  Various methods are known as inspection methods for poor welding of heat seal portions in containers and packaging bags.

  For example, as a conventional device, there is a heat seal portion inspection device that subtracts a measurement thermal image obtained by imaging with an infrared imaging device and a basic thermal image, and outputs an abnormal alarm signal compared with a predetermined threshold value. It has been proposed (see, for example, Patent Document 1).

  In addition, as another conventional inspection method, from the shadow of the contents in the package obtained by irradiating near infrared light with a wavelength of 800 to 1000 nm on the back of the package in which the contents having fluidity are sealed and packaged There has been proposed a method for inspecting a package, which is characterized by detecting whether the seal of the package is good or / and excess or deficiency of contents (for example, see Patent Document 2).
