Description

Technical Field

[0001] The invention relates to the technical field of cargo packaging, in particular to a buffering and shockproof packaging carton. Background Art

[0002] With the rapid development of the economy, the quality of life of the Chinese people has been significantly improved, and the demand for imported fruits has also increased year by year. Most of the imported fruits are transported by sea. During the sea transportation, the hull shakes due to wind and waves, which in turn causes the fruits transported on the ship to shake or vibrate. In order to ensure that the hull shaking does not cause economic losses in the transportation of fruits, the boxes loaded with fruits need to be cushioned and shockproofed.

[0003] Among many imported fruits, cherries are undoubtedly among the best, especially those imported from Chile. They are picked from trees, packed in boxes, and then shipped to my country by long-distance sea transportation. Finally, they are distributed to various places by Chinese fruit wholesalers. Cherries will inevitably be subjected to vibration and impact during transportation. In order to maintain the freshness of cherries, producers will retain a section of cherry branches when picking, and quantitatively pack them in plastic bags and seal them with nitrogen. In order to reduce costs, ordinary square cartons are usually used for packaging. In addition to the space occupied by the plastic bag, cushioning materials are also added to achieve the effect of cushioning and shock absorption, so that the plastic bag packaging is well fixed, and the overall cushioning and shock absorption effect is good.

[0004] However, when the cherries were distributed to consumers, they were still not fresh and not the same as the goods. The main reason was that the long-term bumps caused the cherries to interact with the branches, or the adjacent cherries collided with each other, resulting in uneven pits on the cherry flesh. These pits not only accelerated the volatilization and oxidation of water, but also because the quantitative cherries in the packaging bag were stacked vertically, the gravity of the upper cherries squeezed the lower cherries, causing the size of the cherries to decrease. The continuous shaking during transportation caused cherries of different sizes to exchange positions, and large cherries were repeatedly squeezed. In the end, the cherries received by the customers became dull and small fruits compared to the plump and rosy cherries when the order was placed, resulting in the phenomenon of not the same as the goods. Fruit wholesalers call this phenomenon "mechanical damage."

[0005] Therefore, in order to solve the above problems, a cushioning and shockproof packaging carton is proposed. Summary of the invention

[0006] The object of the present invention is to provide a buffering and shockproof packaging carton, which solves the problems of mechanical damage caused by the interaction between cherries or cherry tree branches and cherries due to the bumping during transportation, as well as the mechanical damage caused by the position exchange and gravity extrusion of cherries in the upper and lower layers; by arranging a top and bottom box with a regular hexagonal prism shape and a first paper separator, a second paper separator, and a third paper separator to eliminate the longitudinal pressure in layers, the second paper separator is provided with a second honeycomb upper stand and a second honeycomb lower stand in the shape of a regular hexagonal prism on the upper and lower sides, and an annular buffer bag, a first conical hole, and a second conical hole are arranged inside the two, so that each cherry can be separated without affecting the transportation efficiency and sealing, and it is ensured that the longitudinal cherry tree branches of the cherry movement do not interact with the cherries at all times and the longitudinal pressure between the cherries is eliminated, and less buffer material is used in the horizontal direction to reduce the possibility of interaction between cherries and collision of cherries with cardboard.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A buffering and shockproof packaging carton comprises an outer paper shell, an inner paper shell, a first paper separator, a second paper separator and a third paper separator. The inner paper shell is installed inside the outer paper shell, the first paper separator is installed at the bottom of the inner paper shell, a plurality of the second paper separators are installed on the upper end of the first paper separator, the third paper separator is installed on a plurality of the second paper separators and cooperates with the outer paper shell. The second paper separator comprises a second corrugated cardboard, a second honeycomb upper stand and a second honeycomb lower stand. A plurality of the second honeycomb upper stands are evenly arranged on the upper side of the second corrugated cardboard, a plurality of the second honeycomb lower stands are evenly arranged on the lower side of the second corrugated cardboard, and an annular buffer bag is installed inside the second honeycomb upper stand and the second honeycomb lower stand.

[0009] Preferably, the second corrugated paperboard includes a second corrugated paper strip, a second upper paperboard, and a second lower paperboard, wherein the second upper paperboard is installed on the upper side of the second corrugated paper strip, and the second lower paperboard is installed on the lower side of the second corrugated paper strip.

