Abstract
An absorbent article having a first liquid permeable surface layer, a essentially liquid impermeable backing layer and, located between said liquid permeable surface layer and said liquid impermeable backing layer, an absorbent body having at least one layer. The absorbent article has cavities which are essentially cone-shaped and extend at least through part of the absorbent body, said cavities having a tip part and a base, the tip part being located towards or in the liquid permeable surface layer and the base being located away from the liquid permeable surface layer. A method of production of an absorbent article with cone-shaped cavities is also provided.
Claims31
An absorbent article comprising:
- a first liquid permeable surface layer;
- a substantially liquid impermeable backing layer;
- and
- an absorbent body located between the liquid permeable surface layer and the substantially liquid impermeable backing layer, the absorbent body including at least one layer,
- wherein the absorbent article includes at least one cavity which is substantially cone-shaped and extends at least through part of the absorbent body, the cavity having a tip part and a base, the tip part being located towards or in the liquid permeable surface layer and the base being located away from the essentially liquid permeable surface layer.
A method of manufacturing a breathable absorbent article, the method comprising:
- locating an absorbent body on a backing layer, the absorbent body including at least one layer and having a first and a second surface;
- perforating the backing layer and at least part of the absorbent body so that the backing layer and the at least part of the absorbent body are provided with cavities, the cavities being substantially cone-shaped and extending in a tapering manner from the backing layer towards the first surface of the absorbent body;
- locating a liquid permeable surface layer on the first surface of the perforated absorbent body, the absorbent body lying between the liquid permeable surface layer and the perforated backing layer;
- and
- joining the liquid permeable surface layer and the backing layer.
A method of manufacturing a breathable absorbent article, the method comprising:
- locating an absorbent body on a backing layer, the absorbent body including at least one layer and having a first and a second surface, wherein the second surface of the absorbent body faces the backing layer;
- locating a liquid permeable surface layer on the first surface of the absorbent body, the absorbent body lying between the liquid permeable surface layer and the backing layer;
- perforating the backing layer and at least part of the absorbent body so that the backing layer and the at least part of the absorbent body are provided with cavities, the cavities being substantially cone-shaped and extending in a tapering manner from the backing layer and the second surface of the absorbent body towards the first surface of the absorbent body;
- and
- joining the liquid permeable surface layer and the backing layer.
A method of manufacturing a breathable absorbent article, the method comprising:
- perforating an absorbent body so that at least part of the absorbent body is provided with cavities, the absorbent body including at least one layer and having a first and a second surface and the cavities being substantially cone-shaped and extending in a tapering manner from the second surface of the absorbent body towards the first surface of the absorbent body;
- locating the second surface of the absorbent body against a liquid impermeable backing layer;
- locating a liquid permeable surface layer on the first surface of the absorbent body, the absorbent body lying between the surface layer and the backing layer;
- and
- joining the liquid permeable surface layer and the backing layer.
A method of manufacturing a breathable absorbent article, the method comprising:
- providing an absorbent body, the absorbent body including at least one layer and a first surface and a second surface;
- locating the second surface of the absorbent body against a liquid impermeable backing layer;
- locating a liquid permeable surface layer on the first surface of the absorbent body, the absorbent body lying between the surface layer and the backing layer;
- joining the liquid permeable surface layer and the backing layer;
- and
- perforating the backing layer and at least part of the absorbent body so that the backing layer and the at least part of the absorbent body are provided with cavities, the cavities being essentially cone-shaped and extending in a tapering manner from the backing layer and the second surface of the absorbent body towards the first surface of the absorbent body.
