Description

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

従来、連結手段を介して前ウエスト域と後ウエスト域とを連結することによってパンツ型の形態をなす使い捨ての着用物品は公知である。例えば、特許文献１には、前後ウエスト域と、前後ウエスト域間に位置するクロッチ域とを有し、吸収体を有するおむつ本体と、一対の連結部材とを含む使い捨ての着用物品が開示されている。連結部材は、おむつ本体に固定された基端部と、基端部から延出する自由部とを有しており、基端部と自由部との境界線は、クロッチ域からウエスト開口側へ横方向の外側から内側へ向かうように傾斜している。   Conventionally, disposable wearing articles that are in the form of pants by connecting a front waist region and a rear waist region via a connecting means are known. For example, Patent Document 1 discloses a disposable wearing article that includes a front and rear waist region, a crotch region located between the front and rear waist regions, and includes a diaper body having an absorbent body and a pair of connecting members. Yes. The connecting member has a base end portion fixed to the diaper body and a free portion extending from the base end portion, and a boundary line between the base end portion and the free portion extends from the crotch region to the waist opening side. It inclines so that it may go inward from the outer side of a horizontal direction.

Or a loop element that can be locked to a hook element arranged on the diaper main body 14 side or the connecting member 30 (in that sense, a locked portion), or a diaper. This means a portion that can be detachably locked with 10 predetermined portions, and means a wider concept including an adhesive or the like than a general locking portion that means only a hook element. Similarly, as long as the central locking portion 27 is detachably engaged with the connecting member 30, it is either a hook element, a loop element, or an element that can be engaged or fastened, such as an adhesive. Also good.

図４及び図５を参照すると、後ウエスト域１２の外面（非肌対向面）において、おむつ１０の両側縁１４ｃ，１４ｄと連結部材３０の内側縁３０ｃとの間には、それぞれ、第３係止部５５が配置される。ここで、連結部材３０の内側縁３０ｃとは、連結部材３０が非展開状態（図４において実線で示す状態）にある場合の内側縁３０ｃの位置を示している。第３係止部５５は、おむつ本体１４のバックシート２２及び／又は連結部材３０の第１及び第２シート３５，３６に係止可能である。第３係止部５５は、おむつ１０の着用状態において、連結部材３０の自由部３２を横方向Ｘ外側へ展開した際に自由部３２の外面をおむつ１０の後ウエスト域１２に係止するものであり、縦方向Ｙにおいて基端部３１が位置する範囲に配置される。第３係止部５５を配置することによって、連結部材３０の自由部３２の基端部３１側を固定して位置ずれを防ぐことができるとともに、横方向Ｘに延出した状態に維持しやすくすることができる。なお、第３係止部５５は、上述した効果を奏する限りにおいて連結部材３０の基端部３１及び／又は自由部３２の外面に配置されていてもよい。   Referring to FIGS. 4 and 5, on the outer surface (non-skin facing surface) of the rear waist region 12, there is a third engagement between both side edges 14 c and 14 d of the diaper 10 and the inner edge 30 c of the connecting member 30. A stop 55 is arranged. Here, the inner edge 30c of the connecting member 30 indicates the position of the inner edge 30c when the connecting member 30 is in a non-deployed state (shown by a solid line in FIG. 4).

In the longitudinal direction Y, the base end portion 31 is disposed in a range. By disposing the third locking portion 55, it is possible to fix the base end portion 31 side of the free portion 32 of the connecting member 30 to prevent displacement, and it is easy to maintain the state extended in the lateral direction X. can do. In addition, the 3rd latching | locking part 55 may be arrange | positioned on the outer surface of the base end part 31 of the connection member 30, and / or the free part 32, as long as there exists an effect mentioned above.

図４を参照すると、一対の連結部材３０は、縦方向Ｙに沿って取り付けられ、縦中心線Ｐに関して対称となるように配置される。連結部材３０において、基端縁３０ａは、おむつ本体１４の後端縁１４ｂに一致している。一対の連結部材３０の内側縁３０ｃは、横方向Ｘにおいて互いに隣接しており、縦方向Ｙに延びるミシン目５１を介して連結されている。なお、一対の連結部材３０は、横方向Ｘに離間して配置されてもよい。一対の連結部材３０を離間した状態において、おむつ本体１４の横方向Ｘの中央部に配置する場合には、離間寸法が約５〜１５ｍｍであり、約１０ｍｍであることが好ましい。なお、一対の連結部材３０をおむつ本体１４の両側部に配置してもよい。なお、おむつ１０は、製造工程において、ミシン目５１が形成される位置において一対の連結部材３０を縦方向Ｙに切断し、横方向Ｘに隣接する一対の連結部材３０が互いに分離した状態であってもよい。   Referring to FIG. 4, the pair of connecting members 30 are attached along the vertical direction Y and are arranged so as to be symmetric with respect to the vertical center line P. In the connecting member 30, the base end edge 30 a coincides with the rear end edge 14 b of the diaper main body 14. The inner edges 30c of the pair of connecting members 30 are adjacent to each other in the horizontal direction X and are connected via a perforation 51 extending in the vertical direction Y. Note that the pair of connecting members 30 may be spaced apart in the lateral direction X. In a state where the pair of connecting members 30 are separated from each other, when the diaper main body 14 is disposed at the central portion in the lateral direction X, the separation dimension is about 5 to 15 mm, preferably about 10 mm. In addition, you may arrange | position a pair of connection member 30 in the both sides of the diaper main body 14. FIG. In the manufacturing process, the diaper 10 is in a state where the pair of connecting members 30 are cut in the vertical direction Y at the position where the perforation 51 is formed, and the pair of connecting members 30 adjacent in the horizontal direction X are separated from each other. May be.

