Abstract
Abstract A carton is provided wherein the cover thereof is connected to the tray by an elongated hinge panel. One elongated edge of the panel is connected to the tray and forms a first hinge-line and the opposite elongated edge of the panel is connected to the cover and forms a second hinge-line. The first hinge-line has greater flexibility than the second hinge-line. Complemental means are formed on said tray and hinge panel whereby, upon closing of the carton, the cover and hinge panel initially move as a unit about the first hinge-line as an axis through a predetermined arc and then the cover moves relative to the hinge panel about the second hinge-line as an axis through a further predetermined arc into an overlying closed position with respect to the tray.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
177 words
A carton comprising a cover having a downwardly extending back wall, a tray having an upwardly extending back wall, and an elongated inflexible hinge panel having one elongated edge thereof connected to the upper edge of said tray back wall and forming a first hinge-line and the opposite elongated edge thereof connected to the lower edge of said cover back wall and forming a second hinge-line, said first hinge-line having greater flexibility than said second hinge-line, and protruding complemental abutting means formed on said hinge panel intermediate said first and second hinge-lines and on said tray upper edge and adjacent to said first hinge-line, said abutting means engaging one another only upon said cover and hinge panel having been moved in one direction about said first hinge-line as an axis until said hinge panel is restrained in a substantially upright position against further movement of said hinge panel in said one direction while said cover continues being moved unrestrictively in said one direction about said second hingeline as an axis until said cover substantially closes said tray.
Claim 2
Dependent Claim
177 words
A carton comprising a cover having a downwardly extending back wall, a tray having an upwardly extending back wall, and an elongated inflexible hinge panel having one elongated edge thereof connected to the upper edge of said tray back wall and forming a first hinge-line and the opposite elongated edge thereof connected to the lower edge of said cover back wall and forming a second hinge-line, said first hinge-line having greater flexibility than said second hinge-line, and protruding complemental abutting means formed on said hinge panel intermediate said first and second hinge-lines and on said tray upper edge and adjacent to said first hinge-line, said abutting means engaging one another only upon said cover and hinge panel having been moved in one direction about said first hinge-line as an axis until said hinge panel is restrained in a substantially upright position against further movement of said hinge panel in said one direction while said cover continues being moved unrestrictively in said one direction about said second hingeline as an axis until said cover substantially closes said tray.
Claim 3
Dependent Claim
88 words
The carton of claim 1 wherein the complemental abutting means formed on said hinge panel includes a plurality of longitudinally spaced first protuberances extending into the interior of said carton when said hinge panel is in said upright position, said protuberances being separated from one another by relatively inflexible hinge panel portions, and the complemental abutting means formed on said tray upper edge including a corresponding number of second protuberances; said first and second protuberances engaging one another only when said hinge panel is in said upright position.
Claim 4
Dependent Claim
21 words
The carton of claim 2 wherein the portions of said hinge panel separating said first protuberances are of substantially planar configuration.
Claim 5
Dependent Claim
29 words
The carton of claim 2 wHerein the portion of each second protuberance engaged by the corresponding first protuberance comprises a protruding tapered side wall disposed adjacent said first hinge-line.
Claim 6
Dependent Claim
46 words
The carton of claim 2 wherein each second protuberance is provided with a protruding substantially transversely extending side wall disposed adjacent to said hinge-line and contacted by a distal end of the corresponding first protuberance upon said hinge panel having been moved to said upright position.
Claim 7
Dependent Claim
18 words
The carton of claim 1 wherein said first hinge-line is provided with at least one elongated cut score.
Claim 8
Dependent Claim
