<p>PROBLEM TO BE SOLVED: To provide a DLC film coating cap and a resin container with a cap capable of suppressing an influence of oxygen amount which permeates the cap as a whole by preventing oxygen permeability from the cap from getting near to oxygen permeability from a bottle even when the cap is formed with LDPE.SOLUTION: A DLC film 60 having a thickness of 0.1 to 20μm is formed on the surface of a cap 1 made of low-density polyethylene to be attached to a mouth part of a resin container. The cap 1 is a hinge cap including: a cap main body 2 which is fitted and fastened to the mouth part; a cover body 3 freely attachable to the cap main body 2; and a hinge 4 which connects the cover body 3 to the cap main body 2 openably and closably and the DLC film 60 is formed only on the outer surfaces 51, 52 in a closed state.</p> |
