Duram Paint: poor container ergonomics

I like Duram paints and they are of excellent quality. However, their container design is poor. I was using Duram NuGlo last week and while attempting to open the 1 litre container with a *****driver, I cut two fingers when the *****driver slipped and I injured myself on the rim of the container.. This was not the first time it happened. It is difficult to open the small containers. The larger (10L and 25L) are ergonomically well designed, being easy to open and close, and resuse.
