Description

Technical Field

[0001] This utility model relates to the field of packaging products, and in particular to a fragile fresh food transport packaging box. Background Technology

[0002] Fragile fresh foods, such as strawberries, cherries, eggs, and glass-bottled sauces, are easily damaged during transportation due to their delicate texture and susceptibility to external forces. Most existing fresh food packaging boxes only use simple foam plastic or paper padding as cushioning materials, and their structures are mostly fixed shapes, making it impossible to provide targeted cushioning based on the actual shape, size, and vulnerable parts of the fragile fresh foods.

[0003] Secondly, some packaging materials experience reduced elasticity and decreased deformation recovery after prolonged use or exposure to significant impacts, resulting in a substantial decline in cushioning performance. For instance, the internal structure of some paper cushioning pads can be damaged after repeated use, rendering them unable to effectively absorb and disperse impact energy, thus increasing the risk of breakage for fragile fresh food during subsequent transportation. Utility Model Content

[0004] The purpose of this utility model is to provide a fragile fresh food transport packaging box, which solves the problems of existing packaging boxes having limited cushioning and protection and being prone to collapse and deformation.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a fragile fresh food transport packaging box, including a box body, the box body is composed of a front end plate, a rear end plate, a bottom plate and two side walls forming an open-top receiving chamber, the front end plate, the rear end plate and the two side walls are integrally bent and connected to the corresponding edges of the bottom plate, and the box body is provided with an inner layer and a foam body.

[0006] The inner layer includes an inner front panel, an inner rear panel, and two inner side panels. The foam is a cavity structure with an open top. The foam is placed inside the box, and the outer contour of the foam matches the inner contour of the box. The inner front panel and inner rear panel are bent inward vertically from the top edges of the front and rear panels, respectively. The two inner side panels are bent inward vertically from the top edges of the two side walls, respectively. The inner front panel, inner rear panel, and two inner side panels extend into the box and form a lateral covering structure for the foam.

[0007] Preferably, the outer walls of the foam body and the front and rear end plates are symmetrically provided with strip grooves. The strip grooves are groove structures that penetrate the thickness of the foam body. The two sides of the inner side plate are slidably inserted into the strip grooves on the corresponding sides, forming a stable insertion structure.

[0008] Preferably, the inner front plate and inner rear plate are bent and placed between the two inner side plates to ensure that the inner front plate and inner rear plate are tightly fitted with the two inner side plates to form a stable and effective lateral covering structure for the foam.

[0009] Preferably, the bottom of the inner cavity of the foam body is provided with an insertion groove, the bottom of the inner rear plate extends downward to form a first extension, and the first extension is inserted into the insertion groove. The bottom of the inner front plate is bent vertically to form an inner lower plate, which is laid flat on the bottom of the inner cavity of the foam body. The edge of the inner lower plate near the inner rear plate is bent vertically downward to form an insertion piece, which is inserted into the insertion groove.

[0010] Preferably, the two side walls of the box are provided with waist-shaped holes, which provide a point of leverage for the handlers, making it easier to handle the packaging box by gripping the waist-shaped holes.

[0011] Preferably, the foam body has grooves on both sides corresponding to the sidewalls, and the inner side plate has a slide rail at the corresponding position of the groove. The inner layer has a partition, and the two sides of the partition are slidably connected in the corresponding groove and slide rail.

[0012] Preferably, the top of the box is provided with a lid, which is a cover structure with an inner cavity at the bottom. The outline of the inner cavity of the lid matches the outer outline of the opening at the top of the box. The lid can be tightly fastened to the top of the box, completely covering the opening at the top of the box, providing sealed protection for fragile fresh food inside the box, and reducing the risk of external dust, moisture, foreign objects and other substances entering the inside of the box.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. This utility model features an inner layer and a foam body inside the box, which work together to form a protective system. The foam body, as the core cushioning component, completely wraps the fresh food, effectively absorbing and dispersing the impact and vibration energy generated during transportation. The inner layer further covers the foam body laterally to prevent it from shaking inside the box and avoids damage to the fresh food due to displacement of the foam body. This double-coverage structure improves the cushioning and shock absorption performance of the packaging box, providing a reliable protective barrier for fragile fresh food.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 5 This embodiment provides a fragile fresh food transport packaging box, including a box body 1. The box body 1 is composed of a front end plate 11, a rear end plate 12, a bottom plate 13 and two side walls 14 forming an open-top receiving chamber. The front end plate 11, the rear end plate 12 and the two side walls 14 are integrally bent and connected to the corresponding edges of the bottom plate 13. The box body 1 is provided with an inner layer 2 and a foam body 3 inside.

