<p>PROBLEM TO BE SOLVED: To provide a synthetic resin container which can prevent deformation due to pressure reduction after high-temperature filling of contents and also which is reduced in weight. SOLUTION: The synthetic resin container comprises a mouth 3, a neck 4 connected to the mouth 3 increasing in diameter downwardly from the mouth 3, a body 5 connected to the neck 4 and a bottom 6 connected to the body 5 for constituting a ground part 6b. At the time of filling contents at high temperature, liquid nitrogen for setting the inside of the container at a positive pressure is sealed together with the contents. A plurality of circumferential ribs 7 are provided on the body 5 while discontinuous parts 8 are provided on the ribs 7. The discontinuous parts 8 are provided at the same positions in the respective ribs 7 and form a longitudinal array vertically on the body 5. The discontinuous parts 8 are formed at positions different from each other on adjacent ribs 7, 7.</p> |
