Description

本発明は、着用者の股部を含む領域に装着される吸収性物品、その吸収性物品に付与される表面ライナーに関する。 The present invention relates to an absorbent article to be worn in a region including a wearer's crotch, and a surface liner applied to the absorbent article.

この種の吸収性物品では、着用者の排泄物が前後左右に広がってしまう場合がある。広がった排泄物は、吸収性物品の前後左右の縁部から外部に漏れる場合があるとともに、着用者の肌面の広範囲に付着してしまう。排泄物が肌面の広範囲に付着すると、吸収性物品の交換時の拭き取りに手間がかかり、吸収性物品の交換作業の負担が増える。特に、軟便（液状の便、又は液状の成分と固形成分と混じり合った便）の場合は、着用者の肌面と吸収性物品との間で広がりやすいとともに、肌面の広範囲に付着すると拭き取りの負担が大きい。 In this type of absorbent article, the excrement of the wearer may spread from front to back and from side to side. The spread excrement may leak to the outside from the front, rear, left and right edges of the absorbent article, and adhere to a wide range of the wearer's skin. When excrement adheres to a wide area of the skin surface, it takes time and effort to wipe the absorbent article, and the load of the absorbent article is increased. In particular, in the case of soft stool (liquid stool or stool mixed with liquid and solid components), it is easy to spread between the skin surface of the wearer and the absorbent article and wipes off if it adheres to a wide area of the skin surface. The burden of is great.

また、吸収性物品は左右方向（横方向）の幅よりも前後方向（縦方向）の幅の方が大きいため、軟便等の排泄物が前後方向に広がった場合には、非常に広範囲において排泄物の拭き取りが必要となる。このため、軟便等の排泄物の前後方向の広がりを抑制できれば、拭き取り作業の負担軽減の効果が大きい。ここで、軟便等の排泄物が前後方向（縦方向）に広がりやすい理由としては、次の点が挙げられる。一つは、着用者の臀部に吸収性物品をあてたときに、吸収性物品に縦方向に沿って延びる凹凸部が形成されやすく、その凹凸部に沿って排泄物が移動しやすい点が挙げられる。もう一つは、排泄物の左右方向（横方向）への広がりは立体ギャザー等で抑制できるが、排泄物の前後方向への広がりを抑制するための有効な手段がなかなか存在しなかった点が挙げられる。 In addition, since the absorbent article is wider in the front-rear direction (vertical direction) than in the left-right direction (lateral direction), if excrement such as loose stool spreads in the front-rear direction, it is excreted in a very wide range. Things need to be wiped off. For this reason, if the spread of excrement such as loose stool can be suppressed in the front-rear direction, the effect of reducing the burden of wiping work is great. Here, the following points are mentioned as the reason why excrement such as loose stool is likely to spread in the front-rear direction (vertical direction). One is that when the absorbent article is applied to the wearer's buttocks, the absorbent article is easily formed with an uneven part extending along the longitudinal direction, and excrement easily moves along the uneven part. It is done. The other is that the spread of excrement in the left-right direction (lateral direction) can be suppressed by three-dimensional gathering, etc., but there were few effective means for suppressing the excrement spread in the front-rear direction. Can be mentioned.

一方、従来の吸収性物品として、複数の開口が設けられたトップシートを有するものが提案されている（特許文献１）。この特許文献１では、吸収性物品が着用者に装着されたときに付与される張力によって、トップシートの開口が開くようになっている。そして、着用者の排泄物が前記開口を介してトップシートの外面側に通過し、トップシートの外面側で捕捉されるようになっている。
特表２００２−５２８１７４号公報 On the other hand, as a conventional absorbent article, one having a top sheet provided with a plurality of openings has been proposed (Patent Document 1). In Patent Document 1, the opening of the top sheet is opened by the tension applied when the absorbent article is attached to the wearer. And a wearer's excrement passes through the said opening to the outer surface side of a top sheet, and is caught by the outer surface side of a top sheet.
JP-T-2002-528174

しかしながら、上述の特許文献１では、トップシートには複数の開口部が形成されるのみであるため、排泄物が広がるのを積極的に抑制するための構成がない。このため、排泄物が広がるのを止められない。 However, in the above-mentioned Patent Document 1, since only a plurality of openings are formed in the top sheet, there is no configuration for positively suppressing the spread of excrement. For this reason, it cannot stop that excrement spreads.

そこで、本発明の解決すべき課題は、排泄物が広がるのを抑制するとともに、排泄物を確実に捕捉することができる吸収性物品及び表面ライナーを提供することである。 Therefore, the problem to be solved by the present invention is to provide an absorbent article and a surface liner that can prevent the excrement from spreading and can reliably capture the excrement.

請求項１、請求項５及び請求項６に記載の発明によれば、吸収性物品の肌面側に設けられた表面シートに形成された３次元的な凹凸構造によって排泄物が広がるのを効果的に堰き止めつつ、３次元構造の凹部及び表面シートに形成された複数の開口部によって排泄物を効果的に捕捉できる。その結果、軟便等の排泄物が着用者の肌面の広範囲に付着するのを防止でき、排泄物の拭き取り作業の負担を軽減できる。 According to invention of Claim 1 , Claim 5 and Claim 6, it is effective that excrement spreads by the three-dimensional uneven structure formed in the surface sheet provided in the skin surface side of the absorbent article. The excrement can be effectively captured by the plurality of openings formed in the concave portion and the surface sheet of the three-dimensional structure while damming up. As a result, excrement such as loose stool can be prevented from adhering to a wide range of the skin surface of the wearer, and the burden of wiping off excrement can be reduced.

また、排泄物を表面シートの３次元的な凹凸構造によって堰き止めることにより、排泄物の液体成分を吸収コアにより素早くかつ確実に捕捉できる。これによって、排泄物の漏れについてもより確実に防止できる。 Moreover, the liquid component of excrement can be quickly and reliably captured by the absorption core by blocking excrement by the three-dimensional uneven structure of the top sheet. Thereby, it is possible to more reliably prevent the leakage of excrement.

