After more than 20 years of development, the Chinese exquisite packaging box market has emerged a variety of classic structures such as "heaven and earth box", "book-shaped box", "drawer box", and various types of products derived therefrom. These traditional packaging boxes meet some of the market's needs to some extent, but as consumers' requirements for product packaging in terms of aesthetics, functionality, and cost-effectiveness, etc. are increasingly improving, the traditional packaging structure gradually exposes some limitations.

[0003] In terms of refinement, although existing packaging boxes are constantly being updated, it is still difficult to meet the pursuit of extreme aesthetics of high-end products. For example, the material quality of some traditional packaging boxes is not good enough to highlight the high-end quality of the product; in terms of design, there is a lack of unique and novel opening method, which cannot bring consumers a novel unboxing experience.

[0004] From the perspective of production cost, some complex packaging boxes require a lot of manpower, material resources and time cost in the production process. Taking larger packaging boxes as an example, the traditional production process not only has high technical difficulty, but also has low material utilization rate, resulting in high production cost. This makes many enterprises limited by cost when choosing packaging, and unable to provide ideal packaging for products.

[0005] In terms of application range, the existing packaging structure has certain limitations. For example, some packaging structures are only suitable for specific types or sizes of products, and cannot flexibly adapt to the packaging needs of different industries and different specifications of products. There was a product packaging box opened by three-edge cutaway cover, which had a certain degree of innovation, but due to the technical problems in the production process, the material used was relatively high-end, resulting in high production cost, especially for larger packaging boxes, the cost problem was more prominent. Therefore, this type of packaging box only has local application in small packaging boxes such as cigarette packs, and is difficult to be widely promoted in the jewelry, tea, electrical appliances, hardware, plastic, etc. industries.

The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0031] A product packaging box opened by a three-edge cutout cover is described below according to an embodiment of the present application.

[0032] As shown in the drawings, the product packaging box opened by the three-edge cutout cover according to an embodiment of the present application is manufactured and used according to the following flow: Figures 1-8

[0033] 1. Component preparation:

[0034] The materials of the inner box lower bottom 1 and the inner box upper cover 2 are determined according to product requirements. If 600-1800 gram card paper is selected, multiple layers of pasting are required to achieve the required thickness and strength, and then a V-shaped groove is opened at the edge thereof; if plastic injection molding parts or wood boards are used, they are processed according to the corresponding process.

[0035] Card paper, paperboard, wood board or medium fiber board with certain hardness are selected to make the box inner surrounding edge strip 3, and the surface is pasted with color paper or colored velvet matching the outer shape of the box.

[0036] The material of the inner box filling module 4 is selected according to the size of the product packaging box. When the size is below 150*150*30MM, injection molding parts are used; when the size is above 150*150*30MM, 3MM thick wood boards or medium fiber boards are used (this is an empirical value considering production cost as a priority, and this size can be adjusted or changed according to specific circumstances).

[0037] Fine paper that can be color printed is selected as the outer pasting surface paper 6, and a layer of special adhesive is evenly applied to the back thereof.

[0038] Beef tallow paper, sulfuric acid paper, copper plate paper, writing paper or card paper are prepared to make the box inner product instruction decoration piece 5. If the product needs to be shockproof and impactproof, sponge, pearl wool or EVA are prepared as the protection assembly 7.

[0039] 2. Assembly process:

[0040] ​Inner box assembly preliminary construction: take the inner box bottom 1 and place it steadily on the workbench. The inner box bottom 1 is the basic bearing part of the entire inner box, providing stable support for subsequent assembly. Install the inner box around the edge strip 3 around the inner box filling module 4, ensure that the edge strip tightly surrounds the filling module, and leave a gap of about 0.2mm between the two to easily remove the filling module 4 later. The inner box around the edge strip 3 is made of cardboard, paperboard, wood or medium fiber board with a certain hardness, and the surface is pasted with color paper or colored flannel that matches the shape of the box. Not only can it reinforce the inner box, but also can improve the overall appearance. In addition, the inner box around the edge strip 3 will have a joint after being installed in the bottom 1, which can be designed at the corner of the box or the middle part of the upper and lower bottom connection according to customer requirements. The inner box filling module 4 is mainly used to strengthen the support strength of the color box, providing strong pressure strength for the subsequent processing equipment to flatten and de-bubble the packaging box. Its material is determined according to the size of the packaging box. When the size is below 150*150*30mm, it is an injection molding part, and when the size is larger, it uses 3mm thick wood or medium fiber board.

[0041] Complete inner box assembly: buckle the inner box upper cover 2 with the inner box bottom 1 equipped with the inner box around the edge strip 3 and the inner box filling module 4. During the buckling process, pay attention to aligning the edges to make the inner box upper cover 2 tightly combined with the inner box bottom 1, thereby forming a complete inner box assembly. At this time, the inner box upper cover 2 and the inner box bottom 1 will form a gap of 0.3-0.5mm in width at the buckling part, which plays a key role in the subsequent three-edge cutting operation to open the packaging box.

