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.
Claims20
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 a key on an exterior potion 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 first support surface on said closure selectively engaging a second support surface on said neck to support said closure in a position where said indexing member provides no substantial resistance to relative rotation between said closure and said neck to facilitate alignment of said key with said indexing groove.
A method of mounting a closure on the neck of a container, comprising:
- providing an indexing key on one of said closure and said neck;
- providing an indexing groove on the other of said closure and said neck
- temporarily supporting the closure on the neck so that said key does not provide substantive resistance to relative rotation between said neck and said closure as said key is brought into alignment with said indexing groove.
