Abstract
An absorbent article such as a diaper, training pant, and the like comprises a containment member that has a central zone and a barrier zone. The central zone has greater air flow according to the Air Permeability Test than the barrier zone. The barrier zone a greater hydrohead according to the Hydrostatic Head Pressure Test than the central zone. The containment member may be used for absorbent core formation and may have portions configured to serve as barrier leg cuffs for the finished absorbent article.
Claims20
An absorbent article comprising a garment body and an absorbent assembly joined to the garment body such that the absorbent assembly is disposed between the garment body and a wearer during wear, wherein said absorbent assembly has a garment-facing surface and a body-facing surface, wherein said absorbent assembly comprises:
- a) a liquid permeable topsheet,
- b) a containment member joined to the topsheet, and
- c) an absorbent core disposed between said containment member and said topsheet, said absorbent core having opposing longitudinal core edges;
- wherein the containment member is formed of a continuous substrate and comprises:
- i) respective opposing longitudinal containment member edges and a pair of elastic members respectively joined proximate to the containment member edges;
- ii) a central zone disposed between the absorbent core and the garment body;
- and
- iii) a pair of barrier zones respectively disposed at either longitudinal side of the central zone, between the central zone and the opposing containment member edges, the barrier zones and the containment member edges forming respective upstanding longitudinal barrier cuffs, and
- wherein the central zone has a greater air flow according to the Air Permeability Test than the barrier zones and the barrier zones have a greater hydrohead according to the Hydrostatic Head Pressure Test than the central zone;
- and the central zone has an air flow of at least about 100 m3/m2/min at a pressure drop of 125 Pa.
An absorbent article comprising a garment body and an absorbent assembly joined to the garment body such that the absorbent assembly is disposed between the garment body and a wearer during wear, wherein said absorbent assembly has a garment-facing surface and a body-facing surface, wherein said absorbent assembly comprises:
- a) a liquid permeable topsheet,
- b) a containment member joined to the topsheet,
- c) an absorbent core disposed between said containment member and said topsheet, said absorbent core having opposing longitudinal core edges;
- wherein the containment member is formed of a continuous substrate and comprises:
- i) respective opposing longitudinal containment member edges and a pair of elastic members respectively joined proximate to the containment member edges;
- ii) a central zone disposed between the absorbent core and the garment body;
- and
- iii) a pair of bond zones respectively disposed adjacent to the elastic members, and
- iv) a pair of barrier zones respectively disposed at either longitudinal side of the central zone, between the central zone and the opposing containment member edges, the barrier zones and the containment member edges forming respective upstanding longitudinal barrier cuffs:
- wherein the central zone has a greater air flow according to the Air Permeability Test than the barrier zones;
- wherein the bond zones have a greater hydrohead according to the Hydrostatic Head Pressure Test than the barrier zones;
- and the central zone has an air flow of at least about 100 m3/m2/min at a pressure drop of 125 Pa.
An absorbent article comprising a garment body and an absorbent assembly joined to the garment body such that the absorbent assembly is disposed between the garment body and a wearer during wear, wherein the garment body consists essentially of a liquid permeable material, wherein said absorbent assembly has a garment-facing surface and a body-facing surface, wherein said absorbent assembly comprises:
- a) a liquid permeable topsheet,
- b) a containment member, and
- c) an absorbent core disposed between said containment member and said topsheet, said absorbent core having opposing longitudinal core edges;
- wherein the containment member is formed of a continuous substrate and comprises:
- i) respective opposing longitudinal containment member edges and a pair of elastic members respectively joined proximate to the containment member edges;
- ii) a central zone disposed between the absorbent core and the garment body,
- iii) a pair of barrier zones respectively disposed at either longitudinal side of the central zone, between the central zone and the opposing containment member edges, the barrier zones and the containment member edges forming respective upstanding longitudinal barrier cuffs, and
- wherein the central zone has a greater air permeability than the barrier zones and the barrier zones have a greater hydrohead than the central zone;
- and the central zone has an air flow of at least about 100 m3/m2/min at a pressure drop of 125 Pa.
