A sealed condition inspecting device comprising a support unit for supporting an element to be inspected for a sealed condition, a pair of electrodes in contact with the portion to be inspected of the element to be inspected and supported by the support unit, an electrical variable detecting unit for detecting an electrical variable in the portion to be inspected, and a sealed condition judging means for judging the acceptability of a sealed condition based on the electrical variable. In fact, since the acceptability of a sealed condition is judged based on an electrical variable in the portion, to be inspected, whether or not a defective sealed condition has occurred can be determined independently of the subjectivity of the operator, whereby a sealed condition can be inspected for a sealed condition without unpacking them, not only inspection work can be simplified but reliability in the quality of an element to be inspected can be improved.

Sealed condition inspection device

The object of the invention is to provide a container inspection method and a container inspection device which is not container quality inspection by individual and operator's empirical approach, not influenced by operator's skillfulness, can eliminate human error such as missing when recording and error in writing, not based on operator's subjective judgment, whose result is objective, and easily and statistically stores objective data. The container inspection method and container inspection device comprises an inspection for a container formed of a web-like packaging laminated material, which includes peeling flaps from the container wall by a pre-processing unit, cutting the container wall to prepare a sampled body by a sampled body preparing unit, inspecting seal quality by a seal quality unit, inspecting seal zone by an image processing unit, and inspecting damage on the seal zone by a seal damage inspection unit.
