Description

複合シート材とその製造方法及びこれを用いた使い捨て着用物品COMPOSITE SHEET MATERIAL, ITS MANUFACTURING METHOD, AND DISPOSABLE WEARING ARTICLE USING THE SAME
　本発明は、使い捨ておむつなどの使い捨て着用物品の表面シート等に用いられる複合シート材とその製造方法及びこれを用いた使い捨て着用物品に関し、さらに詳しくは、優れたフィット性を備えながら、着用時の感触を良好にするとともに、着用者の肌との間の通気性を良好に確保して蒸れの発生を効果的に防止できる、複合シート材とその製造方法及びこれを用いた使い捨て着用物品に関する。 The present invention relates to a composite sheet material used for a surface sheet or the like of a disposable wearing article such as a disposable diaper, a manufacturing method thereof, and a disposable wearing article using the same, and more specifically, while having excellent fit, The present invention relates to a composite sheet material, a method for producing the same, and a disposable wearing article using the composite sheet material, which can make the feel good and ensure air permeability between the skin of the wearer and effectively prevent the occurrence of stuffiness.
　従来、使い捨ておむつなどの使い捨て着用物品には、ゴム糸などの弾性部材を備えた複合シート材を腰部等に用いることで着用時のフィット性を高めたものがある。例えば、２枚のシート材間に上記の弾性部材を配置して複合シート材を形成し、その弾性部材が収縮することで、その複合シート材の表面に多数の襞を形成して、感触を柔らかくすることが提案されている(例えば、特許文献１参照、以下、従来技術という。)。 Conventionally, some disposable wearing articles such as disposable diapers have improved fit at the time of wearing by using a composite sheet material provided with an elastic member such as a rubber thread for a waist or the like. For example, the elastic member is arranged between two sheet materials to form a composite sheet material, and the elastic member contracts to form a large number of wrinkles on the surface of the composite sheet material. It has been proposed to soften (see, for example, Patent Document 1, hereinafter referred to as the prior art).
　上記の従来技術は、上記の弾性部材の伸縮方向とそれに直交する方向との両方向において、それぞれ間欠的に、上記の２枚のシート材を互いに接合してある。これにより、その接合していない部分のシート材が、弾性体の収縮により変形して襞となる。そして上記の弾性部材の中間部分は、上記のシート同士の接合部分以外を通過しており、シート材とは接合しないことで、複合シート材の柔軟性を高めてある。 In the above-described prior art, the two sheet materials are joined to each other intermittently in both directions of the elastic member expansion and contraction and the direction orthogonal thereto. Thereby, the sheet | seat material of the part which has not joined is deform | transformed by shrinkage | contraction of an elastic body, and becomes a wrinkle. And the intermediate part of said elastic member has passed through other than the junction part of said sheet | seat, and has improved the softness | flexibility of the composite sheet material by not joining with a sheet material.
特開２００５－０８０８５９号公報Japanese Patent Laid-Open No. 2005-080859
　しかしながら上記の従来技術は、弾性部材の収縮により上記の襞が形成されるため、着用時に弾性部材が伸びた状態になると、その伸びた部分では上記の襞が消失することとなる。また上記の従来技術では、弾性部材の収縮によりシート材が変形して上記の襞が形成されるが、上記の弾性体は両端でのみ上記のシート材に固定されているため、弾性体に対しシート材がずれ動き易く、このずれ動きによりシート材の変形に偏りが生じると、その変形が少なくなった部分で襞が消失する虞がある。また上記の襞は弾性体の収縮方向へ倒れるように変形しやすく、弾性体が収縮した場合などに襞と襞とが互いに折重なった状態となる虞もある。
　これらの結果、この複合シート材を用いた使い捨て着用物品は、柔らかさや肌触りなどの着用時の感触が低下したり、襞と襞の間の通気性が阻害されて蒸れ易くなったりする等の問題がある。 However, since the above-described conventional technology forms the above-described folds by contraction of the elastic member, the above-described folds disappear at the extended portion when the elastic member is stretched during wearing. Further, in the above prior art, the sheet material is deformed by the contraction of the elastic member, and the above-described ridge is formed. However, since the elastic body is fixed to the sheet material only at both ends, If the sheet material is easily displaced, and the deformation of the sheet material is biased due to this displacement, wrinkles may disappear at a portion where the deformation is reduced. Further, the above-described folds are easily deformed so as to fall in the contraction direction of the elastic body, and there is a possibility that the heel and the heel are folded over when the elastic body contracts.
