Which thermos is better to choose for tea - expert advice

What are thermoses?

When choosing a thermos, you should start with the purpose for which you are buying this household utensil. Depending on their purpose, thermoses are:

• for drinks - in this case, the options are presented in the form of a tall vessel with a narrow neck or in the form of a mug; the first option is more practical for traveling and long trips;
• for food it is a cylinder, but lower than a standard thermos. There are also options in the form of boxes, mini-pots, and tanks.

When choosing a thermos, be sure to think about what exactly you plan to transport in it, since the volume of the dish and its purpose depend on this.

Types of thermoses

The design of any device of this type has a flask with double walls. The shape varies depending on the purpose of the dish. Most of the options are similar, but there are still variations. There are thermoses for tea, coffee, and separate models for food: soups or cereals. There are options made of plastic or a combination of these materials; steel models are considered more reliable.

Universal models

The correct universal model has a wide neck and a universal-type lid. To get food you need to unscrew the lid, for a drink you just need to open the cap. This option is often presented in excellent volume and also maintains the temperature for a long time. There are lids made of glass or metal.

Bullet

Cylindrical shape that resembles a bullet. Advantages: compact size, ideal for carrying in a bag or backpack. Many companies that produce travel accessories specialize in the production of this type of thermos.

Pneumatic pump

A wide vessel, which is equipped with a large lid with a pump, is an element whose hose reaches to the very bottom. A distinctive feature of this device is that you do not need to remove the lid to pour the drink. If you want to choose a practical, yet roomy thermos, pay attention to this option. It retains heat for a long time and is easy to use.

Sudkovy

In this case, there are no models with a wide neck, since this is a design that can accommodate up to 3 plastic containers. This option is optimal if you need to store a multi-course meal in one place.

Thermal mugs and thermal bottles

The optimal solution for sports fans or frequent travelers, since you can drink on the go, just press the button located on the body.

Types of thermoses

To know which tea thermos is best to choose, you need to understand how to choose this item. You will need to familiarize yourself with the basic characteristics of household cookware (material, volume, additional functions), and also take a closer look at the manufacturer.

When choosing, you will need to familiarize yourself with the main characteristics of household cookware, as well as take a closer look at the manufacturer.

From various materials

The thermos body is made from two types of materials: plastic and stainless steel. The plastic case is lighter in weight and is convenient to carry, but plastic gives off heat faster and also cracks at the slightest mechanical damage. A plastic tea thermos will be convenient to take with you on a walk, study or work, but this material is not suitable for long hikes, hunting or fishing.

The metal body retains the temperature of the drink longer compared to plastic counterparts. The case is made from a special alloy that is not afraid of corrosion, mechanical damage or shock.

The special flask, which is located inside the thermos, is made of glass, plastic or metal.

1. Metal. A metal flask quickly loses heat, but is very durable. Such a flask will not break if the thermos suddenly falls.

2. Glass. A glass flask perfectly retains the initial temperature of the liquid, but is fragile. The material is chemically inert, which means it will not react with the components of the liquid; tea or other drink will not acquire any foreign taste or odor.

3. Plastic. A plastic vessel retains heat for a long time, but is not absolutely safe for human health. When such a vessel is filled with high-temperature liquid, the plastic begins to release polymer substances that have a detrimental effect on our body. It is also not recommended to store drinks or food in plastic containers for a long time.

A flask with mirror glass retains heat almost 3 times longer than its counterparts, due to the fact that such material has less thermal radiation.

By volume and shape

The volume and shape of the thermos depend on your requirements and the situations in which you intend to use this item. So, for long hikes, fishing and hunting, family walks, a product with a volume of at least 1 liter is suitable. If you want to take a hot drink to work, then a container with a capacity of up to 500 ml will be sufficient.

The thermos is most often shaped like a regular cylinder. But children's thermoses can have an unusual shape and bright design.

By functions and capabilities

The functionality of the product also depends on the type of cover. Approximately 1/3 of the heat of the drink escapes through the lid of the item, so you should definitely take this into account when choosing.

