I'm glad you all like the idea, and I can't wait to see what you all do with it. I know for sure some of you fabricators are going to one-up it and make something really awesome. Have at it.
someone asked if it is a screw top, not it's not, just a friction fit. That's what I meant when I said we were brainstorming for better ideas. Then Skip (thatismytruck) found screw-on aluminum containers. If they are the correct width (they need to be narrow), that would be much better, because then things can rattle around in there and not push the cap off.
Also, a friend suggested putting a spring on the inside that keeps the cap on. In other words, you would have to pull the cap off against the spring's tension, and push the cap aside to access the contents inside. Then align the cap, and it would almost be self closing from the spring's pull. Know what I mean?
One of the reasons I like the Never Dull container is that when I've been at Rat Rod car shows, the guys often use old Marvel Mystery Oil cans or what-not as catch containers. So I thought this was following in that tradition.
thanks again
