Description

本発明は、パンツ型吸収性物品に関する。 The present invention relates to a pants-type absorbent article.

従来、吸収性物品の一例としてパンツ型使い捨てが知られている。例えば、特許文献1には、前胴回り域11、後胴回り域12、及び吸収構造体21を有する使い捨ておむつ10が開示されている。特許文献1に示す使い捨ておむつ10では、吸収体22に幅方向の長さが短い括れ部分を形成して、吸収体22が乳幼児の脚の動きを制限してしまう恐れを軽減させている。 Conventionally, pants-type disposable products are known as an example of absorbent articles. For example, Patent Document 1 discloses a disposable diaper 10 having a front waist circumference region 11, a rear waist circumference region 12, and an absorption structure 21. In the disposable diaper 10 shown in Patent Document 1, a constricted portion having a short width in the width direction is formed in the absorber 22 to reduce the possibility that the absorber 22 restricts the movement of the infant's legs.

特開2017-12459号公報Japanese Unexamined Patent Publication No. 2017-12459

しかし、特許文献1のような使い捨ておむつ10においては、吸収体22の幅方向の長さが短くなっているため、幅方向の剛性が低下してしまう。そのため、乳幼児が脚を閉じると、幅方向の外側から内側に向かって吸収体22が押し潰されると、乳幼児の脚と脚の間の吸収構造体21及び吸収体11を持て余した状態となりやすく、外観上、もっさりとした印象を与える恐れがある。 However, in the disposable diaper 10 as in Patent Document 1, since the length of the absorber 22 in the width direction is short, the rigidity in the width direction is lowered. Therefore, when the infant closes the legs, when the absorber 22 is crushed from the outside to the inside in the width direction, the absorption structure 21 and the absorber 11 between the legs of the infant are likely to be left over. There is a risk of giving a light impression on the appearance.

本発明は、上記のような問題に鑑みてなされたものであって、外観上すっきりとした印象を与えやすい使い捨ておむつを提供することを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a disposable diaper that easily gives a clean impression in appearance.

The absorbent core is folded in half and has a front core portion located on the front side and a rear core portion located on the rear side, and the absorbent core has a shorter length in the left-right direction than the upper portion. The ventral waist circumference portion and the dorsal waist circumference portion have a narrow portion, and each of the waist circumference expansion / contraction member has the waist circumference expansion / contraction member that expands and contracts in the left-right direction. In the extended state, the vertical length of the narrow portion in the front core portion is longer than the vertical length of the narrow portion in the rear core portion, and the narrow portion of the front core portion. Is a pants-type absorbent article characterized by having at least one squeezed portion having a predetermined length in the left-right direction.

このようなパンツ型吸収性物品によれば、着用者である乳幼児の脚の可動性を確保するために前側コア部に幅狭部を設けた場合であっても、左右方向からの力が集中しやすい幅狭部に圧搾部を設けて、左右方向の剛性を向上させることで、使い捨ておむつの外観をすっきりとさせやすくなる。 According to such a pants-type absorbent article, even when a narrow portion is provided in the front core portion in order to secure the mobility of the leg of the infant who is the wearer, the force from the left-right direction is concentrated. By providing a squeezing part in the narrow part that is easy to do and improving the rigidity in the left-right direction, it becomes easy to make the appearance of the disposable diaper neat.

かかるパンツ型吸収性物品であって、前記幅狭部は、複数の前記圧搾部を有することが望ましい。 In such a pants-type absorbent article, it is desirable that the narrow portion has a plurality of the squeezed portions.

このようなパンツ型吸収性物品によれば、吸収性コアの幅狭部の左右方向の剛性をより向上させることができる。 According to such a pants-type absorbent article, the rigidity of the narrow portion of the absorbent core in the left-right direction can be further improved.

かかるパンツ型吸収性物品であって、前記後側コア部は、少なくとも1つの前記圧搾部を有しており、前記前側コア部には、前記圧搾部のうちの、ある圧搾部が設けられており、前記後側コア部には、前記圧搾部のうちの、他の圧搾部が設けられており、前記伸長状態において、前記ある圧搾部と前記他の圧搾部は前記左右方向の長さが同じであり、前記前側コア部において、前記ある圧搾部の前記左右方向の端は、前記前側コア部の端に接しており、前記後側コア部において、前記他の圧搾部の前記左右方向の端は、前記後側コア部の端に接していないことが望ましい。 In such a pants-type absorbent article, the posterior core portion has at least one squeezed portion, and the front core portion is provided with a squeezed portion of the squeezed portions. The posterior core portion is provided with another squeezing portion of the squeezing portions, and in the extended state, the squeezing portion and the other squeezing portions have lengths in the left-right direction. The same is true, in the front core portion, the left-right end of the one squeezed portion is in contact with the end of the front core portion, and in the rear core portion, the left-right end of the other squeezed portion. It is desirable that the end does not touch the end of the posterior core portion.

このようなパンツ型吸収性物品によれば、前側コア部は、左右方向の長さが短いことで着用者の脚を動かしやすくしつつ、左右方向の剛性を高めて、前側コア部が前後方向に膨らむ恐れをより軽減させることができる。一方、後側コア部は、圧搾部の左右方向の外側に、圧搾されていない剛性が低い領域を有するため、剛性の低い領域は、臀部の形状に沿いやすくなり、***物が左右方向の外側に漏れる恐れを軽減させることができる。 According to such a pants-type absorbent article, the front core portion has a short length in the left-right direction, which makes it easier for the wearer's legs to move, while increasing the rigidity in the left-right direction, so that the front core portion is in the front-rear direction. The risk of swelling can be further reduced. On the other hand, since the rear core portion has a region with low rigidity that is not squeezed on the outside in the left-right direction of the squeezed portion, the region with low rigidity tends to follow the shape of the buttocks, and excrement is on the outside in the left-right direction. It is possible to reduce the risk of leakage to.

かかるパンツ型吸収性物品であって、前記幅狭部は、前記左右方向の長さが最も短い最狭部を有し、前記後側コア部は、少なくとも1つの前記圧搾部を有し、前記後側コア部の前記圧搾部の前記左右方向の長さは、前記最狭部の前記左右方向の長さ以上であることが望ましい。 In such a pants-type absorbent article, the narrow portion has the narrowest portion having the shortest length in the left-right direction, and the rear core portion has at least one of the squeezed portions. It is desirable that the length of the squeezed portion of the rear core portion in the left-right direction is equal to or greater than the length of the narrowest portion in the left-right direction.

かかるパンツ型吸収性物品であって、前記吸収性コアを備えた吸収性本体を有し、前記吸収性本体は、防漏壁伸縮部材、肌側に起立不能な固定部、及び肌側に起立可能な起立部を備えた一対の防漏壁を有し、前記圧搾部の前記左右方向の長さは、前記防漏壁の前記左右方向の内側の端同士の距離よりも長いことが望ましい。 Such a pants-type absorbent article having an absorbent body provided with the absorbent core, the absorbent body having a leak-proof wall elastic member, a fixing portion that cannot stand on the skin side, and standing on the skin side. It is desirable to have a pair of leak-proof walls with possible upright portions, the left-right length of the squeezed portion being longer than the distance between the left-right inner ends of the leak-proof wall.

このようなパンツ型吸収性物品によれば、圧搾部の左右方向の長さが防漏壁の左右方向の内側の端同士の距離よりも短い場合よりも吸収性コアの剛性を向上させることができる。 According to such a pants-type absorbent article, the rigidity of the absorbent core can be improved as compared with the case where the length of the squeezed portion in the left-right direction is shorter than the distance between the inner ends in the left-right direction of the leak-proof wall. can.

かかるパンツ型吸収性物品であって、前記前側コア部は、複数の前記圧搾部を有し、複数の前記圧搾部のうち、最も下側に位置する下側圧搾部と、前記下側圧搾部に上側から隣接する隣接下側圧搾部との間隔は、前記腹側胴回り部の下端よりも下側に設けられた複数の前記圧搾部のうち、最も上側に位置する上側圧搾部と、前記上側圧搾部に下側から隣接する隣接上側圧搾部との間隔よりも小さいことが望ましい。 In such a pants-type absorbent article, the front core portion has a plurality of the squeezed portions, and among the plurality of the squeezed portions, the lower squeezed portion located at the lowermost side and the lower squeezed portion. The distance between the upper side and the adjacent lower side squeezing part is such that the upper side squeezing part located on the uppermost side and the upper side of the plurality of squeezing parts provided below the lower end of the ventral waist circumference portion. It is desirable that the distance from the lower side to the adjacent upper side squeezing part is smaller than that of the squeezing part.

このようなパンツ型吸収性物品によれば、前側コア部の腹側胴回り部により近い領域は、前側コア部が前側に膨らむ恐れが低いため、圧搾部をより少なく設け、前側コアの下側は、前側コア部が前側に膨らむ恐れがより高いため、圧搾部を設けて、左右方向の剛性を向上させて、前側に膨らむ恐れを軽減させることができる。 According to such a pants-type absorbent article, in the region closer to the ventral waistline portion of the front core portion, the front core portion is less likely to bulge toward the front side, so that the compression portion is provided less, and the lower side of the front core portion is provided. Since the front core portion is more likely to bulge to the front side, it is possible to provide a squeezing portion to improve the rigidity in the left-right direction and reduce the risk of bulging to the front side.

<<< Basic configuration of pants-type disposable diapers >>>
FIG. 1A is a schematic perspective view of a pants-type disposable diaper 1. FIG. 1B is a diagram showing an example of a wearing state of the diaper 1. FIG. 2 is a schematic plan view of the unfolded and stretched diaper 1 as viewed from the side surface of the skin. FIG. 3 is a schematic cross-sectional view shown by arrow AA in FIG. FIG. 4 is a schematic cross-sectional view shown by arrow BB in FIG. The "deployed state" means that the joints between the side portions 20a of the ventral waist circumference 20 and the side portions 30a of the dorsal waist circumference 30 on both sides of the diaper 1 are separated and opened to open the entire diaper 1 in a plane. It is in the expanded state. The "extended state" indicates a state in which the elastic member included in the diaper 1 is extended to the extent that the wrinkles of the diaper 1 cannot be visually recognized. Specifically, it shows a state in which the dimensions of each member constituting the diaper 1 (for example, the ventral waist circumference portion 20 to be described later) are extended until the dimensions match or are close to the dimensions of the member alone. The CC line in FIG. 2 is the center line in the left-right direction. In FIG. 3, the adhesive is omitted for convenience.

