Description

本発明は、展開型使い捨ておむつ等の、止着用のファスニングテープを所定の止着領域に止着することで装着するタイプの展開型着用物品に関する。 The present invention relates to a deployable wearing article such as a deployable disposable diaper that is attached by fastening a fastening tape for fastening to a predetermined fastening region.

展開型着用物品は、前身頃と後身頃を一体化させる締結手段を備えており、この締結手段として従来、止着と剥離とが自在に行える機械的な接合を可能とするファスニングテープが用いられている。例えば、展開型着用物品の一種である展開型使い捨ておむつは、着用者の腹側に配される腹側部及び背側に配される背側部並びにそれらの間に位置する股下部を有し、これを着用する際には、背側部の両側縁部を着用者の腹側に引き延ばし、その両側縁部に設けられたファスニングテープの止着部を腹側部の外面に止着する。これにより、おむつを腰周りで適度に締め付け、ずれ落ちないように固定することができる。ファスニングテープは、典型的には、ファスニングテープの主体をなすベース基材にフック材などからなる止着部が取り付けられた構成を有し、展開型使い捨ておむつにおいては、該ベース基材の一部が該おむつのフラップ部に固定され、該ベース基材の残りの部分が該フラップ部から延出するように取り付けられる。 The deployable wearing article is provided with a fastening means for unifying the front body and the back body, and conventionally, as this fastening means, a fastening tape which enables mechanical joining which can be freely attached and detached is used. ing. For example, a deployable disposable diaper, which is a type of deployable wear article, has an abdominal part disposed on the ventral side of the wearer, a dorsal part disposed on the dorsal side, and a crotch portion located therebetween. When wearing this, the both side edges of the back side are extended to the wearer's abdominal side, and the fastening portions of the fastening tape provided on the both side edges are fastened to the outer surface of the abdominal side. As a result, the diaper can be appropriately tightened around the waist and fixed so as not to slip off. The fastening tape typically has a structure in which a fastening portion made of a hook material or the like is attached to a base material that is the main body of the fastening tape, and in a deployable disposable diaper, a part of the base material is used. Is fixed to the flap portion of the diaper, and the remaining portion of the base substrate is attached so as to extend from the flap portion.

特許文献１には、展開型使い捨ておむつにおけるファスニングテープについて、その風合いや見た目の違和感を大幅に軽減しつつ充分な係合力を有するようにすることを目的として、ファスニングテープを、不織布によって形成された基材シートと、複数の係合フックが設けられたフックシートとから構成し、該フックシートが存在する領域のＫＥＳ曲げ剛性値を特定値以下に設定することが記載されている。 Patent Document 1 discloses a fastening tape formed of a non-woven fabric for the purpose of providing a sufficient fastening force for a fastening tape in a deployable disposable diaper while significantly reducing the texture and discomfort of the appearance. It is described that a base sheet and a hook sheet provided with a plurality of engaging hooks are provided, and a KES bending rigidity value in a region where the hook sheet exists is set to a specific value or less.

展開型着用物品に取り付けられたファスニングテープのベース基材は、一般的に肌触りや着用者の肌に当たった場合の傷付きを考慮し、不織布などの比較的柔らかい素材が用いられる。ベース基材を柔らかくすることで感触がよくなり、肌への傷付きも防ぐことができる。しかし、ベース基材を柔らかくすると、ファスニングテープが折れやすくなり、「意図しない折れ」が多発して、ファスニングテープの操作性や着用物品の着用感に悪影響が出るおそれがある。例えば図１２に示すように、ファスニングテープ５に対し、縦方向Ｘの両側から外力Ｆがかかると、その外力Ｆがさほど大きなものではない場合でも、ファスニングテープ５自体が柔らかく曲がりやすいものであるため、ファスニングテープ５が、その縦方向Ｘの中央を通って横方向Ｙに延びる可撓軸ＦＳに沿って縦方向Ｘに折れやすく、ファスニングテープ５全体がおしつぶされたように変形しやすい。なお、縦方向Ｘは、ファスニングテープを備える展開型着用物品の着用者の前後方向に対応する方向であり、横方向Ｙは、縦方向Ｘに直交する方向であり、ファスニングテープの物品本体からの延出方向である。 The base material of the fastening tape attached to the deployable wear article is generally made of a relatively soft material such as a non-woven fabric in consideration of touch and scratches when the wearer's skin is hit. Softening the base material improves the feel and prevents damage to the skin. However, if the base material is softened, the fastening tape is likely to be broken, and "unintentional folding" occurs frequently, which may adversely affect the operability of the fastening tape and the wearing feeling of the worn article. For example, as shown in FIG. 12, when an external force F is applied to the fastening tape 5 from both sides in the vertical direction X, the fastening tape 5 itself is soft and easily bent even if the external force F is not so large. The fastening tape 5 easily breaks in the vertical direction X along the flexible axis FS extending in the horizontal direction Y through the center of the vertical direction X, and the entire fastening tape 5 is easily deformed as if it was squashed. In addition, the longitudinal direction X is a direction corresponding to the front-back direction of the wearer of the deployable wearing article including the fastening tape, and the lateral direction Y is a direction orthogonal to the longitudinal direction X, which is from the article body of the fastening tape. It is the extension direction.

このようなファスニングテープの意図しない折れが発生すると、折れ線を挟んで縦方向の両側に位置する止着部どうしがくっついてしまい、ファスニングテープの止着操作が困難になるおそれがある。また例えば、展開型着用物品の着用中に着用者が前屈みの姿勢をとった場合に、該展開型着用物品の腹側で止着領域に止着されているファスニングテープに図１１に示す如き意図しない折れが発生し、着用感が低下するおそれがある。ファスニングテープが薄く柔軟でありながらも保形性に優れ、前記の意図しない折れが生じ難い展開型着用物品は未だ提供されていない。 If such an unintended fold of the fastening tape occurs, the fastening portions located on both sides in the longitudinal direction of the fastening tape may stick to each other and the fastening operation of the fastening tape may become difficult. In addition, for example, when the wearer takes a forward bending posture while wearing the deployable wearing article, the fastening tape secured to the fastening region on the ventral side of the deployable wearing article has an intention as shown in FIG. Doing so may cause breakage and reduce the wearing comfort. A deployable wearing article in which the fastening tape is thin and flexible but has an excellent shape-retaining property and in which unintentional folding is unlikely to occur is not yet provided.

