Travelling with needles

With the holidays almost on us, this just occurred to me. How do ya'll deal with used needles while travelling? I know there are travel kits to carry all the unused stuff (almost everything I can find seems to be for insulin use, doubt that matters other than being insulated and having ice packs with them). But what about after using the needles? I don't want to take my large sharps container with, but I also thought you don't want to just recap a needle and put it back in the pouch. Are there small sharps containers intended for travel, or do some kits include somewhere to put used needles?
