Abstract
A delivery tip for flowable materials with bristles extending therefrom. The tip is a cannula with a tapered outlet and features a bristle bundle with a binding disk that interfaces with the cannula at some point within the cannula but has a smaller cross-section than the cannula at that point. The bristle bundle then extends out of the tapered outlet. The delivery tip is connected to a material reservoir with flowable material. When positive pressure is applied to the reservoir, material then will flow through the cannula, around the disk, into the bristles and out the outlet for distribution to a desired surface.
