　後部サイドフラップ４０Ｂには、前胴回り領域Ｓ１の外装シート２０に係止する止着部材４１が設けられる。止着部材４１は、表面シート１０に接合されている。止着部材４１は、表面シート１０よりも幅方向外側に延出している。止着部材４１は、後述するターゲット部５０に係合するフック部４１Ａと、フック部４１Ａが取り付けられる固定片４１Ｂとによって構成される。フック部４１Ａには、ターゲット部５０を構成する不織布層に引っ掛かるフック（図示せず）が複数形成されている。止着部材４１とターゲット部５０は、フックとループの係止システムを構成し、フックでループを引っ掛けて試着するものであり、止着部材４１はフックとして機能し、ターゲット部５０はループとして機能する。 The rear side flap 40B is provided with a fastening member 41 that is engaged with the exterior sheet 20 in the front waistline region S1. The fastening member 41 is joined to the top sheet 10. The fastening member 41 extends outward in the width direction from the top sheet 10. The fastening member 41 includes a hook portion 41A that engages with a target portion 50, which will be described later, and a fixed piece 41B to which the hook portion 41A is attached. A plurality of hooks (not shown) that are hooked on the nonwoven fabric layer constituting the target portion 50 are formed on the hook portion 41A. The fastening member 41 and the target unit 50 constitute a hook and loop locking system, and the loop is hooked with the hook to try on. The fastening member 41 functions as a hook, and the target unit 50 functions as a loop. To do.
　ターゲット部５０は、前胴回り領域の外方向の外面となるバック不織布２１の外方向の外面に配置されている。図３は、図２のＡ部分の拡大断面図である。図４は、ターゲット部を示しており、図４（ａ）は、平面図であり、図４（ｂ）は、Ｂ部分の模式拡大図である。 The target unit 50 is disposed on the outer surface of the outer side of the back nonwoven fabric 21 that is the outer surface of the front waistline region. FIG. 3 is an enlarged cross-sectional view of a portion A in FIG. FIG. 4 shows the target part, FIG. 4 (a) is a plan view, and FIG. 4 (b) is a schematic enlarged view of the B part.
　ターゲット部５０は、第１不織布層５１と、第２不織布層５２と、が積層されて構成されている。ターゲット部５０は、止着部材４１のフック部４１Ａに設けられたフックが引っ掛かるように構成されており、ループとして機能する。第２不織布層５２は、第１不織布層５１よりも外方向に配置されている。ターゲット部は、第１不織布層５１と第２不織布層５２とが積層された状態で厚み方向に圧搾された圧搾部Ｃが形成されている。第１不織布層５１には、印刷が施された印刷部５４が設けられている。 The target unit 50 is configured by laminating a first nonwoven fabric layer 51 and a second nonwoven fabric layer 52. The target portion 50 is configured so that a hook provided on the hook portion 41A of the fastening member 41 is hooked, and functions as a loop. The second nonwoven fabric layer 52 is disposed outward from the first nonwoven fabric layer 51. The target portion is formed with a compressed portion C that is compressed in the thickness direction in a state where the first nonwoven fabric layer 51 and the second nonwoven fabric layer 52 are laminated. The first nonwoven fabric layer 51 is provided with a printing unit 54 on which printing has been performed.
　第１不織布層５１は、スパンボンド不織布層５１Ａと、メルトブローン不織布層５１Ｂと、スパンボンド不織布層５１Ａと、が積層されたＳＭＳ不織布によって構成されている。第２不織布層５２は、スルーエアー不織布層によって構成されている。 The first nonwoven fabric layer 51 is composed of an SMS nonwoven fabric in which a spunbond nonwoven fabric layer 51A, a meltblown nonwoven fabric layer 51B, and a spunbond nonwoven fabric layer 51A are laminated. The 2nd nonwoven fabric layer 52 is comprised by the through-air nonwoven fabric layer.
