SYSTEM AND METHOD FOR DELIVERING A LIQUID COMPOSITION INSIDE A TOILET BOWL

摘要

A system (1) for delivering a liquid composition (L) inside a toilet bowl (2) is described, which comprises : a) a container (3) of the active substance closed in a substantially air-tight manner and wherein said liquid composition (L) is subjected to a predetermined pressure, b) a supporting structure (4) for the container (3), c) hooking means (5) associated to the supporting structure (4) for supporting the container (3) and the supporting structure (4) inside the bowl (2), d) valve means (7) for delivering dosed amounts of said active substance comprising : - a valve body (16) wherein a metering chamber (24) of the liquid composition (L) is defined between a lower opening for delivering (8) the liquid composition (L) and an upper opening (44) for fluid communication with the air-tight closed container (3); a shutter (23) displaceable in the metering chamber (24) between said upper (44) and lower (8) openings; an opening device (14) operable at each flushing by the water introduced into the bowl (2) and cooperating with the shutter (23), the opening device (14) being provided with deflecting means (45) for directing part of the flushing water towards the delivering opening (8) of the liquid composition (L) and into the metering chamber (24). Advantageously, the system (1) according to the invention allows to deliver dosed and constant amounts of liquid composition (L) at each water flushing independently of both the amount of liquid composition (L) provided in the container (3) and of the frequency of the flushing operations.