連結部材３０とおむつ本体１４との長さ方向を一致させることによって、おむつ１０の生産ライン上においておむつ本体１４と連結部材３０とを機械方向へ連続して搬送して製造することができ、連続生産性に優れる。また、連結部材３０がベルト弾性体を有する場合にも、該ベルト弾性体の長さ方向が一致するため連続生産性に優れる。一対の連結部材３０が横方向Ｘに離間することなく互いに隣接している場合には、対となる連結部材３０を一体的に形成することができ、より生産性が向上する。おむつ本体１４の縦方向Ｙの寸法（長さ寸法）Ｌ１は、約４００〜１２００ｍｍであり、本実施形態では約８４０ｍｍである。連結部材３０の縦方向Ｙの寸法（長さ寸法）Ｌ２は、約１００〜１２００ｍｍであり、約４００〜１０００ｍｍであることが好ましく、本実施形態では約５５０ｍｍである。おむつ本体１４の横方向Ｘの寸法（幅寸法）Ｗ１は、約１５０〜４５０ｍｍであり、本実施形態では約３４０ｍｍである。連結部材３０の横方向Ｘの寸法（幅寸法）Ｗ２は約５０〜２００ｍｍで、本実施形態では約９０ｍｍである。連結部材３０の幅寸法Ｗ２が５０ｍｍ未満である場合、おむつ１０の着用状態において連結部材３０の位置が安定しないおそれがある。また、幅寸法Ｗ２が２００ｍｍ超えである場合、製造コストが高くなり、着用状態において着用者の脚の動きを妨げるおそれがある。   By matching the length direction of the connecting member 30 and the diaper main body 14, the diaper main body 14 and the connecting member 30 can be continuously conveyed in the machine direction on the production line of the diaper 10 and manufactured. Excellent productivity. Further, even when the connecting member 30 has a belt elastic body, the length direction of the belt elastic body is matched, so that continuous productivity is excellent. When the pair of connecting members 30 are adjacent to each other without being separated in the lateral direction X, the paired connecting members 30 can be integrally formed, and the productivity is further improved. The dimension (length dimension) L1 of the diaper main body 14 in the vertical direction Y is about 400 to 1200 mm, and in this embodiment is about 840 mm. The dimension (length dimension) L2 in the longitudinal direction Y of the connecting member 30 is about 100 to 1200 mm, preferably about 400 to 1000 mm, and in this embodiment is about 550 mm. The dimension (width dimension) W1 of the diaper main body 14 in the horizontal direction X is about 150 to 450 mm, and is about 340 mm in this embodiment. The dimension (width dimension) W2 of the connecting member 30 in the lateral direction X is about 50 to 200 mm, and is about 90 mm in this embodiment. When the width dimension W2 of the connecting member 30 is less than 50 mm, the position of the connecting member 30 may not be stable when the diaper 10 is worn. Moreover, when width dimension W2 exceeds 200 mm, manufacturing cost becomes high and there exists a possibility of preventing a wearer's leg movement in a wearing condition.

自由部３２の両側縁部は、縦方向Ｙに一定間隔をあけて断続的に形成される仮止め部５７を介しておむつ本体１４のバックシート２２と剥離可能に仮止めされる。仮止め部５７では、連結部材３０とバックシート２２とが、ソニックシールや接着剤等の接合手段によって互いに仮止めされている。自由部３２を仮止めすることにより、自由部３２がおむつ本体１４の側縁１４ｃ，１４ｄから外側へ延出するように展開されて、おむつ１０の運搬時や収容袋に収容する際に、不要な折り癖がついたり、製造工程においてトラブルの原因となったりするのを防止することができる。   Both side edge portions of the free portion 32 are temporarily fixed to the back sheet 22 of the diaper main body 14 through a temporary fixing portion 57 formed intermittently with a certain interval in the longitudinal direction Y. In the temporary fixing portion 57, the connecting member 30 and the back sheet 22 are temporarily fixed to each other by a joining means such as a sonic seal or an adhesive. By temporarily fixing the free part 32, the free part 32 is deployed so as to extend outward from the side edges 14c, 14d of the diaper main body 14, and is not necessary when the diaper 10 is transported or accommodated in a storage bag. It is possible to prevent creases and troubles in the manufacturing process.

