Abstract:
(EN) [Problem] To prevent excessive closure of joining holes and reduction in breathability. [Solution] The present invention has an elastic sheet stretchable structure in which a first sheet layer and a second sheet layer are joined via joining holes 31 extending through an elastic film 30 at a large number of joining parts spaced apart from one another. A joining part group 40, 40 in a stretchable region satisfies a relationship that the joining part group 40, 40 intersects lines ED in the stretch direction at any position in the perpendicular direction LD or a relationship that in a width region extending 0.5 mm or less in the perpendicular direction between the lines ED in the stretch direction, the joining part group 40, 40 does not intersect the lines ED in the stretch direction, and also satisfies a relationship that in a predetermined perpendicular-direction width region H extending in the perpendicular direction between oblique lines q of an oblique line group which intersect the lines ED in the stretch direction at an angle within an angle range γ of 45 degrees or less, the joining part group 40 40 does not intersect the oblique lines.
(FR) Le problème décrit par la présente invention est d'empêcher une fermeture excessive de trous de jonction et une réduction de la respirabilité. La solution selon l'invention porte sur une structure étirable de feuille élastique, dans laquelle une première couche de feuille et une seconde couche de feuille sont jointes par l'intermédiaire de trous de jonction (31) s'étendant à travers un film élastique (30) au niveau d'un grand nombre de parties de jonction espacées les unes des autres. Un groupe de parties de jonction (40, 40) dans une région étirable satisfait une relation telle que le groupe de parties de jonction (40, 40) croise des lignes (ED) dans la direction d'étirement à n'importe quelle position dans la direction perpendiculaire (LD), ou une relation telle que, dans une région de largeur s'étendant à 0,5 mm ou moins dans la direction perpendiculaire entre les lignes (ED) dans la direction d'étirement, le groupe de parties de jonction (40, 40) ne croise pas les lignes (ED) dans la direction d'étirement, et satisfait également une relation telle que, dans une région de largeur de direction perpendiculaire prédéterminée (H) s'étendant dans la direction perpendiculaire entre des lignes obliques (q) d'un groupe de lignes obliques qui croisent les lignes (ED) dans la direction d'étirement à un angle dans une plage d'angles γ de 45 degrés ou moins, le groupe de parties de jonction (40, 40) ne croise pas les lignes obliques.
(JA) 【課題】接合孔が過度に閉じ通気性が低下することを防止する。 【解決手段】 第1シート層及び第2シート層が、間隔を空けて配列された多数のシート接合部で、弾性フィルム30を貫通する接合孔31を通じて接合された、弾性シート伸縮構造を備えており、前記伸縮領域の接合部群40,40が、前記直交方向LDの各位置で前記伸縮方向線EDと交差する関係にある、あるいは前記伸縮方向線EDの前記直交方向LDの0.5mm以下の離間幅においては、前記伸縮方向線EDと交差しない関係にあり、かつ、前記伸縮方向線EDと45度以下の角度範囲γ内で交差する斜線qの前記直交方向の斜線群における、所定の前記直交方向離間幅Hにおいては、前記接合部群40,40が斜線と交差しない関係にある。
