The 500ml double-walled vacuum insulated thermos bottle is built for reliable daily performance and long-term supply programs. Designed with a classic bullet-style profile and press-button stopper system, it remains one of the most stable and consistently demanded models in the insulated drinkware category.

The inner liner is made of 304 stainless steel, ensuring safe contact with beverages and resistance to corrosion. The vacuum insulation structure helps maintain temperature for approximately 8–12 hours, depending on usage conditions. This performance range makes it suitable for office use, commuting, travel, and outdoor environments where temperature retention is required but extreme insulation duration is not necessary.

The bottle is equipped with a press-type inner stopper, allowing controlled pouring without fully removing the lid. This design minimizes heat loss during use while improving convenience. The outer screw cap functions as a drinking cup, providing additional practicality for business trips, outdoor activities, and corporate gifting scenarios.

The 500ml capacity is widely accepted across global markets. It offers sufficient volume for daily hydration while maintaining portability. Its cylindrical structure allows efficient packing in cartons, making it suitable for wholesale distribution and promotional supply programs.

From a sourcing perspective, this model offers balanced insulation performance, structural durability, and cost control. The double-wall construction reduces external condensation and improves user comfort when holding hot beverages.

The exterior surface can be customized with various finishes, including color coating and textured treatments. Logo application methods include laser engraving and silk screen printing. Custom packaging solutions are available to support private label programs and promotional campaigns.

For markets requiring compliance documentation, food-grade certification can be provided upon request. The use of 304 stainless steel for the interior liner supports regulatory requirements in regions with stricter standards.

This thermos bottle is suitable for wholesalers, distributors, promotional gift suppliers, and brands looking for a reliable stainless steel insulated bottle with customization flexibility and stable supply capacity.
