Description

本発明は、パンツ型の使い捨ておむつ等のような、着用者の股部にあてがわれて排泄物を吸収する使い捨て吸収性物品に関する。 The present invention relates to a disposable absorbent article which is applied to a wearer's crotch and absorbs excrement, such as a pants-type disposable diaper.

近年、使い捨ておむつ、使い捨てパンツ、生理用ナプキンなどの使い捨て吸収性物品を用いる衛生材料の分野において、特に、中・軽度の失禁者に対する薄型で快適な吸収性物品の開発が求められている。上記中・軽度の失禁を対象とする使い捨て吸収性物品としては、着用者の歩行の動作を妨げることなく、より薄型で、はき心地のよい使い捨て吸収性物品が求められる場合が多い。 In recent years, in the field of sanitary materials using disposable absorbent articles such as disposable diapers, disposable pants, sanitary napkins, etc., development of a thin and comfortable absorbent article has been demanded particularly for moderate and mild incontinent persons. As the above-mentioned disposable absorbent articles intended for moderate and mild incontinence, disposable absorbent articles that are thinner and more comfortable to wear are often required without interfering with the walking motion of the wearer.

従来から使用されている使い捨て吸収性物品、例えば、パンツ型使い捨ておむつとしては、腹側部と背側部の上側にウエスト開口部が形成され、腹側部と背側部との間の股部両側に脚開口部が形成されてなるパンツ型の外装シートが設けられている。そして、このパンツ型の外装シートを構成する液不透過性のバックシートと、肌面側の液透過性のトップシートとで吸収材を挟み、この肌面側における左右側縁近傍に堤部（サイド立体ギャザー）を帯状に形成したものが知られている。このサイド立体ギャザーは、その頂部に糸ゴム等の弾性部材を挟んだ液不透過性のサイドシートからなり、弾性部材が収縮することによりサイドシートが立ち上がり、これによって尿や便等が堰き止められ、おむつの両側縁からの漏れ（横漏れ）が防止されるというものである。 Conventionally used disposable absorbent articles, for example, pants-type disposable diapers, a waist opening is formed on the upper side of the abdomen and the dorsal side, and the crotch between the abdomen and the dorsal side A pants-type exterior sheet having leg openings formed on both sides is provided. Then, the absorbent material is sandwiched between the liquid-impermeable back sheet constituting the pants-type exterior sheet and the liquid-permeable top sheet on the skin surface side, and a bank ( A side solid gather) is known which is formed in a band shape. This side three-dimensional gather is composed of a liquid-impermeable side sheet with an elastic member such as rubber thread sandwiched at the top, and the side sheet rises when the elastic member contracts, thereby blocking urine, feces, etc. The leakage (lateral leakage) from both side edges of the diaper is prevented.

このような従来の使い捨て吸収性物品については、例えば、特許文献１に開示されている。 Such a conventional disposable absorbent article is disclosed in Patent Document 1, for example.

