Abstract
Abstract A disposable garment of pants type, such as a disposable diaper of pants type, is constructed by attaching respective leg-hole surrounding flaps and waist-hole surrounding flaps to respective opposite side edges extending longitudinally of a basic assembly for the garment which comprises at least a topsheet and a backsheet. The leg-hole surrounding flaps and the waist-hole surrounding flaps respectively cooperate to form a pair of leg-holes. A pair of shoulder straps can be easily prepared by making a slit which extends longitudinally of the garment on each waist-hole surrounding flap. A disposable garment of the present invention is featured in its simple construction and easy production.
