[0037] This application provides a parcel box that solves the problems of cumbersome and inefficient assembly, as well as poor structural stability.

[0038] 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.

[0039] like Figures 1 to 8As shown, this application embodiment provides a courier box, which is typically used to transport items requiring insulation, i.e., for cold chain transportation. The courier box includes a box body 1 and a lid 2 that fastens to the opening of the box body 1. The box body 1 mainly includes an outer box 11, an inner box 12, and a heat insulation layer 13. The inner box 12 and the heat insulation layer 13 are both disposed in the inner cavity of the outer box 11, and the heat insulation layer 13 is located between the outer box 11 and the inner box 12. Generally, the outer box 11 and the inner box 12 are both cuboid structures with an opening at the same end. The heat insulation layer 13 also has multiple walls, and the multiple walls of the heat insulation layer 13 are respectively located between the corresponding walls of the outer box 11 and the inner box 12. Furthermore, the outer casing 11 and the inner casing 12 are connected to clamp and fix the heat insulation layer 13. Specifically, before the outer casing 11 and the inner casing 12 are connected, the heat insulation layer 13 is placed between the outer casing 11 and the inner casing 12. The heat insulation layer 13 is clamped and fixed by connecting the outer casing 11 and the inner casing 12, thus facilitating the assembly of the outer casing 11, the heat insulation layer 13 and the inner casing 12.

[0040] It should be noted that the connection method between the outer box 11 and the inner box 12 is not limited here. For example, the outer box 11 and the inner box 12 can be connected by a fixed connection method, such as: adhesive, heat fusion, etc.; for example, the outer box 11 and the inner box 12 can also be connected by a detachable connection method, such as: threaded connection, snap connection, elastic interference fit, magnetic connection, etc.

[0041] The aforementioned express delivery box includes an outer box 11, an inner box 12, and a heat insulation layer 13. Both the inner box 12 and the heat insulation layer 13 are located within the inner cavity of the outer box 11, with the heat insulation layer 13 situated between the outer box 11 and the inner box 12. The connection between the outer box 11 and the inner box 12 secures and clamps the heat insulation layer 13. This configuration allows for the fixation of the heat insulation layer 13 located between the outer box 11 and the inner box 12, simultaneously achieving the connection between the outer box 11 and the inner box 12. This improves the assembly efficiency of the outer box 11, inner box 12, and heat insulation layer 13, and also enhances the structural stability of the assembled express delivery box.

[0042] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 6The outer box 11 and the inner box 12 each have a groove 111 and a protrusion 121, respectively. The protrusion 121 engages with the groove 111 to connect the inner box 12 and the outer box 11. In other words, the outer box 11 and the inner box 12 are connected by a detachable connection. This design allows for faster assembly of the outer box 11 and the inner box 12, thus improving the assembly efficiency of the express box. Furthermore, during long-term use and transportation, if any of the outer box 11, the insulation layer 13, or the inner box 12 is damaged, the detachable connection between the outer box 11 and the inner box 12 allows for easy disconnection and replacement of the damaged component. This improves the ease of replacement of the outer box 11, the insulation layer 13, and the inner box 12, thereby extending the lifespan of the express box.

[0043] For example, this embodiment includes the following specific implementation: a groove 111 is provided in the outer box 11, and a protrusion 121 that engages with the groove 111 is provided in the inner box 12; a groove 111 is provided in the inner box 12, and a protrusion 121 that engages with the groove 111 is provided in the outer box 11; a groove 111 is provided in the outer box 11, and a protrusion 121 that engages with the groove 111 is provided in the inner box 12, and a groove 111 is also provided in the inner box 12, and a protrusion 121 that engages with the groove 111 is also provided in the outer box 11.