次に、吸収性本体３について、図３及び図４に基づいて説明する。吸収性本体３は、略シート状の吸収材３１と、その吸収性本体３の左右両側端部に設けられるサイドシート３２とを備えている。また、吸収性本体３は、液透過性のトップシート３３と液不透過性のバックシート３４との間に、吸収材３１を挟み込んで構成されている。吸収材３１は、平面視略砂時計形状の略シート材であり、股下部４を中心にして前後方向に帯状に広がっている。このように構成される吸収性本体３は、外側シート部材２の股部２Ｂの肌面側に接合されている。この接合は、吸収性本体３と外側シート部材２との間にホットメルト等の接着剤を塗布して接着層５０を形成して行われる。また、本実施形態に係るサイドシート３２は、サイドシート３２の長手方向の寸法が、吸収性本体３の長手方向の寸法と略均等で、且つ、サイドシート３２の幅方向の寸法が、サイドシート３２の長手方向一方側端部から他方側端部にかけて均一になるように構成されている。なお、吸収性本体３の左右両側端部において、図４に示すように、折り畳まれたバックシート３４同士の間に接着層５１が、折り畳まれたバックシート３４の上面とトップシート３３の下面との間に接着層５２が、トップシート３３の上面とサイドシート３２の下面（図４では下側サイドシート３２ｃの下面）との間に接着層５３がそれぞれ形成されてそれぞれ接合されている。このような構成にすることにより、吸収材３１が吸収性本体３内に密封されている。 Next, the absorptive main body 3 is demonstrated based on FIG.3 and FIG.4. The absorbent main body 3 includes a substantially sheet-like absorbent material 31 and side sheets 32 provided at both left and right end portions of the absorbent main body 3. Further, the absorbent main body 3 is configured by sandwiching an absorbent material 31 between a liquid-permeable top sheet 33 and a liquid-impermeable back sheet 34. The absorbent material 31 is a substantially sheet material having a substantially hourglass shape in plan view, and spreads in a belt shape in the front-rear direction around the crotch part 4. The absorbent main body 3 configured in this way is joined to the skin side of the crotch 2B of the outer sheet member 2. This joining is performed by applying an adhesive such as hot melt between the absorbent main body 3 and the outer sheet member 2 to form the adhesive layer 50. Further, in the side sheet 32 according to the present embodiment, the longitudinal dimension of the side sheet 32 is substantially equal to the longitudinal dimension of the absorbent main body 3, and the lateral dimension of the side sheet 32 is the side sheet. It is comprised so that it may become uniform from 32 longitudinal direction one side edge part to the other side edge part. As shown in FIG. 4, the adhesive layer 51 is formed between the folded back sheets 34 and the bottom surface of the folded back sheet 34 and the bottom surface of the top sheet 33 at both left and right end portions of the absorbent main body 3. The adhesive layer 52 is formed between and bonded to the upper surface of the top sheet 33 and the lower surface of the side sheet 32 (the lower surface of the lower side sheet 32c in FIG. 4). With this configuration, the absorbent material 31 is sealed in the absorbent main body 3.

また、サイドシート３２の自由端部近傍には、サイドシート３２のほぼ全長にわたって第１起立用弾性部材３８が長手方向に伸長した状態で取り付けられている。この第１起立用弾性部材３８の収縮により第１起立用弾性部材３８が取り付けられているサイドシート３２の部位、つまり、サイドシート３２の第１起立用弾性部材３８の周辺部位がひだ状となり、上方に立ち上がった状態となる。当該サイドシート３２の部位を起立部３２１とすると、起立部３２１は立体ギャザーとして機能し、尿等をせき止めて使い捨て吸収性物品の両側縁部からの漏れ（横漏れ）を有効に防止させることができる。 Further, the first standing elastic member 38 is attached to the vicinity of the free end of the side seat 32 so as to extend in the longitudinal direction over almost the entire length of the side seat 32. Due to the contraction of the first standing elastic member 38, the portion of the side seat 32 to which the first standing elastic member 38 is attached, that is, the peripheral portion of the first standing elastic member 38 of the side seat 32 is pleated, It will stand up. If the part of the side sheet 32 is a standing part 321, the standing part 321 functions as a three-dimensional gather and can effectively prevent leakage (lateral leakage) from both side edges of the disposable absorbent article by urinating urine and the like. it can.

また、本実施形態に係る起立部３２１の起立幅Ｐは従来に比べて微少量に設定されており、その値としては、例えば、０．５乃至５ｍｍ程度である。ここでいう「微少量」とは、小さくとも起立部３２１が本来の立体ギャザーとしての機能を損なわない程度の大きさ、つまり、使い捨て吸収性物品１の両側縁部からの尿等の漏れを防止する防波堤としての機能を損なわない程度の大きさであればよい。このため、第１起立用弾性部材３８の収縮により上方に立ち上がる起立部３２１の起立幅Ｐが従来に比べて小さく、したがって、本実施形態に係る使い捨て吸収性物品１を着用者が着用したとき、脚を起立部３２１に引っかけることなくスムースに着用することができる。また、起立部３２１が着用者の肌に接触しても従来に比べて不快感が少ない。また、起立部３２１の大きさも従来に比べて小さいので、第１起立用弾性部材３８の収縮により反り易い。 Further, the standing width P of the standing portion 321 according to the present embodiment is set to a very small amount as compared with the conventional case, and the value is, for example, about 0.5 to 5 mm. “Small amount” as used herein refers to a size that does not impair the function of the original three-dimensional gather even if it is small, that is, prevents leakage of urine and the like from both side edges of the disposable absorbent article 1. As long as the function as a breakwater is not impaired. For this reason, when the wearer wears the disposable absorbent article 1 according to the present embodiment, the standing width P of the standing portion 321 that rises upward due to the contraction of the first standing elastic member 38 is smaller than the conventional one. The leg can be worn smoothly without being caught on the upright part 321. Moreover, even if the standing part 321 contacts a wearer's skin, there is little discomfort compared with the past. Further, since the size of the upright portion 321 is smaller than that of the conventional one, it is likely to warp due to the contraction of the first upright elastic member 38.

