After the tabs are inserted into the slots, the boxes are shifted laterally into alignment with each other and the hook-shaped tabs overlap the bottom of the upper box. Box blanks are disclosed for making the upper and lower boxes with the interlock tabs positioned so that the box blanks can be nested for saving material. A corner interlock is disclosed for latching the interlock tab in the locked position.

Abstract: A collapsible container is fashioned from a unitary blank of paperboard. The container is in the general form of a lower and truncated tray having a top closure lid hingedly secured to the top of the rear wall of the tray. After glueing of the lower tray, the tray is collapsed by bowing its side walls inwardly so that the entire tray may assume a substantially flattened configuration. The flattened container may then be shipped to a retail establishment, such as a fast food outlet, for subsequent set up or erection by merely unfolding the tray and pushing its sidewalls outwardly. In order to overcome the natural tendency of the sidewalls to resume their inwardly bowed configuration, having been stored in this shape for, typically, a substantial length of time, the sidewalls are provided with a novel latching slit and corner tab configuration which maintains the sidewalls in their desired substantially planar form.

Abstract: A receptacle includes pairs of opposed side panels which are connected by connector flaps.

Abstract: A container for a flat food product is formed from a one-piece blank to provide a multisided container having a front panel, first and second opposing side panels, third and fourth opposing side panels, first and second perforated portions interconnecting said first and third opposing side panels and said second and fourth opposing side panels, respectively, a rear panel, and a top. The six-sided design provides less air space in the container, thus contributing to the maintenance of the temperature of the food product contained therein. Lock tabs located on minor flaps of the front panel secure the first and second opposing side panels into an upright position by interlocking under portions of the side panels. The perforated portions provide continuity between the side panels, and automatically provide hot air ventilation outlets when the container is assembled.

End panel securing flaps are hingedly connected to each of the end foldover panels, and are received through aligned and correspondingly sized slots in the side wall panels. The end wall securing flaps are folded into parallel abutting contact with the interior planar surface of the adjacent side wall panel, and are secured thereto using a releasable fastener such as mating hook and loop type fasteners. Each end wall panel defines a centered handgrip opening, and a folded rim or shoulder extending along the length of the top edge of the end wall panel.

Abstract: A tray for transporting a single slice of pizza while facilitating use of the tray as a support so that the piece of pizza can be removed from and repositioned on the tray during eating thereof. The tray includes a generally triangular bottom wall and a pair of low-height side walls which extend along opposite identical side edges of the bottom wall. The other or base edge of the tray is open to facilitate movement of a piece of pizza either onto or off of the tray. The tray is formed from a flat blank constructed preferably of corrugated paperboard, with fold lines separating the low side walls from the bottom wall so that the side walls can be folded upwardly to be generally perpendicular to the bottom wall. One of the side walls has a latching tab integrally associated therewith and foldable so as to wrap around one end of the other side wall for insertion into an elongate slot which extends along the fold between the other side wall and the bottom wall to latch the tray in its assembled position.

Abstract: A paperboard tray and unitary blank for forming it. Two of the tray blanks may be joined in tandem to form, after erection, a clamshell type carton. The tray is provided with cooperating latching tongues and latching slits to maintain it erected. The specific form of the latching tongues and slits enables the tray sides to tilt outwardly after initial tongue and slit engagement and thus permit stacking. The use of the tongue and slit of this invention also permits tray formation without the need of adhesives, thus permitting safe use of the tray or clamshell carton in serving food, as at the retail level.
