Abstract: A synthetic resin-made container is a synthetic resin-made container that has an outer layer body and an inner layer body separably laminated on an inner surface of the outer layer body and is formed by stretch blow molding, and includes: a tubular mouth portion; a barrel portion connected to and located below the mouth portion; and a bottom portion closing a lower end of the barrel portion, wherein the outer layer body contains polyethylene terephthalate, the inner layer body contains polyethylene terephthalate, a laminate containing polyethylene terephthalate, or a blend containing polyethylene terephthalate, and has a vapor-deposited film having a gas barrier property on an inner surface thereof, and a rib that prevents the inner layer body from peeling away from the outer layer body when forming the vapor-deposited film is formed in at least one of a lower part of the barrel portion and the bottom portion.

Abstract: A synthetic resin container possessing a higher gas barrier property, and having a coating film (2) possessing a higher gas barrier property and positioned on an inner surface and/or and outer surface of the container body, wherein at least the coating film (2) is constituted of: an organic silicon compound layer (2a) positioned on the or each surface of the container body and including nitrogen, silicon, carbon, hydrogen, and oxygen; and a silicon oxide compound layer (2b) including a silicon oxide compound as a main component.

Abstract: A synthetic resin container possessing a higher gas barrier property, and having a coating film possessing a higher gas barrier property and positioned on an inner surface and/or outer surface of a body of the container, wherein the coating film (2) is constituted of a layered coating including at least a gas barrier coating (2a) and a cover coating (2b), the cover coating being positioned at a topmost side of the coating film. The cover coating (2b) includes a layer positioned at a topmost side of the cover coating and possessing such a water repellency that the layer has a contact angle with water of 80° to 100°. The layers (2a, 2b) constituting the coatings, respectively, are each formed by vapor deposition and each have a refractive index in a range of 1.3 to 1.6.
