ABSTRACT:
The closure cap is provided with an extension of the skirt thereof with the skirt extension having formed therein lines of weakening and having at a lower end thereof an anchoring band which, when the closure cap is applied to a container neck finish, will permanently anchor the closure cap to the container, thus preventing littering by the separate dispensing of the closure cap. The skirt extension is provided with a line of weakening arrangement which, when a cap portion is removed from the container, will rupture and which will define a tethering strap which permanently retains the cap portion to the anchoring band while permitting any required rotation and axial movement of the cap portion to facilitate cap portion removal and product dispensing.