[0010] It can be seen that the second corrugated paper strip is located between the second upper paperboard and the second lower paperboard. When the box body is subjected to longitudinal extrusion or impact force, the second corrugated paper strip buffers the impact by converting the extrusion force into a stretching of its own length, while ensuring that the movement displacement of the second upper paperboard and the second lower paperboard changes little, thereby avoiding the misalignment of the second honeycomb upper position and the second honeycomb lower position on the side close to the two adjacent second paper separators due to sudden longitudinal impact, thereby preventing damage to the goods; in addition, when the longitudinal stress is concentrated, the second corrugated paper board can effectively and evenly disperse the stress, and achieve stress dispersion through its longitudinal amplitude. When the packing encounters a lateral impact force, and the impact force acts from any of the six directions of the packaging box, two situations will occur: First, the impact force diffuses along the direction of the corrugated strip, causing the crests and troughs of the second corrugated strip to become higher, squeezing the second upper cardboard and the second lower cardboard, and then acting on the second honeycomb upper position and the second honeycomb lower position, making the transported goods more stable and reducing shaking; Second, when the impact force does not diffuse along the direction of the second corrugated strip, the deformation resistance in this direction is quite strong, and the deformation of the cardboard is gradually diffused through the height changes of the crests and troughs of the second corrugated strip.

[0011] Preferably, a first conical hole is formed through the second upper paperboard, and the first conical hole is coaxial with the second honeycomb upper vertical position in the longitudinal direction, and a second conical hole is formed through the second lower paperboard, and the second conical hole is coaxial with the second honeycomb lower vertical position in the longitudinal direction, and the aperture of the first conical hole is larger than that of the second conical hole.

[0012] It can be seen that the second upper cardboard is the position for storing cherries when the packaging box is placed upright, and the cherries are placed on the annular buffer bag inside the second honeycomb upper stand; during longitudinal vibration, the cherries may contact the second upper cardboard, and the contact between the flat surface and the curved surface may cause damage to the cherries; in order to solve this problem, a first conical hole is designed, and its shape is combined with the shape of the cherries, so that the curved surfaces are in contact with each other, effectively reducing the damage to the cherries caused by vibration; at the same time, the contact between the cherries and the second corrugated paper strip under the first conical hole is also conducive to energy transfer, and the lateral stretching of the corrugated strip provides a better buffer space for the cherries. The second conical hole has a smaller diameter and is used to store the upper branches of the cherries; there are annular buffer bags on the upper and lower parts of the cherries, and the branches of the upper part pass through the annular buffer bag and enter the second conical hole; the trough on the upper side of the second conical hole limits the lateral shaking of the branches. If the branches do not enter the trough, they will also move along the non-diffusion direction of the crest. At the same time, the second conical surface limits the movement, so as to separate the cherries while ensuring that the branches of the cherries will not be damaged by stress.

[0013] Preferably, the height of the second honeycomb upper position is smaller than that of the second honeycomb lower position, and the matching distance between the second honeycomb upper position and the second honeycomb lower position adjacent to the second paper separator is always smaller than the cross-sectional diameter of the annular buffer bag.

[0014] The second honeycomb upper position is where cherries are stored when the carton is placed upright, and its height is smaller than the radius of the cherries. This design is convenient for loading and for customers to pick up. Relatively speaking, the height of the second honeycomb lower position is larger than the radius of the cherries to cope with the possible rolling of the carton during transportation. When the cherries are inverted and enter the second honeycomb lower position, their position can be restricted laterally to reduce the possibility of lateral movement of the cherries, thereby reducing the risk of collision. The second honeycomb upper position cooperates with the second honeycomb lower position to confine the cherries to a smaller range that can vibrate longitudinally and move laterally. The distance requirement of this coordination ensures that the annular buffer bag is always attached to the upper and lower ends of the cherries and will not be detached.

[0015] Preferably, the second honeycomb upper stand comprises square paper pieces and three-dimensional corrugated paper strips, the three-dimensional corrugated paper strips are installed between two square paper pieces, and the square paper pieces are distributed in a regular hexagon, and the second honeycomb upper stand has the same structure as the second honeycomb lower stand.

