胴周り弾性体21(21a,21b)は、上述したように、外装シート10の腹側部材11及び背側部材12の幅方向(左右方向、X方向)に延在し、パンツ型おむつ1の腰部4(4a,4b)から左脚開口部13及び右脚開口部14にかけて配置された複数の糸状の弾性部材から構成されている。ここで、胴周り弾性体21(21a,21b)は、パンツ型おむつ1の腰部4(4a,4b)側から左右の脚開口部13、14側へ向かうにつれて、徐々にその締め付け力が弱くなるように形成されている。 Next, the detailed configuration of the outer periphery of theexterior sheet 10 and the waist elastic body 21 (21a, 21b) provided around the waist will be described.
As described above, the waistline elastic body 21 (21a, 21b) extends in the width direction (left-right direction, X direction) of theabdomen side member 11 and the back side member 12 of the exterior sheet 10, and the pants-type diaper 1 It is composed of a plurality of thread-like elastic members arranged from the waist 4 (4a, 4b) to the left leg opening 13 and the right leg opening 14. Here, the tightening force of the waistline elastic body 21 (21a, 21b) gradually weakens from the waist 4 (4a, 4b) side of the pant-type diaper 1 toward the left and right leg openings 13, 14 side. It is formed as follows.
胴周り弾性体21(21a,21b)は、上述したように、外装シート10の腹側部材11及び背側部材12の幅方向(左右方向、X方向)に延在し、パンツ型おむつ1の腰部4(4a,4b)から左脚開口部13及び右脚開口部14にかけて配置された複数の糸状の弾性部材から構成されている。ここで、胴周り弾性体21(21a,21b)は、パンツ型おむつ1の腰部4(4a,4b)側から左右の脚開口部13、14側へ向かうにつれて、徐々にその締め付け力が弱くなるように形成されている。 Next, the detailed configuration of the outer periphery of the
As described above, the waistline elastic body 21 (21a, 21b) extends in the width direction (left-right direction, X direction) of the
本実施形態では、胴周り弾性体21(21a,21b)を構成する弾性部材のうち、左右の脚開口部13、14側(下端側)に配置される弾性部材は、その弾性部材よりも腰部4(4a,4b)側(上端側)に配置される弾性部材に比して張力(収縮力)が弱くなるよう設けられている。
具体的には、胴周り弾性体21(21a,21b)は、弾性部材が外面シート10a及び内面シート10b間に伸長させて接合される場合に、腰部4(4a,4b)から左右の脚開口部13、14側に向かって配置されるにつれて徐々に弾性部材の伸長倍率を低くするように形成されている。これにより、本実施形態のパンツ型おむつ1は、腰部4(4a,4b)側から左右の開口部13、14側にかけて胴周りの締め付け力が徐々に弱くなり、着用者の腹部及び臀部にフィットさせることができる。また、パンツ型おむつ1がずれ落ちてしまうのを抑制することができる。 In the present embodiment, among the elastic members constituting the waist elastic body 21 (21a, 21b), the elastic members disposed on the left and right leg openings 13, 14 side (lower end side) are lower than the elastic members. 4 (4a, 4b) is provided so that tension (contraction force) is weaker than that of the elastic member arranged on the side (upper end side).
Specifically, the waist elastic body 21 (21a, 21b) is configured to open the left and right leg openings from the waist 4 (4a, 4b) when the elastic member is extended and joined between theouter sheet 10a and the inner sheet 10b. The elastic member is formed so as to gradually reduce the expansion ratio as it is disposed toward the portions 13 and 14. Thereby, the underpants type diaper 1 of this embodiment gradually weakens the tightening force around the waist from the waist 4 (4a, 4b) side to the left and right openings 13, 14 and fits the wearer's abdomen and buttocks. Can be made. Moreover, it can suppress that the underpants type diaper 1 slips down.
