Abstract
Boquilla perfeccionada, esencialmente caracterizada porque cada una de sus dos partes articuladas está constituida por una sola plancha a la que, por troquelado, se le han configurado los dos brazos y en los extremos de estos las lengüetas perforadas que, tras retorcerlas, se unirán las de una parte y otra para articular a las dos planchas unitarias referidas, las cuales tienen doblada con perfil acanalado, de media caña, en U u otro, la ancha banda o franja de la que parten los brazos que tienen practicados o no en su centro y longitudinalmente una o varias ranuras configurando un o varios nervios que dan rigidez al respectivo brazo.
