Abstract

L'invention concerne un dispositif indicateur indiquant l'enlèvement d'un couvercle protecteur (82) de l'orifice d'un contenant de boisson (2), et un procédé de production de ce dispositif indicateur. Le dispositif indicateur comprend un connecteur mâle (90) et un connecteur femelle (91) conçus pour se verrouiller, le couvercle (82) comportant une partie de connexion indicatrice (90, 91), alors que le contenant de boisson (2), ou un capuchon (6) qui lui est connecté, comporte l'autre partie de connexion (91, 90). Les parties (90, 91) se verrouillent avant le premier enlèvement du couvercle (82). Après le premier enlèvement du couvercle (82), cet assemblage est difficile à refaire pour un utilisateur, car les parties de connexion séparées (90, 91) indiquent un enlèvement précédent du couvercle protecteur (82).
