Description

Technical Field

[0001] This utility model relates to the technical field of packaging boxes, specifically an e-commerce packaging box. Background Technology

[0002] E-commerce has broken the time and space limitations of traditional buying and selling, making it possible to complete the entire process of shopping, ordering, payment, and delivery online. It has not only changed consumers' shopping habits but also reshaped how businesses operate, and has become an indispensable part of the modern economy.

[0003] E-commerce goods typically require paper packaging boxes for transportation. To support and protect the goods from bumps and damage during transport, traditional packaging boxes usually use a large amount of EPS foam, EPE pearl cotton, polyurethane foam, or other lightweight, elastic materials such as air columns and bubble wrap to wrap the packaged items or fill the gaps between the goods and the packaging box. For e-commerce companies, these bulky packaging materials occupy a lot of storage space, increasing warehousing costs. During transportation, they also increase the "volume weight" of packages, reducing the amount of goods that can be loaded per vehicle / machine, thus indirectly increasing logistics costs. For users, after receiving the goods, they also need to deal with paper packaging materials and plastic fillers. Although the fillers themselves are not heavy, they take up a lot of space and quickly fill up trash cans and waste transfer stations, reducing the efficiency of waste collection and transportation. For waste treatment or recycling organizations, the cost of collecting, transporting, and cleaning fillers far exceeds the value of their recycled materials, which is detrimental to the environment.

[0004] Chinese Patent No. ZL202222048406.X discloses a cushioning and shock-absorbing structure for packaging boxes and a packaging box, including a substrate; a cushioning element, wherein at least one pair of opposing cushioning elements are constructed on the substrate and all cushioning elements are located on the same side of the substrate, and the cushioning element is provided with a bending line; when the substrate and / or the cushioning element is squeezed by an external force, the cushioning element can be bent along the bending line under the squeezing action of the external force; the packaging box includes a flip cover and the cushioning and shock-absorbing structure for packaging boxes as described above, the flip cover is connected to the substrate through the cushioning element; the flip cover can be closed on the substrate by folding and connected to the two opposing cushioning elements, solving the problem of poor shock absorption effect of traditional packaging box cushioning structures. However, this packaging box can only absorb the pressure from above and below through its cushioning and shock-absorbing structure. If the packaged item is smaller than the cushioning and shock-absorbing structure, there will be shaking and collision problems during transportation and use, and the packaged item cannot be further fixed, so the cushioning and shock absorption effect is limited. Summary of the Invention

[0005] The technical problem to be solved by this utility model is how to improve the cushioning and shock absorption effect of the packaging box and prevent the goods from shaking. The purpose of this utility model is to provide an e-commerce packaging box that can adaptively and lockably package the packaged items by achieving predictable elastic deformation through controllable rigidity weakening inside the cardboard box.

[0006] The technical solution adopted by this utility model is as follows: an e-commerce packaging box, including a box body and a box lid. The box lid includes a top plate, side fastening plates, and a front fastening plate. The side fastening plates are located on the left and right sides of the top plate, and the front fastening plate is located on the upper side of the top plate. The box body includes a bottom plate, side panels, a front panel, and a back plate. The side panels are located on the left and right sides of the bottom plate, and the front panel and back plate are located on the upper and lower sides of the bottom plate, respectively. The box body also includes a front limiting plate, a lower reinforcing plate, and an upper reinforcing plate. The top of the front limiting plate is connected to the bottom of the front panel, the lower reinforcing plate is connected to the bottom of the front limiting plate, and the upper reinforcing plate is connected to the bottom of the lower reinforcing plate. Multiple radial cutting grooves are evenly distributed on the upper and lower reinforcing plates.

