Air-Tight Dog Food Storage Container

My girlfriend is looking for an air-tight storage container for about 30 lbs of dog food. She wants it to be white (not transparent), rectangular and air-tight without a screw-off lid. I can see exactly what she wants, but I can’t find one—anywhere!

These were the closest containers we could find, but none of them fit the build:

I wonder, if I’m looking for the wrong thing. Maybe I should be searching for rice or grain storage?

My girlfriend ended up purchasing the IRIS Storage Container. It’s not the most attractive thing in the world, but it gets the job done.
