thermoTANKA History

ECOtanka designed the thermoTANKA in 2008 and made the first bottle in 2009.  Since then everyone liked the design and copied it, you can now see our design everywhere!!  The thermoTANKA was originally designed to keep drinks colder longer due to the insulation function of the vacuum, but people like it so much they now keep your drink hot.  One bottle for summer and winter!

ECOtanka values quality and safety. In order to make sure that our products are 100% safe and long-lasting, we test all of our material parts that come in contact with liquid or food.   Material testing is done in stages with the first major test completed by a certified independent testing lab, this is completed every 4-5 years.  The second test is completed by the wholesale supplier of the raw material or the main production factory a certified independent testing lab.  The third test is carried out by our own team using a number of methods as follows:

1. A stainless steel liquid colour test to confirm the stainless steel type.
2. A spectrometer test which takes an analysis of the material makeup to verify its quality.

The materials we test are as follows:
- Stainless Steel for Bottle material
- Silicone for Seal material
- PP for Plastic Lid material
- Stainless Steel for Lid material
Our testings are mostly as per EU standards. From time to time, we carry out FDA testing as well.  As testing samples, we provide one product type for each material category.

Summer Tip:

To make a drink that stays cool for hours in summer, simply fill your bottle with ice cubes, top with water, then fit a kooler cover over your bottle.  All ECOtanka bottles have a special wide mouth, allowing ice cubes to be used for an instant cold drink.  Please do not place your tanka in the freezer.
