Abstract
A liquid-depositing implement includes a tubular case (1) containing a supply chamber (2) and a reservoir (3) isolated from the chamber with both the chamber and reservoir being fillable with a deposition liquid. A depositing element (6) can be mounted to the case (1) and connected to the supply chamber (2). The supply chamber includes a valve-system (4) composed of two mutually telescoping and displaceable bushes (9, 10) resting tightly against each other and enclosing a cell (16) bounded at each of its axial ends by at least one base (14, 15) affixed to the inner or outer bush. Two sets of cooperating valve apertures (17, 18; 19, 20) are present in such manner in the walls of the bushes (9, 10) that by rotating one bush (10) relative to the other bush (9), first one set of valve apertures (19, 20) passes from a communicating position to a sealed position and thereupon the other set of valve apertures (17, 18) passes from the sealed position into the communicating position.
