Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging box technology, specifically a packaging box with a cushioning structure. Background Technology
[0002] In the modern logistics and commodity transportation industry, packaging serves as a "protective barrier" for goods, and its cushioning performance directly determines the integrity of products during transportation, storage, and handling. With the booming development of e-commerce, the number of commodity circulation links has increased, transportation distances have become longer, and handling frequency has increased, causing products to face various external force threats such as collisions, squeezing, and vibrations during transportation. This places higher demands on the cushioning performance of packaging boxes. Against this backdrop, the development of a packaging box with an efficient cushioning structure has become an urgent need for the industry.
[0003] However, the existing plastic packaging box structure still has some problems in use:
[0004] First, traditional plastic packaging boxes have insufficient cushioning performance. Many plastic packaging boxes use simple single-layer honeycomb or grid-like cushioning structures. When subjected to a large impact, these structures are prone to one-time crushing and cannot effectively disperse and absorb energy.
[0005] Secondly, the space utilization rate is low, and the internal space of the plastic box cannot be flexibly divided. Moreover, the solid space makes it easy for items to move around a lot inside the box, thus reducing the practicality of the box. Utility Model Content
[0006] In order to solve the problems of insufficient cushioning performance and low space utilization of existing plastic packaging boxes, the purpose of this utility model is to provide a packaging box with a cushioning structure.
[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a packaging box with a cushioning structure, including a box body, a partition component inside the box body, a cushioning component inside the box body, the cushioning component including a mounting groove, the mounting groove being opened inside the box body, a foam pad layer being fixedly installed on the inner wall of the mounting groove, an air bubble pad layer being fixedly sleeved on the outer surface of the foam pad layer, a honeycomb pad layer being fixedly sleeved on the outer surface of the air bubble pad layer, and a bio-based pad layer being fixedly sleeved on the outer surface of the honeycomb pad layer.
[0008] Preferably, the separating component includes multiple slots, which are fixedly installed on the inner wall of the box body. A separating plate is movably engaged with the inner wall of the corresponding slot. A positioning sleeve is fixedly connected to the upper surface of the slot. A limiting plate is movably engaged with the inner wall of the positioning sleeve. A bolt is threadedly connected between the positioning sleeve and the limiting plate.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] 1. This application uses a buffer component and a buffer pad layer in combination to achieve sequential deformation of the multi-layer structure when subjected to external impact, thereby absorbing energy in stages, extending the buffering time, and improving the buffering effect.
[0011] 2. This application, through the partition component and the setting of adjustable partitions, can flexibly and reasonably divide the internal space of the packaging box according to the size and shape of different items. This design effectively reduces the space for items to move within the box and improves the practicality of the packaging box. Attached Figure Description

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0019] Example: Figure 1-4 As shown, this utility model provides a packaging box with a cushioning structure, including a box body 1. Protective pads 4 are symmetrically fixedly fitted onto the lower surface of the box body 1. The protective pads 4 are symmetrically arranged on the lower surface of the box body 1, and can directly contact the ground when the packaging box is placed or dropped. They absorb the impact force through their own elastic deformation, reduce the impact on the bottom of the box body 1, and effectively protect the items inside the box. A box lid 5 is movably snapped onto the upper surface of the box body 1. The box lid 5 is movably snapped onto the box body 1, which facilitates opening and closing the packaging box and makes it easy to store and retrieve the items. The box lid 5 is a non-slip cover. The design of the non-slip cover increases the friction of the surface of the box lid 5, prevents the box lid 5 from slipping off the box body 1, and improves the stability during transportation.
[0020] The box body 1 is equipped with a partition component 3 inside, which can reasonably divide the internal space of the box body 1, fix the position of the items, and prevent the items from colliding with each other or moving significantly during transportation, thereby comprehensively improving the protective performance and practicality of the packaging box. The box body 1 is also equipped with a buffer component 2 inside, which can effectively absorb external impact and reduce the vibration of the items.
[0021] The buffer assembly 2 includes a mounting groove 25, which is located inside the box body 1. The mounting groove 25 provides a mounting base for other components of the buffer assembly 2. A foam pad 24 is fixedly installed on the inner wall of the mounting groove 25. The foam pad 24 is made of EPE pearl cotton material and has good elasticity and conformability. After being fixedly installed on the inner wall of the mounting groove 25, it effectively buffers high-frequency small-amplitude vibrations. An air bubble pad 23 is fixedly sleeved on the outer surface of the foam pad 24. The air bubble pad 23 is specifically composed of two layers of low-density polyethylene PE film material. The air bubble pad 23 is sleeved on the outer surface of the foam pad 24. The air bubbles inside can be compressed and deformed when subjected to external impact, absorbing medium and low frequency large impact energy. Together with the foam pad 24, it forms a multi-layer buffer, further enhancing the protection of the items and effectively resisting collisions and drops during transportation.
