The following are not eligible for protection:
1° An appearance whose characteristics are exclusively imposed by the technical function of the product;
2° The appearance of a product whose exact shape and size must necessarily be reproduced so that it can be mechanically associated with another product by being brought into contact, connected, placed inside or outside under conditions that allow each of these products to fulfil its function.
However, a design whose purpose is to allow multiple assemblies or connections to products that are interchangeable within a modularly designed assembly may be protected.
