Primus Food Flask

Keep food warm for longer with vacuum insulation

A food flask makes it easier to bring hot food to work, school, the mountains or the forest. Primus food flasks are built with double-wall vacuum insulation that helps food keep its temperature for longer, while the stainless steel construction makes them durable enough for both everyday use and outdoor life.

The wide opening makes a food flask more practical for food than a narrow vacuum flask. It becomes easier to fill it with soup, stew, pasta or salad, and the same opening also makes it easier to eat directly from the container and clean it afterwards.

When hot drinks are more important than food, vacuum flasks serve a different purpose, as they are designed for coffee, tea, hot chocolate and other drinks that need to keep their temperature for longer.

Benefits of Primus food flasks:

• Keep food hot or cold for longer, depending on the model, amount of food and outside temperature.
• Robust stainless steel construction for everyday use, outings and longer trips.
• Wide opening that makes it easy to fill, eat from and clean.
• Practical format that works in a backpack, work bag or picnic packing.
• Suitable for soups, stews, pasta, rice dishes, salads and other meals on the go.

The difference between a food flask and a regular vacuum flask

A food flask and a regular vacuum flask are often based on the same basic idea: insulation that helps the contents keep the right temperature. The difference is mainly in the shape. The food flask has a wider opening that suits food, while a vacuum flask usually has a narrower opening that is better for drinks.

For solid food, soups and stews, the wide opening makes a big difference. It makes both serving and cleaning easier, especially when the food has a thicker consistency. For water and cold drinks, water bottles are often a more convenient option, as they are easier to drink from often and work well during training, commuting and hiking.

A food flask is best suited when the meal is already cooked and needs to be kept hot or cold until the lunch break. It makes it possible to eat proper food even when there is no kitchen, restaurant or way to heat the food on site.

Which food flask suits you?

Choosing a food flask is mainly about portion size and how it will be used. A compact model works well for lunch at work, children’s outings or shorter day trips. A larger food flask provides more volume when the meal needs to last longer, when several people are sharing or when food needs to come along on cold days outdoors.

For coffee or tea on your way to work, travel mugs are more practical than a food flask, as they are made for drinks and are easier to use in the car, on the train or between activities.

Popular models:

• Flinta Insulated Lunch Jug 0.55 L: spacious stainless steel food flask for hot or cold meals during day hikes, family outings and lunch breaks. The wide opening makes it easy to fill, eat from and clean.
• Mat-Termos Flaska 1.2L: larger insulated food flask for soup, stew or hot drinks when more volume is needed. The robust construction suits longer outings, cold days and trips where the food needs to last longer.

Food flask for children, work and outings

A food flask can be just as useful in everyday life as on a trip. For school, work or activities, it makes it easier to bring homemade food without depending on a microwave or serving facilities. For children, a compact food flask is practical when lunch needs to be easy to eat and the packing must not become too heavy.

On outings and hikes, a food flask gives more flexibility during the day. The food can be prepared at home, packed hot or cold and eaten when the break suits. This reduces the need for disposable packaging and makes it easier to bring meals that are actually filling.

Thoughtful design for easy use

Primus food flasks are made to be easy to use often. The wide opening makes it easy to add food, reach the contents with a spoon and wash out the container afterwards. Stainless steel provides a durable surface that can handle everyday use, packing and outdoor life.

The right food flask depends on how much food you want to bring and how long it needs to keep its temperature. A smaller model works well for a regular lunch, while a larger model is better for longer days, cold conditions or when the portion needs to be more substantial.

Frequently asked questions about food flasks

Here are answers to common questions about use, cleaning and choosing the right size.

How long does a Primus food flask keep food warm?

How long the food stays warm depends on the model, amount of food, the temperature of the food when the flask is filled and the surrounding temperature. A food flask usually keeps heat best when it is properly filled and the food is very hot from the start.

Can I wash my food flask in the dishwasher?

Hand washing is usually best for preserving the insulation, lid and surface treatment for longer. Warm water, dish soap and a dish brush are usually enough for daily cleaning.

What size food flask should I choose?

A smaller food flask works well for lunch, children’s outings or shorter trips. A larger model is better for generous portions, longer days outdoors or when the food will be shared between several people.

Can I use my food flask for drinks?

A food flask can be used for some drinks, especially soup or broth, but the wide opening is mainly adapted for food. For coffee, tea and other drinks, a vacuum flask or travel mug is usually more practical.