[0016] By adopting the above scheme, the square paper pieces are independent of each other and are evenly arranged on the second upper paperboard; such a layout ensures that when the packaging box is slightly disturbed in the longitudinal direction, it is impacted or squeezed in the longitudinal direction, and the force is transmitted to the square paper pieces, causing a slight disturbance change. This change causes the square paper pieces to gather inward to form a hexagonal shape, thereby better limiting the movement of cherries between the annular buffer bags and exerting better shock absorption and buffering effects. The longitudinal disturbance change of the square paper pieces will also cause the three-dimensional corrugated paper strips to stretch; the three-dimensional corrugated paper strips connect all the square paper pieces on the surface to form their own stable hexagonal structure. This structure allows the cherries to stick to the annular buffer bags whether they move longitudinally or laterally, further reducing the damage to the cherries caused by vibration and impact.

[0017] Preferably, the first paper separator includes a first corrugated cardboard and a first honeycomb stand, the first honeycomb stand is mirror-imaged on the upper and lower sides of the first corrugated cardboard, the first conical hole is located on the upper side of the first corrugated cardboard and is coaxial with the first honeycomb stand, and the annular buffer bag is located on the upper side of the first conical hole.

[0018] By adopting the above scheme, the first paper separator is located at the bottom of the inner shell, and cherries are only placed on the upper side of the first paper separator; when the box is placed upright, all the longitudinal weight is gathered at the bottom; there is no difference between the first honeycomb stand on the upper and lower sides of the first corrugated cardboard, and the height of the first honeycomb stand for storing cherries in the upright position is less than the radius of the cherries; the first honeycomb stand on the lower side of the first corrugated cardboard can withstand a smaller deformation to support the overall longitudinal weight; no holes are set on the lower side of the first corrugated cardboard, so as to ensure that the force-bearing area of ​​the longitudinal pressure is evenly distributed, thereby avoiding damage to the bottom of the inner shell due to stress concentration.

[0019] Preferably, the third paper separator includes a third corrugated cardboard, a third honeycomb upper stand, and a third honeycomb lower stand, the third honeycomb upper stand is arranged on the upper side of the third corrugated cardboard, the third honeycomb lower stand is arranged on the lower side of the third corrugated cardboard, the annular buffer bag is located inside the third honeycomb lower stand, the second conical hole is located on the lower side of the third corrugated cardboard and above the annular buffer bag, and the height of the third honeycomb upper stand is lower than that of the third honeycomb lower stand.

[0020] By adopting the above scheme, the third paper separator is located at the top of the packaging box and cooperates with the plane of the paper shell; therefore, no cherries are placed on the upper side of the third paper separator; in order to ensure that the top joint does not deform when subjected to impact or pressure, the third honeycomb upper position is designed to be lower to reduce the possibility of deflection and deformation; in addition, there is no hole on one side of the third corrugated cardboard, which allows the force to be evenly distributed when subjected to pressure or impact, effectively reducing the risk of deformation. In extreme cases, such as when the carton is inverted, the third honeycomb upper position is required to bear the entire weight; at the same time, the third honeycomb lower position is designed to be higher to ensure that the position of the cherries is limited when the packaging box rolls, and cooperates with the annular buffer bag to reduce impact, thereby achieving a buffering and shock-absorbing effect; the use of the annular buffer bag in conjunction with the second conical hole can constrain the cherry branches stored on the top layer laterally to avoid stress damage to the cherries.

[0021] Preferably, the paper inner shell comprises a body and separators, the separators are arranged in a circular array on the body, and the paper inner shell is in the shape of a regular hexagonal column.