It is about 43 degrees. The boundary line 31c may be curved, and in such a case, the inclination angle θ between the virtual straight line connecting both ends of the boundary line 31c and the horizontal center line Q is in the range of about 30 to 50 degrees. Since the base end portion 31 has such a shape, the connecting member 30 can be easily developed in the lateral direction X starting from the inclined edge, and can be easily pulled in the direction around the waist. When the inclination angle θ is less than 45 degrees, the free part 32 is likely to be deployed toward the waist opening 16, and when it is greater than 45 degrees, the free part 32 is likely to be deployed toward the crotch region 13.

The joining portion 75 includes a longitudinal joining portion (first joining portion) 81 extending in the first direction, a transverse joining portion (second joining portion) 82 extending in the second direction intersecting the first direction, and the longitudinal joining portion and the transverse. And an intermediate portion 83 located between the joint portion 82. Each of the first and second directions is a direction in which the boundary line 31c extends (in a case where the boundary line 31c is curved, a direction in which an imaginary straight line connecting both end edges of the boundary line 31c extends. ). A plurality of the joint portions 75 are discontinuously arranged in the length direction K, and the longitudinal joint portions 81 and the transverse joint portions 82 are alternately arranged in the length direction K.

This is a curved part. The first direction and the vertical center line P and the inclination angle are in the range of about 0 to 30 degrees, and the inclination angle α between the second direction and the vertical center line P is in the range of about 55 to 125 degrees. With respect to the longitudinal center line P, the inclination angle in the first direction is about 0 degree, and the inclination angle α in the second direction is about 90 degrees. Here, the inclination angle between the vertical center line P and the first direction refers to an angle of intersection formed by the vertical center line P and a virtual straight line extending in the first direction. The inclination angle α is an angle of intersection formed by the vertical center line P and a virtual straight line extending in the second direction. In addition, the inclination angle in the first direction being 0 degrees means that the first direction and the direction in which the longitudinal center line P extends coincide with each other.

長さ方向Ｋにおいて互いに隣り合う接合部７５の離間寸法（隣り合う接合部７５の間に位置する、融着手段の非接合部７６の距離）Ｒは、約０．５〜５ｍｍである。また、接合部７５の長さ方向（接合部７５の両端縁を結ぶ仮想直線が延びる方向）において、縦断接合部８１の寸法Ｍ１及び横断接合部８２の寸法Ｍ２の割合は、それぞれ、接合部７５の長さ寸法（仮想直線が延びる方向の寸法）Ｍの約２０〜５０％であり、本実施形態では、接合部７５の長さ寸法Ｍに対し、縦断接合部８１、横断接合部８２及び中間部８３の寸法Ｍ１〜Ｍ３が、それぞれ約１／３となっている。接合部７５の長さ寸法Ｍは、約３〜１５ｍｍであり、離間寸法Ｒの２倍以上であることが好ましい。なお、寸法Ｍ１〜Ｍ３の割合はこれに限られず、境界側接合域７０の内端部７４と外端部７３において、寸法Ｍ１，Ｍ２の割合が異なるようにしてもよく、例えば、外端部７３において縦断接合部８１の寸法Ｍ１の割合が横断接合部８２の寸法Ｍ２に比して高く、内端部７４において、横断接合部８２の寸法Ｍ２の割合が縦断接合部８１の寸法Ｍ１に比して高くなっていてもよい。   In the length direction K, the separation dimension (distance between the non-joining portions 76 of the fusion means located between the adjacent joining portions 75) R is about 0.5 to 5 mm. Further, in the length direction of the joint 75 (the direction in which the imaginary straight line connecting both edges of the joint 75 extends), the ratio of the dimension M1 of the longitudinal joint 81 and the dimension M2 of the transverse joint 82 is respectively the joint 75.

基端部３１において、角部接合域９０は、基端部３１の外端縁３１ａ及び外側縁３１ｂと、境界側接合域７０の外側縁７０ａとによって画成され、略三角形状をなしている。角部接合域９０は、境界側接合域７０よりも接合強度が低くなっている。本実施形態では、接合域３８の全域にホットメルト接着剤等の接着剤が塗布され、さらに、境界側接合域７０にのみ融着手段による接合部７５を形成することによって、角部接合域９０の接合強度が境界側接合域７０に比して低くなっている。なお、境界側接合域７０と角部接合域９０の両方に接合部７５を形成し、境界側接合域７０において接合強度が高くなるように、接合部７５の配置を密にしてもよい。   In the base end portion 31, the corner joining region 90 is defined by the outer end edge 31 a and the outer edge 31 b of the base end portion 31 and the outer edge 70 a of the boundary side joining region 70, and has a substantially triangular shape. . The corner bonding area 90 has a bonding strength lower than that of the boundary side bonding area 70. In the present embodiment, an adhesive such as a hot melt adhesive is applied to the entire bonding area 38, and the bonding portion 75 is formed only by the fusing means in the boundary-side bonding area 70, thereby the corner bonding area 90. The bonding strength is lower than that of the boundary-side bonding area 70. In addition, the joint part 75 may be formed in both the boundary side joint area 70 and the corner part joint area 90, and the joint part 75 may be densely arranged so that the joint strength is increased in the boundary side joint area 70.

