Fluid feed system improvements

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 a pathway (25) or pathways located substantially adjacent the spray head (23) for the removal of air ingested into the porous medium (24) during spraying.

1. A fluid spray dispenser comprising:
a fluid reservoir for, in use, holding fluid to be dispensed; a spray head for dispensing the fluid, the spray head including a piezoelectric actuator and a perforate membrane; and a porous medium extending from the reservoir to the spray head, through which, in use, fluid passes from the reservoir to the spray head, the porous medium having a pathway located substantially adjacent the spray head, extending from the spray head, or from a point close behind the spray head, to an edge of the porous medium within the reservoir, for the removal of air ingested into the porous medium.
