従来、その表面から厚さ方向へ凹となる圧搾条溝が形成された体液吸収性物品は公知である。例えば、特許文献１には、端部域において複数本のラインからなる交差部とそれを囲繞するように形成された曲状部とからなる第１圧搾部と、中央域に位置する網目状の第２圧搾部とを有する体液吸収性物品が開示されている。   2. Description of the Related Art Conventionally, a body fluid absorbent article in which a compressed groove that is concave in the thickness direction from the surface is formed is known. For example, Patent Document 1 includes a first squeezed portion composed of an intersecting portion composed of a plurality of lines in an end region and a curved portion formed so as to surround it, and a mesh-like shape located in the central region. A body fluid absorbent article having a second compressed portion is disclosed.

米国特許公開第２００８／０２８１２８７号公報US Patent Publication No. 2008/0281287

特許文献１に開示された体液吸収性物品によれば、第１及び第２圧搾部が形成されていることによって、着用者の身体に対するフィット性が向上するとともに、体液の流れをコントロールし、その横漏れを防止することができる。また、第１及び第２圧搾部は、幾何学的な模様を有しており、装飾効果を発揮しうるものといえる。   According to the bodily fluid absorbent article disclosed in Patent Document 1, the first and second compressed parts are formed, thereby improving the fit to the wearer's body and controlling the flow of bodily fluids. Side leakage can be prevented. Moreover, it can be said that the 1st and 2nd pressing part has a geometric pattern, and can exhibit a decoration effect.

しかし、その製造工程において、機械方向と製品の縦方向とを直交させた状態で製造ライン上を搬送させたときには（いわゆる、横流し製法）、その横方向（機械方向）の長さ寸法が大きい部位では圧力が分散されてむらが生じるおそれある。かかる場合には、所望の形状に賦型することが困難となってその輪郭形状が不明瞭となり、前記効果を発揮することができないおそれがある。   However, in the manufacturing process, when the machine direction is conveyed on the production line in a state where the machine direction is perpendicular to the product (so-called cross-flow manufacturing method), the part having a large length in the horizontal direction (machine direction) Then, pressure may be dispersed and unevenness may occur. In such a case, it is difficult to mold into a desired shape, the contour shape becomes unclear, and there is a possibility that the effect cannot be exhibited.

一方、かかる問題を解消するために、プレス手段（プレスローラー）によってエンボス手段（エンボスロール）に向かって負荷される力を大きくすることでその圧力を高めることもできるが、その場合には、エンボス手段のエンボスピンが摩耗し易くなるおそれがある。また、比較的に強い負荷でプレスした場合には、物品のトップシートの一部が破れて、外観を損ねるばかりではなく、体液の漏れを生じるおそれもある。   On the other hand, in order to solve this problem, the pressure can be increased by increasing the force applied to the embossing means (embossing roll) by the press means (press roller). There is a possibility that the embossed spin of the means is likely to be worn. In addition, when pressed with a relatively strong load, a part of the top sheet of the article is torn, not only deteriorating the appearance, but also possibly causing leakage of body fluids.

そこで、この発明では、比較的に大きな力でプレスすることなく、圧搾条溝のうちの装飾効果を有する装飾部に所要の圧力を加えてその輪郭形状をより明瞭に視認することのできる体液吸収性物品の提供を目的とする。   Therefore, in the present invention, body fluid absorption that allows a required pressure to be applied to a decorative portion having a decorative effect in the compressed groove without pressing with a relatively large force so that the contour shape thereof can be visually recognized more clearly. The purpose is to provide sex goods.

図４は、吸収構造体４５の平面図、図５は、図４の一点鎖線Ｖで示した領域の拡大図である。なお、以下の説明において、生理用ナプキン１０の縦軸Ｐの方向は、その製造時における製造工程の機械方向ＭＤを意味し、横軸Ｑの方向は、機械方向ＭＤの直交方向ＣＤを意味する。また、第１区域１６と第２区域１７とに形成された圧搾条溝２０の圧搾パターンは、縦軸Ｐ及び横軸Ｑに関して非対称であるが、その形状はほぼ同じである。よって、そのパターン形状について、主として第１区域１６についてのみ説明する。 Figure 4 is a plan view of the absorbent structure 45, FIG. 5 is an enlarged view of a region indicated by a chain line in FIG. 4 V. In the following description, the direction of the vertical axis P of the sanitary napkin 10 means the machine direction MD of the manufacturing process at the time of manufacture, and the direction of the horizontal axis Q means the orthogonal direction CD of the machine direction MD. . Moreover, although the pressing pattern of the pressing groove 20 formed in the 1st area 16 and the 2nd area 17 is asymmetrical about the vertical axis P and the horizontal axis Q, the shape is substantially the same. Therefore, only the first area 16 will be described with respect to the pattern shape.

