トップシート21は透液性の材料、例えば、親水性繊維により形成された不織布であり、着用者からの排泄物の水分を速やかに捕捉して吸収コア22へと移動させる。トップシート21として利用される不織布は、例えば、ポイントボンド不織布やエアスルー不織布、スパンボンド不織布であり、これらの不織布を形成する親水性繊維としては通常、セルロースやレーヨン、コットン等が用いられる。なお、トップシート21として、表面を界面活性剤により親水処理した疎水性繊維(例えば、ポリプロピレン、ポリエチレン、ポリエステル、ポリアミド、ナイロン)にて形成された透液性の不織布が利用されてもよく、また、開孔を有するプラスチックフィルムが利用されてもよい。   The top sheet 21 is a non-woven fabric formed of a liquid-permeable material, for example, a hydrophilic fiber, and quickly captures moisture of excrement from the wearer and moves it to the absorbent core 22. Nonwoven fabrics used as the top sheet 21 are, for example, point bond nonwoven fabrics, air-through nonwoven fabrics, and spunbond nonwoven fabrics, and cellulose, rayon, cotton, and the like are usually used as hydrophilic fibers that form these nonwoven fabrics. As the top sheet 21, a liquid-permeable nonwoven fabric formed of hydrophobic fibers (for example, polypropylene, polyethylene, polyester, polyamide, nylon) whose surface is hydrophilically treated with a surfactant may be used. Alternatively, a plastic film having an aperture may be used.

吸収コア22は、親水性繊維(例えば、粉砕したパルプ繊維やセルロース繊維)に粒状の吸水性ポリマー(例えば、SAP(Super Absorbent Polymer))を混合したものをティッシュペーパーや透液性不織布等の被覆シートにより包み込んで形成され、トップシート21を透過した水分を吸収して迅速に固定する。親水性繊維を包む被覆シートは、親水性繊維および吸水性ポリマーとホットメルト接着剤により接合されて、親水性繊維の型崩れ、および、吸水性ポリマーの脱落(特に、吸水後における脱落)を防止する。   The absorbent core 22 is made of a mixture of a hydrophilic fiber (for example, pulverized pulp fiber or cellulose fiber) mixed with a granular water-absorbing polymer (for example, SAP (Super Absorbent Polymer)) such as tissue paper or a liquid-permeable nonwoven fabric. It is formed by wrapping with a sheet and absorbs moisture that has passed through the top sheet 21 to quickly fix it. The cover sheet that wraps the hydrophilic fiber is bonded to the hydrophilic fiber and the water-absorbing polymer with a hot-melt adhesive to prevent the hydrophilic fiber from losing its shape and the water-absorbing polymer from falling off (especially after water absorption). To do.

バックシート23は、撥水性または不透液性のプラスチックフィルムであり、トップシート21を透過した水分、および、吸収コア22に一旦吸収された水分が、外装シート4側にしみ出すのを防止する。着用者の快適性の観点からは、通気性を有するプラスチックフィルムがバックシート23として利用されることが好ましい。バックシート23としては、撥水性または不透液性の不織布や当該不織布の着用者側に撥水性または不透液性のプラスチックフィルムが積層された積層シートが利用されてもよい。バックシート23に利用される不織布は、例えば、スパンボンド不織布やメルトブロー不織布、SMS(スパンボンド・メルトブロー・スパンボンド)不織布であり、必要に応じて撥水処理が施されてもよい。   The back sheet 23 is a water-repellent or liquid-impervious plastic film, and prevents moisture that has permeated through the top sheet 21 and moisture that has been absorbed by the absorbent core 22 from seeping out to the exterior sheet 4 side. . From the viewpoint of the wearer's comfort, a breathable plastic film is preferably used as the back sheet 23. As the back sheet 23, a water-repellent or liquid-impervious nonwoven fabric or a laminated sheet in which a water-repellent or liquid-impervious plastic film is laminated on the wearer side of the nonwoven fabric may be used. Nonwoven fabrics used for the backsheet 23 are, for example, spunbond nonwoven fabrics, meltblown nonwoven fabrics, and SMS (spunbond / meltblown / spunbond) nonwoven fabrics, and may be subjected to water repellent treatment as necessary.