　スパンボンド不織布層５１Ａは、紡糸ノズルから出た樹脂を冷却し、その繊維を直接捕集して不織布を形成するため、長繊維であり、その繊維径が比較的太い。一般的に、スパンボンド不織布層５１Ａの繊維は、メルトブローン不織布層５１Ｂを構成する繊維と比較して、繊維径が太く、その繊維長が長い。 The spunbond nonwoven fabric layer 51A is a long fiber and has a relatively large fiber diameter because it cools the resin from the spinning nozzle and directly collects the fibers to form a nonwoven fabric. Generally, the fibers of the spunbond nonwoven fabric layer 51A have a larger fiber diameter and a longer fiber length than the fibers constituting the meltblown nonwoven fabric layer 51B.
　メルトブローン不織布層５１Ｂは、紡糸ノズルから出た樹脂をホットエアーで延伸し、その繊維を捕集するため、長繊維であり、その繊維径が細い。一般的に、メルトブローン不織布層５１Ｂを構成する繊維は、スパンボンド不織布層５１Ａを構成する繊維と比較して、繊維径が細く、その繊維長が短い。 The melt blown nonwoven fabric layer 51B is a long fiber and has a thin fiber diameter in order to draw resin from the spinning nozzle with hot air and collect the fiber. Generally, the fibers constituting the meltblown nonwoven fabric layer 51B have a smaller fiber diameter and a shorter fiber length than the fibers constituting the spunbond nonwoven fabric layer 51A.
　スルーエアー不織布層は、紡糸ノズルから出た樹脂を予め切断した短繊維を積層した後、熱風を与え、繊維を低密度の状態で互いに融着させた不織布である。スルーエアー不織布層は、低密度であるため、嵩高性とクッション性を有している。 The through-air nonwoven fabric layer is a nonwoven fabric obtained by laminating short fibers obtained by cutting a resin from a spinning nozzle in advance and then applying hot air to fuse the fibers together in a low density state. Since the through-air nonwoven fabric layer has a low density, it has bulkiness and cushioning properties.
　吸収性物品の外方向外側に配置される第２不織布層は、スルーエアー不織布層であり、メルトブローン不織布層と比較して嵩高である。よって、止着部材４１を止着させることができる。また、印刷が施された第１不織布層５１には止着部材４１が直接止着しないため、止着部材４１を繰り返し着脱した場合であっても、印刷部５４が摩耗することを抑制し、印刷部５４の表示状態を維持できる。 The second nonwoven fabric layer disposed on the outer side of the absorbent article is a through-air nonwoven fabric layer, which is bulky compared to the meltblown nonwoven fabric layer. Therefore, the fastening member 41 can be fastened. In addition, since the fastening member 41 does not directly attach to the printed first nonwoven fabric layer 51, even when the fastening member 41 is repeatedly attached and detached, the print portion 54 is prevented from being worn, The display state of the printing unit 54 can be maintained.
　また、２層のスパンボンド不織布層とメルトブローン不織布層とを積層して第１不織布層を構成することにより、耐久性を高めることができる。また、スパンボンド不織布層は、光を透過しやすく、光が拡散し難くなり、スパンボンド不織布層を介しても、印刷部を認識させ易くすることができる。 Moreover, durability can be improved by laminating | stacking two layers of spunbond nonwoven fabric layers and a melt blown nonwoven fabric layer, and comprising a 1st nonwoven fabric layer. In addition, the spunbonded nonwoven fabric layer can easily transmit light and light hardly diffuses, and the printed portion can be easily recognized even through the spunbonded nonwoven fabric layer.
　印刷部５４は、第１不織布層５１に形成されており、具体的には、内方向側のスパンボンド不織布層側から印刷が施されている。印刷部５４は、第１色で印刷された第１印刷部５４Ａと、第１色よりも濃い第２色によって印刷された第２印刷部５４Ｂと、を有している。なお、印刷部の色は、１色以上であればよく、３色以上でもよい。 The printing unit 54 is formed on the first nonwoven fabric layer 51, and specifically, printing is performed from the spunbond nonwoven fabric layer side on the inner side. The printing unit 54 includes a first printing unit 54A printed with a first color and a second printing unit 54B printed with a second color darker than the first color. In addition, the color of a printing part should just be 1 color or more, and may be 3 colors or more.
