ABSTRACT OF THE DISCLOSURE. To permit easy removal of a printing machine inker fountain box, without leakage of ink from the box, the box is formed with a box body (1) and side walls (3) which have curved front faces (12) fitting against an inker roller (9). To remove the box, for example by lifting off with handles (2) from a printing machine, a curved cover (4) is inserted into guide slots (5) formed in the side walls, which are located just inside of the end surfaces (12) of the end walls. The cover, preferably, has a stripper element (6) at the end, so that, as it is inserted into the curved slots (5), ink on the inker roller (9) is stripped downwardly leaving, at the end, only a small accumulation of ink (19) which can easily be wiped off. The bottom of the inker cover (4) fits against the inker body (1) to prevent leakage of ink from the now removable inker box (1). To permit return of ink stripped off the inker roller (9) in operation of the machine by a doctor blade (22) mounted on the inker body (20), the bottom wall (1") of the inker body is formed with a recessed edge (127) or a group of apertures (27) therein, which can be closed off by a flap (28) of a flap valve, or by a sealing strip or flap (28, 928) secured to the cover (4) and overlapping the opening (127) or openings (28) when the cover is inserted in the guide slots.
