  • Patent number: 6375646
    Abstract: A disposable, absorbent pants-type diaper includes a front-part (1), a back-part (2), a crotch-part (3) between the front and back parts (1, 2), at least two side-closure parts (12, 13) which mutually join parts of the side-edges (4, 5) of respective front and back parts, so that the pants will present a waist opening (9) and two leg openings (10, 11). The diaper pants further include an elongated absorbent pad (14), an inner casing layer (15), and an outer casing layer (16). At least one of the respective front and back parts (1, 2) has at least one elastically stretchable region (29, 30). The crotch-part (3) is essentially non-stretchable in relation to the stretchable region (29, 30). At least one of respective end-parts (17, 18) of the absorbent pad (14) is disposed within one of the elastically stretchable regions (29, 30), while the center-part (19) of the absorbent pad is disposed within the relatively non-stretchable crotch-part (3) of the pants.

  • Patent number: 6156022
    Abstract: An absorbent article such as a diaper, an incontinence protector or the like, comprises an elongated absorbent body, enclosed between a proximal liquid permeable cover layer and a distal liquid impermeable cover layer. In order to prevent feces from being transferred to a front, urine absorbing area of the article, there is provided a barrier means which comprises at least two, adjacent to each other, strip-shaped elastic elements extending transversely over the inside of the article. The elements in a flat state of the article are pretensioned in their longitudinal direction and at least in the use state of the article, extend backwards and out from the article, relative to a longitudinal edge of the strip-shaped elements facing towards the article.

  • Patent number: 5855574
    Abstract: A method of manufacturing an absorbent article, and an absorbent article, in the form of a pants-type diaper or a sanitary panty, starting from a flat blank which includes an elongated absorbent body enclosed between two casing sheets which at opposing front and rear end parts of the absorbent body have side parts which extend laterally beyond the body on both sides thereof. The method includes the step of folding the blank around a transverse axis so that the end edges of the side parts lie edge-to-edge. At least one folded band of flexible material is placed between each pair of front and rear side parts which lie opposite one another in the folded state of the blank, and the free ends of the bands are fastened to adjacent side parts.

  • Patent number: 5407438
    Abstract: The present invention relates to a casing intended for an absorbent article, such as a disposable diaper, incontinence guard or like article. The casing (1) includes a front-part (5), a rear-part (10) and an intermediate crotch-part (22) made of flexible casing material. According to the invention, an elastic band (14, 15) is provided on each outer edge of the casing sides, at least within the crotch-part of the casing. The elastic band is attached, in a stretched state, to that side of the casing which lies nearest the skin of the user when the absorbent article is worn, by means of a narrow, elongated join. The elastic bands also include parts which extend transversely in relation to respective joins, in a direction from the joins in towards the central part of the casing.