　印刷部５４の着色成分は、内方向のスパンボンド不織布層を介してメルトブローン不織布層を構成する細かい繊維間に侵入し、メルトブローン不織布層５１Ｂの内部まで浸透し易い。よって、印刷部の着色状態を維持し易くなる。また、メルトブローン不織布層５１Ｂは、スパンボンド不織布層５１Ａよりも密度が高いため、着色成分を細かく配置でき、細かい柄を表現することが可能となる。 The coloring component of the printing part 54 penetrates between fine fibers constituting the meltblown nonwoven fabric layer through the inwardly oriented spunbond nonwoven fabric layer and easily penetrates into the meltblown nonwoven fabric layer 51B. Therefore, it becomes easy to maintain the colored state of the printing part. Moreover, since the melt blown nonwoven fabric layer 51B has a higher density than the spunbond nonwoven fabric layer 51A, it is possible to arrange the colored components finely and to express a fine pattern.
　また、印刷部は、内方向のスパンボンド不織布層５１Ａ側から印刷を施した場合、比較的密度の高いメルトブローン不織布層５１Ｂで着色成分が留まる。よって、印刷を施す側と反対の面（外面）まで着色成分が通過することを抑制し、印刷時の色抜けを防止できる。例えば、吸収性物品１は、鞄等に入れて運搬することが多く、印刷部５４が第２不織布層５２側に配置されていると、印刷部５４の着色成分が剥離して鞄内の別の収容物に付着するおそれがある。しかし、ターゲット部の内方向の面側に印刷部５４を設けることにより、色移りを抑制できる。 In addition, when the printing unit performs printing from the side of the spunbond nonwoven fabric layer 51A in the inward direction, the coloring component remains in the melt-blown nonwoven fabric layer 51B having a relatively high density. Therefore, it can suppress that a coloring component passes to the surface (outer surface) opposite to the side which performs printing, and can prevent the color omission at the time of printing. For example, the absorbent article 1 is often carried in a bag or the like, and when the printing unit 54 is disposed on the second nonwoven fabric layer 52 side, the coloring component of the printing unit 54 is peeled off and separated in the bag. There is a risk of adhering to the contents. However, by providing the printing unit 54 on the inward surface side of the target unit, color migration can be suppressed.
　ターゲット部５０には、厚み方向に圧搾された圧搾部Ｃが形成された圧搾領域５３Ａと、圧搾部Ｃが形成されていない非圧搾領域５３Ｂとが設けられている。圧搾部Ｃは、平面視にて、凸状の湾曲形状と、凹状の湾曲形状と、が幅方向に隣接し、かつ前後方向に隣接して配置されている。圧搾部は、第１不織布層と第２不織布層とが積層された状態で、第２不織布側から第１不織布側に向かって圧縮されることによって形成されている。 The target part 50 is provided with a pressing area 53A in which a pressing part C compressed in the thickness direction is formed and a non-squeezing area 53B in which the pressing part C is not formed. In the compressed portion C, the convex curved shape and the concave curved shape are arranged adjacent to each other in the width direction and adjacent to each other in the front-rear direction in plan view. The pressing part is formed by being compressed from the second nonwoven fabric side toward the first nonwoven fabric side in a state where the first nonwoven fabric layer and the second nonwoven fabric layer are laminated.
　圧搾部は、ターゲット部の少なくとも一部の領域に設けられていればよく、ターゲット部の全体に設けられていてもよいし、一部の領域であってもよい。例えば、ターゲット部の全体面積に対する圧搾領域の面積比率は、２５％～６０％とすることができる。 The pressing part only needs to be provided in at least a part of the target part, and may be provided in the entire target part, or may be a part of the part. For example, the area ratio of the compressed region to the entire area of the target portion can be 25% to 60%.
