Title (EN) NITROGEN-FREE DLC FILM COATED PLASTIC CONTAINER, AND METHOD AND APPARATUS FOR MANUFACTURING THE SAME
(FR) RECIPIENT EN PLASTIQUE REVETU D'UNE COUCHE DE CDA EXEMPTE D'AZOTE, PROCEDE ET APPAREIL UTILISES POUR SA FABRICATION
Abstract:
(EN) A plastic container having an inner surface coated with a DLC (diamond like carbon) film, wherein the DLC film has a nitrogen content less than 0.2 atomic % and exhibits physical properties required of a film coated on the inner surface, and the container is safe and hygienic. The plastic container is manufactured by a method comprising using a raw material gas for coating having a nitrogen content less than 500 ppm, or preferably a method further comprising a step of reducing a pressure in the container to a specific vacuum pressure or less and a step of introducing the raw material gas to the container while evacuating the container, to thereby replace an original gas having the specific vacuum pressure with the raw material gas.
(FR) L'invention concerne un récipient en plastique sûr et hygiénique, possédant une surface intérieure revêtue d'une couche de CDA (carbone sous forme de diamant) présentant un pourcentage atomique d'azote inférieur à 2 et les propriétés physiques requises d'une couche appliquée sur la surface intérieure. Ledit récipient en plastique est fabriqué selon un procédé consistant à utiliser une matière première gazeuse pour le revêtement, présentant une teneur en azote inférieure à 500 ppm, ou de préférence selon un procédé consistant en une étape de réduction de la pression dans le récipient jusqu'à l'obtention d'une pression négative spécifique ou inférieure, et en une étape d'introduction de la matière première gazeuse dans le récipient pendant que ce dernier est vidé, ce qui permet le remplacement du gaz d'origine à la pression négative spécifique par la matière première gazeuse.
