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.

Venting/opening for paperboard carton

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.

Front loaded display carton

Carton blank

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. The partial depth cut lines allow the portion of the tray flange outboard of the cut lines to be broken away from the continuous flange and used to lift the corner of the lid, thereby interrupting the bond between the lid and flange for venting and opening the carton

Two way opening for a tray type carton

A bottle type container is fabricated by blow molding a continuous wall liner of thermoplastic polymer integrally to the interior wall surface of an oppositely matched pair of paperboard cladding jackets. Paperboard cladding jackets respective to each pair are joined substantially edge-to-edge along the meeting seam exclusively by the continuous liner wall lap. For container stability when resting on a flat surface, at least one folded ridge is formed in the bottom edge panel of both jackets.
