ABSTRACT:
A tamper indicating child resistant package including a screw type closure for use with a container having a threaded neck portion. The package is comprised of a lock member on a container adjacent to the threaded neck, a closure having a top with coaxial inner and outer skirts, one or more lock elements depending from the outer skirt. The lock member is engageable with the lock elements to deflect the outer skirt to permit clearance of the lock elements and lock member upon closing of the closure relative to the container. The lock element is further deflectable radially outwardly upon radial inward squeezing of the outer skirt to clear the lock member upon removal of the closure from the container. A tamper indicating means is provided to maintain the lock element in circumferentially aligned relationship relative to the lock member, and is further provided with stop elements to cooperatively engage the stop lugs on the container. The tamper indicating means prevents removal of the closure before separating the tamper indicating means from the remainder of the closure giving evidence that the container has been tampered with.