[0042] Paste the outer pasting paper: select the prepared outer pasting paper 6, which is a fine paper that can be color printed, and the back has been evenly coated with a layer of special adhesive. Carefully cover the outer pasting paper 6 on the outer surface of the inner box assembly, starting from one edge and gradually smoothing in other directions to ensure that the outer pasting paper 6 is tightly pasted on the outer surface of the inner box assembly without wrinkles and bubbles, making the entire packaging box more delicate. The pasted box product is first neatly stacked on the transfer card, and then the semi-finished product without cutting is pushed into the drying room for more than 12 hours of drying process after stacking to the appropriate height.

[0043] 3. Subsequent processing and use:

[0044] Three-edge cutting and removing filling module: pull out the qualified product after drying, use special cutting equipment to cut the hinge edge and two side edges of the box, and remove the inner box filling module.

[0045] Install inner auxiliary parts (as needed): according to the protection requirements of the packaging product, install related inner auxiliary parts such as butter paper, scratch-resistant cloth or shock-absorbing cushion sponge, EVA and other materials.

[0046] Product delivery: if the customer fills the product by himself, the matched assembled empty box is placed in the specially customized outer box and then sent to the customer. The box inner product instruction decoration piece 5 is pasted on the appropriate position inside the inner box assembly. If the product has the need of shockproof and anti-collision, the customer can place the protection assembly 7 in the position contacting with the product inside the inner box assembly.

[0047] 4. Use process:

[0048] The end customer gets the packaging box with the product assembled, only needs to tear the sealing anti-fake label pasted by the product manufacturer when assembling the product, and opens the upper cover upward to open the packaging box and take the product. After using the product, if it is needed to store the product again or collect the packaging box, firstly, the product is placed back to the inner box lower bottom 1 to ensure that the product is placed stably. Then, the protection assembly 7 is placed around the product again to tightly contact with the product to provide protection for the product. Then, the box inner product instruction decoration piece 5 is arranged well and placed back to the original position. Finally, the inner box upper cover 2 and the inner box lower bottom 1 are buckled again to align the edges of the two, and are pressed gently to ensure that the buckling is tight. At this time, the joint between the inner box upper cover 2 and the inner box lower bottom 1 forms the gap with the width of 0.3-0.5MM again, the closing operation of the packaging box is completed, and the next use is waited.

[0049] In an embodiment of the present application, as shown in Figures 1-8 In the actual manufacturing and assembling process of the product packaging box, the cooperation of multiple parts is involved. The following is the detailed working process:

[0050] 1. Preliminary construction of the inner box assembly: firstly, the inner box lower bottom 1 is taken, which is the basic bearing part of the whole inner box. The inner box filling module 4 is stably placed inside the inner box lower bottom 1. The main function of the inner box filling module 4 is to strengthen the support strength of the color box. According to the size of the packaging box, the material is different. When the size is below 150*150*30MM, it is an injection molding part. When the size is larger, it is a 3MM thick wood board or medium fiber plate.

[0051] 2. Installation of the box inner surrounding strip: the box inner surrounding strip 3 is installed around the inner box filling module 4 which has been placed, to ensure that the box inner surrounding strip 3 tightly surrounds the inner box filling module 4. The material of the box inner surrounding strip 3 is a certain hardness of cardboard, paperboard, wood board or medium fiber plate, and the surface is pasted with color paper or colored velvet which matches the whole box shape. It not only can strengthen the inner box, but also can improve the overall appearance.

[0052] 3. Assemble the inner box assembly: the inner box upper cover 2 is buckled with the inner box lower bottom 1 which is equipped with the inner box surrounding edge strip 3 and the inner box filling module 4. During the buckling process, attention should be paid to aligning the edges, so that the inner box upper cover 2 is tightly combined with the inner box lower bottom 1, thereby forming a complete inner box assembly. At this time, the inner box upper cover 2 and the inner box lower bottom 1 buckled part will form a gap with a width of 0.3-0.5MM, which plays a key role in the subsequent three-edge cutting operation to open the packaging box.

[0053] 4. Paste the outer paste paper: select the prepared outer paste paper 6, which is a fine paper that can be color printed, and the back of which has been evenly coated with a special adhesive. Carefully cover the outer paste paper 6 on the outer surface of the inner box assembly, starting from one edge and gradually smoothing it in other directions, to ensure that the outer paste paper 6 is tightly pasted on the outer surface of the inner box assembly without wrinkles and bubbles, making the entire packaging box more delicate in appearance.

