Description

本発明は、使い捨ての着用物品に関する。 The present invention relates to a disposable wearing article.

従来、前後ウエスト域とクロッチ域とが別体のパネルから形成された使い捨ての着用物品は公知である。例えば、特許文献１には、前後ウエスト域を形成するウエストパネルと、クロッチ域を形成するクロッチパネルとを含む着用物品が開示されている。 Conventionally, disposable wearing articles in which front and rear waist regions and crotch regions are formed from separate panels are known. For example, Patent Document 1 discloses a wearing article including a waist panel that forms a front and back waist region and a crotch panel that forms a crotch region.

特表２００６−５２５８５８号公報JP-T-2006-525858

特許文献１に開示された着用物品では、外面全体が白色の繊維不織布から形成されており、ウエストパネル及びクロッチパネルは非着色であることから、各パネルが重なる領域や各パネルの境界部分において色差が小さく、複数のパネル部材から構成されていることを外観視において視認されることはない。 In the wearing article disclosed in Patent Document 1, the entire outer surface is formed from a white fiber nonwoven fabric, and the waist panel and the crotch panel are non-colored. Is small, and it is not visually recognized that it is composed of a plurality of panel members.

しかし、かかる着用物品は、全体が外観視において白色であるため、全域又はその一部に着色を施した着用物品に比して意匠性に欠ける。また、外面全体が着色されてないことによって、繊維不織布の質感が表れて、使い捨て着用物品らしい外観となる。着用物品の意匠性を向上させて下着らしい外観にするために、ウエストパネル及びクロッチパネルの外面に着色をした場合には、各パネルが重なる部分が他の部分に比して色が濃くなったり、各パネルの境界部分近傍において色差が生じたりして、外観視において複数のパネル部材から構成されていることが認識されて、下着らしい外観が損なわれてしまうおそれがある。 However, since such a worn article is entirely white in appearance, it lacks design properties compared to a worn article in which the entire region or a part thereof is colored. Moreover, when the whole outer surface is not colored, the texture of a fiber nonwoven fabric appears and it becomes the external appearance like a disposable wearing article. When coloring the outer surface of the waist panel and the crotch panel in order to improve the design of the wearing article and make it look like underwear, the part where each panel overlaps may become darker than the other part There may be a color difference in the vicinity of the boundary portion of each panel, and it may be recognized that the panel is composed of a plurality of panel members in appearance, and the appearance of underwear may be impaired.

そこで、本発明の目的は、従来の技術の改良であって、前後ウエスト域と、クロッチ域とが、別体のパネルによって形成される使い捨ての着用物品において、略全域に着色を施して意匠性を向上させるとともに、下着らしい外観を得ることができる着用物品の提供にある。 Accordingly, an object of the present invention is an improvement of the conventional technique, and in a disposable wearing article in which the front and rear waist regions and the crotch region are formed by separate panels, the design is performed by coloring almost the entire region. It is in providing the wearing article which can improve the appearance and can obtain the external appearance like underwear.

上記課題を達成するために、本発明が対象とするのは、縦方向及び横方向と、前ウエスト域と、後ウエスト域と、前記前後ウエスト域の間に位置するクロッチ域とを有し、前記前後ウエスト域を形成する環状のウエストパネルと、前記クロッチ域から前記前後ウエスト域へ延びるクロッチパネルと、ウエスト開口及び一対のレッグ開口とを含む使い捨ての着用物品である。 In order to achieve the above-mentioned problem, the present invention is intended to have a longitudinal direction and a lateral direction, a front waist region, a rear waist region, and a crotch region located between the front and rear waist regions, A disposable wearing article including an annular waist panel forming the front and rear waist region, a crotch panel extending from the crotch region to the front and rear waist region, and a waist opening and a pair of leg openings.

本発明は、上記使い捨ての着用物品において、前記ウエストパネルは、前記横方向に弾性的に伸縮可能なウエスト弾性体を含み、前記ウエストパネルと前記クロッチパネルとは、略全域に着色が施されており、前記ウエストパネルにおいて前記クロッチパネルが平面視において重ならない第１領域と、前記クロッチパネルにおいて前記ウエストパネルが平面視において重ならない第２領域と、前記ウエストパネルと前記クロッチパネルとが平面視において重なる第３領域とのうち、前記ウエスト弾性体が収縮した自然状態において、外観視における色濃度が最も高い領域と最も低い領域との色差が、０．１〜１０．０の範囲であり、前記クロッチパネルは、吸収体と、前記クロッチパネルの非肌対向面を形成する被覆シートと、前記被覆シートと前記吸収体の間に位置し、前記吸収体の非肌対向面側を覆う防漏シートとを含み、前記被覆シートは、白色であって光線透過率が６０％以上の繊維不織布から形成され、前記防漏シートは、着色が施されたプラスチックフィルムから形成され、前記内層シートよりも濃い色に着色されることを特徴とする。 In the disposable wearing article according to the present invention, the waist panel includes a waist elastic body that is elastically stretchable in the lateral direction, and the waist panel and the crotch panel are colored over substantially the entire area. A first region in the waist panel where the crotch panel does not overlap in plan view, a second region in the crotch panel where the waist panel does not overlap in plan view, and the waist panel and the crotch panel in plan view. of the third region overlapping, in a natural state where the waist elastic member is contracted, the color difference between the lowest area and highest region color density in appearance when viewed from, Ri range der of 0.1 to 10.0, The crotch panel includes an absorber, a covering sheet that forms a non-skin facing surface of the crotch panel, and the covering sheet. And a leak-proof sheet that is positioned between the absorbent body and covers the non-skin-facing surface side of the absorbent body, and the covering sheet is formed of a fiber nonwoven fabric that is white and has a light transmittance of 60% or more. The leak-proof sheet is formed of a colored plastic film and is colored in a darker color than the inner layer sheet .

