Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a pearl cotton cushioning pad, including a packaging structure for the pearl cotton cushioning pad, and a packaging product including the above-mentioned packaging structure. Background Technology

[0002] EPE foam cushioning pads are a common cushioning packaging material, widely used in the packaging of various products such as lamps, home appliances, medical devices, handicrafts, furniture, and alcoholic beverages. Currently, most EPE foam cushioning pads are rectangular blocks. When packaging an item, a portion of the material is removed from the corresponding area of ​​the EPE foam cushioning pad according to the outline of the item. The material then wraps around the removed area, thus achieving cushioning protection (e.g., ...). Figure 1 As shown, area A is the part that was excavated.

[0003] However, due to the wide variety of products being packaged, even within the same major product category, there are different types (such as downlights, spotlights, and track lights in lighting fixtures); and because the existing pearl cotton cushioning pads have poor structural versatility, they are difficult to directly adapt to various products. Furthermore, during the packaging process, material in specific areas of the pearl cotton cushioning pads needs to be manually removed as required, which reduces packaging efficiency, increases manual labor intensity, hinders automated production, and also causes material waste. Utility Model Content

[0004] The primary objective of this invention is to provide a pearl cotton cushioning pad that is highly versatile, practical, and easy to store and transport.

[0005] The second objective of this invention is to provide a packaging structure with the aforementioned pearl cotton cushioning pad.

[0006] The third objective of this utility model is to provide a packaging product having the above-mentioned structure.

[0007] To achieve the primary objective of this utility model, a pearl cotton cushioning pad is provided. The pearl cotton cushioning pad is rectangular in shape, wherein die-cutting lines are provided at all four corners or all four sides of the pearl cotton cushioning pad, and the die-cutting lines penetrate the pearl cotton cushioning pad in the thickness direction. When die-cutting lines are provided at all four corners of the pearl cotton cushioning pad, each corner can be independently stretched and unfolded away from the center of the pearl cotton cushioning pad through the corresponding die-cutting lines. When die-cutting lines are provided at all four sides of the pearl cotton cushioning pad, each side can be independently stretched and unfolded away from the center of the pearl cotton cushioning pad through the corresponding die-cutting lines.

[0008] As can be seen from the above, by pre-forming die-cutting lines on the EPE foam cushioning pad, the packaging process allows for stretching and unfolding of portions of the EPE foam cushioning pad according to the shape of the packaged item, thus adapting to the contour of the packaged item and providing better wrapping and effective cushioning. Furthermore, the die-cutting line design also allows the EPE foam cushioning pad to adapt to packaged items of different sizes and shapes, improving its versatility. Moreover, it eliminates the need for material removal during packaging, improving both packaging efficiency and material utilization. In addition, compared to traditional rectangular block-shaped EPE foam cushioning pads, this EPE foam cushioning pad, with its die-cutting lines, can be stretched and unfolded as needed during packaging and remains in its initial contracted state during storage and transportation, thereby reducing the space required for storage and transportation and lowering transportation costs.

[0009] A preferred embodiment is that when die-cutting line groups are provided at all four corners of the pearl cotton cushioning pad, the die-cutting line groups include a first line group, which includes a first line set and a second line set. The first line set includes at least one first cut and two second cuts arranged in a mirror-symmetrical manner. The first cut is located between the two second cuts.

Both the first and third cuts are U-shaped, with the openings of the first and third cuts facing each other and interlocking, and the second vertical segment is inserted into the opening of the third cut closest to itself.

[0010] As can be seen from the above, the design of the first thread group allows the corners of the pearl cotton cushioning pad to be stretched into a mesh structure when stretched. This ensures that the corners remain connected to the main body of the pearl cotton cushioning pad, and the mesh structure can accommodate part of the packaged item, thus eliminating the need to remove material from the pearl cotton cushioning pad and improving packaging convenience and efficiency.

