Claim:
1. An adaptor for coupling with a medical container having a collar closed by a septum, said septum having an outer surface directed towards an outside of the medical container, the adaptor comprising: a tubular body substantially closed at a distal end with a transversal wall provided with a central hole and substantially closed at a proximal end by a pierceable elastomeric piece, said pierceable elastomeric piece defining a distal plug at a distal end thereof, said pierceable elastomeric piece, transversal wall and tubular body together defining an inner cavity of said adaptor, said pierceable elastomeric piece being movable within said tubular body between a first position, in which said distal plug is seated within and forms a seal with said central hole, and a second position, in which the distal plug is proximally spaced from said first position, in which said distal plug is displaced from said central hole, an air inlet for allowing air from the outside to enter said inner cavity at least when said pierceable elastomeric piece moves from the first position to the second position, said air inlet comprising a filtering system for decontaminating said entering air before it reaches said inner cavity, and a gripping member for securing the adaptor to the medical container, so that a distal surface of said transversal wall is brought in contact with the outer surface of said septum when said adaptor is secured on said medical container.
