Abstract

Dans un procédé destiné à fabriquer une cartouche (1), on fabrique dans une première étape une chambre de réserve (5, 6, 7) pour le logement d'une masse de remplissage (8, 9, 15), un col (2) avec un canal de sortie (11, 12) pour la masse de remplissage (8, 9, 15) et un bouchon de fermeture (20) dans le procédé de moulage par injection. Sur une extrémité (16, 17) du canal de sortie (11, 12) est disposée une ouverture de sortie (10, 14). L'ouverture de sortie (10, 14) est fermée au moins partiellement par un bras (21, 22) du bouchon de fermeture (20). Une première extrémité (23, 24) du bras (21, 22) est reliée au col (2) par un élément de pont (18, 19). Par l'élément de pont (18, 19) est réalisé un point de rupture théorique sur lequel le bouchon de fermeture (20) est relié d'une seule pièce à la cartouche (1). Le bouchon de fermeture (20) a une seconde extrémité (26), qui peut être manipulée dans une seconde étape consécutive de telle sorte que l'élément de pont (18, 19) déconnecte avant le remplissage de la cartouche (1) avec la masse de remplissage (8, 9, 15), et qu'ensuite le bras (21, 22) est introduit dans l'ouverture de sortie (10, 14) afin de fermer l'ouverture de sortie (10, 14).
