Description
本願は、使い捨て着用物品に関し、特にパンツ型の着用物品に関する。 The present application relates to a disposable wearing article, and particularly to a pants-type wearing article.
従来、パンツ型の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、パンツ部材の前後身頃の相対する両側縁部を接合して形成されたパンツ型使い捨ておむつであって、両側縁部の接合部が、両側縁部の長手方向に沿って、接合部の長手方向と交差する方向に長くなるように配列された多数の接合線により形成されており、且つ、接合線の配列間隔が、ウエスト周り開口部近傍及び脚周り開口部近傍の接合部において、他の接合部よりも密になっているパンツ型使い捨ておむつが開示されている。 Conventionally, pants-type disposable wearing articles are known. For example, Patent Document 1 discloses a pants-type disposable diaper formed by joining opposite side edges of front and rear bodies of a pant member, where the joints of the side edges are along the longitudinal direction of the side edges. , Formed by a large number of joint lines arranged so as to be long in a direction intersecting with the longitudinal direction of the joint portion, and the joint line is arranged in the vicinity of the opening around the waist and the vicinity of the leg opening. The pants type disposable diaper which is denser than the other joints is disclosed.
特許文献１には、ウエスト周り開口部近傍及び脚周り開口部近傍の接合部において、接合線の配列間隔を他の接合部よりも密にすることにより、着用時に不用意に引き裂かれることがなく、さらに、廃棄時には容易に引き剥がすことができる接合部を有するパンツ型使い捨ておむつが提供されることが開示されている。しかし、通常パンツ型使い捨ておむつを廃棄する際には、ウエスト周り開口部の接合部近傍を引っ張って前後身頃の相対する側縁部を引き破る。このため、ウエスト周り開口部近傍の接合線の配列間隔を他の接合部よりも密にすると、パンツ型使い捨ておむつを廃棄する際、ウエスト周り開口部近傍を引き破りにくくなるという問題が生じる。 In patent document 1, it is not inadvertently tearing at the time of wear by making the arrangement | sequence space | interval of a joining line denser than the other junction part in the junction part of waist vicinity vicinity and leg periphery opening vicinity. Furthermore, it is disclosed that a pants-type disposable diaper having a joint that can be easily peeled off when discarded is provided. However, when a normal pants-type disposable diaper is discarded, the side edges of the front and rear bodies are torn apart by pulling the vicinity of the joint of the opening around the waist. For this reason, when the arrangement | sequence space | interval of the joining line of the waist circumference opening part vicinity is made denser than another joining part, when discarding a pants-type disposable diaper, the problem of becoming difficult to tear the waist circumference opening part vicinity arises.
本発明は使用中での側縁部からの不用意な引き裂きを防止しつつ、廃棄するとき側縁部を容易に引き破ることが可能な使い捨て着用物品の提供を課題とする。 An object of the present invention is to provide a disposable wearing article that can easily tear the side edge when discarded, while preventing inadvertent tearing from the side edge during use.
本発明は、縦方向と横方向を有し、前ウエスト域と、後ウエスト域と、前後ウエスト域の間に位置する股間域とを備え、前ウエスト域の側縁部と後ウエスト域の側縁部とが、縦方向に延びる一対の接合領域において互いに接合されてウエスト開口と一対のレッグ開口とが形成される使い捨て着用物品に関する。 The present invention has a longitudinal direction and a lateral direction, and includes a front waist region, a rear waist region, and a crotch region located between the front and rear waist regions, and a side edge of the front waist region and a side of the rear waist region The present invention relates to a disposable wearing article in which an edge portion is joined to each other in a pair of joining regions extending in a longitudinal direction to form a waist opening and a pair of leg openings.
本発明の使い捨て着用物品は、前後ウエスト域の側縁部に沿って接合領域がウエスト開口を形成するウエスト開口縁からレッグ開口を形成するレッグ開口縁に至り、接合領域には、縦方向に間隔を置いて配列されて前ウエスト域と後ウエスト域とを接合する複数の融着部と、隣接する融着部どうしの間隔が他の隣接する融着部どうしの間隔よりも大きい広間隙部とが含まれ、融着部はそれぞれ横方向に湾曲する曲線部を有し、広間隙部が、ウエスト開口を形成するウエスト開口縁と、レッグ開口を形成するレッグ開口縁との間において、ウエスト開口縁寄りに位置することを特徴とする。このように、前後ウエスト域を接合する融着部どうしの間隔が大きい広間隙部をウエスト開口縁寄りに配置すれば、使い捨て着用物品を廃棄するときウエスト開口縁の接合領域付近を引っ張ると、ウエスト開口縁を破った際の力が、広間隙部を経ることでレッグ開口側に向けて伝わり易く、さらに、その力を受けて曲線部を有する各融着部を経ることで、途中でひっかかったり、力の向きが変わったりすることを抑えつつ、ウエスト開口縁を破った際の力をレッグ開口縁まで伝えることができるので、使い捨て着用物品を容易に引き破ることができる。また、広間隙部とウエスト開口縁との間に融着部を有することで、ウエスト開口縁付近が捲れたり、ウエスト開口縁付近が捲れることに伴って着用中にウエスト開口縁に裂け目が発生したりすることを防ぐことができる。 The disposable wearing article of the present invention has a leg opening edge which forms a leg opening from a waist opening edge where the joining area forms a waist opening along the side edge of the front and rear waist area, and the joining area is spaced in the vertical direction. And a plurality of fusion portions that join the front waist region and the rear waist region, and a wide gap portion in which an interval between adjacent fusion portions is larger than an interval between other adjacent fusion portions. Each of the fused portions has a curved portion that curves in the lateral direction, and the wide gap portion is located between the waist opening edge that forms the waist opening and the leg opening edge that forms the leg opening. It is located near the edge. In this way, if a wide gap portion with a large gap between the fusion portions joining the front and rear waist regions is arranged near the waist opening edge, when the disposable wearing article is discarded, the vicinity of the joining region of the waist opening edge is pulled, The force at the time of breaking the opening edge is easily transmitted to the leg opening side through the wide gap part, and further, it is caught in the middle by passing through each fusion part having a curved part under the force. Since the force at the time of breaking the waist opening edge can be transmitted to the leg opening edge while suppressing the change of the direction of the force, the disposable wearing article can be easily torn. In addition, by having a fused part between the wide gap part and the waist opening edge, a tear occurs at the waist opening edge during wearing as the vicinity of the waist opening edge is curled or the vicinity of the waist opening edge is curled Can be prevented.
