Description

Technical Field

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

[0002] Crafts are items that are transformed from raw materials into aesthetic value, decorative function, or cultural connotation through manual or machine processing. Crafts are often irregular in shape and are usually made of brittle materials such as ceramics, glass, and resin, requiring careful protection during transportation.

[0003] Existing packaging boxes are mostly designed for single use. If a customer needs to purchase multiple handicrafts (such as a pair of vases or a set of ornaments), they usually need to be packaged in two separate boxes. When a large number of customers place orders, merchants need to pre-package a large number of handicrafts, which may lead to errors in delivery and handling (vases not being paired or ornaments not being a set), causing losses to both customers and merchants. Therefore, there is a lack of a design that can securely connect two packaging boxes into a single unit and is easy to carry with one hand. Summary of the Invention

[0004] The purpose of this invention is to provide a packaging box that addresses the problem mentioned above: when carrying multiple handicrafts, it is usually necessary to carry two separate boxes, and there is a lack of a design that can stably connect the two packaging boxes into a whole and facilitate one-handed carrying.

[0005] The technical solution adopted in this invention to solve the technical problem is as follows: a packaging box, comprising: The box body has an opening on one side, and reinforcing plates are fixedly installed on the inner sides of both the left and right sides of the box body. Elastic strips are fixedly installed at the upper and lower ends of the reinforcing plates near the inner wall of the box body. A baffle plate has one end fixed to one side of the opening and the other end can be inserted into the box and engaged with the elastic strip. A plug-in assembly is provided on the side wall of the baffle plate. A first tear line is provided on the side wall of the box body opposite to the baffle plate. When the first tear line is torn, a plug-in hole is formed. The plug-in hole is used to connect with the plug-in assembly. A fixing component is disposed inside the box, which is used to fix and cushion the handicrafts placed inside the box.

[0006] This invention also includes the following technical features: In one embodiment of the present invention, a connecting component is provided between the upper and lower ends of the connection between the two boxes, the connecting component being used to seal and reinforce the connection between the upper and lower ends of the two adjacent boxes.

[0007] In one embodiment of the present invention, one end of the elastic strip is bonded to the side wall of the reinforcing plate, and the other end is bonded to the inner wall of the top and bottom ends of the box body. An insertion channel is formed between the reinforcing plate, the side wall of the box body, and the elastic strip. An inner baffle is provided on the side of the reinforcing plate away from the elastic strip.

[0008] In one embodiment of the present invention, inclined toothed grooves are provided on both the upper and lower sides of the free end of the baffle plate, and inverted teeth are formed at the free end of the baffle plate. When the upper and lower ends of the baffle plate are inserted into the insertion channel by pressing the elastic strip, the inverted teeth and the elastic strip are engaged.

[0009] In one embodiment of the present invention, the plug-in assembly includes a second tear line formed on a shield plate, and a third tear line is provided at both the upper and lower ends of the second tear line. A plug-in plate is provided within the second tear line and the third tear line, and a limit plate is provided on both the upper and lower sides of the free end of the plug-in plate.

[0010] In one embodiment of the present invention, when the second tear line tears, the plug plate rotates out from the shield plate, and a through hole is formed at the second tear line; when the third tear line tears, a clearance hole is formed at the tear.

[0011] In one embodiment of the present invention, when the shielding plate is inserted into the insertion channel, the through hole and the clearance hole are located inside the insertion hole. The free end of the insertion plate is bent to one side at a 90-degree angle, and the limiting plate is bent to one side. The bent part of the insertion plate passes through the insertion hole, while the limiting plate is located inside the clearance hole. After the limiting plate is reset, it engages with the inner wall of the insertion hole.

[0012] In one embodiment of the present invention, the fixing component includes a snap-fit ​​assembly and a buffer assembly. The snap-fit ​​assembly is located on the top and bottom sides of the inner end of the box body and is used to secure the top and bottom ends of the craft. The buffer assembly is located in the middle of the snap-fit ​​assembly and is used to fit onto the outer end of the craft and to cushion and reduce shock for the craft.

[0013] In one embodiment of the present invention, the snap-fit ​​assembly includes a top base, the top base includes two symmetrically arranged shock-absorbing blocks, the upper end of the top base is provided with an insertion groove, the inner end of the insertion groove is provided with a snap-fit ​​groove, and a first socket plate is snapped into place through the snap-fit ​​groove. The middle part of the first socket plate is provided with a circular hole, and a plurality of snap-fit ​​blocks are evenly arranged at the inner end of the circular hole. A fourth tear line is provided between two adjacent snap-fit ​​blocks.

[0014] In one embodiment of the present invention, the snap-fit ​​assembly includes a cardboard with two layers. Buffer blocks are fixedly installed between the two layers of cardboard and on the side wall of the inner cardboard. A mating groove is provided on the side wall of the buffer block on the inner cardboard. The cardboard is folded into a rectangle and fitted with a second socket plate through the mating groove. The inner end structure of the second socket plate is the same as the inner end structure of the first socket plate.

