Description

本発明は、着用者からの排泄物を受ける吸収性物品に関する。   The present invention relates to an absorbent article that receives excrement from a wearer.

従来より、使い捨ておむつでは、少量の排尿時であってもおむつ全体を交換する必要があるため、使用者にとって経済的な負担が大きくなってしまう。そこで、使い捨ておむつの本体部上に安価な補助吸収具（いわゆる、尿パッド等）を取り付けて着用し、少量の排尿時には補助吸収具のみを交換することが行われている。   Conventionally, in a disposable diaper, since it is necessary to replace the entire diaper even when a small amount of urination is performed, an economical burden is increased for the user. Therefore, an inexpensive auxiliary absorbent device (so-called urine pad or the like) is attached to the main body of the disposable diaper and worn, and only the auxiliary absorbent device is replaced when urinating a small amount.

このように、補助吸収具を使用する場合、補助吸収具を着用者にとって適切な位置に装着して尿や便の漏出を防止する必要がある。例えば、特許文献１では、使い捨て紙おむつおよびインナーパッド（補助吸収具）の一部（例えば、中心線上や端部）に互いに対応する位置決め用目印を設けることにより、インナーパッドを使い捨て紙おむつの中央部に迅速かつ確実に装着するための技術が開示されている。
特開２００３−９３４３８号公報 Thus, when using an auxiliary | assistant absorption tool, it is necessary to mount | wear with an auxiliary | assistant absorption tool in a suitable position for a wearer, and to prevent the leakage of urine or feces. For example, in Patent Document 1, by disposing a positioning mark corresponding to a disposable paper diaper and a part of the inner pad (auxiliary absorbent) (for example, on the center line or an end), the inner pad is placed at the center of the disposable paper diaper. A technique for quickly and reliably mounting is disclosed.
JP 2003-93438 A

ところで、着用者の身体状況（例えば、半身麻痺や拘縮の状態、あるいは、男性器の使い捨ておむつ内の位置）によっては、使い捨ておむつ内で尿が流れる方向が偏る等、排泄傾向が偏るため、使い捨ておむつの中央部に補助吸収具を取り付けただけでは漏出を適切に防止することができない場合がある。   By the way, depending on the wearer's physical condition (for example, the state of hemiplegia or contracture, or the position of the male genital disposable diaper), the direction of urine flowing in the disposable diaper is biased, etc. Leakage may not be prevented properly by simply attaching an auxiliary absorbent device to the center of the disposable diaper.

このような場合には、着用者の身体状況に合わせて使い捨ておむつに対する補助吸収具の取付位置をずらすことが好ましい。しかしながら、特許文献１の使い捨て紙おむつでは、使い捨て紙おむつの中央部や端部にのみ目印が設けられているため、インナーパッドの微妙な位置調整をすることが困難である。また、専用の目印が設けられたインナーパッド以外の補助吸収具を利用する場合には、迅速な位置決め自体が困難になってしまう。   In such a case, it is preferable to shift the attachment position of the auxiliary absorbent with respect to the disposable diaper according to the wearer's physical condition. However, in the disposable paper diaper disclosed in Patent Document 1, it is difficult to finely adjust the position of the inner pad because the mark is provided only at the center or end of the disposable paper diaper. In addition, when an auxiliary absorbent tool other than the inner pad provided with a dedicated mark is used, quick positioning itself becomes difficult.

図１は、本発明の第１の実施の形態に係る吸収性物品１を示す平面図である。着用者からの排泄物を受ける吸収性物品１は、着用者の腹側に当接する部位と背側に当接する部位とを腰回りで止着して着用するオープンタイプの使い捨ておむつ等として利用される。   FIG. 1 is a plan view showing an absorbent article 1 according to the first embodiment of the present invention. The absorbent article 1 that receives excrement from the wearer is used as an open-type disposable diaper that is worn around the waist around a part that abuts on the abdomen and a part that abuts on the back. The

