Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a packaging box cut piece and a packaging box. Background Technology

[0002] Currently, beverages such as milk and juice are packaged in bags, and to facilitate bulk storage and transportation of these bags, they are usually stored in boxes.

[0003] However, in practical applications, it has been found that to ensure orderly placement of packages, spacers are usually placed inside the packaging box to separate multiple packages. During packaging box assembly, not only is manual or automated sealing of the bottom of the box with tape necessary, but the process of folding and placing the spacers also increases packaging costs and, to some extent, affects the efficiency of package packing. Utility Model Content

[0004] This utility model provides a packaging box cut-out piece and a packaging box to solve the problem in the prior art that the packaging box is difficult to design to separate the stored packages through its own structure.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, this utility model provides a packaging box cut piece, comprising:

[0007] The side panel assembly includes two first side panels and two second side panels, which are alternately connected along the length of the packaging box piece.

[0008] The top plate assembly includes two first top plates and two second top plates, each first top plate being connected to a corresponding first side plate, and each second top plate being connected to a corresponding second side plate;

[0009] The first base plate assembly includes two first base plates, each of which is connected to a corresponding first side plate. Along the width direction of the packaging box piece, the first base plate and the first top plate are located on both sides of the first side plate.

[0010] The second base plate assembly includes two second base plates, each of which is connected to a corresponding second side plate. Along the width direction of the packaging box piece, the second base plate and the second top plate are located on both sides of the second side plate.

[0011] The packaging box panel is in a folded state. In this folded state, the two first base plates and the two second base plates together form the bottom surface of the packaging box. The free ends of each first base plate and each second base plate are bent and extended from the bottom surface toward the height direction of the packaging box. The free ends of the two first base plates are fitted together, and the free ends of the first base plates and the free ends of the second base plates are interlocked inside the packaging box to divide the internal space of the packaging box into multiple independent spaces.

[0012] According to the packaging box cut piece provided by this utility model, the first base plate includes a first plate body and a tab;

[0013] The first plate and the latch are arranged along the width direction, the first plate is connected to the first side plate, and a first crease along the length direction is formed between the first plate and the latch.

[0014] The second base plate includes a second plate body and a snap-fit ​​part;

[0015] The second plate and the snap-fit ​​portion are arranged along the width direction. The second plate is connected to the second side plate. A second crease along the length direction is formed between the second side plate and the snap-fit ​​portion. The snap-fit ​​portion has a slot.

[0016] In the folded state, the latch is inserted into the slot.

[0017] According to the present invention, a packaging box cut piece is provided, wherein the end of the tab opposite to the first plate has a shoulder;

[0018] When the latch is inserted into the slot, the shoulder abuts against the edge of the slot to limit the latch.

[0019] According to the present invention, in a packaging box cut piece, the width of the portion of the tab inserted into the slot gradually decreases along the length direction toward the connection point between the first base plate and the second base plate.

[0020] Along the width direction toward the position opposite to the connection between the second base plate and the second side plate, the width of the slot gradually decreases along the width direction.

[0021] According to the present invention, the length of the first plate along the width direction is half the length of the second side plate along the length direction, so that the two tabs are fitted together when the packaging box is in a folded state.

[0022] According to the present invention, each of the second base plates is provided with a notch, the notch extends along the width direction, and the notches of the two second base plates are arranged on the same side along the length direction.

[0023] According to the present invention, a packaging box cut piece is provided, wherein one of the two ends of the first plate body on the side away from the first side plate is provided with a chamfer, and the other end is provided with an adhesive layer, the adhesive layer being used to adhere to the bottom surface of the packaging box;

[0024] Along the length direction, the two adhesive layers are located on the same side of the two first plates.

[0025] According to the present invention, the length of the first top plate along the width direction is equal to half the length of the second top plate along the length direction.

[0026] The packaging box cut piece provided by this utility model further includes: a connecting piece;

[0027] The connecting piece is disposed at one end of the side plate assembly and is connected to the end of the first side plate that is opposite to the second side plate.