[0044] In some embodiments, please refer to Figures 2 to 6 The outer box 11 includes a bottom wall 112 facing away from the opening and a side wall 113 arranged circumferentially. A groove 111 is provided on the end face 115 of the side wall 113 that forms the opening. The inner box 12 has a pressing part 122 that presses against the end face 115, and a protrusion 121 is provided on the pressing part 122. That is, the groove 111 of the outer box 11 and the protrusion 121 of the inner box 12 are engaged at the position where the box body 1 forms the opening. Normally, the heat insulation layer 13 is provided between all the walls of the outer box 11 and all the corresponding walls of the inner box 12 to improve the heat insulation effect of the express box. In this embodiment, through the above arrangement, the groove 111 and protrusion 121 structure that realize the detachable connection between the outer box 11 and the inner box 12 will not affect the arrangement of the heat insulation layer 13, which can improve the overall arrangement of the heat insulation layer 13, thereby improving the overall heat insulation performance of the express box.

[0045] In addition, the groove 111 can also be provided at other positions on the side wall 113 of the outer box 11, or the groove 111 can also be provided on the bottom wall 112 of the outer box 11; the corresponding protrusion 121 is provided at the corresponding position of the inner box 12 that can engage with the groove 111.

[0046] In some embodiments, please refer to Figure 6The end face 115 has a limiting groove 114 to accommodate the pressing part 122, so that the pressing part 122 is flush with the end face 115. That is, after the pressing part 122 is installed into the limiting groove 114, the end face 115 of the pressing part 122 away from the bottom of the limiting groove 114 is flush with the opening of the limiting groove 114. In other words, after the outer box 11 and the inner box 12 are installed together by the protrusion 121 and the groove 111, the end face 115 of the box body 1 that forms the opening is a flush surface. With this setting, by ensuring that the pressing part 122 and the end face 115 are flush, when the cover 2 is subsequently installed on the box body 1 to seal the express box, the sealing between the cover 2 and the box body 1 is improved, the sealing of the contents of the express box is improved, and thus the heat preservation performance of the express box is improved.

[0047] In some embodiments, please refer to Figure 2 and Figure 3 Multiple grooves 111 and protrusions 121 are provided in a one-to-one configuration. By providing multiple corresponding grooves 111 and protrusions 121, the stability of the connection between the outer box 11 and the inner box 12 can be improved, thereby enhancing the overall structural strength of the express box. Furthermore, the grooves 111 are respectively provided on different side walls 113 of the outer box 11, and the grooves 111 on the same side wall 113 are equally spaced. Correspondingly, the protrusions 121 are respectively provided on different sides of the outer box 11, and the protrusions 121 on the same side are equally spaced. This configuration improves the connection stability of different local areas on different walls of the outer box 11 and the inner box 12, making the connection between the outer box 11 and the inner box 12 more uniform, further enhancing the stability of the connection between the outer box 11 and the inner box 12, as well as improving the stability of the insulation layer 13, thereby enhancing the overall structural stability of the express box.

[0048] In some embodiments, please refer to 5. The protrusion 121 includes a connecting portion 1211 and a snap-fit ​​portion 1212. One end of the connecting portion 1211 is connected to the inner box 12, and the snap-fit ​​portion 1212 is connected to the other end of the connecting portion 1211. The outer diameter of the snap-fit ​​portion 1212 is larger than the outer diameter of the connecting portion 1211, so that the snap-fit ​​portion 1212 snaps into the groove 111 to achieve a detachable connection between the protrusion 121 and the groove 111. Furthermore, the limiting method between the snap-fit ​​portion 1212 and the groove 111 is not limited here. For example, the groove 111 and the snap-fit ​​portion 1212 are rigid members, and the snap-fit ​​portion 1212 and the groove 111 are connected by snap-fit. At least one of the groove 111 and the snap-fit ​​portion 1212 is an elastic structure, and the outer diameter of the snap-fit ​​portion 1212 is larger than the inner diameter of the groove 111, that is, the snap-fit ​​portion 1212 and the groove 111 are connected by interference fit.

