PROCESS FOR THE INTERNAL COATING OF HOLLOW BODIES

A method is disclosed in which a vapor-deposited coating or layer is directly or indirectly applied to at least a portion of the internal wall of the barrel of a capped pre-assembly comprising a barrel, a dispensing portion, and a shield. The shield is secured to the barrel and at least substantiall...

Beschreibung
Zusammenfassung:	A method is disclosed in which a vapor-deposited coating or layer is directly or indirectly applied to at least a portion of the internal wall of the barrel of a capped pre-assembly comprising a barrel, a dispensing portion, and a shield. The shield is secured to the barrel and at least substantially isolates the distal opening of the dispensing portion from pressure conditions outside the shield. A vapor-deposited coating or layer is applied directly or indirectly to at least a portion of the internal wall of the barrel while the pre-assembly is capped. The coating or layer is applied under conditions effective to maintain communication between the barrel lumen and the dispensing portion lumen via the proximal opening at the end of the applying step. The capped pre-assembly can be pressure tested easily and rapidly, for example with a test duration between 1 and 60 seconds, to determine whether it has container closure integrity. La présente invention concerne un procédé dans lequel un revêtement ou une couche déposé(e) en phase vapeur est appliqué(e) directement ou indirectement sur au moins une partie de la paroi interne du cylindre d'un pré-ensemble à capuchon comprenant un cylindre, une partie de distribution et un élément de protection. L'élément de protection est fixé au cylindre et isole au moins sensiblement l'ouverture distale de la partie de distribution des conditions de pression extérieures à l'élément de protection. Un revêtement ou une couche déposé(e) en phase vapeur est appliqué(e) directement ou indirectement sur au moins une partie de la paroi interne du cylindre alors que le pré-ensemble est recouvert avec un capuchon. Le revêtement ou la couche est appliqué(e) dans des conditions efficaces pour maintenir la communication entre la lumière du cylindre et la lumière de la partie de distribution via l'ouverture proximale à la fin de l'étape d'application. Le pré-ensemble à capuchon peut faire l'objet d'un essai de résistance à la pression facilement et rapidement, par exemple avec une durée de test comprise entre 1 et 60 secondes, pour déterminer s'il possède une intégrité de fermeture de récipient.