本発明に係る使い捨ての着用物品によれば、ウエストパネルとクロッチパネルとは、略全域に着色が施されているため、着用物品の意匠性が向上する。また、ウエストパネルにおいてクロッチパネルが平面視において重ならない第１領域と、クロッチパネルにおいてウエストパネルが平面視において重ならない第２領域と、ウエストパネルとクロッチパネルとが平面視において重なる第３領域とのうち、ウエスト弾性体が収縮した自然状態において、外観視における色濃度が最も高い領域と最も低い領域との色差が、０．１〜１０．０の範囲であるため、各パネルが重なる領域や各パネルどうしの境界が形成される部分における色差が小さく、下着らしい印象を与えることができる。 According to the disposable wearing article according to the present invention, the waist panel and the crotch panel are colored over substantially the entire area, so that the design of the wearing article is improved. Further, the first region of the waist panel where the crotch panel does not overlap in plan view, the second region of the crotch panel where the waist panel does not overlap in plan view, and the third region where the waist panel and the crotch panel overlap in plan view Among them, in the natural state where the waist elastic body contracts, the color difference between the highest color density region and the lowest color region in appearance is in the range of 0.1 to 10.0. The color difference in the part where the boundary between panels is formed is small, and an impression like underwear can be given.

本実施形態においては、前後ウエストパネル１７，１８のうちの内層シート３１，３２が比較的に薄い色（例えば、淡い青色）に着色されており、クロッチパネル１５のうちの防漏シート５４が比較的に濃い色（内層シート３１，３２に比して濃い色。例えば、内層シート３１，３２に比して濃い青色）に着色されている。着色された内層シート３１，３２を形成する繊維不織布は、それらの自然状態（弾性体が配置されていない状態。弾性体が配置されている場合には、それらが伸長状態された状態。）における外観視において着色された色がほぼ均一になるように、シートの厚さや繊維密度が全体的にほぼ同じである。内層シート３１，３２は、印刷によって着色することが可能であるが、繊維不織布で形成された内層シート３１，３２を着色する場合、原料樹脂に顔料又は染料を添加して構成繊維を着色させることによって、プラスチックフィルムと異なり地合いむらのある繊維不織布であっても、均一に着色させることができる。内層シート３１，３２と防漏シート５４とは、同色又は類似色に着色されており、それらが積層されることによって、該積層領域は、外観視において、いずれかの着色シートが配置された単層領域よりも着色された色が濃くなる。また、内層シート３１，３２よりも防漏シート５４が濃い色に着色されていることから、それらが重ならない領域においては、防漏シート５４の配置された領域が内層シート３１，３２の配置された領域よりも（図２に示す弾性体が伸長された状態において）色合いが濃くなる。 In the present embodiment, the inner layer sheets 31 and 32 of the front and rear waist panels 17 and 18 are colored in a relatively light color (for example, light blue), and the leakproof sheet 54 of the crotch panel 15 is compared. In particular, it is colored in a deep color (darker than the inner layer sheets 31 and 32. For example, it is darker blue than the inner layer sheets 31 and 32). The fiber nonwoven fabrics forming the colored inner layer sheets 31 and 32 are in their natural state (a state in which no elastic body is disposed. In a case where the elastic body is disposed, a state in which they are stretched). The thickness and fiber density of the sheet are almost the same as a whole so that the colored colors are almost uniform in appearance. The inner layer sheets 31 and 32 can be colored by printing, but when the inner layer sheets 31 and 32 formed of a fiber nonwoven fabric are colored, the constituent fibers are colored by adding a pigment or a dye to the raw material resin. Therefore, even a non-woven fiber nonwoven fabric that is uneven, unlike a plastic film, can be uniformly colored. The inner layer sheets 31 and 32 and the leak-proof sheet 54 are colored in the same color or similar color, and by laminating them, the laminated region is a single layer in which any of the colored sheets is arranged in appearance. The colored color becomes darker than the layer area. Further, since the leak-proof sheet 54 is colored darker than the inner-layer sheets 31 and 32, the area where the leak-proof sheet 54 is arranged is arranged in the area where the leak-proof sheets 54 do not overlap. The shade becomes darker than that of the region (when the elastic body shown in FIG. 2 is extended).

