A tamperproof package comprising a container having a neck and an annular radial flange beneath the neck and a plastic closure removably interengaged with the neck. The closure has a top wall and a peripheral skirt. A plastic pilfer band interengages the skirt, such that when the closure is applied to the container, the band is flexed over and engages beneath annular flange on the neck of the container, and when the closure is thereafter removed from the container, the band is prevented from removal from the container and is thereby disengaged from the closure. In a modified form the plastic pilfer band includes an integral liner which is severed from the band and engages the top wall of the closure during assembly of the band to the closure.

Tamperproof package

Apparatus for testing pressurized sealed containers for leakage including a fluid filled tank for receiving the container to be tested. The tank is comprised of a transparent side wall, a bottom wall and a top wall. Means are provided for piercing the container to be tested. Means are further provided for attachment to the piercing means for providing communication between the interior of the container and a source of pressure fluid operable to pressurize the container being tested only when the top wall of the tank is in a closed position.

Pressure test fixture for pressurized containers

Apparatus and method for the assembly of a two component home canning closure. One popular type of home canning closure utilizes a relatively thin lid to seal a jar with a threaded band holding the lid down. The gasket portion of the lid is relatively fragile. In the assembly of the two components in a manufacturing process for shipment to the consumer, the lids are handled gasket upmost the minimize possible damage. At an assembly station, the lids are rotated 180.degree. to present the gasket downward in the band for protection during shipment and storage.