したがって本発明の課題は、ファスニングテープの保形性に優れ、意図しない折れが生じ難い展開型着用物品を提供することに関する。 Therefore, an object of the present invention is to provide a deployable wearing article which is excellent in shape retaining property of the fastening tape and in which unintentional bending hardly occurs.

本発明は、着用者の前後方向に対応する縦方向とこれに直交する横方向とを有し、物品本体と、該物品本体の縦方向に沿う両側縁部に設けられたファスニングテープとを具備する展開型着用物品であって、前記ファスニングテープは、ベース基材と、該ベース基材を他の部材に止着する止着部とを具備し、平面視で前記物品本体と重なり、該物品本体に固定された本体重複部と、該物品本体から延出し、該物品本体に対して非固定の延出部とに区分され、前記延出部において、前記ベース基材の片面に前記止着部が設置されているとともに、前記ファスニングテープの折り畳みに使用される折り目が該ベース基材を縦方向に縦断しており、前記延出部の前記ベース基材における前記止着部の設置面とは反対側の面に、外層シートが接合され、該外層シートと該ベース基材との接合部が、前記折り目の横方向両側にて縦方向に連続している展開型着用物品である。 The present invention has a vertical direction corresponding to the front-back direction of the wearer and a horizontal direction orthogonal thereto, and comprises an article body and fastening tapes provided on both side edges along the article body in the longitudinal direction. Wherein the fastening tape includes a base material and a fastening portion that fastens the base material to another member, and the fastening tape overlaps with the article body in a plan view. It is divided into a main body overlapping portion fixed to the main body and an extension portion that extends from the article body and is not fixed to the article body, and the fastening portion is attached to one surface of the base substrate at the extension portion. And a fold line used for folding the fastening tape longitudinally cuts the base material in the longitudinal direction, and the installation surface of the fastening portion in the base material of the extending portion and Is a development-type wearing article in which an outer layer sheet is joined to the surface on the opposite side, and joints between the outer layer sheet and the base material are continuous in the longitudinal direction on both lateral sides of the fold.

本発明によれば、ファスニングテープの保形性に優れ、意図しない折れが生じ難い展開型着用物品が提供される。本発明の展開型着用物品によれば、感触や肌への傷付き防止等の観点から、ファスニングテープを比較的柔らかく曲げやすいものとした場合でも、そのファスニングテープは保形性に優れ、意図しない折れが生じ難いため、ファスニングテープの止着操作や剥離操作をスムーズに行うことができ、また、着用中にファスニングテープの折れに起因して着用感が低下する不都合が効果的に防止される。 ADVANTAGE OF THE INVENTION According to this invention, the deployable wearing article which is excellent in the shape-retaining property of the fastening tape and in which unintentional bending hardly occurs is provided. According to the deployable wearing article of the present invention, from the viewpoint of touch and prevention of damage to the skin, even when the fastening tape is made relatively soft and easy to bend, the fastening tape has excellent shape retention and is not intended. Since it is hard to break, the fastening operation and the peeling operation of the fastening tape can be smoothly performed, and the inconvenience that the wearing feeling is deteriorated due to the breaking of the fastening tape during wearing is effectively prevented.

A nonwoven fabric is preferable as the base material 50 from the viewpoints of imparting flexibility to the fastening tape 5 and making it feel good, and preventing damage to the skin when the fastening tape 5 touches the skin. As the nonwoven fabric used for the base substrate 50, a known nonwoven fabric can be used without particular limitation, and for example, a spunbonded nonwoven fabric can be exemplified. The basis weight of the base material 50 is not particularly limited, but from the viewpoint of the strength and operability of the fastening tape 5, it is preferably 30 g/m ² or more, more preferably 40 g/m ² or more, and preferably 100 g/m. ^{It is 2} or less, more preferably 80 g/m ² or less.

延出部５３においては、ベース基材５０の片面、より具体的にはおむつ１の着用時に止着領域６と重ね合わされる被止着面に止着部５１が設置されているとともに、ファスニングテープ５（延出部５３）の折り畳みに使用される折り目５０Ｆが、ベース基材５０を縦方向Ｘに縦断している。本実施形態の折り目５０Ｆは、図４及び図５に示すように、本体重複部５２と延出部５３との境界（すなわち物品本体２の側縁２Ｓ）の近傍、より具体的には両者の境界から横方向Ｙの外方に２．５ｍｍ以内の領域に配されている。折り目５０Ｆは、図２に示すように、ファスニングテープ５を物品本体２側に折り畳むときの折曲線であり、延出部５３の縦方向Ｘの全長にわたって連続している。なお、図２に示す形態では、ファスニングテープ５が折り目５０Ｆにて、物品本体２の肌対向面側（表面シート３１側）に折り畳まれているが、物品本体２の非肌対向面（裏面シート３２側）に折り畳まれてもよい。 In the extending portion 53, the fastening portion 51 is provided on one surface of the base substrate 50, more specifically, on the fastening surface that is overlapped with the fastening region 6 when the diaper 1 is worn, and the fastening tape is provided. The fold line 50F used for folding 5 (extension part 53) vertically cuts the base material 50 in the vertical direction X. As shown in FIG. 4 and FIG. 5, the fold line 50F of the present embodiment is near the boundary between the main body overlapping portion 52 and the extending portion 53 (that is, the side edge 2S of the article main body 2), more specifically, the both. It is arranged outside the boundary in the lateral direction Y in a region within 2.5 mm. As shown in FIG. 2, the fold line 50F is a fold line when the fastening tape 5 is folded toward the article body 2 side, and is continuous over the entire length of the extending portion 53 in the vertical direction X. In the embodiment shown in FIG. 2, the fastening tape 5 is folded at the fold line 50F on the skin-facing surface side (the surface sheet 31 side) of the article body 2, but the non-skin-facing surface of the article body 2 (the back sheet). 32 side) may be folded.

