Abstract:
A method for the substantially complete removal of particulates from a container for subsequent use of the container in containing liquids for use in a medical application, said container having a neck region of reduced diameter adjacent an open aperture, said method comprising the steps of:a. inverting the container whereby said open aperture faces downward; b. introducing a pressurized fluid into said container through said aperture to wash and remove particulates from the interior of said container; and c. forming and maintaining said fluid in a moving film on the interior surface of the container whereby re-deposit of particulates from the interior surface of the container, adjacent said aperture, is substancially prevented, wherein sad fluid is formed and maintained as said moving film by serparately but simultaneously directing an inert pressurized gas with said fluid into said container, with the pressure of the fluid and the pressure of the gas being sufficient to form said moving film, and with said moving film being maintained at least until substantial removal of the particulates from the container.
