Abstract
An absorbent core and method of manufacturing an absorbent core for use with various absorbent articles comprising a top sheet layer, a back sheet layer and an absorbent core located between at least portions of the top sheet layer and back sheet layer. The absorbent core incorporates a C-shaped fluid barrier material surrounding at least the back sheet facing surface and side surfaces of the absorbent core. One or more fluid acquisition layers may reside over the absorbent core between the core and the top sheet layer. One or more fluid management layers may also reside within the core.
Claims48
An absorbent article comprising:
- a back sheet layer;
- a top sheet layer;
- an absorbent core comprising synthetic fibers disposed at least partially between the back sheet layer and the top sheet layer;
- a C-shaped fluid impervious layer that surrounds at least the back sheet facing surface of the absorbent core and side surfaces of the core;
- and
- a fluid pervious layer that covers at least a portion of the top sheet layer facing surface of the core.
An absorbent core for use with an absorbent article comprising:
- a volume of synthetic absorbent material defined by a top body facing surface, a bottom outer facing surface and side surfaces, wherein at least a portion of the top body facing surface comprises a fluid pervious layer and the remaining surfaces comprise a fluid impervious layer.
A method of manufacturing an absorbent article comprising:
- providing a top sheet layer;
- providing a back sheet layer;
- providing an absorbent core comprising synthetic fibers disposed at least partially between the top sheet layer and the back sheet layer as an absorbent article;
- providing a fluid permeable layer over at least a portion of the top sheet layer facing surface of the core;
- and
- providing a fluid impermeable layer over at least some of the remaining surfaces of the core, thereby encasing the core in a combination of fluid permeable and fluid impermeable materials.
An absorbent article having a C-folded absorbent core comprising:
- a back sheet layer;
- a top sheet layer;
- an absorbent core comprising synthetic fibers at least partially disposed between at least portions of the top sheet layer and the back sheet layer;
- a fluid pervious layer covering at least a portion of the surface of the absorbent core facing the top sheet layer;
- and
- a fluid impervious layer covering at least some of the remaining surfaces of the absorbent core, wherein the fluid impervious layer comprises a C-like cross sectional shape surrounding the absorbent core.
