A dispenser comprises a body having a storage chamber to substantially retain a selected dispensable material, a dilution chamber in communication with the storage chamber, the communication being such that fluid flow from the storage chamber to the dilution chamber is restricted, an outlet from the dilution chamber with a flow controlling device associated with the outlet, and an inlet to the dilution chamber to admit fluid from outside the body to the dilution chamber. The construction and arrangement of the dispenser is such that the selected dispensable material is retained in the dilution chamber in a diluted state.