[0028] When the packaging box piece is in a folded state, the connecting piece is used to fix the first side plate and the second side plate at both ends of the side plate assembly.

[0029] Secondly, this utility model provides a packaging box, which is formed by folding the packaging box pieces as described above.

[0030] The packaging box and packaging box provided by this utility model, through folding to form a three-dimensional packaging box, can naturally form multiple independent partition spaces by bending the first and second base plates. The milk carton inside the box is isolated by the interlocking of the free ends of the first and second base plates. This achieves a design that separates the stored carton through the packaging box's own structure. By setting the first and second base plates to serve as both the bottom surface of the packaging box and the isolation structure of the internal space, the first and second base plates integrate the dual functions of bottom support and internal padding, eliminating the need for additional padding and the step of inserting the packaging box. Furthermore, the interlocking of the free ends of the first and second base plates can form multiple independent spaces within the packaging box, facilitating the classified storage of multiple cartons and expanding the versatility of the packaging box's storage capacity.

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.

[0046] The following is combined Figures 1 to 3The packaging box cut pieces and packaging boxes provided in this utility model embodiment will be described in detail through specific embodiments and application scenarios.

[0047] Firstly, such as Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a packaging box cut piece, including: a side panel assembly 1, a top panel assembly 2, a first bottom panel assembly 3, and a second bottom panel assembly 4.

[0048] 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.

[0049] 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.

[0050] The first base plate assembly 3 includes two first 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 first base plate 31 and the first top plate 21 are located on both sides of the first side plate 11.

[0051] The second base plate assembly 4 includes two second base plates 41, each of which is connected to a corresponding second side plate 12. Along the width direction of the packaging box piece, the second base plate 41 and the second top plate 22 are located on both sides of the second side plate 12.

[0052] The packaging box cut piece has an unfolded state and a folded state. In the folded state, the two first base plates 31 and the two second base plates 41 together form the bottom surface of the packaging box 100. The free ends of each first base plate 31 and each second base plate 41 are bent and extended from the bottom surface toward the height direction of the packaging box 100. The free ends of the two first base plates 31 are fitted together, and the free ends of the first base plates 31 and the free ends of the second base plates 41 are interlocked inside the packaging box 100 to divide the internal space of the packaging box 100 into multiple independent spaces.

[0053] Understandably, the packaging box cut pieces can be made of corrugated paper or white cardboard and stamped in one piece using a stamping machine. The resulting packaging box cut pieces are flat. These packaging box cut pieces can be folded to form a three-dimensional packaging box 100, which is used to store milk carton.

[0054] 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, and the first bottom panel assembly 3 and the second bottom panel assembly 4 correspond to the lower side of the packaging box 100.

[0055] For the formed packaging box 100, the top plate assembly 2, the side plate assembly 1, the first bottom plate assembly 3, and the second bottom plate assembly 4 together constitute the box body of the packaging box 100. The free ends of the first bottom plate 31 and the second bottom plate 41 are bent inside the packaging box 100 and set along the height direction of the packaging box 100. The free ends of the two first bottom plates 31 fit together, dividing the internal space of the packaging box 100 into two parts. Furthermore, the free ends of the second bottom plate 41 are inserted into the free ends of the first bottom plate 31. Since the first bottom plate 31 and the second bottom plate 41 intersect, the two second bottom plates 41 further divide the internal space into two parts, making the internal space divided into multiple independent spaces. The free ends of the first bottom plate 31 and the free ends of the second bottom plate 41 can not only form dividing spaces, but also support the side plate assembly 1, enhancing the overall strength of the packaging box 100.

[0056] Furthermore, since the end of the first base plate 31 connected to the first side plate 11 and the end of the second base plate 41 connected to the second side plate 12 are stacked and formed on 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 first base plate 31 or the second base plate 41, and the weight of the package can fix the free end of the first base plate 31 or the free end of the second base plate 41, eliminating the need for additional fixing of the first base plate 31 or the second base plate 41.

