Abstract
The present invention provides a plastic container or bottle having an inner wall surface coated with a DLC film which has the same level of oxygen barrier property as prior art DLC coated containers while at the same time preventing the coloration of the neck portion found in the containers of the prior art. The DLC film formed on the neck portion of the inventive bottle has a lower graphite mixing proportion than the DLC film formed on body portion, and the oxygen permeability of the container is less than or equal to 0.0050 ml/container (500 ml PET container)/day. The apparatus and the method of producing such a bottle are also described.
