HOLE INSPECTION SYSTEM FOR HOLED CONTAINER

摘要

A hole inspection system for a holed container (1) for inspecting an outwardly opened hole (1a) formed in a flexible container (1) capable of properly inspecting for the size of the hole (1a) formed in the flexible holed container (1) by a simple configuration. The flexible container (1) is pressed from the outside to jet gas (A) in the container (1) from the hole (1a), and the jetting pressure of the gas jetted from the hole (1a) by pressing is detected. The detected value of the jetting pressure at a specified timing while the jetting pressure is raised is compared with an upper limit pressure value for the maximum size of the hole (1a) and a lower limit pressure value for the minimum size of the hole (1a) to determine the size of the hole (1a).
