The Best Brands of Zero Waste Food Flasks

Ideal for soup (good for hikers and mountain climbers), Circular & Co travel mugs are made from 90% post-consumer recycled stainless steel, for a thermal insulation that keeps drinks hot for 6 hours (or cold for 12 hours).

In three sizes (8oz, 12oz or 16oz). They also have easy one-hand opening, and a 360° sip lid for intuitive drinking from any angle.

Never drink hot liquids straight from wide-mouthed bottles or flasks. 

Do not use for children under 36 months, due to small parts which could be choking hazards. Steel lunchboxes are not microwave-safe (never heat baby or pet food in microwaves). Read our post on food safety for people and pets.

Kept for Life (powder-coated food flasks)

Kept Powder-Coated Food Flasks and Travel Mugs are ideal for the office or travel, with reliable temperature control and leakproof engineering, to take your lunch with you. Made from high-grade stainless steel and coated in pretty powder finishes, these are the ideal replacement to plastic lunch boxes or plastic Thermos flasks.

The dry colour particles are electrostatically applied, then heat-cured over the metal surface. This results in a smooth tactile finish that resists chips and scuffs. The vacuum sealing also keeps food hot for 6 hours and cold for 12 hours (same for the matching drink bottles). Whereas the travel mugs keep the contents hot for 3 hours, and cold for 6 hours.

An investment in this little beauty, means your homemade brew or soup stays warm through meetings, even if they over-run! And your water stays chilled in the matching bottle, from the train to the trail. The food flasks even include an integrated spork (combined fork/spoon) for easy eating. A veggie stew on a cold walk, a pasta salad in the park or plant-based yoghurt and fruit on the school run. All possible!

Sold in easy-to-recycle gift packaging, this makes the ideal eco-friendly gift idea for a loved one too. You can buy one product (food flask, travel mug or water bottle). Or bundle all three, a wonderfully thoughtful gift for those you know, or even yourself!

Care is simple: just hand-wash with warm soapy water, then air-dry (with the lid off). Avoid harsh scrubbing (and avoid dishwashers) to preserve the powder-coated finish. A soft bottle brush and occasional baking soda rinse, helps to keep flavours fresh.

Black + Blum Lunch Boxes and Food Flasks

Black + Blum is a quality brand of stainless steel lunch boxes, insulated food flasks and reusable water bottles. Each purchase is designed to last years, then is easily recycled.

The 1 litre lunchbox is made from quality stainless steel. It includes a leakproof sauce pot and a stainless steel fork.

The meal prep containers are ideal for the freezer and dishwasher, good for food storage and eating on the go. They are also leakproof and airtight (the maker says these are unique in being microwave-safe due to special design, but don’t use with metal utensils, or just use for food storage). 

The insulated lunch bags (wipe-clean only to avoid microplastics leaching from machines) are made from recycled plastic bottles. When stored upright, the roll top and welded lining construction is leak-proof and the insulated inner lining will maintain temperature of foods for a little-while. Easy to carry, even on bicycle handlebars!

The Insulated food flasks can keep food hot for 6 hours, or cold for 8 hours.  Includes a spoon for soup, and an elastic strap (wipe-clean only). Sold in a zero waste gift box. The Explorer Flask includes two steel cups and a carry handle, ideal for camping.
