　図１から図６を参照して、実施形態に係る吸収性物品１及びこの吸収性物品１を包装シート７０によって包装した吸収性物品の包装体１００について説明する。図１は、吸収性物品の包装体の肌当接面側から見た平面図であり、図２は、吸収性物品の包装体の背面図である。図３は、図１に示すＡ－Ａ断面の模式断面図である。吸収性物品の包装体１００は、吸収性物品１と、この吸収性物品１を包装する包装シート７０と、を有する。本実施形態に係る吸収性物品１は、例えば、生理用ナプキンである。 1 to 6, an absorbent article 1 according to the embodiment and an absorbent article package 100 in which the absorbent article 1 is packaged by a packaging sheet 70 will be described. FIG. 1 is a plan view seen from the skin contact surface side of the absorbent article package, and FIG. 2 is a rear view of the absorbent article package. FIG. 3 is a schematic cross-sectional view taken along the line AA shown in FIG. The absorbent article packaging body 100 includes an absorbent article 1 and a packaging sheet 70 for packaging the absorbent article 1. The absorbent article 1 according to the present embodiment is, for example, a sanitary napkin.
　吸収性物品の包装体１００は、包装シート７０上に吸収性物品１が配置された状態で包装シート７０と吸収性物品１とが折り畳まれることにより、吸収性物品１が個別に包装される。図１及び図２は、包装シート７０によって吸収性物品１を個別に包装した後、吸収性物品１を開いた展開状態を示している。この吸収性物品１の包装態様については、後述にて詳細に説明する。 The absorbent article packaging body 100 is packaged individually by folding the packaging sheet 70 and the absorbent article 1 in a state where the absorbent article 1 is disposed on the packaging sheet 70. 1 and 2 show a developed state in which the absorbent article 1 is opened after individually packaging the absorbent article 1 with the packaging sheet 70. The packaging mode of the absorbent article 1 will be described in detail later.
　吸収性物品１は、液体を透過する液透過性の表面シート１０、液体を透過しない液不透過性の裏面シート２０、及び吸収体３０を有する吸収性本体１Ａと、吸収性本体１Ａよりも幅方向外側に延出するフラップ部１Ｂと、を有する。吸収性本体１Ａは、表面シート１０、裏面シート２０及び吸収体３０が積層された部分であり、フラップ部１Ｂは、吸収体３０よりも幅方向外側の部分である。 The absorbent article 1 includes a liquid permeable top sheet 10 that transmits liquid, a liquid impermeable back sheet 20 that does not transmit liquid, and an absorbent main body 1A having an absorbent body 30 and a width wider than the absorbent main body 1A. And a flap portion 1B extending outward in the direction. The absorbent main body 1 </ b> A is a portion where the topsheet 10, the backsheet 20, and the absorber 30 are laminated, and the flap portion 1 </ b> B is a portion on the outer side in the width direction than the absorber 30.
　吸収体３０は、表面シート１０と裏面シート２０との間に配設される。従って、吸収体３０は、図１において破線で示される。吸収体３０は、吸収性物品１の長手方向Ｌ及び幅方向Ｗにおける中央部分に配設される。 The absorber 30 is disposed between the top sheet 10 and the back sheet 20. Therefore, the absorber 30 is shown with a broken line in FIG. The absorbent body 30 is disposed at the central portion in the longitudinal direction L and the width direction W of the absorbent article 1.
　フラップ部１Ｂは、着用者の***口に当接する***口当接領域の幅方向外側に配置されたウイングフラップ部４３と、ウイングフラップ部４３よりも後方に配置されたヒップフラップ部４４と、を備える。更に、吸収性物品１は、幅方向Ｗにおいて吸収体３０の外側に設けられるサイドシート４１を備える。 The flap portion 1B includes a wing flap portion 43 disposed on the outer side in the width direction of the excretion opening contact region that contacts the excretion opening of the wearer, and a hip flap portion 44 disposed rearward of the wing flap portion 43. Prepare. Further, the absorbent article 1 includes a side sheet 41 provided outside the absorbent body 30 in the width direction W.
　なお、***口当接領域は、吸収性物品１において着用者の膣口に当接する領域であり、例えば、着用者の下着に吸収性物品１が着用される際に、下着の２つの足回り開口の間に配置される領域である。また、***口当接領域の中心とは、着用者の***口が当接する領域の長手方向及び幅方向の中心である。例えば、ウイング部を有する吸収性物品においては、ウイング部の長手方向の中心が、***口当接領域の長手方向の中心となる。また、ウイング部を有しない吸収性物品においては、吸収体の幅方向の長さ寸法が最も短い位置が、***口当接領域の長手方向の中心となる。 The excretory opening contact region is a region that contacts the vaginal opening of the wearer in the absorbent article 1, and, for example, when the absorbent article 1 is worn on the wearer's underwear, It is an area | region arrange | positioned between opening. The center of the excretion opening contact area is the center in the longitudinal direction and the width direction of the area where the wearer's excretion opening contacts. For example, in an absorbent article having a wing portion, the center in the longitudinal direction of the wing portion is the center in the longitudinal direction of the excretory opening contact region. Moreover, in the absorbent article which does not have a wing part, the position where the length dimension of the width direction of an absorber is the shortest becomes the center of the longitudinal direction of an excretion opening | mouth contact | abutting area | region.
　表面シート１０は、体液等の液体を透過する液透過性のシートである。表面シート１０は、少なくとも吸収体３０の表面を覆う。表面シート１０は、不織布、織布、有孔プラスチックシート、メッシュシート等、液体を透過する構造のシート状の材料であれば、特に限定されない。織布や不織布の素材としては、天然繊維、化学繊維のいずれも使用できる。 The top sheet 10 is a liquid-permeable sheet that transmits liquid such as body fluid. The top sheet 10 covers at least the surface of the absorber 30. The top sheet 10 is not particularly limited as long as it is a sheet-like material having a structure that allows liquid to permeate, such as a nonwoven fabric, a woven fabric, a perforated plastic sheet, and a mesh sheet. Either natural fibers or chemical fibers can be used as the woven or non-woven material.
　また、表面シート１０上の液伝いを抑制するために、表面シート１０の肌当接側の面に凹凸加工を施してもよいし、不織布からなる表面シート１０の成形時にエアーを当てることによって、不織布に目付のむらを形成してもよい。 Moreover, in order to suppress the liquid transfer on the top sheet 10, the surface of the top sheet 10 on the skin contact side may be roughened, or by applying air when molding the top sheet 10 made of a nonwoven fabric, You may form the unevenness of a fabric weight in a nonwoven fabric.
　また、表面シート１０と吸収体３０との間に、表面シート１０側から吸収体３０側へ体液を引き込むためのセカンドシート１１が設けられている（図３参照）。セカンドシート１１は、幅方向において表面シートよりも短く構成されている。図６にセカンドシートの幅方向端部１１Ｅと表面シートの幅方向端部１０Ｅとを図示する。セカンドシート１１は、熱可塑性繊維を含む不織布又はテッシュによって構成されている。セカンドシートの肌当接側の面には、印刷が施された着色部１２（図１参照）が設けられている。着用者は、表面シート１０を介して着色部１２を視認できるように構成されている。 Further, a second sheet 11 for drawing body fluid from the surface sheet 10 side to the absorber 30 side is provided between the surface sheet 10 and the absorber 30 (see FIG. 3). The second sheet 11 is configured to be shorter than the top sheet in the width direction. FIG. 6 illustrates the width direction end portion 11E of the second sheet and the width direction end portion 10E of the top sheet. The second sheet 11 is composed of a nonwoven fabric or a tissue containing thermoplastic fibers. A colored portion 12 (see FIG. 1) on which printing is performed is provided on the surface of the second sheet on the skin contact side. The wearer is configured to be able to visually recognize the colored portion 12 through the top sheet 10.