図1に示すように、パンツ型のおむつ1は上下方向と左右方向と前後方向とを有し、おむつ1には胴回り開口部BH及び一対の脚回り開口部LHが形成されている。上下方向において、胴回り開口部BH側を上側とし、着用者の股下となる側を下側とする。図2の状態(展開かつ伸長状態)のおむつ1の上下方向を「長手方向」、長手方向の一方側を「腹側」、他方側を「背側」ともいい、長手方向における中央部C10側を「下側」ともいう。前後方向において、着用者の腹側となる側を前側とし、着用者の背側となる側を後側とする。また、おむつ1は図3に示すように厚さ方向を有し、厚さ方向において着用者に接触する側を肌側とし、その逆側を非肌側とする。 As shown in FIG. 1, the pants-type diaper 1 has a vertical direction, a horizontal direction, and a front-rear direction, and the diaper 1 is formed with a waist circumference opening BH and a pair of leg circumference openings LH. In the vertical direction, the waist opening BH side is the upper side, and the inseam side of the wearer is the lower side. The vertical direction of the diaper 1 in the state of FIG. 2 (expanded and extended state) is also referred to as "longitudinal direction", one side in the longitudinal direction is also referred to as "ventral side", and the other side is also referred to as "dorsal side". Is also called "lower side". In the anterior-posterior direction, the ventral side of the wearer is the front side, and the dorsal side of the wearer is the posterior side. Further, the diaper 1 has a thickness direction as shown in FIG. 3, and the side in the thickness direction in contact with the wearer is the skin side, and the opposite side is the non-skin side.

おむつ1は、所謂3ピースタイプであり、吸収性本体10と腹側胴回り部20、背側胴回り部30とを有する。腹側胴回り部20は、着用者の腹側を覆い、背側胴回り部30は、着用者の背側を覆う。吸収性本体10は平面視略長方形形状である。図3に示すように、吸収性本体10の腹側の上端部と背側の上端部は、それぞれ胴回り部20、30の肌側面と重ね合されている。腹側胴回り部20、背側胴回り部30は平面視略長方形状であり、その長手方向が左右方向に沿っている。 The diaper 1 is a so-called three-piece type, and has an absorbent main body 10, a ventral waist circumference portion 20, and a dorsal waist circumference portion 30. The ventral waistline 20 covers the wearer's ventral side, and the dorsal waistline 30 covers the wearer's dorsal side. The absorbent body 10 has a substantially rectangular shape in a plan view. As shown in FIG. 3, the ventral upper end portion and the dorsal upper end portion of the absorbent body 10 are overlapped with the skin side surfaces of the waist circumference portions 20 and 30, respectively. The ventral waist circumference portion 20 and the dorsal waist circumference portion 30 have a substantially rectangular shape in a plan view, and their longitudinal directions are along the left-right direction.

図2の展開状態にて示されるように、おむつ1は、中心線C-Cに対して左右対称な形状を有している。吸収性本体10の腹側の上端部、及び背側の上端部のそれぞれ非肌側面と胴回り部20、30の肌側面とを接着剤等(不図示)により接合し、図2に示す展開状態から、腹側胴回り部20と背側胴回り部30とが対向するように吸収性本体10を中央部C10で二つ折りし、腹側胴回り部20の左右方向の両側部20aと背側胴回り部30の左右方向の両側部30aとを接合することにより、おむつ1はパンツ型となる。 As shown in the unfolded state of FIG. 2, the diaper 1 has a shape symmetrical with respect to the center line CC. The non-skin side surface of the ventral upper end portion and the dorsal upper end portion of the absorbent body 10 and the skin side surface of the waist circumference portions 20 and 30, respectively, are joined by an adhesive or the like (not shown), and the unfolded state shown in FIG. Then, the absorbent main body 10 is folded in half at the central portion C10 so that the ventral waist circumference portion 20 and the dorsal waist circumference portion 30 face each other, and both side portions 20a and the dorsal waist circumference portion 30 in the left-right direction of the ventral waist circumference portion 20. By joining the left and right side portions 30a of the diaper 1, the diaper 1 becomes a pants type.

腹側胴回り部20及び背側胴回り部30はそれぞれ、不織布等の柔軟な肌側シート21、31と非肌側シート22、32と、胴回り伸縮部材23、33とを備える。胴回り伸縮部材23、33によって、腹側胴回り部20及び背側胴回り部30は伸縮可能となり、着用者の胴回りにフィットする。肌側シート21、31及び非肌側シート22、32は、各シート単体としては、左右方向に伸縮性を実質的に有さない非伸縮シートである。肌側シート21、31及び非肌側シート22、32としては、SMS不織布(スパンボンド・メルトブローン・スパンボンド不織布)、スパンボンド不織布、エアスルー不織布、プラスチックシート、開孔プラスチックシート及びそれらのラミネートシート等を用いることができる。 The ventral waist circumference portion 20 and the dorsal waist circumference portion 30 are provided with flexible skin-side sheets 21 and 31 such as non-woven fabric, non-skin-side sheets 22 and 32, and waist circumference expansion and contraction members 23 and 33, respectively. The waist circumference telescopic members 23 and 33 allow the ventral waist circumference portion 20 and the dorsal waist circumference portion 30 to expand and contract, and fit the wearer's waist circumference. The skin-side sheets 21 and 31 and the non-skin-side sheets 22 and 32 are non-stretchable sheets that do not substantially have elasticity in the left-right direction as a single sheet. Examples of the skin-side sheets 21 and 31 and the non-skin-side sheets 22 and 32 include SMS non-woven fabric (spunbond, meltblown, spunbond non-woven fabric), spunbond non-woven fabric, air-through non-woven fabric, plastic sheet, perforated plastic sheet and their laminated sheets. Can be used.

腹側胴回り伸縮部材23は、左右に伸縮する複数の糸ゴム23aと上下及び左右方向に伸縮する伸縮シート23bである。糸ゴム23aは、肌側シート21と非肌側シート22との間で、且つ、腹側胴回り部20の上端部を除く全域に上下方向に間隔を空けて、左右方向に伸長した状態で固定されている。伸縮シート23bは、非肌側から肌側に折り返された非肌側シート22と肌側シート21との間で、吸収性本体10よりも非肌側に配置され、且つ、腹側胴回り部20の上端部に、左右方向に伸長した状態で固定されている。伸縮シート23bは、弾性を有する熱可塑性エラストマー性繊維であるポリウレタン系エラストマーと、非弾性を有する熱可塑性樹脂性繊維であるポリオレフィン系樹脂のポリプロピレン(PP)とを有する、ギア延伸等の適宜な延伸処理が施された不織布やプラスチック製の伸縮性を有するフィルムシート等である。 The ventral waist circumference telescopic member 23 is a plurality of thread rubbers 23a that expand and contract left and right and an elastic sheet 23b that expands and contracts in the vertical and horizontal directions. The thread rubber 23a is fixed between the skin side sheet 21 and the non-skin side sheet 22 in a state of being extended in the left-right direction with a vertical interval in the entire area except the upper end portion of the ventral waist circumference portion 20. Has been done. The elastic sheet 23b is arranged between the non-skin side sheet 22 folded back from the non-skin side to the skin side and the skin side sheet 21 on the non-skin side of the absorbent main body 10, and the ventral waist circumference portion 20. It is fixed to the upper end of the tongue in a state of being extended in the left-right direction. The elastic sheet 23b has a polyurethane-based elastomer which is a thermoplastic elastomer fiber having elasticity and polypropylene (PP) which is a polyolefin-based resin which is a thermoplastic resin fiber having inelasticity, and is appropriately stretched by gear stretching or the like. It is a treated non-woven fabric, a plastic elastic film sheet, or the like.

このように、腹側胴回り部20の上端部に糸ゴム23aを配置せずに伸縮シート23bを配置することで、腹側胴回り部20の上端部が面で着用者にフィットする。そのため、腹部の局所的な締め付けを抑え、腹側胴回り伸縮部材23によって肌に締め付けた跡が残り難くすることができる。特に、乳幼児の腹部は、背側に比べて前にせり出しているため、腹側胴回り20が局所的に締め付けてしまう恐れを軽減することがより好ましい。 In this way, by arranging the elastic sheet 23b without arranging the thread rubber 23a on the upper end portion of the ventral waist circumference portion 20, the upper end portion of the ventral waist circumference portion 20 fits the wearer on the surface. Therefore, the local tightening of the abdomen can be suppressed, and the trace of tightening on the skin can be made difficult to remain by the ventral waist circumference expansion / contraction member 23. In particular, since the abdomen of the infant protrudes forward as compared with the dorsal side, it is more preferable to reduce the possibility that the ventral waist circumference 20 is locally tightened.

背側胴回り伸縮部材23は、背側胴回り部30の上端部から下端部に亘って上下方向に間隔を空けて配された、左右方向に伸縮する複数の糸ゴム33であり、肌側シート31と非肌側シート32との間に左右方向に伸長した状態で固定されている。 The dorsal waist circumference elastic member 23 is a plurality of thread rubbers 33 that expand and contract in the left-right direction and are arranged at intervals in the vertical direction from the upper end portion to the lower end portion of the dorsal waist circumference portion 30, and is a skin-side sheet 31. And the non-skin side sheet 32 are fixed in a state of being extended in the left-right direction.