また、サイドシート３２は、サイドシート３２の自由端部を内向きに折曲可能な折曲部３２ａを長手方向に有し、折曲部３２ａを吸収性本体３の幅方向両側端部近傍に設けている。なお、折曲部３２ａの折り返し端部近傍には、サイドシート３２のほぼ全長にわたって第２起立用弾性部材３９が長手方向に伸長した状態で取り付けられている。この第２起立用弾性部材３９の収縮により、吸収性本体３自体の両側縁部近傍を上方に立ち上がらせる。 Further, the side seat 32 has a bent portion 32a that can be bent inward in the free end portion of the side seat 32 in the longitudinal direction, and the bent portion 32a is located in the vicinity of both end portions in the width direction of the absorbent main body 3. Provided. In addition, the elastic member 39 for 2nd standing is attached to the vicinity of the folding | turning edge part of the bending part 32a over the substantially full length of the side seat | sheet 32 in the longitudinal direction. By the contraction of the second standing elastic member 39, the vicinity of both side edges of the absorbent main body 3 itself is raised upward.

サイドシート３２は、図４に示すように、折曲部３２ａを軸に二つ折り状とされており、上側に位置する上側サイドシート３２ｂと、上側サイドシート３２ｂと対向する下側サイドシート３２ｃとの間に、折曲部３２ａから幅方向内側に所定の距離のところまでに長手方向にわたって幅方向の寸法が均一な接着層４０を形成させる。なお、上述したように下側サイドシート３２ｃはトップシート３３と接着層５３を介して接合している。ここで、上側サイドシート３２ｂにおいて、接着層４０が形成されている部位を基部３２２、基部３２２より幅方向内側に位置する部位を起立部３２１とする。また、立ち上がった状態での起立部３２１の先端部からトップシート３３の上面までの距離を起立部３２１の起立幅Ｐとし、接着層４０を形成している所定の距離、つまり、接着層４０の幅方向の寸法をＱとする。なお、起立部３２１と下側サイドシート３２ｃとの間には接着層は形成されておらず、起立部３２１の先端部はサイドシート３２の自由端部に相当する。このため、起立部３２１の先端部近傍に取り付けられている第１起立用弾性部材３８の収縮により、起立部３２１は上方に立ち上がったひだ状の立体ギャザーとなる。 As shown in FIG. 4, the side seat 32 is folded in two with the bent portion 32 a as an axis, and an upper side seat 32 b positioned on the upper side, and a lower side seat 32 c facing the upper side seat 32 b, In the meantime, the adhesive layer 40 having a uniform dimension in the width direction is formed over the longitudinal direction from the bent portion 32a to a predetermined distance inward in the width direction. As described above, the lower side sheet 32 c is joined to the top sheet 33 via the adhesive layer 53. Here, in the upper side sheet 32 b, a part where the adhesive layer 40 is formed is a base part 322, and a part located on the inner side in the width direction than the base part 322 is a standing part 321. Further, the distance from the tip of the standing part 321 to the upper surface of the top sheet 33 in the standing state is the standing width P of the standing part 321, and a predetermined distance for forming the adhesive layer 40, that is, the adhesive layer 40. Let the dimension in the width direction be Q. Note that an adhesive layer is not formed between the standing portion 321 and the lower side sheet 32 c, and the leading end portion of the standing portion 321 corresponds to the free end portion of the side sheet 32. Therefore, the upright portion 321 becomes a pleated three-dimensional gather that rises upward due to the contraction of the first upright elastic member 38 attached in the vicinity of the tip of the upright portion 321.

