Abstract
A device in a powder cartridge (11) for a dialysis machine (10), having an externally threaded neck (21) which can be closed by means of a screw cap (26). In this screw cap there is provided a normally closed valve (36) which can be adjusted to open position at insertion of the powder cartridge into the dialysis machine. The end wall (28) of the screw cap and the neck (21) have mutually cooperating means (25, 33) which are adapted, when the cap is screwed on, to be interengaged for preventing unscrewing of the cap, and the end wall (28) has a break connection with the rest of the screw cap to allow unscrewing of the cap only under breaking of the connection (29) between the end wall and the rest of the cap in order to separate the end wall from the cap.
