<p>Methods and apparatus are provided for mixing and dispensing multi-component compositions. The preferred embodiment utilizes a syringe barrel (22) as a mixing chamber and for dispensing of the mixed components. A mixer element, preferably including a paddle member (32) and finger grip means (34) for rotating the paddle member (32), is provided for insertion into the syringe barrel (22) to effect the desired mixing. A scraper element (52) is used to scrape mixed components from the mixer element so as to retain the mixed components within the syringe barrel (22) upon removal of the paddle member (32) after mixing is completed. Mixing is preferably performed with the multiple components placed in side-by-side orientation within the syringe barrel (22) rather than one on top of another.</p> |
