<p>TITLE Anti-Theft Packaging Device 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. The article can be inserted in the enclosure such that the leading edge of the article is placed under the rib and the trailing edge is forced past and under the unidirectional hook shaped retention members by nondestructibly distorting the enclosure. To assist in undestructibly distorting the enclosure, one of the retention members includes a lever arm for pivoting the retention members away from the enclosure.</p> |