[0057] 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 first bottom plate 31 to the end connected to the first side panel 11, the forming operation of the bottom surface of the packaging box 100 is completed. Finally, the free ends of the first bottom plate 31 and the second bottom plate 41 are bent toward the height direction of the packaging box 100, so that the free ends of the first bottom plate 31 and the second bottom plate 41 are both set along the height direction of the packaging box 100, and the free ends of the two first bottom plates 31 are attached together and the free ends of the first bottom plate 31 and the second bottom plate 41 are interlocked. Inside the packaging box 100, multiple independent spaces are formed based on the free ends of the first bottom plate 31 and the second bottom plate 41.

[0058] For example, when the packaging box 100 is folded, along the length direction, the free ends of the two first base plates 31 are attached together, the free end of the first first base plate 31 is inserted into the free end of the second second base plate 41, and the free end of the second first base plate 31 is inserted into the free end of the first second base plate 41.

[0059] Specifically, the insertion and engagement of the free ends of the first base plate 31 and the second base plate 41 can be achieved by providing insertion ports at the free ends of the first base plate 31 and the second base plate 41 respectively, and then inserting the two insertion ports into each other. Alternatively, the insertion and engagement of the free ends of the first base plate 31 and the second base plate 41 can be achieved through a locking tongue and a locking hole.

[0060] The planar packaging box shown in this embodiment can be folded to form a three-dimensional packaging box 100. Multiple independent partitions can be naturally formed by bending the first base plate 31 and the second base plate 41. The milk carton inside the box is isolated by the interlocking of the free ends of the first base plate 31 and the second base plate 41. This achieves a separation design of the stored carton through the structure of the packaging box 100 itself. By setting the first base plate 31 and the second base plate 41 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 first base plate 31 and the second base plate 41 in this embodiment integrate the dual functions of bottom support and internal padding, eliminating the need for additional padding and insertion into the packaging box 100. Furthermore, the interlocking of the free ends of the first base plate 31 and the second base plate 41 can form multiple independent spaces within the internal space of the packaging box 100, facilitating the classified storage of multiple cartons and expanding the storage capacity of the packaging box 100.

[0061] Compared to existing designs that use spacers to isolate the storage space within the packaging box 100, the packaging box cut pieces shown in this embodiment can be integrally formed using a stamping process. While the packaging box 100 is formed by folding the packaging box cut pieces, the storage space within the packaging box 100 can be separated by the first base plate 31 and the second base plate 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 spacers, thereby reducing the packaging cost of the package, but also ensures the packaging efficiency of the package to a certain extent.

[0062] like Figure 1 As shown, the first base plate 31 in this embodiment includes a first plate body 311 and a latch 312.

[0063] The first plate 311 and the latch 312 are arranged along the width direction. The first plate 311 is connected to the first side plate 11. A first crease 313 along the length direction is formed between the first plate 311 and the latch 312.

[0064] The second base plate 41 includes a second plate body 411 and a snap-fit ​​part 412.

[0065] The second plate 411 and the snap-fit ​​part 412 are arranged along the width direction. The second plate 411 is connected to the second side plate 12. A second crease 413 along the length direction is formed between the second side plate 12 and the snap-fit ​​part 412. The snap-fit ​​part 412 has a slot 4121.

[0066] In the folded state, the latch 312 is inserted into the slot 4121.

[0067] Understandably, in order to facilitate the folding operation of the packaging box pieces, a first crease 313 is provided between the first plate 311 and the latch 312, and a second crease 413 is provided between the second plate 411 and the latching part 412. When folding the packaging box 100, the bending between the first plate 311 and the latch 312 can be completed quickly through the first crease 313. Similarly, the bending between the second plate 411 and the latching part 412 can be completed quickly through the second crease 413.

