Description

Technical Field

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

[0002] Insulated bags are widely used in daily life and cold chain transportation. They generally consist of an outer layer, an inner liner, and intermediate insulation material, achieving insulation through a multi-layered structure. To enhance practicality and stability, a bottom plate is often connected inside the inner liner to support the items and improve the structural strength and load-bearing capacity of the bottom of the inner liner.

[0003] In traditional thermal pack production and assembly, the base plate is installed by first placing the structure formed by the insulation board inside the outer layer. A mounting slot at the bottom accommodates the base plate. The conventional procedure is to first place the base plate and the insulation board structure inside the outer layer, and then sew the inner liner. However, in actual use, due to the lack of an effective fixed connection between the inner liner and the base plate, the inner liner is prone to loosening or even being pulled up, failing to remain stable in the preset position. During sewing, it is prone to movement and lacks a clear reference point, easily causing the surrounding material to fail to tighten and adhere to the internal structure. This results in a loose and poorly fitted inner liner, affecting the insulation effect and structural stability. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a novel thermal insulation bag. By optimizing the connection structure between the inner liner and the base plate, it solves the problem of loose inner liner and improves production efficiency and product stability.

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

[0006] A novel thermal insulation bag includes an outer cover and an insulation panel disposed on the inner side of the outer cover, and also includes an inner liner fixing structure. The inner liner fixing structure includes a bottom plate and an inner liner fixed to the bottom plate. The inner liner includes a bottom surface fixed to the bottom plate and a side surface for covering the insulation panel. The bottom plate is fixed by a limiting structure disposed at the bottom end of the insulation panel, and the upper end of the side surface is fixed to the upper end surface of the insulation panel.

[0007] Preferably, the bottom surface of the inner liner wraps around and is fixedly connected to the bottom plate, so that the inner liner and the bottom plate form an integral structure. Through the fixed connection between the bottom surface of the inner liner and the bottom plate, the inner liner can be fixed and limited, avoiding the problem of the inner liner being pulled up during sewing and preventing the sewn inner liner from being loose.

[0008] Preferably, the limiting structure at the bottom of the insulation panel is an installation groove for installing the base plate. The base plate is adapted to the installation groove, and the adaptation installation structure between the installation groove on the insulation panel and the base plate enables the base plate to form a stable fit with the insulation panel.

[0009] Preferably, the inner liner has outstretching wings at the four corners of its upper side surface. The outstretching wings extend outward along the edge of the side surface. The outward-extending outstretching wings at the four corners of the inner liner provide structural convenience for sewing the inner liner. The extended design of the outstretching wings can naturally open the sewing opening of the inner liner during sewing, solving the problems of difficulty in opening the opening and limited operating space when sewing traditional inner liners. This reduces the difficulty of sewing and helps to improve production efficiency and sewing quality.

[0010] Preferably, the expansion wing is located at the end of the upper side of the inner liner away from the bottom plate, limiting the expansion wing to the end away from the bottom plate, so that the seam opening of the expansion wing above the inner liner corresponds to the seam opening above the outer cover.

[0011] Preferably, the upper side of the inner liner away from the bottom plate is provided with a positioning groove. The presence of the positioning groove can guide workers to quickly align the various parts of the inner liner during sewing, reduce sewing misalignment caused by manual alignment errors, and improve the consistency and standardization of the product.

[0012] Preferably, the positioning groove is located in the middle of the side away from the bottom plate, and the positioning groove is located in the middle of the inner liner away from the bottom plate. This makes the positioning function of the positioning groove more symmetrical and accurate. The positioning groove in the middle position can serve as a reference point to help the materials of each part of the inner liner's peripheral wall to be aligned during sewing, avoiding misalignment and further ensuring sewing accuracy. At the same time, it facilitates workers to quickly identify and operate, improving production efficiency.

[0013] Preferably, the inner liner is made of multiple inner layer materials sewn together. Among the multiple inner layer materials, some inner layer materials are arranged around to form the side surface, and the remaining inner layer materials form the bottom surface. This clarifies that the inner liner is made of multiple inner layer materials sewn together, making the structural composition of the inner liner clearer. When sewing the inner liner, the main body of the inner liner can be made by sewing together four inner layer materials surrounding the four sides and one inner layer material located at the bottom.

[0014] Preferably, each inner layer material surrounding the side surface is provided with a seam flap and a positioning groove, and each inner layer material surrounding the perimeter wall is provided with a seam flap and a positioning groove, so that the function of the seam flap and the positioning groove covers the entire perimeter wall of the inner liner. This comprehensive arrangement ensures that each part of the perimeter wall can obtain the operational convenience brought by the seam flap and the precise alignment brought by the positioning groove during sewing.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model's insulation bag uses an inner liner to wrap around a base plate, forming an integrated structure. This solves the problem of loose inner liner and easy pulling during sewing, which can lead to sagging. The material of the inner liner's perimeter wall can be tightened by the fixed bottom structure, ensuring a tight fit between the inner liner and the interior, and ensuring a tight fit between the inner liner and the insulation panel, thus improving insulation and sealing. The addition of seam flaps can enlarge the sewing opening, and the positioning grooves assist in precise alignment, reducing sewing difficulty and improving production efficiency and product consistency.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0027] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0028] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0029] Example:

