Abstract

Absorbent articles having side panels that provide inflected barrier cuffs which promote better containment and fit. The absorbent article has a front waist region, a rear waist region, a crotch region and a pair of longitudinal edges. The absorbent article further comprises a chassis including a pair of longitudinally extending side panels, each of the side panels having a front ear flap section; a barrier cuff section having a first end edge located longitudinally inboard of the front ear flap section; a second end edge located in the rear waist region; a proximal edge and a distal edge; spacing means joined with each barrier cuff section; and closing means for securing at least a portion of the barrier cuff section juxtaposed the first end edge to the absorbent article inboard of the proximal edge. The distal edges are unsecured to any underlying structure of the absorbent article in the front and rear waist regions such that the distal edges form the longitudinal edges in the front and rear waist regions. The distal edge of the barrier cuff section is secured laterally inboard of the proximal edge in the crotch region such that the second end edges of the side panels located in the rear waist region are inverted relative to the first end edges to form an inflected barrier cuff that stands up in the crotch region when the absorbent article is fitted to a wearer.

Claims

1. A disposable absorbent article having a front waist region, a rear waist region, a crotch region between said front waist region and said rear waist region, a pair of longitudinal edges, a lateral centerline and a longitudinal centerline, the absorbent article comprising:

a chassis comprising a liquid pervious topsheet;

a liquid impervious backsheet joined with said topsheet;

an absorbent core interposed between said topsheet and said backsheet, said absorbent core having a pair of opposed side edges, a pair of longitudinally extending side panels, each of said side panels including a front ear flap section located in said front waist region;

a barrier cuff section having a first end edge located longitudinally inboard of said front ear flap section;

a second end edge located in said rear waist region;

a proximal edge disposed adjacent one of said side edges of said absorbent core and a distal edge spaced apart from said proximal edge;

spacing means joined along said distal edge of each said barrier cuff section; and

closing means for securing at least a portion of said barrier cuff section juxtaposed said first end edge to the absorbent article inboard of said proximal edge;

said distal edges being unsecured to any underlying structure of the absorbent article in said front waist region and said rear waist region such that said distal edges form said longitudinal edges in said front waist region and said rear waist region; and

said distal edge of said barrier cuff section being secured laterally inboard of said proximal edge in said crotch region such that said second end edges of said side panels located in said rear waist region are inverted relative to said first end edges to form an inflected barrier cuff that stands up in said crotch region when the absorbent article is fitted to a wearer.

2. The absorbent article of claim 1 additionally comprising an ear flap joined to and extending outwardly from each said side panel in the rear waist region.

3. The absorbent article of claim 2 wherein said ear flaps additionally comprise a fastening means for securing the absorbent article about the waist of the wearer.

4. The absorbent article of claim 3 wherein said fastening means comprises a tape tab having one end secured to said ear flap and a second end for attachment to said front waist region.

5. The absorbent article of claim 2 wherein said ear flaps comprise a stretch laminate comprising a layer of elastomeric film sandwiched between two layers of nonwoven fabric.

6. The absorbent article of claim 1 wherein said side panels are z-folded in at least said barrier cuff section.

7. A disposable absorbent article having a front waist region, a rear waist region, a crotch region between said front waist region and said rear waist region, a pair of longitudinal edges, a lateral centerline and a longitudinal centerline, the absorbent article comprising:

a chassis comprising a liquid pervious topsheet;

a liquid impervious backsheet joined with said topsheet;

an absorbent core interposed between said topsheet and said backsheet, said absorbent core having a pair of opposed side edges, a pair of longitudinally extending side panels, each of said side panels including a front ear flap section located in said front waist region;

a barrier cuff section having a first end edge located longitudinally inboard of said front ear flap section;

a second end edge located in said rear waist region;

a proximal edge disposed adjacent one of said side edges of said absorbent core and a distal edge spaced apart from said proximal edge;

spacing means joined along said distal edge of each said barrier cuff section; and

closing means for securing at least a portion of said barrier cuff section juxtaposed said first end edge to the absorbent article inboard of said proximal edge;

said front ear flap sections being separably joined to said barrier cuff sections, wherein said distal edges of said ear flap sections may be separated from said barrier cuff section when the absorbent article is fitted to a wearer such that said distal edges of said front ear flap sections form said longitudinal edges in said front waist region;

said distal edges being unsecured to any underlying structure of the absorbent article in said rear waist region such that said distal edges form said longitudinal edges in said rear waist region; and

said distal edge of said barrier cuff section being secured laterally inboard of said proximal edge in said crotch region such that said second end edges of said side panels located in said rear waist region are inverted relative to said first end edges to form an inflected barrier cuff that stands up in said crotch region when the absorbent article is fitted to said wearer.

8. The absorbent article of claim 7 additionally comprising an ear flap joined to and extending outwardly from each said side panel in the rear waist region.

9. The absorbent article of claim 8 wherein said ear flaps additionally comprise a fastening means for securing the absorbent article about the waist of the wearer.

10. The absorbent article of claim 7 wherein said ear flap is permanently joined in said front waist region to form a pant.

11. The absorbent article of claim 8 wherein said ear flaps comprise a stretch laminate comprising a layer of elastomeric film sandwiched between two layers of nonwoven fabric.

12. The absorbent article of claim 7 wherein said side panels are z-folded in at least said barrier cuff section.
