では、吸収体への液の移行性が十分に速いとは言えず、液が排泄された直後の状態では表面シートが湿潤しており、肌とのべたつき感が生じてしまう。また、吸収体の表面シート対向側の全域に亘りエンボス加工が施されているので、吸収性物品全体の曲げに対する剛性が高くなってしまい、身体とのフィット感が損なわれたり、漏れが生じやすくなってしまう。   However, in the above-mentioned absorbent article, it cannot be said that the liquid transfer property to the absorbent body is sufficiently fast, and the surface sheet is wet immediately after the liquid is excreted, resulting in a sticky feeling with the skin. End up. In addition, since the embossing is applied to the entire area of the absorbent body facing the surface sheet, the rigidity of the absorbent article as a whole is increased in rigidity, and the fit with the body is impaired or leakage is likely to occur. turn into.

特開昭５８−６５００３号公報JP 58-65003 A

従って本発明の目的は、前述した従来技術が有する種々の欠点を解消し得る吸収性物品を提供することにある。   Therefore, the objective of this invention is providing the absorbent article which can eliminate the various fault which the prior art mentioned above has.

本発明は、吸収体における裏面シート対向面側から該吸収体がエンボス加工され、該裏面シート対向面に多数の凹部が形成されて、該吸収体の面方向に亘って疎密構造が形成されていると共に、吸収体における表面シート対向面側から該吸収体が表面シートと共にエンボス加工されて、該表面シート対向面における排泄部対向領域に複数の圧着部が形成されており、
前記表面シート対向面の少なくとも排泄部対向領域において前記吸収体と前記表面シートとが密着している吸収性物品を提供することにより前記目的を達成したものである。 In the present invention, the absorbent body is embossed from the back sheet facing surface side of the absorbent body, a large number of recesses are formed on the back sheet facing surface, and a dense structure is formed across the surface direction of the absorbent body. In addition, the absorber is embossed together with the surface sheet from the surface sheet facing surface side in the absorbent body, and a plurality of pressure-bonding portions are formed in the excretory part facing region in the surface sheet facing surface,
The object is achieved by providing an absorbent article in which the absorbent body and the topsheet are in close contact with each other in at least the excretory part facing region of the topsheet facing surface.

本発明の吸収性物品は、瞬時に多量の液を吸収できるので、液の排泄直後であっても常にドライな状態が保たれ、快適な装着感が得られる。また、吸収体の全域に亘って粗密構造が形成されているので、吸収体内で液が平面方向へ拡散しやすく、吸収体全体の吸収能を余すところなく活用できる。従って、吸収容量を落とさずに、パルプや高吸収性ポリマーの使用量を低減させることができる。更に、吸収体の全域に亘ってエンボス加工が施されていることで、吸収体の保形性が高くなり、よれが発生しにくい。   Since the absorbent article of the present invention can absorb a large amount of liquid instantly, a dry state is always maintained even after the liquid is excreted, and a comfortable wearing feeling can be obtained. Further, since the dense structure is formed over the entire area of the absorbent body, the liquid easily diffuses in the planar direction within the absorbent body, and the entire absorbent capacity can be utilized. Therefore, the amount of pulp and superabsorbent polymer used can be reduced without reducing the absorption capacity. Furthermore, since the embossing is performed over the entire area of the absorbent body, the shape retaining property of the absorbent body is enhanced, and it is difficult for warpage to occur.

以下本発明を、その好ましい実施形態に基づき図面を参照しながら説明する。図１には本発明の吸収性物品の一実施形態である生理用ナプキンの斜視図が示されている。図２は図１におけるII−II線断面図である。   The present invention will be described below based on preferred embodiments with reference to the drawings. FIG. 1 shows a perspective view of a sanitary napkin which is an embodiment of the absorbent article of the present invention. 2 is a cross-sectional view taken along line II-II in FIG.

図１及び図２に示す生理用ナプキン１は、液透過性の表面シート２、液不透過性の裏面シート３、及びこれら両シート間に介在された液保持性の吸収体４を具備し、実質的に縦長に形成されている。吸収体４は、表面シート２及び裏面シート３間に挟持固定されている。表面シート２は、着用時に着用者の肌に向けられる肌当接面を形成している。本実施形態における表面シート２は、両側縁部にそれぞれ側部シート５が連設されている。側部シート５及び裏面シート３は、吸収体４の長手方向の両側縁より幅方向外方に延出し、その延出部において互いに接合されてサイドフラップ５０を形成している。また、表面シート２及び裏面シート３は、吸収体４の長手方向の両端より長手方向外方に延出し、その延出部において互いに接合されてエンドシール部６を形成している。裏面シート３及び側部シート５としては、当該技術分野において通常用いられているものを特に制限なく用いることができる。吸収体４についても同様であり、例えばパルプと高吸収性ポリマーとの積繊体を用いることができる。表面シート２の詳細については後述する。   A sanitary napkin 1 shown in FIGS. 1 and 2 includes a liquid-permeable top sheet 2, a liquid-impermeable back sheet 3, and a liquid-retaining absorbent 4 interposed between the two sheets. It is formed substantially vertically long. The absorber 4 is sandwiched and fixed between the top sheet 2 and the back sheet 3. The topsheet 2 forms a skin contact surface that is directed to the wearer's skin when worn. As for the surface sheet 2 in this embodiment, the side part sheet | seat 5 is continuously provided in the both-sides edge part, respectively. The side sheet 5 and the back sheet 3 extend outward in the width direction from both side edges in the longitudinal direction of the absorbent body 4, and are joined to each other at the extended portion to form a side flap 50. Further, the top sheet 2 and the back sheet 3 extend outward in the longitudinal direction from both ends in the longitudinal direction of the absorbent body 4, and are joined to each other at the extending portion to form an end seal portion 6. As the back sheet 3 and the side sheet 5, those normally used in the technical field can be used without any particular limitation. The same applies to the absorbent body 4, and for example, a pile of pulp and superabsorbent polymer can be used. Details of the top sheet 2 will be described later.

