Description

Technical Field

[0001] The utility model relates to the technical field of paper packaging boxes, in particular to a green and environmentally friendly packaging box. Background Art

[0002] Cardboard boxes can be used to package items or as express boxes, and are used in huge quantities every year.

[0003] When used as an express packaging box, the upper end of the box generally has four top panels, which are overlapped to seal the upper end of the box, and then sealed with tape to form a complete package to avoid opening during transportation. However, a large amount of tape is used, and after reaching the customer's hands, the sealing tape is generally torn off and discarded. The adhesion destroys the structure of the cardboard itself, and the tape itself is difficult to recycle, causing pollution. Therefore, existing packaging boxes can give priority to how to reduce the use of tape when sealing the packaging.

[0004] The problem that existing packaging boxes use a lot of tape when sealing needs to be solved. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a green and environmentally friendly packaging box in response to the above-mentioned technical deficiencies, which solves the problem that a large amount of adhesive tape is used in the sealing of existing packaging boxes.

[0006] The technical solution adopted by the utility model is to provide a green and environmentally friendly packaging box, comprising a box body provided with an opening, wherein the side periphery of the box body comprises four side panels connected in sequence along a ring; and further comprising:

[0007] The upper support plates have four upper support plates, each of which has an upper support plate obliquely arranged at the upper end of each side plate, and the four upper support plates are connected in sequence along a ring, and the lower end of the upper support plate is connected to the side plate, and the upper end of the upper support plate is located above the interior of the box body, and both sides of the upper support plate in the horizontal direction have convex edges, and the convex edges are vertically arranged, and two adjacent upper support plates are abutted and connected by the convex edges, and the two abutted convex edges constitute a vertically arranged support structure, and each support structure has a slot;

[0008] The box cover is used to cover the upper end of the upper support plate, and has a top plate and four lower edge plates. The four lower edge plates are arranged in a ring around the periphery of the top plate, and the lower edge plates are arranged at an angle. There is a positioning groove between every two adjacent lower edge plates. When the box cover covers the upper end of the upper support plate, the four lower edge plates correspond to the four upper support plates one by one, the lower edge plates abut against the upper support plate, the supporting structure passes through the positioning groove, and the lower edge plates are clamped in the clamping groove.

[0009] Further optimizing the technical solution, the support structure has a through hole; and further comprising:

[0010] There are several bayonet pins, which are inserted into the through holes to enhance the strength of the supporting structure.

[0011] To further optimize the technical solution, the end of the bayonet is a locking portion, the locking portion is located outside the through hole, and the side surface of the locking portion abuts against the upper side of the lower edge plate.

[0012] To further optimize the technical solution, the locking portion is a conical structure, a truncated cone structure, or a hemispherical structure, and the maximum diameter of the locking portion is greater than the diameter of the through hole.

[0013] To further optimize the technical solution, the upper portion of the side panel is provided with a plug-in slot; the lower side of the lower edge panel is provided with a card plate, and the card plate is plugged into the plug-in slot.

[0033] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0034] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0035] like Figure 1-10 As shown, a green and environmentally friendly packaging box includes a box body 1 with an opening, and the side of the box body 1 includes four side panels 101 connected in sequence along a ring; it also includes: an upper support plate 2, which has four, and an upper support plate 2 is obliquely provided on the upper end of each side panel 101. The four upper support plates 2 are connected in sequence along a ring, and the lower end of the upper support plate 2 is connected to the side panel 101. The upper end of the upper support plate 2 is located above the inside of the box body 1. Both sides of the upper support plate 2 in the horizontal direction have convex edges 201. The convex edges 201 are vertically arranged. Two adjacent upper support plates 2 are abutted and connected by the convex edges 201. The two abutted convex edges 201 constitute a The supporting structure 3 is arranged vertically, and each supporting structure 3 has a card slot 301; the box cover 4 is used to cover the upper end of the upper support plate 2, and has a top plate 401 and four lower edge plates 402. The four lower edge plates 402 are arranged in a ring around the outer periphery of the top plate 401, and the lower edge plates 402 are arranged at an angle. There is a positioning groove 404 between every two adjacent lower edge plates 402. When the box cover 4 covers the upper end of the upper support plate 2, the four lower edge plates 402 correspond to the four upper support plates 2 one by one, and the lower edge plates 402 abut against the upper support plate 2. The supporting structure 3 passes through the positioning groove 404, and the lower edge plates 402 are carded in the card slot 301.

[0036] During use, this application mainly solves the problem of waste and pollution of tape when sealing the box 1. The structure of the box 1 itself and the connection method of the bottom can be any method available in the existing technology. The main structure of the existing box 1 is partially adopted, and it can be manufactured with the help of existing molds or data parameters, reducing the cost of production line transformation and the trial and error cost of innovative structures.

