<p><P>PROBLEM TO BE SOLVED: To provide a synthetic resin bottle for realizing a reduced pressure absorbing function not only in view of a shape of bottle but also in view of a synthetic resin material to be used and further having a requisite and sufficient reduced pressure absorbing function. <P>SOLUTION: A bottle formed by a direct blow molding method is constituted such that at least two vertical band layers in a vertical direction made of hard synthetic resin as compared with major synthetic resin forming a main body of the bottle are stacked at substantial axial symmetrical positions over a full height of the bottle main body, the formed portions of aforesaid vertical bands are applied as columns and then an area having the reduced pressure absorbing function is arranged between the columns. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
