Technical Field

[0001] This invention relates to the field of server packaging technology, and more particularly to a cushioning package and a packaging box. Background Technology

[0002] Servers are high-value and sophisticated devices that are sensitive to impact and vibration during transportation. Therefore, the packaging of servers requires a specially designed internal cushioning structure.

[0003] The internal cushioning structure of a server includes padding, which is mainly used to protect against shocks and vibrations. Commonly used padding materials include EPE (Expandable Polyethylene).

[0004] Currently, to protect all six sides of a server, a large, one-piece padding is typically used to wrap the server. However, this internal cushioning packaging structure requires a large amount of padding per server, resulting in higher server packaging costs. Summary of the Invention

[0005] This invention provides a cushioning package and a packaging box, which aims to at least solve the technical problem of excessive padding used in the packaging of a single server in the prior art.

[0006] In a first aspect of the present invention, a cushioning package is provided, comprising a flexible film and a plurality of padding blocks connected to the flexible film, the flexible film having an inner surface and an outer surface, the padding blocks protruding from the outer surface of the flexible film.

[0007] The cushioning package has a packaged state and a stored state. When the cushioning package is in the packaged state, the flexible film wraps the packaged product and the inner surface of the flexible film is in contact with the packaged product. When the cushioning package is in the stored state, the flexible film is rolled into a cylindrical shape.

[0008] Optionally, the flexible film includes an outer film, on which a plurality of through-holes are provided. The number of through-holes is greater than or equal to the number of pad blocks. Each pad block includes a pad body and a base connected to the pad body. The pad body passes through the through-holes. The cross-sectional area of ​​the base is greater than the cross-sectional area of ​​the through-holes. The base is located on the side of the outer film closer to the inner surface.

[0009] Optionally, the flexible film further includes an inner film stacked with the outer film, and the base is located between the outer film and the inner film.

[0010] Optionally, the outer film also has a plurality of annular connecting portions, which are located on the outside of the plurality of limiting holes, and each annular connecting portion is connected to the inner film by hot pressing.

[0011] Optionally, the pad body has a first end away from the base and a second end close to the base. The cross-sectional area of ​​the second end of the pad body is equal to the cross-sectional area of ​​the limiting hole. The cross-sectional area of ​​the pad body gradually decreases from the second end of the pad body to the first end of the pad body.

[0012] Optionally, the outer film is provided with a plurality of protrusions, each of which has a groove, and a plurality of limiting holes are respectively formed on the bottom wall of the plurality of grooves. The grooves are used to accommodate the base, and the annular connecting part contacts the edge of the protrusion.

[0013] Optionally, the flexible film may be made of at least one of polyethylene, polypropylene, and polyvinyl chloride.

[0014] Optionally, the flexible film includes a central portion, two first portions, a second portion, a third portion, and a fourth portion connected to the central portion. The first portion includes a first sidewall portion connected to the central portion and a first top wall portion connected to the first sidewall portion. The second portion includes a second sidewall portion connected to the central portion and a second top wall portion connected to the second sidewall portion. When the cushioning package is in the packaged state, the first top wall portion and the second top wall portion are located above the central portion. The third portion and the fourth portion are arranged opposite to each other, and the first sidewall portion and the second sidewall portion are arranged opposite to each other.

[0015] The third section and the fourth section, both located away from the center, are provided with two hook and loop fasteners.

Detailed Implementation

[0037] The technical solutions of the present invention will now be described with reference to the accompanying drawings in the embodiments of the present invention.

[0038] The embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. The invention is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the invention.

[0039] Servers are high-value and precision devices, sensitive to impact and vibration during transportation. Therefore, specially designed internal cushioning packaging is necessary to protect them from impact and vibration. This protection primarily relies on padding, with EPE (Extra Polyethylene) being a commonly used material. Due to the characteristics of EPE, conventional server packaging padding typically uses a fixed packaging method. To protect all six sides of the server, a large amount of EPE is often used to form a wrapping structure, resulting in a high quantity of EPE and consequently higher costs. To address these issues, this invention provides a cushioning packaging component and box, which are described in detail below.

