Description

Technical Field

[0001] The present application relates to the field of packaging technology, and in particular to a liner and a packaging box. Background Art

[0002] In order to prevent the display device from being damaged by collision during transportation, a box containing the display device is usually filled with a pad between the box and the display device to absorb impact energy.

[0003] In the related art, the pad is designed to be L-shaped. However, there is a large amount of space wasted when multiple L-shaped pads are stacked on top of each other, and the L-shaped pad is only suitable for machine packaging with a predetermined width, and has low versatility. Utility Model Content

[0004] The purpose of the present application is to provide a liner and a packaging box, which can improve the versatility of the liner while reducing the space waste caused by stacking multiple liner on each other.

[0005] To achieve the above-mentioned objectives, the present application provides a pad on the one hand, which includes at least a first protective segment and a second protective segment, wherein the first protective segment extends along a first direction, and the first protective segment has a first side surface and a second side surface arranged back to back with the first side surface; the second protective segment is arranged at one end of the first protective segment along the first direction, and the second protective segment moves along the second direction under the action of external force to form a folded state and an unfolded state, and the second direction intersects with the first direction, and the first side surface and the second side surface are located in the second direction; when the second protective segment is in the folded state, the second protective segment is located between the first side surface and the second side surface, and when the second protective segment is in the unfolded state, the second protective segment partially extends from between the first side surface and the second side surface.

[0006] The technical solution provided by this application allows the second protective segment to be folded when the liner is not in use, i.e., confined between the first and second side surfaces. This prevents the second protective segment from protruding from the side surfaces of the first protective segment, which would otherwise result in significant space waste between the stacked liner segments. This reduces storage space and transportation costs. When the liner is in use, the second protective segment can be extended, i.e., partially extending from between the first and second side surfaces, thereby providing support and protection. Furthermore, the second protective segment can be stretched and extended to a desired length based on actual usage requirements to accommodate packaged items of varying widths, thereby enhancing the versatility of the liner.

[0007] Optionally, the first direction is perpendicular to the second direction.

[0008] Optionally, when the second protection segment is in the expanded state, the second protection segment partially extends from the side where the first side is located.

[0009] Through the above solution, when the second protection segment is in the expanded state, the second protection segment and the first protection segment can form a V-shaped structure, or an L-shaped structure, to adapt to the packaging of the corresponding packaged item.

[0010] Optionally, a surface of the second protective segment adjacent to the second side surface is flush with the second side surface.

[0011] Through the above scheme, the supporting effect of the second protective segment and the first protective segment on the package at the angle formed by the whole can be improved, and the aesthetics of the whole formed by the second protective segment and the first protective segment on the side where the second side is located can also be improved.

[0012] Optionally, when the second protective segment is in the folded state, a surface of the second protective segment adjacent to the first side surface is flush with the first side surface.

[0013] With this solution, the second protective segment can fully utilize the space above the first protective segment to form more expandable portions of the second protective segment, allowing the second protective segment to have a longer stretchable length, thereby improving its versatility. Furthermore, the aesthetics of the entire structure formed by the second and first protective segments on the side of the first side surface can be enhanced.

[0014] Optionally, the second protective segment includes a fixed portion and a telescopic grid portion; the fixed portion is connected to the first protective segment, the telescopic grid portion is connected to one end of the fixed portion along the second direction and adjacent to the first side surface, and the telescopic direction of the telescopic grid portion is the same as the second direction.

[0015] Optionally, the fixing portion and the first protective segment are an integral structure.

[0016] With the above solution, it is only necessary to connect the telescopic grid portion and the fixing portion along the second direction and at one end adjacent to the first side surface. The fixing portion and the first protective section do not need to be assembled, thus reducing the number of assembly steps.

[0017] Optionally, the fixing portion, the telescopic grid portion and the first protective segment are an integrated structure.

[0018] Through the above solution, the connection strength between the various components of the pad can be improved, and the fixing part, the telescopic grid part and the first protective section do not need to be assembled with each other, which reduces the assembly steps and improves production efficiency.

