One aspect relates to a device for producing a bone cement paste from a monomer liquid and a cement powder as parent components of the bone cement paste and for delivering the mixed bone cement paste, the device having a cartridge having a cylindrical interior. The interior of the cartridge is closed on the front side except for a delivery opening for expelling the bone cement paste. A delivery plunger is arranged in the interior of the cartridge. The cement powder is arranged in the interior of the cartridge. A closure is arranged on the front side of the delivery plunger. The closure closes the delivery opening when the delivery plunger is pressed against the front side of the interior of the cartridge. The closure blocks a further movement of the delivery plunger so that the delivery plunger is spaced from the front side of the interior of the cartridge at least in some areas and a dead volume remains in the interior of the cartridge when the delivery plunger is pressed against the front side of the interior of the cartridge.
