Device for two-way transfer of a liquid between a bottle and a cartridge
First Claim
1. A device for two-way transfer of a liquid (38) between a bottle (14), provided with a perforable stopper (44), and a cartridge (12), comprising a cylindrical reservoir (26) in which a perforable piston (34) slides, characterized in that it includes:
- a body (16) having means for fixing to the bottle (14), a member (24) for connecting the perforable piston (34) to the body (16), a shuttle (20) which is displaceable relative to the body (16) and to said connecting member (24), the shuttle (20) bearing a hollow needle (22) of which a first end (112) is adapted to perforate the piston (34) and of which the second end (114) is adapted to perforate the stopper (44), and in that the shuttle (20) is displaceable between an initial position, in which the needle ends (112, 14) are spaced apart from the perforable piston (34) and the perforable stopper (44), and a final transfer position, in which the needle ends (112, 114) are received in the cartridge (12) and the bottle (14).

Abstract
The invention concerns a device for the two-way transfer of a liquid (38) between a bottle (14) provided with a cap (44) capable of being perforated at a cartridge (12) comprising a cylindrical reservoir (26) wherein slides a piston (34) capable of being perforated. It comprises: a body (16) including means to be fixed on the bottle (14); a member (24) linking the piston (34) capable of being perforated to the body (16); a shuttle (20) relative to the body (16) and said linking member (24), the shuttle bearing a hollow needle (22) whereof one first end (112) is adapted to pierce the piston (34) and whereof the second end (114) is adapted to pierce the cap (44). The shuttle (20) is mobile between a piston wherein the needle ends (112, 114) are spaced apart from the piston (34) capable of being perforated and the cap (44) capable of being perforated and an end-of-stroke transferring position wherein the needle ends (112, 114) are received in the cartridge (12) and the bottle (14).
