Brief description of graphic materials

The essence of the invention is clarified by the drawing, which shows a schematic view of the glass.

Implementation of the invention

A self-heating glass works as follows:

The work of a self-heating glass is based on the flow of an exothermic reaction: the body of the glass (with double walls) consists of two hermetically welded parts (body and heating chamber). The outer part (10) is insulated from the inside with a layer of heat-insulating urethane foam (4). At the bottom of the part is a bellows compression button (8) with a high pressure silicone seal (9). The outer part (11) consists of a corrugated chamber designed for heated liquid containing 175 ml of liquid, and a central cone-shaped region (1) for water required during an exothermic reaction, which is closed by a waterproof membrane (5). The hermetically sealed area of external and internal parts is designed for chemical reactions and chemical elements. Calcium chloride weighing 30-60% and caustic soda weighing 3060% take part in the chemical reaction. Caustic soda is taken in the form of granules and powder (in a ratio: 1: 1). The area dedicated to the chemical reaction is separated by a water-soluble membrane (2) that separates the calcium chloride and caustic soda into upper and lower (separate) sections. To protect the glass from unintended use, the bottom of the button is protected from the outside with a paper film (7).

A three-stage exothermic reaction allows the liquid to warm up for 3-5 minutes, the liquid temperature reaches 65-76 ° C and remains after the end of the reaction for another 15 minutes.

The work of a self-heating glass is as follows: The button on the bottom is pressed and shaken for 5 seconds, then the glass is turned upside down and the reaction is expected for 4-5 minutes. Upon completion of the heat transfer, the glass is turned over to its original position, the transparent protective cover and aluminum foil are opened, and the glass is ready for use. The high data of the invention are explained by original solutions and non-standard technological equipment created for it.

The self-heating glass has a body. The body is made of food grade poly

- 1 038660 propylene heating chamber with a bottom part with a button. Then, between it and the heating chamber, a membrane is installed with the possibility of rupture, and a reagent with the ability to heat and a liquid reagent are used as components of the energy element. The side walls of the body are made hollow, the outer wall of the body is covered from the inside with heat-insulating foam urethane (0.071.0 cm thick), and the inner walls from the side of the heating chamber are made corrugated. The tip of the button, directed to the membrane, is made pointed, and a cast piece made of caustic soda, which is a reagent with heating properties, is attached to the side walls of the cavity in the upper part of the heating chamber in the form of a ring. The upper edge of this part is the cavity of the side walls, a water-soluble membrane is divided into upper and lower sections, the upper section is filled with calcium chloride, which is a reagent with a heating property, and the lower section is filled with caustic soda in granules and in the form of a powder, the heating chamber is filled with 1-10% an aqueous solution of food grade salt, which is a liquid reagent. Moreover, the heating chamber is made of food grade polypropylene, the heating chamber has the form of a truncated cone and calcium chloride and caustic soda, which are reagents with heating properties, are taken in the following ratios of ingredients, wt%:

calcium chloride 30.0-60.0 caustic soda 30.0-60.0.

A three-stage exothermic reaction allows the liquid to warm up for 3-5 minutes, the temperature of the liquid reaches 65-76 ° C and remains after the end of the reaction for another 15 minutes. Within 3-5 minutes, the released heat is transferred to the contents of the glass. This self-heating glass can also be used at temperatures from -5 to -4 ° C. As a result, we get a self-heating glass that can be used in different weather conditions and in a hot state.
