Description

Technical Field

[0001] This utility model relates to the field of thermal insulation container technology, and in particular to a top cover for a thermal insulation bag. Background Technology

[0002] Insulated bags, as products with heat insulation functions, are often used in cold chain transportation, outdoor picnics, daily food carrying, or items that require temperature control. By blocking heat exchange, they maintain a relatively stable temperature environment inside the bag, meeting the special temperature requirements of the items.

[0003] In the structure of an insulated bag, the top cover is a key component affecting the overall insulation performance, sealing, and appearance. Currently, the outer layer of the top cover of most insulated bags is made of flexible material. While this material possesses good flexibility and adaptability, it lacks rigid support and is difficult to maintain a flat state on its own. Due to the inherent deformability of flexible materials and the fact that they are usually only simply restrained by the edges, failing to form an effective bond, the flexible outer layer cannot adhere tightly to the surface of the internal structure. After the product is manufactured, gaps easily remain between the outer layer and the internal structure, trapping air and resulting in an uneven outer surface, thus affecting the product's appearance and texture. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a top cover for an insulated bag. By optimizing the connection structure between the outer layer, the support plate, and the insulation combination plate, it effectively ensures the flatness of the outer layer's fit, improves the overall appearance and practicality of the insulated bag, and enhances structural stability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A top cover for an insulated bag includes an outer layer and an insulated assembly panel with an insulated function. The insulated assembly panel is provided with a support function part that contacts the outer layer to ensure the flatness of the outer layer. A constraint connection is formed between the outer layer and the insulated assembly panel to ensure that the outer layer adheres to the support function part.

[0007] Preferably, the outer layer has an adhesive layer on the side facing the support plate. The outer layer and the insulation composite board are connected by the adhesive layer to form a constraining connection between the outer layer and the insulation composite board. The adhesive layer is used to connect the outer layer and the insulation composite board, and at the same time, it constrains the outer layer, prevents it from deforming arbitrarily, and ensures the flatness of the outer layer.

[0008] Preferably, the supporting functional part is an independently set support plate, which is located between the outer layer and the insulation composite plate. The outer layer is attached to the support plate, so that the support plate can provide a supporting surface for the flexible outer layer, which can effectively prevent wrinkles from forming on the outer layer and stably maintain the flatness of the outer layer.

[0009] Preferably, the middle part of the adhesive layer is a cut-off hollow portion. The adhesive layer is set along the edge of the outer layer and is connected to the outer layer and the insulation panel respectively. By cutting off the middle part, the connection strength can be ensured while reducing unnecessary material usage.

[0010] Preferably, the support plate is smaller than the insulation composite board, leaving gaps around the support plate. The adhesive layer at the outer edge is connected to the edge of the insulation composite board through the gaps. Since the support plate is smaller than the insulation composite board, it can avoid the support plate blocking the edge of the insulation composite board and allow the adhesive layer on the outer edge to contact the insulation composite board for high-frequency pressing connection.

[0011] Preferably, the outer layer has a edging, which cooperates with the outer layer to form an accommodating space. The support plate and the insulation combination plate are both located within the accommodating space. Through the space formed by the edging and the outer layer, the outer layer is fitted onto the support plate and the insulation combination plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model connects the outer layer and the insulation panel through an adhesive layer, which forms a constrained connection to the outer layer and solves problems such as easy bulging and non-adhesion of the flexible outer layer, ensuring the flatness of the outer layer. In addition, a support plate that directly contacts and cooperates with the outer layer is provided to further ensure the flatness of the outer layer. The support plate is smaller than the insulation panel to avoid obstructing the edges, so that the adhesive layer of the outer layer can be stably connected to the edge of the insulation panel. The edge banding can form a receiving space with the outer layer, so that the components can be neatly assembled together. Attached Figure Description

[0023] Example:

[0024] Please see Figure 1-3 A top cover for an insulated bag includes an outer layer 1 and an insulated composite plate 5 with an insulated function. The insulated composite plate 5 is provided with a support function part that contacts the outer layer 1 to ensure the flatness of the outer layer 1. A constraint connection is formed between the outer layer 1 and the insulated composite plate 5 to ensure that the outer layer 1 is attached to the support function part.

[0025] An adhesive layer 3 is provided on the side of the outer layer 1 facing the support plate 4. The outer layer 1 and the insulation composite plate 5 are connected by the adhesive layer 3 to form a constraint connection between the outer layer 1 and the insulation composite plate 5. The adhesive layer 3 is used to connect the outer layer 1 and the insulation composite plate 5, and at the same time, it constrains the outer layer 1, which can prevent the outer layer 1 from deforming at will and ensure the flatness of the outer layer 1.

[0026] The supporting functional part is an independently set support plate 4, which is located between the outer layer 1 and the thermal insulation composite plate 5. The outer layer 1 is attached to the support plate 4, so that the support plate 4 can provide a supporting surface for the flexible outer layer 1, which can effectively prevent wrinkles from forming on the outer layer 1 and stably maintain the flatness of the outer layer 1.

[0027] The middle part of the adhesive layer 3 is a hollow part 31 that has been cut off. The adhesive layer 3 is set along the edge of the outer layer 1 and is connected to the outer layer 1 and the insulation combination board 5 respectively. By cutting off the middle part, the connection strength can be ensured while reducing the use of unnecessary materials.

[0028] The support plate 4 is smaller than the insulation composite plate 5, leaving gaps around the support plate 4. The adhesive layer 3 at the edge of the outer layer 1 is connected to the edge of the insulation composite plate 5 through the gap. Since the support plate 4 is smaller than the insulation composite plate 5, it can avoid the support plate 4 from blocking the edge of the insulation composite plate 5, and allow the adhesive layer 3 on the edge of the outer layer 1 to contact the insulation composite plate 5 for high-frequency pressing connection.

[0029] The outer layer 1 has an edge band 2, which cooperates with the outer layer 1 to form an accommodating space. The support plate 4 and the insulation combination plate 5 are both located in the accommodating space. Through the space formed by the edge band 2 and the outer layer 1, the outer layer 1 is fitted onto the support plate 4 and the insulation combination plate 5 through this space.

[0030] The outer layer 1 can be made of PVA material, and the adhesive layer 3 can be made of PVEA adhesive material. It is cut into a hollow center 31, following the shape of the outer layer 1 edge. The adhesive layer 3 is then bonded to the inner side of the outer layer 1 using high-frequency pressing, thus fixing the adhesive layer 3 to the corresponding position on the side of the outer layer 1 facing the support plate 4. The insulation panel 5 is a board covered with insulation material, with the side of the insulation panel 5 connected to the adhesive layer 3 facing upwards. The cut support plate 4 is then placed on the upward-facing side of the insulation panel 5, and the outer layer 1 is then shaped by the edge binding 2. The support plate 4 is smaller than the insulation composite plate 5, allowing the edge of the insulation composite plate 5 to be exposed without obstruction. The adhesive layer 3 on the edge of the outer layer 1 corresponds to the edge of the insulation composite plate 5. Then, the insulation composite plate 5 and the adhesive layer 3 are connected together by high-frequency pressing, so that the edge of the outer layer 1 can be connected with the insulation composite plate 5, forming a constrained connection to the outer layer 1. This ensures the flatness of the outer layer 1, and the support plate 4 can provide surface support to the outer layer 1, further ensuring the flatness of the outer layer 1.

[0031] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
