How to remove the smell from a thermos: 4 ways

A thermos is a type of heat insulating dish that is used to keep the temperature of beverages and food at a constant level for a certain time. The service life of this type of cookware, the duration of heat preservation, the risk of an unpleasant odor and the complexity of its elimination directly depend on the device of the thermos and the material from which the flask is made.

Types of thermos

There are several options for dishes: a thermos for drinks and for food. A vessel that is designed to preserve food has a larger neck diameter and, as a rule, several containers. It can store both liquid and solid dishes. Sometimes it comes with a spoon, for which there is a special compartment. Get rid of the smell in a thermos with a wide neck is not difficult.

Things are different with thermos for drinks.Their neck is always very narrow, and the narrower it is, the longer the thermos will keep warm. In addition, some models are equipped with pneumatic pumps in the form of taps or special sealed covers with a hole that opens when pressed. It is very difficult to get rid of the smell in such a thermos.

Another model is a universal thermos. It is intended for both drinks and food. In such a thermos will have to get rid of the smell and food and drinks, which creates certain difficulties.

Bulb and body materials

The flask is a Dewar vessel made in a special way. There is an air gap between two identical walls. It maintains a constant temperature for a long time and prevents heat from escaping from the thermos into the environment. In the more expensive models, the interlayer is vacuum, they keep the heat longer.

The flask is made of glass or stainless steel. Glass heats up less, and, consequently, conducts less heat, and drinks remain hot for a long time. However, glass flasks are broken, which makes them less attractive.When washing such a vessel, it is necessary to avoid excessive friction, otherwise microcracks may appear. Weak points of the flask will quickly lead to loss of tightness.

Stainless steel flasks are more durable, they can be used daily, they are not afraid of high temperatures and friction.

For the manufacture of the outer shell using plastic or metal. In stainless steel thermoses, the outer layer of the flask is the body.
