Food Flask Buyer’s Guide

Material

The best food flasks are made from durable and quality stainless steel which is double walled to provide optimal thermal insulation. Make sure the metal is food grade and also the lid which will double as a bowl or cup for the contents.

Insulation

Almost all food flasks offer temperature control for hot and cold food and drinks, but time periods do vary with some only providing around 6 hours of temperature maintenance whereas there are other brands who more than double this.

Features and Extras

Many food flasks offer a foldable spoon tucked away in the lid, however not all are full size.

If you like chunky soups or stews or want to carry pasta, then make sure you choose a brand with an extra wide opening. These are simple to fill, to pour out and much easier to clean.

A handy valve can equalise the pressure between the difference in temperature inside and outside the flask. This makes it easier and safer to open, ideal for kids who may struggle with a strong vacuum seal.
