Thermal insulation type basin mutton self-heating box

Abstract

This utility model relates to the field of food packaging technology, and in particular to a heat-insulating self-heating box for mutton soup. It includes an outer box body, with support blocks fixedly connected to the four corners of the top of the inner cavity of the outer box body. Each support block has a limiting groove on its top, into which an inner box body is fitted. A partition strip is fixedly connected to the inner cavity of the outer box body, and a heating pack is placed at the bottom of the inner cavity. The outer box body includes a main body, with a reinforcing mesh plate glued to its outer surface. During the heating process, heat is transferred to insulating particles, which absorb and store excess heat, converting a large amount of thermal energy into latent heat. After heating, the liquid paraffin-based PCM releases the stored latent heat and slowly solidifies, causing the mutton soup broth to drop from its boiling point to the optimal serving temperature (60°C) and extending the heat preservation time by 30-50 minutes. This greatly extends the heat preservation time of the food, ensuring the excellent taste of the mutton soup.

Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, specifically to a heat-insulating self-heating box for mutton soup. Background Technology

[0002] Food packaging refers to the sustainable packaging form that food companies create by rationally planning and packaging food to ensure its quality and reduce the risk of consumers coming into contact with it. Self-heating boxes are a type of food packaging. Their core principle is to generate high-temperature steam by reacting a built-in heating pack with water to heat the food. They are characterized by fast heating speed.

[0003] A search revealed that the announcement number is CN220299058U, and the name is "Anti-overflow High-efficiency Heat Transfer Self-Heating Box". It includes an outer shell, and an inner shell is placed inside the outer shell. Through research and analysis, it was found that although it can easily achieve the locking of the lid and the outer shell, preventing the lid from moving due to the boiling of soup, thus ensuring that the soup will not overflow, and can ensure normal venting while effectively preventing boiling soup from overflowing from the vent hole, it still has the following defects to a certain extent.

[0004] For example, insufficient heat insulation can easily cause burns during the process of placing and moving the heated high-temperature box, resulting in low safety. At the same time, it cannot keep soups such as mutton soup warm for a longer period of time. The short heat preservation time will cause the mutton soup to cool down quickly, affecting the taste. In order to solve the above technical problems, we have designed a heat-insulating self-heating box for mutton soup. Utility Model Content

[0005] The purpose of this utility model is to provide a heat-insulating self-heating box for mutton in a basin, which has better heat insulation and anti-scalding effect, avoids scalding during handling and movement, improves safety, and can keep the food warm for a long time, thus improving the taste. It solves the problems of unsatisfactory heat insulation and anti-scalding effect, easy scalding, low safety, short heat preservation time, and affecting the taste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat-insulating and heat-preserving self-heating box for mutton soup, comprising an outer box body, with support blocks fixedly connected to the four corners of the top of the inner cavity of the outer box body, a limiting slot formed on the top of the support block, an inner box body being fitted into the inner cavity of the limiting slot, a partition strip fixedly connected to the inner cavity of the outer box body, a heating pack placed at the bottom of the inner cavity of the outer box body, the outer box body comprising a box body, a reinforcing mesh plate glued to the outer surface of the box body, a heat-insulating pad glued to the outer surface of the reinforcing mesh plate, an aluminum foil heat-insulating layer glued to the outer surface of the heat-insulating pad, an outer shell plate glued to the outer side of the aluminum foil heat-insulating layer, and heat-insulating particles filling the inner cavity of the reinforcing mesh plate.

[0007] Preferably, the inner box includes a box body, a top plate is fixedly connected to the top of the box body, limit blocks are fixedly connected to the four corners of the bottom of the top plate, and limit grooves are formed at the four corners of the outer surface of the box body.

[0008] Preferably, each of the bottom surfaces of the outer box is fixedly connected to a heat-insulating vertical plate, and the number of the partition strips is several and they are evenly distributed.

[0009] Preferably, a fixing ring is fixedly fitted on the outer surface of the outer box, and anti-scalding handles are installed on both the left and right sides of the fixing ring via movable pins.

[0010] Preferably, a placement groove is provided at the bottom of the inner cavity of the box body, and limit baffles are fixedly connected to the left and right sides of the top of the placement groove.

[0011] Preferably, the insulating particles are paraffin-based composite phase change materials, and the insulating pad is EPP foamed polypropylene material.

[0012] Preferably, the top of the outer box is fitted with a lid, and each of the four corners of the top of the lid has an exhaust hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. During the heating process, the heat is transferred to the heat-insulating particles to absorb and store the excess heat. A large amount of heat energy is converted into latent heat and stored. When the heating is finished, the liquid paraffin-based PCM releases the stored latent heat and slowly solidifies, causing the mutton soup to drop from the boiling point to the optimal eating temperature (60℃) and extending the heat preservation time by 30-50 minutes. This greatly extends the heat preservation time of the ingredients and ensures the excellent taste of the mutton soup.

[0015] 2. By setting up a heat insulation pad and aluminum foil insulation layer, heat conduction can be effectively prevented and heat insulation performance can be improved, thus effectively avoiding burns. The anti-scalding handles on both sides can prevent direct contact with the box body when placing the self-heating box, making it easier to place and effectively improving the safety of use.