[0007] The following benefits can be achieved by using the e-commerce packaging box provided by this utility model: (1) The product is clamped and fixed by overlapping the upper and lower reinforcing plates. Each radial cutting groove on the upper and lower reinforcing plates can serve as a local deformation zone, allowing the surrounding cardboard material to shift and deflect under force. When adapting to the shape of the product, the gap can be automatically expanded to transfer the force of the product to other adjacent radial cutting grooves. By causing the upper and lower reinforcing plates with radial cutting grooves to undergo controllable bending deformation to fit the product, the product is clamped and fixed while being suspended, providing a buffer and shock absorption effect to prevent collision or damage during transportation.

[0008] (2) After packaging, the radial cutting grooves on the upper and lower reinforcing plates can adapt to deformation after being subjected to the reaction force of the goods, while the unforced parts do not deform. Therefore, goods of different sizes that can be put into the packaging box can be effectively clamped and fixed, making it convenient to use.

[0009] (3) By using a single piece of paper packaging material that can be unfolded and folded, without the need for additional fluffy packaging or filling materials, storage costs, packaging costs, transportation costs and waste disposal costs are reduced, making recycling easier and more in line with environmental protection requirements.

[0010] Preferably, the radial cutting groove includes multiple release grooves of equal length, one end of each release groove in the radial cutting groove is connected to each other and arranged in a ring at equal intervals around the connection point, and each release groove has a circular anti-crack hole at its end.

[0011] The release groove can release the stress and strain generated inside the paper material of the upper or lower reinforcing plate when it is subjected to force, providing space and freedom for deformation, making it easier for the upper and lower reinforcing plates to fit the shape of the product, which is beneficial for better clamping the product and providing cushioning; the anti-crack hole can transform the sharp stress at the end of the release groove into a more controllable and fatigue-resistant smooth stress distribution area, preventing the release groove from continuing to tear along the gap when it expands and deforms, thus allowing the upper or lower reinforcing plate to adapt to greater contour changes.

[0012] Preferably, the number of release slots in each of the radial cutting slots is not less than three.

[0013] By ensuring that each radial cutting groove contains at least three release grooves, the deformation and expansion of the radial cutting grooves are diffused in all directions, rather than concentrated in one direction. This avoids the problem of material fracture caused by concentrated stress on two adjacent radial cutting grooves.

[0014] Preferably, the shortest distance between adjacent radial cutting grooves is less than the length of the release groove.

[0015] By shortening the shortest distance between adjacent radial cutting grooves, the density of radial cutting groove distribution is increased, and the force on each radial cutting groove can be preferentially transmitted to the surrounding radial cutting grooves, which is more conducive to the radial cutting grooves conforming to the shape of the product after deformation.

[0016] Preferably, the dimensions of the lower reinforcing plate are the same as those of the upper reinforcing plate.

[0017] By making the lower reinforcing plate the same size as the upper reinforcing plate, the product can be completely wrapped after the lower and upper reinforcing plates are folded together, preventing the product from falling out of the area held by the lower and upper reinforcing plates.

[0018] Preferably, both the left and right sides of the lower reinforcing plate are connected to lower support plates.

[0019] The lower support plates on both sides can restrict the position of the lower reinforcing plate. After folding, the lower support plates support the bottom plate of the box, preventing the lower reinforcing plate from shaking up and down, and ensuring that the upper and lower reinforcing plates fit tightly together.

[0020] Preferably, the upper reinforcing plate is provided with upper support plates on both the left and right sides.

[0021] The upper support plates on both sides can restrict the position of the upper reinforcing plate. After folding and the lid is placed on the box, the upper support plate supports the bottom of the top plate in the lid, preventing the upper reinforcing plate from shaking up and down, and ensuring that the upper and lower reinforcing plates fit tightly together.

[0022] Preferably, the length of the positive limiting plate is equal to the length of the front panel, the width of the positive limiting plate is half the height of the front panel, and the width of the positive limiting plate is equal to that of the lower support plate.

[0023] The lower reinforcing plate is limited by the positive limiting plate, so that the four sides of the lower reinforcing plate are on the same horizontal plane after folding, while preventing the lower reinforcing plate from shaking up and down.

