Abstract
An assembly for mixing two different liquid components includes a container having two barrels, and an exit conduit detachably connected to the container. The exit conduit includes a static mixer along with a check valve located between the static mixer and an outlet of the exit conduit. The check valve prevents the dripping of mixed materials from the exit conduit between intended dispensing operations, and may be discarded along with the exit conduit after extended interruptions between dispensing operations.

A static mixing assembly comprising:
- a container having a first barrel with an exit port, and a second barrel with an exit port;
- a first piston movable in said first barrel and a second piston movable in said second barrel simultaneously with movement of said first piston, for ejection of materials from said first and second barrels through respective exit ports;
- and
- an exit conduit having an inlet end, an outlet, and means for detachably connecting said inlet end to said exit ports of said first and said second barrels, said conduit including a static mixer located between said inlet end and said outlet for mixing materials ejected from said first and said second barrels, said conduit including a check valve located between said static mixer and said outlet for substantially preventing drippage of mixed materials from said outlet after movement of said pistons has ceased, whereby said check valve may be discarded with said exit conduit once said exit conduit is detached from said exit ports.