[0022] A honeycomb-shaped pad 22 is fixedly sleeved on the outer surface of the bubble pad 23. The honeycomb-shaped pad 22 is specifically composed of polyethylene (PE) plastic sheet material. The honeycomb-shaped pad 22 has high strength and good compressive strength. It is fixed on the outer surface of the bubble pad 23 and can serve as a support frame for the entire buffer assembly 2. When subjected to external pressure, the honeycomb structure can evenly distribute the pressure. A bio-based cushioning layer 21 is fixedly sleeved on the outer surface of the honeycomb cushioning layer 22. The bio-based cushioning layer 21 is made of starch-based materials, mainly corn starch and cassava starch, with added biodegradable additives. The bio-based cushioning layer 21 is sleeved on the outer surface of the honeycomb cushioning layer 22, which, while ensuring cushioning performance, gives the packaging box environmental protection properties. The cross-sectional shape of the foam cushioning layer 24, bubble cushioning layer 23, honeycomb cushioning layer 22 and bio-based cushioning layer 21 is all U-shaped. The U-shaped cross-sectional shape allows each cushioning layer to form a ring around the item inside the box, achieving all-round cushioning protection for the item and avoiding any blind spots. No matter which direction the item is impacted from, energy can be absorbed through the sequential deformation of the multiple layers of cushioning, maximizing the cushioning effect.
[0023] The partition component 3 includes multiple slots 37, which are fixedly installed on the inner wall of the box body 1. A partition plate 31 is movably engaged with the inner wall of the corresponding slot 37. The multiple slots 37 provide installation positions for the partition plate 31. By combining different slots 37, the partitioning method can be flexibly adjusted according to the size and shape of the items. The partition plate 31 is made of plastic. The plastic partition plate 31 has a certain strength and toughness, which can stably partition the space. A positioning sleeve 32 is fixedly connected to the upper surface of the slot 37. A limiting plate 36 is movably engaged with the inner wall of the positioning sleeve 32. The cooperation between the positioning sleeve 32 and the limiting plate 36 can limit and fix the partition plate 31 in the vertical direction.
[0024] The upper surface of the limiting plate 36 is symmetrically fixedly connected with guide strips 35. The inner wall of the positioning sleeve 32 is symmetrically provided with guide grooves 34 for use with the guide strips 35. The guide strips 35 and guide grooves 34 are movably engaged. The engagement of the guide strips 35 and guide grooves 34 provides precise guidance for the installation of the limiting plate 36, allowing the limiting plate 36 to be quickly and accurately engaged in the positioning sleeve 32. The cross-sectional shape of the limiting plate 36 is inverted L-shaped. The limiting plate 36 is movably engaged on the upper surface of the slot 37. The inverted L-shaped limiting plate 36 can press the partition plate 31 into the slot 37 from above, providing a reliable limiting effect through its own structural characteristics, preventing the partition plate 31 from coming off upward. The positioning sleeve 32 and the limiting plate 36 are threadedly connected with bolts 33. The setting of bolts 33 further strengthens the connection and tightness between the positioning sleeve 32 and the limiting plate 36, realizing the flexible and stable function of the partition component 3.
[0025] Working principle: First, the box 1 serves as the main supporting structure, providing space for the various internal components and items.
[0026] When the packaging box is subjected to an external impact, the outermost bio-based cushion layer 21 of the cushioning component 2 comes into contact with the external force first, and its own cushioning performance initially attenuates the impact force. Subsequently, the impact force is transmitted to the honeycomb cushion layer 22, and the energy is dissipated through the deformation of the honeycomb structure.
[0027] Next, the air compression of the bubble pad 23 further disperses the impact force, and finally the foam pad 24 absorbs the remaining energy through elastic deformation. The four pads buffer the impact force step by step from the outside to the inside, protecting the internal contents.
[0028] For the separate storage of items, the partition component 3 plays an important role. Multiple slots 37 are fixedly installed on the inner wall of the box body 1. According to the size and quantity of items, the partition plate 31 can be movably engaged with the inner wall of the corresponding slot 37, thereby dividing the interior of the box body 1 into different spaces.
[0029] Then, the limiting plate 36 is inserted into the positioning sleeve 32. Utilizing the inverted L-shaped structure of the limiting plate 36, it is movably engaged with the upper surface of the slot 37, thus playing a preliminary limiting role.
[0030] Meanwhile, the guide strips 35 symmetrically arranged on the upper surface of the limiting plate 36 are engaged with the guide grooves 34 symmetrically opened on the inner wall of the positioning sleeve 32 to ensure that the insertion direction of the limiting plate 36 is accurate and to prevent deviation.
[0031] Finally, by tightening the bolts 33, the limiting plate 36 and the positioning sleeve 32 are firmly connected, thereby stably fixing the partition plate 31.
[0032] In addition, the protective pads 4 that are symmetrically fixed to the lower surface of the box 1 can provide cushioning and anti-slip function when the packaging box is placed on a flat surface such as the ground, reducing wear on the bottom of the box 1 and preventing the packaging box from sliding.
[0033] The non-slip lid 5, which is movably latched on the upper surface of the box body 1, not only prevents dust from entering the inside of the box body 1 and protects the cleanliness of the items, but also has a non-slip texture on the surface of the lid 5 during handling and storage. The non-slip design makes it easy for users to open and close the lid 5, while preventing the lid 5 from accidentally slipping off.
[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
