Special label or imprint on baby bottles for the determination of the ideal drinking temperature by means of reversible hue change

摘要

Special label or special imprint on baby bottles for the determination of the ideal drinking temperature. For the determination of the ideal drinking temperature, a temperature measuring range is applied to baby bottles. This temperature measuring range can be printed directly on the baby bottle or on a plastic label or metal film label, which is subsequently stuck onto the baby bottle. The printing can also be carried out on a plastic roll material and then be sealed on or welded on to the baby bottle. The printing is carried out with a thermochromic colour on the basis of micro-encapsulated liquid crystals. So that an accurate drink temperature matching is possible, a colour control field is additionally imprinted in the colour into which the liquid crystals will change on attaining the drinking temperature.
