I would argue that pretty much anything you would put into your refrigerator is contained inside packaging. Sometimes that packaging is just a simple plate.
I put a cat in the refrigerator more than once - for some reason, my cats loved sitting there for few mintues long when there were young. There were definitely not packaged.
I put a lot of fruit and vegetables in my fridge with no packaging. Why would I contain them?
While arguably not correct, is there any particular reason to downvote this? I think it's a fairly valid point
