[0001] The utility model relates to the technical field of paper boxes, in particular to a paper box with a buffer protection function. Background Art
[0002] At present, paper boxes are required for product packaging in more and more industries, such as cosmetics, fruits, furniture, etc. Paper boxes have become one of the more widespread packaging products. Due to their low cost, convenient encapsulation, cleanliness and other characteristics, they have become an important choice for product packaging and shipping. And there are many types of paper boxes on the market, which can meet the basic packaging needs to a certain extent. However, in actual use, especially during express delivery, the inventor found that many paper box packages at express stations are deformed and damaged to a certain extent, and the support and buffer effects are poor. Although buffer foam can be set inside, the buffer foam needs to be fixed with tape or other items, making the packaging require more time and having poor packaging efficiency. Content of the Utility Model
[0003] In order to solve the technical problems existing in the above background art, the utility model provides a paper box with a buffer protection function.
[0004] The technical solution of the utility model is as follows:
[0005] A paper box with a buffer protection function includes a U-shaped box body formed by folding, and the opening is upward. One end of the U-shaped box body is connected with a first cover plate, and the other end is connected with a second cover plate. Both the first cover plate and the second cover plate can be folded towards the opening side of the U-shaped box body, and after folding, the first cover plate is located below the second cover plate;
[0006] Two baffle parts are installed at both ends inside the U-shaped box body, and the upper ends of the baffle parts are flush with the upper end of the U-shaped box body. The baffle parts are bent towards the inside of the U-shaped box body, and their outer sides form a buffer cavity with the inner side of the U-shaped box body;
[0007] A cavity plate is connected to the side of the first cover plate close to the opening of the U-shaped box body. Two limiting plates are installed on the inner side of the baffle part, and buffer foam is placed both inside the cavity plate and between the limiting plates.
[0008] The specific design of the baffle part is that the baffle part includes a bottom plate connected to the bottom of the U-shaped box body. A baffle main body is installed on the bottom plate, and the outer sides of the bottom plate and the baffle main body are located inside the U-shaped box body.
[0009] In order to improve the stability of the baffle part, side plates that can be folded are integrally formed at the tops of both ends of the baffle main body, and the side plates are connected with connecting plates bent at 180° thereto, and the connecting plates are connected with the inner side of the U-shaped box body.
[0010] To improve the support performance of the connecting plate, the end of the connecting plate away from the side plate extending in the direction away from the side plate is flush with the side of the U-shaped box body.
[0011] To facilitate placing buffer foam in the cavity plate, a strip-shaped groove communicating with its cavity is opened on the upper end surface of the cavity plate.
[0012] To improve the buffering effect of the buffer foam in the cavity plate, a contact groove communicating with its cavity is opened on the side of the cavity plate close to the opening of the U-shaped box body, and the length of the contact groove is less than the length of the strip-shaped groove.
[0013] To be able to cover the first cover plate on the U-shaped box body, the cavity plate is located in the middle of the first cover plate, and its length is not greater than the distance between the two baffle bodies, and its width is not greater than the distance between the two side plates.
[0014] The distance between the two limiting plates on the same side is not less than the width of the cavity plate.

[0025] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.
[0026] Embodiment
[0027] As mentioned in the background art, the existing packaging paper boxes can achieve simple packaging functions. However, the inventor found during use and in daily life that the paper boxes are prone to deformation and even damage during transportation and stacking. Especially, the side deformation of the paper boxes is relatively large, which is likely to damage the items inside the paper boxes. Moreover, the buffer foam 8 filled in the paper boxes often gets displaced and needs to be fixed separately, which wastes a lot of time on the one hand and is rather laborious to fix the foam inside the box on the other hand. Therefore, the inventor improved on the existing paper boxes and designed a paper box with a buffer protection function, which will be specifically described below with reference to the drawings.
[0028] This embodiment provides a paper box with a buffer protection function. Refer to Figure 1, including a folded U-shaped box body 1 with an upward opening. The U-shaped box body 1 is a cuboid as a whole and is integrally formed. A creasing machine is used to press out the folding lines. In order to seal the upper end of the U-shaped box body 1, a first cover plate 2 is connected to one end of the U-shaped box body 1, and a second cover plate 3 is connected to the other end. The connection positions of the first cover plate 2 and the second cover plate 3 with the U-shaped box body 1 are all pressed out by a creasing machine and are integrally formed. Both the first cover plate 2 and the second cover plate 3 can be folded towards the opening side of the U-shaped box body 1, and after folding, the first cover plate 2 is located below the second cover plate 3. Moreover, the two are fixed in an adhesive form. Specifically, a sticky tape 13 is provided on the second cover plate 3, that is, it is arranged on the end face close to the first cover plate 2 after folding and is located at the end position away from the U-shaped box body 1. When fixing, tear off the protective film of the sticky tape 13 and paste the second cover plate 3 onto the upper end face of the first cover plate 2. And in order to facilitate quick disassembly, an easy tear strip 14 is provided at the middle position of the second cover plate 3. The easy tear strip 14 is a mature prior art in the field of packaging boxes and will not be elaborated further.