具体的には、胴周り弾性体21(21a,21b)は、弾性部材が外面シート10a及び内面シート10b間に伸長させて接合される場合に、腰部4(4a,4b)から左右の脚開口部13、14側に向かって配置されるにつれて徐々に弾性部材の伸長倍率を低くするように形成されている。これにより、本実施形態のパンツ型おむつ1は、腰部4(4a,4b)側から左右の開口部13、14側にかけて胴周りの締め付け力が徐々に弱くなり、着用者の腹部及び臀部にフィットさせることができる。また、パンツ型おむつ1がずれ落ちてしまうのを抑制することができる。 In the present embodiment, among the elastic members constituting the waist elastic body 21 (21a, 21b), the elastic members disposed on the left and
Specifically, the waist elastic body 21 (21a, 21b) is configured to open the left and right leg openings from the waist 4 (4a, 4b) when the elastic member is extended and joined between the
また、外装シート10の胴周り(胴周り弾性体21)には、胴周り弾性体21(21a,21b)の締め付け力が及ばない非弾性部P(図2中の一点鎖線内)が設けられている。この非弾性部Pは、外装シート10の幅方向(左右方向、X方向)の中心線C1に対して線対称であって、腰部4(4a,4b)と左右の脚開口部13、14との間に設けられ、腰部4(4a,4b)側から左右の脚開口部13、14側に向かうにつれて、その幅寸法(左右幅)が徐々に大きくなるように形成されている。これによっても、パンツ型おむつ1は、胴周り弾性体21(21a,21b)の腰部4(4a,4b)側から左右の脚開口部13、14側へ向かうにつれて、徐々にその締め付け力を弱くすることができる。
ここで、上述したように、胴周り弾性体21(21a,21b)は、腰部4(4a,4b)側から左右の脚開口部13、14側へ向かうにつれて、徐々にその締め付け力を弱くしているが、その締め付け力を変更する範囲は、腹側では着用者のウエストの下部から恥骨上部に対応する位置、背側では着用者のウエストの下部から坐骨に対応する位置であることが好ましい。
また、胴周り弾性体21(21a,21b)の締め付け力は、上述の効果をより効果的に奏するために、最も弱い部位(股部5側)が、最も強い部位(腰部4側)の60~95%であることが好ましい。
なお、パンツ型おむつ1は、腹側部材11と背側部材12とで胴周り弾性体21(21a,21b)の弾性部材の張力や、非弾性部Pの幅寸法(左右幅)を変更したりして、胴周り弾性体21(21a,21b)による締め付け力を前後(腹側と背側)で変更するようにしてもよい。具体的には、腹側部材11の胴周り弾性体21aの弾性部材の張力を、背側部材12の胴周り弾性体21bの弾性部材に比して強くしたり、腹側部材11の非弾性部Pの幅寸法(左右幅)を、背側部材12の非弾性部Pに比して狭くしたりすることで、胴周り弾性体21の腹側の締め付け力を背側に比して強くすることができる。これにより、パンツ型おむつ1を、着用者の腹側と背側とのそれぞれの体型に沿わせることができ、着用時のフィット性をより向上させることができる。 In addition, a non-elastic portion P (inside the one-dot chain line in FIG. 2) where the tightening force of the waist elastic body 21 (21a, 21b) does not reach is provided around the waist of the exterior sheet 10 (the waist elastic body 21). ing. The inelastic portion P is line symmetric with respect to the center line C1 in the width direction (left and right direction, X direction) of theexterior sheet 10, and the waist portion 4 (4a, 4b) and the left and right leg openings 13, 14 The width dimension (left-right width) is gradually increased from the waist 4 (4a, 4b) side toward the left and right leg openings 13, 14 side. Also by this, the underpants type diaper 1 gradually weakens its tightening force as it goes from the waist 4 (4a, 4b) side of the waist elastic body 21 (21a, 21b) to the left and right leg openings 13, 14 side. can do.
Here, as described above, the waist elastic body 21 (21a, 21b) gradually weakens its tightening force from the waist 4 (4a, 4b) side toward the left and right leg openings 13, 14 side. However, the range in which the tightening force is changed is preferably a position corresponding to the upper pubic bone from the lower part of the wearer's waist on the abdominal side, and a position corresponding to the sciatic bone from the lower part of the wearer's waist on the back side. .
Further, the tightening force of the waist elastic body 21 (21a, 21b) is 60, which is the weakest part (thecrotch 5 side) and the strongest part (the waist part 4 side) in order to achieve the above-described effect more effectively. It is preferable to be -95%.
In the pants-type diaper 1, the abdominal member 11 and the back member 12 change the tension of the elastic member 21 (21a, 21b) and the width dimension (left-right width) of the non-elastic part P. Alternatively, the tightening force by the waist elastic body 21 (21a, 21b) may be changed back and forth (abdominal side and back side). Specifically, the tension of the elastic member of the waist elastic member 21a of the abdominal member 11 is made stronger than the elastic member of the waist elastic member 21b of the back member 12, or the elasticity of the belly member 11 is inelastic. By narrowing the width dimension (left-right width) of the part P compared to the non-elastic part P of the back side member 12, the tightening force on the belly side of the waist elastic body 21 is stronger than the back side. can do. Thereby, the underpants type diaper 1 can be made to follow each body type of a wearer's abdominal side and back side, and the fit property at the time of wear can be improved more.