図４，５に示した吸収構造体４５は、生理用ナプキン１０からサイドシート３１とバックシート１２とを取り除いた、トップシート１１と、中間シート１４及び芯材１３とから構成されたものである。なお、吸収構造体４５は、本発明の所要の効果を奏する限りにおいて、トップシート１１及び／または中間シート１４を有するものではなく、芯材１３のみから形成されていてもよい。   The absorbent structure 45 shown in FIGS. 4 and 5 is composed of a top sheet 11, an intermediate sheet 14, and a core material 13 obtained by removing the side sheet 31 and the back sheet 12 from the sanitary napkin 10. . In addition, as long as there exists the effect of this invention, the absorption structure 45 does not have the top sheet 11 and / or the intermediate sheet 14, and may be formed only from the core material 13. FIG.

図４に示すとおり、圧搾条溝２０の外周部２１と曲状部２４とにおいては、一対の略角形状の高圧搾部１９ａが点状に所与寸法離間した状態で多数配置されている。一方、第１及び第２装飾部２２，２３は略ハート形状の輪郭を有し、これらにおいては、略円形状の高圧搾部１９ｂが点状に所与寸法離間した状態で多数配置されている。高圧搾部１９ａ，１９ｂは、第１及び第２装飾部２２，２３にのみ形成されていてもよい。このように、高圧搾部１９ａ，１９ｂが第１及び第２装飾部２２，２３に形成されている場合には、低圧搾部１９ｃと高圧搾部１９ａ，１９ｂとが交互に配置されていることによって、そのデザイン形状をより立体的かつ明瞭に視認させることができる。なお、後記の本発明の効果を奏する限りにおいて、圧搾条溝２０には、高圧搾部１９ａ，１９ｂが形成されていなくてもよい。   As shown in FIG. 4, in the outer peripheral part 21 and the curved part 24 of the pressing groove 20, many pairs of substantially square shaped high-pressure parts 19a are arranged in a state of being spaced apart by a given dimension. On the other hand, the 1st and 2nd decoration parts 22 and 23 have a substantially heart-shaped outline, In these, many substantially circular shaped pressing parts 19b are arrange | positioned in the state spaced apart by the given dimension in the dot form. . The high pressing parts 19a and 19b may be formed only on the first and second decorative parts 22 and 23. Thus, when the high pressing parts 19a and 19b are formed in the first and second decorative parts 22 and 23, the low pressing parts 19c and the high pressing parts 19a and 19b are alternately arranged. Therefore, the design shape can be visually recognized more three-dimensionally and clearly. In addition, as long as there exists an effect of this invention of a postscript, the high pressing parts 19a and 19b do not need to be formed in the pressing groove 20.

芯材１３の縦軸Ｐの方向の長さ寸法Ｌ１は、１８０〜２２０ｍｍであって、第１区域１６の長さ寸法Ｌ２は、約５０〜９０ｍｍである。また、芯材１３の横軸Ｑの方向の長さ寸法Ｗ１は約５０〜９０ｍｍであって、外周部２１の最も幅寸法の大きい最大幅部位４９間の横軸Ｑの方向の長さ寸法Ｗ２は、約４０〜６０ｍｍである。外周部２１は、最大幅部位４９から外端縁２１ａに向かって緩やかに幅狭となるとともに、横軸Ｑに向かって幅狭となっており、その最大幅部位４９近傍間に第１及び第２装飾部２２，２３が形成されている。第１及び第２装飾部２２，２３は、その先端部２２ａ，２３ａどうしが向かい合うように、縦軸Ｐに関して互いに斜めに配置されている。説明の便宜上、外周部２１と曲状部２４との間には、外周部２１の一部と第１及び第２装飾部２２，２３とから形成された装飾圧搾域５１（図５において２点鎖線で囲んだ領域であって、外周部２１の一部と第１及び第２装飾部２２，２３以外の部分は除く。）が画成されている。 The length dimension L1 of the core material 13 in the direction of the longitudinal axis P is 180 to 220 mm, and the length dimension L2 of the first section 16 is about 50 to 90 mm. The horizontal axis towards the length W1 of the direction A about 50～90Mm, towards the length of the direction of the transverse axis Q between larger maximum width portion 49 of the widest dimension of the outer peripheral portion 21 of the Q of the core 13 The dimension W2 is about 40-60 mm. The outer peripheral portion 21 is gradually narrowed from the maximum width portion 49 toward the outer end edge 21 a and is narrowed toward the horizontal axis Q. Two decorative portions 22 and 23 are formed. The 1st and 2nd decoration parts 22 and 23 are mutually diagonally arrange | positioned regarding the vertical axis | shaft P so that the front-end | tip parts 22a and 23a may face each other. For convenience of explanation, a decorative compressed area 51 (two points in FIG. 5) formed between a part of the outer peripheral portion 21 and the first and second decorative portions 22 and 23 is provided between the outer peripheral portion 21 and the curved portion 24. This is a region surrounded by a chain line, and a part of the outer peripheral portion 21 and portions other than the first and second decorative portions 22 and 23 are excluded).

