PROBLEM TO BE SOLVED: To provide a food pack cover stopper structure which can close or open a cover with easy operation and which can surely join a container with the cover without a means such as a stapler, an adhesive tape or welding by an electric iron. SOLUTION: A flange edge 4 formed flat and wide extending outward from the bottom peripheral edge of a cover body 2 and a long flap 5 in the front side of the flange edge 4 are integrally and simulatenously formed. Meanwhile, on a flange 6, which is formed flat and wide extending outward from the upper peripheral edge of a container main body 1, a gap 7 in which the long flap 5 is inserted is povided on the upper face which touches the lower face of the flange edge 4 of the cover body 2 when closed, and also short flaps 8, 9, which, coupling with both sides of the gap 7 to catch the long flap 5, are provided, being formed integrally and simultaneously so that the long flap 5 and the short flaps 8, 9 can fit each other. |
