The compact and lightweight JNL series thermos mug stands out for its special comfort in use. It can be used even on the go thanks to the original lid-plug design. The thermos mug is easy to open and close with one hand - left or right. To open the thermos, simply press the button on the front of the lid - the top lid automatically flips back 180 degrees, locks in the open position, and does not tip over when drinking. The smooth-shaped spout with a small pouring hole allows you to control the flow of liquid. The thermos can be placed in a handbag or backpack without fear of spilling the drink - a special locking ring is provided on the lid-plug. Despite its large capacity, the thermos mug weighs only 210 grams, and the base diameter allows it to fit in car cup holders and bicycle holders. The main advantage of the thermos is its record-long temperature, taste, and aroma retention of beverages. Liquids stay hot for at least 12 hours or cold for up to 24 hours thanks to efficient vacuum insulation. The high heat-insulating properties of the thermos mug are achieved through the use of innovative technologies from THERMOS, premium materials, and design features. All materials used in the thermos are safe, environmentally friendly, heat-resistant, impact-resistant, BPA-free, and do not emit or absorb odors. The food-grade corrosion-resistant 18/8 AISI 304 Stainless Steel used in the production of the thermos is inert to its contents and does not affect the taste of beverages. The seamless welding technology makes the walls of the body and flask completely smooth, so no beverage residues are retained on them, and their aromas are not absorbed. The thermos's seal and gasket are made of heat-resistant and durable food-grade silicone for airtightness. The excellent appearance of the JNL-506 ASWH thermos mug is accentuated by the durable ash-white coating. The thermos mug is easy to maintain. The hygienic lid-plug can be completely disassembled for thorough cleaning of all parts. The THERMOS® JNL-506 ASWH thermos fully complies with the International Quality Standard EN12546-1:2000.
