The leak-proof layer F is composed of a liquid-impermeable back sheet 3. The absorber 4 is interposed between the top sheet 2 and the back sheet 3.

表面シート2は、吸収体4の上面の全域を被覆し且つ吸収体4の側縁を覆って裏面シート側へ巻き込まれている。裏面シート3は、吸収体4の下面を被覆している。裏面シート3は、吸収体4の側縁から外方に延出してサイドフラップ6を形成している。サイドフラップ6は、ナプキン1の排泄部対向部Aの位置において更に外方へ延出しており一対のウイング7を形成している。表面シート2及び裏面シート3はそれぞれ吸収体4の前後端から延出し、その延出部分において互いに接合されてエンドシール部8を形成している。吸収体4の表面シート2側には、吸収体4と表面シート2とが一体的に圧密化されて形成された防漏溝8が形成されている。   The top sheet 2 covers the entire upper surface of the absorbent body 4 and covers the side edges of the absorbent body 4 and is wound around the back sheet side. The back sheet 3 covers the lower surface of the absorber 4. The back sheet 3 extends outward from the side edge of the absorber 4 to form side flaps 6. The side flaps 6 further extend outward at the position of the excretory part facing part A of the napkin 1 to form a pair of wings 7. The top sheet 2 and the back sheet 3 respectively extend from the front and rear ends of the absorber 4 and are joined to each other at the extended portions to form an end seal portion 8. On the surface sheet 2 side of the absorbent body 4, a leak-proof groove 8 is formed, which is formed by integrally compacting the absorbent body 4 and the surface sheet 2.

生理用ナプキン1は、その長手方向に、着用時に着用者の液排泄部に対向配置される部位である排泄部対向部Aと、着用時に排泄部対向部Aよりも着用者の背側(後方)に配される後方部Bと、ナプキン1の前端部及び後端部をそれぞれ形成する前端部C及び後端部Dとを有している。
本実施形態における排泄部対向部Aと後方部Bとの境界は、ナプキン1の長さ方向の略中央部に存する。本実施形態における各ウイング7は、着用時に、折り曲げられてショーツ等の下着の外表面に粘着剤等により固定される。第1及び第3実施形態のナプキンにおける後方部Bは、ナプキン後端側のウイング基端部71(図1参照)から2cm以上、好ましくは3cm以上離間した部位である。図1に、後方部Bとウイング基端部71との離間距離を符号Lで示した。
The sanitary napkin 1 includes, in its longitudinal direction, an excretion portion facing portion A that is a portion disposed opposite to the wearer's liquid excretion portion when worn, and the wearer's dorsal side (backward) from the excretion portion facing portion A when worn. ) And a front end C and a rear end D that form a front end and a rear end of the napkin 1, respectively.
The boundary between the excretory part facing part A and the rear part B in the present embodiment exists in a substantially central part of the napkin 1 in the length direction. Each wing 7 in the present embodiment is bent and fixed to the outer surface of an underwear such as shorts with an adhesive or the like when worn. The rear part B in the napkin of the first and third embodiments is a part that is separated from the wing base end part 71 (see FIG. 1) on the rear end side of the napkin by 2 cm or more, preferably 3 cm or more. In FIG. 1, the distance between the rear portion B and the wing base end portion 71 is indicated by a symbol L.

ナプキン1の長手方向の両側部には、その長手方向に沿って一対の防漏壁5,5が配されている。防漏壁5は、ナプキン1の前後端部C,D間に亘って配されている。   A pair of leak-proof walls 5 and 5 are arranged on both sides of the napkin 1 in the longitudinal direction along the longitudinal direction. The leak-proof wall 5 is disposed between the front and rear end portions C and D of the napkin 1.

