PROBLEM TO BE SOLVED: To surely prevent a cap from becoming loose and opening unexpectedly by vibration, etc. and obtain a good feel that the cap is screwed tight enough when the cap is screwed on a container main body. SOLUTION: This container comprises a container main body 3 having a raised thread 2 for screwing in a spiral shape formed on the outer periphery 1a of a container mouth part 1, and a cap 5 having a raised thread 4 for being screwed on in A spiral shape formed on the inside periphery 5a of the cap. The raised thread 4 for being screwed on is intermittently formed and also between the raised threads 2 for screwing, a raised thread 6 for preventing loosening lower than the raised thread 2 for screwing is formed by connecting each raised thread 2 for screwing. The top of the raised thread 6 for preventing loosening is made to position at an intermittent position K in a condition in which the top of the raised thread 4 for being screwed on does not touch when the cap 5 is screwed on the container mouth part 1. |
