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 readily delaminatable. 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 readily grippable and removable. The projecting tabs also function as anti-stacking devices in that they project from the corners and prevent telescoped opened 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
110 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 identifying tab formed at said corner by a cut line through said outer surface layer and terminating in said core, said product identifying tab having a starting end extending partially around said corner, and product identifying indicia on said carton adjacent said tab, said tab 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
110 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 identifying tab formed at said corner by a cut line through said outer surface layer and terminating in said core, said product identifying tab having a starting end extending partially around said corner, and product identifying indicia on said carton adjacent said tab, said tab 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

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 tab has a pointed tail end with the point of said tail end pointing towards said indicia.
Claim 5
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 6
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 7
Dependent Claim
26 words
A carton according to claim 5 wherein there are a plurality of said corners and there are said tabs on more than one of said corners.
Claim 8

16 words
A carton according to claim 1 wherein there are a plurality of tabs on said corner.
Claim 10
Dependent Claim
28 words
A carton according to claim 1 wherein said projecting tab starting end forms means for preventing wedging of cartons when said carbons are stacked in their open state.
Claim 11
Dependent Claim
140 words
A blank for a carton, said blank being formed of a laminate including a core formed of a readily delaminatable material and separate inner and outer surface layers, said blank having at least one fold line for defining a reversely folded corner between two panels separated by said fold line, a cut line through said outer surface layer and terminating in said core, said cut line defining a removable product identifying tab, said cut line extending across said fold line to have a starting portion in one of said panels and a tail portion in the other of said panels, and product identifying indicia on said other panel adjacent said tab tail portion, said tab 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 12
Dependent Claim
140 words
A blank for a carton, said blank being formed of a laminate including a core formed of a readily delaminatable material and separate inner and outer surface layers, said blank having at least one fold line for defining a reversely folded corner between two panels separated by said fold line, a cut line through said outer surface layer and terminating in said core, said cut line defining a removable product identifying tab, said cut line extending across said fold line to have a starting portion in one of said panels and a tail portion in the other of said panels, and product identifying indicia on said other panel adjacent said tab tail portion, said tab 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 13
