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 1):
A dosing device for dispensing doses of liquid from a container, the device defining an outlet passage with a front discharge opening and having a control chamber component defining a control chamber behind the front discharge opening, a flow path leading from past or around the control chamber component to the outlet passage by way of one or more flow openings adjacent the front of the control chamber, the control chamber component having one or more control openings to admit a restricted flow of liquid into the control chamber from a container for said liquid on which the device is provided in use, and an obturator in the control chamber which is movable in the control chamber to a blocking position where it blocks the outlet passage to terminate a dose;\n wherein the outlet passage has a tortuous flow-restricting formation.