[0022] By adopting the above scheme, the cross-section of the paper inner shell is designed to be a regular hexagon. Compared with traditional square and rectangular packaging boxes, this design has stronger longitudinal compression resistance. Specifically, the square packaging box has only four supporting sides, while the regular hexagonal top and bottom box has twelve supporting sides. This structure makes it unnecessary to wrap a large amount of disposable tape around the hexagonal packaging box in normal use, thereby achieving a more environmentally friendly purpose. Under the same stacking of goods, the hexagonal packaging box can stack more goods, thereby improving transportation efficiency. The existence of the partition block is not only used to position the package and facilitate customers to pick up goods, but also horizontally limits the possibility of misalignment of the first partition paper tray, the second partition paper tray, and the third partition paper tray. This design not only ensures the relatively independent buffering of the internal cherries, but also enhances the longitudinal anti-extrusion ability. At the same time, the height of the partition block is consistent with the inner and outer boxes, ensuring that the impact on the internal partition paper tray is small during longitudinal extrusion or impact, thereby ensuring the cherries. The cross-section of the intact paper inner shell is designed to be a regular hexagon, which has stronger longitudinal compression resistance than traditional square and rectangular packaging boxes. Specifically, the square packaging box has only four supporting sides, while the regular hexagonal top and bottom box has twelve supporting sides. This structure eliminates the need to wrap a large amount of disposable tape around the hexagonal packaging box during normal use, thereby achieving a more environmentally friendly purpose. Under the same stacking of goods, the hexagonal packaging box can stack more goods, thereby improving transportation efficiency. The presence of the divider is not only used to position the package and facilitate customers to pick up goods, but also laterally limits the possibility of misalignment of the first, second, and third paper trays. This design not only ensures relatively independent buffering of the internal cherries, but also enhances the longitudinal anti-extrusion ability. At the same time, the height of the divider is consistent with the inner and outer boxes, ensuring that the impact on the internal divider paper tray is smaller during longitudinal extrusion or impact, thereby ensuring that the cherries are intact.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. A second corrugated paper strip is provided on the second corrugated paper board, and the second corrugated paper strip exists between the second upper paper board and the second lower paper board. When the box body is subjected to longitudinal extrusion or impact force, the second corrugated paper strip buffers the impact by converting the extrusion force into the stretching of its own length, and at the same time ensures that the movement displacement change of the second upper paper board and the second lower paper board is small, so as to avoid the misalignment of the second honeycomb upper position and the second honeycomb lower position on the side close to the two adjacent second paper separators due to sudden longitudinal impact, thereby preventing damage to the goods; in addition, when the longitudinal stress is concentrated, the second corrugated paper board can effectively and evenly disperse the stress, and achieve Stress dispersion. When the packaging box encounters a lateral impact force, and the impact force acts from any of the six directions of the packaging box, two situations will occur: First, the impact force diffuses along the direction of the corrugated strip, causing the crests and troughs of the second corrugated strip to become higher, squeezing the second upper cardboard and the second lower cardboard, and then acting on the second honeycomb upper position and the second honeycomb lower position, making the transported goods more stable and reducing shaking; Second, when the impact force does not diffuse along the direction of the second corrugated strip, the deformation resistance in this direction is quite strong, and the deformation of the cardboard is gradually diffused through the height changes of the crests and troughs of the second corrugated strip.

[0025] 2. A through conical hole is specially designed on the second upper cardboard, which is called the first conical hole. Similarly, a through conical hole is also designed on the second lower cardboard, which is called the second conical hole. The second upper cardboard is where the cherries are stored when the packaging box is placed upright. The cherries are placed on the annular cushioning bag inside the second honeycomb upper stand. During longitudinal vibration, the cherries may come into contact with the second upper cardboard, and the contact between the flat surface and the curved surface may cause damage to the cherries. In order to solve this problem, the first conical hole is designed, and its shape matches the appearance of the cherries, so that the curved surfaces are in contact with each other, which effectively reduces the damage to the cherries caused by vibration. At the same time, the cherries The cherries are in contact with the second corrugated paper strip under the first conical hole, which is beneficial to the transfer of energy, and the lateral stretching of the corrugated strip provides a better buffer space for the cherries. The second conical hole has a smaller diameter and is specifically used to store branches on the cherries. The upper and lower ends of the cherries are equipped with annular buffer bags, and the branches in the upper part pass through the annular buffer bags and enter the second conical hole. The trough on the upper side of the second conical hole limits the lateral shaking of the branches. If the branches do not enter the trough, they will also move along the non-diffusion direction of the crest. At the same time, the second conical surface limits the movement of the branches, realizes the separation of the cherries, and ensures that the cherry branches will not be damaged by stress.

[0026] 3. By arranging partition blocks on the packaging box body, these partition blocks are not only used to position the package and facilitate customers to pick up the goods, but also play a role in laterally limiting the misalignment of the first paper partition tray, the second paper partition tray, and the third paper partition tray; such a design not only ensures that the cherries inside can be relatively independently buffered and protected, but also enhances the longitudinal anti-extrusion ability of the packaging box; at the same time, the height of the partition blocks is consistent with the inner and outer boxes, so that when squeezed or impacted in the longitudinal direction, the impact on the internal partition paper tray is smaller, thereby protecting the cherries from damage and ensuring that they are intact.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] See also Figures 1 to 8 The present invention provides a cushioning and shockproof packaging carton, and the technical solution is as follows:

