Abstract
A paste dispenser includes a housing which has two angularly spaced vanes which rotate about an axis. The two vanes and a contoured surface form a paste-receiving chamber. Paste is forced into the dispenser under pressure from a paste container such as a toothpaste tube. The paste fills the paste-receiving chamber, and continued pressure causes the contents of the paste-receiving chamber to be deposited at an opening where it can be claimed by a user.
