Abstract
A clamping system for a fluid injection gun and cartridge such as the type in which fluid foam precursors are fed to the cartridge to be mixed and distributed to make custom foam packaging. The clamping system comprises a valve that defines respective opened and closed positions, a clamp seat adjacent the valve for receiving an injection cartridge therein, a clamp lid engagable against the seat and movable between respective open and closed positions, a finger on the valve for preventing the clamp lid from being opened while the valve is open to thereby prevent the clamp lid from being opened when fluid is flowing through the valve, and a shoulder on the clamp lid for preventing the valve from being opened when the clamp lid is opened to thereby prevent the flow of fluid when the lid is open.
