An absorbent core, intended for use in an absorbent product such as a panty liner, is disclosed, comprising an absorbent material and a superabsorbent material. The core has a first extension in a longitudinal direction and a second extension in a transverse direction, and a longitudinal central line extending through the core, located between a first longitudinal portion and a second longitudinal portion. The first and second longitudinal portions are symmetric about the longitudinal central line. The core has a head portion, an intermediate portion and a rear portion extending in a longitudinal direction of the core. The head portion includes mirror imaged first circular segment portions and first edge lines to which the circular segment portions transition. The intermediate portion includes mirror imaged first convex edge portions. The rear portion includes second edge lines tapering towards a rear end and the central line of the core in an angle. |

1: An absorbent core, intended for use in an absorbent product, comprising:
an absorbent material with absorbent characteristics; a superabsorbent material; a first extension in a longitudinal direction; a second extension in a transverse direction; a longitudinal central line extending through the core and located between a first longitudinal portion and a second longitudinal portion, which first and second longitudinal portions are symmetric about the longitudinal central line; and a head portion, an intermediate portion, and a rear portion extending in a longitudinal direction of the core,
wherein the head portion comprises, in the respective first and second longitudinal portions, mirror imaged:
first circular segment portions extending in a longitudinally forward direction of the core from a first transition point, located on the central line between the circular segment portions, in an acute angle β between the central line and a tangent at the first transition point in respect of the circular segment portion; andfirst edge lines, to which the circular segment portions transition, tapering towards the intermediate portion and towards the central line of the core in an angle α being from 15-45°, and wherein the first edge lines taper to a second transition point located between the head portion and the intermediate portion,wherein the intermediate portion comprises, in the respective first and second longitudinal portions, mirror imaged:
first convex edge portions extending between the second transition points and third transition points, which third transition points are located between the intermediate portion and the rear portion, wherein the length of the convex edge portions in respect to the central line is from 50-60% of the total length of the central line and have a maximum height of the arch of the each of the first convex edge portions in the transverse direction of the core of from 1-10 mm; andthe rear portion comprises second edge lines tapering towards a rear end point and the central line in an angle γ being from 3-15°, and wherein the second edge lines taper to a fourth transition point from which the second edge lines transition to a rear end portion that joins the edge lines together. |