なお、腹側胴回り部20及び背側胴回り部30は、それぞれ腹側胴回り伸縮部材23及び背側胴回り伸縮部材33とともに伸縮する伸縮領域Df、Dbと、腹側胴回り伸縮部材23及び背側胴回り伸縮部材33とともに伸縮しない非伸縮領域Ff、Fbを有する。図8は、伸縮領域Df、Dbと非伸縮領域Ff、Fbを説明する図である。図8において、右斜め下のハッチングで伸縮領域Df、Dbを示し、左斜め下のハッチングで非伸縮領域Ff、Fbを示している。非伸縮領域Ff、Fbは、腹側胴回り部20及び背側胴回り部30のそれぞれ左右方向の中央部で、吸収性コア11Aと前後方向で重なる領域に設けられている。非伸縮領域Ff、Fbを設けることで、伸縮部材23、33の収縮によって吸収性コア11Aが左右方向に縮められて変形してしまう恐れを軽減している。 The ventral waist circumference portion 20 and the dorsal waist circumference portion 30 have expansion and contraction regions Df and Db that expand and contract together with the ventral waist circumference expansion and contraction member 23 and the dorsal waist circumference expansion and contraction member 33, respectively, and the ventral waist circumference expansion and contraction member 23 and the dorsal waist circumference expansion and contraction member 23. It has non-expandable regions Ff and Fb that do not expand and contract together with the member 33. FIG. 8 is a diagram illustrating the stretchable regions Df and Db and the non-stretchable regions Ff and Fb. In FIG. 8, the hatching on the lower right side shows the telescopic areas Df and Db, and the hatching on the lower left side shows the non-stretchable areas Ff and Fb. The non-stretchable regions Ff and Fb are provided in the central portion in the left-right direction of the ventral waist circumference portion 20 and the dorsal waist circumference portion 30, respectively, in a region overlapping the absorbent core 11A in the front-rear direction. By providing the non-stretchable regions Ff and Fb, the possibility that the absorbent core 11A is shrunk and deformed in the left-right direction due to the shrinkage of the stretchable members 23 and 33 is reduced.

図4は、図2中のB-B矢視で示す概略断面図である。図4は、厚さ方向に関して構成を理解しやすいように寸法を適宜変更して示している。図4に示すように、吸収性本体10は、厚さ方向の肌側から順に、一対の防漏壁部材15、トップシート12、吸収体11と、バックシート13、外装シート14とを備え、それぞれホットメルト等の接着剤によって接着されている。トップシート12は液透過性シートであればよく、親水性のエアスルー不織布やスパンボンド不織布等を例示できる。バックシート13は液不透過性シートであればよく、ポリエチレンフィルムやポリプロピレンフィルム、疎水性のSMS不織布等を例示できる。トップシート12及びバックシート13は吸収体11全体を覆う大きさとする。防漏壁部材15及び外装シート14は、液透過性シートでも液不透過性シートでもよく、疎水性のSMS不織布等を例示できる。ただし、本実施形態では防漏壁部材15及び外装シート14によって防漏壁部50及びレッグギャザー部60がそれぞれ形成されるため、防漏壁部材15及び外装シート14は液不透過性の素材で構成されることが好ましい。 FIG. 4 is a schematic cross-sectional view shown by arrow BB in FIG. FIG. 4 shows the dimensions appropriately changed so that the configuration can be easily understood in the thickness direction. As shown in FIG. 4, the absorbent main body 10 includes a pair of leak-proof wall members 15, a top sheet 12, an absorber 11, a back sheet 13, and an exterior sheet 14 in order from the skin side in the thickness direction. Each is bonded with an adhesive such as hot melt. The top sheet 12 may be a liquid permeable sheet, and examples thereof include hydrophilic air-through non-woven fabrics and spunbonded non-woven fabrics. The back sheet 13 may be a liquid-impermeable sheet, and examples thereof include a polyethylene film, a polypropylene film, and a hydrophobic SMS non-woven fabric. The top sheet 12 and the back sheet 13 have a size that covers the entire absorber 11. The leak-proof wall member 15 and the exterior sheet 14 may be a liquid-permeable sheet or a liquid-impermeable sheet, and examples thereof include hydrophobic SMS non-woven fabrics. However, in the present embodiment, the leak-proof wall member 15 and the exterior sheet 14 form the leak-proof wall portion 50 and the leg gather portion 60, respectively, so that the leak-proof wall member 15 and the exterior sheet 14 are made of a liquid-impermeable material. It is preferably configured.

一対の防漏壁部材15は、一対の防漏壁部50を構成する。一対の防漏壁部50は、所謂立体ギャザーであり、吸収性本体10の長手方向に沿って、吸収体11の左右方向の両側部に設けられている。具体的には、複数の防漏壁伸縮部材51を内側に挟んだ状態で二つ折りされた防漏壁部材15の折り目部分を左右方向の内側に配置し、吸収性本体10の左右方向の側端から吸収体11の左右方向の側部に重ね合される位置まで設けている。 The pair of leak-proof wall members 15 constitutes a pair of leak-proof wall portions 50. The pair of leak-proof wall portions 50 are so-called three-dimensional gathers, and are provided on both sides of the absorber 11 in the left-right direction along the longitudinal direction of the absorbent body 10. Specifically, the crease portion of the leak-proof wall member 15 folded in half with the plurality of leak-proof wall expansion / contraction members 51 sandwiched inside is arranged inside in the left-right direction, and the side of the absorbent body 10 in the left-right direction. It is provided from the end to a position where it is overlapped with the side portion of the absorber 11 in the left-right direction.

図6は、図2の概略平面図の構成を説明する概略図である。なお、図6では、便宜上、図2の概略平面図から胴回り伸縮部材23、33やスリットS等を省略して示している。一対の防漏壁部50は、外装シート14やトップシート12に防漏壁部材15を接合する一対のエンド接合部52と一対のサイド接合部53と、長手方向(上下方向)に伸縮する複数の防漏壁伸縮部材51を備え、肌側に起立不能な一対の固定部55、55と、肌側に起立可能な一対の起立部56を備える。防漏壁部50のうち、腹側胴回り部20の側の上端からエンド接合部52の下端まで、及び背側胴回り部30の側の上端からエンド接合部52の下端までの各領域が固定部55である。そして、防漏壁部50のうち、腹側胴回り部20の側におけるエンド接合部52の下端より下側で、且つ、背側胴回り部30の側におけるエンド接合部52の下端より下側の領域が起立部56である。この防漏壁部50によって横流れした***物が堰き止められる。 FIG. 6 is a schematic view illustrating the configuration of the schematic plan view of FIG. Note that, for convenience, FIG. 6 shows the waistline expansion / contraction members 23, 33, slits S, and the like omitted from the schematic plan view of FIG. The pair of leak-proof wall portions 50 includes a pair of end joint portions 52 and a pair of side joint portions 53 for joining the leak-proof wall member 15 to the exterior sheet 14 and the top sheet 12, and a plurality of portions that expand and contract in the longitudinal direction (vertical direction). The leak-proof wall expansion / contraction member 51 is provided, and a pair of fixing portions 55 and 55 that cannot stand on the skin side and a pair of standing portions 56 that can stand on the skin side are provided. Of the leak-proof wall portion 50, each region from the upper end on the ventral waist circumference 20 side to the lower end of the end joint 52 and from the upper end on the dorsal waist circumference 30 side to the lower end of the end joint 52 is a fixed portion. It is 55. Then, in the leak-proof wall portion 50, a region below the lower end of the end joint portion 52 on the side of the ventral waist circumference portion 20 and below the lower end of the end joint portion 52 on the side of the dorsal waist circumference portion 30. Is the standing portion 56. The leak-proof wall 50 blocks the excrement that has flowed sideways.

一対のエンド接合部52及び一対のサイド接合部53は、ホットメルト接着剤等の接着剤で接合している部分である。なお、エンド接合部52及びサイド接合部53の接合は、接着剤による固定に限らず、圧搾や圧着等により固定を行ってもよい。 The pair of end joints 52 and the pair of side joints 53 are portions that are bonded with an adhesive such as a hot melt adhesive. The joint of the end joint portion 52 and the side joint portion 53 is not limited to fixing with an adhesive, but may be fixed by pressing, crimping, or the like.

一対のエンド接合部52は、吸収性本体10の長手方向の両端部に配置されており、固定部55を肌側に起立不能とするための「接着部」である。エンド接合部52は、長手方向において、吸収性本体10の端から吸収体11の上側端部に重なる位置まで設けられている。一対のサイド接合部53は、吸収性本体10の長手方向の一端から他端まで設けられているものと吸収性本体10の腹側の端から長手方向の中央部C10まで設けられているものとがある。それぞれエンド接合部52よりも左右方向の外側に配置されている。 The pair of end joints 52 are arranged at both ends of the absorbent body 10 in the longitudinal direction, and are "adhesive portions" for making the fixed portion 55 unable to stand on the skin side. The end joint portion 52 is provided from the end of the absorbent body 10 to a position overlapping the upper end of the absorbent body 11 in the longitudinal direction. The pair of side joints 53 are provided from one end to the other end of the absorbent body 10 in the longitudinal direction and one provided from the ventral end of the absorbent body 10 to the central portion C10 in the longitudinal direction. There is. Each is arranged outside the end joint portion 52 in the left-right direction.

防漏壁部50は、防漏壁伸縮部材51の収縮によって、サイド接合部53に左右方向内側から隣接する部分を基点に起立部56が肌側に起立可能となる。なお、複数本の防漏壁伸縮部材51をそれぞれ離間させて設けることで、防漏壁部50の起立状態では、着用者の肌に防漏壁部50を面で接触させやすくなり、肌触りを向上させることができる。 The leak-proof wall portion 50 can stand up on the skin side with the portion adjacent to the side joint portion 53 from the inside in the left-right direction as a base point due to the contraction of the leak-proof wall expansion / contraction member 51. By providing the plurality of leak-proof wall expansion / contraction members 51 apart from each other, it becomes easier for the leak-proof wall portion 50 to come into contact with the wearer's skin on the surface in the upright state of the leak-proof wall portion 50, and the skin feels soft. Can be improved.

