A dispenser having a hollow body to receive a flowable material. The body is generally cylindrical but tapers into an extension of narrower cross-section. There is an outlet at the distal end of the extension. 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 tapers into a conical extension of the spiral to extend into the extension of the body to a point adjacent the passageway. At least that part of the conveyor within the extension is a flexible resilient coil in contact with the interior of the extension. In the preferred embodiment, the dispenser is a toothbrush with bristles formed on the exterior of the extension and the outlet communicating with the extension and the bristles. There are various ways in which one handed operations of the device can be achieved.