　なお、着色部１２は、表面シート１０の肌当接側以外の面に設けられていることが望ましく、セカンドシート１１の非肌当接側面に配置されていてもよいし、表面シートの非肌当接面に配置されていてもよい。例えば、着色部１２が表面シート１０の肌当接側面に配置されていると、肌に対して表面シート１０が擦れた場合に、着色剤が肌に付着するおそれがある。しかし、表面シート１０の肌当接面以外の面に着色部１２が設けられていることにより、着色剤が肌に付着するリスクを低減できる。また、より好ましくは、表面シート１０の肌当接面に着色部を設けると、着色部が色抜けするおそれがあるため、セカンドシート１１に着色部１２を設けることが望ましい。 The colored portion 12 is desirably provided on a surface other than the skin contact side of the top sheet 10, and may be disposed on the non-skin contact side surface of the second sheet 11, or may be disposed on the non-skin of the top sheet. You may arrange | position to the contact surface. For example, when the colored portion 12 is disposed on the skin contact side surface of the topsheet 10, the colorant may adhere to the skin when the topsheet 10 rubs against the skin. However, since the colored portion 12 is provided on a surface other than the skin contact surface of the topsheet 10, the risk that the colorant adheres to the skin can be reduced. More preferably, when the colored portion is provided on the skin contact surface of the top sheet 10, the colored portion may lose color, and thus it is desirable to provide the colored portion 12 on the second sheet 11.
　一方、着色部１２の視認性を確保するためには、着色部よりも肌当接面側に配置されるシート材が少ないことが望ましく、セカンドシートの非肌当接面側よりも表面シートの肌当接面側に設けることが望ましい。なお、セカンドシートを有しない吸収性物品においては、表面シートに着色部を設けることが好ましい。 On the other hand, in order to ensure the visibility of the colored portion 12, it is desirable that the sheet material disposed on the skin contact surface side is smaller than the colored portion, and the surface sheet is less than the non-skin contact surface side of the second sheet. It is desirable to provide on the skin contact surface side. In addition, in the absorbent article which does not have a second sheet | seat, it is preferable to provide a colored part in a surface sheet.
　また、セカンドシート１１の密度は、表面シート１０の密度よりも高く構成されていることが望ましい。セカンドシートが表面シートよりも高密度であって繊維の目が詰まっているので、着色部１２をより細かく配置できる。また、セカンドシートが表面シートよりも高い密度であるため、体液の引き込み性を高めることができる。 Further, it is desirable that the density of the second sheet 11 is higher than that of the top sheet 10. Since the second sheet has a higher density than the top sheet and the fibers are clogged, the colored portions 12 can be arranged more finely. In addition, since the second sheet has a higher density than the top sheet, it is possible to improve the body fluid drawability.
　着色部１２は、フレキソ印刷、グラビア印刷、オフセット印刷、インクジェット印刷等、種々の印刷方法によって形成することができる。また、着色部の着色剤は、例えば、水性インクや油性インクを用いることができ、特に制限されない。図１に示す平面視における表面シートの面積に対する着色部の面積は、例えば、3%～50%とすることができる。各着色部１２の長手方向の長さ及び幅方向の長さは、5mm～30mmが好ましい。着色部１２の長手方向の間隔及び幅方向の間隔は、10mm～60mmが好ましい。着色剤の目付は、未乾燥重量において10g/ｍ２とすることができる。 The colored portion 12 can be formed by various printing methods such as flexographic printing, gravure printing, offset printing, and inkjet printing. In addition, for example, water-based ink or oil-based ink can be used as the colorant of the colored portion, and is not particularly limited. The area of the colored portion relative to the area of the surface sheet in plan view shown in FIG. 1 can be, for example, 3% to 50%. The length in the longitudinal direction and the length in the width direction of each colored portion 12 are preferably 5 mm to 30 mm. The interval in the longitudinal direction and the interval in the width direction of the colored portion 12 is preferably 10 mm to 60 mm. The basis weight of the colorant can be 10 g / m 2 in the undried weight.
　また、着色部１２は、１色で着色されていてもよいし、２色以上で着色されていてもよい。また、着色部１２は、インキの濃度による濃淡模様が形成されていてもよい。個々の着色部において濃淡模様が形成されていてもよいし、複数の同一デザインの着色部において濃淡が異なるように構成し、複数の着色部の濃淡の違いによって濃淡模様が形成されていてもよい。複数の着色部において濃淡を異ならせることにより、遠近感によってデザインに立体感を付与することができる。 Moreover, the coloring part 12 may be colored with one color or may be colored with two or more colors. Moreover, the coloring part 12 may be formed with a shading pattern depending on the density of the ink. A shading pattern may be formed in each colored portion, or the shading pattern may be formed by a difference in shading in the plurality of colored portions, with the shading being different in a plurality of colored portions of the same design. . By varying the shade in the plurality of colored portions, it is possible to give a stereoscopic effect to the design by perspective.
　更に、着色部は、吸収性物品の前側及び後側に位置する着色部の色が薄く、かつ長手方向中央に位置する着色部の色が濃くなるように構成してもよい。視覚的効果によって、着用者は、比較的濃い着色部を有する中央領域の厚みを厚く感じ、比較的薄い着色部を有する前側及び後側の厚みを薄く感じ易くなる。実際の製品の厚みを厚くすることなく、視覚的効果によって厚みを厚く感じさせることにより、使用時の違和感を抑制しつつ、吸収性能の不安を払拭することができる。 Furthermore, the colored portion may be configured such that the color of the colored portion located on the front side and the rear side of the absorbent article is light and the color of the colored portion located in the center in the longitudinal direction is dark. The visual effect makes it easier for the wearer to feel the thickness of the central region having a relatively dark colored portion and to feel the thickness of the front side and the rear side having a relatively thin colored portion thin. By making the thickness feel thicker by visual effect without increasing the thickness of the actual product, it is possible to eliminate anxiety in absorption performance while suppressing a sense of discomfort during use.
　裏面シート２０は、表面シート１０の長さと略同一の長さを有する。裏面シート２０は、ポリエチレン、ポリプロピレン等を主体としたフィルム、通気性の樹脂フィルム、スパンボンド、又はスパンレース等の不織布に通気性の樹脂フィルムが接合されたシートなどを用いることができる。裏面シート２０は、着用時の違和感を生じさせない程度の柔軟性を有する材料とすることが好ましい。本実施の形態の裏面シート２０は、液不透過性のポリエチレンのフィルムによって構成されている。 The back sheet 20 has substantially the same length as the top sheet 10. The back sheet 20 may be a film mainly composed of polyethylene, polypropylene, or the like, a breathable resin film, a sheet obtained by bonding a breathable resin film to a nonwoven fabric such as spunbond or spunlace. The back sheet 20 is preferably made of a material having flexibility that does not cause a sense of incongruity when worn. The back sheet 20 of the present embodiment is constituted by a liquid-impermeable polyethylene film.
　吸収体３０は、テッシュ又は不織布からなる吸収シート３１と、吸収シート３１よりも肌当接側に配置され、パルプが積層された吸収コア３２と、を含む。吸収コア３２は、吸収シート３１の肌当接側の面に当接した下側吸収コア３２Ａと、下側吸収コア３２Ａよりも肌当接側の面に当接した上側吸収コア３２Ｂと、を有する。 The absorbent body 30 includes an absorbent sheet 31 made of a tissue or a non-woven fabric, and an absorbent core 32 disposed on the skin contact side with respect to the absorbent sheet 31 and laminated with pulp. The absorbent core 32 includes a lower absorbent core 32A that is in contact with the skin contact side surface of the absorbent sheet 31, and an upper absorbent core 32B that is in contact with the skin contact side surface of the lower absorbent core 32A. Have.
　吸収シート３１は、テッシュ又は不織布によって形成することができる。吸収シートを構成する不織布としては、熱可塑性繊維からなる不織布であって、親水性処理を施した不織布や、親水性繊維からなる不織布を用いることができる。また、吸収シートを構成する不織布として、親水性繊維又は粉体をエアレイド法によってシート状に成形したエアレイドシートを用いることも可能となる。 The absorbent sheet 31 can be formed of a tissue or a nonwoven fabric. As a nonwoven fabric which comprises an absorption sheet, it is a nonwoven fabric which consists of thermoplastic fibers, Comprising: The nonwoven fabric which performed the hydrophilic process and the nonwoven fabric which consists of hydrophilic fibers can be used. In addition, an airlaid sheet obtained by forming hydrophilic fibers or powder into a sheet by an airlaid method can be used as the nonwoven fabric constituting the absorbent sheet.
