Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable packaging box technology, and more specifically, it relates to a crush-resistant fruit and vegetable packaging box. Background Technology

[0002] Currently, fruits are packaged with a layer of shock-proof material during transportation. For example, each apple is covered with a foamed fruit net before transportation to prevent damage during the process.

[0003] Application number CN202020000709.2 discloses a multifunctional fruit packaging box, the key technical points of which are: it includes an upper box lid, a lower box body and a film; the upper surface of the upper box lid has several round through holes; the four corners of the outer side wall of the upper box lid are fixedly connected with reinforcing posts; the inner side wall of the upper box lid has stepped grooves; the four corners of the inner side wall of the upper box lid are embedded with fixing strips; the interior of the lower box body has several fruit slots; the upper surface of the lower box body is fixedly connected with several conical truncated cones; the film is fixedly connected to the upper surface of the conical truncated cones; and the two ends of the lower surface of the lower box body have handle grooves for easy picking or placing.

[0004] The comparison document describes a method where a thin film is placed on the upper surface of the box, and the fruit is placed on top of the film. Because there is a certain gap between the film and the fruit slot, the entire packaging box has a shock-absorbing effect during transportation. In addition, the film can buffer the pressure when the fruit is hit, protecting the fruit from deformation. However, there is no cushioning structure between the top of the fruit and the top of the box lid after the fruit is placed in the packaging box. This can cause varying degrees of damage to the upper part of the fruit when it is handled or stacked.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a crush-resistant fruit and vegetable packaging box.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a crush-resistant fruit and vegetable packaging box, including a box body and a lid detachably connected thereto, wherein a plurality of symmetrically arranged upper clamping pieces and lower clamping pieces are placed inside the box body, and a deformation mesh is provided in the central area of ​​each of the upper clamping pieces and the lower clamping pieces, the deformation mesh of the upper clamping pieces and the deformation mesh of the lower clamping pieces are arranged correspondingly, adjacent upper clamping pieces and adjacent lower clamping pieces are detachably connected, and a plurality of limiting pieces are rotatably connected to the inner bottom surface of the box body, and the end of the lower clamping piece abuts against the limiting piece.

[0008] The present invention is further configured such that: the cross-sectional shape of the upper clamping plate and the lower clamping plate is "n" shaped, and the upper clamping plate and the lower clamping plate each include a fixed plate and a bent plate rotatably connected to both sides thereof, and the deformation mesh is fixedly connected to the fixed plate.

[0009] The present invention is further configured such that: the fixing piece is provided with snap-fit ​​grooves on both sides near the bending piece, the two snap-fit ​​grooves are staggered and the length of the two snap-fit ​​grooves is the same as the width of the fixing piece.

[0010] The present invention is further configured such that: a plurality of snap-fit ​​blocks are fixedly connected to the inner top surface of the cover; when the cover is closed on the box, the snap-fit ​​blocks are located in the included angle formed by adjacent upper clamping pieces and abut against the upper clamping pieces.

[0011] The present invention is further configured such that: the limiting plates include several groups of two bent plates with opposite rotation directions used to limit the ends of the two interlocking lower clamping plates from getting close to each other.

[0012] The present invention is further configured such that: a placement groove is provided on the inner bottom surface of the box body, the limiting piece is rotatably connected in the placement groove, and the width of the placement groove is equal to the width of the end of the lower clamping piece.

[0013] The present invention is further configured such that bubble wrap is fixedly connected to the inner top surface of the cover and the inner bottom surface of the box.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] A type of crush-resistant fruit and vegetable packaging box, such as Figures 1-5 As shown, the device includes a box body 1 and a lid 2 detachably connected to it. Both the box body 1 and the lid 2 are made of polyethylene terephthalate (PET). PET has high air permeability, good strength, and chemical corrosion resistance, making the box body 1 safer and more hygienic when storing fruits and vegetables. Several symmetrically arranged upper clamping plates 3 and lower clamping plates 4 are placed inside the box body 1. The upper clamping plates 3 and lower clamping plates 4 are also made of polyethylene terephthalate (PET). A deformation mesh 5 is provided in the central area of ​​both the upper clamping plates 3 and lower clamping plates 4. The deformation mesh 5 serves as a protective sleeve for fruits and vegetables, typically made of polyethylene foam (EPE), which has good shock resistance. The deformation mesh 5 of the upper clamping plates 3 and lower clamping plates 4 can wrap the fruit. The deformation mesh 5 also has deformable properties, better adapting to fruits of different sizes. The deformation mesh 5 of the upper clamping piece 3 and the lower clamping piece 4 are correspondingly set. Adjacent upper clamping pieces 3 and adjacent lower clamping pieces 4 are detachably connected. When wrapping the fruit, the upper clamping pieces 3 and lower clamping pieces 4 can support the fruit. The top and bottom of the fruit are in contact with the deformation mesh 5. When the fruit is small, the upper clamping pieces 3 and lower clamping pieces 4 fix the fruit in the middle of the box body 1, so that the fruit is in a suspended state. In this way, the fruit will not come into contact with the box body 1 and the lid 2 during transportation, improving the fruit transportation efficiency and reducing the fruit transportation loss rate. If the fruit to be transported is larger, the deformation mesh 5 wraps around the outside of the fruit. Even if the top and bottom of the fruit are in contact with the lid 2 and the box body 1, the deformation mesh 5 can still separate the fruit from the packaging box. The shock-absorbing effect of the deformation mesh 5 reduces the damage to the fruit caused by external impacts during handling and ensures the anti-compression effect of the fruit transportation.