図１に示すように、吸収性物品１は、略シート状の本体部２、本体部２の長手方向（すなわち、図１中のＹ方向）のほぼ全長に亘って、本体部２の長手方向に垂直な幅方向の両側（すなわち、（＋Ｘ）側および（−Ｘ）側）に設けられた一対の側壁部３、並びに、本体部２の長手方向の一方の端部（（−Ｙ）側の端部であり、着用者の背側に当接する部位）において幅方向の両側に取り付けられた一対の止着部２４を備える。吸収性物品１の着用時には、本体部２の（＋Ｚ）側の主面が着用者に接する面となり、一対の止着部２４のそれぞれに２つ設けられた面ファスナー２４１により、止着部２４が本体部２の（＋Ｙ）側の端部（すなわち、着用者の腹側に当接する部位）の着用者側とは反対側に止着される。   As shown in FIG. 1, the absorbent article 1 includes a substantially sheet-like main body 2 and the longitudinal direction of the main body 2 over almost the entire length in the longitudinal direction of the main body 2 (that is, the Y direction in FIG. 1). And a pair of side wall portions 3 provided on both sides in the width direction perpendicular to (i.e., (+ X) side and (-X) side), and one end portion ((-Y) side in the longitudinal direction of the main body portion 2 And a pair of fastening portions 24 attached to both sides in the width direction at a portion contacting the back side of the wearer). When the absorbent article 1 is worn, the main surface on the (+ Z) side of the main body 2 becomes a surface in contact with the wearer, and the fastening portion 24 is provided by two hook-and-loop fasteners 241 provided on each of the pair of fastening portions 24. Is fastened to the side opposite to the wearer side of the end portion on the (+ Y) side of the main body portion 2 (that is, the portion that contacts the abdomen side of the wearer).

一対の側壁部３のそれぞれには、Ｙ方向に伸びる複数の弾性部材３１ａ，３１ｂが接合されており、図１に示すように吸収性物品１を広げた状態では、弾性部材３１ａ，３１ｂは伸張状態となっている。吸収性物品１では、内側の弾性部材３１ａが収縮することにより、本体部２の側方において側壁部３の内側のエッジが着用者側に向かって立ち上がり、外側の弾性部材３１ｂが収縮することにより、側壁部３の外側のエッジおよび下側のシートが着用者側かつ内側に向かって立ち上がって着用時に着用者の足の付け根近傍に当接する立体ギャザー（いわゆる、レッグギャザー）が形成される。側壁部３は、撥水性または不透液性の不織布（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）やプラスチックフィルム、あるいは、これらの複合材料により形成される。吸収性物品１の快適性向上の観点からは、側壁部３は通気性を有することが好ましい。   A plurality of elastic members 31a and 31b extending in the Y direction are joined to each of the pair of side wall portions 3, and when the absorbent article 1 is expanded as shown in FIG. 1, the elastic members 31a and 31b are stretched. It is in a state. In the absorbent article 1, when the inner elastic member 31 a contracts, the inner edge of the side wall 3 rises toward the wearer side on the side of the main body 2, and the outer elastic member 31 b contracts. A solid gather (so-called leg gather) is formed in which the outer edge and the lower sheet of the side wall portion 3 rise toward the wearer side and inward and abut on the vicinity of the base of the wearer's foot when worn. The side wall 3 is formed of a water-repellent or liquid-impervious nonwoven fabric (for example, a spunbond nonwoven fabric, a meltblown nonwoven fabric, an SMS (spunbond / meltblown / spunbond) nonwoven fabric), a plastic film, or a composite material thereof. . From the viewpoint of improving the comfort of the absorbent article 1, the side wall portion 3 preferably has air permeability.