As a result, the disposable wearing article using this composite sheet material has problems such as a soft feeling and a feeling when worn, such as a touch, and a tendency to get stuffy because the air permeability between the heel and the heel is hindered. There is.
　本発明の技術的課題は上記の問題点を解消し、優れたフィット性を備えながら、着用時の感触を良好にするとともに、着用者の肌との間の通気性を良好に確保して蒸れの発生を効果的に防止できる、複合シート材とその製造方法及びこれを用いた使い捨て着用物品を提供することにある。 The technical problem of the present invention is to eliminate the above-mentioned problems and to provide a good fit while ensuring a good feel when worn, and to ensure good breathability between the wearer's skin and stuffiness. It is providing the composite sheet material which can prevent generation | occurrence | production effectively, its manufacturing method, and the disposable wearing article using the same.
　本発明は上記の課題を解決するために、次のように構成したものである。
　即ち本発明１は複合シート材に関し、互いに接合された２枚のシート材と、これら両シート材間に配置された長尺の弾性部材とを備える複合シート材であって、上記の２枚のシート材のうち少なくとも一方のシート材には、他方のシート材側とは反対側に突出している複数の凸部が上記の接合に先立って予め形成してあり、この凸部の周囲で上記の２枚のシート材が互いに接合してあることを特徴とする。 In order to solve the above-mentioned problems, the present invention is configured as follows.
That is, the present invention 1 relates to a composite sheet material, which is a composite sheet material comprising two sheet materials joined to each other and a long elastic member disposed between the two sheet materials, At least one of the sheet materials has a plurality of protrusions protruding in advance on the side opposite to the other sheet material side prior to the above-mentioned joining, Two sheet materials are bonded to each other.
　また、本発明２は複合シート材の製造方法に関し、互いに平行に配置された、対面位置で互いに噛み合う凹凸形状をロール周面にそれぞれ備える一対の賦形ロール間に第１シート材を通過させて、この第１シート材に所定形状の第１凸部を形成したのち、この第１シート材の第１凸部を突出させた側とは反対側の表面に第２シート材を、弾性部材を挟み込みながら重ね合せ、上記の第１凸部の周囲で両シート材を互いに接合することを特徴とする。 Moreover, this invention 2 is related with the manufacturing method of a composite sheet material, and makes a 1st sheet material pass between a pair of shaping rolls which are arrange | positioned in parallel mutually and which each have the uneven | corrugated shape which mutually meshes | engages in a facing position on a roll peripheral surface. After forming the first convex portion having a predetermined shape on the first sheet material, the second sheet material is placed on the surface of the first sheet material opposite to the side from which the first convex portion is projected, and the elastic member is attached. The sheet materials are overlapped while being sandwiched, and both the sheet materials are joined to each other around the first convex portion.
　また本発明３は使い捨て着用物品に関し、上記の本発明１の複合シート材を備えることを特徴とする。 Further, the present invention 3 relates to a disposable wearing article, and is characterized by comprising the composite sheet material of the present invention 1 described above.
　本発明１の複合シート材は、少なくとも一方のシート材に複数の凸部が予め形成してあり、この凸部の周囲で２枚のシート材が互いに接合してあるので、上記の弾性部材の伸縮にかかわらずこのシート材に上記の凸部が維持されている。このため、上記の弾性部材が伸長してこのシート材が引き伸ばされても、上記の凸部は容易に消失することがなく、また弾性部材の収縮時などに、上記の凸部が倒れるように変形したり折れ重なったりすることが防止される。 In the composite sheet material of the present invention 1, a plurality of convex portions are formed in advance on at least one sheet material, and two sheet materials are joined to each other around the convex portions. Regardless of expansion and contraction, the above-mentioned convex portions are maintained on this sheet material. For this reason, even if the elastic member is stretched and the sheet material is stretched, the convex portion is not easily lost, and the convex portion is collapsed when the elastic member is contracted. It is prevented from being deformed or folded.
　上記の弾性部材としては、使い捨て着用物品に用いられる各種公知の弾性部材を任意に選択して用いることができ、例えば合成ゴムや天然ゴムのほか、ゴム弾性を備えた合成樹脂などからなる、糸条体やテープ状のもの等が好ましく使用される。
　上記の弾性部材は、上記の両シート材間の任意の位置に配置できるが、両シート材が互いに接合されている箇所に挟持されてこれらのシート材に固定してあると、この弾性部材が伸縮してもこの弾性部材に対しシート材が大きくずれ動くことがなく、シート材を均一に伸縮できるので好ましい。 As the above-mentioned elastic member, various known elastic members used for disposable wearing articles can be arbitrarily selected and used. For example, in addition to synthetic rubber and natural rubber, a thread made of synthetic resin having rubber elasticity A strip or tape-like material is preferably used.
