PROBLEM TO BE SOLVED: To provide a lid fastener which can reliably fasten a lid body detached from a food container to the whole of a circumferential direction, makes the food container portable and has high versatility applicable to various food containers.SOLUTION: A lid fastener 1 includes: an opening 11 capable of accepting a flange 2f of a food container 2 outer circumference; outer edges 13 which form a cross section shape capable of fitting to the flange 2f and form a hollow space 12 capable of housing the food container 2; and a flexibility promoting part 14 which promotes the deformation of the outer edges 13. External shapes of the outer edges 13 preferably form arc shapes or horseshoe shapes and it is preferable that guides 15 for guiding the food container 2 are formed at an outer edge 13 tip end. Furthermore, the flexibility promoting part 14 has a thin plate shape and it is preferable that the outer edges 13 are extended from both ends. |
