Abstract
A device (1) for dispensing a volatile substance and simultaneously or sequentially dispensing a soluble substance comprising a structure (2, 3, 4) floatable on a liquid (L). The structure includes a first chamber (5) adapted to receive a filling of a first ingredient (A) adapted to release and diffuse a volatile substance, such as a fragrance, as a result of being contacted with the liquid on which the structure is floated. The structure (1) further includes a second chamber (6) adapted to receive a second ingredient, such as a spa product to be dissolved into the liquid. Floating the device (1) on a liquid such as bath water causes the liquid to contact the first (A) and second (B) ingredients, whereby the volatile substance is released from the first ingredient (A) preferably in the form of a vapour or steam, while the second ingredient (B) is dissolved into the liquid. A preferred application is as a bathing implement or a product for toilet hygiene.
