Abstract

A carton includes an outer shell ( 102 ) defining an interior space with upper and lower tiers. A divider ( 120 ) is disposed at least in part in the outer shell dividing between the upper and lower tiers. A tear strip ( 118 ) defined in the outer shell operatively connecting an upper portion of the outer shell to a lower portion thereof. The upper portion defines a six-sided structure, a bottom side of which includes the divider. The upper portion is configured to be removed from the lower portion by lifting the upper portion after the tear strip is activated.

Claims (27)

1. A carton comprising:

an outer shell defining an interior space with upper and lower tiers;

a divider disposed at least in part in the outer shell dividing between the upper and lower tiers; and

a tear strip defined in the outer shell operatively connecting an upper portion of the outer shell to a lower portion thereof, wherein the upper portion defines a six-sided structure, a bottom side of which includes the divider, the upper portion including a handle wherein the upper portion is configured to be removed from the lower portion by lifting the upper portion by the handle after the tear strip is activated,

wherein opposed side end flaps of the outer shell are disposed between a bottom end flap of the divider and a pair of opposed side end flaps of the divider.

2. A carton as recited in claim 1 , wherein the bottom end flap of the divider is adhered to outside surfaces of the side end flaps of the outer shell.

3. A carton as recited in claim 2 , wherein the bottom end flap of the divider is not adhered directly to the side end flaps of the divider.

4. A carton as recited in claim 2 , wherein the bottom end flap of the divider is adhered directly to the side end flaps of the divider.

5. A carton as recited in claim 2 , wherein the bottom end flap of the divider is adhered directly to the side end flaps of the divider through a respective window defined through each respective side end flap of the outer shell.

6. A carton as recited in claim 1 , wherein the side end flaps of the outer shell, the side end flaps of the divider, the bottom end flap of the divider, and a top end flap of the outer shell are all secured together along a single line of adhesive.

7. A carton as recited in claim 6 , wherein the line of adhesive joins the top end flap to the side end flaps of the divider through a respective window defined through each side end flap of the outer shell.

8. A carton as recited in claim 6 , wherein the line of adhesive joins an inner surface of the top end flap to an outer surface of the bottom end flap of the divider.

9. A carton as recited in claim 6 , wherein the line of adhesive joins an inner surface of the top end flap to an outer surface of each side end flap of the outer shell.

10. A carton as recited in claim 1 , wherein the tear strip is disposed below the divider so activation of the tear strip allows removal of the upper portion of the outer shell such that the upper portion can be removed as a separate six-sided container leaving the lower portion with an open top.

11. A carton as recited in claim 1 , wherein the divider includes a handle portion operatively connected to the handle of the outer shell for handle reinforcement.

12. A method of forming a carton comprising:

providing an outer shell defining an interior space with upper and lower tiers; and

securing a divider to the outer shell to divide between the upper and lower tiers, wherein a tear strip operatively connects between an upper portion and a lower portion of the outer shell, the upper portion including a handle wherein the upper portion is configured to be removed from the lower portion by lifting the upper portion by the handle after the tear strip is activated;

wherein the securing step comprises securing side end flaps of the outer shell between a bottom end flap of the divider and a pair of opposed side end flaps of the divider.

13. A method as recited in claim 12 , wherein the step of securing the side end flaps of the outer shell includes adhering so that a top end flap of the outer shell is adhered to the end flaps of the outer shell as well as to an outer surfaces of the bottom end flap of the divider.

14. A method as recited in claim 12 , wherein the step of securing the side end flaps of the outer shell includes adhering so that the bottom end flap of the divider is adhered directly to an outside surface of the side end flaps of the outer shell.

15. A method as recited in claim 13 , wherein the step of securing the side end flaps of the outer shell includes adhering so that the bottom end flap of the divider is not adhered directly to the side end flaps of the divider.

16. A method as recited in claim 14 , wherein the step of securing the side end flaps of the outer shell includes adhering so that the bottom end flap of the divider is adhered directly to the side end flaps of the divider through a respective window defined through each respective side end flap of the outer shell.

17. A method as recited in claim 12 , wherein the step of securing the side end flaps of the outer shell includes adhering so that the side end flaps of the outer shell, the side end flaps of the divider, the bottom end flap of the divider, and a top end flap of the outer shell are all secured together along a single line of adhesive.

18. A method as recited in claim 17 , wherein the step of securing the side end flaps of the outer shell includes adhering so that the line of adhesive joins the top end flap to the side end flaps of the divider through a respective window defined through each side end flap of the outer shell.

19. A method as recited in claim 17 , wherein the step of securing the side end flaps of the outer shell includes adhering so that the line of adhesive joins an inner surface of the top end flap to an outer surface of the bottom end flap of the divider.

20. A method as recited in claim 17 , wherein the step of securing the side end flaps of the outer shell includes adhering so that the line of adhesive joins an inner surface of the top end flap to an outer surface of each side end flap of the outer shell.
