<p><P>PROBLEM TO BE SOLVED: To provide a new container made of a synthetic resin which is capable of efficiently spouting the content remaining in the container. <P>SOLUTION: In an extrusion blow molded bottle 1 made of the synthetic resin on which a parting line P<SB>L</SB>is formed so as to divide a bottom part 5 into two, the parting line P<SB>L</SB>is made eccentric to the bisector L<SB>O</SB>of the bottom part 5. Thereby, in the inner face of the bottom part wall, the biased side of the parting line P<SB>L</SB>becomes inevitably thick, and as the inner face of the bottom part wall goes away from the biased side of the parting line P<SB>L</SB>, it is biased thinner. Therefore, the inner face 5f of the bottom part wall becomes inevitably to a gradually inclined face as it goes away from the biased side of the parting line P<SB>L</SB>. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
