Abstract
(EN)
[Problem] To prevent absorbed liquid from being conspicuous in appearance, without the feel being impaired. [Solution] A plurality of embossed portions (10, 10 ...) recessed to a non-skin side are disposed spaced apart on a skin side surface of a liquid-permeable surface sheet (3). The embossed portions (10) have as an original shape (11) a rectangular shape of which the number of sides is four, and are formed in a planar shape having a concave outline (14) comprising curves which pass through corner portions (12) of the original shape (11) and which are obtained by causing sides (13) of the original shape (11) to bulge toward the center thereof. Since liquid consolidating regions (15) formed along the periphery of the embossed portions (10) are separated at a central portion, the liquid consolidating region (15) is inconspicuous in appearance. Further, since peripheral length is gained by means of the concave shaped outline (14) while the compressed surface area is reduced, body fluids are dispersed and the color of the body fluids is less liable to be conspicuous, without the feel being impaired.

Le problème décrit par la présente invention est d'empêcher que le liquide absorbé soit visible en apparence, sans que la sensation ne soit altérée. La solution selon l’invention porte sur une pluralité de parties gaufrées (10, 10 ...) en retrait vers un côté opposé à la peau disposées à distance sur une surface côté peau d'une feuille de surface perméable aux liquides (3). Les parties gaufrées (10) ont dans une forme d'origine (11) une forme rectangulaire dont le nombre de côtés est quatre, et sont formées dans une forme plane ayant un contour concave (14) comprenant des courbes qui passent à travers des parties de coin (12) de la forme d'origine (11) et qui sont obtenues en amenant des côtés (13) de la forme d'origine (11) à se bomber vers le centre de celle-ci. Comme des régions de consolidation de liquide (15) formées le long de la périphérie des parties gaufrées (10) sont séparées au niveau d'une partie centrale, la région de consolidation de liquide (15) est discrète en apparence. En outre, étant donné que la longueur périphérique est obtenue au moyen du contour de forme concave (14) tandis que la zone de surface comprimée est réduite, les fluides corporels sont dispersés et la couleur des fluides corporels est moins susceptible d'être visible, sans que la sensation ne soit altérée.

【課題】肌触りを悪化させることなく、吸収された体液が外観上目立たないようにする。【解決手段】透液性表面シート(3)の肌側面に、非肌側に窪むエンボス部(10、10…)が間隔をあけて複数配置されている。前記エンボス部(10)は、4つの辺の数を有する四角形を原形図形(11)とし、前記原形図形(11)の各角部(12)を通るとともに、前記原形図形(11)の各辺(13)を中心側に膨出させた曲線からなる凹形状の外形線(14)を有する平面形状で形成されている。エンボス部(10)の周囲に沿って形成された液集約領域(15)が中央部で離隔するため、液集約領域(15)が外観上目立たなくなる。また、圧搾面積を小さくしながら、凹形状の外形線(14)によって周長がかせげるので、肌触りを悪化させることなく、体液が分散して体液の色が目立ちにくくなる。