図６は、生理用ナプキン１０の製造工程の一部であるエンボスプレス工程５２を示す図、図７は、エンボスロール５５の外周面の一部拡大図、図８は、生理用ナプキン１０の製造工程における吸収構造体４５の一部拡大平面図である。図６において、機械方向はＭＤ、直交方向はＣＤで示しており、また、図８において、線圧領域Ｔ１〜Ｔ４内の圧搾条溝２０の面積Ｓ１〜４は、説明の便宜上、斜線で示している。   6 is a diagram showing an embossing press step 52 which is a part of the manufacturing process of the sanitary napkin 10, FIG. 7 is a partially enlarged view of the outer peripheral surface of the embossing roll 55, and FIG. 8 is a manufacturing of the sanitary napkin 10. It is a partially expanded plan view of the absorption structure 45 in the process. In FIG. 6, the machine direction is indicated by MD, and the orthogonal direction is indicated by CD. In FIG. 8, the areas S1 to S4 of the compressed groove 20 in the linear pressure regions T1 to T4 are indicated by oblique lines for convenience of explanation. ing.

図６に示すとおり、機械方向ＭＤに移動する搬送ベルト（搬送手段）５３上には、複数の吸収構造体４５が載置されている。吸収構造体４５は、トップシート１１と、中間シート１４と、芯材１３とが積層されて形成されたものであって、ほぼ均一の所要の厚さを有している。吸収構造体４５はそれを形成するための所要の工程を経たのちに、エンボスプレス工程５２において、その表面に圧搾条溝２０が形成される。   As shown in FIG. 6, a plurality of absorption structures 45 are placed on a transport belt (transport means) 53 that moves in the machine direction MD. The absorbent structure 45 is formed by laminating the top sheet 11, the intermediate sheet 14, and the core material 13, and has a substantially uniform required thickness. After the absorption structure 45 has undergone a necessary process for forming it, the embossing press process 52 forms the compressed groove 20 on the surface thereof.

具体的には、エンボスプレス工程５２は、搬送ベルト５３の上方に位置する、時計周りに回転する外周面が平滑なプレスローラー５４と、それと対向配置された反時計周りに回転するエンボスロール５５とから構成されている。エンボスロール５５の外周面５５ａには、圧搾条溝２０のパターンと同形状を有する、所定温度に加熱されたエンボス部５７が形成されている。エンボス部５７は、圧搾条溝２０の高圧搾部１９ａ，１９ｂに対応した多数の凸部５６ａ，５６ｂを有する。具体的には、エンボス部５７はエンボスロール５５の外周面５５ａから突出しており、凸部５６ａ，５６ｂは、エンボス部５７の他領域よりもさらに突出している。また、凸部５６ａは、圧搾条溝２０の高圧搾部１９ａに対応した略角形状を有しており、凸部５６ｂは、高圧搾部１９ｂに対応した略円形状を有している。 Specifically, the embossing press step 52 includes a press roller 54 that is positioned above the transport belt 53 and has a smooth outer peripheral surface that rotates clockwise, and an embossing roll 55 that rotates counterclockwise and is opposed to the press roller 54. It is composed of On the outer peripheral surface 55a of the embossing roll 55, an embossed portion 57 having the same shape as the pattern of the pressing groove 20 and heated to a predetermined temperature is formed. The embossed portion 57 has a large number of convex portions 56a and 56b corresponding to the high pressure portions 19a and 19b of the compressed groove 20. Specifically, the embossed portion 57 protrudes from the outer peripheral surface 55 a of the embossing roll 55, and the convex portions 56 a and 56 b further protrude from other areas of the embossed portion 57. Moreover, the convex part 56a has the substantially square shape corresponding to the high pressing part 19a of the pressing groove 20, and the convex part 56b has the substantially circular shape corresponding to the high pressing part 19b.

