We created Blockhütte because we were tired of leaky lunch containers and cheap materials. What started on our travels turned into a mission: build products that truly last and make a difference – for people and the planet.”
— Nils & Malte, Founders
100% Leakproof – Guaranteed
Tired of soggy bags and leaking lids?
We get it. That’s why our food flask features a precision-engineered thread and a thick, one-piece solid-seal gasket. The result? A lid that closes securely every time – no leaks, no mess.
And just in case, we’ve included a free spare seal.


A Climate-Conscious Choice
Since 2021, every Blockhütte product has contributed to climate protection. We proudly partner with ClimatePartner to offset all CO₂ emissions from production and delivery.
Hot Food for 14 Hours & Cold for 19
This is not your average lunch flask. Our advanced double-wall insulation – boosted with an internal copper layer – locks in heat like no other. Your meals stay hot until it’s time to eat. Or ice-cold if that’s your thing.


Fast & Reliable UK Delivery
Your order is packed by the founders themselves and usually ships next working day. Experience the difference – you’ll be surprised how fast we are!
Recyclable & Plastic-Free Packaging
Sustainability is a top priority at Blockhütte!
That’s why we ship your order in a fully recyclable, eco-friendly cardboard box. Even when it comes to packaging, we use as little material as possible – to save valuable resources and reduce waste from the very start.


Food-Grade & Flavour-Neutral
All our lunch boxes are independently tested and certified for food safety every year by DEKRA – so you can be sure you're making the right choice. Every component is 100% free from BPA, BPS and any plasticisers.
Made from high-quality 304 stainless steel, your lunch box is completely flavour-neutral and safe for everyday use. Want to learn more? Feel free to check here.

Hot Food Flask – Truly Leakproof. Truly Reliable.
Tired of so-called “leakproof” food flasks that end up spilling soup in your bag? So were we. And plastic lunch flasks weren’t the answer either – full of synthetic materials and often laced with BPA or BPS. Not exactly what you want near your lunch.
That’s why we designed the Blockhütte insulated stainless steel food flask from the ground up – with precision-engineered sealing, food-grade materials, and zero compromises.
Every detail has been rethought: from the extended thread to the one-piece solid-seal gasket. And our customers agree – no more soggy backpacks, no more wasted meals. Just peace of mind, every single day.
Premium Stainless Steel Thermal Food Container – Built to Last
Self-praise isn’t really our thing – which is why we let independent reviewers speak for us. Trusted platforms like Vergleichen.org have rated our products “Sehr Gut” – Excellent.
Why? Because of the details that matter:
✔ Vacuum-insulated stainless steel body
✔ 100% leakproof screw-top lid with easy grip
✔ A free coconut-bristle cleaning brush
✔ A practical cotton pouch for daily use
✔ Optional custom engraving for gifts or personal touch
And we stand behind our promise – with a 60-day trial and 3-year warranty.
This is more than a hot food flask. It’s the container you’ll reach for every day. Whether you’re commuting, hiking or simply meal prepping, the Blockhütte food flask keeps food hot for hours – and your life hassle-free.
