摘要：<p>A plastic container is coated with DLC film as a desirable oxygen barrier so that it is suitable for containing oxygen-sensitive or carbonated beverage. A coating device comprises an outer electrode arranged outside a plastic container (5), an inner electrode (11) arranged inside the plastic container (5), a pipe (12) through which carbon source gas is supplied to the plastic container (5) pumped to a low pressure, and a high-frequency oscillator (9) for applying voltage between the outer electrode and the inner electrode (11) after supplying the source gas to generate a plasma for depositing DLC film on the inner wall of the plastic container (5). The outer electrode includes a bottom electrode (4) arranged along the bottom of the plastic container (5) and a wall electrode (3) arranged along the inner wall of the plastic container. The bottom electrode (4) is located below half the complete height of the plastic container (5).</p>
