  • Publication number: 20090157028
    Abstract: An absorbent garment having belt sections attached to the waist portion of a first body panel and fastened together by a first fastener, a second body panel at its waist portion being provided with a second fastener adapted to be fastened to at least one of the belt sections; wherein when the absorbent garment is tested by: (a) fastening a belted absorbent garment around movable mechanical members which are adapted to mechanically simulate a user's waist or hips; and (b) moving said members away from each other using actuating members and moving them back to their initial position so as to simulate the expansion and contraction of a user's waist as he/she moves; the garment does not slip down more than 15 cm from its initial position during at least ten expansion/contraction cycles of the test apparatus and for at least 30 seconds.

  • Publication number: 20090107614
    Abstract: Disposable hygiene pants with a front portion (2), a rear portion (3) and a crotch portion (4) provided with two leg openings (5, 6), the longitudinal edge portions (21, 22) of the front portion being connected by longitudinal weld seams (7, 8) to the longitudinal edge portions (31, 32) of the rear portion (3) in order to form a waist opening (9) and two leg openings (5, 6) in the crotch portion, which leg openings are outwardly delimited in the transverse direction by the inner end portions of the weld seams as seen in the longitudinal direction of the hygiene pants. The hygiene pants have an outer cover (10) and comprise an absorption unit (11). The cover is preferably made of an elastic laminate. The weld seams (7, 8) are each reinforced by at least one reinforcing strip (15, 16) containing thermoplastic fibers and have a tensile strength, in a direction transverse to the weld seam, in excess of 5 N/25.4 mm at least in the portions reinforced with said nonwoven strip (15, 16).

  • Patent number: 6726670
    Abstract: A belted absorbent article (10) having an absorbent structure (16) and a pair of opposed belt halves (12, 14) attached to the absorbent structure (16) via a respective joint (50). The joint (50) between each belt half (12, 14) and the absorbent structure (16) is designed such that when each belt half is subjected to a tension force of 35 N acting along the belt half and the direction of applied tension creates an angle (&agr;) to the transverse axis (T) of the absorbent structure, the following minimum average release times (t) of each belt half from the absorbent structure are attained: when &agr;=10°, t>>720 seconds; when &agr;=20°, t>>330 seconds; when &agr;=25°, t>>240 seconds; when &agr;=30°, t>>180 seconds; and when &agr;=40°, t>>75 seconds.

  • Publication number: 20030014033
    Abstract: A sanitary, absorbent article includes a hooks and loops type fastener for releasably attaching a first and a second part of the article to each other, wherein the first part is overlapping the second part when the parts are attached to each other, with a hooks member affixed to said first part of the article and a loops member affixed to the second part of the article. Each member has a base portion having a bottom surface affixed to the first or second part of the article and an opposite top surface containing hooks elements and loops elements, respectively. The fastener can include a first end region distal to the overlapping edge of the first part, in which the engagement force between the hooks and loops element of the members is reduced.