請求項２に係る発明では、さらに股間域から前後ウエスト域に向けて延在する吸収構造体を備え、吸収構造体に吸収コアが含まれ、広間隙部が、ウエスト開口縁と、吸収コアの縦方向両端に位置するコア端部に接して横方向に延びる仮想接線との間に位置する。一般に、吸収コアとウエスト開口縁の間に位置する前後ウエスト域は伸びやすいので、大きく引っ張らないと前後ウエスト域を引き剥がせないが、吸収コアとウエスト開口縁の間に広間隙部を配置すれば、前後ウエスト域を大きく引っ張ることなく容易に前後ウエスト域を引き剥がすことができる。
請求項３に係る発明では、前後ウエスト域に互いに重なり合う複数枚のシート部材が含まれ、接合領域において広間隙部と広間隙部の縦方向両端に位置する融着部とが配置される領域に含まれるシート部材の枚数の方が、接合領域の残余の領域に含まれるシート部材の枚数よりも多い。このように融着部が配置される領域に含まれるシート部材の枚数が多いことで、融着部が配置される領域のシール強度を上げることができ、また、シート部材の枚数が多い領域に広間隙部を有することで、シート部材の枚数が多い領域の強度が出過ぎて破りにくくなることが防止される。なお、本願でシート部材の枚数というときは、異なるシート部材を複数枚重ねたときの枚数を意味するだけでなく、同一のシート部材を折り返して複数回折り重ねたときの層数も意味する。
請求項４に係る発明では、前後ウエスト域に、横方向に延びる複数条のウエスト弾性部材が配置され、少なくとも１条のウエスト弾性部材が広間隙部を横断し、横方向において前後ウエスト域の末端まで延在する。これにより、広間隙部の横方向両外側に位置するシート部材がウエスト弾性部材の収縮により丸まり、着用物品を使用しているとき、丸まったシート部材により広間隙部が被覆され、誤って破れが生じることを防止できる。
請求項５に係る発明では、複数の融着部の形状が半円状であり、融着部は、半円の直線部が接合領域において縦方向に延びる仮想直線上に並ぶ。このように半円状の融着部の直線部が縦方向に並ぶことで、縦方向に引き裂く際に力を伝え易くなる。
請求項６に係る発明では、半円状の融着部の曲線部が、使い捨て着用物品の横方向外側に向くようにして配置される。半円状の融着部の曲線部は角部を有さないので、横方向への力の分散を抑制して縦方向への力が伝わりやすくなる。
請求項７に係る発明では、広間隙部の上端とウエスト開口縁との間に円状または楕円状の融着部が少なくとも１つ位置し、広間隙部の下端とレッグ開口縁との間に半円状の融着部が複数配置され、半円状の融着部の直線部が接合領域において縦方向に延びる仮想直線上に並び、曲線部が使い捨て着用物品の横方向外側に向くようにして配置される。このようにすれば、円状の融着部によりウエスト開口縁の不用意な破断が防止される一方、半円状の融着部を起点として使用済みの着用物品を容易に破ることができる。
請求項８に係る発明では、融着部において、縦方向に接合領域を引き裂くための力よりも、横方向に接合領域を引き裂くための力の方が大きい。これにより、シート部材の強度が低い部分でも融着部強度が低く設定され、力が横方向に逃げにくいため、接合領域１５が縦方向に引き裂けやすく、横裂けしにくくなる。
請求項９に係る発明では、広間隙部の縦方向両端に位置する２つの融着部の間の距離Ｌ１と、広間隙部の縦方向両端に位置する２つの融着部のうち、ウエスト開口縁に近い側の融着部において広間隙部に接する点と、広間隙部とウエスト開口縁との間に配置された融着部のうち、ウエスト開口縁に最も近い融着部においてウエスト開口縁に最も近い点との間の距離Ｌ２とを比較したとき、距離Ｌ１の方が距離Ｌ２よりも大きい。これにより、ウエスト部の不用意な破断を防止しつつも、使用済みの着用物品を容易に破ることができる。
請求項１０に係る発明では、広間隙部の縦方向寸法が広間隙部とウエスト開口縁との間の距離よりも大きい。これにより、ウエスト部の不用意な破断を防止しつつも、使用済みの着用物品を容易に破ることができる。
The invention according to claim 2 further includes an absorbent structure that extends from the crotch region toward the front and rear waist region, the absorbent structure includes an absorbent core, and the wide gap portion includes the waist opening edge and the absorbent core. It is located between virtual tangents that extend in the horizontal direction in contact with the core ends located at both ends in the vertical direction. In general, the front and rear waist areas located between the absorbent core and the waist opening edge are easy to stretch, so the front and rear waist areas cannot be peeled off unless they are pulled greatly, but a wide gap is placed between the absorbent core and the waist opening edge. Thus, the front and rear waist regions can be easily peeled off without greatly pulling the front and rear waist regions.
In the invention according to claim 3, a plurality of sheet members overlapping each other are included in the front and rear waist regions, and a wide gap portion and a fusion portion located at both longitudinal ends of the wide gap portion are arranged in the joining region. The number of sheet members included is greater than the number of sheet members included in the remaining area of the joining area. In this way, the large number of sheet members included in the area where the fusion part is arranged can increase the seal strength of the area where the fusion part is arranged, and the area where the number of sheet members is large. By having the wide gap portion, it is possible to prevent the strength of the region where the number of sheet members is large from becoming excessive and difficult to break. In the present application, the number of sheet members means not only the number of sheets when different sheet members are stacked, but also the number of layers when the same sheet member is folded and folded multiple times.
In the invention according to claim 4, a plurality of waist elastic members extending in the lateral direction are disposed in the front and rear waist region, at least one waist elastic member traverses the wide gap portion, and the end of the front and rear waist region in the lateral direction. Extend to. As a result, the sheet members positioned on both lateral sides of the wide gap portion are rounded due to the shrinkage of the waist elastic member, and when the wearing article is used, the wide gap portion is covered by the rounded sheet member, and is accidentally torn. It can be prevented from occurring.
In the invention according to claim 5, the shape of the plurality of fused portions is semicircular, and the fused portions are arranged on a virtual straight line in which the semicircular straight portions extend in the longitudinal direction in the joining region. Thus, it becomes easy to transmit a force when tearing in the vertical direction by arranging the straight portions of the semicircular fused portions in the vertical direction.
In the invention which concerns on Claim 6, it arrange | positions so that the curve part of a semicircle-shaped melt | fusion part may face the horizontal direction outer side of a disposable wearing article. Since the curved portion of the semicircular fusion portion does not have a corner portion, the force in the vertical direction is easily transmitted by suppressing the dispersion of the force in the horizontal direction.
In the invention according to claim 7, at least one circular or elliptical fusion part is located between the upper end of the wide gap part and the waist opening edge, and between the lower end of the wide gap part and the leg opening edge. A plurality of semicircular fused portions are arranged, the straight portions of the semicircular fused portions are arranged on a virtual straight line extending in the vertical direction in the joining region, and the curved portion is directed to the lateral outer side of the disposable wearing article. Arranged. In this way, the circular fused portion prevents the waist opening edge from being carelessly broken, while the used worn article can be easily broken starting from the semicircular fused portion.