着色された内層シート３１，３２は、外層シート３３，３４を透過して視認されるので、外層シート３３，３４は、少なくとも６０％以上の光線透過率を有するものであることが好ましい。また、防漏シート５４は、内外層シート３１〜３４と被覆シート５３とを透過して視認されるものであって、各シート３１〜３４，５３の積層領域の光線透過率は、少なくとも３０％以上であることが好ましい。また、着色された色が外層シート３３，３４に透過されやすいようにするために、内層シート３１，３２の光線透過率は、外層シート３３，３４のそれよりも低いことが好ましい。 Since the colored inner layer sheets 31 and 32 are visible through the outer layer sheets 33 and 34, it is preferable that the outer layer sheets 33 and 34 have a light transmittance of at least 60% or more. The leak-proof sheet 54 is visible through the inner and outer layer sheets 31 to 34 and the covering sheet 53, and the light transmittance of the laminated region of the sheets 31 to 34 and 53 is at least 30%. The above is preferable. Further, in order to make the colored color easily transmitted to the outer layer sheets 33, 34, the light transmittance of the inner layer sheets 31, 32 is preferably lower than that of the outer layer sheets 33, 34.

図１、図４及び図５を参照すると、おむつ１０は、説明の便宜上、ウエストパネル１４においてクロッチパネル１５が平面視において重ならない第１領域６１と、クロッチパネル１５においてウエストパネル１４が平面視において重ならない第２領域６２と、ウエストパネル１４とクロッチパネル１５とが平面視において重なる第３領域６３とに区分される。既述とおり、着色されたシートが配置された領域は、それが外層シート３３，３４から透過されるところ、各弾性体が配設された部分ではギャザーの影響によって繊維が密になって色合いが濃くなる。本実施形態においては、防漏シート５４が内層シート３１，３２よりも濃い色に着色されていることから、前者の配置領域である第２領域６２が後者の配置領域である第１領域６１よりも濃くなるところ、第１領域６１には、前後ウエスト弾性体４１，４２が配設されていることによってそのギャザーの影響で着色された色合いが濃くなり、おむつ１０の自然状態（各弾性体が収縮された状態）及び着用状態（自然状態に比して弾性体が伸長された状態）において、第１領域６１と第２領域６２とは、外観視において、ほぼ同じ濃度の色を有する。 Referring to FIGS. 1, 4, and 5, for convenience of explanation, the diaper 10 includes a first region 61 where the crotch panel 15 does not overlap in the waist panel 14 in the plan view, and the waist panel 14 in the crotch panel 15 in the plan view. A second region 62 that does not overlap and a third region 63 in which the waist panel 14 and the crotch panel 15 overlap in plan view are divided. As described above, in the region where the colored sheet is arranged, the fiber is densely affected by gathers in the portion where each elastic body is arranged when the outer sheet 33, 34 is transmitted. It becomes darker. In this embodiment, since the leak-proof sheet 54 is colored in a darker color than the inner layer sheets 31 and 32, the second area 62 which is the former arrangement area is more than the first area 61 which is the latter arrangement area. In the first region 61, the front and rear waist elastic bodies 41 and 42 are disposed in the first region 61, so that the colored tint is deepened by the influence of the gathers, and the natural state of each diaper 10 (each elastic body is In the contracted state) and in the worn state (the state in which the elastic body is stretched compared to the natural state), the first region 61 and the second region 62 have substantially the same color in appearance.

着色された内層シート３１，３２と防漏シート５４とが重なる第３領域６３は、各領域６１〜６３のうちで最も色濃度が高い領域となる。しかし、比較的に色濃度の低い内層シート３１，３２の位置する第１領域６１を前後ウエスト弾性体４１，４２による収縮作用によって色濃度を高くし、かつ、第３領域６３においては前後ウエスト弾性体４１，４２を配置しない非弾性域を形成し、その色濃度が高くならないようにしていることから、第１〜第３領域６１〜６３間における色差は大きく相違するものではない。本実施形態に係るおむつ１０では、本来的には比較的に濃い色に着色された防漏シート５４の配置された第２領域６２が比較的に薄い色に着色された内層シート３１，３２が配置された第１領域６１よりも色濃度が高くなるべきところ、おむつ１０の外面にギャザーが形成された自然状態において、第１領域６１と第２領域６２との色濃度がほぼ等しくなっている。これは、第１領域６１においてギャザーの形成によって繊維が密になることによるものと考えられる。なお、各領域６１〜６３の色差が所定の範囲内にある限りにおいて、第１領域６１における前後ウエスト弾性体４１，４２の収縮力を調整することによって、第１領域６１の色濃度が第２及び第３領域６２，６３の色濃度よりも高くなることも考えられる。 The third region 63 where the colored inner layer sheets 31 and 32 and the leak-proof sheet 54 overlap is the region having the highest color density among the regions 61 to 63. However, the first region 61 in which the inner layer sheets 31 and 32 having a relatively low color density are positioned has a high color density by the contracting action of the front and rear waist elastic bodies 41 and 42, and the third region 63 has the front and back waist elasticity. Since an inelastic region where the bodies 41 and 42 are not arranged is formed so that the color density is not increased, the color difference between the first to third regions 61 to 63 is not greatly different. In the diaper 10 according to the present embodiment, the inner layer sheets 31 and 32 in which the second region 62 where the leak-proof sheet 54 that is originally colored in a relatively dark color is disposed are colored in a relatively light color. Where the color density should be higher than that of the arranged first area 61, the color densities of the first area 61 and the second area 62 are substantially equal in a natural state where gathers are formed on the outer surface of the diaper 10. . This is thought to be due to the fibers becoming dense in the first region 61 due to the formation of gathers. In addition, as long as the color difference of each area | region 61-63 exists in the predetermined range, the color density of the 1st area | region 61 is set to 2nd by adjusting the contraction force of the front-and-back waist elastic bodies 41 and 42 in the 1st area | region 61. In addition, the color density of the third regions 62 and 63 may be higher.