図２に示すように、本実施形態のナプキン１においては、吸収体４における裏面シート対向面側に多数のドット状凹部７が形成されている。ドット状凹部７は、吸収体４における裏面シート対向面の少なくとも排泄部対向領域に設けることがことが好ましく、本実施形態においては裏面シート対向面の全域に亘って形成されている。ドット状凹部７は、吸収体４における裏面シート対向面側から該吸収体４がエンボス加工されることによって形成されている。しかし、吸収体４は、後述する排泄部対向領域を除き、表面シート対向面側からはエンボス加工が施されていない。その結果、吸収体４における裏面シート対向面は凹凸面となっており、且つ表面シート対向面は実質的に平坦面になっている。但し、表面シート対向面は、ドット状凹部７を形成するときのエンボス加工の条件によっては、ドット状凹部７に対応する位置が僅かに窪んでいる場合がある。   As shown in FIG. 2, in the napkin 1 of the present embodiment, a large number of dot-shaped recesses 7 are formed on the back surface sheet facing surface side of the absorbent body 4. It is preferable to provide the dot-shaped recessed part 7 at least in the excretion part opposing area | region of the back surface opposing surface in the absorber 4, and in this embodiment, it is formed over the whole region of a back surface opposing surface. The dot-shaped recess 7 is formed by embossing the absorbent body 4 from the back sheet facing surface side of the absorbent body 4. However, the absorber 4 is not embossed from the surface facing the surface sheet except for the excretory part facing region described later. As a result, the back sheet facing surface of the absorbent body 4 is an uneven surface, and the top sheet facing surface is substantially flat. However, the surface sheet facing surface may be slightly recessed at the position corresponding to the dot-shaped recess 7 depending on the embossing conditions when forming the dot-shaped recess 7.

なお、ドット状凹部７を形成するためのエンボス加工は、吸収体４にのみ対して行われている。つまり、表面シート２や裏面シート３と共に吸収体４がエンボス加工されてドット状凹部７が形成されているのではない。   In addition, the embossing for forming the dot-shaped recessed part 7 is performed only with respect to the absorber 4. FIG. That is, the absorbent body 4 is not embossed together with the top sheet 2 and the back sheet 3 to form the dot-shaped recess 7.

更に、裏面シート対向面側から吸収体４がエンボス加工されることによって、吸収体４には、面方向に亘ってその全域に疎密構造が形成されている。具体的には圧縮されている密な部分４ａと、非圧縮状態になっている疎な部分４ｂとからなる疎密構造が形成されている。密な部分４ａは、ドット状凹部７の底部に位置している。   Furthermore, the absorber 4 is embossed from the back sheet facing surface side, whereby the absorber 4 is formed with a dense structure over the entire surface thereof. Specifically, a sparse / dense structure is formed which includes a compressed dense part 4a and a sparse part 4b in an uncompressed state. The dense portion 4 a is located at the bottom of the dot-shaped recess 7.

吸収体４に疎密構造が形成されていることで、吸収体４に二つの機能を付与することができる。一つ目は、密な部分４ａが存在することによる液の拡散性の増大機能である。密な部分４ａでは毛管力が強く働き、液は吸収体４の平面方向へ素早く拡散される。二つ目は、疎な部分４ｂが存在することによる液の透過性の増大機能である。疎な部分４ｂは、液が通過しやすい空間を有していることから、排泄された液は、吸収体４の厚さ方向へ素早く透過する。この二つの機能によって素早い液の透過及び拡散が実現し、吸収体４内で液が平面方向へ十分に拡散し、吸収体全体の吸収能を余すところなく活用できる。その結果、吸収容量を落とさずに、パルプや高吸収性ポリマーの使用量を低減させることができる。このことは、経済的な観点及び環境負荷の軽減の観点から有利である。   Since the dense structure is formed in the absorber 4, two functions can be given to the absorber 4. The first is a function of increasing the diffusibility of the liquid due to the presence of the dense portion 4a. In the dense portion 4 a, the capillary force works strongly, and the liquid is quickly diffused in the plane direction of the absorber 4. The second is a function of increasing the liquid permeability due to the presence of the sparse portion 4b. Since the sparse part 4 b has a space through which the liquid easily passes, the excreted liquid quickly permeates in the thickness direction of the absorber 4. By these two functions, quick liquid permeation and diffusion can be realized, and the liquid can be sufficiently diffused in the plane direction in the absorber 4 so that the absorption capacity of the entire absorber can be fully utilized. As a result, the amount of pulp or superabsorbent polymer used can be reduced without reducing the absorption capacity. This is advantageous from the economical viewpoint and from the viewpoint of reducing the environmental load.

吸収体４に疎密構造が形成されていることで、吸収体４の保形性が高くなり、例えば着用者が激しい動作をしても、吸収体４によれが発生しにくくなるという付加的効果もある。   By forming the dense structure in the absorbent body 4, the shape retaining property of the absorbent body 4 is increased, and for example, even if the wearer performs a violent operation, the additional effect that the absorbent body 4 is less likely to occur. There is also.

