Abstract: A blank from which may be erected a protective enclosed tamper evident container for the packaging of articles during transportation and storage has five aligned panels that form opposed roof and floor walls having a dome shape connected at opposite ends of the container by side walls having a concave shape. The centre panel forming the floor wall has opposed closure panels that fold over the roof wall to close the open sides of the container and are provided with locking tongues that engage slots in the roof wall to secure the container. The tongues and slots provide a tamper evident mechanism for securing the container such that no adhesive is required during the erection process in order to hold the container in its closed position.
