Description

Technical Field

[0001] This utility model belongs to the technical field of takeaway insulated bags, specifically a multi-layer takeaway insulated bag with independently partitioned storage cavities. Background Technology

[0002] With social development, food delivery services have become increasingly sophisticated. During delivery, takeout containers are typically placed in insulated bags. As functional packaging, these bags primarily function to keep food hot or cold by preventing heat exchange, effectively preventing temperature changes during transport from affecting the taste. They are an essential accessory for food delivery.

[0003] In existing technologies, most takeaway insulated bags have a single cavity structure. When delivering multiple meals, soup leakage and mixed flavors are likely to occur. In addition, different meals require different insulation and cooling temperatures. A single cavity cannot meet the differentiated temperature control needs, which affects the quality of the food and causes inconvenience to the user's dining experience.

[0004] Therefore, this utility model provides a multi-layer takeaway insulated bag with independently partitioned storage cavities. Utility Model Content

[0005] To address the shortcomings of existing technologies and solve the problems that most takeaway insulated bags have a single cavity structure, which can easily lead to leakage of soup and mixing of flavors when delivering multiple meals, and that different meals require different insulation and cooling temperatures, a single cavity cannot meet the differentiated temperature control needs, affecting the quality of the food and causing inconvenience to the user's dining experience.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The multi-layer takeaway insulated bag with independent partitioned storage cavity of this utility model includes an insulated bag body, a handle on the insulated bag body, an insulated interlayer on the inner wall of the insulated bag body, a pair of hook and loop fasteners fixed to the inner walls of the insulated interlayer, a pair of heat insulation plates inside the insulated bag body, and hook and loop fasteners fixed to the top two sides of the heat insulation plates, the hook and loop fasteners being adhered to the pair of hook and loop fasteners.

[0007] Preferably, the thermal insulation layer includes a heat insulation layer disposed on the inner wall of the thermal insulation bag, a heat insulation layer disposed on the inner wall of the heat insulation layer, and a waterproof layer disposed on the inner wall of the heat insulation layer.

[0008] Preferably, the heat insulation layer is made of aluminum foil composite film with a thickness of 0.10mm-0.15mm. The heat insulation layer is designed to specifically block radiative heat transfer, making up for the insufficient protection of heat radiation by a single heat insulation layer, improving the overall heat insulation efficiency. The thickness is moderate, balancing performance and ease of use, avoiding the problem of the material being too stiff due to excessive thickness or the reflective layer being damaged due to excessive thinness.

[0009] Preferably, the insulation layer is made of pearl cotton with a thickness of 1.2cm-1.8cm. The heat insulation layer is designed to specifically block radiative heat transfer, making up for the insufficient protection of heat radiation by a single insulation layer, improving the overall insulation efficiency. The thickness is moderate, balancing performance and ease of use, avoiding the problem of the material being too stiff due to excessive thickness or the reflective layer being damaged due to excessive thinness.

[0010] Preferably, the waterproof layer is made of thermoplastic polyurethane with a thickness of 0.08mm-0.12mm. By setting the waterproof layer, water absorption by the insulation layer is prevented, ensuring the long-term stable operation of the insulation interlayer. It is thin and light, does not occupy the effective space inside the bag, and the material is wear-resistant and suitable for frequent use.

[0011] Preferably, the insulated bag is provided with a sealing strip, and a double-sided adhesive strip is attached to one side of the sealing strip.

[0012] The beneficial effects of this utility model are as follows: 1. The present invention relates to a multi-layer takeaway insulated bag with independently partitioned storage cavities. By using hook and loop fasteners, the heat insulation board can be fixed inside the insulated bag body, dividing it into different storage cavities. This solves the problem that in the prior art, takeaway insulated bags are mostly single-cavity structures, which are prone to leakage of soup and mixing of flavors when delivering multiple meals. In addition, different meals require different insulation and cold preservation temperatures, and a single cavity cannot meet the differentiated temperature control needs, affecting the quality of the food and causing inconvenience to the user's dining experience.

[0013] 2. The multi-layer takeaway insulated bag with independent compartment storage chambers described in this utility model achieves heat preservation from all dimensions of "reflection-blocking-protection" through the three-layer structure, which can meet the needs of short-distance takeaway delivery for both hot and cold meals. The materials of each layer meet food contact safety standards, and there is no migration of harmful substances, thus ensuring food safety. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 4 As shown in the figure, a multi-layer takeaway insulated bag with an independent compartmentalized storage cavity according to an embodiment of the present utility model includes an insulated bag body 1, a handle 2 on the insulated bag body 1, an insulated interlayer 3 on the inner wall of the insulated bag body 1, a pair of hook and loop fasteners 4 fixed to the inner wall of the insulated interlayer 3, a pair of heat insulation plates 5 inside the insulated bag body 1, and hook and loop fasteners 6 fixed to the top two sides of the heat insulation plates 5, the hook and loop fasteners 6 being adhered to the pair of hook and loop fasteners 4.

[0018] During operation, the heat insulation plate 5 can be fixed inside the insulated bag body 1 by attaching the hook-and-loop fastener 6 and the loop fastener 4. This creates different storage compartments, thus solving the problem that in the existing technology, most takeaway insulated bags have a single cavity structure, which easily leads to leakage of soup and mixing of flavors when delivering multiple meals. Furthermore, different meals require different insulation and cold preservation temperatures, and a single cavity cannot meet the differentiated temperature control needs, affecting the quality of the meals and causing inconvenience to the user's dining experience.

