Built with high-quality materials and a premium glass liner, the device delivers reliability and elegance. The following article explores the specifications, exceptional features and diverse applications of this well-crafted product. 

The color options for model RD-2035N8 are inspired by Pantone tones to create a stylish touch 

General Specifications 

Model RD-2035N8 is crafted to deliver dependable performance with a touch of classic elegance. Capable of storing 2 liters of liquid, it can cater to family gatherings, office groups or traveling, where constant and prolonged access to drinks is required. The flask’s exterior components, including the body, the lid and the bottom, are made from virgin polypropylene (PP), a food-safe plastic that offers strength and thermal insulation while remaining lightweight and BPA-free.    

At the heart of the 2-liter classic style vacuum flask is a premium glass liner, which provides excellent heat retention and preserves the natural flavor and aroma of the stored liquid without absorbing odors or stains. 

A silicone gasket enhances the flask’s airtight sealing, strengthening the ability to keep liquids hot for up to 12 hours and cold for up to 24 hours. 

These specifications make the flask a practical solution not only for daily hydration, but also for events and journeys where access to temperature-controlled drinks is essential.  

Exceptional Features 

Beyond its capacity and material quality, this 2-liter classic style vacuum flask distinguishes itself  by well-considered design features.  

The outer body is adorned with reflective heat-transfer floral printing, blending functionality with a decorative element that adds charm to any kitchen, desk, or outdoor setup.  

The flask’s aesthetic appeal enhances its role as both a utility item and a stylish accessory in hospitality or personal settings. 

Model RD-2035N8 includes a safe cap, a glass liner, a tight seal and a smooth-flow spout. 

A defining feature of this 2-liter classic style vacuum flask is the dual-lid mechanism. The outer lid is multifunctional as it can be used conveniently as a drinking cup while  on the go. 

The inner lid is engineered with a precise flip-lock system. A small lever on the lid operates in two simple steps: flip it up to allow water to pour out, and flip it down to seal the lid, effectively preventing spills or leaks.  

This user-centric mechanism provides fast access to hot or cold beverages without compromising insulation or safety. 

Elegant and portable, Rang Dong's RD-2035N8 vacuum flask is decorated with a floral print, perfect for home or travel. 

The flask’s spout design contributes significantly to user satisfaction. It directs water in a clean, consistent stream while minimizing mess during pouring. Whether refilling cups at a family gathering or serving drinks in a shared workspace, the directed flow helps avoid drips and splashes.  

The ergonomic side handle offers a steady grip, particularly useful when the flask is full. Complementing this is a non-slip top handle—also made of sturdy plastic—which supports easy carrying between rooms or for outdoor events.  

Applications 

The 2-liter classic style vacuum flask is versatile and well-suited to a wide range of everyday and specialized applications.  

In residential settings, it functions as a reliable household item for keeping tea, coffee or herbal infusions warm through extended mornings or evenings. Its generous capacity reduces the need for frequent refills, making it ideal for family use or small gatherings. 

RD-2035N8 vacuum flask fits seamlessly into both cozy home settings and modern office spaces. 

In professional and shared spaces, such as meeting rooms or workstations, the flask provides a practical solution for serving beverages without relying on electric kettles or refrigerators.  

The controlled pouring and hygienic lid structure make it a suitable choice for settings where cleanliness and convenience are essential. 

Outdoors, the flask excels in functionality. Whether on road trips, camping weekends or open-air events, its strong thermal insulation and robust build help maintain beverage quality throughout the day.  

Thanks to the non-slip handle and the sealed design, the flask is a trusted companion in unpredictable weather or rougher terrain. It is also useful in mobile stalls, market booths or fieldwork environments where stable temperature maintenance and mobility are key considerations.
