- a tray having a bottom;
- a first set of a plurality of camming means spaced around a first circular locus on a lower portion of said container;
- and a second set of a plurality of camming means attached to the upper portion of the bottom of said tray and being spaced around a second circular locus, said first and second sets of camming means being adapted such that in at least one position of the container relative to the tray one of said sets of camming means can be telescoped within the other said set of camming means without any substantial wedging action between said sets of camming means, said first and second sets of camming means being further adapted such that upon twisting of the container relative to the tray the thus telescoped camming means slide one upon the other to cause a wedging action between said sets of camming means.
