Abstract: A process for coating inside a container includes rotating the container about its imaginary vertical axis while simultaneously lowering airless spray nozzles along the vertical axis of the container into the cavity through the opening end and moving the nozzles back up and out of the container. Spray nozzles are used to apply a liquid coating at a spray pressure of about 100 to about 800 psi (6.89 to 55.16 bar) and at an angle of about 0 to about 120 degrees relative to the vertical axis, simultaneously with nozzle movement, to at least a portion of the inner surface while the container is rotating and the nozzles are moving along the vertical axis. The container is thereby coated on its inner surface to form an internally coated container.