In the invention which concerns on Claim 8, in the melt | fusion part, the force for tearing a joining area | region to a horizontal direction is larger than the force for tearing a joining area | region to the vertical direction. Thereby, even in a portion where the strength of the sheet member is low, the fused portion strength is set low, and the force does not easily escape in the lateral direction, so the joining region 15 is easily torn in the longitudinal direction and is not easily torn laterally.
In the invention according to claim 9, the waist opening of the distance L <b> 1 between the two fusion portions located at both longitudinal ends of the wide gap portion and the two fusion portions located at both longitudinal ends of the wide gap portion is provided. Of the fusion part disposed between the wide gap part and the waist opening edge, the waist opening edge at the fusion part closest to the waist opening edge among the points in contact with the wide gap part at the fusion part on the side close to the edge When the distance L2 between the points closest to is compared with the distance L1, the distance L1 is larger than the distance L2. Thereby, the used wearing article can be easily broken while preventing an inadvertent breakage of the waist portion.
In the invention which concerns on Claim 10, the vertical direction dimension of a wide clearance gap is larger than the distance between a wide clearance gap and a waist opening edge. Thereby, the used wearing article can be easily broken while preventing an inadvertent breakage of the waist portion.

The outer layer sheets 23 and 24 have a longitudinal dimension larger than the longitudinal dimension of the inner layer sheets 21 and 22, and extend outside the inner layer sheets 21 and 22 at the outer end edges 16 a and 17 a of the front and rear waist panels 16 and 17. The outer layer sheets 23, 24 extending to the outside of the inner layer sheets 21, 22 are folded back along the outer edge 16 a, 17 a and are fixed to the skin facing surfaces of the inner layer sheets 21, 22. That is, the inner layer sheets 21 and 22 and the folded outer layer sheets 23 and 24 are overlapped, so that the multi-layer zone 19 having a large number of sheet members is laterally extended along the outer edges 16a and 17a of the front and rear waist panels 16 and 17. It is formed in the direction X.
前後ウエストパネル１６，１７の内層シート２１，２２と外層シート２３，２４との間には、横方向Ｘに延びる複数条のウエスト弾性部材３３が配置されている。ウエスト弾性部材３３には弾性糸を用いることができる。弾性糸には、例えば繊度が約３００〜９４０ｄｔｅｘの弾性糸を用いることができ、伸長倍率が約１．５〜３．０倍になるようにして内層シート２１，２２と外層シート２３，２４との間にホットメルト接着剤で固定することができる。 A plurality of waist elastic members 33 extending in the lateral direction X are disposed between the inner layer sheets 21 and 22 and the outer layer sheets 23 and 24 of the front and rear waist panels 16 and 17. An elastic thread can be used for the waist elastic member 33. As the elastic yarn, for example, an elastic yarn having a fineness of about 300 to 940 dtex can be used, and the inner layer sheets 21 and 22 and the outer layer sheets 23 and 24 are set so that the expansion ratio is about 1.5 to 3.0 times. It is possible to fix with a hot melt adhesive.
吸収構造体１４は、縦長の略矩形状であって、肌対向面側に位置するトップシート３０と、非肌対向面側に位置するバックシート３１と、トップシート３０とバックシート３１の間に挟み込まれる吸収コア３２とを備える。吸収コア３２には本願が属する技術分野で公知のものを用いることができ、例えばフラッフパルプ等の吸収性繊維と、高吸収性ポリマーとの混合物を所定の形状に賦形した吸収コア３２を用いることができる。なお、図示例の吸収コア３２は砂時計型に賦形されているが、吸収コア３２の形状は図示例に限定されない。また、吸収コア３２の横方向Ｘ両外側には、脚回り弾性部材３４が縦方向Ｙに伸長された状態で配置されている。脚回り弾性部材３４は、トップシート３０とバックシート３１の間に挟み込まれている。 The absorbent structure 14 is a vertically long, substantially rectangular shape, and includes a top sheet 30 positioned on the skin facing surface side, a back sheet 31 positioned on the non-skin facing surface side, and between the top sheet 30 and the back sheet 31. And an absorption core 32 to be sandwiched. As the absorbent core 32, those known in the technical field to which the present application belongs can be used. For example, an absorbent core 32 obtained by shaping a mixture of absorbent fibers such as fluff pulp and a superabsorbent polymer into a predetermined shape is used. be able to. In addition, although the absorption core 32 of the example of illustration is shaped in the hourglass shape, the shape of the absorption core 32 is not limited to the example of illustration. Moreover, the leg-holes elastic member 34 is arrange | positioned in the state extended in the vertical direction Y at the horizontal direction X both outer side of the absorption core 32. FIG. The leg-hole elastic member 34 is sandwiched between the top sheet 30 and the back sheet 31.
前ウエストパネル１６と後ウエストパネル１７とは、それぞれの肌対向面を向い合せて重ね合わされ、前後ウエストパネル１６，１７の側縁部１６ｃ，１７ｃに縦方向Ｙに配置される接合領域１５において互いに接合され、ウエスト開口２５と一対のレッグ開口２７とが形成される。図２，３に示すように接合領域１５には、複数の融着部２９が縦方向Ｙに間隔を置いて一列配列されており、各融着部２９において前ウエストパネル１６と後ウエストパネル１７とが接合されている。融着部２９では、熱溶着または超音波溶着により、前後ウエストパネル１６，１７に含まれるシート部材どうしが溶着されている。融着部２９では前後ウエストパネル１６，１７に含まれるシート部材どうしが溶着されているので、前後ウエストパネル１６，１７に互いを引き離す力を作用させたときでも融着部２９は剥離せず、融着部２９の外周においてシート部材が裂ける。このように融着部２９の剥離は生じないので、おむつ１０を着用する際、前後ウエストパネル１６，１７に横方向Ｘへ力がかかったときでも、融着部２９が剥離して不用意に側縁部１６ｃ，１７ｃが破れることはない。また接合領域１５には、隣接する融着部２９どうしの間隔が、他の隣接する融着部２９どうしの間隔よりも大きい広間隙部４１が含まれている。広間隙部４１は、ウエスト開口縁２６とレッグ開口縁２８との間において、ウエスト開口縁２６に近い位置に配置されている。 The front waist panel 16 and the rear waist panel 17 are overlapped with each other facing the skin, and in the joint region 15 arranged in the longitudinal direction Y on the side edges 16c and 17c of the front and rear waist panels 16 and 17, respectively. By joining, a waist opening 25 and a pair of leg openings 27 are formed. As shown in FIGS. 2 and 3, a plurality of fused portions 29 are arranged in a row in the joining region 15 at intervals in the longitudinal direction Y, and the front waist panel 16 and the rear waist panel 17 are arranged in each fused portion 29. And are joined. In the fusion part 29, the sheet members included in the front and rear waist panels 16 and 17 are welded by heat welding or ultrasonic welding. Since the sheet members included in the front and rear waist panels 16 and 17 are welded to each other at the fusion part 29, the fusion part 29 does not peel even when the force is applied to the front and rear waist panels 16 and 17. The sheet member is torn at the outer periphery of the fusion part 29. As described above, the fusion part 29 does not peel off. Therefore, when the diaper 10 is worn, even if a force is applied to the front and rear waist panels 16 and 17 in the lateral direction X, the fusion part 29 peels off and carelessly occurs. The side edges 16c and 17c are not torn. Further, the bonding region 15 includes a wide gap portion 41 in which the interval between the adjacent fusion portions 29 is larger than the interval between the other adjacent fusion portions 29. The wide gap portion 41 is disposed at a position close to the waist opening edge 26 between the waist opening edge 26 and the leg opening edge 28.
