ABSTRACT:
A tester for testing the physical characteristics of bottles such as the degree of stretch of a plastic bottle and the pressure required for rupturing a glass bottle. The apparatus includes an elongated cylinder having a bore extending therethrough. A piston is threadably carried within the bore so that when the lower end of the cylinder is secured to the top portion of a bottle, the piston is in axial alignment with the bottle. Upon feeding the piston into the bottle filled with an incompressible fluid, pressure is exerted on the interior of the bottle stretching or exploding the bottle depending on the test being performed.