外装シート14は、脚回り伸縮部材16を備えた一対のレッグギャザー部60を構成する。レッグギャザー部60は、脚回り開口部LHを形成する部分であり、脚回り伸縮部材16の収縮により着用者の脚にフィットする。 The exterior sheet 14 constitutes a pair of leg gather portions 60 provided with a leg-rotating telescopic member 16. The leg gather portion 60 is a portion that forms the leg circumference opening LH, and fits the wearer's leg by contraction of the leg circumference expansion / contraction member 16.

左右方向の両端部が内側に折り返されており、折り返された外装シート14同士の間に脚回り伸縮部材16を配置して、レッグギャザー部60を構成する。脚回り伸縮部材16は、長手方向に沿った複数本の糸ゴムであり、左右方向の内側に折り返されて2層となった外装シート14の間に、吸収性本体10の長手方向に伸長された状態で固定されている。 Both ends in the left-right direction are folded inward, and the leg-rotating elastic member 16 is arranged between the folded exterior sheets 14 to form the leg gather portion 60. The leg rotation elastic member 16 is a plurality of thread rubbers along the longitudinal direction, and is extended in the longitudinal direction of the absorbent body 10 between the exterior sheets 14 which are folded inward in the left-right direction to form two layers. It is fixed in the state of being fixed.

脚回り伸縮部材16として糸ゴムを用いる場合、複数本配置することが好ましく、より好ましくは5本以上配置することがよい。図2等においては、8本の脚回り伸縮部材16を左右方向に並べて配置している。仮に脚回り伸縮部材16が1本の場合には、着用者の脚を局所的に締め付けてしまう恐れがあるが、脚回り伸縮部材16をより多く設けることで、レッグギャザー部60は全体的に面でフィットしやすくなり、着用者の脚を局所的に締め付けてしまう恐れを軽減させることができる。 When a thread rubber is used as the leg circumference expansion / contraction member 16, a plurality of rubber threads are preferably arranged, and more preferably five or more are arranged. In FIG. 2 and the like, eight leg-circling expansion / contraction members 16 are arranged side by side in the left-right direction. If there is only one leg circumference telescopic member 16, there is a risk that the wearer's legs will be locally tightened. However, by providing more leg circumference telescopic members 16, the leg gather portion 60 can be used as a whole. It is easier to fit on the surface and the risk of locally tightening the wearer's legs can be reduced.

吸収体11は、平面視略矩形形状であり、尿等の液体を吸収して保持する吸収性コア11Aと、吸収性コア11Aの外周面を被覆するコアラップシート11Bとを備える。図5は、吸収体11を説明する図である。コアラップシート11Bとしては、ティッシュペーパーや不織布等の液透過性シートを例示できる。図5において、便宜上、コアラップシート11Bに覆われた吸収性コア11Aを実線で示している。 The absorber 11 has a substantially rectangular shape in a plan view, and includes an absorbent core 11A that absorbs and holds a liquid such as urine, and a core wrap sheet 11B that covers the outer peripheral surface of the absorbent core 11A. FIG. 5 is a diagram illustrating the absorber 11. As the core wrap sheet 11B, a liquid permeable sheet such as tissue paper or non-woven fabric can be exemplified. In FIG. 5, for convenience, the absorbent core 11A covered with the core wrap sheet 11B is shown by a solid line.

吸収性コア11Aは、高吸収性ポリマー(SAP)を含むパルプ等の液体吸収性繊維を略砂時計形状に成形されたものである。本実施形態において、吸収性コア11Aの液体吸収性繊維の坪量は、吸収性コア11A全域において略均一である。吸収性コア11Aのうち、中央部C10より腹側(前側)に位置する部分は前側コア部11Afであり、中央部C10より背側(後側)に位置する部分は後側コア部11Abである。後側コア部11Abに、厚さ方向(前後方向)に貫通したスリットSを備えることで、吸収性コア11Aが着用者のお尻の形状に沿いやすくしている。 The absorbent core 11A is formed by molding a liquid absorbent fiber such as pulp containing a highly absorbent polymer (SAP) into a substantially hourglass shape. In the present embodiment, the basis weight of the liquid absorbent fiber of the absorbent core 11A is substantially uniform over the entire area of the absorbent core 11A. Of the absorbent core 11A, the portion located ventrally (anterior) from the central portion C10 is the anterior core portion 11Af, and the portion located on the dorsal side (rear side) from the central portion C10 is the posterior core portion 11Ab. .. By providing the rear core portion 11Ab with a slit S penetrating in the thickness direction (front-back direction), the absorbent core 11A can easily follow the shape of the wearer's buttocks.

図5等に示すように、吸収性コア11Aの長手方向の中央部を左右方向の長さを短くし、くびれさせている。具体的には、前側コア部11Afの上部11fuより下側に前側幅狭部(「幅狭部」ともいう。)11fnと、後側コア部11Abの上部11buより下側に後側幅狭部11bnを設けている。前側幅狭部11fnの長手方向の長さは、後側幅狭部11bnの長手方向の長さよりも長い。また、吸収性コア11Aの左右方向の長さが一番短い部分である最狭部11nは、前側コア部11Afの幅狭部11fnに設けられている。前側幅狭部11fnの上下方向の長さは、後側幅狭部11bnの上下方向の長さよりも長い。 As shown in FIG. 5 and the like, the central portion of the absorbent core 11A in the longitudinal direction is constricted by shortening the length in the left-right direction. Specifically, the front narrow portion (also referred to as “narrow portion”) 11fn is below the upper 11fu of the front core portion 11Af, and the rear narrow portion is below the upper 11bu of the rear core portion 11Ab. 11 bn is provided. The length of the front narrow portion 11fn in the longitudinal direction is longer than the length of the rear narrow portion 11bn in the longitudinal direction. Further, the narrowest portion 11n, which is the portion having the shortest length in the left-right direction of the absorbent core 11A, is provided in the narrow portion 11fn of the front core portion 11Af. The vertical length of the front narrow portion 11fn is longer than the vertical length of the rear narrow portion 11bn.

通常、乳幼児は脚を前に出した姿勢でいることが多いため、比較的剛性が高い吸収体11が乳幼児の脚の動きを阻害する恐れを軽減させることを目的として、図5に示すように、吸収性コア11Aの、前側幅狭部11fnの上下方向の長さを、後側幅狭部11bnの上下方向の長さよりも長く設けている。前側幅狭部11fn、後側幅狭部11bnは、乳幼児の脚の動きによって、左右方向の力を受けやすい部分であり、特に、乳幼児が脚を左右方向の内側に閉じた場合には、前側幅狭部11fnに左右方向からの力が集中しやすい。そのため、前側幅狭部11fnに左右方向からの力が加えられると、図1Aに示す、吸収性本体10の中央領域Mが、くしゃくしゃとなるような変形を生じやすい。つまり、前側幅狭部11fnが前後方向に凹凸を有するような形状に変形しやすくなる。変形した状態の吸収性コア11及び吸収性本体10は、おむつ1の正面から見るともっさりとした印象を与えてしまうという問題があった。 Since infants are usually in a posture in which their legs are extended forward, as shown in FIG. 5, the purpose is to reduce the risk that the relatively rigid absorber 11 impedes the movement of the infant's legs. The vertical length of the front narrow portion 11fn of the absorbent core 11A is longer than the vertical length of the rear narrow portion 11bn. The front narrow portion 11fn and the posterior narrow portion 11bn are portions that are susceptible to left-right force due to the movement of the infant's legs, and particularly when the infant closes the legs inward in the left-right direction, the anterior side. Forces from the left and right directions are likely to be concentrated on the narrow portion 11fn. Therefore, when a force from the left-right direction is applied to the front side narrow portion 11fn, the central region M of the absorbent main body 10 shown in FIG. 1A is likely to be deformed to be crumpled. That is, the front narrow portion 11fn is likely to be deformed into a shape having irregularities in the front-rear direction. There is a problem that the absorbent core 11 and the absorbent main body 10 in the deformed state give a light impression when viewed from the front of the diaper 1.

この問題を解決すべく、おむつ1には吸収性コア11Aに圧搾部Eを設けている。以下、圧搾部Eについて説明する。 In order to solve this problem, the diaper 1 is provided with a pressing portion E in the absorbent core 11A. Hereinafter, the pressing unit E will be described.

===圧搾部E===
圧搾部Eは、複数の突部を有する凸ローラー(不図示)と、表面が平らなアンビルローラー(不図示)とのあいだのロール間隙に、加工前の吸収性コア11Aを通して、吸収性コアの非肌側から圧搾加工を行うことにより形成される。図7Aは、伸長状態のおむつ1を腹側から見た概略正面図である。図7Bは、図7A中のX-X矢視で示す領域における吸収性コア11Aの概略断面図である。吸収性コア11Aのうち、圧搾加工を行っていない領域は、非圧搾部Uである。
=== Squeezed part E ===
The squeezed portion E is formed by passing the unprocessed absorbent core 11A through the roll gap between the convex roller having a plurality of protrusions (not shown) and the flat surface anvil roller (not shown). It is formed by pressing from the non-skin side. FIG. 7A is a schematic front view of the stretched diaper 1 as viewed from the ventral side. FIG. 7B is a schematic cross-sectional view of the absorbent core 11A in the region shown by arrow XX in FIG. 7A. The region of the absorbent core 11A that has not been squeezed is the non-squeezed portion U.

