ABSTRACT:
This relates to a closure cap which in addition to its threaded connection with a container neck finish is also provided with an interlock with the neck finish so as to prevent rotation of the closure cap relative to the neck finish. The neck finish includes a lower shoulder having a projecting external teeth and the closure cap is provided with a lower locking band having internal teeth which engage with the external teeth to prevent rotation of the closure cap. In the simplest form of the invention, that portion of the locking band having internal teeth is removable to release the closure cap and thus give evidence of tampering. In other embodiments, while a portion of the locking band is released, the remaining portions still have teeth which engage the teeth on the neck finish to prevent cap rotation. The remaining locking band portion is of a construction whereby when squeezed in generally diametrically opposite relation the internal teeth carried thereby will move radially outwardly and disengage from the neck finish teeth so as to release the closure cap for rotation and removal.
