Gasket-Mounted Plastic Bucket

I need a somewhat durable plastic bucket equipped with gaskets. The bucket is intended for liquid storage. It will be an oval shaped bucket. I need the end of one side of the bucket to snap on and off. If you were to remove the end that snaps off. Then the remaining larger side of the bucket, will have a continuous gasket. This gasket will go along the top rim of the bucket and continue down the now open face of the bucket. If you were to snap the removed end of the bucket back into place, this gasket will seal the two pieces together, and the bucket will be able to hold Water. The smaller piece that is removable will not need any gaskets. The black will be approximately 11 inches by 6 inches wide and approximately 4 inches tall

Requirements:
- Gaskets should be securely mounted to prevent leaks

Ideal skills and experience:
- Experience with plastic fabrication
- Knowledge of gasket installation
- Attention to detail to ensure a leak-proof design
