Abstract

A brief-type diaper in which a brief-type diaper precursor 81) is formed such that a pre-leg opening part (6) straddles a pre-girth part (4) at a laterally symmetric twin chevron pre-crotch part (5) extending entirely from a lower fringe at the substantially rectangular pre-girth part (4). An absorber (7) is disposed on the upper surface of the panty type diaper precursor (1) and folded laterally along a line-symmetric axis Y-Y. The pre-girth part (4) and the pre-crotch part (5) are thereby overlapped and then the side fringe parts (4a) and the lower fringe parts (5a) are bonded respectively thus obtaining a panty diaper having no joint at the left and right bodies in the girth area.

Description

technical field [0001] The present invention relates to a pant-type diaper, and more particularly, to a pant-type diaper material body that is formed by laminating and folding an absorber capable of absorbing bodily fluids in the central region of the pant-type diaper material body, joining the side edge portions of the pant-type diaper material body and forming it in the form of panties. diaper. Background technique [0002] Such diapers such as Figure 12 (See Japanese Patent Application Laid-Open No. 6-296638). The figure shows the sheets of the diaper unfolded. In the sheet layer a, the chevron-shaped cutout b is formed on the left and right side edges, and the absorber e is provided across the front body c and the back body d. Then, the sheet layer a is folded up and down, and the side edge portions f thereof are joined to form waist openings and leg openings. [0003] However, in such a diaper, in order to join the side edges f of the front body c and the back body ...