[0040] Firstly, referring to Figures 1 to 3 The cushioning packaging provided in this embodiment of the invention includes a flexible film 1 and a plurality of padding blocks 2 connected to the flexible film 1. The flexible film 1 has an inner surface 121 and an outer surface 111, and the padding blocks 2 protrude from the outer surface 111 of the flexible film 1. The cushioning packaging has a packaging state and a storage state. When the cushioning packaging is in the packaging state, the flexible film 1 wraps the packaged product, and the inner surface 121 of the flexible film 1 is in contact with the packaged product. When the cushioning packaging is in the storage state, the flexible film 1 is rolled into a cylindrical shape.

[0041] Specifically, the flexible film 1 is made of low-cost plastic materials, such as polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). The padding block 2 can be made of EPE, EPP (Expanded Polypropylene), etc. The flexible film 1 is preferably made of PE, and the padding block 2 is preferably made of EPE. The cushioning packaging provided in this embodiment of the invention, through clever design, integrates the padding block 2 onto the flexible film 1, providing precise protection to the required locations on the server. This saves on bridging EPE material, and the use of a low-cost PE flexible film 1 to bridge multiple padding blocks 2 reduces overall material costs, resulting in good economic efficiency. Connecting multiple padding blocks 2 with the flexible film 1 also keeps them in their corresponding positions, preventing displacement.

[0042] The packaged product can be a server, etc. The number of padding blocks 2 can be set according to actual needs, but the minimum number of padding blocks 2 is required to ensure that multiple padding blocks 2 are located on all six sides of the server when the cushioning package is in the packaged state. The six sides of the server refer to the top, bottom, left, right, front, and back sides of the server. (Refer to...) Figure 1When the cushioning package is in its packaged state, the shape of the flexible film 1 is adapted to the shape of the server, that is, the flexible film 1 is rectangular. When the cushioning package is in its packaged state, the internal dimensions of the flexible film 1 are adapted to the dimensions of the server. Specifically, this server is a rack-mount server, and the thickness of a rack-mount server is measured in U, where 1U is 4.445cm. The rack-mount server can have thicknesses of 1U, 2U, etc., with a 1U rack-mount server being a product that meets the specifications in terms of shape and has a thickness of 4.445cm.

[0043] Reference Figure 2 and Figure 3 The flexible film 1 also has a flattened state. (Refer to...) Figure 6 When packaging server 4, first lay the flexible film 1 flat, then place server 4 on the inner surface 121 of the flexible film 1, and then fold the flexible film 1 so that the flexible film 1 wraps around server 4. When the flexible film 1 is rolled into a cylindrical shape, multiple padding blocks 2 can be rolled inside.

[0044] In this embodiment of the invention, multiple padding blocks 2 are integrated onto a flexible film 1 to form a cushioning package. During packaging, the flexible film 1 wraps around the server, and the multiple padding blocks 2 can precisely protect the parts of the server that require protection, achieving on-demand protection of the server. The overall amount of padding blocks used is small, solving the technical problem of using a large amount of padding in the packaging of a single server in the prior art. In addition, there is no need to use EPE material to bridge the multiple padding blocks, reducing the use of EPE material and thus reducing the cost of the cushioning package.

[0045] Existing packaging structures occupy the same amount of space when not in use as when in use, which is detrimental to warehousing and transportation, resulting in high warehousing and transportation costs. In this embodiment of the invention, when the cushioning packaging is not in use, the flexible film 1 can be rolled into a cylindrical shape for storage, reducing the space occupied by the cushioning packaging when stored and giving the cushioning packaging good storage performance.

[0046] Reference Figure 7 , Figure 11 , Figure 12 and Figure 14 The flexible film 1 includes an outer film 11, on which a plurality of through-holes 112 are provided. The number of through-holes 112 is greater than or equal to the number of pad blocks 2. The pad block 2 includes a pad body 21 and a base 22 connected to the pad body 21. The pad body 21 passes through the through-holes 112. The cross-sectional area of ​​the base 22 is greater than the cross-sectional area of ​​the through-holes 112. The base 22 is located on the side of the outer film 11 closer to the inner surface 121.

[0047] Specifically, the limiting hole 112 penetrates the outer film 11 along its thickness direction, and the shape of the limiting hole 112 can be circular, rectangular, etc. Preferably, the number of limiting holes 112 is greater than the number of pad blocks 2; in this case, the excess limiting holes 112 are not integrated into the pad blocks 2. The cross-sectional shape of both the pad body 21 and the base 22 can be circular, rectangular, etc. The cross-section of the pad body 21 is the section of the pad body 21 perpendicular to its height direction.

