Publication number: 20230200459Abstract: A wearable article includes a front and back elastic belts, a crotch region, a waist opening, and leg openings. Each elastic belt is a laminate having an inner sheet, an outer sheet, and an elastic member. Elastic adhesive bonding continuously bonds the elastic member for at least about 10 mm in the direction of stretch adjacent the side edges of the belts. A discrete patterned adhesive bonding is applied to at least one of the inner and outer sheets to intermittently bond the inner and outer sheets. The discrete patterned adhesive bonding extends substantially along the transverse direction between the elastic adhesive bonding, and substantially along the longitudinal direction between the distal and proximal edges of the elastic belts. The same adhesive agent provides the elastic adhesive and discrete patterned adhesive bonding. Heat bonds form side seams, and the remainder of the laminate is free of heat bonds.Type: ApplicationFiled: February 17, 2023Publication date: June 29, 2023Inventors: Shiqiao LI, Ruizhi PEI, Kaoru ISHIHARA, Koichi MORIMOTO, Xuechun WANG, Ling TONG, John Andrew STRASEMEIER, Vanessa Marie MELENDEZ, Monica Renee TOURNOUX
