PURPOSE: To facilitate the placing detaching operation of a lid by a method wherein when the lid part is fitted on a container main body, a protruding part is held in an engaging groove, and is made movable only in the outer peripheral direction of the container, and the protruding body is restrained by the engaging groove when the lid is removed from the container main body while the lid is fitted. CONSTITUTION: A container 101 is constituted of a container main body 110 and lid 150, and a protruding body 171 is provided on the container main body 110 or one of lid fitting parts of the lid 150, and an engaging part 131 is provided on the other lid fitting part. The engaging part 131 is constituted of an engaging groove 133 and a protruding body-guiding 137. The engaging groove 133 holds the lid 150 while making the protruding body 171 movable only in the outer peripehral direction when the lid 150 is fitted on the container main body 110. The protruding body-guiding part 137 is provided to be adjacent to the engaging groove 133 so that the lid 150 may be introduced to the removing direction by guiding the protruding body 171 in the vertical direction when the lid 150 is removed. When the lid is fitted, the lid 150 is placed on the top of the container main body 110 while inserting the proturding body 171 of the lid 150 in a protruding body insertion part 141, and the lid 150 is turned in the leftward direction, and the protruding body 171 is introduced into the engaging groove 133. |