ここで、上述したように、胴周り弾性体21(21a,21b)は、腰部4(4a,4b)側から左右の脚開口部13、14側へ向かうにつれて、徐々にその締め付け力を弱くしているが、その締め付け力を変更する範囲は、腹側では着用者のウエストの下部から恥骨上部に対応する位置、背側では着用者のウエストの下部から坐骨に対応する位置であることが好ましい。
また、胴周り弾性体21(21a,21b)の締め付け力は、上述の効果をより効果的に奏するために、最も弱い部位(股部5側)が、最も強い部位(腰部4側)の60~95%であることが好ましい。
なお、パンツ型おむつ1は、腹側部材11と背側部材12とで胴周り弾性体21(21a,21b)の弾性部材の張力や、非弾性部Pの幅寸法(左右幅)を変更したりして、胴周り弾性体21(21a,21b)による締め付け力を前後(腹側と背側)で変更するようにしてもよい。具体的には、腹側部材11の胴周り弾性体21aの弾性部材の張力を、背側部材12の胴周り弾性体21bの弾性部材に比して強くしたり、腹側部材11の非弾性部Pの幅寸法(左右幅)を、背側部材12の非弾性部Pに比して狭くしたりすることで、胴周り弾性体21の腹側の締め付け力を背側に比して強くすることができる。これにより、パンツ型おむつ1を、着用者の腹側と背側とのそれぞれの体型に沿わせることができ、着用時のフィット性をより向上させることができる。 In addition, a non-elastic portion P (inside the one-dot chain line in FIG. 2) where the tightening force of the waist elastic body 21 (21a, 21b) does not reach is provided around the waist of the exterior sheet 10 (the waist elastic body 21). ing. The inelastic portion P is line symmetric with respect to the center line C1 in the width direction (left and right direction, X direction) of the
Here, as described above, the waist elastic body 21 (21a, 21b) gradually weakens its tightening force from the waist 4 (4a, 4b) side toward the left and
Further, the tightening force of the waist elastic body 21 (21a, 21b) is 60, which is the weakest part (the
In the pants-
また、非弾性部Pは、外装シート10の腹側部材11及び背側部材12の胴回り弾性体21(21a,21b)が吸収部材30と重なる領域であって、吸収部材30の幅方向(左右方向、X方向)の両端縁(左右端縁)よりも内側に形成されている。この外装シート10の胴回り弾性体21(21a,21b)及び吸収部材30が重なる領域には、上述の胴周り弾性体21(21a,21b)の締め付け力を有する一部も形成されている。
ここで、非弾性部Pは、吸収部材30の幅方向の両端縁(左右端縁)よりも外側まで延在した場合、吸収部材30が着用者の身体から離れてしまい漏れなどの要因となるおそれがある。そのため、非弾性部Pは、上述のように、吸収部材30の幅方向の両端縁(左右端縁)よりも内側に形成される必要があり、その最大幅は、吸収部材30の幅寸法により制限され、吸収部材30の幅寸法(左右幅)よりも小さい幅にする必要がある。 The inelastic portion P is a region where the waist elastic members 21 (21a, 21b) of theabdominal member 11 and the back member 12 of the exterior sheet 10 overlap the absorbent member 30, and the width direction (left and right) of the absorbent member 30 Direction, X direction) is formed inside the both end edges (left and right end edges). In the region where the waistline elastic body 21 (21a, 21b) and the absorbing member 30 of the exterior sheet 10 overlap, a part having the tightening force of the above-described waistline elastic body 21 (21a, 21b) is also formed.
Here, when the non-elastic portion P extends to the outside of both end edges (left and right end edges) in the width direction of theabsorbent member 30, the absorbent member 30 is separated from the wearer's body and causes leakage and the like. There is a fear. Therefore, as described above, the non-elastic portion P needs to be formed inside the both end edges (left and right end edges) in the width direction of the absorbing member 30, and the maximum width depends on the width dimension of the absorbing member 30. The width is limited and needs to be smaller than the width dimension (left-right width) of the absorbing member 30.
ここで、非弾性部Pは、吸収部材30の幅方向の両端縁(左右端縁)よりも外側まで延在した場合、吸収部材30が着用者の身体から離れてしまい漏れなどの要因となるおそれがある。そのため、非弾性部Pは、上述のように、吸収部材30の幅方向の両端縁(左右端縁)よりも内側に形成される必要があり、その最大幅は、吸収部材30の幅寸法により制限され、吸収部材30の幅寸法(左右幅)よりも小さい幅にする必要がある。 The inelastic portion P is a region where the waist elastic members 21 (21a, 21b) of the
Here, when the non-elastic portion P extends to the outside of both end edges (left and right end edges) in the width direction of the
本実施形態では、非弾性部Pは、幅方向の寸法(左右幅)が、腰部4(4a,4b)側から左右の脚開口部13、14側に向かうにつれて徐々に大きくなり、左右の脚開口部13、14に近づいた位置で一定となるように、略三角形状と略矩形形状とを組み合わせた形状に形成される。そのため、胴周り弾性体21(21a,21b)は、外装シート10及び吸収部材30の重なる領域における幅方向の寸法(左右幅)が、腰部4(4a,4b)側から左右の開口部13、14側に向かうにつれて徐々に短くなり、非弾性部Pの幅方向の寸法(左右幅)が一定になったところで存在しなくなる。すなわち、胴周り弾性体21(21a,21b)は、外装シート10及び吸収部材30が重なる領域においては、非弾性部Pの略三角形状の外側に形成されている。
In the present embodiment, the inelastic portion P has a dimension in the width direction (left and right width) that gradually increases from the waist 4 (4a, 4b) side toward the left and right leg openings 13 and 14, and the left and right legs. It is formed in a shape combining a substantially triangular shape and a substantially rectangular shape so as to be constant at a position close to the openings 13 and 14. Therefore, the waist elastic body 21 (21a, 21b) has a widthwise dimension (left-right width) in a region where the exterior sheet 10 and the absorbing member 30 overlap, and the left and right openings 13 from the waist 4 (4a, 4b) side. The length gradually decreases toward the 14th side, and does not exist when the widthwise dimension (left-right width) of the inelastic part P becomes constant. That is, the waistline elastic body 21 (21a, 21b) is formed on the substantially triangular outer side of the non-elastic portion P in the region where the exterior sheet 10 and the absorbing member 30 overlap.
