Abstract
A molded, disposable mixing device is disclosed for mixing and dispensing a two-part fluid compound. The device may consist of two mirror-image portions or structures, each being of semi-cylindrical shape and providing a tortuous path for shearing, folding, mixing and blending together the two fluids. Each of the two structures is provided with a male attachment lug, and a female detent for securing them together. Also, each structure has a semicircular, externally molded ridge for connecting it, for example, to a nozzle. The tortuous path may consist of two periodically intersecting paths, or else of a generally open passage provided with mixing blades or baffles disposed at regular or irregular intervals. The mixing may also be effected by a spirally folded mesh or spherical objects disposed in a single tubular structure.
