Premium stainless steel vacuum flasks for long-lasting thermal insulation in travel & daily use

Stainless Steel Vacuum Flasks are insulated drinking products crafted from stainless steel with a vacuum insulation structure. They are suitable for various scenarios including office, commute, travel and outdoor activities. In the design of this product series, Jianyang places greater emphasis on structural stability and reliable performance for daily use, facilitating long-term repeated utilization.

Double-Wall Vacuum Structure Reduces Heat Loss

The product adopts a double-wall stainless steel vacuum structure, which effectively minimizes heat exchange between the inside and outside. Hot beverages can maintain temperature for an extended period, while cold drinks are less prone to warming up due to external conditions. This structure delivers stable performance during movement, making it ideal for carrying around.

Food-Grade Stainless Steel Inner Liner

The inner liner is made of food-grade stainless steel, featuring corrosion resistance and rust resistance, which can reduce odor retention. Whether it is water, tea or coffee, the original taste can be preserved. It is also relatively easy to clean, making it suitable for high-frequency use.

Secure Sealing to Prevent Leakage

The bottle cap and mouth adopt a screw-on sealing design, combined with a sealing ring structure, to lower the risk of leakage. When placed in a backpack or car, it can reduce liquid spillage caused by tipping, enhancing safety in use.

Multi-Specification Design for Easy Portability

Stainless Steel Vacuum Flasks are available in a variety of capacities to meet different drinking needs. The overall shape prioritizes practicality, easy to hold with one hand and store in daily life. In terms of functional positioning, it complements products such as Travel Mugs and Stainless Steel Water Bottles, allowing users to choose according to usage scenarios.

Suitable for Multi-Channel Sales

This product series features mature structure and clear application scenarios, making it suitable for e-commerce platforms, wholesale channels and customized projects. Jianyang attaches importance to consistency and controllability in the production process, facilitating large-scale supply and classified display.