[0048] The cross-sectional shapes of the pad body 21 and the base 22 are preferably rectangular. In this case, the length and width of the base 22 are both greater than the length and width of the pad body 21. The height of the base 22 is less than half the height of the pad body 21. The vertical cross-section of the pad block 2 is T-shaped, which is the cross-section of the pad block 2 parallel to its height direction. When the vertical cross-section of the pad block 2 is T-shaped, it is convenient to integrate with the flexible film 1.

[0049] The limiting hole 112 is used to limit the position of the pad block 2. When the pad block 2 is assembled on the flexible film 1, the limiting hole 112 can quickly position the pad block 2. The limiting hole 112 can limit the base 22, and the base 22 can prevent the pad block 2 from falling off the flexible film 1. After adjusting the arrangement of multiple limiting holes 112, the arrangement of multiple pad blocks 2 is adjusted accordingly to match the buffer protection requirements of servers with different configurations. In addition, by setting the number of limiting holes 112 to be greater than the number of pad blocks 2, it is convenient to add pad blocks 2 to the limiting holes 112 according to the protection requirements of different servers.

[0050] Reference Figure 11 and Figure 12 The flexible film 1 also includes an inner film 12 stacked with the outer film 11, and the base 22 is located between the outer film 11 and the inner film 12.

[0051] Specifically, the flexible film 1 comprises a two-layer structure: an outer film 11 with a limiting hole 112, and an inner film 12 without holes. The inner film 12 is heat-pressed together with the outer film 11 to limit the base 22 and enhance the limiting effect. The material of the outer film 11 is the same as that of the inner film 12, preferably PE. The material of the outer film 11 can also be different from that of the inner film 12; for example, the outer film 11 can be made of PE, and the inner film 12 can be made of PP. The shape and size of the inner film 12 can be completely identical to those of the outer film 11. In this embodiment of the invention, the inner film 12 effectively limits the base 22, preventing it from detaching.

[0052] Reference Figure 13 and Figure 14The outer film 11 also has a plurality of annular connecting parts 113, which are located on the outside of a plurality of limiting holes 112 respectively, and each annular connecting part 113 is connected to the inner film 12 by hot pressing.

[0053] Specifically, hot pressing is a process that bonds two or more objects together by applying heat and pressure. Figure 13 This is a schematic diagram of the outer film 11 and the inner film 12 before hot pressing. Figure 14 This is a schematic diagram showing the outer film 11 and the inner film 12 after hot pressing. (Refer to...) Figure 12 and Figure 13 Before hot pressing, place the pad block 2, ensuring that the pad body 21 of the pad block 2 passes through the limiting hole 112, and the base 22 is located between the outer film 11 and the inner film 12. During hot pressing, heat press the annular connecting part 113 to the corresponding position on the inner film 12. The edges of the outer film 11 and the inner film 12 can also be connected by hot pressing.

[0054] The number of annular connecting portions 113 is equal to the number of limiting holes 112. The limiting holes 112 are located inside the annular connecting portions 113. The shape of the annular connecting portions 113 can be the same as the shape of the limiting holes 112. For example, when the shape of the limiting holes 112 is rectangular, the shape of the annular connecting portions 113 is also rectangular. In this case, the length and width of the annular connecting portions 113 are both greater than the length and width of the limiting holes 112.

[0055] In this embodiment of the invention, by connecting each annular connecting part 113 to the inner film 12 through heat pressing, the base 22 can be limited and prevented from moving. Furthermore, the connection between the outer film 11 and the inner film 12 can be achieved. The cushioning packaging provided in this embodiment of the invention uses a flexible PE film 1 that is rollable and cost-effective. By opening limiting holes 112 and heat-pressing the outer film 11 and the inner film 12 together, the padding block 2 is fixed. By arranging the limiting holes 112, the padding blocks 2 are arranged, thereby providing precise protection for the parts of the server that require protection, and protecting the server as needed.

[0056] In other embodiments, each annular connecting portion 113 is connected to the inner film 12 by adhesive, and the edge of the outer film 11 is connected to the edge of the inner film 12 by adhesive.

