Abstract
The invention concerns a device comprising a flask ( ) with variable internal volume having a rigid neck ( ) wherein is arranged the body ( ) of a dispensing head ( ) ending in a conduit ( ) discharging the liquid and containing a microporous pad ( ) for generating a head loss regulating the liquid flow pushed therethrough into a distribution chamber ( ) communicating with said conduit. The pad is advantageously made of a material inert with respect to the liquid and combined with an antibacterial filtering element ( ) preventing outside air from entering the flask. It evenly occupies the body ( ) over the whole cross-section of the liquid passage.