[0037] The four upper support plates 2 form a prism structure at the upper end of the box body 1. The upper support plates 2 and the support structure 3 can be directly kneaded by the existing main structure of the packaging box. For example, the four sides of the existing packaging box body are vertically arranged, including four edge structures. The upper part of the edge structure is kneaded, and after kneading, it can be connected and positioned by gluing or anchoring with staples. The kneaded edges are the support structure 3. The support structure 3 is distributed at four right-angled positions. The support structure 3 is cut into grooves to form a card slot 301. The card slot 301 can be arranged horizontally or parallel to the upper support plate 2, which is convenient for the upper and lower and horizontal limiting of the lower edge plate 402.

[0038] When manufacturing the box body 1, reference can be made to existing technologies. Existing cardboard folding and connecting methods can be used to form the box body 1. Bend lines can be set on the side panels 101, which are bent to form the inclined upper support panels 2. Holes can also be pre-drilled at locations corresponding to the convex edges 201 on the upper support panels 2. After the boxes are assembled to form the box body 1, the locations of the holes will become the slots 301 of the support structure 3. Bend lines can also be set at the convex edges 201.

[0039] The box cover 4 can be formed by bending the support plate, and the side of the lower edge plate 402 can be dug with holes, and after docking, a positioning groove 404 is formed. The box cover 4 and the upper support plate 2 form a prism structure.

[0040] When the box body 1 is sealed using the box cover 4, the box cover 4 is buckled onto the upper support plate 2 from top to bottom, the support structure 3 passes through the positioning groove 404, and the lower edge plate 402 is partially engaged in the slot 301. When buckled, the box cover 4 can be contacted to deform and the support structure 3 can be displaced, so that the support structure 3 passes through the positioning groove 404 and the lower edge plate 402 is partially engaged in the slot 301.

[0041] Furthermore, the support structure 3 has a through hole 302 , and further includes: a plurality of bayonet pins 5 , which are inserted into the through hole 302 to enhance the strength of the support structure 3 .

[0042] During use, the through-hole 302 formed in the support structure 3 weakens the support structure 3, facilitating bending, deformation, or displacement, thereby allowing the support structure 3 to cooperate with the positioning groove 404, thereby facilitating smoother sealing. After sealing, the latch 5 is inserted into the through-hole 302, reinforcing the support structure 3 and improving the sealing stability.

[0043] The bayonet 5 can be made of paper material to form a cylindrical shape, etc. The bayonet 5 can be supported in the through hole 302. The through hole 302 and the bayonet 5 are not limited to be circular or the same shape.

[0044] Furthermore, the end of the latch 5 is a locking portion 501 . The locking portion 501 is located outside the through hole 302 , and the side surface of the locking portion 501 abuts against the upper side of the lower edge plate 402 .

[0045] When in use, both ends of the latch 5 may have a locking portion 501, which is located outside the through hole 302. The locking portion 501 abuts against the upper side of the lower edge plate 402, which can improve the fit between the lower edge plate 402 and the upper support plate 2 and improve the stability of the box cover 4.

[0046] Furthermore, the locking portion 501 is a conical structure, a truncated cone structure, or a hemispherical structure, and the maximum diameter of the locking portion 501 is greater than the diameter of the through hole 302 .

[0047] When in use, the locking portion 501 has a larger diameter, which can improve the stability of the locking pin 5 when inserted into the through hole 302 and prevent it from falling off the through hole 302.

[0048] Furthermore, the upper portion of the side panel 101 has a slot 1011, and the lower side panel 402 has a clip 403 on its underside, which is inserted into the slot 1011. Each side panel 101 has a slot 1011, and each lower side panel 402 has a clip 403 on its underside, with each clip 403 corresponding to each slot 1011. The end of the clip 403 has a clip 4031. When the clip 403 is inserted into the slot 1011, the clip 4031 snaps into place on the inner side of the case 1.

[0049] During use, the lid 4 can be stably secured in place by means of the positioning slots 404 at the four corners. The provision of the clamping plate 403 and the insertion slots 1011 can further enhance the sealing stability. The clamping plate 403 can be a square support plate structure that is inserted into the insertion slots 1011 with an interference fit, thus achieving a good effect.

[0050] The clamping plate 403 can be T-shaped, that is, a clamping head 4031 is provided on the end of the clamping plate 403. When the clamping plate 403 passes through the insertion slot 1011, the clamping head 4031 deforms and passes through the insertion slot 1011, and then abuts against the inner wall of the side plate 101. The clamping plate 403 and the clamping head 4031 can adopt existing clamping shapes.

[0051] The card plate 403 is located at the lower side of the lower edge plate 402, and the plug-in slot 1011 can be close to the lower end position of the lower pressure plate. When the card plate 403 is plugged into the plug-in slot 1011, the card plate 403 has a strong downward flipping force and can be more tightly abutted against the inner wall of the plug-in slot 1011, making the plug-in structure more compact.