The elastic member can be disposed at any position between the two sheet materials. However, when the two sheet materials are sandwiched and fixed to these sheet materials, Even if the sheet is expanded or contracted, the sheet material does not move greatly with respect to the elastic member, and the sheet material can be expanded and contracted uniformly, which is preferable.
　上記のシート材としては、例えばエアースルー不織布、ヒートロール不織布、スパンレース不織布、スパンボンド不織布、メルトブローン不織布等の各種製法による不織布のほか、織布、編布、樹脂フィルム等を任意に採用することができ、さらにはこれらを２種以上組み合わせて積層したものを用いてもよい。また上記の２枚のシート材は、互いに同一種類のシート材であってもよく、互いに異なる種類のシート材であってもよい。このシート材を形成する材料は、特定のものに限定されないが、接着剤等を用いずに熱融着により互いに接合すると複合シート材を柔らかくできることから、例えば、ポリオレフィン樹脂など、熱融着が可能な樹脂を含んでいると好ましい。 As the sheet material, for example, woven fabrics, knitted fabrics, resin films, etc., as well as non-woven fabrics by various production methods such as air-through nonwoven fabric, heat roll nonwoven fabric, spunlace nonwoven fabric, spunbond nonwoven fabric, and melt blown nonwoven fabric may be arbitrarily employed. In addition, a laminate obtained by combining two or more of these may be used. The two sheet materials may be the same type of sheet material, or may be different types of sheet material. The material for forming this sheet material is not limited to a specific material, but the composite sheet material can be softened when bonded to each other by heat fusion without using an adhesive or the like. For example, heat fusion such as polyolefin resin is possible. It is preferable that the resin is contained.
　上記の凸部は一方のシート材にのみ形成してもよいが、両方のシート材にそれぞれ凸部が形成してあると、複合シート材が一層柔らかくなって好ましい。この場合、各シート材の形成する凸部の位置や形状は、互いに異なっていてもよいが、同じ形状の凸部を対応する位置に形成すると、両シート材は、それぞれの凸部の周囲の平坦部分が互いに対面することとなり、この部分で両シート材を互いに接合できるので好ましい。 The above-mentioned convex portions may be formed only on one sheet material, but it is preferable that the convex portions are formed on both sheet materials because the composite sheet material becomes softer. In this case, the positions and shapes of the convex portions formed by the respective sheet materials may be different from each other, but when the convex portions having the same shape are formed at the corresponding positions, both sheet materials are arranged around the respective convex portions. Since the flat portions face each other, both sheet materials can be joined to each other at this portion, which is preferable.
　上記の両シート材を互いに接合する手段としては、例えばホットメルト型接着剤等を用いることも可能であるが、加熱圧着等による熱溶着で接合すると、接着剤によるゴワつきを防止でき、柔らかな複合シート材が得られて好ましい。 As a means for joining the two sheet materials to each other, for example, a hot melt type adhesive can be used. However, when joining by heat welding such as thermocompression bonding, it is possible to prevent the adhesive from becoming stiff and soft. A composite sheet material is preferred because it is obtained.
　上記の凸部の周囲は、全周囲に亘って他のシート材と接合すると、弾性部材の伸縮にかかわらず、その凸部が一層良好に維持されて好ましい。
　しかし本発明では、例えばこの凸部の周囲のうちの一部が他のシート材の凸部と対応している場合など、他のシート材と接合していない部分があってもよい。即ち、上記の凸部の周囲は、この凸部が弾性部材の伸縮にかかわらず維持される程度に他のシート材と接合してあればよく、凸部の周囲のうちの一部のみで接合することも可能であり、この場合は複合シート材が一層柔らかくなる利点がある。 It is preferable that the periphery of the above-described convex portion is more satisfactorily maintained regardless of the expansion and contraction of the elastic member when it is joined to another sheet material over the entire periphery.
However, in the present invention, there may be a portion that is not joined to another sheet material, for example, when a part of the periphery of the convex portion corresponds to a convex portion of another sheet material. In other words, the periphery of the above-mentioned convex portion may be joined to another sheet material to such an extent that the convex portion is maintained regardless of the expansion and contraction of the elastic member, and only a part of the periphery of the convex portion is joined. In this case, there is an advantage that the composite sheet material becomes softer.