[0054] 5. Place the inner box product instruction decoration and protection assembly (as needed): find a suitable position in the inner box assembly and paste the inner box product instruction decoration 5, which can be made of butter paper, sulfuric acid paper, copper plate paper, writing paper or card paper, providing consumers with product-related information. If the product has the need for shock and impact protection during transportation or storage, according to the shape and vulnerable parts of the product, place the protection assembly 7, i.e. sponge, pearl wool or EVA, in the position contacting the product inside the inner box assembly to provide protection for the product. Through the above steps, a complete three-edge cutting opening product packaging box is assembled and ready for use.

[0055] In an embodiment of the present application, as shown in Figures 1-8 the gap formed after the inner box upper cover 2 and the inner box lower bottom 1 are buckled and the three-edge cutting operation are key links in the process of making and opening the three-edge cutting opening product packaging box, and the specific work flow is as follows:

[0056] 1. Assemble the inner box assembly to form a gap: after the installation of the inner box lower bottom 1, the inner box filling module 4 and the inner box surrounding edge strip 3 are completed, the inner box upper cover 2 is buckled with the inner box lower bottom 1. When buckling, the edges of the two should be precisely aligned, and they should be tightly combined by gently pressing. At this time, the joint between the inner box upper cover 2 and the inner box lower bottom 1 will naturally form a gap with a width of 0.3-0.5MM. This gap is carefully designed, which not only provides precise position guidance for the subsequent three-edge cutting operation, but also ensures that the blade can smoothly cut in while not affecting the overall structural stability of the inner box assembly.

[0057] 2、Three-edge cutting operation: Prepare a sharp blade with a suitable width of the blade edge, the width of the blade should match the gap width to ensure the accuracy and aesthetics of the cut. When operating, align the blade edge with the gap between the inner box upper cover 2 and the inner box bottom 1, and start from the starting position of one side. Slowly and smoothly push the blade along the gap. During the cutting process, keep the blade perpendicular to the gap plane to avoid tilting or shaking, and ensure the straightness of the cut. Follow the same method to complete the cutting operation of the three edges. The order of the three-edge cutting is not strictly regulated, but it is generally recommended to start from the adjacent two edges and finally complete the third edge cutting, which can better control the cutting process and reduce damage to other parts of the packaging box.

[0058] 3、Forming a cover opening structure and opening: After completing the three-edge cutting, the connection between the inner box upper cover 2 and the inner box bottom 1 is cut off on three edges, leaving only one edge as the connection axis. At this time, by gently lifting the inner box upper cover 2, the packaging box can be easily opened, forming a unique cover opening structure. During the opening process, pay attention to the moderate force to avoid completely separating the inner box upper cover 2 from the inner box bottom 1 or damaging other parts of the packaging box. The opened cover opening structure facilitates the user to take out the product in the box, and at the same time, this novel opening method can also bring a unique user experience.

[0059] In an embodiment of the present application, as shown in Figures 1-8 The size range of the product packaging box can be customized according to customer requirements, and the minimum size is 20*20*10MM.

[0060] Specifically, in actual execution process, assuming that a small jewelry product needs to be packaged, the product packaging box with three-edge cutting and cover opening is used, and the specific use process is as follows:

[0061] 1、Opening the packaging box: Take the product packaging box that has been made, at this time the outer cover paper 6 completely covers the outer surface of the inner box assembly. Since the three edges of the inner box upper cover 2 and the inner box bottom 1 have been cut, only one edge is connected to form a cover opening structure. Find the open end of the inner box upper cover 2, and gently lift the inner box upper cover 2. During the lifting process, pay attention to the force to avoid damaging the inner box assembly. After opening, the product brochure decoration 5 inside the inner box assembly can be seen, which is printed with product related information.

[0062] 2、Take out the product: Carefully lift the product brochure decoration 5 in the box (if it does not hinder the taking of the product, it need not be lifted), at this time the jewelry product placed below can be seen. If a protective component 7 such as a sponge is placed in the box, it tightly wraps the jewelry product, playing a protective role against shock and collision. Gently remove the protective component 7, and then take out the jewelry product from the inner box bottom 1, and the whole process of taking out the product is completed.

[0063] 3. Closing the packaging box (if it needs to be used again): after using the product, if it needs to store the product or accommodate the packaging box again, first put the jewelry product back to the inner box lower bottom 1, ensure that the product is placed stably. Then, put the protection assembly 7 back around the product, make it closely fit the product, and provide protection for the product. Then, arrange the box inner product instruction decoration 5, and put it back to the original position. Finally, buckle the inner box upper cover 2 and the inner box lower bottom 1 again, make the edges of the two aligned, press gently, and ensure that the buckling is tight. At this time, the joint between the inner box upper cover 2 and the inner box lower bottom 1 forms a gap with a width of 0.3-0.5MM again, the closing operation of the packaging box is completed, and it waits for the next use.