　吸収コア３２は、吸収シート３１よりも長手方向Ｌ及び幅方向Ｗにおいて小さい。また、上側吸収コア３２Ｂは、下側吸収コア３２Ａよりも長手方向Ｌ及び幅方向Ｗにおいて小さい。上側吸収コア３２Ｂは、下側吸収コア３２Ａよりも吸収材料の目付が高く構成されており、***口当接領域を含む中央領域に配置されている。上側吸収コア３２Ｂは、図１に示す平面視において、表面シート１０、セカンドシート１１、及び吸収体３０が厚み方向に圧縮された第１圧搾部２３によって囲まれた第１領域Ｒ１に設けられている。なお、本実施の形態では、上側吸収コア３２Ｂと下側吸収コア３２Ａとが一体化されている。 The absorbent core 32 is smaller than the absorbent sheet 31 in the longitudinal direction L and the width direction W. The upper absorbent core 32B is smaller in the longitudinal direction L and the width direction W than the lower absorbent core 32A. The upper absorbent core 32B is configured so that the weight of the absorbent material is higher than that of the lower absorbent core 32A, and is disposed in the central region including the excretory opening contact region. The upper absorbent core 32B is provided in the first region R1 surrounded by the first pressing portion 23 in which the topsheet 10, the second sheet 11, and the absorber 30 are compressed in the thickness direction in the plan view shown in FIG. Yes. In the present embodiment, the upper absorbent core 32B and the lower absorbent core 32A are integrated.
　上側吸収コア３２Ｂと下側吸収コア３２Ａは、別個に構成されていてもよいし、一体化されていてもよい。本実施の形態に係る吸収コア３２は、上側吸収コア３２Ｂと下側吸収コア３２Ａとが一体化して形成されている。吸収シート３１と吸収コア３２とが別体によって構成される場合には、ホットメルト型接着剤等の接着剤によって貼り合わされていてもよい。 The upper absorbent core 32B and the lower absorbent core 32A may be configured separately or may be integrated. The absorbent core 32 according to the present embodiment is formed by integrating an upper absorbent core 32B and a lower absorbent core 32A. When the absorbent sheet 31 and the absorbent core 32 are configured separately, they may be bonded together with an adhesive such as a hot melt adhesive.
　また、吸収体のセカンドシート１１又は表面シート１０との肌当接面には、柔軟剤（トリート剤）を含む粉砕パルプによって構成することが望ましい。一般的に、体液は、親水性の低い部分から親水性の高い部分に移行し易い。例えば、吸収体３０の肌当接面側（セカンドシート１１又は表面シート１０との肌当接面）に柔軟剤を含む粉砕パルプを配置すると、吸収体の肌当接面側の親水性が低くなり、吸収体の肌当接面側から衣服当接面側に向かって親水性が高くなる親水勾配が形成される。よって、表面シート側から吸収体に到達した体液が表面シート側から裏面シート側に移行し易くなり、体液の引き込み性を高め、表面シートをドライな状態に保ちやすくなる。 Further, it is desirable that the skin contact surface with the second sheet 11 or the top sheet 10 of the absorbent body is made of pulverized pulp containing a softening agent (treating agent). In general, the body fluid tends to move from a portion having low hydrophilicity to a portion having high hydrophilicity. For example, when pulverized pulp containing a softening agent is disposed on the skin contact surface side of the absorbent body 30 (skin contact surface with the second sheet 11 or the top sheet 10), the hydrophilicity of the absorbent body on the skin contact surface side is low. Thus, a hydrophilic gradient is formed in which the hydrophilicity increases from the skin contact surface side of the absorbent body toward the clothing contact surface side. Therefore, the bodily fluid that has reached the absorber from the top sheet side is likely to move from the top sheet side to the back sheet side, the body fluid is easily drawn, and the top sheet is easily kept dry.
　表面シート１０、セカンドシート１１、吸収体３０、裏面シート２０は、それぞれの層間分離を防止するためにも接合されていることが好ましい。これらの接合は、エンボス加工、超音波、ホットメルト型接着剤等を単独もしくは組み合わせて使用することが可能である。また、着用時における吸収体の型崩れやヨレを防止したり、吸収体の厚みを調整したりするために、吸収体にエンボス加工を施してもよい。 It is preferable that the top sheet 10, the second sheet 11, the absorber 30, and the back sheet 20 are bonded to prevent the respective layers from being separated from each other. These joints can be used alone or in combination with embossing, ultrasonic waves, hot melt adhesives, and the like. Further, the absorber may be embossed in order to prevent the absorber from being deformed or twisted when worn, or to adjust the thickness of the absorber.
　サイドシート４１は、表面シート１０の両側に配設される。サイドシート４１は、表面シート１０と同様の材料から選ぶことができる。但し、サイドシート４１を乗り越えて吸収性物品１外方へ経血が流れることを防止するためには、疎水性又は撥水性を有することが好ましい。具体的には、スパンボンド不織布やＳＭＳ不織布などが挙げられ、特に、こすれによる肌への刺激を低減するためにはエアースルー不織布が好ましい。 The side sheet 41 is disposed on both sides of the top sheet 10. The side sheet 41 can be selected from the same material as the top sheet 10. However, in order to prevent menstrual blood from flowing over the side sheet 41 to the outside of the absorbent article 1, it is preferable to have hydrophobicity or water repellency. Specific examples include spunbond nonwoven fabrics and SMS nonwoven fabrics. In particular, an air-through nonwoven fabric is preferable in order to reduce irritation to the skin due to rubbing.
　サイドシート４１は、吸収体３０の側縁の一部及びフラップ部１Ｂを覆う。サイドシート４１の幅方向における内側端部４１Ｅは、後述する第１長手折り目ＦＬ１及び第２長手折り目ＦＬ２よりも幅方向外側において、第１長手折り目ＦＬ１及び第２長手折り目ＦＬ２に隣接して配置されている。 The side sheet 41 covers a part of the side edge of the absorber 30 and the flap portion 1B. The inner end portion 41E in the width direction of the side seat 41 is disposed adjacent to the first longitudinal fold FL1 and the second longitudinal fold FL2 outside the first longitudinal fold FL1 and the second longitudinal fold FL2, which will be described later, on the outer side in the width direction. ing.
　吸収性物品１では、表面シート１０、サイドシート４１及び裏面シート２０の周縁が接合されて、吸収体３０が内封される。表面シート１０と裏面シート２０との接合方法としては、ヒートエンボス加工、超音波、又はホットメルト型接着剤のいずれか一つ、又は複数を組み合わせることが可能である。 In the absorbent article 1, the peripheral edges of the top sheet 10, the side sheet 41, and the back sheet 20 are joined, and the absorbent body 30 is enclosed. As a method for joining the top sheet 10 and the back sheet 20, any one or a combination of heat embossing, ultrasonic waves, or hot melt adhesive can be used.
　裏面シート２０において下着と接触する表面には、粘着剤が塗布された粘着領域が複数設けられている。粘着領域は、吸収性本体１Ａの非肌当接側の面に設けられた本体粘着領域５１（図３参照）と、フラップ部１Ｂの非肌当接側の面に設けられたフラップ粘着領域５２（図３参照）と、を有する。なお、本実施の形態に係るフラップ粘着領域５２は、ウイングフラップ部４３のみに設けられているが、ヒップフラップ部４４に設けられていてもよい。 A plurality of adhesive regions coated with an adhesive are provided on the surface of the back sheet 20 that comes into contact with the undergarment. The adhesive region includes a main body adhesive region 51 (see FIG. 3) provided on the non-skin contact side surface of the absorbent main body 1A and a flap adhesive region 52 provided on the non-skin contact side surface of the flap portion 1B. (See FIG. 3). In addition, although the flap adhesion area | region 52 which concerns on this Embodiment is provided only in the wing flap part 43, you may be provided in the hip flap part 44. FIG.
　使用前の状態では、本体粘着領域５１は、離型シートとしての本体シート６１によって覆われ、フラップ粘着領域５２は、離型シートとしてのフラップシート６２によって覆われている。本体シート６１及びフラップシート６２によって、使用前に接着剤が劣化するのを防止している。 In the state before use, the main body adhesive region 51 is covered with a main body sheet 61 as a release sheet, and the flap adhesive region 52 is covered with a flap sheet 62 as a release sheet. The main body sheet 61 and the flap sheet 62 prevent the adhesive from deteriorating before use.
