Abstract

La présente invention concerne un bouton de pulvérisation qui présente une fonction de verrouillage, une fonction de capuchon et une fonction de fermeture de sécurité. Le bouton de pulvérisation en résine (10) se fixe sur une tige d'évacuation pour un récipient de pulvérisation et le fluide présent à l'intérieur du récipient est pulvérisé grâce à une pression vers le bas du bouton de pulvérisation (10). Le bouton de pulvérisation (10) comprend une partie de base inférieure (11) et une partie de verrouillage (15) au milieu d'une partie de pression vers le bas (12) au-dessus de la partie de base (11). Ces éléments constitutifs sont tous formés d'une seule pièce et en même temps par un seul ensemble de moules. La section périphérique de l'extrémité inférieure de la partie de base (11) fonctionne comme un capuchon grâce à l'entrée en prise avec la section périphérique de l'extrémité supérieure du récipient. La partie de pression vers le bas (12) comprend un canal de transfert qui est raccordé à la tige d'évacuation et la sortie du canal de transfert sert de buse de pulvérisation (12n). La partie de pression vers le bas (12) peut être pressée vers le bas grâce au retrait de la partie de verrouillage (15). Des parties en saillie (26) sont disposées sur la surface circonférentielle externe de la partie de verrouillage (15).