図４及び図５に示すように、延出部５３のベース基材５０における止着部５１の設置面とは反対側の面（以下、「止着部非設置面」ともいう。）には、外層シート５４が接合されている。本実施形態では、延出部５３のみならず本体重複部５２においても、ベース基材５０の止着部非設置面に外層シート５４が接合されている。外層シート５４は、ベース基材５０の止着部非設置面の縦方向Ｘの一端から他端にわたって延在している。 As shown in FIGS. 4 and 5, on the surface of the extension portion 53 on the side opposite to the installation surface of the fastening portion 51 in the base substrate 50 (hereinafter, also referred to as “non-fastening portion non-installation surface”). The outer layer sheet 54 is joined. In the present embodiment, the outer layer sheet 54 is joined to the non-installed portion of the base substrate 50 not only on the extending portion 53 but also on the main body overlapping portion 52. The outer layer sheet 54 extends from one end to the other end in the vertical direction X of the surface on which the fastening portion is not installed of the base substrate 50.

外層シート５４の素材は特に限定されないが、延出部５３に柔軟性を付与するとともに感触を良好なものとし、延出部５３が肌に触れたときに肌を傷付けるおそれを防止する観点から、不織布が好ましい。外層シート５４に用いる不織布としては、公知の不織布を特に制限無く用いることができ、例えば、スパンボンド不織布、スパンボンド−メルトブローン−スパンボンド（ＳＭＳ）不織布、エアスルー不織布を例示できる。外層シート５４の坪量は特に制限されないが、延出部５３の強度や操作性等の観点から、好ましくは１０ｇ／ｍ^２以上、より好ましくは１５ｇ／ｍ^２以上、そして、好ましくは３０ｇ／ｍ^２以下、より好ましくは２５ｇ／ｍ^２以下である。 Although the material of the outer layer sheet 54 is not particularly limited, from the viewpoint of imparting flexibility to the extension portion 53 and making the feel good, and preventing the extension portion 53 from damaging the skin when touching the skin, Nonwoven fabrics are preferred. As the non-woven fabric used for the outer layer sheet 54, known non-woven fabrics can be used without particular limitation, and examples thereof include spunbonded nonwoven fabric, spunbond-meltblown-spunbond (SMS) non-woven fabric, and air-through non-woven fabric. The basis weight of the outer layer sheet 54 is not particularly limited, but is preferably 10 g/m ² or more, more preferably 15 g/m ² or more, and preferably 30 g/m from the viewpoint of the strength and operability of the extending portion 53. ² or less, more preferably 25 g/m ² or less.

ファスニングテープ５における外層シート５４の配置領域には、外層シート５４とベース基材５０との接合部５５が複数存在する。本実施形態では、本体重複部５２及び延出部５３の両方に外層シート５４が配置されており、その両方に接合部５５が存在する。複数の接合部５５は、それぞれ、縦方向Ｘに連続している。少なくとも延出部５３では、縦方向Ｘに連続する複数の接合部５５が、横方向Ｙに間欠配置されている。接合部５５における外層シート５４とベース基材５０との接合手段は特に限定されず、接着剤、ヒートシール、超音波シール等の公知の接合手段を採用することができる。 In the area where the outer layer sheet 54 is arranged in the fastening tape 5, there are a plurality of joints 55 between the outer layer sheet 54 and the base material 50. In the present embodiment, the outer layer sheet 54 is arranged on both the main body overlapping portion 52 and the extending portion 53, and the joint portion 55 is present on both of them. Each of the plurality of joint portions 55 is continuous in the vertical direction X. At least in the extension portion 53, the plurality of joint portions 55 continuous in the vertical direction X are intermittently arranged in the horizontal direction Y. The joining means for joining the outer layer sheet 54 and the base material 50 at the joining portion 55 is not particularly limited, and known joining means such as an adhesive, heat sealing, or ultrasonic sealing can be adopted.

おむつ１の主たる特徴の１つとして、図４及び図５に示すように、外層シート５４とベース基材５０との接合部５５が、ベース基材５０の折り目５０Ｆの横方向Ｙの両側にて縦方向Ｘに連続している点が挙げられる。斯かる構成により、延出部５３の保形性が高められ、前述した、「ファスニングテープの意図しない折れ」の発生が抑制される。 As one of the main characteristics of the diaper 1, as shown in FIG. 4 and FIG. A point that is continuous in the vertical direction X can be mentioned. With such a configuration, the shape retention of the extending portion 53 is enhanced, and the occurrence of the above-mentioned "unintentional bending of the fastening tape" is suppressed.

すなわち仮に、延出部５３に対し、図１２に示す如くに、その縦方向Ｘの両側から外力がかかっても、折り目５０Ｆの横方向Ｙの両側にて縦方向Ｘに連続する接合部５５が、その外力に抵抗するため、延出部５３全体がおしつぶされたように変形することが少なく、したがって、そのような延出部５３の変形に起因する、ファスニングテープ５の操作性の低下やおむつ１の着用感の低下などの不都合の発生が効果的に防止される。また、折り目５０Ｆの横方向Ｙの両側の接合部５５によって延出部５３の保形性が高められているので、例えば、ファスニングテープ５の触感や風合い等の向上の観点から、ベース基材５０や止着部５１の素材として低坪量の不織布のような比較的柔らかく曲がりやすいものを用いても、意図しない折れが生じ難い。したがって、ファスニングテープ５の素材として、風合い等の向上を目的として柔軟なものを用いることで、ファスニングテープ５の風合い等と保形性との両立を図ることが可能となる。 That is, even if external force is applied to the extending portion 53 from both sides in the vertical direction X, as shown in FIG. 12, the joint portions 55 continuous in the vertical direction X are formed on both sides in the horizontal direction Y of the fold line 50F. However, since the extension portion 53 as a whole is resistant to the external force, the extension portion 53 is unlikely to be deformed as if it is squashed. Therefore, the operability of the fastening tape 5 is reduced due to the deformation of the extension portion 53. It is possible to effectively prevent the occurrence of inconveniences such as a decrease in the feeling of wearing the diaper 1. Further, since the shape retention of the extending portion 53 is enhanced by the joint portions 55 on both sides of the fold line 50F in the lateral direction Y, for example, from the viewpoint of improving the feel and texture of the fastening tape 5, the base substrate 50 is improved. Even if a relatively soft and easy-to-bend material such as a low-basis-weight nonwoven fabric is used as the material for the fastening portion 51, unintended breakage is unlikely to occur. Therefore, by using a flexible material as the material of the fastening tape 5 for the purpose of improving the texture, it is possible to achieve both the texture of the fastening tape 5 and the shape retention.

