Patent number: 6602237Abstract: An absorbent product includes an absorbent portion with an absorbent body between a liquid permeable sheet and a liquid impermeable sheet, and flexible flaps projecting from tapering longitudinal edges of the absorbent portion. A first removable protective layer covers substantially the entire absorbent portion and second and third removable protective layers each cover substantially all of a respective one of the flexible flaps. Each of the second and third protective layers is directly opposite the first protective layer along substantially an entire length of a first line along the respective longitudinal edge of the absorbent portion. The second and third protective layers are at least partially separated from the first protective layer by a cut line that follows the respective first line.Type: GrantFiled: February 25, 2002Date of Patent: August 5, 2003Assignee: SCA Hygiene Products ABInventors: Bror-Inge Helmfridsson, Hakan Persson, Solgun Drevik, Frantisek Solar

Patent number: 6569138Abstract: 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.Type: GrantFiled: April 12, 2001Date of Patent: May 27, 2003Assignee: SCA Hygiene Products ABInventors: Bror-Inge Helmfridsson, Solgun Drevik

Patent number: 6524422Abstract: 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.Type: GrantFiled: April 13, 2001Date of Patent: February 25, 2003Assignee: SCA Hygiene Products ABInventors: Bror-Inge Helmfridsson, Hakan Persson, Solgun Drevik, Frantisek Solar

Patent number: 6452064Abstract: A method of manufacturing a fluid permeable covering sheet (9) for an absorbent article such as a diaper, a sanitary napkin, an incontinence protector or the like, wherein heated needles (4) are brought to penetrate a sheet of textile material (1) comprising at least one thermoplastic component, whereby the thermoplastic component closest to the needles (4) melts, whereafter the needles (4) are removed and the heated material (1) is passed through at least one nip of rollers (7) so that the thermoplastic component closest around the apertures is smoothed out into a substantially smooth material surface around the apertures, whereafter the thermoplastic component is brought to solidify. The invention further pertains to an apertured covering sheet (201, 301) for an absorbent article manufactured in accordance with the method, and an absorbent article (300) provided with a covering sheet manufactured in accordance with the method.Type: GrantFiled: December 13, 1999Date of Patent: September 17, 2002Assignee: SCA Hygiene Products ABInventors: Agneta Thoren, Bror-Inge Helmfridsson
