<p>A dispenser for materials comprising a chamber (7) of known volume rotatably mounted on a lid of a container (1). Apertures (9, 6) in the lid and floor of the chamber (7) are aligned to allow material to pass from the container (1) to the chamber (7). The chamber (7) is rotated relative to the lid thereby misaligning the apertures (9, 6) and isolating the chamber (7) from the container (1). The known volume of material may then be dispensed from the chamber (7) through a dispensing aperture. A variable volume dispensing chamber is also disclosed.</p> |
