The dispenser comprises, for containing active substance (R) in the liquid state, a bottle (11) having an exit mouth (12) and supported by a support means (20) in an inverted position, with its mouth (12) facing downwards in a position subjected to the action of the flushing water flow. The support means (20) comprises, for containing the active substance, a reservoir (21) located in a position subjected to the action of the flushing water flow and arranged to receive the mouth (12) of the bottle, and a member (30) positioned in said containing reservoir (21) to close the mouth (12) of the bottle (11), an active substance descent passageway (35) enabling the active substance to descend in a gauged manner into the containing reservoir (21), and a ventilation passage which, when in use, connects the internal chamber of the bottle (11) to the ambient air; the containing reservoir (21) defines a volume for containing a quantity of active substance which closes said active substance descent passageway (35). According to the invention there is provided, discharging to the outside of the reservoir, a siphonic trap-means (40) having an inlet (42~) which draws liquid from the containing reservoir at a level (L2) below the level of the lower outlet section (P1) of the bottle mouth (12) and having a triggering level above the level of said lower section (P1), said containing reservoir (21) being enclosed within a collection region (50) arranged to temporarily retain the flushing water until a level is reached such as to trigger the action of the trap-means and then release the water into the W.C. bowl.

L'invention concerne un distributeur comportant un flacon (11) destiné à contenir la substance active liquide (R), présentant un orifice de sortie (12), porté par un support (20) en position inverse, l'orifice (12) étant dirigé vers le bas dans une position soumise à l'action de l'eau de chasse. Le support (20) comporte un réservoir (21) disposé dans une position soumise à l'action de l'eau de chasse, pouvant recevoir l'orifice (12) du flacon, et un élément (30) disposé dans le réservoir afin de fermer l'orifice (12), un passage descendant de substance active (35) permettant le passage dosé de la substance active en direction du réservoir (21), et un passage de ventilation reliant la chambre intérieure du flacon (11) à l'extérieur. Le réservoir (21) définit un volume destiné à contenir une certaine quantité de substance active, fermant ledit passage descendant (35). Selon l'invention, ledit distributeur comporte un élément de type siphon (40) ouvert vers l'extérieur du réservoir, comportant un orifice d'entrée (42') permettant l'entrée de liquide depuis le réservoir à un niveau (L2) situé en-dessous du niveau de la section de sortie inférieure (P1) de l'orifice (12), et présentant un niveau de déclenchement situé au-dessus du niveau de ladite section (P1). Ledit réservoir (11) est fermé par l'intermédiaire d'une zone de retenue (50) conçue pour retenir temporairement l'eau de chasse jusqu'à ce qu'un certain niveau soit atteint de manière à déclencher l'action de l'élément de type siphon et à évacuer l'eau dans la cuvette.
