<P>PROBLEM TO BE SOLVED: To provide a sealed container, which exhibits a loosening prevention effect without increasing the dimensions of a fastening member. <P>SOLUTION: The sealed container 1 is configured such that a container body 2 and a cap closing an opening 4 formed in the container body 2 are fastened together by means of screws. In the sealed container, the threads 12 and 23 of the screw of one of the container body and cap and the thread grooves 13 and 25 formed on the other side are engaged with each other. When the cap 3 is screwed along the edges of the threads 12 and 23 and the thread grooves 13 and 25 up to the position where the cap 3 is completely screwed up to the container body 2, the first projection 14 of the thread 12 and the second projection 26 of the thread groove 25 are locked with each other. When the two projections are locked, the opening 4 of the container body 2 is sealed with the cap 3 by virtue of the locking force. <P>COPYRIGHT: (C)2011,JPO&INPIT |