プレスローラー５４とエンボスロール５５とは、所定の曲率半径を有するほぼ同形同大であり、直径Ｄ約２５０〜３５０ｍｍ、直交方向ＣＤの幅寸法Ｗ３約４００〜５００ｍｍであって、互いに約０〜１．２ｍｍ離間した状態で対向配置されている。プレスローラー５４とエンボスロール５５間に形成されたクリアランスに約１．５〜５．０ｍｍの厚さを有する吸収構造体４５を圧接された状態で通過させることによって、エンボスロール５５のエンボス部５７とプレスローラー５４の外周面とによる線圧を吸収構造体４５に負荷することができる。   The press roller 54 and the embossing roll 55 are substantially the same shape and size having a predetermined radius of curvature, have a diameter D of about 250 to 350 mm, and a width dimension W3 of the orthogonal direction CD of about 400 to 500 mm. Opposed to each other with a distance of 1.2 mm. By passing the absorbent structure 45 having a thickness of about 1.5 to 5.0 mm in a pressed state through a clearance formed between the press roller 54 and the embossing roll 55, an embossing portion 57 of the embossing roll 55 and A linear pressure due to the outer peripheral surface of the press roller 54 can be applied to the absorption structure 45.

吸収構造体４５の各部に負荷される圧力は、吸収構造体４５とエンボス部５７との圧接面積、すなわち、機械方向ＭＤにおける線圧幅を単位幅とする、直交方向ＣＤに延びる領域のエンボス部５７の総面積の大きさに応じて異なる。よって、線圧される領域における圧接面積が小さいほど圧接される部位に加えられる圧力は高くなり、一方、圧接面積が大きいほどに該部位に加えられる圧力は小さくなるといえる。   The pressure applied to each part of the absorbent structure 45 is a pressure contact area between the absorbent structure 45 and the embossed part 57, that is, an embossed part in a region extending in the orthogonal direction CD, in which the linear pressure width in the machine direction MD is a unit width. Depending on the total area size of 57. Therefore, it can be said that the smaller the pressure contact area in the region to be linearly pressed, the higher the pressure applied to the pressed part, while the larger the pressure contact area, the smaller the pressure applied to the part.

図７及び図８において、一定幅を有する一点鎖線で示された領域Ｔ１〜Ｔ４は、エンボスプレス工程５２において吸収構造体４５に負荷される線圧領域を示すものであって、その一定の単位幅（線圧幅）Ｗ３は、約３．０ｍｍである。線圧領域Ｔ１における圧搾条溝２０の第１面積Ｓ１（外周部２１の外端縁２１ａの近傍領域）は、線圧領域Ｔ２における圧搾条溝２０の総面積、すなわち、外周部２１の一部の面積Ｓ２ａ，Ｓ２ｃと、曲状部２４の一部の面積Ｓ２ｂとの総和からなる第２面積Ｓ２よりも大きくなっている。また、線圧領域Ｔ２の第２面積Ｓ２は、装飾圧搾域５１内の線圧領域Ｔ３における外周部２１の一部の面積Ｓ３ａ，Ｓ３ｃと、第１装飾部２２の一部の面積Ｓ３ｂとの総和からなる第３面積Ｓ３よりも大きくなっている。 7 and 8, regions T1 to T4 indicated by a one-dot chain line having a constant width indicate a linear pressure region loaded on the absorbent structure 45 in the embossing press step 52, and the constant unit thereof. The width (linear pressure width) W3 is about 3.0 mm. The first area S1 of the compressed groove 20 in the linear pressure region T1 (region in the vicinity of the outer edge 21a of the outer peripheral portion 21) is the total area of the compressed groove 20 in the linear pressure region T2, that is, a part of the outer peripheral portion 21. Are larger than the second area S2 formed by the sum of the areas S2a and S2c of the first and second areas S2b of the curved portion 24 . In addition, the second area S2 of the linear pressure region T2 includes a partial area S3a, S3c of the outer peripheral portion 21 in the linear pressure region T3 in the decorative compressed region 51 and a partial area S3b of the first decorative portion 22. It is larger than the third area S3 made of the sum.