ドット状凹部７は、その面積が０．５〜１５ｍｍ2、特に１〜１０ｍｍ2であることが、液拡散に対して有効な毛管力を設計でき、且つナプキン全体の曲げに対する剛性が過度に高くならない、つまり着用者に違和感やフィットしない不安感を与えないという点から好ましい。ドット状凹部７は、縦横比が１に近い異方性の低い形状であることが好ましい。例えば円形や、矩形、三角形等の多角形などの形状をとり得る。吸収体４における裏面シート対向面に対するドット状凹部７の面積の総和の割合（以下、裏面シート対向面側面積率という）は、１〜５０％、特に２〜３０％であることが、吸収体４に所望の疎密構造を形成し得る点から好ましい。 The dot-shaped concave portion 7 has an area of 0.5 to 15 mm 2 , particularly 1 to 10 mm 2 , and can design an effective capillary force against liquid diffusion and has an excessively high rigidity against bending of the whole napkin. This is preferable because it does not give the wearer a sense of incongruity or anxiety that does not fit. It is preferable that the dot-shaped recessed part 7 is a shape with a low anisotropy whose aspect ratio is close to 1. For example, the shape may be a circle, a rectangle, a polygon such as a triangle, or the like. The ratio of the total area of the dot-shaped recesses 7 to the back sheet facing surface in the absorbent body 4 (hereinafter referred to as the back sheet facing surface area ratio) is 1 to 50%, particularly 2 to 30%. 4 is preferable in that a desired density structure can be formed.

ドット状凹部７は、ナプキン１の長手方向におけるピッチが３〜１０ｍｍ、特に３〜７ｍｍであることが、また、ナプキン１の幅方向におけるピッチが３〜１０ｍｍ、特に３〜７ｍｍであることが、液拡散に対して有効な毛管力と液透過しやすい空間を兼ね備え、この二つの機能によって素早い液の透過及び拡散が実現し、吸収体全体の吸収能を余すところなく活用できる点から好ましい。   The dot-shaped recess 7 has a pitch in the longitudinal direction of the napkin 1 of 3 to 10 mm, particularly 3 to 7 mm, and a pitch in the width direction of the napkin 1 of 3 to 10 mm, particularly 3 to 7 mm. It is preferable in that it has both a capillary force effective for liquid diffusion and a space through which liquid can easily permeate. By these two functions, quick liquid permeation and diffusion can be realized, and the absorption capacity of the entire absorbent body can be fully utilized.

先に述べた通り、吸収体４における裏面シート対向面にドット状凹部７を設けているため、吸収体４に疎密構造が形成されているとともに、吸収体４における表面シート対向面は実質的に平坦面になっている。その結果、吸収体４と表面シート２との密着性が高まり、表面シート２から吸収体４への液の移行が一層素早くなる。この観点から、後述するように、表面シート２の裏面（つまり吸収体対向面）が実質的に平坦になっていることが好ましい。   As described above, since the dot-shaped concave portion 7 is provided on the back sheet facing surface of the absorber 4, a dense structure is formed in the absorber 4, and the top sheet facing surface of the absorber 4 is substantially the same. It is a flat surface. As a result, the adhesion between the absorbent body 4 and the top sheet 2 is enhanced, and the liquid transfer from the top sheet 2 to the absorbent body 4 is further accelerated. From this viewpoint, as described later, it is preferable that the back surface (that is, the absorber-facing surface) of the topsheet 2 is substantially flat.

図１に示すように、ナプキン１には、その肌当接面側における排泄部対向領域の幅方向中央部Ａにおける複数箇所に圧着部９が形成されている。圧着部９は短い線状の形状をしている。圧着部９は、ナプキン１の長手方向に延びるように形成されている。圧着部９は、ナプキン１の長手方向に関し、所定間隔をおいて不連続に形成されている。また、ナプキン１の幅方向に関し、所定間隔をおいて多列に形成されている。   As shown in FIG. 1, the napkin 1 is formed with crimping portions 9 at a plurality of locations in the central portion A in the width direction of the excretory portion facing region on the skin contact surface side. The crimping part 9 has a short linear shape. The crimping part 9 is formed so as to extend in the longitudinal direction of the napkin 1. The crimping part 9 is formed discontinuously at a predetermined interval in the longitudinal direction of the napkin 1. Further, the napkin 1 is formed in multiple rows at predetermined intervals in the width direction.

圧着部９は、表面シート２及び吸収体４が一体的に圧縮されて形成されている。圧着部９は、吸収体４における表面シート対向面側から該吸収体４が表面シート２と共にエンボス加工されて形成されている。圧着部９においては、表面シート２がエンボスピン（図示せず）により押圧されて、表面シート２の厚み方向の全体が、吸収体４の内部に陥入すると共に、その陥入した部位において表面シート２が吸収体４に接合固定されている。そのため、表面シート２は、圧着部間において張力のかかった状態で、吸収体４に固定される。この張力が働いていることにより、着用中に身体の動きによりナプキン１に変形等が生じても、表面シート２と吸収体４との密着性が良好に維持され、表面シート２上に排泄された液が吸収体４に速やかに移行し吸収される。表面シート２と吸収体４との接合は、これらの構成繊維どうしの熱融着や接着剤による接着によって行うことができる。   The crimping part 9 is formed by compressing the top sheet 2 and the absorber 4 integrally. The crimping part 9 is formed by embossing the absorber 4 together with the surface sheet 2 from the surface facing the surface sheet of the absorber 4. In the crimping part 9, the top sheet 2 is pressed by an emboss pin (not shown), and the entire thickness direction of the top sheet 2 is invaded into the absorber 4, and the surface at the indented part The sheet 2 is bonded and fixed to the absorber 4. Therefore, the top sheet 2 is fixed to the absorber 4 in a state where tension is applied between the crimping portions. Due to this tension, even if the napkin 1 is deformed by the movement of the body during wearing, the adhesion between the topsheet 2 and the absorbent body 4 is maintained well and excreted on the topsheet 2. The liquid is quickly transferred to the absorber 4 and absorbed. The surface sheet 2 and the absorbent body 4 can be joined by heat-sealing these constituent fibers or bonding them with an adhesive.