また、複数の弾性部材及び複数の切り込み列が設けられた表面シートを弾性部材の収縮力により収縮させるだけで、表面シートに複数の開口部及び３次元的な凹凸構造が形成されるため、３次元的な凹凸構造を形成するために表面シートに複雑な加工を施す必要がない。 In addition, since the top sheet provided with a plurality of elastic members and a plurality of cut rows is contracted by the contracting force of the elastic member, a plurality of openings and a three-dimensional uneven structure are formed on the top sheet. There is no need to perform complicated processing on the surface sheet in order to form a three-dimensional uneven structure.

また、複数の弾性部材及び複数の切り込み列の構成等を変更することにより、開口部及び３次元的な凹凸構造の形態を容易に変更できる。 Moreover, the form of an opening part and a three-dimensional uneven | corrugated structure can be easily changed by changing the structure etc. of a some elastic member and several notch row | line | column.

請求項７に記載の発明によれば、弾性部材の収縮力により表面シートが部分的に縦方向に収縮されるのに伴って各切り込み部の２つのスリットの間の部分が略弓状に変形することによって、複数の開口部及び３次元的な凹凸構造が形成される。それ故、簡単な構成により、複数の開口部及び３次元的な凹凸構造を表面シートに形成できる。 According to the seventh aspect of the present invention, as the surface sheet is partially contracted in the vertical direction by the contraction force of the elastic member, the portion between the two slits of each cut portion is deformed into a substantially arcuate shape. By doing so, a plurality of openings and a three-dimensional uneven structure are formed. Therefore, with a simple configuration, a plurality of openings and a three-dimensional uneven structure can be formed on the surface sheet.

また、表面シートに形成された各切り込み部の２つのスリットの間の部分が、縦方向を向くようにして隆起するため、この隆起部によって、軟便に含まれる流動性の高い液体成分の縦方向への流れを効果的に阻止できる。 In addition, since the portion between the two slits of each cut portion formed in the top sheet is raised so as to face the vertical direction, the vertical direction of the liquid component having high fluidity contained in the soft stool is raised by this raised portion. Can be effectively prevented.

請求項１及び請求項８に記載の発明によれば、弾性部材の収縮力により表面シートが部分的に縦方向に収縮されるのに伴って各切り込み部の内側部分が肌面側又は外面側に変位されることによって、複数の開口部及び３次元的な凹凸構造が形成される。それ故、簡単な構成により、複数の開口部及び３次元的な凹凸構造を表面シートに形成できる。 According to the first and eighth aspects of the present invention, as the topsheet is partially contracted in the vertical direction by the contraction force of the elastic member, the inner portion of each cut portion is the skin surface side or the outer surface side. As a result of the displacement, a plurality of openings and a three-dimensional uneven structure are formed. Therefore, with a simple configuration, a plurality of openings and a three-dimensional uneven structure can be formed on the surface sheet.

また、表面シートに形成された各切り込み部の内側部分が縦方向を向くようにして立ち上がるため、その立ち上がった部分によって、軟便に含まれる流動性の高い液体成分の縦方向（前後方向）への流れを効果的に阻止できる。 In addition, since the inner part of each cut portion formed in the top sheet rises in the vertical direction, the raised part causes the liquid component with high fluidity contained in the stool to move in the vertical direction (front-rear direction). The flow can be effectively blocked.

請求項９に記載の発明によれば、表面シートにおける各切り込み部の内側部分の自由端側の部分が、吸収性物品における表面シートの外面側に位置する部材に接合されているため、弾性部材の収縮に伴って外面側に変位した切り込み部の内側部分の起立姿勢を確実に保持できる。このため、表面シートの外面側の部材と接合された切り込み部の内側部分によって、表面シートの外面側に誘導された軟便等の排泄物をより確実に堰き止めることができる。 According to the invention described in claim 9 , since the free end side portion of the inner portion of each cut portion in the topsheet is joined to the member located on the outer surface side of the topsheet in the absorbent article, the elastic member It is possible to reliably hold the standing posture of the inner portion of the cut portion displaced to the outer surface side with the contraction. For this reason, excrement such as loose stool guided to the outer surface side of the surface sheet can be more reliably dammed by the inner portion of the cut portion joined to the outer surface side member of the surface sheet.

また、弾性部材の収縮力により表面シートが部分的に縦方向に収縮されて、表面シートの複数の弾性部材が設けられた部分が表面シートの外面側に位置する部材から肌面側に浮き上がった際に、各切り込み部の内側部分が外面側の部材と接合されているため、表面シートとその外面側の部材との間に適度な隙間が形成される。これによって、開口部を介して表面シートの外面側に誘導された軟便等の収容能力を向上できる。 Further, the surface sheet is partially contracted in the vertical direction due to the contraction force of the elastic member, and the portion provided with the plurality of elastic members of the surface sheet is lifted from the member located on the outer surface side of the surface sheet to the skin surface side. At this time, since the inner portion of each cut portion is joined to the member on the outer surface side, an appropriate gap is formed between the top sheet and the member on the outer surface side. Thereby, the accommodation capacity of soft stool or the like guided to the outer surface side of the topsheet through the opening can be improved.

請求項１０に記載の発明によれば、表面シートが透液性の不織布で構成されているため、排泄物中の液体成分を素早く表面シートの外面側に透過させることができる。これによって、排泄物の拡散を抑制し、排泄物が着用者の肌面に付着する面積を抑制できる。 According to invention of Claim 10 , since the surface sheet is comprised with the liquid-permeable nonwoven fabric, the liquid component in excrement can be rapidly permeate | transmitted to the outer surface side of a surface sheet. Thereby, diffusion of excrement can be suppressed and the area where excrement adheres to the wearer's skin surface can be suppressed.