図7は、製造途上の外装シート4を示す平面図である。図7に示すように、外装シート4が形成される際には、第1シート41および/または第2シート42の全面に亘ってカーテンスプレー等によりホットメルト接着剤が塗布された後、脚部弾性部材44となる予定の弾性部材である複数の弾性糸844が、中間部前部4022および中間部後部4023の一対の脚部非伸縮部491(図6参照)となる予定の部位8491(図7中において二点鎖線にて囲む部位であり、以下、単に「脚部非伸縮部8491」という。)を通って(すなわち、一対の脚部非伸縮部8491の一方から他方に亘って)、第1シート41および第2シート42に伸張状態にて接合される。   FIG. 7 is a plan view showing the exterior sheet 4 being manufactured. As shown in FIG. 7, when the exterior sheet 4 is formed, after the hot melt adhesive is applied over the entire surface of the first sheet 41 and / or the second sheet 42 by curtain spray or the like, A plurality of elastic yarns 844, which are elastic members scheduled to become the elastic member 44, are portions 8491 (FIG. 6) that are to be a pair of leg non-stretchable portions 491 (see FIG. 6) of the intermediate front portion 4022 and the intermediate rear portion 4023. 7 is a part surrounded by a two-dot chain line, and hereinafter referred to simply as “a leg non-stretchable part 8491”) (that is, from one of the pair of leg non-stretchable parts 8491 to the other), The first sheet 41 and the second sheet 42 are joined in an extended state.

また、弾性糸844の接合と並行して、第1中間部弾性部材47および第2中間部弾性部材48(図6参照)となる予定の弾性部材である複数の弾性糸847,848の全長に亘ってホットメルト接着剤が塗布された後、複数の弾性糸847,848がそれぞれ、中間部前部4022および中間部後部4023の中間非伸縮部492(図6参照)となる予定の部位8492(図7中において二点鎖線にて囲む部位であり、以下、単に「中間非伸縮部8492」という。)を通って、第1シート41および第2シート42に伸張状態にて接合される。   In parallel with the joining of the elastic yarn 844, the entire length of the plurality of elastic yarns 847, 848, which are elastic members that are to be the first intermediate elastic member 47 and the second intermediate elastic member 48 (see FIG. 6), After the hot melt adhesive is applied, the plurality of elastic yarns 847 and 848 are portions 8492 (see FIG. 6) that are to become the intermediate non-expandable portions 492 (see FIG. 6) of the intermediate front portion 4022 and the intermediate rear portion 4023, respectively. In FIG. 7, a portion surrounded by a two-dot chain line, and simply referred to as “intermediate non-stretchable portion 8492”), is joined to the first sheet 41 and the second sheet 42 in an extended state.

これにより、中間部前部4022の一対の脚部非伸縮部8491の上側(すなわち、前方部401側)において弾性糸844と弾性糸847とが交差して中間部前部4022に一対の交差領域493が形成され、中間部後部4023の一対の脚部非伸縮部8491の上側(すなわち、後方部403側)において弾性糸844と弾性糸848とが交差して中間部後部4023に一対の交差領域493が形成される。   As a result, the elastic yarn 844 and the elastic yarn 847 intersect on the upper side (that is, the front portion 401 side) of the pair of leg portion non-stretchable portions 8491 of the intermediate portion front portion 4022, and a pair of intersecting regions in the middle portion front portion 4022. 493 is formed, and the elastic yarn 844 and the elastic yarn 848 intersect each other on the upper side (that is, the rear portion 403 side) of the pair of leg portion non-stretchable portions 8491 of the intermediate portion rear portion 4023 to form a pair of intersecting regions in the intermediate portion rear portion 4023. 493 is formed.

