Total Claims: 6
Claim 1
Independent Claim 170 words
A carton, formed of a unitary blank of foldable paperboard, including intergral structure for holding in a fixed position, a generally rectangular tray having a flange projecting laterally outward from an upper portion thereof, said carton comprising: (a) a pair of opposed top and bottom horizontal walls; (b) opposed pairs of side and end vertical walls foldably joined to each other on first fold lines and to said horizontal walls on second fold lines, which extend normal to said first fold lines, to define a box-like enclosure; and (c) retaining panels foldably joined to opposite ends of said opposed end vertical walls, each of said retaining panels having at its outer end a downwardly extending projection and at its inner end a recessed shoulder to provide an abutment in which the shoulder receives the upper portion of a flange of a tray, and the projection extends downwardly against the top of the tray and inboardly of the flange to hold the tray in a fixed position against said bottom wall.
Claim 2
Dependent Claim 170 words
A carton, formed of a unitary blank of foldable paperboard, including intergral structure for holding in a fixed position, a generally rectangular tray having a flange projecting laterally outward from an upper portion thereof, said carton comprising: (a) a pair of opposed top and bottom horizontal walls; (b) opposed pairs of side and end vertical walls foldably joined to each other on first fold lines and to said horizontal walls on second fold lines, which extend normal to said first fold lines, to define a box-like enclosure; and (c) retaining panels foldably joined to opposite ends of said opposed end vertical walls, each of said retaining panels having at its outer end a downwardly extending projection and at its inner end a recessed shoulder to provide an abutment in which the shoulder receives the upper portion of a flange of a tray, and the projection extends downwardly against the top of the tray and inboardly of the flange to hold the tray in a fixed position against said bottom wall.
Claim 3
Dependent Claim 188 words
A carton, formed of a unitary blank of foldable paperboard, including integral structure for holding in a fixed position, a generally rectangular tray having a flange projecting laterally outward from an upper portion thereof, said carton comprising: (a) a pair of opposed top and bottom horizontal walls; (b) opposed pairs of outer end wall panels foldably joined to opposite ends of said top wall; (c) opposed pairs of inner end wall panels foldably joined to opposite ends of said bottom wall; (d) retaining panels formed of a first section and a second section and foldably joined to each other and to said inner end wall panels, said first sections of said retaining panels being disposed at an angle less than ninety degrees with respect to said related inner end wall panels, said second sections of said retaining panels being disposed generally normal to said related first sections; and (e) said first and second sections of said retaining panels having a laterally extending opening to provide a corner structure receiving a portion of a flange of the tray to maintain it in a fixed position against said bottom wall.
Claim 4
Dependent Claim 188 words
A carton, formed of a unitary blank of foldable paperboard, including integral structure for holding in a fixed position, a generally rectangular tray having a flange projecting laterally outward from an upper portion thereof, said carton comprising: (a) a pair of opposed top and bottom horizontal walls; (b) opposed pairs of outer end wall panels foldably joined to opposite ends of said top wall; (c) opposed pairs of inner end wall panels foldably joined to opposite ends of said bottom wall; (d) retaining panels formed of a first section and a second section and foldably joined to each other and to said inner end wall panels, said first sections of said retaining panels being disposed at an angle less than ninety degrees with respect to said related inner end wall panels, said second sections of said retaining panels being disposed generally normal to said related first sections; and (e) said first and second sections of said retaining panels having a laterally extending opening to provide a corner structure receiving a portion of a flange of the tray to maintain it in a fixed position against said bottom wall.