圧着部９には、高密度／低密度部を交互に配列させてもよい。こうすることで圧着部９の剛性感が緩和され、フィット性が高まり、また液引き込み力が高まるので有効である。   In the crimping part 9, high density / low density parts may be alternately arranged. This is effective because the rigidity of the crimping part 9 is relaxed, the fitting property is increased, and the liquid drawing force is increased.

更に、圧着部９が形成された領域の外側に、全周囲に亘って防漏溝を形成するか、又は該領域の前後若しくは左右両側に連続的な防漏溝を形成することによって、該防漏溝によって圧着部９が位置決めされるので、表面シート２と吸収体４とが一層よく密着するようになる。その結果、体液の移動が促進され、また液漏れが生じないようになる。かかる防漏溝の詳細については後述する。   Further, by forming a leak-proof groove over the entire periphery outside the area where the crimping portion 9 is formed, or by forming continuous leak-proof grooves on the front and rear sides or both the left and right sides of the area, Since the crimping part 9 is positioned by the leakage groove, the topsheet 2 and the absorbent body 4 come into close contact with each other. As a result, the movement of bodily fluids is promoted and liquid leakage does not occur. Details of the leak-proof groove will be described later.

圧着部９及びドット状の凹部７それぞれの配列パターンは特に限定されるものではない。図示するように、圧着部９が製品長さ方向に略縦長に配列されることでモレ防止効果が一層高まる。また、図示はしないが、圧着部９が製品幅方向に略縦長に配列されることで製品が湾曲しやすくなり身体に対するフィット性が高まる。ドット状凹部７も吸収体全域に等間隔で規則的に配列されていてもよいし、製品の長さ方向及び幅方向に対して任意に配列させてもよい。   The arrangement pattern of each of the crimping portion 9 and the dot-like recess 7 is not particularly limited. As shown in the drawing, the effect of preventing leakage is further enhanced by arranging the crimping portions 9 substantially vertically in the product length direction. Moreover, although not shown in figure, the crimping | compression-bonding part 9 arranges substantially vertically long in the product width direction, and a product becomes easy to curve and the fitting property with respect to a body increases. The dot-shaped concave portions 7 may also be regularly arranged at equal intervals throughout the absorber, or may be arbitrarily arranged in the length direction and width direction of the product.

圧着部９とドット状の凹部７との相対的な配列パターンにも特に制限はないが、特に圧着部９の下方における吸収体４の裏面シート対向面に多数の凹部７が形成されて、吸収体４の面方向に亘った疎密構造が形成されていることが好ましい。これによって吸収体４における液の拡散性が一層促進される。また吸収体における液の透過性も一層促進される。   The relative arrangement pattern of the crimping portion 9 and the dot-like recess 7 is not particularly limited, but in particular, a large number of recesses 7 are formed on the opposite surface of the back surface of the absorbent body 4 below the crimping portion 9 to absorb. It is preferable that a sparse / dense structure extending in the surface direction of the body 4 is formed. Thereby, the diffusibility of the liquid in the absorber 4 is further promoted. Moreover, the liquid permeability in the absorber is further promoted.

後述するように、表面シート２が伸縮性を有していると、表面シート２が伸ばされながら吸収体４と一体化されているため、吸収体４の厚み方向に対してより深い位置にまで接合が生じる。そのため、表面シート２と吸収体４との密着性が一層高まり、表面シート２上に排泄された液が、圧着部を介して吸収体４に一層速やかに移行する。また、圧着部において表面シート２が吸収体４から離脱しにくいため、身体の動きに対する構造の安定性にも優れている。本実施形態のナプキン１によれば、このような作用により、表面シート上の液残りや液流れを防止でき、優れた吸収性能及び漏れ防止性能が発現されると共に湿潤感の低減された快適な装着感を得ることができる。   As will be described later, when the topsheet 2 has elasticity, the topsheet 2 is integrated with the absorbent body 4 while being stretched, so that the topsheet 2 is deeper than the absorbent body 4 in the thickness direction. Joining occurs. Therefore, the adhesiveness between the topsheet 2 and the absorbent body 4 is further increased, and the liquid excreted on the topsheet 2 moves to the absorbent body 4 more quickly through the crimping portion. Moreover, since the surface sheet 2 is unlikely to be detached from the absorbent body 4 at the crimping portion, the structural stability against the movement of the body is excellent. According to the napkin 1 of the present embodiment, the liquid residue and the liquid flow on the top sheet can be prevented by such an action, and an excellent absorption performance and leakage prevention performance are expressed and a comfortable feeling with reduced wet feeling is achieved. A feeling of wearing can be obtained.

以上の理由から、圧着部９は、ナプキン１における排泄部対向領域に形成されていることが必須であるが、それに加えて、圧着部９は排泄部対向領域にのみ形成されていることが好ましい。圧着部９をナプキン１の全域に形成すると、ナプキン１の剛性が高くなることに起因して、ナプキン１のフィットが低下し、また漏れが生じやすくなる。   For the above reasons, it is essential that the crimping part 9 is formed in the excretory part opposing region in the napkin 1, but in addition, the crimping part 9 is preferably formed only in the excretory part opposing region. . If the crimping part 9 is formed in the whole area of the napkin 1, the napkin 1 has high rigidity, so that the fit of the napkin 1 is reduced and leakage is likely to occur.

