Patent ID: 8485379

Claim:
An adaptor for holding a container having a predetermined width in a bucket of a mixing device, said adaptor having a central longitudinal axis and comprising: a pair of holding structures connected together for pivotal movement relative to each other along a pivot axis parallel to and spaced from the longitudinal axis, said movement being between an open position and a closed position, said holding structures each having top and bottom end surface and a plurality of interior surfaces defining an inner depression, said interior surfaces including first and second interior support surfaces disposed in planes perpendicular to the longitudinal axis, said first interior support surface being disposed at a different elevation than the second interior support surface; wherein when the holding structures are in the closed position, the inner depressions cooperate to define a cavity having a first region at least partially defined by the first interior support surface and a second region at least partially defined by the second interior support surface, said first region being adapted to hold the container when the container has a body with a circular cross-section and said second region being adapted to hold the container when the container has a substantially rectangular cross-section; wherein said inner depressions include a plurality of edges along axes parallel to and spaced from the longitudinal axis; wherein when the adaptor is holding the container and the holding structures are in the dosed position, the container is supported on the first interior support surfaces when the container has a circular cross-section, and is supported on the second interior support surfaces when the container has a body with a substantially rectangular cross-section; wherein the adaptor has a generally cylindrical shape; wherein the holding structures are each semi-cylindrical in shape and each include a semi-cylindrical outer surface and first and second inner surfaces disposed on opposing sides of the inner depression and the longitudinal axis, wherein in each holding structure, the outer surface is joined to the first inner surface at a first corner and is joined to the second inner surface at a second corner; wherein an outer depression is formed in the outer surface of each holding structure, toward the first corner, and wherein each outer depression is defined in part by an inwardly disposed longitudinal surface.
