Abstract
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.
Claims20
A tool for forming anti-missile features in a metallic end closure, comprising:
- a body having a first end and a substantially circular shaped second end;
- a flange disposed on said first end of said body, said flange having a larger outer diameter than said body;
- a first shaped feature and a second shaped feature extending from said second end of said body, said first and second shaped features each having a substantially rectangular shape and arranged substantially parallel to each other;
- and
- wherein said first shaped feature comprises a first horizontal offset from an end of said first shaped feature to a plane oriented through a center of said body, and wherein said second shaped feature comprises a second horizontal offset from an end of said second shaped feature to said plane oriented through said center of said body.
A tool for forming anti-missile features in a metallic end closure, comprising:
- an elongated cylindrical body having a first end and a second end;
- a first shaped feature and a second shaped feature extending from said second end of said elongated cylindrical body, said first and second shaped features each having a substantially rectangular shape and aligned in a substantially parallel relationship;
- and
- wherein an end of said first shaped feature is offset from an end of said second shaped feature by a first offset distance, and a longitudinal axis of said first shaped feature is offset from a longitudinal axis of said second shaped feature by a second offset distance.
A tool for forming anti-missile features in a metallic end closure, comprising:
- an elongated cylindrical body having a first end and a second end;
- a first shaped feature and a second shaped feature extending from said second end of said elongated cylindrical body and aligned in a substantially parallel relationship, said first and second shaped features each having a substantially rectangular shape that tapers as each shaped feature extends from said second end of said elongated cylindrical body;
- and
- wherein said first shaped feature comprises a first centerline offset from a center of said first shaped feature to a first plane through a center of said elongated cylindrical body, and wherein said second shaped feature comprises a second centerline offset from a center of said second shaped feature to said first plane through said center of said elongated cylindrical body;
- and
- wherein said first shaped feature comprises a first horizontal offset from an end of said first shaped feature to a second plane through said center of said body, and wherein said second shaped feature comprises a second horizontal offset from an end of said second shaped feature to said second plane through said center of said body.