図２は、吸収性物品１をおよそ中央でＹ方向に垂直な面で切断した断面図である。図１および図２に示すように、本体部２は、吸液性の吸収コア２２、吸収コア２２の着用者側（すなわち、（＋Ｚ）側）の主面を覆うトップシート２１、および、吸収コア２２のもう一方の主面を覆うバックシート２３を備え、吸収コア２２の側方には側壁部３が接合される。トップシート２１とバックシート２３とは、ホットメルト接着剤等により吸収コア２２の周囲にて接合される。吸収性物品１では、トップシート２１の着用者側においてインナーパッド等の略矩形の補助吸収具９が図１および図２中に二点鎖線にて示すように取り付け可能とされる。   FIG. 2 is a cross-sectional view of the absorbent article 1 cut along a plane approximately in the center and perpendicular to the Y direction. As shown in FIGS. 1 and 2, the main body 2 includes a liquid-absorbing absorbent core 22, a top sheet 21 that covers the main surface of the absorbent core 22 on the wearer side (that is, the (+ Z) side), and an absorbent body. A back sheet 23 that covers the other main surface of the core 22 is provided, and the side wall 3 is joined to the side of the absorbent core 22. The top sheet 21 and the back sheet 23 are joined around the absorbent core 22 by a hot melt adhesive or the like. In the absorbent article 1, a substantially rectangular auxiliary absorbent 9 such as an inner pad can be attached on the wearer side of the top sheet 21 as shown by a two-dot chain line in FIGS. 1 and 2.

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、スパンレース不織布であり、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）により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 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 spunlace nonwoven fabrics. As hydrophilic fibers forming these nonwoven fabrics, cellulose, rayon, cotton, or the like is usually used. 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 an active agent may be used. A plastic film having holes 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。親水性繊維を包むティッシュペーパー等は、親水性繊維の型崩れ、および、吸水性ポリマーの脱落を防止する。   The absorbent core 22 is obtained by wrapping a hydrophilic fiber (for example, pulverized pulp fiber or cellulose fiber) mixed with a granular water-absorbing polymer (for example, SAP (Super Absorbent Polymer)) with tissue paper or a liquid-permeable sheet. The moisture formed and absorbed through the top sheet 21 is quickly fixed. Tissue paper or the like that wraps hydrophilic fibers prevents the hydrophilic fibers from being deformed and the water-absorbing polymer from falling off.

バックシート２３は撥水性または不透液性の不織布であり、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、本体部２の外側（すなわち、（−Ｚ）側）にしみ出すのを防止する。バックシート２３として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。なお、撥水性または不透液性のプラスチックフィルムや、上記不織布とプラスチックフィルムとの複合材料等がバックシート２３として利用されてもよい。この場合、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利用されることが好ましい。   The back sheet 23 is a water-repellent or liquid-impervious nonwoven fabric, and the moisture that has permeated through the top sheet 21 and the moisture once absorbed by the absorbent core 22 are outside the main body 2 (that is, the (−Z) side). ) Prevent exudation. Nonwoven fabrics used as the back sheet 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. A water-repellent or liquid-impervious plastic film, a composite material of the nonwoven fabric and the plastic film, or the like may be used as the back sheet 23. In this case, from the viewpoint of the wearer's comfort, it is preferable to use a plastic film having air permeability.

図１に示すように、トップシート２１は、本体部２の長手方向および幅方向に伸びる線４１にて形成される格子状の位置決めパターン４を備え、位置決めパターン４の複数の線４１は、互いに略平行に、約５〜１０ｍｍの間隔をあけて配列される。位置決めパターン４の線４１は、長手方向および幅方向に関して一定個数毎（本実施の形態では、５つ毎）に異なる線４１ａ（本実施の形態では、線４１よりも太い線である。）とされる。位置決めパターン４は、吸収性物品１の製造時にインラインにて印刷によりトップシート２１の吸収コア２２側の面に形成されており、本体部２の長手方向および幅方向に対する補助吸収具９の取付位置の特定に利用される。なお、位置決めパターン４は、トップシート２１の着用者側の面に印刷されてもよい。また、位置決めパターン４は、吸収性物品１を広げた状態における（倒れた状態の）側壁部３の下側のトップシート２１上にも形成されてよい。   As shown in FIG. 1, the top sheet 21 includes a lattice-shaped positioning pattern 4 formed by lines 41 extending in the longitudinal direction and the width direction of the main body 2, and the plurality of lines 41 of the positioning pattern 4 are mutually connected. They are arranged approximately parallel with an interval of about 5 to 10 mm. The line 41 of the positioning pattern 4 is different from the line 41a (in the present embodiment, thicker than the line 41) by a certain number (in this embodiment, every five) in the longitudinal direction and the width direction. Is done. The positioning pattern 4 is formed on the surface of the top sheet 21 on the side of the absorbent core 22 by in-line printing when the absorbent article 1 is manufactured, and the attachment position of the auxiliary absorbent 9 in the longitudinal direction and the width direction of the main body 2. Used to identify The positioning pattern 4 may be printed on the surface of the top sheet 21 on the wearer side. The positioning pattern 4 may also be formed on the top sheet 21 below the side wall 3 in a state in which the absorbent article 1 is expanded (in a collapsed state).