　上記の凸部は特定の形状に限定されず、平面視が円形や楕円形、長円形のほか、多角形なども採用できる。この凸部の形状を上記の弾性部材の長さ方向と交差する方向に、例えば直交方向に長く形成すると、この凸部があたかも襞のような外観となって好ましい。 The above-mentioned convex part is not limited to a specific shape, and a plan view may be a circle, an ellipse, an oval, or a polygon. If the shape of the convex portion is formed long in the direction intersecting with the length direction of the elastic member, for example, in the orthogonal direction, the convex portion is preferable as it looks as if it is a heel.
　上記の凸部は、シート材の任意の部位に形成することができ、シート材の略全面に亘って形成することも可能であり、或いは、幅方向の中間部に形成し、少なくとも一方の側縁部に沿ってこの凸部を有しない平坦部を形成することも可能である。この場合、上記の弾性部材は、この平坦部で両シート材の間に配置してもよい。 The convex portion can be formed in any part of the sheet material, and can be formed over substantially the entire surface of the sheet material, or formed in an intermediate portion in the width direction and at least one side. It is also possible to form a flat part that does not have this convex part along the edge part. In this case, you may arrange | position said elastic member between both sheet materials in this flat part.
　上記の凸部は任意の手段によりシート材に形成することができるが、例えば上記の本発明２のように、賦形ロール等を用いて形成すると、第１シート材に所望形状の凸部が賦形ロールの表面の凹凸形状により成型され、しかもこの凸部の周囲は第２シート材と接合されるので、この凸部が周囲の平坦な面で確りと保形され、より好ましい。 The convex portion can be formed on the sheet material by any means. For example, when the forming portion is formed using a shaping roll or the like as in the second aspect of the present invention, the convex portion having a desired shape is formed on the first sheet material. Since the surface of the shaping roll is molded according to the uneven shape, and the periphery of the convex portion is joined to the second sheet material, the convex portion is more securely retained on the peripheral flat surface, which is more preferable.
　この場合、ロール周面が平滑な接合用ロールを上記の賦形ロールの一方のロールに当接または近接させて配置し、この接合用ロールと上記の一方のロールとの間に、上記の凸部が形成された第１シート材と上記の第２シート材とを、上記の弾性部材を挟み込んだ状態で通過させて両シート材を互いに接合すると、上記の凸部の形成と、弾性部材の挟持およびシート材同士の接合を１工程で行うことができて好ましい。 In this case, a bonding roll having a smooth roll peripheral surface is disposed in contact with or close to one of the above-mentioned shaping rolls, and the above-mentioned convexity is provided between this bonding roll and the above-mentioned one roll. When the first sheet material on which the portion is formed and the second sheet material are passed with the elastic member sandwiched therebetween and the two sheet materials are joined to each other, the formation of the convex portion and the elastic member Nipping and joining of sheet materials can be performed in one step, which is preferable.
　また、両シート材にそれぞれ凸部を形成する方法としては、例えば上記の本発明２において、上記の賦形ロールとは別の、互いに平行に配置された一対のロールの各ロール周面に、対面位置で互いに噛み合う凹凸形状を形成して、両ロールにより第２の賦形ロールを構成し、この第２賦形ロールの両ロール間に上記の第２シート材を通過させて、この第２シート材に所定形状の第２凸部を形成したのち、この第２凸部を突出させた側とは反対側の表面を上記の第１シート材に重ね合わせる方法を採用することができる。 In addition, as a method of forming the convex portions on both sheet materials, for example, in the present invention 2 described above, on each roll peripheral surface of a pair of rolls arranged in parallel to each other, apart from the above-mentioned shaping roll, An uneven shape that meshes with each other at the facing position is formed, a second shaping roll is formed by both rolls, and the second sheet material is passed between both rolls of the second shaping roll, and this second After the second convex portion having a predetermined shape is formed on the sheet material, it is possible to employ a method in which the surface opposite to the side from which the second convex portion is projected is superposed on the first sheet material.
