This upward-facing handle can affect the sealing efficiency when attaching the sealing edge from one side of the bag to the other, thus impacting the packing efficiency of the tote bag. Utility Model Content

[0003] In view of this, this application provides a tote bag that at least solves the problem of low packing efficiency for tote bags. This application also provides a refrigerated express storage box including the aforementioned tote bag.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0024] This application provides a tote bag that at least solves the problem of low packing efficiency for tote bags. This application also provides a refrigerated express storage box including the aforementioned tote bag.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] like Figure 1 and Figure 2 As shown in the figure, this application provides a tote bag for use in the packaging and logistics field. The tote bag mainly includes a bag body 1 and handles 2. The bag body 1 has an open end 11 for placing the item to be transported into the tote bag. A sealing protrusion 3 protruding from the open end 11 is provided on the first side bag surface 12 of the bag body 1. An adhesive layer is provided on the sealing protrusion 3, which can be bonded to the second side bag surface 13 on the opposite side of the first side bag surface 12 to seal the open end 11. This achieves the sealing of the tote bag and prevents the item to be transported from being moved out of the tote bag. This also improves the cooling effect of the cooling medium on the item to be transported after the item to be transported and the cooling medium are placed in the tote bag. Multiple handles 2 are provided and are respectively provided on the first side bag surface 12 and the second side bag surface 13 of the bag body 1. When the express delivery arrives, the customer can conveniently take out the tote bag by holding the handles 2 provided on the first side bag surface 12 and the second side bag surface 13.

[0027] Each handle 2 is provided with a folding portion 21, which allows a portion of the handle 2 to bend away from the opening end 11 under the action of force. Specifically, during the packing process of the tote bag, firstly, the operator applies force to the handle 2 of the tote bag to bend the handle 2 at the folding portion 21, causing a portion of the handle 2 to bend away from the opening end 11; then, the package to be delivered and the cooling medium are placed into the tote bag; next, the sealing protrusion 3 provided on the first side surface 12 of the bag body 1 is attached to the second side surface to seal the opening end 11 of the bag body 1; finally, the packed tote bag is placed into the box to complete the packing.

[0028] It should be noted that the foldable portion 21 refers to a part of the handle 2 that is prone to bending, so that the handle 2 will bend under the action of force. The structure of the foldable portion 21 is not limited here. For example, the foldable portion 21 can be an area of ​​thinner material on the handle 2, which is more prone to bending when the handle 2 is subjected to force; the foldable portion 21 can also be an area of ​​softer material on the handle 2, meaning that the material of the foldable portion 21 is less flexible than the rest of the handle 2, so that this part is also prone to bending when the handle 2 is subjected to force; the foldable portion 21 can also be a part of the handle 2 with a bending line, meaning that this part will also bend when the handle 2 is subjected to force; the foldable portion 21 can also be a crease formed by the operator applying external force, which can also cause a part of the handle 2 to bend away from the opening end 11.

[0029] It should also be noted that the foldable part 21 causes the handle 2 to bend in a direction away from the opening end 11 under the action of force. The force can be an external force applied to the handle 2 by the operator or the weight of the handle 2 itself.

[0030] The tote bag with the above structure includes a bag body 1 and a handle 2 provided on the bag body 1. A foldable portion 21 is provided on the handle 2, and under the action of force, the foldable portion 21 causes a portion of the handle 2 to bend away from the opening end 11. This design allows the handle 2 to bend from the location of the foldable portion 21 before the operator seals the tote bag with the sealing edge 3. This causes a portion of the handle 2 to bend away from the opening end 11, thus reducing or even eliminating the obstruction of the sealing edge 3 by the handle 2 when the operator seals the opening end 11 with the sealing edge 3, thereby improving the packing efficiency of the tote bag.

[0031] In some embodiments, please refer to Figure 1 and Figure 2When tote bags are used in cold chain transportation, since the items to be transported inside are frozen goods, a cooling medium needs to be added inside the tote bag. Tote bags are usually made of non-woven fabric, and due to thermal expansion and contraction, the adhesive layer of the sealing edge 3 will shrink in low-temperature environments, causing the sealing edge 3 to spring open during transportation, thus affecting the quality of the items being transported. The dimension of the sealing edge 3 protruding from the opening end 11 is L, where L satisfies: 37mm ≤ L ≤ 43mm. Ensuring that the dimension of the sealing edge 3 meets the above range is crucial. On the one hand, it prevents the sealing edge 3 from being too small, thus preventing it from springing open during transportation and affecting the quality of the items being transported. On the other hand, it prevents the sealing edge 3 from being too large, thus preventing interference with the handle 2 when it is adhered to the second side of the bag body 1, and thus affecting the sealing efficiency of the sealing edge 3 to the opening end 11. This configuration can improve the sealing stability of the opening end 11, while also improving the sealing efficiency of the sealing protrusion 3 on the opening end 11.