請求項１１に記載の発明によれば、表面シートが撥水性の不織布で構成されているため、一旦表面シートの外面側に誘導された排泄物の液体成分が表面シートを透過して肌面側に逆戻りするのを抑制できる。これによって、逆戻りした排泄物の液体成分が着用者の肌に付着して不快感を与えるのを防止できる。 According to the eleventh aspect of the present invention, since the top sheet is made of a water-repellent nonwoven fabric, the excrement liquid component once induced on the outer surface side of the top sheet permeates the top sheet and the skin surface side. Can be prevented from going back to Thereby, it can prevent that the liquid component of the excrement which turned backward adheres to a wearer's skin, and gives discomfort.

請求項２及び請求項５に記載の発明によれば、表面シートがトップシートの肌面側に付与されているため、表面シートの３次元的な凹凸構造及び複数の開口部によって排泄物の拡散を的確に阻止できる。 According to invention of Claim 2 and Claim 5 , since the surface sheet is provided on the skin surface side of the top sheet, diffusion of excrement is caused by the three-dimensional uneven structure and the plurality of openings of the surface sheet. Can be accurately prevented.

請求項３及び請求項６に記載の発明によれば、表面シートがトップシートと吸収コアとの間に配置されているため、表面シートの剥離又は脱落が生じるのを防止できる。 According to invention of Claim 3 and Claim 6 , since the surface sheet is arrange | positioned between the top sheet and the absorption core, it can prevent that peeling or dropping of a surface sheet arises.

なお、以下では、着用者の股部を覆うように吸収性物品１が装着されたときに、着用者の股部の前後方向に対応する吸収性物品１の方向（図１の縦方向）を「前後方向Ｙ」（縦方向）といい、着用者によって左右方向に対応する吸収性物品１の方向（図１の横方向）を「左右方向Ｘ」（横方向）という。また、着用者の股部の前方側（腹側）に対応する吸収性物品１の側を「前方側」といい、着用者の股部の後方側（後側）に対応する吸収性物品１の側を「後方側」という。図１においては、図中の上側が吸収性物品１の前方側となる。 In the following, when the absorbent article 1 is mounted so as to cover the wearer's crotch, the direction of the absorbent article 1 corresponding to the front-rear direction of the wearer's crotch (the vertical direction in FIG. 1) It is referred to as “front-rear direction Y” (longitudinal direction), and the direction of the absorbent article 1 corresponding to the left-right direction by the wearer (lateral direction in FIG. 1) is referred to as “left-right direction X” (lateral direction). Moreover, the side of the absorbent article 1 corresponding to the front side (abdomen side) of the wearer's crotch is referred to as “front side”, and the absorbent article 1 corresponding to the back side (rear side) of the wearer's crotch. This side is called the “rear side”. In FIG. 1, the upper side in the figure is the front side of the absorbent article 1.

図１及び図２に示す吸収性物品１は、使い捨ておむつとして用いられるものであり、トップシートを構成する表面シート１１に、複数の開口部１２及び３次元的な凹凸構造１３が形成されている。この開口部１２（図４及び図５参照）及び凹凸構造１３の構成については後に詳述する。 The absorbent article 1 shown in FIGS. 1 and 2 is used as a disposable diaper, and a plurality of openings 12 and a three-dimensional concavo-convex structure 13 are formed on a surface sheet 11 constituting a top sheet. . The configuration of the opening 12 (see FIGS. 4 and 5) and the concavo-convex structure 13 will be described in detail later.

吸収性物品１は、大略的に、前後方向（縦方向）Ｙに延びた吸収体１４を、トップシートである表面シート１１とバックシート１５とで挟んだ構造を有している。これにより、肌面側から表面シート１１、吸収体１４、バックシート１５の順で、これらは積層して配置される（図２参照）。このような積層構造により、排泄物の液体成分は、表面シート１１の開口部１２を通過又は表面シート１１を透過し、吸収体１４に吸収され、かつ、バックシート１５によって外部への染み出しが防止される。なお、本発明に係る内装材には表面シート１１及び後述するサイドシート１７が相当し、外装材にはバックシート１５が相当している。 The absorbent article 1 generally has a structure in which an absorbent body 14 extending in the front-rear direction (longitudinal direction) Y is sandwiched between a top sheet 11 and a back sheet 15 that are top sheets. Thereby, these are laminated | stacked and arrange | positioned in order of the surface sheet 11, the absorber 14, and the back sheet | seat 15 from the skin surface side (refer FIG. 2). With such a laminated structure, the liquid component of excrement passes through or passes through the opening 12 of the top sheet 11 and is absorbed by the absorbent body 14 and oozes out to the outside by the back sheet 15. Is prevented. The interior material according to the present invention corresponds to the top sheet 11 and a side sheet 17 described later, and the exterior material corresponds to the back sheet 15.

表面シート１１は、吸収性物品１の肌面側における左右方向Ｘの中央部に、前後方向Ｙに沿って配置される。この表面シート１１の構成については後述する。 The top sheet 11 is arranged along the front-rear direction Y at the center in the left-right direction X on the skin surface side of the absorbent article 1. The configuration of the top sheet 11 will be described later.

吸収体１４としては、例えば、粉砕したパルプ繊維やセルロース繊維等の親水性繊維集合層に粒状の高分子吸収体を混合してなる吸収コアを、ティッシュペーパー等の紙シートあるいは透液性不織布シート等の被覆シートで包み、所定の形状（長方形、砂時計型、ひょうたん型等）に成形したものが挙げられる。 Examples of the absorbent body 14 include an absorbent core formed by mixing a granular polymer absorbent body with a hydrophilic fiber aggregate layer such as pulverized pulp fiber or cellulose fiber, a paper sheet such as tissue paper, or a liquid-permeable nonwoven fabric sheet. And the like, and those formed into a predetermined shape (rectangular shape, hourglass shape, gourd shape, etc.).

