ABSTRACT:
A collapsible container formed of flexible plastic has complimentary parallel side wall members hingedly connected at their ends by complimentary end walls members and hingedly carrying complimentary bottom panels which fold down to rest upon ledges on the side wall members and end wall members. Diagonally opposed corner portions of the side wall members space the hinge axes of the end wall members away from the side wall members so that, when collapsed, an end wall member and a side wall member are coplanar and in spaced parallel adjacent relationship to the other end wall member and side wall member to sandwich the foled up bottom panels, therebetween.
The length of each side wall member is generally twice the effective length of an end wall member to provide a container which is modular for locking together with other such containers, when stacked in alignment or cross-tied. Most of the hinge pins are integrally formed with the wall members and panels to snap into place. Openings in the side wall members permit pricing of articles and opening in the bottom panels permit the use of vertically movable loading rods for automatically stacking articles in the container.
In a second embodiment inclined alignment lugs draw in the wall members in when one container is stacked on the next.
