Abstract
The invention relates to an apparatus for dispensing a restricted amount of powdered material, comprising a repository (2) for powdered material (4), an outlet (12), and a conduit (3). The apparatus defines an airway arranged to enable air to be drawn through the resting powdered material in the repository, thereby entraining the powdered material in the airflow and drawing the air and entrained powdered material through the conduit. The air and entrained powdered material is thereafter expelled out of the outlet. Additionally, the invention relates to a dip tube (3) for use in apparatus for dispensing a powdered material.