前後ウエストパネル１６，１７の側縁部１６ｃ，１７ｃを引き破るために、ウエスト開口縁２６の接合領域１５近傍を掴んで前後ウエストパネル１６，１７を引き離す力（以下、引裂き力と呼ぶ）を作用させたとき、接合領域１５において広間隙部４１が配置された部分では、広間隙部４１の縦方向Ｙ両端に位置する２つの融着部２９に引裂き力が集中する。一方、接合領域１５の広間隙部４１以外の部分では、融着部２９の間隔が広間隙部４１より狭くなっているため、広間隙部４１と同等の引裂き力を作用させたとき、引裂き力は複数の融着部２９に分散されてしまう。このため、接合領域１５は広間隙部４１を起点として裂け目を生じ易い。さらに、広間隙部４１をウエスト開口縁２６寄りに配置することにより、使用済みのおむつ１０の側縁部１６ｃ，１７ｃを、ウエスト開口２５側から容易に破ることができる。また、融着部２９において、縦方向Ｙに接合領域１５を引き裂くための力よりも、横方向Ｘに接合領域１５を引き裂くための力の方が大きいことが好ましい。これにより、シート部材の強度が低い部分でも融着部強度が低く設定され、力が横方向Ｘに逃げにくいため、接合領域１５が縦方向Ｙに引き裂けやすく、横裂けしにくくなる。 In order to tear the side edge portions 16c and 17c of the front and rear waist panels 16 and 17, a force (hereinafter referred to as a tearing force) for grasping the vicinity of the joining region 15 of the waist opening edge 26 and separating the front and rear waist panels 16 and 17 is applied. When this is done, the tearing force concentrates on the two fused portions 29 located at both ends in the longitudinal direction Y of the wide gap portion 41 in the portion where the wide gap portion 41 is disposed in the bonding region 15. On the other hand, in the portion other than the wide gap portion 41 of the joining region 15, the gap between the fusion portions 29 is narrower than that of the wide gap portion 41, so that when the tear force equivalent to that of the wide gap portion 41 is applied, the tear force Are dispersed in the plurality of fused portions 29. For this reason, the joining region 15 tends to cause a tear starting from the wide gap portion 41. Furthermore, by arranging the wide gap portion 41 closer to the waist opening edge 26, the side edges 16c and 17c of the used diaper 10 can be easily broken from the waist opening 25 side. Further, in the fusion part 29, it is preferable that the force for tearing the joining region 15 in the lateral direction X is larger than the force for tearing the joining region 15 in the longitudinal direction Y. Thereby, even in a portion where the strength of the sheet member is low, the fused portion strength is set low, and the force does not easily escape in the lateral direction X, so the joining region 15 is easily torn in the longitudinal direction Y and is not easily torn laterally.
融着部２９の縦方向Ｙ及び横方向Ｘ寸法と、隣接する融着部２９どうしの間隔の制限は特にないが、通常１〜３ｍｍの範囲である。融着部２９の形状は縦長であることが好ましい。このようにすれば、おむつ１０の使用中に前後ウエストパネル１６，１７に横方向Ｘへ力が加わった際、縦長の融着部２９が横方向Ｘの力に対する抵抗となるので、融着部２９が剥離して不用意に側縁部１６ｃ，１７ｃが破れることが防止される。一方、おむつ１０を廃棄するために側縁部１６ｃ，１７ｃを引き破る際には、縦長の融着部２９を伝って破れが進行するので、おむつ１０を容易に引き破ることができる。広間隙部４１の縦方向Ｙ寸法も特に制限されないが、例えば広間隙部４１の両端に位置する融着部２９以外の融着部２９であって、互いに隣り合う融着部２９の間隔の１．５〜１０倍の寸法にすることができる。また、広間隙部４１の縦方向Ｙ寸法を、融着部２９の縦方向Ｙ寸法の２〜５倍にすることができる。 Although there are no particular limitations on the vertical dimension Y and the horizontal dimension X of the fused part 29 and the spacing between adjacent fused parts 29, it is usually in the range of 1 to 3 mm. The shape of the fused portion 29 is preferably vertically long. In this way, when a force is applied to the front and rear waist panels 16 and 17 in the lateral direction X during use of the diaper 10, the longitudinally fused portion 29 becomes a resistance against the force in the lateral direction X. 29 is peeled off and the side edges 16c and 17c are prevented from being inadvertently broken. On the other hand, when tearing the side edge portions 16c and 17c in order to discard the diaper 10, the tear progresses along the vertically long fused portion 29, so that the diaper 10 can be easily torn. The longitudinal Y dimension of the wide gap portion 41 is not particularly limited, but is, for example, a fusion portion 29 other than the fusion portion 29 located at both ends of the wide gap portion 41, and the interval between the adjacent fusion portions 29 is one. Dimension can be 5 to 10 times. In addition, the vertical dimension Y of the wide gap portion 41 can be 2 to 5 times the vertical dimension Y of the fused portion 29.
