Here's a great example of how clever design features can be packed into something as simple as a bottle. Billed as "The glue bottle that sucks," FastCap's GluBot shows that by analyzing how things are actually used and making some clever changes, one can vastly improve the end user's experience.
Let's look at your standard bottle of Titebond. When you slide the nozzle shut, a little plastic "tongue" occupies the slit, pushing a small amount of glue residue outside the tip. I always thought that was neat, as you just peel off the dried residue next time you use it. But the GluBot goes well beyond this in terms of convenience, and gets around the problem a finish carpenter might encounter, where he's trying to glue a piece of crown molding up near the ceiling and doesn't have the clearance to turn the bottle upside down.
Who better to describe the GluBot's design features than someone who uses it every day for work? Here's Ron Paulk running down the list of design wins, and showing you the only thing that's better than the standard GluBot:
