A hollow, blow-molded container of a biaxially oriented saturated polyester resin in which the upper part of the neck section is formed thicker than the intermediate section, and the upper half part of the upper part is formed thicker than the lower half part of the upper part. Thus, a cap can be exactly mounted on the neck section of this container, and the quantity of the material of the neck section can be reduced.

Container of polyethylene terephthalate or saturated polyester resin

A bottle made of a saturated polyester resin and having one or more strip-shaped projection for the reinforcement and ornament purposes is provided, which bottle is produced by a method comprising the steps of preparing a parison having an opened upper end and a closed bottom end from a saturated polyester resin, welding a strip-shaped piece made of the same saturated polyester resin on said parison so as to extend in the vertical direction, and then biaxially orientating said parison and said strip-shaped piece as an integral body.

Method of making a bottle of saturated polyester resin

The present invention relates to a saturated polyester resin bottle with a spherically-shaped bottom so that the bottle can be filled with liquid under a relatively high pressure. The bottle includes adjacent its bottom a reduced diameter portion shaped for receiving a cylindrical bottle stand which provides a flat base for supporting the bottle in an upright position.
