In a conveyance line for work that is produced by forming semi-finished containers on a container-forming plastic sheet that is continuous in a belt shape, DLC films can be formed in the line on the surfaces of the intermittently arriving semi-finished containers without use of a special loading/unloading mechanism. An upper casing (11A) placed above a conveyance line for work (W) and a lower casing (11B) below the conveyance line are joined to form a vacuum chamber (11) that receives intermittently arriving semi-finished containers (3...) by a predetermined number of containers for each arrival and applies DLC coating on the surfaces of the containers. A seal material (32) is attached to the portion of the joining, and the seal material is capable of maintaining the inside of the chamber (11) at vacuum of 0.5-5000 Pa. Also, when the semi-finished containers (3...) are loaded into and unloaded from the vacuum chamber (11), the casings (11A, 11B) are relatively moved in the direction where the casings are separated from each other, enabling the loading and unloading of the containers.