本実施形態では、ファスニングテープ５を展開した状態（以下、「ファスニングテープ５の展開状態」ともいう。）において、すなわちファスニングテープ５を折り目５０Ｆで折り畳まれた状態から展開状態にした場合において、図５及び図６に示すように、折り目５０Ｆの横方向Ｙの両側に位置して折り目５０Ｆに最も近接する一対の接合部５５，５５に挟まれた部分にて、ベース基材５０が外層シート５４から離れる方向に湾曲しているか、又は外層シート５４がベース基材５０から離れる方向に湾曲している。そしてこれにより、ファスニングテープ５の延出部５３における折り目５０Ｆの形成位置に、ベース基材５０及び外層シート５４の少なくとも一方が他方から離れる方向に湾曲してなる柱状部５６が、縦方向Ｘに延在している。ファスニングテープ５の展開状態は、具体的には例えば、ファスニングテープ５の止着部５１を止着領域６に係合させた状態、すなわちおむつ１の着用状態である。このように、ファスニングテープ５の展開状態において、延出部５３にその構成部材が湾曲してなる柱状部５６が縦方向Ｘに延在していることにより、延出部５３の保形性が向上し、前述した、接合部５５による延出部５３の保形性の向上効果と相俟って、延出部５３の保形性がより一層向上し、「ファスニングテープの意図しない折れ」の発生がより一層確実に抑制され得る。 In the present embodiment, the state in which the fastening tape 5 is unfolded (hereinafter, also referred to as the "unfolded state of the fastening tape 5"), that is, when the fastening tape 5 is unfolded from the state folded at the fold line 50F, As shown in FIGS. 5 and 6, the base material 50 is located on both sides of the fold line 50F in the lateral direction Y and sandwiched by the pair of joint portions 55, 55 closest to the fold line 50F. The outer layer sheet 54 is curved in a direction away from the base substrate 50. As a result, at the position where the fold line 50F is formed in the extending portion 53 of the fastening tape 5, the columnar portion 56 formed by bending at least one of the base material 50 and the outer layer sheet 54 in the direction away from the other is formed in the longitudinal direction X. It has been extended. Specifically, the deployed state of the fastening tape 5 is, for example, a state in which the fastening portion 51 of the fastening tape 5 is engaged with the fastening region 6, that is, the wearing state of the diaper 1. In this manner, when the fastening tape 5 is in the unfolded state, the columnar portion 56 formed by bending the constituent members in the extending portion 53 extends in the vertical direction X, so that the shape retaining property of the extending portion 53 is maintained. Combined with the above-described effect of improving the shape retention of the extension portion 53 by the joint portion 55, the shape retention of the extension portion 53 is further improved, and “unintentional bending of the fastening tape” Occurrence can be suppressed more reliably.

なお、柱状部５６が形成されるのは、通常、ファスニングテープ５の展開状態であり、例えば、図２の左側のファスニングテープ５のように、ファスニングテープ５を折り目５０Ｆで折り畳んだ状態（延出部５３を物品本体２に重ねた状態）では、柱状部５６は形成されない。また、図面に記載された柱状部５６の形状は、あくまで模式的なものであって、実際の柱状部５６の形状が図示の如き形状になるとは限らない。 The columnar portion 56 is usually formed in the unfolded state of the fastening tape 5. For example, as in the left fastening tape 5 in FIG. 2, the fastening tape 5 is folded at the fold line 50F (extension). The columnar portion 56 is not formed in the state where the portion 53 is superposed on the article body 2. Further, the shape of the columnar portion 56 shown in the drawings is merely a schematic one, and the actual shape of the columnar portion 56 is not always the shape as shown.

