Abstract
Description
Technical Field
[0001] This invention belongs to the field of product packaging technology, specifically relating to a disc-shaped fragile product outer packaging and its production method. Background Technology
[0002] Round, fragile products such as glass and ceramic plates are generally shallow containers used for holding food, and can also be used for decoration. These materials are easily damaged during packaging, transportation, or handling, leading to breakage. Traditionally, these products are often stacked, with thin sponges or cardboard placed between layers to prevent collisions. Straw or similar materials are often used to fill the product and outer packaging. For short-distance transport, this packaging method provides some protection; although a small number of products may break, for lower-priced items, the packaging cost and the resulting loss are reasonably balanced. However, for long-distance transport, such as for export products, or for higher-priced items, breakage significantly increases costs. Using more expensive packaging, such as foam packaging, requires sufficient thickness to achieve adequate protection. This increased volume and cost significantly raises transportation costs, thereby increasing product prices and reducing market competitiveness. Therefore, our company has developed a low-cost, highly protective, disc-shaped packaging for fragile products. Summary of the Invention
[0003] The purpose of this invention is to provide a disc-shaped fragile product outer packaging and its production method, which aims to package disc-shaped fragile products to form external protection, solve the problem that such products are prone to breakage during transportation, and is low in cost and easy to produce.

At the same time, a first limiting plate and a first notch are formed on the second inner support plate at the third cutting line c; the fourth cutting line d forms a second limiting plate and a second notch on the front side plate, and the first limiting plate extends outward from the inside through the second notch. The inner shell bottom plate is twisted 180° along the eleventh fold line and rotated 90° towards the outer shell bottom plate along the twelfth fold line so that the inner shell assembly is completely located on the outer shell bottom plate; The outer shell protective plate and the second outer shell side plate are bent sequentially toward the inner shell assembly along the fourth fold line and the third fold line, with the outer shell protective plate attached to the upper part of the inner shell assembly; the outer shell top cover and the first outer shell side plate are bent sequentially toward the outer shell protective plate along the first fold line and the second fold line, so that the outer shell top cover is attached to the outer shell protective plate.

For example, the sheet material of this application can be obtained by die cutting, and then the outer packaging of this application can be obtained by simple bending, rotation and insertion, which reduces the production requirements of workers.

