Abstract
A fluid delivery apparatus includes a housing having an open end and an interior surface. The interior of the housing defines a cavity within the housing. The cavity, in combination with a piston-like member, defines a reservoir for containing a fluid (e.g. such as an aromatic or other solvent or a solvent in which has been dissolved an aromatic substance). The piston has a port, and fits in piston-like arrangement within a cylinder contained within the housing. The piston moves within the housing, and movement of the piston acts to displace fluid from the port upon contraction of the reservoir (e.g. when the annular piston is driven into the device). Preferably, a fluid tight membrane covers the housing's open end. The apparatus also preferably further includes a conduit to transport fluid from the housing of the reservoir. The conduit has, on a first end, an exterior circumference sized and shaped to interact with the port of the annular member. On the second end of the conduit is preferably associated a sponge, wick or equivalent fragrance dispenser.