図８は、着用者に対して、おむつ１０を装着するときの操作手順を示したものである。まず、図８（ａ）に示すとおり、一対の連結部材３０を展開した状態で、おむつ１０の後ウエスト域１２を着用者の背側に対向させるようにして配置する。かかる展開状態において、連結部材３０の自由部３２は、横方向Ｘ外側へ引っ張られ、その一部は後ウエスト域１２の第３係止部５５に係止される。次に、図８（ｂ）に示すとおり、一対の連結部材３０を横方向Ｘの外側へ引っ張って第２シート３６が着用者の身体と対向するようにして着用者の腰部６９に巻き付け、一方の連結部材６３の第１係止部３４を他方の連結部材６４に係止する。次に、図８（ｃ），（ｄ）に示すとおり、前ウエスト域１１又はファスニングテープ４０を引き寄せて、前ウエスト域１１を着用者の腹側に対向させるようにして配置し、前ウエスト域１１の中央係止部２７と、ファスニングテープ４０の第２係止部４４を連結部材３０に係止する。   FIG. 8 shows an operation procedure when the diaper 10 is worn on the wearer. First, as shown to Fig.8 (a), it arrange | positions so that the back waist area 12 of the diaper 10 may be made to oppose a wearer's back side in the state which expand | deployed a pair of connection member 30. FIG. In such an unfolded state, the free portion 32 of the connecting member 30 is pulled outward in the lateral direction X, and a part thereof is locked to the third locking portion 55 of the rear waist region 12. Next, as shown in FIG. 8B, the pair of connecting members 30 are pulled outward in the lateral direction X so that the second sheet 36 faces the wearer's body and is wound around the waist 69 of the wearer. The first locking portion 34 of the connecting member 63 is locked to the other connecting member 64. Next, as shown in FIGS. 8 (c) and 8 (d), the front waist region 11 or the fastening tape 40 is drawn and arranged so that the front waist region 11 faces the abdomen of the wearer, and the front waist region 11 and the second locking portion 44 of the fastening tape 40 are locked to the connecting member 30.

おむつ１０の着用操作では、連結部材３０を横方向Ｘの外側へ引っ張って着用者の腰部６９に巻き付けるため、境界側接合域７０に横方向Ｘへ剥離しようとする引っ張り力が作用し、連結部材３０を巻き付けた後、前ウエスト域１１を身体にフィットさせる際には境界側接合域７０に縦方向Ｙへ剥離しようとする引っ張り力が作用する。また、着用中において連結部材３０を掴んで、おむつ１０を引き上げる場合には、境界側接合域７０に縦方向Ｙへ引っ張る力が作用する。また、一対の連結部材３０を腰部６９に掛け回して互いに連結したときに、おむつ１０を適正な位置に移動させる場合には、連結部材３０を掴んで上方又は斜め上方へ引き上げる操作が必要になる。すなわち、基端部３１の境界側接合域７０には、ｉ）横方向Ｘの内側から外側へ引っ張る力Ｆ１と、ｉｉ）レッグ開口１７側からウエスト開口１６側へ縦方向Ｙに引っ張る力Ｆ２と、ｉｉｉ）境界線３１ｃに直交する方向に引っ張る力Ｆ３とが強く作用する。通常、ある方向へ引っ張り力が作用する場合、接合部が力の作用方向に延びているものよりも、力の作用方向に対して直交／交差している方が、剥離強度が高くなる。   In the operation of wearing the diaper 10, the connecting member 30 is pulled outwardly in the lateral direction X and wound around the waist portion 69 of the wearer, so that a pulling force to peel off in the lateral direction X acts on the boundary side joining region 70. After winding 30, when the front waist region 11 is fitted to the body, a pulling force that attempts to peel in the longitudinal direction Y acts on the boundary side joining region 70. Further, when the diaper 10 is pulled up by grasping the connecting member 30 during wearing, a force pulling in the longitudinal direction Y acts on the boundary side joining area 70. Further, when the diaper 10 is moved to an appropriate position when the pair of connecting members 30 are hung around the waist portion 69 and connected to each other, an operation of grasping the connecting member 30 and pulling it upward or obliquely upward is required. . That is, in the boundary-side joining region 70 of the base end portion 31, i) a force F1 that pulls from the inside in the lateral direction X to the outside, and ii) a force F2 that pulls in the longitudinal direction Y from the leg opening 17 side to the waist opening 16 side Iii) Force F3 pulling in a direction perpendicular to the boundary line 31c acts strongly. Usually, when a tensile force acts in a certain direction, the peel strength is higher when the joint is orthogonal / intersect to the force acting direction than when the joint extends in the force acting direction.

