Description

Heat-insulation lunch box

Technical Field

The utility model relates to a lunch box, in particular to a heat-preservation lunch box.

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 heat preservation lunch-box, it has from taking the heat source and the better advantage of heat preservation effect.

The utility model provides a heat preservation lunch-box includes the lunch-box casing, holds container, lid, the surface of lunch-box casing is equipped with the recess that is used for placing and holds the container, the lateral wall of recess is pasted and is had the self-heating body, be equipped with the stock solution chamber that surrounds the recess in the lunch-box casing, the surface of lunch-box casing still is equipped with the communicating inlet in stock solution chamber, it pastes in the self-heating body to hold the container, inlet opening 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, heat preservation lunch-box pack into the meal through holding the container, pack into hot water through the stock solution chamber, utilize the temperature of hot water itself to keep warm to the meal, prolong 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, so that heat emitted by the self-heating body can be fully utilized, not only can the meal be heated, but also soup can be heated, the uniformity of the heated meal is improved through the liquidity of the soup, and the taste of the meal is improved. And the hot air can flow between the containing container and the box cover, so that the top surface of the meal is heated, and the uniformity of the heated meal is further improved.

Furthermore, along the opening edge of the groove, the self-heating bodies are distributed on the side wall of the groove at equal intervals, the adjacent self-heating bodies, the containing container and the inner wall of the groove form an air channel, and the air channel is communicated with the outside. The contact probability of the self-heating body and air is increased through the air duct, and the heating efficiency of the self-heating body is improved.

Further, from the hot body including the articulamentum that sets gradually on the recess inner wall, self-heating powder, ventilated membrane, non-woven fabrics, the blank pressing is done to the outer edge of self-heating body and is handled, the articulamentum adopts the ventilative material, the face that the articulamentum is close to the recess is equipped with the viscose, the face that the articulamentum is close to self-heating powder is equipped with water-soluble glue, it has the air isolated membrane to paste outward from the hot 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 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.

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 the groove. The containing container is made of food-grade silica gel, and the shape of the containing container is matched with 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.

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.

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