Description
(側部バリヤーシート)
図3及び図4にも示されるように、物品内面の両側部(図示形態ではトップシート2の側縁部表面からその側方に延在する液不透過性シート1の表面)には、側部バリヤーシート4の幅方向外側の付根部分4xが前後方向全体にわたり貼り付けられている。側部バリヤーシート4は、各種不織布(スパンボンド不織布が好適である)の他、液不透過性シートに用いられるものと同様のプラスチックフィルム、又はこれらの積層シートを用いることができるが、肌への感触性の点で、撥水処理を施した不織布が好適である。側部バリヤーシート4の幅方向中央側の本体部分4cは、前後方向両端部では物品内面(図示形態ではトップシート2表面)にホットメルト接着剤等の手段により固着されているが、これらの間の中間部は非固定の自由部分となっており、この自由部分の先端部(展開状態における幅方向中央側の端部)には、細長状弾性部材4Gが前後方向に沿って伸長した状態でホットメルト接着剤等により固定されている。この細長状弾性部材4Gは図示例では所定の間隔を空けて複数本設けられているが、一本でも良い。細長状弾性部材4G(他の細長状弾性部材も同様)としては、糸状、紐状、帯状等に形成された天然ゴム又は合成ゴム、具体的にはスチレン系ゴム、オレフィン系ゴム、ウレタン系ゴム、エステル系ゴム、ポリウレタン、ポリエチレン、ポリスチレン、スチレンブタジエン、シリコーン、ポリエステル等、通常使用される素材を用いることができる。この自由部分は、細長状弾性部材4Gの収縮力が作用する結果、図4に示されるように、物品内面(図示形態ではトップシート2表面)に対して起き上がる側部バリヤーを構成する。この起き上がり部分の起点4bは側部バリヤーシート4における幅方向外側の固定部分4xと内側の部分4cとの境に位置する。なお、図1中の右斜め上がりの斜線部分は側部バリヤーシート4の固着部分を示している。
(side barrier sheet)
As shown in FIGS. 3 and 4, both sides of the inner surface of the article (in the illustrated embodiment, the surface of the liquid-impermeable sheet 1 extending laterally from the side edge surface of the top sheet 2) are provided with side surfaces. A root portion 4x on the outside in the width direction of the partial barrier sheet 4 is attached over the entire front-to-rear direction. The side barrier sheet 4 can be made of various nonwoven fabrics (preferably spunbonded nonwoven fabric), plastic films similar to those used for liquid-impermeable sheets, or laminated sheets thereof. A nonwoven fabric treated with a water-repellent treatment is preferable from the point of view of the tactile sensation. The main body portion 4c on the center side in the width direction of the side barrier sheet 4 is fixed to the inner surface of the article (the surface of the top sheet 2 in the illustrated embodiment) at both ends in the front-rear direction by means of a hot-melt adhesive or the like. The intermediate portion of the is a non-fixed free portion, and at the tip of this free portion (the end on the center side in the width direction in the unfolded state), an elongated elastic member 4G is stretched along the front-rear direction. It is fixed with a hot-melt adhesive or the like. Although a plurality of elongated elastic members 4G are provided at predetermined intervals in the illustrated example, one may be provided. The elongated elastic member 4G (the same applies to other elongated elastic members) is made of natural rubber or synthetic rubber formed in the shape of a thread, string, belt, etc., specifically styrene rubber, olefin rubber, or urethane rubber. , ester-based rubber, polyurethane, polyethylene, polystyrene, styrene-butadiene, silicone , polyester, and the like can be used. This free portion constitutes a side barrier which rises against the inner surface of the article (the surface of the topsheet 2 in the illustrated embodiment), as shown in FIG. The starting point 4b of this raised portion is located at the boundary between the widthwise outer fixed portion 4x and the inner portion 4c of the side barrier sheet 4. As shown in FIG. In FIG. 1 , the obliquely shaded portion slanted upward to the right indicates the fixed portion of the side barrier sheet 4 .
