Abstract: A threaded cap having an axially-disposed element containing an additive adapted to be engaged upon a threaded neck of a container. As the cap is tightened, the element is distorted resulting in release of the additive which is in liquid form into the container without spilling. In one embodiment, the distortion is the result of engagement of the element with corresponding structure positioned on an inner surface of the neck of the container. In another embodiment, the element is ruptured by an axially aligned plunger which is manually operable by the user.