各弾性体が収縮した自然状態において、第１〜第３領域６１，６２，６３のうち、外観視において、最も色濃度が高い領域と最も色濃度の低い領域との色差（ΔＥ^＊ａｂ）は、Ｌ^＊ａ^＊ｂ^＊表色系において、０．１〜１０．０の範囲である。おむつ１０に下着のような印象を与えるためには、各領域６１〜６３が外観視において同じ色（実質的に色差が０）であることが好ましいが、少なくとも各領域６１〜６３の着色を有する領域の色差（ΔＥ^＊ａｂ）が０．１〜１０．０の範囲内であることが本発明の効果を奏するうえで好ましい。ここで、外観視において最も色濃度が高い領域とは、着色が施されている第１〜第３領域のうち、自然状態において、外観視における着色の濃度が最も高い部分を有する領域をいい、外観視において最も色濃度が低い領域とは、着色が施されている第１〜第３領域のうち、自然状態において外観視における着色の濃度が最も低い部分を有する領域をいう。Ｌ^＊ａ^＊ｂ^＊表色系における色差（ΔＥ^＊ａｂ）は、ΔＥ^＊ａｂ＝（ΔＬ^＊2＋Δａ^＊2＋Δｂ^＊2）^1/2に基づいて計算することができる。 In the natural state in which each elastic body contracts, the color difference (ΔE ^* ab) between the region with the highest color density and the region with the lowest color density in the external appearance among the first to third regions 61, 62, 63. In the L ^* a ^* b ^* color system, the range is 0.1 to 10.0. In order to give the diaper 10 an impression like underwear, it is preferable that the regions 61 to 63 have the same color (substantially no color difference) in appearance, but at least the regions 61 to 63 are colored. The color difference (ΔE ^* ab) of the region is preferably in the range of 0.1 to 10.0 for achieving the effects of the present invention. Here, the region having the highest color density in appearance is a region having the highest coloring concentration in appearance in the natural state among the first to third regions that are colored. The region having the lowest color density in appearance is a region having the portion with the lowest color density in appearance in the natural state among the first to third regions that are colored. The color difference (ΔE ^* ab) in the L ^* a ^* b ^* color system can be calculated based on ΔE ^* ab = (ΔL ^{* 2} + Δa ^{* 2} + Δb ^{* 2} ) ^1/2 .

本実施形態に係るおむつ１０は、前後ウエストパネル１７，１８とクロッチパネル１５とから構成されており、下着らしい印象を与えるためにおむつ１０全体を着色したとしても、各領域６１〜６３の色差によってそれらのパネルどうしの境界部分が視認されて下着らしい外観が損なわれるおそれがあるところ、各領域６１，６２，６３の色差をいずれも１０．０以下とすることで、各パネルの境界部分における色濃度がほぼ均一になり、下着らしい印象を与えることができる。 The diaper 10 according to the present embodiment is composed of the front and rear waist panels 17 and 18 and the crotch panel 15, and even if the entire diaper 10 is colored to give an impression like underwear, the color difference between the regions 61 to 63 is different. There is a possibility that the appearance of underwear may be damaged by visually recognizing the boundary between the panels. By setting the color difference of each of the regions 61, 62, and 63 to 10.0 or less, the color at the boundary of each panel The density is almost uniform, giving an impression of underwear.

特に、おむつの正面視及び背面視において、前後ウエストパネル１７，１８とクロッチパネル１５との境界部分を形成する前後ウエストパネル１７，１８の内端縁１７ｂ，１８ｂは、継ぎ目のように目立つ部分であって、該部分の外形輪郭が明瞭に視認されることによって下着らしい外観が損なわれて、よりおむつとして認識されるおそれがあるが、該境界部分における色差が所定の範囲内にあることによって、おむつ１０の外観視において目立つことはなく、全体として下着のような印象を与えることができる。 In particular, the inner end edges 17b and 18b of the front and rear waist panels 17 and 18 forming the boundary between the front and rear waist panels 17 and 18 and the crotch panel 15 in a front view and a rear view of the diaper are conspicuous portions such as joints. Then, the appearance that seems to be underwear is impaired by the visual recognition of the outer contour of the part clearly, and there is a possibility that it may be recognized as a diaper, but the color difference in the boundary part is within a predetermined range, The appearance of the diaper 10 is not noticeable, and an overall impression of underwear can be given.