　本体シート６１は、本体粘着領域５１と包装シート７０との間に配置されている。本体シート６１の本体粘着領域５１側の面には、離型処理が施されており、本体粘着領域５１と離間可能に構成されている。フラップシート６２のフラップ粘着領域５２側の面には、離型処理が施されており、フラップ粘着領域５２と離間可能に構成されている。 The main body sheet 61 is disposed between the main body adhesive region 51 and the packaging sheet 70. The surface of the main body sheet 61 on the main body adhesive region 51 side is subjected to a mold release process and is configured to be separated from the main body adhesive region 51. The surface of the flap sheet 62 on the side of the flap adhesive region 52 is subjected to a mold release process, and is configured to be separated from the flap adhesive region 52.
　本体シート６１及びフラップシート６２は、それぞれ、接着剤を介して包装シート７０に接着されている。包装シート７０の本体シート及びフラップシート側の面には、本体シート６１を接着する接着剤が塗布された本体接着領域６５と、フラップシート６２を接着する接着剤が塗布されたフラップ接着領域６６と、がそれぞれ複数設けられている。 The main body sheet 61 and the flap sheet 62 are each bonded to the packaging sheet 70 via an adhesive. The main body sheet and the flap sheet side surface of the packaging sheet 70 have a main body bonding area 65 to which an adhesive for bonding the main body sheet 61 is applied, and a flap bonding area 66 to which an adhesive for bonding the flap sheet 62 is applied. Are provided in plural.
　本体接着領域６５は、長手方向に延びる筋状であり、本体粘着領域５１よりも短い幅で、本体粘着領域５１よりも多数並んで配置されている。また、フラップ接着領域６６は、フラップ粘着領域５２よりも短い幅で、フラップ粘着領域５２よりも多数並んで配置されている。 The main body adhesion region 65 has a streak shape extending in the longitudinal direction, has a width shorter than the main body adhesion region 51, and is arranged side by side more than the main body adhesion region 51. In addition, the flap adhesion region 66 has a shorter width than the flap adhesion region 52 and is arranged side by side more than the flap adhesion region 52.
　包装シート７０は、吸収性物品１を個別に包装する。包装シート７０は、吸収性物品１の裏面シート２０側において吸収性物品１と対向する対向面７１と、吸収性物品１を収容した状態で外側に位置する非対向面７２と、を有する。 The packaging sheet 70 wraps the absorbent article 1 individually. The packaging sheet 70 has a facing surface 71 that faces the absorbent article 1 on the back sheet 20 side of the absorbent article 1 and a non-facing surface 72 that is positioned outside in a state in which the absorbent article 1 is accommodated.
　なお、包装シート７０は、質感向上等の目的のために包装シート７０の表面に丸点エンボスや梨地エンボスのような表面加工が施されていてもよい。包装シート７０の材質としては、例えば、ポリエチレンやポリプロピレン、ポリエステル等のプラスチックフィルムやナイロンフィルムなどの各種フィルム、不織布をラミネートさせたフィルム等が挙げられる。 Note that the packaging sheet 70 may be subjected to a surface treatment such as round dot embossing or satin embossing on the surface of the packaging sheet 70 for the purpose of improving the texture or the like. Examples of the material of the packaging sheet 70 include plastic films such as polyethylene, polypropylene, and polyester, various films such as nylon films, films laminated with nonwoven fabrics, and the like.
　本体シート６１及びフラップシート６２は、包装シート７０に接着されているため、包装シート７０から吸収性物品１を離間させると、包装シート７０と吸収性物品１から離間し、本体粘着領域５１及びフラップ粘着領域５２が露出する。 Since the main body sheet 61 and the flap sheet 62 are bonded to the packaging sheet 70, when the absorbent article 1 is separated from the packaging sheet 70, the main body sheet 61 and the flap sheet 62 are separated from the packaging sheet 70 and the absorbent article 1. The adhesive region 52 is exposed.
　なお、粘着剤及び接着剤は、例えば、ホットメルト型接着剤を用いることができる。また、本体シート及びフラップシートは、粘着剤の粘着力を低下させることなく剥離可能にする離型処理が施された紙，フィルム，不織布によって構成することができる。例えば、ポリエチレンテレフタレート又はポリプロピレンフィルムにシリコーン樹脂塗工したシートや、紙にシリコーン樹脂塗工したポリエチレンフィルムをラミネートしたシートを、本体シート６１及びフラップシート６２として用いることができる。 In addition, for the pressure-sensitive adhesive and the adhesive, for example, a hot melt adhesive can be used. In addition, the main body sheet and the flap sheet can be constituted by paper, film, or nonwoven fabric that has been subjected to a release treatment that enables peeling without reducing the adhesive strength of the adhesive. For example, a sheet obtained by coating a polyethylene terephthalate or polypropylene film with a silicone resin or a sheet obtained by laminating a polyethylene film coated with a silicone resin on paper can be used as the main body sheet 61 and the flap sheet 62.
　このように構成された吸収性物品１及び包装シート７０は、幅方向Ｗ及び長手方向Ｌに沿った所定の折り位置において、吸収性物品１の表面シート１０を内側にして折り畳まれる。吸収性物品１が折り畳まれた状態で、包装シート７０の長手方向Ｌにおける一方の端部が包装シート７０に貼着される。包装シート７０の端部は、粘着テープ７５によって包装シート７０の一部と貼着される。 The absorbent article 1 and the packaging sheet 70 configured in this manner are folded at a predetermined folding position along the width direction W and the longitudinal direction L with the surface sheet 10 of the absorbent article 1 inside. In a state where the absorbent article 1 is folded, one end portion in the longitudinal direction L of the packaging sheet 70 is adhered to the packaging sheet 70. The edge part of the packaging sheet 70 is stuck to a part of the packaging sheet 70 by the adhesive tape 75.
　また、吸収体の目付及び密度は、例えば、以下の測定方法によって測定することができる。包装体によって包装された吸収性物品においては包装体を開封し、折り畳まれた吸収性物品を展開して、目付及び密度を測定する部分の厚み及び面積を測定する。次いで、目付及び密度を測定する部分を吸収性物品から切り出し、切り出した部分の重量を測定する。次いで、切り出した部分から表面シート及び裏面シート等、吸収体以外の部分を取り除き、吸収体の重量を測定する。吸収体の重量と、目付及び密度を測定する部分の面積とに基づいて目付を算出する。目付及び厚みに基づいて、密度を算出する。 Further, the basis weight and density of the absorber can be measured, for example, by the following measuring method. In the absorbent article packaged by the packaging body, the packaging body is opened, the folded absorbent article is developed, and the thickness and area of the portion where the basis weight and density are measured are measured. Subsequently, the part which measures a fabric weight and a density is cut out from an absorbent article, and the weight of the cut-out part is measured. Next, parts other than the absorber, such as the top sheet and the back sheet, are removed from the cut out part, and the weight of the absorber is measured. The basis weight is calculated based on the weight of the absorbent body and the area of the portion where the basis weight and density are measured. The density is calculated based on the basis weight and thickness.
　なお、厚みは、以下のような測定方法によって測定することができる。具体的には、サンプルの吸収性物品を、液体窒素に含浸させて凍結させた後、剃刀でカットし、常温に戻した後、電子顕微鏡（例えば、キーエンス社ＶＥ７８００）を用いて、５０倍の倍率で測定する。ここで、サンプルの吸収性物品を凍結させる理由は、カット時の圧縮により厚みが変動するのを防ぐためである。 The thickness can be measured by the following measuring method. Specifically, after the sample absorbent article was impregnated with liquid nitrogen and frozen, it was cut with a razor and returned to room temperature, and then it was magnified 50 times using an electron microscope (for example, KEYENCE VE7800). Measure with magnification. Here, the reason why the absorbent article of the sample is frozen is to prevent the thickness from fluctuating due to compression during cutting.
　ここで、上述のセカンドシート１１の目付、密度及び厚みについても、同様の方法で測定することができる。 Here, the basis weight, density, and thickness of the second sheet 11 can be measured by the same method.
