In addition, in conditions, for example, of feeding several children at the same time, traveling, staying in a hospital or other adverse conditions (lack of water, including hot water, dishes for sterilizing containers, detergents for washing hands), it is impossible to prepare the mixture in compliance with all necessary hygiene requirements.

Therefore, infants are often fed with a pre-prepared mixture, the quality and temperature of which, as a rule, is significantly reduced by the time of feeding, which has a negative effect on children's health. Therefore, the diluted mixture is not subject to long storage.

The technical result of the claimed invention is the creation and implementation of an energy-saving product that accelerates and facilitates the process of preparing and warming up a product, for example, baby food, used to feed children, mainly infants, who are on artificial and / or mixed feeding while ensuring all safety, hygiene requirements, transportation and operation in the absence of opportunities for cooking and heating, in particular in the absence of power sources I, sanitary conditions).

The indicated result is achieved in that the mobile device for heating the product is characterized in that it is made in the form of a thermal bag with separate compartments and containers with baby food placed in these compartments, while the thermal bag contains a power source made in the form of a battery, a charger, and the compartments of the thermobag contain a heating element and an element that prevents heating, located at different levels, and the capacity for installation in the compartment is made in the form of two volumes divided between wallpaper with a rotary valve, in one of which there is water, and in the other a bulk mixture; however, the separation into volumes is performed in such a way that when the container is installed in the compartment, the heating element is in contact only with the volume where the water is located, while the volume with the bulk mixture is in contact with the element that prevents heating; in addition, the bag is equipped with a button to turn on the device and display the heating temperature with two LEDs configured to switch when the heating temperature reaches the set value.

A sterilized bottle for baby food is used as a container.

The thermobag is made of an antibacterial material containing silver nanoparticles.

The bottle contains a substance that prevents the growth of bacteria.

The thermobag is made of textile material.

The rotary valve is made of glass, plastic, silicone or latex, in which silver ions are introduced.

The thermobag is additionally equipped with a USB cable connected to it, one end of which is connected to the heating element, and the other end is connected to an electronic computing device that implements programs, for example, to carry out the next feeding of the baby or to indicate the temperature of one of the container volumes. Thanks to this connection, it is possible to ensure sequential or simultaneous heating of all containers placed in the thermal bag.

In addition, the thermobag can be additionally equipped with a timer, clock, display, allowing to warm up the product in a certain bottle by a given time and, as a result, save electricity.

The inventive device connected to a power source (not shown in the drawing) consists of a thermal bag 1 made of textile material and equipped with a charging device 2, an on / display button 3 with LEDs of different colors (not shown in the drawing). At least one compartment 4 is made in the bag’s cavity, into which a container 5 is installed — a baby food bottle, divided by a rotary valve 6, into two volumes, which are used for placement of various ingredients in them, in particular, in one of the volumes - the upper one - the liquid is placed, and in the other - the lower one - the loose mass is placed, for example, infant formula. In the bag, at the level of the upper volume of the bottle, a heating element 7 is installed, connected to the power source and in contact with this volume, and at the level of the second volume, an element 8 is installed that prevents heating and is made, for example, of carbon material, or Syntepon, or Tinsulate and in contact with the lower volume of the tank. A ceramic type heating element or an element made of wire or a sheet plate is used, for the manufacture of which nichrome is used.

In the thermal bag, any number of compartments in which containers are placed can be made. The most optimal number of baby bottles placed in a thermobag is an interval from six to thirty, corresponding to the daily norm of nutrition of one and / or several babies.

As a material for the manufacture of thermobags, an environmentally friendly material is used that has antibacterial properties and prevents the growth of bacteria due to the content of silver nanoparticles in its composition.

In addition, the device can be equipped with a clock, timer, display, etc. (not shown in the drawing). Thanks to the connection of these elements, it is possible to implement a program of sequential or simultaneous heating of the containers placed in the bag, a reminder of the next feeding of the child.

The implementation of the claimed invention is confirmed by examples of specific performance.

From a thermobag, a sterilized bottle for baby food, previously installed in it, is taken out, water is poured into the upper compartment, the bottle is turned over, then the required amount of the mixture is poured into the lower volume. If several bottles are placed in a thermal bag, each of them is filled in the same way. Filled containers are returned to the compartments. Check the location of the heating element, namely, its contact with the volume in which water is poured, and the location of the element that prevents heating, namely, its contact with the volume filled with the mixture. The bag is closed, connected to the power source by pressing the power / indication button, which is equipped with LEDs. In this case, the green light of the LED means that the liquid temperature reached 37 ° C and you can get a bottle, which is then turned upside down, turn the valve clockwise and, after the mixture has entered the volume with water, turn the valve in the opposite direction, shake the bottle . The mixture is ready to use.

While feeding several children from a thermobag, several heated bottles are taken out respectively.

When the indicator lights up in blue, it means that the water temperature is below 37 ° C and you need to connect the thermal bag to a power source, for example, using a wall outlet, a cigarette lighter, and a computer. Using a timer, you can not only set time intervals, but also receive sound signals that inform about the next feeding.
