Key benefits Long-lasting heat retention: vacuum-insulated design keeps beverages hot for up to 48 hours, so you don’t need an external heater or frequent reheating. Safe and durable construction: thickened PP outer layer, PU foam insulation and a stainless-steel inner lining combine to resist pressure, preserve temperature and provide a safe drinking container. Leak-proof for travel: a strong locking mechanism creates a reliable seal to prevent spills and overflow during transport. Low-maintenance: wide mouth opening makes filling, pouring and quick cleaning simple — a quick wipe is usually all that’s needed. What this solves Eliminates the need to constantly reheat coffee or tea during long days or trips. Reduces the risk of accidental spills while commuting, in a bag or on a vehicle. Simplifies daily use and care with an easy-to-refill, easy-to-clean design. Features and performance Materials: thickened polypropylene (outer shell) + PU foam insulation + stainless-steel lining (interior). Insulation: vacuum insulation enables extended heat preservation without active heating. Seal: robust locking mechanism for leak resistance. Access: large mouth opening for easy filling, pouring and cleaning. Practical uses Commuting and travel: carry hot coffee or tea securely in a bag or vehicle without worrying about leaks or frequent reheating. Outdoor activities: keep beverages hot during day trips, picnics or light camping where access to reheating is limited. Office and meetings: bring a reliably hot drink to long workdays or extended meetings without relying on office appliances. Care and handling Rinse or wipe the interior after each use; the large mouth opening speeds cleaning and refilling. Secure the locking mechanism before transport to ensure a leak-proof seal. Designed for safe, pressure-resistant use thanks to its layered construction (PP outer layer, PU foam, stainless-steel lining). This product combines reliable thermal performance, secure transportability and simple maintenance to keep your hot beverages ready when you need them.