圧搾部Eは、圧搾によって形成された溝であり、非圧搾部Uよりもパルプ等の液体吸収性繊維の密度が高く、非圧搾部Uよりも剛性が高い。本実施形態において、圧搾部Eの溝の深さは略均一である。溝の深さによって、液体吸収性繊維の密度が変化し、溝が深いほど液体吸収性繊維の密度が高くなり、溝が浅いほど液体吸収性繊維の密度が低くなる。図5等に示すように、圧搾部Eは左右方向に沿った形状であり、左右方向の長さWeは70mm、圧搾部Eの上下方向の長さDeは3mmであり、圧搾部Eは上下方向に等間隔に配置されており、上下方向に隣接する圧搾部E同士の間隔Duは10mmである。また、圧搾部Eの左右方向の中央は、吸収性コア11Aの中央であり、吸収性コア11Aは左右対称な形状である。 The squeezed portion E is a groove formed by squeezing, and has a higher density of liquid-absorbing fibers such as pulp than the non-squeezed portion U and a higher rigidity than the non-squeezed portion U. In the present embodiment, the depth of the groove of the squeezed portion E is substantially uniform. The density of the liquid-absorbing fiber changes depending on the depth of the groove. The deeper the groove, the higher the density of the liquid-absorbing fiber, and the shallower the groove, the lower the density of the liquid-absorbing fiber. As shown in FIG. 5 and the like, the squeezed portion E has a shape along the left-right direction, the length We in the left-right direction is 70 mm, the vertical length De of the squeezed portion E is 3 mm, and the squeezed portion E is up and down. It is arranged at equal intervals in the direction, and the interval Du between the pressing portions E adjacent to each other in the vertical direction is 10 mm. Further, the center of the squeezed portion E in the left-right direction is the center of the absorbent core 11A, and the absorbent core 11A has a symmetrical shape.

非圧搾部Uは、圧搾部Eよりも厚みが大きい。そのため、吸収性コア11Aは、非肌側面に凸部と凹部を有することが好ましい。図7Bに示すように、吸収性コア11Aは、肌側面は概ね平らであり、非肌側面に凸部と凹部を有する。凸部が非圧搾部Uであり、凹部が圧搾部Eである。このようにすることで、パンツ型のおむつ1の吸収性コア11Aの肌側を内側にして、長手方向の中央部で二つ折りにした際に、吸収性コア11Aの肌側面で吸収性コア11Aの凸部と凹部が干渉し合って吸収性コア11Aを曲がりにくくなるのを防ぐことができる。また、肌側面を概ね平らにすることで、着用者に吸収性コア11Aの凸凹や剛性の高い圧搾部Eによる違和感を生じさせる恐れを軽減させることができる。 The non-squeezed portion U is thicker than the squeezed portion E. Therefore, it is preferable that the absorbent core 11A has a convex portion and a concave portion on the non-skin side surface. As shown in FIG. 7B, the absorbent core 11A has a generally flat skin side surface and has protrusions and recesses on the non-skin side surface. The convex portion is the non-squeezed portion U, and the concave portion is the compressed portion E. By doing so, when the skin side of the absorbent core 11A of the pants-type diaper 1 is turned inside and the absorbent core 11A is folded in half at the central portion in the longitudinal direction, the absorbent core 11A is formed on the skin side surface of the absorbent core 11A. It is possible to prevent the convex portion and the concave portion of the absorbent core 11A from interfering with each other and making it difficult to bend the absorbent core 11A. Further, by making the side surface of the skin substantially flat, it is possible to reduce the risk of causing the wearer to feel uncomfortable due to the unevenness of the absorbent core 11A and the highly rigid pressing portion E.

図5等に示すように、上下方向の長さが、後側幅狭部11fbよりも長い前側幅狭部11fnに、左右方向に所定の長さを有する圧搾部Eを設けて、剛性が高い圧搾部Eによって、前側幅狭部11fnの左右方向の剛性を高めている。このようにすることで、前側幅狭部11fnの左右方向の剛性が増し、吸収性コア11Aの左右方向の平面形状を維持しやすくなる。 As shown in FIG. 5 and the like, the front side narrow portion 11fn having a length in the vertical direction longer than the rear side narrow portion 11fb is provided with a squeezing portion E having a predetermined length in the left-right direction to have high rigidity. The pressing portion E enhances the rigidity of the front narrow portion 11fn in the left-right direction. By doing so, the rigidity of the front narrow portion 11fn in the left-right direction is increased, and it becomes easy to maintain the planar shape of the absorbent core 11A in the left-right direction.

このように、脚を前に出した状態の乳幼児の脚の可動性を確保するために、前側幅狭部11fbの上下方向の長さを後側幅狭部11fbの上下方向の長さよりも長くした場合であっても、前側幅狭部11fbに集中しやすい左右方向の力に対して、前側コア部11Afの左右方向の剛性を高めて、前側コア部11Afの変形を軽減させることができる。つまり、圧搾部Eを設けることで、前側コア部11Afをより平面形状に維持しやすくなる。そのため、乳幼児の脚と脚の間の吸収性コア11及び吸収性本体10がくしゃくしゃな状態になる恐れを軽減して、おむつ1を正面から見た際の外観をすっきりとさせることができる。おむつ1の外観がすっきりすると、乳幼児はおむつ1によって動きを阻害される恐れを軽減するため、より活動的になったり、吸収性本体10が大きくみえることを防ぐことから、おむつ1内に貯留した***物の量を判断しやすくなり、おむつ1の交換を適切な時期に行いやすくなる。また、左右方向の剛性を高くした吸収性コア11Aは左右方向の平面形状を維持しやすくなるため、乳幼児の脚が閉じられて、吸収性本体10内の***物を収容する空間が縮められた場合でも、乳幼児が脚を開くと吸収性コア11Aによって吸収性本体10が元の状態に戻りやすくなり、吸収性本体10内の***物を収容する空間を確保しやすくなる。おむつ1内に***物を貯留する空間を確保することで、***物がおむつ1から漏れてしまう恐れを軽減させることができる。 In this way, in order to ensure the mobility of the infant's leg with the leg extended forward, the vertical length of the front narrow portion 11fb is longer than the vertical length of the rear narrow portion 11fb. Even in this case, the rigidity of the front core portion 11Af in the left-right direction can be increased with respect to the force in the left-right direction that tends to be concentrated on the front narrow portion 11fb, and the deformation of the front core portion 11Af can be reduced. That is, by providing the pressing portion E, it becomes easier to maintain the front core portion 11Af in a more planar shape. Therefore, it is possible to reduce the risk that the absorbent core 11 and the absorbent main body 10 between the legs of the baby will be in a crumpled state, and the appearance of the diaper 1 when viewed from the front can be made clear. When the appearance of the diaper 1 is refreshed, infants are stored in the diaper 1 because they are less likely to be hindered by the diaper 1 and become more active or prevent the absorbent body 10 from appearing large. It becomes easier to judge the amount of excrement, and it becomes easier to change the diaper 1 at an appropriate time. Further, since the absorbent core 11A having increased rigidity in the left-right direction can easily maintain the planar shape in the left-right direction, the legs of the infant are closed and the space for accommodating excrement in the absorbent body 10 is shortened. Even in this case, when the infant opens his / her legs, the absorbent core 11A makes it easier for the absorbent body 10 to return to its original state, and it becomes easier to secure a space for accommodating excrement in the absorbent body 10. By securing a space for storing excrement in the diaper 1, it is possible to reduce the risk of excrement leaking from the diaper 1.

なお、圧搾部Eを、前側コア部11Afには、前側幅狭部11fnに、少なくとも1つ設けることで、前側幅狭部11fnの剛性を増すことができ、おむつ1の外観をすっきりとさせやすくなる。ただし、図2等に示すように、複数の圧搾部Eを上下方向に並べて配置することがより好ましい。これによって、左右方向の剛性をより高めることができる。 By providing at least one pressing portion E in the front core portion 11Af and the front narrow portion 11fn, the rigidity of the front narrow portion 11fn can be increased, and the appearance of the diaper 1 can be easily made clean. Become. However, as shown in FIG. 2 and the like, it is more preferable to arrange the plurality of squeezed portions E side by side in the vertical direction. This makes it possible to further increase the rigidity in the left-right direction.

さらに、図2等に示すように、圧搾部Eを上下方向に等間隔に配置することが好ましい。上下方向に等間隔に配置された圧搾部Eによって、吸収性コア11Aに上下方向に均等な剛性を付与することができるため、吸収性コア11Aが偏った変形してしまう恐れを軽減させやすくなる。 Further, as shown in FIG. 2 and the like, it is preferable to arrange the squeezed portions E at equal intervals in the vertical direction. Since the squeezing portions E arranged at equal intervals in the vertical direction can impart uniform rigidity in the vertical direction to the absorbent core 11A, it is easy to reduce the risk of the absorbent core 11A being deformed unevenly. ..

同様に、圧搾部Eの左右方向の中央を吸収性コア11Aの左右方向の中央で、且つ吸収性本体10の左右方向の中央に設けることで、着用者の動きに対して、吸収性コア11Aが左右方向について偏った変形をしてしまう恐れを軽減することができる。 Similarly, by providing the center of the squeezed portion E in the left-right direction at the center of the absorbent core 11A in the left-right direction and in the center of the absorbent body 10 in the left-right direction, the absorbent core 11A is provided with respect to the movement of the wearer. Can reduce the risk of biased deformation in the left-right direction.

全ての圧搾部Eの、左右方向の長さWeの和(ΣWe)が、上下方向の長さDeの和(ΣDe)よりも大きい(ΣWe>ΣDe)。つまり、図5に示すように、複数の圧搾部Eは、長手方向に沿って圧搾部E1、E2、E3、・・・が腹側から順に配置されている。このとき、全ての圧搾部E(E1、E2、E3、・・・)の左右方向の長さWeの和(We1+We2+We3+・・・)が、全ての圧搾部E(E1、E2、E3、・・・)の上下方向の長さ(De1+De2+De3+・・・)よりも大きいことが好ましい。これによって、全ての圧搾部Eの、左右方向の長さの和(ΣWe)が、上下方向の長さの和(ΣDe)よりも小さい場合よりも、吸収性コア11Aの左右方向の剛性を高くすることができ、吸収性コア11Aを平面形状に維持しやすくなる。 The sum of the lengths We in the left-right direction (ΣWe) of all the squeezed portions E is larger than the sum of the lengths De in the vertical direction (ΣDe) (ΣWe> ΣDe). That is, as shown in FIG. 5, in the plurality of squeezed portions E, the squeezed portions E1, E2, E3, ... Are arranged in order from the ventral side along the longitudinal direction. At this time, the sum of the lengths We (We1 + We2 + We3 + ...) in the left-right direction of all the squeezed portions E (E1, E2, E3, ...) Is the sum of all the squeezed portions E (E1, E2, E3, ...). ()) Is preferably larger than the vertical length (De1 + De2 + De3 + ...). As a result, the rigidity of the absorbent core 11A in the left-right direction is higher than that in the case where the sum of the lengths in the left-right direction (ΣWe) of all the squeezed portions E is smaller than the sum of the lengths in the up-down direction (ΣDe). This makes it easier to maintain the absorbent core 11A in a planar shape.

