The unsealing of the container is achieved through the coordination of camming locks, which comprise an upper ramped surface, with spike-shaped locking wedges that comprise a beveled toe portion, elongated shaft portion and camming head portion. Rotation of the cover in a first direction relative to the base portion locks the toe end and shaft portions of the spike-shaped locking wedges beneath the camming locks. Rotation in a second opposite direction relative to the base portion backs the camming head portion of the spike-shaped wedges up the upper ramped surfaces of the camming locks such that the cover is axially distanced from the container, thus unsealing the cover from the base and break…
