<p>A stacking plate (4) comprising a base (8) with an inner wall (12), an outer wall (16), opposite the inner wall (12) and a perimetral rim (20) which surrounds and defines the base (8). The plate is characterised by the fact that the perimetral rim (20) has at least one raised portion (24) and at least one lowered portion (28), joined to each other, so that the perimetral rim (20) is not entirely a solid of revolution in relation to an axis perpendicular to the base (8), and by the fact that the base (8) comprises, on the side of the inner wall (12), a perimetral groove (32) able to form a shaped coupling with the perimetral rim (20) of a further stacking plate (4) which may be joined to it.</p> |
