Abstract (en)
[origin: EP1387014A2] The dispenser comprises a closed bottle (11) containing active substance (R) in the liquid state, and a support means (50) for supporting said bottle (11). According to the invention there are provided a collection tray (15) supported by the support means and collecting water from the flushing flow in such a manner as to increase the water level in its interior, and a half-siphon (20) with an inlet (23) which draws water from the collection tray (15), and an outlet (24) positioned at a lower level than the inlet (23), to discharge water to the outside of the collection tray (15). Said half-siphon (20), on its action being triggered by the water level in the tray (15), draws water from the tray (15). The bottom of the interior of the bottle (11) communicates with the outside via a sized passage (26, 28, 32) able, when under static conditions, to prevent the active substance leaving through it; in addition, the suction side of the half-siphon (20) is connected to the interior of the bottle (11) via said sized passage (26, 28, 32) to draw a gauged quantity of active substance. <IMAGE>
