The body ( 24 ) has a first end ( 52 ) and a second end ( 53 ), and is provided with a least one slit-shaped opening ( 55 ) extending through the wall. The first end is open and adapted for receiving liquid to be introduced into the cartridge. The liquid leaves the device through the slit-shaped opening in a flow direction. The slit-shaped opening has a first extension and a second extension substantially perpendicular to the flow direction and to the first extension. The second extension is significantly shorter than the first extension.
