PURPOSE:To improve the gas barriering property by forming a paint film having the gas barriering property on the outer surfce of a hollow body consisting of polyethylene terephthalate, and drying while rotating the body around the central axis and shaking. CONSTITUTION:The drum part 1c and the bottom part 1d of a bottomed parison 1 consisting of polyethylene terephthalate is immersed in a liquid paint, and a paint film 2 is formed on the outer surface. Then while rotating the parison 1 around the central axis, the shaking of the central axis in both elevating and depression angle directions or only in the depression angle direction by using the mouth neck part 1a side as a fulcrum is alternated with the rotation around a horizontal axis 5. The paint moved from the bottom part 1d to the drum part 1c by the rotation around the horizontal axis is returned to the bottom part 1d, and the thinning of the thickness of the coated film on the bottom part can be prevented. |
