Abstract: A fluidless bottle testing method and apparatus are disclosed. After being subjected to a squeeze test for side wall strength, bottles are moved to a bottle bottom tester which places the outer surfaces of the bottom and of the lower side wall of the bottle into tension. Bottles which would fail in service due to thin or weak walls, checks and scratches fail during the test and are thus removed prior to filling. Preferably the apparatus for performing the bottom test supports the bottle at a large bead on the neck or annularly at the lower portion of the side wall. A test rod is lowered (or the bottle is raised) into the mouth of the bottle and ultimately against the central bottom of the bottle, creating a flexure stress in the bottle bottom. The test facilitates rapid 100% bottle testing without the application of pneumatic or hydrostatic pressure to the interior of the bottle.
