A dispensing device (10) for discharging a liquid or pasty product from a container (25) comprises a valve housing (11) containing a generally cylindrical passage (28) which, by means of two non-return flap valves (29), is divided into three successive portions. The device (10) also comprises a pressure means (19) affixed to an outer peripheral portion (16) of the valve housing (11) and arranged to communicate with the valve chamber (28c) through an opening (38), and a connecting piece (23) by which the device (10) may be mounted on a neck portion (24) of the container (25), and which is itself mounted on a second portion (22) of the valve housing (11) located diametrically opposite to the first-mentioned portion (16). The inlet duct (34) extends through said second outer peripheral portion (22) in a direction substantially perpendicular to passage (28) and terminates in an inlet opening (35) in the peripheral wall of said inlet portion (28a) which, at its end remote from valve chamber (28c), is closed by an end wall of the valve housing (11). <IMAGE> |
