Disposable pull-on diaper having interior elastic sheets and exterior non-elastic sheets

A disposable pull-on diaper having a longitudinal direction and a transverse direction being orthogonal to the longitudinal direction, including:

• a front waist region;
• a rear waist region;
• a crotch region;
• an absorbent chassis extending from the crotch region to the front and rear waist regions;
• lateral elastic regions formed in at least one of the front and rear waist regions so as to be elastically stretchable in the transverse direction from lateral edges of the absorbent chassis;
• and
• a central inelastic region defined between the lateral elastic regions and not being elastically stretchable, wherein:
• at least one of the front and rear waist regions includes an exterior sheet not being elastically stretchable in the transverse direction and a pair of interior sheets lying on an interior surface side of the exterior sheet and being elastically stretchable in the transverse direction;
• the absorbent chassis has an absorbent structure;
• the pair of interior sheets extends from lateral edges of at least one of the front and rear waist regions to lateral edges of the absorbent structure without extending across the absorbent structure;
• the interior sheets are attached under tension to the interior surface of the exterior sheet in the lateral elastic regions;
• and
• in the central inelastic region, the interior sheets are spaced apart from each other and are in an elastically relaxed state in vicinities of the respective lateral elastic regions.