[0015] In one embodiment of the present invention, the connecting component includes a connecting strip, one end of which is fixedly mounted with a connecting plate. When the two boxes are spliced ​​together, the front and rear ends of the connecting plate are respectively inserted between the top and bottom ends of the two boxes and the inner baffle, while the connecting strip is located between the upper and lower ends of the two boxes.

[0016] Compared with existing technologies, the beneficial effects of this invention are reflected in: By setting plug-in components on the shield and plug-in holes on the box body, two boxes can be spliced ​​into one large box, which makes it convenient to package a pair or a set of handicrafts at one time, avoiding the problems of chaotic or wrong shipments. At the same time, the connecting components fill the gaps at the splicing points, which not only improves the overall structural strength, but also ensures the aesthetics and sealing of the spliced ​​items. The elastic strip at the box opening engages with the counter-teeth on the baffle, and the insertion components on the baffle engage with the insertion holes on the side wall of the box. When the baffle is inserted, the counter-teeth compress the elastic strip to achieve a one-way locking, preventing accidental pop-out. To open, simply pull it; operation is simple. By incorporating a fixing component consisting of a snap-fit ​​assembly and a cushioning assembly, the snap-fit ​​block can be torn and fitted to the protruding parts of the craft, enabling it to fix and support crafts of different shapes. This achieves a tight lock on irregularly shaped crafts, and together with the elastic strip and shock-absorbing block made of pearl sponge material, it provides all-round cushioning protection.

[0019] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0020] The illustrations provided in this embodiment are only intended to illustrate the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the shape, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0021] It should be noted that the cardboard used in this packaging box is all high-density cardboard, and decorative paper can be pressed onto the outer end of the high-density cardboard as needed.

[0022] Please see Figures 1 to 14 This invention provides a technical solution: a packaging box, including a box body 10. One side of the box body 10 has an opening for taking out and placing handicrafts. Reinforcing plates 20 are fixedly installed on the inner sides of both the left and right sides of the box body 10. The reinforcing plates 20 are used to strengthen the box body 10, allowing it to better protect the handicrafts inside. Elastic strips 21 are fixedly installed at both the upper and lower ends of the reinforcing plate 20 near the inner wall of the box body 10. The elastic strips 21 are made of pearl sponge, which has good elasticity and is a common cushioning filler for packaging boxes. One end of the elastic strip 21 is adhered to... The side wall of the reinforcing plate 20 is glued to the inner wall of the top and bottom of the box body 10 at the other end, fixing the reinforcing plate 20 and the elastic strip 21. An insertion channel is formed between the reinforcing plate 20, the side wall of the box body 10 and the elastic strip 21, which is used to insert the shielding plate 12 and fix the shielding plate 12, thereby blocking the opening of the box body 10. An inner baffle 22 is provided on the side of the reinforcing plate 20 away from the elastic strip 21. The inner baffle 22 and the reinforcing plate 20 are integrated. The inner baffle 22 can rotate at one end of the reinforcing plate 20. The inner baffle 22 is used to block the fixed parts inside the box body 10. One end of the baffle 12 is fixed to one side of the opening, and the other end can be inserted into the box 10 and engaged with the elastic strip 21 to block the opening of the box 10. A plug-in component is provided on the side wall of the baffle 12. A first tear line 101 is provided on the side wall of the box 10 opposite to the baffle 12. When the first tear line 101 is torn, a plug-in hole 102 is formed. The plug-in hole 102 is used to connect with the plug-in component and fix the plug-in component. The fixing component is set inside the box 10 and is used to fix and cushion the handicrafts placed inside the box 10.

[0023] Specifically, a fixing component is attached to the outer end of the craft, and then the fixing component and the craft are inserted into the box 10 through the opening until the inner end of the fixing component contacts the inner wall of the box 10. Then, the inner baffle 22 is rotated to fit the inner baffle 22 against the outer end of the fixing component.

[0024] In one embodiment, such as Figure 1 and Figure 8 As shown, inclined toothed grooves 124 are provided on both the upper and lower sides of the free end of the baffle plate 12, forming reverse teeth at the free end of the baffle plate 12. When the upper and lower ends of the baffle plate 12 are inserted into the insertion channel by pressing the elastic strip 21, the reverse teeth and the elastic strip 21 are engaged. The free end of the baffle plate 12 is provided with creases, which allow the reverse teeth to rotate 90 degrees at the free end of the baffle plate 12.