　次に、このように構成された吸収性物品１の製造方法の一部について説明する。なお、説明しない方法については、既存の方法を用いることができる。吸収性物品の製造方法は、第１ステップとして、表面シート生成工程を行う。具体的には、表面シートとサイドシート４１，４２とを、例えば熱溶着によって接着し、その後、後述する第３圧搾部２５を形成する。 Next, a part of the manufacturing method of the absorbent article 1 configured as described above will be described. In addition, about the method which is not demonstrated, the existing method can be used. The manufacturing method of an absorbent article performs a surface sheet production | generation process as a 1st step. Specifically, the top sheet and the side sheets 41 and 42 are bonded to each other by, for example, heat welding, and then a third pressing portion 25 described later is formed.
　第２ステップとして、吸収体成型工程を行う。具体的には、成型ドラムによって吸収体の材料となるパルプを成型して吸収体３０を成型する。なお、第１ステップ及び第２ステップの製造工程は、異なる順序であってもよい。 As the second step, an absorber molding process is performed. Specifically, the absorber 30 is formed by molding pulp as a material of the absorber with a molding drum. Note that the manufacturing steps of the first step and the second step may be in different orders.
　第３ステップにおいて、接合工程を行う。具体的には、第１ステップにおいて接合した表面シート及びサイドシートと、第２ステップにおいて成型した吸収体と、を接合する接合工程を行う。 In the third step, a joining process is performed. Specifically, the joining process of joining the top sheet and the side sheet joined in the first step and the absorbent body molded in the second step is performed.
　第４ステップにおいて、圧搾工程を行う。具体的には、吸収体３０と表面シート１０とを厚み方向に圧縮し、後述する第１圧搾部２３及び第２圧搾部２４等を形成する。 In the fourth step, a pressing process is performed. Specifically, the absorber 30 and the topsheet 10 are compressed in the thickness direction to form a first squeezing part 23 and a second squeezing part 24, which will be described later.
　第５ステップにおいて、裏面シート接合工程を行う。具体的には、圧搾部を形成した吸収体及び表面シート等と、裏面シートとを接合する。裏面シートを接合した後、接着剤を塗布する工程を備える。上記の工程により、本実施の形態に係る吸収性物品を製造することができる。 In the fifth step, a back sheet joining process is performed. Specifically, the absorber, the top sheet, and the like that have formed the compressed parts are joined to the back sheet. After joining the back sheet, a step of applying an adhesive is provided. The absorbent article which concerns on this Embodiment can be manufactured according to said process.
　次いで、図４に基づいて、吸収性物品の包装体１００の折り畳み方法を説明する。図４は、吸収性物品の包装体１００の折り畳み工程を模式的に示した図である。吸収性物品の包装体１００の折り畳み工程は、吸収性物品載置工程と、第１折り工程と、第２折り工程と、切断工程と、第３折り工程と、第４折り工程と、テープ貼付工程と、を有する。 Next, a method for folding the absorbent article package 100 will be described with reference to FIG. FIG. 4 is a diagram schematically showing a folding process of the absorbent article packaging body 100. The folding process of the absorbent article package 100 includes an absorbent article placing process, a first folding process, a second folding process, a cutting process, a third folding process, a fourth folding process, and a tape application. And a process.
　吸収性物品載置工程Ｓ１０１では、包装シート７０上に、吸収性物品１、本体シート６１及びフラップシート６２が配置される。なお、１個の吸収性物品１を個別に包装する寸法の包装シート７０上に吸収性物品１を配置してもよいし、例えば、搬送方向に沿って連続する包装シート上に、所定間隔を空けて複数の吸収性物品を配置するように構成してもよい。 In the absorbent article placement step S101, the absorbent article 1, the main body sheet 61, and the flap sheet 62 are disposed on the packaging sheet 70. In addition, you may arrange | position the absorbent article 1 on the packaging sheet 70 of the dimension which wraps one absorbent article 1 separately, for example, a predetermined space | interval is provided on the packaging sheet continuous along a conveyance direction. You may comprise so that several absorbent articles may be arrange | positioned emptying.
　第１折り工程Ｓ１０２では、包装シート７０と吸収性物品１とが、幅方向における吸収性物品１の一方の端部側を含む端部領域側から、長手方向Ｌに沿った第１長手折り目ＦＬ１（図１参照）を基点に内側に折り返される。 In 1st folding process S102, the packaging sheet 70 and the absorbent article 1 are the 1st longitudinal fold FL1 along the longitudinal direction L from the edge part area | region side including the one edge part side of the absorbent article 1 in the width direction. It is folded inward from the base point (see FIG. 1).
　第２折り工程Ｓ１０３では、包装シート７０と吸収性物品１とが、幅方向Ｗにおける吸収性物品１の他方の端部側を含む端部領域側から、長手方向Ｌに沿った第２長手折り目ＦＬ２（図１参照）を基点に内側に折り返される。 In the second folding step S103, the packaging sheet 70 and the absorbent article 1 are second longitudinal folds along the longitudinal direction L from the end region side including the other end side of the absorbent article 1 in the width direction W. Folded inward from FL2 (see FIG. 1).
　次いで、切断工程Ｓ１０４では、第２長手折り目ＦＬ２を基点に折り返された吸収性物品１及び包装シート７０の連続体が、幅方向に沿った切断線に沿って切断される。包装シート７０及び吸収性物品１は、切断されることによって、個々の製品長となる。 Next, in the cutting step S104, the continuous body of the absorbent article 1 and the packaging sheet 70 folded back with the second longitudinal fold FL2 as a base point is cut along a cutting line along the width direction. The packaging sheet 70 and the absorbent article 1 are cut into individual product lengths.
　第３折り工程Ｓ１０５では、包装シート７０と吸収性物品１とが、幅方向Ｗに沿った第１幅折り目ＦＷ１を基点に折り返される。第３折り工程Ｓ１０５は、搬送される吸収性物品１及び包装シート７０が、折り畳みプレートＰによって上方から押圧されることによって折り畳まれる。 In the third folding step S105, the packaging sheet 70 and the absorbent article 1 are folded back based on the first width fold FW1 along the width direction W. In the third folding step S105, the conveyed absorbent article 1 and the packaging sheet 70 are folded by being pressed from above by the folding plate P.
　第４折り工程Ｓ１０６では、包装シート７０と吸収性物品１とが、幅方向Ｗに沿った第２幅折り目ＦＷ２を基点に折り返される。第４折り工程Ｓ１０６は、搬送される吸収性物品１及び包装シート７０が、折り畳みプレートＰによって側方から押圧されることによって折り畳まれる。 In the fourth folding step S106, the packaging sheet 70 and the absorbent article 1 are folded back with the second width fold line FW2 along the width direction W as a base point. In the fourth folding step S106, the conveyed absorbent article 1 and the packaging sheet 70 are folded by being pressed from the side by the folding plate P.
　テープ貼付工程Ｓ１０７では、粘着テープ７５によって包装シートの長手方向の前端部が、包装シートの表面に貼付される。粘着テープ７５は、一端が包装シートの長手方向の前端部に接合され、他端が第２幅折り目ＦＷ２を基点として折り返された状態で包装シートの表面に剥離可能に貼付される。 In the tape affixing step S107, the front end portion of the packaging sheet in the longitudinal direction is affixed to the surface of the packaging sheet by the adhesive tape 75. The adhesive tape 75 is detachably attached to the surface of the packaging sheet with one end joined to the front end in the longitudinal direction of the packaging sheet and the other end folded back with the second width fold FW2 as a base point.
　このような折り畳み方法によれば、吸収性物品１を包装シート７０によってコンパクトに包装することができる。具体的には、吸収性物品及び包装シートの平面面積を広げた場合と比べて約１／９にすることができるため、吸収性物品をコンパクトにすることができる。吸収性物品１を小型化することにより、小物入れ、ポシェット等のバッグに収納する場合、バッグの収納スペースを大きく占有する事がなく、簡便な携帯を可能とする。また、吸収性物品１をコンパクトに包装することにより、使用時にトイレ等に携帯する際に、折り返さない状態でも手の中に配置し、他人から見えないように保持する事が可能となる。 According to such a folding method, the absorbent article 1 can be compactly packaged by the packaging sheet 70. Specifically, the absorbent article and the packaging sheet can be reduced to about 1/9 compared with the case where the planar area of the absorbent article and the packaging sheet is expanded, so that the absorbent article can be made compact. By reducing the size of the absorbent article 1, when storing it in a bag such as an accessory case or a pochette, it does not occupy a large space for storing the bag, and can be easily carried. Further, by packing the absorbent article 1 in a compact manner, it can be placed in the hand even when it is not folded when being carried in a toilet or the like during use, and can be kept from being seen by others.
