I have a couple of insulated plastic tumblers (double-walled, I think is the term). Anyway, the tumblers have come unglued due to frequent trips to the dishwasher, I guess. Rather than throwing them away, I would like to reglue the 'double-wall' pieces back together and keep using them. Does anyone know of any glue that would be food-safe -- since they will be used to hold beverages? Any information concerning this will be greatly appreciated.

Thank you,
Kat

I can absolutely assure you, you will never find a food safe glue.

Epoxy is the strongest, but hot cycles of the dishwasher will trash anything pretty quickly. The epoxy probably won't be in much contact with the drinks, depending on where you glue the pieces. Enough is good, too much is not better!
Good luck,
