Inventor(s): Satoshi Mizutani, Koichi Yamaki and Yuki Noda
Company: Uni-Charm Corporation
An absorbent article has been patented. It includes an absorbent sheet body with a water permeable sheet facing a body side of a wearer and either a water permeable or water impermeable sheet facing a garment side. The absorbent body absorbs body fluid contained between the sheets. The article is applied to a pubic region and a body fluid inflow hole formed on the absorbent sheet body is depressed into a cylindrical shape with a bottom at the garment side and an opening at the body side with a size capable to fitting a pair of labia majoras from outside such that the pair of labia majoras pass through the opening. The cylindrical shape of the body fluid inflow hole has a hollow part. A side wall portion of the body fluid inflow hole protrudes downward toward the garment side to form a flange. The side wall of the body fluid inflow hole includes an elastically restoring material and comprises an adhesive portion surrounding a periphery of the opening of the body fluid inflow hole on a body side face. Folded pleats are located around the adhesion portion and extend along an entire longitudinal length of the article.
