METHOD OF INSPECTING SEALED CONTAINER AND METHOD OF PRODUCING SEALED CONTAINER PRODUCT THAT CONTAINS CONTENTS

摘要

[PROBLEMS] To provide a method of highly accurately inspecting a sealed section of a container body. The method is a method where not only an abnormality of the shape of the container body but also a foreign object-attributed abnormality of the sealed section of the container body can be inspected, and not a method where a visible light is irradiated to the sealed section of the container body and the reflected light is used for the inspection. [MEANS FOR SOLVING PROBLEMS] A method of inspecting a sealed section (2) of a container body (3) of a sealed container (5) composed of the container body (3) with the sealed section (2) surrounding an opening (1) and a lid member (4) for sealing the container body (3). An excitation light-emitting object excited and emits light by ultraviolet irradiation is used as the container body (3). Before the container body (3) is sealed by the lid member (4), ultraviolet (UV) is irradiated to the container body (3) to cause the excitation light-emitting object to emit excitation light, and the light exits from the sealing section (2) is observed.
