One aspect relates to a device for producing a bone cement paste from a monomer liquid and a cement powder and for delivering the bone cement paste, the device having a cartridge with a cylindrical interior, the interior of the cartridge being closed at the front side apart from a delivery opening for discharging the bone cement paste from the interior. A delivery plunger is arranged in the interior of the cartridge and mounted so as to be pushable in the direction of the delivery opening. The cement powder is arranged in the interior of the cartridge between the delivery opening and the delivery plunger. A closure closes the delivery opening and is mounted so as to be movable relative to the delivery opening. A line element is arranged at the front side of the delivery opening and includes a closure receptacle for receiving at least part of the closure. The closure is pushable into the closure receptacle by pressure on the bone cement paste such that the delivery opening is opened, when the closure has been pushed into the closure receptacle, the line element provides a free line cross-section through which the bone cement paste is pushable out through the delivery opening and out…
