Abstract

Cartons include liquid-tight vessels that line the interior volumes of the cartons. The cartons may have selected sections reinforced by one or more reinforcing blanks.

Claims

a bottom closure;

a first side panel;

a second side panel;

a first end panel;

a second end panel, wherein the side and end panels and the bottom closure define in part an interior volume of the carton; and

a liquid-tight vessel attached to at least a portion of the interior surface and lining at least a portion of the interior volume of the carton.

2. The carton of claim 1, wherein the bottom closure comprises a plurality of bottom flaps.

3. The carton of claim 1, wherein the carton is constructed from a major blank and at least one minor blank adhered to the major blank.

4. The carton of claim 3, wherein the vessel is adhered to the at least one minor blank.

5. The carton of claim 3, wherein the at least one minor blank is adhered to at least two of the first side panel, the second side panel, the first end panel, and the second end panel.

6. The carton of claim 1, further comprising a top closure.

7. The carton of claim 6, wherein the carton is constructed from a major blank and at least one minor blank adhered to the major blank between the bottom and top closures.

8. The carton of claim 6, wherein the top closure comprises:

a first side top flap; and

a second side top flap.

9. The carton of claim 6, wherein the vessel is adhered to the interior surface adjacent to the top closure.

10. The carton of claim 1, further comprising a tear strip, the tear strip at least partially defining a lid in the carton.

11. The carton of claim 10, wherein the tear strip extends around a periphery of the carton so that the lid is removable.

12. The carton of claim 10, wherein the tear strip extends around a part of the periphery of the carton so that the lid is pivotable.

13. The carton of claim 1, wherein the carton is parallelepipedal.

14. The carton of claim 1, further comprising at least one handle.

15. A multi-ply carton constructed from a major blank and at least one minor blank and having an interior surface, comprising:

a bottom closure;

a first side panel;

a second side panel;

a first end panel;

a second end panel, wherein the side and end panels and the bottom closure define in part an interior volume of the carton; and

a liquid-tight vessel attached to at least a portion of the interior surface and lining at least a portion of the interior volume of the carton, wherein

the minor blank is adhered to at least two of the first side panel, the second side panel, the first end panel, and the second end panel.

16. The carton of claim 15, further comprising a top closure.

17. The carton of claim 16, wherein the at least one minor blank comprises an upper minor blank adhered to the major blank adjacent to the top closure.

18. The carton of claim 17, wherein the at least one minor blank further comprises a lower minor blank adhered to the major blank at the bottom closure.

19. The carton of claim 16, wherein the at least one minor blank is adhered to the major blank between the bottom and top closures.

20. The carton of claim 16, wherein the top closure comprises:

a first side top flap; and

a second side top flap.

21. The carton of claim 16, wherein the vessel is adhered to the interior surface adjacent to the top closure.

22. The carton of claim 15, wherein the at least one minor blank comprises a lower minor blank adhered to the major blank at the bottom closure.

23. The carton of claim 15, wherein the bottom closure comprises a plurality of bottom flaps.

24. The carton of claim 23, wherein the plurality of bottom flaps comprises:

a first side bottom flap; and

a second side bottom flap.

25. The carton of claim 15, further comprising a tear strip.

26. The carton of claim 15, wherein the carton is parallelepipedal.

27. An article, comprising:

a blank, the blank comprising;

at least one bottom flap;

at least one top flap;

a first side panel;

a second side panel;

a first end panel; and

a second end panel; and

a liquid-tight vessel adhered to at least a portion of an interior surface of the blank.

29. The article of claim 27, wherein the article has a flat tubular form with the vessel located in an interior of the flat tubular form.

30. The article of claim 29, wherein one of the end panels is glued adjacent to one of the side panels.

31. The article of claim 27, wherein the side panels are substantially rectangular.

32. The article of claim 27, wherein the blank is a multi-ply blank comprising at least a major blank and at least one minor blank adhered to the major blank, the first side panel, the second side panel, the first end panel, and the second end panel comprising sections of the major blank.

33. The article of claim 32, wherein the minor blank is adhered to at least two of the first side panel, the second side panel, the first end panel, and the second end panel.

34. The article of claim 32, wherein the at least one minor blank comprises an upper minor blank adhered to the major blank adjacent to the at least one top flap.

35. The article of claim 32, wherein the at least one minor blank comprises a lower minor blank adhered to the major blank at the at least one bottom flap.

36. The article of claim 32, wherein at least one minor blank is adhered to the major blank between the at least one bottom flap and the at least one top flap.

37. A method of utilizing a multi-ply carton constructed from a major blank and at least one minor blank and having an interior surface, the method comprising:

providing a carton, comprising;

a bottom closure;

a top closure;

a first side panel;