本実施形態では、展開状態のファスニングテープ５の延出部５３において、折り目５０Ｆの形成位置のみならず、折り目５０Ｆが形成されていない部分にも柱状部５６が形成されている。すなわち本実施形態では、ファスニングテープ５の展開状態（おむつ１の着用状態）において、図５に示すように、延出部５３における折り目５０Ｆよりも横方向Ｙの外方に、縦方向Ｘに連続する接合部５５が横方向Ｙに複数間欠配置され、その複数の接合部５５において横方向Ｙに隣り合う接合部５５どうしの間にて、ベース基材５０が外層シート５４から離れる方向に湾曲しているか、又は外層シート５４がベース基材５０から離れる方向に湾曲しており、斯かる外層シート５４及び／又はベース基材５０の湾曲により、折り目５０Ｆの形成位置の柱状部５６よりも横方向Ｙの外方に中空の柱状部５６が複数形成されている。つまり、本実施形態の延出部５３では、ファスニングテープ５の展開状態において、折り目５０Ｆよりも横方向Ｙの外方に、接合部５５と柱状部５６とが横方向Ｙに交互に配置されている。このように、延出部５３に柱状部５６が横方向Ｙに複数間欠配置されていることにより、折り目５０Ｆの形成位置のみに柱状部５６が形成されている場合に比して、延出部５３の保形性がより一層高められ、前述した効果がより一層確実に奏され得る。なお、図５に示す形態では、本体重複部５２にも柱状部５６が形成されているが、本体重複部５２は物品本体２に固定される部分であり、その固定形態の如何によっては、本体重複部５２に柱状部５６が形成されるとは限らない。 In the present embodiment, in the extending portion 53 of the fastening tape 5 in the unfolded state, the columnar portion 56 is formed not only at the position where the fold line 50F is formed but also at the portion where the fold line 50F is not formed. That is, in the present embodiment, in the unfolded state of the fastening tape 5 (wearing state of the diaper 1), as shown in FIG. 5, the extended portion 53 is continuous in the longitudinal direction X outward in the lateral direction Y with respect to the fold line 50F. A plurality of joining portions 55 are intermittently arranged in the lateral direction Y, and the base material 50 is curved in a direction away from the outer layer sheet 54 between the joining portions 55 adjacent to each other in the lateral direction Y in the plurality of joining portions 55. Or the outer layer sheet 54 is curved in a direction away from the base material 50, and due to the bending of the outer layer sheet 54 and/or the base material 50, the outer layer sheet 54 and/or the base material 50 are lateral to the columnar portion 56 at the formation position of the fold line 50F. A plurality of hollow columnar portions 56 are formed outside Y. That is, in the extending portion 53 of the present embodiment, in the expanded state of the fastening tape 5, the joining portions 55 and the columnar portions 56 are alternately arranged in the lateral direction Y outside the fold line 50F. There is. In this way, the plurality of columnar portions 56 are intermittently arranged in the lateral direction Y in the extending portion 53, so that the extending portion is formed as compared with the case where the columnar portion 56 is formed only at the formation position of the fold line 50F. The shape retention property of 53 is further enhanced, and the above-described effects can be more reliably exhibited. In addition, in the form shown in FIG. 5, the columnar part 56 is also formed in the main body overlapping part 52, but the main body overlapping part 52 is a part fixed to the article main body 2, and the main body depending on the fixing form. The columnar portion 56 is not always formed in the overlapping portion 52.

本実施形態の延出部５３では、ファスニングテープ５の展開状態において、折り目５０Ｆの形成位置及びそれ以外の他の部分の両方に柱状部５６が形成されているが、特に柱状部５６が形成されやすいのは、折り目５０Ｆの形成位置である。その理由は、ベース基材５０における折り目５０Ｆの形成位置（折り目５０Ｆ及びその近傍）は、図６に示すように、本来的にベース基材５０が折り目５０Ｆを頂部として、延出部５３の厚み方向（図６の上下方向）の外方に凸状に屈曲ないし湾曲しやすいためである。また、外層シート５４は、接合部５５にてベース基材５０に接合されているため、接合部５５の形成位置ではベース基材５０側に凹状に窪み、横方向Ｙに隣り合う接合部５５どうしの間ではベース基材５０から離れる方向に湾曲しやすい。このように、折り目５０Ｆの形成位置では、ベース基材５０及び外層シート５４の双方が互いに離れる方向に湾曲しやすく、そのため、折り目５０Ｆの形成位置に柱状部５６が形成されやすい。また、折り目５０Ｆの形成位置に存在する柱状部５６は、ベース基材５０及び外層シート５４の双方の湾曲程度が比較的大きく、図６に示す如き断面視（柱状部５６の延在方向すなわち縦方向Ｘと直交する方向の断面視）において円形に近い中空の形状をなしており、そのため、縦方向Ｘの両側からの外力に対する抵抗力が強力である。 In the extending portion 53 of the present embodiment, the columnar portions 56 are formed at both the formation position of the fold line 50F and other portions other than that in the unfolded state of the fastening tape 5, but the columnar portion 56 is particularly formed. It is easy to find the position where the fold line 50F is formed. The reason is that at the formation position of the fold line 50F (the fold line 50F and its vicinity) in the base substrate 50, as shown in FIG. 6, the base substrate 50 originally has the fold line 50F as the top portion and the thickness of the extending portion 53. This is because it tends to bend or curve outward in the direction (vertical direction in FIG. 6). Further, since the outer layer sheet 54 is bonded to the base material 50 at the bonding portions 55, the outer layer sheet 54 is concavely recessed toward the base material 50 at the position where the bonding portions 55 are formed, and the bonding portions 55 adjacent to each other in the lateral direction Y are joined together. Between them, it is easy to bend in the direction away from the base material 50. As described above, at the formation position of the fold line 50F, both the base material 50 and the outer layer sheet 54 are likely to bend in a direction away from each other, and thus the columnar portion 56 is easily formed at the formation position of the fold line 50F. Further, the columnar portion 56 existing at the position where the fold line 50F is formed has a relatively large degree of curvature of both the base material 50 and the outer layer sheet 54, and thus has a cross-sectional view as shown in FIG. It has a hollow shape close to a circle in a cross-sectional view in the direction orthogonal to the direction X), and therefore has a strong resistance to external force from both sides in the vertical direction X.