なお、圧搾部Eは湾曲した形状であったり、1つ以上の角を有する形状であったりするなど所望の形状でもよい。ただし、所望の形状であっても、全ての圧搾部Eの、左右方向の長さWeの和(ΣWe)が、上下方向の長さDeの和(ΣDe)よりも大きい(ΣWe>ΣDe)ことが好ましい。全ての圧搾部Eの、左右方向の長さの和(ΣWe)が、上下方向の長さの和(ΣDe)よりも小さい場合よりも、吸収性コア11Aの左右方向の剛性を高くすることができるためである。 The pressed portion E may have a desired shape such as a curved shape or a shape having one or more corners. However, even if the shape is desired, the sum of the lengths We in the left-right direction (ΣWe) of all the squeezed portions E is larger than the sum of the lengths De in the vertical direction (ΣDe) (ΣWe> ΣDe). Is preferable. It is possible to increase the rigidity of the absorbent core 11A in the left-right direction than when the sum of the lengths in the left-right direction (ΣWe) of all the squeezed portions E is smaller than the sum of the lengths in the up-down direction (ΣDe). Because it can be done.

圧搾部Eは、左右方向に沿った直線形状であることがより好ましい。剛性を高くした領域が左右方向に沿った直線となるため、吸収性コア11Aの左右方向の剛性を増しやすくなり、吸収性コア11Aを平面形状に維持しやすくなる。 It is more preferable that the squeezed portion E has a linear shape along the left-right direction. Since the region where the rigidity is increased becomes a straight line along the left-right direction, it becomes easy to increase the rigidity of the absorbent core 11A in the left-right direction, and it becomes easy to maintain the absorbent core 11A in a planar shape.

上下方向においては、圧搾部Eの寸法(De)より、隣接する圧搾部E同士の間隔の寸法Duの方が長い(De<Du)。つまり、圧搾部Eの上下方向の長さ(De)より、上下方向に隣接する圧搾部Eの間隔(Du)の方が長いため、上下方向においては、圧搾部Eの剛性が高い領域よりも、非圧搾部Uの剛性が低い領域の方が長い。そのため、圧搾部Eによって吸収性コア11Aが硬くなりすぎる恐れを軽減させることができ、着用者が感じる肌触りを向上させることができる。 In the vertical direction, the dimension Du of the distance between the adjacent pressing portions E is longer than the dimension (De) of the pressing portion E (De <Du). That is, since the distance (Du) between the squeezed portions E adjacent to each other in the vertical direction is longer than the length (De) in the vertical direction of the squeezed portion E, the interval (Du) of the squeezed portions E adjacent to the squeezed portion E is longer in the vertical direction than the region where the rigidity of the squeezed portion E is high. The region where the rigidity of the non-squeezed portion U is low is longer. Therefore, it is possible to reduce the possibility that the absorbent core 11A becomes too hard due to the squeezed portion E, and it is possible to improve the feel of the wearer.

また、幅狭部11fn、最狭部11nを有する吸収性コア11Aは、幅狭部11fn等を有さない吸収性コアよりも左右方向の剛性が低くなってしまう。そのため、幅狭部11fnに設けられている圧搾部Eの左右方向の長さ(We)を、最狭部11nの左右方向の長さ(Wn)以上とすることで(We≧Wn)、圧搾部Eの左右方向の長さが最狭部11nの左右方向の長さより短い場合よりも吸収性コア11Aの左右方向の剛性を高くすることができる。 Further, the absorbent core 11A having the narrow portion 11fn and the narrowest portion 11n has lower rigidity in the left-right direction than the absorbent core having no narrow portion 11fn or the like. Therefore, by setting the length (We) in the left-right direction of the squeezing portion E provided in the narrow portion 11fn to be equal to or greater than the length (Wn) in the left-right direction of the narrowest portion 11n (We ≧ Wn), squeezing is performed. The left-right rigidity of the absorbent core 11A can be increased as compared with the case where the left-right length of the portion E is shorter than the left-right length of the narrowest portion 11n.

また、圧搾部Eの左右方向の長さ(We)が、防漏壁部50の左右方向の内側の端同士の距離(Dg)以上であることが好ましい(We≧Dg)。図2に示すように、圧搾部Eの左右方向の長さ(We)は、防漏壁の左右方向の内側の端同士の距離(Dg)に等しい(We=Dg)。このようにすることで、圧搾部Eの左右方向の長さ(We)が、防漏壁部50の左右方向の内側の端同士の距離(Dg)より短い場合よりも、吸収性コア11Aの剛性を高めることができる。なお、圧搾部Eの左右方向の長さ(We)を長くすればするほど、吸収性コア11Aの左右方向の剛性は高くなる。 Further, it is preferable that the length (We) of the squeezed portion E in the left-right direction is equal to or greater than the distance (Dg) between the inner ends of the leak-proof wall portion 50 in the left-right direction (We ≧ Dg). As shown in FIG. 2, the length (We) in the left-right direction of the squeezed portion E is equal to the distance (Dg) between the inner ends of the leak-proof wall in the left-right direction (We = Dg). By doing so, the length (We) of the squeezed portion E in the left-right direction is shorter than the distance (Dg) between the inner ends of the leak-proof wall portion 50 in the left-right direction of the absorbent core 11A. Rigidity can be increased. The longer the length (We) of the squeezed portion E in the left-right direction, the higher the rigidity of the absorbent core 11A in the left-right direction.

さらに、図2及び図5に示すように、後側コア部11Abにも少なくとも1つの圧搾部Eが設けられている。前側コア部11Afに設けられている圧搾部Eのうちの1つを前側圧搾部(ある圧搾部)Ep、後側コア部11Abに設けられている圧搾部のうちの1つを後側圧搾部(他の圧搾部)Eqとする。具体的には、前側コア部11Afのうち中央部C10から上側に向かって4つ目の圧搾部Eを前側圧搾部Epとし、後側コア部11Abのうち中央部C10から上側に向かって4つ目の圧搾部Eを後側圧搾部Eqとする。おむつ1の伸長状態において、前側圧搾部Epと後側圧搾部Eqの左右方向の長さは同じWeである。このとき、前側圧搾部Epの左右方向の端は、前側コア部11Afの端に接しており、後側圧搾部Eqの左右方向の端は、後側コア部11Abの端に達していないことが好ましい。つまり、左右方向において、前側圧搾部Epの端より外側には非圧搾部Uが設けられていないが、後側圧搾部Eqの端より外側には非圧搾部Uが設けられている。 Further, as shown in FIGS. 2 and 5, at least one pressing portion E is also provided on the rear core portion 11Ab. One of the squeezing portions E provided on the front core portion 11Af is the front squeezing portion (a certain squeezing portion) Ep, and one of the squeezing portions provided on the rear core portion 11Ab is the posterior squeezing portion. (Other squeezed part) Eq. Specifically, the fourth squeezed portion E from the central portion C10 of the front core portion 11Af to the upper side is referred to as the front squeezed portion Ep, and four of the posterior core portions 11Ab from the central portion C10 to the upper side. The squeezed portion E of the eye is referred to as the posterior squeezed portion Eq. In the extended state of the diaper 1, the lengths of the anterior pressing portion Ep and the posterior pressing portion Eq in the left-right direction are the same We. At this time, the left-right end of the front compression portion Ep is in contact with the end of the front core portion 11Af, and the left-right end of the rear compression portion Eq does not reach the end of the rear core portion 11Ab. preferable. That is, in the left-right direction, the non-squeezed portion U is not provided outside the end of the front squeezed portion Ep, but the non-squeezed portion U is provided outside the end of the posterior squeezed portion Eq.

このように、前側コア部11Afは、前側幅狭部11fnを有することで、乳幼児の脚を動かしやすくしている一方で、前側コア部11Afの左右方向の端まで圧搾部Epを設けて前側コア部11Afの剛性を高めている。つまり、前側コア部11Afは、乳幼児の脚の可動性を高めつつ、前側コア部11Afを平面形状に保ちやすくして、吸収性本体10をすっきりとした印象になりやすくしている。一方、後側コア部11Abは、圧搾部Eqの左右方向の外側に、非圧搾部Uを有するため、左右方向において、剛性が高い圧搾部Eqについては、後側コア部11Abを平面形状に保ちつつ、圧搾部Eqより外側の剛性が低い非圧搾部Uは、臀部の形状に沿いやすくなる。この臀部に沿った形状の非圧搾部Uによって***物が左右方向の外側に漏れるのを堰き止めやすくなる。 As described above, the front core portion 11Af has the front narrow portion 11fn to facilitate the movement of the infant's legs, while the front core portion 11Af is provided with the squeezing portion Ep up to the left-right end of the front core portion 11Af. The rigidity of the portion 11Af is increased. That is, the front core portion 11Af enhances the mobility of the legs of the infant and makes it easy to keep the front core portion 11Af in a planar shape, so that the absorbent body 10 tends to have a neat impression. On the other hand, since the rear core portion 11Ab has a non-squeezed portion U on the outside in the left-right direction of the squeezed portion Eq, the rear core portion 11Ab is kept in a planar shape for the squeezed portion Eq having high rigidity in the left-right direction. On the other hand, the non-squeezed portion U having a lower rigidity outside the compressed portion Eq tends to follow the shape of the buttocks. The non-squeezed portion U shaped along the buttocks makes it easier to prevent excrement from leaking to the outside in the left-right direction.

