Description

Self-heating lunch box capable of heating uniformly

Technical Field

The utility model relates to a lunch box, in particular to a self-heating lunch box with uniform heating.

Background

Taking-out and delivering food are a common dining mode, and time is saved for life of people, so that convenience is brought. However, in cold days, the food is cooled when being sent to the hands of customers, and the cooled food not only affects the taste and the appetite, but also is not beneficial to health to a certain extent, so that complaints and disputes caused by the cold food are also few. At present, the disposable lunch boxes disclosed in the patent publications are various in types, but the foam heat-insulating layer and the tin film layer are mainly used for heat insulation, so that the food is not heated by an external heat source, and the heat insulation effect is poor; in addition, in the self-heating type fast food box of CN2016101400299, a large amount of water is needed to be added into the self-heating powder, so that the self-heating powder is immersed in the water to generate a violent exothermic reaction, and the box is allowed to stand for a period of time to heat the meal. How to overcome the defects of the prior art, the design of a disposable heat-preservation lunch box with a heat source becomes a research object of the inventor.

SUMMERY OF THE UTILITY MODEL

Based on this, the utility model aims at providing a be heated even self-heating lunch-box, it has from taking the heat source and the better advantage of heat preservation effect.

The utility model provides an even self-heating lunch-box of being heated includes the lunch-box casing, holds container, lid, the surface of lunch-box casing is equipped with the first recess that is used for placing and holds the container, the bottom of first recess is equipped with the second recess that is used for placing the self-heating body, be equipped with the stock solution chamber that surrounds first recess, second recess in the lunch-box casing, the surface of lunch-box casing still be equipped with the communicating inlet in stock solution chamber, inlet department is equipped with the lid that is used for opening, closes the inlet, the lid is established on holding the container.

Compared with the prior art, hot even self-heating lunch-box is packed into the meal through holding the container, packs into hot water through the stock solution chamber, utilizes the temperature of hot water itself to keep warm to the meal, prolongs the heat preservation time of lunch-box. Then, when the temperature of the food and soup is not enough, the temperature of the food and soup can be raised by utilizing the heat generated by the self-heating body. In addition, the self-heating body is surrounded by the containing container and the liquid storage cavity, heat emitted by the self-heating body can be fully utilized, the liquid storage cavity is surrounded by the containing container, the heating uniformity of the meal can be improved, and the taste of the meal is improved.

Further, along the bottom of second recess to the direction at its top, from the heat body be equipped with articulamentum, self-heating powder, ventilated membrane, non-woven fabrics in proper order, do the blank pressing and handle from the heat body outer fringe, the articulamentum adopts ventilative material, the face that the articulamentum is close to second recess bottom is equipped with the viscose, the face that the articulamentum is close to self-heating powder is equipped with water-soluble glue, it has air isolation membrane to paste from the heat body. The self-heating powder is fixed in the bag formed by the connecting layer, the breathable film and the non-woven fabric by performing edge pressing treatment on the self-heating body, one side of the self-heating body is adhered to the bottom surface of the second groove, and the other side of the self-heating body is adhered with the air isolation film, so that the self-heating powder is effectively prevented from generating exothermic reaction with air.

Further, the self-heating powder is composed of iron powder, water, activated carbon powder, vermiculite powder and sodium chloride. On one hand, the iron powder and the sodium chloride are uniformly dispersed on the adhesive tape layer, on the other hand, the water in the air is fully absorbed by utilizing the extremely strong water absorbability of the activated carbon powder and the vermiculite, so that the exothermic oxidation reaction of the iron powder and the oxygen in the air is promoted to be catalyzed by the sodium chloride, and the speed of the exothermic oxidation reaction is promoted.

Further, the breathable film is a porous aluminum foil paper film. The porous structure can make air enter the breathable film to react with the self-heating powder, and the aluminum foil paper can block the heat radiation from the self-heating powder to be transferred outwards, so that the heat of the self-heating powder and the meal can be better stored.

Further, the air insulation film is cellophane.

Further, the edge of the air isolating membrane is provided with a tearing angle. The air isolation film is torn off through the tearing angle, so that the operation of a user is facilitated.

Furthermore, the box cover is arranged on the lunch box shell, and the containing container and the liquid inlet are both arranged between the box cover and the lunch box shell. When in use, the cover body can be taken away, so that the liquid storage cavity is communicated with the container, and the heat in the liquid storage cavity and the container is fully utilized.

Further, the bottom surface of the liquid storage cavity inclines downwards towards the liquid inlet direction. The soup in the liquid storage cavity is convenient to suck.

Furthermore, the containing container is made of soft materials capable of being turned outwards for cleaning, the containing container is made of food-grade silica gel, and the shape of the containing container is matched with that of the first groove. After the lunch box is eaten, the containing container is taken out, and the containing container is made of soft materials which can be turned outwards to be cleaned, so that the four corners of the lining of the lunch box can be better cleaned.

For a better understanding and an implementation, the present invention is described in detail below with reference to the accompanying drawings.