防漏壁5は、図2に示すように、吸収体4の側縁の近傍から起立した基壁部51とその上端部に連設された面状の弾性伸縮部52とからなる。弾性伸縮部52には、ナプキン1の長手方向に沿って弾性部材9が配されて弾性伸縮性が付与されている。
防漏壁5は、表面シート2及び吸収体4からなる吸収層Eの長手方向の両側縁に沿って設されており、弾性伸縮部52の上面(肌当接面)は、該吸収層4の上面(肌当接面)と略平行である。
そして、弾性伸縮部52は、少なくとも排泄部対向部Aにおいて着用者の肌に面状に当接する。
As shown in FIG. 2, the leak-proof wall 5 is composed of a base wall portion 51 erected from the vicinity of the side edge of the absorber 4 and a planar elastic stretchable portion 52 that is connected to the upper end portion thereof. The elastic member 52 is provided with an elastic member by being provided with an elastic member 9 along the longitudinal direction of the napkin 1.
The leak-proof wall 5 is provided along both side edges in the longitudinal direction of the absorbent layer E composed of the topsheet 2 and the absorbent body 4, and the upper surface (skin contact surface) of the elastic stretchable part 52 is the absorbent layer 4. Is substantially parallel to the upper surface (skin contact surface).
And the elastic expansion-contraction part 52 contact | abuts a wearer's skin at planar shape in the excretion part opposing part A at least.

弾性伸縮部52は、基壁部51の上端部Pに断面T字状に連設されている。即ち、弾性伸縮部52は、基壁部51の上端部Pからナプキン1の幅方向内方に張り出す内方張出部52aと、該上端部Pからナプキン1の幅方向外方に張り出す外方張出部52bとから構成されている。両張出部52a,52bの張り出し幅は、ほぼ同一であり、両張出部52a,52bそれぞれには、糸状の弾性部材9が3本づつ間隔を開けて配設されている。弾性部材9は、少なくともナプキン1の排泄部対向部A及び後方部Bに配されている。   The elastic stretchable part 52 is connected to the upper end part P of the base wall part 51 in a T-shaped cross section. That is, the elastic expansion / contraction part 52 projects inwardly in the width direction of the napkin 1 from the upper end part P of the base wall part 51, and projects inward in the width direction of the napkin 1 from the upper end part P. It is comprised from the outward projecting part 52b. The projecting widths of the two projecting portions 52a and 52b are substantially the same, and three thread-like elastic members 9 are arranged at intervals of both projecting portions 52a and 52b. The elastic member 9 is disposed at least in the excretory part facing part A and the rear part B of the napkin 1.

本実施形態のナプキン1における防漏壁5は、排泄部対向部A及び後方部Bにおいては起立しており、且つ前端部C及び後端部Dにおいては、少なくとも弾性伸縮部52の幅方向内側(内方張出部52a)が表面シート2に固定されることで起立が阻害されている(起立していない)。
また、弾性伸縮部52は、防漏壁5が起立した領域(弾性伸縮部の幅方向内側が表面シート2上に固定されていない領域)の長手方向の両端それぞれの外方において表面シート2及びエンドシール部8に固定されており、弾性伸縮部52の収縮によって、ナプキン1は、その長手方向の全体形状が図3に示すように凹状に湾曲している。
The leak-proof wall 5 in the napkin 1 of the present embodiment stands up at the excretory part facing part A and the rear part B, and at least the inner side in the width direction of the elastic stretchable part 52 at the front end part C and the rear end part D. The (inwardly projecting portion 52a) is fixed to the top sheet 2 so that the standing is inhibited (not standing).
Further, the elastic stretchable part 52 is formed by the topsheet 2 and the outside of each end in the longitudinal direction of the region where the leak-proof wall 5 stands (the region where the inner side in the width direction of the elastic stretchable part is not fixed on the topsheet 2). The napkin 1 is fixed to the end seal portion 8, and the overall shape in the longitudinal direction of the napkin 1 is concavely curved as shown in FIG.

