Abstract

L'invention concerne un bouchon de bouteille anti-mauvaise opération, comprenant un bouchon externe (100), un bouchon interne (200) et un bouchon de récipient de matériau (300). Le bouchon externe est disposé au-dessus du bouchon interne, le bouchon externe peut tourner par rapport au bouchon interne, un récipient de matériau est disposé dans le bouchon interne et le bouchon externe est relié au bouchon de récipient de matériau ; le bouchon externe commande, au moyen de la rotation, le bouchon de récipient de matériau pour ouvrir le récipient de matériau ; et le bouchon externe correspond au bouchon interne au moyen d'une clavette et d'une rainure de clavette, de manière à distinguer une opération d'ouverture du récipient de matériau au moyen du bouchon externe d'une opération d'ouverture du bouchon de bouteille au moyen du bouchon externe. Selon le bouchon de bouteille, la clavette et la rainure de clavette sont disposées entre le bouchon externe et le bouchon interne pour une mise en correspondance et l'opération d'ouverture du récipient de matériau est distinguée de l'opération d'ouverture du bouchon de bouteille au moyen d'une direction de rotation du bouchon externe, de telle sorte qu'une mauvaise opération d'un utilisateur est évitée.
