Absorbent article with partially enclosed waist containment member and method of manufacturing thereof
An absorbent article ( 10, 110 ) can include a waist containment member ( 54 ) with a first longitudinal side edge ( 72 ), a second longitudinal side edge ( 74 ), a proximal portion ( 76 ), an intermediate portion ( 77 ), and a distal portion ( 78 ). The proximal portion ( 76 ) can be coupled to the chassis ( 11 ) of the absorbent article ( 10, 110 ). The intermediate portion ( 77 ) can be free to move independent of the proximal portion ( 76 ) and the distal portion ( 78 ) and free to move independent of the body facing surface ( 19 ) of the chassis ( 11 ) to provide a containment pocket ( 82 ) for containing body exudates. The distal portion ( 78 ) can be disposed underneath the intermediate portion ( 77 ) when the absorbent article ( 10, 110 ) is in the stretched, laid-flat configuration. The waist containment member ( 54 ) can also include a first lateral tack-down region ( 83 a ) and a second lateral tack-down region ( 83 b ).
1. A method of manufacturing an absorbent article, the absorbent article including a front waist region, a rear waist region, a crotch region, a longitudinal axis and a lateral axis, the method comprising:
moving a chassis including a body facing surface in a machine direction, the chassis comprising an absorbent assembly including a bodyside liner, an outer cover, and an absorbent body disposed between the bodyside liner and the outer cover, the absorbent assembly including a body facing surface;
moving a continuous web of waist containment member material in the machine direction;
folding at least a first portion of the continuous web of waist containment member material upon itself to provide a folded edge;
cutting the continuous web of waist containment member material to provide a waist containment member including a proximal portion, an intermediate portion, a distal portion, a first longitudinal side edge, a second longitudinal side edge, an upper lateral edge, and a lower lateral edge, the intermediate portion being disposed between the proximal portion and the distal portion;
bonding the proximal portion of the waist containment member to the body facing surface of the chassis;
bonding the distal portion of the waist containment member to the body facing surface of the chassis to provide a first lateral tack-down region near the first longitudinal side edge of the waist containment member and a second lateral tack-down region near the second longitudinal side edge of the waist containment member,
wherein the intermediate portion comprises a number of layers of material greater than a number of layers of material of the proximal portion such that the intermediate portion is thicker than the proximal portion.
2. The method of manufacturing an absorbent article of claim 1 , further comprising bonding the proximal portion, the intermediate portion, and the distal portion of waist containment member to the body facing surface of the chassis to provide the first longitudinal tackdown region near the first longitudinal side edge and the second longitudinal tack-down region near the second longitudinal side edge.
3. The method of manufacturing an absorbent article of claim 1 , further comprising:
providing a pair of containment flaps including a first containment flap and a second containment flap, the first containment flap and the second containment flap each including a base portion and a projection portion; and
bonding the base portion of each of the first and the second containment flaps to the body facing surface of the absorbent assembly, the base portion of each of the first and the second containment flaps each including a proximal end and a distal end.
4. The method of manufacturing an absorbent article of claim 3 , wherein the first lateral tack-down region comprises the distal portion of the waist containment member being coupled to the body facing surface of the chassis from the first longitudinal side edge to at least the proximal end of the base portion of the first containment flap and the second lateral tack-down region comprises the distal portion of the waist containment member on the second side of the longitudinal axis being coupled to the body facing surface of the chassis from the second longitudinal side edge to at least the proximal end of the base portion of the second containment flap.
5. The method of manufacturing an absorbent article of claim 1 , wherein the folded edge defines the lower lateral edge of the waist containment member when the absorbent article is in a stretched laid-flat configuration.
6. The method of claim 1 , wherein bonding the distal portion of the waist containment member to the body facing surface of the chassis further comprises bonding the distal portion of the waist containment member to the body facing surface of the chassis such that the intermediate portion is free to move independent of the proximal portion and the distal portion and free to move independent of the body facing surface of the chassis to provide a containment pocket for containing body exudates.
7. The method of claim 1 , wherein the folded edge comprises the distal portion, and wherein bonding the distal portion of the waist containment member to the body facing surface of the chassis further comprises bonding the distal portion of the waist containment member to the body facing surface of the chassis such that the distal portion is disposed underneath the intermediate portion when the absorbent article is in a stretched laid-flat configuration.
8. The method of claim 1 , wherein the folded edge comprises the proximal portion which defines a juncture between the proximal portion and the intermediate portion and which defines the upper lateral edge of the waist containment member.
