A breast pump (1), having - a milk container (2) with a cavity (3) for receiving expressed milk; - a breast shield (4) which has a breast funnel (5) and a nipple tunnel (6); - a connection element (7) which connects an opening (8) into the cavity (3) of the milk container (2) to the nipple tunnel (6); - an air release channel (9), the first end (10) of which is open to the cavity (3) of the milk container (2) and the second end (11) of which is open to the surroundings, wherein at least one portion of the air release channel (9) extends along the connection element (7), wherein the air release channel (9) extends at least in part along a portion at which the connection element (7) receives the nipple tunnel (6).

The invention relates to a closing screw (10) for a projectile (100), comprising a screw body (14) extending along a central longitudinal axis (M), wherein a channel (16) is formed in the screw body (14), which extends relative to the central longitudinal axis (M) from a first side (18) of the screw body (14) to a second side (20) of the screw body (14), wherein a closing element (22) is arranged in the channel (16), which closes the channel (16) and is configured in such a way that, when a defined limit pressure in the channel (16) is exceeded, the closing element (22) at least partially fails and at least partially releases the channel (16).

A head-maintenance device includes a suction cap to cap a nozzle surface of a head to discharge liquid, a suction unit to suck the inside of the suction cap, an air-release channel communicating with the inside of the suction cap, a lid to close an opening of the suction cap, and processing circuitry. The processing circuitry performs an air-release channel suction operation to close the air-release channel and suck the inside of the suction cap by the suction unit, with the opening of the suction cap closed by the lid, and open the air-release channel with the inside of the suction cap in a negative pressure.