バックシート１５は、吸収体１４で吸収された尿等が外側にしみ出すのを防ぐため、撥水性のシート材料又は液不透過性のシート材料を用いて形成される。例えば、通常使い捨ておむつに使用される撥水性不織布材料（スパンボンド不織布、メルトブロー不織布、ＳＭＳ不織布等）、あるいはプラスチックフィルム（通気性のものでも、非通気性のものでもよいが、より快適な態様としては通気性プラスチックフィルムが望ましい）、あるいはそれらを貼り合わせたものが用いられる。本実施形態では、バックシート１５は、通気性プラスチックフィルムと、その通気性プラスチックフィルムの外面側に貼り合わされた不織布（例えば撥水性不織布）によって構成されている。 The back sheet 15 is formed using a water-repellent sheet material or a liquid-impermeable sheet material in order to prevent urine or the like absorbed by the absorber 14 from exuding to the outside. For example, a water-repellent nonwoven fabric material (spunbond nonwoven fabric, melt blown nonwoven fabric, SMS nonwoven fabric, etc.) that is usually used for disposable diapers, or a plastic film (breathable or non-breathable, but more comfortable mode) Is preferably a breathable plastic film) or a laminate of them. In the present embodiment, the back sheet 15 is configured by a breathable plastic film and a nonwoven fabric (for example, a water-repellent nonwoven fabric) bonded to the outer surface side of the breathable plastic film.

また、吸収性物品１の肌面側における左右方向Ｘの両側には、前後方向Ｙに沿って表面シート１１に重ねて左右のサイドシート１７が設けられている。このサイドシート１７の中央側の端部には糸ゴム１８が配されており、この糸ゴム１８の収縮によってサイドシート１７の一部が肌面側に向かって立ち上がり、サイド立体ギャザーとして機能する。このサイド立体ギャザーにより排泄物の横漏れが防止される。サイドシート１７の素材としては、撥水性の不織布、又は撥水性の不織布と不透液性のプラスチックフィルムとを貼り合わせたものなどが挙げられる。 Further, left and right side sheets 17 are provided on both sides of the skin surface side of the absorbent article 1 in the left-right direction X so as to overlap the top sheet 11 along the front-rear direction Y. A thread rubber 18 is disposed at an end of the side sheet 17 on the center side, and a part of the side sheet 17 rises toward the skin surface side by the contraction of the thread rubber 18 and functions as a side three-dimensional gather. Side leakage of excrement is prevented by this side solid gather. Examples of the material for the side sheet 17 include a water-repellent nonwoven fabric or a laminate of a water-repellent nonwoven fabric and a liquid-impervious plastic film.

次に、表面シート１１の構成について説明する。表面シート１１は、図３ないし図５、図６（ａ）及び図６（ｂ）に示すように、前後方向Ｙに長い長方形の外形形状を有するシート状の部材であり、前後方向Ｙに沿って複数の弾性部材２１及び複数の切り込み列２２が設けられている。これらの弾性部材２１及び切り込み列２２は、表面シート１１における後方側に片寄った区間２３（着用者の臀部にあてがわれる領域）に形成されている。以後、この区間２３を収縮区間という。これによって、表面シート１１の複数の開口部１２及び凹凸構造１３が着用者の腹部に接触し、着用者が違和感を感じるのが防止される。 Next, the configuration of the top sheet 11 will be described. The top sheet 11 is a sheet-like member having a rectangular outer shape that is long in the front-rear direction Y, as shown in FIGS. 3 to 5, 6 (a), and 6 (b). A plurality of elastic members 21 and a plurality of cut rows 22 are provided. The elastic member 21 and the cut row 22 are formed in a section 23 (region applied to the wearer's buttocks) that is offset to the rear side of the topsheet 11. Hereinafter, this section 23 is referred to as a contraction section. This prevents the plurality of openings 12 and the concavo-convex structure 13 of the surface sheet 11 from contacting the wearer's abdomen and preventing the wearer from feeling uncomfortable.

図６（ａ）に基づいて、表面シート１１の収縮区間２３が収縮する前の状態（伸張されている状態）の収縮区間２３の構成について説明する。図６（ａ）に示すように、複数の弾性部材２１は、糸状又は帯状の形態を有し、表面シート１１の収縮区間２３内において、左右方向Ｘに間隔をあけて、かつ、前後方向Ｙに沿って伸張された状態で表面シート１１に付与されている。 Based on Fig.6 (a), the structure of the contraction area 23 of the state before the contraction area 23 of the surface sheet 11 contracts (expanded state) is demonstrated. As shown in FIG. 6A, the plurality of elastic members 21 have a thread-like or belt-like form, are spaced in the left-right direction X within the contraction section 23 of the topsheet 11, and the front-rear direction Y Is applied to the top sheet 11 in a state of being stretched along the surface.

例えば、表面シート１１は貼り合わされた２枚のシート材料により形成され、弾性部材２１がその２枚のシート材料の間に挟み込まれる。弾性部材２１の材料としては、通常の使い捨ておむつに使用される弾性伸縮材料（例えば、ポリウレタン糸、ポリウレタンフィルム、天然ゴム等）が用いられる。弾性部材２１の表面シート１１との接着は、伸張状態にあるときにホットメルト接着剤、熱溶着、超音波溶着等の貼着手段を用いて行われる。 For example, the top sheet 11 is formed of two sheet materials that are bonded together, and the elastic member 21 is sandwiched between the two sheet materials. As a material of the elastic member 21, an elastic stretchable material (for example, polyurethane yarn, polyurethane film, natural rubber, etc.) used for a normal disposable diaper is used. The elastic member 21 is bonded to the top sheet 11 using a bonding means such as a hot melt adhesive, heat welding, ultrasonic welding or the like when in the stretched state.

複数の切り込み列２２は、図６（ａ）に示すように、表面シート１１の収縮区間２３における隣接する弾性部材２１の各間の領域に前後方向Ｙに沿ってそれぞれ設けられている。各切り込み列２２は、前後方向Ｙに対して間隔をあけて設けられた複数の切り込み部２４を備えている。そして、その各切り込み部２４は、左右方向Ｘに間隔をあけ、かつ前後方向Ｙに沿って略直線状に設けられた２つのスリット２５を備えている。 As shown in FIG. 6A, the plurality of cut rows 22 are provided along the front-rear direction Y in regions between adjacent elastic members 21 in the contraction section 23 of the topsheet 11. Each cut row 22 includes a plurality of cut portions 24 provided at intervals with respect to the front-rear direction Y. Each of the cut portions 24 includes two slits 25 that are spaced in the left-right direction X and provided in a substantially linear shape along the front-rear direction Y.

