[SML] What is this cap called?

[taco at peak.org]

Have you looked at all the water and drink bottles that are littering your campus for a plastic cap that fits? You could have a bucket sitting there with hundreds of them, and wouldn't need to worry about the chain. 


See, that's the problem - the connection to the cap is riveted on, and 
I can't merely drill out the rivet and rivet a new chain on - inside 
the cap is a rubber seal, and anything that protrudes into the cap 
will interfere with the rubber seal, and in turn poke into the 
connectors... it would need to be flush, like the factory-applied 
rivet that was (is) there now. Replacing the chain is the hope, but I 
can't figure out a way to do that without using user-serviceable 
mechanical fasteners on the cap side.