本実施形態のナプキン1における防漏壁5は、後方部Bにおける基壁部51の上端部Pから裏面シート(防漏層)3までの距離(自然状態における直線距離,図2(b)参照)L2が、排泄部対向部Aにおける該距離〔図2(a)参照〕L1よりも短い。   The leak-proof wall 5 in the napkin 1 of this embodiment is the distance from the upper end part P of the base wall part 51 in the back part B to the back surface sheet (leak-proof layer) 3 (a linear distance in a natural state, see FIG. 2B). ) L2 is shorter than the distance L1 in the excretory part facing part A [see FIG.

本実施形態のナプキンによれば、排泄部対向部A及び後方部Bにおいて防漏壁5が起立しているため、下記効果が奏される。
(1)排泄部対向部Aに排泄された液が後方に流れた場合においても、後方部Bにおける防漏壁5により、その液が横方向から漏れ出すことが防止される。
(2)排泄部対向部Aに排泄された液が横方向に流れた場合においても、防漏壁5を乗り越えずに後方部に流れ、その近傍の吸収体に吸収されるので、吸収体の吸収性能が効率的に活用されて漏れが防止される。斯かる効果は、防漏壁5が、排泄部対向部Aから後方部Bに亘って連続して起立している場合に、一層顕著に発現される。
According to the napkin of this embodiment, since the leak-proof wall 5 stands up in the excretion part opposing part A and the back part B, the following effect is show | played.
(1) Even when the liquid excreted in the excretory part facing part A flows rearward, the leak-proof wall 5 in the rear part B prevents the liquid from leaking from the lateral direction.
(2) Even when the liquid excreted in the excretory part facing part A flows in the lateral direction, it flows to the rear part without getting over the leak-proof wall 5 and is absorbed by the absorber in the vicinity thereof. Absorption performance is efficiently utilized to prevent leakage. Such an effect is more prominently exhibited when the leak-proof wall 5 stands up continuously from the excretory part facing part A to the rear part B.

更に、本実施形態のナプキンによれば、後方部Bにおける前記距離L2が排泄部対向部Aにおける前記距離L1よりも短いため、下記効果が奏される。
(3)ナプキン1のフィット性(特に着用者のお尻乃至お尻寄り部分に対するフィット性)が良好となり、ナプキンと身体とが無理なくフィットし、違和感が低減される。
即ち、液排泄部での身体のライン(カーブ)とそれよりも後ろ側(お尻側)のライン(カーブ)は一定ではなく、その曲率は液排泄部の方が小さい。本実施形態では、後方部Bにおける前記距離L2を排泄部対向部Aにおける前記距離L1よりも短くしたため、後方部Bにおけるナプキンの湾曲の程度(曲率)と排泄部対向部Aにおけるナプキンの湾曲の程度(曲率)とを容易且つ効果的に異ならせることができ、ナプキンの全体形状を、身体の曲面形状に一層フィットした形状とすることができる。
Furthermore, according to the napkin of this embodiment, since the distance L2 in the rear part B is shorter than the distance L1 in the excretory part facing part A, the following effects are exhibited.
(3) The fit of the napkin 1 (especially the fit to the wearer's buttocks or close to the buttocks) becomes good, the napkin and the body fit comfortably, and the uncomfortable feeling is reduced.
That is, the body line (curve) in the liquid excretion part and the line (curve) on the rear side (butt side) are not constant, and the curvature is smaller in the liquid excretion part. In the present embodiment, the distance L2 in the rear part B is shorter than the distance L1 in the excretory part facing part A. The degree (curvature) can be easily and effectively varied, and the overall shape of the napkin can be made to be a shape that more closely matches the curved shape of the body.

