Patent #: 7,329,243
Inventor(s): Satoshi Mizutani, Wataru Yoshimasa and Yuki Noda
Company: Uni-Charm Corporation
An inter-labial pad has been granted a patent. The pad comprises an absorbent body that absorbs a body fluid. A surface side sheet covers one surface of the absorbent body and is in contact with the labia in an inserted state. A back face sheet covers an opposite surface of the absorbent body. A top portion is formed by folding the inter-labial pad along a longitudinal centerline of the inter-labial pad, such that the resulting two folded halves of the back face sheet oppose each other. The top portion is in contact with the labia in the inserted state. A side edge portion is formed by laminating the surface side sheet and the back face side sheet that cover the absorbent body. A backward end of the top portion includes paired side portions of the back face sheet and are formed by folding the inter-labial pad along the longitudinal center line. The side portions at the top of the backward end are adhered and formed into a sharp shape for insertion between the labia. A forward end of the folded side portions is not adhered to each other and releasable along the longitudinal centerline. The width of the forward end of the side edge portion is wider than the width of the backward end of the top portion.
