The present invention relates to an item (10) having liquid (L) storage and/or discharge properties, in particular a bandage, comprising: —a liquid-permeable proximal structure (20), consisting of a material capable of inflating in the presence of liquid (L), —a distal structure (30) capable of draining a liquid (L), —a hydrophobic and non-absorbent spacer structure (40) extending between the distal (30) and proximal (20) structures, and being capable of locally limiting, when said material is not inflated, the exchange of liquid between the distal and proximal structures by maintaining a gap between said structures, and of authorizing a local expansion of the proximal structure in at least one zone (P) where said material is inflated in response to coming into contact with a liquid, said expansion causing the proximal and distal structure to move together locally and the transfer of said liquid from the zone of the proximal structure (20) having undergone expansion to the distal structure (30).
