October 2nd, 2023

When looking for an ideal vacuum flask, we need to know why and where we will be using it. For keeping coffee or tea, the best choice would be a coffee pot vacuum flask that is designed for use on many occasions. As Vietnam’s leading manufacturer of vacuum flask products, Rang Dong may have several suggestions. Here is a brief for the coffee pot vacuum flask.

Rang Dong’s high-quality vacuum flask


Rang Dong’s vacuum flask, model RD1235 N1, can be a perfect coffee pot

If we want to bring cold drink along for a picnic or party, the coffee pot is the best choice. Capable of storing 1.2 liters (40.6 U.S. fl. oz.), it is a great way for keeping coffee or any beverage. The heat retention after six hours is more than 80oC. Keeping beverages hot for 12 hours or cold for 24 hours, Rang Dong’s coffee pot help us enjoy the drink until the end of the party. The coffee pot vacuum flask also has a convenient hang so that you can bring it anywhere, just open a twist at top and pour beverage out.

For a traveler, or someone looking for a light bottle to carry along, this hand-held vacuum flask fits well as it weighs only 0.7 gram, with a slim and stylish design. However, it is able to keep our beverage hot (or cold). It is convenient to travel, and suitable for many occasions, such as shopping, traveling, playing sports, in office or at school.

The body is made from Polypropylene, capable of retaining heat, so it is safe when we touch or hold the flask. Rang Dong’s product comes in different colors such as blue, brown, green, orange and pink, giving customers a wide choice. The glass refill inside is made from silver coating that is safe for health.


The vacuum flask comes in many colors, with a modern design.

RD 1235 N1 ideal for hot drinks

Once we’ve prepared our tea or coffee and about to go out in the morning, a right pot for it will be all we need. RD 1235 N1 has a useful strainer and a perfect glass refill that locks in temperature to preserve flavor and freshness for all day. 

Additionally, a twist-off of the lid and we’ll get a cup. A push button makes it simple to pour the drink with just one hand. The flask has a large mouth opening so filling and cleaning is easy. The plastic body stays cold thanks to the excellent heat retention feature.

User’s guidance

Like any other products, the vacuum flask also needs proper maintenance and cleaning to increase its durability. Do not drop it to avoid breaks or water leakage. Since it is a hot drink in storage, we should drink slowly and do not pour it suddenly to avoid getting burns.

After cleaning, please make sure that the sealing ring is properly installed. If it is placed incorrectly or not installed, it will cause water leakage.

One of the easiest ways to clean the vacuum flask is using the cleaning brush and baking soda. It can help us clean inside, including the lid. Mix a teaspoon of soda with warm water. Let the mixture sit in the flask overnight or longer if the stains are hard.

Using baking soda will get our vacuum flask back ready.

Rang Dong’s vacuum flask affordable and multi-functional

An ideal vacuum flask can keep a little temperature change for hot or cold beverages. A hot drink stays at its optimal temperature of up to 80 degrees C after six hours in storage, while a cold drink should last up to 24 hours.

Rang Dong’s flask can conveniently keep medicinal herbs, herbs for health benefits or common drinks for various occasions such as picnics or travels. Suitable for students, office staff. Its design has its industrial copyright and patents registered, with various decoration colors and vibrant patterns that can be displayed at many places.
