Abstract:
(EN) [Problem] To minimize the occurrence of welding defects when sheet joining portions having different shapes are used. [Solution] The abovementioned problem is solved by an elastic member characterized by having an elastic sheet elastic structure 20X in which an elastic sheet 30 is interposed between a first sheet layer 20A made from a nonwoven fabric and a second sheet layer 20B made from a nonwoven fabric, the first sheet layer 20A and the second sheet layer 20B are welded via bonding holes which pass through the elastic sheet 30 at a large number of sheet bonding portions 40 arranged with an interval therebetween, and the region having the elastic sheet elastic structure 20X has sheet bonding portions 40 having different shapes, and all sheet bonding portions 40 in the region having the elastic sheet elastic structure 20X have a bonding reference diameter φ of at least 0.2 mm, the maximum value for the bonding reference diameter φ is a multiple of 1 to 3 times the minimum value, and the circumference is a multiple of 1 to 15 times the length of the perimeter of a circle having the bonding reference diameter φ as the diameter.
(FR) Le problème décrit par la présente invention est de réduire au minimum l'apparition de défauts de soudage lorsque des parties de jonction de feuilles ayant des formes différentes sont utilisées. La solution selon l'invention porte sur un élément élastique caractérisé en ce qu'il présente une structure élastique de feuilles élastiques (20X) dans laquelle une feuille élastique (30) est interposée entre une première couche de feuille (20A) constituée d'un non-tissé et une seconde couche de feuille (20B) constituée d'un non-tissé, la première couche de feuille (20A) et la seconde couche de feuille (20B) étant soudées par l'intermédiaire de trous de liaison qui traversent la feuille élastique (30) au niveau d'un grand nombre de parties de liaison de feuilles (40) agencées à intervalles ; et en ce que la région comprenant la structure élastique de feuille élastique (20X) comporte des parties de liaison de feuilles (40) ayant des formes différentes, et toutes les parties de liaison de feuilles (40) dans la région comprenant la structure élastique de feuille élastique (20X) présentent un diamètre de référence de liaison φ d'au moins 0,2 mm, la valeur maximale du diamètre de référence de liaison φ étant un multiple de 1 à 3 fois la valeur minimale, et la circonférence étant un multiple de 1 à 15 fois la longueur du périmètre d'un cercle ayant le diamètre de référence de liaison φ comme diamètre.
(JA) 【課題】形状の異なるシート接合部を有する場合における溶着不良を起こりにくくする。 【解決手段】上記課題は、不織布からなる第1シート層20A及び不織布からなる第2シート層20Bの間に弾性シート30が介在され、第1シート層20A及び第2シート層20Bが、間隔を空けて配列された多数のシート接合部40で、弾性シート30を貫通する接合孔31を通じて溶着された、弾性シート伸縮構造20Xを有し、弾性シート伸縮構造20Xを有する領域は、弾性シート伸縮構造20Xを有する領域は、形状が異なるシート接合部40を有しており、弾性シート伸縮構造20Xを有する領域におけるすべてのシート接合部40は、接合基準径φが0.2mm以上であり、接合基準径φの最大値が最小値の1~3倍であり、かつ周長が接合基準径φを直径とする円の円周の長さの1~15倍である、ことを特徴とする伸縮部材により解決される。
