[0002] A paper box is a container folded from paper or processed paper, mainly used for packaging, storing, transporting or displaying items, and can be designed into various shapes and sizes according to different requirements to adapt to the size of the items to be shipped. The uses of paper boxes are very extensive and are widely used in industries such as daily commodity packaging, food packaging, pharmaceutical packaging and transportation packaging. According to the structure classification, they are divided into folding paper boxes and fixed paper boxes. In the above industries, in order to facilitate storage and processing, folding paper boxes are usually used. Moreover, in order to facilitate the opening of the paper box for use, there is a existing bottom-locking paper box, also known as a bottom-fastening paper box, which realizes the structural stability through the mutual restriction and hook of the bottom surface of the paper box, without excessive adhesives or additional fixing measures, improving the packaging efficiency. However, the inventor found during daily use and the packaging process that the bottom of the bottom-locking paper box is very prone to deformation. When the bottom is pushed or impacted by an object, the hooked position will concave into the paper box, generating gaps and even deforming, affecting the protection of the items inside the paper box packaging. Content of the Utility Model

[0006] The support assembly includes two support plates connected to the bottom-locking box body. Both support plates include a base plate portion connected to the short side at the upper end of the bottom-locking box body, and a connecting portion is provided on the end face of the base plate portion away from the bottom-locking box body, and a support portion is provided on the side of the connecting portion away from the base plate portion.

[0007] The base plate portion, the connecting portion and the support portion can all fold and rotate around the positions they are connected to, and the connecting portion and the support portion can be folded into the bottom-locking box body.

[0008] The sum of the lengths of the base plate portion and the connecting portion is greater than the height of the inner cavity of the bottom-locking box body.

[0009] In order to improve the buffering of the shorter panel on the side of the bottom-hooking box body and protect the items inside the box, two reinforcing plates are provided between the surfaces where the two long sides of the bottom-hooking box body are located. The two reinforcing plates respectively form buffer cavities with the side surfaces of the bottom-hooking box body on both sides. Ear plates are connected to both sides of the reinforcing plates, and the ear plates are fixed to the inner side surfaces of the bottom-hooking box body.

[0010] In order to prevent the reinforcing plates from compressing the internal space of the bottom-hooking box body, the two reinforcing plates are symmetrically arranged, and the length of the buffer cavity along the long side direction of the bottom-hooking box body is 1 / 20 - 1 / 15 of the long side.

[0011] In order to enable the substrate part to block the buffer cavity after folding, the length of the substrate part is the same as the length of the short side of the bottom-hooking box body.

[0012] In order to facilitate squeezing the folded connecting part and supporting part into the bottom-hooking box body, the length of the connecting part along the short side of the bottom-hooking box body is greater than the distance between the ear plates on both sides of the supporting plate.

[0013] In order to be able to assist in supporting the bottom of the bottom-hooking box body, the height of the reinforcing plate is the same as the height of the inner cavity of the bottom-hooking box body.

[0014] In order to improve the supporting strength of the supporting part on the bottom of the bottom-hooking box body, the length of the supporting part along the short side of the bottom-hooking box body is the same as that of the connecting part, and the length of the short side of the supporting part is not less than 1 / 5 of the length of the long side of the bottom-hooking box body.

[0015] In order to further improve the support for the bottom of the bottom-hooking box body and be able to divide the internal space of the bottom-hooking box body to meet different packaging requirements, vertical and opposite slots are provided on both inner side surfaces of the bottom-hooking box body, and partitions can be installed in the slots, and the partitions are in contact with the bottom of the bottom-hooking box body.

[0016] In order to facilitate the encapsulation and unsealing of the box body, two cover plates are connected to the upper ends of the two long sides of the bottom-hooking paper box, and the cover plates can be folded. Adhesive tapes are provided on any one of the cover plates, and a tear strip is provided at the middle position of the cover plate.

[0017] The beneficial effects of the present utility model are as follows: The present utility model is a paper box with a support component. Firstly, through the first bottom tongue and the second bottom tongue arranged at the bottom of the bottom-locked box body, their mutual buckling can seal the bottom of the box body, and through the two cover plates arranged at the upper end of the bottom-locked box body, the top of the box body can be sealed, realizing the function of packaging items; Secondly, through the design of two support plates, two buffer cavities are formed between the support plates and the two sides of the box body. When the side of the box body is collided or impacted, it can provide a deformation space for the side of the box body. The deformation of the side panel of the box body can offset part of the impact force, and the support plates form a secondary protection, reducing the impact on the items inside the box body; Finally, through the connection of the substrate part, the connection part and the support part at the two short sides of the bottom-locked box body, the connection part and the support part can enter the box body around the folding position, and the support part can be folded to the horizontal state around the connection position and abutted against the tongue bottom at the bottom of the bottom-locked box body. After the two cover plates at the upper end are folded, they can abut against the upper end of the connection part and the inner side of the bottom-locked box body to limit the extrusion of the connection part. Then, the connection part and the support part form a support for the bottom of the bottom-locked box body, improving the buckling strength of the bottom tongue and effectively slowing down the deformation when the bottom is impacted.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following will describe the exemplary embodiments of the present disclosure in more detail with reference to the drawings.

