Document Type and Number:
WIPO Patent Application WO/2009/157092
Kind Code:
A1
Abstract:
An airtightness inspection technique of enabling an airtightness leakage place in a box body or the like, which has a simple structure and ensures the safety to be reliably found and identified at low cost. An airtightness inspection device comprises a smoke container (2) for holding dry ice (D), a water tank (3), an attachment hole (91) formed in a box body (K) in order to attach a steam movement controller (S), a water passage (4) for connecting the smoke container and the water tank, and a pump (5) for pressurizing the inside of the box body. The airtightness inspection device supplies water into the smoke container to allow the smoke from the dry ice and pneumatically pressurizes the inside of the box body or the like with the white smoke filled to leak the white smoke from the airtightness leakage place. The airtightness inspection device finds and identifies the airtightness leakage place by visually observing the leaked white smoke.
