<p><P>PROBLEM TO BE SOLVED: To suppress deformation of the central wall part on a bottom part. <P>SOLUTION: A bottle 10 having such a constitution as follows is provided. Cylindrical opening part, shoulder part and barrel part, and a bottomed cylindrical bottom part 14 are integrally formed of a synthetic resin material. The bottom part includes a central wall part 15 which is arranged in the central part and the bottle axis intersects at right angles, and a connecting peripheral wall part 16 for connecting the outer peripheral edge of the central wall part and the barrel part. On the connecting peripheral wall part, a plurality of longitudinal recessed stripe parts 17 are circumferentially formed at intervals in the bottle along around the bottle axis O. A leg part 18 positioned between adjacent longitudinal recessed stripe parts in the bottle peripheral direction on the connecting peripheral wall part is equipped with grounding projecting part 19 projecting toward the outside of the bottle axial direction from the central wall part. On the inner face of the bottom part, a reinforcing wall part 21 for connecting the central wall part and the connecting peripheral wall part is projected. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