[0057] Reference Figures 7 to 10 The pad body 21 has a first end away from the base 22 and a second end close to the base 22. The cross-sectional area of ​​the second end of the pad body 21 is equal to the cross-sectional area of ​​the limiting hole 112. The cross-sectional area of ​​the pad body 21 gradually decreases from the second end of the pad body 21 to the first end of the pad body 21.

[0058] Specifically, the vertical cross-section of the padding body 21 is trapezoidal, which is the section of the padding body 21 parallel to its height direction. The direction from the second end of the padding body 21 to the first end can be referenced... Figure 9 The direction indicated by arrow A. The shape of the cross-section of the second end of the pad body 21 is consistent with the shape of the limiting hole 112. For example, when the shape of the limiting hole 112 is rectangular, the shape of the cross-section of the limiting hole 112 is also rectangular. The area of ​​the cross-section of the second end of the pad body 21 is equal to the area of ​​the cross-section of the limiting hole 112, which facilitates the limiting hole 112 in limiting the second end of the pad body 21. The area of ​​the cross-section of the first end of the pad body 21 is smaller than the area of ​​the cross-section of the second end of the pad body 21. In this embodiment of the invention, by setting the cross-sectional area of ​​the pad body 21 to gradually decrease from the second end of the pad body 21 to the first end of the pad body 21, it is convenient for the first end of the pad body 21 to pass through the limiting hole 112.

[0059] Reference Figure 14 The outer film 11 has a plurality of protrusions 114, each of which has a groove. A plurality of limiting holes 112 are respectively opened on the bottom wall of the plurality of grooves. The grooves are used to accommodate the base 22. The annular connecting part 113 is in contact with the edge of the protrusion 114.

[0060] Specifically, the number of protrusions 114 is equal to the number of limiting holes 112. The opening of the groove faces the inner membrane 12, and the shape and size of the groove match the shape and size of the base 22. The shape of the inner ring of the annular connecting portion 113 is consistent with the shape of the cross-section of the protrusion 114. For example, when the cross-section of the protrusion 114 is rectangular, the shape of the inner ring of the annular connecting portion 113 is also rectangular. The inner ring of the annular connecting portion 113 contacts the edge of the protrusion 114, ensuring the limiting effect on the base 22.

[0061] The flexible film 1 is made of at least one of polyethylene, polypropylene, and polyvinyl chloride.

[0062] Specifically, the flexible film 1 can be made of only one material, such as polyethylene, polypropylene, or polyvinyl chloride. The preferred material for the flexible film 1 is polyethylene. Flexible films 1 made of PE are water-resistant, moisture-resistant, corrosion-resistant, low-temperature resistant, and wear-resistant, and are also inexpensive.

[0063] Reference Figures 1 to 6The flexible film 1 includes a central portion 13, two first portions 14, a second portion 15, a third portion 16, and a fourth portion 17 connected to the central portion 13. The first portion 14 includes a first sidewall portion 141 connected to the central portion 13 and a first top wall portion 142 connected to the first sidewall portion 141. The second portion 15 includes a second sidewall portion 151 connected to the central portion 13 and a second top wall portion 152 connected to the second sidewall portion 151. When the cushioning package is in the packaged state, the first top wall portion 142 and the second top wall portion 152 are located above the central portion 13. The third portion 16 and the fourth portion 17 are arranged opposite to each other, and the first sidewall portion 141 and the second sidewall portion 151 are arranged opposite to each other.

[0064] Two hook and loop fasteners 18 are provided at the end of the third section 16 away from the center section 13 and at the end of the fourth section 17 away from the center section 13. Hook and loop fasteners 19 for cooperating with the hook and loop fasteners 18 on the third section 16 and the fourth section 17 are provided on the first side wall section 141 and the second side wall section 151. Multiple hook and loop fasteners 18 are provided at the end of the first top wall section 142 away from the first side wall section 141. Multiple hook and loop fasteners 19 for cooperating with the multiple hook and loop fasteners 18 on the first top wall section 142 are provided at the end of the second top wall section 152 away from the second side wall section 151.