既述のとおり、防漏シート５４は内層シート３１，３２よりも色濃度が高くなるように着色されていることから、おむつ１０の最大伸長時における各領域６１，６２，６３の色濃度の相関関係は、第３領域６３＞第２領域６２＞第１領域６１となっている。また、おむつ１０の最大伸長時において、第１領域６１と第２領域６２の色差（おむつ１０を伸長させた状態において肌対向面側に白色の設置板を配置して測定したときの値）は、１０．０以下であることが好ましい。 As described above, since the leak-proof sheet 54 is colored so as to have a higher color density than the inner layer sheets 31 and 32, the correlation between the color densities of the regions 61, 62, and 63 when the diaper 10 is fully extended. The relationship is such that the third region 63> the second region 62> the first region 61. Moreover, at the time of the maximum expansion | extension of the diaper 10, the color difference (The value when arrange | positioning and measuring a white installation board on the skin opposing surface side in the state which extended the diaper 10) of the 1st area | region 61 and the 2nd area | region 62 is It is preferable that it is 10.0 or less.

第３領域６３は、前後ウエスト弾性体４１，４２及び臀部弾性体４３の収縮力が作用する両側部６４と、両側部６４の間に位置し、各弾性体４１，４２，４３の収縮力が実質的に作用しない中央部６５とを有する。第３領域６３の両側部６４において、前後ウエスト弾性体４１，４２及び臀部弾性体４３は、吸収体１６の両側縁部１６ｃに延在しており、その収縮作用によって両側縁部１６ｃの色濃度が比較的に高くなるおそれがあるところ、吸収体１６がシート部材に比して高い剛性を有することからギャザーが形成され難くなり、両側縁部１６ｃの位置する領域において、ギャザーが形成された第３領域６３の他領域に比して色濃度が大きく高くなることはない。また、両側縁部１６ｃの横方向Ｘ外側においては、剛性の変化によって弾性体の応力が集中して細かいギャザーが形成されており、着色されていない白色の外層シート３３，３４を構成する繊維の密度が高くなる。そのため、両側縁部１６ｃ近傍における第１領域６１と第３領域６３との色差による変化が抑えられ、吸収体１６の外形輪郭がはっきりと視認されず、クロッチパネル１５及び吸収体１６の存在を明瞭に把握されることはなく、下着のような外観を損なうおそれはない。 The third region 63 is located between the side portions 64 on which the contracting forces of the front and rear waist elastic bodies 41 and 42 and the buttocks elastic body 43 act, and the contracting forces of the elastic bodies 41, 42, and 43. And a central portion 65 that does not substantially act. In both side portions 64 of the third region 63, the front and rear waist elastic bodies 41 and 42 and the buttocks elastic body 43 extend to the both side edge portions 16c of the absorber 16, and the color density of the both side edge portions 16c by the contraction action thereof. However, since the absorber 16 has higher rigidity than the sheet member, it is difficult to form the gathers, and the gathers are formed in the regions where the side edges 16c are located. Compared with the other areas of the three areas 63, the color density is not greatly increased. Further, on the outer side in the lateral direction X of both side edge portions 16c, the stress of the elastic body is concentrated due to the change in rigidity to form fine gathers, and the fibers constituting the uncolored white outer layer sheets 33 and 34 are formed. Density increases. Therefore, a change due to the color difference between the first region 61 and the third region 63 in the vicinity of both side edge portions 16c is suppressed, the outer contour of the absorber 16 is not clearly seen, and the existence of the crotch panel 15 and the absorber 16 is clear. Will not be detected, and there is no risk of damaging the appearance of underwear.

第１領域６１における各弾性域は、既述した伸長応力の相関関係を有している。伸長応力の高い領域では、ギャザーが密に形成され色濃度が高くなるため、第１領域６１における色濃度の相関関係は、自然状態において、前後第２弾性域４５Ｂ，４６Ｂ≧前後第１弾性域４５Ａ，４６Ａ＞前後第３弾性域４５Ｃ，４６Ｃ＞臀部弾性域４７となっており、臀部弾性域４７と第３領域６３の両側部６４と色差は１０．０以下である。 Each elastic region in the first region 61 has the correlation of the elongation stress described above. Since the gathers are densely formed and the color density is high in the region where the tensile stress is high, the correlation between the color densities in the first region 61 is, in the natural state, the front and rear second elastic regions 45B and 46B ≧ the front and rear first elastic regions. 45A, 46A> front and rear third elastic regions 45C, 46C> collar elastic region 47, and the color difference between the collar elastic region 47 and both side portions 64 of the third region 63 is 10.0 or less.

このように、第１領域６１において色濃度が異なる領域が形成されるおそれがあるところ、前後第１弾性域４５Ａ，４６Ａの肌対向面は、白色（非着色）のシートである延出部（補助シート）３３ａ，３４ａによって覆われていることによって光線透過率が低くなって他の領域との色差が小さくなる。 As described above, there is a possibility that regions having different color densities may be formed in the first region 61, and the skin facing surfaces of the front and rear first elastic regions 45A and 46A are extended portions that are white (non-colored) sheets ( Auxiliary sheets) 33a and 34a cover the light, thereby reducing the light transmittance and reducing the color difference from other regions.