図１に示すように、圧着部９はナプキン１の長手方向に延びているのが望ましい。これによって排泄された液が圧着部９に沿って誘導されてナプキン１の長手方向に流れるようになり、ナプキン１の側部からの液漏れが防止される。また、ナプキン１の幅方向の可撓性が損なわれず、フィット性が高められという利点もある。圧着部９の長さは５〜２０ｍｍ、特に５〜１０ｍｍであることが好ましい。   As shown in FIG. 1, it is desirable that the crimping portion 9 extends in the longitudinal direction of the napkin 1. As a result, the excreted liquid is guided along the crimping part 9 and flows in the longitudinal direction of the napkin 1, and liquid leakage from the side part of the napkin 1 is prevented. In addition, there is an advantage that the flexibility in the width direction of the napkin 1 is not impaired and the fitting property is enhanced. The length of the crimping part 9 is preferably 5 to 20 mm, particularly 5 to 10 mm.

圧着部９の面積は１〜２０ｍｍ2、特に５〜１０ｍｍ2であることが、表面シート２上に排泄された液が吸収体４に一層速やかに移行し、また表面シート２が吸収体から離間しにくいという点から好ましい。吸収体４における表面シート対向面に対する圧着部９の面積の総和の割合（以下、表面シート対向面側面積率という）は、０．０１〜２．０％、特に０．０５〜１．０％という低い値であることが、吸収体４の剛性が過度に高まることを防止する点から好ましい。 The area of the crimping part 9 is 1 to 20 mm 2 , particularly 5 to 10 mm 2 , so that the liquid excreted on the top sheet 2 moves to the absorbent body 4 more quickly, and the top sheet 2 is separated from the absorbent body. It is preferable from the point of being hard to do. The ratio of the total area of the crimping portions 9 to the surface facing the surface of the absorbent body 4 (hereinafter referred to as the surface sheet facing surface area ratio) is 0.01 to 2.0%, particularly 0.05 to 1.0%. A low value of this is preferable from the viewpoint of preventing the rigidity of the absorber 4 from being excessively increased.

圧着部９は、ナプキン１の長手方向におけるピッチが５〜５０ｍｍ、特に５〜３０ｍｍであることが、ナプキン全体を湾曲させやすく、それによってナプキンを身体にフィットさせやすい点から好ましい。また、ナプキン１の幅方向におけるピッチが５〜３０ｍｍ、特に５〜２０ｍｍであることが、表面シート２が吸収体４に対して良好に密着し、排泄された液が吸収体４に一層速やかに移行すると共に、着用者に不快感を与えるような剛性を生じないという点から好ましい。   It is preferable that the crimping portion 9 has a pitch in the longitudinal direction of the napkin 1 of 5 to 50 mm, particularly 5 to 30 mm from the viewpoint that the whole napkin can be easily bent and the napkin can be easily fitted to the body. In addition, the pitch in the width direction of the napkin 1 is 5 to 30 mm, particularly 5 to 20 mm, so that the topsheet 2 adheres well to the absorbent body 4, and the excreted liquid is more promptly applied to the absorbent body 4. It is preferable from the viewpoint that it does not cause rigidity that causes discomfort to the wearer as well as shifting.

本実施形態のナプキン１においては、裏面シート対向面側面積率が、表面シート対向面側面積率よりも高くなっている。これによって、液の引き込み性を十分に高くすることができる。この観点から、裏面シート対向面側面積率／表面シート対向面側面積率の値は２〜９００、特に１０〜５００であることが好ましい。なお裏面シート対向面側面積率及び表面シート対向面側面積率そのものの値については先に述べた通りである。   In the napkin 1 of the present embodiment, the area ratio of the back sheet facing surface side is higher than the area ratio of the surface sheet facing surface side. Thereby, the drawability of the liquid can be sufficiently increased. From this viewpoint, the value of the area ratio of the back sheet facing surface / the area ratio of the facing sheet facing surface is preferably 2 to 900, particularly 10 to 500. Note that the values of the area ratio of the back sheet facing surface side and the area ratio of the surface sheet facing surface itself are as described above.

前記面積率と同様の理由により、本実施形態のナプキン１においては、その長手方向及び／又は幅方向に関し、裏面シート対向面側に形成されているドット状凹部７間のピッチよりも、表面シート対向面側に形成されている圧着部９間のピッチの方が大きくなっていることが好ましい。   For the same reason as the area ratio, in the napkin 1 of the present embodiment, the front sheet is larger than the pitch between the dot-shaped recesses 7 formed on the back sheet facing surface side in the longitudinal direction and / or the width direction. It is preferable that the pitch between the crimping portions 9 formed on the opposing surface side is larger.

図１に示すように、ナプキン１における排泄部対向領域には、圧着部９とは別に、防漏溝１０が形成されている。防漏溝１０は、圧着部９が形成されている排泄部対向領域の中央部の両側それぞれに位置しており且つ圧着部９を取り囲むように閉じた形状をしている。防漏溝１０は、ナプキン１の肌当接面側において、表面シート２と吸収体４とが連続的に接合されて形成されている。圧着部９と同様に、防漏溝１０もエンボス加工によって形成されている。   As shown in FIG. 1, a leak-proof groove 10 is formed in the excretory part facing region of the napkin 1 separately from the crimping part 9. The leak-proof grooves 10 are located on both sides of the central portion of the excretory part facing region where the crimping part 9 is formed, and have a closed shape so as to surround the crimping part 9. The leak-proof groove 10 is formed by continuously joining the topsheet 2 and the absorber 4 on the skin contact surface side of the napkin 1. As with the crimping part 9, the leak-proof groove 10 is also formed by embossing.

