Motionless mixer tube for resin dispensing equipment

In combination, a discharge nozzle of a dispensing device which meters and dispenses at least two separate liquid materials streams from a pair of end openings formed in said nozzle, and a mixer tube mounted on said discharge nozzle;

• said mixer tube including an elongated housing formed with a hollow internal cylindrical bore extending therethrough having inlet and outlet ends;
• a female luer lock provided at the inlet end of the housing and having an inlet socket for removably securing the discharge nozzle of a dispensing device therein;
• a male luer lock provided at the outlet end of the housing and having an outlet nozzle;
• a dispensing needle formed with a hollow bore and having inlet and outlet ends removably mounted on the outlet end of the housing by the male luer lock, said inlet end of the dispensing needle being immediately adjacent the outlet end of the outlet nozzle of the male luer lock;
• and a helical motionless mixing element mounted within the bore of the housing and extending from and adjacent to an outlet end of the inlet socket of the female luer lock and adjacent to the outlet end of the outlet nozzle of the male luer lock.

A mixer tube adapted to be mounted on a tapered discharge nozzle of a dispensing device for mixing and dispensing at least a pair of liquid materials, said tube including:

• an elongated housing formed with a hollow internal cylindrical bore extending therethrough having inlet and outlet ends, said inlet end having a tapered inlet socket adapted to receive a tapered nozzle of a dispensing device therein, and having a tapered discharge nozzle at the outlet end;
• first attachment means on the inlet end of the housing for removably securing the housing on a discharge nozzle of a dispensing device;
• a dispensing needle assembly having a tapered interior;
• second attachment means on the outlet end of the housing for removably mounting the needle assembly on the outlet end of the housing, with the discharge nozzle being seated in and complementary to said tapered interior of the needle assembly;
• and
• a mixing element mounted within the bore of the housing and extending from and adjacent to an outlet end of the tapered inlet socket, and an outlet end of the tapered discharge nozzle.