[0029] As one of the main design points of this solution, two baffle parts 4 are installed at both ends inside the U-shaped box body 1, and the upper ends of the baffle parts 4 are flush with the upper end of the U-shaped box body 1. The baffle parts 4 are bent towards the inside of the U-shaped box body 1, that is, the baffle parts 4 are used to block the concave of the plate of the U-shaped box body 1 inside the U-shaped box body 1, so that the outer side surface forms a buffer cavity 5 with the inner side surface of the U-shaped box body 1. Specifically, the baffle part 4 includes a bottom plate 41 connected to the bottom of the U-shaped box body 1. The bottom plate 41 and the bottom of the U-shaped box body 1 can be connected by bonding or pressing. A baffle main body 42 is installed on the bottom plate 41. The upper end surface of the baffle main body 42 is flush with the U-shaped box body 1. The baffle main body 42 is the plate used to block the side opening of the U-shaped body. And the outer side surfaces of the bottom plate 41 and the baffle main body 42 are located inside the U-shaped box body 1, so that a buffer cavity 5 is formed outside the baffle main body 42, the bottom plate 41 and the inner side of the U-shaped box body 1. When the side of the paper box is impacted by other items, since the baffle main body 42 is located inside the U-shaped box body 1, the edge of the U-shaped box body 1 bears the impact first. And due to the existence of the buffer cavity 5, the U-shaped box body 1 may block other items outside the buffer cavity 5 or make part of the position of other items enter the buffer cavity 5, avoiding or reducing the impact of other items on the baffle main body 42.
[0030] Based on the above structure, at the top of both ends of the baffle main body 42, side plates 43 that can be folded are integrally formed. The side plates 43 are connected to a connecting plate 44 that is bent at 180° therewith. The baffle main body 42, the side plates 43, and the connecting plate 44 are all integrally formed. After being pressed by a wire pressing machine and folded into the shape shown in the figure, the connecting plate 44 can be fixed to the inner side surface of the U-shaped box body 1 by bonding or using air nails. Moreover, the end of the connecting plate 44 extending away from the side plate 43 is flush with the side surface of the U-shaped box body 1, that is, the outer side surface of the connecting plate 44 is flush with the U-shaped box body 1. By setting the connecting plate 44 to be flush with the U-shaped box body 1, the supporting force of the side surface of the U-shaped box body 1 can be improved, and further play a role in buffering and protecting the baffle main body 42.
[0031] As one of the other main design points of this solution, combined with Figure 2 , on the side of the first cover plate 2 close to the opening of the U-shaped box body 1, a cavity plate 6 is connected. A buffer foam 8 is placed in the cavity plate 6. And for the convenience of placement, a strip-shaped groove 9 communicating with its cavity is opened on the upper end surface of the cavity plate 6. The buffer foam 8 is placed into the cavity of the cavity plate 6 in the strip-shaped groove 9. The cavity plate 6 can limit and fix it to ensure its stability. And in order to further exert the buffering effect of the buffer foam 8, a contact groove 10 communicating with its cavity is opened on the side of the cavity plate 6 close to the opening of the U-shaped box body 1, so that the buffer foam 8 can be exposed into the U-shaped box body 1 at the contact groove 10, enabling the buffer foam 8 to directly exert a buffering effect on the upper end of the items in the paper box. And the length of the contact groove 10 is less than the length of the strip-shaped groove 9, which can effectively limit the buffer foam 8 and prevent it from falling out of the cavity plate 6.
[0032] Based on the above structure, combined with Figure 3 , in the figure, the dotted line part is the projection of the cavity plate 6 towards the first cover plate 2 when the first cover plate 2 covers the U-shaped box body 1. Two limiting plates 7 are installed on the inner side surface of the baffle part 4. Specifically, the limiting plates 7 are installed on the inner side surface of the baffle main body 42, and buffer foams 8 are placed between the limiting plates 7, which can effectively buffer and protect the sides of the items. Moreover, through the design of the two limiting plates 7, the fixing and limiting of the buffer foams 8 can be realized, reducing the degree of their dislocation. And the cavity plate 6 and the limiting plates 7 can be fixed to the corresponding positions by bonding, or the whole can be folded, which is also convenient for the storage of the paper box.
[0033] It should be noted that the cavity plate 6 is located in the middle of the first cover plate 2, and its length is not greater than the distance between the two baffle bodies 42, and its width is not greater than the distance between the two side plates 43. When the first cover plate 2 is covered on the U-shaped box body 1, the cavity plate 6 can enter the space between the U-shaped box body 1 and the two baffle bodies 42 on both sides as a whole. The distance between the two limiting plates 7 on the same side is not less than the width of the cavity plate 6, so that the cavity plate 6 is located between the limiting plates 7 as a whole. In this way, the requirement for the thickness of the cavity plate 6 is relatively low. On the premise of ensuring that items can be loaded into the paper box and covered, the thickness of the cavity plate 6 can be thicker, making the buffer foam 8 thicker and improving the buffer effect.
[0034] Moreover, slots 11 are vertically and oppositely formed on both inner sides of the U-shaped box body 1, and a partition 12 can be installed in the slots 11. By designing the slots 11 to install the partition 12, the space inside the U-shaped box body 1 can be separated, increasing the usage function of the paper box. And when the first cover plate 2 is covered on the box body, the partition 12 can support the cavity plate 6, improving the overall stability of the paper box.