吸収性物品１が着用される際には、まず、吸収性物品１に補助吸収具９が取り付けられ、その後、補助吸収具９と共に吸収性物品１が着用者にあてがわれて止着部２４により止着される。吸収性物品１に補助吸収具９が取り付けられる際には、前回使用された補助吸収具９の使用後の状態（すなわち、補助吸収具９のどの部位を中心として尿等が吸収されているか等）から着用者の排泄傾向が把握された上で、必要に応じて前回の取付位置からずらしながら補助吸収具９の各コーナー部を線４１，４１ａの交点に重ね合わせたり、補助吸収具９のエッジを位置決めパターン４の線４１または線４１ａに沿わせる等して、位置決めパターン４に基づいて補助吸収具９の取り付けが行われる。例えば、排泄が着用者の腹側かつ右側に偏っている場合には、補助吸収具９は、前回の取付位置よりも図１中の（＋Ｘ）側かつ（＋Ｙ）側にずらして取り付けられる。   When the absorbent article 1 is worn, first, the auxiliary absorbent 9 is attached to the absorbent article 1, and then the absorbent article 1 is applied to the wearer together with the auxiliary absorbent 9 and the fastening portion 24. It is fixed by. When the auxiliary absorbent 9 is attached to the absorbent article 1, the state after use of the previously used auxiliary absorbent 9 (that is, which part of the auxiliary absorbent 9 is mainly used to absorb urine etc.) ), The wearer's excretion tendency is grasped, and each corner portion of the auxiliary absorbent device 9 is overlapped with the intersection of the lines 41 and 41a while shifting from the previous mounting position as necessary. The auxiliary absorbent 9 is attached based on the positioning pattern 4 by, for example, aligning the edge with the line 41 or the line 41 a of the positioning pattern 4. For example, when excretion is biased to the wearer's stomach side and right side, the auxiliary absorbent 9 is attached to the (+ X) side and (+ Y) side in FIG.

以上に説明したように、吸収性物品１では、トップシート２１に格子状の位置決めパターン４が設けられることにより、着用者の排泄傾向に適合する補助吸収具９の取付位置を容易に特定することができる。その結果、補助吸収具９の交換時において、補助吸収具９の吸収性物品１に対する位置決めを容易に行い、同じ大きさの補助吸収具９を吸収性物品１上の同一または適切に変更された取付位置に取り付けることができる。また、複数の介護者により交代で補助吸収具９の交換が行われる場合には、補助吸収具９の適切な取付位置に関する情報（例えば、右側から１番目の線４１と腹側から１１番目の線４１との交点に補助吸収具９の１つのコーナー部を合わせて取り付ける、といった情報。）を他の介護者に正確に伝達することができる。   As explained above, in the absorbent article 1, the grid-like positioning pattern 4 is provided on the top sheet 21, thereby easily specifying the mounting position of the auxiliary absorbent 9 that matches the excretion tendency of the wearer. Can do. As a result, when the auxiliary absorbent 9 was replaced, the auxiliary absorbent 9 was easily positioned with respect to the absorbent article 1, and the same size of the auxiliary absorbent 9 was changed to the same or appropriately on the absorbent article 1. It can be attached to the attachment position. Further, when the auxiliary absorbent device 9 is exchanged by a plurality of caregivers in turn, information on an appropriate mounting position of the auxiliary absorbent device 9 (for example, the first line 41 from the right side and the eleventh line from the ventral side). The information that one corner portion of the auxiliary absorbent 9 is attached to the intersection with 41 can be accurately transmitted to other caregivers.

