Abstract
A removal torque-resistant closure and container assembly is provided with the container having a thread extending around the opening. The closure includes a thread for engaging the container thread. The container includes a projection that extends from the thread root between two adjacent thread crests on the container and that defines an outer edge for temporarily deforming the closure thread during relative rotational movement of the container and closure when the container and closure are screwed together. Upon termination of the screwing action, the container projection edge is engaged with a deformed region of the closure thread so as to resist closure removal by unscrewing.
