It is contemplated that the teachings of the invention can be applied to various containers suitable for carrying a wide variety of articles.

Referring to FIG. 1, there is shown a first blank 10 for forming a carton 90 (see FIGS. 2-3). The blank 10 is formed from a sheet of suitable substrate. It is to be understood that, as used herein, the term “suitable substrate” includes all manner of foldable sheet material such as paperboard, corrugated board, cardboard, plastic, combinations thereof, and the like. It should be recognized that one or other numbers of blanks may be employed, for example, to provide the cartons described in more detail below.

In one or more embodiments, blank 10 can be formed from a paperboard, corrugated board, or cardboard in which one or both sides of the blank, is printed and/or treated with one or more coatings, such as for example, one or more waterproof coatings and/or one or more coatings designed to provide a smooth and/or visually-attractive surface (e.g., a white or other colored surface). In one or more embodiments, informational or promotional material such as, e.g., a brand name or logo, can be printed on a treated side.

Referring to FIG. 1, blank 10 has a first or exterior surface 6 and a second or interior surface 8. Blank 10 includes a plurality of panels hingedly connected together in series that form a tubular structure in the erected carton 90. A glue flap panel 20 is hingedly connected to a rear panel 12 via transverse fold line 11. Rear panel 12 is hingedly connected to a first side panel 14 via transverse fold line 13. First side panel 14 is hingedly connected to a front panel 16 via transverse fold line 15. Front panel 16 is hingedly connected to a second side panel 18 via transverse fold line 17.

A first bottom closure panel 26 is hingedly connected to rear panel 12 along a lower end thereof via longitudinal fold line 23. A first bottom closure flap 32 is hingedly connected to first side panel 14 along a lower end thereof via longitudinal fold line 27.

Oblique fold lines 65, 67 can be formed in respective first and second bottom closure panels 26, 54, defining respective hinged sections 28 and 56. In the illustrated embodiment, bottom closure panels and flaps 26, 32, 54, 60 are configured so as to form an “auto-bottom”-style bottom closure of carton 90 in which a bottom wall 87 of the carton 90 is automatically formed as the carton is erected into a tubular form. In other embodiments, however, other style bottom closures may be used. Bottom wall 87, together with front panel 16, rear panel 12, first side panel 14, and second side panel 18, form an outer tray portion 89 of carton 90.

A top closure panel 22 is hingedly connected to rear panel 12 along an upper end thereof via longitudinal fold line 19. In the illustrated embodiment, longitudinal fold line 19 is interrupted by a plurality of depressible menu tabs 62. A top tuck flap 24 is hingedly connected to top closure panel 22 along an upper end thereof via longitudinal fold line 21. Cut lines 71 and 73 extend from opposite edges of fold line 21 to opposite outer edges of top tuck flap 24. A cut line 69 interrupts fold line 21 and defines a tab 78 that facilitates opening of the carton 90. A first dust flap 30 is hingedly connected to first side panel 14 along an upper edge thereof via longitudinal fold line 25. A second dust flap 58 is hingedly connected to second side panel 18 along an upper edge thereof via longitudinal fold line 33. Top closure panel 22, top tuck flap 24, and first and second dust flaps 30, 58 are configured to form a slit lock tuck-style top closure or lid of carton 90. In other embodiments, however, other style top closures may be used.