なお、吸収性物品１が着用される際には、まず、補助吸収具９が着用者の適切な着用部位にあてがわれ、その後、補助吸収具９の上から吸収性物品１が着用されてもよい。このような場合であっても、吸収性物品１では、本体部２の長手方向の端部まで位置決めパターン４が設けられているため、吸収性物品１に対する補助吸収具９の相対的な取付位置を、着用者の排泄傾向に適合するように容易に特定することができる。   In addition, when the absorbent article 1 is worn, first, the auxiliary absorbent device 9 is applied to an appropriate wearing part of the wearer, and then the absorbent article 1 is worn over the auxiliary absorbent device 9. Also good. Even in such a case, in the absorbent article 1, the positioning pattern 4 is provided up to the end in the longitudinal direction of the main body 2, so the relative attachment position of the auxiliary absorbent 9 with respect to the absorbent article 1. Can be easily identified to fit the wearer's excretion tendency.

吸収性物品１では、位置決めパターン４において、一定個数の線４１毎に太さの異なる線４１ａが設けられるため、補助吸収具９の取付位置の特定をより容易に行うことができる。また、位置決めパターン４がトップシート２１に印刷により形成されるため、位置決めパターン４を容易に設けることができる。   In the absorbent article 1, in the positioning pattern 4, the line 41 a having a different thickness is provided for each fixed number of lines 41, so that the attachment position of the auxiliary absorbent 9 can be specified more easily. Further, since the positioning pattern 4 is formed on the top sheet 21 by printing, the positioning pattern 4 can be easily provided.

図３は、本発明の第２の実施の形態に係る吸収性物品１ａを示す平面図である。吸収性物品１ａでは、本体部２の長手方向および幅方向に等間隔に広がる格子点のパターンである位置決めパターン４ａが、トップシート２１の吸収コア２２側に塗布された有色ホットメルト接着剤により形成される。その他の構成は図１と同様であり、以下の説明において同符号を付す。   FIG. 3 is a plan view showing an absorbent article 1a according to the second embodiment of the present invention. In the absorbent article 1a, the positioning pattern 4a, which is a pattern of lattice points extending at equal intervals in the longitudinal direction and the width direction of the main body 2, is formed by a colored hot melt adhesive applied to the absorbent core 22 side of the top sheet 21. Is done. Other configurations are the same as those in FIG. 1, and the same reference numerals are given in the following description.

位置決めパターン４ａの点４２は、長手方向および幅方向に関して約５〜１０ｍｍの間隔をあけて配列され、一定個数毎（本実施の形態では、５つ毎）に異なる点４２ａ（本実施の形態では、点４２よりも大きい点である。）とされる。本体部２が形成される際には、トップシート２１の吸収コア２２側の面に有色ホットメルト接着剤が格子点状に塗布され、吸収コア２２を間に挟んでトップシート２１とバックシート２３とが接着される。   The points 42 of the positioning pattern 4a are arranged with an interval of about 5 to 10 mm in the longitudinal direction and the width direction, and different points 42a (in this embodiment, every five) in a certain number (in this embodiment). , A point larger than the point 42). When the main body 2 is formed, a colored hot-melt adhesive is applied to the surface of the top sheet 21 on the side of the absorbent core 22 in the form of lattice dots, and the top sheet 21 and the back sheet 23 with the absorbent core 22 interposed therebetween. Are glued together.