以上のような構成にすることにより、サイドシート３２の幅方向の寸法がサイドシート３２の長手方向一方側端部から他方側端部にかけて均一であるので、第１起立用弾性部材３８の収縮により立ち上がり易く、立ち上がった起立部３２１も長手方向にかけて均一となり、その結果、起立部３２１は幅方向一方側から見て綺麗な円弧を描く略弓状に反った状態となる。したがって、着用者の主に股関節部にフィットし、着用者に異物感や違和感を与えることなく、快適な着用性を確保することができる。 With the configuration as described above, the dimension in the width direction of the side seat 32 is uniform from one end portion to the other end portion in the longitudinal direction of the side seat 32. Therefore, the contraction of the first standing elastic member 38 The rising portion 321 that rises easily and becomes uniform in the longitudinal direction, and as a result, the rising portion 321 is warped in a substantially arcuate shape that forms a beautiful arc as viewed from one side in the width direction. Accordingly, the wearer mainly fits the hip joint, and comfortable wearability can be ensured without giving the wearer a feeling of foreign matter or discomfort.

また、接着層４０の幅方向の寸法も長手方向に均一であるので、接着層が形成されていない上側サイドシート３２ｂの部位の幅方向の寸法も長手方向に均一となる。接着層が形成されていない上側サイドシート３２ｂの部位は起立部３２１であるので、接着層４０の幅方向の寸法Ｑを調整することにより起立部３２１の起立幅Ｐを所望する大きさに適宜修正することができる。例えば、起立部３２１の起立幅Ｐを接着層４０の幅方向の寸法Ｑよりも小さくなるように設定する。図４に示すように、接着層４０が形成されているサイドシート３２の基部３２２と起立部３２１とは幅方向に繋がっており、接着層４０の幅方向の寸法Ｑを大きくすると、基部３２２からサイドシート３２の自由端部までの寸法、つまり、サイドシート３２の起立部３２１の先端部までの寸法が小さくなり、結果として、起立部３２１の起立幅であるＰの大きさも小さくなる。また、起立幅Ｐの大きさが微少量な起立部を新たに設ける必要はなく、従来から用いられているサイドシートを使用して所望する起立幅Ｐを有する起立部を得ることができる。 Further, since the dimension in the width direction of the adhesive layer 40 is also uniform in the longitudinal direction, the dimension in the width direction of the portion of the upper side sheet 32b where the adhesive layer is not formed is uniform in the longitudinal direction. Since the part of the upper side sheet 32b where the adhesive layer is not formed is the standing part 321, the standing width P of the standing part 321 is appropriately corrected to a desired size by adjusting the dimension Q in the width direction of the adhesive layer 40. can do. For example, the standing width P of the standing portion 321 is set to be smaller than the dimension Q in the width direction of the adhesive layer 40. As shown in FIG. 4, the base portion 322 and the upright portion 321 of the side sheet 32 on which the adhesive layer 40 is formed are connected in the width direction, and when the dimension Q in the width direction of the adhesive layer 40 is increased, the base portion 322 The dimension to the free end of the side seat 32, that is, the dimension to the tip of the upright portion 321 of the side seat 32 is reduced, and as a result, the size of P that is the standing width of the upright portion 321 is also reduced. In addition, it is not necessary to newly provide a standing part with a small amount of standing width P, and a standing part having a desired standing width P can be obtained by using a conventionally used side sheet.

以上、本発明の一実施形態について説明したが、本発明は上記の実施形態に限定されるものではない。 Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.