[0068] The latch 312 can extend into the slot 4121 provided on the latching part 412, thereby completing the insertion and engagement of the latch 312 and the latching part 412. Since both the latch 312 and the slot 4121 can be provided on the first base plate 31 and the second base plate 41, the connection between the first base plate 31 and the second base plate 41 can be easily achieved without additional structures, which is beneficial to improving the efficiency of assembling the packaging box 100.

[0069] Two first plates 311 extend along the bottom surface of the packaging box 100, and both first plates 311 are attached to two second plates 411 to form the bottom surface of the packaging box 100.

[0070] To improve the convenience of packing the package, both latching parts 412 in this embodiment are engaged with the corresponding latching tongue 312 at a 90° angle, that is, the latching tongue 312 and the latching part 412 are set perpendicularly, which is beneficial for packing the package.

[0071] Similarly, creases are provided on the top plate assembly 2 and the side plate assembly 1, the first side plate 11 and the first bottom plate 31, the second side plate 12 and the second bottom plate 41, as well as 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.

[0072] like Figure 1 As shown, the end of the latch 312 opposite to the first plate 311 in this embodiment has a shoulder 3121.

[0073] When the latch 312 is inserted into the slot 4121, the shoulder 3121 and the edge of the slot 4121 abut against each other to limit the latch 312.

[0074] Understandably, in order to limit the insertion depth of the latch 312 in the slot 4121, this embodiment provides a shoulder 3121 at the end of the latch 312 facing away from the first plate 311. Along the width direction of the packaging box piece, the length of the shoulder 3121 exceeds the length of the latch 312. When the latch 312 extends into and moves toward the slot 4121, at the shoulder 3121, the length of the shoulder 3121 that exceeds the slot 4121 abuts against the edge of the slot 4121. The movement of the latch 312 further extending into the slot 4121 is restricted, so that during the assembly of the packaging box 100, the latch 312 will not be over-inserted into the slot 4121, causing deformation of the latching structure.

[0075] like Figure 1 As shown, along the length direction toward the connection point between the first base plate 31 and the second base plate 41, the width of the portion of the latch 312 inserted into the slot 4121 in this embodiment gradually decreases.

[0076] Along the width direction toward the position opposite to the connection between the second base plate 41 and the second side plate 12, the width of the slot 4121 gradually decreases.

[0077] Understandably, in this embodiment, the width of the latch 312 gradually increases from the position near the slot 4121 to the position away from the slot 4121. The latch 312 is formed as an inclined surface relative to the slot 4121. The inclined surface can play a guiding role, guiding the latch 312 to be gradually inserted into the slot 4121.

[0078] Meanwhile, in the folded state of the packaging box 100, the width of the card slot 4121 in this embodiment gradually decreases from bottom to top along the height direction of the packaging box 100. Since the latch 312 gradually increases in height from bottom to top, as the latch 312 extends into the card slot 4121, the position near the bottom of the packaging box 100 provides slightly more space for movement within the card slot 4121, facilitating the adjustment of the relative angle of the latch 312 relative to the card slot 4121. The position near the top of the packaging box 100 provides slightly less space for movement within the card slot 4121, and the shoulder 3121 of the latch 312 is also located near the top of the packaging box 100, which better limits the engagement depth of the latch 312.

[0079] like Figure 1 and Figure 2As shown, in this embodiment, the length of the first plate 311 along the width direction is half the length of the second side plate 12 along the length direction, so that the two tabs 312 are fitted together when the packaging box 100 is in a folded state.

[0080] Understandably, in order to ensure that the two latches 312 can be bent relative to the first plate 311 without adjustment and thus fit together, the length of the first plate 311 in this embodiment is half the length of the second side plate 12. This ensures that when the two first plates 311 are joined to form the bottom surface, the entire bottom surface is laid flat and the joining edges of the two first plates 311 abut against each other, so that the two latches 312 are bent at the same joining edge position and thus fit together firmly.