[0011] A further embodiment includes a second line group within the first line group. The second line group comprises a third line set and a fourth line set. The third line set includes at least one fourth cut and two mirror-symmetrical fifth cuts. The fourth cut is located between the two fifth cuts and includes a third horizontal segment, two fourth connecting segments, and two fourth vertical segments. A fourth connecting segment connects the third horizontal segment and the fourth vertical segment. The fifth cut includes a fifth connecting segment, a fifth vertical segment, and a second extension segment. The fifth connecting segment connects... The fifth vertical segment is located between the fifth vertical segment and the second outer extension segment. The fifth vertical segment is positioned close to the fourth vertical segment, and the second outer extension segment extends to the edge. The fourth line set is located inside the third line set. The fourth line set includes two or more sixth cuts. The sixth cut includes a fourth horizontal segment, two sixth connecting segments, and two sixth vertical segments. A sixth connecting segment connects the fourth horizontal segment and a sixth vertical segment. Both the fourth and sixth cuts are U-shaped. The openings of the fourth and sixth cuts face each other and interlock. The fifth vertical segment is inserted into the opening of the sixth cut closest to itself.

[0012] As can be seen from the above, by adding a second thread group, the pearl cotton cushioning pad can achieve two-stage stretching and unfolding, so as to meet more packaging needs, adapt to more different types of packaged materials, and improve the practicality and application range of the pearl cotton cushioning pad.

[0013] A further embodiment is that the second extension segment includes a horizontal line portion and a diagonal line portion, with the horizontal line portion connecting the fifth connecting segment and the diagonal line portion, and the diagonal line portion extending towards the first line set at an inclination to the horizontal line portion to the edge portion; the diagonal line portions at two adjacent corners are arranged in parallel.

[0014] As can be seen from the above, this design makes the processing of the die-cutting line group more convenient and ensures that the second line group can be reliably stretched and unfolded.

[0015] Another preferred embodiment is that when die-cutting line groups are set on all four sides of the pearl cotton cushioning pad, the die-cutting line groups include a third line group, the third line group includes a fifth line set and a sixth line set, the fifth line set includes two or more seventh cuts and two mirror-symmetrical eighth cuts, the two or more seventh cuts are located between the two eighth cuts, the seventh cut includes a fifth horizontal segment, two seventh connecting segments and two seventh vertical segments, a seventh connecting segment connects the fifth horizontal segment and the seventh vertical segment, the eighth cut includes an eighth connecting segment, an eighth vertical segment and a third extension segment, and the... The eighth connecting segment connects the eighth vertical segment and the third extension segment. The eighth vertical segment is set close to the seventh vertical segment, and the third extension segment is parallel to its corresponding edge. The sixth line set is located inside the fifth line set. The sixth line set includes two or more ninth cuts. The ninth cut includes the sixth horizontal segment, two ninth connecting segments, and two ninth vertical segments. One ninth connecting segment connects the sixth horizontal segment and one ninth vertical segment. The seventh and ninth cuts are both U-shaped. The openings of the seventh and ninth cuts face each other and are interlocked. The eighth vertical segment is inserted into the opening of the ninth cut closest to itself.

[0016] As can be seen from the above, the design of the third thread group allows the edge of the pearl cotton cushioning pad to be stretched into a mesh structure when the edge is stretched and unfolded. On the one hand, this keeps the edge connected to the main body of the pearl cotton cushioning pad, and on the other hand, the mesh structure can be used to accommodate part of the structure of the packaged item, thus eliminating the need to remove material from the pearl cotton cushioning pad and improving packaging convenience and efficiency.

[0017] A further embodiment includes a fourth line group within the die-cutting line group, located inside the third line group. The fourth line group comprises a seventh line set and an eighth line set. The seventh line set includes at least one tenth cut and two mirror-symmetrically arranged eleventh slits. The tenth cut is located between the two eleventh slits and includes a seventh horizontal segment, two tenth connecting segments, and two tenth vertical segments. One tenth connecting segment connects the seventh horizontal segment and the tenth vertical segment. The eleventh slit includes an eleventh connecting segment, an eleventh vertical segment, and a fourth extension segment. The eleventh connecting segment connects the eleventh vertical segment and the fourth extension segment, with the eleventh vertical segment positioned close to the tenth vertical segment. The fourth extension segment is parallel to its corresponding edge. An angle dividing line is provided between the protruding end of the third extension segment and the protruding end of the fourth extension segment. The angle dividing line penetrates the pearl cotton cushioning pad in the thickness direction. The eighth line set is located inside the seventh line set. The eighth line set includes two or more twelfth cuts. The twelfth cut includes an eighth horizontal segment, two twelfth connecting segments, and two twelfth vertical segments. A twelfth connecting segment connects the eighth horizontal segment and the twelfth vertical segment. The tenth cut and the twelfth cut are both U-shaped. The openings of the tenth cut and the twelfth cut are set facing each other and interlocked. The eleventh vertical segment is inserted into the opening of the twelfth cut closest to itself.

