ABSTRACT:
A closure system for a container reduces the needed torque for assembly by minimizing frictional resistance to rotation of the closure into its desired alignment with the container before the closure is driven home onto the container neck. The reduction in the torque resistance during the application of the closure allows the rotary filling machinery to work within its torque limits and minimizes damage to the parts during the filling and sealing operation in a bottle filling line.
