PROBLEM TO BE SOLVED: To provide an air leak inspection method capable of highly accurately detecting whether a pin hole exists in the inner bag of a delamination container.SOLUTION: In an air leak inspection method of a delamination container including a container body including a storage part storing a content and a mouth part discharging the content from the storage part, and having an outer shell and an inner bag, the outer shell includes an outside air introduction hole communicating an intermediate space between the outer shell and the inner bag with an external space of the container body. The air leak inspection method of the delamination container includes an air leak inspection step in which when air is injected from one of the mouth part and the outside air introduction hole, a flow rate of air leaked from the other one is measured.SELECTED DRAWING: Figure 1 |