[0027] Embodiment

[0028] As mentioned in the background art, although the existing bottom-hooking paper box is relatively convenient to use, it has certain defects. Since the multiple bottom tongues at its bottom are mutually buckled, the stability is poor. When subjected to external force impact, it is prone to concave deformation or even damage, which is not conducive to protecting the items in the paper box. Therefore, the inventor improved on the existing bottom-hooking paper box and designed a new type of paper box with a support component. The following will be specifically described with reference to the drawings.

[0029] This embodiment provides a paper box with a support component. Refer to Figure 2 and Figure 3 , which includes a bottom-hooking box body 1. At the bottom of the bottom-hooking box body 1, there are a first bottom tongue 2 and a second bottom tongue 3, and both are arranged in two groups in a reverse corresponding manner and are mutually buckled. The structure of this bottom-hooking paper box is in the existing form. For example, the publication number is CN209956408U, which discloses a portable bottom-hooking paper box, and the way its bottom tongues are mutually buckled is as shown in the Figure 1 of its patent document. Therefore, the buckling method of the first bottom tongue 2 and the second bottom tongue 3 at the bottom of the bottom-hooking box body will not be elaborated redundantly.

[0030] In this embodiment, which is also one of the main design points of this solution, in combination with Figure 2 , the support component includes two support plates 4 connected to the bottom-hooking box body 1. The support plates 4 are integrally connected to the bottom-hooking box body 1 and can be folded. The two support plates 4 are installed at the top ends of the sides of the bottom-hooking box body 1. The two support plates 4 each include a base plate portion 41 connected to the short side at the upper end of the bottom-hooking box body 1. The base plate portion 41 can be folded around the position connected to the bottom-hooking box body 1. The base plate portion 41 is the part that is horizontal at the upper end of the bottom-hooking box body 1 after folding. Secondly, a connecting portion 42 is provided on the end face of the base plate portion 41 away from the bottom-hooking box body 1, and the connecting portion 42 can be folded around the position connected to the base plate portion 41. Along with the folding of the base plate portion 41 into the bottom-hooking box body 1, the connecting portion 42 is in a vertical state after folding. And, the sum of the lengths of the base plate portion 41 and the connecting portion 42 is greater than the height of the inner cavity of the bottom-hooking box body 1, so as to ensure that after folding, the connecting portion 42 can abut against the bottom tongue at the bottom of the bottom-hooking box body 1. A support portion 43 is provided on the side of the connecting portion 42 away from the base plate portion 41. The support portion 43 can be folded around the connection position with the connecting portion 42, so that after the connecting portion 42 is folded into the bottom-hooking box body 1 and then folded upward to a horizontal state, the bottom surface abuts against the bottom tongue at the bottom of the bottom-hooking box body 1 to form a support.

[0031] Moreover, in order to seal the upper end of the bottom-hooking box body 1, two cover plates 10 are connected to the upper ends of the two long sides of the bottom-hooking paper box, and the cover plates 10 can be folded. A pasting tape 11 is provided on any one of the cover plates 10, and a tear strip 12 is provided at the middle position of the cover plate 10. The tear strip 12 is a common prior art in the field of packaging boxes and will not be elaborated further. When sealing, the cover plate 10 without the pasting tape 11 is folded towards the side of the bottom-hooking box body 1, and it abuts above the folded support plate 4 to provide support for it, so that its support portion 43 can tightly abut against the bottom tongue. Secondly, the cover plate 10 provided with the pasting seal is folded onto the lower cover plate 10 and fixed by the pasting tape 11.

