Welcome Clive, I tried utilizing my pocket tin for a small drinking/boiling tin. First is the problem of where to put all the neccessarily small items. I wound up shoving everything into my already loaded pockets. The small drink hardly seemed worth the effort. Next I fashioned a cup from aluminum foil. This gave me the volume, but wasnt very stable balancing on my German pocket Esbit stove. I finally settled on my Tin Cup for it's intended use. Since I was going to carry it along anyway, I nestled a small can of caribou meat, a satchet of salt, pepper, sugar and tea and topped it with a n additional coil of snare wire. A P-38 can opener was taped to the meat tin. Finally the entire affair was secured with Ducktape. Admittedly this isn't for daily carry in the city or for travelling with only the pocket tin.Then I would use the tin foil, or locate one of the collapsing cups.<br><br>
