Abstract
A method for inspecting a sealing property of a plastic container having contents. The container has a lid which is deflectable under a negative pressure developed in the container. The contents are charged in to the container so that a negative pressure is developed under a normal temperature or room temperature. The deflection of the lid is measured so as to detect the sealing property of the container.