[0019] The thermal insulation layer 3 includes a heat insulation layer 7 disposed on the inner wall of the thermal insulation bag, a heat insulation layer 8 disposed on the inner wall of the heat insulation layer 7, and a waterproof layer 9 disposed on the inner wall of the heat insulation layer 8.

[0020] During operation, the three-layer structure provides insulation from all dimensions of "reflection-blocking-protection," enabling hot and cold meals to meet the needs of short-distance takeout delivery. All layers are made of materials that meet food contact safety standards, with no harmful substances migrating, ensuring food safety.

[0021] The heat insulation layer 7 is made of aluminum foil composite film with a thickness of 0.10mm-0.15mm.

[0022] During operation, the heat insulation layer 7 is designed to specifically block radiative heat transfer, making up for the insufficient protection of heat radiation by the single heat insulation layer 8, thereby improving the overall heat insulation efficiency. The thickness is moderate, balancing performance and ease of use, avoiding the problem of the material becoming rigid due to excessive thickness or the reflective layer becoming damaged due to excessive thinness.

[0023] The insulation layer 8 is made of pearl cotton and has a thickness of 1.2cm-1.8cm.

[0024] During operation, the core of the insulation layer 8 blocks heat conduction and is the main insulation component of the insulation interlayer 3, ensuring stable temperature inside the bag, preventing deformation over long-term use, and extending the service life of the insulation bag.

[0025] Waterproof layer 9 is made of thermoplastic polyurethane with a thickness of 0.08mm-0.12mm.

[0026] During operation, the waterproof layer 9 prevents the insulation layer 8 from absorbing water, ensuring the long-term stable operation of the insulation interlayer 3. It is thin and light, does not occupy the effective space inside the bag, and is made of wear-resistant material, making it suitable for frequent use.

[0027] The insulated bag is equipped with a sealing strip 10, and a double-sided adhesive strip 11 is attached to one side of the sealing strip 10.

[0028] During operation, the sealing strip 10 at the opening of the insulated bag is folded in half, so that the double-sided adhesive strip 11 on one side of the sealing strip 10 adheres to the surface on the other side of the bag opening, thus quickly sealing the bag opening.

[0029] Working principle: A constant temperature barrier is constructed through a three-layer structure: the heat insulation layer 7 (aluminum foil composite film) first reflects the infrared heat radiated outward by the food inside the bag, while blocking the radiation of heat from the external environment into the bag; the small amount of heat that is not reflected is transferred to the heat insulation layer 8 (pearl cotton), where the still air in the sealed air bubbles blocks heat conduction and slows down heat loss or entry; the waterproof layer 9 (thermoplastic polyurethane) prevents soup or water inside the bag from penetrating into the heat insulation layer 8, avoids the heat insulation layer 8 from losing its heat insulation performance after absorbing water, and keeps the inside of the interlayer dry.

[0030] The heat insulation layer 7 uses the high reflectivity of the aluminum foil composite film surface (reflecting more than 90% of infrared rays) to reflect the heat radiation generated by the food inside the insulated bag back into the bag, while also reflecting the heat radiation from the external environment (such as high temperatures in summer and direct sunlight), reducing temperature changes caused by radiative heat transfer; the thickness of 0.10mm-0.15mm ensures the reflective effect while maintaining the flexibility of the material, so as not to affect the folding and storage of the insulated bag.

[0031] The insulation layer 8 uses the honeycomb-like closed-cell structure inside the pearl cotton to seal in a large amount of still air (the thermal conductivity of air is only 0.026W / (m•K)). When heat attempts to transfer between the inside and outside of the bag through conduction, the still air forms a "heat insulation barrier" that significantly slows down the rate of heat conduction. The thickness of 1.2cm-1.8cm ensures that there is enough bubble layer to achieve efficient heat insulation, while avoiding excessive thickness that would increase the weight and storage volume of the bag.

[0032] The waterproof layer 9, through the dense molecular structure of thermoplastic polyurethane, prevents leaked soup (such as soup noodles or porridge) from penetrating into the insulation layer 8; its thickness of 0.08mm-0.12mm ensures waterproofness while allowing the material to be breathable, thus releasing condensed moisture inside the bag and preventing the food from getting damp; the non-stick surface makes it easy to clean, and oil stains can be removed by wiping with a damp cloth.

[0033] By aligning and pressing the hook-and-loop fasteners 6 on both sides of the top of the heat insulation plate 5 with the rough-surface hook-and-loop fasteners 4 on the inner wall of the insulation layer 3, a pair of heat insulation plates 5 are horizontally fixed inside the body of the heat-insulating bag 1. The distance between the two heat insulation plates 5 can be adjusted according to the quantity of food and temperature requirements, dividing the inside of the heat-insulating bag into 1-3 independent storage compartments, so as to realize the partitioned storage of food at different temperatures (such as hot food and cold drinks). If it is necessary to adjust the partitions or remove the heat insulation plates 5, simply apply a pulling force to separate the hook-and-loop fasteners 4.
