a manner providing additional stability by making the pivot axes of the various legs converge together as the axes are extended downward additional stability may be achieved due to this non parallel angling of the pivot axes the ends of the legs like 613 that are distal from the container body will be lower when extended relative to their vertical position when retracted as shown in fig1 by the arrows 616 and 636 it is desirable to have the portions of the legs like 613 distal from their respective pivot axes flush or slightly above flush with the lowest portion 179 of the downwardly extending flange 177 that partially surrounds the bottom 170 of the container when the legs are extended it is desirable to have their distal portions like 613 below flush with the plane defined by the bottom 179 of the surrounding flange 177 the lower position of the distal ends 613 of the legs when extended helps to overcome any flex or slop in the leg pivots that might otherwise cause the container 100 to rock or wobble when resting on a flat horizontal surface the angling of the pivot axes may be achieved by angling the lower edge of a circular flange 612 that surrounds a pivot axis 611 on the container 100.
