Abstract

A reclosable, stackable, standable package for food products such as baked goods easily converts from a parallelepiped form to a widened shape on top for easy access to the snack which is contained within an inner liner bag. The package stays in a widened open configuration throughout hand-to-mouth snacking even while resting on its front or back panel. The outer carton of the package has score lines on the front and the back panels of the carton extending from the lower corners of the front and the back panels to the center of the upper edge of the front and the back panels. Score lines also extend across the center of the top front and back flaps. The score lines in combination with the disconnected top flaps design not only allows the top of the package to form a wide oval shaped opening for easy access to the packaged goods, but also allows the package to stay opened while snacking. Also, the expanded package does not tip or rock during snacking, but rather keeps in stable contact with an underlying at least substantially flat support surface.

a front top flap, a back top flap, and two opposing side top flaps, all of said top flaps each including a top edge, a bottom edge, and two opposing side edges, the bottom edge of the front flap and the top edge of the front panel being connected about a fold line, the bottom edge of the back flap and the top edge of the back panel being connected about a fold line, the bottom edges of the side flaps and the top edges of the side panels being connected about fold lines, and the side edges of all four flap panels being disconnected from each other;

the width between the side edges of each of the front panel and the back panel being substantially larger than the width between the side edges of each of the first and second side panels;

the width between the side edges of each of said front and said back panels being less than about 80% of the height between the top and the bottom edges of each of said front and said back panels;

a bottom closing holding the bottom edges of the front panel, the side panels and the back panels in a substantially rectangular configuration; and

score lines allowing the front and back panels to flex into a non-planar shape with each of the front, side, and back flaps being open and the top edges of the front, side and back panels forming a generally hexagonal shape having a distance between the centers of the front top edge and the back top edge substantially greater than the width between the side edges of each of the first and second side panels, said score lines further allowing the carton to stay open when resting on the front or the back panel, wherein two score lines extend across the front panel, one from each of the bottom corners of the front panel to the center of the top edge of the front panel, two score lines extend across the back panel one from each of the bottom corners of the back panel to the center of the top edge of the back panel, and a score line extends substantially parallel to the side edges and across the center of each of said top front and top back flaps.

2. A package as claimed in claim 1, wherein said carton is a reclosable carton, with one of said front top flap and said back top flap further comprising a tab, and the other of said front and back top flaps further comprising a slot which interlocks with said tab.

3. A package as claimed in claim 2, wherein said back top flap comprises said tab, and said front top flap comprises said slot which interlocks with said tab.

4. A package as claimed in claim 1, wherein said carton is a reclosable carton with one of said front top flap and said back top flap further comprising three tabs, and the other of said front and back top flaps further comprising a slot which interlocks with a middle tab of said three tabs.

5. A package as claimed in claim 4, wherein said back top flap comprises said tabs, and said front top flap comprises said slot which interlocks with said middle tab.

6. A package as claimed in claim 1, wherein said liner is resealable.

7. A package as claimed in claim 1, wherein said liner is spot-glued to said carton.

8. A package as claimed in claim 1, wherein said liner is not attached to said carton.

9. A blank form for a carton comprising:

a front panel, a back panel, a first side panel, and a second side panel, all of said panels each having a top edge, a bottom edge, and first and second side edges, the first edge of the front panel and the second edge of the first side panel being connected about a fold line, the second edge of the front panel and the first edge of the second side panel being connected about a fold line, the first edge of the back panel and the second edge of the second side panel being connected about a fold line;

a glue flap comprising a first side edge and a second side edge, one of said edges of said glue flap being connected about a fold line to one of said second side edge of said back panel or said first side edge of said first side panel;

a front top flap, a back top flap, and two opposing side top flaps, all of said top flaps each including a top edge, a bottom edge, and two opposing side edges, the bottom edge of the front flap and the top edge of the front panel being connected about a fold line, the bottom edge of the back flap and the top edge of the back panel being connected about a fold line, the bottom edges of the side flaps and the top edges of the side panels being connected about fold lines, and the side edges of all four flap panels being disconnected from each other;