一方、延出部５３における折り目５０Ｆの形成位置以外の他の部分については、折り目５０Ｆが存在しないため、折り目５０Ｆの形成位置との比較においては、図７に示すように、ベース基材５０及び外層シート５４の少なくとも一方が他方から離れる方向に湾曲し難く、したがってファスニングテープ５の展開状態において、柱状部５６が形成され難く、また、形成されてもその柱状部５６は、折り目５０Ｆの形成位置における柱状部５６に比して、ベース基材５０及び／又は外層シート５４の湾曲の程度が小さく、縦方向Ｘの両側からの外力に対する抵抗力に劣る。しかしながら、これはあくまで折り目５０Ｆの形成位置に存在する柱状部５６と比較した場合のことであり、典型的にはファスニングテープ５の展開状態において、延出部５３における折り目５０Ｆの形成位置以外の他の部分にも柱状部５６が形成され、また、該他の部分に存在する柱状部５６は、延出部５３の保形性の向上に十分に寄与し得る。 On the other hand, since the folds 50F do not exist in portions other than the formation positions of the folds 50F in the extension portion 53, as compared with the formation positions of the folds 50F, as shown in FIG. At least one of the outer layer sheets 54 is unlikely to bend in a direction away from the other, so that the columnar portion 56 is difficult to be formed in the expanded state of the fastening tape 5, and even if it is formed, the columnar portion 56 is formed at the position where the fold line 50F is formed. The degree of bending of the base material 50 and/or the outer layer sheet 54 is smaller than that of the columnar portion 56 in, and the resistance to external force from both sides in the vertical direction X is poor. However, this is only when compared with the columnar portion 56 existing at the formation position of the fold line 50F, and typically in the unfolded state of the fastening tape 5, other than the formation position of the fold line 50F in the extension part 53. The columnar portion 56 is also formed in this portion, and the columnar portion 56 existing in the other portion can sufficiently contribute to improving the shape retention of the extending portion 53.

図８には、図２のＩＩ−ＩＩ線断面の一実施形態が示されている。図８に示す形態では、ファスニングテープ５の展開状態において、延出部５３における折り目５０Ｆの形成位置におけるベース基材５０と外層シート５４との間に空間Ｓが形成されている。より具体的には、図８に示す形態では、ベース基材５０及び外層シート５４それぞれにおける折り目５０Ｆに位置する部分が周辺部よりも厚み方向の外方に突出し、且つその両突出部どうしは互いに同方向（止着部非設置面側）に突出している。また、外層シート５４の突出部の方が、ベース基材５０の突出部よりも歪曲程度が大きく、そのため、前者が後者に比して、突出高さ及び／又は横方向Ｙの長さ（突出幅）が大きい。このような、折り目５０Ｆの形成位置におけるベース基材５０と外層シート５４との歪曲程度の違いに起因して、ファスニングテープ５の展開状態において、両者間に空間Ｓが形成される。 FIG. 8 shows an embodiment of a cross section taken along the line II-II of FIG. In the form shown in FIG. 8, in the unfolded state of the fastening tape 5, a space S is formed between the base material 50 and the outer layer sheet 54 at the position where the fold line 50F is formed in the extension portion 53. More specifically, in the form shown in FIG. 8, the portions of the base 50 and the outer layer sheet 54 located at the folds 50F project outward in the thickness direction rather than the peripheral portion, and both projecting portions are mutually It projects in the same direction (on the side where the fastening part is not installed). Further, the protrusion of the outer layer sheet 54 has a larger degree of distortion than the protrusion of the base material 50, and therefore the former is higher in protrusion height and/or the length in the lateral direction Y (protrusion) than the latter. The width is large. Due to such a difference in the degree of distortion between the base material 50 and the outer layer sheet 54 at the position where the fold line 50F is formed, a space S is formed between the two in the developed state of the fastening tape 5.

前述した柱状部５６による作用効果をより一層確実に奏させるようにする観点から、接合部５５は、延出部５３の縦方向Ｘの全長にわたって連続していることが好ましい。これにより、柱状部５６が延出部５３の縦方向Ｘの全長にわたって安定的に形成され、柱状部５６による作用効果をより一層確実に奏され得る。尤も、接合部５５は、必ずしも延出部５３の縦方向Ｘの一端から他端の全体にわたって連続する必要はなく、延出部５３の縦方向Ｘの全長の好ましくは５０％以上、より好ましくは７５％以上にわたって連続していればよい。また、接合部５５が縦方向Ｘに連続する部分は、少なくとも延出部５３の縦方向Ｘの両端部を除く部分に存在することが好ましい。 From the viewpoint of more reliably producing the above-described function and effect of the columnar portion 56, the joining portion 55 is preferably continuous over the entire length of the extending portion 53 in the vertical direction X. Accordingly, the columnar portion 56 is stably formed over the entire length of the extending portion 53 in the vertical direction X, and the function and effect of the columnar portion 56 can be more reliably exhibited. However, the joint portion 55 does not necessarily have to be continuous from one end to the other end of the extension portion 53 in the vertical direction X, and is preferably 50% or more of the total length of the extension portion 53 in the vertical direction X, and more preferably. It may be continuous for 75% or more. Further, it is preferable that the portion where the joint portion 55 is continuous in the vertical direction X is present at least in a portion excluding both ends of the extending portion 53 in the vertical direction X.

同様の観点から、横方向Ｙに隣り合う接合部５５どうしの間隔は、好ましくは１ｍｍ以上、より好ましくは２ｍｍ以上、そして、好ましくは５ｍｍ以下、より好ましくは４ｍｍ以下である。斯かる間隔は、柱状部５６の横方向Ｙに沿う長さと実質的に同じである。 From the same viewpoint, the interval between the joint portions 55 adjacent to each other in the lateral direction Y is preferably 1 mm or more, more preferably 2 mm or more, and preferably 5 mm or less, more preferably 4 mm or less. Such an interval is substantially the same as the length of the columnar portion 56 along the lateral direction Y.

