Description

Technical Field

[0001] The utility model relates to the technical field of food delivery bags, in particular to a food delivery bag with a cold and hot separation device. Background Art

[0002] Insulated food delivery bags are special bags designed to keep food temperature during the food delivery process. This bag uses special insulation materials and structural design to effectively isolate the outside temperature and reduce heat loss, thus ensuring that the food still maintains its original temperature and taste when it is delivered to consumers.

[0003] There are many materials to choose from for insulated food delivery bags, such as polypropylene, polyethylene, polyester, neoprene, etc.

[0004] In the prior art, insulated food delivery bags can generally only hold a single type of cold food or a single type of hot food. When hot food and cold food need to be delivered at the same time, multiple food delivery bags are required, which is wasteful and has high delivery costs. When cold food and hot food are put into the same delivery bag, it is easy to cause heat transfer between the two, resulting in poor insulation effect of cold food or hot food. Utility Model Content

The inner layer is a pearl cotton layer, which has a certain heat preservation performance and excellent buffering performance. It can effectively reduce the vibration and impact of food during transportation and protect the food from damage.

[0014] Preferably, in any of the above schemes, the bag body and the inner layer are bonded together by adhesive.

[0015] Adopting the above technical solution: the partition in this product divides the interior of the product into two storage areas, which can be used to place hot food and cold food respectively.

[0016] Preferably, according to any of the above schemes, when the seal closes the bag opening of the bag body, the bottom surface of the seal abuts against the top surface of the partition.

[0017] By adopting the above technical solution, when the bag mouth of the bag body is sealed, two areas inside the bag body can be isolated at the same time, so as to prevent heat transfer between hot food and cold food, thereby achieving the purpose of sealing and heat insulation.

Through the combination of aluminum foil and pearl cotton, an effective temperature isolation is formed between the hot food area and the cold food area, reducing the temperature transfer between the two areas, so that the food can maintain the original temperature for a longer time. At the same time, because an EVA hard board is wrapped in the interlayer, it is a lightweight material with a closed pore structure, which can effectively isolate the impact of external temperature changes on the interior. Wrapping the EVA hard board inside the interlayer can further enhance the insulation effect of the interlayer and ensure that the food maintains a constant temperature during the delivery process;

[0020] The surface of the interlayer is a layer with corrugated depressions, and the surface layer is an aerogel layer, which can significantly slow down the heat exchange between the food and the external environment, thereby maintaining the temperature of the food. The surface layer with corrugated depressions can further increase the complexity of the heat conduction path and improve the insulation effect.

[0034] like Figure 1-4 As shown, the food delivery bag with a hot and cold separation device comprises a bag body 1 and an inner layer 2, wherein the inner side of the bag body 1 is fixedly connected to the inner layer 2;

[0035] A seal 3 is fixedly connected to the bag opening of the bag body 1, and an adhesive tape 4 is fixedly connected to the edge of the seal 3;

[0036] The seal 3 can completely seal the bag opening of the bag body 1, the inner side of the inner layer 2 is fixedly connected with a partition 5, and the interior of the partition 5 is fixedly connected with a hard plate 6;

[0037] The two sides of the partition layer 5 are fixedly connected with the surface layer 7 , and the surface of the surface layer 7 is provided with a plurality of corrugated depressions 8 .

[0038] Embodiment 1: The material of the bag body 1 is an aluminum foil layer, and the material of the inner layer 2 is pearl cotton. This product is a food delivery bag that can be loaded with hot food and cold food such as cold drinks at the same time. The bag body 1 of this product is designed with the inner layer 2. The bag body 1 is an aluminum foil layer, which has excellent heat insulation performance and can effectively block the transfer of external heat and keep the temperature of the food stable. The inner layer 2 is a pearl cotton layer, which has certain heat preservation performance and excellent buffering performance. It can effectively reduce the vibration and impact of food during transportation and protect the food from damage.

[0039] Embodiment 2: The bag body 1 and the inner layer 2 are bonded by adhesive. The partition 5 in this product divides the interior of the product into two storage areas, which can be used to place hot food and cold food respectively. When the seal 3 closes the bag opening of the bag body 1, the bottom surface of the seal 3 abuts the top surface of the partition 5. When the seal 3 closes the bag opening of the bag body 1, it can simultaneously isolate the two areas inside the bag body 1 to prevent heat transfer between hot food and cold food, thereby achieving the purpose of sealing and heat insulation. The partition 5 is divided into two parts, an inner and an outer part, and is composed of an inner layer of pearl cotton wrapped in an outer layer of aluminum foil. The material of the hard board 6 is EVA, and the surface layer 7 is a nano aerogel layer. Since an EVA hard board 6 is wrapped in the partition 5, which is a lightweight material and has a closed pore structure, it can effectively isolate the influence of external temperature changes on the interior. Wrapping the EVA hard board 6 inside the partition 5 can further enhance the insulation effect of the partition 5 and ensure that the food maintains a constant temperature during the distribution process.

[0040] The working principle of the utility model is as follows:

[0041] Hot food is put into one side of the partition 5 in the bag body 1, and cold food is put into the other side of the partition 5 in the bag body, and the release film of the adhesive tape 4 is peeled off, and the adhesive tape 4 is adhered to the surface of the bag body 1, and the bag mouth of the bag body 1 is sealed with the seal 3;

[0042] When the seal 3 seals the bag mouth of the bag body 1, it can simultaneously isolate the two areas inside the bag body 1, preventing the heat transfer between hot food and cold food, and achieving the purpose of sealing and heat insulation. The bag body 1 is an aluminum foil layer with excellent heat insulation performance, which can effectively block the transfer of external heat and keep the temperature of the food stable. The inner layer 2 is a pearl cotton layer, which has certain heat preservation performance and excellent buffering performance, which can effectively reduce the vibration and impact of food during transportation and protect the food from damage.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] The food delivery bag with hot and cold separation device is provided with a partition layer 5, a hard plate 6, a surface layer 7, and a corrugated depression 8. A partition layer of pearl cotton wrapped in aluminum foil is installed in the middle of the food delivery bag, and an EVA hard plate 6 is wrapped inside the partition layer. Through the combination of aluminum foil and pearl cotton, an effective temperature isolation is formed between the hot food area and the cold food area, reducing the temperature transfer between the two areas, so that the food can maintain the original temperature for a longer time. At the same time, since an EVA hard plate 6 is wrapped in the partition layer 5, it is a lightweight material with a closed pore structure, which can effectively isolate the influence of external temperature changes on the interior. Wrapping the EVA hard plate 6 inside the partition layer 5 can further enhance the heat insulation effect of the partition layer 5, ensuring that the food maintains a constant temperature during the delivery process;

[0045] The surface of the interlayer 5 is a surface layer 7 with corrugated depressions 8, and the surface layer 7 is an aerogel layer, which can significantly slow down the heat exchange between the food and the external environment, thereby maintaining the temperature of the food. The surface layer 7 with corrugated depressions 8 on the surface can further increase the complexity of the heat conduction path and improve the insulation effect. Therefore, the food delivery bag has a hot and cold separation mechanism with better insulation effect. When cold food and hot food are placed in the food delivery bag at the same time, both can get better insulation and heat insulation without affecting each other. At the same time, it can also save delivery costs.
