Patent #: 7,163,530
Inventor(s): Haruko Toyoshima and Toshiaki Ichimata
Company: Kao Corporation
An absorbent article with a liquid permeable surface sheet has been issued a patent. A liquid impermeable leakage-prevention sheet and a liquid-retaining absorbent is formed in an oblong shape. The absorbent article is provided on longitudinal opposite sides with a pair of right and left elastic member-carrying three-dimensional guards, each of which has a skin-contacting surface portion formed by folding back a side on a free side toward an outer side of the absorbent article. The folded back side forms a folded portion and a first set of elastic members are fixed to a skin-contacting surface portion. A second set of elastic members are fixed to an approximately widthwise central portion of a raised portion. The raised portion is located between the skin-contacting surface portion and a base end of the three-dimensional guard. The raised portion is located near an inner side of the diaper. The elastic members in the second set in the raised portion are fixed between two sheet materials, which form the three-dimensional guard. The folded back portion is located between the skin-contacting surface portion and the raised portion. The skin-contacting surface portion is located more on a free end side than the folded back portion. The region of the guard widthwise ranges from the folded back portion to the free end and forms the skin-contacting surface portion.