[0032] In this embodiment, a design is also made for the buffering of the side panels of the bottom-hooking box body 1, which can effectively reduce the overall deformation degree of the box body and protect the internal objects. Among them, two reinforcing plates 5 are provided between the two long-side surfaces of the bottom-hooking box body 1. Moreover, the two reinforcing plates 5 are symmetrically arranged to ensure the balance of both ends of the bottom-hooking box body 1. The two reinforcing plates 5 respectively form a buffer cavity 6 with the side surfaces of the bottom-hooking box body 1 on both sides, and the length of the buffer cavity 6 along the long side direction of the bottom-hooking box body 1 is 1 / 20 - 1 / 15 of the long side, which can prevent the reinforcing plates 5 from overly compressing the space inside the bottom-hooking box body 1. By designing the buffer cavity 6, when the side surface of the bottom-hooking box body 1 is collided or impacted, it can provide a deformation space for the side surface of the bottom-hooking box body 1. The deformation of the side panel of the bottom-hooking box body 1 can offset part of the impact force, and the support plate 4 forms a secondary protection, reducing the impact on the items inside the box body. The two sides of the reinforcing plate 5 are connected with ear plates 7. The ear plates 7 and the reinforcing plate 5 can be integrally formed, and they can be folded between them. And the ear plates 7 are fixed to the inner side surface of the bottom-hooking box body 1, specifically, adhesives or pneumatic nails can be used. Moreover, the height of the reinforcing plate 5 is the same as the inner cavity height of the bottom-hooking box body 1, so that after the cover plate 10 is covered, it can abut against the reinforcing plate 5 through the support plate 4 for auxiliary support.

[0033] Moreover, since the reinforcing plate 5 is designed at a position close to the side surface of the bottom-hooking box body 1, the design of the support plate 4 in this solution should be adapted to the reinforcing plate 5. The length of the base plate portion 41 is the same as the length of the short side of the bottom-hooking box body 1. And after the base plate portion 41 is folded towards the bottom-hooking box body 1, the edge position where the base plate portion 41 is connected to the connecting portion 42 is flush with the side surface of the reinforcing plate 5 close to the bottom-hooking box body 1, so that the base plate portion 41 can completely seal the upper end of the buffer cavity 6.

[0034] On the basis of the above structure, combined with Figure 4, after the connecting portion 42 is folded, the front and rear inner end faces of the bottom-hooking box body 1 are required to squeeze it into the bottom-hooking box body 1. Therefore, the length of the connecting portion 42 along the short side of the bottom-hooking box body 1 is greater than the distance between the two side ears 7 of the support plate 4. In this solution, the length of the connecting portion 42 along the short side of the bottom-hooking box body 1 is slightly greater than the distance between the two side ears 7 of the support plate 4, so that the connecting portion 42 can be squeezed. During folding, the substrate portion 41 can completely cover the buffer cavity 6 and fold the connecting portion 42 downward into the bottom-hooking box body 1. The end face of the connecting portion 42 fits against the reinforcing plate 5, and the side face abuts against the two longer side faces of the bottom-hooking box body 1 to provide support.

[0035] Moreover, the length of the supporting portion 43 along the short side of the bottom-hooking box body 1 is the same as that of the connecting portion 42, and the length of the short side of the supporting portion 43 is not less than 1 / 5 of the length of the long side of the bottom-hooking box body 1, so that the supporting portion 43 has a larger supporting area when supporting. The length of the supporting portion 43 is the same as the distance between the two side ears 7, that is, the length of the supporting portion 43 in this direction is also slightly greater than the distance between the two side ears 7, so that the inner end face of the bottom-hooking box body 1 squeezes the supporting portion 43 in the box body. The supporting portion 43 is folded into the bottom-hooking box body 1 together with the connecting portion 42. When the supporting portion 43 is folded upward, the connecting portion 42 is adjusted to the vertical position, and the bottom abuts against the bottom tongue. When the bottom is impacted, the connecting portion 42 provides support for the bottom tongue through the friction force with the inner side face of the box body.

[0036] Moreover, combined with Figure 2 , on both inner sides of the bottom-hooking box body 1, slots 8 are vertically and oppositely provided. The slots 8 are provided on the two long side surfaces of the bottom-hooking box body 1, located at the middle position of the bottom-hooking box body 1, and a partition 9 can be installed in the slots 8. The partition 9 abuts against the bottom of the bottom-hooking box body 1, and the upper end is flush with the upper end face of the folded substrate portion 41. Figure 2 In order to conveniently show the slot 9, the partition 9 is truncated and not fully shown. The partition 9 can be selected for use. On the one hand, it can separate the internal space of the bottom-hooking box body 1 to meet different packaging requirements. On the other hand, after the cover plate 10 is sealed, the partition 9 abuts against the cover plate 10 and the bottom tongue, further improving the support for the bottom of the bottom-hooking box body 1.
