Abstract

L'invention concerne une aiguille empêchant un perçage erroné: le perçage dans un corps est difficile, mais le perçage dans des objets autres que le corps est facile, comme dans le couvercle d'un contenant de produits chimiques. Cette aiguille comprend un biseau (12) formant l'ouverture de l'extrémité d'un trou d'aiguille (11) et une surface plate (13) généralement orthogonale par rapport à une surface périphérique externe à l'extrémité.
