Estimating the term…
The dosing apparatus comprises a conveying device (5), which is driven by at least one conveying drive (4), for conveying fluid from the interior (3) of a container (2). The fluid by means of the conveying device (5) is conveyable from the container to a dispensing opening (6). The conveying device (5) comprises a cylinder (7) having at least one intake opening (11) and at least one outlet opening (12) on an inner cylinder wall (8), and a first piston (9) and a second piston (10). The first piston (9) and the second piston (10) are mounted within the cylinder (7) so as to be displaceable in the longitudinal direction. Furthermore, the first piston (9) and the second piston (10) between the end sides thereof and together with a portion of the inner cylinder wall (8) delimit a variable fluid volume (17).
1-20. (canceled)
A dosing device for dispensing a fluid under aseptic conditions, comprising at least one container with an interior, and a conveying device which is driven by at least one conveying drive in order to convey the fluid out of the interior of the at least one container, wherein the fluid is conveyable by means of the conveying device from the container to a dispensing opening, wherein the conveying device comprises a cylinder, with at least one intake opening and at least one outlet opening on a cylinder inner wall, and also a first piston and a second piston, wherein the first piston and the second piston are mounted inside the cylinder in such a way as to be displace able in the longitudinal direction, and wherein the first piston and the second piston, between the end faces thereof and together with a portion of the cylinder inner wall, delimit a variable fluid volume, characterized in that the dosing device comprises a drive module and a dispensing module which are configured so as to be mutually connectable and separable by a user, wherein the drive module comprises at least parts of the conveying drive, in particular optionally a rotary drive, and/or optionally an application drive of an injection device, and the dispensing module has at least the container and also the conveying device and optionally the injection device, and the container is at least partially collapsible.