[0019] Optionally, the first protective segment and the second protective segment are made of the same plate; a cutting seam extending along the second direction toward the second side surface is provided on the side of the plate where the first side surface is located, and an overlapping portion is left between the cutting seam and the second side surface, and the cutting seam and the overlapping portion together divide the plate into the first protective segment and the second protective segment; in the second protective segment, the portion adjacent to the overlapping portion is the fixed portion, and the portion adjacent to the cutting seam is the telescopic mesh portion, and a cutting seam is provided on the telescopic mesh portion, and the cutting seam passes through the telescopic mesh portion along the first direction, so that the telescopic mesh portion has a stretchable and expandable characteristic.

[0020] Through the above solution, the forming method of the liner can be simplified and the production cost can be reduced.

[0021] Optionally, when the second protection segment is in the expanded state, the second protection segment partially extends from both the side where the first side is located and the side where the second side is located.

[0022] Through the above solution, when the second protection segment is in the expanded state, the second protection segment and the first protection segment can form a T-shaped structure to meet different packaging requirements.

[0023] To achieve the above-mentioned purpose, the present application further provides a packaging box on the other hand, which at least includes the above-mentioned pad. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] To protect display devices from collisions and damage during transport, boxes containing display devices often include padding between the box and the display device to absorb impact energy. Related art designs employ L-shaped padding, with one end of the pad placed on the top or bottom of the display device, and the other end placed on the front or back of the display device, thereby expanding the padding's protective coverage.

[0040] However, this L-shaped pad is fixed in shape and cannot be deformed. When multiple L-shaped pads are stacked, significant space is wasted, resulting in a large storage footprint. During transportation, fewer L-shaped pads can fit into a single box, increasing shipping costs. Furthermore, L-shaped pads are only suitable for packaging machines with a fixed width and cannot effectively package and support wider machines, making them less versatile.

[0041] To address the above technical issues, the inventors of this application devised a design in which one section of the L-shaped liner is stretchable. This allows it to be retracted when not in use, forming a long strip with the other section. This allows the two L-shaped liners to be stacked seamlessly, reducing the significant space waste caused by stacking, thereby reducing storage space and transportation costs. Furthermore, since one section of the L-shaped liner is stretchable, it can be stretched to the desired length based on actual usage requirements to accommodate packaging for machines of varying widths, thereby enhancing the versatility of the liner.

[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0043] The present application provides a pad, which is used as a packaging material for a packaged item (such as a display screen, an interactive tablet, and a smart blackboard, etc.) to provide good cushioning and support for the packaged item.

[0044] Please also see Figures 1 to 4 The liner may include at least a first protection segment 100 and a second protection segment 200. The first protection segment 100 extends in a first direction (eg Figure 2 and Figure 3 The first protective segment 100 extends in the vertical direction (as shown in FIG), and has a first side surface 110 and a second side surface 120 disposed opposite the first side surface 110. The second protective segment 200 is disposed at one end of the first protective segment 100 along the first direction. Under the action of an external force, the second protective segment 200 moves along the second direction to form a folded state and an unfolded state; in other words, the second protective segment 200 has a folded state and an unfolded state, and the folded state and unfolded state are formed when the second protective segment 200 moves along the second direction under the action of an external force. It should be noted that the above-mentioned folded state and unfolded state are both stable states. That is, after the second protective segment 200 forms a folded state or an unfolded state under the action of an external force, the second protective segment 200 can maintain the existing state without change after the external force is removed.

[0045] The first and second directions intersect, and the first side surface 110 and the second side surface 120 are located in the second direction. When the second protection segment 200 is in a folded state, the second protection segment 200 is located between the first side surface 110 and the second side surface 120. When the second protection segment 200 is in an unfolded state, the second protection segment 200 partially extends from between the first side surface 110 and the second side surface 120.

