Abstract: The invention concerns a feeding device for pre-sterilized objects contained in internally sterile receptacles, for sterile packing plants. The device substantially comprises a chamber within which a sterile atmosphere is created at a pressure slightly higher than the atmospheric pressure, which communicates, by means of a valve-operated aperture, with a sterile environment into which the objects are to be transferred. The receptacle containing the objects is secured in correspondence with a second aperture in the chamber, a sterile atmosphere is created within the chamber and the lid of the receptacle is removed mechanically. The objects drop to the bottom of the chamber and by acting upon the valve, are transferred to the sterile environment.
