Abstract: An anti-theft packaging device is disclosed, according to the teachings of the present invention as including a generally closed enclosure having an open side allowing insertion of the article to be packaged such as a recording tape. The preferred embodiment of the present invention then further includes an extension for extending the dimensions of the enclosure and thus of the particle to be packaged. The article is held against removal in the enclosure by nondestructibly, deformable dimples shown in the preferred embodiment as being disc-shaped. The preferred dimples are deformable from a first position located outside of the extension allowing the article to be passed through the extension and into the enclosure and a second position located inside of the extension for abutting with the article when it is located within the enclosure for preventing removal of the article from the enclosure.

Abstract: An anti-theft packaging device is disclosed, according to the teachings of the present invention, as including an enclosure having a generally open top face allowing insertion of the article to be packaged. The preferred enclosure then further includes an extension for extending the dimensions of the enclosure and thus of the article to be packaged. The article is held against removal in the enclosure by generally closed sides, ends, and bottom face and is held against movement or removal through the open top face by retention devices. Again, in the preferred embodiment, the retention devices are shown as a rib formed in the top face adjacent one side of the enclosure and has unidirectional hook shaped retention members located adjacent to the other side of the enclosure.
