do they make a cap for klean kanteen sippy?

I know you can get the flat cap - but requires that you unscrew the sippy tip adaptor. For travelling, is there a cap I can just stick on the adaptor? Would make the bottle much more useful... maybe I am missing something?

The caps for Avent bottles fit perfectly, if you have any of those around. The caps for Avent sippy cups do NOT fit, though.