また、前後第３弾性域４５Ｃ，４６Ｃには、クロッチパネル１５の前後端縁２０ａ，２０ｂが配置され、第１領域６１と第３領域６３との境界部分が形成され、外観視において色差が識別されやすくなる。既述したとおり、該弾性域４５Ｃ，４６Ｃの肌対向面側にはクロッチパネル１５の前後端縁２０ａ，２０ｂを覆うように白色（非着色）の補助シート３５，３６が配置されているため、補助シート３５，３６によって光線透過率が低くなって他の領域との色差が小さくなる。 Further, the front and rear end edges 20a and 20b of the crotch panel 15 are arranged in the front and rear third elastic regions 45C and 46C, and a boundary portion between the first region 61 and the third region 63 is formed, and the color difference is discriminated in appearance. It becomes easy to be done. As already described, since the white (non-colored) auxiliary sheets 35 and 36 are arranged so as to cover the front and rear end edges 20a and 20b of the crotch panel 15 on the skin facing surface side of the elastic regions 45C and 46C, The auxiliary sheets 35 and 36 reduce the light transmittance and reduce the color difference from other regions.

図１及び図２を参照すると、防漏カフ（遠位縁部５８ｂ）は、白色の被覆シート５３によって形成されており、遠位縁部５８ｂと吸収体１６の両側縁部１６ｃとの間には、着色された防漏シート５４の一部が露出している。おむつ１０の着用時において、防漏カフの一部が折れ曲がったり捩れたりした状態のままレッグ開口２２に脚を挿入したときには、防漏カフに脚先が引っ掛かったり排泄物の横漏れの原因となるおそれがあることから、着用者は、着用する前にウエスト開口２１を拡げておむつ１０の内面を確認することがある。かかる場合において、防漏シート５４と防漏カフを形成する被覆シート５３とが同色（白色）の場合にはそれらを視覚的に識別することができないおそれがあるところ、本実施形態においては、おむつ１０の内面視において被覆シート５３の遠位縁部５８ｂに隣接する防漏シート５４が着色されていることによって、それらの色彩の相違（コントラスト）によって、防漏カフの形状をはっきりと視認でき、着用する前に安定的に起立できるような態様に修正することができる。 Referring to FIGS. 1 and 2, the leak-proof cuff (distal edge 58 b) is formed by a white covering sheet 53, and between the distal edge 58 b and both side edges 16 c of the absorbent body 16. A part of the colored leak-proof sheet 54 is exposed. When the diaper 10 is worn, if a leg is inserted into the leg opening 22 while a part of the leak-proof cuff is bent or twisted, the tip of the leg may be caught by the leak-proof cuff or cause side leakage of excrement. Since there exists a possibility, a wearer may confirm the inner surface of the diaper 10 by expanding the waist opening 21 before wearing. In such a case, if the leakproof sheet 54 and the covering sheet 53 forming the leakproof cuff are the same color (white), there is a possibility that they cannot be visually identified. In this embodiment, the diaper When the leakproof sheet 54 adjacent to the distal edge portion 58b of the covering sheet 53 is colored in the inner surface view of FIG. 10, the shape of the leakproof cuff can be clearly recognized due to the difference in color (contrast). It can correct | amend to the aspect which can stand stably before wearing.

本実施形態においては、前後ウエストパネル１７，１８において、内外層シート３１〜３４のうちの内層シート３１，３２を着色シートとしたが、おむつ１０の外観視において、着色された色が視認される限りにおいて、内層シート３１，３２と外層シート３３，３４とのうちの少なくとも一方のシートが着色されていればよい。また、クロッチパネル１５のうちの防漏シート５４を着色シートとしたが、防漏シート５４ではなく、被覆シート５３が着色されていてもよいし、両シート５３，５４が着色されていてもよい。このように、前後ウエストパネル１７，１８及びクロッチパネル１５において、単数、複数を問わず、それを構成するシート部材のうちのいずれかを着色シートとすることによって、おむつ１０の自然状態及び着用状態において、第１〜第３領域６１〜６３の色差を所定の範囲内とすることができる。なお、第１〜第３領域６１〜６３の色差は、少なくともおむつ１０の自然状態において０．１〜１０．０の範囲であればよい。 In the present embodiment, in the front and rear waist panels 17 and 18, the inner layer sheets 31 and 32 of the inner and outer layer sheets 31 to 34 are colored sheets. However, in the appearance of the diaper 10, the colored color is visually recognized. As long as at least one of the inner layer sheets 31 and 32 and the outer layer sheets 33 and 34 is colored. Moreover, although the leak-proof sheet 54 in the crotch panel 15 is a colored sheet, the cover sheet 53 may be colored instead of the leak-proof sheet 54, or both sheets 53 and 54 may be colored. . Thus, in the front and rear waist panels 17 and 18 and the crotch panel 15, regardless of whether the sheet member is a colored sheet, the natural state and the worn state of the diaper 10 are used. The color difference between the first to third regions 61 to 63 can be within a predetermined range. In addition, the color difference of the 1st-3rd area | regions 61-63 should just be the range of 0.1-10.0 in the natural state of the diaper 10 at least.

＜第２実施形態＞
本実施形態に係るおむつ１０の基本構成は、第１実施形態と同様であるので、相違する構成についてのみ以下に説明する。 Second Embodiment
Since the basic configuration of the diaper 10 according to the present embodiment is the same as that of the first embodiment, only different configurations will be described below.

