ABSTRACT:
A portable device for mixing two materials for discharge from a nozzle characterized by a separate container for each of the two materials with each container having means to discharge the contents of the container under pressure through a discharge tube, a mixing tube of flexible material having a discharge end and an inlet end with a mixing element received in the mixing tube and extending between the ends, a nozzle attached to the discharge end, and coupling means attached to the inlet end for connecting the discharge tubes of the containers thereto. The mixing element may take the form of a helically twisted strip member which may have projections extending from opposite edges thereof or may have one or more rows of perforation to form helical extending element spaced apart by a row of perforations and interconnected by bars extending between adjacent perforations. In another embodiment of the invention, the mixing member is a helical coil of wire with the coil either having a constant outer diameter or a varying outer diameter. In each case, the coaction of the mixing element plus the bending or curving of the flexible mixing tube, which bending or curving occurs during positioning of the nozzle coact to ensure a thorough mixing of the separately introduced materials prior to discharge from the nozzle.
