Microwave-heatable exercise putty in a container with temperature indicator

摘要

A microwave-heatable therapeutic exercise putty mass is packaged in a microwaveable container having at least one transparent wall. The putty mass within the container is in heat transfer proximity with transparent wall of the container. A thermochromic heat sensitive semiconductor material (strip, label or coating) is affixed to the transparent wall in intimate heat transfer contact with the putty mass. The thermochromatic material provides a visual first indication through the transparent wall when the putty mass has been microwave heated to a heat exercise therapy acceptable temperature range of about 40 to about 47 degrees C. and a visual second indication through the transparent wall when the putty mass has been microwave heated to a temperature range of about 54 to about 60 degrees C. or above which is non-acceptable for heat exercise therapy.
