Abstract

A reinforced package comprising a carton comprising a plurality of panels that extends at least partially around an interior of the carton. The plurality of panels can comprise a front panel and a back panel disposed opposite to the front panel. The carton can comprise a bottom wall foldably connected to the front panel along a first curved fold line and to the back panel along a second curved fold line. The reinforced package further can include a bag at least partially attached to the carton. The bag can be at least partially defining an interior space for holding a product. The carton can be positionable in a non-erect position and in an erect position. At least the bottom wall and the first curved fold line can be configured to retain the carton in the erect position.

First claim

What is claimed is:

1. A reinforced package, comprising:
a carton comprising a plurality of panels that extends at least partially around an interior of the carton, the plurality of panels comprising a front panel, a back panel disposed opposite to the front panel, and a side panel foldably connected to at least one of the front panel and the back panel, the side panel comprising a first panel portion foldably connected to a second panel portion along a lateral fold line, each of the first panel portion and the second panel portion being a triangle, and the carton comprising a bottom wall foldably connected to the front panel along a first curved fold line and to the back panel along a second curved fold line; and
a bag at least partially attached to the carton, the bag at least partially defining an interior space for holding a product;
wherein the carton is positionable in a non-erect position wherein the interior space of the bag is at least partially collapsed and in an erect position wherein the interior space of the bag is increased, the carton is configured to support the bag in the erect position and at least the bottom wall and the first curved fold line are configured to retain the carton in the erect position.

2. The reinforced package of claim 1 , wherein the second curved fold line is configured to retain the carton in the erect position along with at least the bottom wall and the first curved fold line.

3. The reinforced package of claim 1 , wherein the bottom wall is foldable along at least the first curved fold line and the second curved fold line when moving the carton between the non-erect position and the erect position.

4. The reinforced package of claim 1 , wherein a bottom fold line extends in the bottom wall and is spaced apart from the first curved fold line and the second curved fold line, and the bottom wall is foldable along at least the first curved fold line, the second curved fold line, and the bottom fold line when moving the carton between the non-erect position and the erect position.

5. The reinforced package of claim 4 , wherein the bottom wall comprises a first bottom end flap foldably connected to the front panel along the first curved fold line and a second bottom end flap foldably connected to the back panel along the second curved fold line, and the first bottom end flap and the second bottom end flap are in an at least partially overlapped relationship to at least partially form the bottom wall.

6. The reinforced package of claim 5 , wherein the bottom fold line extends in at least one of the first bottom end flap and the second bottom end flap.

7. The reinforced package of claim 1 , wherein each of the first curved fold line and the second curved fold line is concave with respect to the bottom wall.

8. The reinforced package of claim 1 , wherein the front panel comprises at least a front center portion foldably connected to a first front corner portion along a first oblique fold line and to a second front corner portion along a second oblique fold line.

9. The reinforced package of claim 8 , wherein the back panel comprises at least a back center portion foldably connected to a first back corner portion along a third oblique fold line and to a second back corner portion along a fourth oblique fold line.

10. The reinforced package of claim 1 , wherein the side panel is a first side panel, the lateral fold line is a first lateral fold line, the plurality of panels further comprises a second side panel foldably connected to at least one of the front panel and the back panel, the second side panel comprises a third panel portion foldably connected to a fourth panel portion along a second lateral fold line, and each of the third panel portion and the fourth panel portion is a triangle.

11. A reinforced package, comprising:
a carton comprising a plurality of panels that extends at least partially around an interior of the carton, the plurality of panels comprising a front panel and a back panel disposed opposite to the front panel, the carton comprising a bottom wall foldably connected to the front panel along a first curved fold line and to the back panel along a second curved fold line; and
a bag at least partially attached to the carton, the bag at least partially defining an interior space for holding a product;
wherein the carton is positionable in a non-erect position wherein the interior space of the bag is at least partially collapsed and in an erect position wherein the interior space of the bag is increased, the carton is configured to support the bag in the erect position and at least the bottom wall and the first curved fold line are configured to retain the carton in the erect position;
wherein the front panel comprises at least a front center portion foldably connected to a first front corner portion along a first oblique fold line and to a second front corner portion along a second oblique fold line, and the first oblique fold line and the second oblique fold line at least partially converge at a top edge of the carton.

12. The reinforced package of claim 11 , wherein the first oblique fold line and a first end of the first curved fold line at least partially converge, and the second oblique fold line and a second end of the first curved fold line at least partially converge.

13. The reinforced package of claim 11 , wherein the plurality of panels further comprises a first side panel and a second side panel, the first front corner portion is foldably connected to the first side panel along a third oblique fold line, the second front corner portion is foldably connected to the second side panel along a fourth oblique fold line, the first oblique fold line, the third oblique fold line, and the first curved fold line at least partially converge, and the second oblique fold line, the fourth oblique fold line, and the first curved fold line at least partially converge.

14. The reinforced package of claim 13 , wherein each of at least the first front corner portion, the second front corner portion, the first side panel, and the second side panel is a triangle.
