Patent ID: 8890087

Claim:
A purification apparatus, comprising an elongate UV source and a conduit for water, or another fluid, to be purified, the conduit being formed of a UV transmissive material, wherein the conduit has an inlet and an outlet through which the purified fluid is dispensed, and is positioned so that part of it is wrapped around at least part of the UV source thereby to sterilise water or fluid within the conduit, further comprising reflective means for causing UV radiation to be reflected onto one or more parts of the conduit which extends beyond the part which is wrapped around the UV source, wherein the reflective means comprises a cap having a generally wedge shaped internal surface adapted to reflect UV radiation to an outermost end of the outlet which is not wrapped around the UV source and which is spaced a distance radially outward from the wrapped portion of the conduit, wherein the substantially wedge shaped reflective internal surface of the cap is tapered towards the outlet of the conduit.
