<p>A diffuser (1) comprises a base portion (2) and a lid portion (3). The diffuser is adapted to allow emanation of vapour from a burning block of resin and contains a block receiving portion (40) raised up from a surface (41) of the base portion. The block receiving portion (40) comprises one or more grooves formed in a surface of the portion (40) and extended below the surface of the portion (40). The base portion further comprises apertures (43) forming channels extending from within the base portion to an outer surface of the base portion. The lid portion (3) is substantially pyramidal in shape and has an apex (5) at an end remote from the base portion. The lid portion (3) further comprises apertures (4) positioned towards the apex (5). In use, a burning cone of resin impregnated with fragrance is placed in the block receiving portion (40) and the lid portion is placed over the cone. The apertures (4 and 43) together with the grooves (42) serve to optimise the air flow within the diffuser optimising emanation of the fragrance from the cone.</p> |
