Publication number: 20040267224Abstract: A sanitary napkin having a main body, the main body comprising a fluid-permeable cover layer, a liquid-impervious barrier layer and an absorbent system intermediate the cover layer and the barrier layer. The main body comprises a front portion, a rear portion and a center portion intermediate the front portion and the rear portion. The front portion extends laterally to at least one outermost front distal point and the rear portion extends laterally outward to at least one outermost rear distal point. A side flap projects laterally outward from the absorbent system and laterally outward from a proximal edge and is adapted to be folded over a crotch portion a user's undergarment.

Publication number: 20040260263Abstract: A sanitary napkin that is provided with large rear flaps to effectively prevent liquid from leaking obliquely rearward. The rear flaps are disposed rearward of fold-back flaps to be wrapped around a crotch part of an undergarment. The rear flap is of a shape spreading rearwardly from a starting point. With a pressure from the thighs acting forward of the starting point, leakage preventing walls forward of the starting point can be maintained in a rising state during wear. On the other hand, the leakage preventing walls rearward of the starting point may possibly fall outward. However, even if the leakage preventing walls fall outward rearward of the starting point, they will never project out of the rear flaps. Accordingly, they hardly leave a stain on an undergarment.Type: ApplicationFiled: June 7, 2004Publication date: December 23, 2004Applicant: Uni-Charm CorporationInventors: Noritatsu Tamagawa, Masataka Kinoshita, Kazuya Nishitani, Toshiyuki Tanio

Publication number: 20040260262Abstract: A sanitary napkin has leakage preventing walls on a skin-side surface of a main body. The leakage preventing wall has a skin-contacting portion, of which an inner edge is fixed at an inner edge's front end and an outer edge is fixed at an outer edge's front end located forward of the inner edge's front end. Therefore, when the leakage preventing wall is in a rising position, the skin-contacting portion is inclined with the outer edge closer to the wearer's body than the inner edge. Accordingly, the skin-contacting portion can easily conform to the wearer's crotch on both sides of the vaginal opening.Type: ApplicationFiled: June 7, 2004Publication date: December 23, 2004Applicant: Uni-Charm CorporationInventors: Kazuya Nishitani, Toshiyuki Tanio, Masataka Kinoshita, Akane Sakai

Publication number: 20040243082Abstract: A sanitary napkin in which diffusing liquid hardly reaches a rear end edge is adapted to make a liquid absorbent layer less deformable in a rear region so that it can easily be kept in close contact with the wearer's buttocks. The sanitary napkin has an elongated main absorbent region surrounded by compressed grooves that are formed in a skin-side surface. Since a rear end of the main absorbent region is far away from a rear end edge of the napkin to provide a relatively large rear region, worries about rearward leakage may be relieved. Furthermore, since auxiliary longitudinal grooves are provided in the rear region, a liquid absorbent layer may hardly be twisted.Type: ApplicationFiled: May 7, 2004Publication date: December 2, 2004Applicant: Uni-Charm CorporationInventors: Masataka Kinoshita, Kazuya Nishitani, Toshiyuki Tanio, Akane Sakai

Publication number: 20040243087Abstract: Disclosed is a sanitary napkin which is effective in preventing liquid from leaking out obliquely rearward. The sanitary napkin has rear flaps rearward of fold-back flaps to be wrapped around a crotch part of an undergarment. The rear flap has a side edge substantially parallel to a longitudinal centerline. The rear flap is provided at its front portion with a rear pressure-sensitive adhesive layer. The rear pressure-sensitive adhesive layer is disposed forward of a rear end of a leakage preventing wall and a rear end of a main absorbent region. Since the rear flaps can be firmly fixed through the rear pressure-sensitive adhesive layers, the leakage preventing walls hardly move, so that the leakage preventing walls, as well as the rear flaps outside them, can effectively prevent obliquely rearward leakage.Type: ApplicationFiled: May 7, 2004Publication date: December 2, 2004Applicant: Uni-Charm CorporationInventors: Masataka Kinoshita, Kazuya Nishitani, Toshiyuki Tanio, Akane Sakai, Jun Kudo

Publication number: 20030195488Abstract: 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. During use, the garment attachment panels are fastened together beneath an undergarment crotch by hook and loop type fastener. The fastener and the garment attachment panels are dimensioned so that, when fastened, the garment attachment panels exert a pull on the raised side edges and control their deflection, thereby preventing them from folding in over the absorbent. The garment attachment panels confine the crotch portion of the undergarment under the absorbent so that the elasticized edges of the panty crotch are prevented from pulling up and onto the absorbent.Type: ApplicationFiled: April 4, 2003Publication date: October 16, 2003Applicant: Kimberly-Clark Worldwide, Inc.Inventors: Paul Theodore VanGompel, Julie Terese Brocker, Lori Sue Schutkoske

Patent number: 6613175Abstract: The present invention relates to a method of applying a hot melt adhesive to an absorbent article, such that the article has low autoadhesion, yet maintains excellent attachment properties during use in a consumer's undergarments. This is achieved by selecting the rheological properties of the adhesive and the mechanical properties of the substrate being coated. The adhesive is directly applied to a backsheet layer outer surface, wherein the adhesive has a viscosity of less than about 10,000 centipoise at a temperature of about 130 to about 177 degrees Celsius. The backsheet layer has a tensile strength of at least 5 Newtons per 25 millimeter width of material.Type: GrantFiled: March 30, 2000Date of Patent: September 2, 2003Assignee: McNeil-PPC Inc.Inventors: Michael Moscherosch, Joseph Michael Luizzi, Jr.

Patent number: 6602235Abstract: The present invention relates to a sanitary absorbent article such as a sanitary napkin that has the ability to protect the undergarment of the wearer from being soiled by menstrual liquid. The sanitary napkin has a main body with panels that originate from its longitudinal side edges. A distal end of each panel that is continuous with the respective longitudinal side edge is folded underneath and affixed to the barrier later of the main body to form a looping member and a freely extending flap. As a result the effective affixation point of each flap is located inwardly of the respective side edge of the main body.Type: GrantFiled: December 22, 1997Date of Patent: August 5, 2003Assignee: Johnson & Johnson, Inc.Inventors: Roger Boulanger, Pramod Mavinkurve, Tara Glasgow, Anthony Ng, Arnie Lingertat

Patent number: 6595977Abstract: The present invention relates to an absorbent article for managing bodily fluids, comprising a high coefficient of friction (“COF”) backsheet and at least one tape tab extending therefrom. The tape tab comprises a minimum amount of pressure sensitive adhesive sufficient to maintain the position of the article when a user's undergarments are away from her body. When the undergarments are near her body, the high COF backsheet acts as the predominant means for maintaining the position of the article due to normal forces exerted by the user's body and undergarments. When the user wants to remove the article from her undergarments, the tape tab provides additional advantages. The user may grasp the tape tab itself for removing the article as an alternative to grasping a portion of the soiled article. In addition the soiled article may be folded or rolled up, and then held in that configuration with the tape tab, for convenient and discreet disposal.Type: GrantFiled: April 20, 2000Date of Patent: July 22, 2003Assignee: McNeil-PPC, Inc.Inventors: Joseph Michael Luizzi, Jr., Miriam Motta