[0023] Please see Figures 1-6 A heat-insulating self-heating box for mutton soup includes an outer box body 1. Support blocks 10 are fixedly connected to the four corners of the top of the inner cavity of the outer box body 1. The support blocks 10 support and limit the position of the top plate 15. A limiting slot 12 is formed on the top of the support block 10. The limiting slot 12 allows the limiting block 14 at the bottom of the top plate 15 to engage and be positioned, preventing the box body 16 from swaying up and down inside the outer box body 1. An inner box body 8 is fitted into the inner cavity of the limiting slot 12. A partition strip 7 is fixedly connected to the inner cavity of the outer box body 1. The partition strip 7 limits the side position of the box body 16. Meanwhile, an air duct can be formed between two adjacent partition strips 7 to facilitate the upward exhaust of hot air. A heating pack 13 is placed at the bottom of the inner cavity of the outer box 1. The outer box 1 includes a box body 22. A reinforcing mesh plate 20 is glued to the outer surface of the box body 22. By setting the reinforcing mesh plate 20, the side wall support of the box body 22 can be strengthened on the one hand, and the insulation particles 23 can be stored conveniently on the other hand. An insulation pad 18 is glued to the outer surface of the reinforcing mesh plate 20. An aluminum foil insulation layer 21 is glued to the outer surface of the insulation pad 18. An outer shell plate 19 is glued to the outer side of the aluminum foil insulation layer 21. The inner cavity of the reinforcing mesh plate 20 is filled with insulation particles 23.

[0024] Please see Figure 4 The inner box 8 includes a box body 16. A top plate 15 is fixedly connected to the top of the box body 16. Limiting blocks 14 are fixedly connected to the four corners of the bottom of the top plate 15. Limiting grooves 17 are opened at the four corners of the outer surface of the box body 16. By setting the limiting grooves 17, the support block 10 can be easily inserted into its interior to prevent the box body 16 from rotating inside the outer box 1.

[0025] Please see Figure 1Each outer box 1 has a heat insulation vertical plate 2 fixedly connected to the bottom of its outer surface. By setting the heat insulation vertical plate 2, it is possible to prevent people from being burned when they touch the bottom of the outer box 1. There are several partition strips 7, which are evenly distributed.

[0026] Please see Figure 2 The outer surface of the outer box 1 is fixedly fitted with a fixing ring 3. By setting the fixing ring 3, the anti-scalding handle 6 can be easily installed. The anti-scalding handle 6 is installed on both the left and right sides of the fixing ring 3 through movable pins.

[0027] Please see Figure 3 The bottom of the inner cavity of the box body 22 is provided with a placement groove 11. By setting the placement groove 11, the heating pack 13 can be conveniently stored. The left and right sides of the top of the placement groove 11 are fixedly connected with limit baffles 9. By setting the limit baffles 9, the heating pack 13 can be prevented from moving out of the placement groove 11, thus playing a limiting role.

[0028] Please see Figure 5 and Figure 6 The heat-insulating particles 23 are paraffin-based composite phase change materials. The heat-insulating particles 23 are microcapsule powders with spherical particles of 10~50μm in diameter. The core is paraffin and the outer shell is PMMA or silica. The heat-insulating pad 18 is EPP foamed polypropylene material.

[0029] Please see Figure 1 The top of the outer box 1 is fitted with a lid 4, and each of the four corners of the lid 4 has an exhaust hole 5. By setting the exhaust hole 5, the hot air during the heating process can be easily discharged to the outside.

[0030] In use, after opening the lid 4, remove the inner box 8 from the outer box 1, pour the ingredients into the inner box 8, then add an appropriate amount of water to the outer box 1, and then place the inner box 8 containing the ingredients into the outer box 1 and close the lid 4. The heating pack 13 reacts with the water to heat the ingredients in the inner box 8. During the heating process, the heat is transferred to the heat-insulating particles 23 through the inner wall of the box body 22. Because the heat-insulating particles 23 have the characteristic of reversible solid-liquid phase change process to achieve efficient storage and release of heat energy, they absorb and store excess heat during the heating stage. The paraffin-based PCM changes from solid to liquid, and the temperature remains basically constant at the phase change point, converting a large amount of heat energy into latent heat storage. After heating is complete, as the temperature of the food inside the inner box 8 decreases, the liquid paraffin-based PCM releases its stored latent heat and slowly solidifies, causing the mutton soup to drop from its boiling point to the optimal eating temperature (60℃) and extending the heat preservation time by 30-50 minutes. This greatly extends the heat preservation time of the food, ensuring the best taste of the mutton soup. By setting up the heat preservation pad 18 and the aluminum foil insulation layer 21, heat conduction can be effectively prevented, improving heat insulation performance and effectively preventing burns. At the same time, by setting anti-scalding handles 6 on both sides, the self-heating box can be placed without direct contact with the box body, making it easier to place and effectively improving the safety of use.

[0031] In summary, this heat-insulating self-heating box for mutton soup, through the combined use of the outer box 1, anti-scalding handle 6, inner box 8, heat-insulating pad 18, reinforcing mesh plate 20, aluminum foil heat insulation layer 21, and heat-insulating particles 23, solves the problems of unsatisfactory heat insulation and anti-scalding effect, easy burns, low safety, short heat preservation time, and affecting the taste of food.