[0018] As can be seen from the above, by adding a fourth thread group, the pearl cotton cushioning pad can achieve two-stage stretching and unfolding, so as to meet more packaging needs, adapt to more different types of packaged materials, and improve the practicality and application range of the pearl cotton cushioning pad.

[0019] A further proposed solution is that the die-cutting line group also includes a fifth line group, located inside the fourth line group. The fifth line group includes two mirror-symmetrically arranged thirteenth and fourteenth cuts. The thirteenth cut includes a thirteenth connecting segment, a thirteenth vertical segment, and a fifth outer extension segment. The thirteenth connecting segment connects the thirteenth vertical segment and the fifth outer extension segment. The fifth outer extension segment is parallel to its corresponding edge, and the corner dividing line extends to the protruding end of the fifth outer extension segment. The fourteenth cut includes a ninth horizontal segment, two fourteenth connecting segments, and two fourteenth vertical segments. One fourteenth connecting segment connects the ninth horizontal segment and the fourteenth connecting segment. The fourteenth cut is U-shaped, and the thirteenth vertical segment is inserted into the opening of the fourteenth cut.

[0020] As can be seen from the above, by adding a fifth thread group, the pearl cotton cushioning pad can achieve multi-level stretching and expansion, further enhancing and expanding the expansion range of the pearl cotton cushioning pad, while also further adapting to more different types of packaging materials, further improving the practicality and applicability of the pearl cotton cushioning pad.

[0021] To achieve the second objective of this utility model, this utility model provides a packaging structure, including a packaging box and the aforementioned pearl cotton cushioning pad, wherein the pearl cotton cushioning pad is installed inside the packaging box.

[0022] As can be seen from the above, the packaging structure, by using the aforementioned pearl cotton cushioning pad, can better package different types of items and adapt to different types of items. At the same time, there is no need to remove the pearl cotton cushioning pad during the packaging process, which helps to improve packaging efficiency. In addition, since the pearl cotton cushioning pad is initially shrunk to its smallest volume, the space required for storage and transportation is reduced, thus lowering transportation costs.

[0023] To achieve the third objective of this utility model, this utility model provides a packaging product, including a packaged item and the above-mentioned packaging structure, wherein the packaged item is placed on a pearl cotton cushioning pad, and the pearl cotton cushioning pad can be stretched and unfolded.

[0024] As can be seen from the above, the packaging structure of the packaged products eliminates the need to remove the pearl cotton cushioning pad during the packaging process, which helps to improve packaging efficiency.

[0025] A further option is to package the light source as downlights, spotlights, or grille lights.

[0026] As can be seen from the above, the use of pearl cotton cushioning pads enables the packaging structure to adapt to different types of packaged items, thereby improving the practicality and applicability of the packaging structure. Attached Figure Description

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0039] First embodiment of pearl cotton cushioning pad Reference Figure 2The pearl cotton cushioning pad 100 is rectangular in shape. In this embodiment, the pearl cotton cushioning pad 100 is preferably square in shape. In addition, each of the four corners of the pearl cotton cushioning pad 100 is provided with a die-cutting line group 101, which penetrates the pearl cotton cushioning pad 100 in the thickness direction. Each corner 102 can be independently stretched and unfolded away from the center of the pearl cotton cushioning pad 100 by the corresponding die-cutting line group 101. Preferably, the die-cutting line group 101 includes a first line group 1 and a second line group 2.

[0040] It should be noted that after the pearl cotton cushioning pad 100 is stretched and unfolded to the four corners, its overall size will increase proportionally with the stretching and unfolding layers; however, the enlarged size of the pearl cotton cushioning pad 100 after stretching and unfolding will vary depending on the outer size of the pearl cotton cushioning pad 100 and the size of the internal die-cutting line group 101.