ここで、パンツ型おむつのずれ落ちを防止するためには、腰周り弾性体21を骨盤で最も幅方向に張り出している腸骨の上部に位置するようにしなくてはならないが、腸骨の位置を水平に締め付けると、呼吸や姿勢などによって最も寸法が変化する腹部を締め付け続けることになり、不快感が大きくなる場合があった。一方、締め付けを弱くするとずれ落ちが生じる場合があり、着用者によって異なる体型に合わせて最適の張力を設定することが難しかった。
このため、本発明のパンツ型おむつ1は、上述のように非弾性部Pを設けることによって、骨格のない腹部の水平方向の締め付けを抑え、骨盤に沿うように左右の腸骨上部から恥骨上部にかけて斜め方向に腹側の胴周り弾性体21aの張力が働くようにすることができる。また、背側においてもウエストからヒップにかけての身体の周長が徐々に大きくなることに対し、均等な張力で支えることができるように背側の胴周り弾性体21bの締め付けを調整することができる。これらにより、パンツ型おむつ1は、良好なフィット性を実現しつつ、ずれ落ちを抑制することができる。 Here, in order to prevent the pants-type diaper from slipping down, the waistelastic body 21 must be positioned at the upper part of the iliac projecting in the width direction on the pelvis. When tightening horizontally, the abdomen whose dimensions change the most depending on breathing and posture will continue to be tightened, which may increase discomfort. On the other hand, if the tightening is weakened, there is a case where a slip-off occurs, and it is difficult to set an optimum tension according to a different body shape depending on the wearer.
For this reason, the pants-type diaper 1 of the present invention suppresses the horizontal tightening of the abdomen without the skeleton by providing the inelastic part P as described above, and the upper pubic bone from the upper left and right iliac along the pelvis. Thus, the tension of the elastic body 21a on the ventral side in the oblique direction can be exerted. Also, on the back side, the circumference of the body from the waist to the hip gradually increases, and the tightening of the back waist elastic body 21b can be adjusted so that it can be supported with equal tension. . By these, the underpants type diaper 1 can suppress slipping off while realizing good fit.
このため、本発明のパンツ型おむつ1は、上述のように非弾性部Pを設けることによって、骨格のない腹部の水平方向の締め付けを抑え、骨盤に沿うように左右の腸骨上部から恥骨上部にかけて斜め方向に腹側の胴周り弾性体21aの張力が働くようにすることができる。また、背側においてもウエストからヒップにかけての身体の周長が徐々に大きくなることに対し、均等な張力で支えることができるように背側の胴周り弾性体21bの締め付けを調整することができる。これらにより、パンツ型おむつ1は、良好なフィット性を実現しつつ、ずれ落ちを抑制することができる。 Here, in order to prevent the pants-type diaper from slipping down, the waist
For this reason, the pants-
また、本実施形態では、非弾性部Pは、その上端部(腰部4a,4b側の部分)が、外装シート10及び吸収部材30の重なる領域からはみ出すように形成されている。
これは、一般的にパンツ型おむつの吸収部材は、尿などの***物を吸収するため、尿道口から肛門付近までを広くカバーする長さになっており、横になった時などでも尿などが流れ出ないよう、さらに余裕を持たせて長くしたものもある。しかし、長くしすぎると、腹部や背部に不快感を与えるため、通常は成人用の場合では、400~600mmの範囲の長さに形成されている。これに対し、パンツ型おむつやパッドホルダーの展開長(腹側部材11の腰部4aから背側部材12の腰部4bまでの長さ)は、吸収部材の長さよりさらに成人用で100~500mm程度長く形成されている。
ここで、非弾性部Pの上下方向の適正位置は、腹側ではウエストの下部から恥骨上部、背側ではウエストの下部から坐骨にあたる位置にかけて設けられるのが好ましく、吸収部材30の配置位置には制限されないため、必ずしも吸収部材と重ならず、本実施形態では、非弾性部Pの上端部が上述のようにはみ出している。 Moreover, in this embodiment, the non-elastic part P is formed so that the upper end part (part by the side of the waist | lumbar part 4a, 4b) protrudes from the area | region where the exterior sheet 10 and the absorption member 30 overlap.
This is because pants-type diaper absorbent members generally absorb urine and other excrement, so that they cover a wide area from the urethral orifice to the vicinity of the anus. Some of them have been made longer to keep them from flowing out. However, if it is too long, it gives discomfort to the abdomen and back, so in the case of an adult, the length is usually in the range of 400 to 600 mm. In contrast, the unfolded length of the pant-type diaper or pad holder (the length from thewaist 4a of the abdominal member 11 to the waist 4b of the dorsal member 12) is about 100 to 500 mm longer for adults than the length of the absorbent member. Is formed.
Here, the appropriate vertical position of the inelastic portion P is preferably provided from the lower waist to the upper pubic bone on the abdominal side, and from the lower waist to the sciatic bone on the back side. Since it is not restricted, it does not necessarily overlap with the absorbing member, and in this embodiment, the upper end portion of the inelastic portion P protrudes as described above.

