- the body of a wearer who wears a pant-type absorbent article in particular the body of a baby, has a complex shape in which it has a bulge from the waist to the buttocks, while it curves from the abdomen to the lower abdomen.
- the pants-type absorbent articles currently manufactured industrially generally have a substantially cylindrical shape, when trying to fit the wearer's body in the wearing state, the above-mentioned buttocks are distorted. On the contrary, there is a possibility that the fit may be deteriorated or the wearing feeling may be deteriorated. Therefore, an object of the present invention is to provide a pants-type absorbent article in which such a disadvantage is eliminated.
- FIGS. 1 and 2 show a pants-type disposable diaper 1 which is an embodiment of the pants-type absorbent article of the present invention.