このような表面シート１１の収縮区間２３の構成により、表面シート１１に対して前後方向Ｙの張力が付与されている場合には、その張力により伸張状態にある弾性部材２１の収縮が阻止され、収縮区間２３が前後方向Ｙに伸張された平坦な状態に保持される。 When the tension in the front-rear direction Y is applied to the topsheet 11 due to the configuration of the contraction section 23 of the topsheet 11, the contraction of the elastic member 21 in the stretched state is prevented by the tension, The contraction section 23 is held in a flat state extended in the front-rear direction Y.

しかし、その張力が解除されるのに伴って、図４、図５及び図６（ｂ）に示すように、弾性部材２１が収縮力により表面シート１１の収縮区間２３が部分的に前後方向Ｙに収縮される。これによって、各切り込み部２４の２つのスリット２５の間の部分２５ａが、開かれるるとともに、肌面側に立ち上がるように略弓状に変形する（以後、２つのスリット２５の間の部分２５ａを隆起部２５ａという）。その結果、収縮区間２３内に複数の開口部１２及び３次元的な凹凸構造１３が形成される。 However, as the tension is released, as shown in FIGS. 4, 5, and 6 (b), the elastic member 21 contracts the contraction section 23 of the topsheet 11 partially in the front-rear direction Y. Is shrunk. As a result, the portion 25a between the two slits 25 of each incision 24 is opened and deformed into a generally arcuate shape so as to rise to the skin surface side (hereinafter, the portion 25a between the two slits 25 is changed). Called a raised portion 25a). As a result, a plurality of openings 12 and a three-dimensional uneven structure 13 are formed in the contraction section 23.

凹凸構造１３の凹部は表面シート１１の平坦な部分によって構成され、凸部は、表面シート１１のその平坦な部分から肌面側に立ち上がったスリット２５の間の隆起部２５ａによって構成される。この隆起部２５ａは、前後方向Ｙの前側又は後側を向くようにして隆起するため、軟便に含まれる流動性の高い液体成分の前後方向Ｙへの流れを効果的に阻止することができる。なお、この開口部１２及び凹凸構造１３は、収縮区間２３が元の状態に伸張された場合には解消される。 The concave portion of the concavo-convex structure 13 is constituted by a flat portion of the topsheet 11, and the convex portion is constituted by a raised portion 25a between the slits 25 rising from the flat portion of the topsheet 11 to the skin surface side. Since the raised portion 25a is raised so as to face the front side or the rear side in the front-rear direction Y, it is possible to effectively prevent the flow of the liquid component having high fluidity contained in the soft stool in the front-rear direction Y. The opening 12 and the concavo-convex structure 13 are eliminated when the contraction section 23 is extended to the original state.

このような表面シート１１は、例えば透液性の不織布を用いて形成される。その不織布材料としては、親水性繊維（セルロース、レーヨン、コットン等）を用いて形成されたポイントボンド不織布、エアースルー不織布、又はスパンレース不織布等が用いられる。あるいは、疎水性繊維（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（商標）等）の表面を界面活性剤により処理して透水性とした不織布材料などを用いてもよい。 Such a surface sheet 11 is formed using a liquid-permeable nonwoven fabric, for example. As the nonwoven material, a point bond nonwoven fabric, an air-through nonwoven fabric, a spunlace nonwoven fabric or the like formed using hydrophilic fibers (cellulose, rayon, cotton, etc.) is used. Or you may use the nonwoven fabric material etc. which made the surface of hydrophobic fiber (a polypropylene, polyethylene, polyester, polyamide, nylon (trademark), etc.) water-permeable by processing with surfactant.

次に、表面シート１１の製造工程について簡単に説明する。まず、表面シート１１が前後方向Ｙに連続してなる連続体を、その収縮区間２３に対応する各部分に複数の弾性部材２１を伸張状態で挟み込むことにより形成する。続いて、弾性部材２１の伸張状態を維持しつつ、その連続体の収縮区間２３に対応する部分にカッターにより複数の切り込み列２２を形成する。続いて、その連続体を表面シート１１に対応する長さごとに切断し、それによって得られた表面シート１１を、おむつ本体の製造ラインに導入し、おむつ本体の肌面側にサイドシート１７と共に付与する。収縮区間２３は、切り込み列２２の形成後から表面シート１１がおむつ本体に付与されるまでのいずれかの工程で、図６（ａ）に示す伸張状態から図６（ｂ）等に示す収縮状態に移行される。すなわち、表面シート１１は、収縮区間２３が収縮された状態で、おむつの他の構成部材（例えば、吸収体１４及びバックシート１５）に接合される。 Next, the manufacturing process of the surface sheet 11 will be briefly described. First, a continuous body in which the surface sheet 11 is continuous in the front-rear direction Y is formed by sandwiching a plurality of elastic members 21 in each portion corresponding to the contraction section 23 in an expanded state. Subsequently, while maintaining the stretched state of the elastic member 21, a plurality of cut rows 22 are formed by a cutter in a portion corresponding to the contraction section 23 of the continuous body. Subsequently, the continuous body is cut into lengths corresponding to the surface sheet 11, and the surface sheet 11 obtained thereby is introduced into the production line of the diaper main body together with the side sheet 17 on the skin surface side of the diaper main body. Give. The contraction section 23 is a contracted state shown in FIG. 6 (b) or the like from the stretched state shown in FIG. 6 (a) in any process from the formation of the cut row 22 until the topsheet 11 is applied to the diaper body. It is transferred to. That is, the surface sheet 11 is joined to other components (for example, the absorber 14 and the back sheet 15) of the diaper in a state where the contraction section 23 is contracted.