さらに、後側コア部11Abに設けられた圧搾部Eの左右方向の長さ(Web)が、最狭部11nの左右方向の長さ(Wn)以上であることがより好ましい(Web≧Wn)。後側コア部11Abに圧搾部Eを設けることで、後側コア部11Abの左右方向の剛性を向上させることができる。しかし、仮に後側コア部11Abの圧搾部Eの左右方向の長さ(Web)を最狭部11nの左右方向の長さ(Wn)よりも短くすると、後側コア部11Abが、吸収性コア11Aが乳幼児のお尻の窪みに入り込む形状に変形をしてしまう恐れがある。そのため、後側コア部11Abの圧搾部Eの左右方向の長さ(We)を最狭部11nの左右方向の長さ(Wn)以上とすることで、後側コア部11Abの圧搾部Eの左右方向の長さ(Web)を最狭部11nの左右方向の長さ(Wn)よりも短くした場合よりも後側コア部11Abの圧搾部Eを平面形状に保ちやすくすることができる。 Further, it is more preferable that the left-right length (Web) of the squeezed portion E provided in the rear core portion 11Ab is equal to or more than the left-right length (Wn) of the narrowest portion 11n (Web ≧ Wn). .. By providing the squeezing portion E on the rear core portion 11Ab, the rigidity of the rear core portion 11Ab in the left-right direction can be improved. However, if the left-right length (Web) of the squeezed portion E of the rear core portion 11Ab is shorter than the left-right length (Wn) of the narrowest portion 11n, the rear core portion 11Ab becomes an absorbent core. There is a risk that 11A will be deformed into a shape that fits into the dent of the infant's buttocks. Therefore, by setting the length (We) of the squeezed portion E of the rear core portion 11Ab in the left-right direction to be equal to or greater than the length (Wn) of the narrowest portion 11n in the left-right direction, the squeezed portion E of the rear core portion 11Ab It is possible to make it easier to keep the squeezed portion E of the rear core portion 11Ab in a planar shape as compared with the case where the length in the left-right direction (Web) is shorter than the length in the left-right direction (Wn) of the narrowest portion 11n.

同様に、前側コア部11Afの最狭部11nより上側の領域において、圧搾部Eの左右方向の端が、前側コア部11Afの左右方向の端に接していないことがより好ましい。つまり、図5において、圧搾部E1、E2、E3の左右方向の各端と、前側コア部11Afの左右方向の端との間に非圧搾部Uを有している。前側コア部11Afのうち、最狭部11nより上側は、腹部に近い領域であるため、圧搾部Eを広く形成すると、着用者は吸収性コア11Aの硬さを感じてしまう恐れがある。そのため、着用者の腹部やそけい部の動きを制限しないようにし、吸収性コア11Aが過度に硬くなるのを防ぐことができる。 Similarly, in the region above the narrowest portion 11n of the front core portion 11Af, it is more preferable that the left-right end of the squeezing portion E does not touch the left-right end of the front core portion 11Af. That is, in FIG. 5, a non-squeezed portion U is provided between the left-right ends of the squeezed portions E1, E2, and E3 and the left-right ends of the front core portion 11Af. Since the upper part of the front core portion 11Af above the narrowest portion 11n is a region close to the abdomen, if the squeezed portion E is formed widely, the wearer may feel the hardness of the absorbent core 11A. Therefore, the movement of the wearer's abdomen and groin can be prevented from being restricted, and the absorbent core 11A can be prevented from becoming excessively stiff.

図2等に示すように、圧搾部Eは、前側コア部11Afのうち、腹側胴回り部20の下端よりも上側にも設けられていることが好ましい。つまり、腹側胴回り部20と前後方向で重なる部分に圧搾部Eを備えることが好ましい。これにより、剛性の高くなった吸収性コア11を腹側胴回り部20の腹側胴回り伸縮部材23で着用者の肌に押し当て密着させることができるため、吸収性本体10を着用者の肌にフィットさせやすくなる。 As shown in FIG. 2 and the like, it is preferable that the squeezing portion E is also provided above the lower end of the ventral waist circumference portion 20 in the front core portion 11Af. That is, it is preferable to provide the squeezed portion E in the portion that overlaps the ventral waist circumference portion 20 in the front-rear direction. As a result, the highly rigid absorbent core 11 can be pressed against the wearer's skin by the ventral waistline elastic member 23 of the ventral waistline portion 20 to be brought into close contact with the wearer's skin, so that the absorbent body 10 can be brought into close contact with the wearer's skin. It will be easier to fit.

図8に示すように、前側コア部11Afの圧搾部Eの左右方向の両端が、非伸縮領域Ffよりもそれぞれ外側に設けられていることが好ましい。非伸縮領域Ffは腹側胴回り伸縮部材23の収縮力が働かない領域であるため、吸収性本体10が着用者の肌から離れて浮きやすい領域である。そのため、非伸縮領域Ffよりも左右方向に長い領域に亘って吸収性コア11Aの剛性を高めることで、吸収性本体10が肌に接する状態を保ちやすくなる。なお、圧搾部Eの左右方向の両端がそれぞれ伸縮領域Df内に設けられていることがより好ましい。伸縮領域Dfが圧搾部Eの各両端を肌に接する方向への力を加えるため、非伸縮領域Ffと前後方向で重なる吸収性本体10の部分についても着用者の肌に接してフィットした状態に維持しやすくなる。 As shown in FIG. 8, it is preferable that both ends of the squeezed portion E of the front core portion 11Af in the left-right direction are provided outside the non-stretchable region Ff. Since the non-stretchable region Ff is a region where the contraction force of the ventral waist circumference elastic member 23 does not work, the absorbent main body 10 is a region where the absorbent body 10 easily floats away from the wearer's skin. Therefore, by increasing the rigidity of the absorbent core 11A over a region longer in the left-right direction than the non-stretchable region Ff, it becomes easier to maintain the state in which the absorbent main body 10 is in contact with the skin. It is more preferable that both ends of the squeezed portion E in the left-right direction are provided in the expansion / contraction region Df. Since the stretchable region Df applies a force in the direction in which both ends of the squeezed portion E are in contact with the skin, the portion of the absorbent body 10 that overlaps the non-stretchable region Ff in the front-rear direction is also in a state of being in contact with the wearer's skin. It will be easier to maintain.

===その他の実施の形態===
以上、本発明の実施形態について説明したが、上記の実施形態は、本発明の理解を容易にするためのものであり、本発明を限定して解釈するためのものではない。また、本発明は、その趣旨を逸脱することなく、変更や改良され得るとともに、本発明にはその等価物が含まれるのはいうまでもない。例えば、以下に示すような変形が可能である。
=== Other embodiments ===
Although the embodiments of the present invention have been described above, the above-described embodiments are for facilitating the understanding of the present invention, and are not intended to limit the interpretation of the present invention. Further, the present invention can be changed or improved without departing from the spirit thereof, and it goes without saying that the present invention includes an equivalent thereof. For example, the following modifications are possible.

上述の実施形態においては、左右方向に沿った直線状の圧搾部Eを設けたが、圧搾部の形状はこれに限られない。左右方向に所定の長さを有する圧搾部Eであれば、波型等の所望の形状とすることができる。図9Aは、別の実施形態にかかる吸収体11を説明する図である。図9Aにおいては、吸収性コア11A等は、コアラップシート11Bに覆われているが、便宜上実線で示している。図9Aに示すように、腹側に凸形状を有する山型の圧搾部Eであってもよい。圧搾部Eは、左右方向の一方側から他方側まで連続した連続圧搾形状を有している。圧搾部Eの上端のうち、左右方向において、最も下側に位置する部位Ejから最も上側に位置する部位Ekをつなぐ直線と、左右方向に沿った直線とがなす角度のうち、小さい方の角度θeが45度よりも小さいことが好ましい(θe<45°)。これによって、θeが45度以上であった場合よりも、圧搾部Eによって吸収性コア11Aの剛性を高くすることができるため、吸収性コア11Aを平面形状に維持しやすくなる。 In the above-described embodiment, the linear pressing portion E along the left-right direction is provided, but the shape of the pressing portion is not limited to this. If the squeezed portion E has a predetermined length in the left-right direction, it can have a desired shape such as a corrugated shape. FIG. 9A is a diagram illustrating an absorber 11 according to another embodiment. In FIG. 9A, the absorbent core 11A and the like are covered with the core wrap sheet 11B, but are shown by solid lines for convenience. As shown in FIG. 9A, it may be a mountain-shaped squeezed portion E having a convex shape on the ventral side. The squeezed portion E has a continuous squeezing shape from one side in the left-right direction to the other side. Of the upper ends of the squeezed portion E, the smaller angle between the straight line connecting the lowermost part Ej and the uppermost part Ek in the left-right direction and the straight line along the left-right direction. It is preferable that θe is smaller than 45 degrees (θe <45 °). As a result, the rigidity of the absorbent core 11A can be increased by the pressing portion E as compared with the case where θe is 45 degrees or more, so that the absorbent core 11A can be easily maintained in a planar shape.

この場合においても、全ての圧搾部Eの、左右方向の長さWeの和(ΣWe)が、上下方向の長さDeの和(ΣDe)よりも大きい(ΣWe>ΣDe)。つまり、図9Aに示すように、複数の圧搾部Eは、長手方向に沿って圧搾部E21、E22、E23、・・・が腹側から順に配置されている。このとき、全ての圧搾部E(E21、E22、E23、・・・)の左右方向の長さWeの和(We21+We22+We23+・・・)が、全ての圧搾部E(E21、E22、E23、・・・)の上下方向の長さ(De21+De22+De23+・・・)よりも大きいことが好ましい。これによって、全ての圧搾部Eの、左右方向の長さの和(ΣWe)が、上下方向の長さの和(ΣDe)よりも小さい場合よりも、吸収性コア11Aの左右方向の剛性を高くすることができる。 Also in this case, the sum of the lengths We in the left-right direction (ΣWe) of all the squeezed portions E is larger than the sum of the lengths De in the vertical direction (ΣDe) (ΣWe> ΣDe). That is, as shown in FIG. 9A, in the plurality of squeezed portions E, the squeezed portions E21, E22, E23, ... Are arranged in order from the ventral side along the longitudinal direction. At this time, the sum of the lengths We (We21 + We22 + We23 + ...) in the left-right direction of all the squeezed portions E (E21, E22, E23, ...) Is the sum of all the squeezed portions E (E21, E22, E23, ...). ()) Is preferably larger than the vertical length (De21 + De22 + De23 + ...). As a result, the rigidity of the absorbent core 11A in the left-right direction is higher than that in the case where the sum of the lengths in the left-right direction (ΣWe) of all the squeezed portions E is smaller than the sum of the lengths in the up-down direction (ΣDe). can do.

