Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
[0044] The following is combined Figures 1 to 2 The packaging box cut pieces and packaging boxes provided in this utility model embodiment will be described in detail through specific embodiments and application scenarios.
[0045] Firstly, such as Figure 1 and Figure 2 As shown, this embodiment provides a packaging box cut piece, including: side panel assembly 1, top panel assembly 2, bottom panel assembly 3 and partition assembly 4.
[0046] The side panel assembly 1 includes two first side panels 11 and two second side panels 12, which are alternately connected along the length of the packaging box piece. For example, along the length of the packaging box piece, the first side panel 11, the first second side panel 12, the second first side panel 11, and the first second side panel 12 are arranged in sequence.
[0047] The top plate assembly 2 includes two first top plates 21 and two second top plates 22. Each first top plate 21 is connected to a corresponding first side plate 11, and each second top plate 22 is connected to a corresponding second side plate 12.
[0048] The base plate assembly 3 includes two base plates 31, each of which is connected to a corresponding first side plate 11. Along the width direction of the packaging box piece, the base plate 31 and the first top plate 21 are located on both sides of the first side plate 11.
[0049] The partition assembly 4 includes two partitions 41, each of which is connected to a corresponding second side plate 12. Along the width direction of the packaging box piece, the partitions 41 and the second top plate 22 are located on both sides of the second side plate 12.
[0050] The packaging box piece has an unfolded state and a folded state. In the folded state, the two partitions 41 and the two bottom plates 31 together form the bottom surface of the packaging box 100, and the free ends of the two partitions 41 bend and extend from the bottom surface toward the height direction of the packaging box 100 to separate the internal space of the packaging box 100.
[0051] Understandably, the packaging box pieces can be made of corrugated paper or white cardboard and stamped in one piece using a stamping machine. The resulting packaging box pieces are in an unfolded state. These packaging box pieces can be folded to form a three-dimensional packaging box 100, which is used to store milk carton.
[0052] In practical applications, the side panel assembly 1 corresponds to the four sides of the packaging box 100, the top panel assembly 2 corresponds to the upper side of the packaging box 100, the bottom panel assembly 3 corresponds to the lower side of the packaging box 100, and the end of the two partitions 41 connected to the second side panel 12 also corresponds to the lower side of the packaging box 100.
[0053] For the formed packaging box 100, the top panel assembly 2, side panel assembly 1, bottom panel assembly 3, and partition assembly 4 together constitute the box body of the packaging box 100. The free ends of the two partitions 41 are bent inside the packaging box 100 along the height direction, thereby dividing the internal storage space of the packaging box 100. The free ends of the two partitions 41 not only form a partition space but also support the side panel assembly 1, enhancing the overall strength of the packaging box 100. For example, the internal storage space of the packaging box 100 is divided into two independent spaces.
[0054] Furthermore, since the ends of the two partitions 41 connected to the second side plate 12 are located inside the two bottom plates 31, the two bottom plates 31 and the two partitions 41 together form the bottom surface of the packaging box 100. The double-layer bottom surface configuration improves the load-bearing capacity of the packaging box 100. Moreover, when the package is placed inside the packaging box 100, the bottom surface of the package presses against the top surface of the partition 41, and the weight of the package can fix the free end of the partition 41, eliminating the need for additional fixation of the two partitions 41.
[0055] In the actual assembly process, by enclosing the side panel assembly 1 of the packaging box pieces, the first side panel 11 and the second side panel 12, which are separated at both ends, are connected together, thus completing the forming operation of the four sides of the packaging box 100. Then, by connecting the two bottom plates 31 with the two partitions 41 and the end connected to the second side panel 12, the forming operation of the bottom surface of the packaging box 100 is completed. Finally, the free ends of the two partitions 41 are bent toward the height direction of the packaging box 100, so that the free ends of the two partitions 41 are set along the height direction of the packaging box 100, and the internal space is divided inside the packaging box 100 based on the free ends of the two partitions 41.
[0056] The planar packaging box cut piece shown in this embodiment can be folded to form a three-dimensional packaging box 100. The partition 41 can be bent to naturally form a space, so that the milk carton inside the box can be separated by the free ends of the two partitions 41. This realizes the design of separating the stored carton through the structure of the packaging box 100 itself. By setting the partition assembly 4 to serve as both the bottom surface of the packaging box 100 and the isolation structure of the internal space of the packaging box 100, the partition assembly 4 in this embodiment integrates the dual functions of bottom support and internal pad, eliminating the need for additional pads and the step of inserting them into the packaging box 100.
[0057] Compared to the existing design that uses a separate pad inside the packaging box 100 to isolate the storage space inside the packaging box 100, the packaging box piece shown in this embodiment can be integrally formed by stamping. While the packaging box piece is folded to form the packaging box 100, the storage space inside the packaging box 100 can be separated by the partition 41 built into the packaging box 100. This design not only has low processing costs and simplifies the assembly process of the packaging box 100 and the pad, thereby reducing the packaging cost of the package, but also ensures the packaging efficiency of the package to a certain extent.
