Abstract
A liquid chemical handling system is suitable for handling a liquid chemical during dispensing. A container holds the liquid chemical and a collar couples the container to a dispenser during dispensing. A coupling clip, has a lever portion pivotally coupled to the collar. The coupling clip also has a locking tab pivotally coupled to a lever portion so that depression of the lever portion causes the locking tab to move between a locking position and an unlocking position. The coupling clip is also provided with a bias mechanism, which is coupled to the coupling clip, and which biases the lever portion to hold the locking tab in the locking position.
