Abstract:
A dosing device is described, for dispensing doses of liquid from a container. It has an outlet passage with a front outlet tube ( 44 ) and a control chamber ( 2,29 ) positioned behind the front outlet tube. A flow path for dosed flow of liquid squeezed from the container leads in around the front of the control chamber ( 2,29 ) to the outlet tube ( 44 ), via flow openings ( 23 ). The control chamber ( 2 ) has control openings ( 28 ) to admit a restricted flow and time the fall of a blocking piston ( 3 ) to a blocking position where it blocks the outlet passage to terminate a dose. To improve uniformity of dosing, the outlet tube ( 44 ) has a tortuous flow-restricting formation ( 449 ) formed by a set of inward radial finger projections ( 49 ).

Claim (Index 10):
A dosing device according to  claim 9  in which the dump valve comprises a dump valve seat and a dump valve member which make a convergent guiding engagement with one another, the dump valve member entering the dump valve seat to make a seal in a closed condition of the dump valve.
