There has been a shift in the consumers’ mindset to be environmentally more responsible and health-conscious. One of these has been the use of a vacuum flask instead of a plastic bottle. A vacuum bottle has many advantages over plastic ones. Fluids are more comfortable to store in vacuum flasks while retaining the temperature of the stored liquids. You can save not only water and chilled drinks but also soups and other hot beverages that you can’t store anywhere else. These factors make a vacuum bottle a great alternative to regular containers.

A thermos bottle is an excellent choice for you to make homemade beverages like tea or coffee before you head out. You won’t end up spending money on coffee or tea outside.

There are a few things you need to know about vacuum flasks like maintenance, types, and usage before you decide to buy one for your personal use. Here are the five things you need to know before buying a vacuum flask.

The Purpose

A vacuum flask is a multipurpose bottle, but often, many use it for wrong reasons. When you consume beverages like tea or coffee or drinks like lime juice or iced tea at room temperature, they do not taste good. With a thermos bottle, it is easy to store either hot beverages or cold drinks. If you want to carry water at room temperature, you can go with a normal bottle, but for hot or cold liquids, a vacuum bottle is your best bet.

Material

The material of the thermos will have a significant impact on the heat retention capability of the bottle. The flask will also determine the durability of the vacuum flask. There are many options available today. Plastic and stainless Steel are the most popular options. Going for a plastic vacuum bottle will reduce the cost of the bottle but it’s not that good. Vinyl doesn’t retain heat as good as other materials. It is also prone to breakage. Stainless steel (or any metal) flasks are recommended as they are durable. They also retain heat for a long time and are easier to clean. Stainless steel is better than other metal options as it doesn’t rust, and the shiny look of the bottle is eye-pleasing.

Lid

As the saying goes – ‘The chain is only as strong as its weakest link’, the lid is the weak link for a thermos bottle. If the container is made with utmost care to insulate heat but the lid is not airtight, the bottle is not a good thermos.The thermos’ lid should be sealed and effective for a flask to retain heat to a maximum. The top shouldn’t leak or come off quickly. It should also be easy to clean. Most of the vacuum flasks come with a screw lid, which is much more effective than a cork-type lid. It would be best if you also keep in mind that the lid should be made up of the same material as the bottle. In a nutshell, the lid should be leak-proof and airtight.

Warranty

At the end of the day, a vacuum flask is made in a factory and is susceptible to defects. As a thermos bottle will cost significantly more than a regular bottle, a warranty is a must. Some manufacturers will give warranties that last years while some don’t offer a warranty at all. It is always advised to buy flasks with a warranty to be sure that you are covered if any problem occurs.

Capacity

The capacity of the bottle is an essential thing for you to select a bottle. It depends on your usage and how often you use the vacuum bottle. Vacuum flasks have a capacity range from 500 ml to 1000 ml. If you are purchasing a flask for long treks, you should go for a higher capacity flask. If you are looking to use it for coffee or tea for the day, a 500 ml flask would be enough.

In addition to these five things, you should also consider the cost, brand, and online reviews before you purchase a thermos bottle. This can help you buy the right vacuum flask for your requirements.
