The dispenser comprises a bottle ( 11 ) containing in its interior active substance (R) in the liquid state and having an exit mouth ( 12 ), and a support means ( 20 ) for supporting said bottle ( 11 ) in an inverted position, with its mouth ( 12 ) facing downwards, in a position subjected to the action of the flushing water flow. According to the invention, the support means ( 20 ) comprises: a closed transition chamber ( 30 ) positioned below the exit mouth ( 12 ) to contain and retain, for at least part of its volume, the active substance and, for closing the mouth ( 12 ), a member ( 21 ) which connects the mouth to the transition chamber ( 30 ) via a sized hole through which the active substance descends, said transition chamber ( 30 ) having an aperture ( 35 ) for the exit of the active substance from the chamber. There is also provided a substantially horizontal diffuser plate ( 25 ) positioned adjacent to said active substance exit aperture ( 35 ). Said exit aperture ( 35 ) is sized in relation to the physical-chemical characteristics of the active substance such that this occupies and closes the aperture ( 35 ) and also halts the discharge of the substance from the bottle interior, it outflowing therefrom only through a relatively short distance, said diffuser plate ( 25 ) being disposed in a position relative to the W.C. bowl such that the flushing water washes said exit aperture ( 35 ).
