Description

Technical Field

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

[0002] Fruit and vegetable packaging boxes are functional packaging containers specifically designed for fruits and vegetables. They are typically made from environmentally friendly materials such as pulp, corrugated paper, biodegradable plastics, or bamboo fiber. Suitable for supermarkets, e-commerce logistics, and gift scenarios, they are lightweight, stackable, and easily recyclable, balancing product protection with the needs of sustainable development. Existing fruit and vegetable packaging boxes are usually made of single-layer paper material, which has poor strength and pressure resistance. During transportation, the fruits and vegetables inside the packaging boxes are easily damaged by pressure. In addition, the ventilation effect of the packaging boxes is not good, which cannot guarantee the normal ventilation of the fruits and vegetables. Therefore, the use effect of the packaging boxes is not good. To this end, we have improved the above-mentioned existing technology based on actual usage. Utility Model Content

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0020] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Example 1: Please see Figure 1-4 This utility model provides a technical solution: a breathable and pressure-resistant fruit and vegetable packaging box, including a packaging box body 1. The inner walls of the packaging box body 1 are provided with reinforcing frames 9. Multiple sets of horizontal reinforcing ribs 10 and vertical reinforcing ribs 11 are installed on the inner walls of the reinforcing frames 9, and the horizontal reinforcing ribs 10 and vertical reinforcing ribs 11 are connected in an alternating manner. Sliding grooves 8 are provided at the top of the inner walls on both sides of the packaging box body 1. A box cover 2 is slidably connected within adjacent sliding grooves 8, and multiple sets of ventilation holes 3 are provided on the box cover 2. Two sets of limiting devices are provided on the front face of the packaging box body 1. The limiting component of the lid 2; the main body of the packaging box 1 is made of paper material, and the reinforcing frame 9 is made of hard paper material. Through four sets of reinforcing frames 9, each set of reinforcing frames 9 has multiple sets of horizontal reinforcing ribs 10 and vertical reinforcing ribs 11 to improve the strength of the entire fruit and vegetable packaging box, improve the pressure resistance of the fruit and vegetable packaging box, and avoid damage to fruits and vegetables during transportation. Multiple sets of ventilation holes 3 on the lid 2 play a role in ventilation, ensuring normal ventilation of fruits and vegetables, improving the freshness of fruits and vegetables, and improving the use effect of fruit and vegetable packaging box; The limiting component includes a telescopic connecting rod 5 that is movably connected to the outer wall of the front side of the packaging box 1, and a rotating pressure plate 7 is installed at the other end of the telescopic connecting rod 5. The inner side of the rotating pressure plate 7 is attached to the outer wall of the box cover 2. Through the action of the telescopic connecting rod 5 on the limiting component, the rotating pressure plate 7 can be blocked at the front end of the box cover 2 or removed from its front end, making it easy to remove the box cover 2 from the adjacent slide groove 8, which facilitates the use of fruits and vegetables in the fruit and vegetable packaging box.

[0022] Preferably, the telescopic link 5 is rotatably connected to the outer wall of the packaging box 1 via a bearing, and the outer wall of the telescopic link 5 is fitted with a spring 6. The telescopic link 5, which is rotatably connected via a bearing, can be easily rotated, causing the rotating pressure plate 7 to rotate. The elasticity of the spring 6 allows the rotating pressure plate 7 to always be in contact with the front end of the box cover 2, thereby fixing the position of the box cover 2. When the rotating pressure plate 7 needs to be removed from the front end of the box cover 2, the rotating pressure plate 7 rotates to remove it from the front end of the box cover 2. At this time, the position of the box cover 2 is no longer restricted, and the box cover 2 can be removed from the adjacent slide groove 8.

[0023] Preferably, a paper frame 12 is provided in the inner cavity of the packaging box 1 and inside the four sets of reinforcing frames 9, and multiple sets of partition plates 13 are provided on the inner wall of the paper frame 12; the paper frame 12 and partition plates 13 made of cardboard can separate fruits and vegetables, and together with the multiple sets of ventilation holes 3 on the box lid 2, they can ensure normal ventilation of fruits and vegetables and improve the freshness of fruits and vegetables.

[0024] Preferably, a handle 4 is installed on the outer wall of the lid 2, and the hand-held end of the handle 4 is covered with an anti-slip rubber sleeve; the handle 4 facilitates the pulling of the lid 2 and makes it easy to remove the lid 2, and the anti-slip rubber sleeve plays an anti-slip role to prevent the hand from slipping off when holding the handle 4.

[0025] Preferably, the inner cavity bottom wall of the packaging box 1 is coated with a waterproof coating, and the paper frame 12 and the partition board 13 are both made of cardboard; the waterproof coating plays a waterproof role, improves the waterproof performance of the packaging box 1, and prevents the fruit and vegetable packaging box from being damaged after water enters.

[0026] Example 2: Reference Figure 2 The difference between this embodiment and the first embodiment is that: the rotating pressure plate 7 is provided with an anti-slip pad on the side near the box cover 2, and the anti-slip pad is connected to the rotating pressure plate 7 by adhesive; the anti-slip pad plays an anti-slip role, further improving the stability of the rotating pressure plate 7 when limiting the box cover 2, and the adhesive anti-slip pad can be easily disassembled and replaced later.

[0027] It should be noted that the electrical component of this utility model is used to organize the wire harness during operation, and will not cause the wire harness to become tangled.

[0028] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
