ABSTRACT:
An anti-backoff closure assembly includes a container and a cap. The container has a neck portion forming an opening and having a protrusion and screw threads on an outer surface of the neck portion. The cap has on an inner surface a second protrusion, grooves, and a seal for releasably engaging the opening of the neck portion to form a leak free seal. The first and second protrusions engage to create an interference fit when the screw threads and the grooves are threadably engaged. Upon engagement, the second protrusion deforms the first protrusion sufficiently to form an indentation on the first protrusion that resists backoff as the pressure between the screw threads and the grooves is reduced as a result of plastic relaxation, thereby maintaining the leak free seal of the seal within the opening.
