Cylindrical

Sam, a rhesus monkey, was one of the most well known monkeys of the space program. His name was an acronym for the U.S. Air Force School of Aviation Medicine at Brooks Air Force Base, Texas. He was launched on December 4, 1959, housed in a cylindrical capsule within the Mercury spacecraft atop a Little Joe rocket in order to test the launch escape system (LES). Approximately one minute into the flight, travelling at a speed of 3685 mph, the Mercury capsule aborted from the Little Joe launch vehicle. After attaining an altitude of 51 miles, the spacecraft landed safely in the Atlantic Ocean. Sam was recovered, several hours later, with no ill effects from his journey.

Where rectangular storage containers make a mess of mismatched lids and sometimes unstackable shapes, the ordinary cylindrical deli cups used for food delivery are far superior.