　この場合も、上記の賦形ロールの一方のロールと上記の第２賦形ロールの一方のロールとを互いに当接または近接させて配置し、両ロール間に上記の凸部が形成された第１シート材と第２凸部が形成された第２シート材とを、上記の弾性部材を挟み込んだ状態で通過させて両シート材を互いに接合すると、上記の凸部の形成と、弾性部材の挟持およびシート材同士の接合を１工程で行うことができて好ましい。 Also in this case, one roll of the above-mentioned shaping roll and one roll of the above-mentioned second shaping roll are arranged in contact with each other or close to each other, and the above-mentioned convex part is formed between both rolls. When the one sheet material and the second sheet material on which the second protrusions are formed are passed through the elastic member in between and the two sheet materials are joined together, the formation of the protrusions and the elastic member Nipping and joining of sheet materials can be performed in one step, which is preferable.
　上記の複合シート材は、弾性部材が伸長して引き伸ばされた場合であっても、上記の凸部が消失等することなく維持されるうえ、収縮しても凸部が過剰に折重なることがない。このため、この複合シート材を用いた使い捨て着用物品は、上記の弾性部材により装着者に対し良好にフィットしながらも、複合シート材が柔らかくゴワつくことがないので、良好な装着感が得られる。 Even if the above-mentioned composite sheet material is a case where the elastic member is stretched and stretched, the above-mentioned convex portions are maintained without disappearing, and even if contracted, the convex portions may be excessively folded. Absent. For this reason, the disposable wearing article using the composite sheet material fits well to the wearer with the above elastic member, but the composite sheet material is soft and not stiff, so that a good wearing feeling can be obtained. .
　特に、上記の複合シート材を腰部や股部に用いた場合に、上記の凸部が着用者の肌側に突出させてあると、この複合シート材と肌との接触面積が少なく済み、肌触りがよく、良好な感触が得られる。しかもこの複合シート材と肌との間で上記の凸部の周囲に空間が形成されるので、この空間により通気性が確保され、装着時の蒸れの発生が良好に防止される。 In particular, when the above-mentioned composite sheet material is used for the waist and crotch, the contact area between the composite sheet material and the skin can be reduced if the convex portion protrudes toward the skin of the wearer. And a good feel is obtained. Moreover, since a space is formed around the convex portion between the composite sheet material and the skin, the air permeability is ensured by this space, and the occurrence of stuffiness at the time of wearing is well prevented.
　また、上記の凸部が弾性部材の伸縮にかかわらず維持されるので、この凸部を形成しない場合に比べて、複合シート材の表面積が大きい。このため、いわゆる展開型使い捨ておむつのように、着用者の腰回りにフィットされる腰部が背部側部分と腹部側部分とに分離されており、この背部側部分と腹部側部分とのいずれか一方に係止鉤を備える面ファスナが付設されているとともに、他方にターゲットテープが付設してある場合には、このターゲットテープを上記の複合シート材で構成し、この複合シート材を、上記の係止鉤が着脱可能に係止される部位に配置し、その係止鉤が係止される際に上記の面ファスナと対面するように上記の凸部を形成していると、この凸部を形成した部分に上記の面ファスナの係合鉤を確りと係止することができて好ましい。 Moreover, since the above-mentioned convex portion is maintained regardless of the expansion and contraction of the elastic member, the surface area of the composite sheet material is larger than when the convex portion is not formed. For this reason, like a so-called deployable disposable diaper, the waist part fitted around the waist of the wearer is separated into a back part and an abdomen part, and either the back part or the abdomen part When the hook and loop fastener having the hook is attached to the other side and the target tape is attached to the other side, the target tape is made of the composite sheet material, and the composite sheet material is When the protrusion is disposed at a portion where the stopper rod is detachably locked, and the protrusion is formed so as to face the surface fastener when the locking rod is locked, the protrusion is It is preferable that the engaging hook of the surface fastener can be securely locked to the formed portion.
　本発明は上記のように構成され作用することから、次の効果を奏する。
　(１)上記の複合シート材は、弾性部材が伸長して引き伸ばされた場合であっても凸部が消失等することなく維持されており、収縮しても凸部が過剰に折重なることがないので、柔らかくゴワつくことがない。従ってこの複合シート材を用いた使い捨て着用物品は、弾性部材により装着者に対するフィット性を良好にできるうえ、着用時の感触を良好にすることができる。 Since the present invention is configured and operates as described above, the following effects can be obtained.
(1) In the above composite sheet material, even when the elastic member is stretched and stretched, the convex portion is maintained without disappearing, and the convex portion may be excessively folded even when contracted. Because there is no, it is not soft and sticky. Therefore, the disposable wearing article using this composite sheet material can improve the fit with respect to the wearer by the elastic member, and can also improve the feel when worn.
