A device for expelling/containing a predetermined liquid. The device configured to be built into a liquid tank operable at low or zero gravity and comprising a unitary three-dimensional sponge structure. The sponge structure comprises a set of substantially wire-like elements that extend between a peripheral area of the sponge structure and an area for expelling/containing liquid. The wire-like elements are substantially oriented in the direction of flow of the fluid within the device. The wire-like elements are connected together by crosspieces and are arranged such that the capillary gradient is positive or zero in the direction of flow of the fluid from the peripheral area to the area for expelling/containing liquid.