[0041] The first thread group 1 includes a first thread set 11 and a second thread set 12; the first thread set 11 includes at least one first cut 111 and two second cuts 112, the two second cuts 112 are arranged in a mirror symmetrical manner, the first cut 111 and the second cuts 112 are distributed at intervals along the same direction, which is perpendicular to a diagonal of the square pearl cotton cushioning pad 100; wherein, the first cut 111 is located between the two second cuts 112.

[0042] The first cut 111 includes a first horizontal segment 1111, two first connecting segments 1112 and two first vertical segments 1113. The two first connecting segments 1112 are arranged in a mirror image symmetrically, and the two first vertical segments 1113 are arranged in a mirror image symmetrically. The two first connecting segments 1112 and the two first vertical segments 1113 correspond one-to-one, so that one first connecting segment 1112 connects the first horizontal segment 1111 and the one first vertical segment 1113.

[0043] The second cut 112 includes a second connecting segment 1121, a second vertical segment 1122, and a first outer extension segment 1123. The second connecting segment 1121 connects the second vertical segment 1122 and the first outer extension segment 1123. The second vertical segment 1122 is positioned close to the first vertical segment 1113 and is parallel to the first vertical segment 1113. The first outer extension segment 1123 extends to the edge of the pearl cotton cushioning pad 100. Preferably, the first outer extension segment 1123 is a straight line, and both the first outer extension segment 1123 and the first horizontal segment 1111 are preferably perpendicular to the diagonal of the square pearl cotton cushioning pad 100.

[0044] The second line set 12 is located inside the first line set 11. The second line set 12 includes two or more third cuts 121, which are spaced apart along a direction parallel to the distribution of the first cut 111 and the second cut 112. Each third cut 121 includes a second horizontal segment 1211, two third connecting segments 1212, and two third vertical segments 1213. The two third connecting segments 1212 and the two third vertical segments 1213 are arranged in a mirror-symmetrical configuration, and the third vertical segments 1213 are parallel to the first vertical segment 1113. The two third connecting segments 1212 and the two third vertical segments 1213 correspond one-to-one, such that one third connecting segment 1212 connects the second horizontal segment 1211 and the third vertical segment 1213.

[0045] Furthermore, the design of the first cut 111 and the third cut 121 are both U-shaped. The openings of the first cut 111 and the third cut 121 face each other and interlock, meaning the first vertical segment 1113 is inserted into the opening of the third cut 121, and the third vertical segment 1213 is inserted into the opening of the first cut 111. The two vertical segments of the same cut are not located in the openings of another facing cut. The second vertical segment 1122 is inserted into the opening of the third cut 121 closest to itself. It is understood that there are gaps between the first cut 111, the second cut 112, and the third cut 121.

[0046] The second line group 2 is located inside the first line group 1. The second line group 2 includes a third line set 21 and a fourth line set 22. The third line set 21 includes at least one fourth cut 212 and two fifth cuts 212, which are arranged in a mirror-symmetric manner. The fourth cuts 212 and the fifth cuts 212 are distributed at intervals along the distribution direction of the first cut 111 and the second cut 112, and the fourth cut 212 is located between the two fifth cuts 212.

[0047] The fourth cut 212 includes a third horizontal segment 2111, two fourth connecting segments 2112, and two fourth vertical segments 2113. The two fourth connecting segments 2112 and the two fourth vertical segments 2113 are arranged in a mirror-symmetrical manner, and the two fourth connecting segments 2112 and the two fourth vertical segments 2113 correspond one-to-one, so that one fourth connecting segment 2112 connects the third horizontal segment 2111 and the one fourth vertical segment 2113. The fourth vertical segment 2113 is parallel to the first vertical segment 1113. In addition, the fourth cut 212 and the first cut 111 can be distributed along the distribution direction of the first line group 1 and the second line group 2, or the fourth cut 212 and the first cut 111 can be staggered in the distribution direction.

