Food Flasks and Insulated Food Jars

A food flask makes it easier to eat and drink well when you’re away from the kitchen. Hot lunch at work, a quick meal between school runs, or a travel flask for hot drinks on the commute. Our collection features Thermos vacuum-insulated food jars, travel mugs, water bottles, and larger options for all-day use.

Travel Flask: Choose Your Match

• Packing meals? Start with a vacuum-insulated food jar.
• Carrying drinks? Consider a travel coffee flask or travel tea flask style.
• Buying for kids or smaller serves? Look at compact sizes.
• Unsure on size? Jump to the capacity guide below and pick a range first.

Why Use a Vacuum-Insulated Food Jar?

Vacuum insulation helps reduce heat transfer, which can help food and drinks stay hot or cold much longer than in a regular container. For workdays, school days and weekends out, that means fewer compromises. Hot food is more enjoyable, and drinks can stay warm while you get on with your day.

Shop Food Flasks by Use

Food flasks for hot food

If you’re shopping for hot food flasks, look for a jar shape that suits the meals you actually pack. Chunky soups, noodles and curries are often easier with a wider opening, while smoother soups can work well across many jar styles.

Travel flasks for hot drinks

For a travel flask for hot drinks, convenience wins, and how you sip matters. Consider whether you want a cup-style lid for quick sips, a mug format for desk comfort, or a tumbler shape that’s easy to carry and store.

Family-friendly options

If you’re buying for kids or prefer lighter carry, compact jars and bottles are often the simplest win. Thermos Funtainer items in our collection include smaller vacuum-insulated food jars and drink bottles, which can suit snacks, smaller servings and busy morning routines.

Choosing the Right Size

Choosing the right capacity up front saves time and usually leads to a better everyday fit.

• 290–355 ml: Best for kids’ portions, snacks and sides, or a smaller drink bottle.
• 350–530 ml: A strong everyday range for travel cups and mugs and compact meals.
• 710–800 ml: Better for bigger lunches, long shifts, or when you don’t want to top up.
• 1–1.9 L: Best when you want extra on hand for long outings or shared use.

What to Look for in a Travel Thermos Flask

• Opening and eating and sipping style: Look for a food-jar opening that suits your meals or a drink lid that suits your sipping habits.
• Carry style: Consider whether you’ll keep it upright in a bag, in a cup holder, or on a desk.
• Accessories: If you often eat away from the kitchen, a food jar with a spoon can be convenient.
• Cleaning routine: If you meal prep a lot, prioritise shapes that are easier to wash and dry thoroughly.

How to Care for Your Food Flasks

To keep your flask fresh, rinse soon after use when you can, wash thoroughly, and let it dry completely before storing. If you’re storing it between uses, it helps to store it with the lid not fully tightened so any residual moisture can evaporate.