本実施形態のおむつ１０では、接合部７５が互いに異なる方向へ延びる縦断接合部８１と横断接合部８２とを有しているため、接合部７５に横方向Ｘへの力Ｆ１が作用した場合には、これと交差する方向へ延在する縦断接合部８１によって接合部７５が剥離したり、破れが生じたりすることを防止することができ、縦方向Ｙへの力Ｆ２が作用した場合には、これと交差する方向へ延在する横断接合部８２によって剥離や破れが生じるのを防止することができる。さらに、第１及び第２方向は、それぞれ、境界線３１ｃが延びる方向（長さ方向Ｋ）と交差する方向であるため、直交する方向への力Ｆ３に対しても剥離し難く、該長さ方向に沿って剥離が生じるのを防止することができる。   In the diaper 10 of the present embodiment, the joint portion 75 includes the longitudinal joint portion 81 and the transverse joint portion 82 that extend in different directions. Therefore, when the force F1 in the lateral direction X acts on the joint portion 75. Can prevent the joint 75 from being peeled off or torn by the longitudinal joint 81 extending in the direction intersecting with this, and when the force F2 in the longitudinal direction Y is applied. Further, it is possible to prevent the peeling and tearing from occurring due to the transverse joint portion 82 extending in the direction intersecting with this. Furthermore, since the first and second directions are directions that intersect the direction (length direction K) in which the boundary line 31c extends, it is difficult to peel off even with respect to the force F3 in the orthogonal direction. It is possible to prevent peeling along the direction.

なお、接合部７５は、中間部８３を有していない形状（例えば、縦断接合部８１と横断接合部８２とがほぼ垂直に交わる形状）であってもよいが、湾曲状の中間部８３を有することにより、境界線３１ｃに直交する方向への力Ｆ３に対して剥離強度を高めることができる。中間部８３が直線状である場合や、縦断接合部８１と横断接合部８２とが交角を成すように交差する場合には、角となる部位に引張応力が集中しやすくなるが、湾曲状とすることでかかる事態をなくして破れをより効果的に防止することができる。長さ方向Ｋと直交する方向における剥離強度は、少なくとも１０Ｎ／２５ｍｍであり、１５Ｎ／２５ｍｍ以上の剥離強度を有することが好ましい。また、連結部材３０の境界側接合域７０全体の最大引張強度が６０Ｎ以上であることが好ましい。境界側接合域７０において、各シートが接着剤のみで接合されている場合には、剥離が生じた際に、粘着性のある接着剤が露出して衣類が汚れたり、硬化した接着剤が肌に触れて刺激を与えたりするおそれがあるが、接合部７５が形成されることによって、かかる事態を防止することができる。   The joining portion 75 may have a shape that does not have the intermediate portion 83 (for example, a shape in which the longitudinal joining portion 81 and the transverse joining portion 82 intersect substantially perpendicularly). By having, peeling strength can be increased with respect to force F3 in a direction orthogonal to the boundary line 31c. When the intermediate part 83 is straight or when the longitudinal joint 81 and the transverse joint 82 intersect at an angle of intersection, tensile stress tends to concentrate at the corner, but the curved shape By doing so, it is possible to eliminate such a situation and prevent tearing more effectively. The peel strength in the direction orthogonal to the length direction K is at least 10 N / 25 mm, and preferably has a peel strength of 15 N / 25 mm or more. Moreover, it is preferable that the maximum tensile strength of the whole boundary side joining area | region 70 of the connection member 30 is 60 N or more. In the boundary-side joining area 70, when the sheets are joined only with an adhesive, when peeling occurs, the adhesive is exposed and the clothes are soiled or the cured adhesive is exposed to the skin. However, such a situation can be prevented by forming the joint portion 75.

また、既述のとおり、境界側接合域７０の内外端部７４，７３において縦断接合部８１と横断接合部８２の寸法Ｍ１，Ｍ２の割合が異なるようにしたり、縦断接合部８１と横断接合部８２の幅寸法をそれぞれ異なるようにしたりすることにより、所要方向における剥離強度を高めてもよい。例えば、外端部７３では縦断接合部８１の総面積を横断接合部８２の総面積よりも大きくて、横方向Ｘに対する剥離強度を縦方向Ｙにおけるそれよりも高くし、内端部７４では横断接合部８２の総面積を縦断接合部８１よりも大きくして、縦方向Ｙに対する剥離強度を横方向Ｘにおけるそれよりも高くすることができる。このように、内外端部７４，７３において、縦断接合部８１と横断接合部８２との総面積を変えることにより、必要な方向における剥離強度を高めながら、境界側接合域７０における接合面積を比較的に小さくし、境界側接合域７０において柔軟性が損なわれるのを抑制することができる。境界側接合域７０の外端部７３における横方向Ｘに対する剥離強度、及び内端部７４における縦方向Ｙに対する剥離強度は、それぞれ、少なくとも１０Ｎ／２５ｍｍ以上であることが好ましい。   Further, as described above, the ratios of the dimensions M1 and M2 of the longitudinal joining portion 81 and the transverse joining portion 82 in the inner and outer end portions 74 and 73 of the boundary side joining region 70 are different, or the longitudinal joining portion 81 and the transverse joining portion are different. The peel strength in the required direction may be increased by making the width dimensions of 82 different. For example, at the outer end 73, the total area of the longitudinal joining portion 81 is larger than the total area of the transverse joining portion 82, the peel strength in the lateral direction X is higher than that in the longitudinal direction Y, and the inner end 74 is transverse. The total area of the joining portion 82 can be made larger than that of the longitudinal joining portion 81, and the peel strength in the longitudinal direction Y can be made higher than that in the transverse direction X. In this way, in the inner and outer end portions 74 and 73, by changing the total area of the longitudinal joining portion 81 and the transverse joining portion 82, the joining area in the boundary side joining region 70 is compared while increasing the peel strength in the necessary direction. Thus, it is possible to suppress the flexibility from being lost in the boundary-side joining area 70. The peel strength in the lateral direction X at the outer end 73 of the boundary side joining area 70 and the peel strength in the longitudinal direction Y at the inner end 74 are each preferably at least 10 N / 25 mm or more.