[0024] The inner layer 2 includes an inner front panel 21, an inner rear panel 22, and two inner side panels 23. The foam body 3 is a cavity structure with an open top. The foam body 3 is placed inside the box body 1, and the outer contour of the foam body 3 matches the inner contour of the box body 1. The inner front panel 21 and the inner rear panel 22 are bent inward in the vertical direction from the top edges of the front end panel 11 and the rear end panel 12, respectively. The two inner side panels 23 are bent inward in the vertical direction from the top edges of the two side walls 14, respectively. The inner front panel 21, the inner rear panel 22, and the two inner side panels 23 extend into the box body 1 and form a lateral covering structure for the foam body 3.

[0025] The box body 1 adopts a single-sheet cardboard cross-shaped structure, which is bent to form a double layer of protection. The outer box body 1 provides basic strength, while the inner composite structure 2 extends into the foam body 3 to enhance local puncture resistance. The internal chambers of the foam body 3 are customized according to the size and stacking method of fresh food to reduce the relative displacement between the goods and the packaging. The foam absorbs and disperses the impact and vibration energy generated during transportation.

[0026] The outer walls of the foam body 3 and the front end plate 11 and the rear end plate 12 are symmetrically provided with strip grooves 33. The strip grooves 33 are groove structures that penetrate the thickness of the foam body 3. The two sides of the inner side plate 23 are slidably inserted into the strip grooves 33 on the corresponding sides, forming a stable insertion structure. This structure can effectively restrict the movement of the foam body 3 and prevent the foam body 3 from shaking or shifting inside the box 1 due to external forces during transportation.

[0027] The inner front panel 21 and inner rear panel 22 are bent and placed between the two inner side panels 23. The width of the inner front panel 21 and inner rear panel 22 is the same as or slightly smaller than the distance between the two inner side panels 23, so as to ensure that the inner front panel 21 and inner rear panel 22 are tightly fitted with the two inner side panels 23, and together form a stable and effective lateral covering structure for the foam 3, which enhances the limiting and fixing effect on the foam 3 and prevents the foam 3 from shaking in the box 1 during transportation.

[0028] The bottom of the inner cavity of the foam body 3 is provided with an insertion groove 34. The bottom of the inner rear plate 22 extends downward to form a first extension, which is inserted into the insertion groove 34. The bottom of the inner front plate 21 is bent vertically to form an inner lower plate 24. The inner lower plate 24 is laid flat on the bottom of the inner cavity of the foam body 3. The edge of the inner lower plate 24 near the inner rear plate 22 is bent vertically downward to form an insertion piece 25. The insertion piece 25 is inserted into the insertion groove 34. Through the insertion and cooperation of the extension of the inner rear plate 22, the inner lower plate 24, and the insertion piece 25 with the insertion groove 34, the connection stability between the inner layer 2 and the foam body 3 is further enhanced, the relative displacement between the inner layer 2 and the foam body 3 during transportation is reduced, and the transportation safety of fragile fresh food is ensured.

[0029] Both side walls 14 of the box body 1 are provided with waist-shaped holes 15. The waist-shaped holes 15 provide a point of leverage for the handling personnel, making it easy to carry out the handling of the packaging box by gripping the waist-shaped holes 15.

[0030] The foam body 3 has grooves 35 on both sides corresponding to the side wall 14. The inner side plate 23 has a slide rail 26 at the corresponding position of the groove 35. The inner layer 2 has a partition 4 inside. The two sides of the partition 4 are slidably connected in the corresponding groove 35 and slide rail 26. Through the sliding fit structure of the groove 35, slide rail 26 and partition 4, the partition 4 can be adjusted in the inner space of the inner layer 2. This allows for flexible division of the internal space of the foam body 3 according to the specifications, quantity or transportation requirements of fragile fresh food, thereby improving the space utilization of the packaging box and its adaptability to different items.

[0031] The top of the box body 1 is provided with a lid 5, which is a cover structure with an inner cavity at the bottom. The outline of the inner cavity of the lid 5 is adapted to the outer outline of the opening at the top of the box body 1. The lid 5 can be tightly fastened to the top of the box body 1, completely covering the opening at the top of the box body 1, providing sealed protection for the fragile fresh food inside the box body 1, reducing the risk of external dust, moisture, foreign objects and other substances entering the inside of the box body 1, while enhancing the overall stability of the packaging box structure and preventing damage to the top structure of the box body 1 or accidental spillage of the contents during transportation.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