　圧搾領域５３Ａは、非圧搾領域５３Ｂに比べて厚み方向の寸法が小さく、光が透過し易い。よって、ターゲット部５０の印刷部５４のうち、圧搾領域５３Ａに設けられた印刷部５４の視認性を、非圧搾領域５３Ｂの印刷部５４の視認性よりも高くすることができる。具体的には、圧搾領域５３Ａの印刷部５４がくっきりと表示され、非圧搾領域５３Ｂの印刷部５４が圧搾領域５３Ａに比べてぼんやりと表示される。よって、平面状に配置された印刷部５４によって立体的な表示を実現することができる。 The compressed region 53A has a smaller dimension in the thickness direction than the non-compressed region 53B, and light is easily transmitted. Therefore, the visibility of the printing part 54 provided in the pressing area 53A in the printing part 54 of the target part 50 can be made higher than the visibility of the printing part 54 in the non-squeezing area 53B. Specifically, the printing part 54 of the compressed area 53A is clearly displayed, and the printed part 54 of the non-pressed area 53B is displayed more dimly than the compressed area 53A. Therefore, a three-dimensional display can be realized by the printing unit 54 arranged in a plane.
　図４に示すように、ターゲット部５０には、圧搾領域５３Ａと非圧搾領域５３Ｂとが設けられ、圧搾領域５３Ａの方が濃く表示される。また、印刷部５４は、第１印刷部５４Ａと第２印刷部５４Ｂとが設けられ、第２印刷部５４Ｂの方が濃く表示される。この印刷部５４の色と圧搾部Ｃの有無との組み合わせにより、４つのパターンで表示することができる。４つのパターンは、圧搾領域５３Ａに配置された第１印刷部５４Ａの表示態様と、非圧搾領域５３Ｂに配置された第１印刷部５４Ａの表示態様と、圧搾領域５３Ａに配置された第２印刷部５４Ｂの表示態様と、非圧搾領域５３Ｂに配置された第２印刷部５４Ｂの表示態様とである。 As shown in FIG. 4, the target part 50 is provided with a compressed area 53A and a non-compressed area 53B, and the compressed area 53A is displayed darker. The printing unit 54 includes a first printing unit 54A and a second printing unit 54B, and the second printing unit 54B is displayed darker. Depending on the combination of the color of the printing part 54 and the presence or absence of the pressing part C, it can be displayed in four patterns. The four patterns include a display mode of the first printing unit 54A arranged in the compressed area 53A, a display mode of the first printing unit 54A arranged in the non-pressed area 53B, and a second print arranged in the compressed area 53A. It is the display mode of the part 54B, and the display mode of the 2nd printing part 54B arrange | positioned in the non-pressing area | region 53B.
　印刷部５４のうち比較的濃い第２印刷部５４Ｂは、圧搾領域５３Ａと非圧搾領域５３Ｂに跨って配置されている。濃い色によって着色された第２印刷部５４Ｂを圧搾領域５３Ａと非圧搾領域５３Ｂとに跨って配置することにより、圧搾部の有無によって厚みが異なる領域に跨って第２印刷部５４Ｂを表示でき、立体的な装飾を施すことができる。 2nd printing part 54B which is comparatively dark among printing parts 54 is arranged ranging over pressing field 53A and non-pressing field 53B. By disposing the second printing part 54B colored with a dark color across the compressed area 53A and the non-squeezed area 53B, the second printed part 54B can be displayed across areas with different thicknesses depending on the presence or absence of the compressed part, Three-dimensional decoration can be given.
　例えば、圧搾領域５３Ａ及びその周囲に第２印刷部を設けると、印刷部によるデザインは明確に見えるが、圧搾領域と非圧搾領域の濃淡が明確になり過ぎ、印刷部によるデザインに加えて、圧搾領域の外形によるデザインが浮かび上がってしまう。また、ターゲット部の全体の色が濃くなるため、ターゲット部の立体感（嵩）がでないように見えてしまう。 For example, when the second printing part is provided in the compressed area 53A and the periphery thereof, the design by the printing part can be clearly seen, but the density of the compressed area and the non-pressed area becomes too clear, and in addition to the design by the printing part, The design due to the outer shape of the area emerges. Moreover, since the color of the whole target part becomes dark, it will seem that the three-dimensional effect (bulk) of a target part is not.
