The present disclosure relates to a rotary mixing device that is easy to produce, assemble, use and dispose of. The device comprises a shaft, and at least one mixing member. The shaft and mixing member are formed of the same composite material and are produced by molding the components in essentially a single plane. Moreover, the runners that provide the liquid polymer material to form the components of the rotary mixing device also serve as holding elements. Consequently, a one-piece, single shot molded unit is produced containing the components and the holding elements.

What is claimed is: 1. A kit for mixing which comprises a shaft, a first mixing member, and a second mixing member disposed in a single plane: the shaft having: a first portion with a first cross-sectional shape and a second portion with a second cross-sectional shape, an end of the first portion including a first radially extending flange and an axially extending protrusion having a circular dome, and the first portion further including a second radially extending flange spaced axially from the first radially extending flange, wherein the second flange includes a base with a cross-sectional shape, a neck extending axially from the base, and a lip extending radially from an end of the neck; the first mixing member including: a first boss extending axially from a first surface of the first mixing member, the first boss including a first aperture, the first aperture adapted to receive the axially extending protrusion and the circular dome, and including a first inward extending shelf dimensioned to prevent axial movement of the shaft, a second boss extending axially from a second surface of the first mixing member, the second boss including a second aperture, the second aperture adapted to receive the first radially extending flange and the first portion of the shaft so as to prevent the first mixing member from rotating relative to the first portion of the shaft; a rim extending circumferentially around the two bosses, and a plurality of blades radially extending between the two bosses and said rim, wherein a trailing edge of at least one of the plurality of blades extends below the rim; the second mixing member including: a first boss extending axially from a first surface of the second mixing member, the first boss including a first aperture adapted to receive the base of the second radially extending flange so as to prevent the second mixing member from rotating relative to the first portion of the shaft, a second boss extending axially from a second surface of the second mixing member, the second boss including a second aperture, the second aperture adapted to receive the neck and the lip of the second radially extending flange, and including a second inward extending shelf adjacent an end of the second boss dimensioned to prevent axial movement of the shaft, a rim extending circumferentially around the two bosses, and a plurality of blades radially extending between the two bosses and said rim, wherein a trailing edge of at least one of the plurality of blades extends below the rim. 2. The kit of claim 1, further comprising a packaging member disposed in the single plane to which the shaft, first mixing member, and second mixing member are releasably secured. 3. The kit of claim 1, wherein the first cross-sectional shape of the first portion of the shaft is selected from the group consisting of a circle, a hexagon, a square, a cross, a rectangle, and a triangle. 4. The kit of claim 1, wherein the first cross-sectional shape of the first portion of the shaft is a cross. 5. The kit of claim 1, wherein the second cross-sectional shape of the second portion of the shaft is a hexagon. 6. The kit of claim 1, wherein the rim of the first mixing member and the rim of the second mixing member each define a shape, the shape being independently selected from the group consisting of a circle, a hexagon, a square, a rectangle, and a triangle. 7. The kit of claim 1, wherein the first radially extending flange has a cross-sectional shape that is different from the cross-sectional shape of the base of the second radially extending flange.