[0058] like Figure 1 As shown, each partition 41 in this embodiment includes a bottom plate 411 and a partition plate 412. A first crease 413 along the length direction is formed between the bottom plate 411 and the partition plate 412; in the folded state, both bottom plates 411 are fitted to both bottom plates 31, and both partition plates 412 are fitted to each other.
[0059] Understandably, to facilitate the folding of the packaging box pieces, a first crease 413 is provided between the bottom plate 411 and the dividing plate. When folding the packaging box 100, the bending between the bottom plate 411 and the dividing plate 412 can be completed quickly through the first crease 413. The two bottom plates 411 extend along the bottom surface of the packaging box 100, and both bottom plates 411 are attached to the two base plates 31, together forming the bottom surface of the packaging box 100. The two base plates 31 are located on the side of the bottom plate 411 opposite to the dividing plate 412.
[0060] At the same time, the two partition plates 412 are attached together, which enhances the structural strength of the partition plates 412 and divides the storage space inside the packaging box 100 into two parts. The attachment of the partition plates 412 also connects the two bottom plates 411 and the two partition plates 412 into a whole, which enhances the strength of the partition 41.
[0061] To improve the convenience of packing, both partition plates 412 in this embodiment are bent at 90° to the corresponding bottom plate 411, that is, the partition plates 412 and the bottom plate 411 are set perpendicularly, which is beneficial for packing.
[0062] Similarly, creases are provided between the top plate assembly 2 and the side plate assembly 1, between the side plate assembly 1 and the bottom plate 31, between the side plate assembly 1 and the partition 41, and between the first side plate 11 and the second side plate 12, and between the first top plate 21 and the second top plate 22.
[0063] like Figure 1 As shown, along the width direction, the length of the partition plate 412 in this embodiment is equal to the length of the first side plate 11.
[0064] Understandably, after folding the packaging paper into a packaging box 100, the two interlocking partition plates 412 are located inside the two first side plates 11. Following the width direction of the packaging paper, the partition plates 412 are folded along their length direction to align with the height direction of the packaging box 100, and the first side plates 11 are also folded along their length direction to align with the height direction of the packaging box 100. In the folded state, the height of the partition plates 412 relative to the height of the first side plates 11 reflects the degree to which the partition plates 412 divide the internal storage space of the packaging box 100. In this embodiment, the height of the partition plates 412 is equal to the height of the first side plates 11, meaning the partition plates 412 and the first side plates 11 are flush, thus completely dividing the internal storage space of the packaging box 100 into two spaces, preventing the two spaces from being connected, which would be detrimental to the placement of the package.
[0065] like Figure 1 As shown, each partition 41 in this embodiment is provided with a notch 414, which extends along the width direction, and the notches 414 of the two partitions 41 are arranged on the same side along the length direction.
[0066] Understandably, in practical applications, in order to omit the process of connecting the side panel assembly 1 and the bottom panel assembly 3 and the partition assembly 4 during packaging, the packaging box pieces are usually not in an unfolded state when they leave the factory. Instead, they are pre-formed into a pre-shaped state before leaving the factory. The pre-shaped state is between the unfolded state and the folded state.
[0067] In the pre-formed state of the packaging box pieces, the side panel assembly 1 of the packaging box pieces is fully connected, and the two bottom plates 31 and the two partitions 41 are also connected. In actual use, the separated first side plate 11 and second side plate 12 can be glued together with glue or double-sided tape, and the two bottom plates 31 and the two partitions 41 can be glued to the bottom surface. To facilitate the transportation of the pre-formed packaging box 100, a notch 414 is provided on the partition 41. When the frame formed by the assembled packaging box pieces is pressed, the notch 414 can provide clearance space, so that the frame of the packaging box pieces becomes a flat stacked state, which is convenient for transport and storage. Moreover, when packing the package, it is only necessary to open the pre-formed packaging box pieces and bend the free end of the partition 41 to complete the folding of the packaging box 100, without the need for manual gluing, which improves the efficiency of packing.
[0068] Because the first side plate 11 and the second side plate 12 are pressed onto a single plane when the frame of the packaging box piece deforms, both partitions 41 need to have notches 414. Furthermore, based on the process of the bottom surface of the packaging box piece frame changing from a cuboid to a parallelogram and finally to a straight line, the two notches 414 need to be located on the diagonal of the rectangle. Therefore, the notches 414 of the two partitions 41 need to be located on the same side along the length direction to ensure that they are located on the diagonal of the bottom surface of the rectangle after the frame is formed.
[0069] like Figure 1 As shown, the notch 414 in this embodiment includes a triangular notch 4141 and a strip notch 4142. The triangular notch 4141 is located at one end of the bottom plate 411 facing the second side plate 12; the strip notch 4142 is connected to the triangular notch 4141, and the strip notch 4142 is located in the area where the bottom plate 411 and the partition plate 412 are located.
