Description

Technical Field

[0001] The present invention relates to packaging box technology, in particular to a composite packaging box with a self-repairing function. Background Art

[0002] In the packaging industry, packaging boxes are important carriers during product transportation and storage, and their integrity is crucial to protecting products.

[0003] The existing packaging boxes have greater vertical support strength at the corners, but less overall support strength on the surface. Therefore, when they are accidentally bumped or affected by other external forces during use, they are prone to deformation. When the external force they are subjected to is large, they will also exert a large horizontal traction force on the corners during deformation, thereby affecting the vertical support strength at the corners of the packaging box and causing them to deform, causing the overall shape of the packaging box to change, thereby affecting the aesthetics of the packaging.

[0004] In addition, some current packaging boxes are often covered with heat shrink film on the outside, and the box lid and box body are sealed with a transparent plastic label. Although this can effectively reduce the possibility of items in the box being taken out during transportation or sales, it is still more difficult for subsequent users to open it, making the actual disassembly of the packaging box relatively mediocre and needs to be improved. Summary of the Invention

[0005] The purpose of the present invention is to provide a composite packaging box with self-repairing function to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solution: a composite packaging box with self-repairing function, comprising a box body, the box body consisting of a box body, a box cover and an inner support member, and a cavity is formed between the inner support member and the box body; The box body and the box lid are both provided with a strong support edge and a weak support surface. The box body and the box lid both include a waterproof layer, a support layer and an inner lining layer arranged in sequence from the outside to the inside. The support layer located on the weak support surface is embedded with a self-repairing elastic strip. The self-repairing elastic strip is arranged in an X shape, and the four corners of the self-repairing elastic strip correspond to the four corners of the support layer. A locking unit is provided between the box body and the box cover, and the locking unit is used to lock the box body and the box cover to prevent accidental disassembly.

[0007] Furthermore, the self-repairing elastic strip is made of aluminum alloy material and has a thickness of 0.5 mm.

[0008] Furthermore, the locking unit includes a rotating shaft rotatably connected to the surface of the box body, one end of the rotating shaft is fixedly connected to a handwheel located outside the box body, and the other end of the rotating shaft is fixedly connected to a winding wheel located inside the cavity, and guide holes are symmetrically opened at both ends of the top of the inner support member close to the handwheel side, and traction belts are fixedly connected to both sides of the inner wall of the box cover, and the traction belts on both sides pass through the guide holes away from the box cover and are wound on the winding wheel.

[0009] Furthermore, the hand wheel is arranged in a flower shape.

[0010] Furthermore, corresponding shallow grooves are provided on the surface of the hand wheel facing the box body, a same locking rod is embedded between the two shallow grooves, and a breaking groove is provided on the outer side surface of the locking rod.

[0011] Furthermore, the depth of the shallow groove is 1 / 8 of the length of the locking rod, and the locking rod is made of a brittle plastic material.

[0012] Furthermore, a fixed disk is fixedly connected to the inner wall of the cavity, an empty slot is provided inside the fixed disk, a limiting disk located inside the empty slot is fixedly connected to the outside of the rotating shaft, a number of arc protrusions are equidistantly provided on the outer side surface of the limiting disk, a plurality of guide grooves connected to the empty slot are provided inside the fixed disk, a pressure spring is fixedly connected to the inner wall of the guide groove, and a limiting rod is fixedly connected to the end of the pressure spring.

[0013] Furthermore, the limiting rod is slidably connected to the inner side surface of the guide groove, and the end of the limiting rod close to the arc protrusion is arranged in a semicircular shape, and the position and specifications of the limiting rod are adapted to the arc protrusion.

[0014] Compared with the prior art, the composite packaging box with self-repairing function provided by the present invention has the following beneficial effects: 1. This composite packaging box with self-repairing function has a self-repairing elastic strip with lightweight and high elasticity embedded inside the weak support surface of the box body, so that it can provide certain support when the box body is locally subjected to external force. In addition, the self-repairing elastic strip can also deform synchronously with the local part of the box body, so that it can drive the local part of the box body to self-repair and recover after the external force is withdrawn, making the packaging box less prone to damage.

[0015] 2. The composite packaging box with self-repair function can restrict the opening of the box lid after initial packaging through the setting of the locking unit. After the box lid is opened normally, the locking rod breaks, which can serve as a basis for determining whether the items packaged inside the box have been secretly opened during transportation, thereby increasing the safety of the items after packaging.

[0016] 3. The composite packaging box with self-repairing function can play a certain role in limiting the rotation of the box lid after closing during normal use of the packaging box through the mutual cooperation between the fixing plate, the limiting plate, the arc protrusion, the guide groove, the pressure spring and the limiting rod, so that the box lid will not be opened at will after closing, thereby ensuring its working stability.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Example 1: See also Figures 1-4 A composite packaging box with self-repairing function includes a box body 1, which is composed of a box body 101, a box cover 102 and an inner support member 103. A cavity 104 is formed between the inner support member 103 and the box body 101, and a strong support edge 2 and a weak support surface 21 are provided on the box body 101 and the box cover 102.

