The tube shoulder (1) as such also forms a baseplate (1) for the hinged tube seal and in addition produces a nest (4) acting as fixed receiver for a separate cap, or alternatively to take a movable cap. The cap performs two movements, notably the cap is tipped or tipped and shifted. The nest and boundary bolt consists of a single shoulder (19) hole to the side sealed off from the tube interior. Apart from the boundary bolt, the nest can also be located by flexible lips (3).
