Thermoses with a pump: description and choice

More than a hundred years have passed since the German entrepreneur Reinhold Burger invented the thermos. This universal household appliance is designed to store liquid at a constant temperature, which may be lower or higher than the ambient temperature. To date, there are many varieties of thermoses that have a very convenient and uncomplicated design. One of these options is a thermos with a pump.

A tube is placed inside the thermos with a pneumatic pump, and the end of the pump comes through the hole to the lid. To turn on the mechanism, press a special button or lever - after that the liquid will come out. In expensive models, there is a dispenser that sets the amount of drink poured at a time. In order to stop pouring liquid, you need to set the button or lever to the appropriate position.

Thus, a thermos with an air pump is a system that keeps the liquid inside the thermos at the required temperature for a long time, because there is no need to unscrew the lid. This means that the contents of the container are not subjected to cooling or heating.

Pump thermoses, like all household appliances, have their advantages and disadvantages. The advantages of using thermoses with a pneumatic pump include the following points:

• keep the required temperature of the liquid for quite a long time;
• this type of thermos is spacious and has a wide convenient neck;
• the design can be used by people who, due to age, cannot unscrew and screw the lid tightly;
• the locking system in such a thermos helps prevent spilling of liquid;
• thanks to the rotating base, the container does not need to be lifted to put it at a different angle - it can be rotated on the table with a slight movement of the hand.

To choose a high-quality and safe thermos with a pump, you need to carefully study the advice of experts.

• It is worth remembering: the larger the volume of the flask, the longer the drinks will keep warm or cold.
• It is necessary to carefully inspect the thermos for scratches, cracks and chips.
• You need to open the lid and smell it - a quality product should not have an unpleasant odor.
• Be sure to check the operation of the buttons or levers.
• A thermos with a pneumatic pump with a volume of 2 liters is convenient to transport in a car, and a three-liter version is perfect for business meetings, negotiations and other official events.
• The cost of a thermos with a pump, as a rule, depends on the popularity of the manufacturer, the material of manufacture and volume. High-quality and safe models of trusted brands cannot be cheap.
• To check the quality of the vacuum, pour boiling water into the container and leave for 24 hours. If the temperature of the liquid in a day is below 55 degrees, then the thermos does not hold heat well.

In order for the thermos with pump to last as long as possible, you should pay attention to some details.

• Before the first use, the container should be thoroughly washed.
• Before pouring the liquid, it is necessary to warm the flask with boiling water. To do this, leave boiling water in it for half an hour, and then drain it and fill it with the desired liquid.
• It must be remembered that only water, tea or coffee can be poured into a thermos with a pneumatic pump. In no case should you pour carbonated drinks inside, as carbon dioxide damages the metal.
• Do not use thick drinks, teas with fruits or leaves, so as not to clog the pump.
• It is not recommended to pour too much liquid - at least 1 cm should remain to the edge of the neck.
• The pump needs to be flushed and cleaned periodically.
• Do not wash the product with alkali solutions.
• Store the pump thermos in an upright position with the lid loosely closed.

Modern thermoses with pneumatic pump are easy to operate, do not require opening the lid, and the protective pump reliably prevents liquid from spilling.
