These double-walled, vacuum-insulated food containers from Klean Kanteen® keep their contents warm for up to 8 hours or cool for up to 22 hours. The design of the lid makes it easy and safe to close and open: its screw cap consists of three individual parts (sealing ring, rotating ring, silicone seal) that can be easily removed for cleaning. Thanks to the rotating ring, the lid cannot get stuck in the thread and can always be opened very easily with a small twisting movement. The seal is made of silicone, the twist ring and thread are made of BPA-free polypropylene.

Transporting food, especially freshly prepared dishes or even soups, is often a risky business, especially if you want to avoid the usual plastic containers. Stainless steel food containers are an absolutely (soup) leak-proof and far more durable alternative. These from Klean Kanteen® can be closed airtight and leak-proof by means of an external screw thread and are therefore equally suitable for transportation and storage. And so that you know what the containers contain inside, protected from light, they can be labeled with grease pencils.

The Californian family business Klean Kanteen® offers clean alternatives to disposable cups and bottles with its stainless steel containers. What began with a drinking bottle has developed over ten years into a broad repertoire of containers for transporting food, made without aluminum and bisphenol-A (BPA), but from tasteless and odorless stainless steel. Unlike aluminum and plastic, stainless steel is an inert material that neither reacts chemically with food nor releases particles. Containers made from this material are extremely stable and durable, and they also come in a functional and visually appealing design. Klean Kanteen® has the articles manufactured in China and regularly inspects the production facilities there to ensure that Klean Kanteen®'s environmentally friendly standards and working guidelines are adhered to. As a member of "1% for the Planet", Klean Kanteen® donates at least one percent of its sales to environmental protection projects or educational support through non-profit organizations. At the beginning of 2020, the company joined the non-profit organization "Climate Neutral". The aim is to reduce CO₂ emissions to a minimum throughout the company. Even simple measures such as the use of green electricity, video conferencing instead of business trips and reusable solutions in the canteen can help. The first visible step for customers is to do without packaging.

Klean Kanteen® only uses 18/8 stainless steel, and this in a thicker thickness, which makes Klean Kanteen® products significantly more robust than many other stainless steel containers. They can therefore withstand a lot, but are still light enough for use on the go. The threads are also largely made of stainless steel. This contributes to the longevity of the containers. The bottle caps are fitted with silicone seals, which are also used in medical technology.

To ensure that the containers can be used for a long time, they must also be easy to clean. Klean Kanteen® therefore manufactures them with rounded "corners" and smooth, wide threads. On the inside, the surface is electropolished and so smooth that dirt cannot stick easily. And if something does dry on the inside, the wide openings make it easy to reach. Another practical feature is that the stainless steel containers can be cleaned in the dishwasher.