延出部５３に柱状部５６を安定的に形成する観点から、図２の右側のファスニングテープ５のように、延出部５３を物品本体２に重ねずに物品本体２から延出させた状態において、延出部５３は、図９に示すように、止着部５１の設置面側に凸に反っていることが好ましい。このように延出部５３を片面側に反らせる方法としては、ベース基材５０及び／又は止着部５１として、本来的に片面側に反っているものを使用する方法が挙げられる。そのような本来的に片面側に反ったベース基材５０や止着部５１は、例えば、ベース基材５０や止着部５１の長尺帯状物をロール状に巻回して癖付けしておくことで得られる。また、延出部５３を片面側に反らせる他の方法として、外層シート５４を横方向Ｙに伸長させた状態でベース基材５０に接合する方法が挙げられる。横方向Ｙに伸長状態の外層シート５４をベース基材５０に接合した後、その伸長状態を解除することで、延出部５３を、外層シート５４側とは反対側すなわち止着部５１の設置面側に凸に反らせ得る。 From the viewpoint of stably forming the columnar portion 56 in the extending portion 53, a state in which the extending portion 53 is extended from the article body 2 without overlapping the article body 2 like the fastening tape 5 on the right side of FIG. In FIG. 9, it is preferable that the extending portion 53 is convexly warped toward the installation surface side of the fastening portion 51, as shown in FIG. 9. As a method of bending the extending portion 53 to the one surface side in this way, a method of using the base substrate 50 and/or the fastening portion 51 that is originally curved to the one surface side is used. The base material 50 and the fastening portion 51 that originally warp on one side are, for example, formed by winding a long strip of the base material 50 and the fastening portion 51 in a roll shape. It can be obtained. Further, as another method of bending the extending portion 53 to the one side, there is a method of joining the outer layer sheet 54 to the base material 50 in a state of being extended in the lateral direction Y. After the outer layer sheet 54 stretched in the lateral direction Y is joined to the base 50, the stretched state is released, so that the extending portion 53 is provided on the side opposite to the outer layer sheet 54 side, that is, the fastening portion 51 is installed. The surface can be convexly curved.

止着部５１は、ベース基材５０に対して接着剤を介さずに接合されていることが好ましい。止着部５１がホットメルト型接着剤の如き接着剤によってベース基材５０に接合されていると、その接合部（接着剤の塗布部）が比較的硬いために、ベース基材５０ないし外層シート５４の湾曲が阻害されるおそれがあり、柱状部５６の形成に支障をきたすおそれがある。止着部５１をベース基材５０に対して接着剤を介さずに接合することで、その接合部分の柔軟性が維持されやすく、柱状部５６の形成が促進されやすい。接着剤以外の止着部５１のベース基材５０への接合手段としては、融着を例示できる。斯かる融着は、例えば、ベース基材５０及び止着部５１の何れか一方又は両方の形成材料を溶融させた状態で両者を接触させ、冷却、固化することでなし得る。 The fastening portion 51 is preferably joined to the base material 50 without an adhesive. When the fastening portion 51 is joined to the base substrate 50 with an adhesive such as a hot melt adhesive, the joint portion (adhesive application portion) is relatively hard, and thus the base substrate 50 or the outer layer sheet. The curve of 54 may be hindered, and the formation of the columnar portion 56 may be hindered. By joining the fastening portion 51 to the base material 50 without using an adhesive, the flexibility of the joining portion is easily maintained and the formation of the columnar portion 56 is easily promoted. As a means for joining the fastening portion 51 to the base material 50 other than the adhesive, fusion can be exemplified. Such fusing can be performed by, for example, bringing one or both of the base material 50 and the fastening portion 51 into a molten state and bringing them into contact with each other, and then cooling and solidifying.

図１０に示すように、延出部５３における外層シート５４側の面には、外層シート５４、ベース基材５０及び止着部５１が該止着部５１の設置面側に一体的に凹陥してなる凹陥部５７が形成されていることが好ましい。これにより、延出部５３が図１０に示すように止着部５１の設置面側に凸に反りやすくなるため、柱状部５６がより一層安定的に形成されやすくなる。凹陥部５７は、例えば、熱を伴うか又は伴わないエンボス加工、超音波エンボス加工によって形成することができる。凹陥部５７の平面視形状は特に限定されず、例えば、円形状、楕円形状、矩形状であり得る。 As shown in FIG. 10, the outer layer sheet 54, the base material 50, and the fastening portion 51 are integrally recessed on the surface of the extending portion 53 on the outer layer sheet 54 side on the installation surface side of the fastening portion 51. It is preferable that the concave portion 57 formed by the above is formed. As a result, the extending portion 53 is likely to warp convexly toward the installation surface side of the fastening portion 51 as shown in FIG. 10, so that the columnar portion 56 is likely to be formed more stably. The recess 57 can be formed by, for example, embossing with or without heat or ultrasonic embossing. The plan view shape of the recess 57 is not particularly limited, and may be, for example, a circular shape, an elliptical shape, or a rectangular shape.

また、凹陥部５７は図１０に示すように、接合部５５に形成されていることが好ましい。ベース基材５０及び／又は外層シート５４の湾曲の起点となる接合部５５に凹陥部５７が存在することで、延出部５３が止着部５１の設置面側に凸に反りやすくなるため、柱状部５６が一層安定的に形成されやすくなる。接合部５５に重ねて凹陥部５７を形成する場合、凹陥部５７は、縦方向Ｘに連続する接合部５５の任意の位置に任意の数形成することができる。例えば、接合部５５の縦方向Ｘの中央部に凹陥部５７を１個形成してもよく、あるいは、接合部５５に凹陥部５７を縦方向Ｘに複数間欠配置してもよい。 Further, the recess 57 is preferably formed in the joint 55 as shown in FIG. The presence of the concave portion 57 in the joint portion 55, which is the starting point of the curvature of the base material 50 and/or the outer layer sheet 54, makes the extended portion 53 more likely to warp convexly toward the installation surface side of the fastening portion 51. The columnar portion 56 is likely to be formed more stably. When the recessed portion 57 is formed so as to overlap the joint portion 55, the recessed portion 57 can be formed in any number at any position of the joint portion 55 continuous in the vertical direction X. For example, one concave portion 57 may be formed in the central portion of the joint portion 55 in the vertical direction X, or a plurality of concave portions 57 may be intermittently arranged in the joint portion 55 in the vertical direction X.

