Abstract
Abstract A mixing system for mixing and dispensing viscous material comprising a mixer, cartridge assembly, and dispenser. This timesaving mixing and dispensing system utilizes a self-contained cartridge assembly that can be transferred directly from the mixer to the dispenser without exposing the reactive materials to the external environment. The cartridge assembly includes a cup having a nipple where a nozzle may be attached for dispensing, a plunger, a cap for the cup, and a removable seal over the opening of the dispensing nipple.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
192 words
A mixing system for mixing and dispensing material comprising: a mixer having a housing, an arm rotatably supported by the housing, wherein the arm is constructed and arranged to rotate about a first axis of rotation, and a basket constructed and arranged to rotate about a second axis of rotation in the opposite direction while the arm is rotating: a cartridge assembly removably received by the basket comprising: a cup having a mixing chamber that receives the material to be mixed, a first opening at one end through which material is introduced into the mixing chamber, and a second opening at another end that extends through a nipple on the exterior surface of the mixing chamber through which the material is urged out of the mixing chamber after mixing is completed; and, a dispenser having a frame constructed and arranged to receive the cartridge assembly after the cartridge assembly is removed from the basket, a plunger that is received in the mixing chamber, and a piston disposed in the mixing chamber that communicates with the plunger to urge the material from the mixing chamber out of a nozzle attached to the nipple.
