The difference between a food flask and a regular thermos

A food flask and a regular thermos serve different purposes, though both are designed to keep contents hot or cold for hours. The key difference lies in their construction and intended uses.

A food flask has a wider opening, making it easier to fill, eat from, and clean. It's designed for solid foods like soups, stews and pasta, while a regular thermos is built to keep drinks hot or cold, featuring a narrower opening to minimise heat loss.

If you need a solution for hot meals during long days outdoors or at work, a food flask is the best choice. For keeping coffee or tea hot for hours, a classic thermos is more suitable.

Which Food Thermos is Right for You?

Primus offers several food thermos models for different uses. Choose the size and design that best suits your needs, whether for short day trips or extended expeditions.

Lunch Boxes & Food Flasks for Kids

Having a reliable food flask or lunch box for children makes it easier to pack homemade, warm meals for school, outings, or activities. Primus offers convenient and durable food flasks designed for small hands and easy opening.

Some Primus food flasks, like the TrailBreak Lunch Jug, are especially practical for kids thanks to their compact size and easy handling. The wide opening makes filling and eating straightforward, while the vacuum-insulated construction keeps food warm throughout the day. With a leakproof design, you can trust that nothing will spill in their backpack.

Thoughtful Design for Easy Use

Primus food flasks are crafted with the user in mind. The wide opening allows for easy filling and eating directly from the flask without extra utensils. Additionally, the powder-coated surface is slip-resistant, providing a secure grip even in cold and wet conditions.
