  • The first rubber ice cube tray was invented by Lloyd Groff Copeman. One day in 1928, while walking through some woods collecting sap for maple syrup, Copeman noticed that slush and ice flaked off his rubber boots rather than adhering to them. Having recalled this incident over lunch with his patent attorney, he conducted experiments using rubber cups. Later, he set about designing and then patenting different types of tray: a metal tray with rubber separators, a metal tray with individual rubber cups, and a tray made completely of rubber.
  • The first flexible stainless steel, all-metal ice cube tray was created by Guy L. Tinkham in 1933. The tray bent sideways to remove the ice cubes. Several companies now offer pre-filled disposable ice trays for home freezing, which they claim provide better taste and reduced risk of contamination.
