Abstract
A partially collapsible package including a pair of opposing rigid front and rear panels. A bottom panel and a pair of side panels are hinged to the front and rear panels to form a package closed at the bottom and open at the top to receive and remove articles therethrough. Each side panel and the bottom panel has a weakened zone to permit collapse of the package in the direction bringing the front and rear panels together. An arrangement of tabs is hinged to the house and positioned so that as the package is collapsed the tabs will be free for limited movement to permit partial collapse of the package and then to support the package and resist further collapse by engagement between the moved tabs and surfaces of the package thereby providing for a partially collapsed supporting package to protect articles contained therein when the package is full and while articles are being removed and the package collapsed accordingly.