[0024] Preferably, the left and right sides of the front panel, back panel, and front snap-fit ​​panel are all connected with adhesive flaps for use after the packaging box is folded and glued. After folding, the adhesive flaps on the left and right sides of the front panel and back panel are respectively glued to the front and rear ends of the left and right side panels of the bottom panel, and the adhesive flaps on the left and right sides of the front snap-fit ​​panel are glued to the left and right side snap-fit ​​panels of the top panel.

[0025] After the packaging box is folded and formed, the adhesive flaps are glued together to form the box body and lid.

[0026] Preferably, the upper side of the back panel is connected to the lower side of the top panel, so that the box body and the box lid are connected together.

[0027] By connecting the box body and the lid together, it is easier to form a single die-cutting pattern during production, which facilitates mass production.

[0028] Preferably, the side panel away from the bottom plate is connected to a side support plate.

[0029] The side support panels can support both sides of the box when folded inward, strengthening the box and fixing its shape. Attached Figure Description

Detailed Implementation

[0033] The following will be combined with the appendix Figure 1-7 The technical solution of this utility model is clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] Example 1 The following description, in conjunction with specific embodiments, provides further details. Figure 1-7As shown, this embodiment is an e-commerce packaging box, including a box body 1 and a box lid 2. The box lid 2 includes a top plate 21, side fastening plates 22, and a front fastening plate 23. The side fastening plates 22 are located on the left and right sides of the top plate 21, and the front fastening plate 23 is located on the upper side of the top plate 21. The box body 1 includes a bottom plate 11, side panels 13, a front panel 12, and a back plate 18. The side panels 13 are located on the left and right sides of the bottom plate, and the front panel 12 and the back plate 18 are located on the upper and lower sides of the bottom plate, respectively. The box body 1 also includes a front limiting plate 14, a lower reinforcing plate 15, and an upper reinforcing plate 16. The top of the front limiting plate 14 is connected to the bottom of the front panel 12, the lower reinforcing plate 15 is connected to the bottom of the front limiting plate 14, and the upper reinforcing plate 16 is connected to the bottom of the lower reinforcing plate 15. The upper reinforcing plate 16 and the lower reinforcing plate 15 have multiple radially spaced cutting grooves 17. The reinforcing plates 15 overlap to clamp and fix the goods. Each radial cut groove 17 on the upper reinforcing plate 16 and the lower reinforcing plate 15 can act as a local deformation zone, allowing the surrounding cardboard material to shift and deflect under force. When adapting to the shape of the goods, the gaps can automatically expand, transferring the force of the goods to other adjacent radial cut grooves 17. By causing the upper reinforcing plate 16 and the lower reinforcing plate 15 with radial cut grooves 17 to undergo controllable bending deformation to fit the goods, the upper reinforcing plate 16 and the lower reinforcing plate 15 provide cushioning and shock absorption while clamping and fixing the goods, preventing collisions or damage during transportation. By clamping and fixing the goods through the upper reinforcing plate 16 and the lower reinforcing plate 15 connected to the packaging box, there is no need to use fluffy packaging or filling materials, reducing warehousing costs, packaging costs, transportation costs and waste disposal costs, facilitating recycling and disposal, and meeting environmental protection requirements.

[0036] Reference Figure 5 or Figure 7 As shown, in this embodiment, the radial cutting groove 17 includes a plurality of release grooves 171 of equal length. One end of each release groove 171 in the radial cutting groove 17 is connected to each other and arranged in a ring at equal intervals around the connection point. Each end of the release groove 171 is provided with a circular anti-crack hole 172. The release groove 171 can release the stress and strain generated inside the paper material of the upper reinforcing plate 16 or the lower reinforcing plate 15 when it is under force, providing space and freedom for deformation, making it easier for the upper reinforcing plate 16 and the lower reinforcing plate 15 to fit close to the shape of the product, which is beneficial for better clamping the product and providing cushioning. The anti-crack hole 172 can transform the sharp stress at the end of the release groove 171 into a more controllable and fatigue-resistant smooth stress distribution area, preventing the release groove 171 from continuing to tear along the gap when it expands and deforms, thereby allowing the upper reinforcing plate 16 or the lower reinforcing plate 15 to adapt to greater contour changes.

