Abstract
Abstract A pair of relatively small spaced apart identical tray type containers for packaging products such as food are formed from a one-piece blank arranged so that, when completed with the contents enclosed, the containers can only be opened by ripping apart integral tamper-proof tear-away portions, not by just separating the flaps or panels. In some embodiments tear strips are provided across the middle panel portion to allow easy severance of the containers from each other.
