ABSTRACT:
A dispenser having a hollow body to receive a flowable material. The body is generally conical and has a wider end and a narrower end. There is an outlet at the narrower end. A spiral conveyor within the hollow body is able to rotate relative to the body. Rotation of the spiral conveys material received in the body through the outlet. The spiral conveyor is generally conical and extends into a point adjacent the passageway. At least that part of the conveyor within the extension is a flexible resilient coil in contact with, or close to, the interior of the body adjacent the bristles. In the preferred embodiment, the dispenser is a toothbrush with bristles formed on the narrower end of the body and the outlet communicating with the bristles. There are various ways in which one handed operation of the dispenser can be achieved.