そして、中間部前部4022の一対の脚部非伸縮部8491および中間非伸縮部8492、並びに、中間部後部4023の一対の脚部非伸縮部8491および中間非伸縮部8492において、複数の切断刃を有する回転刃等により、弾性糸844,847,848が第1シート41および第2シート42と共に複数箇所にて切断されて伸縮力を失う。これにより、図2に示す中間部前部4022において、脚部弾性部材44および第1中間部弾性部材47、並びに、一対の脚部非伸縮部491および中間非伸縮部492が形成される。また、図3に示す中間部後部4023において、脚部弾性部材44および第2中間部弾性部材48、並びに、一対の脚部非伸縮部491および中間非伸縮部492が形成される。図7の切断された弾性糸844,847,848の細片は、第1シート41と第2シート42との間において、第1シート41および第2シート42を収縮させることなく収縮している。   In the pair of leg non-stretchable parts 8491 and intermediate non-stretchable parts 8492 of the intermediate front part 4022, a plurality of cutting blades in the pair of leg non-stretchable parts 8491 and intermediate non-stretchable parts 8492 of the intermediate rear part 4023 The elastic yarns 844, 847, and 848 are cut at a plurality of locations together with the first sheet 41 and the second sheet 42 by a rotary blade or the like and loses expansion and contraction force. Accordingly, the leg elastic member 44 and the first intermediate elastic member 47, and the pair of leg non-stretchable parts 491 and intermediate non-stretchable parts 492 are formed in the intermediate front part 4022 shown in FIG. Further, in the intermediate rear part 4023 shown in FIG. 3, a leg elastic member 44 and a second intermediate elastic member 48, and a pair of leg non-expandable parts 491 and an intermediate non-expandable part 492 are formed. The strips of the cut elastic yarns 844, 847, and 848 in FIG. 7 are contracted between the first sheet 41 and the second sheet 42 without contracting the first sheet 41 and the second sheet 42. .

なお、実際には、脚部弾性部材44、第1中間部弾性部材47および第2中間部弾性部材48となる弾性部材(すなわち、弾性糸844,847,848)の接合は、第1シート41が連続的につながっているシート部材、および、第2シート42が連続的につながっているシート部材に対して行われ、弾性部材の切断は、これらのシート部材が接合されたもの(すなわち、外装シート4が連続的につながっている連続体であるシート部材)に対して行われる。また、脚部開口12に対応する切り欠き部812は、弾性部材の切断後に形成される。   In practice, the elastic members (that is, the elastic yarns 844, 847, 848) to be the leg elastic member 44, the first intermediate elastic member 47, and the second intermediate elastic member 48 are joined by the first sheet 41. Are continuously connected to the sheet member and the sheet member to which the second sheet 42 is continuously connected, and the elastic member is cut by joining these sheet members (that is, the exterior member). The sheet member is a continuous member in which the sheets 4 are continuously connected. The notch 812 corresponding to the leg opening 12 is formed after the elastic member is cut.

以上に説明したように、吸収性物品1では、外装シート4の中間部前部4022において、脚部弾性部材44と第1中間部弾性部材47とが交差する一対の交差領域493が一対の脚部開口12近傍に設けられ、交差領域493および交差領域493近傍の部位が脚部弾性部材44および第1中間部弾性部材47により収縮される。これにより、外装シート4の脚部開口12近傍の部位が広がってしまうことが抑制され、吸収性物品1の外観が向上される。   As described above, in the absorbent article 1, the pair of intersecting regions 493 where the leg elastic member 44 and the first intermediate elastic member 47 intersect in the intermediate front part 4022 of the exterior sheet 4 are a pair of legs. It is provided in the vicinity of the opening 12, and the intersection region 493 and the portion in the vicinity of the intersection region 493 are contracted by the leg elastic member 44 and the first intermediate elastic member 47. Thereby, it is suppressed that the site | part of leg part opening 12 vicinity of the exterior sheet | seat 4 spreads, and the external appearance of the absorbent article 1 is improved.

