Description

Technical Field

[0001] This application belongs to the field of packaging boxes, and particularly relates to a folding packaging box. Background Technology

[0002] Currently, China experiences a large volume of various products, leading to a high demand for transport cartons. However, traditional paper transport cartons suffer from drawbacks such as wrinkling, poor water resistance, weak impact resistance, susceptibility to punctures by sharp objects, limited load-bearing capacity, and insufficient product protection. These shortcomings prevent them from meeting the needs of certain transport packaging markets, such as the transport packaging of unpackaged wine. Ordinary unpackaged wine transport cartons are frequently wrapped with various types of tape for transport safety, and large amounts of EPE (Expandable Polyethylene), foam, bubble wrap, and other cushioning materials are placed between the cartons and bottles, and between the bottles themselves, to prevent collisions during transport or handling. Used cartons and fillers are often discarded directly, resulting in low recycling rates, high costs, and environmental harm.

[0047] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0048] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0049] Existing traditional paper shipping box packaging processes require extensive tape wrapping and sealing, resulting in the placement of large amounts of filler material inside the boxes, which is then discarded as waste. Furthermore, paper packaging boxes have low recycling rates, are costly, and are environmentally unfriendly. To address these technical problems, embodiments of this application provide a foldable packaging box. The foldable packaging box provided in this application embodiment is described below.

[0050] Please refer to Figure 1 and Figure 2 This application provides a folding packaging box 10, which includes a top cover 1, a bottom box 2, and a folding assembly 3. The bottom box 2 has a first receiving cavity 21. The folding assembly 3 includes a plurality of panels 31, which are rotatably connected to the bottom box 2. The plurality of panels 31 have a folded state and an unfolded state. In the folded state, the plurality of panels 31 are stacked in the first receiving cavity 21, and the top cover 1 is used to cover the first receiving cavity 21. When the plurality of panels 31 are rotated relative to the bottom box 2 to the unfolded state, the plurality of panels 31 surround to form a second receiving cavity 31a that communicates with the first receiving cavity 21, and the top cover 1 is used to cover the second receiving cavity 31a.

[0051] like Figure 1 In the embodiment shown, when transporting items, each panel 31 in the folding assembly 3 of the folding box 10 rotates relative to the bottom box 2 to an unfolded state, so that each panel 31 can surround the second receiving cavity 31a that forms a first receiving cavity 21, thereby increasing the volume of items that the folding box 10 can hold.

[0052] like Figure 2 In the embodiment shown, when the folding packaging box 10 is recycled, each panel 31 in the folding assembly 3 rotates relative to the bottom box 2 so that each panel 31 can be housed in the bottom box 2, and the top cover 1 covers the bottom box 2, reducing the volume of the folding packaging box 10, thereby facilitating the recycling of the folding packaging box 10 and reducing recycling and transportation costs.

[0053] Optionally, the folding packaging box 10 is made of materials such as PP (Polypropylene) that are pressure-resistant, shock-resistant, and waterproof. Compared with traditional paper boxes, the folding packaging box 10 has strong resistance to impact, high and low temperatures and humidity, is shock-resistant and pressure-resistant, has better load-bearing capacity, can ensure safe and stable transportation, and is more conducive to recycling and reuse, reducing the cost of single use.

[0054] The panel 31 and the base box 2 can be rotatably connected in several ways. For example, a pin can be used to achieve this connection. Of course, pins can also be used to achieve rotatable connections in other parts. Please refer to [reference needed]. Figure 3 Optionally, the pin 4 includes a pin post 42 and a pin locking position 41. The two are rotatably connected and have rotatable connection positions. After the pin post 42 is inserted into the rotatable connection position of each component that needs to be rotatably connected, the pin locking position 41 is locked with the rotatable connection position and cannot be pulled out. The rotatably connected component rotates around the pin 4.

[0055] In this embodiment, each panel 31 of the folding assembly 3 is rotatably connected to the bottom box 2, allowing the folding assembly 3 to be folded and housed in the first receiving cavity 21. This results in a smaller volume for the folding packaging box 10, facilitating transportation and reducing recycling and transportation costs. Furthermore, the multiple panels 31 of the folding assembly 3 can rotate relative to the bottom box 2, allowing each panel 31 to surround a second receiving cavity 31a that connects to the first receiving cavity 21, thereby increasing the volume of items that the folding packaging box 10 can hold.

[0056] The foldable packaging box 10 is recyclable and reusable. Its small size when folded reduces recycling and transportation costs, thereby lowering the cost of each use of the foldable packaging box 10.

