The durable and practical ROB series thermos cup has a number of features that provide maximum comfort when using it. The volume of the thermos cup is designed for two full cups of drink (500 ml). Liquids stay hot in it for at least 12 hours or cold for up to 24 hours, remaining tasty and aromatic. The thermos cup is easy to open and close - just turn the screw cap one turn counterclockwise or clockwise. It is convenient to drink from it thanks to the rounded edge of the neck. For attaching to a bag or backpack, as well as for carrying in hand, a sturdy folding ring is provided on the cap. It securely attaches to the cap body. When folded, the ring integrates into the cap and fits snugly against it. To protect the base from impacts and for stability on smooth surfaces, the thermos is equipped with a removable silicone base. All materials used in the thermos are absolutely safe for health, 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 and does not affect the taste of the drinks, is resistant to temperature changes, and provides the thermos with strength. The seal responsible for the thermos cup's tightness is made of heat-resistant food-grade silicone. The screw cap is made of modern copolymers that are BPA-free, thermally resistant, mechanically strong, and durable, do not release or absorb foreign odors. The high thermal insulation properties of the thermos cup are provided by the design features, premium-class materials, and innovative technologies. The unique technology of creating a deep vacuum in the interstitial space of the thermos ensures a long temperature retention mode for the contents. Thanks to the vacuum insulation, the thermos body does not heat up from hot drinks, condensation does not form on it from cold liquids, making it comfortable to hold the thermos cup. The seamless welding technology makes the walls of the thermos completely smooth, so drink residues do not linger on them and their aromas are not absorbed. The thermos is easy to clean. The thermos cup has compact dimensions and a light weight. Despite being made of stainless steel, the thermos cup weighs only 300 grams. The stylish and original look of the thermos cup is complemented by a durable and practical sand-colored coating. The THERMOS® ROB-500 SDBE model fully complies with the International Quality Standard EN-12546-1:2000.