1. Plastic cover. It has a high tightness, allowing the drink not to spill even if the dishes fall.

   
   The plastic lid is highly airtight and prevents the drink from spilling even if the glassware falls.

2. Plug lid. This cork is made of wood. It wears out quickly, and over time the fluid begins to leak. In modern thermoses, a plug cap is rarely used.

How to choose the right quality thermos

Which thermos to choose - stainless steel or plastic, what volume, what are the features of a particular model and other questions arise in the process of choosing this kitchen device. Next, we will look at the key criteria that you should pay attention to when choosing a product.

By volume

To choose a quality thermos, you first need to decide how much volume you need. The smallest option is 250 ml; there are models with a volume of up to 40 liters.

• 200 ml to 1 liter are small models;
• 1–2 liters - universal, standard options;
• from 3 liters - these are large-capacity.

About 1 liter can be used for 1-2 people. If you are planning a hike with your family or company, then it is better to buy models from 2 liters.

According to the materials of the flask and body

Most often, stainless steel and plastic are used for the body. But metal is better, it is stronger and more durable, and also more resistant to external influences. Plastic is the best option for a food thermos that you plan to take to work. In this case, the likelihood of external influence on the container is reduced.

Flask material:

• plastic is rarely used, advantages are affordable price and light weight, disadvantages are low heat conductivity;
• glass - easy to clean and hygienic, the bulb is replaced if a crack appears;
• steel is the optimal solution for those who buy a container for an active lifestyle.

Ability to retain heat

There are no standards regarding this indicator, so heat retention data varies depending on the manufacturer and model. According to user reviews, among domestic manufacturers, the best products are those from the Arctic company.

Please note that the heat retention rate is influenced by what technologies are used by the manufacturer, as well as the quality of the materials used. The duration of temperature retention is affected by:

• neck diameter, the narrower the better;
• type of cover, options with a button are inferior to models with threads;
• The material of the flask, when the lid is closed, glass keeps heat for up to 12 hours, metal - about 6-8 hours.

For odor insulation

The company’s description does not indicate this point, but it is very important for the comfortable operation of the kitchen device. Here you need to understand that steel models are able to absorb and retain odors. So it is better not to store milk and other dairy products, sour juices and drinks with a very strong aroma. Glass options are considered the optimal solution for isolating odors, since such models do not absorb aromas at all, but the key disadvantage is the fragility of the flask.

By shape and design

The shape depends on the purpose of the dish. Mugs or higher models are more intended for drinks, deep, cylindrical, but low options are for transporting food. Regarding design: here manufacturers offer different colors and shapes. There are options with handles, which increases comfort during operation. There are rubberized inserts that reduce slipping; such models are easier to hold in your hand.

Cork

Since the lid determines how much heat will be lost, special attention must be paid to this detail.

1. The lid is the most popular method and is used in conjunction with an additional stopper. In models with an additional stopper, the lid is an alternative to a cup.
2. Pump plugs often include a special valve for supplying fluid and an air pump. They are large in size, but retain heat for a long time.
3. Plugs with a valve are considered more practical to use. And to pour a drink, you don’t need to unscrew the lid. When you press the button, tea or coffee comes out, thereby reducing heat loss.
4. A cork with a tongue is used by manufacturers in sports versions and thermal mugs.

Which thermos should you choose - glass or metal? It all depends on the purpose of the vessel, the goals set for it and personal preferences.

Additional functions

In this case, we are talking about more modern, advanced models, in which there is a special sieve on the flask for brewing, or there is a valve for releasing steam, which is often found in options for first and second courses. You will have to pay extra for additional features; accordingly, the price of such goods increases.

What kind of thermos lid should there be?

The thermos lid is very important, so you should pay special attention to it. It must have some play and be hermetically sealed. Well-known manufacturers indicate on the labeling of their products the guaranteed heat retention time and temperature. A good indicator is the temperature of the liquid from 70 to 90°C. There are models in which a valve is provided on the inner lid; by simply pressing a button, you can pour tea into a glass without opening the thermos itself, without releasing the heat. More often there are models with a screw-on inner lid and an outer mug lid.