However, if it is too long, it gives discomfort to the abdomen and back, so in the case of an adult, the length is usually in the range of 400 to 600 mm.

Here, the appropriate vertical position of the inelastic portion P is preferably provided from the lower waist to the upper pubic bone on the abdominal side, and from the lower waist to the sciatic bone on the back side. Since it is not restricted, it does not necessarily overlap with the absorbing member, and in this embodiment, the upper end portion of the inelastic portion P protrudes as described above.
非弾性部Pが、外装シート10及び吸収部材30が重なる領域に形成されることによって、外装シート10の胴周りにおける吸収部材30が重ならない領域には、胴周り弾性体21(21a,21b)が存在することとなる。これにより、パンツ型おむつ1は、液状体を吸収した吸収部材30の重みによって、着用者の身体からパンツ型おむつ1がずれ落ちてしまうのを抑制することができる。
また、胴周り弾性体21(21a,21b)の腰部4(4a,4b)側の一部が、外装シート10及び吸収部材30が重なる領域であって、非弾性部Pの略三角形状の外側に形成されていることによって、着用者の腰に対するパンツ型おむつ1の締め付けの向きを斜め上方に変化させることができる(図1の矢印A参照)。これにより、パンツ型おむつ1の胴周りが、腰部4の両側から股部5方向へ、弧を描くように曲線状に曲がるため、着用者のお腹周りを締め付けずに腸骨に沿い、パンツ型おむつ1の着用時のフィット性や、ずれ落ち抑制効果を更に向上させることができる。 By forming the non-elastic portion P in the region where theexterior sheet 10 and the absorbing member 30 overlap, the waistline elastic body 21 (21a, 21b) is provided in the region around the body of the exterior sheet 10 where the absorbent member 30 does not overlap. Will exist. Thereby, the underpants type diaper 1 can suppress that the underpants type diaper 1 slips off from a wearer's body by the weight of the absorbing member 30 that has absorbed the liquid material.
In addition, a part of the waistline 4 (4a, 4b) side of the waist elastic body 21 (21a, 21b) is a region where theexterior sheet 10 and the absorbing member 30 overlap, and the substantially elastic outer side of the inelastic part P The direction of tightening of the pants-type diaper 1 with respect to the wearer's waist can be changed obliquely upward (see arrow A in FIG. 1). As a result, the trunk circumference of the pant-type diaper 1 bends in a curved shape so as to draw an arc from both sides of the waist part 4 toward the crotch part 5. The fitting property at the time of wearing of the diaper 1 and the slip-off suppressing effect can be further improved.
また、胴周り弾性体21(21a,21b)の腰部4(4a,4b)側の一部が、外装シート10及び吸収部材30が重なる領域であって、非弾性部Pの略三角形状の外側に形成されていることによって、着用者の腰に対するパンツ型おむつ1の締め付けの向きを斜め上方に変化させることができる(図1の矢印A参照)。これにより、パンツ型おむつ1の胴周りが、腰部4の両側から股部5方向へ、弧を描くように曲線状に曲がるため、着用者のお腹周りを締め付けずに腸骨に沿い、パンツ型おむつ1の着用時のフィット性や、ずれ落ち抑制効果を更に向上させることができる。 By forming the non-elastic portion P in the region where the
In addition, a part of the waistline 4 (4a, 4b) side of the waist elastic body 21 (21a, 21b) is a region where the
更に、外装シート10に非弾性部Pが設けられることによって、上述のように幅方向(左右方向)における弾性部材の長さが、腰部4(4a,4b)側から左右の脚開口部13、14側に向かって配置されるにつれて徐々に短くなるので、パンツ側おむつ1の胴周りは、全体で見た場合、腰部4(4a,4b)側から左右の脚開口部13、14側に向かうにつれて徐々に胴周り弾性体21(21a,21b)の張力が存在しない領域が広くなる。そのため、パンツ型おむつ1は、着用者の腹部及び臀部に対する締め付けを身体の形状に合わせて、腰部4(4a,4b)側から左右の脚開口部13、14側に向かって弱くすることができ、これによっても、着用時のフィット性を向上させ、パンツ型おむつ1のずれ落ち抑制効果を向上させることができる。
Furthermore, by providing the non-elastic part P in the exterior sheet 10, the length of the elastic member in the width direction (left-right direction) as described above is such that the left and right leg openings 13, from the waist part 4 (4a, 4b) side, Since it gradually shortens as it is arranged toward the 14th side, the trunk circumference of the pants-side diaper 1 is viewed from the waist 4 (4a, 4b) side toward the left and right leg openings 13, 14 when viewed as a whole. As a result, the region where the tension of the waist elastic body 21 (21a, 21b) does not exist gradually increases. Therefore, the pants-type diaper 1 can be tightened to the wearer's abdomen and buttocks according to the shape of the body and weaken from the waist 4 (4a, 4b) side toward the left and right leg openings 13, 14 side. Also by this, the fitting property at the time of wear can be improved, and the slippage suppression effect of the pants-type diaper 1 can be improved.
