<p>To provide an additives container (1) housable in the restricted space available in a water-closet flushing cistern (2) while at the same time being easy to replace, the casing (3) of said container (1) is substantially of C-shape in plan view such as to define in its rear part a cavity (5) lying between two portions (6, 7) symmetrical about the plane of symmetry (8) which contains the delivery axis (9). Said symmetrical portions (6, 7) are of rectangular trapezoidal section in correspondence with the plane of symmetry (8). The container casing (3) also comprises in its lower part (10) an annular groove (11) which enables it to be locked by insertion into a guide (12) on the flushing cistern (2), and on its front part (13) a projecting gripping portion (14). The delivery valve (4) is of normally closed type, openable by being pressed in the direction of the interior of the container casing (3), and is snap-fitted to said container casing (3). <IMAGE></p> |
