A tamper indicating and child resistant package including a screw-type closure for use with a container having a threaded neck. The container is equipped with lock members along the threaded neck and a loading ramp carried on the threaded portion of the neck. The closure has concentric inner and outer skirts depending from the top and a lock tab depending from the outer skirt. A T-shaped tamper indicating means is frangibly attached to the outer skirt and to the inner skirt by means of shear webs.