[0046] In this way, when the liner is not in use, force can be applied to fold the second protective section 200, confining it between the first side 110 and the second side 120. This prevents the second protective section 200 from protruding from the side of the first protective section 100, which would otherwise result in significant space waste between stacked liners when transporting a large number of liners. This reduces storage space and transportation costs. When the liner is in use, force can be applied to unfold the second protective section 200, partially extending it from between the first side 110 and the second side 120, thereby providing support and protection. Furthermore, the second protective section 200 can be stretched and unfolded to a desired length based on actual usage requirements to accommodate packaged items of varying widths, thereby enhancing the versatility of the liner.

[0047] The intersection of the first direction and the second direction may include a situation where the first direction and the second direction form an acute angle or an obtuse angle. Accordingly, when the second protection segment 200 is in the deployed state, the angle between the first protection segment 100 and the second protection segment 200 may be an acute angle or an obtuse angle.

[0048] The above-mentioned first direction intersects with the second direction, and the first direction and the second direction may also be perpendicular to each other. Accordingly, when the second protection segment 200 is in the deployed state, the first protection segment 100 and the second protection segment 200 are perpendicular to each other.

[0049] Please see again Figure 2 and Figure 3 In one feasible embodiment, when the second protection segment 200 is in the deployed state, a portion of the second protection segment 200 may extend only from the side where the first side 110 is located or the side where the second side 120 is located. In this way, when the second protection segment 200 is in the deployed state, the second protection segment 200 and the first protection segment 100 may form a V-shaped structure or an L-shaped structure.

[0050] For the convenience of description, the following description will be made by taking the second protection segment 200 partially extending from the side where the first side surface 110 is located as an example.

[0051] In a feasible embodiment, a side of the second protective segment 200 adjacent to the second side surface 120 is flush with the second side surface 120, thereby improving the supporting effect on the package at the angle formed by the second protective segment 200 and the first protective segment 100, and can improve the aesthetics of the whole formed by the second protective segment 200 and the first protective segment 100 on the side where the second side surface 120 is located.

[0052] Of course, the side of the second protection segment 200 adjacent to the second side surface 120 may also be staggered with respect to the second side surface 120 , that is, the side of the second protection segment 200 adjacent to the second side surface 120 is located between the second side surface 120 and the first side surface 110 .

[0053] like Figure 2 As shown, in one feasible embodiment, when the second protective segment 200 is in the folded state, the side of the second protective segment 200 adjacent to the first side surface 110 is flush with the first side surface 110. This allows the second protective segment 200 to fully utilize the space above the first protective segment 100 to form more expandable portions of the second protective segment 200, resulting in a longer stretchable length and improving the versatility of the second protective segment 200. Furthermore, the aesthetics of the overall structure formed by the second protective segment 200 and the first protective segment 100 on the side of the first side surface 110 can be enhanced.

[0054] Of course, when the second protective segment 200 is in the folded state, the side of the second protective segment 200 adjacent to the first side 110 and the first side 110 can also be staggered, that is, the side of the second protective segment 200 adjacent to the first side 110 is located between the first side 110 and the second side 120.

[0055] In practical applications, the cross-section of the first protective segment 100 can be a rectangular parallelepiped or a hexahedron of other shapes. The first protective segment 100 also has a third side surface and a fourth side surface, which are located between the first side surface 110 and the second side surface 120. The first side surface 110, the second side surface 120, the third side surface, and the fourth side surface collectively constitute the outer wall surface of the first protective segment 100. When the second protective segment 200 is in the folded state, the outer wall surface of the first protective segment 100 is flush with the outer wall surface of the second protective segment 200.

[0056] Regarding the specific structure of the second protection segment 200, in one achievable embodiment, as shown in FIG. Figure 4 and Figure 5 As shown, the second protective segment 200 may include a fixed portion 210 and a retractable mesh portion 220. The fixed portion 210 is connected to the first protective segment 100, and the retractable mesh portion 220 is connected to an end of the fixed portion 210 along the second direction and adjacent to the first side surface 110. The retractable mesh portion 220 retracts in the same direction as the second direction. Thus, by stretching the retractable mesh portion 220, the second protective segment 200 can be partially extended from the first side surface 110, and by compressing the retractable mesh portion 220, the second protective segment 200 can be positioned between the first side surface 110 and the second side surface 120.

