Description

Technical Field

[0001] This application relates to the field of product packaging, and more particularly to a paper inner liner block for battery packaging. Background Technology

[0002] As the battery industry continues to develop, the requirements for battery stability during transportation are becoming increasingly stringent. Good packaging not only ensures that batteries do not shake or get damaged during transport, but also improves the safety of the entire transportation and storage process.

[0003] In the shipping packaging of batteries after production, the traditional practice is to install an inner lining structure inside the box to prevent the batteries from shifting within the packaging. A common method is to place multiple pads to support the batteries; these pads are mostly made of plastic or foam. However, with increasingly stringent environmental regulations, paper pads are beginning to be used as an alternative. Generally, paper pads are made of corrugated cardboard folded, and their folding shape is determined based on factors such as the product shape and the available space within the packaging box.

[0004] However, paper pads made of corrugated cardboard have a springy texture after being folded due to the structure of the corrugated cardboard itself, which makes them easy to unfold on their own and inconvenient to use. Utility Model Content

[0005] This application provides a paper inner liner block for battery packaging, which is folded from cardboard and has high stability after folding, making it difficult to unfold on its own. It can replace pads made of plastic, foam plastic, and other materials, contributing to energy conservation and environmental protection. The technical solution adopted is as follows: A paper inner liner for battery packaging includes a folding structure; the folding structure includes a first fold, a second fold, a third fold, a fourth fold, and a fifth fold arranged sequentially. The first folding part and the second folding part are fixedly connected; The second fold and the third fold are separately provided, and a first connecting member is provided between them, and the second fold and the third fold are connected by the first connecting member; The first folding part has a first slot on the side opposite to the second folding part, and the first slot is used to cooperate with the first connector. The fourth fold is fixedly connected to the third fold, and the fifth fold is fixedly connected to the fourth fold; The width of the fourth fold corresponds to the sum of the thicknesses of the first, second, and third folds.

[0006] By adopting the above technical solution, since the second and third folding parts are separately arranged and connected by the first connector, the elastic force of the second and third folding parts after folding can be effectively reduced. Furthermore, the first folding part can be fixed by the engagement of the first connector with the first bayonet, thereby reducing the elastic force between the first and second folding parts. The fourth folding part also reduces the elastic recovery force of the fifth folding part at the fold after folding. The inner lining block can be fixed simply by gluing the fifth and second folding parts together, and it has high stability and is not easily unfolded.

[0007] Preferably, the edges of the second fold and the third fold abut each other; a notch is provided at the opposite edges of the second fold and the third fold, and the first connector is disposed in the notch; the length of the first connector corresponds to the sum of the thicknesses of the first fold, the second fold, and the third fold.

[0008] Preferably, multiple first connectors are provided; multiple first bayonets are provided accordingly.

[0009] Preferably, the width of the bayonet is less than or equal to the width of the first connector.

[0010] Preferably, the first fold and the second fold are integrally formed; the third fold, the third fold and the fifth fold are integrally formed.

[0011] Preferably, the fifth folding portion is provided with a plug-in portion, and the first folding portion is provided with a second slot corresponding to the plug-in portion.

[0012] Preferably, multiple folding structures are provided, and adjacent folding structures are connected by a second connector.

[0013] Preferably, the second connector is integrally formed with the second folding portion.

[0014] Preferably, the length of the second connector corresponds to the thickness of the single folded structure in the folded state.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. By separately setting the second and third folding parts, cooperating with the first connector and the first bayonet, and setting the fourth folding part, the elastic recovery force of the inner lining block after folding can be effectively reduced, so that the inner lining block is not easy to unfold on its own, has high stability, and is easy to use; 2. By setting a second bayonet and a plug-in part, the inner lining block can be self-fixed without glue, which has high stability; 3. Different numbers of folding mechanisms can be selected to freely form L-shaped, triangular, or square inner lining blocks. The inner lining blocks have high integrity, strong stability, and high ease of use. Attached Figure Description

[0018] The following is in conjunction with the appendix Figures 1-11 This application will be described in further detail.

[0019] Example 1 The paper inner liner block for battery packaging provided in this application embodiment refers to... Figure 1The inner lining block includes a folding structure, which can be one or multiple. Each folding structure includes a first folding part 1, a second folding part 2, a third folding part 3, a fourth folding part 4, and a fifth folding part 5 arranged sequentially. The first folding part 1 and the second folding part 2 are fixedly connected. The second folding part 2 and the third folding part 3 are separate and connected by a first connecting member 6. The third folding part 3 and the fourth folding part 4 are fixedly connected, and the fifth folding part 5 is fixedly connected to the fourth folding part 4.

[0020] In this embodiment, the folding structure can be cut from a single sheet of corrugated cardboard. The first fold 1 and the second fold 2 are integrally formed, as are the third fold 3, the fourth fold 4, and the fifth fold 5. Furthermore, one end of the first connector 6 is integrally formed with the second fold 2, and the other end is integrally formed with the third fold 3. A cutting slit 11 is punched between the second fold 2 and the third fold 3 to separate them, and the second fold 2 and the third fold 3 are connected only by the first connector 6.