広間隙部４１は、ウエスト開口縁２６とレッグ開口縁２８との間において、レッグ開口縁２８よりもウエスト開口縁２６に近い位置に配置される。このとき、広間隙部４１の縦方向Ｙ両端に位置する２つの融着部２９の間の距離Ｌ１（すなわち、広間隙部４１の縦方向Ｙ寸法）と、広間隙部４１の縦方向Ｙ両端に位置する２つの融着部２９のうち、ウエスト開口縁２６に近い側の融着部２９において広間隙部４１に接する点と、広間隙部４１とウエスト開口縁２６との間に配置された融着部２９のうち、ウエスト開口縁２６に最も近い融着部２９においてウエスト開口縁２６に最も近い点との間の距離Ｌ２とを比較したとき、Ｌ１の方がＬ２よりも大きいことが好ましい（図３参照）。ウエスト開口縁２６近傍では融着強度が強く出がちであるが、距離Ｌ１（すなわち広間隙部４１の縦方向Ｙ寸法）が距離Ｌ２よりも大きいことで、ウエスト開口縁２６近傍の強度が出すぎることがない。一方ウエスト開口縁２６近傍の融着部２９を引き裂いた力で、距離Ｌ２よりも長い距離の広間隙部４１を通過することで、縦方向Ｙに伝わる力が増幅されやすくなる。したがって、広間隙部４１をこのような位置に配置すれば、ウエスト開口縁２６近傍の不用意な破断を防止しつつも、使用済みのおむつ１０を容易に破ることができる。 The wide gap portion 41 is disposed between the waist opening edge 26 and the leg opening edge 28 at a position closer to the waist opening edge 26 than the leg opening edge 28. At this time, the distance L1 between the two fused portions 29 located at both ends of the wide gap portion 41 in the vertical direction Y (that is, the vertical Y dimension of the wide gap portion 41) and the both ends of the wide gap portion 41 in the vertical direction Y. Of the two fusion parts 29 located at the side of the waist opening edge 26, the point being in contact with the wide gap part 41, and between the wide gap part 41 and the waist opening edge 26. When comparing the distance L2 between the fusion part 29 and the point closest to the waist opening edge 26 in the fusion part 29 closest to the waist opening edge 26, it is preferable that L1 is larger than L2. (See FIG. 3). In the vicinity of the waist opening edge 26, the fusion strength tends to be strong, but when the distance L1 (that is, the longitudinal Y dimension of the wide gap portion 41) is larger than the distance L2, the strength in the vicinity of the waist opening edge 26 is too high. There is nothing. On the other hand, the force transmitted in the longitudinal direction Y is easily amplified by passing through the wide gap portion 41 having a distance longer than the distance L2 by the force of tearing the fused portion 29 in the vicinity of the waist opening edge 26. Therefore, if the wide gap | interval part 41 is arrange | positioned in such a position, the used diaper 10 can be broken easily, preventing inadvertent fracture | rupture near the waist opening edge 26 vicinity.
また、広間隙部４１の縦方向Ｙ寸法を、広間隙部４１とウエスト開口縁２６との離間距離よりも大きくすることができる。広間隙部４１の縦方向Ｙ両端には融着部２９が必ず位置しているので、広間隙部４１とウエスト開口縁２６との間には、融着部２９が少なくとも１つ配置されている。このように広間隙部４１とウエスト開口縁２６との間に融着部２９を少なくとも１つ配置し、さらに広間隙部４１の縦方向Ｙ寸法を、広間隙部４１とウエスト開口縁２６との離間距離よりも大きくすることにより、ウエスト開口縁２６からの不用意な破断を防止しつつも、使用済みのおむつ１０を容易に破ることができる。 Further, the vertical dimension Y dimension of the wide gap portion 41 can be made larger than the separation distance between the wide gap portion 41 and the waist opening edge 26. Since the fusion part 29 is always located at both ends in the longitudinal direction Y of the wide gap part 41, at least one fusion part 29 is arranged between the wide gap part 41 and the waist opening edge 26. . In this way, at least one fusion part 29 is arranged between the wide gap part 41 and the waist opening edge 26, and the longitudinal dimension Y of the wide gap part 41 is determined between the wide gap part 41 and the waist opening edge 26. By making it larger than the separation distance, the used diaper 10 can be easily broken while preventing inadvertent breakage from the waist opening edge 26.
図３に示すように、複数の融着部２９それぞれの形状を半円状とすることができる。さらに、半円状の融着部２９の直線部が接合領域１５において縦方向Ｙに延びる仮想直線Ｐ上に並び、かつ、曲線部４２がおむつ１０の横方向Ｘ外側に向くようにして配置することができる。このようにすれば、半円状の融着部２９の直線部が縦方向Ｙに並ぶため、おむつ１０を破るとき縦方向Ｙに力を伝え易い。また、直線部と比較すると融着部２９の曲線部４２には力が伝わりにくいので、おむつ１０を破るときの力が縦方向Ｙ以外の方向に分散することが抑制される。別言すれば、各融着部２９が曲線部４２を有することで、前後ウエストパネル１６，１７の側縁部１６ｃ，１７ｃを引き破る際の力を途切れることなくレッグ開口縁２８に向けて伝えることができる。融着部２９を半円状にする場合、例えば円の半径を０．５〜１．５ｍｍとし、隣接する融着部２９の間隔を０．５〜２．０ｍｍにすることができるが、これに限定されない。また、複数の融着部２９の形状は半円状に限定されず、円形、楕円形、またはこれらの組合せにすることもできる。融着部２９の形状を楕円形にする場合、楕円形の長軸を縦方向Ｙに向けることが好ましい。 As shown in FIG. 3, the shape of each of the plurality of fused portions 29 can be a semicircular shape. Further, the semicircular fused portions 29 are arranged so that the straight portions thereof are arranged on a virtual straight line P extending in the longitudinal direction Y in the joining region 15 and the curved portion 42 faces the outside in the lateral direction X of the diaper 10. be able to. In this way, since the straight portions of the semicircular fused portion 29 are arranged in the vertical direction Y, it is easy to transmit force in the vertical direction Y when the diaper 10 is torn. Further, since the force is less likely to be transmitted to the curved portion 42 of the fused portion 29 as compared with the straight portion, the force when breaking the diaper 10 is suppressed from being dispersed in directions other than the longitudinal direction Y. In other words, since each fusion part 29 has the curved part 42, the force at the time of tearing the side edge parts 16c, 17c of the front and rear waist panels 16, 17 is transmitted to the leg opening edge 28 without interruption. be able to. When the fusion part 29 is semicircular, for example, the radius of the circle can be 0.5 to 1.5 mm, and the interval between the adjacent fusion parts 29 can be 0.5 to 2.0 mm. It is not limited to. Moreover, the shape of the some fusion | fusion part 29 is not limited to semicircle shape, It can also be circular, an ellipse, or these combination. When making the shape of the fusion | melting part 29 into an ellipse, it is preferable to orient | assign the elliptical long axis to the vertical direction Y. FIG.
複数の融着部２９の配列の変形例として、広間隙部４１の上端とウエスト開口縁２６との間に、円状または楕円状の融着部２９を少なくとも１つ配置し、広間隙部４１の下端とレッグ開口縁２８との間に、半円状の融着部２９を複数配置することができる（図５参照）。前述のように、直線部と比較すると曲線部４２には力が伝わりにくいので、広間隙部４１とウエスト開口縁２６との間に円状または楕円状の融着部２９を配置することにより、おむつ１０を使用しているときに、ウエスト開口縁２６が不用意に破断することを防止できる。一方、広間隙部４１とレッグ開口縁２８との間に、半円状の融着部２９を複数配置することにより、使用済みのおむつ１０を容易に破ることができる。 As a modification of the arrangement of the plurality of fused portions 29, at least one circular or elliptical fused portion 29 is disposed between the upper end of the wide gap portion 41 and the waist opening edge 26. A plurality of semicircular fused portions 29 can be arranged between the lower end of the lip and the leg opening edge 28 (see FIG. 5). As described above, since the force is not easily transmitted to the curved portion 42 as compared with the straight portion, by arranging the circular or elliptical fusion portion 29 between the wide gap portion 41 and the waist opening edge 26, When the diaper 10 is used, the waist opening edge 26 can be prevented from being carelessly broken. On the other hand, the used diaper 10 can be easily broken by arranging a plurality of semicircular fused portions 29 between the wide gap portion 41 and the leg opening edge 28.