[0070] Understandably, in order to allow the packaging box piece to switch freely between the unfolded state, the pre-formed state, and the folded state, the notch 414 in this embodiment includes a triangular notch 4141 and a strip notch 4142. The triangular notch 4141 is located at the connection between the partition 41 and the second side plate 12. The inclined side formed by the triangular notch 4141 is more conducive to the change of the rectangle on the bottom surface towards a parallelogram. The strip notch 4142 is located next to the triangular notch 4141, closer to the middle of the partition 41 along the width direction. When the packaging box piece is folded into the packaging box 100, the strip notch 4142 is located at the connection between the bottom plate 411 and the partition plate 412, which is more conducive to the bending of the bottom plate 411 and the partition plate 412, and the shape is more regular after bending.
[0071] like Figure 1As shown, in this embodiment, one of the two ends of the bottom plate 31 on the side away from the first side plate 11 is provided with a chamfer 311, and the other end has an adhesive layer 312. The adhesive layer 312 is used to be pasted to the bottom surface of the packaging box 100. The two adhesive layers 312 are located on the same side of the two bottom plates 31 along the length direction.
[0072] Understandably, to accommodate the pre-formed state of the packaging box pieces, one end of the base plate 31 has a chamfer 311, and the other end has an adhesive layer 312. The adhesive layer 312 adheres one end of the base plate 31 to the bottom plate 411. When the frame formed by the enclosing side panel assembly 1 is pressed into a pre-formed state, the rectangular bottom surface deforms along the diagonal of the end with the chamfer 311. The chamfer 311 provides clearance for the deformation of the rectangular bottom surface, and the adhesive layer 312 ensures the connection between the side panel assembly 1 and the bottom surface when the frame is pressed into a flat stacked state.
[0073] It should be noted that, in order to ensure that the two partition plates 412 can separate when the frame is deformed, the adhesive layer 312 can only be adhered to one bottom plate 411, and not both bottom plates 411.
[0074] Furthermore, since the adhesive layer 312 is located on the same side of the two base plates 31, and the chamfer 311 is also located on the same side of the two base plates 31, the two chamfers 311 are on the same diagonal of the bottom surface of the rectangle, which is beneficial to the deformation of the planar stacked shape in the preformed state.
[0075] like Figure 1 and Figure 2 As shown, in this embodiment, the length of the first top plate 21 along the width direction is equal to half the length of the second top plate 22 along the length direction.
[0076] Understandably, after the packaging box 100 is packed, the two first top plates 21 and the two second top plates 22 in the top plate assembly 2 are folded toward the internal storage space of the packaging box 100, and the first top plates 21 and the second top plates 22 form the top surface of the packaging box 100, sealing the internal storage space.
[0077] The two second top plates 22 can be bent first, and then the two first top plates 21 can be bent, with the first top plates 21 covering the outside of the second top plates 22. In order to completely seal the top surface of the packaging box 100, the length of the first top plate 21 in this embodiment is set to half the length of the second top plate 22, that is, the combined length of the two first top plates 21 after bending is equal to that of the second top plate 22. The ends of the two first top plates 21 abut against each other to form a closed plane, which is beneficial to the aesthetics of the packaging box 100.
[0078] like Figure 1As shown, in this embodiment, a clearance joint 23 is provided between adjacent first top plate 21 and second top plate 22. The clearance joint 23 extends along the width direction, and the width of the clearance joint 23 gradually increases in the direction away from the side plate assembly 1.
[0079] Understandably, since the first side plate 11 and the second side plate 12 are folded along the creases, the first top plate 21 relative to the first side plate 11 and the second top plate 22 relative to the second side plate 12 also need to be folded along the creases, the first top plate 21 and the second top plate 22 are in a separated state. In order to prevent the first top plate 21 and the second top plate 22 from sticking together, this embodiment provides an avoidance seam 23 between the first top plate 21 and the second top plate 22. Furthermore, the width of the avoidance seam 23 gradually increases towards the outer side of the first top plate 21 and the second top plate 22, making it easier to bend the first top plate 21 and the second top plate 22 relative to the side plate assembly 1, which is beneficial to improving the work efficiency of the operator.
[0080] like Figure 1 As shown, the packaging box cut piece in this embodiment also includes a connecting piece 5. The connecting piece 5 is disposed at one end of the side panel assembly 1 and connected to the end of the first side panel 11 that is opposite to the second side panel 12.
[0081] When the packaging box pieces are in a folded state, the connecting piece 5 is used to fix the first side plate 11 and the second side plate 12 at both ends of the side plate assembly 1.
[0082] Understandably, when the side panel assembly 1 is assembled to form a frame, the connecting piece 5 can extend into the inside of the second side panel 12. Applying glue or double-sided tape to the connecting piece 5 allows the first side panel 11 and the second side panel 12 to be securely connected.
[0083] Secondly, such as Figure 1 and Figure 2 As shown, this embodiment provides a packaging box 100, which is formed by folding the packaging box pieces as described above.
[0084] Specifically, since the packaging box 100 includes packaging box pieces, and the specific structure of the packaging box pieces refers to the above embodiments, the packaging box 100 shown in this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above embodiments, which will not be described in detail here.
[0085] Understandably, if the packaging box pieces are made of corrugated paper, the packaging box 100 can be a corrugated cardboard box.
[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