[0037] Reference Figure 5 or Figure 7As shown, in this embodiment, the number of release slots 171 in each radial cutting groove 17 is not less than three. By ensuring that there are not less than three release slots 171 in each radial cutting groove 17, the direction of deformation and expansion of the radial cutting groove 17 is diffused in all directions, rather than concentrated in the same direction. This avoids the problem of paper material breaking due to concentrated force on two adjacent radial cutting grooves 17.

[0038] Reference Figure 5 or Figure 7 As shown, in this embodiment, the shortest distance between adjacent radial cutting grooves 17 is less than the length of the release groove 171. By shortening the shortest distance between adjacent radial cutting grooves 17, the density of radial cutting grooves 17 is increased, and the force on each radial cutting groove 17 can be preferentially transmitted to the surrounding radial cutting grooves 17, which is more conducive to making the radial cutting grooves 17 conform to the shape of the product after deformation.

[0039] Reference Figure 1 As shown, in this embodiment, the size of the lower reinforcing plate 15 is the same as that of the upper reinforcing plate 16. By making the size of the lower reinforcing plate 15 the same as that of the upper reinforcing plate 16, the lower reinforcing plate 15 and the upper reinforcing plate 16 can both wrap around the product after being folded together, preventing the product from falling out of the area held by the lower reinforcing plate 15 and the upper reinforcing plate 16.

[0040] Reference Figure 1 As shown, in this embodiment, the lower reinforcing plate 15 is connected to the left and right sides of the lower reinforcing plate 15. The lower supporting plates 151 on both sides can restrict the position of the lower reinforcing plate 15. After folding, the lower supporting plates 151 support the bottom plate 11 of the box to prevent the lower reinforcing plate 15 from shaking up and down, so that the upper reinforcing plate 16 and the lower reinforcing plate 15 fit tightly together.

[0041] Reference Figure 1 or Figure 4 As shown, in this embodiment, upper support plates 161 are provided on both the left and right sides of the upper reinforcing plate 16. The upper support plates 161 on both sides can restrict the position of the upper reinforcing plate 16. After folding and the lid 2 is placed on the box body 1, the upper support plates 161 support the bottom of the top plate 21 in the lid 2 to prevent the upper reinforcing plate 16 from shaking up and down, so that the upper reinforcing plate 16 and the lower reinforcing plate 15 fit tightly together.

[0042] Reference Figure 1 or Figure 4As shown, in this embodiment, the length of the positive limiting plate 14 is equal to the length of the front panel 12, the width of the positive limiting plate 14 is half the height of the front panel 12, and the width of the positive limiting plate 14 is equal to that of the lower support plate 151. The positive limiting plate 14 limits the lower reinforcing plate 15, so that the four sides of the lower reinforcing plate 15 are on the same horizontal plane after folding, while preventing the lower reinforcing plate 15 from shaking up and down.

[0043] Reference Figure 1 and Figure 2-4 As shown, in this embodiment, the left and right sides of the front panel 12, back panel 18, and front snap-fit ​​panel 23 are all connected with adhesive flaps 3, which serve as adhesive after the packaging box is folded and glued. After folding, the adhesive flaps 3 on the left and right sides of the front panel 12 and back panel 18 are respectively glued to the front and rear ends of the left and right side panels 13 on the bottom panel 11. After folding, the adhesive flaps 3 on the left and right sides of the front snap-fit ​​panel 23 are glued to the left and right side snap-fit ​​panels 22 on the top panel 21. After the packaging box is folded, the adhesive flaps 3 are glued and connected to form the box body 1 and the box lid 2 by gluing and fixing the side panels 13 and side snap-fit ​​panels 22 on both sides of the packaging box.

