Abstract
A paste dose dispenser is provided which incorporates a housing (1) through which passes a drive rod (3) connected to a plunger (4). A lever (14) is pivotally mounted on a pin (15) for movement towards a handle (2), such action causing a plate (9) to tilt and thus grip the rod (3) and drive the rod in a forward direction against the bias of a spring (11). The degree of movement of the lever (14) is determined by the position of the sliding dose adjuster (19) carrying steps (21) which will be engaged by a boss (20) carried by the lever (14). Ball and detent locating means (24) are provided to hold the dose adjusting plate (19) in each of the alternative positions. Fine adjustment of the degree of movement of the lever (14) can be effected by screwing the boss (20) into the handle (14) and securing it by a lock nut (29).