なお、図示していないが、連結部材３０の基端部３１は、補強シートを介しておむつ本体１４に固定される構成であってもよい。基端部３１とおむつ本体１４の表面（バックシート２２によって形成される表面）との界面の接合強度が高い場合であっても、おむつ本体１４の表面を形成するシート強度が弱い場合には、おむつ本体１４に破れが生じてしまうが、補強シートを介在させることによって、おむつ本体１４全体の剛性を高めることなく、連結部材３０との接合域３８において、おむつ本体１４の外面（表面）を部分的に剛性の高い状態にすることができ、連結部材３０とおむつ本体１４との接合強度（取付強度）を高めることができる。   In addition, although not shown in figure, the structure fixed to the diaper main body 14 via the reinforcement sheet may be sufficient as the base end part 31 of the connection member 30. FIG. Even when the bonding strength at the interface between the base end portion 31 and the surface of the diaper main body 14 (the surface formed by the back sheet 22) is high, if the sheet strength forming the surface of the diaper main body 14 is weak, Although the diaper main body 14 is torn, the outer surface (surface) of the diaper main body 14 is partially formed in the joining region 38 with the connecting member 30 without increasing the rigidity of the whole diaper main body 14 by interposing a reinforcing sheet. Therefore, it is possible to achieve a highly rigid state, and it is possible to increase the bonding strength (mounting strength) between the connecting member 30 and the diaper main body 14.

図９は、実施形態に示したおむつ１０の接合域３８の変形例１を示す。変形例１におけるおむつ１０では、長さ方向Ｋにおいて、接合部７５が連続的に複数配置されている。接合部７５が内端部７４から外端部７３に亘って連続的に配置されていても、縦方向Ｙ及び横方向Ｘに作用する力に対して境界側接合域７０における剥離やおむつ１０の破れを効果的に防止し得る。 <Modification 1>
FIG. 9 shows a first modification of the joining region 38 of the diaper 10 shown in the embodiment. In the diaper 10 according to the first modification, a plurality of joining portions 75 are continuously arranged in the length direction K. Even if the joining portion 75 is continuously arranged from the inner end portion 74 to the outer end portion 73, the peeling in the boundary side joining region 70 and the diaper 10 against the force acting in the longitudinal direction Y and the transverse direction X are performed. It can effectively prevent tearing.

＜変形例２＞
図１０及び図１１は、実施形態に示したおむつ１０の接合域３８の変形例２を示す。変形例２におけるおむつ１０の境界側接合域７０において、接合部７５は、第１方向へ延びる縦断接合部（第１接合部）８１と、第２方向へ延びる横断接合部（第２接合部）８２とを有しており、縦中心線Ｐに対し、第１方向の傾斜角度は約０度、第２方向の傾斜角度αは約１２０度である。接合部７５において、横断接合部８２はクロッチ域１３側に位置する第１横断接合部８２ａと、ウエスト開口１６側に位置する第２横断接合部８２ｂとを有し、第１横断接合部８２ａは、縦断接合部８１の下端から第２方向へ延びている。縦断接合部８１は、第２横断接合部８２ｂよりも縦方向Ｙ外側へ延出している。接合部７５は、長さ方向Ｋへ連続的又は不連続的に複数配置され、本変形例では不連続的に配置されている。 <Modification 2>
FIG.10 and FIG.11 shows the modification 2 of the junction area 38 of the diaper 10 shown to embodiment. In the boundary-side joining region 70 of the diaper 10 according to Modification 2, the joining portion 75 includes a longitudinal joining portion (first joining portion) 81 extending in the first direction and a transverse joining portion (second joining portion) extending in the second direction. 82, the inclination angle in the first direction is about 0 degree and the inclination angle α in the second direction is about 120 degrees with respect to the longitudinal center line P. In the joint portion 75, the transverse joint portion 82 includes a first transverse joint portion 82a located on the crotch region 13 side and a second transverse joint portion 82b located on the waist opening 16 side, and the first transverse joint portion 82a is , Extending in the second direction from the lower end of the longitudinal joint 81. The longitudinal joint 81 extends outward in the longitudinal direction Y from the second transverse joint 82b. A plurality of the joint portions 75 are continuously or discontinuously arranged in the length direction K, and are discontinuously arranged in this modification.

