A medium 1-liter flask bottle makes perfect personal choice

As the world has now entered the third year of fighting the COVID-19 pandemic, people tend to keep distance while going out to prevent infections. Using a 1-liter flask bottle, which is more convenient while traveling while the item can be personalized, has become more common as it also helps consumers keep hygiene.

Personal choice

The pandemic has hit the world economy and changed the entire social and business life. Traditional businesses have transformed into digital operations, switching to online transactions. People's daily life habits have also been changed, as more tend to keep distance to avoid infections. Now many prefer drinking from their own bottle, instead of sharing with others.

As keeping hygiene has become more important than ever, the 1-liter flask bottle can play an active role in helping people ensure their safety.

Given the 1-liter capacity, the size of the flask bottle makes it convenient to hold and bring along while we go out.

Its volume is suitable in meeting around half the daily requirement of water drinking per person.

Besides, manufacturers have become flexible in making possible for the bottle to be customized according to user's taste. These factors have all added up to make the flask bottle a favorite item.

Things to consider when choosing a personal flask bottle

In order to select a safe flask bottle, we should carefully consider the following criteria.

Bottle material

Neutral glass and high-quality stainless steel are safe materials for food containers and bottles used to keep either hot and cold drinks. When it comes to plastic, only very good plastic is safe, so consumers need to consider the plastic material carefully before picking a plastic bottle. If manufacturer's guidance shows the plastic bottle can withstand a temperature of up to 140 degree Celsius, we can buy it.

Borosilicate glass is used by Rang Dong, Vietnam's leading manufacturer of vacuum flask products, to make 1-liter flask bottles.

Material of the bottle's other parts

While other parts of a flask bottle do not come in direct contact with food and drink, they may still affect overall hygiene. As they are designed for heat insulation, decoration, easy holding, and even to prevent electric shocks, we should also choose a bottle with safe parts. For example, ABS and PP plastic are good materials as they are fire-proof, heat and electricity insulated.

Reliable brand and warranty

Reliable brand is an insurance for product quality and warranty service. A famous firm always provides a good after-sale service for customers. Making quality products is a sure way for them to protect their brand prestige.


A careful study of the bottle's specifications is needed before our purchase. The temperature should range from minus 10 degrees Celsius to over plus 120 degrees Celsius, a range considered good for keeping hot drinks without releasing any toxic chemicals. If there is a caution to avoid keeping gas drinks or beverage with high acid content, a purchase is not recommended.

Tips for keeping good hygiene of the flask bottle

A flask bottle from safe materials may not be safe enough for our health. A lack of proper cleaning could lead users to suffer from infected diseases. A daily cleaning is highly recommended to keep good hygiene. Please use a small and long brush to clean the bottle's inside, while the outer part can be wiped with a cloth after a long-day use.

Leftover drink should be disposed properly everyday. If we detect any abnormal smell, taste or color in our drink, changing the bottle should be done immediately.
