Abstract
Apparatus for testing bottles to determine whether they will withstand internal pressure as from a carbonated beverage, also for detecting flaws in crown of bottle which may result in leaks. Hydraulic pressure is applied internally by hydraulic fluid, usually water. Bottle is filled with low pressure water, then high pressure water is used to apply pressure. Bottle is held between a sealing chuck which contacts and seals crown and a bottom member bearing against bottom of bottle, thus simulating force applied to bottle during filling with beverage and capping. Means are provided to remove air displaced during filling with low pressure water.
