ABSTRACT:
A consumer friendly package including a plastic closure having multiple threads which engage multiple threads on the finish of a plastic container. The closure has at least one and preferably four radially inwardly extending lugs that engage a radial abutment on the finish of the container to provide an audible click when the closure is fully applied. The finish of the container is provided with at least one, preferably two axial projections that extend downwardly from the threads on the finish and are engaged by the threads on the closure to retard back-off of the closure and eliminate the effects upon sealing of stack up between the tolerances of manufacture of the finish, closure and liner in the closure.
