  • Patent number: 6569138
    Abstract: An absorbent article includes an absorbent body enclosed between a liquid-permeable outer sheet and a liquid-impermeable outer sheet, a front part facing forwards when the article is worn, and a rear part. The absorbent body tapers rearwardly to the end of the rear part from a section of greatest width situated in said front part. The article includes flexible outwardly projecting flaps which extend on respective sides of the absorbent body and have outer edges that are inclined relative to the longitudinal symmetry axis at an angle such that the distance between the outer sides of said flaps and the axis decreases in a direction towards the rear end of the article. At least two adhesive strings are applied to at least one of the flaps on the side thereof which, in the unfolded state of the flap, lies on the same side of the article as the liquid-impermeable outer sheet.

  • Patent number: 6554812
    Abstract: An absorbent article includes outwardly projecting, flexible flaps which extend beyond respective sides of an absorbent body along a tapering part of the body and have outer longitudinal edges which in the unfolded state of the flaps are inclined relative to the longitudinal symmetry axis (A—A) of the article at an angle &agr; such that the distance between the outer sides of the flaps and the longitudinal symmetry axis of the article decreases in a direction towards the rear end of the article. The angle (&agr;) is larger than the angle (&bgr;) at which a first imaginary line inclined to the longitudinal symmetry axis, and passing through the outer limitation point of the absorbent body in its widest part and the outer transversal limitation point of the rear end of the absorbent body.

  • Patent number: 6524422
    Abstract: A method of manufacturing absorbent articles (17) in the form of sanitary napkins, panty liners or incontinence protectors for women, includes the step of cutting a web (5) of protective layer material with a sequence of pairs of cuts (8, 9) which are so spaced apart so that when the web (5) of protective layer material is placed on a web (1, 3, 4) of article blanks the two cuts (8, 9) in each pair of cuts in the sequence of pairs of cuts will lie linearly between the points of connection of flaps (23, 24) with the longitudinal edges of each article. The thus cut web (5) of protective layer material is then placed on the web (1, 3, 4) of article blanks and individual articles (17) are cut from the composite web (1, 3, 4, 5) in a second cutting step that defines the periphery of the articles.

  • Patent number: 6482193
    Abstract: An absorbent article intended for female users, has such a form and size that it can principally be accommodated in the crotch part of a pair of underpants, a longitudinal direction, a transverse direction and a thickness direction. The article displays a liquid-permeable surface (2), and a liquid-impermeable surface (3), and also an absorbent core consisting of at least one absorbent body (5) arranged between the two surfaces (2, 3). A raised portion (7) extending in the longitudinal direction and displaying two end portions is arranged at the liquid-permeable surface (2) of the article. The raised portion (5) displays spacing elements (16) which during use of the article create channels (17) for the flow of liquid between the raised portion (5) and the body of the user.
