12. The combination defined in claim 1 , the body of the dispensing container being elongated along a central axis and configured to have a height-to-base ratio (HBR) between 0.75 and 1.5 at half volume and a greater HBR than the jar for the same total volume, when measured with the central axis of the dispensing container parallel to the longitudinal axis of the jar.

13. The combination defined in claim 1 , wherein the adapter is in contact with a bottom wall of the jar.

14. The combination defined in claim 13 , wherein the adapter is in contact with the inner wall of the jar.

15. A planetary mixer comprising a motor for subjecting a holder to superimposed rotation and revolution movements, the holder holding a jar containing a dispensing container secured to an adapter, the jar having a top, an inner wall and a bottom, the dispensing container having at least a body and a removable cap; and

the adapter having a central aperture through which a longitudinal axis of the jar passes when the adapter is positioned inside the jar, the central aperture being smaller than the removable cap of the dispensing container; wherein (i) the adapter is configured to maintain the dispensing container spaced from the inner wall of the jar and from the bottom of the jar; (ii) a gap is provided between the top of the jar and the cap of the dispensing container; (iii) a part of the cap of the dispensing container is further from the bottom of the jar than a part of the body of the dispensing container; (iv) the body of the dispensing container crosses the longitudinal axis of the jar; and (v) the dispensing container extends over more than half the diameter of the jar, and

wherein the inner wall of the jar is tapered and wherein the inner wall and the adapter are configured such that the distance between the adapter and the inner wall varies as the adapter extends further into the jar.

16. The planetary mixer defined in claim 15 , wherein the adapter is configured to clamp the dispensing container.

17. The planetary mixer defined in claim 16 , the body of the dispensing container being elongated along a central axis and configured to have a height-to-base ratio (HBR) between 0.75 and 1.5 at half volume and a greater HBR than the jar for the same total volume, when measured with the central axis of the dispensing container parallel to the longitudinal axis of the jar.

18. The planetary mixer defined in claim 17 , wherein to clamp onto the dispensing container, the adapter is configured to clamp onto the cap of the dispensing container.

19. A container assembly for use with a planetary mixer, comprising (i) a jar with an inner wall, (ii) an adapter in contact with the inner wall of the jar, the adapter including a central aperture, (iii) a dispensing container having at least a body and a removable cap, the central aperture being smaller than the removable cap of the dispensing container and (iv) a lid attachable to a rim of the jar,

wherein the adapter is configured to clamp onto the dispensing container,

wherein the inner wall of the jar is tapered and wherein the inner wall and the adapter are configured such that the distance between the adapter and the inner wall varies as the adapter extends further into the jar.

20. The container assembly defined in claim 19 , wherein the inner wall is tapered between a top of the jar and a bottom of the jar.

21. The container assembly defined in claim 19 , wherein the adapter is further configured to maintain the dispensing container spaced from the inner wall of the jar.