[0021] The following describes the construction of the folded structure in its unfolded state: Reference Figure 1 Furthermore, the first folding part 1 has a first latch 7 on the side facing away from the second folding part 2 for engaging with the first connecting member 6. The width of the first latch 7 is equal to the width of the first connecting member 6, or the width of the first latch 7 is slightly smaller than the width of the first connecting member 6. For example, if the width of the first latch 7 is 40mm, then the width of the first connecting member 6 can be set to 38mm. When the folding structure is folded, the first connecting member 6 can be inserted into the first latch 7, which can restrict the unfolding of the folding structure and enhance the overall stability. The number of first connecting members 6 can be one, two, or more, and the specific number is determined according to actual needs.

[0022] Furthermore, notches 8 are provided at the opposite edges of the second fold 2 and the third fold 3, and both ends of the first connector 6 are located within the notches 8. The notches 8 can be rectangular in shape. The second fold 2, the first connector 6, the third fold 3, and the corresponding notches 8 are all cut from a single sheet of corrugated cardboard to ensure the integrity of the folding structure.

[0023] The length of the first connector 6 is equal to or slightly larger than the sum of the thicknesses of the first folding part 1, the second folding part 2, and the third folding part 3. For example, if the thicknesses of the first folding part 1, the second folding part 2, and the third folding part 3 are all 5mm, and the sum of their thicknesses is 15mm, then the length of the first connector 6 can be set to 15mm or more.

[0024] Furthermore, the widths of the first fold 1, the second fold 2, the third fold 3, and the fifth fold 5 are the same. The width of the fourth fold 4 is equal to or slightly larger than the sum of the thicknesses of the first fold 1, the second fold 2, and the third fold 3. For example, if the thicknesses of the first fold 1, the second fold 2, and the third fold 3 are all 5mm, and their sum is 15mm, then the length of the fourth fold 4 can be set to be 15mm or more.

[0025] The following explains the steps for preventing the folding structure from folding: Reference Figure 2 First, fold the first fold 1 and the second fold 2 in half; Reference Figure 3 The second step is to fold the second folding part 2 and the first folding part 1 together toward the third folding part 3, and to position the first folding part 1 between the second folding part 2 and the third folding part 3; at the same time, to engage the first bayonet 7 with the first connector 6. Reference Figure 4 and Figure 5 The third step is to fold the fourth fold 4 so that the fifth fold 5 moves to the second fold 2 and folds the fifth fold 5 until it fits snugly against the second fold 2.

[0026] Reference Figure 6 The fifth fold 5 and the second fold 2 can be glued together.

[0027] Reference Figure 7 Furthermore, when multiple folding structures are provided, adjacent folding structures are connected by a second connector 12. The second connector 12 can be integrally provided with the second folding part 2, that is, multiple folding structures and the second connector 12 are all cut from a single sheet of corrugated cardboard, which makes manufacturing more convenient and ensures the reliability of the connection. The length of the second connector 12 is the same as or slightly larger than the thickness of a single folding structure in the folded state. For example, if the thickness of the folding structure in the folded state is 40mm, then the length of the second connector 12 can be 40mm or 42mm. Thus, two adjacent folding structures can be folded relative to each other into an L-shape. The number of folding structures can be set to two, thereby forming an L-shaped pad structure; the number of folding structures can also be set to four, thereby forming a square pad.

[0028] The implementation principle of this embodiment is as follows: The paper inner liner for battery packaging in this embodiment enhances the stability of the folded structure through the reasonable arrangement of each fold and the cooperation of the connectors and latches, making it less prone to unfolding on its own. At the same time, using paper material instead of plastic or foam padding meets the requirements of energy conservation and environmental protection. This design not only solves the problem of existing paper pads easily unfolding but also meets the industry's demand for green and environmentally friendly packaging, demonstrating good practicality and innovation.

[0029] Example 2 The difference between this embodiment and Embodiment 1 is that, referring to... Figure 8 A connector 9 is added to the fifth folding section 5. Specifically, the connector 9 is located on the side of the fifth folding section 5 facing away from the fourth folding section 4. Simultaneously, a second latch 10 corresponding to the connector 9 is provided on the first folding section 1. (See reference...) Figure 9 , Figure 10 and Figure 11 When the folding structure is in the folded state, the first folding part 1 is located between the second folding part 2 and the third folding part 3. That is, the second folding part 2 and the third folding part 3 are located on both sides of the second bayonet 10, thus forming a slot. The insertion part 9 can be inserted into the slot, and the fifth folding part 5 can be fixed without glue, so that the folding structure forms a stable whole and is not easy to unfold on its own.

[0030] Similarly, the width of the insertion part 9 is equal to or slightly larger than the width of the second bayonet 10, so as to facilitate a tight fit between the insertion part 9 and the second bayonet 10, making the structure more stable.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
