ABSTRACT:
The mixing bucket and integral mold (10) has frustoconical walls (12), a bottom wall (14), a bottom rim (32) and top rim (24). A lid (16) closes and seals the bucket. A bail (28) is provided for lifting and carrying the bucket. A flange (38) that is integral with the bottom wall (14) and inside the bottom rim (32) reinforces and supports the bottom wall and forms a mold cavity (36). Agitators (60) each of which has a base, an integral post (68) and agitation surfaces (72) are attached to the inside surface of the frustoconical walls (12) along two helixes (62,64). The agitation surfaces are shaped and oriented to agitate and mix material when the bucket is rolled on its side walls (12). The agitation surfaces can be shaped and oriented to merely divide the material being mixed, to move material toward the lid (16), to move material toward the bottom wall (14), to move material radially inward toward the central axis (18) or to move material radially outward toward the side walls (12). The agitators (60) are axially spaced along the helixes (62,64) to reduce the torque required to rotate the bucket on its side walls (12). The lid (16) forms a cup that can be employed to measure material to be mixed.
