For the prevention of contamination of a vial (2) with traces of medicinal fluids, for exam- ple cytostatics and antibiotics, which may be spilt on the outside of the vial (2) while filling, the vial (2) is provided with a tight-fitting protective envelope (6) as a last step in the production process. The envelope (6) comprises a bottom sticker (602) which is attached to a bottom (202) of the vial (2) and a tight-fitting sleeve (601), which is shrunk on a side wall (201) of the vial (2), while partly overlapping the bottom sticker (602) along a circumferential edge of the bottom (202) of the vial (2) As a result of the arrangement of the envelope (6), a possible contamination which remains on the outside of the vial (2) is encapsulated between the vial (2) and the envelope (6). Consequently, a user is no longer exposed to toxic substances, because the user will not touch the vial (2) itself, but will touch the envelope (6).
