Abstract: A venting/opening means for an ovenable carton having a separate lid with venting and opening instructions printed on one corner, and a tray with a continuous peripheral flange. The improvement wherein the venting/opening means is applied to each corner of the tray flange for polygonal shaped cartons having side walls of equal length, or to designated diagonally opposed corners of trays of rectangular shape so as to provide a venting/opening means under the printed instructions on the lid notwithstanding how the lid is oriented on the tray. The venting/opening means takes the form of partial depth cut lines, cut score lines or the like arranged diagonally across the corners of the tray flange. These cut lines provide corner tabs which may be separated from the tray flange to allow the tray to be opened by fracturing the portion of the tray flange outboard of the cut lines and first partially lifting the lid to vent the carton, and then finally opening the carton by lifting the lid completely off the tray.

Abstract: A front loaded display carton is formed from a one-piece, cut and scored blank of paperboard or the like that is preglued and shipped to the user in a collapsed condition. The carton when squared is of essentially rectangular configuration with a display opening in the front wall and a product containing pocket located interiorly of the carton beneath the display opening. The product containing pocket is formed by internal walls known generally as header panels and stop panels which are cut from the one-piece blank.

Abstract: A venting/opening scheme for tray type cartons, wherein the tray has a continuous, upper peripheral flange to which a lid is bonded, and the tray includes opening instructions printed on a side wall for opening one of two adjacent corners of the tray, the improvement wherein a venting/opening means is applied to the tray flange at both of the two adjacent corners of the tray where the opening instructions are printed. The application of a venting/opening means at each corner allows the cartons to be opened by peeling the lid off from left-to-right or from right-to-left. The venting/opening means comprises partial depth cut lines located in the underside of the tray flange at each adjacent corner of the tray.

Abstract: A flanged tray for packaging, storing, heating and serving food products comprises a plurality of compartments with each compartment pair having adjacent foldably attached walls which form a partition panel between the paired compartments. Each compartment includes gusset corner closures to provide a leak proof construction and additional glue tabs may be provided at each corner to reinforce the gussets and support the flange in a substantially horizontally disposed condition for lidding. The blank for constructing the tray is cut and scored to yield adjacent partition panels which remain substantially perpendicular to their base panels and in full face-to-face contact with one another when the tray compartments are formed so that the paired compartments are self supporting.

Abstract: A carton for food products or the like comprises a combination lid and tray with a bottom locking means for securing the lid and tray when the carton is closed. The bottom locking means comprises a locking tongue integral with an extended portion of the lid component which engages a locking slot formed in the bottom of the tray component. The locking tongue comprises a tab element formed as a part of a flap foldably attached to an extension of the front wall of the lid. The locking slot comprises a cut out formed substantially along the fold line between the bottom wall and front wall of the tray.

Abstract: A generally rectangular carryout tray for fast food restaurants is provided with top, bottom and side walls. The top wall includes openings in distinct areas for accomodating different kinds of food. The tray is constructed so taht it can be collapsed for storage before use and readily erected for use with a simple motion. The top wall is supported above the bottom wall by an integral bridge element prepared from the top wall material taken from one of the food accomodating areas. Each food accomodating area also includes deflectable flap elements and tabs which further support and position the various food products in their designated areas.
