Abstract
Abstract This relates to a device for identifying a product which may be placed within a carton. Most particularly, it relates to cartons for drinks served at a fast food establishment. The carton is formed of a paperboard having a plastic facing both interiorly and exteriorly. Identifying indicia is printed on the carton adjacent a corner of the carton and tabs are defined by cut lines which extend through the outer plastic layer and terminate within the paperboard core with the paperboard being radially delaminatable. Free ends of the cut lines remote from the corner are joined by a fold line. When the carton is folded to define corners, the tabs, which extend across the corners, automatically have their starting ends displaced from the plane of the paperboard so as to be radially grippable and displaceable. The projecting tabs also function as anti-stacking devices in that they project from the corners and prevent telescoped open cartons from wedging one within the other when they are stacked for ease of handling and shipment.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
141 words
A carton formed of a laminate including a core formed of a readily delaminatable material and separate inner and outer surface layers, said carton having at least one corner whereat said laminate is generally reversely folded, at least one product indentifying tab formed at said corner by a cut line through said outer surface and terminating in said core, said tab terminating at and being permanently connected to said carton along a fold line, said product identifying tab having a starting end extending partially around said corner and said fold line being remote from said starting end, and product identifying indicia on said carton generally aligned with said tab and positioned adjacent said fold line, said starting end being rounded to effect automatic separation of said tab starting end from said laminate when said laminate is folded to form said corner.
Claim 2
Dependent Claim
141 words
A carton formed of a laminate including a core formed of a readily delaminatable material and separate inner and outer surface layers, said carton having at least one corner whereat said laminate is generally reversely folded, at least one product indentifying tab formed at said corner by a cut line through said outer surface and terminating in said core, said tab terminating at and being permanently connected to said carton along a fold line, said product identifying tab having a starting end extending partially around said corner and said fold line being remote from said starting end, and product identifying indicia on said carton generally aligned with said tab and positioned adjacent said fold line, said starting end being rounded to effect automatic separation of said tab starting end from said laminate when said laminate is folded to form said corner.
Claim 3
Dependent Claim
28 words
A carton according to claim 1 wherein said tab starting end is free of said laminate and projects beyond said carton at said corner for ease of grasping.
Claim 4
Dependent Claim
25 words
A carton according to claim 1 wherein said core and said outer surface layer are differently colored to enhance the observation of a removed tab.
Claim 5
Dependent Claim
23 words
A carton according to claim 1 wherein said carton has a folded top portion, and said corner is part of said top portion.
Claim 6
Dependent Claim
26 words
A carton according to claim 4 wherein there are a plurality of said corners and there are said tabs on more than one of said corners.
Claim 7
Dependent Claim
32 words
A carton according to claim 4 wherein said folded top portion includes a top panel, said tab is primarily formed in said top panel, and said indicia is on said top panel.
Claim 8

A carton according to claim 1 wherein there are a plurality of tabs on said corner.
Claim 9
Dependent Claim
29 words
A carton according to claim 1 wherein said cut line is U-shaped and includes a pair of spaced generally parallel legs connected at free ends by said fold line.
Claim 10
Dependent Claim
21 words
A carton according to claim 1 wherein said fold line is in the form of a crush scoring of said laminate.
Claim 11
Dependent Claim
202 words
A blank for a carton, said blank being formed of a laminate including a core formed of readily delaminatable material and separate inner and outer surface layers, said blank having at least one carton panel defining fold line for defining a reversely folded carton corner between two carton panels separated by said fold line, a cut line through said outer surface layer and terminating in said core, said cut line being generally U-shaped and defining a product identifying tab, said cut line having two generally parallel legs and a bight portion, free ends of said legs being joined by a hinge forming fold line in said outer surface layer for retaining a connection between a displaced tab and an associated carton panel, said cut line extending across said carton panel defining fold line to have a starting portion in one of said panels and a hinged end in the other of said panels, and product identifying indicia on said other panel adjacent said hinge forming fold line, said tab starting end being rounded in accordance with said cut line bight portion to effect automatic separation of said tab starting end from said laminate when said laminate is folded to form said corner.
Claim 12
Dependent Claim
202 words
A blank for a carton, said blank being formed of a laminate including a core formed of readily delaminatable material and separate inner and outer surface layers, said blank having at least one carton panel defining fold line for defining a reversely folded carton corner between two carton panels separated by said fold line, a cut line through said outer surface layer and terminating in said core, said cut line being generally U-shaped and defining a product identifying tab, said cut line having two generally parallel legs and a bight portion, free ends of said legs being joined by a hinge forming fold line in said outer surface layer for retaining a connection between a displaced tab and an associated carton panel, said cut line extending across said carton panel defining fold line to have a starting portion in one of said panels and a hinged end in the other of said panels, and product identifying indicia on said other panel adjacent said hinge forming fold line, said tab starting end being rounded in accordance with said cut line bight portion to effect automatic separation of said tab starting end from said laminate when said laminate is folded to form said corner.
Claim 13