What you shouldn't buy

1. Products from unknown brands. There is a risk that the company uses low-quality materials or violates production technology, thereby increasing the danger to your health.
2. When there is a strong odor from the product or after removing the lid.

Be sure to read user reviews regarding this or that option. Users always point out the pros and cons of kitchen devices, this will allow them to get an objective assessment.

Basic parameters for choosing a thermos

The design of the thermos is simple. It consists of two main parts: an outer body and an inner vessel. Modern products abound with various improvements in the form of stoppers, handles, cups, pumps, etc. The classic version is a thermos, consisting of an outer body, an inner vessel, a stopper and a lid that acts as a glass. The inner container is a type of Dewar flask with two walls. The gap between the walls is sealed and the air is pumped out of it.

First you need to clearly understand why you are purchasing a thermos. Most often it is intended to be used in the following cases.

• For use in stationary conditions: in the kitchen, at home or in the garden.
• To create comfort in field conditions: on a hike, on an excursion or on a picnic.

Depending on the intended use, choose a thermos. A wide-neck model with sufficient volume and a reliable stopper is perfect for home use. For use in hiking conditions, light weight and small volume are usually chosen.

To check the serviceability of the thermos, you need to pour hot water into it and close the cap. Check for leaks immediately. If the product does not leak, and the water in it has not cooled down after 2 hours, then the product is functioning normally.

Product volume

The main characteristic of a thermos is the volume of the vessel. There are small models that allow you to maintain the temperature of the product in the size of one glass (0.25 liters). Industrial versions can be filled with up to 40-50 liters of liquid. Such products are already called thermal containers. Conventionally, there are three main categories of thermoses based on this criterion.

• Small volume. This category includes models with a volume of 0.25 to 1 liter.
• Standard option. This includes products with an internal vessel volume of 1 to 3 liters.
• Large volume. This includes models with an internal volume exceeding 3 liters.

Thermos body

Previously, thermos bodies were made only of thin metal. For this purpose, stainless steel or tin was used. With the advent of sufficiently durable plastics, the body began to be made of plastic. Today, plastic cases, especially standard and large volume ones, are not inferior to metal ones. The choice of body material depends on the desire and taste of the buyer. At the same time, you do not need to worry about the integrity of the thermos during transportation.

Flask

To make the most important part of the structure, three types of material are used.

• Glass. This traditional material was used in the very first thermos designs. But glass is not very durable. Everyone knows that cracks in a thermos flask always appear unexpectedly. In this case, it goes on the shelf until a new flask is purchased. But the thermal insulation and environmental properties of glass could not be surpassed by any material. Therefore, glass is still widely used in the manufacture of flasks.
• Metal. Metal flasks appeared later than glass ones. Their advantage is strength and durability. Metal retains temperature well, but somewhat worse than glass. Caring for the inner surface of steel flasks causes certain difficulties. Food residues stick firmly to the metal and are difficult to get rid of.
• Plastic. Recently, flasks began to be made of plastic. Durable and lightweight, resistant to shock loads. But plastic absorbs odors perfectly, and the thermal conductivity of plastics is still inferior to glass. But the development of new technologies will undoubtedly soon bring plastic to first place among the materials used for the manufacture of flasks.

You can simply check the integrity of the flask. Just shake the product well and a rattling sound will indicate a malfunction.

How to use and care for a tea thermos

The service life depends on the correct use of the thermos. Rules for caring for the device if you plan to pour tea, coffee and other drinks:

• timely washing;
• ventilation;
• thorough cleaning so that no tea leaves or coffee grounds remain inside.

Also make sure that the dishes do not fall on the floor and there are no strong impacts. Check the instructions to see if they are dishwasher safe. Carbonated drinks should not be poured into metal containers, as they accelerate the destruction of the material.

Types of thermoses

There are several types of thermoses suitable for certain tasks:

• Classic
  . The device is a bottle-type reservoir made of plastic or metal. This is the most popular type of thermos, convenient for hiking, making tea at work or in an educational institution. The volume of such tanks can range from 0.3 to 3 liters.

