Abstract: The invention relates to a board for blind persons, which makes it easier to write, draw and learn shapes through positive relief elements that can be reused. When writing or drawing, it is possible to check what has been done and to correct errors detected with the fingertip (4). Said board has a grid (3) for picking up, putting down and storing small-size relief elements (1). Said relief elements are placed on a panel (2) with a matrix of holes, forming letters and drawings. There is a means for making copies of what was written or drawn. Drawing tools or stencils that can be attached with pins to the matrix of the panel are provided. Once the activity is finished, there is a means of collecting the relief elements and storing same in the container in the panel or the grid.

Abstract: The ultraviolet and/or ozone-generation disinfection cutlery tray allows to improve the hygiene of the different cutlery items placed in it, by use of at least one ultraviolet light and/or ozone-generating source that irradiates the cutlery through the material itself making up the cutlery tray, made of a light-conductive plastic material, obtaining an homogeneous radiation, allowing objects that had been previously washed in a conventional way to maintain and conserve asepsis until the moment of use. Versions are contemplated for holding cutlery in vertical position, simultaneously allowing their drainage after washing and hygienization; and others in which the emission of ultraviolet light is located on the surface of the material making up the cutlery tray. The disinfection device is suitable for use for the domestic sector, catering industry, as well as the clinical sector.