[0022] It should be noted that the strong support edge 2 is set at the bent corners on the box cover 102 and the box body 101. The overall support strength at this location is relatively large, and it is the main load-bearing part of the box body 1. The weak support surface 21 is the surface of the box cover 102 and the side parts of the box body 101, that is, the part between the strong support edge 2. Moreover, the larger the size of the box body 1, the lower the support strength of this part, and it is easy to deform when affected by external pressure.

[0023] The box body 101 and the box cover 102 each include a waterproof layer 3, a support layer 31, and an inner lining layer 32, which are arranged in sequence from the outside to the inside. Self-repairing elastic strips 33 are embedded in the support layer 31 located on the weak support surface 21. The self-repairing elastic strips 33 are arranged in an X shape, and the four corners of the self-repairing elastic strips 33 correspond to the four corners of the support layer 31. It should be noted that the self-repairing elastic strip 33 is made of aluminum alloy material and its thickness is 0.5 mm. The use of aluminum alloy material for the preparation of the self-repairing elastic strip 33 here is only one of the options. The material selection can be reasonably selected based on factors such as the actual production cost of the packaging box, and the material is selected based on light weight and good resilience.

[0024] During use, when the weak support surface 21 on the box body 1 is deformed by external force, the self-repairing elastic strip 33 is deformed synchronously and provides a certain support to the weak support surface 21. When the external force is removed, the self-repairing elastic strip 33 can drive the deformed weak support surface 21 to recover under the action of its rebound force, thereby effectively avoiding the box body 1 from being deformed by external force during use and requiring replacement.

[0025] Example 2: See also Figure 5-Figure 7 This embodiment provides a technical solution based on the above embodiment: a locking unit is provided between the box body 101 and the box cover 102, and the locking unit is used to lock the box body 101 and the box cover 102 to prevent accidental disassembly.

[0026] The locking unit includes a rotating shaft 4 rotatably connected to the surface of the box body 101, one end of the rotating shaft 4 is fixedly connected to a handwheel 41 located outside the box body 101, and the other end of the rotating shaft 4 is fixedly connected to a winding wheel 42 located inside the cavity 104, and guide holes 43 are symmetrically opened at both ends of the top of the inner support member 103 close to the handwheel 41. Traction belts 44 are fixedly connected to both sides of the inner wall of the box cover 102, and the traction belts 44 on both sides pass through the guide holes 43 away from the end of the box cover 102 and are wound on the winding wheel 42.

[0027] It should be noted that the handwheel 41 is arranged in a flower shape. The shape of the handwheel 41 can be set to other artistic shapes as needed, such as the shape of an animal or the shape of other aesthetically pleasing items, which can improve the aesthetics of the packaging box to a certain extent.

[0028] It should be added that corresponding shallow grooves 45 are formed on the surface of the hand wheel 41 facing the box body 101 , and a same locking rod 46 is embedded between the two shallow grooves 45 , and a breaking groove 47 is provided on the outer side of the locking rod 46 .

[0029] Moreover, the depth of the shallow groove 45 is 1 / 8 of the length of the locking rod 46. The locking rod 46 is made of a brittle plastic material, so that the locking rod 46 is relatively easy to break when needed, and it is easy to remove it from the shallow groove 45 after breaking, so that the broken locking rod 46 will not affect the aesthetics of the packaging box, and will not hinder the normal rotation of the hand wheel 41.

[0030] In the initial packaging state, the box cover 102 is in a closed state, and the traction belt 44 is wound on the winding wheel 42, so that the box cover 102 and the box body 101 are in a tightly fitted state. At this time, the locking rod 46 is also clamped on the box body 101 and between the two shallow grooves 45 on the hand wheel 41, so that the opening of the box cover 102 and the box body 101 is restricted; When the box cover 102 needs to be opened, the operator manually rotates the hand wheel 41. Under the application of a large external force, the locking rod 46 can be broken, so that the opening of the box cover 102 is no longer restricted.

[0031] Therefore, the provision of the locking rod 46 can not only effectively ensure the stability of the closure of the box cover 102, but also prevent others from secretly opening the box cover 102, thereby improving the safety of the items in the packaging box.

[0032] Example 3: See also Figure 8-Figure 9This embodiment provides a technical solution based on the above embodiment: a fixed disk 5 is fixedly connected to the inner wall of the cavity 104, an empty slot is provided inside the fixed disk 5, a limiting disk 51 located inside the empty slot is fixedly connected to the outside of the rotating shaft 4, a plurality of arc protrusions 52 are equidistantly provided on the outer side surface of the limiting disk 51, a plurality of guide grooves 53 connected to the empty slot are provided inside the fixed disk 5, a pressure spring 54 is fixedly connected to the inner wall of the guide groove 53, and a limiting rod 55 is fixedly connected to the end of the pressure spring 54.

[0033] It should be added that the limiting rod 55 is slidably connected to the inner side surface of the guide groove 53 , and the end of the limiting rod 55 close to the arc protrusion 52 is set in a semicircular shape, and the position and specifications of the limiting rod 55 are adapted to the arc protrusion 52 .

[0034] The limiting rod 55 is pushed by the pressure spring 54, and the relative rotational friction resistance between the limiting rod 55 and the arc protrusion 52 is large, which can limit the free rotation of the hand wheel 41, so that the stability of the box cover 102 when closed can be guaranteed during subsequent normal use.

[0035] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