このように複数の開口部１２及び３次元的な凹凸構造１３が構成された表面シート１１は、吸収体１４及びバックシート１５の積層構造よりも肌面側に位置して、表面に露出することになる。また、収縮区間２３は、着用者を基準として表面シート１１のやや後側に片寄った位置に設けられている。このため、表面シート１１に形成される複数の開口部１２及び３次元的な凹凸構造１３によって、着用者の腹部に不快感を与えることなく、着用者の軟便等の排泄物を確実に受け止めることができる。 Thus, the surface sheet 11 in which the plurality of openings 12 and the three-dimensional uneven structure 13 are configured is located on the skin side with respect to the laminated structure of the absorber 14 and the back sheet 15 and is exposed to the surface. become. Moreover, the shrinkage | contraction area 23 is provided in the position which shifted | deviated to the slightly rear side of the surface sheet 11 on the basis of the wearer. For this reason, the plurality of openings 12 and the three-dimensional concavo-convex structure 13 formed in the topsheet 11 reliably receive excrement such as soft stool of the wearer without causing discomfort to the wearer's abdomen. Can do.

この吸収性物品１の機能等について、この吸収性物品１の使用時に軟便等の液体成分と固定成分とを含む緩い排泄物が排泄された場合を例に説明する。このような緩い排泄物は、液体成分と固形成分とが混在した状態で流動しやすいため、吸収性物品１の前後方向Ｙへの拡散が特に問題となりやすい。 The function and the like of the absorbent article 1 will be described by taking, as an example, a case where loose excreta including a liquid component such as stool and a fixed component is excreted when the absorbent article 1 is used. Since such loose excrement tends to flow in a state where the liquid component and the solid component are mixed, diffusion of the absorbent article 1 in the front-rear direction Y is particularly problematic.

そこで、この吸収性物品１では、トップシートを構成する表面シート１１に複数の開口部１２及び３次元的な凹凸構造１３を設けることにより、緩い排泄物の拡散を抑制できるようになっている。すなわち、排泄物は、表面シート１１の複数の開口部１２及び３次元的な凹凸構造１３が付与された収縮区間２３により受け止められる。このとき、排泄物の流動成分は、凹凸構造１３を形成する隆起部２５ａにより、前後左右への広がりが効果的に堰き止められつつ、凹凸構造１３の凹部及び開口部１２により保持される。 Therefore, in this absorbent article 1, by providing a plurality of openings 12 and a three-dimensional uneven structure 13 on the top sheet 11 constituting the top sheet, it is possible to suppress the diffusion of loose excrement. That is, the excrement is received by the contraction section 23 provided with the plurality of openings 12 and the three-dimensional uneven structure 13 of the topsheet 11. At this time, the fluid component of the excrement is held by the recesses and the openings 12 of the concavo-convex structure 13 while the ridges 25a forming the concavo-convex structure 13 are effectively blocked from spreading in the front-rear and left-right directions.

また、表面シート１１の開口部１２を介して、あるいは表面シート１１を透過して表面シート１１の外面側に誘導された排泄物は、その液体成分が吸収体１４によって吸収されるとともに、その固形成分が表面シート１１と吸収体１４との間に確実に保持される。 In addition, the excrement guided through the opening 12 of the topsheet 11 or to the outer surface side of the topsheet 11 through the topsheet 11 is absorbed by the absorber 14 and its solids. The component is reliably held between the top sheet 11 and the absorbent body 14.

特に、本実施形態に係る構成では、隆起部２５ａが前後方向Ｙの前側又は後側を向くようにして隆起するため、軟便に含まれる流動性の高い液体成分の前後方向Ｙへの流れを効果的に阻止できるようになっている。 In particular, in the configuration according to the present embodiment, since the raised portion 25a is raised so as to face the front side or the rear side in the front-rear direction Y, the flow in the front-rear direction Y of the highly fluid liquid component contained in the soft stool is effective. Can be blocked.

以上のように、本実施形態によれば、吸収性物品１の肌面側に設けられた表面シート１１に形成された３次元的な凹凸構造１３によって、排泄物が広がるのを効果的に抑制できる。その結果、軟便等の排泄物が着用者の肌面の広範囲に付着するのを防止でき、排泄物の拭き取り作業の負担を軽減できる。 As described above, according to the present embodiment, the spread of excrement is effectively suppressed by the three-dimensional uneven structure 13 formed on the surface sheet 11 provided on the skin surface side of the absorbent article 1. it can. As a result, excrement such as loose stool can be prevented from adhering to a wide range of the skin surface of the wearer, and the burden of wiping off excrement can be reduced.

また、排泄物を３次元的な凹凸構造１３によって堰き止めることにより、排泄物の液体成分を吸収体１４により素早くかつ確実に捕捉できる。これによって、排泄物の漏れについてもより確実に防止できる。 In addition, the liquid component of the excrement can be quickly and reliably captured by the absorber 14 by damming the excrement with the three-dimensional uneven structure 13. Thereby, it is possible to more reliably prevent the leakage of excrement.

また、複数の弾性部材２１及び複数の切り込み列２２が設けられた表面シート１１を弾性部材２１の収縮力により収縮させるだけで、表面シート１１に複数の開口部１２及び３次元的な凹凸構造１３が形成されるため、３次元的な凹凸構造１３を形成するために表面シート１１に複雑な加工を施す必要がない。 Further, the surface sheet 11 provided with the plurality of elastic members 21 and the plurality of cut rows 22 is contracted by the contraction force of the elastic member 21, so that the surface sheet 11 has a plurality of openings 12 and a three-dimensional uneven structure 13. Therefore, in order to form the three-dimensional concavo-convex structure 13, it is not necessary to perform complicated processing on the top sheet 11.

また、複数の弾性部材２１及び複数の切り込み列２２の構成等を変更することにより、開口部１２及び３次元的な凹凸構造１３の形態を容易に変更できる。 Moreover, the form of the opening part 12 and the three-dimensional uneven | corrugated structure 13 can be easily changed by changing the structure of the some elastic member 21 and the some notch row | line | column 22, etc. FIG.