[0038] For details, please refer to Figure 1 , Figure 2 and Figure 3 A buffering and shockproof packaging carton comprises a paper outer shell 1, a paper inner shell 2, a first paper partition plate 3, a second paper partition plate 4, and a third paper partition plate 5. The paper inner shell 2 is installed inside the paper outer shell 1, the first paper partition plate 3 is installed at the bottom of the paper inner shell 2, a plurality of second paper partition plates 4 are installed on the upper end of the first paper partition plate 3, the third paper partition plate 5 is installed on a plurality of second paper partition plates 4, and cooperates with the paper outer shell 1. The second paper partition plate 4 comprises a second corrugated cardboard 41, a second honeycomb upper stand 42, and a second honeycomb lower stand 43. A plurality of second honeycomb upper stands 42 are evenly arranged on the upper side of the second corrugated cardboard 41, and a plurality of second honeycomb lower stands 43 are evenly arranged on the lower side of the second corrugated cardboard 41. Annular buffer bags 6 are installed inside the second honeycomb upper stands 42 and the second honeycomb lower stands 43.

[0039] As an embodiment of the present invention, refer to Figure 2 , Figure 4 and Figure 5The second corrugated paperboard 41 includes a second corrugated paper strip 411, a second upper paperboard 412, and a second lower paperboard 413. The second upper paperboard 412 is installed on the upper side of the second corrugated paper strip 411, and the second lower paperboard 413 is installed on the lower side of the second corrugated paper strip 411. The second corrugated paper strip 411 is located between the second upper paperboard 412 and the second lower paperboard 413. When the box body is subjected to longitudinal extrusion or impact force, the second corrugated paper strip 411 buffers the impact by converting the extrusion force into a stretching of its own length, while ensuring that the movement displacement of the second upper paperboard 412 and the second lower paperboard 413 changes little, thereby avoiding the misalignment of the second honeycomb upper stand 42 and the second honeycomb lower stand 43 on the near side of the two adjacent second paper separators 4 due to sudden longitudinal impact, thereby To prevent damage to the goods; in addition, when the longitudinal stress is concentrated, the second corrugated paperboard 41 can effectively and evenly disperse the stress, and achieve stress dispersion through its longitudinal amplitude. When the packaging box encounters a lateral impact force, and the impact force acts in any of the six directions of the packaging box, two situations will occur: First, the impact force diffuses along the direction of the corrugated strip, making the crests and troughs of the second corrugated strip higher, squeezing the second upper paperboard 412 and the second lower paperboard 413, and then acting on the second honeycomb upper stand 42 and the second honeycomb lower stand 43, making the transported goods more stable and reducing shaking; second, when the impact force does not diffuse along the direction of the second corrugated paper strip 411, the deformation resistance in this direction is quite strong, and the deformation of the paperboard is also transmitted through the second corrugated paper strip 4 The height changes of the peaks and troughs of 11 gradually spread out, a first conical hole 7 is penetrated through the second upper paperboard 412, and the first conical hole 7 is longitudinally coaxial with the second honeycomb upper stand 42, a second conical hole 8 is penetrated through the second lower paperboard 413, and the second conical hole 8 is longitudinally coaxial with the second honeycomb lower stand 43, the aperture of the first conical hole 7 is larger than that of the second conical hole 8, the second upper paperboard 412 is the position for storing cherries when the packaging box is placed upright, and the cherries are placed on the annular buffer bag 6 inside the second honeycomb upper stand 42; during longitudinal vibration, the cherries may contact the second upper paperboard 412, and the contact between the plane and the curved surface may cause damage to the cherries; in order to solve this problem, a first conical hole is designed, and its shape is compound of cherries The shape of the cherry makes the curved surfaces contact with each other, effectively reducing the damage of the cherries caused by vibration; at the same time, the contact between the cherries and the second corrugated paper strip 411 under the first conical hole is also conducive to energy transfer. The lateral stretching of the corrugated strip provides a better buffer space for the cherries. The second conical hole has a smaller diameter and is used to store the upper branches of the cherries; there are annular buffer bags 6 on the upper and lower parts of the cherries, and the branches in the upper part pass through the annular buffer bags 6 and enter the second conical hole; the trough on the upper side of the second conical hole limits the lateral shaking of the branches. If the branches do not enter the trough, they will also move along the non-diffusion direction of the crest. At the same time, the second conical surface limits the movement, so as to separate the cherries while ensuring that the branches of the cherries will not be damaged by stress.

