Aluminium bottle
An aluminum bottle is a bottle made of aluminum (or aluminium, in British English). In some countries, it is also referred to as a bottlecan. It is a bottle made entirely of aluminium that holds beer, soft drinks, wine, and other liquids.
History and overview
The aluminium beverage bottle made via the impact extrusion process was introduced to the North American beverage market in the fall of 2001 as an alternative to plastic bottles by Coca-Cola under the Powerade brand (Psych and Raize) at the National Association of Convenience Stores Show.
“Cooler longer” claim
A study conducted by engineering science students at Loyola College in Maryland suggested that the liquid content of aluminium bottles stays slightly colder than the liquid content of glass bottles when allowed to warm at room temperature.[1] These results were not corroborated by a 2005 study at Bucknell University, which found that “the fluid in the aluminium bottle cools much faster than the glass bottle, and once removed from a cold source and exposed to room temperature, the glass bottle remained cooler longer than the aluminium bottle.”[2] This conclusion is consistent with the fact that the bulk thermal conductivity of aluminium (237 W/(m·K)) is significantly higher than that of glass (1.1 W/(m·K)), as well as the fact that aluminium bottles are significantly thinner than glass.