接合部５５は、接着剤以外の接合手段、例えば、ヒートシールや超音波シール等によって形成されてもよいが、接合部５５においては、外層シート５４とベース基材５０とが接着剤によって接合されていることが好ましい。これにより、接合部５５のパターン（平面視形状及び配置）の調整が一層容易になる。例えば、接合部５５がホットメルト型接着剤から構成され、そのホットメルト型接着剤の塗布部である接合部５５が、図４及び図５に示す如くに横方向Ｙに複数間欠配置されたパターンが好ましい。 The joining portion 55 may be formed by joining means other than an adhesive, for example, heat sealing, ultrasonic sealing, or the like. In the joining portion 55, the outer layer sheet 54 and the base substrate 50 are joined by an adhesive. Preferably. This makes it easier to adjust the pattern (shape and arrangement in plan view) of the joint portion 55. For example, the joint portion 55 is made of a hot-melt adhesive, and a plurality of joint portions 55, which are the application portions of the hot-melt adhesive, are intermittently arranged in the lateral direction Y as shown in FIGS. 4 and 5. Is preferred.

延出部５３を、該延出部５３を縦方向Ｘに二等分する折曲線（図示せず）で縦方向Ｘに二つ折りした場合において、該延出部５３の一方の面側（止着部５１の設置面側）に折り曲げたときの曲げ剛性Ｇ１と、他方の面側（止着部非設置面側）に折り曲げたときの曲げ剛性Ｇ２とで、差が小さいことが好ましく、両者の比率が、曲げ剛性Ｇ１／曲げ剛性Ｇ２として１に近いことが好ましい。斯かる構成により、延出部５３が一方の面側に集中的に折れ曲がることが抑制され、延出部５３の保形性がより一層向上し得る。曲げ剛性Ｇ１と曲げ剛性Ｇ２との比率は、曲げ剛性Ｇ１／曲げ剛性Ｇ２として、好ましくは０．６以上１．５以下、より好ましくは０．８以上１．２以下である。曲げ剛性は、以下のようにして測定することができる。 When the extending portion 53 is folded in two in the vertical direction X along a folding curve (not shown) that bisects the extending portion 53 in the vertical direction X, one surface side of the extending portion 53 (stop It is preferable that the difference between the bending rigidity G1 when bent to the installation surface side of the attachment part 51 and the bending rigidity G2 when bent to the other surface side (the installation part non-installation surface side) is small. It is preferable that the ratio of B is close to 1 as bending rigidity G1/bending rigidity G2. With such a configuration, it is possible to prevent the extending portion 53 from being bent to one surface side intensively, and to further improve the shape retention of the extending portion 53. The ratio of bending rigidity G1 and bending rigidity G2 is preferably 0.6 or more and 1.5 or less, more preferably 0.8 or more and 1.2 or less, as bending rigidity G1/bending rigidity G2. Bending rigidity can be measured as follows.

＜曲げ剛性の測定方法＞
ファスニングテープの曲げ剛性は、カトーテック株式会社製のＫＥＳ曲げ測定機（ＫＥＳ−ＦＢ２）を用いて、ＫＥＳ法によって測定する。曲げ剛性値として、試験片の単位長さあたりの曲げモーメントＭと曲率ＫとのＭ−Ｋ曲線の傾斜である、単位長さあたりの曲げ剛性Ｂを測定する。ＫＥＳ法に関しては、「風合い評価の標準化と解析」第２版（社団法人日本繊維機械学会風合い計量と規格化研究委員会昭和５５年７月１０日発行）に詳細が説明されている。力学的性質毎の測定方法に関し、本測定に関連した測定条件は次のとおりである。ＫＥＳ曲げ測定機のチャック間距離を１０ｍｍとして、該チャック間に試験片を固定する。試験片として、ファスニングテープ５の延出部５３を含む部分を用いる。試験片をチャック間に固定する際には、該試験片が、該試験片（延出部５３）を縦方向Ｘに二等分する折曲線で縦方向Ｘに二つ折りされるように、チャック間に非曲げ状態で固定する。また、重力の影響を少なくするために、チャック間において試験片は垂直に固定する。チャック間に非曲げ状態で固定された試験片を、先ず、該試験片の一方の面側に最大曲率＋２．５ｃｍ−１まで曲げ、次に、該試験片の他方の面側に最大曲率−２．５ｃｍ−１まで曲げた後、試験片を元の非曲げ状態に戻し、斯かる一連の曲げ操作における曲げ剛性Ｂを測定する。各曲げ方向における測定値の曲率＋０．５ｃｍ−１から＋１．５ｃｍ−１間の曲げ剛性Ｂの値をＧ１とし、曲率−０．５ｃｍ−１から―１．５ｃｍ−１間の曲げ剛性Ｂの値をＧ２とする。 <Bending rigidity measurement method>
The bending rigidity of the fastening tape is measured by the KES method using a KES bend measuring machine (KES-FB2) manufactured by Kato Tech Co., Ltd. As the bending rigidity value, the bending rigidity B per unit length, which is the slope of the M-K curve of the bending moment M and the curvature K per unit length of the test piece, is measured. The KES method is described in detail in "Standardization and analysis of texture evaluation", second edition (Japan Textile Machinery Society, Texture Measurement and Standardization Research Committee, published on July 10, 1980). Regarding the measurement method for each mechanical property, the measurement conditions related to this measurement are as follows. The distance between the chucks of the KES bending measuring machine is set to 10 mm, and the test piece is fixed between the chucks. As the test piece, a portion including the extending portion 53 of the fastening tape 5 is used. When fixing the test piece between the chucks, the chuck is so arranged that the test piece is folded in two in the vertical direction X along a folding curve that bisects the test piece (extension portion 53) in the vertical direction X. Secure in a non-bent state. Also, in order to reduce the influence of gravity, the test piece is fixed vertically between the chucks. The test piece fixed between the chucks in a non-bent state was first bent on one surface side of the test piece to a maximum curvature of +2.5 cm-1, and then on the other surface side of the test piece. After bending to 2.5 cm-1, the test piece is returned to the original non-bent state, and the bending rigidity B in such a series of bending operations is measured. Let G1 be the value of the bending stiffness B between the curvature of +0.5 cm-1 and +1.5 cm-1 in each bending direction, and let the bending stiffness B of the curvature between -0.5 cm-1 and -1.5 cm-1 be B1. The value is G2.