尚、後方部の防漏性を高めようとして、単に弾性伸縮性を有する防漏壁を後方部にも設けた場合には、後方部におけるナプキン(吸収性物品)の湾曲の程度が大きくなり過ぎて却ってフィット性が低下する。このような理由から、従来の吸収性物品においては、後方部に防漏壁が設けられることがなかったが、本発明においては、排泄部対向部と後方部とで防漏壁の高さを異ならせることにより、フィット性と防漏性とを両立させることを可能とした。   If a leak-proof wall having elastic elasticity is also provided in the rear part in order to improve the leak-proof characteristic in the rear part, the degree of curvature of the napkin (absorbent article) in the rear part becomes too large. On the contrary, the fit is reduced. For this reason, in the conventional absorbent article, the leakage preventing wall is not provided in the rear part, but in the present invention, the height of the leakage preventing wall is increased between the excretion part facing part and the rear part. By making it different, it was possible to achieve both fit and leakproofness.

特に、本実施形態の防漏壁5は、内方張出部52a及び外方張出部52bを有する断面T字状の形態を有するため、更に下記効果(4)が奏される。
(4)防漏壁の上端部(弾性伸縮部52)が面状であることによって、身体とのフィット性が向上するばかりでなく、防漏壁の形状安定性が良くなり、上述したような漏れ防止効果が良好となる。
In particular, since the leak-proof wall 5 of the present embodiment has a T-shaped cross section having an inwardly extending portion 52a and an outwardly extending portion 52b, the following effect (4) is further achieved.
(4) The upper end portion (elastic elastic part 52) of the leak-proof wall has a planar shape, which not only improves the fit with the body but also improves the shape stability of the leak-proof wall, as described above. Leak prevention effect is improved.

前記効果(1)〜(3)を確実に発現させる観点から、排泄部対向部Aにおける基壁部51の上端部Pから裏面シート(防漏層)3までの距離L1と、後方部Bにおける基壁部51の上端部Pから裏面シート(防漏層)3までの距離L2との比(L1/L2)は、1.2〜6.0であり、1.5〜3.0であることが好ましい。 From the viewpoint of reliably expressing the effects (1) to (3), the distance L1 from the upper end portion P of the base wall portion 51 to the back sheet (leak-proof layer) 3 in the excretory portion facing portion A and the rear portion B Ratio (L1 / L2) with distance L2 from upper end part P of base wall part 51 to back sheet (leak-proof layer) 3 is 1.2-6.0 , and is 1.5-3.0. It is preferable.

また、液排泄部付近の漏れ防止の観点から、前記距離L1は5〜50mm、特に10〜40mmであることが好ましく、フィット性、使用感及び漏れ防止の観点から、前記距離L2は2〜40mm、特に5〜30mmであることが好ましい。更に、弾性伸縮部52の幅〔内方張出部52aの先端と、外方張出部52bの先端との間の距離〕W〔図2(a)参照〕は6〜40mm、特に10〜30mmであることが身体とのフィット性と横漏れ防止効果の観点から好ましい。   Further, from the viewpoint of preventing leakage near the liquid excretion part, the distance L1 is preferably 5 to 50 mm, particularly preferably 10 to 40 mm. From the viewpoint of fit, usability, and leakage prevention, the distance L2 is 2 to 40 mm. In particular, 5 to 30 mm is preferable. Further, the width of the elastic stretchable portion 52 [the distance between the tip of the inwardly extending portion 52a and the tip of the outwardly extending portion 52b] W (see FIG. 2A) is 6 to 40 mm, particularly 10 to 10 mm. It is preferable that it is 30 mm from a viewpoint of the fitting property with a body and the side leakage prevention effect.

本実施形態における防漏壁5は、図4に示すような、長手方向に亘って一定の幅W2を有する基壁部形成用シート部53と該基壁部形成シート部53の幅方向の一端部54に断面T字状に連設された弾性伸縮部52とからなる弾性伸縮部材50を、ナプキン1の他の構成部材(表面シート2や裏面シート3等)に固定して形成されている。
尚、基壁部形成シート部の幅方向とは、長手方向及び幅方向を有する基壁部形成用シート部の幅方向であって、ナプキン(吸収性物品)の幅方向とは意味が異なる。

