APPARATUS AND METHOD FOR MIXING AND DISPENSING COMPONENTS OF A COMPOSITION

摘要

A cartridge assembly (1) used with a conventional caulking gun for mixing and dispensing components of a material. The cartridge assembly (1) includes a component carrying body that has a plurality of separate component reservoirs and a component flow directing housing at a forward end of the reservoirs. A mixing unit (60) extends between the component flow directing housing and a discharge nozzle (8) secured to the front end (3) of the carrying body. The mixing unit (60) mixes the components and delivers them to the discharge nozzle (8). The mixing unit (60) includes a plurality of mixing cylinders (89) that each have a longitudinal axis that extends substantially parallel to the longitudinal axis of the component carrying body. The mixing cylinders (89) and guiding channels (88) that extend between them from at least a portion of a component mixing path. The mixing cylinders (89) can each include one or more mixing elements. (140)
