Description

Technical Field

[0001] This utility model belongs to the field of packaging technology, and in particular relates to a packaging box with a surface printing layer that prevents cracking. Background Technology

[0002] In the field of packaging technology, packaging boxes are widely used for protecting, storing, and displaying various items. However, existing packaging boxes have some shortcomings in their use:

[0003] 1. Currently, some existing packaging boxes have cracking issues in the printed layer. During use, due to various external forces, such as friction and squeezing, the printed layer is prone to cracking and peeling, which not only affects the appearance of the packaging box but may also damage the items inside. At the same time, the partition design of some packaging boxes is not flexible enough and cannot be adjusted as needed, resulting in the items not being effectively separated and protected inside the packaging box.

[0004] Therefore, we propose a surface-printed anti-cracking packaging box. Utility Model Content

[0005] The purpose of this utility model is to solve the problem of cracking in the printed layer of some packaging boxes in the prior art. During use, due to various external forces, such as friction and squeezing, the printed layer is prone to cracking and peeling, which not only affects the appearance of the packaging box, but may also damage the items inside the packaging box. At the same time, the partition design of some packaging boxes is not flexible enough and cannot adjust the partition space as needed, resulting in the items not being effectively separated and protected inside the packaging box. Therefore, a packaging box with an anti-cracking surface printed layer is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A crack-resistant packaging box with a surface-printed layer, comprising:

[0008] The box body has a lid integrally formed at the rear end of the upper part of the box body, side plates integrally formed on both sides of the lid, a first limiting plate integrally formed at the front end of the lid, and second limiting plates integrally formed on both sides of the first limiting plate, for forming the entire packaging box. The box body has multiple vertical partitions inside, and a horizontal partition is provided in the middle of the vertical partitions for separating the box body.

[0009] The protective components include a matte PP film disposed on the outer wall of the box body and the lid, for protecting the outer wall of the box body and the lid.

[0010] In one possible design, multiple U-shaped limiting blocks are fixedly connected to the front and rear ends of the inner wall of the box. The vertical partition is slidably connected to the U-shaped limiting blocks for limiting the installation of the vertical partition. The horizontal partition is snapped into the middle of the vertical partition. L-shaped placement plates are fixedly connected to both sides of the inner top surface of the box cover. The horizontal partition is snapped into the inside of the two L-shaped placement plates for storing the horizontal partition.

[0011] In one possible design, a crease is provided between the lid and the body, a crease is provided between the side panel and the lid, a crease is provided between the first limiting plate and the lid, a crease is provided between the second limiting plate and the first limiting plate, and honeycomb cardboard is provided inside both the lid and the body.

[0012] In one possible design, the outer walls of both the box body and the lid are coated with a printed coating, and a matte PP film is adhered to the outer wall of the printed coating to protect it. PE coated paper is adhered to the inner wall of the box body and the lower surface of the lid to prevent the contents of the box from rubbing against the box body and lid.

[0013] In one possible design, slots are provided on both sides of the box body, and the side plates engage with the slots to limit the position of the box lid. The lower parts of the front and rear ends of the side plates are rounded to facilitate the installation of the side plates inside the slots. The inner wall of the rear end of the first limiting plate and the outer wall of the front end of the box body are fixedly connected with first magnetic blocks. The two first magnetic blocks attract each other with opposite polarities. The outer walls of the two second limiting plates near the box lid and the outer walls of the front and rear ends of the box body are fixedly connected with second magnetic blocks. The multiple second magnetic blocks attract each other with opposite polarities for the installation of the box lid.

[0014] In one possible design, the inner bottom surface of the box is fixedly connected to multiple elastic support blocks, and the upper end of the elastic support blocks is fixedly connected to a base plate for storing items.

[0015] In one possible design, both sides of the rear outer wall of the box are fixedly connected to a limiting frame, and a carrying strap is slidably connected inside the limiting frame.

[0016] In this application, during use, the packaging box primarily consists of a box body and a lid. The box body contains multiple vertical and horizontal partitions. The vertical partitions are slidably connected to U-shaped retaining blocks on the inner wall of the box, allowing for flexible installation and removal. Simultaneously, the horizontal partitions are engaged with the middle of the vertical partitions, further refining the internal space of the box. This allows users to freely adjust the number and position of the partitions according to the size and shape of the actual items, achieving optimal protection. The outer walls of the box body and lid are coated with a printed coating and bonded with a matte PP film. The matte PP film, as a high-performance protective film, effectively prevents the printed coating from cracking or peeling due to external forces, thus maintaining the packaging box's aesthetics and extending its lifespan. Meanwhile, the inner walls of the box body and the lid... The lower surface of the box is bonded with PE coated paper, which has excellent lubricity and wear resistance, preventing the contents from directly rubbing against the box and lid, thus further protecting the items and the packaging. The lid engages with the side plates and the slots on both sides of the box, achieving initial positioning. The placement of the first and second positioning plates, along with their attraction to the corresponding magnetic blocks on the box, further ensures the lid's secure installation, facilitating easy opening and closing. Positioning frames are located on both sides of the rear outer wall of the box, with internal sliding straps for easy carrying. Furthermore, multiple elastic support blocks are fixed to the inner bottom of the box, supporting the bottom plate and cushioning and protecting items stored on it from damage due to external impacts.

[0017] In this utility model, the surface printed layer anti-cracking packaging box uses matte PP film to protect the printed coating, which effectively solves the problem that the printed layer of existing packaging boxes is prone to cracking and peeling, so that the packaging box can maintain a good appearance and integrity during use. The flexible setting of vertical and horizontal partitions allows users to freely adjust the partition space according to actual needs, which is suitable for packaging items of different sizes and shapes.

[0018] In this utility model, the surface-printed anti-cracking packaging box, through the magnetic lid installation method and the sliding handle design, makes it easier for users to open and close the packaging box and carry items. At the same time, the elastic support block provides additional cushioning protection for the items stored in the packaging box. Attached Figure Description
