PROBLEM TO BE SOLVED: To cover a container body beautifully with a film in a good yield even when circumferential length differences among parts of the container body are increased to achieve both good gripping properties for a user and capacity enlargement.SOLUTION: A container body 20 comprises: a mouth part 21; a neck part 22; a shoulder part 23; and a trunk part 24. The minimum circumferential length of the neck part 22 is a half of the maximum circumferential length of the trunk part or smaller. A film 30 is formed so as to cover the area from the neck part 22 to the trunk part 24 of the container body 20. At least the outer surface of the neck part 22 of the container body 20 is subjected to a slippage improvement treatment for improving the slippage of the film 22. |
