ABSTRACT:
Rotary storage unit carries outward lugs. Support surface carries an oblong plastic ring surrounding lug area. Ring is supported adjacent ends of major diameter only. Ring and lugs are dimensioned to forcibly interengage adjacent minor diameter of the ring, distorting the ring. Ring is recessed at ends of minor diameter so that lugs snap into recesses when unit is moved into certain rotary position. This snap engagement serves as a catch for holding the unit in "closed" position.