[0065] Specifically, the central portion 13, the first section 14, the second section 15, the third section 16, and the fourth section 17 are all rectangular in shape. When this cushioning package is used to package the server, the central portion 13 contacts the bottom surface of the server, the first top wall portion 142 and the second top wall portion 152 contact the top surface of the server, and the third section 16, the fourth section 17, the first side wall portion 141, and the second side wall portion 151 contact the four sides of the server. The third section 16 and the fourth section 17 are preferably located on both sides of the server's length direction, while the first side wall portion 141 and the second side wall portion 151 are preferably located on both sides of the server's width direction.

[0066] Two hook-and-loop fasteners 19 are provided on the first sidewall portion 141. One hook-and-loop fastener 19 is used to engage with the hook-and-loop fastener 18 on the third portion 16, and the other hook-and-loop fastener 19 is used to engage with the hook-and-loop fastener 17 on the fourth portion 17. Two hook-and-loop fasteners 19 are provided on the second sidewall portion 151. One hook-and-loop fastener 19 is used to engage with the hook-and-loop fastener 18 on the third portion 16, and the other hook-and-loop fastener 19 is used to engage with the hook-and-loop fastener 17 on the fourth portion 17. Three hook-and-loop fasteners 18 are specifically provided on the end of the first top wall portion 142 away from the first sidewall portion 141. In this embodiment of the invention, by providing the hook-and-loop fasteners 18 and hook-and-loop fasteners 19, the position of the flexible film 1 can be fixed after the flexible film 1 wraps around the server, preventing the flexible film 1 from shifting, thereby preventing the position of the pad block 2 from shifting.

[0067] In other embodiments, two pieces of packaging tape are attached to one end of the third portion 16 away from the center portion 13 and one end of the fourth portion 17 away from the center portion 13, and multiple pieces of packaging tape are attached to one end of the first top wall portion 142 away from the first side wall portion 141. In this embodiment, the flexible film 1 is fixed in position by the packaging tape.

[0068] Reference Figure 1 and Figure 3 The number of padding blocks 2 connected to the first top wall portion 142 is four, the number of padding blocks 2 connected to the second top wall portion 152 is three, the number of padding blocks 2 connected to the first side wall portion 141 is five, the number of padding blocks 2 connected to the second side wall portion 151 is five, the number of padding blocks 2 connected to the third portion 16 is four, the number of padding blocks 2 connected to the fourth portion 17 is four, and the number of padding blocks 2 connected to the center portion 13 is seven.

[0069] At least two pad blocks 2 have different densities, or each pad block 2 has the same density.

[0070] Specifically, padding blocks 2 of different densities can be used depending on the server type or center of gravity. Different density padding blocks 2 can also be used to meet different cushioning effect requirements. In this embodiment of the invention, by setting unequal densities for the padding blocks 2, different cushioning effects can be achieved to match different cushioning needs.

[0071] The processing procedure for the above-mentioned cushioning packaging is as follows:

[0072] The first step is to process the outer film 11, and then to open multiple through-holes 112 on the outer film 11. The outer film 11 is made of PE.

[0073] The second step is to process the inner film 12. The inner film 12 is made of PE, and its shape and size are consistent with those of the outer film 11.

[0074] The third step is to process the pad block 2. The pad block 2 is made of EPE and includes a pad body 21 and a base 22 connected to the pad body 21. The cross-sectional area of ​​the base 22 is larger than the cross-sectional area of ​​the limiting hole 112. The cross-sectional area of ​​the second end of the pad body 21 is equal to the cross-sectional area of ​​the limiting hole 112. The cross-sectional area of ​​the pad body 21 gradually decreases from the second end of the pad body 21 to the first end of the pad body 21.

[0075] Step 4, refer to Figures 12 to 13 In this process, multiple pad blocks 2 are sequentially installed on multiple limiting holes 112. Among them, the pad body 21 passes through the limiting hole 112, and the base 22 is located between the outer film 11 and the inner film 12.

[0076] Fifth step: sequentially heat-press the multiple annular connecting portions 113 on the outer film 11 to the inner film 12. After heat pressing, as shown... Figure 14 As shown, the annular connecting portion 113 is in contact with the edge of the protrusion 114.

