Abstract
Abstract A carton for packaging an article is formed from a single piece blank and includes a bottom wall and two inner end flaps which are hingedly connected to the bottom wall. A pair of areas each having at least two parallel sides are formed in contiguous portions of the bottom wall and the inner end flaps of the carton. In the erected carton these areas form buttresses which permit a reinforced air cushion to be formed about the packaged article.