また、吸収性物品1では、各脚部開口12近傍において、脚部弾性部材44と第1中間部弾性部材47との交差領域493に隣接する部位が、伸縮性を有しない脚部非伸縮部491とされる。これにより、脚部弾性部材44および第1中間部弾性部材47による交差領域493および交差領域493近傍の部位の過剰な収縮が防止されるため、外装シート4の脚部開口12近傍の部位の着用者に対する適度な密着性を維持しつつ脚部開口12近傍の部位の柔軟性を向上することができる。その結果、吸収性物品1の脚周りの部位の着用者に対する密着性が過剰に大きくなることが防止され(すなわち、吸収性物品1により着用者の脚周りがきつく圧迫されることが防止され)、脚部開口12からの排泄物の漏れを防止しつつ吸収性物品1の着用感を快適なものとすることができる。また、吸収性物品1の装着時に、着用者の脚を脚部開口12に円滑に挿入することができるため、吸収性物品1の装着が容易とされる。   Further, in the absorbent article 1, in the vicinity of each leg opening 12, a portion adjacent to the intersection region 493 between the leg elastic member 44 and the first intermediate elastic member 47 is a non-stretchable leg portion. 491. This prevents excessive contraction of the portion near the intersection region 493 and the intersection region 493 by the leg elastic member 44 and the first intermediate portion elastic member 47, so that the portion near the leg opening 12 of the exterior sheet 4 is worn. It is possible to improve the flexibility of the portion in the vicinity of the leg opening 12 while maintaining appropriate adhesion to the person. As a result, it is possible to prevent the adhesiveness of the part around the leg of the absorbent article 1 from being excessively increased (that is, the absorbent article 1 is prevented from being tightly pressed around the leg of the wearer). Moreover, the wearing feeling of the absorbent article 1 can be made comfortable while preventing leakage of excrement from the leg opening 12. Moreover, since a wearer's leg can be smoothly inserted in the leg part opening 12 at the time of mounting | wearing of the absorbent article 1, mounting | wearing of the absorbent article 1 is made easy.

さらには、中間部前部4022において第1中間部弾性部材47により中間部ギャザが形成されことにより、中間部402の着用者に対する密着性を向上することができるため、吸収性物品1の外観がより向上される。また、尿等の排泄物が吸収体2により吸収された状態においても、中間部ギャザにより中間部402が大きく膨らんでしまうことが抑制され、外観の向上が実現されるとともに排泄物の漏れをより確実に防止することができる。   Furthermore, since the intermediate part gather is formed by the first intermediate part elastic member 47 in the intermediate part front part 4022, the adhesiveness of the intermediate part 402 to the wearer can be improved, so that the appearance of the absorbent article 1 is improved. More improved. Further, even when excrement such as urine is absorbed by the absorbent body 2, the middle part 402 is prevented from being greatly swollen by the middle part gather, and the appearance is improved and more excrement is leaked. It can be surely prevented.

吸収性物品1では、外装シート4の中間部後部4023において、中間部前部4022と同様に、第2中間部弾性部材48が一対の脚部弾性部材44と交差領域493において交差するとともに伸縮性を有しない一対の脚部非伸縮部491が交差領域493に隣接して配置される。これにより、吸収性物品1の外観をより向上することができるとともに外装シート4の脚部開口12近傍の部位の柔軟性をより向上することができる。また、中間部402の着用者に対する密着性がより向上される。   In the absorbent article 1, at the intermediate rear part 4023 of the exterior sheet 4, the second intermediate elastic member 48 intersects with the pair of leg elastic members 44 at the intersection region 493 as well as the intermediate front part 4022 and is stretchable. A pair of leg non-stretchable portions 491 that do not have a gap is disposed adjacent to the intersection region 493. Thereby, while being able to improve the external appearance of the absorbent article 1, the softness | flexibility of the site | part vicinity of the leg part opening 12 of the exterior sheet | seat 4 can be improved more. Moreover, the adhesiveness with respect to the wearer of the intermediate part 402 is improved more.