[0077] Conventional packaging structures use a large amount of EPE (Extra Polyethylene) to protect the server's center of gravity and vulnerable points, resulting in excessive material usage. Furthermore, the unused volume of the packaging structure is the same after production, occupying significant space during storage and transportation, leading to high material and storage costs. The cushioning packaging provided in this invention uses a flexible, low-cost PE film 1 that can be rolled up and stored. The padding blocks 2 are fixed by creating limiting holes 112 and heat-pressing the outer film 11 and inner film 12 together. The padding blocks 2 are arranged by arranging the limiting holes 112, thus providing precise protection for the server's critical areas and protecting the server as needed.

[0078] The cushioning packaging provided in this invention, through its ingenious design, integrates padding blocks 2 onto a flexible film 1, providing precise protection to the areas of the server requiring protection as needed. This saves on bridging EPE material, and the use of a low-cost PE flexible film 1 to bridge multiple padding blocks 2 reduces overall material costs, resulting in good economic efficiency. Furthermore, the flexible film 1 can be rolled up for storage, effectively accommodating multiple padding blocks 2 when not in use, minimizing storage space and providing good warehousing capabilities. Additionally, the multiple EPE padding blocks 2 provide precise protection to the server's required areas, accurately absorbing impact energy for specific parts. Different densities of padding blocks 2 are used depending on the server and its center of gravity, ensuring good safety. The limiting hole 112 can be left unfilled, allowing for selection of padding block 2 installation based on server configuration changes, ensuring compatibility with different server configurations and providing good compatibility. In summary, the cushioning packaging provided in this invention offers good economic efficiency, warehousing efficiency, safety, and compatibility.

[0079] Secondly, referring to Figure 15 This invention provides a packaging box, including a box body 3 and a cushioning package disposed within the box body 3 according to any of the first aspects. The cushioning package includes a flexible film 1 and a plurality of padding blocks 2 connected to the flexible film 1. The flexible film 1 has an inner surface 121 and an outer surface 111, and the padding blocks 2 protrude from the outer surface 111 of the flexible film 1. The cushioning package has a packaged state and a stored state. When the cushioning package is in the packaged state, the flexible film 1 wraps the packaged product, and the inner surface 121 of the flexible film 1 is in contact with the packaged product. When the cushioning package is in the stored state, the flexible film 1 is rolled into a cylindrical shape.

[0080] In this embodiment of the invention, multiple padding blocks 2 are integrated onto a flexible film 1 to form a cushioning package. During packaging, the flexible film 1 wraps around the server, and the multiple padding blocks 2 can precisely protect the parts of the server that require protection, achieving on-demand protection of the server. The overall amount of padding blocks used is small, solving the technical problem of using a large amount of padding in the packaging of a single server in the prior art. In addition, there is no need to use EPE material to bridge the multiple padding blocks, reducing the use of EPE material and thus reducing the cost of the cushioning package.

[0081] Existing packaging structures occupy the same amount of space when not in use as when in use, which is detrimental to warehousing and transportation, resulting in high warehousing and transportation costs. In this embodiment of the invention, when the cushioning packaging is not in use, the flexible film 1 can be rolled into a cylindrical shape for storage, reducing the space occupied by the cushioning packaging when stored and giving the cushioning packaging good storage performance.

[0082] Box 3 can specifically be a 0201 type cardboard box. The 0201 type cardboard box has an opening at the top and bottom, and the sides are closed. The top and bottom are parallel and facing each other. The top and bottom flaps are uniform, and the left and right flaps face each other. The width of the left and right flaps is half of its length, and the width of the front and back flaps is exactly half of the width of the cardboard box. Because of its sealing method, the 0201 type cardboard box must be sealed with tape to ensure that the cardboard box is completely sealed.

[0083] The flexible film 1 includes an outer film 11, on which a plurality of through-holes 112 are provided. The number of through-holes 112 is greater than or equal to the number of pad blocks 2. The pad block 2 includes a pad body 21 and a base 22 connected to the pad body 21. The pad body 21 passes through the through-holes 112. The cross-sectional area of ​​the base 22 is greater than the cross-sectional area of ​​the through-holes 112. The base 22 is located on the side of the outer film 11 closer to the inner surface 121.

[0084] The flexible film 1 also includes an inner film 12 stacked with the outer film 11, and the base 22 is located between the outer film 11 and the inner film 12.
