Patent ID: 10842689

Abstract:
A stretchable structure of an absorbent article includes a stretchable region and a non-stretchable region. A laminate of a first sheet layer, second sheet layer, and elastic film between the first and second sheet layers extends over the stretchable and non-stretchable regions. The first and second sheet layers are bonded to each other at a large number of dot-like joints via through holes formed in the elastic film stretched along the surfaces of the first and second sheet layers in a stretchable direction. The dot-like joints are arrayed at intervals in the stretchable direction and a direction perpendicular to the stretchable direction. An end of the stretchable region adjacent to the non-stretchable region is a buffer stretchable section. The area rate of dot-like joints in the buffer stretchable section is larger than the area rate of dot-like joints in the main section not including the buffer stretchable section.
