  • Publication number: 20150329257
    Abstract: A package with a stack of flexible articles includes a stack of flexible articles, a flexible outer cover, having a first end side panel and a second end side panel opposing the first end side panel. The package further includes two and preferably only two stiffening elements that are stiffer than the flexible outer cover and the flexible articles, whereby one of the stiffening elements is positioned against the interior surface of the end side panels of the outer cover and the other stiffening element is positioned against the opposing end side panel of the outer cover.

  • Patent number: 8721611
    Abstract: Absorbent article, in particular a diaper or an incontinence product, includes an absorbent structure (1) including a back-sheet (20), a top-sheet (22) and an absorbent core (24) there between. The absorbent structure (1) has a front portion (10) defining a front lateral edge (16), a rear portion (14) defining a rear lateral edge (18) and a crotch portion (12) situated between the front portion and the rear portion. A pair of belt sections (30, 32) is present for fastening the absorbent article to the waist of a wearer, the belt sections being fixedly attached to the rear portion of the absorbent structure. The absorbent article has a maximum lateral extension B between the respective lateral-most edges (302, 322) of the belt sections that is governed by the following expression: 0.3<A/B<0.7 where A is the maximum lateral extension of the front lateral edge of the absorbent structure.

  • Patent number: 8153856
    Abstract: An absorbent article is defined by a pair of opposing longitudinal edges 20;22 and a pair of opposing transverse edges 24;26. An absorbent core 18 has at least a first 28 and a second 30 region, the average density of the absorbent core 18 in these first and second regions 28, 30 being lower than the average density of the absorbent core 18 surrounding said first and second regions 28;30, the first and second lower density regions 28;30 being arranged symmetrically about the longitudinal center line A of the article such that each of the first and second lower density regions 28;30 extends to the respective longitudinal edge 20;22 of the absorbent core. The distance ax varying along the longitudinal direction of the article. A minimum distance a1 is located at least in the transition 32 between the crotch portion 14 and the front portion 12.

  • Patent number: 7825291
    Abstract: An absorbent article 10 has front 12, crotch 14 and rear 16 portions. The article has an absorbent core 18 of unitary construction and of uniform density, which is defined by a pair of opposing longitudinal edges 20;22 and a pair of opposing transverse edges 24;26. The absorbent core 18 has at least a first 28 and a second 30 region, the average thickness of the absorbent core 18 in these first and second regions 28, 30 being lower than the average thickness of the absorbent core 18 surrounding the first and second regions 28;30, the first and second lower thickness regions 28;30 being arranged symmetrically about the longitudinal center line A of the article such that each of the first and second lower thickness regions 28;30 extends to the respective longitudinal edge 20;22 of the absorbent core. The distance ax between the first and second lower thickness regions 28;30 in the transverse direction varying along the longitudinal direction of the article.
