PLASTIC PACKAGE COATED WITH DIAMOND-LIKE CARBON FILM, DEVICE FOR FABRICATING THIS PACKAGE AND METHOD FOR PACKAGE FABRICATING Russian patent published in 2008 - IPC C23C16/26 B65D23/02 

FIELD: metallurgy.

SUBSTANCE: invention refers to plastic package with inside surface of wall coated with diamond-like film; invention also refers to device for fabricating this package and to method of package fabricating. The device contains an electrode encompassing the package and forming one portion of a chamber for pressure fall where the package and a facing electrode located inside the package above an aperture are arranged. The said electrodes face each other and are divided with an insulating body forming portion of the pressure fall chamber. A device for source gas supply contains an inlet pipe of supplied gas. There are also a pumping out device and a device of high frequency supply. The method includes pumping out the package contents till achieving the pressure less or equal to specified, then introduction of source gas for generating plasma, termination of pumping out and decreasing the rate of introduction of the source gas to the value less than the rate of introduction at the moment of change, generating plasma for formation of diamond-like carbon film on the interior surface of the plastic package wall. Thus the package with film is produced; the said film has equal level of oxygen impenetrability; and colouring of film formed at the throat portion of the package is avoided.

EFFECT: production of package with diamond-like carbon film with uniform level of oxygen impenetrability.
