The very first portable ice box to be launched onto the market was attributed to Richard Laramy which application for a US patent was accepted by the US Patent Office on 24th February, 1951. This patent was granted on 22nd December 1953 and, although marketing these early coolers took a route all its own, Laramy of Joliet Illinois became the owner of the first US patent for the technology that encompassed all future insulated boxes. This is not to say that the concept behind the excluded boxes had not been long thought of and available on the market many years before. Richard Laramy, however, was the first person to apply for, and be granted, a US patent for this product.
The great convenience surrounding this great invention was popularized by the Coleman Company which early technology produced galvanized ice boxes which they released onto the US market the following year, in 1954. This company was later, in 1981, to purchase the rights to the Australian- introduced cooler which had been independently developed by a family owned company in Australia. It was the Coleman Company that popularized the use of plastic linings for use in cooler boxes of various sizes. The technology may have developed over the years, with new materials being introduced and new manufacturing techniques to improve the great convenience that is an integral feature of all cool boxes: their ability to keep their contents at least as cold as they would be if kept in a domestic refrigerator.
As the ice box has gained in popularity, many more companies are now manufacturing their own ice box models, each representing their own concept of their great convenience when used away from the domestic setting. You only have to surf the internet to find innumerable makes and models of cool boxes, available in a wide range of standards and prices, shapes and sizes. Nowadays, technology has revealed that increasing the thickness of the insulation improves the length of time that food will stay fresh and drinks will remain cold. These standards are now being widely adopted by the many manufacturers, all of which are increasing the thickness of the walls of their cool boxes as well as the thickness with which the lids are produced.
Ice boxes remain particularly popular with US households, partly due to the wide choice available, at prices that encompass many budgets. Cool boxes also continue to be popular due to their abilities to withstand both hot and cold temperatures, with the contents of these ice boxes capable to remain cold even when the ambient temperatures outside the ice box is particularly hot. Similarly, when outdoor temperatures become particularly low, many models of cool boxes have the capacity to keep food inside the ice box warm enough for you to pack hot soup and expect it to remain hot when you are ready to use it.
The great convenience of a modern ice box is large due to the quality of the insulation, incorporating the latest technology to enable contents to be kept hot or cold, depending on your requirements. Of course, there are other innovations that make these cool boxes popular. However, none of these innovations are completely exclusive to just one manufacturer. Nowadays, technology and new ideas are often tested by many manufacturers before they decide whether or not to incorporate these innovations into their new products.
