Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a high-strength fruit printing packaging box. Background Technology

[0002] Most existing fruit packaging boxes are flat cardboard boxes. When long-distance transportation is required, the boxes are stacked together. Due to the poor strength of the cardboard boxes themselves, they are prone to collapse, which in turn damages the fruit inside.

[0003] Therefore, we propose a high-strength fruit printing packaging box to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a high-strength fruit printing packaging box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-strength fruit printing packaging box includes a base plate, side plates, a first panel, a back plate, a top plate, and a second panel. The side plates are symmetrically connected to the left and right sides of the base plate, and the first panel is connected to the front side of the base plate. The back plate is connected to the rear side of the base plate, and the top plate is connected to the back plate. The second panel is connected to the front side of the top plate. Both the upper and lower sides of the side plates are bent inward to form an n-shaped portion. After the box is folded, the n-shaped portions protrude from the base plate and the top plate, respectively. The corresponding n-shaped portions on the side plates have symmetrical perforations, and support rods are inserted into the perforations. The n-shaped portions on the upper side of the side plates are bent inward to form a U-shaped portion. The base plate has several vertically intersecting horizontal and vertical partitions arranged inside. The two ends of the horizontal partitions have symmetrical protrusions for inserting into the n-shaped portions. The upper surface of the horizontal partitions near the protrusions also has a groove for the U-shaped portions to be inserted into.

[0007] In a further embodiment, a groove is provided on one side of the panel, and a handle is connected inside the groove.

[0008] In a further embodiment, the top plate is symmetrically connected with side inserts on its left and right sides, and the side inserts are used to insert into the U-shaped groove of the U-shaped part.

[0009] In a further embodiment, the left and right sides of the second panel are symmetrically connected with face plates, and the face plates are used to insert into the front port of the side panel.

[0010] In a further embodiment, the front of the second panel is provided with a slot, and the size of the slot is 3-5mm larger than the size of the recess.

[0011] In a further embodiment, the upper end face of the transverse partition is uniformly provided with a slot 1 for inserting the longitudinal partition along the length direction, and the lower end face of the longitudinal partition is uniformly provided with a slot 2 for inserting the transverse partition along the length direction.

[0012] In a further embodiment, the heights of the transverse and longitudinal partitions are equal and equal to the distance between the bottom and top plates of the box after folding, and the length of the longitudinal partition is equal to the distance between the front and back plates of the box after folding.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a design where, after the packaging box is folded, the n-shaped portion of the side panel protrudes beyond the top and bottom panels. This allows the n-shaped portion to provide support when the boxes are stacked, reducing the possibility of contact between the top and bottom panels of adjacent boxes and thus minimizing damage to the fruit. Furthermore, the support rods enhance the support strength between the side panels, while the transverse partitions strengthen the support strength of the side panels themselves, resulting in a stronger overall packaging box that is less prone to deformation and provides better protection for the fruit inside.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5A high-strength fruit packaging box is made of corrugated cardboard. During production, custom patterns can be printed on the box surface as needed. The box includes a base plate 1, side plates 2, front panel 3, back plate 4, top plate 5, and second front panel 6. Side plates 2 are symmetrically connected to the left and right sides of the base plate 1, front panel 3 is connected to the front of the base plate 1, back plate 4 is connected to the rear of the base plate 1, top plate 5 is connected to the back plate 4, and second front panel 6 is connected to the front of the top plate 5. The box folds into a […]. The box has a rectangular structure. Panel 2 (6) is attached to panel 1 (3). Panel 1 (3) corresponds to the back panel (4), and the top panel (5) corresponds to the bottom panel (1). The two side panels (2) correspond to each other. Both sides of the side panels (2) are bent inward to form n-shaped parts (21). When the box is folded, the upper n-shaped part (21) protrudes from the upper surface of the top panel (5), and the lower n-shaped part (21) protrudes from the lower surface of the bottom panel (1). Multiple sets of perforations (23) are symmetrically formed on the right side of the left n-shaped part (21) and the left side of the right n-shaped part (21). Each hole 23 has a support rod 9 inserted into it. The support rod 9 supports the space between the two side plates 2, increasing the support strength. After the top plate 5 is folded, the support rod 9 is inserted, and the support rod 9 does not contact the top plate 5. The support rod 9 under the bottom plate 1 can be installed in advance. The n-shaped part 21 on the upper side of the side plate 2 is bent inward to form a U-shaped part 22. The bottom plate 1 has several transverse partitions 7 arranged at equal intervals along the longitudinal direction, and several longitudinal partitions 8 arranged at equal intervals along the transverse direction. The transverse partitions 7 and longitudinal partitions 8 are perpendicular to each other. The internal space of the box is divided into several independent areas to facilitate the separate storage of fruits and reduce the problem of mutual compression due to shaking during transportation. The two ends of the partition plate 7 are symmetrically provided with protrusions 71, which are used to insert into the n-shaped part 21 to provide support for the n-shaped part 21. The upper end surface of the partition plate 7 is also provided with a groove 72 near the protrusions 71, and the groove 72 is used for the U-shaped part 22 to be inserted to provide support for the U-shaped part 22, further enhancing the support strength of the side plate 2.

[0025] Specifically, the upper end face of the transverse partition 7 is evenly provided with slots 73 for inserting the longitudinal partition 8 along the length direction, and the lower end face of the longitudinal partition 8 is evenly provided with slots 81 for inserting the transverse partition 7 along the length direction, so that the transverse partition 7 and the longitudinal partition 8 can be cross-assembled. The height of the transverse partition 7 and the longitudinal partition 8 is equal and equal to the distance between the bottom plate 1 and the top plate 5 after the box is folded, thus forming a supporting frame between the bottom plate 1 and the top plate 5. The length of the longitudinal partition 8 is equal to the distance between the front panel 3 and the back plate 4 after the box is folded, thus forming a supporting frame between the front panel 3 and the back plate 4, which provides better support stability and makes the surface of the packaging box less prone to collapse.

[0026] Furthermore, panel 1 3 has a groove 32 on its front side, and a handle 31 is connected inside the groove 32. Panel 2 6 has a slot 62 on its front side, and the size of the slot 62 is 3-5mm larger than the size of the groove 32. When panel 2 6 is fastened to the outside of panel 1 3, the handle 31 can pass through the slot 62 of panel 2 6, making it convenient for the user to lift the packaging box.

[0027] To facilitate folding, side inserts 51 are symmetrically connected to the left and right sides of the top plate 5, and the side inserts 51 are used to insert into the U-shaped groove of the U-shaped part 22. The front inserts 61 are symmetrically connected to the left and right sides of the second panel 6, and the front inserts 61 are used to insert into the front port of the side plate 2, so that the packaging box can be folded completely.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity.