また、後方部Bにおける基壁部形成用シート部53の一部には重層部58が形成されている。重層部58は、基壁部形成用シート部53の一部に設けられたものであり、基壁部形成用シート部53の一部を少なくとも2重になるように折り曲げ、その折り曲げた状態を、接着剤、ヒートシール等の接合手段により維持した部分であるが、図6(a)や図に示されるような、基壁部形成用シート部53を折り曲げて重層させた部分に弾性伸縮部までが固定されている場合の該重層部分は含まない。
On the other hand, in the rear portion B, the base wall portion forming sheet portion 53 of the elastic stretchable member 50 is between the one end portion 54 and the other end portion 55 as shown in FIG. At a position near the one end portion 54, the absorber 4 is fixed to the upper surface side of the absorber 4 by a known joining means such as a heat seal 13.

And the distance from the lower end Q of the base wall 51 in the rear part B to the upper end P is shorter than the distance in the excretory part facing part A, so that from the upper end P of the base wall 51 Since the distance L2 in the rear part B to the back sheet (leakproof layer) 3 is shorter than the distance L1 in the excretory part facing part A, the width of the base wall part forming sheet part changes in the longitudinal direction. Manufacture is easy compared with the case where an elastic expansion-contraction member is fixed, Moreover, the distance L2 in the back part C from the upper end part P of a base wall part to a back surface sheet (leak-proof layer) 3 is the excretion part opposing part A. And stably formed below the distance L1 It is possible.

本実施形態のナプキン1においては、図1及び図3に示すように、ナプキン1の長手方向における後端部Dの肌当接面側に防漏シート10が配されており、該防漏シート10は、起立した防漏壁5の弾性伸縮部52に固定されて、そのナプキン1の長手方向中央側の縁部10aが、表面シート(吸収層)2から離間している。   In the napkin 1 of this embodiment, as shown in FIG.1 and FIG.3, the leak-proof sheet 10 is distribute | arranged to the skin contact surface side of the rear-end part D in the longitudinal direction of the napkin 1, and this leak-proof sheet 10 is fixed to the elastic expansion / contraction part 52 of the standing leak-proof wall 5, and the edge part 10 a on the center side in the longitudinal direction of the napkin 1 is separated from the surface sheet (absorbing layer) 2.

斯かる防漏シート10を配設することで、後部にポケット状の空間ができ、後ろに流れてきた液が漏れ出すことを防止することができる。このポケットは防漏壁の弾性伸縮部に固定してあるため、防漏壁が起立(少なくとも幅方向内方側の縁部が表面シートから離間)することに連動して表面シートから離間して形成されているため潰れにくい。
尚、防漏シート10は、ナプキンの幅方向の両端部近傍においては、図1中に符号11で示す箇所に公知の接合手段(接着剤、ヒートシール等)により固定されており、ナプキンの長手方向においては、エンドシール部8に一体的に固定されている。
By providing such a leak-proof sheet 10, a pocket-like space is formed at the rear, and the liquid flowing behind can be prevented from leaking. Since this pocket is fixed to the elastic expansion / contraction part of the leak-proof wall, it is separated from the surface sheet in conjunction with the leak-proof wall standing up (at least the edge on the inner side in the width direction is separated from the surface sheet). Because it is formed, it is hard to be crushed.
The leak-proof sheet 10 is fixed by a known joining means (adhesive, heat seal, etc.) at a position indicated by reference numeral 11 in FIG. 1 in the vicinity of both ends in the width direction of the napkin, and the length of the napkin In the direction, the end seal portion 8 is integrally fixed.

A step of fixing the base wall portion forming sheet portion 53 in the rear portion B to the both side portions of the main body so that the fixing position in the width direction is different; It can be manufactured through a fixing step, a step of fixing the leak-proof layer F to the main body made of the absorption layer E, and the like.

