Making a Collapsible Cooler?

I bought several different sizes of collapsible buckets on Amazon. I live in a care center and am bedridden, so I can't access the community fridge. So when I order drinks from Amazon or cheese, ice cream, etc, from Walmart, I use the buckets. Depending on what I want to keep cold, I'll expand them as deep as necessary, then have an aide fill them with ice.

When I'm done, I ask someone to dump the ice out, so I can thoroughly dry it, then collapse it and tuck it out of the way. I love collapsible items, since I have limited space. Great value for the mony, too! Highly recommend!!