[0025] Specifically, when the box 10 is used alone, the crafts are first wrapped and secured by the fixing component. Then, the fixing component is placed into the box 10 along with the crafts through the opening. Next, the free end of the cover plate 12 is folded inward at a 90-degree angle along the crease. Then, the cover plate 12 is rotated to cover the opening. At the same time, the upper and lower ends of the bent part of the cover plate 12 are inserted into the insertion channel by squeezing the elastic strip 21 until the cover plate 12 is completely fitted to the outside of the opening. When the back teeth move outward, they will lock with the elastic strip 21, thereby fixing the cover plate 12. By pulling the cover plate 12 outward with force, the cover plate 12 can be pulled out from the insertion channel, making it easy to put in and take out the crafts.

[0026] In one embodiment, such as Figures 2-7 As shown, the plug-in assembly includes a second tear line 121 formed on the baffle plate 12. Both the upper and lower ends of the second tear line 121 are provided with third tear lines 122. A plug-in plate 123 is provided inside the second tear line 121 and the third tear line 122. When the second tear line 121 and the third tear line 122 are torn, one end of the plug-in plate 123 is connected to the baffle plate 12 and can rotate on the baffle plate 12. Limiting plates 1231 are provided on both the upper and lower sides of the free end of the plug-in plate 123. A crease is provided at the connection between the limiting plate 1231 and the plug-in plate 123 so that the limiting plate 1231 can rotate on the plug-in plate 123.

[0027] When the second tear line 121 tears, the plug plate 123 rotates out from the baffle plate 12, and a through hole 1211 is formed at the second tear line 121. After the third tear line 122 tears, a clearance hole 1221 is formed at the tear. The height of the through hole 1211 is the same as the height of the plug hole 102. When the baffle plate 12 is inserted into the plug channel, the through hole 1211 and the clearance hole 1221 are located inside the plug hole 102. The free end of the plug plate 123 is bent to one side at a 90-degree angle, and the limiting plate 1231 is bent to one side. The bent part of the plug plate 123 passes through the plug hole 102, and the limiting plate 1231 is located inside the clearance hole 1221. After the limiting plate 1231 is reset, it is engaged with the inner wall of the plug hole 102, thus fixing the plug plate 123.

[0028] Specifically, when splicing the two boxes 10, the first tear line 101 is first torn to form an insertion hole 102 on the side wall of the box 10. Then, the second tear line 121 and the third tear line 122 are torn to form a through hole 1211 and a clearance hole 1221 on the side wall of the baffle plate 12. One end of the insertion plate 123 is rotated outward, and the free end of the insertion plate 123 is bent at ninety degrees along the crease. Then, the baffle plates 12 on the two boxes 10 are inserted into the insertion channel of the other box, with the upper and lower ends of the baffle plate 12 in close contact with the elastic strip 21, until the two boxes 10 are connected together. At the same time, the through hole 102 is opened. 211 and the clearance hole 1221 are located inside the insertion hole 102. Finally, the limiting plate 1231 is bent to one side, and the bent part of the insertion plate 123 passes through the insertion hole 102. The limiting plate 1231 is located inside the clearance hole 1221. The limiting plate 1231 is reset under its own elasticity. After the limiting plate 1231 is reset, it is engaged with the inner wall of the insertion hole 102, fixing the insertion plate 123. Thus, the shielding plate 12 of one box 10 is fixed in the insertion channel of another box 10. The two boxes 10 are spliced ​​together, which can package two handicrafts at one time, and the transportation is more convenient, avoiding the problems of chaotic delivery and wrong delivery.

[0029] In one embodiment, such as Figures 2-3 and Figure 10 As shown, a connecting component is provided between the upper and lower ends of the connection between the two boxes 10. The connecting component is used to seal and reinforce the upper and lower ends of the two adjacent boxes 10. The connecting component includes a connecting strip 30. A connecting plate 31 is fixedly installed at one end of the connecting strip 30. The width of the connecting plate 31 is greater than the width of the connecting strip 30. The length of the connecting strip 30 is the same as the width of the box 10. The length of the connecting plate 31 is less than the width between the two reinforcing plates 20. The cross section of the combination of the connecting strip 30 and the connecting plate 31 is convex. When the two boxes 10 are spliced, the front and rear ends of the connecting plate 31 are respectively inserted between the top and bottom ends of the two boxes 10 and the inner baffle 22. At the same time, the connecting strip 30 is located between the upper and lower ends of the two boxes 10.

[0030] Specifically, when the two boxes 10 are spliced ​​together, when the baffle 12 of the box 10 is inserted into the insertion channel, the connection between the baffle 12 and the box 10 will bend inward, causing a gap to appear between the upper and lower ends of the two boxes 10 after splicing, which seriously affects the aesthetics, as well as the sealing and connection strength of the connection. A connecting component is inserted between the two boxes 10, so that the two ends of the connecting plate 31 are respectively inserted into the connecting groove formed between the inner baffle 22, the reinforcing plate 20 and the inner wall of the box 10. At the same time, the connecting strip 30 is located between the top and bottom ends of the two boxes 10 to seal the connection, improve the connection strength and improve the aesthetics.