[0057] The specific structure of the telescopic mesh portion 220 may refer to the existing pearl cotton (EPE) telescopic mesh plate, which will not be described in detail here.

[0058] Furthermore, the fixing portion 210 can be integrally formed with the first protective segment 100. In practical applications, the telescopic mesh portion 220 only needs to be connected to one end of the fixing portion 210 along the second direction and adjacent to the first side surface 110. The fixing portion 210 and the first protective segment 100 do not need to be assembled, thus reducing the number of assembly steps.

[0059] Furthermore, the fixing portion 210, the telescopic mesh portion 220, and the first protective section 100 are integrally formed. This improves the connection strength between the various components of the liner, and eliminates the need for separate assembly of the fixing portion 210, the telescopic mesh portion 220, and the first protective section 100, thus reducing assembly steps and improving production efficiency.

[0060] Regarding the molding method of the fixed part 210, the telescopic grid part 220 and the first protective segment 100 as an integrated structure, in a feasible embodiment, the first protective segment 100 and the second protective segment 200 are processed from the same plate, and the plate is made of a material with cushioning and supporting properties. The plate can be a pearl cotton (EPE) board, polystyrene foam (EPS) board, polyurethane foam (PU) board and EVA foam board, etc.

[0061] Specifically, a cutout slit 300 extending along the second direction toward the second side 120 is provided on the side of the panel located on the first side 110. The cutout slit 300 does not completely sever the panel, leaving an overlapping portion 400 between the cutout slit 300 and the second side 120. The cutout slit 300 and the overlapping portion 400 together divide the panel into a first protective section 100 and a second protective section 200. In the second protective section 200, the portion connected to the overlapping portion 400 is a fixed portion 210, and the portion adjacent to the cutout slit 300 is a telescopic mesh portion 220. The telescopic mesh portion 220 is provided with a cutout slit 221 that penetrates the telescopic mesh portion 220 along the first direction, thereby enabling the telescopic mesh portion 220 to be stretchable and expandable, thereby achieving the aforementioned function of extending from and retracting to the first side 110.

[0062] When the second protection section 200 is in the unfolded state and the liner is L-shaped, the present application provides a feasible packaging structure. Figure 6 As shown in the cross-sectional diagram of the packaging structure, the liner 1000 is arranged at the four corners of the package 2000, and the first protective section 100 and the second protective section 200 of the liner 1000 are overlapped on the adjacent two sides of the corresponding angles.

[0063] like Figure 7 and Figure 8As shown, in one feasible embodiment, when the second protection segment 200 is in the deployed state, a portion of the second protection segment 200 can simultaneously extend from the side where the first side 110 is located or the side where the second side 120 is located. In this way, when the second protection segment 200 is in the deployed state, the second protection segment 200 and the first protection segment 100 can form a T-shaped structure.

[0064] Specifically, the second protective section 200 may include a fixed portion 210 and two telescopic grid portions 220 , the two telescopic grid portions 220 are respectively connected to both ends of the fixed portion 210 along the second direction, and the telescopic direction of the two telescopic grid portions 220 is the same as the second direction.

[0065] When the second protection section 200 is in the unfolded state and the liner is T-shaped, the present application provides a feasible packaging structure. Figure 9 In the cross-sectional schematic diagram of the packaging structure shown, the first protective section 100 of the liner 1000 is located between two items to be packaged 2000 , and the second protective section 200 is overlapped on the top or bottom of the two items to be packaged 2000 .

[0066] Based on the same inventive concept, the present application also provides a packaging box, which may include the above-mentioned pad 1000. The specific structure of the pad 1000 can be referred to the detailed content in the above embodiment, and will not be repeated here.
