摘要

Producing a shell-shaped, homogeneous and laminar flow from an ink composition, is claimed, where the flow is carried out by pumping the ink composition through an interior of a double walled tube on which a ring is coated on its upper side. Independent claims are included for: (1) an ink cartridge in which one or more of double-walled pipes are placed; and (2) applying a coating for candles (3), comprising slightly immersing a bottom of the candle into the shell-shaped, homogeneous, laminar flow of the ink composition in a double-walled tube (7).
