Abstract

The application describes liquid dosing devices of the kind in which flow to a front discharge opening (44) of a container is blocked after a controlled delay by a sliding piston (3) movable in a control chamber (2) mounted in a container neck behind the discharge opening (44). Movement of the piston (3) is governed by restricted flow through control openings (28) at the back of the control chamber (2). Restoration of the piston (3) after a dosing operation is assisted by providing a dump valve at the rear of the control chamber. For simplicity and ease of construction, as well as effective sealing operation, the dump valve member is a ball (6) retained in a cage (5). Another proposal provides a one-way valve in the outlet path, obviating the dump valve and enabling rapid recovery after a dosing operation when used with a resiliently squeezable container.