基壁部形成用シート部53を該本体の両側部に固定する工程においては、基壁部形成用シート部の端部55又はその近傍を、該本体における排泄部対向部A及び後方部Bを形成する部分に固定した後、その固定した端部55又はその近傍以外の部位を、該本体における後方部Bを形成する部分に固定しても良いし、その逆の順序で固定しても良い。
また、前記重層部58は、基壁部形成用シート部53を前記本体に固定する工程において形成することもできるが、弾性伸縮部材50を製造する工程において、基壁部形成用シート部53における後方部Bに配される部分に形成することが好ましい。また、吸収層E及び防漏層(裏面シート3)Fからなる本体を製造し、該本体の吸収層E及び/又は防漏層Fに、基壁部形成用シート部53を固定しても良い。この場合、端部55は、図2のように吸収層Eの下ではなく、吸収層Eより幅方向外方に延出した防漏層Fに固定される。
In the step of fixing the base wall portion forming sheet portion 53 to both side portions of the main body, the end portion 55 of the base wall portion forming sheet portion or the vicinity thereof is connected to the excretory portion facing portion A and the rear portion B of the main body. After fixing to the portion to be formed, the fixed end portion 55 or a portion other than the vicinity thereof may be fixed to the portion forming the rear portion B in the main body, or may be fixed in the reverse order. .
The multilayer portion 58 can also be formed in the step of fixing the base wall portion forming sheet portion 53 to the main body, but in the step of manufacturing the elastic stretchable member 50, the base wall portion forming sheet portion 53 It is preferable to form in the part distribute | arranged to the back part B. FIG. Moreover, even if a main body composed of the absorption layer E and the leak-proof layer (back sheet 3) F is manufactured and the base wall portion forming sheet portion 53 is fixed to the absorption layer E and / or the leak-proof layer F of the main body, good. In this case, the end portion 55 is fixed not to the bottom of the absorption layer E as shown in FIG. 2 but to the leakage preventing layer F extending outward in the width direction from the absorption layer E.

本実施形態の生理用ナプキンの形成材料について説明すると、表面シート2、吸収体、裏面シート3、防漏シート10、防漏壁5形成用の弾性伸縮部材50を構成するシート材及び弾性部材9としては、それぞれ、生理用ナプキン、失禁パッド等の吸収性物品に従来用いられている材料を特に制限なく用いることができる。尚、裏面シートは、単層シートでも積層シートでも良く、積層シートは、液不透過性のシートと液透過性のシートとの積層体であっても良い。
弾性伸縮部52は、弾性部材9を用いず、伸縮性のあるフィルムや不織布、伸縮性のあるフィルムと不織布とのラミネート材料、伸縮性のないフィルムに凹凸加工により伸縮性を付与した材料等で構成されていても良い。また、基壁部も弾性伸縮部と同様に伸縮性を有していても良い。また、本実施形態における防漏壁は、基壁部形成用シート部と弾性伸縮部とが一体的に連設された弾性伸縮部材で形成されているが、基壁部形成用シート部と弾性伸縮部とを別々に製造し、それらを接合して得られた弾性伸縮部材を用いて形成することもできる。
The material for forming the sanitary napkin of the present embodiment will be described. The sheet material and the elastic member 9 that constitute the elastic sheet 50 and the elastic sheet 50 for forming the top sheet 2, the absorbent body, the back sheet 3, the leak-proof sheet 10, and the leak-proof wall 5. In particular, materials conventionally used for absorbent articles such as sanitary napkins and incontinence pads can be used without particular limitation. The back sheet may be a single-layer sheet or a laminated sheet, and the laminated sheet may be a laminate of a liquid-impermeable sheet and a liquid-permeable sheet.
The elastic stretchable part 52 does not use the elastic member 9 and is made of a stretchable film or nonwoven fabric, a laminate material of a stretchable film and a nonwoven fabric, a material imparted with stretchability by uneven processing on a non-stretchable film, or the like. It may be configured. Further, the base wall portion may also have stretchability like the elastic stretchable portion. In addition, the leak-proof wall in the present embodiment is formed of an elastic expansion / contraction member in which a base wall portion forming sheet portion and an elastic expansion / contraction portion are integrally connected, but the base wall portion forming sheet portion is elastic. It can also be formed using an elastic elastic member obtained by separately manufacturing the elastic part and joining them.

