Abstract (en)
[origin: EP0419261A1] The application describes a method of introducing into a container a suspension or solution of a material in a propellant held under pressure, in particular a pharmaceutical material. The method comprises the steps of bringing a filling head (28) into communication with the container (C); introducing a quantity of such suspension or solution into the container through the filling head (28); introducing a quantity of high pressure propellant without any of the said material into the filling head (28), thereby to flush through any suspension or solution remaining in the filling head; and withdrawing the filling head from the container. An apparatus and a filling head (28) for carrying out the method are also described.
