Publication number: 20020177833Abstract: An elongated, curved sanitary napkin having elasticized, raised side edges along the opposite sides of an absorbent. A garment attachment panel is secured to the underside of each raised side edge. A fixed portion of the garment attachment panel is bonded flat against each raised side edge so that a free portion of each of the garment attachment panels, extending from the fixed portion, is directed generally inward and downward.

Publication number: 20020035355Abstract: Disposable underpants 1 according to the invention has an improved sealability at the crotch of user by providing a fitting elastic member 55 and has an absorbent core 7 having an improved shape retention by providing a first nonwoven fabric 73 as an intermediate layer inside the absorbent core 7 and adhering it to the upper and lower layers thereof. Since the absorbent core needs not be heated, inexpensive disposable underpants can be produced. Further, according to an inventive production method, a step of adhering elastic members to an outer sheet 2 and a step of producing inner absorbent members 6 are separately performed, and no heating treatment is performed in the absorbent core production step. Accordingly, the disposable underpants can be produced at a remarkably higher speed.Type: ApplicationFiled: November 29, 2001Publication date: March 21, 2002Applicant: Toyo Keizai Kabushiki KaishaInventors: Kenichi Uchimoto, Iwao Matsuura

Patent number: 6358233Abstract: Absorbent articles, particularly sanitary napkins, having elastically extensible, laterally extending flaps are disclosed. The flaps are further provided with an adhesive for attaching them to a wearer's panty. At least a portion of the elastic extensibility has a vector component in the longitudinal direction. This longitudinally oriented elastic extensibility provides a contractive force which causes the absorbent article to assume an arcuate shape that more readily conforms to the wearer. Further, the extensibility allows the flaps to extend and contract with the edges of the leg openings of the wearer's panty so the flaps are more reliably adhered to the panty.Type: GrantFiled: March 13, 1996Date of Patent: March 19, 2002Assignee: The Procter & Gamble CompanyInventor: Jo Ann Lee Taylor