• Thermal mug
  . Compact tanks allow you to take a small amount (300 - 500 ml) of drink for one person. Unlike other types, you can drink from a thermal mug without pouring the contents into other containers. Please note that such a cup cannot hold the temperature for a long time, like a classic thermos, since the walls are made of single, not double (in order to reduce weight). If you like to drink tea not for breakfast, but on the way to work, then a thermal mug is your option.

• Food thermos
  . Visually similar to the classic model, but wider and lower in height. A food thermos is convenient for taking hot lunches with you to work or on a hike. Some advanced models, for example, Vinzer 89148 1.6 l Price from RUB 1,020, have removable food containers (cups with lids) and cutlery so that several people can dine at the same time (or one person, but different dishes).

• Thermos for children
  . These are the same classic models, only they have a smaller volume and a beautiful “childish” design, in the form of cartoon characters, animals, etc. Some of them have ties and carabiners so you can hang them on your briefcase. Such thermoses usually last from 2 to 6 hours. Some may include a mug, while others come with narrow dispensers for drinking directly from the bottle. It would be an ideal option for a little one going to school.

• Car mugs
  . Their main advantage is the ability to connect to a car cigarette lighter for heating (bringing to a boil will not work). The lower part is specially narrowed so that the mug stands stable in the “bar” of the car. Having brewed coffee in the morning, you can enjoy a hot drink throughout your car ride. And although such devices are mainly intended for drivers, they can be used by office workers, since the drink can also be heated from USB.

What should you pay attention to when choosing a thermos?

When choosing the right model for yourself, pay attention to the following parameters:

• Volume
  . You should choose a tank based on your needs and type of activity. If you like to often drink a little tea at work, then you will need a thermos of 1 - 1.5 liters. A model with a volume of 0.3 - 0.5 liters is suitable for a child at school. For a family of 4 adults, it is best to take a thermos jug with a capacity of 2 liters or more.
• Case material
  . Relatively inexpensive and simple models are made of plastic. Its main advantage is its light weight and variety of colors. However, it is quite fragile and in most cases fails if dropped. It makes sense to buy a thermos made of plastic for children (since it is lightweight) or in the form of a thermal mug. The best option is a metal case, as it can withstand shocks and falls well, so it will be indispensable in hiking conditions. However, it retains heat less well than plastic (depending on the manufacturer).
• Flask material
  . The time that the thermos will keep the contents hot largely depends on the flask. Glass flasks with a mirrored wall hold best. However, they are quite fragile and break immediately when dropped. Therefore, it’s worth buying a device with such a flask if you plan to use it at home and not take it on the road. For hiking and frequent trips, it is best to buy a thermos with a metal flask. It does not break, and the time it takes to keep the drink hot can reach 36 hours, depending on the manufacturer. Plastic flasks are mainly used in inexpensive models. Their advantage is lightness and long-term heat storage. However, over time, the flask begins to smell like the contents in it.
• Type of fluid supply
  . The most popular is the valve (for classic models). It has a screw connection and is screwed into the thermos. He can pour liquid through a special hole in the valve, which you just need to press. Thanks to this, practically no tea leaves will get into the cup. However, it often gets stuck in the valve and is difficult to wash out. Also, over time, the valve becomes loose and begins to retain heat less well. Screw connections and lids must be unscrewed in order to pour the contents, which is not always convenient. Some lids can act as cups, so these models eliminate the need to carry a mug with you. Some jugs use a pump-type water supply. Most often it is purchased for selling hot drinks on the market.

Additional "chips"

Thermoses can have the following “equipment”:

• Extra cups and bowls. Some classic and food models may come with plastic containers and cups, which will come in handy if the contents are prepared for several people.
• Case and shoulder strap. Such structural elements simplify transportation if the thermos is taken on a hike.
• Carbine. The device is suitable for backpacks and bags where you can attach a thermos or a flask of water. Useful for hiking trips.

Conclusion

For work or school, a classic thermos of a certain volume (depending on needs) is suitable. Motorists should pay attention to mugs heated from the cigarette lighter. For a large family at home, a 1.5 - 2 liter thermos jug is suitable. And in order to always have a hot lunch with you, you need to purchase a food thermos with cutlery.