[0031] In one embodiment, such as Figure 1 and Figure 2As shown, lifting plates 11 are provided on both the left and right sides of the upper end of the box body 10. A crease is provided at the connection between the lifting plate 11 and the box body 10. The lifting plate 11 can rotate freely at the upper end of the box body 10. A bendable bending plate 111 is provided at the free end of the lifting plate 11. A lifting hole 112 is provided on the bending plate 111.

[0032] Specifically, when using box 10 alone, by lifting the two lifting plates 11 upwards and rotating the bending plate 111 so that the two bending plates 111 are parallel, the user can lift box 10 by inserting four fingers of the palm into the two parallel lifting holes 112. When two boxes 10 need to be used together, by rotating the lifting plates 11 of the two boxes 10 close to each other until they are perpendicular to the top surface of the box 10, the user can lift both boxes 10 together by inserting four fingers of the palm into the two parallel lifting holes 112, making them easier to carry and use.

[0033] In one embodiment, such as Figure 9 , Figures 12-14 As shown, the fixing components include a snap-fit ​​assembly and a buffer assembly. The snap-fit ​​assembly is located on the top and bottom sides of the inner end of the box 10 and is used to secure the top and bottom ends of the craft. The buffer assembly is located in the middle of the snap-fit ​​assembly and is used to fit onto the outer end of the craft to cushion and reduce shock.

[0034] The snap-fit ​​assembly includes a top base 40, which includes two symmetrically arranged shock-absorbing blocks made of pearl sponge, which serve to cushion and reduce shock for the handicrafts. The top base 40 has an insertion groove 41 at its upper end, and a snap-fit ​​groove 411 at its inner end. When the two shock-absorbing blocks are spliced ​​together, the insertion groove 41 is circular, and the snap-fit ​​groove 411 is annular. The first socket plate 50 is snapped into place through the snap-fit ​​groove 411. By fitting the two shock-absorbing blocks onto the outer end of the first socket plate 50, the snap-fit ​​groove 411 and the outer wall of the first socket plate 50 are made to fit together. At the same time, the connection points of the two shock-absorbing blocks are fitted together, fixing the first socket plate 50 inside the two shock-absorbing blocks. The middle part of the first socket plate 50 has a circular hole 51, and multiple snap-fit ​​blocks 52 are evenly arranged at the inner end of the circular hole 51. A fourth tear line 53 is provided between two adjacent snap-fit ​​blocks 52.

[0035] Specifically, when it is necessary to fix the handicraft, first insert the lower end of the handicraft into the round hole 51 in the middle of the fixed first socket plate 50. The lower end of the handicraft contacts the snap-fit ​​block 52, allowing its lower end to pass through the round hole 51 and sit in the insertion groove 41. The protruding part of the handicraft pushes the snap-fit ​​block 52 to one side, and at the same time tears the fourth tear line 53, allowing the snap-fit ​​block 52 to adhere to the outer wall of the handicraft. Then, a set of snap-fit ​​components is fitted on the top of the handicraft to fix the handicraft in place, which is convenient for fixing handicrafts of different shapes.

[0036] The snap-fit ​​assembly includes a cardboard 60, which has two layers. Buffer blocks 61 are fixedly installed between the two layers of cardboard 60 and on the side wall of the inner cardboard 60. The buffer blocks 61 are made of trapezoidal hollow paper sheets, which can absorb impact force through deformation when subjected to impact. The side wall of the buffer block 61 on the inner cardboard 60 is provided with a mating groove 62. The cardboard 60 is folded into a rectangle and a second socket plate 70 is fitted through the mating groove 62 to fix the second socket plate 70 to the inside of the cardboard 60. The inner end structure of the second socket plate 70 is the same as the inner end structure of the first socket plate 50.

[0037] More specifically, the cardboard 60 is folded into a rectangle and the second connecting plate 70 is fitted onto it. The second connecting plate 70 is then fitted onto the outer end of the craft, thereby fitting the cushioning component onto the outer end of the craft. Next, snap-fit ​​components are inserted into the top and bottom ends of the craft. Then, the craft, the cushioning component, and the snap-fit ​​components are pushed into the box 10 from the opening, so that the three side walls of the cardboard 60 contact the three inner walls of the box 10. At the same time, the top and bottom ends of the top base 40 contact the inner walls of the top and bottom ends of the box 10, and the three side walls of the top base 40 on the same horizontal plane contact the three inner walls of the box 10. Then, the inner baffle 22 and the fixed baffle 12 are rotated to fix the craft inside the box 10. This can fix crafts of different shapes and has a cushioning and shock-absorbing effect on the craft.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
