A metallic container end closure is provided that generally comprises a primary pour opening and an extended or secondary score which is opened with a secondary tool to form a secondary pour opening. The fact that a secondary tool is required allows the secondary score to be shallower, and thus more secure than deeper scores that are openable by finger pressure alone. Once the secondary tool is used to fracture the secondary score, a secondary pour opening is produced adjacent to the primary pour opening to form a larger opening. A user may insert materials such as ice or oranges through the enlarged pour opening.

1. A container end closure with a peripheral curl adapted for interconnection to a neck of a container, comprising: a central panel having a rivet interconnecting a pull tab to an upper surface of said central panel, said pull tab adapted for applying a downward force;a primary tear panel disposed on said central panel, said primary tear panel at least partially defined by a primary score extending from a starting point to a termination point and by a first hinge, said primary score configured to be sheared by said downward force of said pull tab to deflect said primary tear panel about said first hinge and create a primary pour opening; anda secondary tear panel disposed on said central panel, said secondary tear panel at least partially defined by a secondary score extending from a starting point to a termination point and by a second hinge, said secondary score located proximate to said primary score, said secondary tear panel configured to be sheared by a downward force generated by a secondary tool to deflect said secondary tear panel about said second hinge and create a secondary pour opening, wherein said primary pour opening and said secondary pour opening are positioned adjacent to form a contiguous pour opening area to enhance pour characteristics and selectively allow insertion of additional materials. 2. The container end closure of claim 1, wherein a nose of said pull tab is rotatable about said rivet to define an area of engagement about said rivet, wherein at least a portion of said primary tear panel is positioned in said area of engagement, and said secondary tear panel is positioned outside of said area of engagement. 3. The container end closure of claim 1, wherein said secondary tear panel is at least partially defined by said primary score and a transition portion between a deboss area of said central panel and a non-deboss area of said central panel, wherein at least a portion of said transition portion is said second hinge. 4. The container end closure of claim 1, wherein said secondary score forms an arc having a predetermined radius. 5. The container end closure of claim 4, wherein said radius of said arc is between approximately 0.01 and 1.0 inches. 6. The container end closure of claim 1, wherein said contiguous pour area covers between approximately 10% and 33% of an area of said central panel. 7. The container end closure of claim 1, wherein said end closure comprises at least two secondary pour openings positioned proximate to said primary pour opening. 8. The container end closure of claim 1, further comprising: a transition zone positioned between said termination point of said primary score and said starting point of said secondary score, wherein said transition zone is an uninterrupted portion of said central panel. 9. The container end closure of claim 1, further comprising: a protrusion positioned proximate to said secondary score, said protrusion configured to receive a portion of said secondary tool to provide the downward force on said secondary tear panel. 10. The container end closure of claim 1, further comprising: a depression positioned proximate to said secondary score, said depression configured to receive a portion of said secondary tool to provide said downward force on said secondary tear panel. 11. A method of forming a primary pour opening and an adjacent secondary pour opening in a metallic end closure to enhance pour characteristics, comprising: providing said metallic end closure adapted for interconnection to a neck of a container, comprising: a central panel with a peripheral curl on a perimeter edge, a pull tab for applying a first downward force on a primary tear panel interconnected to said central panel, and said primary tear panel at least partially defined by a primary score;a secondary tear panel positioned adjacent to said primary tear panel, said secondary tear panel at least partially defined by a secondary score;lifting a tail end of said pull tab to apply said first downward force on said primary tear panel to shear said primary score, deflect said primary tear panel about a first hinge, and create said primary pour opening in said metallic end closure;providing a secondary tool for applying a second downward force on said secondary tear panel; andengaging said secondary tool with said secondary tear panel to apply said second downward force on said secondary tear panel to shear said secondary score, deflect said secondary tear panel about a second hinge, and create said secondary pour opening in said metallic end closure. 12. The method of claim 11, further comprising: rotating a nose of said pull tab about a rivet to define an area of engagement about said rivet, wherein at least a portion of said primary tear panel is positioned in said area of engagement, and said secondary tear panel is positioned outside of said area of engagement. 13. The method of claim 11, wherein said secondary tear panel is at least partially defined by said primary score and a transition portion between a deboss area of said central panel and a non-deboss area of said central panel. 14. The method of claim 13, wherein when said secondary tool engages said secondary tear panel to shear said secondary score, said secondary tear panel is deflected about said transition portion, wherein at least a portion of said transition portion is said second hinge. 15. The method of claim 11, wherein said secondary score is at least partially defined by an arc having a predetermined radius. 16. The method of claim 15, wherein said radius of said arc is between approximately 0.01 and 1.0 inches. 17. The method of claim 11, further comprising: providing a transition zone positioned between one end of said primary score and one end of said secondary score, wherein when said secondary tool engages said secondary tear panel, said second downward force shears said transition zone. 18. The method of claim 17, wherein said transition zone is an uninterrupted portion of said central panel. 19. A container end closure with a peripheral curl adapted for interconnection to a neck of a container, comprising: a central panel having a rivet interconnecting a pull tab to an upper surface of said central panel, said pull tab adapted for applying a downward force, wherein a nose of said pull tab is rotatable about said rivet to define an area of engagement about said rivet;a primary tear panel disposed on said central panel, said primary tear panel at least partially defined by a primary score extending from a starting point to a termination point and by a first hinge, wherein at least a portion of said primary tear panel is positioned in said area of engagement, said primary score configured to be sheared by said downward force of said pull tab to deflect said primary tear panel about said first hinge and create a primary pour opening;a secondary tear panel disposed on said central panel, said secondary tear panel at least partially defined by a secondary score extending from a starting point to a termination point, said primary score, and a transition portion between a deboss area of said central panel and a non-deboss area of said central panel, wherein said secondary tear panel is positioned outside of said area of engagement, said secondary tear panel configured to be sheared by a downward force generated by a secondary tool to deflect said secondary tear panel about at least a portion of said transition portion that forms a second hinge with said central panel and create a secondary pour opening;a transition zone positioned between said termination point of said primary score and said starting point of said secondary score, wherein said transition zone is an uninterrupted portion of said central panel; andwherein said primary pour opening and said secondary pour opening combine to form a contiguous pour opening area to enhance pour characteristics and selectively allow insertion of additional materials into said container.
