Patent attributes
When a turning portion on the front end side of the cover is turned in one direction, a turning-portion engagement part disposed in the turning portion engages with a container main body-side engagement part so as to close the cover. When the turning portion of the cover is turned in the opposite direction, engagement between the turning-portion engagement part and the container main body-side engagement part is released. When the turning portion is kept turned in the opposite direction, a turning-portion opening-operation auxiliary portion disposed in the turning portion abuts on a container main body-side opening-operation auxiliary portion and the cover can be pressed up with a weak force by the principle of the lever.