例えば、図５に示すように、上側サイドシート３２ｂにおいて、長手方向両端部近傍、及び長手方向中間部近傍の上側サイドシート３２ｂの部位をそれぞれ、下側サイドシート３２ｃと接合させて、長手方向に三カ所接合部位４１を形成し、長手方向一方側の接合部位を４１ａ、他方側の接合部位を４１ｂ、中途部の接合部位を４１ｃとし、その総称を接合部位４１とする。そして、接合部位４１ｃと、接合部位４１ｃと長手方向に隣接する接合部位４１ａ及び接合部位４１ｂとの間にはそれぞれ、上側サイドシート３２ｂと下側サイドシート３２ｃとで幅方向内方に開口したポケット部４２が形成されている。このようにポケット部４２を形成したことにより、使い捨て吸収性物品１を着用して横姿勢になったときに尿等を排泄したとしても、当該尿等はポケット部４２に一旦溜めてそのまま吸収性本体３の吸収材３１に吸収させることができる。つまり、ポケット部４２に尿等を留めて尿等の横漏れを防止する効果を奏することができる。また、ポケット部４２を構成している上側サイドシート３２ｂの部位の起立部３２１の起立幅も小さいので、着用し易く快適な着用性を確保することができる。なお、本実施形態では、二つのポケット部４２が接合部位４１ｃを挟んで並列した構成となっているが、各ポケット部４２を構成している上側サイドシート３２ｂの起立部の起立幅は共に長手方向に均一である。 For example, as shown in FIG. 5, in the upper side sheet 32b, the portions of the upper side sheet 32b in the vicinity of both ends in the longitudinal direction and in the vicinity of the middle part in the longitudinal direction are joined to the lower side sheet 32c in the longitudinal direction. Three joint portions 41 are formed. The joint portion on one side in the longitudinal direction is 41a, the joint portion on the other side is 41b, the joint portion in the middle is 41c, and the generic name is the joint portion 41. And between the junction part 41c and the junction part 41a and the junction part 41b which adjoin the junction part 41c in the longitudinal direction, the pocket opened in the width direction inner side by the upper side sheet 32b and the lower side sheet 32c, respectively. A portion 42 is formed. By forming the pocket portion 42 in this manner, even if the urine is excreted when the disposable absorbent article 1 is worn and placed in the lateral position, the urine etc. is temporarily stored in the pocket portion 42 and is absorbed as it is. It can be absorbed by the absorbent 31 of the main body 3. That is, an effect of preventing urine or the like from leaking by holding urine or the like in the pocket portion 42 can be achieved. Moreover, since the standing width | variety of the standing part 321 of the site | part of the upper side sheet | seat 32b which comprises the pocket part 42 is also small, it is easy to wear and comfortable wearability can be ensured. In the present embodiment, the two pocket portions 42 are arranged side by side with the joint portion 41c interposed therebetween. However, the standing widths of the standing side portions of the upper side sheet 32b constituting each pocket portion 42 are both long. Uniform in direction.

また、上記実施形態では、上側サイドシート３２ｂと、上側サイドシート３２ｂと対向する下側サイドシート３２ｃとの間に接着層４０を形成したが、上側サイドシート３２ｂと、上側サイドシート３２ｂと対向するトップシート３３との間にも接着層４０を形成してもよく、上側サイドシート３２ｂと、上側サイドシート３２ｂと対向する下側サイドシート３２ｃ及びトップシート３３との間にも接着層４０を形成してもよい。また、ポケット部４２の形成についても同様で、上側サイドシート３２ｂと、上側サイドシート３２と対向するトップシート３３とでポケット部４２を形成してもよい。 Moreover, in the said embodiment, although the contact bonding layer 40 was formed between the upper side sheet | seat 32b and the lower side sheet | seat 32c facing the upper side sheet | seat 32b, it opposes the upper side sheet | seat 32b and the upper side sheet | seat 32b. The adhesive layer 40 may also be formed between the top sheet 33 and the adhesive layer 40 may also be formed between the upper side sheet 32b, the lower side sheet 32c facing the upper side sheet 32b, and the top sheet 33. May be. The pocket portion 42 is formed in the same manner, and the pocket portion 42 may be formed by the upper side sheet 32 b and the top sheet 33 facing the upper side sheet 32.