外装シート4では、中間部前部4022において一対の脚部非伸縮部491が一対の交差領域493の下側に位置することにより、着用者の脚周りの内腿側において外装シート4の柔軟性が向上され、脚周りの外側において外装シート4の着用者に対する密着性が向上される。このように、外的刺激に対して比較的敏感な内腿側において外装シート4の着用者に対する密着性を低減することにより、吸収性物品1の着用感をより向上することができる。また、中間部後部4023においても、中間部前部4022と同様に、一対の脚部非伸縮部491が一対の交差領域493の下側に位置することにより、吸収性物品1の着用感をさらに向上することができる。   In the exterior sheet 4, the pair of leg non-stretchable parts 491 is positioned below the pair of intersecting regions 493 in the intermediate front part 4022, so that the flexibility of the exterior sheet 4 on the inner thigh side around the wearer's legs is achieved. Is improved, and the adhesion of the exterior sheet 4 to the wearer is improved outside the legs. Thus, the feeling of wear of the absorbent article 1 can be further improved by reducing the adhesion of the outer sheet 4 to the wearer on the inner thigh side that is relatively sensitive to external stimuli. Moreover, also in the intermediate part rear part 4023, similarly to the intermediate part front part 4022, the pair of leg non-stretchable parts 491 are positioned below the pair of intersecting regions 493, thereby further enhancing the wearing feeling of the absorbent article 1. Can be improved.

外装シート4の脚部開口12近傍では、第1中間部弾性部材47の左右両端部(すなわち、第1中間部弾性部材47の右側の弾性部材471の右側端部および左側の弾性部材471の左側端部)が、一対の脚部開口12のエッジ121に位置しているため、脚部弾性部材44および第1中間部弾性部材47が収縮することにより、外装シート4の脚部開口12近傍の部位(特に、エッジ121近傍の部位)が広がってしまうことがより一層抑制され、吸収性物品1の外観がさらに向上される。また、第2中間部弾性部材48の左右両端部が、第1中間部弾性部材47と同様に、一対の脚部開口12のエッジ121に位置することにより、吸収性物品1の外観がより一層向上される。   In the vicinity of the leg opening 12 of the exterior sheet 4, the left and right ends of the first intermediate elastic member 47 (that is, the right end of the right elastic member 471 of the first intermediate elastic member 47 and the left side of the left elastic member 471. End portion) is located at the edge 121 of the pair of leg openings 12, and the leg elastic member 44 and the first intermediate elastic member 47 contract, so that the vicinity of the leg opening 12 of the exterior sheet 4. The spread of the portion (particularly, the portion near the edge 121) is further suppressed, and the appearance of the absorbent article 1 is further improved. Further, both the left and right ends of the second intermediate elastic member 48 are positioned at the edges 121 of the pair of leg openings 12 in the same manner as the first intermediate elastic member 47, thereby further improving the appearance of the absorbent article 1. Be improved.

吸収性物品1では、第1中間部弾性部材47が吸収コア22の左右両側に配置される一対の弾性部材471を有し、外装シート4の一対の弾性部材471の間の部位が、伸縮性を有しない中間非伸縮部492とされる。このように、第1中間部弾性部材47が吸収コア22と重ならないように吸収コア22を避けて設けられることにより、中間部402における吸収コア22の縒れを抑制することができる。その結果、吸収性物品1の着用感が向上されるとともに、吸収コア22の縒れによる吸収性物品1の吸収性低下が防止されて排泄物の漏れがさらに確実に防止される。第2中間部弾性部材48においても同様に、吸収コア22の左右両側に配置された一対の弾性部材481の間の部位が中間非伸縮部492とされることにより、中間部402における吸収コア22の縒れをより一層抑制することができる。   In the absorbent article 1, the first intermediate elastic member 47 has a pair of elastic members 471 disposed on the left and right sides of the absorbent core 22, and a portion between the pair of elastic members 471 of the exterior sheet 4 is stretchable. The intermediate non-expandable portion 492 does not have the same. As described above, the first intermediate elastic member 47 is provided so as to avoid the absorption core 22 so as not to overlap with the absorption core 22, thereby suppressing the bending of the absorption core 22 in the intermediate portion 402. As a result, the wearing feeling of the absorbent article 1 is improved, and a decrease in the absorbency of the absorbent article 1 due to the sag of the absorbent core 22 is prevented, thereby further preventing the excrement from leaking. Similarly, in the second intermediate elastic member 48, the portion between the pair of elastic members 481 arranged on the left and right sides of the absorbent core 22 is set as an intermediate non-stretchable portion 492, whereby the absorbent core 22 in the intermediate portion 402. Can be further suppressed.

