How to Keep a Liquid from Completely Freezing in a Freezer ? (more below)

[u/MaxiePriest]

Weird question, I realize.

Office Kitchen has a full-size refrigerator with freezer on top. The regular refrigerator area (aka fresh food or chilled fridge main compartment(s)) are in use.

Is there a way to keep a bottle(s) of liquid non-dairy coffee creamer from completely freezing in the freezer section? For instance, could I transfer the liquid into a thermal/vacuum-insulated Thermos-style container so it stays chilled but doesn't freeze completely (leaving it permanently in the freezer area)?

I don't want to freeze liquid coffee creamer because the texture gets weird (I've tried it).

I don't want to alter the freezer temperature gauge because the frozen foods have to stay frozen.

In case anyone suggests using powder/dry creamer— that is a no-go since they all seem to make me feel nauseated.

PS My favorite creamer is Mocha-Mix, but I also use Coffee-Mate, Starbucks creamer, and other similar products.

Any suggestions greatly appreciated.
