An absorbent article includes an absorbent core sandwiched between a topsheet and a backsheet, the article being arranged along a longitudinal axis and a transversal axis extending in a perpendicular direction and the article defining a front portion, a back portion and a crotch portion, wherein the absorbent core includes an absorbent component enclosed by a core cover including an upper side and a lower side and the core is formed with a sealing arrangement for joining the upper and lower sides including two channel sealings extending along the longitudinal axis in said crotch portion and defining a first channel sealing width and a second channel sealing width, respectively. Furthermore, the absorbent article includes at least one wetness indicator having a longitudinal extension and being positioned generally only in the front portion, only in the back portion, or in both the front portion and the back portion.

Absorbent article and method for manufacturing an absorbent article

An absorbent article including an absorbent core sandwiched between a liquid-permeable topsheet and a liquid-impermeable backsheet, the article defining a front portion, a back portion and a crotch portion, wherein the absorbent core includes an absorbent component enclosed by a core cover including an upper side and a lower side, and a sealing arrangement for joining the upper and lower core cover sides and including two channel sealings, in the crotch portion, defining a first channel sealing width and a second channel sealing width, and also including two side seams along the sides of the core, wherein a centre segment having a first width is defined in the absorbent component between the channel sealings and two side segments each having a second width are defined in the absorbent component outside each channel sealing.

An absorbent article comprises an absorbent core sandwiched between a liquid-permeable topsheet and a liquid-impermeable backsheet, wherein the absorbent core includes an absorbent component enclosed by a core cover including an upper side and a lower side, each side having a body facing surface and a garment facing surface, and a sealing arrangement for joining the upper and lower sides and including two channel sealings in the crotch portion defining a first channel sealing width and a second channel sealing width. The channel sealings are formed by an ultrasonic welding pattern including a plurality of welding spots and the garment facing surface of the upper core cover side and the body facing surface of the lower core cover side are coated with adhesive, provided that the areas of the channel sealings are free from adhesive.

An absorbent article including an absorbent core sandwiched between a liquid-permeable topsheet and a liquid-impermeable backsheet, wherein the absorbent core includes an absorbent component enclosed by a core cover including an upper side and a lower side, and a sealing arrangement for joining the upper and lower sides and including two channel sealings in the crotch portion defining a first channel sealing width and a second channel sealing width. The channel sealings are formed by thermo and/or mechanical welding pattern including a plurality of welding spots being arranged in the form of a first row along the longitudinal axis in which each welding spot extends along a first axis, and a second row along the longitudinal axis in which each welding spot extends along a second axis, the first axis and second axis defining a first angle in relation to each other.

An absorbent article including a liquid-permeable topsheet, a liquid-impermeable backsheet and an absorbent core sandwiched between the topsheet and the backsheet, the article being arranged along a longitudinal axis and a transversal axis extending in a perpendicular direction in relation to the longitudinal axis and the main article defining a front portion, a back portion and a crotch portion, wherein the absorbent core is formed with a sealing arrangement including two channel sealings extending along the longitudinal axis in the crotch portion and defining a first effective channel sealing width and a second effective channel sealing width, respectively. The sealing arrangement includes two side seams extending along two side edges of the core, the side seams defining a third and fourth effective width, respectively, along the crotch portion and defining a fifth and sixth effective width, respectively, along the front portion and back portion.

An absorbent article comprises an absorbent core sandwiched between a liquid-permeable topsheet and a liquid-impermeable backsheet. The article comprises front, back and crotch portions. The absorbent core comprises an absorbent component having a width in the transversal direction and the absorbent component is enclosed by a core cover comprising an upper side and a lower side. Two channel sealings extend along the longitudinal axis in the crotch portion for joining the upper and lower side of the core cover. A core cover, which is arranged around the absorbent component, defines and limits an expansion space for the centre segment so that the centre segment is prevented from reaching complete expansion to the second volume on wetting, and the ratio of the first width of the centre segment and the width of the absorbent component, in dry condition, is 0.25-0.45.

An absorbent article comprises an absorbent core sandwiched between a topsheet and a backsheet. The article defines a front portion, a back portion and a crotch portion. The absorbent core comprises an absorbent component enclosed by a core cover comprising an upper and a lower side, and the core is formed with a sealing arrangement for joining the upper and lower sides comprising two channel sealings extending along an longitudinal axis in the crotch portion and defining a first channel sealing width and a second channel sealing width, respectively. The front portion of the core is formed with a recess defining a depth extending from a front edge of the core and into the front portion. A distance is defined between said front edge of the core and a front edge of each channel sealing, such that the ratio of the depth and the distance is within the interval 0.05-0.8.
