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.
Claims8
Feeding device for pre-sterilized objects contained in internally sterile receptacles, for sterile packing plants, comprising:
- a chamber (1) provided with two apertures, the first aperture (2) of which, connects, through an opening and closing mechanism operated from outside said chamber, the chamber itself with a sterile environment (5), and the second aperture (3) of which, is shaped in such a way that the mouth (10b) of a receptacle (10) containing the pre-sterilized objects enters it, blocking it completely;
- a first means for creating a sterile gas atmosphere within the chamber at a pressure slightly higher than atmospheric pressure;
- a locking means for securing said receptacle in the position in which its mouth occupies said second aperture;
- a second means operated from outside said chamber, for removing a lid (10b) of said receptacle when the latter is locked by said locking means;
- a diaphragm inserted between said first and second aperture, for greatly reducing the sectional area of flow of the gas contained in the chamber towards the outside, when said second aperture is free.
