Patent ID: 7452145

Claim:
A hinge structure of a container for rotatably pivoting a cover member on a base member comprising: at least a first bearing portion provided on the cover member and having a first center hole; at least a second bearing portion provided on the base member and having a second center hole of substantially the same diameter as the first center hole; a hinge pin inserted into the first center hole of the first bearing portion and the second center hole of the second bearing portion for aligning said at least a first bearing portion and said at least a second bearing portion on a same axis so that the cover member is rotatably pivoted on the base member; a first stopper provided at a first position on the base member or the cover member for facing an end of the hinge pin with a predetermined gap; and a second stopper provided at a second position on the base member or the cover member so that a part of the second stopper faces another end of the hinge pin with a predetermined gap in a natural shape, and having elasticity to be deformed when the hinge pin is inserted into the first center hole of the first bearing portion and the second center hole of the second bearing portion by applying a pressure thereto and to be recovered by displacement radially with respect to a longitudinal axis of the hinge pin to a natural shape when the pressure is released so as to prevent escape of the hinge pin from the first center hole of the first bearing portion and the second center hole of the second bearing portion.