[0048] The fifth cut 212 includes a fifth connecting segment 2121, a fifth vertical segment 2122, and a second extension segment 2123. The fifth connecting segment 2121 connects the fifth vertical segment 2122 and the second extension segment 2123. The fifth vertical segment 2122 is located close to the fourth vertical segment 2113 and is parallel to the fourth vertical segment 2113. The second extension segment 2123 extends to the edge of the pearl cotton cushioning pad 100. Preferably, the second extension segment 2123 includes a horizontal line portion 23231 and a diagonal line portion 23232. The horizontal line portion 23231 is connected between the fifth connecting segment 2121 and the diagonal line portion 23232, and the diagonal line portion 23232 extends obliquely from the horizontal line portion 23231 toward the edge of the pearl cotton buffer pad 100 towards the first line set 11. In addition, the diagonal line portions 23232 at two adjacent corners 102 are preferably arranged in parallel, such that the diagonal line portion 23232 is perpendicular to one side of the square block-shaped pearl cotton buffer pad 100. This design makes the processing of the die-cutting line set 101 more convenient and ensures that the second line set 2 can be reliably stretched and unfolded.

[0049] The fourth line set 22 is located inside the third line set 21. The fourth line set 22 includes two or more sixth cuts 221, which are spaced apart along a direction parallel to the distribution of the first cut 111 and the second cut 112. Each sixth cut 221 includes a fourth horizontal segment 2211, two sixth connecting segments 2212, and two sixth vertical segments 2213. The two sixth connecting segments 2212 and the two sixth vertical segments 2213 are arranged in a mirror-symmetrical configuration, and the sixth vertical segments 2213 are parallel to the first vertical segment 1113. The two sixth connecting segments 2212 and the two sixth vertical segments 2213 correspond one-to-one, such that a sixth connecting segment 2212 connects the fourth horizontal segment 2211 and the sixth vertical segment 2213.

[0050] Furthermore, the design of the fourth cut 212 and the sixth cut 221 results in both cuts being U-shaped. The openings of the fourth cut 212 and the sixth cut 221 face each other and interlock; that is, the fourth vertical segment 2113 is inserted into the opening of the sixth cut 221, and the sixth vertical segment 2213 is inserted into the opening of the fourth cut 212. The two vertical segments of the same cut are not located within the openings of another facing cut. The fifth vertical segment 2122 is inserted into the opening of the sixth cut 221 closest to itself. It is understood that there are gaps between the fourth cut 212, the fifth cut 212, and the sixth cut 221.

[0051] Furthermore, the sixth cut 221 and the third cut 121 can be distributed along the distribution direction of the first line group 1 and the second line group 2, or the sixth cut 221 and the third cut 121 can be staggered in the distribution direction. Moreover, the fourth cut 212 is oriented in the same direction as the first cut 111, and the sixth cut 221 is oriented in the same direction as the third cut 121.

[0052] like Figures 3 to 5 As shown, by designing the cutting path and arrangement of the first thread group 1, when packaging, cushioning, and supporting the packaged item, at least one corner 102 of the pearl cotton cushioning pad 100 can be pulled. The pulled corner 102, under pressure, forces the first thread group 1 to stretch and unfold, thereby causing the first thread group 1 to deform synchronously along the stretching direction, forming a mesh support structure with hollowed-out gaps. Through this mesh support structure, on the one hand, the corner 102 and the pearl cotton cushioning pad 100 body maintain a stable connection, preventing the corner 102 from detaching or separating from the pearl cotton cushioning pad 100; on the other hand, the hollowed-out area of ​​the mesh support structure can directly adapt to and accommodate local protrusions or irregular structures of the packaged item (such as the mounting spring 1011 of the lamp 10), thus eliminating the need for additional material removal from the pearl cotton cushioning pad 100, thereby simplifying the packaging process and improving the convenience and efficiency of packaging operations.

[0053] Combination Figure 6 and Figure 7 A second thread group 2 is added to the pearl cotton cushioning pad 100, so that after the corner 102 of the pearl cotton cushioning pad 100 is stretched and unfolded once by the first thread group 1, it can also be stretched and unfolded a second time along the guide of the second thread group 2. The secondary stretching and unfolding function given by the second thread group 2 can further expand the deformation range and contour adaptation range of the cushioning pad. It can not only meet the more complex packaging needs such as irregular structures and multiple protrusions, but also adapt to more sizes and shapes of packaged items, effectively solving the problem of the single adaptability of traditional cushioning pads, and further improving the practical performance and overall applicability of the pearl cotton cushioning pad 100.

