ABSTRACT:
The invention generally relates to a closure having a cap coupled to a sleeve defining a frangible connection between the cap and the sleeve. A preselected geometry is provided between the cap and the sleeve proximate to the frangible connection which allows for formation of a clean break between the cap and the sleeve when the cap is broken away from the sleeve. An extended bead is also provided with consistent material distribution on the bead proximate to a juncture of the cap to the sleeve after the cap is broken away from the sleeve. A projection is additionally provided on the cap which projects at an angle. The projection has a generally tapering leg of reduced thickness that terminates in a vertical wall segment. The projection also has the bead that is formed located on an outer corner of the projection after the frangible connection is broken.
