  • Patent number: 6423043
    Abstract: Absorbent article such as a sanitary napkin, a panty liner or an incontinence pad, includes a first absorbent part and a second part, which each have a substantially elongate shape with a longitudinal direction and a transverse direction, and two end portions. The two parts are mutually joined solely at their end portions. The second part is curved in the longitudinal direction and has high resistance to flexure along flexure lines parallel to the article's transverse direction both in a wet and dry condition, while the first part in a non-influenced condition has a lesser extension in a longitudinal direction than the second part and comprises at least one elastically extensible region in the longitudinal direction.

  • Publication number: 20020095132
    Abstract: Absorbent articles having improved sustained fit on the body, improved appearance through the period of use, and improved comfort for the wearer. The absorbent article has a containment assembly, a waist feature and a diagonal support member feature disposed so as to lie in the diagonal support zone of the wearer's body when the article is worn. The diagonal support member is designed to support the article from the small of the back, over the hip, and to the lower abdomen. The diagonal support member is distinct from the waist feature, which is designed to provide only enough circumferential tension to hold itself in position on the body. The absorbent article has a garment-like high-waisted appearance, gentle tension around the waist to avoid discomfort and/or pressure marking, good leakage protection, good sustained fit, and easy application and removal.

  • Publication number: 20020095130
    Abstract: A self-adhesive garment closure for a garment includes a pair of opposed cooperating fastener elements, each having an exposed layer of self-adhesive material exhibiting strong adhesion to itself while remaining relatively tack-free to other materials. At least one of the fastener elements has a layer of foam material beneath the self-adhesive material, such as for increased bending stiffness. In some cases, such as for pull-up diapers, the self-adhesive closure is non-releasable once secured. Some closures also have cooperating hook-and-loop elements.

  • Patent number: 6387083
    Abstract: A pull-on disposable diaper has front and rear waist regions placed upon each other along their respective side edges and bonded together at outer bonding zone intermittently arranged along these side edges. A plurality of sheet materials forming the respective side edges of the front and rear waist regions are bonded together along an inner bonding zones vertically extending inside each of the outer bonding zone. The inner bonding zone prevents transversely opposite side edges of the diaper from being torn in a circumferential direction thereof, when the transversely opposite side edges of the diaper are torn off vertically of the diaper.

  • Publication number: 20010053903
    Abstract: A disposable diaper has a pair of rear wings and the wings partially extend outward in a circumferential direction to form fastener sections. The wings are formed on inner surfaces thereof with a plurality of fine depressions. The number of these depressions per unit area on the inner surfaces of the respective rear wings is less in regions adapted to be engaged with the male members of the respective fastener sections as these fastener sections are folded back onto the inner surfaces of the respective rear wings than in the remaining region.

  • Patent number: 6306123
    Abstract: An absorbent article, such as a sanitary napkin, is disclosed which has a stabilizing element having a length and a width sufficient to conform to the longitudinal dimensions of a wearer's labia majora. The stabilizing element provides the article with enhanced resistance to bunching and inward collapse due to lateral compressive forces imparted by a user's thighs. The stabilizing element is resistant to wet collapse so that a central absorbent portion of the article maintains contact with the perineal area of the user.

  • Patent number: 6307120
    Abstract: An adult brief garment for use in controlling incontinence is provided. The brief has a chassis which includes a front portion, back portion and an interposed crotch portion. The chassis consists of a fluid-impervious, cloth-like laminate along the central region of the chassis and hydrophobic, cloth-like, nonwoven side panels at each side of the central region. An liquid absorbent core is positioned over the central region. Plural fastening tapes are applied to the side panels at the back portion of the chassis. The front portion of the chassis includes soft, flexible landing zones for releasable receipt of the tapes to hold the brief in place. Each landing zone takes up a substantial portion of its associated side panel and contiguous portions of the central region of the chassis and each includes a myriad of small (e.g., micro-sized) apertures or holes therein for breathability, e.g., to allow moisture vapor to pass therethrough.

  • Patent number: 6300538
    Abstract: An absorbent article (10) such as a sanitary napkin, having an elongate absorbent core (12) delimited by an upper surface (14) and a lower surface (16), a pair of opposed longitudinal edge portions (18, 20) terminating in longitudinal edges (22, 24), and a pair of opposed transverse edges (26, 28). The core has a first end portion (30), a second end portion (32) and a mid portion (34) located between the end portions. The article further includes a liquid permeable topsheet (36) extending over the upper surface (14) and a liquid impermeable sheet (38) covering the longitudinal edge portions (18, 20) of the absorbent core (12). A strip of generally hydrophobic resilient material (40) is placed between the liquid impermeable sheet (38) and the absorbent core (12) along each longitudinal edge portion (18, 20) of the absorbent core in at least the mid portion (34) to thereby increase the flexure resistance of the article.

  • Patent number: 6284943
    Abstract: A disposable absorbent article for wearing in an undergarment, such as a sanitary napkin, pantiliner, or incontinence pad is described. The absorbent article includes a topsheet, a backsheet, an absorbent core, and a stiffening feature. The stiffening feature places the absorbent article in an initially stiffened condition during placement of the article in an undergarment. After the article is subjected to the forces exerted by the body of the wearer, the stiffening feature no longer provides an increased initial stiffness and the article becomes more flexible.

  • Patent number: 6218593
    Abstract: An absorbent article includes a liquid permeable topsheet, a liquid impermeable back sheet, and an absorbent member interposed between the topsheet and the back sheet. While worn, the absorbent article forms a front waist body portion located at the front waist of a wearer and a rear waist body portion located at the rear waist of a wearer. The rear waist body portion has at each side thereof a fastening member for fastening the absorbent article, wherein the back sheet is made up of laminated sheeting composed of a finely porous resin film and nonwoven fabric. The fastening member is formed of a male sheet member of a mechanical fastener and designed to be brought into direct contact with the surface of the nonwoven fabric constituting the back sheet. The above-mentioned absorbent article has a good fit on a wearer, exhibits excellent leakproofness and breathability while worn, and has an excellent texture.

  • Patent number: 6168584
    Abstract: A spacer for use in a disposable absorbent article. The spacer is symmetric about a longitudinal axis and has two transversely oriented springs generally orthogonal to the longitudinal axis. The transversely oriented springs have different spring rates, so that transverse compression caused by the wearer's thighs may be readily accommodated, yet the spacer remain open to receive fecal material. The spacer may be advantageously used in a disposable absorbent article having a void space between the topsheet and the core, and maintain this void space under the weight of the wearer.
