Abstract
This invention provides a pre-tightening mechanism for effecting the initial application of a threaded closure on a threaded bottle neck. The pre-tightening mechanism includes a friction rail for effecting a turning movement of the closure relative to the bottle neck and a spring biased cap hold-down plate which maintains a substantially constant pressure on the closure and maintains the closure panel horizontal during the pre-tightening operation.
