Abstract
Abstract This disclosure relates to a carton which includes a tear panel adapted to be opened to form a pour opening, and is particularly directed to means for releasably securing the tear panel to an underlying wall portion of the carton whereby the tear panel cannot be inadvertently and/or accidentally opened, and the releasable means constitutes a minor surface area of adhesion between the tear panel and the underlying wall portion whereby the tear panel can be readily ruptured relatively evenly and accurately along tear lines thereof.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
195 words
A carton blank adapted when set up to include an openable pour opening comprising a generally rectangular body-forming blank constructed from fibrous shearable peelable material, a plurality of transverse fold lines setting off a plurality of body-forming panels, a first of said body-forming panels being defined by a first of said plurality of transverse fold lines and an adjacent first transverse terminal edge, a second of said body-forming panels being disposed at an end of said blank opposite said first panel and being defined by a second of said plurality of transverse fold lines and an adjacent second transverse terminal edge, said second panel being adapted for overlying adhesive securement to said first panel, said first panel having means defining an openable pour opening, said second panel having means defining a tear panel for normally exteriorly overlapping said pour opening defining means, and one of said first and second panels having means in only one exterior surface thereof defining a removable peelable surface area between said tear panel and said first panel contiguous the pour opening defining means whereby only said peelable surface area is removed to release said tear panel from its closed position.
Claim 2
Dependent Claim
195 words
A carton blank adapted when set up to include an openable pour opening comprising a generally rectangular body-forming blank constructed from fibrous shearable peelable material, a plurality of transverse fold lines setting off a plurality of body-forming panels, a first of said body-forming panels being defined by a first of said plurality of transverse fold lines and an adjacent first transverse terminal edge, a second of said body-forming panels being disposed at an end of said blank opposite said first panel and being defined by a second of said plurality of transverse fold lines and an adjacent second transverse terminal edge, said second panel being adapted for overlying adhesive securement to said first panel, said first panel having means defining an openable pour opening, said second panel having means defining a tear panel for normally exteriorly overlapping said pour opening defining means, and one of said first and second panels having means in only one exterior surface thereof defining a removable peelable surface area between said tear panel and said first panel contiguous the pour opening defining means whereby only said peelable surface area is removed to release said tear panel from its closed position.
Claim 3
Dependent Claim
19 words
The carton blank as defined in claim 1 wherein said removable area defining means is a line of weakness.
Claim 4
Dependent Claim
40 words
The carton blank as defined in claim 1 wherein said removable area defining means is a continuous line of weakness disposed between one of said first and second transverse fold lines and said respective first and second transverse terminal edges.
Claim 5
Dependent Claim
54 words
The carton blank as defined in claim 1 wherein said tear panel includes a cut line defining a locking tab, and the distance between the cut line and said second transverse fold line is at least in part greater than the normal distance between said first fold line and said first transverse terminal edge.
Claim 6
Dependent Claim
54 words
The carton blank as defined in claim 2 wherein said tear panel includes a cut line defining a locking tab, and the distance between the cut line and said second transverse fold line is at least in part greater than the normal distance between said first fold line and said first transverse terminal edge.
Claim 7
Dependent Claim
45 words
The carton blank as defined in claim 1 including adhesive means securing said second panel upon said first panel with said tear panel in overlying relationship to said pour opening defining means, and adhesive means between said tear panel and said removable peelable surface area.
Claim 8
Dependent Claim
20 words
The carton blank as defined in claim 6 wherein said surface area defining means is a continuous line of severance.
Claim 9
Dependent Claim
33 words
The carton blank as defined in claim 6 wherein said first transverse terminal edge is parallel but spaced from said second trAnsverse fold line to in part define said pour opening defining means.
Claim 10
Dependent Claim
54 words
The carton blank as defined in claim 8 wherein said panel includes a cut line defining a locking tab, and the distance between said cut line and said second transverse fold line is at least in part greater than the normal distance between said second transverse fold line and said first transverse terminal edge.
Claim 11
Dependent Claim
99 words
The carton blank as defined in claim 6 wherein said means defining said removable peelable surface is a continuous line of severance disposed between said first transverse fold line and said first transverse edge, said tear panel includes a cut line defining a locking tab, said peelable surface area being adhesively secured to said tear panel between said cut line and said second transverse edge, and the distance between said cut line and said second transverse fold line is at least in part greater than the normal distance of the first transverse edge from the first transverse fold line.
