PURPOSE:To inspect heat-sealed conditions at a high inspection accuracy and speed without contact with containers. CONSTITUTION:In an inspection method of heat-sealed conditions of a container T, the temperature at each point along the seal-width direction of the heat- sealed part is detected by an infrared ray radiation superficial thermometer 20 without contact with the container. When the detected temperature distribution is different from a previously determined appropriate temperature distribution as a suitable article, more than a specified range, it is judged as an unacceptable sealing. |
