Abstract
A bottle has a high strength against pressure-reduction without reducing the internal content. The bottle is made up of a circular bottom; a barrel portion extending upwardly from the outer peripheral edge of the bottom portion; and a plurality of recessed portions each having a longitudinal and approximately rectangular shape, which are spaced from each other along the circumferential direction of the barrel portion. Each of the recessed portions includes a recessed panel surface fallen in from the barrel portion by a specified stepped dimension and two pieces of swelling bodies that swell in the outer peripheral direction from the recessed panel surface by a specified height. Two of the swelling bodies, each being formed into a trapezoidal shape having a flat upper end surface, are longitudinally spaced from each other along the longitudinal length of the bottle.