[0030] Please see Figure 1-6 A novel thermal insulation bag includes an outer cover 1 and a thermal insulation panel 3 disposed on the inner side 22b of the outer cover 1. It also includes an inner liner fixing structure 2, which includes a bottom plate 21 and an inner liner 22 fixed to the bottom plate 21. The inner liner 22 includes a bottom surface 22a fixed to the bottom plate 21 and a side surface 22b for covering the thermal insulation panel 3. The bottom plate 21 is fixed by a limiting structure disposed at the bottom end of the thermal insulation panel 3, and the upper end of the side surface 22b is fixed to the upper end surface of the thermal insulation panel 3.

[0031] The bottom surface 22a of the inner liner 22 wraps around and fixes the bottom plate 21, so that the inner liner 22 and the bottom plate 21 form an integral structure. This integral structure can be pulled and tightened when sewn with the outer cover 1, so that the inner liner 22 can fit the insulation panel 3. When the inner liner is fixed, the bottom of the inner liner 22 is fixedly connected to the bottom plate 21. The fixing connection method can be sewing, gluing, etc., which directly solves the problem of the inner liner 22 being loose and avoids the problem of the inner liner 22 being pulled up during sewing, thus preventing the sewn inner liner 22 from being loose.

[0032] The limiting structure at the bottom of the insulation panel 3 is an installation groove 31 for installing the base plate 21. The base plate 21 is fitted with the installation groove 31. The cooperation between the installation groove 31 and the base plate 21 enhances the overall structural stability. The depth of the installation groove 31 is matched with the thickness of the base plate 21 to avoid heat loss caused by gaps between the base plate 21 and the installation groove 31. At the same time, it prevents the base plate 21 from shaking after installation, reduces heat transfer between the insulation panel 3 and the base plate 21, and enhances the overall insulation effect.

[0033] A positioning groove 24 is provided on the side 22b of the inner liner 22 away from the bottom plate 21. The positioning groove 24 is located in the middle of the side 22b away from the bottom plate 21. The positioning groove 24 can play a role in precise positioning during sewing, ensuring the accuracy and consistency of the sewing.

[0034] Furthermore, the inner liner 22 is provided with expansion wing 23 at the four corner edges. The expansion wing 23 extends outward along the edge and is located at the end away from the bottom plate 21. The inner liner 22 is made of multiple inner layer materials. Among the multiple inner layer materials, some inner layer materials are arranged around to form the side surface 22b, and the remaining inner layer materials form the bottom surface 22a. Each inner layer material that surrounds to form the side surface 22b is provided with expansion wing 23 and positioning groove 24. The edge of the expansion wing 23 is rounded. The standardized length of the expansion wing 23 can improve the consistency of sewing operations by different workers. Moreover, through the extension of the expansion wing 23, the size of the sewing opening at the top of the inner liner 22 is larger than the size of the opening connecting to the bottom plate 21 at the bottom, which makes it easier to open the top opening for sewing. The positioning groove 24 is V-shaped or U-shaped. The positioning groove 24 makes it easier for workers to quickly identify the alignment position and improve the positioning accuracy.

[0035] Production and assembly process:

[0036] 1. First, fix the bottom surface 22a of the inner liner 22 to the base plate 21. This can be done by sewing or other methods so that the bottom surface 22a of the inner liner 22 wraps around the base plate 21 and forms a fixed connection with it, forming an integrated structure of the inner liner 22 and the base plate 21. This step provides a stable reference for subsequent assembly and prevents the inner liner 22 from becoming loose.

[0037] 2. Place the insulation panel 3 inside the outer cover 1 and adjust its position to ensure that the insulation panel 3 fits snugly against the outer cover 1, and ensure that the insulation panel 3 is properly positioned inside the outer cover 1.

[0038] 3. Then, the bottom plate 21, which is fixedly connected to the inner liner 22, is embedded into the mounting groove 31 of the insulation panel 3. The elastic insulation pad on the inner side of the mounting groove 31 is in close contact with the bottom plate 21 to achieve stable assembly.

[0039] 4. The inner liner 22 is sewn to the outer cover 1. During sewing, the seam opening is opened using the seam flap 23. Due to the presence of the seam flap 23, the seam opening above the inner liner 22 is effectively enlarged. Compared with the traditional structure with similar upper and lower opening sizes, the seam opening can be opened more easily. The side 22b on the inner liner 22 is positioned and aligned by the positioning groove 24. The seam opening is opened by the seam flap 23, which facilitates the operation of the worker. During sewing, the position of the bottom plate 21 is positioned by the heat insulation plate 3, which can fix the inside of the inner liner 22. This allows the inner liner 22 to be pulled tight during sewing, avoiding the problem of the inner liner 22 being pulled up during sewing. This prevents the sewn inner liner 22 from being loose and makes it easier for the worker to complete the sewing connection between the perimeter wall and the outer cover 1.

[0040] 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.
