Abstract
An apparatus for sterilizing containers, such as beakers, on a line of an aseptic food packaging machine has a sintered stainless steel tube (6) surrounded by an outer tube (7) which has a plurality of outlets (10). A source of hydrogen peroxide (H.sub.2 O.sub.2) (1) is vaporized by heated air (4) and passed into the sintered tube (6), from where it permeates to the outer tube (7) and via the outlets (10) to respective containers (18), to sterilize the containers. The combination of the sintered tube and outer tube serves to evenly distribute the H.sub.2 O.sub.2 vapor to evenly sterilize a row or beakers, indexed through the apparatus.