第1中間部弾性部材47および第2中間部弾性部材48では、各弾性部材471,481が、吸収コア22の左右両端縁と一対の脚部開口12との間の部位に連続して配置されることにより、当該部位において左右方向に連続する中間部ギャザが形成されて中間部ギャザの強度が向上される。これにより、外装シート4の脚部開口12近傍の部位の広がりがさらに抑制されて吸収性物品1の外観がより向上され、また、中間部402の着用者に対する密着性もより向上される。   In the first intermediate elastic member 47 and the second intermediate elastic member 48, the elastic members 471 and 481 are continuously arranged at a portion between the left and right edges of the absorbent core 22 and the pair of leg openings 12. As a result, an intermediate gather that is continuous in the left-right direction is formed at the portion, and the strength of the intermediate gather is improved. Thereby, the breadth of the site | part vicinity of the leg part opening 12 of the exterior sheet | seat 4 is further suppressed, the external appearance of the absorbent article 1 is improved more, and the adhesiveness with respect to the wearer of the intermediate part 402 is also improved more.

なお、吸収性物品1では、中間部402の着用者に対する密着性をさらに向上する必要がある場合には、第1中間部弾性部材47および/または第2中間部弾性部材48が、一対の脚部開口12の一方から他方に亘って、一対の脚部弾性部材44と交差するとともに吸収コア22と重なるように左右方向に沿って配置されてもよい。この場合、吸収コア22の縒れを抑制するために、吸収コア22の剛性が必要に応じて高くされてもよい。   In the absorbent article 1, when it is necessary to further improve the adhesion of the intermediate portion 402 to the wearer, the first intermediate elastic member 47 and / or the second intermediate elastic member 48 are a pair of legs. It may be arranged along the left-right direction so as to cross the pair of leg elastic members 44 and overlap the absorbent core 22 from one to the other of the part openings 12. In this case, the rigidity of the absorbent core 22 may be increased as necessary in order to prevent the absorbent core 22 from twisting.

吸収性物品1の製造では、中間部前部4022の一対の脚部非伸縮部491、および、中間部後部4023の一対の脚部非伸縮部491をそれぞれ通って第1シート41および第2シート42に接合された弾性糸844が、各脚部非伸縮部491において切断されて伸縮性を失うことにより脚部弾性部材44が形成される。これにより、外装シート4および吸収性物品1を容易に形成することができる。   In the manufacture of the absorbent article 1, the first sheet 41 and the second sheet pass through the pair of leg non-stretchable parts 491 of the middle front part 4022 and the pair of leg non-stretchable parts 491 of the middle rear part 4023, respectively. The elastic part 844 joined to 42 is cut in each leg part non-expandable part 491, and loses elasticity, and the leg elastic member 44 is formed. Thereby, the exterior sheet | seat 4 and the absorbent article 1 can be formed easily.

The first intermediate elastic member 47 and the second intermediate elastic member 48 are formed by being cut at each non-expandable portion and losing elasticity. Thereby, the exterior sheet 4 and the absorbent article 1 can be formed more easily.

