<p><P>PROBLEM TO BE SOLVED: To provide a container which can be prevented from being carelessly dropped when the the container to be used in an upside-down state by gripping the bottom part is used. <P>SOLUTION: A step difference 18 in which a bottom part 17 larger than a drum section 16 is integrally formed between the drum section 16 and the bottom part 17 of a container body 11. The width W of the step difference 18 may be formed in such a manner that the bottom part 17 may be larger than the drum section 16 within a range of 0.5-30 mm. The bottom part 17 may be formed so that the formula: 2×A+B<100 mm can be satisfied when a height from the bottom surface 17a to the step difference 18 is expressed as A, and the width of the bottom section 17 in the short circle direction is expressed as B. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