[0040] As an embodiment of the present invention, refer to Figure 2 , Figure 3 and Figure 4 The height of the second honeycomb upper position 42 is smaller than that of the second honeycomb lower position 43. The matching distance between the second honeycomb upper position 42 and the second honeycomb lower position 43 of the adjacent second paper separator 4 is always smaller than the cross-sectional diameter of the annular buffer bag 6. The second honeycomb upper position 42 is the position for storing cherries when the carton is placed upright, and its height is smaller than the radius of the cherries. Such a design is convenient for both loading and picking up by customers. Relatively speaking, the height of the second honeycomb lower position 43 is larger than the radius of the cherries to cope with the possible rolling of the carton during transportation. When the cherries are inverted and enter the second honeycomb lower position 43, their position can be restricted laterally to reduce the possibility of lateral movement of the cherries, thereby reducing the risk of collision. The upper and lower matching of the second honeycomb upper position 42 and the second honeycomb lower position 43 restricts the cherries to a smaller range that can both vibrate longitudinally and move laterally. Such matching distance requirement ensures that the annular buffer bag 6 is always attached to the upper and lower ends of the cherries and will not be detached.

[0041] As an embodiment of the present invention, refer to Figure 1 , Figure 3 , Figure 5 and Figure 6The second honeycomb upper stand 42 includes a square paper piece 421 and a three-dimensional corrugated paper strip 422. The three-dimensional corrugated paper strip 422 is installed between two square paper pieces 421, and the square paper pieces 421 are distributed in a regular hexagon. The second honeycomb upper stand 42 has the same structure as the second honeycomb lower stand 43. The square paper pieces 421 are independent of each other and are evenly arranged on the second upper paperboard 412. Such a layout ensures that when the packaging box is slightly disturbed in the longitudinal direction, the longitudinal impact or extrusion force is transmitted to the square paper piece 421, so that The slight disturbance change causes the square paper pieces 421 to gather inwards to form a hexagonal shape, thereby better limiting the movement of the cherries between the annular cushioning bags 6 and achieving better shock absorption and cushioning effects. The longitudinal disturbance change of the square paper pieces 421 also causes the three-dimensional corrugated paper strips 422 to stretch; the three-dimensional corrugated paper strips 422 connect all the square paper pieces 421 on the surface to form their own stable hexagonal structures. This structure allows the cherries to move vertically or horizontally. When the box is moved, it can be tightly attached to the annular buffer bag 6 to further reduce the damage to the cherries caused by vibration and impact. The first paper separator 3 includes a first corrugated cardboard 31 and a first honeycomb stand 32. The first honeycomb stand 32 is mirror-imaged on the upper and lower sides of the first corrugated cardboard 31. The first conical hole 7 is located on the upper side of the first corrugated cardboard 31 and is coaxial with the first honeycomb stand 32. The annular buffer bag 6 is located on the upper side of the first conical hole 7. The first paper separator 3 is located at the bottom of the inner shell, and the cherries are only placed on the upper side of the first paper separator 3; when the box is placed forward, all the longitudinal weight is concentrated at the bottom; there is no difference between the first honeycomb stand 32 on the upper and lower sides of the first corrugated cardboard 31, and the height of the first honeycomb stand 32 for forward storage of cherries is less than the radius of the cherries; the first honeycomb stand 32 on the lower side of the first corrugated cardboard 31 can withstand a small deformation to support the overall longitudinal weight; no holes are set on the lower side of the first corrugated cardboard 31, so as to ensure that the force-bearing area of ​​the longitudinal pressure is evenly distributed to avoid damage to the bottom of the inner shell due to stress concentration.