[0032] For example, the dimensions of the sealing protrusion 3 can be: 37mm, 38mm, 39mm, 40mm, 41mm, 42mm, 43mm, etc.

[0033] In some embodiments, please refer to Figure 1 and Figure 2 During the process of sealing the opening end 11 through the sealing protrusion 3, the sealing protrusion 3 is folded towards the second side bag surface 13 to adhere the adhesive layer on the sealing protrusion 3 to the second side bag surface 13, thereby achieving the sealing of the opening end 11 of the bag body 1 by the sealing protrusion 3. Therefore, during this process, the handle 2 provided on the second side bag surface 13 will obstruct the sealing of the sealing protrusion 3. Thus, two foldable parts 21 are provided on the handle 2 provided on the second side bag surface 13. The handle 2 includes two connecting parts 22 connected to the second side bag surface 13 and a handle part 23 provided between the two connecting parts 22, and the two foldable parts 21 are respectively provided on the two connecting parts 22. With this configuration, before attaching the sealing protrusion 3 to the second side bag surface 13, the handle 2 on the second side bag surface 13 is applied in a direction away from the opening end 11. The handle 2 will bend at the foldable part 21 position on both connecting parts 22, so that the handle 2 handle part 23 moves away from the opening end 11. In this way, when attaching the sealing protrusion 3 to the second side bag surface 13, the influence of the handle 2 on the sealing protrusion 3 is further reduced, and the efficiency of the sealing protrusion 3 in sealing the opening end 11 of the bag body 1 is further improved.

[0034] Furthermore, since the handle 2 on the first side bag surface 12 also affects the sealing efficiency of the sealing protrusion 3, two easy-folding parts 21 can be provided on the handle 2 on the first side bag surface 12. The handle 2 includes two connecting parts 22 connected to the second side bag surface 13 and a handle part 23 provided between the two connecting parts 22, and the two easy-folding parts 21 are respectively provided on the two connecting parts 22. This arrangement can further improve the sealing efficiency of the sealing protrusion 3 in sealing the opening end 11 of the bag body 1.

[0035] In some embodiments, please refer to Figure 1 and Figure 2 The handle 2 is made of non-woven fabric. The sealing edge 3 includes a double-sided area 32 with two layers of non-woven fabric and a single-sided area 31 with a single layer of non-woven fabric. The double-sided area 32 is located on the side of the single-sided area 31 away from the bag body 1. Non-woven fabric has advantages such as being lightweight and soft, antibacterial and stain-resistant, flame-retardant, environmentally friendly, and low-cost and easy to process. Here, by setting the double-sided area 32 with double-sided non-woven fabric, the structural strength of the sealing edge 3 can be improved, thereby improving the structural strength of the sealing edge 3 in sealing the opening end 11 of the bag body 1, so as to prevent the sealing edge 3 from popping open due to thermal expansion and contraction during transportation, thus avoiding affecting the quality of the items to be transported.

[0036] Furthermore, based on the above embodiment, the double-sided area 32 is provided with an adhesive layer that can adhere to the second side bag surface 13. Since the double-sided area 32 is located on the side away from the bag body 1, by providing the adhesive layer on the second side bag surface 13, the adhesion stability between the adhesive layer and the double-sided area 32 can be improved, and the adhesion and sealing performance between the sealing protrusion 3 and the bag body 1 can be improved, thereby further enhancing the sealing stability of the sealing protrusion 3 to the opening end 11.

[0037] In some embodiments, please refer to Figure 1 and Figure 2 In the protruding direction of the sealing protrusion 3, the size of the double-sided area 32 is L1, and the size of the single-sided area 31 is L2, where L1 and L2 satisfy: L1≥3*L2. Here, by satisfying the above range for the sizes of the double-sided area 32 and the single-sided area 31, the proportion of the double-sided area 32 in the sealing protrusion 3 can be increased. Furthermore, since the adhesive layer is set on the double-sided area 32, the size of the adhesive layer can also be increased. Increasing the size of the adhesive layer can also improve the bonding stability between the sealing protrusion 3 and the bag body 1, thereby improving the sealing stability of the sealing protrusion 3 to the opening end 11 of the bag body 1.

