In the method according to the invention for functionalizing a plastic container (1), the container (1) being bounded externally by a double wall (2) which consists of an inner wall (4) forming an internal space (3) of the container (1) and an outer wall (5) surrounding the former, an intermediate space (6) being formed between the inner wall (4) and the outer wall (5), a reactive gas comprising at least one of the following reactive substances:
a. fluorine; and
b. chlorine
is fed for at least a predeterminable treatment time (8) into the internal space (3), which is subsequently flushed for at least a predeterminable flushing time (7, 9) with a flushing gas free of reactive substances. The method according to the invention for functionalizing a plastic container (1) even makes it possible to functionalize containers (1) with very large volumes, which otherwise could not be functionalized or could be functionalized only with great difficulty. In particular, the method according to the invention is suitable for functionalizing containers (1) which have a volume of more than 1 m 3 and up to 60 m 3 or more. These sizes refer to the volume of the internal space (3). Such containers (1) are particularly preferably used for holding and storing chemicals, in particular acids or bases. |
