Claim:
An apparatus for mixing two or more fluid substances, the apparatus comprising: (a) an elongate primary chamber configured for containing a first substance, the primary chamber including a primary chamber dispensing end and a primary chamber non-dispensing end; (b) an elongate secondary chamber substantially aligned longitudinally with and attached to the primary chamber, the secondary chamber configured for containing a second substance, the secondary chamber including a secondary chamber dispensing end and a secondary chamber non-dispensing end wherein the secondary chamber non-dispensing end is proximate the primary chamber dispensing end; (c) a movable back plug configured for longitudinal movement along the primary chamber, wherein such longitudinal movement toward the primary chamber dispensing end causes at least a portion of the first substance to exit through the primary chamber dispensing end and at least a portion of the second substance to exit through the primary chamber dispensing end; and (d) a dispensing tip attached to the primary chamber dispensing end, the dispensing tip including a mixing chamber that, when the back plug is moved toward the primary chamber dispensing end, causes substantial mixing of the first substance with the second substance.
