Elegant Big Size Vacuum Flask

The Elegant Big Size Vacuum Flask is a 1-liter thermal container designed for daily use, featuring a double-walled vacuum-insulated glass liner manufactured using Japanese technology to maintain liquid temperature for extended periods. The outer body, lid, stopper, and base are all constructed from polypropylene (PP) plastic, selected for its chemical resistance and impact durability. The flask includes a detachable lid that doubles as a drinking cup, enhancing portability and convenience.

The glass inner liner is borosilicate-grade, with a vacuum seal between the two walls to minimize heat transfer. The outer PP casing is molded with skid-resistant texturing on the base and includes a built-in carrying handle. The stopper is designed for single-handed operation and seals with a silicone gasket to prevent leakage. Color and pattern options are customizable, and OEM branding is accepted, allowing logos to be printed on the body or lid.

This flask is primarily purchased by distributors in food service, healthcare, and outdoor retail sectors for bulk resale. Orders are typically placed in quantities of 500 to 5,000 units, packed in cartons of 20 or 50. Packaging is designed for stacking and transport efficiency. Lead times vary based on customization, and shipping is available under FOB Haiphong or EXW Hanoi terms. No certifications are listed, so buyers must verify compliance independently.
