I am affraid I will disappoint you because this is my own terminology. I call it "just is case" because it contains just in case things I need. I put them all together because I found out that, when I transfered things from one bag to another, I would usually forget some things anyway. So I decided to keep them all in one place.
When I have to travel - does not matter, abroad or to the town centre - I move my "just in case" bag from my briefcase to my rucksack, or another bag I decide to carry, and I know that I am quite well covered for most problems. If I forget something, it usually only causes inconvenience, not live or death situation, but it is still annoying. This is the purpose of the bag - minimise this annoyance, partically in urban areas.
This is what I keep in my "just in case" bag: ballpoint pen, notes, mobile phone battery charger, microphone to record telephone conversations (I do need it), transparent adhesive tape, some medicine (heartburn, cold, throat pain, pro-plus), compact deodorant, lighter, shoe cleaning cloths, adhesive bandage for wounds, chewing gum, these small keyring lights (replaced Mini-Maglite), moisturising lipstick, soft wire (I was locked outside my office a few times and did not know the code for the door, so I opened the door using this wire), Swedish firesteel and cotton in plastic box from photo-film (I do not know where to keep these things at home without losiing, but will definitely move them out of my bag), shopcards, credit cards, passport size photos, stamps, haircomb, staples, tissues and SAK SwissChamp. Wow, I did not know I have to many things there!
It is a normal stationery bag for pupils at school. I would not say it is "survival bag", but it lets me get through small problems with less hassle. Even if I am at home and need a medicine, I will take it from "just in case bag" because I know where to find it. So, I replace the stock quite regularly.
