Abstract: A readily disassemblable gun for dispensing multiple fluidic components to a mixer includes a handle having an upper barrel. A head asembly is detachably connected to a rear end of the barrel. The head assembly extends flexible, fluid transporting tubes to a forward portion of the barrel and a detachable cap is secured to the forward end for defining an initial mixing chamber between the extended ends of the tubes and a conduit extending from the cap. Fluid components to be mixed are introduced from a supply source through individual tube communicating passages in the head assembly through the tubes to the initial mixing chamber. After initial mixing, the fluidic components are dispensed into an elongate mixer for additional mixing and ultimate discharge. A trigger lever is mounted on the handle and includes a member which normally deforms the tubes for preventing flow of fluidic components therethrough and into the initial mixing chamber.

Abstract: A fluidic mixer for commingling fluidic materials including a conduit having a first end and a second end which loosely receives an elongate spiral rod. The spiral rod is formed with a core extending axially and substantially the length of the rod to define a closed center. Multiple helical flights are integrally joined to the core and have peripheral diameters dimensioned less than the inside diameter of the conduit. Notches are provided in alternate peripheral edges of the helical flights so that fluidic materials introduced in the conduit may travel in a spiral path defined by the helical flights, a path between the peripheral diameter and the inside conduit diameter and a path across the notches to thereby effect continuous and complete commingling of the fluidic materials.