次に、本発明の第2実施形態としての生理用ナプキン1’について、図5〜図7を参照して説明する。第2実施形態の生理用ナプキン1’については、上述した生理用ナプキン1と異なる点について説明し、同様の点については説明を省略する。特に説明しない点については、上述した生理用ナプキン1についての説明が適宜適用される。   Next, a sanitary napkin 1 ′ as a second embodiment of the present invention will be described with reference to FIGS. 5 to 7. Regarding the sanitary napkin 1 ′ of the second embodiment, the differences from the sanitary napkin 1 described above will be described, and description of similar points will be omitted. For the points that are not particularly described, the above description of the sanitary napkin 1 is appropriately applied.

第2実施形態の生理用ナプキン1’における防漏壁5は、図5及び図7に示すように、排泄部対向部Aと後方部Bとの間に、該防漏壁5が起立していない中央固定部56を有している。中央固定部56においては、図6(a)に示すように、弾性伸縮部52が幅方向のほぼ全域に亘って、ヒートシール13等の公知の接合手段により表面シート2又は裏面シート3に固定されることで起立が阻害されている(起立していない)。また、図6(b)に示すように、後方部Bにおける基壁部形成用シート部53の一部には重層部58が形成されている。
尚、中央固定部56における弾性伸縮部52は、その幅方向内側(内方張出部52a)のみを表面シート2に固定することもできる。
The leak-proof wall 5 in the sanitary napkin 1 ′ of the second embodiment has the leak-proof wall 5 standing between the excretory part facing part A and the rear part B as shown in FIGS. 5 and 7. There is no central fixing part 56. In the center fixing portion 56, as shown in FIG. 6A, the elastic stretchable portion 52 is fixed to the top sheet 2 or the back sheet 3 by a known joining means such as a heat seal 13 over almost the entire width direction. In doing so, standing is inhibited (not standing). Further, as shown in FIG. 6B, a multilayer portion 58 is formed on a part of the base wall portion forming sheet portion 53 in the rear portion B.
In addition, the elastic expansion-contraction part 52 in the center fixing | fixed part 56 can also fix only the width direction inner side (inward protrusion part 52a) to the surface sheet 2. FIG.

第2実施形態の生理用ナプキン1’によれば、第1実施形態と同様の作用効果が奏されるのに加えて、中央固定部56を有するため、排泄部対向部Aの領域の弾性部材の伸縮応力を後方部Bの領域に伝えないために、より横漏れ防止と後ろ方向の漏れ防止とがそれぞれ互いに影響されることなく発現される。即ち、足の歩伏や開閉動作により排泄部対向部Aの弾性伸縮部が応力を受けても、中央固定部56の存在により後方部Bまで応力が伝わらない。従って、足の動作によらず後方部Bの防漏壁5を安定に保つことができる。   According to the sanitary napkin 1 ′ of the second embodiment, in addition to having the same operational effects as the first embodiment, the elastic member in the region of the excretory part-facing part A has the central fixing part 56. In order not to transmit the expansion / contraction stress to the region of the rear portion B, the lateral leakage prevention and the backward leakage prevention are expressed without being influenced by each other. That is, even if the elastic expansion / contraction part of the excretory part facing part A receives stress due to the yielding or opening / closing operation of the foot, the stress is not transmitted to the rear part B due to the presence of the central fixing part 56. Therefore, the leak-proof wall 5 at the rear portion B can be kept stable regardless of the motion of the foot.