[0023] The upper clamping plate 3 and the lower clamping plate 4 have an "n" shaped cross-section. Both the upper clamping plate 3 and the lower clamping plate 4 include a fixed plate 8 and a bent plate 9 rotatably connected to both sides thereon. The deformable mesh 5 is fixedly connected to the fixed plate 8. The fixed plate 8 has snap-fit ​​grooves 7 on both sides near the bent plate 9. The two snap-fit ​​grooves 7 are staggered and their lengths are equal to the width of the fixed plate 8. The outer peripheral wall of the fixed plate 8 has a square cross-section. A through groove is formed inside the fixed plate 8. The outer peripheral wall of the deformable mesh 5 is bonded to the inner wall of the through groove. The fixed plate 8 supports the deformable mesh 5 without hindering its deformation. The fixed plate 8 and the bent plate 9 are integrally injection molded by an injection molding machine. The finished product is pressed to make it bendable. The plastic material itself has the ability to deform, thus forming a bendable piece 9. The snap-fit ​​groove 7 is formed by cutting on the fixing piece 8. The length of the snap-fit ​​groove 7 is equal to half the width of the fixing piece 8. When two upper clamping pieces 3 or two lower clamping pieces 4 are spliced, when two adjacent fixing pieces 8 are snapped together, the end of the first fixing piece 8 with the snap-fit ​​groove 7 is inserted into the end of the second fixing piece 8 with the snap-fit ​​groove 7, and the two snap-fit ​​grooves 7 are staggered. After the assembly is completed, one of the bendable pieces 9 of the first fixing piece 8 is located below the second fixing piece 8, and the bendable piece 9 on the second fixing piece 8 is located below the first fixing piece 8.

[0024] Two adjacent bent pieces 9 form an angle. Several limiting pieces 6 are rotatably connected to the inner bottom surface of the box body 1. The end of the lower clamping piece 4 abuts against the limiting piece 6. A placement groove is opened on the inner bottom surface of the box body 1. The limiting piece 6 is rotatably connected in the placement groove. The width of the placement groove is equal to the width of the end of the lower clamping piece 4. The bent piece 9 is inserted into the placement groove and abuts against the limiting piece 6. The two bent pieces 9 at the ends abut against the inner side wall of the box body 1. The limiting piece 6 prevents the bent piece 9 from sliding. Therefore, the assembled upper clamping piece 3 and lower clamping piece 4 can be fixed in the box body 1, further ensuring the stability of the deformation net 5 wrapping the fruit. This splicing method can better adapt to box bodies 1 of different sizes. When fruit is placed on the fixing piece 8, the pressure exerted by the fruit causes the bent piece 9 to tend to slide to both sides. At this time, the limiting piece 6 will hinder the sliding of the bent piece 9. The heavier the fruit, the more stable the upper clamping piece 3 and lower clamping piece 4 are in fixing the fruit.

[0025] The limiting pieces 6 include several sets of two bent pieces 9 with opposite rotation directions used to limit the ends of the two interlocking lower clamping pieces 4 that are close to each other. Each set of limiting pieces 6 includes two pairs of limiting pieces 6 arranged opposite each other. Several sets are set at the connection position of two adjacent lower clamping pieces 4. Several limiting pieces 6 with different spacing can limit and fix the ends of the lower clamping pieces 4 that are spliced ​​to different angles. The larger the included angle between the two bent pieces 9 that are close to each other after assembly, the smaller the distance between the bottom surface of the fixing piece 8 and the inner bottom surface of the box body 1. When transporting different fruits, the angle of the bent pieces 9 can be adjusted to adapt to the situation, so that after the deformation net 5 wraps the fruit, there is a certain gap between it and the inner bottom surface of the box body 1 and the inner top surface of the lid 2, which reduces the damage to the fruit caused by external impact and also improves the practicality of the structure.

[0026] The inner top surface of the cover 2 is integrally formed with several snap-fit ​​blocks 10. When the cover 2 is closed on the box 1, the snap-fit ​​blocks 10 are located in the included angle formed by the adjacent upper clamping pieces 3 and abut against the upper clamping pieces 3. After the upper clamping pieces 3 and the lower clamping pieces 4 are installed, the snap-fit ​​blocks 10 on the cover 2 abut against the upper clamping pieces 3, restricting the upper clamping pieces 3 from shaking inside the box 1. The inner top surface of the cover 2 and the inner bottom surface of the box 1 are both bonded with bubble wrap 11. The setting of bubble wrap 11 also enhances the anti-compression effect of the box 1 and the cover 2.

[0027] Working principle: Symmetrical upper clamping piece 3 and lower clamping piece 4 are set inside the box body 1. A deformation mesh 5 is set in the central area. The deformation mesh 5 has good shock resistance and deformation capacity. The upper clamping piece 3 and lower clamping piece 4 wrap and support the fruits and vegetables through the deformation mesh 5, so that the fruits and vegetables are suspended and avoid direct contact with the box body 1 and the lid 2, reducing collisions and squeezing during transportation. The upper clamping piece 3 and lower clamping piece 4 are staggered and spliced ​​through the snap-fit ​​groove 7 to form a stable support structure. The bending piece 9 abuts against the limiting piece 6 inside the box body 1 to further fix the position of the clamping piece and ensure that the fruits and vegetables remain stable during transportation. The snap-fit ​​block 10 on the top surface inside the lid 2 abuts against the upper clamping piece 3 to limit the shaking of the upper clamping piece 3 and enhance the stability of the overall structure.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