圧着部９の側部外方に防漏溝１０が形成されていることで、表面シート２は、圧着部間のみならず、圧着部９と防漏溝１０との間でも引き伸ばされながら吸収体４と接合されることになる。その結果、圧着部間のみならず、圧着部９と防漏溝１０との間でも、表面シート２と吸収体４との密着性が向上し、表面シート２上に排泄された液が吸収体４に更に速やかに移行し吸収される。この効果を一層顕著なものとするために、ナプキン１の製造において、初めに防漏溝１０を形成し、その後に圧着部を形成することが好ましい。この操作によって、表面シート２に効果的に張力が加わりながら、表面シート２と吸収体４とが接合するからである。   Since the leak-proof groove 10 is formed on the outer side of the crimping part 9, the topsheet 2 is stretched not only between the crimping parts but also between the crimping part 9 and the leak-proofing groove 10. 4 will be joined. As a result, not only between the crimping portions but also between the crimping portion 9 and the leak-proof groove 10, the adhesion between the topsheet 2 and the absorbent body 4 is improved, and the liquid excreted on the topsheet 2 is absorbed by the absorbent body. 4 is absorbed more rapidly. In order to make this effect more prominent, it is preferable to form the leak-proof groove 10 first and then form the crimping part in the manufacture of the napkin 1. This is because the surface sheet 2 and the absorber 4 are joined by this operation while effectively applying tension to the surface sheet 2.

本実施形態のナプキン１における表面シート２は、その表面側に多数の凸部１１を有している。凸部１１は表面シート２の表面側全域に亘り島状に形成されている。表面シート２は不織布等の繊維材料から構成されており、凸部１１内は繊維で満たされている。多数の凸部１１が形成されていることで、排泄された液が凸部１１間の凹部に流れ込みやすくなり、液が迅速に表面シート２の表面から除去される。また、表面シート２はその厚さ方向における圧縮回復性が高くなり、良好なクッション感を呈する。更に、肌との接触面積が低減するので、蒸れが防止されドライ感が一層高くなる。これらの観点から、凸部１１はその高さが０．３〜５ｍｍ、特に０．５〜３ｍｍであることが好ましい。また、表面シート１を平面視したとき、凸部１１はその面積が０．５〜１０ｍｍ2、特に１〜５ｍｍ2であることが好ましい。 The topsheet 2 in the napkin 1 of the present embodiment has a large number of convex portions 11 on the surface side. The convex portion 11 is formed in an island shape over the entire surface side of the topsheet 2. The top sheet 2 is made of a fiber material such as a non-woven fabric, and the convex portion 11 is filled with fibers. By forming many convex parts 11, it becomes easy for the excreted liquid to flow into the concave part between the convex parts 11, and a liquid is removed from the surface of the surface sheet 2 rapidly. Moreover, the surface sheet 2 has a high compression recovery property in the thickness direction and exhibits a good cushion feeling. Furthermore, since the contact area with the skin is reduced, stuffiness is prevented and the dry feeling is further enhanced. From these viewpoints, the height of the convex portion 11 is preferably 0.3 to 5 mm, particularly 0.5 to 3 mm. Moreover, when the surface sheet 1 is planarly viewed, the convex portion 11 preferably has an area of 0.5 to 10 mm 2 , particularly 1 to 5 mm 2 .

一方、表面シート２の裏面は表面よりも平坦になっている。具体的には、表面シート２の裏面は実質的に平坦になっているか、或いは平坦になっていない場合であっても、表面シート２の表面よりは平坦になっている。このことと、吸収体４の表面シート対向面が平坦になっていることによって、表面シート２と吸収体４との密着性が向上する。   On the other hand, the back surface of the top sheet 2 is flatter than the front surface. Specifically, even if the back surface of the top sheet 2 is substantially flat or not flat, it is flatter than the surface of the top sheet 2. By this and the surface sheet opposing surface of the absorber 4 being flat, the adhesiveness of the surface sheet 2 and the absorber 4 improves.

表面シート２と吸収体４との密着性を一層高める観点から、先に述べた通り、表面シート２は伸縮性を有していることが好ましい。表面シート２に伸縮性を付与するためには、例えば表面シート２の構成繊維として、素材自体が伸縮性を示す弾性繊維や、立体捲縮繊維などの特定の立体構造を有することにより伸縮性を示す繊維を用いればよい。素材自体が伸縮性を示す弾性繊維としては、スチレン−ブタジエン、ブタジエン、イソプレン、ネオプレン等の合成ゴム、天然ゴム等のエラストマー材料を溶融紡糸して得られる繊維や、スパンデックスに代表されるポリウレタンやポリエステル等を組成とする合成繊維が挙げられる。特定の立体構造を有することにより伸縮性を示す繊維としては、螺旋状に捲縮した立体捲縮繊維が特に好ましく用いられる。例えば、熱処理により螺旋状の捲縮を発現した潜在捲縮性繊維が挙げられる。   From the viewpoint of further improving the adhesion between the topsheet 2 and the absorber 4, it is preferable that the topsheet 2 has stretchability as described above. In order to impart stretchability to the topsheet 2, for example, as a constituent fiber of the topsheet 2, the material itself has a specific three-dimensional structure such as elastic fiber exhibiting stretchability or a three-dimensional crimped fiber. The fibers shown may be used. Examples of elastic fibers whose material itself is stretchable include fibers obtained by melt spinning elastomer materials such as synthetic rubber such as styrene-butadiene, butadiene, isoprene, and neoprene, and natural rubber, and polyurethane and polyester represented by spandex. Synthetic fibers having a composition such as As the fiber exhibiting stretchability by having a specific three-dimensional structure, a three-dimensional crimped fiber crimped in a spiral shape is particularly preferably used. For example, the latent crimpable fiber which expressed the helical crimp by heat processing is mentioned.

