Abstract

The invention relates to an absorbent core (3), intended for use in an absorbent product such as a panty liner. The core (3) comprises an absorbent material and a superabsorbent material. The core (3) has a first extension in a longitudinal direction and a second extension in a transverse direction, and the core has a longitudinal central line (A) extending through the core, located between a first longitudinal portion (I) and a second longitudinal portion (II). The first and second longitudinal portions (I; II) are symmetric about the longitudinal central line (A). The core has a head portion (al), an intermediate portion (a2) and a rear portion (a3) extending in a longitudinal direction of the core. The head portion (al) comprises mirror imaged first circular segment portions (11; 11') and first edge lines (13; 13') to which the circular segment portions (11, 11') transition. The intermediate portion (a2) comprises mirror imaged first convex edge portions (15; 15'). The rear portion (a3) comprises second edge lines (17; 17') tapering towards a rear end (T5) and the central line (A) of the core in an angle ([gamma]).

Description

technical field

[0001] The present invention relates to an absorbent core intended for use in absorbent products such as pantiliners. The core comprises absorbent material with absorbent properties and superabsorbent material. The core has a first extension dimension in the longitudinal direction and a second extension dimension in the transverse direction, and the core has a longitudinal centerline extending through the core and positioned between the first longitudinal portion and the second longitudinal portion. The first and second longitudinal sections are symmetrical about a longitudinal centerline. The core has a head, a middle portion and a rear portion extending longitudinally of the core.

[0002] The invention also relates to a method for manufacturing an absorbent core. Background technique

[0003] Panty liners are absorbent products used to absorb small amounts of body fluids such as urine and blood. Panty liners are smaller in size than menstrual pads or i...

Embodiment Construction

[0035] figure 1 is a schematic view of an absorbent core 3 according to the invention, seen from above. The core 3 comprises absorbent material and superabsorbent material having absorbent properties. The core has a first extension in the longitudinal direction and a second extension in the transverse direction. The core has a longitudinal centerline A extending through the core. The longitudinal centerline A is located between the first longitudinal section I and the second longitudinal section II. The first and second longitudinal sections I, II are symmetrical about a longitudinal centerline A. The core has a head a1 , a middle part a2 and a rear a3 extending longitudinally of the core 3 from the front of the core 3 to the rear of the core 3 . The longitudinal extension of the head a1 is about 1 / 4 of the longitudinal extension of the core 3, the longitudinal extension of the middle part a2 is about 1 / 2 of the longitudinal extension of the core 3 and the longitudinal exten...