[0057] Please refer to Figure 4 In some embodiments, the plurality of panels 31 include at least one combination plate 32, the top cover plate 1 and the end of the combination plate 32 away from the bottom box 2 are rotatably connected, and the combination plate 32 includes 2n sub-plates 321 that are rotatably connected in sequence along the first direction X; in the folded state, the plurality of sub-plates 321 are stacked in the first receiving cavity 21; in the unfolded state, the plurality of sub-plates 321 unfold to form a plane defining the second receiving cavity 31a, where n is a positive integer.

[0058] The assembly plate 32 is composed of 2n sub-plates 321 that are sequentially rotatably connected, allowing the included angle between adjacent sub-plates 321 to be adjustable. In the unfolded state, the multiple sub-plates 321 can be unfolded to form a flat plate. When the folding assembly 3 is folded, the sub-plate 321 closest to the bottom box 2 rotates into the bottom box 2 first, and the sub-plates 321 rotatably connected to it rotate and fold onto it, and so on, until the top cover plate 1 can be placed on the multiple stacked sub-plates 321. Those skilled in the art will understand that in order to achieve the stacking of multiple sub-plates 321, the folding directions of two adjacent sub-plates 321 are opposite. Since the number of sub-plates 321 is even, after all the sub-plates 321 are folded, the closing direction of the top cover plate 1 is the same as the closing direction in the unfolded state, so that the top cover plate 1 can cover the second receiving cavity 31a.

[0059] Please refer to the reference. Figure 4 and Figure 5 In some embodiments, the folding packaging box 10 further includes a first latch 5, the bottom box 2 includes a bottom wall 22 and a side wall 23, the side wall 23 forms a first receiving cavity 21 around the bottom wall 22, the bottom box 2 includes a first latch position 231 disposed on the side wall 23, the combination plate 32 includes a second latch position 322 disposed on the sub-plate, and the top cover plate 1 includes a third latch position 11 disposed on the side where the top cover plate 1 connects to the combination plate 32. In the unfolded state, the first latch 5 engages with the first latch position 231 and the third latch position 11. In the folded state, the first latch 5 engages with the first latch position 231 and the second latch position 322.

[0060] In the unfolded state, the first latch 5 engages with the bottom box 2 and the combination plate 32, fixing the relative position of the combination plate 32 and the bottom box 2. This prevents the combination plate 32 and the bottom box 2 from rotating relative to each other when the folded packaging box 10 is subjected to large compressive force, thereby enhancing the stability of the combination plate 32 in the unfolded state. In the folded state, the combination plate 32 is folded and housed in the first receiving cavity 21. After the top cover plate 1 is closed, the first latch 5 engages with the bottom box 2 and the top cover plate 1, fixing the relative position of the top cover plate 1 and the bottom box 2, making the top cover plate 1 and the bottom box 2 close more tightly.

[0061] Please refer to the reference. Figure 6Optionally, the first latch 5 includes a latching member 51 and a latching member accessory 52. ​​The latching member 51 is rotatably connected to the first latching position 11. The latching member 51 is provided with a first rotating connecting shaft 511 connected to the first latching position 11 and a rotating connecting position 512 connected to the latching member accessory 52. ​​The latching member accessory 52 is provided with a second rotating connecting shaft 521, which is located at the rotating connecting position 512 of the latching member, so that the latching member 51 and the latching member accessory 52 are rotatably connected. The latching member accessory 52 is also provided with a buckle 522. In the unfolded state, the buckle 522 engages with the second latching position 322 to lock the combined plate 32. In the folded state, the buckle 522 engages with the third latching position 231 to lock the top cover plate 1.

[0062] Please refer to Figure 7 and Figure 8 In some embodiments, the plurality of panels 31 include a first panel 33, a second panel 34, and a third panel 35 that are rotatably connected to the side wall 23. In the unfolded state, the second panel 34 and the third panel 35 are spaced apart along the second direction Y, and the first panel 33 and the combined panel 32 are spaced apart along the third direction Z. In the folded state, the second panel 34 and the third panel 35 are respectively arranged opposite to the bottom wall 22 along the first direction X, and the first panel 33 and the plurality of sub-panels 321 stacked together are respectively located on the side of the second panel 34 and the third panel 35 away from the bottom wall 22.

[0063] In some embodiments, the number of panels 31 is four, and the bottom box 2 is rectangular. The four panels, the top cover 1, and the bottom box 2 are combined to form a rectangular folding packaging box 10. Compared with other shapes, the rectangular shape is regular and has a larger space utilization rate during transportation. When switching from the unfolded state to the folded state, the opposite second panel 34 and third panel 35 can be folded into the first receiving cavity 21 first, and then the first panel 33 and the combination plate 32 can be folded into the first receiving cavity 21. After the combination plate 32 is folded, it is placed above the second panel 34 and / or the third panel 35 so that the top cover 1 connected to the combination plate 32 can be closed normally.

