Creative Ice Cubes In A Tray

Recent demand for premium, safe drink ice has created a new niche market for disposable ice trays which can be cost- effectively transported or stored at room temperature, whilst protecting the consumer from contaminants such as fecal matter, E. Coli or fertilizer residue commonly found in mis-handled ice cube trays and un-safe water supplies.
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.
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.