　次いで、図１、図５及び図６に基づいて、圧搾部及び着色部について詳細に説明する。図５は、図３に示す断面図のＢ部分及びＣ部分の拡大図である。図６は、図１に示す平面図のＤ部分の拡大図である。 Next, the squeezing part and the coloring part will be described in detail based on FIG. 1, FIG. 5 and FIG.

The 1st pressing part 23 is dot-shaped, and multiple are arrange | positioned at intervals. In FIG. 6, the space | interval D1 of a 1st pressing part is shown.
　第２圧搾部２４は、吸収体３０を構成する吸収シート３１及び下側吸収コア３２Ａと、セカンドシート１１と、表面シート１０と、が厚み方向に圧縮されている。第２圧搾部２４は、点状であり、間隔を空けて複数配置されている。第２圧搾部の間隔Ｄ２は、第１圧搾部の間隔Ｄ１よりも長い。第２圧搾部２４は、第１領域Ｒ１よりも長手方向外側と、第２領域Ｒ２よりも幅方向外側と、に形成されている。 In the second pressing part 24, the absorbent sheet 31 and the lower absorbent core 32A, the second sheet 11, and the top sheet 10 constituting the absorbent body 30 are compressed in the thickness direction. The 2nd pressing part 24 is dot-shaped, and multiple are arrange | positioned at intervals. The space | interval D2 of a 2nd pressing part is longer than the space | interval D1 of a 1st pressing part. The 2nd pressing part 24 is formed in the longitudinal direction outer side from 1st area | region R1, and the width direction outer side from 2nd area | region R2.
　第３圧搾部２５は、セカンドシート１１と、表面シート１０と、が厚み方向に圧縮されている。第３圧搾部２５は、点状であり、間隔を空けて複数配置されている。第３圧搾部２５の間隔Ｄ３は、第１圧搾部の間隔Ｄ１よりも長く、第２圧搾部の間隔とほぼ同じである。 In the third pressing part 25, the second sheet 11 and the top sheet 10 are compressed in the thickness direction. The 3rd pressing part 25 is dot-shaped, and multiple are arrange | positioned at intervals. The interval D3 of the third pressing unit 25 is longer than the interval D1 of the first pressing unit and is substantially the same as the interval of the second pressing unit.
　更に、圧搾部は、第２領域Ｒ２において第１圧搾部２３よりも前方に配置された第４圧搾部２６と、第２領域Ｒ２において第１圧搾部２３よりも後方に配置された第５圧搾部２７と、を有する。第４圧搾部２６及び第５圧搾部２７は、第１圧搾部２３と略同じ間隔を空けて複数配置されている。第４圧搾部２６は、前方に向かって凸形状となるように配置されており、第５圧搾部は、後方に向かって凸形状になるように配置されている。 Furthermore, a pressing part is the 4th pressing part 26 arrange | positioned ahead of the 1st pressing part 23 in 2nd area | region R2, and the 5th pressing part arrange | positioned back rather than the 1st pressing part 23 in 2nd area | region R2. Part 27. A plurality of fourth pressing parts 26 and fifth pressing parts 27 are arranged at substantially the same interval as the first pressing part 23. The 4th pressing part 26 is arrange | positioned so that it may become convex shape toward the front, and the 5th pressing part is arrange | positioned so that it may become convex shape toward back.
　なお、吸収性物品の圧搾部は、少なくとも表面シート１０及びセカンドシートを厚み方向Ｔに圧縮して形成されていればよく、種々の構成を採用することができる。例えば、プレス加工やエンボス加工によって形成することができ、その形状は、格子網やハニカム形状であってもよい。また、本実施の形態の圧搾部は、それぞれ非連続的に配置された複数の点状の圧搾部によって構成されているが、連続して線状に形成されていてもよい。 In addition, the pressing part of an absorbent article should just be formed by compressing at least the surface sheet 10 and the second sheet in the thickness direction T, and various configurations can be adopted. For example, it can be formed by pressing or embossing, and the shape thereof may be a lattice network or a honeycomb shape. Moreover, although the pressing part of this Embodiment is comprised by the several dotted | punctate pressing part each arrange | positioned discontinuously, it may be formed linearly continuously.
　本実施の形態に係る圧搾部は、図５に示すように、厚み方向において衣服当接面側に位置する底部２３Ａ、２４Ａ、２５Ａと、各底部の周囲から肌当接面側に向けて厚み方向に延びる壁部２３Ｂ、２４Ｂ、２５Ｂと、を備えている。壁部の厚みは、表面シートの厚みよりも長くなるように構成されている。 As shown in FIG. 5, the pressing portion according to the present embodiment has a bottom 23A, 24A, 25A located on the clothing contact surface side in the thickness direction, and a thickness from the periphery of each bottom toward the skin contact surface. Wall portions 23B, 24B, and 25B extending in the direction. The thickness of the wall is configured to be longer than the thickness of the top sheet.
　また、圧搾部が形成されているセカンドシート１１には、着色部１２が設けられており、圧搾部と着色部とは一部重なって設けられている。第１圧搾部２３の間隔Ｄ１、第２圧搾部２４の間隔Ｄ２及び第３圧搾部２５の間隔Ｄ３は、着色部１２の間隔Ｄ１２と異なるように構成されている。着色部１２の間隔は、いずれの圧搾部の間隔Ｄ１、Ｄ２、Ｄ３よりも長い。 Moreover, the colored sheet 12 is provided in the second sheet 11 in which the compressed part is formed, and the compressed part and the colored part are provided so as to partially overlap. The interval D1 of the first pressing unit 23, the interval D2 of the second pressing unit 24, and the interval D3 of the third pressing unit 25 are configured to be different from the interval D12 of the coloring unit 12. The interval between the colored portions 12 is longer than the intervals D1, D2, and D3 between any compressed portions.
　また、吸収性物品１の平面視において、圧搾部の面積は、着色部の面積よりも小さく構成され、複数の圧搾部のうち一部の圧搾部は、着色部に重なって配置されており、他の圧搾部は、着色部とずれて配置されている。***口当接領域の中心を含む第１領域Ｒ１の外周に沿って第１圧搾部２３が配置されている。よって、第１圧搾部２３によって***口当接領域に排出された体液を引き込むことができる。更に、第１領域Ｒ１の長手方向外側に位置する第２領域Ｒ２には、第２圧搾部２４が形成されているため、第１領域Ｒ１よりも長手方向外側に拡散した体液を、第２圧搾部２４によって引き込むことができる。 Moreover, in the planar view of the absorbent article 1, the area of the pressing part is configured to be smaller than the area of the coloring part, and some of the pressing parts are arranged so as to overlap the coloring part, The other pressing part is arrange | positioned and shifted | deviated from the coloring part. The 1st pressing part 23 is arrange | positioned along the outer periphery of 1st area | region R1 containing the center of an excretion opening | mouth contact | abutting area | region. Therefore, the bodily fluid discharged | emitted by the 1st pressing part 23 to the excretion opening | mouth contact | abutting area | region can be drawn in. Furthermore, since the 2nd pressing part 24 is formed in 2nd area | region R2 located in the longitudinal direction outer side of 1st area | region R1, the body fluid which spread | diffused to the longitudinal direction outer side rather than 1st area | region R1 is 2nd squeezed. It can be pulled in by the part 24.
　また、第１領域Ｒ１には、表面シート１０とセカンドシート１１とを圧縮した第３圧搾部２５が形成されている。よって、第１領域Ｒ１の吸収体には、圧搾部が形成されてなく、***口に当接する第１領域の嵩を維持し、クッション性を維持できる。更に、表面シートの表面に排出された体液を、第３圧搾部によって吸収体に移行させ易くなり、体液の引き込み性を向上させることができる。 Moreover, the 3rd pressing part 25 which compressed the surface sheet 10 and the second sheet | seat 11 is formed in 1st area | region R1. Therefore, the compression part is not formed in the absorber of 1st area | region R1, the volume of the 1st area | region which contact | abuts an excretion opening | mouth is maintained, and cushioning properties can be maintained. Furthermore, the body fluid discharged to the surface of the topsheet can be easily transferred to the absorbent body by the third pressing unit, and the body fluid drawing-in property can be improved.