　一方、圧搾領域及びその周囲に第１印刷部を設けると、印刷部によるデザインがぼやけてしまうことがあり、止着部材を止める位置を示す目印の機能を低下させてしまう。また、ターゲット部の全体の色が薄くなるため、ターゲット部の立体感（嵩）がでるように見える。 On the other hand, when the first printing part is provided in the compressed area and the periphery thereof, the design by the printing part may be blurred, and the function of the mark indicating the position where the fastening member is stopped is deteriorated. Moreover, since the color of the whole target part becomes light, it seems that the three-dimensional effect (bulk) of a target part comes out.
　しかし、本実施の形態に係るターゲット部のように、第２印刷部を部分的に圧搾領域に跨って配置することにより、デザイン性と立体感を両立することができる。さらに圧搾部を通して奥側に濃い色が表示されるので奥行きを出すことができる。 However, both the design and the three-dimensional effect can be achieved by disposing the second printing part partially across the compressed area as in the target part according to the present embodiment. Furthermore, since a deep color is displayed on the back side through the pressing unit, the depth can be increased.
　なお、本実施の形態では、第１印刷部及び第２印刷部を、圧搾領域及び非圧搾領域に跨るように配置しているが、少なくとも第２印刷部を圧搾領域及び非圧搾領域に跨るように配置すればよく、第１印刷部を圧搾領域のみに配置してもよいし、第１印刷部を非圧搾領域のみに配置してもよい。 In the present embodiment, the first printing unit and the second printing unit are arranged so as to straddle the pressing region and the non-squeezing region, but at least the second printing unit is straddled across the pressing region and the non-squeezing region. What is necessary is just to arrange | position, and a 1st printing part may be arrange | positioned only to a pressing area | region, and a 1st printing part may be arrange | positioned only to a non-squeezing area | region.
　また、本実施の形態に係る第１印刷部の第１色と第２印刷部の第２色は、例えば、色差が１２～１００の範囲となる関係が好ましい。このような色差となる関係であれば、第１色と第２色とによって濃淡を表示することができる。 Further, it is preferable that the first color of the first printing unit and the second color of the second printing unit according to the present embodiment have a relationship in which the color difference is in the range of 12 to 100, for example. With such a color difference relationship, light and shade can be displayed by the first color and the second color.
　なお、色差は、例えば、以下の方法によって測定することができる。 The color difference can be measured by the following method, for example.
　・測定機器
　機種：ＣＲ－３００
　ヘッド仕様：板径４０ｍｍ、穴径８ｍｍ
　表色系：ＣＩＥ　１９７６（Ｌ＊ａ＊ｂ）
　・測定方法
　測定機器を用いて、白板（Ｌ:４８．０５, ａ:＋２．５０, ｂ:＋１９．６８）の上に印刷されたシートを配置し、印刷された面を測定面として測定し、校正白色値（Ｙ：９２、ｘ：３１．４５、ｙ：３１．９８）に対する色差を算出する。 ・ Measurement equipment Model: CR-300
Head specifications: Plate diameter 40mm, hole diameter 8mm
Color system: CIE 1976 (L * a * b)
・ Measurement method Using a measuring instrument, place a printed sheet on a white plate (L: 48.05, a: +2.50, b: + 19.68) and measure the printed surface as the measurement surface. The color difference with respect to the calibration white value (Y: 92, x: 31.45, y: 31.98) is calculated.
　第２印刷部５４Ｂは、止着部材の位置を合わせるための位置決め部として機能している。この位置決め部として機能する第２印刷部は、前後方向に延び、圧搾領域５３Ａと非圧搾領域５３Ｂとに跨って配置されているため、位置決め部の視認性を高めることができる。位置決め部の視認性を高めることにより、お母さんが赤ちゃんのおむつを装着する際に止着部材を適切に装着し易くなり、また体の大きさに応じてどのくらいの位置につければいいのかを判断しやすくなり、操作性を向上させることができる。 The second printing unit 54B functions as a positioning unit for aligning the position of the fastening member. Since the 2nd printing part which functions as this positioning part extends in the front-back direction and is arranged ranging over pressing field 53A and non-pressing field 53B, it can raise the visibility of a positioning part. By improving the visibility of the positioning part, it will be easier for the mother to wear the fastening member when wearing the baby's diaper, and also determine how much position to put according to the size of the body It becomes easy and operability can be improved.
