Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
189 words
A disposable fluid mixing device comprising: a first and a second structure, said structures being mirror images of each other; each of said structures being substantially semi-cylindrical in form and forming a chamber with the other upon mating of said first and second structures, the chamber having an inlet end, an outlet end, a plurality of spherical objects, and a pair of wire mesh retainers adjacent the inlet and outlet ends, respectively, for retaining the objects within the chamber while permitting the flow of fluid therethrough; said chamber in conjunction with the plurality of spherical objects disposed in said chamber forming a tortuous fluid path for the mixing of fluids therein; a first semi-circular ridge molded on the outside of each of the structures to form a projection extending about the chamber adjacent the inlet end; a second semi-circular ridge molded on the outside of each of the structures adjacent the outlet end to cooperate with a selected member to be associated with the mixing device; and means for securing said structures to each other comprising a retainer ring for mounting adjacent the inlet end over the first ridges.
Claim 2
Dependent Claim
189 words
A disposable fluid mixing device comprising: a first and a second structure, said structures being mirror images of each other; each of said structures being substantially semi-cylindrical in form and forming a chamber with the other upon mating of said first and second structures, the chamber having an inlet end, an outlet end, a plurality of spherical objects, and a pair of wire mesh retainers adjacent the inlet and outlet ends, respectively, for retaining the objects within the chamber while permitting the flow of fluid therethrough; said chamber in conjunction with the plurality of spherical objects disposed in said chamber forming a tortuous fluid path for the mixing of fluids therein; a first semi-circular ridge molded on the outside of each of the structures to form a projection extending about the chamber adjacent the inlet end; a second semi-circular ridge molded on the outside of each of the structures adjacent the outlet end to cooperate with a selected member to be associated with the mixing device; and means for securing said structures to each other comprising a retainer ring for mounting adjacent the inlet end over the first ridges.
Claim 3
Dependent Claim
22 words
The mixing device of claim 1 wherein said second ridges mate to form a snap connection for attaching a fluid dispensing nozzle.
Claim 4
Dependent Claim
33 words
The mixing device of claim 1 wherein the wire mesh retainer adjacent the inlet end is recessed therefrom to permit the insertion of a fluid nozzle into the inlet end of the chamber.