　圧搾部を設けることにより、圧搾部及びその周囲の密度が高くなり、毛管力によって体液の引き込み性が高くなる。例えば、第１領域の周囲の第２領域は、３層圧縮されて圧搾部が形成されており、第１領域の圧搾部よりも多くの層数が圧縮されて圧搾部が形成されているため、圧搾部が形成された部分の密度が高くなる。 By providing the squeezing part, the density of the squeezing part and its surroundings is increased, and the pullability of body fluid is increased by capillary force. For example, the second region around the first region is compressed by three layers to form a squeezed portion, and the compressed portion is formed by compressing more layers than the squeezed portion of the first region. The density of the portion where the compressed portion is formed is increased.
　圧搾部が形成される層数が多い程、密度も高くなり、体液の引き込み性も高くなる。このように密度が高くなると、比較的少量の体液の引き込み速度が高まる。その一方、密度が高り過ぎると、多量の体液の保持性が低下し、吸収しきれなかった体液が表面シート上に滞留してしまうことがある。 The greater the number of layers in which the compressed parts are formed, the higher the density and the higher the body fluid drawability. As the density increases in this way, the drawing speed of a relatively small amount of body fluid increases. On the other hand, if the density is too high, the retention of a large amount of bodily fluid may decrease, and bodily fluid that cannot be absorbed may stay on the topsheet.
　しかし、比較的体液が多く排出される第１領域Ｒ１の圧搾部は、吸収体が圧縮されずに表面シート及びセカンドシートのみが圧縮されているため、第１領域の密度が高くなり過ぎることが抑制され、多量の経血を瞬間的に格納することができる。一方、第１領域Ｒ１の外周及びその周囲には、第１圧搾部２３及び第２圧搾部２４が形成されているため、第１領域において格納しきれずに流れてきた経血をその周囲で瞬間的に引き込むことが可能になる。よって、経血量の多い場合における漏れリスクの低減しつつ、経血量が少ない場合におけるドライ感を実現できる。 However, in the compressed portion of the first region R1 where a relatively large amount of body fluid is discharged, only the topsheet and the second sheet are compressed without compressing the absorbent body, and thus the density of the first region may be too high. It is suppressed and a large amount of menstrual blood can be stored instantaneously. On the other hand, since the 1st pressing part 23 and the 2nd pressing part 24 are formed in the outer periphery of 1st area | region R1, and its circumference | surroundings, the menstrual blood which flowed without being able to store in the 1st area | region is instantaneously produced in the circumference | surroundings. Can be pulled in. Accordingly, it is possible to realize a dry feeling when the amount of menstrual blood is small while reducing the risk of leakage when the amount of menstrual blood is large.
　また、圧搾部の壁部は、肌当接面側側から衣服当接面側に向かって厚み方向に延伸しており、表面シート及びセカンドシートの厚みが薄くなる。また、壁部と重なった着色部も延伸している。表面シート及びセカンドシートの厚みが壁部において薄いため、壁部を介して体液が透過し易くなる。よって、圧搾部の壁部から吸収体に向かって液が移行しやすくなり、体液の引き込み性を高めることができる。 Moreover, the wall part of the pressing part is extended in the thickness direction from the skin contact surface side to the clothing contact surface side, and the thickness of the top sheet and the second sheet is reduced. Moreover, the colored part which overlapped with the wall part is also extended | stretched. Since the thickness of the top sheet and the second sheet is thin at the wall portion, the body fluid can easily pass through the wall portion. Therefore, it becomes easy for a liquid to transfer toward the absorber from the wall part of a pressing part, and the drawability of a bodily fluid can be improved.
　また、第１領域Ｒ１と第２領域Ｒ２には、複数の着色部１２が設けられているため、吸収性物品全体に亘って装飾性を高めることができる。着色部は、一般的に疎水性の樹脂（顔料含）が被覆することで形成されている。従って，着色部は、体液を保持し難い。また、表面シート１０とセカンドシート１１とは、圧搾部によって互いに接合されている。しかし、着色部が配置された部分は、表面シートとセカンドシートとの間に着色部が配置されているため、表面シート１０とセカンドシート１１との接合強度が低くなる。よって、着色部が配置された部分の圧搾部は、着色部が配置されていない部分の圧搾部と比較して、圧搾部が崩れやすくなる。しかし、着色部は、第１圧搾部の間隔と第２圧搾部の間隔と異なるように複数配置されており、複数の圧搾部のうち一部の圧搾部は、着色部に重なって配置されており、他の圧搾部は、前記着色部とずれて配置されている。よって、圧搾部と着色部が重複する場所は局所的である。 In addition, since the plurality of colored portions 12 are provided in the first region R1 and the second region R2, it is possible to enhance the decorativeness over the entire absorbent article. The colored portion is generally formed by covering with a hydrophobic resin (including pigment). Therefore, the colored part is difficult to retain body fluid. Further, the top sheet 10 and the second sheet 11 are joined to each other by the pressing part. However, since the colored portion is disposed between the top sheet and the second sheet in the portion where the colored portion is disposed, the bonding strength between the top sheet 10 and the second sheet 11 is low. Therefore, the compressed portion of the portion where the colored portion is disposed is more easily collapsed than the compressed portion of the portion where the colored portion is not disposed. However, a plurality of colored portions are arranged to be different from the interval between the first compressed portions and the interval between the second compressed portions, and some of the compressed portions are arranged so as to overlap the colored portions. And the other pressing part is shifted | deviated from the said coloring part. Therefore, the place where a pressing part and a coloring part overlap is local.
　一部分（例えば、***口当接領域）に偏って着色部が配置される構成と比較して、局所的な体液の引き込み性の低下及び局所的な圧搾部の強度の低下を抑制できる。したがって，漏れリスクを回避しつつ、デザイン性を高めることが可能になる。また、圧搾部と着色部とが部分的に重なって配置されていることにより、圧縮部に沿って経血を拡散する一方、圧搾部と印刷部とが重なった領域で拡散を抑制できる。よって、体液の前後方向への過度な拡散を抑制でき、前後の漏れを防止できる。 Compared with a configuration in which the colored portion is biased toward a part (for example, the excretory opening contact region), it is possible to suppress a decrease in local body fluid drawability and a decrease in strength of the local compressed portion. Therefore, it is possible to improve the design while avoiding the risk of leakage. Moreover, while the pressing part and the colored part are arranged so as to overlap each other, menstrual blood is diffused along the compression part, while diffusion can be suppressed in a region where the pressing part and the printing part overlap. Therefore, excessive diffusion of body fluid in the front-rear direction can be suppressed, and front-rear leakage can be prevented.
　また、着色部は、圧搾部と重なった部分において厚み方向に延伸され、圧搾部の壁部において部分的に分断される。この着色部の分断部分を介して体液が吸収体に移行し易くなる。 Also, the colored portion is stretched in the thickness direction at the portion overlapping the compressed portion, and is partially divided at the wall portion of the compressed portion. It becomes easy for a bodily fluid to transfer to an absorber through the divided part of this coloring part.
　また、平面視において各圧搾部の面積は、各着色部１２の面積より小さい。着色部は、圧搾部と重なった部分において厚み方向に延伸され、圧搾部の壁部において部分的に分断される。この着色部の分断部分を介して体液が吸収体に移行し易くなる。 Moreover, the area of each pressing part is smaller than the area of each coloring part 12 in plan view. The colored portion is stretched in the thickness direction at the portion overlapping the compressed portion, and is partially divided at the wall portion of the compressed portion. It becomes easy for a bodily fluid to transfer to an absorber through the divided part of this coloring part.
　更に、着色部には、底部が設けられているため、着色部と圧搾部とが重なって配置された場合であっても、着色部を視認し易くすることができる。圧搾部の壁部においては、厚み方向に延伸されて着色部の視認性が低下するが，底面の着色部の視認性は保持される。よって、平面視におけるデザインのアピアランスを保持できる。 Furthermore, since the colored portion is provided with a bottom portion, the colored portion can be easily visually recognized even when the colored portion and the compressed portion are arranged to overlap each other. In the wall part of a pressing part, it is extended | stretched in the thickness direction and the visibility of a colored part falls, but the visibility of the colored part of a bottom face is maintained. Therefore, the appearance of the design in plan view can be maintained.