表面シート２は、その表面側から裏面側に向けて漸次密な構造となっていることが好ましい。これによって液の引き込み性が一層高くなり、液が素早く吸収体４にまで移行する。この場合、表面側から裏面側に向けて連続的に密な構造になっていてもよく、或いは段階的に密な構造になっていてもよい。同様の理由により、表面シート２は、その表面側から裏面側に向けて漸次親水性が高くなっていることも好ましい。この場合、表面側から裏面側に向けて連続的に親水性が高くなっていてもよく、或いは段階的に親水性が高くなっていてもよい。   It is preferable that the surface sheet 2 has a gradually dense structure from the front surface side toward the back surface side. As a result, the drawability of the liquid is further increased, and the liquid quickly moves to the absorber 4. In this case, it may have a dense structure continuously from the front side to the back side, or may have a dense structure in stages. For the same reason, it is also preferable that the topsheet 2 has gradually increased hydrophilicity from the front side to the back side. In this case, the hydrophilicity may increase continuously from the front side to the back side, or the hydrophilicity may increase stepwise.

表面シート２の表面側から裏面側に向けて漸次密な構造を作るには、例えば表面シート２を２層以上の多層構造となし、下側の層に向かうほど繊維密度の高い層を用いればよい。同様に、表面シート２の表面側から裏面側に向けて漸次親水性の高い構造を作るには、例えば表面シート２を２層以上の多層構造となし、下側の層に向かうほど親水度の高い層を用いればよい。親水性に関しては、液を繰り返し吸収しても親水性が低下しづらい特性、即ち安定な耐久親水性を有していることが望ましい。   In order to make a gradually dense structure from the front surface side to the back surface side of the top sheet 2, for example, the top sheet 2 has a multilayer structure of two or more layers, and a layer with higher fiber density is used as it goes to the lower layer. Good. Similarly, in order to make a structure having gradually higher hydrophilicity from the front surface side to the back surface side of the top sheet 2, for example, the top sheet 2 has a multilayer structure of two or more layers, and the hydrophilicity is increased toward the lower layer. A high layer may be used. Regarding the hydrophilicity, it is desirable that the hydrophilicity is not easily lowered even when the liquid is repeatedly absorbed, that is, it has stable durable hydrophilicity.

本実施形態のナプキン１に好ましく用いられる表面シート２の具体的な例としては、本出願人の先の出願に係る特開２００２−１６５８３０号公報、特開２００２−１８７２２８号公報、特開２００３−１２６１４７号公報、特開２００３−２４７１５５号公報、特開２００３−２５０８３６号公報等に記載のシートが挙げられる。   Specific examples of the surface sheet 2 preferably used for the napkin 1 of the present embodiment include Japanese Patent Application Laid-Open Nos. 2002-165830, 2002-187228, and 2003- Examples include sheets described in 126147, JP-A 2003-247155, JP-A 2003-250836, and the like.

次に本実施形態のナプキンの好ましい製造方法について説明する。先ず、吸収体をその一面側（裏面シート対向面側）からエンボス加工する。エンボス加工には、周面に多数の凸状ピンが規則的に植設されたロールと平滑ロールとの組み合わせからなるエンボス装置が用いられる。エンボス加工の際には、ロールを所定温度に加熱してドット状凹部７が効果的に形成されるようにしてもよい。   Next, the preferable manufacturing method of the napkin of this embodiment is demonstrated. First, an absorber is embossed from the one surface side (back sheet opposing surface side). For embossing, an embossing device composed of a combination of a roll in which a number of convex pins are regularly planted on a peripheral surface and a smooth roll is used. During embossing, the rolls may be heated to a predetermined temperature so that the dot-shaped recesses 7 are effectively formed.

次に、表面シート２が吸収体４上に位置するように、表面シート２を吸収体４上に重ねた後、この積層体に対して、溝形成用のエンボス加工を施して、表面シート２及び吸収体４に防漏溝１０，１０を熱圧形成する。このエンボス加工は、例えば防漏溝１０に対応する環状の突条部が周面に形成された凹凸ロールと、周面が表面平滑な弾性体からなる受けロールとの間に前記積層体を挿通して行う。   Next, after superposing the topsheet 2 on the absorber 4 so that the topsheet 2 is positioned on the absorber 4, the laminate is embossed to form grooves, and the topsheet 2 And the leakproof grooves 10 and 10 are formed in the absorber 4 by hot pressure. This embossing is performed, for example, by inserting the laminated body between an uneven roll in which an annular ridge corresponding to the leak-proof groove 10 is formed on the circumferential surface and a receiving roll made of an elastic body having a smooth circumferential surface. And do it.

次いで、防漏溝１０形成後の積層体における防漏溝１０の内側にエンボス加工を施して圧着部９を形成する。このエンボス加工には、周面に多数の凸状ピンが規則的に植設されたロールと平滑ロールとの組み合わせからなるエンボス装置が用いられる。   Next, the pressure-bonding portion 9 is formed by embossing the inside of the leak-proof groove 10 in the laminated body after the leak-proof groove 10 is formed. For this embossing, an embossing device composed of a combination of a roll and a smooth roll in which a large number of convex pins are regularly planted on the peripheral surface is used.

