Superior Thermal Retention Technology

Our double-wall vacuum insulation keeps beverages hot for up to 12 hours and cold for 24 hours, ensuring your coffee stays at the perfect temperature throughout the day.

This technology is backed by our ISO-certified manufacturing process, which guarantees consistent quality across all units. We use 304 stainless steel, known for its durability and resistance to corrosion. The thermos also features a non-slip base and ergonomic handle for comfortable carrying. For businesses, this means a product that exceeds customer expectations, reducing returns and enhancing brand loyalty. Our engineers can adjust insulation layers to meet specific temperature retention needs, offering a competitive edge in the market.

Frequently Questions

How does the leakproof feature work?

Our leakproof coffee thermos uses a specially designed silicone gasket and threading mechanism that creates an airtight seal. This prevents any liquid from leaking out, even when the thermos is shaken or placed upside down. The gasket is made of food-grade silicone that remains flexible and durable, ensuring a reliable seal over time. We rigorously test each unit under extreme conditions to guarantee 100% leakproof performance.

What is the temperature retention capability?

Our thermos uses double-wall vacuum insulation, which keeps beverages hot for up to 12 hours and cold for 24 hours. The copper-coated interior enhances thermal reflection, maintaining the desired temperature. Actual duration may vary based on ambient temperature and frequency of opening. This performance makes our thermos ideal for long commutes, outdoor activities, and office use.