　また、圧搾部の間隔を適宜調整することにより、デザインの濃淡を表現することができる。例えば、圧搾部の間隔が狭いほど、表面シート及びセカンドシートの密度が高くなり、表面シートと着色部の厚み方向の距離が近づくため、着色部が濃く見え易くなる。また、圧搾部の面積を適宜調整することにより、デザインの濃淡を表現することができる。圧搾部の面積が大きいほど、表面シートと密着する面積が増えるため、表面シート側の密度が高くなる。 Also, the shade of the design can be expressed by appropriately adjusting the interval between the compressed parts. For example, the narrower the interval between the compressed parts, the higher the density of the top sheet and the second sheet, and the closer the distance in the thickness direction between the top sheet and the colored part, the darker the colored part tends to appear. Moreover, the shade of a design can be expressed by adjusting the area of a pressing part suitably. As the area of the pressing portion is larger, the area that is in close contact with the topsheet increases, and thus the density on the topsheet side increases.
　更に、図６に示すように、着色部は、平面視における着色部の長さが圧搾部の間隔よりも長い第１着色部１３を備える。このような比較的面積の大きい第１着色部１３は、少なくとも１以上の圧搾部と重なって配置される。よって、着色部１２が配置された領域における液流れを抑制し、液流れによる漏れを低減できる。なお、平面視における長さが圧搾部の間隔よりも長い第１着色部１３とは、長手方向における長さが圧搾部の長手方向の間隔よりも長い着色部と、幅方向における長さが圧搾部の幅方向の間隔よりも長い着色部と、を含む概念である。 Furthermore, as shown in FIG. 6, the colored portion includes a first colored portion 13 in which the length of the colored portion in plan view is longer than the interval between the compressed portions. The first colored portion 13 having a relatively large area is arranged so as to overlap at least one compressed portion. Therefore, the liquid flow in the area | region where the coloring part 12 is arrange | positioned can be suppressed, and the leak by a liquid flow can be reduced. In addition, the 1st coloring part 13 whose length in planar view is longer than the space | interval of a pressing part is the coloring part whose length in a longitudinal direction is longer than the space | interval of the longitudinal direction of a pressing part, and the length in the width direction is pressing. And a colored portion longer than the interval in the width direction of the portion.
　また、着色部は、平面視における着色部の長さが圧搾部の間隔よりも短い第２着色部１４を備える。このような第２は、隣接する圧搾部間に配置可能となり、着色部による圧搾部の強度の低下を抑制できる。なお、平面視における長さが圧搾部の間隔よりも短い第２着色部１４とは、長手方向における長さが圧搾部の長手方向の間隔よりも短い着色部と、幅方向における長さが圧搾部の幅方向の間隔よりも短い着色部と、を含む概念である。 Further, the colored portion includes a second colored portion 14 in which the length of the colored portion in plan view is shorter than the interval between the compressed portions. Such 2nd can be arrange | positioned between adjacent pressing parts, and can suppress the fall of the intensity | strength of the pressing part by a coloring part. In addition, the 2nd coloring part 14 whose length in planar view is shorter than the space | interval of a pressing part is the coloring part whose length in a longitudinal direction is shorter than the space | interval of the longitudinal direction of a pressing part, and the length in the width direction is pressing. And a colored portion shorter than the interval in the width direction of the portion.
　次いで、図７に基づいて、変形例に係る吸収性物品２について説明する。図７は、変形例に係る吸収性物品２を示す図であり、図７（ａ）は、平面図である。図７（ｂ）は、変形例に係る吸収性物品２を構成する表面シートの平面図である。図７（ｃ）は、変形例に係る吸収性物品２を構成するセカンドシートの平面図である。 Next, the absorbent article 2 according to the modification will be described with reference to FIG. FIG. 7 is a view showing an absorbent article 2 according to a modification, and FIG. 7 (a) is a plan view. FIG.7 (b) is a top view of the surface sheet which comprises the absorbent article 2 which concerns on a modification. FIG.7 (c) is a top view of the second sheet which comprises the absorbent article 2 which concerns on a modification.
　変形例に係る吸収性物品の着色部は、表面シート１０のセカンドシート側の面に設けられた表面着色部１２Ａと、セカンドシート１１の吸収体側の面に設けられたセカンド着色部１２Ｂと、を有する。表面着色部１２Ａとセカンド着色部１２Ｂは、長手方向と幅方向のうち、少なくともいずれか一方にずれて配置されている。 The colored portion of the absorbent article according to the modification includes a surface colored portion 12A provided on the second sheet side surface of the surface sheet 10 and a second colored portion 12B provided on the absorber side surface of the second sheet 11. Have. The surface coloring portion 12A and the second coloring portion 12B are arranged so as to be shifted to at least one of the longitudinal direction and the width direction.
　表面着色部１２Ａとセカンド着色部１２Ｂは、いずれも吸収性物品２の表面シート側から視認可能に構成されている。表面着色部１２Ａは、葉と茎であり、セカンド着色部１２Ｂは、花である。このように表面着色部１２Ａとセカンド着色部１２Ｂは、絵柄、色及び形状のうち少なくともいずれかが異なるように構成されている。このような表面着色部１２Ａとセカンド着色部１２Ｂとの組み合わせによって、デザイン性を高めることができる。 The surface coloring portion 12A and the second coloring portion 12B are both configured to be visible from the surface sheet side of the absorbent article 2. The surface coloring portion 12A is leaves and stems, and the second coloring portion 12B is flowers. As described above, the surface coloring portion 12A and the second coloring portion 12B are configured such that at least one of the pattern, color, and shape is different. The combination of the surface coloring portion 12A and the second coloring portion 12B can enhance the design.
　表面着色部１２Ａとセカンド着色部１２Ｂは、厚み方向にずれて配置される。よって、デザインが２次元から３次元に広がり、視覚上の楽しさをより高めることが可能になる。更に、吸収性物品２に立体感を付与することにより、着用者は、実際の吸収性物品２の厚み以上に視覚上の厚みを感じることでき、漏れへの安心感を得ることができる。 The surface coloring portion 12A and the second coloring portion 12B are arranged so as to be shifted in the thickness direction. Therefore, the design can be expanded from 2D to 3D, and visual enjoyment can be further enhanced. Furthermore, by providing the absorbent article 2 with a three-dimensional effect, the wearer can feel a visual thickness that is greater than the actual thickness of the absorbent article 2 and can feel a sense of security against leakage.
　また、変形例に係る着色部１２は、長手方向に沿っており、吸収性物品の幅方向中央よりも両側部に配置されている。このように着色部を配置することにより、吸収性物品の幅方向中央に着色部が配置されず、吸収性物品の幅方向中央においてスムーズに体液を透過させることができる。また、吸収性物品の幅方向中央で吸収された経血は、拡散する。しかし、長手方向に沿った圧搾部によって、吸収性物品の幅方向中央から幅方向外側への拡散を抑制できる。よって、横漏れを防止できる。 Moreover, the coloring part 12 which concerns on a modification is along the longitudinal direction, and is arrange | positioned in the both sides rather than the center of the width direction of an absorbent article. By arranging the colored part in this way, the colored part is not arranged at the center in the width direction of the absorbent article, and the body fluid can be smoothly transmitted at the center in the width direction of the absorbent article. Moreover, menstrual blood absorbed at the center in the width direction of the absorbent article diffuses. However, diffusion from the center in the width direction of the absorbent article to the outer side in the width direction can be suppressed by the compressed portion along the longitudinal direction. Therefore, side leakage can be prevented.

　例えば、圧搾部は、少なくとも第１圧搾部及び第２圧搾部を備えていればよく、第３圧搾部、第４圧搾部及び第５圧搾部を備えていなくてもよい。また、第２圧搾部は、少なくとも第１領域よりも長手方向外側に設けられていればよく、第１領域よりも幅方向外側に設けられていなくてもよい。 For example, the pressing part should just be equipped with the 1st pressing part and the 2nd pressing part at least, and does not need to be provided with the 3rd pressing part, the 4th pressing part, and the 5th pressing part.