　(２)特に、上記の複合シート材を腰部や股部に用いた場合に、上記の凸部が着用者の肌側に突出させてあると、この複合シート材と肌との接触面積が少なく済むので肌触りがよく、着用時の感触を一層良好にできるうえ、互いに隣接する凸部同士間の間隙により、複合シート材と肌との間の通気性を確保でき、装着時の蒸れの発生を効果的に防止することができる。 (2) In particular, when the above composite sheet material is used in the waist and crotch region, the contact area between the composite sheet material and the skin is small when the above-mentioned convex portions are projected on the skin side of the wearer. As it is finished, it feels better and feels better when worn, and the gap between the adjacent convex parts ensures air permeability between the composite sheet material and the skin, which prevents the generation of stuffiness. It can be effectively prevented.

　上記の腰部(２)は背部側部分(2a)と腹部側部分(2b)とからなり、各部分(2a・2b)の両端の接合部(４)で互いに融着固定され、これにより腰部(２)が環状に形成してある。
　上記の腰部(２)は腰部用複合シート材(10)で構成されており、この腰部用複合シート材(10)は、互いに接合された、着用者の肌側の第１シート材(11)と外側の第２シート材(12)とを備え、さらに両シート材(11・12)間に配置された、例えばゴム弾性を備えた糸条体等の、長尺の弾性部材(13)を備えている。上記の第１シート材(11)には上下に長い第１凸部(14)が着用者の肌側に突出させて形成してあり、第２シート材(12)には同様の形状の第２凸部(15)が外方に突出させて形成してある。 The waist part (2) is composed of a back part (2a) and an abdomen part (2b) and is fused and fixed to each other at joints (4) at both ends of each part (2a, 2b). 2) is formed in an annular shape.
The lumbar part (2) is composed of a lumbar composite sheet material (10). The lumbar composite sheet material (10) is joined to the first sheet material (11) on the skin side of the wearer. And an outer second sheet material (12), and a long elastic member (13), such as a thread body with rubber elasticity, disposed between both sheet materials (11, 12). I have. The first sheet material (11) has a first protrusion (14) that is long in the vertical direction and protrudes toward the wearer's skin, and the second sheet material (12) has a first shape of the same shape. Two convex portions (15) are formed to protrude outward.
　図２と図３に示すように、上記の第１シート材(11)に形成された第１凸部(14)と、第２シート材(12)に形成された第２凸部(15)は、それぞれ他方のシート材側とは反対側に、即ち、互いに反対側へ突出する状態に形成してある。これらの各凸部(14・15)は、両シート材(11・12)同士の接合に先立って、予め各シート材(11・12)の互いに対応する位置に形成してあり、これらの凸部(14・15)の周囲で両シート材(11・12)が熱溶着やホットメルト型接着剤等により互いに接合してある。 As shown in FIG. 2 and FIG. 3, the first convex portion (14) formed on the first sheet material (11) and the second convex portion (15) formed on the second sheet material (12). Are formed on the opposite side to the other sheet material side, that is, in a state of projecting to the opposite side. Each of these convex portions (14, 15) is formed in advance in a position corresponding to each other of each sheet material (11, 12) prior to joining of both sheet materials (11, 12). The two sheet materials (11, 12) are joined to each other around the portion (14, 15) by heat welding, hot melt adhesive, or the like.
　上記の弾性部材(13)は、上記の両シート材(11・12)が互いに接合されている箇所に挟持されて、これらのシート材(11・12)に固定されている。この弾性部材(13)は、上記の腰部用複合シート材(10)の長さ方向に長く配置されており、一方、上記の凸部(14・15)は上記の腰部用複合シート材(10)の幅方向に長く形成され、従って弾性部材(13)の長さ方向と交差する方向に長く形成してある。 The elastic member (13) is sandwiched between the two sheet materials (11, 12) and fixed to these sheet materials (11, 12). The elastic member (13) is arranged long in the length direction of the waist composite sheet material (10), while the protrusions (14, 15) are the waist composite sheet material (10 ) In the width direction, and thus in the direction intersecting the length direction of the elastic member (13).
　なお例えば図２に示すように、上記の腰部用複合シート材(10)のうち、上記の股部(３)を取付けた部位では、この股部(３)に配置された吸収体(５)に皺が生じないように、上記の弾性部材(13)の収縮力を小さくする加工が施されていると好ましい。この弾性部材(13)の収縮力を小さくする加工としては、この部位の弾性部材(13)を、例えばヒートロールで加熱溶融させる加工や、カッターで切断する加工などを挙げることができる。 For example, as shown in FIG. 2, in the above-mentioned waist composite sheet material (10), in the portion where the above crotch portion (3) is attached, the absorbent body (5) disposed on this crotch portion (3). It is preferable that the elastic member (13) is processed so as to reduce the contraction force so that wrinkles do not occur. Examples of the process for reducing the contractive force of the elastic member (13) include a process of heating and melting the elastic member (13) at this portion with a heat roll, a process of cutting with a cutter, and the like.

