Description

TECHNICAL FIELD

[0001] The utility model relates to temperature label technical field especially relates to a disposable temperature label. BACKGROUND

[0002] In modern logistics, pharmaceutical transportation and industrial production, temperature monitoring is an important link to ensure product quality and safety. Especially in cold chain transportation (such as vaccines, fresh food) and precision equipment temperature control (such as electronic components storage) and other application scenarios, temperature abnormalities may cause product deterioration, equipment failure, and even safety accidents. Therefore, the market demand for disposable temperature labels is increasing. Such labels can detect temperature changes in real time and provide irreversible color-changing visual feedback when the temperature exceeds the set range, ensuring that users can quickly identify abnormal conditions and take appropriate measures.

[0003] Currently, disposable temperature labels on the market usually use heat-sensitive color-changing materials or fuse-type temperature sensing elements to achieve temperature detection. These labels are mainly composed of a substrate layer, a temperature sensing material layer and a protective layer. The substrate layer is used for fixation and support, the temperature sensing material layer contains color-changing pigments or melting point control materials, and the protective layer is used to prevent external factors from interfering. For example, some labels use reversible color-changing materials (such as liquid crystals or thermochromic dyes), which can react in color when the temperature changes, but when the temperature returns to normal, the color will also return. In addition, there are some fuse-type temperature indicators that melt internally when the temperature exceeds the set threshold, causing irreversible changes to provide over-temperature alarms. However, these existing temperature labels still have certain limitations.

[0004] Due to the uneven distribution of temperature sensing materials in traditional temperature labels, some areas may be slow to respond to temperature changes, and even after the temperature reaches the set threshold, some areas may still not change color. In addition, existing technologies lack optimization in heat conduction, which may result in longer response times for the labels and inability to accurately indicate temperature abnormalities in a short period of time. This may pose a serious safety hazard for application scenarios that require rapid identification of temperature changes (such as vaccine cold chain monitoring or precision electronic component storage). Therefore, there is an urgent need for a disposable temperature label that can improve temperature sensing uniformity, optimize heat conduction paths and quickly respond to temperature overruns to meet higher standards for temperature monitoring.