さらに、装飾圧搾域５１内の線圧領域Ｔ４における外周部２１の一部の面積Ｓ４ａ，Ｓ４ｅと、第１及び第２装飾部２２，２３の一部の面積Ｓ４ｂ，Ｓ４ｃ，Ｓ４ｄとの総和からなる第４面積Ｓ４よりも、線圧領域Ｔ２の第２面積Ｓ２は大きくなっている。装飾圧搾域５１においては全て同様であって、すなわち、装飾圧搾域５１内のどの部分においても、線圧領域内の圧搾条溝２０の面積は、外周線圧領域Ｔ１，Ｔ２の第１及び第２面積Ｓ１，Ｓ２よりも小さくなっている。   Furthermore, from the sum of the partial areas S4a, S4e of the outer peripheral portion 21 in the linear pressure region T4 in the decorative compressed region 51 and the partial areas S4b, S4c, S4d of the first and second decorative portions 22, 23. The second area S2 of the linear pressure region T2 is larger than the fourth area S4. In the decorative squeezing area 51, all are the same, that is, in any part in the decorative squeezing area 51, the area of the squeezing groove 20 in the linear pressure area is the first and the second in the outer peripheral linear pressure areas T1, T2. It is smaller than the two areas S1 and S2.

具体的には、線圧領域Ｔ１における第１面積Ｓ１は、約２２．０〜５５．０ｍｍ２、好ましくは、約３０．０〜５０．０ｍｍ２、線圧領域Ｔ２における第２面積Ｓ２は、約１８．０〜６０．０ｍｍ２、好ましくは、約３５．０〜５５．０ｍｍ２、さらに言えば、第２面積Ｓ２の面積Ｓ２ａと面積Ｓ２ｃとの和が約１５．０〜３０．０ｍｍ２、面積Ｓ２ｂは、約３〜３０ｍｍ２であることが好ましい。また、線圧領域Ｔ３における第３面積Ｓ３及び線圧領域Ｔ４における第４面積Ｓ４は、約１５．０〜３０．０ｍｍ２、好ましくは、約２０．０〜２５．０ｍｍ２、さらに言えば、面積Ｓ３ｂ、または、面積Ｓ４ｂ，Ｓ４ｃ，Ｓ４ｄの総和は、約８．０〜１２．０ｍｍ２、好ましくは、約８．５〜１１．０ｍｍ２である。 Specifically, the first area S1 in the linear pressure region T1 is about 22.0 to 55.0 mm 2 , preferably about 30.0 to 50.0 mm 2 , and the second area S2 in the linear pressure region T2 is About 18.0 to 60.0 mm 2 , preferably about 35.0 to 55.0 mm 2. More specifically, the sum of the area S 2 a and the area S 2 c of the second area S 2 is about 15.0 to 30.0 mm 2. The area S2b is preferably about 3 to 30 mm 2 . The third area S3 in the linear pressure region T3 and the fourth area S4 in the linear pressure region T4 are about 15.0 to 30.0 mm 2 , preferably about 20.0 to 25.0 mm 2 , The sum of the area S3b or the areas S4b, S4c, and S4d is about 8.0 to 12.0 mm 2 , and preferably about 8.5 to 11.0 mm 2 .

このように、装飾圧搾域５１において、線圧幅（約３ｍｍ）を単位幅とする圧搾条溝２０の総面積が、他の領域に比して小さくなっていることから、該領域には、外周部２１の外端縁２１ａ及び曲状部２４よりも高い圧力が負荷されて、その密度は比較的に高くなっている。また、装飾圧搾域５１に位置する第１及び第２装飾部２２，２３は、安定的に圧縮されることからよれることはなく、確実に所望の形状に賦型することができる。それにより、その輪郭形状が明瞭となり外部からの視認が容易となるので、所望の装飾効果を発揮することができる。特に、第１及び第２装飾部２２，２３は、第１及び第２エンドフラップ２８，２９やサイドフラップ３２などのシート部材のみから形成された部位に比して厚さ寸法の大きい芯材１３の存在領域に形成されているので、装飾模様がより立体的となり装飾効果に優れているといえる。   Thus, in the decorative compressed area 51, the total area of the compressed groove 20 having a linear pressure width (about 3 mm) as a unit width is smaller than other areas. A higher pressure is applied than the outer edge 21a of the outer peripheral portion 21 and the curved portion 24, and the density thereof is relatively high. Moreover, the 1st and 2nd decoration parts 22 and 23 located in the decoration pressing area 51 do not depend on being compressed stably, but can be shape | molded to a desired shape reliably. As a result, the contour shape becomes clear and visual recognition from the outside becomes easy, so that a desired decorative effect can be exhibited. In particular, the first and second decorative portions 22, 23 have a core material 13 having a large thickness compared to portions formed only from sheet members such as the first and second end flaps 28, 29 and the side flaps 32. Therefore, it can be said that the decorative pattern becomes more three-dimensional and excellent in the decorative effect.