接合部７５において、横断接合部８２の長さ寸法（第２方向における寸法）Ｓ２は、縦断接合部８１の長さ寸法（第１方向における寸法）Ｓ１よりも大きいことが好ましい。また、縦断接合部８１の幅寸法（第１方向と直交する方向における寸法）Ｔ１は、横断接合部８２の幅寸法（第２方向と直交する方向における寸法）Ｔ２よりも大きいことが好ましい。なお、各接合部８１，８２の長さ寸法Ｓ１，Ｓ２及び幅寸法Ｔ１，Ｔ２は適宜設定することができ、例えば、境界側接合域７０の内外端部７４，７３において、縦断接合部８１の総面積と横断接合部８２の総面積とが互いに異なるようにしてもよい。   In the joint 75, the length dimension (dimension in the second direction) S2 of the transverse joint part 82 is preferably larger than the length dimension (dimension in the first direction) S1 of the longitudinal joint 81. Moreover, it is preferable that the width dimension (dimension in the direction orthogonal to the first direction) T1 of the longitudinal joint 81 is larger than the width dimension (dimension in the direction orthogonal to the second direction) T2 of the transverse junction 82. The length dimensions S1 and S2 and the width dimensions T1 and T2 of the joint portions 81 and 82 can be appropriately set. For example, at the inner and outer end portions 74 and 73 of the boundary side joint region 70, The total area and the total area of the transverse junction 82 may be different from each other.

連結部材３０を掴んで後ウエスト域１２を横方向Ｘへ拡げながら引き上げる際には、一対の連結部材３０を斜め上方へ互いに離間するように引き上げるが、本変形例のように、横断接合部８２が横方向Ｘに対して傾斜する場合には、この引き上げ方向と横断接合部８２の延在方向（第２方向）とが垂直に近い角度となり、境界線３１ｃにおける剥離や破れを効果的に防止し得る。また、境界側接合域７０には、ウエスト弾性体６１の収縮力によってウエスト周り方向（横方向Ｘ）へ引張力が作用するが、これと垂直又は垂直に近い角度で交差する縦断接合部８１が接合ライン１８の全域に配置されているので、このような横方向Ｘへの引張力に対する剥離強度を高めることができる。また、横断接合部８２は、横方向Ｘに対して傾斜しているが、縦断接合部８１に比して長さ寸法が大きく、横方向Ｘにおける寸法が比較的に長いものとなっており、縦方向Ｙに作用する力Ｆ２に対する剥離強度も高い。   When grasping the connecting member 30 and pulling up the rear waist region 12 while expanding it in the lateral direction X, the pair of connecting members 30 are lifted diagonally upward away from each other. Is inclined with respect to the transverse direction X, the pulling direction and the extending direction (second direction) of the transverse joining portion 82 are at an angle close to perpendicular, and effectively prevent peeling and tearing at the boundary line 31c. Can do. Further, a tensile force acts on the boundary side joining region 70 in the direction around the waist (lateral direction X) due to the contraction force of the waist elastic body 61, but there is a longitudinal joining portion 81 that intersects with this at an angle that is perpendicular or nearly perpendicular. Since it is arrange | positioned in the whole region of the joining line 18, the peeling strength with respect to the tensile force to such a horizontal direction X can be raised. In addition, the transverse joining portion 82 is inclined with respect to the lateral direction X, but the length dimension is larger than that of the longitudinal joining portion 81, and the dimension in the transverse direction X is relatively long.

図１２及び図１３は、実施形態に示したおむつ１０の接合域３８の変形例３を示す。変形例３におけるおむつ１０の境界側接合域７０は、第１方向へ延びる縦断接合部（第１接合部）８１と、第２方向へ延びる横断接合部（第２接合部）８２とを有しており、縦断接合部８１と横断接合部８２とは、それぞれ、長さ方向Ｋへ複数配置されている。 <Modification 3>
12 and 13 show a third modification of the joining region 38 of the diaper 10 shown in the embodiment. The boundary-side joining area 70 of the diaper 10 in Modification 3 includes a longitudinal joining part (first joining part) 81 extending in the first direction and a transverse joining part (second joining part) 82 extending in the second direction. A plurality of the longitudinal joints 81 and the transverse joints 82 are arranged in the length direction K, respectively.

