Free from BPA and phthalates

Whether you're out and about in the city, on a hike or on a picnic - the screw closure for CLASSIC vacuum flasks won't be shaken by anything, as it is 100 % leak-proof. It is included with the CLASSIC vacuum flask, as is the cap with pouring function.

The screw closure of the CLASSIC vacuum flask also ensures that no heat can escape through the opening and that the contents remain reliably insulated. To optimize the heat retention capacity in general, you should preheat the vacuum flask with hot water for approx. 5 minutes before using it. If you want to take cold drinks with you, the same applies - only with cold water. It also generally helps if you close the bottle immediately after use.

The screw closure of the CLASSIC vacuum flask is made of plastic and is free from BPA and phthalates. A silicone sealing ring over the thread also ensures that the closure is leak-proof.