本実施形態では、前後ウエストパネル１６，１７のそれぞれに横方向Ｘに伸長状態で配置した複数条のウエスト弾性部材３３のうち、少なくとも１条のウエスト弾性部材３３が広間隙部４１を横断し、横方向Ｘにおいて前後ウエストパネル１６，１７の末端１６ｄ，１７ｄまで延在している（図３参照）。広間隙部４１からおむつ１０の外側に向け横方向Ｘに延在するウエスト弾性部材３３は、おむつ１０を使用しているときでも収縮している。また、前後ウエストパネル１６，１７に配置されたウエスト弾性部材３３の両端は、前後ウエストパネル１６，１７の末端１６ｄ，１７ｄに沿って縦方向Ｙに延びる末端溶着線１８において間接的に接合されている。このため、図４に示すように、末端溶着線１８と接合領域１５との間に位置するシート部材が、ウエスト弾性部材３３の収縮により丸まる。広間隙部４１では前ウエストパネル１６と後ウエストパネル１７とは互いに溶着されていないので、おむつ１０の使用中に突起物等に引っ掛かり、誤って破れてしまうおそれがある。しかし、広間隙部４１に少なくとも１条のウエスト弾性部材３３を配置すれば、末端溶着線１８と接合領域１５との間で丸まったシート部材により広間隙部４１が被覆される。これにより、おむつ１０の使用中に突起物等が広間隙部４１に引っ掛かったとき、おむつ１０が誤って破れてしまうことが防止される。なお、図４では理解を容易にするために、広間隙部４１の奥に見える融着部２９及びその周辺のシート部材を仮想線で示し、また、内層シート２１，２２に折り重ねられた外層シート２３，２４の図示を省略している。 In the present embodiment, at least one waist elastic member 33 of the plurality of waist elastic members 33 arranged in the stretched state in the lateral direction X on each of the front and rear waist panels 16 and 17 crosses the wide gap portion 41. In the lateral direction X, it extends to the ends 16d and 17d of the front and rear waist panels 16 and 17 (see FIG. 3). The waist elastic member 33 extending in the lateral direction X from the wide gap portion 41 toward the outside of the diaper 10 is contracted even when the diaper 10 is used. Further, both ends of the elastic waist member 33 disposed on the front and rear waist panels 16 and 17 are indirectly joined at a terminal weld line 18 extending in the longitudinal direction Y along the terminal ends 16d and 17d of the front and rear waist panels 16 and 17. Yes. For this reason, as shown in FIG. 4, the sheet member positioned between the terminal weld line 18 and the joining region 15 is rounded by the contraction of the waist elastic member 33. Since the front waist panel 16 and the rear waist panel 17 are not welded to each other in the wide gap portion 41, the diaper 10 may be caught by protrusions or the like during use, and may be torn accidentally. However, if at least one waist elastic member 33 is disposed in the wide gap portion 41, the wide gap portion 41 is covered with a sheet member that is rounded between the terminal weld line 18 and the joining region 15. This prevents the diaper 10 from being accidentally torn when a projection or the like is caught on the wide gap portion 41 during use of the diaper 10. In FIG. 4, in order to facilitate understanding, the fused portion 29 that is visible in the back of the wide gap portion 41 and the surrounding sheet members are indicated by phantom lines, and the outer layer folded on the inner layer sheets 21 and 22. Illustration of the sheets 23 and 24 is omitted.
また、広間隙部４１とウエスト開口縁２６との間に、少なくとも１条のウエスト弾性部材３３を横方向Ｘに配置し、横方向Ｘにおいて前後ウエストパネル１６，１７の末端１６ｄ，１７ｄまで延在させることが好ましい。これにより、おむつ１０を使用しているとき、ウエスト開口縁２６に誤って裂け目が生じた場合でも、広間隙部４１とウエスト開口縁２６との間に横方向Ｘに配置したウエスト弾性部材３３により、裂け目が縦方向Ｙに進行することを抑制できる。これにより、ウエスト開口縁２６近傍の不用意な破断を防止しつつも、使用済みのおむつ１０を容易に破ることができる。 Further, at least one waist elastic member 33 is disposed in the lateral direction X between the wide gap portion 41 and the waist opening edge 26, and extends to the ends 16 d and 17 d of the front and rear waist panels 16 and 17 in the lateral direction X. It is preferable to make it. As a result, when the diaper 10 is used, even if a tear is accidentally generated in the waist opening edge 26, the waist elastic member 33 disposed in the lateral direction X between the wide gap portion 41 and the waist opening edge 26. , The progress of the tear in the longitudinal direction Y can be suppressed. Thus, the used diaper 10 can be easily broken while preventing inadvertent breakage in the vicinity of the waist opening edge 26.
再び図２を参照して、広間隙部４１を、ウエスト開口縁２６と、吸収構造体１４に含まれる吸収コア３２の縦方向Ｙ両端に位置するコア端部３２ａに接して横方向Ｘに延びる仮想接線Ｑとの間に配置することができる。一般に、吸収コア３２はウエスト開口縁２６から縦方向Ｙに離れた位置に配置され、吸収コア３２とウエスト開口縁２６の間には、ウエスト弾性部材３３が配置される。このため、おむつ１０のウエスト開口縁２６に沿って横方向Ｘに延びる領域は、吸収コア３２の横方向Ｘ両外側に延びる領域と比較して、横方向Ｘに伸長し易い。したがって、使用済みのおむつ１０を破るとき、おむつ１０のウエスト開口縁２６に沿って横方向Ｘに延びる領域を大きく伸長させないと破れが生じない。しかし、広間隙部４１を設けることにより、おむつ１０のウエスト開口縁２６に沿って横方向Ｘに延びる領域を大きく伸長させることなく破ることが可能になる。 Referring again to FIG. 2, the wide gap portion 41 extends in the lateral direction X in contact with the waist opening edge 26 and the core end portions 32 a located at both ends in the longitudinal direction Y of the absorbent core 32 included in the absorbent structure 14. It can be arranged between the virtual tangent line Q. In general, the absorbent core 32 is disposed at a position away from the waist opening edge 26 in the longitudinal direction Y, and a waist elastic member 33 is disposed between the absorbent core 32 and the waist opening edge 26. For this reason, the area | region extended in the horizontal direction X along the waist opening edge 26 of the diaper 10 is easy to extend | expand in the horizontal direction X compared with the area | region extended in the horizontal direction X both outer sides of the absorption core 32. Therefore, when the used diaper 10 is torn, unless the region extending in the lateral direction X along the waist opening edge 26 of the diaper 10 is greatly expanded, the torn does not occur. However, by providing the wide gap portion 41, the region extending in the lateral direction X along the waist opening edge 26 of the diaper 10 can be broken without greatly extending.
