<p>The invention concerns various base plates arranged in a ring on the dispenser platform, each base plate having a cylindrical wall comprising curved surface elements and substantially planar surface elements. The invention is characterised in that it consists in arranging modular wall elements with curved surface (201, 202, 211, 212) and wall elements with planar surface (22, 23, 24) according to a predetermined base plate geometry, and in assembling said elements along their adjacent edges, to produce the base plate cylindrical wall.</p> |
