Abstract
A system for strengthening containers in a high-speed filling operation is disclosed. The system includes a supply tank having an intake line connected to a source of liquefied gas. A solenoid-driven injector apparatus positioned at an angle to the containers is connected via another intake line to the supply tank. A back pressure regulator controls the pressure within the supply tank and the injector apparatus. A liquid level control valve within the supply tank prevents liquefied gas from entering the back pressure regulator. Upon sensing the presence of a container, a sensor actuates a solenoid which opens an injector valve, allowing liquefied gas within a chamber to forcibly flow through an outflow line into the container. The solenoid is then deactivated, closing the injector valve and blocking the liquefied gas within the chamber from entering the outflow line. The injector apparatus also includes a heater positioned adjacent to the outflow line and an adjustment device for the injector valve.
