Abstract
A non-removable closure assembly for connecting a manually actuated liquid dispenser to a container includes a closure cap having internal threads for mating engagement with similar threads on the outside of the container neck finish, both the cap and the neck finish having mutually engageable ratchet teeth locking the closure onto the container. The teeth inside the cap each have a trailing face extending radially at an upper end thereof and lying in a plane sloping toward the thread loosening direction of the cap at an angle greater than or equal to 1.degree. relative to the central axis of the cap for creating a camming action between the closure teeth and the neck finish teeth tending to cam the closure down on the container in response to closure rotation in the loosening direction.
