Abstract
Caps for milk or juice bottles having four screw threads with serrations. The matching threads on the containers also display serrations. The serrations on the caps and the bottles engage each other to prevent their relative rotation to prevent the opening of the closure. An applicator places the cap onto the bottles by first twisting the caps in the reverse direction to properly seat them on the bottle necks. It then reverses the direction to start the closure. The applicator first holds the cap at an angle relative to the horizon and the direction in which the bottles move on a conveyor. As a bottle moves on the conveyor, it engages the lower, tilted edge of the cap. The bottle moving on the conveyor and in contact with the cap overcomes the tension, created by gravity, holding the cap from its location where it awaited the arrival of a bottle. An extended skirt holds the cap at a height to keep the ratchet ring on the bottom of the cap at a height above the matching ratchets on the bottle to prevent their accidental engagement.
