Abstract

A reinforced package for holding a product. The reinforced package comprises a carton comprising a plurality of panels that extend at least partially around an interior of the carton. The plurality of panels can comprise a front panel, a first side panel foldably connected to the front panel, a second side panel foldably connected to the front panel, at least one back panel foldably connected to at least one of the first side panel and the second side panel, and at least one bottom panel foldably connected to at least one of the front panel and the back panel. A bag can comprise an at least partially open end, an at least partially closed end, and an interior space for holding a product. The bag can be at least partially received in the interior of the carton. The carton is positionable in a non-erect position and in an erect position.

First claim

What is claimed is:

1. A reinforced package for holding a product, the reinforced package comprising:
a carton comprising a plurality of panels that extend at least partially around an interior of the carton, the plurality of panels comprising a front panel, a first side panel foldably connected to the front panel, a second side panel foldably connected to the front panel, at least one back panel foldably connected to at least one of the first side panel and the second side panel, a first bottom panel foldably connected to the back panel, and a second bottom panel foldably connected to the front panel;
a bag comprising an at least partially open end, an at least partially closed end, and an interior space for holding a product, the bag being at least partially received in the interior of the carton, wherein the bag comprises a first sidewall and a second sidewall, and the at least partially closed end of the bag comprises a first gusset panel foldably connected to a second gusset panel along a first fold line, the first sidewall is foldably connected to the first gusset panel along a second fold line, and the second sidewall is foldably connected to the second gusset panel along a third fold line;
wherein the carton is positionable in a non-erect position wherein the interior space of the bag is at least partially collapsed and the first gusset panel and the second gusset panel are at least partially folded with respect to one another and in an erect position wherein the interior space of the bag is increased and the first gusset panel and the second gusset panel are expanded, and the carton is configured to support the bag in the erect position;
wherein the first bottom panel and the second bottom panel at least partially overlap one another in the interior of the carton when the carton is in the non-erect position.

2. The reinforced package of claim 1 , wherein the at least partially closed end of the bag is at least partially received in the interior of the carton.

3. The reinforced package of claim 1 , wherein the bag is at least partially glued to an interior surface of at least one of the front panel and the back panel.

4. The reinforced package of claim 3 , wherein at least one of the first sidewall and the second sidewall of the bag is glued to the interior surface of the at least one of the front panel and the back panel.

5. The reinforced package of claim 1 , wherein each of the first sidewall and the second sidewall of the bag extends generally upwardly from the at least partially closed end of the bag.

6. The reinforced package of claim 5 , wherein the first sidewall and the second sidewall are attached to one another by at least one seam extending along a marginal area of the bag.

7. The reinforced package of claim 6 , wherein the at least one seam comprises at least a first seam and a second seam, the first seam and the second seam extending along respective marginal areas of the bag.

8. The reinforced package of claim 6 , wherein the at least one seam comprises at least one glue area extending along each of the first sidewall and the second sidewall, and respective portions of the at least one glue area in the first sidewall and the second sidewall are at least partially glued in face-to-face contact.

9. The reinforced package of claim 8 , wherein the at least one glue area further extends along at least a portion of the at least partially closed end of the bag, at least a portion of the at least one glue area in the at least partially closed end being at least partially glued to another portion of the at least one glue area in the at least partially closed end to form at least one sealed corner of the bag.

10. The reinforced package of claim 9 , wherein the at least one seam comprises at least a first seam and a second seam, the at least one glue area comprises at least a first glue area and a second glue area, and the at least one sealed corner comprises a first sealed corner and a second sealed corner.

11. The reinforced package of claim 5 , wherein the first gusset panel and the second gusset panel are generally coplanar with each other when the carton is in the erect position and are at least partially folded with respect to one another along the first fold line when the carton is in the non-erect position.

12. The reinforced package of claim 11 , wherein the first gusset panel and the second gusset panel are disposed generally between the first sidewall and the second sidewall when the carton is in the non-erect position.

13. The reinforced package of claim 1 , wherein the first side panel comprises a first panel portion foldably connected to a second panel portion along a first lateral fold line, and the second side panel comprises a third panel portion foldably connected to a fourth panel portion along a second lateral fold line.

14. The reinforced package of claim 13 , wherein the first panel portion and the third panel portion are generally coplanar with the respective second panel portion and fourth panel portion when the carton is in the erect position, and the first side panel and the second side panel are folded along the respective first lateral fold line and second lateral fold line so that the first panel portion generally opposes the second panel portion and the third panel portion generally opposes the fourth panel portion when the carton is in the non-erect position.

15. The reinforced package of claim 14 , wherein the first side panel is foldably connected to the front panel along a first fold line and to the back panel along a second fold line, the second side panel is foldably connected to the front panel along a third fold line and to an attachment flap along a fourth fold line, the attachment flap is at least partially attached to the back panel, and each of the first fold line, the second fold line, the third fold line, and the fourth fold line comprises a first oblique portion extending from a second oblique portion so that each of the front panel and the back panel is widest at respective upper and lower edges.

16. The reinforced package of claim 1 , wherein the first side panel comprises a first panel portion foldably connected to a second panel portion along a first fold line, the first panel portion is foldably connected to the front panel along a second fold line, and the second panel portion is foldably connected to the back panel along a third fold line.

17. The reinforced package of claim 16 , wherein each of the second fold line and the third fold line comprises a first oblique portion extending from a second oblique portion at a vertex, each vertex being spaced apart from the first fold line so that each of the first panel portion and the second panel portion is widest adjacent the respective vertex.

18. The reinforced package of claim 1 , wherein the first gusset panel and the second gusset panel are generally coplanar when the carton is in the erect position and are folded to be at least partially in face-to-face contact with one another when the carton is in the non-erect position.

19. The reinforced package of claim 1 , wherein each of the first bottom panel and the second bottom panel is free from connection to each of the first side panel and the second side panel.

20. The reinforced package of claim 1 , wherein the front panel, the back panel, the first bottom panel, and the second bottom panel at least partially overlap one another when the carton is in the non-erect position.

21. A reinforced package for holding a product, the reinforced package comprisin
