Patent number: 6283952Abstract: The invention provides an improved tampon, particularly suited for use as a digital tampon, having a portion of fibers at a withdrawal end of the tampon displaced towards an insertion end, causing a fiber density in the vicinity of the withdrawal end to be lower than an average fiber density of the tampon. The tampon also includes an indentation in the withdrawal end. In combination, the lower fiber density of the withdrawal end and the indentation in the withdrawal end cause the withdrawal end to be soft and readily flareable. When the tampon is provided with an overwrap the indentation also allows excess overwrap at the withdrawal end to be tucked into the tampon, improving the aesthetic qualities of the tampon and facilitating digital insertion.Type: GrantFiled: May 5, 1997Date of Patent: September 4, 2001Assignee: Tambrands, Inc.Inventors: William M. Child, Warren Tarr

Patent number: 6270470Abstract: A method for providing side-to-side coverage of a tampon within a female user's vaginal cavity is provided. By use of a tampon applicator designed to provide directional expulsion and suitable tampons for use in the tampon applicator, a female user may achieve side-to-side coverage of a tampon within her vaginal cavity. Such directional expulsion causes a suitable tampon to expand against the sides and/or walls of a female user's vaginal cavity.Type: GrantFiled: June 29, 1999Date of Patent: August 7, 2001Assignee: The Procter & Gamble CompanyInventors: Kimberly Ann Buck, Lisa Ann MacKay, William Patton Peace, Chrissie Melinda Smits, Richard Tweddell, III, Eric Patton Weinberger

Patent number: 6270486Abstract: An absorbent interlabial device worn by female wearers for catamenial purposes, incontinence protection, or both, is disclosed. The absorbent interlabial device of the present invention includes a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent core positioned between the two. The length of the device is between about 60 mm and about 130 mm. The width is between about 25 mm and 50 mm. The device has an axis of preferred bending along its longitudinal centerline. When folded along the axis and inserted into the wearer's interlabial space, the topsheet maintains contact with the walls of the wearer's labia. A method of using a system of feminine hygiene products is also disclosed. The system includes the use of an absorbent interlabial device in combination with a sanitary napkin. The absorbent interlabial device of the present invention may also be used in combination with an absorbent tampon.Type: GrantFiled: May 1, 1998Date of Patent: August 7, 2001Assignee: The Procter & Gamble CompanyInventors: Pamela Jean Brown, Thomas Ward Osborn, III

Publication number: 20010011169Abstract: This invention relates to absorbent tampons. More particularly, the invention relates to an improved absorbent tampon having improved leakage performance. Tampons, having a primary absorbent member which is constructed from an absorbent material compressed to a self-sustaining form and a mass of secondary absorbent material are disclosed. The mass of secondary absorbent material is preferably located generally proximate the withdrawal end of the primary absorbent member, and is preferably substantially non-compress, and preferably of a smaller diameter than the primary absorbent member. The mass of secondary absorbent material may be a multiple pieces or one piece. The secondary absorbent material may be attached to the primary absorbent member, the withdrawal cord, or both, or may be integral with one or both of these members. The withdrawal cord of the tampon may have absorbent and non-absorbent zones, especially when the mass of secondary absorbent material is attached to the withdrawal cord.Type: ApplicationFiled: April 2, 2001Publication date: August 2, 2001Applicant: The Procter & Gamble CompanyInventors: Fiona M.

Patent number: 6254566Abstract: A suitable tampon with a tampon applicator for expelling the tampon to provide side-to-side coverage and inserting the tampon into a body cavity is provided. The tampon applicator has a tampon holder tube having interior and exterior surfaces, a longitudinal axis, a hollow portion and an expulsion end dimensioned for insertion into the body cavity. The tampon holder tube has a feature for separating and spreading a tampon apart during expulsion of the tampon. A plunger may also be telescopically and slidably mounted in the tampon holder tube distal to the expulsion end and adapted to directionally expel the tampon from the tampon holder tube when a user expels the tampon from the tampon holder tube.Type: GrantFiled: June 18, 1999Date of Patent: July 3, 2001Assignee: The Procter & Gamble CompanyInventors: Kimberly Ann Buck, Lisa Ann MacKay, William Patton Peace, Chrissie Melinda Smits, Richard Tweddell, III, Eric Patton Weinberger

Patent number: 6254584Abstract: An interlabial absorbent structure is disclosed. The interlabial absorbent structure comprises a pair of absorbent panels that are sufficiently flexible such that the panels can, at least partially, conform to the walls of a wearer's interlabial space. The panels are joined by an isthmus which is positioned farthest into a wearer's interlabial space when the interlabial absorbent product is worn. Alternative embodiments of the isthmus are also described which direct bodily fluids that are deposited thereon along the longitudinal length of the interlabial absorbent structure.Type: GrantFiled: January 3, 1997Date of Patent: July 3, 2001Assignee: The Procter & Gamble CompanyInventors: Thomas Ward Osborn, III, Katherine Louise Mayer, Letha Margory Hines, Edward J.
