Safety label for frozen food, has volume range, which is filled partially with fluid that has physical characteristic and is so designed that physical characteristic changes when predetermined threshold temperature exceeds for frozen food

摘要

The safety label (100) has a volume range (102), which is filled partially with a fluid (104), where an indicator element (106) is assigned to a section (108) of the volume range. The fluid has a physical characteristic and is designed such that the physical characteristic changes when a predetermined threshold temperature exceeds for frozen food, so that a quantity of the fluid irreversibly changes in the section of the volume range, as well as an externally detectable indicator characteristic of the indicator element is changed.
