  • Patent number: 10159608
    Abstract: An absorbent article such as a sanitary napkin or incontinence pad has longitudinal side edges, transversal end edges, a fluid permeable topsheet, a fluid impermeable backsheet and an absorbent core located between the topsheet and the backsheet. The absorbent core includes a first absorbent layer having an opening extending therethrough and a fluid flow control structure located between said first absorbent layer and said backsheet. The first absorbent layer has a longitudinal front portion and a longitudinal back portion and a narrow transversal transition located between said front portion and said back portion. The width of the narrow transversal transition is 50-75% of the widest transversal width of the front portion of the first absorbent layer and 20-50% of the longitudinal length of the opening is located in the front portion of the first absorbent layer.

  • Patent number: 9259361
    Abstract: An absorbent article has longitudinal side edges, transversal end edges, and an absorbent core. The absorbent core comprises a first absorbent layer having an opening and a fluid flow control structure between said first absorbent layer and a backsheet. An elastic member is arranged along each longitudinal side edge. The first absorbent layer has a longitudinal front portion, a longitudinal back portion and a narrow transversal transition located between said front and back portions. The width of the narrow transversal transition is 50-75% of the widest transversal width of the front portion, and 20-50% of the longitudinal length of the opening is located in the front portion. The front portion constitutes 20-40% of the total longitudinal length of the first absorbent layer. An interspace is located in an area between the elastic member and the first absorbent layer at least in an area laterally outside the narrow transversal transition.

  • Patent number: 9125774
    Abstract: An absorbent article package (1) including an absorbent article (2) and a wrapper (3). The absorbent article (2) includes a backsheet (4), a liquid permeable first layer (5) and an absorbent body (6) therebetween. The wrapper (3) includes an inner surface (11) facing the absorbent article (2) and an outer surface (12) facing away from the absorbent article (2). The absorbent article (2) includes a first leakage barrier side (13) positioned along at least a part of a first longitudinal side edge (7) and a second leakage barrier side (14) positioned along at least a part of a second longitudinal side edge (8). The wrapper (3) includes a first and a second flap (16, 17) being folded over the liquid permeable first layer (5) and attached to each other securing each of the first and second leakage barrier sides (13, 14) in a folded position over a part of the liquid permeable first layer (5).

  • Publication number: 20110114660
    Abstract: A dispenser of absorbent articles in a stack or a roll. At least a portion of each absorbent article is covered by a cover wrapper. The dispenser includes a housing, the housing including, inter alia, a friction element which is arranged to make contact with the cover wrapper of a leading absorbent article and deliver it towards the outlet of the dispenser. The friction element has a friction material including that surface of the friction element which is arranged to make contact with the cover wrapper. The friction material has a static coefficient of friction against the surface of the cover wrapper which has a minimum value, so that effective and reproducible dispensing of the absorbent articles is achieved.