また、表面シート１１に形成された各切り込み部２４の２つのスリット１５によって、前後方向Ｙの前側又は後側を向くようにして隆起する隆起部２５ａが形成されるため、この隆起部２５ａによって、軟便に含まれる流動性の高い液体成分の前後方向Ｙへの流れを効果的に阻止できる。 In addition, the two slits 15 of each cut portion 24 formed in the top sheet 11 form a raised portion 25a that protrudes toward the front side or the rear side in the front-rear direction Y. The flow in the front-rear direction Y of the highly fluid liquid component contained in the soft stool can be effectively prevented.

また、表面シート１１が透液性の不織布で構成されているため、排泄物中の液体成分を素早く表面シート１１の外面側に透過させることができる。これによって、排泄物の拡散を抑制し、排泄物が着用者の肌面に付着する面積を抑制できる。 Moreover, since the surface sheet 11 is comprised with the liquid-permeable nonwoven fabric, the liquid component in excrement can be permeate | transmitted to the outer surface side of the surface sheet 11 quickly. Thereby, diffusion of excrement can be suppressed and the area where excrement adheres to the wearer's skin surface can be suppressed.

また、３次元的な凹凸構造１３等が設けられた表面シート１１がトップシートを兼ねているため、吸収性物品１を構成する部材の増加を抑制でき、製造工程の簡略化及び製造コストの低減が図れる。 Moreover, since the surface sheet 11 provided with the three-dimensional uneven structure 13 or the like also serves as a top sheet, an increase in members constituting the absorbent article 1 can be suppressed, and the manufacturing process is simplified and the manufacturing cost is reduced. Can be planned.

なお、本実施形態に係る吸収性物品１では、３次元的な凹凸構造１３等を有する表面シート１１がトップシートを兼ねた構成としたが、表面シート１１をトップシートと別部材の構成としてもよい。 In addition, in the absorbent article 1 which concerns on this embodiment, although the surface sheet 11 which has the three-dimensional uneven | corrugated structure 13 grade | etc., Was set as the top sheet, even if the surface sheet 11 is set as a structure separate from a top sheet. Good.

例えば、図７に示すように、表面シート１１をトップシート１９の肌面側に接合する構成が挙げられる。あるいは、図８に示すように、トップシート１９の前後方向Ｙの後よりの領域に穴あき部１９ａを設けるとともに、表面シート１１をトップシート１９の外面側に接合する構成が挙げられる。この図８の構成では、表面シート１１はトップシート１９と吸収体１４との間に配置され、表面シート１１に形成された複数の開口部１２及び３次元的な凹凸構造１３がトップシートの穴あき部１９ａを介して吸収性物品１の肌面側に露出する。この構成では、表面シート１１がトップシート１９と吸収体１４との間に配置されているため、表面シート１１の剥離又は脱落が生じるのを防止できる。 For example, as shown in FIG. 7, the structure which joins the surface sheet 11 to the skin surface side of the top sheet 19 is mentioned. Alternatively, as shown in FIG. 8, there is a configuration in which a holed portion 19 a is provided in a region behind the front-rear direction Y of the top sheet 19 and the topsheet 11 is joined to the outer surface side of the topsheet 19. In the configuration of FIG. 8, the topsheet 11 is disposed between the topsheet 19 and the absorber 14, and the plurality of openings 12 and the three-dimensional uneven structure 13 formed in the topsheet 11 are holes in the topsheet. It exposes to the skin surface side of the absorbent article 1 through the perforated part 19a. In this configuration, since the topsheet 11 is disposed between the topsheet 19 and the absorber 14, it is possible to prevent the topsheet 11 from being peeled off or dropped off.

まず図１４（ａ）に基づいて、表面シート１１の収縮区間２３が収縮する前の状態（伸張されている状態）の収縮区間２３の構成について説明する。図１４（ａ）に示すように、表面シート１１の収縮区間２３内には、複数の弾性部材３１及び複数の切り込み列３２が設けられている。複数の弾性部材３１は、糸状又は帯状の形態を有し、表面シート１１の収縮区間２３内において、左右方向Ｘに間隔をあけて、かつ、前後方向Ｙに沿って伸張された状態で表面シート１１に付与されている。なお、弾性部材３１の材料及び表面シート１１への挟込み構造等は、上述の第１実施形態の場合とほぼ同様である。 First, based on Fig.14 (a), the structure of the contraction area 23 of the state (expanded state) before the contraction area 23 of the surface sheet 11 contracts is demonstrated. As shown in FIG. 14A, a plurality of elastic members 31 and a plurality of cut rows 32 are provided in the contraction section 23 of the topsheet 11. The plurality of elastic members 31 have a thread-like or belt-like form, and are in the contracted section 23 of the topsheet 11 with a space in the left-right direction X and stretched along the front-back direction Y. 11. Note that the material of the elastic member 31 and the sandwiched structure of the top sheet 11 are substantially the same as those in the first embodiment.

複数の切り込み列３２は、図１４（ａ）に示すように、表面シート１１の収縮区間２３における隣接する弾性部材３１の各間の領域に前後方向Ｙに沿ってそれぞれ設けられている。各切り込み列３２は、前後方向Ｙに対して間隔をあけて設けられた複数の切り込み部３４を備えている。そして、その各切り込み部２４は、頂点部分３４ａが前後方向Ｙの前側又は後側（図１４（ａ）等に示す例では後側）を向けられた略山形の形状を有している。さらに、表面シート１１における各切り込み部３４の内側に位置する内側部分によって構成される起立部３５の自由端側の部分である先端部３５ａ（図１４（ａ）の破線によるハッチングを施した部分）に、起立部３５の接合用の接着剤（例えば、ホットメルト接着剤）が塗布される。 As shown in FIG. 14A, the plurality of cut rows 32 are respectively provided along the front-rear direction Y in regions between adjacent elastic members 31 in the contraction section 23 of the topsheet 11. Each incision row 32 includes a plurality of incisions 34 provided at intervals with respect to the front-rear direction Y. Each cut portion 24 has a substantially chevron shape in which the apex portion 34a faces the front side or the rear side in the front-rear direction Y (the rear side in the example shown in FIG. 14A, etc.). Furthermore, the front-end | tip part 35a which is a part by the side of the free end of the standing part 35 comprised by the inner part located inside each notch part 34 in the surface sheet 11 (part which gave the hatching by the broken line of Fig.14 (a)) Further, an adhesive (for example, a hot melt adhesive) for joining the upright portion 35 is applied.

