APPARATUS TO ENABLE METERED DISPENSING OF VISCOUS SUBSTANCE AND A DISPENSER INCLUDING THE APPARATUS.

摘要

An apparatus (100) to enable metered dispensing of a viscous substance comprises a first receptacle (5) defining a first path (6a), a second receptacle (3) enclosing said first receptacle and defining a second path (8). The second receptacle (3) is adapted to move away from the first receptacle to define a collection area for collection of a metered quantity of the substance and move towards the first receptacle for dispensing of the metered quantity. An actuator (2) is connected to said first and second receptacles to control said first path and said second path, such that in a natural state of the actuator, the first path is open and the second path is closed to allow flow of substance to the collection area and in an actuated state, the first path is closed and the second path is open to allow dispensing of the substance via the second path.