[0049] In some embodiments, please refer to Figure 5The end of the snap-fit ​​portion 1212 away from the connecting portion 1211 is a guide structure 12121, and the cross-sectional area of ​​the guide structure 12121 decreases in the protruding direction of the protrusion 121; that is, the cross-sectional area of ​​the guide structure 12121 increases in the direction in which the protrusion 121 is inserted into the groove 111. This configuration allows the guide structure 12121 to act as a guide during the insertion of the protrusion 121 into the groove 111, thereby improving the efficiency of the protrusion 121's insertion into the groove 111, thus improving the installation efficiency of the outer box 11 and the inner box 12, and ultimately improving the assembly efficiency of the express delivery box.

[0050] It should be noted that the protrusion direction of protrusion 121 is... Figure 5 The direction indicated by the middle arrow B.

[0051] In some embodiments, please refer to Figures 3 to 5 The pressing part 122 consists of multiple pressing pieces evenly spaced along the circumference of the opening, and each pressing piece is provided with a protrusion 121. When each protrusion 121 is inserted into the corresponding groove 111, the installation of the corresponding protrusion 121 and groove 111 can be quickly achieved by observing the position of the pressing piece, thereby improving the installation efficiency of the protrusion 121 and groove 111, and thus improving the assembly efficiency of the outer box 11 and the inner box 12, thereby improving the assembly efficiency of the express box.

[0052] Typically, the connection between the box body 1 and the lid 2 of a courier box is sealed with tape to achieve a tight seal. However, when opening the courier box, a sharp object is usually used to cut the tape, which inevitably causes damage to the courier box during prolonged use. Therefore, in some embodiments, please refer to... Figure 7 and Figure 8 The pressing part 122 is a pressing ring arranged circumferentially along the opening, and the pressing ring completely covers the end face 115 of the outer box 11 that forms the opening. With this arrangement, when a sharp object is used to cut the tape, the pressing ring can prevent the sharp object from damaging the outer box 11 of the express box. Even if a sharp object is applied to the pressing ring, it will not scratch the pressing ring, thereby protecting the outer box 11 and extending the service life of the express box.

[0053] In some embodiments, the inner box 12 is an injection-molded, blow-molded, or blister-formed part. This design prevents items inside the express box from scratching the inner box 12 during use, thereby improving the structural strength and service life of the inner box 12. The outer box 11 is formed by at least one of EPP board, hollow board, XPS board, and pearl cotton board. This design improves the thermal insulation performance of the express box and makes the outer box 11 lightweight, thereby reducing the transportation difficulty during express delivery and improving express delivery efficiency. The insulation layer 13 is formed by VIP board and / or aerogel board. This design improves the thermal insulation effect of the insulation layer 13, thereby improving the thermal insulation and freshness preservation performance of the express box, and also improves the lightweight design of the express box.

[0054] It should be noted that EPP refers to polypropylene foam material, XPS refers to extruded polystyrene foam board, and VIP board refers to vacuum insulation board.

[0055] In some embodiments, the wall thickness of the outer box 11 is L1, the wall thickness of the insulation layer 13 is L2, and the wall thickness of the inner box 12 is L3, wherein L1, L2, and L3 satisfy the following conditions: 10mm≤L1≤16mm, 3mm≤L2≤7mm, and 1mm≤L3≤3mm. Ensuring that L1 is within the above range ensures the structural strength of the outer box 11 while improving the lightweight nature of the express box and enhancing its overall structural stability. Ensuring that L2 is within the above range ensures the structural strength of the insulation layer 13 while maintaining its insulation effect, thereby improving the thermal insulation performance of the express box. Ensuring that L3 is within the above range ensures the structural strength of the inner box 12 and extends its service life.

[0056] For example, L1 can be 10mm, 10.5mm, 11mm, 12mm, 13mm, 14mm, 15mm, 15.5mm, 16mm, etc.; L2 can be 3mm, 3.5mm, 4mm, 5mm, 6mm, 6.5mm, 7mm, etc.; L3 can be 1mm, 1.2mm, 1.5mm, 2mm, 2.5mm, 2.8mm, 3mm, etc.; L1+L2+L3 can be 14mm, 15mm, 18mm, 20mm, 22mm, 25mm, 26mm, etc.
