Absorptive article
An absorbent article using a surface sheet in which a side of the surface coming into contact with a skin is made of a non-woven fabric and a plastic film layer is stacked in a side of the back of the foregoing non-woven fabric, wherein the residence of a body fluid due to a capillary phenomenon or surface tension in an aperture wall part of the foregoing surface sheet is reduced and the body fluid is rapidly moved into a side of a hydrophilic second sheet or absorber as a lower layer, thereby not only keeping dryness and smoothness on the surface but also preventing turning back with a lapse of time. A surface sheet has a structure in which a side of the surface coming into contact with a skin is made of a non-woven fabric, a plastic film layer is stacked in a side of the back of the foregoing non-woven fabric, and a number of projecting parts and recessing parts are formed by embosses and a number of apertures are formed in the side of the surface coming into contact with a skin; and the foregoing apertures are formed in a proportion so as to have an aperture area of from 0.35 to 0.60 mm 2 per aperture and an aperture ratio of from 10 to 19%, and the aperture shape is an aperture shape not having an angledly bent corner.
1. An absorbent article, comprising:
a longitudinal axis defining a longitudinal direction of the absorbent article;
a liquid permeable surface sheet;
a back sheet joined with the liquid permeable surface sheet; and
an absorber mediated between said liquid permeable surface sheet and said back sheet,
said liquid permeable surface sheet having a structure in which a side of said surface coming into contact with a skin is made of a non-woven fabric, a plastic film layer is stacked in a side of the back of said non-woven fabric, and longitudinal rectangular embosses in a zigzag arrangement pattern are formed in a longitudinal direction of said absorbent article so that each of said embosses comprises a pair of longitudinally extending sides extending in said longitudinal direction of said absorbent article and a pair of sides respectively extending transversely relative to said longitudinally extending sides, said longitudinally extending sides being longer than said transversely extending sides, said embosses comprising a number of projecting parts and recessing parts, and said structure includes elliptical apertures, all of said elliptical apertures being arranged so that their major axes extend only in said longitudinal direction of said absorbent article and are formed in the side of the surface coming into contact with a skin, said apertures being in a zigzag arrangement pattern in a longitudinal direction of said absorbent article so that any given aperture and said given aperture's nearest adjacent aperture at a different longitude in said longitudinal direction of said absorbent article are laterally offset, and said apertures are positioned therealong the longitudinal direction of the absorbent article and relative to the embosses so that the recessing parts of the embosses do not entirely overlap the apertures and the apertures are either on top of or adjacent to projecting parts of one or more of the embosses,
said apertures being formed in a proportion so as to have an aperture area of from 0.35 to 0.60 mm 2 per aperture and an aperture ratio of from 10 to 19%, and the aperture shape is an aperture shape not having an angledly bent corner;
wherein each of the longitudinally extending sides of the rectangular embosses comprises a longitudinal length ranging from 2 to 5 mm., and each of the transversely extending sides of the rectangular embosses comprises a transversely extending length ranging from 0.2 to 2.0 mm.