なお、本実施形態では、非弾性部Pは、外装シート10の腰部4(4a,4b)から左右の脚開口部13、14までの間の胴周りにおいて、胴周り弾性体21(21a,21b)が形成されないようにして設けられているが、これに限定されるものでない。例えば、非弾性部Pは、胴周り弾性体21(21a,21b)を、外装シート10の腰部4(4a,4b)側から左右の脚開口部13、14側のほぼ全面に形成した上で、非弾性部Pに該当する領域においてのみ、胴周り弾性体21(21a,21b)を構成する弾性部材の弾性体としての機能、すなわち張力が発生しない状態にすることによって設けるようにしてもよい。

第2実施形態のパッドホルダー101は、吸収部材30が設けられていない点で、第1実施形態のパンツ型おむつ1と主に相違する。
パッドホルダー101は、尿や血液等の液状体を吸収するパッドやナプキンなどの吸収性物品を保持するパンツ型のホルダーである。パッドホルダー101は、その股部105に吸収性物品を配置した上で着用することによって、上述の第1実施形態のパンツ型おむつ1と同様の機能を実現することができる。
パッドホルダー101は、図4に示すように、腹側部材111、背側部材112、股部105、左脚開口部113、右脚開口部114、接合部115等から構成される外装シート110から形成されている。 Thepad holder 101 of the second embodiment is mainly different from the pant-type diaper 1 of the first embodiment in that the absorbent member 30 is not provided.
Thepad holder 101 is a pants-type holder that holds absorbent articles such as pads and napkins that absorb liquids such as urine and blood. The pad holder 101 can realize the same function as the pants-type diaper 1 of the first embodiment described above by wearing an absorbent article on the crotch portion 105 and wearing it.
As shown in FIG. 4, thepad holder 101 includes an exterior sheet 110 including a ventral member 111, a back member 112, a crotch portion 105, a left leg opening portion 113, a right leg opening portion 114, a joint portion 115, and the like. Is formed.
パッドホルダー101は、尿や血液等の液状体を吸収するパッドやナプキンなどの吸収性物品を保持するパンツ型のホルダーである。パッドホルダー101は、その股部105に吸収性物品を配置した上で着用することによって、上述の第1実施形態のパンツ型おむつ1と同様の機能を実現することができる。
パッドホルダー101は、図4に示すように、腹側部材111、背側部材112、股部105、左脚開口部113、右脚開口部114、接合部115等から構成される外装シート110から形成されている。 The
The
As shown in FIG. 4, the
腹側部材111及び背側部材112には、外装シート110の胴周り、すなわち外装シート110の腰部104(104a,104b)側から左脚開口部113及び右脚開口部114側にかけて胴周り弾性体121(121a,121b)が設けられている。
胴周り弾性体121(121a,121b)は、外装シート110の幅方向(左右方向、X方向)において、パッドホルダー101の腰部104(104a,104b)側から左右の脚開口部113、114側にかけて配置された複数の糸状の弾性部材から構成されている。ここで、胴周り弾性体121(121a,121b)を構成する弾性部材は、パッドホルダー101の腰部104(104a,104b)から左右の脚開口部113、114へ向かうにつれて、徐々に張力が弱くなるように形成されている。すなわち、左右の脚開口部113、114側(下端側)に配置される弾性部材は、その弾性部材よりも腰部104(104a,104b)側(上端側)に配置される弾性部材に比して張力が弱くなるよう設けられている。具体的には、胴周り弾性体121(121a,121b)は、弾性部材が外面シート110a及び内面シート110b間に伸長させて接合される場合に、腰部104(104a,104b)から左右の脚開口部113、114側に向かって配置されるにつれて徐々に弾性部材の伸長倍率を低くするように形成されている。 Thebelly side member 111 and the back side member 112 are provided around the waist of the exterior sheet 110, that is, from the waist 104 (104a, 104b) side of the exterior sheet 110 to the left leg opening 113 and the right leg opening 114 side. 121 (121a, 121b) is provided.
The waistline elastic body 121 (121a, 121b) extends from the waist 104 (104a, 104b) side of thepad holder 101 to the left and right leg openings 113, 114 side in the width direction (left-right direction, X direction) of the exterior sheet 110. It is comprised from the some thread-like elastic member arrange | positioned. Here, the tension of the elastic members constituting the waist elastic body 121 (121a, 121b) gradually becomes weaker from the waist 104 (104a, 104b) of the pad holder 101 toward the left and right leg openings 113, 114. It is formed as follows. That is, the elastic member arranged on the left and right leg openings 113, 114 side (lower end side) is more than the elastic member arranged on the waist portion 104 (104a, 104b) side (upper end side) than the elastic member. It is provided to reduce the tension. Specifically, the waistline elastic body 121 (121a, 121b) has left and right leg openings from the waist 104 (104a, 104b) when the elastic member is extended and joined between the outer sheet 110a and the inner sheet 110b. The elastic member is formed so as to gradually reduce the expansion ratio as it is arranged toward the portions 113 and 114.