また、上記実施形態では、サイドシート３２が二つ折りにされている場合について記載したが、サイドシート３２を二つ折りにせずに幅方向の寸法Ｑを有する接着層４０を形成することもできる。詳しくは、図６に示すように、サイドシート３２と、サイドシート３２と対向するトップシート３３との間に、サイドシート３２若しくはトップシート３３の幅方向両外端部から幅方向内側に所定の距離Ｑのところまでに長手方向にわたって幅方向の寸法が均一な接着層４０を形成させる。ここで、サイドシート３２において、接着層４０が形成されている部位を基部３２２、基部３２２より幅方向内側に位置する部位を起立部３２１とする。なお、起立部３２１とサイドシート３２との間には接着層は形成されておらず、起立部３２１の先端部はサイドシート３２の自由端部に相当する。また、サイドシート３２の外側端部近傍には、サイドシート３２のほぼ全長にわたって第２起立用弾性部材３９が長手方向に伸長した状態で取り付けられている。このような構成にすることで、起立部３２１の先端部近傍に取り付けられている第１起立用弾性部材３８の収縮により、起立部３２１は上方に立ち上がったひだ状の立体ギャザーとなる。なお、この実施形態では、折曲部３２ａを設けても設けなくてもどちらでもよい。折曲部３２ａを設けない場合は、図６に示すように、サイドシート３２とトップシート３３とを別部材で形成しておき、接着層４０で互いに接合させる構成にすることもできる。 Moreover, although the case where the side sheet 32 was folded in two was described in the above embodiment, the adhesive layer 40 having the dimension Q in the width direction can be formed without folding the side sheet 32 in half. Specifically, as shown in FIG. 6, a predetermined amount is provided between the side sheet 32 and the top sheet 33 facing the side sheet 32 from the width direction outer ends of the side sheet 32 or the top sheet 33 inward in the width direction. By the distance Q, the adhesive layer 40 having a uniform dimension in the width direction over the longitudinal direction is formed. Here, in the side sheet 32, a part where the adhesive layer 40 is formed is a base part 322, and a part located on the inner side in the width direction than the base part 322 is a standing part 321. Note that an adhesive layer is not formed between the standing portion 321 and the side sheet 32, and the leading end portion of the standing portion 321 corresponds to a free end portion of the side sheet 32. Further, the second standing elastic member 39 is attached to the vicinity of the outer end portion of the side seat 32 so as to extend in the longitudinal direction over almost the entire length of the side seat 32. With such a configuration, the upright portion 321 becomes a pleated three-dimensional gather that rises upward due to contraction of the first upright elastic member 38 attached in the vicinity of the distal end portion of the upright portion 321. In this embodiment, the bent portion 32a may or may not be provided. When the bent portion 32 a is not provided, as shown in FIG. 6, the side sheet 32 and the top sheet 33 may be formed as separate members and bonded to each other with the adhesive layer 40.

また、ポケット部４２の形成については、サイドシート３２と吸収性本体３のトップシート３３とで形成することもできる。詳しくは、図７に示すように、長手方向に延びるサイドシート３２において、長手方向両端部近傍、及び長手方向略中途部近傍のサイドシート３２の部位をそれぞれトップシート３３と接合して、長手方向に三カ所接合部位４１を形成し、長手方向一方側の接合部位を４１ａ、他方側の接合部位を４１ｂ、中途部の接合部位を４１ｃとし、その総称を接合部位４１とする。そして、接合部位４１ｃと長手方向に隣接する接合部位４１ａ及び接合部位４１ｂとの間にはそれぞれ、サイドシート３２とトップシート３３とで幅方向内方に開口したポケット部４２が形成されている。このようにポケット部４２を形成したことにより、使い捨て吸収性物品１を着用して横姿勢になったときに尿等を排泄したとしても、当該尿等はポケット部４２に一旦溜めてそのまま吸収性本体３の吸収材３１に吸収させることができる。つまり、ポケット部４２に尿等を留めて尿等の横漏れを防止する効果を奏することができる。また、ポケット部４２を構成しているサイドシート３２の部位の起立部３２１の起立幅も小さいので、着用し易く快適な着用性を確保することができる。なお、本実施形態では、接合部位を三カ所に設けてポケット部を二カ所に形成したが、更に多くの接合部位及びポケット部を形成してもよい。また、本実施形態でも、二つのポケット部４２が接合部位４１ｃを挟んで並列した構成となっているが、各ポケット部４２を構成しているサイドシート３２の起立部の起立幅は共に長手方向に均一である。 Further, the pocket portion 42 can be formed by the side sheet 32 and the top sheet 33 of the absorbent main body 3. Specifically, as shown in FIG. 7, in the side sheet 32 extending in the longitudinal direction, the portions of the side sheet 32 in the vicinity of both ends in the longitudinal direction and in the vicinity of the middle part in the longitudinal direction are joined to the top sheet 33, respectively. The joint part 41 is formed in three places, the joint part on one side in the longitudinal direction is 41a, the joint part on the other side is 41b, the joint part in the middle is 41c, and the generic name is the joint part 41. And the pocket part 42 opened in the width direction inner side by the side sheet | seat 32 and the top sheet 33 is formed between the junction part 41a and the junction part 41b adjacent to the junction part 41c in the longitudinal direction, respectively. By forming the pocket portion 42 in this manner, even if the urine is excreted when the disposable absorbent article 1 is worn and placed in the lateral position, the urine etc. is temporarily stored in the pocket portion 42 and is absorbed as it is. It can be absorbed by the absorbent 31 of the main body 3. That is, an effect of preventing urine or the like from leaking by holding urine or the like in the pocket portion 42 can be achieved. Moreover, since the standing width | variety of the standing part 321 of the site | part of the side seat | sheet 32 which comprises the pocket part 42 is also small, it is easy to wear and comfortable wearability can be ensured. In the present embodiment, the joint portions are provided at three locations and the pocket portions are formed at two locations, but more joint portions and pocket portions may be formed. Also in this embodiment, the two pocket portions 42 are arranged side by side with the joint portion 41c interposed therebetween, but the standing widths of the standing portions of the side seats 32 constituting each pocket portion 42 are both in the longitudinal direction. Is uniform.

