Abstract

Pendant le transport de capsules de bouteilles (BC) dans lesquelles des rabats (18) formés sur la surface circonférentielle interne d'une section (11) de bande circulaire inclinée vers l'extérieur à partir du centre axial (O) de la capsule, les capsules de bouteilles (BC) sont stérilisées en exposant leurs surfaces externes à un faisceau d'électrons. Ensuite, le procédé de stérilisation et de mise en place de capsule de bouteille effectue : une étape de stérilisation de surface interne pour stériliser les surfaces internes en rapprochant ou en insérant une pièce buse (46N), qui a une ouverture d'exposition (46P) sur la pointe, dans la surface ouverte (14) de la section (11) de bande circulaire et en l'exposant à un faisceau d'électrons ; une étape de pliage de rabats pour plier les rabats (18) vers l'intérieur vers le centre axial (O) de capsule et vers la surface supérieure (12) ; et une étape de mise en place de capsule pour mettre en place les capsules de bouteilles (BC) sur les goulots des contenants.
