Claim 45:
46. A nebulizer (1) for a fluid (2), comprising:
a cartridge (3) with a container (4) containing the fluid (2),
a housing (20) for receiving the cartridge (3),
a delivery mechanism (10) for pressurizing the fluid (2) after the fluid is withdrawn from the cartridge, and
a connecting element (14) for fluidically connecting the cartridge (3) to the delivery mechanism (10), wherein:
the cartridge (3) comprises a tube (25) disposed within the container (4) for conveying the fluid (2) out of the container (4), and being at least partially flexible and/or bendable,
a closure (7) with a connection port (9) cooperating with an opening of the container (4) for fluidically and/or sealingly connecting the container (4) to the nebulizer (1),
an adapter (26) mechanically and/or fluidically connecting the tube (25) to the connection port (9) of the closure (7) by sealingly receiving the connection port (9) therein, such that the container (4) is in fluidic communication with the connecting element (14) of the nebulizer (1),
the cartridge (3) comprises a rigid intermediate piece (29) to fluidically connect the tube A (25) to the connecting element (14), and wherein
the intermediate piece (29) is axially moveably, and axially pushable, into or onto or together with the tube (25) by the connecting element (14) in order to compensate length tolerances of the connecting element (14).
