Pure Titanium Office Vacuum Flask

1. The bottle body, inner lid and lotus‑shaped filter are made of TA1 pure titanium, with a titanium content above 99.6 %. Titanium naturally forms a dense oxide film on its surface and resists acid and alkali corrosion at room temperature. It can safely hold tea, coffee, fruit juice, milk, traditional Chinese medicine and other beverages, without any reaction, without heavy‑metal leaching, and without a metallic taste. Tested by the Guangdong Provincial Center for Microbial Analysis and Testing, the material shows an antibacterial rate of 99 % after 24 hours under photocatalytic action.

2. Titanium has a low density, making it lighter than stainless steel. The 345 ml model weighs about 0.21 kg, while the 435 ml model weighs about 0.24 kg; an empty bottle is roughly the weight of a typical smartphone, so it is easy to carry for commuting, business travel or outdoor activities. It uses a multi‑step heat‑retention process (double‑wall vacuum construction) that effectively reduces heat loss. The lid contains a heat‑resistant silicone rubber sealing ring that provides a strong seal and prevents leakage even when the bottle is inverted.

3. It abandons traditional spray‑painting technology, eliminating the risk of coating peeling and giving a unique texture that is environmentally friendly and durable. The pure‑titanium lid has a simple, refined feel; the inner lid’s water‑contact surface has been upgraded, and its grooved design prevents dripping when opened. The pure‑titanium lotus filter is paired with a silicone rubber protective ring, allowing smooth filtration without scratching the bottle wall. The smooth, rounded mouth is finely polished for a comfortable touch.