図１３（ａ）を参照すると、境界側接合域７０の外端部７３では、隣り合う縦断接合部８１の離間距離（隣り合う縦断接合部８１の間の非接合部７６の距離）Ｒ１が、隣り合う横断接合部８２の離間距離（隣り合う横断接合部８２の間の非接合部７６の距離）Ｒ２よりも小さい。図１３（ｂ）を参照すると、境界側接合域７０の内端部７４では、隣り合う縦断接合部８１の離間距離Ｒ１が、隣り合う横断接合部８２の離間距離Ｒ２よりも大きい。図１３（ｃ）を参照すると、境界側接合域７０において、内外端部７４，７３の間に位置する中間部８０では、縦断接合部８１の離間距離Ｒ１と横断接合部８２の離間距離Ｒ２とがほぼ等しい。なお、中間部８０において、図示例の縦断接合部８１と横断接合部８２とは、連続するように一部が重なっているが、互いに離間する構成であってもよい。境界側接合域７０の内外端部７４，７３及び中間部８０における、縦断接合部８１の離間距離Ｒ１の相関関係は、内端部７４≧中間部８０＞外端部７３であり、横断接合部８２の離間距離Ｒ２の相関関係は、外端部７３≧中間部８０＞内端部７４であることが好ましい。   Referring to FIG. 13A, in the outer end portion 73 of the boundary-side joining region 70, the separation distance between adjacent longitudinal joining portions 81 (distance between the non-joining portions 76 between the adjacent longitudinal joining portions 81) R1 is The distance between adjacent transverse joint portions 82 (distance between non-joint portions 76 between adjacent transverse joint portions 82) R2 is smaller. Referring to FIG. 13B, at the inner end 74 of the boundary side joining area 70, the separation distance R <b> 1 between the adjacent longitudinal joining parts 81 is larger than the separation distance R <b> 2 between the adjacent transverse joining parts 82. Referring to FIG. 13 (c), in the boundary side joining area 70, in the intermediate part 80 located between the inner and outer end parts 74, 73, the separation distance R 1 of the longitudinal joining part 81 and the separation distance R 2 of the transverse joining part 82. Are almost equal. In the intermediate portion 80, the longitudinally joined portion 81 and the transversely joined portion 82 in the illustrated example are partially overlapped so as to be continuous, but may be separated from each other. In the inner and outer end portions 74 and 73 and the middle portion 80 of the boundary side joining region 70, the correlation of the separation distance R1 of the longitudinally joined portion 81 is inner end portion 74 ≧ intermediate portion 80> outer end portion 73. The correlation between the separation distances R <b> 2 of 82 is preferably such that the outer end portion 73 ≧ the intermediate portion 80> the inner end portion 74.

境界側接合域７０は、その長さ寸法Ｌ３及び又は面積がほぼ３等分になるように区分されていてもよいが、中間部８０はオプションであって、内外端部７４，７３の２つに区分されていてもよい。本実施形態においては、外端部７３と内端部７４とは、ほぼ同等の長さ寸法及び面積を有するものであって、例えば、それぞれ、境界側接合域７０の長さ寸法（境界線３１ｃの長さ寸法）Ｌ３の約２５〜５０％の大きさ及び／又は、その全体面積のうちの約２０〜５０％の面積を有する。したがって、境界側接合域７０は、縦断接合部８１が密に配置される外端部７３と、横断接合部８２が密に配置される内端部７４との２つに区分されてもよいし、中間部８０を含めて３つに区分されていてもよい。３つに区分される場合には、境界側接合域７０がその長さ寸法Ｌ３において均等に区分されてもよいし、中間部８０が内外端部７４，７３よりも長さ寸法が小さい等、同一の長さ寸法となるように均等に区分されていなくてもよい。なお、図示していないが、外端部７３では縦断接合部８１のみを配置し、内端部７４では横断接合部８２のみを配置する構成であってもよい。かかる場合、外端部７３及び内端部７４のそれぞれにおいて、縦断接合部８１及び横断接合部８２のそれぞれが少なくとも一つ存在していればよい。   The boundary side joining area 70 may be divided so that the length dimension L3 and / or the area thereof is approximately divided into three equal parts, but the intermediate part 80 is optional and includes two of the inner and outer end parts 74 and 73. It may be divided into. In the present embodiment, the outer end portion 73 and the inner end portion 74 have substantially the same length dimension and area. For example, the length dimension (the boundary line 31c) The size of L3 is about 25 to 50% of L3 and / or about 20 to 50% of the total area. Therefore, the boundary-side joining area 70 may be divided into two parts, that is, an outer end part 73 in which the longitudinal joining part 81 is densely arranged and an inner end part 74 in which the transverse joining part 82 is densely arranged. The intermediate portion 80 may be divided into three. In the case of being divided into three, the boundary-side joining area 70 may be equally divided in the length dimension L3, the intermediate part 80 is smaller in length than the inner and outer end parts 74 and 73, etc. It does not need to be equally divided so that it may become the same length dimension. In addition, although not shown in figure, the structure which arrange | positions only the vertical junction part 81 in the outer end part 73, and arrange | positions only the cross junction part 82 in the inner end part 74 may be sufficient. In such a case, at least one of the longitudinal joining portion 81 and the transverse joining portion 82 may be present in each of the outer end portion 73 and the inner end portion 74.

このように、外端部７３では、横断接合部８２に比して縦断接合部８１を密に配置し、内端部７４では、縦断接合部８１に比して横断接合部８２を密に配置することで、内外端部７４，７３に強く作用する力の方向に適した剥離強度を確保することができるとともに、内外端部７４，７３における接合面積を比較的に小さくして境界側接合域７０全体の剛性が比較的に高くなるのを防止することができる。   Thus, the longitudinal joint 81 is densely arranged at the outer end 73 as compared with the transverse joint 82, and the transverse joint 82 is densely arranged at the inner end 74 as compared with the longitudinal joint 81. By doing so, it is possible to ensure the peel strength suitable for the direction of the force that acts strongly on the inner and outer end portions 74 and 73, and to relatively reduce the bonding area at the inner and outer end portions 74 and 73, thereby making the boundary side bonding area. It is possible to prevent the rigidity of the entire 70 from becoming relatively high.
