Claim 2

A carton having a compact six-sided closed storage position and an enlarged open pan use position formed from a flat rectangular blank of carton forming board having transverse and longitudinal score lines defining five central panels and a row of end panels on both ends of the central panels, diagonal score lines dividing the middle end panels into a plurality of triangular subpanels, said blank being folded about said score lines with the triangular subpanels overlapped against one of the adjacent central panels, with the end panels on one side of the triangular subpanels underlapped against the next adjacent central panel and with the end panels on the central panel adjoining said end panel underlapped central panel having the end panels thereon tucked between the remaining end panels to provide a six-sided closed carton adapted to be unfolded into an opentopped closed-bottomed pan with vertical sidewalls surrounding the bottom and having corner end panels in overlapped relation with adjacent panels and means for uniting the overlapped panels for maintaining the sidewalls in said vertical position.

Claim 3

A folding carton having a compact, six-sided closed position and an enlarged open-topped closed-bottom position with upstanding sidewalls defining a use area, said carton formed from a flat rectangular blank of carton forming board having transverse and longitudinal score lines defining five central panels, each with end panels on both ends thereof, slots separating the corner end panels from the next adjacent end panels, diagonal score lines dividing the middle end panels into two triangular subpanels, said carton forming board being folded with the triangular subpanels in overlapped relation, the corner end panels on one end of the board inserted between the end panels on the next adjacent central panel, the end panels on the central panel next adjacent the overlapped triangular subpanels being folded into underlapped relation with said next adjacent central panel to provide a double thickness cover for the carton, and the remaining corner end panels being tucked between the other corner end panels and the end panels overlying said other corner end panels, pressure sensitive adhesive on the corner end panels for uniting them to the next adjacent end panels in the open use position of the carton, and removable protective tapes covering said adhesive.

Claim 4

A folding carton having a compact, six-sided closed position and an enlarged open-topped closed-bottom position with upstanding sidewalls defining a use area, said carton formed from a flat rectangular blank of carton forming board having transverse and longitudinal score lines defining five central panels, each with end panels on both ends thereof, slots separating the corner end panels from the next adjacent end panels, diagonal score lines dividing the middle end panels into two triangular subpanels, said carton forming board being folded with the triangular subpanels in overlapped relation, the corner end panels on one end of the board inserted between the end panels on the next adjacent central panel, the end panels on the central panel next adjacent the overlapped triangular subpanels being folded into underlapped relation with said next adjacent central panel to provide a double thickness cover for the carton, and the remaining corner end panels being tucked between the other corner end panels and the end panels overlying said other corner end panels, pressure sensitive adhesive on the corner end panels for uniting them to the next adjacent end panels in the open use position of the carton, and removable protective tapes covering said adhesive.

Claim 5

A carton which comprises a six-sided box formed from a flat sheet of fibrous board material having transverse and longitudinal score lines defining five central panels, each with end panels on both ends thereof, slots separating the corner end panels from the next adjacent end panels and diagonal score lines dividing the middle end panels into two triangular subpanels, said sheet being folded about said score lines into said six-sided box, said boX being openable from said six-sided position into an open topped closed bottom pan position with vertical walls surrounding the bottom and with the corner panels lapping the next adjacent end panels, pressure sensitive adhesive on the free ends of the corner panels, and protective tapes covering said adhesive to be stripped from said adhesive in the open pan position of the carton to expose the adhesive for uniting and sealing the overlapped end panels.

Claim 6

A carton which comprises a six-sided box formed from a flat sheet of fibrous board material having transverse and longitudinal score lines defining five central panels, each with end panels on both ends thereof, slots separating the corner end panels from the next adjacent end panels and diagonal score lines dividing the middle end panels into two triangular subpanels, said sheet being folded about said score lines into said six-sided box, said boX being openable from said six-sided position into an open topped closed bottom pan position with vertical walls surrounding the bottom and with the corner panels lapping the next adjacent end panels, pressure sensitive adhesive on the free ends of the corner panels, and protective tapes covering said adhesive to be stripped from said adhesive in the open pan position of the carton to expose the adhesive for uniting and sealing the overlapped end panels.

Claim 7

The carton of claim 3 wherein the score lines for forming the closed and opened box shape include five transverse score lines parallel with the end edges of the blank and two longitudinal score lines parallel with the side edges of the blank, said diagonal score lines bisecting the middle end panels formed by the transverse and longitudinal score lines.

Claim 8

The carton of claim 3 wherein the sheet material has a moisture-impervious cover.
