Coffee Containers
Coffee containers with lids are the travelers best friend.Fill the the cans with emergency supplies, such as toilet paper,
minus the central cardboard core.you can include water proof matches,packets of hot cocoa or coffee. Work gloves
a small wax candle,a warm knit hat,an emergency blanket.You could also include candy bars, bandages/first aid supplies
or sewing kits.The can could also be used for an emergency bathroom. It can be capped & discarded after use.
Hope this gives you some ideas.I am sure there are lots more.
