Although similar to the existing 55mm cap supplied to Heinz for the smaller Top Down Ketchup bottles, the 63mm cap has been designed specifically for the new bottles to maximise valve performance.
A key project element has been the development of a new valve sub-assembly to meet increasing market demand for large volume products. This is used in the 55mm and 63mm closures, both of which are embossed with the "Heinz 57 varieties" legend.
