Abstract
A tamper-proof package having a container and closure is disclosed. The container has a threaded neck and an outwardly projecting flange beneath the container threads. The cap has a top wall and a downwardly depending sidewall with the sidewall having inwardly projecting, helical threads for cooperation with the container threads. Provided as part of the cap is an annular cap flange which is disposed beneath the cap sidewall and adapted for connection to the container flange. Holding the annular cap flange to the cap body is achieved by the utilization of a plurality of elongated connecting ribs. These connecting ribs extend downward from the cap sidewall to the cap flange and have a direction of slope opposite the direction of the helix angle of the cap helical thread.
