Abstract
Abstract Dispensing carton for a supply roll of sheet material, e.g. a foil dispenser, has closure structure including a top wall containing an elongated slot. It has a front wall with a hinged bottom edge and a free top edge associated with a cutting blade. The front wall is adapted to be moved from a position perpendicular to the bottom wall to a position in obtuse angle relationship to the bottom wall. The closure structure includes downwardly depending means which function to shield the cutting edge when the front wall is in perpendicular position and to lock the front wall in place when it is in angled position. When the carton is in use, the sheet material is threaded through the elongated slot and the front wall is locked in angled position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
207 words
Dispensing carton for a supply roll of sheet material, said carton comprising top wall means comprising panel means hinged at a rear edge and containing an elongated slot, bottom wall means, front wall means including panel means hinged at its bottom to said bottom wall means and having a free edge at its top, and movable from a position substantially perpendicular to said bottom wall means to a position in obtuse angle relationship with said bottom wall means to space said free edge outward from the panel means of said top wall means, cutter means associated with said free edge, flap means associated with said front wall means, means depending from a front edge of the panel means of said top wall means, movable by movement of the panel means of the top wall means at the hinge at its rear edge, to overlie and shield said cutter means when the panel means of said front wall means is in a position substantially perpendicular to said bottom wall means, and to interact with said flap means when the panel means of said front wall means is in a position in obtuse angle relationship with said bottom wall means to lock said front wall means in said relationship.
Claim 2
Dependent Claim
207 words
Dispensing carton for a supply roll of sheet material, said carton comprising top wall means comprising panel means hinged at a rear edge and containing an elongated slot, bottom wall means, front wall means including panel means hinged at its bottom to said bottom wall means and having a free edge at its top, and movable from a position substantially perpendicular to said bottom wall means to a position in obtuse angle relationship with said bottom wall means to space said free edge outward from the panel means of said top wall means, cutter means associated with said free edge, flap means associated with said front wall means, means depending from a front edge of the panel means of said top wall means, movable by movement of the panel means of the top wall means at the hinge at its rear edge, to overlie and shield said cutter means when the panel means of said front wall means is in a position substantially perpendicular to said bottom wall means, and to interact with said flap means when the panel means of said front wall means is in a position in obtuse angle relationship with said bottom wall means to lock said front wall means in said relationship.
Claim 3
Dependent Claim
92 words
Dispensing carton as defined in claim 1, in which the panel means of said front wall means has left and right edges, and said flap means comprises a flap extending inwardly from said left edge and a flap extending inwardly from said right edge, each of said flaps containing a free upper edge comprising an inwardly extending elongated slot, said slots being configured and positioned to receive said depending means when said front wall means is positioned in said obtuse angle relationship to thereby lock said front wall means in said relationship.
Claim 4
Dependent Claim
48 words
Dispensing carton as defined in claim 2, in which said carton has structure at each end comprising spaced wall means defining a cavity for receiving a flap of said flap means in telescoping relation when said front wall means is positioned substantially perpendicular to said bottom wall means.
Claim 5
Dependent Claim
25 words
Dispensing carton as defined in claim 3, in which said carton is assembled from a single blank with which said cutting means has been associated.
Claim 6
Dependent Claim
19 words