胴周り弾性体121(121a,121b)は、外装シート110の幅方向(左右方向、X方向)において、パッドホルダー101の腰部104(104a,104b)側から左右の脚開口部113、114側にかけて配置された複数の糸状の弾性部材から構成されている。ここで、胴周り弾性体121(121a,121b)を構成する弾性部材は、パッドホルダー101の腰部104(104a,104b)から左右の脚開口部113、114へ向かうにつれて、徐々に張力が弱くなるように形成されている。すなわち、左右の脚開口部113、114側(下端側)に配置される弾性部材は、その弾性部材よりも腰部104(104a,104b)側(上端側)に配置される弾性部材に比して張力が弱くなるよう設けられている。具体的には、胴周り弾性体121(121a,121b)は、弾性部材が外面シート110a及び内面シート110b間に伸長させて接合される場合に、腰部104(104a,104b)から左右の脚開口部113、114側に向かって配置されるにつれて徐々に弾性部材の伸長倍率を低くするように形成されている。 The
The waistline elastic body 121 (121a, 121b) extends from the waist 104 (104a, 104b) side of the
また、外装シート110の胴周りには、胴周り弾性体121(121a,121b)の張力が及ばない非弾性部P(図4中の一点鎖線内)が設けられている。この非弾性部Pは、外装シート110の幅方向(左右方向、X方向)の中心線C1に対して線対称であって、腰部104(104a,104b)と左右の脚開口部113、114との間に設けられ、腰部104(104a,104b)から左右の脚開口部113、114に向かうにつれて、その幅寸法(左右幅)が徐々に大きくなるように形成されている。
ここで、非弾性部Pは、着用者によって吸収性物品が任意に選定されて配置される場合があるため、配置される吸収性物品の幅寸法(左右幅)を予め想定した上で、その幅方向(左右方向、X方向)の寸法を決定するのが望ましい。すなわち、非弾性部Pの幅寸法(左右幅)は、予め想定した吸収性物品の幅寸法(左右幅)と同等以下に形成されるのが望ましい。これにより、吸収性物品が配置されたパッドホルダー101を着用者が着用した場合に、吸収性物品が着用者の身体から離れてしまい、漏れなどが発生してしまうのを抑制することができる。 Further, a non-elastic portion P (within a one-dot chain line in FIG. 4) where the tension of the waist elastic body 121 (121a, 121b) does not reach is provided around the waist of theexterior sheet 110. The inelastic part P is line symmetric with respect to the center line C1 in the width direction (left and right direction, X direction) of the exterior sheet 110, and includes the waist 104 (104a, 104b) and the left and right leg openings 113, 114. The width dimension (left-right width) is gradually increased from the waist 104 (104a, 104b) toward the left and right leg openings 113, 114.
Here, since the absorbent article may be arbitrarily selected and arranged by the wearer, the non-elastic part P is assumed in advance after assuming the width dimension (left and right width) of the absorbent article to be arranged. It is desirable to determine the dimension in the width direction (left-right direction, X direction). That is, it is desirable that the width dimension (left-right width) of the inelastic part P is formed to be equal to or less than the width dimension (left-right width) of the absorbent article assumed in advance. Thereby, when a wearer wearspad holder 101 in which an absorptive article is arranged, it can control that an absorptive article leaves from a wearer's body and a leak etc. occur.
ここで、非弾性部Pは、着用者によって吸収性物品が任意に選定されて配置される場合があるため、配置される吸収性物品の幅寸法(左右幅)を予め想定した上で、その幅方向(左右方向、X方向)の寸法を決定するのが望ましい。すなわち、非弾性部Pの幅寸法(左右幅)は、予め想定した吸収性物品の幅寸法(左右幅)と同等以下に形成されるのが望ましい。これにより、吸収性物品が配置されたパッドホルダー101を着用者が着用した場合に、吸収性物品が着用者の身体から離れてしまい、漏れなどが発生してしまうのを抑制することができる。 Further, a non-elastic portion P (within a one-dot chain line in FIG. 4) where the tension of the waist elastic body 121 (121a, 121b) does not reach is provided around the waist of the
Here, since the absorbent article may be arbitrarily selected and arranged by the wearer, the non-elastic part P is assumed in advance after assuming the width dimension (left and right width) of the absorbent article to be arranged. It is desirable to determine the dimension in the width direction (left-right direction, X direction). That is, it is desirable that the width dimension (left-right width) of the inelastic part P is formed to be equal to or less than the width dimension (left-right width) of the absorbent article assumed in advance. Thereby, when a wearer wears
本実施形態では、非弾性部Pは、幅方向(左右幅)の寸法が、腹側部材111及び背側部材112の各々の腰部104(104a,104b)側から左右の脚開口部113、114側に向かうにつれて徐々に大きくなるように、略三角形状に形成される。そのため、胴周り弾性体121(121a,121b)は、非弾性部Pの略三角形状の外側に形成されることとなり、幅方向(左右方向、X方向)の寸法が、腰部104(104a,104b)側から左右の脚開口部13、14側に向かうにつれて徐々に短くなる。
In the present embodiment, the non-elastic portion P has a width direction (left-right width) dimension, and the left and right leg openings 113, 114 from the waist 104 (104a, 104b) side of each of the abdominal member 111 and the back member 112. It is formed in a substantially triangular shape so as to gradually increase toward the side. Therefore, the waist elastic body 121 (121a, 121b) is formed on the substantially triangular outer side of the non-elastic portion P, and the dimension in the width direction (left-right direction, X direction) is the waist portion 104 (104a, 104b). ) Gradually decreases from the side toward the left and right leg openings 13, 14 side.
