At least one of the respective front and back parts (1, 2) has at least one elastically stretchable region (29, 30). The crotch-part (3) is essentially non-stretchable in relation to the stretchable region (29, 30). At least one of respective end-parts (17, 18) of the absorbent pad (14) is disposed within one of the elastically stretchable regions (29, 30), while the center-part (19) of the absorbent pad is disposed within the relatively non-stretchable crotch-part (3) of the pants.

Abstract: A method of securing an elastic band between two material layers which are at least partially defined by meltable material includes forming perforations in the elastic band, placing the elastic band between two material layers, and bonding the material layers to one another through the perforations by heat fusion, wherein the perforations in the elastic band are formed at the same time as the material layers are fused together (i.e., the formation of the perforations in the elastic band is directly followed by bonding together, through the perforations, portions of the material layers). An elastic band secured between two material layers for inclusion in articles of one-time use includes the use of material layers that are at least partially defined by meltable material and an elastic band having perforations formed therein. The material layers are positioned on opposite sides of the elastic band and are joined together by heat fusion in a punctiform and/or linear bonding pattern.
