March 30th, 2024

To make vintage spaces, antique items are a must. The following article is about one of the kitchenware popular several decades ago. Rang Dong’s 2-liter vintage vacuum flask has won the love by consumers in Southeast Asian countries. The product is the prime choice for antique shores and vintage coffee shops. 

General information 

While Rang Dong has a diverse series of vacuum flasks with modern look, it still keeps one classic item, often referred to as a "vintage vacuum flask". Here are some details of the model released by the Hanoi-based company, which is Vietnam's leading manufacturer of LED and vacuum flask products: 

  • Model: RD-2035 S1 
  • Capacity: 2 liters 
  • Materials: Aluminum lid and shoulder, Steel case, Glass liner, Rubber gasket, Wood stopper

  • For keeping boiling water 
  • Rang Dong's production capacity: 24 million vacuum flasks per year and 70 million glass liners per year 

 

Rang Dong’s classic flask comes with feature patterns from the 1980s. 

Features 

Rang Dong’s vintage vacuum flask comes with only one type of volume, 2 liters, but in various patterns on the case. The patterns fit the classic style which were beloved in the 1970s and 1980s in Southeast Asian countries. They feature deep red, colorful images reflecting the nature and life of this time. Most consumers in the countryside would choose this item, and many classic coffee shops would use this vintage kitchen stuff for interior decoration. With brown, gray and white tone, pattern including several dried flowers and other old stuff, the Rang Dong flask brings a rich-in-vintage interior space to customers.​ 

It is not difficult to find this vintage flask in any market, and in medium homeware shops. In Vietnam, this vintage vacuum flask is about 60 years old. So why is it still alive? The simple reason is that it shows the unforgettable memory of a long period experienced by middle-aged and elderly Vietnamese. In the past, each family owned one classic 2.0-liter vacuum flask. Only in special events such as weddings, new-house parties or Lunar New Yea festival, people would buy this type of vacuum flasks as a precious and gorgeous present.​ 

 

Many retro flasks can be found at antique stores. 

The bottle is made of neutral glass, which has been proved to be the safest material for food contact. This bottle, or the ‘glass liner’, has 5 layers, therefore it can help the vintage vacuum flask keep hot in a relatively long time, about 8-10 hours. 

Another reason why consumers in rural areas would choose this classic flask is because of its low cheap price. Compared to modern flasks, this item is much cheaper, so low-income users could afford. 

How to use 

Just twist the lid, lift the stopper, point the flask downward, then hot water can drain out. Then place the stopper and twist the lid to close. 

Please remember not to keep gas drinks or put ice cubes into the flask. 

Avoid dropping or any hard impact on the flask to prevent the glass liner from breaking. 

It is recommended to clean the flask with warm water on a daily basis. 

Please keep it out of children's reach.
