Absorbent article containment liner and assembly thereof

A containment liner assembly including a front waist area forming a front edge, a back waist area forming a back edge, and a crotch area disposed between the front and back waist areas, the absorbent article having a chassis which includes an absorbent structure and a liquid permeable topsheet, the chassis having opposed first and second longitudinal sides and opposed first and second lateral sides, a containment liner assembly comprising:

• first and second elongated elasticized members adapted to be disposed along the first and second longitudinal sides of the chassis, respectively, with a first end portion of each of the first and second elongated elasticized members coterminous with the back edge, and
• a first containment liner member having opposed first ant second longitudinal ends and opposed inner and outer lateral ends with the first longitudinal end joined with the first elongated elasticized member first end portion and the second longitudinal end joined with the second elongated elasticized member first end portion, the first containment liner member forming a body-adjacent surface for a wearer, the first containment liner member at least in part spaced apart from the chassis to form an opening to a first containment volume formed between the first containment liner and the chassis, the first containment volume comprising a void defined at least in part by the first containment liner member and the chassis and effective to isolate contents of the first containment volume from direct contact with a wearer,
• wherein each of the first and second elongated elasticized members have a second end portion opposite the first end portion with the second end portions adapted to be coterminous with the front edge
• the containment liner assembly additionally comprising a second containment liner member having opposed first and second ends with the second containment liner member first end joined with the first elongated elasticized member second end portion and the second containment liner member second end joined with the second elongated elasticized member second end portion.

A method for providing a containment liner to an absorbent article having a front waist area forming a front edge, a back waist area forming a back edge, and a crotch area disposed between the front and back waist areas, the absorbent article having a chassis which includes an absorbent structure and a liquid permeable topsheet, the chassis having opposed first and second longitudinal sides and opposed first and second lateral sides, said method comprising:

• forming a containment liner assembly by,
• joining a first end of a first containment liner member with a first end portion of a first elongated elasticized member, the first containment liner member forming a body-adjacent surface for a wearer, and
• joining an opposed second end of the first containment liner member with a first end portion of a second elongated elasticized member, and
• joining the containment liner assembly with the chassis by,
• joining the first elongated elasticized member along the first longitudinal side of the chassis such that the first end portion of the first elongated elasticized member is coterminous with the back edge and
• joining the second elongated elasticized member along the second longitudinal side of the chassis such that the first end portion of the second elongated elasticized member is also coterminous with the back edge with which the first end portion of the first elongated elasticized member is coterminous,
• wherein the first containment liner member at least in part is spaced apart from the chassis to form an opening to a first containment volume formed between the first containment liner and the chassis, the first containment volume effective to isolate contents of the first containment volume from direct contact with a wearer, and
• wherein said forming of a containment liner assembly additionally comprises;
• joining a first end of a second containment liner member with a second end portion of a first elongated elasticized member, and
• joining an opposed second end of the second containment liner member with a second end portion of a second elongated elasticized member.

An absorbent article having a body-facing surface, the absorbent article including a front waist area forming a front edge, a back waist area forming a back edge, and a crotch area disposed between the front and back waist areas, the absorbent article having a chassis which includes an absorbent structure and a liquid permeable topsheet, the chassis having opposed first and second longitudinal sides and opposed first and second lateral sides, the absorbent article additionally comprising:

• a first elongated elasticized member disposed along the first longitudinal side of the chassis,
• a second elongated elasticized member disposed along the second longitudinal side of the chassis,
• wherein each of the first and second elongated elasticized members having a first end portion coterminous with the front edge and a second end portion coterminous with the back edge;
• a first containment liner member having opposed first and second ends with the first end joined with the first elongated elasticized member first end portion and the second end joined with the second elongated elasticized member first end portion, the first containment liner member at least in part forming a first portion the body-facing surface of the absorbent article, wherein the first containment liner member and the chassis cooperate to form a first containment volume therebetween adjacent the front edge and wherein the first containment liner member has a longitudinal length which is in the range of about 10 to about 50 percent of the longitudinal length of the chassis, and
• a second containment liner member having opposed first and second ends with the first end joined with the first elongated elasticized member second end portion and the second end joined with the second elongated elasticized member second end portion, the second containment liner member at least in part forming a second portion of the body-facing surface of the absorbent article, wherein the second containment liner member and the chassis cooperate to form a second containment volume therebetween adjacent the back edge and wherein the second containment liner member has a longitudinal length which is in the range of about 10 to about 35 percent of the longitudinal length of the chassis.
