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

Best food jar

This food jar is so cute and works so well. I also love that they thought to include the eating utensil that is both a spoon and fork! I have tested this jar with soup that I had and let it sit for about eight hours. When I opened up the jar steam started coming out and fogged up my glasses! Also I tote bag with the utensil pocket is something that I never knew I needed!!! Super impressed with this company and its products.

Excellent food jar

This is the best food jar I have ever used. I use it to bring oatmeal to work for lunch and the food is always hot five hours into my work day.
The vent plug works great for relieving pressure to ease opening. It cleans up easily and provides a good size serving of food.
I have only used this food jar for about one month, but the finish seems tough and it should last several years with basic care: not much to go wrong and replacement parts are available.
I think this food jar is well worth the price I paid.

Happy with my Blockhutte jar

Excellent customer service. This company values their products and their customers. I was happy with how it kept
my food warm after many hours. When I contacted Blockhutte about some rust spots inside the jar, they responded immediately and sent another one. I didn’t expect this. I just wanted to know how I should clean the stains out. Although I was traveling on another continent with my jar, they waited until I returned home to get back with them. This company stands behind their product! This jar is well insulated and I can clean it easily with the included brush. The canvas cover bag and spork is a very nice touch. A very nice product. Thank you Blockhutte!

Wundervoll!!!

Ich lebe in den USA und suche immer nach Plastik-Alternativen: Endlich bin ich fündig geworden!! Und wie toll, dass ich damit ein kleines deutsches Unternehmen unterstützen kann - besser geht‘s kaum.

Alles super. Die Halterung von dem Löffel ist ungünstig. Es wäre besser, wenn der Löffel direkt am Behälter angebracht wäre.

Die Thermo-Lunchbox ist super ! Einfach zu reinigen und hält sehr gut warm. Nach 6 Stunden ist das Essen noch heiß und nach 12 Stunden noch lauwarm. Ich habe den Tipp befolgt und den Becher vorher 10 Minuten mit heißem Wasser „angewärmt“ . Die Größe ist perfekt für eine Mahlzeit.

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.