　また、ターゲット部の面積に対する圧搾領域の面積の比率である圧搾比率は、２０％～５５％が好ましく、より好適には３５％～５０％であることが望ましい。例えば、圧搾比率が２０％よりも低いと、印刷部の視認性が低下するおそれがあり、また止着部材を着脱した際に止着部材のフック部に引っ掛かって抜けてしまう繊維が増えてしまうおそれがある。一方、圧搾比率が５５％よりも高いと、止着部材が引っ掛かり難くなるおそれがある。よって、圧搾比率は、印刷部の視認性や止着部材との掛かり態様を考慮して適宜設定することが望ましい。 Also, the pressing ratio, which is the ratio of the area of the pressing area to the area of the target portion, is preferably 20% to 55%, and more preferably 35% to 50%. For example, if the pressing ratio is lower than 20%, the visibility of the printed part may be reduced, and more fibers are caught by the hook part of the fastening member when the fastening member is attached or detached. There is a fear. On the other hand, if the compression ratio is higher than 55%, the fastening member may not be easily caught. Therefore, it is desirable that the compression ratio is appropriately set in consideration of the visibility of the printing unit and the manner of engagement with the fastening member.
　本実施の形態に係る吸収性物品によれば、使用者は、吸収性物品の外方向外側に配置されたターゲット部を直接視認できるため、シートを介して視認する構成と比較して視認性を向上させることができる。 According to the absorbent article according to the present embodiment, the user can directly visually recognize the target portion disposed on the outer side in the outer direction of the absorbent article. Can be improved.
　印刷部は、メルトブローン不織布層を含む第１不織布層に設けられている。メルトブローン不織布層は、紡糸ノズルから出た樹脂をホットエアーで延伸し、その繊維を捕集するため、長繊維であり、その繊維径が比較的細い。印刷部の着色成分は、細かい繊維間に侵入し、メルトブローン不織布層の内部まで浸透し易くなる。よって、ターゲット部の着色状態を維持し易くなる。また、メルトブローン不織布層は、比較的密度が高いため、着色成分を細かく配置でき、細かい柄を表現することが可能となる。 The printing part is provided in the first nonwoven fabric layer including the meltblown nonwoven fabric layer. The melt blown non-woven fabric layer is a long fiber and has a relatively thin fiber diameter because the fiber from the spinning nozzle is drawn with hot air and the fiber is collected. The coloring component of the printing part penetrates between fine fibers and easily penetrates into the melt blown nonwoven fabric layer. Therefore, it becomes easy to maintain the colored state of the target portion. In addition, since the melt blown nonwoven fabric layer has a relatively high density, the colored components can be finely arranged, and a fine pattern can be expressed.
　更に、吸収性物品の外方向外側に配置される第２不織布層は、スルーエアー不織布層であり、メルトブローン不織布層と比較して嵩高であり、止着部材を止着し易い。また、印刷が施された第１不織布層には止着部材が直接止着しないため、止着部材を繰り返し着脱した場合であっても、印刷部が摩耗することを抑制し、印刷部の表示状態を維持できる。 Furthermore, the 2nd nonwoven fabric layer arrange | positioned on the outer direction outer side of an absorbent article is a through-air nonwoven fabric layer, is bulky compared with a melt blown nonwoven fabric layer, and is easy to fasten a fastening member. In addition, since the fastening member is not directly attached to the printed first nonwoven fabric layer, even when the fastening member is repeatedly attached and detached, it is possible to suppress the printing portion from being worn and display the printing portion. The state can be maintained.
　また、ターゲット部に圧搾部が形成されており、圧搾部が形成された部分の厚みは薄く、かつ光が透過し易い。よって、ターゲット部の印刷部のうち、圧搾部に重なる印刷部の視認性を高めることができる。 Moreover, the pressing part is formed in the target part, the thickness of the part in which the pressing part was formed is thin, and light is easy to permeate | transmit. Therefore, the visibility of the printing part which overlaps with a pressing part among the printing parts of a target part can be improved.
