UNDERPANTS-TYPE DISPOSABLE DIAPER Russian patent published in 2019 - IPC A61F13/15 

FIELD: hygiene.

SUBSTANCE: present invention is intended to provide advantages associated with formation of leg assemblies, which are provided with film not permeable for liquids. Said problem is solved by making leg assemblies (60) having: inner layer (61) of non-woven material, forming a surface inner in width direction; outer layer (62) of non-woven material, forming a surface outer in the width direction; elastically stretchable assembly materials (63), which are provided along the forward-backward direction between the inner nonwoven material layer (61) and the nonwoven material outer layer (62) in at least the front end portions in parts intermediate in the forward-back direction, and film (64), not permeable for liquids, which is located between inner layer of nonwoven material and outer layer (62) of non-woven material in area from base end to place closer to side of front end than base end, and are made with such configuration that legs assemblies (60) having film (64), not permeable for liquids, and located closer to base end side than front end parts, form sections (65) with absence of non-woven material, on which inner layer (61) of non-woven material is absent and film (64), not permeable for liquids, is exposed.

EFFECT: enabling reduction of used amount of non-woven material with simultaneous suppression of texture deterioration and other advantages.