吸収性物品１ａでは、着用者の排泄傾向に合わせ、補助吸収具９の各コーナー部やエッジを位置決めパターン４ａの点４２または点４２ａに重ね合わせる等して、位置決めパターン４ａに基づいて補助吸収具９が取り付けられる。   In the absorbent article 1a, in accordance with the wearer's excretion tendency, the auxiliary absorbent device 9 is supplemented based on the positioning pattern 4a by superimposing each corner or edge of the auxiliary absorbent device 9 on the point 42 or the point 42a of the positioning pattern 4a. 9 is attached.

以上に説明したように、吸収性物品１ａでは、トップシート２１、吸収コア２２およびバックシート２３の接着、並びに、位置決めパターン４ａの形成を同一工程にて行うことにより、吸収性物品１ａの製造を簡素化することができる。なお、トップシート２１、吸収コア２２およびバックシート２３の接着には、位置決めパターン４ａの形成に用いられたホットメルト接着剤以外の他の接着剤が併用されてもよい。   As described above, in the absorbent article 1a, the absorbent article 1a is manufactured by bonding the top sheet 21, the absorbent core 22 and the back sheet 23 and forming the positioning pattern 4a in the same process. It can be simplified. For bonding the top sheet 21, the absorbent core 22, and the back sheet 23, an adhesive other than the hot melt adhesive used for forming the positioning pattern 4a may be used in combination.

吸収性物品１ａでは、第１の実施の形態と同様に、位置決めパターン４ａに基づいて補助吸収具９の取り付けが行われるため、着用者の排泄傾向に適合する補助吸収具９の取付位置を容易に特定することができる。また、位置決めパターン４ａにおいて、一定個数の点４２毎に大きさの異なる点４２ａが設けられるため、補助吸収具９の取付位置の特定をより容易に行うことができる。   In the absorbent article 1a, as in the first embodiment, the auxiliary absorbent device 9 is attached based on the positioning pattern 4a. Therefore, the attachment position of the auxiliary absorbent device 9 that fits the wearer's excretion tendency is easy. Can be specified. Further, in the positioning pattern 4a, the point 42a having a different size is provided for each fixed number of points 42, so that the attachment position of the auxiliary absorbent 9 can be specified more easily.

図４は、本発明の第３の実施の形態に係る吸収性物品１ｂを示す平面図である。吸収性物品１ｂの位置決めパターン４ｂは、第２の実施の形態と同様に、本体部２の長手方向および幅方向に広がる格子点のパターンとされ、位置決めパターン４ｂを形成する点４２は、長手方向および幅方向に関して一定個数毎に異なる点４２ａとされる。吸収性物品１ｂでは、位置決めパターン４ｂの（＋Ｘ）側かつ（−Ｙ）側の部位（すなわち、着用者の背側かつ右側に接する部位）における点４２，４２ａの密度が、他の部位における点４２，４２ａの密度よりも高い。以下、位置決めパターン４ｂにおいて点４２，４２ａの密度が高い部位を、「高密度部位４３」という。   FIG. 4 is a plan view showing an absorbent article 1b according to the third embodiment of the present invention. As in the second embodiment, the positioning pattern 4b of the absorbent article 1b is a pattern of lattice points extending in the longitudinal direction and the width direction of the main body 2, and the points 42 forming the positioning pattern 4b are in the longitudinal direction. Further, the points 42a are different for every certain number in the width direction. In the absorbent article 1b, the density of the points 42 and 42a in the (+ X) side and (−Y) side portions of the positioning pattern 4b (that is, the portion in contact with the wearer's back side and the right side) is the point in other portions. It is higher than the density of 42 and 42a. Hereinafter, the part where the density of the points 42 and 42a is high in the positioning pattern 4b is referred to as a “high density part 43”.