前述のように、前後ウエストパネル１６，１７では、外層シート２３，２４が外端縁１６ａ，１７ａに沿って折り返され、内層シート２１，２２の肌対向面に重なり合う重層ゾーン１９では、シート部材の枚数が多くなっている。したがって、接合領域１５のうち、重層ゾーン１９と重なる領域に含まれるシート部材の枚数は、接合領域１５の残余の領域（すなわち、重層ゾーン１９とレッグ開口縁２８の間の領域）に含まれるシート部材の枚数よりも多くなっている。本実施形態では、接合領域１５の重層ゾーン１９と重なる領域に、広間隙部４１と、広間隙部４１の縦方向Ｙ両端に位置する２つの融着部２９とを配置している。このように、シート部材の枚数が多い領域に広間隙部４１の縦方向Ｙ両端に位置する２つの融着部２９を配置することにより、融着部２９が配置された領域がおむつ１０の使用中に誤って破れてしまうことを防止できる。さらに、シート部材の枚数が多い領域に広間隙部４１を配置することにより、シート部材の枚数が多い領域の強度が出過ぎて破りにくくなることを防止できる。 As described above, in the front and rear waist panels 16 and 17, the outer layer sheets 23 and 24 are folded back along the outer end edges 16 a and 17 a, and in the multilayer zone 19 overlapping the skin facing surfaces of the inner layer sheets 21 and 22, The number is increasing. Therefore, the number of sheet members included in the region overlapping the multilayer zone 19 in the bonding region 15 is the sheet included in the remaining region of the bonding region 15 (that is, the region between the multilayer zone 19 and the leg opening edge 28). More than the number of members. In the present embodiment, the wide gap portion 41 and the two fusion portions 29 positioned at both ends in the longitudinal direction Y of the wide gap portion 41 are arranged in the region overlapping the multilayer zone 19 of the bonding region 15. As described above, by arranging the two fusion portions 29 located at both ends in the longitudinal direction Y of the wide gap portion 41 in the region where the number of sheet members is large, the region where the fusion portion 29 is disposed is used by the diaper 10. It can be prevented from being accidentally broken inside. Furthermore, by disposing the wide gap portion 41 in the region where the number of sheet members is large, it is possible to prevent the strength of the region where the number of sheet members is large from becoming excessive and difficult to break.
図６（ａ），（ｂ），（ｃ）は、おむつ１０の前ウエスト域１１と後ウエスト域１２とを接合領域１５において分離させるときに要する力を、引張り試験機１００（図６（ｃ）参照）を用いて測定する手順を示す図である。 6 (a), 6 (b), and 6 (c) show the force required to separate the front waist region 11 and the rear waist region 12 of the diaper 10 in the joining region 15 by the tensile testing machine 100 (FIG. 6 (c)). It is a figure which shows the procedure measured using reference).
図６（ａ）は、ウエスト弾性部材３３（図２参照）の収縮によって生じていたギャザーが消失する程度にまで緊張させた状態にあるおむつ１０から測定用試片９０を採取するときの採取位置を示している。おむつ１０は、前後ウエスト域１１，１２を重ね合わせ、おむつ１０の横方向Ｘ寸法を二分する縦中心線Ｍに平行する案内線９１に沿ってはさみで裁断する。案内線９１は、接合領域１５から少なくとも３０ｍｍ離間している。 FIG. 6A shows a sampling position when the measurement specimen 90 is sampled from the diaper 10 in a state where the gathers generated by the contraction of the waist elastic member 33 (see FIG. 2) are tensed to disappear. Is shown. The diaper 10 is formed by overlapping the front and rear waist regions 11 and 12 and cutting with scissors along a guide line 91 parallel to a longitudinal center line M that bisects the lateral X dimension of the diaper 10. The guide line 91 is separated from the joining region 15 by at least 30 mm.
図６（ｂ）は、引張り試験機１００の上部チャック９２と下部チャック９３とのそれぞれに、試片９０の前ウエスト域１１の一部と後ウエスト域１２の一部とを把持させた状態を示している。チャック９２と９３との離間寸法Ｄを２０ｍｍにセットし、チャック９２と９３の間の中央に試片９０の接合領域１５を位置させて、試片９０における前ウエスト域１１の頂縁１１ａおよび後ウエスト域１２の頂縁１２ａ（すなわちウエスト開口縁２６）から１５−２０ｍｍまでの部分９４を把持させた。 FIG. 6B shows a state in which a part of the front waist region 11 and a part of the rear waist region 12 of the specimen 90 are gripped by each of the upper chuck 92 and the lower chuck 93 of the tensile testing machine 100. Show. The separation dimension D between the chucks 92 and 93 is set to 20 mm, the joining region 15 of the specimen 90 is positioned in the center between the chucks 92 and 93, and the top edge 11a and the rear edge of the front waist region 11 in the specimen 90 A portion 94 from the top edge 12a (ie, the waist opening edge 26) of the waist region 12 to 15-20 mm was gripped.
図６（ｃ）は、下部チャック９３を固定し、上部チャック９２を５００ｍｍ／ｍｉｎの速度で上昇させる過程で観察された試片９０の挙動を示す写真である。試片９０では、チャック９２が上昇するに従い、前ウエスト域１１と後ウエスト域１２との接合領域１５における分離が進行する。 FIG. 6C is a photograph showing the behavior of the specimen 90 observed in the process of fixing the lower chuck 93 and raising the upper chuck 92 at a speed of 500 mm / min. In the specimen 90, the separation in the joining region 15 between the front waist region 11 and the rear waist region 12 proceeds as the chuck 92 rises.
図７（ａ），（ｂ）は、引張り試験機１００を用いて試片９０の前ウエスト域１１と後ウエスト域１２とを分離させる際に要した力の測定結果を例示する図である。測定は、２個のおむつ１０から作成した４つの試片９０について行った。また、測定に供したおむつ１０では、内層シート２１，２２及び外層シート２３，２４に、芯成分がポリプロピレン、鞘成分がポリエチレンであって、繊度が１．３ｄｔｅｘの複合繊維で形成され、単位面積当たり質量が１５ｇ／ｍ２のスパンボンド不織布を使用した。 FIGS. 7A and 7B are diagrams illustrating the measurement results of the force required when the front waist region 11 and the rear waist region 12 of the specimen 90 are separated using the tensile tester 100. FIG. The measurement was performed on four specimens 90 made from two diapers 10. Further, in the diaper 10 used for the measurement, the inner layer sheets 21 and 22 and the outer layer sheets 23 and 24 are formed of a composite fiber having a core component of polypropylene and a sheath component of polyethylene and a fineness of 1.3 dtex. A spunbonded non-woven fabric having a hit weight of 15 g / m 2 was used.
