Abstract:
A gas barrier synthetic resin container 10 has an opening portion 12 defined by a flange 12A, a body portion 14 having the opening portion 12, and a bottom portion 16 for closing the end of the body portion 14. The container 10 is a wide mouth container having the minimum inside diameter Dmin of the opening portion 12 larger than the maximum inside diameter Dmax of the body portion. Alternatively, the container 10 may be a wide mouth container having the minimum inside diameter Dmin of the opening portion 12 smaller than the maximum inside diameter Dmax of the body portion, the difference between the diameters being equal to or less than 20 mm. A diamond-like carbon film 18 is formed on an outer wall of the body portion 14 and bottom portion 16 of the container 10. After the container 10 has been filled with contents, a metal cover 20 and the flange 12A are double-seamed onto the container to provide improved gas barrier properties to the entire container.