吸収性物品１ｂは、排泄が背側かつ右側に偏る傾向を有する着用者により利用され、補助吸収具９が、本体部２の略中央から図４中の（＋Ｘ）側かつ（−Ｙ）側、すなわち、高密度部位４３側にずらして配置されて取り付けられる。吸収性物品１ｂでは、着用者の排泄傾向に合わせて、着用者の背側かつ右側に対応する補助吸収具９のコーナー部の位置決めを精度良く行うことができ、微妙な調整も可能となる。また、点４２の粗密により、吸収性物品１の交換を行う介護者が、補助吸収具９の取付位置をどちら側にずらすべきかを速やかに把握することもできる。   The absorbent article 1b is used by a wearer whose excretion tends to be biased to the back side and the right side, and the auxiliary absorbent 9 is located on the (+ X) side and (−Y) side in FIG. In other words, they are attached by being shifted to the high density portion 43 side. In the absorbent article 1b, the corner portions of the auxiliary absorbent device 9 corresponding to the back side and the right side of the wearer can be accurately positioned in accordance with the wearer's excretion tendency, and delicate adjustment is also possible. Further, due to the density of the points 42, the caregiver who replaces the absorbent article 1 can quickly grasp to which side the attachment position of the auxiliary absorbent 9 should be shifted.

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.

例えば、図１では、位置決めパターン４の線４１，４１ａが実線とされているが、線４１，４１ａは破線や点線等のように実質的に線とみなすことができるものであってもよい。また、図３に示す点４２，４２ａについても同様に、実質的に点とみなすことができるものであれば、例えば、四角形や菱形、星印等であってもよい。さらには、吸収性物品の位置決めパターンは、本体部２に対する補助吸収具９の取付位置の特定に利用できる他の様々な形状の図形の集合であってもよい。   For example, in FIG. 1, the lines 41 and 41a of the positioning pattern 4 are solid lines, but the lines 41 and 41a may be substantially regarded as lines such as a broken line or a dotted line. Similarly, the points 42 and 42a shown in FIG. 3 may be squares, diamonds, stars, or the like as long as they can be substantially regarded as points. Furthermore, the positioning pattern of the absorbent article may be a set of figures of various other shapes that can be used for specifying the attachment position of the auxiliary absorbent 9 with respect to the main body 2.

第３の実施の形態に係る吸収性物品１ｂでは、高密度部位４３は、使用者に合わせて位置決めパターン４ｂの他の部位に設けられてもよく、また、位置決めパターン４ｂ中に複数の高密度部位４３が設けられてもよい。図５は、パンツタイプの吸収性物品１ｃを伸ばした状態で着用者側の面を示す平面図である。図５に示すように、吸収性物品１ｃでは、位置決めパターン４ｃの（＋Ｘ）側かつ（−Ｙ）側に向かって、線４１，４１ａの密度が漸次高くなるように位置決めパターン４ｃが形成される。吸収性物品１ｃでは、図４の場合と同様に、線４１，４１ａが高密度に設けられた部位上において、補助吸収具９のコーナー部（あるいは、エッジ）の位置を高精度に調整して位置決めすることができる。このように、位置決めパターンの少なくとも一部における線や点の密度が、他の一部における密度よりも高くされることにより、着用者の排泄傾向に合わせて補助吸収具９の特定の部位の位置決めを精度良く行うことができる。   In the absorbent article 1b according to the third embodiment, the high-density portion 43 may be provided in other portions of the positioning pattern 4b according to the user, and a plurality of high-density portions are included in the positioning pattern 4b. The part 43 may be provided. FIG. 5 is a plan view showing a surface on the wearer side in a state where the pant-type absorbent article 1c is stretched. As shown in FIG. 5, in the absorbent article 1c, the positioning pattern 4c is formed so that the density of the lines 41 and 41a gradually increases toward the (+ X) side and the (-Y) side of the positioning pattern 4c. . In the absorbent article 1c, as in the case of FIG. 4, the position of the corner portion (or edge) of the auxiliary absorbent 9 is adjusted with high accuracy on the portion where the lines 41, 41a are provided at high density. Can be positioned. As described above, the density of the line or point in at least a part of the positioning pattern is made higher than the density in the other part, thereby positioning a specific part of the auxiliary absorbent device 9 according to the excretion tendency of the wearer. It can be performed with high accuracy.
