A carefree walk in the park or around the city, commuting to work or to the institute, hiking in the mountains or road trips, working out at the fitness center or outdoors will be much more enjoyable with the GUARDIAN series thermos cup. The new model of the thermos cup in a sport-chic style combines comfort and an original appearance. Modern trends, which the company-creator of the world's first thermos is oriented towards, are reflected in the dynamic design and practical functionality of the thermos cup, designed for daily use. Regardless of the environmental conditions, in heat or cold, drinks in your thermos cup will stay hot for at least 10 hours or cold for up to 24 hours. Maintaining the desired temperature inside the thermos is ensured by the THERMOS® deep vacuum insulation technology, structural features, and premium-class materials used in its production. The body and inner flask made of food-grade 18/8 AISI 304 Stainless Steel are distinguished by their strength and thermal resistance. The steel does not react chemically with the contents, preserving the taste and aroma of the drinks. The lid-plug is made of modern food-grade plastic that is BPA-free, resistant to mechanical damage, and high temperatures. The thermos cup's seal and gasket are made of durable and hygienic food-grade silicone for airtightness. All materials are environmentally friendly, safe, and do not emit or absorb any foreign odors. The visual effect of the thermos cup's design is complemented by the pleasant tactile sensation of its coating, created using a special powder coating technology, and the ergonomic shape provides comfort when holding the thermos cup. The design dynamics continue in the usage dynamics thanks to the special construction of the lid-plug. You can drink from the thermos cup even on the go - it is easy to open with one hand, just press the button, and the top lid flips open, automatically locking in the open position and not tipping over during drinking. The smooth flow of the drink is created by the special shape of the spout and a small pouring hole, making the thermos cup ideal for hot drinks. The locking ring prevents accidental opening of the thermos and spillage of liquid. The relief band at the neck of the thermos cup adds convenience when opening it to fill it with your favorite drink. The presence of a handle with a soft elastomer overlay adds functionality to the thermos cup - it is convenient to carry in your hands or attach to a backpack. The compact size allows you to place the thermos cup in a bicycle holder or car cup holder. The modern and reliable thermos cup from the legendary THERMOS brand is an eco-friendly alternative to plastic and paper cups. In all its characteristics, the thermos cup complies with the International Quality Standard EN12546:1-2000.