図６〜図８を参照すると、本実施形態に係るおむつ１０では、前後ウエストパネル１７，１８において、内層シート３１，３２に着色が施されており、外層シート３３，３４は非着色（白色）であって、光線透過率が約６０％以上である。また、内外層シート３１，３２，３３，３４の間には、おむつ１０の外部（外層シート２３，２４の外側）から視認可能な装飾要素７３が印刷された中間シート７１，７２が配置される。 With reference to FIGS. 6 to 8, in the diaper 10 according to the present embodiment, the front and rear waist panels 17 and 18 are colored on the inner layer sheets 31 and 32, and the outer layer sheets 33 and 34 are not colored (white). The light transmittance is about 60% or more. Between the inner and outer layer sheets 31, 32, 33, and 34, intermediate sheets 71 and 72 on which a decorative element 73 that is visible from the outside of the diaper 10 (outside the outer layer sheets 23 and 24) is printed are disposed. .

中間シート７１，７２は、略矩形状であって、横方向Ｘに延びて縦方向Ｙにおいて離間対向する内端縁７１ａ，７２ａ及び外端縁７１ｂ，７２ｂと、内外端縁７１ａ，７１ｂ，７２ａ，７２ｂ間を縦方向Ｙに延びる両側縁７１ｃ，７２ｃとを有する。内端縁７１ａ，７２ｂは前後ウエストパネル１７，１８の内端縁１７ａ，１８ａとほぼ一致しており、外端縁７１ｂ，７２ｂは、吸収体１６の縦方向Ｙ外側に位置し、本実施形態ではクロッチパネル１５の前後端縁２０ａ，２０ｂとほぼ一致している。両側縁７１ｃ，７２ｃは第３領域６３の両側部６４に位置している。 The intermediate sheets 71 and 72 have a substantially rectangular shape, and extend in the horizontal direction X and are opposed to each other in the vertical direction Y. The inner end edges 71a and 72a and the outer end edges 71b and 72b, and the inner and outer end edges 71a, 71b, and 72a. , 72b and both side edges 71c, 72c extending in the vertical direction Y. The inner end edges 71a and 72b substantially coincide with the inner end edges 17a and 18a of the front and rear waist panels 17 and 18, and the outer end edges 71b and 72b are located on the outer side in the longitudinal direction Y of the absorber 16, and in this embodiment. Then, it almost coincides with the front and rear edges 20a, 20b of the crotch panel 15. Both side edges 71 c and 72 c are located on both side portions 64 of the third region 63.

中間シート７１，７２は、不透液性の繊維不織布、不透液性かつ透湿性のプラスチックフィルム又はそれらのラミネートシートから形成される。本実施形態では装飾要素７３の一例として、動物を模したキャラクターの図柄が示されているが、外部から視認されてその形態が把握できる限りにおいて、各種公知の図形、装飾模様、絵柄、文字、記号、着色等であってもよい。中間シート７１，７２において装飾要素７３を除く領域（以下、非装飾領域７４という）には、内層シート３１，３２と同色に着色が施されている。非装飾領域７４は、印刷や有彩色の顔料を添加することにより着色することができる。中間シート７１，７２の非装飾領域７４における光線透過率は、約５〜５０％である。 The intermediate sheets 71 and 72 are formed from a liquid-impervious fiber nonwoven fabric, a liquid-impervious and moisture-permeable plastic film, or a laminate sheet thereof. In the present embodiment, as an example of the decorative element 73, a character pattern imitating an animal is shown. However, as long as the form can be grasped by being visually recognized from the outside, various known graphics, decorative patterns, patterns, characters, It may be a symbol, coloring or the like. In the intermediate sheets 71 and 72, the region excluding the decorative element 73 (hereinafter referred to as the non-decorative region 74) is colored in the same color as the inner layer sheets 31 and 32. The non-decoration region 74 can be colored by printing or adding a chromatic pigment. The light transmittance in the non-decorative region 74 of the intermediate sheets 71 and 72 is about 5 to 50%.

第２実施形態のおむつ１０において、装飾要素７３を除く領域では、各弾性体が収縮した自然状態において、第１、第２及び第３領域６１，６２，６３のうち、外観視において、色濃度が最も高い領域と最も低い領域との色差（ΔＥ^＊ａｂ）は、Ｌ^＊ａ^＊ｂ^＊表色系において０．１〜１０．０の範囲である。第３領域６３では、中間シート７１，７２が配置されている領域において、中間シート７１，７２の非装飾領域７４、内層シート３１，３２、及び防漏シート５４が重なることにより、色濃度が最も高くなっており、具体的には、第３領域６３の非装飾領域７４と、他の領域との色差が０．１〜１０．０の範囲にある。 In the diaper 10 of the second embodiment, in the region excluding the decorative element 73, in the natural state in which each elastic body contracts, the color density in the external appearance among the first, second, and third regions 61, 62, 63. The color difference (ΔE ^* ab) between the highest and lowest regions is in the range of 0.1 to 10.0 in the L ^* a ^* b ^* color system. In the third region 63, the color density is the highest in the region where the intermediate sheets 71 and 72 are arranged by overlapping the non-decorative region 74, the inner layer sheets 31 and 32, and the leak-proof sheet 54 of the intermediate sheets 71 and 72. Specifically, the color difference between the non-decoration area 74 of the third area 63 and other areas is in the range of 0.1 to 10.0.