また、上述の実施形態においては、圧搾加工を施した部分を、圧搾部Eの左右方向の長さ(We)及び最狭部11nの左右方向の長さ(Wn)と同じとしたが、図9Bに示すように、圧搾加工を施した部分を、圧搾部Eの左右方向の長さ(We)及び最狭部11nの左右方向の長さ(Wn)よりも長く設けてもよい。図9Bは、別の実施形態にかかる吸収体11を説明する図である。図9Bでは、吸収性コア11A等は、コアラップシート11Bに覆われているが、便宜上実線で示している。図9Bは、吸収性コア11Aをコアラップシート11Bで覆った状態で圧搾加工をして形成した吸収体11を示している。吸収性コア11Aよりも左右方向の外側に圧搾加工が施された領域は、コアラップシート11b同士が圧搾加工された部分である。このように、吸収性コア11A内だけでなく、吸収性コア11Aが設けられていない領域に圧搾加工を施して、コアラップシート11b同士を圧搾加工してもよい。図9Bに示す例においては、吸収性コア11Aの最狭部11nの端までしっかりと圧搾加工をすることができるため、吸収性コア11Aの左右方向の剛性を確実に高めることができる。 Further, in the above-described embodiment, the portion subjected to the squeezing process is the same as the left-right length (We) of the squeezed portion E and the left-right length (Wn) of the narrowest portion 11n. As shown in 9B, the squeezed portion may be provided longer than the left-right length (We) of the squeezed portion E and the left-right length (Wn) of the narrowest portion 11n. FIG. 9B is a diagram illustrating an absorber 11 according to another embodiment. In FIG. 9B, the absorbent core 11A and the like are covered with the core wrap sheet 11B, but are shown by solid lines for convenience. FIG. 9B shows an absorber 11 formed by pressing the absorbent core 11A in a state of being covered with the core wrap sheet 11B. The region that has been squeezed to the outside in the left-right direction of the absorbent core 11A is a portion where the core wrap sheets 11b have been squeezed together. As described above, not only the inside of the absorbent core 11A but also the region where the absorbent core 11A is not provided may be pressed to press the core wrap sheets 11b to each other. In the example shown in FIG. 9B, since the absorbent core 11A can be firmly pressed to the end of the narrowest portion 11n, the rigidity of the absorbent core 11A in the left-right direction can be surely increased.

さらに、上述の実施形態においては、圧搾部Eを上下方向において等間隔に配置したが、これに限られない。圧搾部Eを不等間隔に配置してもよい。例えば、図10は、別の実施形態にかかる展開状態且つ伸長状態のおむつ1を肌側から見た概略平面図である。図10に示すように、前側コア部11Afの圧搾部Eのうち、最も下側に位置する下側圧搾部Eaと、下側圧搾部Eaに上側から隣接する隣接下側圧搾部Ebとの間隔Dabを、腹側胴回り部20の下端よりも下側に設けられた圧搾部Eのうち最も上側に位置する上側圧搾部Ecと、上側圧搾部Ecに下側から隣接する隣接上側圧搾部Edとの間隔Dcdよりも小さくてもよい(Dab<Dcd)。このようにすることで、前側コア部11Afのうち、着用者の脚によって吸収性コア11Aが変形する恐れが低い前側コア部11Afの上側の領域は、圧搾部Eをより少なく設けて、吸収性コア11Aが過度に硬くなってしまう恐れを防ぐことができる。一方、吸収性コア11Aが変形する恐れが高い前側コア部11Afの下側の領域には、より多くの圧搾部Eを設けることで、吸収性コア11Aの左右方向の剛性を高めて、吸収性コア11Aを平面形状に維持しやすくすることができる。 Further, in the above-described embodiment, the squeezed portions E are arranged at equal intervals in the vertical direction, but the present invention is not limited to this. The squeezed portions E may be arranged at unequal intervals. For example, FIG. 10 is a schematic plan view of the unfolded and stretched diaper 1 according to another embodiment as viewed from the skin side. As shown in FIG. 10, among the squeezed portions E of the front core portion 11Af, the distance between the lower squeezed portion Ea located at the lowermost side and the adjacent lower squeezed portion Eb adjacent to the lower squeezed portion Ea from above. The Dab is the upper squeezing portion Ec located on the uppermost side of the squeezing portion E provided below the lower end of the ventral waist circumference portion 20, and the adjacent upper squeezing portion Ed adjacent to the upper squeezing portion Ec from the lower side. The interval Dcd may be smaller than the interval Dcd (Dab <Dcd). By doing so, of the front core portion 11Af, the upper region of the front core portion 11Af where the possibility that the absorbent core 11A is less likely to be deformed by the wearer's leg is provided with less pressing portion E and is absorbent. It is possible to prevent the core 11A from becoming excessively hard. On the other hand, by providing a larger number of squeezed portions E in the lower region of the front core portion 11Af where the absorbent core 11A is likely to be deformed, the rigidity of the absorbent core 11A in the left-right direction is increased and the absorbent core 11A is absorbed. The core 11A can be easily maintained in a planar shape.

上述の実施形態においては、吸収性コア11Aに、全て同じ溝の深さの圧搾部Eを複数形成したが、これに限られない。吸収性コア11A内において、異なる深さの圧搾部Eを形成してもよい。例えば、前側コア部11Afのうち、より左右方向の剛性を高くしたい前側コア部Aの最狭部11nには、より深い溝の圧搾部Eを形成し、腹側胴回り部20に近い部分には、より浅い溝の圧搾部Eを形成してもよい。 In the above-described embodiment, a plurality of squeezed portions E having the same groove depth are formed in the absorbent core 11A, but the present invention is not limited to this. Squeezed portions E of different depths may be formed within the absorbent core 11A. For example, of the front core portion 11Af, a deeper groove pressing portion E is formed in the narrowest portion 11n of the front core portion A for which it is desired to increase the rigidity in the left-right direction, and a portion close to the ventral waist circumference portion 20 is formed. , The squeezed portion E of the shallower groove may be formed.

また、吸収性コア11Aに施す圧搾部Eの左右方向の長さ及び上下方向の長さは、必ずしも全て同じでなくてもよい。おむつ1の圧搾部Eは、全ての圧搾部Eの左右方向の長さ及び上下方向の長さを同じとしたが、それぞれ異なる長さとすることもできる。例えば、より左右方向の剛性を高くしたい前側コア部Aの下側の領域には、左右方向の長さ及び上下方向の長さがそれぞれ長い圧搾部Eを形成し、吸収性本体10の変形がより少ない腹側胴回り部20に近い部分には、左右方向の長さ及び上下方向の長さがそれぞれ短い圧搾部Eを形成してもよい。 Further, the length in the left-right direction and the length in the up-down direction of the squeezed portion E applied to the absorbent core 11A do not necessarily have to be the same. The squeezed portion E of the diaper 1 has the same length in the left-right direction and the length in the vertical direction of all the squeezed portions E, but they may have different lengths. For example, in the lower region of the front core portion A for which it is desired to increase the rigidity in the left-right direction, a squeezed portion E having a long left-right length and a long vertical length is formed, and the absorbent body 10 is deformed. A squeezed portion E having a short left-right length and a short vertical length may be formed in a portion closer to the ventral waist circumference portion 20 which is smaller.

上述の実施形態においては、腹側胴回り部20、背側胴回り部30、防漏壁部50、及び脚回り部60が備える伸縮部材(22、32、51、16)として糸ゴム及び伸縮シートを例示しているがこれに限らない。例えば、糸ゴムや伸縮シートだけでなく、伸縮性フィルム等のシート状の伸縮部材を単数又は複数配してもよい。また、図面には伸縮部材のうち伸縮性を発現する部位(所謂有効長の部位)のみを示している。そのため図示する伸縮部材の長手方向の外側に伸縮性を発現しない伸縮部材の部位が存在していてもよい。また、伸縮部材の配置や本数も図示する構成に限らない。 In the above-described embodiment, the rubber thread and the elastic sheet are used as the elastic members (22, 32, 51, 16) provided in the ventral waist circumference portion 20, the dorsal waist circumference portion 30, the leak-proof wall portion 50, and the leg circumference portion 60. Although it is illustrated, it is not limited to this. For example, not only a rubber thread or an elastic sheet but also a single or a plurality of sheet-shaped elastic members such as an elastic film may be arranged. Further, the drawing shows only the part of the stretchable member that exhibits elasticity (so-called effective length part). Therefore, there may be a portion of the stretchable member that does not exhibit stretchability on the outside in the longitudinal direction of the stretchable member shown in the figure. Further, the arrangement and the number of the telescopic members are not limited to the configuration shown in the figure.

上述の実施形態においては、パンツ型吸収性物品は、腹側胴回り部20と背側胴回り部30と吸収性本体10とを有する所謂3ピースタイプの使い捨ておむつとして説明したがこれに限られない。例えば、外装シート14が腹側胴回り部20と後胴回り30とを繋いで一体化されたおむつ(所謂2ピースタイプ)であってもよい。 In the above-described embodiment, the pants-type absorbent article has been described as a so-called three-piece type disposable diaper having a ventral waist circumference portion 20, a dorsal waist circumference portion 30, and an absorbent main body 10, but the present invention is not limited thereto. For example, the exterior sheet 14 may be a diaper (so-called two-piece type) in which the ventral waist circumference 20 and the rear waist circumference 30 are connected and integrated.
