Abstract
Abstract A container having an open neck portion formed with a screw thread and a removable closure having a side wall portion formed with a mating screw thread. The closure has at least one protuberance on the side wall. The neck portion has at least one projection shaped to allow said protuberance to pass thereover in either direction when the closure is threaded on or off of the neck portion using an applied rotational force only. The projection extends downwardly away from the screw thread toward the neck portion/container interface. The protuberance requires an applied rotational force to enable same to pass over the projection wherein the closure can be partially unthreaded from the neck portion before the protuberance passes over the projection.
