Patent ID: 7976523

Claim:
An absorbent product, comprising: a surface sheet which is liquid-impermeable; a back sheet which is liquid-impermeable positioned under the surface sheet; and an absorber including super absorbent polymer, the absorber being positioned between a lower side of the surface sheet and the back sheet, wherein the surface sheet fully covers in a lateral direction, and partially or fully covers in a longitudinal direction, an upper surface of the absorber, the longitudinal direction being a direction from front to back of a wearer's body when the absorbent product is worn and perpendicular to the lateral direction, the back sheet fully covers a lower surface of the absorber in the longitudinal direction and the lateral direction, and includes a left wall and a right wall, the left wall and the right wall extending along a left side and a right side of the absorber respectively, and exceeding the surface sheet in a lamination direction in which the absorber and the surface sheet are laminated on the back sheet, a set of flow passages formed in the longitudinal direction beginning an upper side of the surface sheet where a discharged liquid is supplied from the wearer's body, each flow passage exceeding each lateral end of the surface sheet and extending along a space between the left and right walls of the back sheet and the left and right sides of the absorber respectively, and each flow passage is provided such that at least a part of the discharged liquid flows off from the surface sheet into at least one of the flow passages, toward the back sheet and moves between the back sheet and the absorber.