[0081] like Figure 1 As shown, each of the second base plates 41 in this embodiment is provided with a notch 414. The notch 414 extends along the width direction, and the notches 414 of the two second base plates 41 are arranged to face the same side along the length direction.

[0082] Understandably, in practical applications, to omit the process of connecting the side panel assembly 1 and the first bottom panel assembly 3 and the second bottom panel 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 and shipped from the factory. The pre-formed state is between the unfolded state and the folded state.

[0083] 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 first base plates 31 and two second base plates 41 are also connected. In actual use, the separated first side plates 11 and second side plates 12 can be glued together using glue or double-sided tape, and the first base plates 31 and second base plates 41 can be glued together on the bottom surface. To facilitate the transportation of the pre-formed packaging box 100, a notch 414 is provided on the second base plate 41. When pressure is applied to the frame formed by the assembled packaging box pieces, the notch 414 provides clearance space, allowing the frame of the packaging box pieces to become a flat stacked state, which is convenient for transport and storage. Furthermore, when packing the package, it is only necessary to open the pre-formed packaging box pieces and bend the free end of the second base plate 41 to complete the folding of the packaging box 100, without the need for manual gluing, thus improving the efficiency of packing.

[0084] 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 second base plates 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 second base plates 41 need to be located on the same side along the length direction to ensure that they are located on the diagonal of the rectangular bottom surface after the frame is formed.

[0085] like Figure 1 As shown, the notch 414 in this embodiment includes a triangular notch 4141 and a strip-shaped notch 4142.

[0086] A triangular notch 4141 is provided at one end of the second plate 411 facing the second side plate 12; a strip notch 4142 is connected to the triangular notch 4141, and the strip notch 4142 is located in the area where the second plate 411 and the snap-fit ​​part 412 are located.

[0087] 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 second plate 411 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 second bottom plate 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 second plate 411 and the snap-fit ​​part 412, which is more conducive to the bending of the second plate 411 and the snap-fit ​​part 412, and the shape is more regular after bending.

[0088] like Figure 1 As shown, in this embodiment, one of the two ends of the first plate 311 on the side away from the first side plate 11 is provided with a chamfer 3111, and the other end has an adhesive layer 3112, which is used to be pasted to the bottom surface of the packaging box 100; the two adhesive layers 3112 are located on the same side of the two first plates 311 along the length direction.

[0089] Understandably, to accommodate the pre-formed state of the packaging box pieces, one end of the first plate 311 has a chamfer 3111, and the other end has an adhesive layer 3112. The adhesive layer 3112 adheres one end of the first plate 311 to the second 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 line where the end with the chamfer 3111 is located. The chamfer 3111 provides clearance for the deformation of the rectangular bottom surface, and the adhesive layer 3112 ensures the connection between the side panel assembly 1 and the bottom surface when the frame is pressed into a flat stacked state.

[0090] It should be noted that, in order to ensure that the two snap-fit ​​parts 412 can separate when the frame is deformed, the adhesive layer 3112 can only be adhered to one of the second plates 411, and not both of the second plates 411.

[0091] Furthermore, since the adhesive layer 3112 is located on the same side of the two first plates 311, and the chamfer 3111 is also located on the same side of the two first plates 311, the two chamfers 3111 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.

[0092] like Figure 1 , Figure 2 and Figure 3 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.

[0093] 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.

[0094] 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.

[0095] like Figure 1 As shown, the packaging box cut piece in this embodiment also includes: a connecting piece 5.

[0096] The connecting piece 5 is located at one end of the side panel assembly 1 and is connected to the end of the first side panel 11 that is away from the second side panel 12.

[0097] 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.

[0098] 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.

[0099] Secondly, such as Figure 2 and Figure 3 As shown, this embodiment provides a packaging box 100, which is formed by folding the packaging box pieces as described above.

[0100] 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.

[0101] Understandably, if the packaging box pieces are made of corrugated paper, the packaging box 100 can be a corrugated cardboard box.

[0102] 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.