Moreover, the waist convex composite sheet material (10) is soft due to the first convex portion (14) and the second convex portion (15), and the waist portion (2) is worn by the first convex portion (14). Since the contact with the waist of the person is suppressed, the feel when worn is made good. Moreover, the air permeability between a pants-type diaper (1) and a wearer's skin is ensured by the space between mutually adjacent 1st convex parts (14). Moreover, since the first convex portion (14) and the second convex portion (15) are pre-formed on each sheet material (11, 12), they are maintained even when the elastic member (13) is extended. The function is demonstrated well.
　なおこの実施形態では、上記の第１凸部(14)が縦長に形成してあるので、上記の第１凸部(14)間の空間も縦長に形成され、良好な通気性が確保されて好ましい。しかし本発明では、この第１凸部(14)を、例えば円形等に形成して上下方向に並べてもよく、さらには、通気性を良好にできる範囲で、例えば千鳥状等、他の形態で配することも可能である。 In this embodiment, since the first convex portion (14) is formed in a vertically long shape, the space between the first convex portions (14) is also formed in a vertically long shape, and good air permeability is ensured. preferable. However, in the present invention, the first protrusions (14) may be formed in, for example, a circular shape and arranged in the vertical direction. Further, as long as the air permeability can be improved, the first protrusions (14) may have other forms such as a staggered shape. It is also possible to arrange them.
　一方、上記の股部(３)は、図２に示すように一端が上記の背部側部分(2a)の複合シート材(10)に固定されており、他端が図外の腹部側部分の複合シート材に固定されている。この股部(３)は吸収体(５)を備えており、この吸収体(５)を表面シート(６)で覆ってある。また、この股部(３)の両側縁に沿って、立体ギャザー形成用複合シート材(20)がそれぞれ付設してある。 On the other hand, as shown in FIG. 2, the crotch portion (3) has one end fixed to the composite sheet material (10) of the back portion (2a) and the other end of the abdomen portion not shown. It is fixed to the composite sheet material. The crotch portion (3) includes an absorbent body (5), and the absorbent body (5) is covered with a top sheet (6). In addition, a composite sheet material (20) for forming a three-dimensional gather is provided along both side edges of the crotch portion (3).
　図２と図４に示すように、上記の立体ギャザー形成用複合シート材(20)は、互いに接合された第１シート材(21)と第２シート材(22)とを備えており、これら両シート材(21・22)間に配置された、例えばゴム弾性を備えた糸条体等の、長尺の弾性部材(23)を備えている。 As shown in FIGS. 2 and 4, the above-described composite sheet material for forming a three-dimensional gather (20) includes a first sheet material (21) and a second sheet material (22) joined together, A long elastic member (23) such as a thread body having rubber elasticity, for example, disposed between the two sheet materials (21, 22) is provided.

　上記の展開型おむつ(60)を着用する際には、上記の背部側部分(61a)が着用者の腰回りに沿って回され、上記の係合テープ(63)の面ファスナ(64)に植設された係止鉤が、腹部側部分(61b)に付設された上記のターゲットテープ(65)に係止されて、腰部(61)が環状にされる。このとき、このターゲットテープ(65)を構成する複合シート材(70)は、上記の第１シート材(71)に凸部(74)が形成されているので広い面積となっており、上記の係止鉤がこのターゲットテープ(65)に確りと固定される。また、上記の複合シート材(70)は弾性部材(73)を備えているので、上記の環状となった上記の腰部(61)は、この弾性部材(73)と上記の背部側部分(61a)が備える弾性部材とで良好な伸縮性を備えており、良好なフィット性が発揮される。 When wearing the unfolded diaper (60), the back side portion (61a) is turned around the waist of the wearer, and is attached to the surface fastener (64) of the engagement tape (63). The implanted locking rod is locked to the target tape (65) attached to the abdomen side portion (61b), and the waist portion (61) is formed into an annular shape. At this time, the composite sheet material (70) constituting the target tape (65) has a large area because the convex portion (74) is formed on the first sheet material (71). The locking rod is securely fixed to the target tape (65). Further, since the composite sheet material (70) includes the elastic member (73), the annular waist portion (61) is formed between the elastic member (73) and the back portion (61a). The elastic member is provided with good stretchability and exhibits good fit.
