Abstract
The present invention relates to absorbent articles for retaining body fluids such as urine, menses, or fecal material. In particular, the absorbent article of the present invention comprises a liquid handling member that collapses at a pressure between 2756 Pascal (0.4 psi) and 3447 (0.5 psi) in order to reduce the likelihood of causing skin marking.
Claims6
An disposable absorbent article comprising
- a liquid pervious structured carrier,
- a liquid impervious backsheet at least partially peripherally joined to said structured carrier,
- a liquid storage structure positioned intermediate said structured carrier and said backsheet, and
- a liquid handling structure positioned intermediate said structured carrier and said liquid storage structure, said liquid handling structure having a caliper under a confining pressure of 689 Pascal (0.1 psi) of at least 0.5 mm, and having a resiliency of at least 50% after 30 seconds under an applied pressure of 1 Newton/cm2,
- wherein said liquid handling structure has a caliper under a confining pressure of 2756 Pascal (0.4 psi) of at least 80% of said liquid handling structure's caliper under a confining pressure of 689 Pascal and said liquid handling structure has a caliper response to a change in confining pressure from 689 Pascal to 2456 Pascal that is less than a caliper response to a change in confining pressure from 2456 Pascal to 3447 Pascal (0.5 psi) whereby said liquid handling structure has a caliper of at a confining pressure of 3447 Pascal that is less than 60% of said liquid handling structure's caliper under a confining pressure of 689 Pascal.