このような収縮区間２３の構成により、表面シート１１に対する前後方向Ｙの張力が解除され、弾性部材３１が収縮するのに伴って、図９ないし図１３及び図１４（ｂ）に示すように、弾性部材３１が収縮力により表面シート１１の収縮区間２３が部分的に前後方向Ｙに収縮される。これによって、各切り込み部３４の内側部分である起立部３５が外面側に変位されることによって、複数の開口部１２及び３次元的な凹凸構造１３が形成される。この構成の場合、３次元的な凹凸構造１３の凸部は表面シート１１の平坦な部分（切り込み部３４の周辺部等）により構成され、凹部は弾性部材３１の収縮に伴って表面シート１１本体の外面側に変位された切り込み部３４の内側部分（起立部３５）により構成される。すなわち、切り込み部３４の内側部分は、開口部１２と凹凸構造１３の凹部を兼ねている。 With such a configuration of the contraction section 23, the tension in the front-rear direction Y with respect to the topsheet 11 is released, and as the elastic member 31 contracts, as shown in FIGS. 9 to 13 and 14 (b), The contraction section 23 of the top sheet 11 is partially contracted in the front-rear direction Y by the elastic member 31 contracting force. As a result, the upright portions 35, which are the inner portions of the notches 34, are displaced to the outer surface side, whereby the plurality of openings 12 and the three-dimensional uneven structure 13 are formed. In the case of this configuration, the convex portion of the three-dimensional concavo-convex structure 13 is constituted by a flat portion (peripheral portion of the cut portion 34) of the topsheet 11, and the concave portion is the topsheet 11 main body as the elastic member 31 contracts. It is comprised by the inner part (stand part 35) of the notch part 34 displaced to the outer surface side. That is, the inner portion of the cut portion 34 serves as the opening 12 and the recess of the concavo-convex structure 13.

そして、このように収縮区間２３が収縮されて表面シート１１が吸収体１４等と接合されるのに伴って、各起立部３５の先端部３５ａが表面シート１１の外面側に位置する部材（例えば、吸収体１４）に接合される。このとき、各起立部３５は前後方向Ｙの前側又は後側を向くようにして起立され、その起立された状態のままその先端部３５ａが吸収体１４等に接合される。 As the contraction section 23 is contracted in this way and the topsheet 11 is joined to the absorber 14 or the like, a member (for example, a front end portion 35a of each standing portion 35 is positioned on the outer surface side of the topsheet 11 (for example, To the absorber 14). At this time, each standing portion 35 is erected so as to face the front side or the rear side in the front-rear direction Y, and the tip portion 35a is joined to the absorber 14 or the like in the erected state.

また、表面シート１１の収縮区間２３収縮されて収縮区間２３が表面シート１１の外面側に位置する部材（例えば、吸収体１４）から肌面側に浮き上がった際に、起立部３５の先端部３５ａがその外面側の部材と接合されているため、表面シート１１とその外面側の部材との間に適度な隙間が形成される。 Further, when the contraction section 23 of the surface sheet 11 is contracted and the contraction section 23 is lifted to the skin surface side from a member (for example, the absorbent body 14) located on the outer surface side of the surface sheet 11, the tip portion 35 a of the standing portion 35. Is joined to the outer surface side member, an appropriate gap is formed between the topsheet 11 and the outer surface side member.

また、表面シート１１の各起立部３５の先端部３５ａが表面シート１１の外面側に位置する部材（例えば、吸収体１４）に接合されているため、起立部３５の起立姿勢を確実に保持できる。このため、表面シート１１の起立部３５によって、表面シート１１の外面側に誘導された軟便等の排泄物をより確実に堰き止めることができる。 Moreover, since the front-end | tip part 35a of each standing part 35 of the surface sheet 11 is joined to the member (for example, absorber 14) located in the outer surface side of the surface sheet 11, the standing posture of the standing part 35 can be hold | maintained reliably. . For this reason, excrement such as loose stool guided to the outer surface side of the topsheet 11 can be more reliably dammed by the standing portion 35 of the topsheet 11.

また、収縮区間２３の収縮に伴い、表面シート１１とその外面側の部材（例えば、吸収体１４）との間に適度な隙間が形成されるため、開口部１２を介して表面シート１１の外面側に誘導された軟便等の収容能力を向上できる。 Further, as the contraction section 23 contracts, an appropriate gap is formed between the topsheet 11 and the outer surface side member (for example, the absorber 14), and therefore the outer surface of the topsheet 11 through the opening 12. The capacity of loose stool or the like guided to the side can be improved.

なお、本実施形態に係る表面シート１１についても、上述の図７及び図８に示す構成を採用してもよい。 In addition, you may employ | adopt the structure shown in the above-mentioned FIG.7 and FIG.8 also about the surface sheet 11 which concerns on this embodiment.

また、上述の第１及び第２実施形態では表面シート１１を透液性の不織布で構成したが、表面シート１１を撥水性の不織布、あるいは透孔を有するプラスチックフィルムなどを用いて構成してもよい。この場合、一旦表面シート１１の外面側に誘導された排泄物の液体成分が表面シート１１を透過して肌面側に逆戻りするのを抑制できる。これによって、逆戻りした排泄物の液体成分が着用者の肌に付着して不快感を与えるのを防止できる。 In the first and second embodiments described above, the topsheet 11 is made of a liquid-permeable nonwoven fabric. However, the topsheet 11 may be made of a water-repellent nonwoven fabric or a plastic film having through holes. Good. In this case, it is possible to prevent the liquid component of excrement once induced to the outer surface side of the surface sheet 11 from passing through the surface sheet 11 and returning to the skin surface side. Thereby, it can prevent that the liquid component of the excrement which turned backward adheres to a wearer's skin, and gives discomfort.
