Abstract
Absorbent cores comprising a core wrap which comprises a liquid permeable substrate layer, the core containing from about 87% to about 100% of superabsorbent polymer and having a funnel-shaped swelling chamber. The area of the core is at least twice the area of the swelling chamber, and the core contains a water responsive immobilizing agent to immobilize the superabsorbent polymer prior to water insult. The funnel-shaped swelling chamber is a portion of the absorbent core containing superabsorbent polymer and delimited by continuous permanent seals. Two permanent continuous seals form first opposing funnel wall segments, wherein first opposing funnel wall segments collectively comprise a first chamber angle about 20° to about 120°, the first chamber angle being the sum of angles formed by each first opposing wall segment with respect to the longitudinal axis.