このように、おむつ１０の装飾要素７３を除く領域において、各領域６１，６２，６３の色差をいずれも１０．０以下とすることで、外観視において各パネルの境界部分における色濃度がほぼ均一になり、下着らしい印象を与えることができる。また、外層シート３４，３５を非着色とし、光線透過率を６０％以上とすることで、おむつ１０の外面から装飾要素７３を明瞭に視認することができ、より意匠性の高いおむつ１０とすることができる。 In this way, in the area excluding the decorative element 73 of the diaper 10, the color differences of the areas 61, 62, and 63 are all 10.0 or less, so that the color density at the boundary portion of each panel is almost uniform in appearance. And give an impression of underwear. Moreover, the decoration element 73 can be clearly visually recognized from the outer surface of the diaper 10 by making the outer layer sheets 34 and 35 uncolored and setting the light transmittance to 60% or more, thereby making the diaper 10 having higher design. be able to.

＜変形例＞
図９及び図１０を参照すると、第２実施形態の変形例におけるおむつ１０では、後ウエストパネル１８における中間シート７２が後ウエスト部２３にのみ配置されており、臀部カバー部２４に配置されていない。つまり、後ウエストパネル１８における第３領域６３では、中間シート７２が配置されたフィルム積層域７６と、臀部カバー部２４に位置し、中間シート７２が配置されていない非フィルム積層域７７とが形成される。中間シート７２は、非装飾領域７４に着色が施されているため、第３領域６３の色濃度はフィルム積層域７６で最も高くなり、第２領域６２を含めた色濃度の相関関係は、おむつ１０の自然状態において、フィルム積層域７６＞非フィルム積層域７７＞第２領域６２となる。つまり、装飾要素７３を除く領域において、フィルム積層域７６と非フィルム積層域７７及び第２領域６２と非フィルム積層域７７との色差は、フィルム積層域７６と第２領域６２との色差よりも小さくなる。かかるおむつ１０では、フィルム積層域７６から第２領域６２に向かって色濃度が薄くなるように色のグラデーションが生じて、非フィルム積層域７７を形成しないものに比して色差が認識されにくくなり、より全体が均一に着色されたおむつ１０として認識させることができる。 <Modification>
Referring to FIGS. 9 and 10, in the diaper 10 according to the modified example of the second embodiment, the intermediate sheet 72 in the rear waist panel 18 is disposed only in the rear waist portion 23 and is not disposed in the buttock cover portion 24. . That is, in the third region 63 in the rear waist panel 18, a film lamination region 76 in which the intermediate sheet 72 is disposed and a non-film lamination region 77 in which the intermediate sheet 72 is not disposed, which is located in the collar cover portion 24, are formed. Is done. Since the intermediate sheet 72 is colored in the non-decoration area 74, the color density of the third area 63 is highest in the film lamination area 76, and the correlation of the color density including the second area 62 is a diaper. In the 10 natural states, film lamination area 76> non-film lamination area 77> second area 62. That is, in the area excluding the decorative element 73, the color difference between the film lamination area 76 and the non-film lamination area 77 and the second area 62 and the non-film lamination area 77 is larger than the color difference between the film lamination area 76 and the second area 62. Get smaller. In such a diaper 10, a color gradation is generated so that the color density decreases from the film lamination area 76 toward the second area 62, and the color difference is less likely to be recognized as compared with the case where the non-film lamination area 77 is not formed. Thus, the diaper 10 can be recognized more uniformly as a whole.

なお、第２実施形態及び変形例において、中間シート７１，７２の非装飾領域７４を無色透明とすることもできる。かかるおむつ１０では、第３領域６３の装飾要素７３を除く領域において、中間シート７１，７２の配置領域と、非配置領域との色差が１に近い値となり、より下着らしい印象を与えることができる。また、上記実施形態及び変形例では、クロッチパネル１５が内層シート３１，３２の肌対向面側に配置されているが、クロッチパネル１５を内層シート３１，３２と中間シート７１，７２の間に配置する構成としてもよい。第１及び第２実施形態並びに変形例において、おむつ１０の略全域が外観視において視認可能な着色を有するとは、おむつ１０の外面（非肌対向面）において、非装飾領域７４を除く約９０％以上、好ましくは約９５％以上、より好ましくは約９８％以上の領域が外観視において視認可能な着色を有することをいう。 In the second embodiment and the modification, the non-decoration region 74 of the intermediate sheets 71 and 72 can be made colorless and transparent. In the diaper 10, the color difference between the arrangement area of the intermediate sheets 71 and 72 and the non-arrangement area is a value close to 1 in the area of the third area 63 excluding the decorative element 73, and a more underwear-like impression can be given. . Moreover, in the said embodiment and modification, although the crotch panel 15 is arrange | positioned at the skin opposing surface side of the inner layer sheets 31 and 32, the crotch panel 15 is arrange | positioned between the inner layer sheets 31 and 32 and the intermediate | middle sheets 71 and 72. It is good also as composition to do. In the first and second embodiments and the modifications, the fact that the substantially entire region of the diaper 10 has a color that can be visually recognized in appearance is that the outer surface (non-skin facing surface) of the diaper 10 is approximately 90 excluding the non-decorative region 74. % Or more, preferably about 95% or more, and more preferably about 98% or more of the region has a color that is visible in appearance.
