<p><P>PROBLEM TO BE SOLVED: To provide a plastic container in which its bottom part can easily be deformed and at the same time a dispersion of an entire height of the container can be restricted. <P>SOLUTION: The plastic container 10 has an opening part 11, a barrel part 12 and a bottom part 13. The bottom part 13 has a curved part 13a and a ground-contact part 13b connected to the outer peripheral edge of the curved part 13a through a fulcrum point 13c. In the case that the bottom part 13 is pushed up, the curved part 13a is dented inward around the fulcrum point 13c. Since the fulcrum point 13c is positioned above the ground-contact part 13b, a position of the ground-contact part 13b is kept constant to enable a dispersion of an entire height of the container to be restricted. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
