<p><P>PROBLEM TO BE SOLVED: To provide a pressure-resistant bottle capable of reducing the deformation of a bottom when the pressure inside the bottle is positive, and preventing consumers from misunderstanding a content since the appearance shape is close to that of a general bottle. <P>SOLUTION: The pressure-resistant bottle 10 includes a mouth 11, a barrel 12 and a bottom 20. The bottom 20 has a plurality of legs 21 extending from the center 20a to the peripheral edge 20b, and projecting downward, and a flat face 22 extending downward from the center 20a to the peripheral edge 20b is formed in each part between the legs 21. The ground contact surface 21a of each leg 21 is formed in a curved shape in a section from the center 20a to the peripheral edge 20b. Thus, the deformation of the bottom 20 can be suppressed when the pressure inside the pressure-resistant bottle 10 is positive. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