このように、胴周り弾性体121(121a,121b)の腰部104(104a,104b)側の一部が、非弾性部Pの略三角形状の外側に形成されていることによって、着用者の腰に対するパッドホルダー101の締め付けの向きを斜め上方に変化させることができる。これにより、パッドホルダー101の胴周りが、腰周りの両側から股部方向へ、弧を描くように曲線状に曲がるため、着用者のお腹周りを締め付けずに腸骨に沿い、パッドホルダー101の着用時のフィット性や、ずれ落ち抑制効果を更に向上させることができる。
As described above, a part of the waist elastic body 121 (121a, 121b) on the side of the waist 104 (104a, 104b) is formed on the outer side of the inelastic part P in a substantially triangular shape. The direction of tightening of the pad holder 101 with respect to can be changed obliquely upward. As a result, the waist of the pad holder 101 bends in a curved shape so as to draw an arc from both sides of the waist toward the crotch. It is possible to further improve the fit at the time of wearing and the slip-off suppressing effect.
また、外装シート110に非弾性部Pが設けられることによって、上述のように幅方向における弾性部材の長さが腰部104(104a,104b)側から左右の脚開口部113、114側に向かって配置されるにつれて徐々に短くなるので、パッドホルダー101の胴周りは、全体で見た場合、腰部104(104a,104b)側から左右の脚開口部113、114側に向かうにつれて徐々に胴周り弾性体121(121a,121b)の張力が存在しない領域が広くなる。そのため、パッドホルダー101は、着用者の腹部及び臀部に対する締め付けを身体の形状に合わせて変化させることができ、着用時のフィット性を実現しつつ、パッドホルダー101のずれ落ちを抑制することができる。
Further, by providing the non-elastic portion P in the exterior sheet 110, the length of the elastic member in the width direction is from the waist portion 104 (104a, 104b) side toward the left and right leg opening portions 113, 114 side as described above. Since it gradually shortens as it is arranged, the waist circumference of the pad holder 101 is gradually elastic as it goes from the waist 104 (104a, 104b) side to the left and right leg openings 113, 114 when viewed as a whole. The region where the tension of the body 121 (121a, 121b) does not exist is widened. Therefore, the pad holder 101 can change the tightening of the wearer's abdomen and buttocks according to the shape of the body, and can suppress the slipping of the pad holder 101 while realizing fit at the time of wearing. .
以上より、本実施形態のパッドホルダー101は、外装シート110の腰部104(104a,104b)側から左右の脚開口部113、114側に向かうにつれて徐々に締め付けが弱くなるように形成されているので、パッドホルダー101を着用者の腹部及び臀部にフィットさせることができ、また、パッドホルダー101がずれ落ちてしまうのを抑制することができる。
また、パッドホルダー101は、左右の脚開口部113、114側に配置される胴周り弾性体121(121a,121b)の弾性部材が、その弾性部材よりも腰部104(104a,104b)側に配置される弾性部材に比して、張力が弱くなるように形成されているので、より具体的に胴周り弾性体121(121a,121b)の締め付けの変化を実現することができる。
更に、パッドホルダー101は、非弾性部Pが、腰部104(104a,104b)側から左右の脚開口部113、114側に向かうにつれて、その幅寸法が徐々に大きくなるように形成されているので、より具体的に胴周り弾性体121(121a,121b)の締め付けの変化を実現することができる。
また、パッドホルダー101は、非弾性部Pの幅寸法が、腰部104(104a,104b)から各開口部113、114に向かうにつれて、徐々に大きくなるように形成されている。これにより、パッドホルダー101は、股部105に吸収性物品が配置された状態で使用された場合に、液状体を吸収した吸収性物品の重みによって、着用者の身体からパッドホルダー101がずれ落ちてしまうのを抑制することができる。 As described above, thepad holder 101 of the present embodiment is formed so that the tightening is gradually weakened from the waist 104 (104a, 104b) side of the exterior sheet 110 toward the left and right leg openings 113, 114. The pad holder 101 can be fitted to the wearer's abdomen and buttocks, and the pad holder 101 can be prevented from slipping down.
Further, in thepad holder 101, the elastic member of the waist elastic body 121 (121a, 121b) arranged on the left and right leg opening portions 113, 114 side is arranged on the waist 104 (104a, 104b) side than the elastic member. Since the tension is formed so as to be weaker than that of the elastic member, the change in tightening of the waistline elastic body 121 (121a, 121b) can be realized more specifically.
Further, thepad holder 101 is formed such that the width of the inelastic portion P gradually increases from the waist portion 104 (104a, 104b) side toward the left and right leg opening portions 113, 114. More specifically, the tightening change of the waist elastic body 121 (121a, 121b) can be realized.
Thepad holder 101 is formed so that the width dimension of the inelastic portion P gradually increases as it goes from the waist 104 (104a, 104b) to the openings 113, 114.
