leak proof lid with stoneware container-- from Refrigerator to oven to dining table

criteria:
- Leak free covers for round and rectangular stoneware containers
- Food storage line aimed for “from storage to table” 
- Sleek lid design ensured the pattern on the container can be as visible as possible 

proposal:
- After studying several market samples, making and evaluating a couple of prototypes, the final solution was to apply the similar mechanism as wine bottle stopper. 
- Different number of silicone blades for different capacity of containers. Adjusted the tolerance based on the container capacity.
- Minimal design goes well with any pattern on the containers.