[0042] As an embodiment of the present invention, refer to Figure 1 , Figure 3 and Figure 7The third paper separator 5 includes a third corrugated board 51, a third honeycomb upper stand 52, and a third honeycomb lower stand 53. The third honeycomb upper stand 52 is arranged on the upper side of the third corrugated board 51, and the third honeycomb lower stand 53 is arranged on the lower side of the third corrugated board 51. The annular buffer bag 6 is located inside the third honeycomb lower stand 53. The second conical hole 8 is located on the lower side of the third corrugated board 51 and above the annular buffer bag 6. The height of the third honeycomb upper stand 52 is lower than that of the third honeycomb lower stand 53. The third paper separator 5 is located at the top of the packaging box and cooperates with the plane of the paper shell 1. Therefore, no cherries are placed on the upper side of the third paper separator 5. In order to ensure that the top joint does not occur when it is impacted or pressurized The third honeycomb upper position 52 is designed to be lower to reduce the possibility of deflection and deformation; in addition, one side of the third corrugated cardboard 51 is not opened, which allows the force to be evenly distributed when subjected to pressure or impact, effectively reducing the risk of deformation. In extreme cases, such as when the carton is inverted, the third honeycomb upper position 52 is required to bear the entire weight; at the same time, the third honeycomb lower position 53 is designed to be higher to ensure that the position of the cherries is limited when the packaging box rolls, and cooperates with the annular buffer bag 6 to reduce impact and achieve the effect of buffering and shock absorption; the use of the annular buffer bag 6 in conjunction with the second conical hole can restrain the cherry branches stored on the top layer in the horizontal direction to avoid stress damage to the cherries.

[0043] As an embodiment of the present invention, refer to Figure 1 and Figure 8 The paper inner shell 2 includes a body 21 and a separator 22. The separator 22 is arranged in a circular array on the body 21. The paper inner shell 2 is a regular hexagonal column. The cross-section of the paper inner shell is designed to be a regular hexagon. Compared with traditional square and rectangular packaging boxes, this design has stronger longitudinal compression resistance. Specifically, the square packaging box has only four supporting sides, while the regular hexagonal top and bottom box has twelve supporting sides. This structure makes it unnecessary to wrap a large amount of disposable tape around the hexagonal packaging box in normal use, thereby achieving a more environmentally friendly purpose. In the case of accumulating goods, the hexagonal packaging box can stack more goods, thereby improving transportation efficiency; the existence of the dividing block 22 is not only used to position the package and facilitate customers to pick up goods, but also horizontally limits the possibility of misalignment of the first paper separation tray 3, the second paper separation tray 4, and the third paper separation tray 5; such a design not only ensures the relatively independent buffering of the internal cherries, but also enhances the longitudinal anti-extrusion ability; at the same time, the height of the dividing block 22 is consistent with the inner and outer box bodies, ensuring that during longitudinal extrusion or impact, the impact on the internal dividing paper tray is small, thereby ensuring that the cherries are intact.

[0044] Usage process: store cherries on the first honeycomb stand 32 on the upper layer of the first corrugated cardboard 31, place the cherries upright inside the first honeycomb stand 32 with the cherry branches facing upward, place an annular buffer bag 6 at the position of the cherry branches, and position the first paper separator 3 at the bottom of the paper inner shell 2 through the dividing block 22 on the paper inner shell 2, and place the cherries forward on the annular buffer bag 6 inside the second honeycomb upper stand 42 with the cherry branches facing vertically upward, and evenly place them on each second honeycomb upper stand 42. The annular buffer bag 6 inside the second honeycomb lower stand 43 has been placed on the top of the cherries placed on the first honeycomb stand 32 at the bottom layer, so as to stack the second paper separator 4 and the cherries, and finally the third paper separator 5 is capped with the dividing block 22 on the paper inner shell 2 to complete the cover with the paper outer shell 1 to complete the loading.

[0045] Usage during transportation: when there is external longitudinal pressure, the paper outer shell 1 and the paper inner shell 2 jointly support it, and the support is guaranteed by the partition block 22. Although the pressure shock is large, the partition cardboard can still provide support and protection, and the cherries will not be damaged. When subjected to lateral impact, the hexagonal prism shape will balance the impact to each surface, and no stress concentration will occur. The deformation caused fully protects the cherries. When shaking longitudinally, the cherries are within the spacing between the partition cardboards, and the longitudinal position is initially limited. The presence of the annular buffer bag 6 further limits the movement position, and the annular buffer bag 6 and the cherries are in curved surface to curved surface contact, so that the buffering and shock absorption effects are optimal. At the same time, it is ensured that there is no curved surface to flat surface contact with the cardboard in the horizontal direction, reducing the possibility of damage to the cherries. The setting of the first conical hole 7 and the second conical hole 8 ensures that the movement position range of the cherries in the longitudinal cherry tree branch is fixed to ensure that it does not act on the cherries, and the contact of the flesh at the bottom of the cherries is also curved surface to curved surface contact, which will not damage the cherries.