[0054] It should be noted that this embodiment uses a square block (a special rectangular block) as an example for illustration. When the pearl cotton cushioning pad 100 is a rectangular block instead of a square block, its structural design is similar to the design described in this embodiment, so it will not be repeated here. In addition, the pearl cotton cushioning pad 100 may also only have the first thread group 1 or the second thread group 2.

[0055] In summary, by pre-setting the die-cutting line group 101 on the pearl cotton cushioning pad 100, external force can be applied to the corners 102 of the pearl cotton cushioning pad 100 as needed according to the shape of the packaged object during the packaging process. This allows the pearl cotton cushioning pad 100 to be stretched and unfolded once or twice at each corner 102 position through the die-cutting line group 101, thereby precisely fitting the contour of the packaged object and forming a comprehensive cushioning and wrapping structure, effectively improving the cushioning and protective performance. Secondly, based on the design of the die-cutting line group 101, the pearl cotton cushioning pad 100 can be adapted to packaged objects of different sizes and shapes through stretching and deformation, greatly improving the versatility of the pearl cotton cushioning pad 100. Furthermore, under the action of the stretched and unfolded die-cutting line group 101, there is no need to remove material from the pearl cotton cushioning pad 100, which simplifies the packaging operation process, improves packaging efficiency, avoids material waste, and improves the utilization rate of pearl cotton material. In addition, compared with traditional rectangular block-shaped pearl cotton cushioning pads, the pearl cotton cushioning pad 100 provided in this application is in an initial shrinkage state during the storage and transportation stage, occupying less space, which can significantly reduce the space occupancy rate and transportation costs during the storage and transportation process.

[0056] Second embodiment of pearl cotton cushioning pad Reference Figure 8 The difference between this embodiment and the first embodiment of the pearl cotton cushioning pad lies in the setting position of the die-cutting line group. Specifically, in this embodiment: The die-cutting line groups are located at the edges 103 of the pearl cotton cushioning pad 100, meaning that die-cutting line groups are provided at all four sides of the pearl cotton cushioning pad 100, allowing each edge 103 to be independently stretched and unfolded away from the center of the pearl cotton cushioning pad 100 through the corresponding die-cutting line group. Preferably, the die-cutting line groups include a third line group 3, a fourth line group 4, and a fifth line group 5; this embodiment also uses a square-shaped pearl cotton cushioning pad 100 as an example for further explanation.

[0057] The third line group 3 includes a fifth line set 31 and a sixth line set 32. The fifth line set 31 includes two or more seventh cuts 311 and two eighth cuts 312, with the two eighth cuts 312 arranged in a mirror-symmetrical manner. The seventh cuts 311 and the eighth cuts 312 are distributed at intervals in the same direction, which is perpendicular to a diagonal of the square pearl cotton cushioning pad 100; wherein, the two or more seventh cuts 311 are all located between the two eighth cuts 312.

[0058] The seventh cut 311 includes a fifth horizontal segment 3111, two seventh connecting segments 3112 and two seventh vertical segments 3113. The two seventh connecting segments 3112 are arranged in a mirror symmetry, and the two seventh vertical segments 3113 are arranged in a mirror symmetry, so that a seventh connecting segment 3112 connects between the fifth horizontal segment 3111 and the seventh vertical segment 3113.

[0059] The eighth cut 312 includes an eighth connecting segment 3121, an eighth vertical segment 3122, and a third extension segment 3123. The eighth connecting segment 3121 connects the eighth vertical segment 3122 and the third extension segment 3123. The eighth vertical segment 3122 is located close to the seventh vertical segment 3113 and is parallel to the seventh vertical segment 3113. The third extension segment 3123 is parallel to the edge corresponding to itself, that is, the third extension segment 3123 is parallel to the edge of the edge 103 where it is located.

