Milk and a bumpy road

You want to take food, that doesnt keep, with you, when you are away for a couple of days. For example if you go to a summerhouse.

Milk can come in cartons that look like this.

If the road to the summerhouse is bumpy, the cooler box will be full of milk splashes, when you arrive.

An easy solution is a so-called foldback clip.

Foldback clips are meant for sheets and blocks of paper. You can buy them in book stores and stores with office supplies.

It fits nicely over the opening of the carton.

It holds the milk in the carton even when it sloshes around.

But it cannot hold the milk in the carton if it lies down or is turned on its head. If you have that challenge, you need to find another solution.
