Abstract
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. The tamper indicating means has a riding ramp along the inner periphery of the inner skirt to engage the loading ramp during application of the closure to the container to avoid premature removal of the tamper indicating means.
