摘要 |
A fluid spray dispenser (2) having a fluid reservoir (20) for holding a fluid to be dispensed, a spray head (23) for dispensing the fluid and a porous medium (24) through which the fluid passes from the reservoir (20) to the spray head (23). The porous medium (24) has an effective pore size and/or permeability that decreases towards the spray head (23). Means and methods of creating the pore size and/or permeability gradients are discussed.
