Abstract
Apparatus utilizing pressurized liquid for testing containers such as soft drink beverage bottles for the ability to withstand internal pressure and for the absence of leakage. The pressurized liquid is introduced into each bottle with a swirling motion through an annular passageway and air is expelled from the bottle through a vent tube positioned coaxially within the passageway. The outer wall of the annular passageway is formed by a resilient sleeve which is compressed radially and extended axially by the pressurized liquid to provide a tight seal with the bottle. Pressure within the bottle is monitored by a sensing member which is displaced by the pressurized liquid and actuates a pivotally mounted lever arm which provides an amplified movement and corresponding to the displacement of the sensing member. In the disclosed embodiment, the apparatus is mounted on a rotary turret, and the introduction of the pressurized liquid and the expulsion of air are controlled by valves which are actuated automatically as the turret rotates between different positions.
