Key benefits Keeps beverages hot for 10–12 hours using double insulation—ideal for serving many people without reheating. Durable, food-safe interior: inner lining is 304 precision food grade stainless steel for safe contact with water, coffee, or other hot drinks. Designed for safe, easy handling: sealed rotating temperature-lock cap prevents accidental spills and reduces heat transfer; thickened carrying handle and balanced triangular support make transport stable and secure. Large capacity options (6L, 8L, 10L, 12L, 16L, 20L) reduce refills and simplify serving at events or busy locations. Main features and how they solve problems 304 precision food grade stainless steel inner lining: resists corrosion, prevents flavor transfer, and meets food safety expectations — no metallic aftertaste and easy to maintain. Double insulation: retains heat for 10–12 hours so you can prepare hot drinks in advance and serve throughout the day without an external heat source. Note: this is passive, physical insulation only; there is no heating element. Sealed rotating temperature-lock seal: locks the lid securely to prevent spills and blocks heat escape; rotation and tightening are designed so the cap won’t burn your hands. High-temperature resistant resin tap: durable and safe for dispensing hot beverages; simple to operate and easy to replace if needed. Wide opening for easy filling and cleaning: large mouth simplifies pouring, adding ice or coffee, and allows thorough cleaning with a sponge or cloth. Balanced, ergonomic carry: thickened handle and triangular mechanism balance improve stability when lifting and moving full units. Suitable uses (practical scenarios) Office or workplace: place in a break room to serve coffee or hot water to multiple employees without frequent refilling. Events and catering: choose 12L–20L models for meetings, conferences, or buffet lines where continuous hot beverage service is needed. Home gatherings and family use: the 6L–10L sizes fit family parties, brunches, or outdoor picnics when you want convenient, long-lasting hot drinks.