また、上記実施形態では、脚周り用弾性部材２０と脚周り用弾性部材２１との間に、前後方向に所定の間隔を設けてその間に領域Ｃを設定していたが、当該所定の間隙がない構成にしてもよい。 In the above embodiment, a predetermined interval is provided in the front-rear direction between the leg-surrounding elastic member 20 and the leg-surrounding elastic member 21, and the region C is set therebetween. You may make it the structure which is not.

また、上記実施形態では、トップシート３３と別体に構成したサイドシート３２を吸収性本体３の幅方向両側端部に設けた構成について説明したが、サイドシート３２とトップシート３３とを実質的に一体の構成としてもよい。この場合、接着層４０を形成せずに幅方向の寸法が小さいサイドシートを用いることで起立部３２１の起立幅Ｐを微少量とすることもできる。 Moreover, although the said embodiment demonstrated the structure which provided the side sheet 32 comprised separately from the top sheet 33 in the width direction both ends of the absorptive main body 3, the side sheet 32 and the top sheet 33 are substantially made. It is good also as an integral structure. In this case, the standing width P of the standing portion 321 can be made very small by using a side sheet having a small width dimension without forming the adhesive layer 40.

なお、上記実施形態では、起立部３２１の起立幅Ｐを、立ち上がった状態での起立部３２１の先端部からトップシート３３の上面までの距離としたが、立ち上がった状態での起立部３２１の先端部から下側サイドシート３２ｃの上面までの距離を起立部の起立幅Ｐとしてもよい。また、図４及び図６では、接着層４０、５０、５１、５２、５３を厚みをもたせて図示しているが、これは分かりやすくするために誇張させたものであり実際はかなり薄い。したがって、立ち上がった状態での起立部３２１の先端部から下端部までの距離を起立部３２１の起立幅Ｐとすることもできる。 In the above embodiment, the standing width P of the standing portion 321 is the distance from the tip of the standing portion 321 to the top surface of the top sheet 33 in the standing state, but the tip of the standing portion 321 in the standing state. A distance from the upper part to the upper surface of the lower side seat 32c may be used as the standing width P of the standing part. 4 and 6, the adhesive layers 40, 50, 51, 52, and 53 are shown with a thickness, but this is exaggerated for the sake of clarity and is actually quite thin. Therefore, the distance from the tip end portion to the lower end portion of the standing portion 321 in the standing state can be set as the standing width P of the standing portion 321.

また、上記実施形態では、吸収性本体３を外側シート部材２に取り付けたパンツ型使い捨て吸収性物品１について説明したが、吸収性本体３単体を既存のおむつカバー等にテープで装着して使用したり、既存のパンツ型使い捨ておむつの吸収性本体の上に重ね置きする交換可能な尿パッドやナプキンとして使用することも可能である。 Moreover, in the said embodiment, although the underpants type disposable absorbent article 1 which attached the absorptive main body 3 to the outer sheet | seat member 2 was demonstrated, the absorptive main body 3 single-piece | unit is mounted | worn with an existing diaper cover etc. and used. Or it can also be used as an exchangeable urine pad or napkin that is placed on the absorbent main body of an existing pants-type disposable diaper.