[0044] Reference Figure 1 or Figure 4 As shown, in this embodiment, the upper side of the back plate 18 is connected to the lower side of the top plate 21, so that the box body 1 and the box cover 2 are connected together. By connecting the box body 1 part and the box cover 2 part together, it is convenient to form an integral cutting board pattern during production, which is convenient for mass production.

[0045] Reference Figure 1-3 As shown, in this embodiment, the side panel 13 is connected to a side support plate 131 on the side away from the bottom plate 11. The side support plate 131 can support both sides of the box body 1 after being folded inward, thereby strengthening the box body 1 and fixing the shape of the box body 1.

[0046] Example 2 When using this utility model, first fold the adhesive flaps on the left and right sides of the back panel 18, apply glue, and stick them to the upper surface of the side panel 13. Then fold the adhesive flaps on the left and right sides of the front panel 12, apply glue, and stick them to the upper surface of the side panel 13, so that the back panel 18 and the front panel 12 are perpendicular to the bottom panel 11. Then fold the two side support plates 131 connected to the side panel 13 inward, so that the side support plates 131, the side panel 13, and the adhesive flaps fixed on the side panel 13 are glued together to form the box body 1. Then fold the adhesive flaps on the left and right sides of the front fastening plate 23, apply glue, and stick them to the upper surface of the side fastening plate 22. The front and side fastening plates 23 and 22 are glued together so that they are perpendicular to the top plate 21, forming the lid 2. Then, the front limiting plate 14 is folded towards the bottom plate 11 so that it is attached to the inside of the front panel 12. The lower support plate 151 is folded upwards until it is perpendicular to the top plate 12. Then, it is folded along the dividing line between the front limiting plate 14 and the lower reinforcing plate 15. The lower reinforcing plate 15 is flipped into the box body 1 until the edges of the lower support plates 151 on both sides of the lower reinforcing plate 15 are attached to the upper surface of the bottom plate 11. The upper reinforcing plate 16 is folded downwards along the dividing line between the lower reinforcing plates 15 and the upper reinforcing plate 16. Figure 2 As shown; When packaging goods, the goods to be packaged are placed on the upper surface of the lower reinforcing plate 15. Then, the upper reinforcing plate 16 is folded down so that the lower surfaces of the upper and lower reinforcing plates 16 are in contact with each other. Since multiple radial cutting grooves 17 are evenly distributed on both the upper and lower reinforcing plates 16 and 15, the radial cutting grooves 17 can deform and flip to a certain extent. After deformation, the upper and lower reinforcing plates 16 and 15 with radial cutting grooves 17 can fit tightly against the upper and lower surfaces of the goods, thereby clamping and fixing the goods. Finally, the box cover 2 is flipped down so that it is fastened onto the box body 1. The upper support plates 161 on the left and right sides of the upper reinforcing plate 16 abut against the lower surface of the top plate 21 of the box cover 2. Finally, the upper support plates 161 and the lower support plates 161 are supported by the box body 1 and the box cover 2, respectively. The support plate 151, upper support plate 161, and lower support plate 151 respectively support the upper reinforcing plate 16 and the lower reinforcing plate 15, so that the upper reinforcing plate 16 and the lower reinforcing plate 15 are firmly attached together. At the same time, the multiple radial cut grooves 17 on the upper reinforcing plate 16 and the lower reinforcing plate 15 undergo controllable bending deformation under the reaction force of the goods, so as to better conform to the shape of the goods. By suspending and clamping the goods between the upper reinforcing plate 16 and the lower reinforcing plate 15, the goods are fixed and cushioned to prevent them from moving during transportation. Since the packaging is a single piece of paper packaging material that can be unfolded and folded, there is no need to use additional fluffy packaging or filling materials, which reduces storage costs, packaging costs, transportation costs, and waste disposal costs. It is also easy to recycle and is more in line with environmental protection requirements.
