So I have a bottle similar to this one, and I wish for a small snack container that opens in a similar way.

I want something that opens with a button push, revealing an opening wide enough to dump loose granola, mixed nuts, or trail mix into my mouth.

But also I want it to keep dirt and machining coolant sprays out, so in want the lid to cover the entire top when it's closed like the bottle is covered, and I want to be able to operate the spring loaded lid without touching anything that I then have to eat from.

I have yet to find a good solution.