[0064] In some embodiments, the plurality of sub-plates 321 include a first sub-plate 3211 and a second sub-plate 3212. The sidewall 23, the first sub-plate 3211, and the second sub-plate 3212 are rotatably connected in sequence. In the folded state, the first sub-plate 3211, the second sub-plate 3212, and the top cover plate 1 are stacked in sequence along the first direction X. When switching from the unfolded state to the folded state, the first sub-plate 3211 is folded along the connection with the sidewall 23 toward the central axis closer to the first receiving cavity 21, the second sub-plate 3212 is folded along the connection with the first sub-plate 3211 toward the central axis away from the first receiving cavity 21, and the top cover plate 1 is folded along the connection with the second sub-plate 3212 toward the central axis closer to the first receiving cavity 21 and covers it.

[0065] Please refer to Figure 9 In some embodiments, the top cover 1 has multiple inserts 12 on the side near the bottom box 2, and the folding assembly 3 also includes insertion holes 36 on the panel 31; in the unfolded state, the inserts 12 are inserted into the insertion holes 36. After the cover 1 is closed on the folding assembly 3, the top cover 1 and the folding assembly 3 are relatively positioned by the inserts 12. The insertion holes 36 can be provided on one of the panels or on multiple panels. After the top cover 1 is closed on the folding assembly 3, the inserts 12 are inserted into the insertion holes 36, making the folded packaging box 10 more stable and with better sealing. Optionally, there are 6 insertion holes 36 and 6 inserts 12, with the 6 inserts 12 evenly distributed at the three ends of the top cover 1 that are not directly connected to the folding assembly 3, and the insertion holes 36 are correspondingly provided on three different panels 31.

[0066] Please refer to the reference. Figure 10 To ensure that the items inside the folding packaging box 10 are more stable during transportation, in some embodiments, the folding packaging box 10 also includes a folding component 6. The folding component 6 includes a fixing part 61 spaced apart from the bottom wall 22. The fixing part 61 includes a plurality of first fixing positions 611 for fixing the transported items. In the unfolded state, the fixing part 61 is located in the second receiving cavity 31a. Optionally, the fixing part is engaged in the second receiving cavity 31a by a locking plate to prevent it from falling into the bottom box 2. In the folded state, the folding component 6 is received in the first receiving cavity 21.

[0067] The number and shape of the first fixing positions 611 are set according to the number and shape of the transported items. For example, in a folding packaging box 10 used to transport unpackaged liquor, the box contains 6 bottles of unpackaged liquor with a circular cross-sectional shape. The shape of the first fixing positions 611 is also set to be circular. Multiple first fixing positions 611 can be arranged on both sides of the fixing part 61, with 3 positions in each row, for a total of 6 first fixing positions 611, which are used to fix the unpackaged liquor. In the folded state, the folding part 6 is housed in the first receiving cavity 21 and can be recycled and reused together with the other parts of the folding packaging box 10.

[0068] Please refer to the reference. Figure 11 In some embodiments, the bottom box 2 further includes a second fixing position 24 disposed between the bottom wall 22 and the fixing part 61, and the second fixing position 24 is configured in a one-to-one correspondence with the first fixing position 611.

[0069] The corresponding first fixing position 611 and second fixing position 24 can simultaneously secure the transported items, making the securing of the transported items more reliable. The second fixing position 24 can be provided with a reinforcing rib 241 protruding from its inner wall, gradually widening along the direction from the second fixing position 24 towards the first fixing position 611. Taking a bare bottle of liquor as an example, when the bottle is placed in the second fixing position 24, because the reinforcing rib 241 is narrower at the top and wider at the bottom, it becomes increasingly tighter when the bottle is placed, locking it in place without it reaching the bottom. This provides some cushioning for the bottle when the folding packaging box 10 is dropped, while also meeting the tolerances introduced during the bottle's manufacturing process.

[0070] In some embodiments, the folding member 6 further includes pins 62 disposed at both ends of the fixing part 61. One end of the pin 62 is rotatably connected to the fixing part 61. In the folded state, the pin 62 is folded toward the fixing part 61. In the unfolded state, the pin 62 is set at an angle to the fixing part 61. The end of the pin 62 away from the fixing part 61 is detachably connected to the bottom box 2.

[0071] In the folded state, the pin 62 and the fixing part 61 are folded together, so that the folded part 6 can be housed in the bottom box 2. In the unfolded state, the end of the pin 62 away from the fixing part 61 is detachably connected to the bottom box 2 so that the pin 62 can support the fixing part 61 in the second receiving cavity 31a.

[0072] In some embodiments, the folding member 6 includes a groove 612, which is located on the side of the fixing part 61 near the top cover plate 1 and / or away from the top cover plate 1. In the folded state, the prongs 62 are placed in the groove 612. In the folded state, the two prongs 62 are folded and stacked with the fixing part 61.