なお、装飾効果を有する圧搾パターンは従来においても数多く存在するが、既述のとおり、本実施形態では、第１及び第２装飾部２２，２３は、ほぼ同形状を有し、それらが大小異なる大きさであって、かつ、縦軸Ｐに対して互いに傾いた状態で配置されていることによって、装飾圧搾域５１内の各線圧領域における圧搾条溝２０の面積が外端縁２１ａに位置する第１面積Ｓ１及び曲状部２４に位置する第２面積Ｓ２よりも小さくなっている。すなわち、任意の線圧領域内における第１装飾部２２と第２装飾部２３との総面積が所要以上に大きくならないように、それらの形状、傾きなどが調整されている。よって、従来の他の装飾効果を有する圧搾パターンでは発揮しえない前記の効果を奏するものといえる。   In addition, although many compression patterns which have a decoration effect exist conventionally, as above-mentioned, in this embodiment, the 1st and 2nd decoration parts 22 and 23 have substantially the same shape, and they differ in size. The size of the squeezing groove 20 in each linear pressure region in the decorative squeezing region 51 is positioned at the outer edge 21a by being arranged in a state of being inclined with respect to the longitudinal axis P. It is smaller than the first area S1 and the second area S2 located in the curved portion 24. That is, their shapes, inclinations, etc. are adjusted so that the total area of the first decorative portion 22 and the second decorative portion 23 in an arbitrary linear pressure region does not become larger than necessary. Therefore, it can be said that the above-described effect that cannot be exhibited by a compression pattern having other conventional decorative effects can be obtained.

また、かかる効果を奏するために、すなわち、第１及び第２装飾部２２，２３の輪郭形状をより明瞭にするために、例えば、エンボス部５７の凸部５６ｂを凸部５６ａよりも長くしたり、プレスローラー５４による下方に向かって負荷される力を大きくすることによってさらにその圧力を高めることも考えられる。しかし、前者の場合には、凸部５６ａが摩耗しやすくなり、エンボスロール５５の早期交換が必要になるおそれがあり、また、後者の場合には、トップシート１１の一部が破れて体液の漏れや外観を損ねるおそれがある。本発明では、各部における線圧領域Ｔ１〜Ｔ４内の圧搾条溝２０の面積を調整することによって、上記効果を奏するものであるから、かかる不利益を生じることはない。 In order to obtain such an effect, that is, in order to clarify the contour shape of the first and second decorative portions 22 and 23, for example, the convex portion 56b of the embossed portion 57 is made longer than the convex portion 56a. It is also conceivable to increase the pressure by increasing the force applied downward by the press roller 54. However, in the former case, the convex portion 56a is easily worn, premature replacement of the embossing roll 55 may become necessary and, in the latter case, torn portion of the topsheet 11 fluid Leakage and appearance may be damaged. In this invention, since the said effect is show | played by adjusting the area of the pressing groove 20 in the linear pressure area | regions T1-T4 in each part, this disadvantage does not arise.

本実施形態では、第１及び第２装飾部２２，２３の幅寸法が、外周部２１の幅寸法、曲状部２４の幅寸法よりも小さくなっている。このように、第１及び第２装飾部２２，２３の幅寸法が比較的に小さい場合には、第１及び第２装飾部２２，２３の輪郭形状をより明瞭にすることができるとともに、相対的に第１面積Ｓ１と第２面積Ｓ２を大きくすることができ、所要の圧接面積を確保することができる。   In the present embodiment, the width dimension of the first and second decorative parts 22 and 23 is smaller than the width dimension of the outer peripheral part 21 and the width dimension of the curved part 24. Thus, when the width dimension of the 1st and 2nd decoration parts 22 and 23 is comparatively small, while being able to make the outline shape of the 1st and 2nd decoration parts 22 and 23 clearer, relative In particular, the first area S1 and the second area S2 can be increased, and a required pressure contact area can be ensured.