次に、本発明の第2の実施の形態に係る吸収性物品について説明する。図8は、第2の実施の形態に係る吸収性物品1aを展開した状態で着用者側から見た平面図である。図8に示すように、吸収性物品1aでは、外装シート4の中間部402において、中間部前部4022および中間部後部4023の各中間非伸縮部492の左右両端部が吸収体2の左右両側縁に位置する。吸収性物品1aのその他の構成は、図1ないし図6に示す吸収性物品1と同様であり、以下の説明において同符号を付す。   Next, an absorbent article according to a second embodiment of the present invention will be described. FIG. 8: is the top view seen from the wearer side in the state which expand | deployed the absorbent article 1a which concerns on 2nd Embodiment. As shown in FIG. 8, in the absorbent article 1 a, in the intermediate portion 402 of the exterior sheet 4, the left and right ends of each intermediate non-stretchable portion 492 of the intermediate portion front portion 4022 and the intermediate portion rear portion 4023 are on the left and right sides of the absorbent body 2. Located on the edge. The other structure of the absorbent article 1a is the same as that of the absorbent article 1 shown in FIG. 1 thru | or FIG. 6, and attaches | subjects a same sign in the following description.

図8に示す吸収性物品1aでは、第1中間部弾性部材47は、第1の実施の形態と同様に一対の弾性部材471を有し、一対の弾性部材471は、吸収体2の左右両側縁と一対の脚部開口12(図1ないし図3参照)のエッジ121との間に連続して配置されて一対の脚部弾性部材44と交差する。また、第2中間部弾性部材48も、第1の実施の形態と同様に一対の弾性部材481を有し、一対の弾性部材481は、吸収体2の左右両側縁と一対の脚部開口12のエッジ121との間に連続して配置されて一対の脚部弾性部材44と交差する。そして、脚部弾性部材44と第1中間部弾性部材47および第2中間部弾性部材48との交差領域493の下側(すなわち、図1ないし図3に示す折り曲げ部4021側)に隣接して脚部非伸縮部491が設けられる。   In the absorbent article 1a shown in FIG. 8, the first intermediate elastic member 47 has a pair of elastic members 471 as in the first embodiment, and the pair of elastic members 471 are on the left and right sides of the absorbent body 2. It arrange | positions continuously between the edge and the edge 121 of a pair of leg part opening 12 (refer FIG. 1 thru | or FIG. 3), and cross | intersects a pair of leg part elastic member 44. FIG. Similarly to the first embodiment, the second intermediate elastic member 48 also has a pair of elastic members 481, and the pair of elastic members 481 includes the left and right side edges of the absorber 2 and the pair of leg openings 12. Between the pair of leg elastic members 44. Then, adjacent to the lower side of the intersection region 493 of the leg elastic member 44, the first intermediate elastic member 47, and the second intermediate elastic member 48 (that is, the bent portion 4021 side shown in FIGS. 1 to 3). A leg non-stretchable portion 491 is provided.

これにより、吸収性物品1aでは、第1の実施の形態と同様に、外装シート4の脚部開口12近傍の部位が広がってしまうことが抑制され、吸収性物品1aの外観が向上される。また、脚部弾性部材44と第1中間部弾性部材47および第2中間部弾性部材48との交差領域493および交差領域493近傍の部位の過剰な収縮が防止されるため、外装シート4の脚部開口12近傍の部位の着用者に対する適度な密着性を維持しつつ脚部開口12近傍の部位の柔軟性を向上することができる。   Thereby, in the absorbent article 1a, similarly to the first embodiment, it is possible to suppress the site in the vicinity of the leg opening 12 of the exterior sheet 4 from spreading, and the appearance of the absorbent article 1a is improved. Further, excessive contraction of the intersection region 493 between the leg elastic member 44, the first intermediate elastic member 47, and the second intermediate elastic member 48 and in the vicinity of the intersection region 493 is prevented. The flexibility of the site in the vicinity of the leg opening 12 can be improved while maintaining appropriate adhesion to the wearer in the site in the vicinity of the section opening 12.