更に、この積層体の吸収体側に裏面シート３を積層して公知の手法により接合し、更に公知の手法により輪郭をナプキン１の形状に切断すると共にエンドシールを施し、本実施形態の生理用ナプキン１を得る。   Further, the back sheet 3 is laminated on the absorber side of the laminate and joined by a known method, and the contour is cut into the shape of the napkin 1 and an end seal is applied by a known method, whereby the sanitary napkin of this embodiment is used. Get one.

本実施形態の製造方法によれば、防漏溝１０の形成後に、両防漏溝１０の内側に圧着部９を形成することにより、表面シート２に自然に強い張力が掛かり、その状態で表面シート２が吸収体４に固定される。しかも圧着部９においては表面シートが大きく伸ばされながら吸収体に接合するため、強い接合強度が得られると共に圧着部９以外の部位における表面シート２と吸収体４との密着性も一層向上する。   According to the manufacturing method of the present embodiment, after forming the leak-proof grooves 10, by forming the crimping portion 9 inside both the leak-proof grooves 10, the surface sheet 2 is naturally subjected to a strong tension, and in this state, the surface The sheet 2 is fixed to the absorber 4. Moreover, since the surface sheet is joined to the absorber while the surface sheet is greatly stretched in the crimping portion 9, strong joint strength is obtained, and the adhesion between the surface sheet 2 and the absorber 4 in a portion other than the crimping portion 9 is further improved.

以上、本発明のその好ましい実施形態に基づき説明したが、本発明は前記実施形態に制限されない。例えば前記実施形態においては表面シート２として、その表面側に多数の凸部１１を有するものを用いたが、これに代えて、表面側及び裏面側ともに平坦なシートを用いてもよい。   As mentioned above, although demonstrated based on the preferable embodiment of this invention, this invention is not restrict | limited to the said embodiment. For example, in the above-described embodiment, the surface sheet 2 having a large number of convex portions 11 on the front surface side is used, but instead, a flat sheet on both the front surface side and the back surface side may be used.

また、前記実施形態のナプキンの製造方法においては、防漏溝１０の形成前に、圧着部９を形成し、その後に防漏溝１０を形成してもよい。   In the napkin manufacturing method of the above embodiment, the pressure-bonding portion 9 may be formed before the leak-proof groove 10 is formed, and then the leak-proof groove 10 may be formed.

また、吸収体４の表面シート対向面側に形成される圧着部９の形状は線状に限られない。例えばドット状、点線状、折れ線状、曲線状、多角形状、円形状、矩形状、中抜きの円形や矩形状、多角形状の複数の凹部が実質的に線状に連なった凹部群から圧着部が構成されていてもよい。圧着部が例えば複数のドット状凹部が実質的に線状に連なった凹部群からなる場合、各ドット状凹部はその面積が０．５〜２．０ｍｍ2、特に１〜１．０ｍｍ2であることが好ましい。ドット状凹部間の距離は５ｍｍ以下、特に３ｍｍ以下であることが、圧着部の延びる方向に液を効果的に誘導し得る点から好ましい。 Moreover, the shape of the crimping | compression-bonding part 9 formed in the surface sheet opposing surface side of the absorber 4 is not restricted to a linear form. For example, dot, dotted, polygonal, curved, polygonal, circular, rectangular, hollow, rectangular, rectangular, or polygonal concave portions are formed from a group of concave portions that are substantially linearly connected. May be configured. If the crimp portion, for example a plurality of dot-like recesses consist of depressions which continues to the substantially linear, each dot-shaped recess has its area is 0.5 to 2.0 mm 2, in particular 1～1.0Mm 2 It is preferable. The distance between the dot-shaped recesses is preferably 5 mm or less, particularly 3 mm or less from the viewpoint that the liquid can be effectively guided in the extending direction of the crimping part.

同様に、吸収体４の裏面シート対向面側に形成される凹部７の形状はドット状に限られない。例えば凹部の形状を線状、楕円状、中抜き円状、波線状とすることができる。或いはそれらの任意の二以上の組み合わせからなるパターンとすることもできる。   Similarly, the shape of the recessed part 7 formed in the back surface sheet opposing surface side of the absorber 4 is not restricted to a dot shape. For example, the shape of the recess can be linear, elliptical, hollow, or wavy. Or it can also be set as the pattern which consists of those arbitrary 2 or more combinations.

更に前記実施形態においては、凹部７は、吸収体４の何れの位置においても同じ深さで形成されていたが、この深さを吸収体４の部位ごとに変えることができる。圧着部９についても同様である。こうすることによって、ナプキンの柔軟性やフィット性を向上させつつ、所望の吸収力が得られるという利点が生じる。   Furthermore, in the said embodiment, although the recessed part 7 was formed in the same depth in any position of the absorber 4, this depth can be changed for every site | part of the absorber 4. FIG. The same applies to the crimping part 9. By doing so, there is an advantage that a desired absorption force can be obtained while improving the flexibility and fit of the napkin.

また前記実施形態は本発明の吸収性物品を生理用ナプキンに適用した例であるが、本発明はこの他に、例えば失禁パッド、おりものシート、使い捨ておむつなど各種吸収性物品に適用することができる。   Moreover, although the said embodiment is an example which applied the absorbent article of this invention to the sanitary napkin, this invention can be applied to various absorbent articles, such as an incontinence pad, a cage sheet, a disposable diaper, for example. it can.