本発明において、圧搾条溝２０が形成される前の吸液性コアの厚さ寸法は、１．０〜３．０ｍｍであって、低圧搾部１９ｃの厚さ寸法は、０．３〜０．５ｍｍである。低圧搾部１９ｃの厚さ寸法が０．３ｍｍ以下の場合には、圧搾条溝２０とそれが形成されていない領域との厚さ寸法の差が大きくなるので、製造時又は使用時においてトップシート１１が破れてしまうおそれがある。一方、低圧搾部１９ｃの厚さ寸法が０．５ｍｍ以上の場合には、低圧搾部１９ｃと高圧搾部１９ａ，１９ｂとの厚さ寸法の差が小さくなり、第１及び第２装飾部２２，２３の輪郭形状による装飾模様が不明瞭となるおそれがある。   In the present invention, the thickness dimension of the liquid-absorbent core before the compressed groove 20 is formed is 1.0 to 3.0 mm, and the thickness dimension of the low-pressure portion 19c is 0.3 to 0. .5 mm. When the thickness dimension of the low-pressure squeezed portion 19c is 0.3 mm or less, the difference in thickness dimension between the squeezed groove 20 and the region where it is not formed becomes large. 11 may be broken. On the other hand, when the thickness dimension of the low pressing part 19c is 0.5 mm or more, the difference in thickness dimension between the low pressing part 19c and the high pressing part 19a, 19b becomes small, and the first and second decorative parts 22 , 23 may cause an unclear decorative pattern.

また、高圧搾部１９ａ，１９ｂの厚さ寸法は、０．０１〜０．１ｍｍである。高圧搾部１９ａ，１９ｂの厚さ寸法が０．０１ｍｍ以下の場合には、製造時においてトップシート１１が破れてしまうおそれがあり、０．１以上の場合には、低圧搾部１９ｃとの厚さ寸法の差が小さくなり、体液を吸収したときに吸液性コアが浮き上がりやすくなるおそれがある。   Moreover, the thickness dimension of the high pressing parts 19a and 19b is 0.01-0.1 mm. When the thickness dimension of the high pressure parts 19a and 19b is 0.01 mm or less, the top sheet 11 may be torn during production. When the thickness dimension is 0.1 or more, the thickness with the low pressure part 19c is high. There is a risk that the difference in thickness is reduced and the absorbent core is likely to rise when the body fluid is absorbed.

＜吸収構造体４５の各部の厚さ寸法の測定方法＞
生理用ナプキン１０から吸収構造体４５を取り出して容器に入れて、容器内の液体窒素に含浸させた後、所要の大きさにカットしてサンプルする。その後、サンプルの温度が常温となるまで放置する。次に、電子顕微鏡（キーエンス社製ＶＥ７８００）を用いて５０倍の倍率でサンプルの各部の厚さ（ｍｍ）を測定し、吸収構造体４５の高圧搾部１９ａ，１９ｂ，低圧搾部１９ｃの厚さ寸法（ｍｍ）とした。 <Measuring method of thickness dimension of each part of absorbent structure 45>
The absorbent structure 45 is taken out from the sanitary napkin 10, placed in a container, impregnated with liquid nitrogen in the container, then cut into a required size and sampled. Then, it is left until the temperature of the sample reaches room temperature. Next, the thickness (mm) of each part of the sample was measured at a magnification of 50 times using an electron microscope (Keyence VE7800), and the thickness of the high-pressure parts 19a and 19b and the low-pressure part 19c of the absorption structure 45 was measured. It was set as the dimension (mm).