[0038] It should be noted that the protruding direction of the sealing flange 3 is... Figure 2 The direction indicated by the middle arrow X.

[0039] For example, in the protruding direction of the sealing protrusion 3, the size L1 of the double-sided area 32 can be: 3*L2, 3.2*L2, 3.5*L2, 4*L2, 5*L2, etc.

[0040] In some embodiments, please refer to Figure 1 and Figure 2 In the direction where the sealing edge 3 protrudes from the opening end 11, the distance between the connection point of the handle 2 and the bag body 1 and the top of the bag body 1 is H1, and the size of the bag body 1 is H, where H1 and H satisfy the following relationship: 0.3≤H1:H≤0.4. This ensures that the ratio between the distance between the connection point of the handle 2 and the top of the bag body 1 and the size of the bag body 1 meets the above relationship. On the one hand, it avoids the ratio being too small, preventing the handle 2 from interfering with the sealing edge 3 when it is pasted onto the second side of the bag surface 13; on the other hand, it avoids the ratio being too large, preventing the handle 2 from being too long and causing inconvenience for the operator when carrying the bag. This design improves the sealing efficiency of the sealing edge 3 on the bag body 1, enhances the sealing effect, and improves the convenience for the operator when carrying the bag.

[0041] For example, the ratio between H1 and H can be: 0.3, 0.31, 0.32, 0.35, 0.38, 0.39, 0.4, etc.

[0042] In some embodiments, please refer to Figure 1 and Figure 2 In the direction where the sealing edge 3 protrudes from the opening end 11, the size of the handle 2 is H2, and the size of the bag body 1 is H, wherein H2 and H satisfy the following ratio: 0.45 ≤ H2 : H ≤ 0.5. This ensures that the ratio between the distance between the connection point of the handle 2 and the top of the bag body 1 and the size of the bag body 1 meets the above range. On the one hand, this avoids the ratio being too small, preventing the handle 2 from interfering with the sealing edge 3 when it is pasted onto the second side of the bag surface 13; on the other hand, it avoids the ratio being too large, preventing the handle 2 from interfering with the bag body 1 when the operator lifts it. This design improves the sealing efficiency of the sealing edge 3 on the bag body 1, enhances the sealing effect, and improves the convenience for the operator when lifting the bag.

[0043] For example, the ratio between H2 and H can be: 0.45, 0.46, 0.47, 0.48, 0.49, 0.5, etc.

[0044] In some embodiments, please refer to Figure 1 and Figure 2The tote bag is made of non-woven fabric, which consists of a color-printed coating layer, a non-woven fabric layer, and an aluminum foil coating layer, arranged sequentially. This layered structure enhances the structural strength and stability of the tote bag. Furthermore, the mass ratio of the color-printed coating layer, the non-woven fabric layer, and the aluminum foil coating layer is 5:9:5. This configuration improves the tote bag's strength while maintaining its lightweight nature, and also enhances its insulation properties, thus improving the cooling effect on the items to be transported inside.

[0045] This application also provides a refrigerated express storage box including a box body and a carrying bag. The items to be transported and the cooling medium are placed inside the carrying bag, which is placed inside the box body. It should be noted that the box body is usually an EPP reusable insulated box. When the items to be transported are delivered via refrigerated express, the courier delivers the reusable insulated box containing the carrying bag to the customer, then hands over the items to be transported inside the carrying bag to the customer, and then collects the reusable insulated box. Since the carrying bag also contains cooling medium, when the customer takes the carrying bag back to use the items to be transported, the cooling medium can continue to cool the items to be transported, thus improving the cooling effect on the items to be transported inside the carrying bag.

[0046] It should be noted that the cooling medium inside the bag can be a phase change refrigerant ice pack, ice box, ice block, etc.

[0047] The aforementioned refrigerated delivery box includes a box body and a carrying bag. The carrying bag includes a bag body 1 and a handle 2 disposed on the bag body 1. A foldable portion 21 is provided on the handle 2, and the foldable portion 21 bends a portion of the handle 2 away from the opening end 11 under the action of force. With this configuration, before the operator seals the carrying bag by sealing the opening end 11 with the sealing protrusion 3, force is applied to the handle 2 to bend it from the location of the foldable portion 21, causing a portion of the handle 2 to bend away from the opening end 11. This reduces or even eliminates the obstruction of the sealing protrusion 3 by the handle 2 when the operator seals the opening end 11 of the carrying bag with the sealing protrusion 3, thereby improving the packing efficiency of the carrying bag.
