<p><P>PROBLEM TO BE SOLVED: To restrict a deformation of synthetic resin bottle under its pressurization that has such a shape as one having its diameter reduced toward a substantial central height position of its barrel part and provide such a synthetic resin bottle having such a shape as one not found in an application where its inner part is pressurized. <P>SOLUTION: A round-type bottle used for an application where its inner part turns pressurized and having a pressure-resistant bottom part has a constitution in which its barrel part has a diameter reduced segment within a predetermined height range extending from its upper end and lower end toward the central height position, a wall thickness of a barrel wall at the diameter reduced segment is made thick and a bulged-out deformation of the barrel part under the pressurization can be restricted. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
