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.
Claims12
A closure system for a container, comprising:
- a container terminating in a neck terminating in an end, said neck comprising one of an indexing groove and an indexing key on an exterior portion thereof;
- a closure further comprising the other of an indexing key and an indexing groove for selective insertion of said key into said indexing groove to prevent relative rotation between said closure and said neck;
- a machine to join said closure to said neck;
- a first support surface on said closure selectively engaging a second support surface on said neck to guide said closure during relative rotation, caused by said machine, with respect to said neck where said indexing key provides no substantial resistance to said relative rotation which facilitates alignment of said key with said indexing groove for securing said closure to said neck with said machine.