[0060] The sixth line set 32 ​​is located inside the fifth line set 31. The sixth line set 32 ​​includes two or more ninth cuts 321, which are spaced apart along a direction parallel to the distribution of the seventh cut 311 and the eighth cut 312. Each ninth cut 321 includes a sixth horizontal segment 3211, two ninth connecting segments 3212, and two ninth vertical segments 3213. The two ninth connecting segments 3212 and the two ninth vertical segments 3213 are arranged in a mirror-symmetrical configuration, and the ninth vertical segments 3213 are parallel to the seventh vertical segment 3113. The two ninth connecting segments 3212 and the two ninth vertical segments 3213 correspond one-to-one, such that a ninth connecting segment 3212 connects the sixth horizontal segment 3211 and the ninth vertical segment 3213.

[0061] Furthermore, through the design of the seventh cut 311 and the ninth cut 321, both the seventh cut 311 and the ninth cut 321 are U-shaped. The openings of the seventh cut 311 and the ninth cut 321 face each other and interlock, meaning the seventh vertical segment 3113 is inserted into the opening of the ninth cut 321, and the ninth vertical segment 3213 is inserted into the opening of the seventh cut 311.

[0070] Combination Figure 9By designing the cutting path and arrangement of the third thread group 3, when packaging, cushioning, and supporting the packaged item, at least one edge 103 of the pearl cotton cushioning pad 100 can be pulled. The pulled edge 103, under pressure, forces the third thread group 3 to stretch and unfold, causing it to deform synchronously along the stretching direction, forming a mesh support structure with openwork gaps. This mesh support structure ensures that, on the one hand, the edge 103 maintains a stable connection with the pearl cotton cushioning pad 100 body, preventing the edge 103 from detaching or separating from the pearl cotton cushioning pad 100; on the other hand, the openwork area of ​​the mesh support structure can directly adapt to and accommodate local protrusions or irregular structures of the packaged item, thus eliminating the need for additional material removal from the pearl cotton cushioning pad 100, simplifying the packaging process and improving the convenience and efficiency of packaging operations.

[0071] Combination Figure 10 and Figure 11 A fourth thread group 4 is added to the pearl cotton cushioning pad 100, so that after the edge 103 of the pearl cotton cushioning pad 100 is stretched and unfolded once by the third thread group 3, it can also be stretched and unfolded a second time along the guide of the fourth thread group 4. The secondary stretching and unfolding function given by the fourth thread group 4 can further expand the deformation range and contour adaptation range of the cushioning pad. It can not only meet the more complex packaging needs such as irregular structures and multiple protrusions, but also adapt to more sizes and shapes of packaged items, effectively solving the problem of the single adaptability of traditional cushioning pads, and further improving the practical performance and overall applicability of the pearl cotton cushioning pad 100.

[0072] In addition, the addition of a fifth line group 5 enables the pearl cotton cushioning pad 100 to achieve stepped multi-level stretching and unfolding. This not only significantly expands the stretching and unfolding range of the cushioning pad and further broadens its adaptability, but also allows it to flexibly adapt to more packaging materials of different sizes, shapes and structural characteristics, greatly improving the practicality of the pearl cotton cushioning pad 100 and further expanding its application scenarios and scope of application.

[0073] It should be noted that this embodiment uses a square block (a special rectangular block) as an example for illustration. When the pearl cotton cushioning pad 100 is a rectangular block that is not square, its structural design is similar to the design method illustrated in this embodiment, so it will not be described again here.

[0074] Packaging Structure Examples The packaging structure includes a packaging box and a pearl cotton cushioning pad. The pearl cotton cushioning pad is the same as described in the first or second embodiment above, and it is installed inside the packaging box. By employing the aforementioned pearl cotton cushioning pad, the packaging structure can better package different types of items and is adaptable to various packaging types. Furthermore, there is no need to remove material from the pearl cotton cushioning pad during the packaging process, which helps improve packaging efficiency. Additionally, since the pearl cotton cushioning pad is initially shrunk to its minimum volume, it reduces the space required for storage and transportation, thus lowering transportation costs.

[0075] Packaging Product Examples The packaged product includes the packaged item and the packaging structure described in the above-described packaging structure embodiment. The packaged item is placed on a pearl cotton cushioning pad, which can be stretched and unfolded.
