Claim Text:
1. An item having liquid storage and/or discharge properties, comprising: a liquid-permeable proximal structure which is proximal with respect to a liquid emission zone, comprising a material capable of swelling in the presence of a liquid, a distal structure which is distal with respect to the liquid emission zone, capable of draining the liquid, a hydrophobic and nonabsorbent insert structure extending between the distal and proximal structures, and being capable of locally limiting, when said material is not swollen, the exchange of liquid between the distal and proximal structures by maintaining a gap between these structures, and of allowing a local expansion of the proximal structure in at least one zone where said material is swollen in response to coming into contact with the liquid, this expansion causing the proximal structure and the distal structure to move closer together locally and the transfer of said liquid from this zone of the proximal structure having undergone expansion to the distal structure.