上記表１は、各種の圧搾パターンにおいて、プレスローラー５４による負荷１５ｋｇｆ／ｃｍ２の下、エンボスプレス工程５２において吸収構造体４５をプレスしたときの各線圧領域Ｋ１〜Ｋ５における圧搾条溝２０の面積（ｍｍ２）などを表わしたものである。具体的には、実施例１として、図１０（ａ）に示すように、第１装飾部２２の花びら状部６０，６１が横軸Ｑの方向（製造時における直交方向ＣＤ）とほぼ平行に位置している状態にあるもの、実施例２として、それらを約３０度時計回り方向に回転させた状態で配置したもの（図１０（ｂ））、実施例３として、さらにそれらを約１５度時計回り方向に回転させた状態で配置したもの（図１０（ｃ））の圧搾パターンを作成した。かかる実施例１〜３において、各線圧領域Ｋ１〜Ｋ５の「圧搾条溝２０の面積」、「第１装飾部２２の面積のみ」、「第２装飾部２３の面積のみ」を表１に記載した。 Table 1 shows the area of the compressed groove 20 in each linear pressure region K1 to K5 when the absorbent structure 45 is pressed in the embossing press step 52 under a load of 15 kgf / cm 2 by the press roller 54 in various pressing patterns. (Mm 2 ) and the like. Specifically, as Example 1, as shown in FIG. 10A, the petal-like parts 60 and 61 of the first decorative part 22 are substantially parallel to the direction of the horizontal axis Q (the orthogonal direction CD at the time of manufacture). In a state where they are positioned, as Example 2, they are arranged in a state where they are rotated by about 30 degrees clockwise (FIG. 10B), and as Example 3, they are further about 15 degrees. A squeezed pattern of the one arranged in a clockwise direction (FIG. 10C) was created. In Examples 1 to 3, the “area of the compressed groove 20”, “the area of the first decorative portion 22”, and “the area of the second decorative portion 23” of each linear pressure region K1 to K5 are shown in Table 1. did.

表１に示すとおり、線圧領域Ｋ２の外周部２１と第１装飾部２２との面積は、実施例１〜３のいずれの圧搾パターンであっても、外周部２１の外端縁２１ａにおける線圧領域Ｋ１の面積約４２ｍｍ２よりも小さくなっている。一方、線圧領域Ｋ３〜Ｋ５における第１及び第２装飾部２２，２３と外周部２１との総面積（圧搾条溝２０の総面積）は、圧搾パターンに応じて線圧領域Ｋ１の面積を超えることがあり、例えば、実施例１における線圧領域Ｋ４の圧搾条溝２０の面積、実施例２における線圧領域Ｋ３の圧搾条溝２０の面積、実施例３における線圧領域Ｋ３の圧搾条溝２０の面積はすべて４２ｍｍ２以上であって、本発明の上記効果を奏するものとはいえない。 As shown in Table 1, the area of the outer peripheral portion 21 and the first decorative portion 22 of the linear pressure region K2 is a line at the outer edge 21a of the outer peripheral portion 21 regardless of the compression pattern of each of the first to third embodiments. The area of the pressure region K1 is smaller than about 42 mm 2 . On the other hand, the total area of the first and second decorative portions 22 and 23 and the outer peripheral portion 21 in the linear pressure regions K3 to K5 (total area of the compressed groove 20) is the area of the linear pressure region K1 according to the compression pattern. For example, the area of the compressed groove 20 of the linear pressure region K4 in Example 1, the area of the compressed groove 20 of the linear pressure region K3 in Example 2, the compressed line of the linear pressure region K3 in Example 3 The areas of the grooves 20 are all 42 mm 2 or more, and it cannot be said that the above effects of the present invention are exhibited.

しかし、任意の圧搾パターンにおいて、線圧領域Ｋ１の圧搾条溝２０の面積よりも大きい面積を有する場合であっても、他の圧搾パターンにおいては、線圧領域Ｋ１の圧搾条溝２０の面積以下となる場合があり、例えば、実施例１の線圧領域Ｋ４ではその面積が約５５ｍｍ２であるところ、実施例２では、その面積が約４１ｍｍ２であって、線圧領域Ｋ１における圧搾条溝２０の面積よりも小さくなっている。 However, even if it is a case where it has a larger area than the area of the pressing groove 20 of the linear pressure region K1 in an arbitrary pressing pattern, in other pressing patterns, it is equal to or less than the area of the pressing groove 20 of the linear pressure region K1. For example, in the linear pressure region K4 of Example 1, the area is about 55 mm 2 , and in Example 2, the area is about 41 mm 2 , and the compressed groove in the linear pressure region K1 The area is smaller than 20.

以上のように、所与の形状を有する第１装飾部２２及び／または第２装飾部２３を縦軸Ｐ及び／または横軸Ｑに関して任意の角度に傾けることによって、装飾圧搾域５１内の線圧領域における圧搾条溝２０の面積を自由に調整することができ、本発明の効果を奏するための要件である、「線圧領域Ｋ１の圧搾条溝２０の面積＞装飾圧搾域５１における各線圧領域Ｋ２〜５の面積」という条件を満たす圧搾パターンを自由に選択することができる。   As described above, by inclining the first decorative portion 22 and / or the second decorative portion 23 having a given shape at an arbitrary angle with respect to the vertical axis P and / or the horizontal axis Q, a line in the decorative compressed region 51 is obtained.
