Foldable disposable diaper

摘要

Thin thickness parts are formed in the absorption core present in the front waist region and the back waist region of a diaper. The thickness of the diaper at the thin thickness part is preferably 1/2-fold or less the thickness of the absorption core at the thick thickness part in the crotch region. When the diaper is folded along a line parallel to the longitudinal direction of the diaper, the front waist region and the back waist region are folded at the thin thickness parts to overlay the thin thickness parts together. Thus, the thickness of the front waist region and the back waist region when folded along the folding line is the same as the thickness of the thick thickness part. Therefore, the thickness of the folded diaper can be made thin, with no reduction of the thickness of the absorption core in the crotch region where urine is mainly absorbed. <IMAGE>