　上記の実施形態で説明した複合シート材とその製造方法および使い捨て着用物品は、本発明の技術的思想を具体化するために例示したものであり、各部材の材質や形状、構造、配置、寸法、製造手順などをこれらの実施形態のものに限定するものではなく、本発明の特許請求の範囲内において種々の変更を加え得るものである。 The composite sheet material, the manufacturing method thereof, and the disposable wearing article described in the above embodiment are illustrated in order to embody the technical idea of the present invention, and the material, shape, structure, arrangement, and dimensions of each member. The manufacturing procedure and the like are not limited to those of these embodiments, and various modifications can be made within the scope of the claims of the present invention.
　例えば上記の実施形態では、上記の成形ロール部で第１シート材に凸部を形成するとともに、弾性部材を挟持した状態で第１シート材と第２シート材を互いに接合した。しかし本発明の複合シート材は、予め凸部を形成した第１シート材の片面に弾性部材を配置したのち、必要に応じて凸部を形成した第２シート材を重ね合せ、その後に接合用ロール等により両シート材を互いに接合させてもよい。或いは、平滑な第２シート材の片面に弾性部材を配置したのち、予め凸部を形成した第１シート材を重ね合せ、その後に両シート材を互いに接合することも可能である。 For example, in the above-described embodiment, the first sheet material and the second sheet material are bonded to each other while the convex portion is formed on the first sheet material by the molding roll portion and the elastic member is sandwiched. However, in the composite sheet material of the present invention, after the elastic member is arranged on one side of the first sheet material on which the convex portions are formed in advance, the second sheet material on which the convex portions are formed is superposed if necessary, and then the joining is performed. Both sheet materials may be joined together by a roll or the like. Alternatively, it is also possible to dispose the elastic member on one side of the smooth second sheet material, then superimpose the first sheet material on which the convex portions are formed in advance, and then join the two sheet materials together.
　また上記の実施形態では一方向に長い凸部や平面視で円形の凸部を形成した複合シート材について説明した。しかし本発明では他の形状の凸部を形成したものであってもよく、その凸部の配置も上記の実施形態のものに限定されない。
　また上記の実施形態では、第１シート材と第２シート材とを加熱圧着により互いに接合した。しかし本発明では、ホットメルト剤などの接着剤により両シート材を互いに接合させたものであってもよい。 In the above-described embodiment, the composite sheet material in which convex portions that are long in one direction or circular convex portions in plan view are formed has been described. However, in the present invention, convex portions having other shapes may be formed, and the arrangement of the convex portions is not limited to that of the above embodiment.
In the above embodiment, the first sheet material and the second sheet material are joined to each other by thermocompression bonding. However, in the present invention, both sheet materials may be bonded to each other by an adhesive such as a hot melt agent.
　また上記の実施形態では、弾性部材が糸条体である場合について説明した。しかし本発明ではテープ状の弾性部材を用いることも可能である。
　また上記の実施形態では、いずれも使い捨て着用物品がおむつである場合について説明した。しかし本発明の使い捨て着用物品は、おむつカバー、生理用ナプキン、失禁パッド等、他の使い捨て着用物品であってもよいことは、言うまでもない。 In the above embodiment, the case where the elastic member is a thread body has been described. However, in the present invention, it is also possible to use a tape-like elastic member.
Moreover, in said embodiment, all demonstrated the case where a disposable wearing article was a diaper. However, it goes without saying that the disposable wearing article of the present invention may be other disposable wearing articles such as a diaper cover, a sanitary napkin, and an incontinence pad.
　本発明の複合シート材とこれを用いた着用物品は、優れたフィット性を備えなから、着用時の感触を良好にするとともに、着用者の肌との間の通気性を良好に確保して蒸れの発生を効果的に防止できるので、使い捨ておむつや生理用ナプキンなどの使い捨て着用物品に特に好適に用いられるが、他の使い捨て着用物品にも有用である。 Since the composite sheet material of the present invention and the wearing article using the same do not have an excellent fit, the feel at the time of wearing is made good and the air permeability between the wearer's skin is well secured. Since the occurrence of stuffiness can be effectively prevented, it is particularly suitably used for disposable wearing articles such as disposable diapers and sanitary napkins, but is also useful for other disposable wearing articles.
