Abstract

L'invention concerne un procédé pour fabriquer un emballage contenant un produit (P). Un emballage est fabriqué, comprenant un récipient hermétiquement scellé (2) pourvu d'un couvercle (4). Le couvercle comporte un rebord de couvercle et un capuchon de couvercle (42). Sur un côté intérieur, le capuchon de couvercle comprend un compartiment pour recevoir un ustensile (5). Dans un environnement de salle blanche, l'ustensile est placé dans le compartiment. Le compartiment est hermétiquement scellé avec un joint d'étanchéité d'ustensile (6) dans l'environnement de salle blanche, de telle sorte que l'ustensile est enfermé de façon étanche aux gaz dans le compartiment et disposé dans un environnement d'air de salle blanche. Par conséquent, un procédé simple dans lequel l'ustensile est stocké dans un environnement de salle blanche à l'intérieur d'un compartiment hermétiquement scellé est fourni, de façon à réduire efficacement, de façon avantageuse, le risque de contamination. L'ustensile est maintenu propre jusqu'à ce qu'un utilisateur retire ou casse le joint d'étanchéité (6) du compartiment.
