Abstract
An instrument (1) for powderous or pasteous substances has a control unit (40) and a dispensing unit (50). The control unit is configured as a grip handle to be handheld. The dispensing unit is designed for removable seating in the holder device. A vertically movable shutter bolt (52) can open a discharge orifice (58). The control unit (40) has an actuator (20) directed at the shutter bolt, with a motor (21), a transmission (22), an actuator element (30) and a drive shaft (12), oriented vertically when operated. The drive shaft (12) can be engaged with the shutter bolt. Continuing and increased actuation of the actuator element moves the shutter bolt into an opening range where the shutter bolt opens up the discharge orifice to a variable, position-dependent extent, allowing the material to flow into a target vessel.
