Thermal bottles: the right choice for the environment and for health

When we talk about thermal bottles we refer to containers for drinks designed to maintain the temperature of the drinks for an extended period of time.

These water bottles are usually made of stainless steel or insulating materials such as the vacuum between the walls, which reduces the loss of heat or cold. Thanks to this feature, thermal bottles are able to keep drinks hot or cold for several hours, depending on the model and quality of the bottle.

Thermal bottles are often used to contain drinks such as coffee, tea, milk, fruit juice or water, so that they can be consumed at the ideal temperature during daily activities or during outdoor excursions.

What are the characteristics of a thermal bottle?

The characteristics of a thermal bottle may vary depending on the model and manufacturer, but in general, thermal bottles have the following characteristics:

Thermal insulation: Thermal bottles are designed with insulating materials, such as vacuum between the walls or special foams, to maintain the temperature of the drinks for an extended period of time. This allows you to keep drinks hot or cold as needed.

Capacity: Thermal bottles come in different capacities, from the smallest ones, usually around 350-500 ml, up to the largest ones, around 1.5-2 litres.

Material: Thermal bottles are made of various materials, including stainless steel, aluminum, plastic or glass. Stainless steel is the most common material because it is strong, durable, and easy to clean.

Lid: Most thermos bottles have an airtight lid that prevents drinks from leaking and maintains thermal insulation. The lid can be screw or pressure.

Design: Thermal bottles are available in different colours, shapes and designs. Some thermos bottles also have handles, carrying straps or buttons for the spout.

Ease of cleaning: Thermal bottles must be cleaned regularly to maintain the quality of the material and the thermal insulation. Most thermos bottles are easy to clean and can be washed by hand or in the dishwasher.

What are the best occasions for using thermal bottles?

Thermal bottles are very versatile and can be used on numerous occasions. Here are some examples:

Sports activities: thermal bottles are perfect for athletes who want to stay hydrated during physical activity, whether it's a run, a walk, a yoga session or any other sporting activity.

Travel: A thermos bottle is an ideal companion for travel, whether it's a short trip out of town or a longer journey. You'll be able to keep your favorite drink hot or cold while traveling without having to spend money on bottled drinks.

Work and study: If you work or study in an environment where access to fresh water or drinks isn't available, an insulated bottle can be a practical solution to keep you hydrated.

Outdoor Activities: If you enjoy spending time outdoors, such as camping, hiking or at the beach, a thermos bottle can be a great way to keep your favorite drink cool or warm.

Home: Thermal flasks can also be used at home, for example to keep your tea or coffee hot while you watch TV or read a book.

It can be deduced that thermal bottles can be used at any time when you want to maintain the temperature of a drink, without having to resort to plastic bottles or other less ecological solutions.

Here's how to best choose the thermal bottle for sports and study... some information to keep in mind:

What is the capacity of a good thermal bottle?

The capacity of a thermal bottle depends on your needs. If you usually carry a lot of water with you during the day, then it might be better to choose a thermal bottle with a larger capacity, such as 1.5 or 2 liters. If, on the other hand, you prefer to carry a lighter and more manageable bottle, a capacity of 500 ml or 750 ml could be sufficient.

What is the best material for a thermal bottle?

Thermal bottles are available in various materials, including stainless steel, aluminum, plastic or glass. Stainless steel is the most common material because it is strong, durable, and easy to clean.

How long can a thermal bottle keep a drink hot or cold?

The temperature retention time depends on the quality of the thermal bottle, the initial temperature of the drink and the environmental conditions. Generally, a good thermal bottle can keep a drink hot or cold for at least 6-8 hours.

How do you clean a thermal bottle?

Most thermos bottles are easy to clean and can be washed by hand or in the dishwasher. However, some models require special care to maintain the quality of the material and the thermal insulation. We recommend following the manufacturer's instructions for proper and safe cleaning.

Can you put the thermal bottle in the microwave?

No, most thermos bottles are not suitable for use in the microwave. Furthermore, it is not advisable to put hot drinks in the thermal flask that has just been removed from the freezer, as it could cause damage to the material or the hermetic seal.
