END CLOSURE WITH DOUBLE ANTI-MISSILE SCORE |
摘要 |
An end closure for food and beverage containers provides controlled opening characteristics to prevent the unintentional missiling of a tear panel. The end closure comprises a score line that defines a portion of the tear panel, and the end closure may comprise one or more anti-missile features that inhibit the propagation of a fracture down a score line, which reduces the likelihood that a tear panel will inadvertently detach from the end closure and injure the user or another. |

1. A metallic end closure with controlled opening characteristics, comprising:
a peripheral curl which is adapted for interconnection to a neck of a container body; a central panel; a countersink positioned between said peripheral curl and said central panel; a pull tab having a nose end and a tail end, wherein said pull tab is operably interconnected to said central panel; a first score line in said central panel which defines a tear panel; and at least one anti-missile feature positioned proximate to said first score line which deforms at least a portion of said first score line to affect the rate at which said tear panel opens along said first score line when a user pivots said nose end of said pull tab into said tear panel. |
