PROBLEM TO BE SOLVED: To prevent a latch working as a hinge from coming off when a double hinged cover is opened in one side. SOLUTION: A shaft 13 is provided on each outer face of the side wall 12 facing each other or a container main body 8. The upper opening 9 of the container main body is covered with a cover body 10. A latch 15 is provided at each corresponding position of the shaft on the cover body 10. By this, the cover 10 can be opened from a side desired. A protrusion 20 for preventing the shaft from coming off is provided on the shaft locking face of the fitting protrusion 18 at the tip end of the latch 15. A protrusion 22 for regulating a rotation in an angle bigger than the same required of releasing the latch from the shaft 15 is provided between the latch 15 and the cover body 10. Because the protrusion on the side working as a hinge when the cover 10 is opened in one side pushes the latch 15 in a locking direction, the latch 15 is fitted with the shaft and the cover 10 does not fall. |
