摘要：
一种内表面经涂覆的塑料容器及其制造方法,提供一种具有优良的气体屏蔽性的内表面涂覆的塑料容器. An inner surface of the coated plastic container manufacturing method thereof, there is provided an inner surface having excellent gas barrier properties of the coated plastic container. 而且,还提供一种在具有优良的气体屏蔽性的基础上,可以抑制树脂中的微量成分的溶出的内表面经涂覆的塑料容器. Moreover, it provides a basis for having excellent gas barrier properties on the surface can inhibit the dissolution of the resin trace components coated by plastic containers. 在内表面侧具有根据含有碳原子的原始原料且通过等离子体CVD形成的以碳素为主要构成要素的非晶碳素涂层. The inner surface side having carbon as a main constituent an amorphous carbon coating according to the original starting material containing carbon atoms and is formed by plasma CVD. 当将涂层中含有的碳原子数设定为100时,使氮原子数的比率小于等于15,或者氧原子数的比率小于等于20,或者氮原子数与氧原子数的总和的比率小于等于27. When the number of carbon atoms contained in the coating layer is set to 100, the ratio of the nitrogen atoms of 15 or less, or the ratio of the number of oxygen atoms is less than or equal to 20, or the sum of nitrogen atoms and oxygen atoms in a ratio of less than or equal 27. 或者,当将涂层中含有的碳原子数设定为100时,使氮原子数的比率小于等于15,氧原子数的比率小于等于20,氮原子数与氧原子数的总和的比率小于等于27. Alternatively, when the number of carbon atoms contained in the coating layer is set to 100, the ratio of the number of nitrogen atoms is less than or equal to 15, the ratio of oxygen atoms is less than or equal to 20, the number of nitrogen atoms to oxygen atoms is less than equal to the ratio of the sum 27. 非晶碳素涂层的氧渗透性小于等于20×10 Oxygen permeability of the amorphous carbon coating 20 × 10 or less