図７（ａ）は、図３に例示した半円形の接合領域１５を有するおむつ１０についての測定結果である。図７（ａ）の横軸は、ｍｍ単位で表す上部チャック９２の移動距離（ストローク）であり、縦軸は引張り試験機１００で検出された力（単位Ｎ）、すなわち前ウエスト域１１と後ウエスト域１２との分離に要した力である。図７（ａ）の紙面上方には、接合領域１５における融着部２９の配置パターンを図示している。ただし、図７（ａ）は測定例の１つであり、上部チャック９２のストロークと融着部２９の位置とが常に図示の関係にあるとは限らない。すなわち、図７（ａ）は、引張り試験機１００で検出される力のピークが、そのピークの直上に図示されている融着部２９の部分で現れることを示すものではない。図７（ａ）に示すように、測定開始後、引張り試験機１００で検出された力は２〜６Ｎの間で安定していた。その後、全ストロークの８０％を超えたとき一時的に８Ｎ以上に上昇するピークを２回生じた後、前ウエスト域１１と後ウエスト域１２とが完全に分離した。これは、前ウエスト域１１と後ウエスト域１２とを、ウエスト開口縁２６から破って分離させるとき、破り始めからレッグ開口縁２８の近くまで、２〜６Ｎの比較的小さな力で安定して破ることができることを意味している。なお、測定に供した４つの試片９０は、いずれも図７（ａ）と同様の結果を示した。 FIG. 7A shows a measurement result of the diaper 10 having the semicircular joining region 15 illustrated in FIG. The horizontal axis of FIG. 7A is the movement distance (stroke) of the upper chuck 92 expressed in mm, and the vertical axis is the force (unit N) detected by the tensile testing machine 100, that is, the front waist region 11 and the rear. This is the force required for separation from the waist region 12. An arrangement pattern of the fused portions 29 in the joining region 15 is shown in the upper part of the paper surface of FIG. However, FIG. 7A is one example of measurement, and the stroke of the upper chuck 92 and the position of the fused portion 29 are not always in the illustrated relationship. That is, FIG. 7A does not indicate that the force peak detected by the tensile tester 100 appears at the portion of the fused portion 29 illustrated immediately above the peak. As shown to Fig.7 (a), after the measurement start, the force detected with the tensile testing machine 100 was stable between 2-6N. Then, after the peak which rises to 8N or more temporarily was generated twice when exceeding 80% of the total stroke, the front waist region 11 and the rear waist region 12 were completely separated. This is because when the front waist region 11 and the rear waist region 12 are torn and separated from the waist opening edge 26, they are stably broken with a relatively small force of 2 to 6 N from the beginning of breaking to the vicinity of the leg opening edge 28. It means that you can. Note that the four specimens 90 used for the measurement all showed the same results as in FIG.
接合領域１５に半円形の融着部２９を図７（ａ）に示すパターンで配置したおむつ１０について、前ウエスト域１１と後ウエスト域１２のウエスト開口縁２６側を１５ｍｍずつ手で掴んで前後ウエスト域１１，１２を分離したところ、分離を開始した直後においてのみ手に抵抗を感じたが、その後はほぼ一様な力でスムーズに分離できた。また、このおむつ１０から採取した２０個の試片９０について一人の作業者が手で前ウエスト域１１と後ウエスト域１２とを分離したところ、前ウエスト域１１及び後ウエスト域１２のいずれにおいても、接合領域１５の延在方向から外れて裂けることはなかった。すなわち、接合領域１５の横裂けは生じなかった。 About the diaper 10 in which the semicircular fused portion 29 is arranged in the joining region 15 in the pattern shown in FIG. 7A, the front waist region 11 and the rear waist region 12 are gripped by the waist opening edge 26 side by 15 mm. When the waist regions 11 and 12 were separated, resistance was felt in the hand only immediately after the separation was started, but after that, it was smoothly separated with a substantially uniform force. Moreover, when one worker separated the front waist region 11 and the rear waist region 12 by hand for the 20 specimens 90 collected from the diaper 10, both the front waist region 11 and the rear waist region 12 are separated. In addition, the joining region 15 did not split apart from the extending direction. That is, the lateral tearing of the joining region 15 did not occur.
図７（ｂ）は、従来のパターンで融着部２９を接合領域１５に配列した比較例のおむつ１０について、前ウエスト域１１と後ウエスト域１２とを接合領域１５において分離させるときに要する力を測定した結果を表す図である。比較例のおむつ１０は、接合領域１５に三角形の融着部２９が図７（ｂ）に示すパターンで配列されている点を除き、図７（ａ）に示す測定で使用したおむつ１０と同じである。 FIG. 7B shows the force required to separate the front waist region 11 and the rear waist region 12 in the joining region 15 for the diaper 10 of the comparative example in which the fused portions 29 are arranged in the joining region 15 in a conventional pattern. It is a figure showing the result of having measured. The diaper 10 of the comparative example is the same as the diaper 10 used in the measurement shown in FIG. 7A except that the triangular fused portions 29 are arranged in the joining region 15 in the pattern shown in FIG. It is.
図７（ｂ）に示すように、比較例のおむつ１０では、測定開始後、引張り試験機１００で検出された力が急激に増加して約１４Ｎに達した後、徐々に４Ｎまで低下し、再度約１４Ｎまで急増した後、前ウエスト域１１と後ウエスト域１２とが完全に分離した。これは、前ウエスト域１１と後ウエスト域１２とをウエスト開口縁２６から破って分離させるとき、破り始めに大きな力が必要であり、その後も力の変動幅が大きいことを意味している。実際に、図７の（ｂ）の測定に供した比較例のおむつ１０の前後ウエスト域１１，１２を手で分離してみると、分離に要する力が全般的に高く、しかも力の大きさの変化が激しかった。また、比較例のおむつ１０個から採取した２０個の試片９０を一人の作業者が手で分離したところ、３個の試片について、前ウエスト域１１または後ウエスト域１２に横裂けが生じた。 As shown in FIG. 7 (b), in the diaper 10 of the comparative example, after the measurement is started, the force detected by the tensile tester 100 increases rapidly to reach about 14N, and then gradually decreases to 4N. After rapidly increasing to about 14N again, the front waist region 11 and the rear waist region 12 were completely separated. This means that when the front waist region 11 and the rear waist region 12 are torn and separated from the waist opening edge 26, a large force is required at the beginning of breaking and the force fluctuation range is large thereafter. Actually, when the front and rear waist regions 11 and 12 of the comparative diaper 10 used for the measurement of FIG. 7B are separated by hand, the force required for the separation is generally high and the magnitude of the force is large. The change of was intense. In addition, when 20 samples 90 collected from 10 diapers of the comparative example were separated by an operator by hand, lateral tearing occurred in the front waist region 11 or the rear waist region 12 for the three samples. It was.
