Abstract
The present invention is directed to a container apparatus and method for packaging contoured articles, particularly contoured articles containing hazardous substances. The container apparatus comprises a base member, upstanding sidewall members foldably emanating from the edges of the base member, and an article retaining member foldably emanating from the top edge of at least one of the sidewall members. The article retaining member is positionable toward and into the inner region of the container so as to form an acute angle with the sidewall from which it emanates. The article retaining member further includes an article retention edge to engage, stabilize, and prevent undesired movement of the contoured article(s) housed within the interior region of the container apparatus. In particular, the article retaining member prevents migration of the contoured articles in a vertical plane, in a horizontal plane, and in a rotational direction. Preferably, the container apparatus is constructed from a substantially unitary paperboard blank, and may include a dividing member for compartmentalizing the inner region of the container apparatus.
