General Specifications 

The Rang Dong double-wall insulated stainless steel flask series is engineered to cater to a wide range of users, with flask capacity ranging from 0.36 liters to 1 liter.  

High-quality 201 and 304 stainless steel types are used for each model to ensure both durability and superior heat retention. The double-wall insulation technology traps heat between the layers, maintaining the temperature of beverages for up to 12 hours for hot drinks and 24 hours for cold ones. 

Each flask in the series is equipped with a tightly sealed lid to prevent spills. The lids are made from either 304 stainless steel or high-grade polypropylene (PP) plastic, with certain models featuring innovative extras such as temperature displays and removable stainless steel tea strainers.  

Silicone gaskets are included across all models to resist leakage, making these flasks reliable and safe for travel. 

Rang Dong's flasks come in a variety of colors and patterns, allowing for personalized style while maintaining functionality. 

Models RD-BGN04ST1 and RD-BGN045ST1 are available in various color and pattern options, allowing customization to match user's personal style. The attention to detail in the construction, combined with these custom design options, makes each flask both practical and aesthetically pleasing. 

Exceptional Features 

Rang Dong’s double-wall insulated stainless steel flask series boasts several exceptional features that distinguish it from other products on the market.  

The use of a double-wall structure not only enhances heat retention, but also ensures that the exterior of the flask remains comfortable to the touch, regardless of the temperature inside. The 201 and 304 stainless steel combination provides robust protection against corrosion and long-lasting performance. 

The removable stainless steel tea strainer allows for convenient brewing of loose-leaf teas directly in the flask. 

Each model is designed with user convenience in mind. For example, the RD-BGN05ST1.E includes a digital temperature display, allowing users to check the temperature of their beverage at a glance.  

Model RD-BGN05ST2 with a silicone rubber outer coating provides a secure grip and additional resistance to wear and tear. Meanwhile, models RD-BGN036ST1 and RD-BGN05ST1 incorporate removable stainless steel tea strainers, offering users the flexibility to brew their favorite loose-leaf teas directly in the flask. 

Other thoughtful features include the use of a twist-open lid that can also serve as a drinking cup, as seen in models like the RD-BGN05ST3.E. Select models, such as the RD-BGN045ST1.E, also feature spill-free drinking straws made from food-grade silicone, perfect for convenient, on-the-go hydration. 

Applications 

For busy professionals, these flasks provide a reliable solution for keeping coffee hot during long commutes or maintaining the perfect temperature for tea throughout a working day. The compact sizes of models like the RD-BGN036ST1 and RD-BGN045ST2 make them easy to carry in a bag or backpack, making them ideal for daily use or travel. 

Flasks make an ideal choice for yoga athletes, keeping their drinks at the perfect temperature during or after practice. 

For outdoor enthusiasts, the RD-BGN10ST1 offers a larger 1-liter capacity, perfect for hiking, camping, or extended trips where hydration is essential. Its durable stainless-steel construction and robust heat retention capabilities keep beverages refreshing, whether hot or cold, for hours.
