Kaip pasirinkti žvejybos termosą

A thermos is designed to keep food and drinks hot or cold for a long time, regardless of the ambient temperature.

Some people use thermoses not only for preserving the temperature of cooked food and drinks, but also for cooking porridge and infusions.

The very first thermos was created in 1903 by Reingold Burger, based on the Dewar vessel (1892). A little later was registered trademark Thermos, under which the first products of this type began to be produced. Thermoses of this brand are still famous for their high quality of manufacture and excellent characteristics.

The thermos consists of a bulb with double walls, between which the air is pumped out (vacuum is created), which reduces heat conduction between the bulb and the outside environment.

Purpose of purchase

When buying a thermos, first of all, you should determine for what needs it is bought. Thermoses can be used at work, on trips and business trips, on trips to the countryside and walks in the woods, on fishing trips, at home. Depending on the conditions of use should be selected those or other characteristics of the dishes.

We in this article will dwell in detail on how to choose a thermos for fishing.

To begin with, answer for yourself two questions:

1) Is the thermos purchased for food or drinks?

2) The thermos will be used by one person or several people while fishing? Does it involve a large amount of hiking?

The answer to the first question will give an idea of what form of thermos to choose. Conditionally thermoses can be divided into several groups:

1) Thermos for drinks has a narrow neck.

2) Thermoses with a pneumatic pump are designed primarily for home conditions because of not the most compact design and inconvenience of use in nature.

3) Food thermoses are characterized by a wide neck. They are intended for storing food. Can have inside several plastic containers for different types of food.

4) Universal thermoses also have a wide neck and differ from food thermoses by the design of the cork (it has a narrower hole for pouring drinks).

The answer to question #2 will help you decide on the volume of the thermos. And also with how important is its weight, because with a large number of hiking transitions backpack should not be overloaded. And should pay attention to lighter models. Optimal for fishing will be the volume of 1-2 liters. Such a thermos will take its rightful place in the backpack and at the right moment will provide a hot tasty drink. A large volume of such containers, by the way, in addition to the quantity, there is another plus, it keeps the temperature longer.

The best material for this type of utensils for fishing will be stainless steel. Thermoses that are made of it, well retain temperature and have a high strength of the body. The presence of a handle will be a plus (although it will add a little weight to the product). If the handle folds compactly and will not interfere with the fact that you can put the thermos in a backpack.

In the store

1) Carefully read the information the manufacturer provides. On the package or in the instructions should be indicated, for what kind of products is suitable for this model, for how long it holds the temperature of the contents (the most important indicator, on it, of course, should be oriented in the first place).

2) Well inspect your potential purchase, it should not have scuffs, scratches, especially dents.

3) Check the package.

4) The thermos plug should fit snugly into the neck. Models with a screw cap keep the temperature longer. If the thermos is for drinks, you can choose a variant with a special button through which you can pour them. Such thermoses keep drinks hot longer and are easy to use. Although there is an opinion “the simpler, the better”. Such a button can fail, but the usual thread will serve for a guaranteed long time. Make sure that the thermos comfortably rests in your hand. If there is no handle, if there is one, it should also be as comfortable as possible to use.

5) Shake the thermos, during shaking there should not be any extraneous sounds.

6) From the inside, the product should not have any pungent unpleasant odors. If there are any, it is most likely made of low-quality materials unsuitable for food.

7) A pleasant and necessary, and often saving from frustration after an unsuccessful purchase, bonus will be the warranty on the product. So don’t forget to find out all the details about it in the store.

At home after purchase

Unfortunately, not all operations to check the quality of the product can be carried out when buying in the store. In order to finally make sure that you have bought a good thermos, you can do some more experiments at home.

1) Pour hot liquid into the thermos, after 15 minutes, check whether the body is not heated. If heated, it means that the thermos is defective and will not fulfill its main functions.

2) Fill the thermos with 100% boiling water, check the temperature of the liquid after 24 hours (in the characteristics of the thermos should be indicated what should be this temperature).

3) Check the tightness of the lid.

To keep liquids and any other food items hot for longer, it is best to fill the entire container, the smaller the container is filled, the faster the contents will cool down.

Care

If you want the thing to last as long as possible, then it certainly needs proper care. Do not forget to wash the product well after use. After washing, you need to leave the thermos open so that it dries completely.

A little about brands

Focusing on well-known, proven brands when choosing a thermos will not be superfluous, since their quality is confirmed by years of production and reviews of many buyers. Such brands include Thermos, Stanley, Arktika, Zojirushi, Tiger.

Happy shopping!
