Abstract: A pizza container having raised bottom wall portions for air circulation underneath a pizza. This allows single-face corrugated inserts to be eliminated for cost savings. A two-piece pizza container has lid tabs hingedly joined to the lid along respective hinge lines recessed inwardly from the respective lid edges, each tab being folded along a fold line which lies generally along the respective lid edge to define an insertion portion to be received in a cut-out in a base side wall between inner and outer portions of the side wall and a portion between the insertion portion and the hinge line which is movable to effect lifting and lowering movement of the insertion portion for more easily attaching the lid and with the height of the cut-out being reduced for more effective attachment. The base has outwardly sloping side walls, and the "spring" effect of the insertion portion against the respective outer side wall portion is provided to resist downward forces on the lid to thereby protect pizza in the box.

Abstract: A two-piece container for pizza or the like. The base includes a first pair of opposite side walls having end flaps. A second pair of opposite side walls are each folded to have an outer portion and an inner portion with at least one tab on the terminal edge thereof for engaging a slot in the bottom wall. The end flaps are received between the inner and outer portions. Cut-outs are provided in the second pair of side walls for securely receiving tabs of the lid between the inner and outer portions. In one aspect, the inner and outer portions have the shapes of trapezoids providing trapezoidal-shaped second side walls to effect sloping side walls for nesting of the bases for compact storage. The sloping side walls are also provided to effect a more secure attachment of the lid to the base. In another aspect, the container is composed of corrugated cardboard and at least one fold line is provided in the bottom wall and the first pair of side walls for folding the base for disposal.

Abstract: An apparatus is provided for effecting automatic adjustments of the rotational position of a slotting head of a conventional container blank slotting machine, as required to accommodate the machine to handle container blanks of a length in excess of the maximum length of blank for which the machine was originally designed.
