ABSTRACT:
This relates to the special construction of shells for closure panels of composite closures which, in production, for all practical purposes will eliminate nesting of stacked closure panels. Most specifically, each closure panel will be provided with flutes indenting the skirts thereof so as to prevent closure panels from nesting when stacked. Preferably, each closure panel is provided with at least three flutes and preferably four with the circumferential spacing of the flutes of a closure panel all being different and when the shells of the closure panels are formed in a multiple cavity die, the flute arrangement in each cavity will also be different. This will, for all practical purposes, eliminate nesting of the closure panels when stacked during production.