Blank 10 includes a fold-in-tray-forming portion 34 that includes a tray front panel 36, tray base panel 38, tray rear panel 40, tray first side panel 42, and tray second side panel 44, as well as first, second, third, and fourth corner gusset panels 46, 48, 50, 52. Tray front panel 36 is hingedly connected to front panel 16 along an upper end thereof via longitudinal fold line 31. In the illustrated embodiment, fold line 31 is interrupted by an aperture 64. A tray base panel 38 is hingedly connected to front tray panel 36 along an upper end thereof via longitudinal fold line 37. A tray rear panel 40 is hingedly connected to tray base panel 38 along an upper end thereof via longitudinal fold line 43. A tray first side panel 42 is hingedly connected to base panel 38 along a first side thereof via transverse fold line 39. A tray second side panel 44 is hingedly connected to base panel 38 along a second side thereof via transverse fold line 41. A first corner gusset panel 46 is disposed between and hingedly connected to tray first side panel 42 and tray front panel 36 along respective fold lines 45 and 43. A second corner gusset panel 48 is disposed between and hingedly connected to tray first side panel 42 and tray rear panel 40 along respective fold lines 47 and 49. A third corner gusset panel 50 is disposed between and hingedly connected to tray rear panel 40 and tray second side panel 44 along respective fold lines 51 and 53. A fourth corner gusset panel 52 is disposed between and hingedly connected to tray second side panel 44 and tray front panel 36 along respective fold lines 55 and 57. Tray front panel 36, tray rear panel 40, tray first side panel 42, tray second side panel 44, and first, second, third, and fourth gusset panels 46, 48, 50, 52 together form a leak-resistant fold-in tray 70 in the erected carton 90 as shown in FIG. 3. Fold-in tray 70 is preferably sized and configured to nest within carton 90 so as to generally conform to outer tray portion 89. Thus, in the erected carton, tray base panel 38 may overlie and rest in a flat, generally face-contacting relationship with carton bottom wall 87; tray front panel 36 may overlie and rest in a flat, generally face-contacting relationship with front panel 16; tray rear panel 40 may overlie and rest in a flat, generally face-contacting relationship with rear panel 12; tray first side panel 42 may overlie and rest in a flat, generally face-contacting relationship with first side panel 14; and tray second side panel 44 may overlie and rest in a flat, generally face-contacting relationship with second side panel 18. It is noted that in the illustrated embodiment, fold-in-tray-forming portion 34 is only attached to the outer-tray-forming portion of blank 10 via the hinged connection (fold line 31) between tray front panel 36 and front panel 16.

Turning to the construction of the carton 90 as illustrated in FIG. 2, the carton 90 is configured so that it can be quickly hand erected from a knocked-down-flat configuration. Blank 10 can be assembled into the knocked-down flat configuration shown in FIG. 4 by adhering glue flap 20 to second side panel 18 to form a collapsed tubular structure and by folding bottom closure panels and flaps 26, 32, 54, 60 to form the carton's auto-erecting bottom closure. To erect the carton 90, a user can move, for example, rear panel 12 relative to front panel 16 until they are substantially aligned with one another in a tubular container structure, resulting in the partially-formed carton shown in FIG. 5. Fold-in tray 70 can then be formed very quickly and essentially “automatically” by simply folding tray front panel 36 inwardly along fold line 31 (as shown in FIG. 6) and “tucking” the components of tray-forming portion 34 into the interior of outer tray portion 89. Fold-in tray 70 is formed automatically via this tucking motion as the fold-in tray components are brought into contact with, and folded by so as to generally contour to, their counterparts. This results in the erected carton 90 with open top closure as shown in FIG. 70. Dust flaps 30, 58, top closure panel 22, and top tuck flap 24 can be folded inwardly along their respective fold lines to close the carton's top, resulting in the closed carton 90 shown in FIG. 2.

The configuration of the disclosed blank 10 and carton 90 may provide certain advantages over cartons. In particular, the blank 10 is straightforward and inexpensive to manufacture. The carton 90 can be shipped in a knocked-down-flat configuration and then quickly and easily erected on site. The fold-in tray 34 provides a leak-resistant barrier that is integrally formed with the container and thus reliably positioned within the outer tray. In addition, carton 90 may provide enhanced thermal retention properties. As yet another potential advantage, the effectively 2-ply nature of the carton bottom created by the overlap of the tray base and carton bottom wall may significantly reduce the issue of grease wicking. This may reduce the issue of oil stains and enable the carton to be manufactured without a coating/barrier, thereby reducing the cost of manufacture and enhancing the recyclability/compostability of the carton.

Exemplary embodiments of blanks and methods for forming containers are described above in detail. The apparatus and methods are not limited to the specific embodiments described herein, but rather, components of apparatus and/or steps of the methods may be utilized independently and separately from other components and/or steps described herein. For example, in the illustrated embodiment, fold-in-tray-forming portion 34 is hingedly connected to the remainder of the blank 10 along an upper edge of front panel 16. In other embodiments, however, a fold-in-tray-forming portion can be hingedly connected to the remainder of the blank 10 along an upper edge of the rear panel, first side panel, or second side panel.

Although specific features of various embodiments of the invention may be shown in some drawings and not in others, this is for convenience only. In accordance with the principles of the invention, any feature of a drawing may be referenced and/or claimed in combination with any feature of any other drawing.
