    摘要: A housing (300) is provided with a thermochromic level indicator (308). The housing may be, for example, a beverage can or bottle. The housing has a wall presenting an interior space capable of retaining matter at a first level within the wall. The housing also has an opening or lid that may be opened to permit the matter to exit from within the wall or enter into the wall such that the matter assumes a second level (311). The wall supports a level indicator (308), which is formed of thermochromic ink. The thermochromic ink has a color transition temperature capable of acting as a level indicator by sensing temperature of the matter retained within the wall in an intended environment of use as the matter transitions between the first level and the second level. By way of example, the matter may be a beverage and the wall forms at least part of a beverage container.
