Our aim is to constantly optimize our FLSK products. This is why we proudly introduced the second generation of FLSK to the market in the beginning of the year. For the volumes of 350 ml and 500 ml we used newly engineered, softer silicone rings. As it now turns out, this has the consequence that a high pressure builds up inside the bottle due to the transport of carbonated beverages. This can cause the lid to come off the bottle neck jerkily when unscrewed. You can imagine this effect similar to a champagne cork.
Important: This is not a product recall but a product warning. The so-called "champagne cork effect" currently occurs in approx. 5 % of our sizes 350 ml and 500 ml.
Don't worry: the FLSK does not explode.
You know from the FLSK or conventional bottles with carbonated drinks that some carbon dioxide can escape when opening them at first. Due to the softer silicone ring, the carbon dioxide remains trapped inside the FLSK until it is completely opened. Therefore, the entire pressure of the bottle is released at once when the lid is being removed and not gradually.
Of course, we want you to be able to enjoy carbonated drinks from your FLSK. Therefore, we are already producing new silicone rings with full speed. In order to receive these, please simply fill in the form below. If you prefer to pick up your new sealing ring from your trusted dealer, you can do so as of September.
Please enter your address in the form below. We are already producing the new silicone ring, which we will send you by post at the beginning of September. In the meantime, we kindly ask you to avoid filling carbonated drinks in your FLSK.
