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.
