Abstract

A fully enclosed carton for carrying heavy loads with a reinforcement insert for the handle apertures located in the top end flaps of the carton. The paperboard reinforcing insert may be extended as a bridge across the top panel of the carton to prevent tearing of the handle apertures in the top end flaps and also tearing in the top panel of the carton when carrying a heavy load. The carton may have one or more dispensers in the top panel which may extend into an adjoining side panel. Multiple tear lines may be formed for the dispenser flap in the insert that extends across the top panel to permit easy access to the containers, such as bottles, in the carton. The paperboard reinforcing insert may have a larger aperture than the handle aperture in each top end flap to adjust for any imprecision in the alignment of the paperboard insert in forming the carton sleeve from the paperboard blank. When the paperboard insert extends across the top panel and one or more dispensers are formed in the top panel, multiple tear lines may be used to form the flaps in the insert to compensate for any imprecision in the insertion of the insert that extends across the top panel into the carton sleeve when it is being formed.

First claim

What is claimed is:

1. A method of forming a carton comprising:
providing a carton blank comprising (1) a top panel having a first side edge, a second side edge, and end edges, a first side panel and a second side panel each having a first side edge, a second side edge, and end edges, the first side edge of the first side panel being connected at the first side edge of the top panel, the first side edge of the second side panel being connected at the second side edge of the top panel, and a bottom panel connected to the second side edge of the second side panel; (2) top end flaps including a first top end flap and a second top end flap, the first top end flap being connected to one of the end edges of the top panel along a first top end fold line; (3) a handle aperture through at least one of said top end flaps; (4) side panel end flaps, including a first side panel end flap connected to one of the end edges of the first side panel and a second side panel end flap connected to one of the end edges of the second side panel, the first side panel end flap and the second side panel end flap each having a side panel end flap aperture that corresponds to said handle aperture and positioned to be in substantial alignment with said handle aperture when the carton is formed; and (5) a finger flap located in the top panel; and
providing an insert that is devoid of foldable connection to the carton blank, the insert having at least one insert aperture and being securable to at least one of the first top end flap, the second top end flap, and the top panel in such a position that, when the carton is formed from said carton blank, (1) the insert aperture will be in sufficient alignment with the handle aperture and the side panel end flap apertures (i) to reinforce the handle aperture, and (ii) to allow a person's hand to be extended through the handle aperture, the side panel end flap aperture, and the insert aperture; (2) the insert is devoid of overlapping contact with at least one of the first side panel and the second side panel; and (3) the insert is positioned between the first top end flap and the first side panel end flap such that the insert, the first top end flap, and the first side panel end flap form three at least partially overlapping layers between the first top end fold line and the handle aperture; wherein the insert includes a finger aperture located to be sufficiently aligned with the finger flap in the top panel to permit the finger flap to be pushed into the finger aperture; wherein the first side panel and the second side panel are foldably connected to the top panel at opposite sides of the top panel;
attaching the bottom panel to the second side panel to form a sleeve; and
securing the insert, after providing the insert, to at least one of the first top end flap and the second top end flap in a position where the at least one insert aperture is sufficiently aligned with the handle aperture (i) to reinforce the handle aperture and (ii) to allow a person's hand to be extended through the handle aperture and the at least one insert aperture.

2. The method of claim 1 , wherein the insert is secured to the inside of the sleeve.

3. The method of claim 1 , wherein the securing the insert comprises securing the insert to each of the first top end flap and the second top end flap, in a position so that the insert apertures are sufficiently aligned with the handle apertures (i) to reinforce the handle apertures and (ii) to allow a person's hand to be extended through either handle aperture and the insert aperture aligned therewith.

4. The method of claim 3 , wherein the insert comprises a first insert and a second insert that is devoid of connection to the first insert, and wherein the securing the insert comprises securing the first insert to the first top end flap and securing the second insert to the second top end flap.

5. The method of claim 3 , wherein the insert is monolithic, has two handle apertures, and is secured to the first top end flap, the second top end flap and the top panel.

6. The method of claim 1 , wherein the first side panel is foldably connected to the top panel along a first fold line, the top panel is foldably connected to the second side panel along a second fold line, and the bottom panel is foldably connected to the second side panel along a third fold line.

7. The method of claim 1 , wherein the insert, the first top end flap, and the first side panel end flap form three at least partially overlapping layers above the handle aperture.

8. A method of forming a carton, comprising:
providing a blank comprising a plurality of panels, the plurality of panels comprising a top panel, a bottom panel, and at least one side panel, the blank comprising a plurality of end flaps including at least one top end flap and at least one side end flap, the at least one top end flap and the at least one side end flap each having a handle aperture;
providing an insert comprising a handle aperture, the insert devoid of foldable connection to the blank;
folding the plurality of panels at least partially around an interior of the carton such that the handle aperture of the at least one top end flap and the at least one side end flap are aligned; and
securing the insert, after providing the insert, to at least one of the at least one top end flap and the top panel such that the insert is positioned between the at least one top end flap and the at least one side panel to form at least three at least partially overlapping layers between the handle aperture of the at least one top end flap and an end edge of the top panel, the handle aperture of the insert aligns with a respective handle aperture of each of the at least one top end flap and the at least one side end flap.

9. The method of claim 8 , wherein the insert is positioned between the at least one top end flap and the at least one side panel.

10. The method of claim 8 , wherein the insert comprises a finger flap.

11. The method of claim 10 , wherein, when the insert is secured to at least one of the at least one top end flap and the top panel, the finger aperture aligns with the finger flap.

12. The method of claim 8 , wherein each of the top panel and the at least one side panel comprise a first side edge, a second side edge, and end edges, and the at least one side panel comprises a first side panel and a second side panel.

13. The method of claim 12 , wherein the insert is free from overlapping contact with at least one of the first side panel and the second side panel.

14. The method of claim 12 , wherein the first side edge of the first side panel is connected to the first side edge of the top panel.

15. The method of claim 14 , wherein the first side edge of the second side panel is connected to the second side edge of the top panel.

16. The method of claim 14 , wherein the bottom panel is connected to the second side edge of the second side panel.

17. The method of claim 8 , wherein the insert, the at least one top end flap, and the at least one side panel end flap form at least three at least partially overlapping layers above the handle aperture of the at least one top end flap.
