The FJK series thermos bottle is a great gift for lovers of carbonated drinks. The special design of the lid-cork allows you to safely open the filled thermos even after accidentally shaking it - the cork will not fly out, and the drink will not spill rapidly over the edge. The lid-cork consists of two parts with a pressure release system that forms in the closed container when storing carbonated liquids. The thermos bottle is easy to open in two steps - first, you need to slightly turn the cork counterclockwise to equalize the pressure, and then completely unscrew the cork. The vacuum insulation, created using a unique technology, protects the drink from heating in the heat, thereby minimizing changes in pressure inside the bottle, and keeps it cool for up to 24 hours. Condensation does not form on the body of the thermos from cold liquids, so the thermos bottle does not slip in the hand. The rounded edge of the neck provides special comfort when drinking from the thermos bottle. Thanks to its slim shape, the thermos bottle is convenient to hold for both women and children. The FJK-500 SL thermos with a volume of 500 ml is compact and lightweight, weighing only 200 grams. The dimensions allow it to be easily placed in a bag or side pocket of a backpack, and the base diameter fits car cup holders and bicycle holders. All materials used in the production of the thermos are absolutely safe, environmentally friendly, and suitable for recycling. The food-grade corrosion-resistant 18/8 AISI 304 Stainless Steel used in the production of the thermos is inert to the contents, does not affect the taste of the drinks, is resistant to temperature changes, and provides the thermos with strength. The screw lid-cork is made of modern copolymers that are BPA-free, heat-resistant, mechanically strong, and durable, they do not release or absorb foreign odors. The seal responsible for the thermos bottle's tightness is made of heat-resistant food-grade silicone. The seamless welding technology makes the walls of the thermos completely smooth, so residues of drinks do not linger on them, and their aromas are not absorbed. The thermos is easy to clean and maintain. The vacuum-insulated thermos can be used for storing cold sports drinks, smoothies with ice, warm drinks, but it is recommended to drink hot drinks not from the neck, but using a cup or glass to avoid burns. The stylish appearance of the thermos bottle is created by a unique silver-colored coating. The THERMOS® FJK-500 SL model fully complies with the International quality standard EN-12546-1:2000.
