Method and apparatus for lining container closures

Claim 1

THE METHOD OF LINING CONTAINER CLOSURES WITH CONTAINER LINING COMPOUNDS WHICH, IN A STATE OF REST, EXHIBIT INTRACTABLE VISCOSITY WHICH INCLUDES FORCING THE COMPOUND BETWEEN SPACED, COAXIAL, CYLINDRICAL SURFACES, EXERTING AN ESSENTIALLY UNIDIRECTIONAL FORCE UPON THE COMPOUND BY ROTATING ONE OF THE SURFACES TO IMPART A MEAN SHEAR RATE LYING BETWEEN 200 AND 10000 RECIPROCAL SECONDS, THE SPACING BETWEEN THE CYLINDRICAL SURFACES BEING SUCH AS TO SUBJECT ALL INCREMENTS OF COMPOUND PASSING THROUGH THE DEVICE TO SHEAR RATES LYING WITHIN + OR - 5% OF THE MEAN SHEAR RAE VALUE THEREBY TO PRODUCE A COMPOUND HAVING TEMPORARILY REDUCED VISCOSITY AND SMOOTH-FLOWING CHARACTERISTICS, AND, THEREAFTER, DISCHARGING THE INVENTORY OF SHEARED COMPOND ON SUCCESSIVE CONTAINER CLOSURES AT SUCH A RATE THAT THE INCREMENTAL INVENTORIES OF COMPOUND HAVING LOWERED VISCOSITY ARE PLACED ON THE CLOSURE BEFORE ANY SIGNIFICANT RESTORATION OF THE VISCOSITY OF THE COMPOUND TAKES PLACE.

Claim 2

THE METHOD OF LINING CONTAINER CLOSURES WITH CONTAINER LINING COMPOUNDS WHICH, IN A STATE OF REST, EXHIBIT INTRACTABLE VISCOSITY WHICH INCLUDES FORCING THE COMPOUND BETWEEN SPACED, COAXIAL, CYLINDRICAL SURFACES, EXERTING AN ESSENTIALLY UNIDIRECTIONAL FORCE UPON THE COMPOUND BY ROTATING ONE OF THE SURFACES TO IMPART A MEAN SHEAR RATE LYING BETWEEN 200 AND 10000 RECIPROCAL SECONDS, THE SPACING BETWEEN THE CYLINDRICAL SURFACES BEING SUCH AS TO SUBJECT ALL INCREMENTS OF COMPOUND PASSING THROUGH THE DEVICE TO SHEAR RATES LYING WITHIN + OR - 5% OF THE MEAN SHEAR RAE VALUE THEREBY TO PRODUCE A COMPOUND HAVING TEMPORARILY REDUCED VISCOSITY AND SMOOTH-FLOWING CHARACTERISTICS, AND, THEREAFTER, DISCHARGING THE INVENTORY OF SHEARED COMPOND ON SUCCESSIVE CONTAINER CLOSURES AT SUCH A RATE THAT THE INCREMENTAL INVENTORIES OF COMPOUND HAVING LOWERED VISCOSITY ARE PLACED ON THE CLOSURE BEFORE ANY SIGNIFICANT RESTORATION OF THE VISCOSITY OF THE COMPOUND TAKES PLACE.
