A transfer set for transferring a fluid between a first container (1) containing a fluid and a second container (2), said transfer set comprising:
- a mobile piercing member (8) with a first end (7) and a second end (16);
- a first transfer body (3) comprising a first end (4) and a second end, said first end (4) configured to be connected to said first container (1),
- said first transfer body (3) further comprising a first central passage (6) accommodating at least the first end (7) of the mobile piercing member (8),
- said first end (4) of the first transfer body (3)) comprising i) a boring element, and ii) a first sealing member (9), the first sealing member (9) configured to prevent the fluid communication between said first container (1) and said first transfer body (3),
- said first end (7) of the mobile piercing member configured to be accommodated into said central passage (6) away from said first sealing member (9) so that said first sealing member (9) is non-bored into an inactivated position of said transfer set;
- a second transfer body (13) comprising a first end and a second end, said first end of the second transfer body (13) having a fastening member (14) to receive and fix said second container (2), said second container being closed by a second sealing member,
- said second transfer body (13) further comprising a second central passage (15) accommodating at least the second end of said mobile piercing member (8),
- said second end (16) of the mobile piercing member comprising a boring element,
- said first and second central passages (6, 15) being coaxial,
- the second central passage (15) opening into said fastening member (14) to allow said second end of the mobile piercing member to pass towards the second sealing member, said second end of the mobile piercing member being configured to be provided into said second passage (15) apart from said second sealing member so that said second sealing member is non-bored into an inactivated position of said transfer set,
- wherein at least a part of said second transfer body (13) is a moveable part movable along a moving axis (21) from an inactivated position of the transfer set wherein said moveable part of said second transfer body (13) is partially inserted within the second end of said first transfer body (3) to an activated position of the transfer set wherein a fluid communication between said first and second containers (1, 2) is established;
- and
- driving means cooperating with said mobile piercing member (8) to move said piercing member (8) at least in rotation along said moving axis (21) during the movement of said movable part (19, 45) from the inactivated position to said activated position,
- wherein displacement of said piercing member (8) first bores the second sealing member closing said second container (2) and then second bores the first sealing member of the first container (1), wherein,
- said movable part (45) is cylindrical,
- said second end of the first transfer body (3) is cylindrical,
- said movable part includes, on at least a portion of its external surface, a threaded hole (47);
- and
- said second end of the first transfer body (3) includes, on at least a portion of its internal surface, a threading (48) to allow movement of said movable part (45) relative to said second end of the first transfer body (3) along said moving axis (21),
- said means to drive said mobile piercing member (8) is a plate (49) provided into the second central passage (15) and comprising a central hole (50) for allowing the boring element of the piercing member (8) to pass, said hole (50) being surrounded with teeth (51) intended to cooperate with teeth (52) provided on the body of the piercing member (8) to connect said piercing member (8) and said movable part.
