A device for providing a relatively constant rate of dissolution of a solid article () within it has one or more opening () to allow the passage of water. There is a flow pathway between said one or more openings and the solid article, which flow pathway is obturated by a water-permeable packing (), through which water must pass, in entering or leaving the device.

A diffuser includes a base portion and a lid portion. The diffuser is adapted to allow emanation of vapor from a burning block of combustible material and contains a block receiving portion elevated from a surface of the base portion. The block receiving portion has one or more grooves formed in a top surface of the block receiving portion and extending below the top surface of the block receiving portion. The base portion further includes apertures forming channels extending from within the base portion to an outer surface of the base portion. The lid portion is preferably substantially pyramidal in shape and has an apex at an end remote from the base portion. The lid portion further includes apertures positioned towards the apex. In use, a burning block of combustible material, impregnated with fragrance, is placed on the block receiving portion, and the lid portion is placed over the block. The base and lid apertures, together with the grooves in the block receiving portion, serve to optimize the air flow within the diffuser, thus optimizing emanation of the fragrance from the block.
