The durable and reliable thermos from the 2550 SS series is made of high-quality food-grade corrosion-resistant steel. Double walls and deep vacuum insulation allow you to keep the temperature of drinks, hot or cold, for over a day. The steel is inert to the contents, so the drinks remain aromatic, preserving their taste. The thermos is convenient to use thanks to the screw cap with internal guide grooves - it does not need to be completely unscrewed when pouring a drink into the lid-cup, thereby minimizing the influence of the ambient temperature on the thermos contents. Flow indicators are provided on the top of the cap. The double-layer lid made of stainless steel and heat-resistant plastic has a wide rim for easy handling of the lid-cup with a hot drink. For comfortable carrying, there is a folding handle made of durable plastic with metal fastening. The relief on the inner side of the handle facilitates carrying the filled thermos in hand. The thermos design is reinforced with elements made of durable plastic, and the side upper and lower stoppers secure the thermos in a horizontal position. All materials used in the production of the thermos are safe for health, environmentally friendly, suitable for recycling. They do not absorb or emit foreign odors, do not contain bisphenol A (BPA free) and polyvinyl chloride (PVC free), are characterized by special strength and resistance to high temperatures. The thermos fully complies with the International Quality Standard EN12546:1-2000.
