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.

A removal torque-resistant closure and container assembly comprising: a container defining an opening and a thread extending around said opening; a closure for being applied to said container to occlude said opening, said closure defining a thread extending around said closure for threadingly engaging said container thread, said container thread having its adjacent turns spaced apart at the thread root; and a projection that (1) extends radially from the container thread root, (2) extends in the axial direction across the entire width of the thread root to merge with each of said two adjacent thread turns on said container, and (3) defines a generally rigid outer edge for temporarily deforming said closure thread during relative rotational movement of said container and closure when said closure and container are screwed together whereby upon termination of the screwing action, said container projection outer edge is engaged with an adjacent deformed region of said closure thread so as to resist closure removal by unscrewing.
