American English: Hose (possibly garden hose, but typically just hose) Race Car Fridge (only because it is shorter. Refrigerator is also commonly used) mini-fridge (always fridge here, never mini-refrigerator) Packed lunch if you packed it at home, boxed lunch it if is provided by a caterer at some event or possibly purchased at a shop.

The first of each. I’m from the UK.

I'm Dutch and my English has evolved from all over the place, but here is what I would use: Garden hose Racing car Fridge Mini Fridge Packed lunch for the actual food, lunch box (so the other way around) for the container it goes in.
