Abstract:
A disposable undergarment comprising:a skin-contactable surface; a non skin-contactable surface opposed to the skin-contactable surface; a liquid-impervious base sheet; longitudinally opposed end portions extending in a transverse direction and transversely opposite side edge portions extending in a longitudinal direction; a liquid-absorbent panel positioned between said skin-contactable surface and said non skin-contacting surface; a pair of skin-contactable sheets which are stretchable in said longitudinal direction and substantially liquid-impervious, said skin-contactable sheets having fixed surface areas and free surface areas between said fixed surface areas, said pair of skin-contactable sheets being attached under extension in said longitudinal direction at said fixed surface areas to said skin-contactable surface with said pair of skin-contactable sheets spaced apart from and opposed to each other in said transverse direction and extending along said transversely opposite side edge portions so that said free surface areas are spaced apart upward from said liquid-absorbent panel as said undergarment curves in said longitudinal direction with its skin-contactable surface inside; and a pair of substantially liquid-impervious leak-barrier cuffs spaced apart from and opposed to each other in said transverse direction and extending along said transversely opposite side edge portions of said undergarment, said pair of leak-barrier cuffs being disposed between said base sheet and said skin-contactable sheets and attached in said longitudinal direction to said skin-contactable surface, said leak-barrier cuffs having fixed side edge portions fixed to said transversely opposite side edge portions of said undergarment and extending in said longitudinal direction, free side edge portions being stretchable in said longitudinal direction and normally biased to rise on said skin-contactable surface and longitudinally opposite fixed end portions collapsed onto said skin-contactable surface and fixed to said longitudinally opposite end portions in a collapsed state so that said free surface areas of said skin-contactable sheets are kept spaced upward from said free side edge portions of said leak-barrier cuffs.
