Abstract

Viscous compositions are metered discontinuously into storage vessels such as tubes, tubs, or cartridges, from a stable volume container free of dead space wherein the calculated volume, expressed as the mathematical product of adiabatic compressibility coefficients of the composition, the outlet pressure, and volume of the container exceed the metered volume.