吸収性物品1aでは、上述のように、中間非伸縮部492の左右両端部が吸収体2の左右両側縁に位置しており、中間部前部4022および中間部後部4023において、第1中間部弾性部材47および第2中間部弾性部材48が吸収体2と重ならないように吸収体2を避けて設けられる。これにより、中間部402における吸収コア22および吸収体2の縒れを抑制することができる。その結果、吸収性物品1aの着用感がより向上されるとともに、吸収性物品1aの吸収性低下が防止されて排泄物の漏れがさらに確実に防止される。   In the absorbent article 1a, as described above, the left and right end portions of the intermediate non-stretchable portion 492 are positioned on the left and right side edges of the absorbent body 2, and the intermediate portion front portion 4022 and the intermediate portion rear portion 4023 have a first intermediate portion. The elastic member 47 and the second intermediate elastic member 48 are provided avoiding the absorbent body 2 so as not to overlap the absorbent body 2. Thereby, the drooping of the absorption core 22 and the absorber 2 in the intermediate part 402 can be suppressed. As a result, the wearing feeling of the absorbent article 1a is further improved, and a decrease in the absorbency of the absorbent article 1a is prevented, thereby further preventing the excrement from leaking.

以上、本発明の実施の形態について説明してきたが、本発明は上記実施の形態に限定されるものではなく、様々な変更が可能である。   As mentioned above, although embodiment of this invention has been described, this invention is not limited to the said embodiment, A various change is possible.

上記実施の形態に係る吸収性物品の製造では、弾性糸844,847,848は、必ずしも第1シート41および第2シート42と共に切断される必要はなく、第1シート41および第2シート42の少なくとも一方と共に切断されていればよい。これにより、吸収性物品を容易に形成することができる。また、弾性糸844,847,848の切断は、例えば、圧縮空気のブローにより、あるいは、先端が鋭くない刃物を外装シート4に当接させた上で超音波を印加することにより、第1シート41および第2シート42を切断することなく行われてもよい。   In the manufacture of the absorbent article according to the above embodiment, the elastic yarns 844, 847, 848 are not necessarily cut together with the first sheet 41 and the second sheet 42, and the first sheet 41 and the second sheet 42 are not cut. What is necessary is just to have cut | disconnected with at least one. Thereby, an absorbent article can be formed easily. Further, the elastic yarns 844, 847, and 848 are cut by, for example, blowing the compressed air or applying an ultrasonic wave after bringing a blade whose tip is not sharp into contact with the exterior sheet 4 to apply the first sheet. It may be performed without cutting 41 and the second sheet 42.

吸収性物品の製造では、弾性糸844,847,848は、脚部非伸縮部491および中間非伸縮部492において必ずしも複数箇所にて切断される必要はなく、例えば、第1シート41および第2シート42の各非伸縮部となる部位にホットメルト接着剤を塗布せずに弾性糸844,847,848を第1シート41と第2シート42との間に伸張状態にて接合した後、各弾性糸が各非伸縮部となる部位において1箇所にて切断されてもよい。これにより、弾性糸844,847,848の非伸縮部と重なる部分が、第1シート41および第2シート42を収縮させることなく収縮して脚部非伸縮部491および中間非伸縮部492が形成される。   In the manufacture of the absorbent article, the elastic yarns 844, 847, 848 need not be cut at a plurality of locations in the leg non-stretchable portion 491 and the intermediate non-stretchable portion 492. For example, the first sheet 41 and the second sheet After the elastic yarns 844, 847, and 848 are joined in the stretched state between the first sheet 41 and the second sheet 42 without applying the hot melt adhesive to the portions that become the non-stretchable portions of the sheet 42, The elastic yarn may be cut at one place in each of the non-stretchable portions. As a result, the portions of the elastic yarns 844, 847, and 848 that overlap the non-stretchable portions contract without contracting the first sheet 41 and the second sheet 42 to form the leg non-stretchable portion 491 and the intermediate non-stretchable portion 492.
