Abstract

A disposable wearable absorbent article comprises a chassis having an absorbent core and first and second side panels extending transversally outwards towards respective outer edges. Each of the first and second side panels comprises a mechanical fastening material affixed to an outer end portion of the panel whereby, in use, the first and second side panels can extend around a user's waist to couple the first and second side panels to the chassis. Each of the side panels is gathered in a longitudinal direction to form at least one pleat extending in the transverse direction, and comprises a binding material affixed to respective side panels to maintain each of the first and second side panels in a gathered configuration. A method for forming disposable wearable absorbent articles is also disclosed.

Dependent claims

A disposable wearable absorbent article comprising:

a chassis extending in a longitudinal direction and having a front region, a rear region and a central region disposed in the longitudinal direction between the front region and the rear region, the central region comprising an absorbent core;
a first side panel connected to the chassis and extending transversally outwards in a first lateral direction towards a first outer edge;
a second side panel connected to the chassis and extending transversally outwards in a second lateral direction towards a second outer edge;
wherein each of the first and second side panels comprises a mechanical fastening material affixed to a free end portion adjacent the outer edge of the each of the first and second side panels, whereby, in use, the first and second side panels can extend around a user's waist to couple the first and second side panels to the front region of the chassis, and
wherein each of the first and second side panels is gathered in a longitudinal direction to form at least one pleat extending in a transverse direction, and
wherein each of the first and second panels comprises a binding material affixed thereto, the binding material being configured to maintain each of the first and second side panels in a gathered configuration.