また、第2実施形態の生理用ナプキン1’においては、図6(b)に示すように、後方部Bにおける弾性伸縮部52の幅方向外方側の側縁部57が、吸収体4の側縁部よりも外方に延出した裏面シート3(サイドフラップ6)上に固定されている。
これにより、弾性伸縮部52の幅方向内方側(内方張出部52a)を確実に立ち上がらせることができ、弾性伸縮部52と表面シート2との間に形成されるポケットが着用中に装着圧が掛かっても潰れにくい。更に外方張出部52bが裏面シート33と接着しているために液の滲み漏れが更に低減できる。
Further, in the sanitary napkin 1 ′ of the second embodiment, as shown in FIG. 6B, the side edge 57 on the outer side in the width direction of the elastic stretchable part 52 in the rear part B is It is fixed on the back sheet 3 (side flap 6) extending outward from the side edge.
Thereby, the width direction inner side (inwardly projecting portion 52a) of the elastic stretchable portion 52 can be reliably raised, and the pocket formed between the elastic stretchable portion 52 and the topsheet 2 is being worn. Even if wearing pressure is applied, it is hard to collapse. Furthermore, since the outward projecting portion 52b is bonded to the back sheet 33, leakage of the liquid can be further reduced.

本発明は、前記各実施形態に制限されるものではなく、本発明の趣旨を逸脱しない範囲において種々変形可能である。   The present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention.

例えば、T字型の防漏壁を採用する場合、内方張出部52a及び外方張出部52bそれぞれの張り出し幅は同一でも異なっていても良い。外方張出部52bの方が張り出し幅が大きくても良い。更に防漏壁は、図に示すような断面形状であっても良い。図中、符号12はシート同士を接合するための接着剤である。 For example, when a T-shaped leak-proof wall is employed, the projecting widths of the inward projecting portion 52a and the outward projecting portion 52b may be the same or different. The overhanging portion 52b may have a larger overhanging width. Further leakage preventing wall may be a cross-sectional shape as shown in FIG. In Figure 9, reference numeral 12 is Ru adhesive der for joining the sheets together.

また、前記各実施形態のナプキンにおいては、基壁部形成用シート部の幅が長手方向に亘って均一な弾性伸縮部材を用いて防漏壁を形成していたが、後方部における基壁部形成用シート部の材料自体の幅を、排泄部対向部Aにおける基壁部形成用シート部の材料の幅より短くしても良い。
また、防漏壁は、基壁部形成用シート部の幅方向の固定位置を調節したり、重層部の幅や接合の幅、又は重層部におけるシートの重層回数を多くすることにより、後方部Bにおいて、前記距離L2が後端部Dに向かうに従って減少するようにしても良い。
Moreover, in the napkin of each said embodiment, although the leak-proof wall was formed using the elastic expansion-contraction member where the width | variety of the sheet | seat part for base wall part formation was uniform over the longitudinal direction, the base wall part in a back part The width of the material of the forming sheet part itself may be shorter than the width of the material of the base wall part forming sheet part in the excretory part facing part A.
In addition, the leak-proof wall can be adjusted by adjusting the fixing position in the width direction of the base wall forming sheet portion, increasing the width of the multi-layer portion, the width of joining, or increasing the number of times the sheets are stacked in the multi-layer portion. In B, the distance L2 may decrease as it goes toward the rear end D.

た、第1実施形態のナプキン1においては、長手方向における後端部Dに防漏シート10が前述した態様で配設されているが、このような防漏シートは、ナプキンの前端部C、又は前端部C及び後端部Dの両方に設けることもできる。 Also, in the napkin 1 of the first embodiment, the barrier sheet 10 in the rear portion D in the longitudinal direction are arranged in the manner described above, such leak-barrier sheet, the front end portion C of the napkin Alternatively, it may be provided at both the front end C and the rear end D.

一の実施形態における説明省略部分及び一の実施形態のみが有する要件は、それぞれ他の実施形態に適宜適用することができ、また、各実施形態における要件は、適宜、実施形態間で相互に置換可能である。   The description omitted in one embodiment and the requirements of only one embodiment can be applied to other embodiments as appropriate, and the requirements in each embodiment are appropriately interchanged between the embodiments.
