Abstract

This relates to a sealed carton formed of paperboard which is provided with tamper indicating features. First of all, the ends of the carton are formed of a combination of partial and full closure flaps and the full closure flaps are provided with weakened areas so that if the closure flaps are attempted to be separated, there will be a rupture of either one or both of the full closure flaps so as to indicate attempted tampering. On the other hand, if an attempt is made to open the carton along the joint between the body panel and the connecting panel, the connecting panel carries at opposite ends thereof closure flaps which are incorporated in the ends of the carton and there is a weakening line arrangement such that rupture of the closure flaps carried by the connecting panel from the connecting panel will occur to indicate an attempt to tamper.
