ABSTRACT:
An apparatus for pressure testing a can body. The apparatus includes a housing having a pivotable cover and an empty can with the lid attached is placed in a cradle in the housing. As the cover is moved to the closed position, a hollow needle, operably connected to the cover, is automatically inserted through the wall of the can body. On locking of the cover in the closed position, an electric circuit can be established to introduce gas under pressure through the needle into the can body. A readout of the pressure required to bulge the can body is given, thereby indicating whether the can body meets manufacturing specifications.
