The invention provides mixing apparatus which has a container base and a container lid with the lid carrying mixing means extending through the lid with at one end a mixing element and at the other end a drive connection to a drive motor. When the drive is operated the mixing element mixes the contents of the container, usually when the container inverted. The lid has a rim portion with a circumferential slot and the top edge of the container is located into the slot when the lid is assembled with the container whereby to improve connection between the lid and the container during mixing. The lid within the rim portion carries the mixing means and, during mixing, the assembly is held to lock the assembly together.

1. A blending lid for a container, the blending lid comprising a body configured to be fitted over the open end of a container for sealing ingredients within the container, wherein the body has mounted thereon blending means arranged for a high speed rotation, the blending means extending through an opening in the lid and having, at one end, means for connection to a drive motor external to the lid and, at the other end, a blending element for blending contents of the container when the drive means is operated, wherein the blending lid is configured for stacking with other blending lids of the same type and configuration, one on top of another, when the blending means is mounted on the body, wherein the body includes an upper portion in which the opening is formed, and wherein the upper portion includes a recess which is annular to said opening. 2. A blending lid according to claim 1 wherein the body includes a lower portion which defines an annulus concentric with said opening. 3. A blending lid according to claim 2 wherein the annulus is configured to align with the recess in the upper surface of a blending lid of the same kind and configuration when two of such blending lids are stacked one on top of another. 4. A blending lid according to claim 3 wherein lugs are provided in the recess, for engagement by the annulus of a blending lid of the same kind and configuration when two of such blending lids are stacked one on top of another. 5. A blending lid according to claim 2 wherein the annulus projects downwards so as to extend into a container when sealing fitted onto said container for a blending operation. 6. A blending lid according to claim 2 wherein an outer portion of said annulus defines a wall for abutment with or arrangement in close proximity with an internal surface of a container when sealing fitted onto said container for a blending operation. 7. A blending lid according to claim 6 wherein the blending element includes at least one blending blade, and wherein the annulus projects a distance greater downwardly than the distance than said at least one blending blade projects from the body. 8. A blending element according to claim 6 wherein the body includes a rim for fitting over the open end of a container for sealing ingredients in the container for a blending operation, wherein the rim defines an outer wall which projects downwardly by a distance which is less than the distance that the blending element projects from the body. 9. A blending lid according to claim 1 wherein the body has a planar upper portion and the blending element includes one or more blades configured to rest against or adjacent the planar upper portion of a blending lid of the same kind and configuration when two of such blending lids are stacked one on top of another. 10. A blending lid according to claim 1 wherein the lid is a single-use plastics component for disposal after a single blending operation. 11. A blending lid for a container, the blending lid comprising a body configured to be fitted over the open end of a container for sealing ingredients within the container, wherein the body has mounted thereon blending means arranged for a high speed rotation, the blending means extending through an opening in the lid and having, at one end, means for connection to a drive motor external to the lid and, at the other end, a blending element for blending contents of the container when the drive means is operated, wherein the blending lid is configured for stacking with other blending lids of the same type and configuration, one on top of another, when the blending means is mounted on the body, wherein the body has a central portion in the middle of which is the opening and an outer portion concentric with said opening, and a gap arranged between the central portion and the outer portion, when viewed from above, wherein the body includes a lower portion when viewed from the side, which is configured to locate in the gap between said central portion and said outer portion of a blending lid of the same kind and configuration when two of such blending lids are stacked one on top of another, and denesting lugs are provided in said gap, such that the lower portion of a first of said blending lids engages the lugs on a second of said blending lids, when said first blending lid is stacked on top of said second blending lid.
