Problems solved by technology

A problem with earlier designs of sanitary napkins with flaps was that when the flaps were pulled into position, there was a tendency for liquid to seep along the surface of the flaps, contaminating the wearer's garments, because There is no effective leak-proof layer on the side of the towel
During the manufacturing process, separate material sheets are required to manufacture the positioning flap and the central absorbent body, resulting in a more expensive manufacturing process
Also, as in U.S. Patent No. 5,387,210, there is a potential danger of the lateral barrier pressing against the user's skin, thereby rendering it ineffective