[0016] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the given embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0017] In the description of this application, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0018] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.
[0019] It should be noted that the terms "electrolyte" and "gelling agent" are existing and conventionally used materials in the field, and the above-mentioned technical features are also the inventive points of this invention. Therefore, the composition of "electrolyte" and "gelling agent" will not be described in detail.
[0020] See Figure 1As shown, this application discloses a disc-shaped product outer packaging, including an outer shell assembly and an inner shell assembly obtained by cutting and bending a sheet of material of a predetermined thickness. In this embodiment, the sheet material is preferably cardboard, which can be hardboard, corrugated cardboard, etc., with sufficient thickness and strength. Of course, it can also be a plastic sheet, such as a hollow plastic board. When selecting which material to use to produce the outer packaging, the overall production cost is considered first, provided that the packaging requirements can be met. For example, when using corrugated cardboard, it is a commonly used packaging box material, which is lightweight and cheaper, making it more suitable as the outer packaging material for this application. The corrugated cardboard is first printed with the required patterns and text on its surface, and then the semi-finished material of the outer packaging is obtained by die-cutting using existing technology. Of course, depending on the required packaging appearance, white cardboard or coated paper can also be used as the outermost material of the corrugated paper to obtain the best appearance texture and printing effect.
[0021] Specifically, a dividing line is provided in the middle of the plate-like material, dividing the plate-like material into an outer shell region 10 and an inner shell region 20. The dividing line includes a twelfth fold line l12 located in the middle of the plate-like material and a first cutting line a symmetrically arranged on the extension lines at both ends of the twelfth fold line l12. Figure 1 As shown, the first cutting line a is composed of the end a1 where the outer edge of the plate-shaped material is located to the end a2 of the twelfth broken line l12.
[0022] The outer shell area 10 is composed of an outer shell top cover 11, a first outer shell side plate 12, an outer shell bottom plate 13, a second outer shell side plate 14 and an outer shell protective plate 15, which are divided by a first fold line l1, a second fold line l2, a third fold line l3 and a fourth fold line l4 that are perpendicular to the dividing line and arranged in parallel in sequence. The inner shell area 20 consists of an inner shell bottom plate 25 and inner protective components 20a symmetrically arranged on both sides of the inner shell bottom plate 25. The lines connecting the two corners of the inner shell bottom plate 25 at the end where it connects to the outer shell bottom plate 13 and pointing towards its center are respectively the eleventh fold line l11 and the second cutting line b. The eleventh fold line l11 is adjacent to the outer shell protective plate 15. Each inner protective component 20a includes a first inner support plate 211, a second inner support plate 212, a lower bottom plate 22, a front side plate 231, an upper top plate 232, and a rear side plate 24, which are divided by the third cutting line c and the fifth fold line l5, the sixth fold line l6, the seventh fold line l7, the fourth cutting line d, the eighth fold line l8, the ninth fold line l9, and the tenth fold line 10 located at both ends of the third cutting line c. The third cutting line c is located in the area of the second inner support plate 212, and the fourth cutting line d is located in the area of the front side plate 231, thereby dividing the second inner support plate 212 and the front side plate 231 into components with arc-shaped structures.
[0023] It should be noted that the first to fifth cutting lines all involve completely severing the sheet material within its defined length; the sheet material at the locations of the first to thirteenth fold lines is in a complete connected state (or cut with dotted lines for easy bending), and the corresponding positions of the sheet material are bent at these points. During assembly, the outer packaging is obtained by bending and twisting at the locations of the aforementioned fold lines and cutting lines. Details are as follows.
[0024] See Figure 2 As shown, the first inner support plate 211 is bent 90° along the fifth fold line l5. Due to the presence of the third cutting line c, a region with an arc-shaped structure is formed in part of the second inner support plate 212. However, there is no fold line between the root of this region and the first inner support plate 211, i.e., there is no bend. Therefore, when the first inner support plate 211 is bent 90°, this region will rotate 90° relative to the second inner support plate 212 along with the first inner support plate 211, thereby forming the first limiting plate 2121. At the same time, the first notch 2122 is formed on the second inner support plate 212. Then, the second inner support plate 212 is bent 90° relative to the lower bottom plate 22 along the sixth fold line l6, and the lower bottom plate 22 is bent 90° relative to the front side plate 231 along the seventh fold line l7, thereby obtaining... Figure 2 The state shown.
[0025] See Figure 3 As shown, the front side plate 231 is bent 90° relative to the upper top plate 232. Due to the presence of the fourth cutting line d, a region with an arc-shaped structure is divided in part of the upper top plate 232. However, there is no fold line between the root of this region and the front side plate 231, i.e., there is no bend. When the front side plate 231 is bent 90°, this region will rotate 90° relative to the upper top plate 232 along with the front side plate 231, thereby forming the second limiting plate 2311. At the same time, a second notch 2312 is formed on the front side plate 231. At this time, the second inner support plate 212 is rotated in the direction of the front side plate 231, so that the first inner support plate 211 is attached to the inner surface of the upper top plate 232. The first limiting plate 2121 extends outward from the second notch 2312, basically keeping flush and parallel with the second limiting plate 2311, thereby obtaining... Figure 3 The state shown is as follows. It should be noted that the statement that the first limiting plate 2121 and the second limiting plate 2311 are basically parallel means that they are in a near-parallel state (more of an ideal state, which is more conducive to describing the product structure). Alternatively, it can be understood that the first limiting plate 2121 and the second limiting plate 2311 work together to restrict the disc-shaped product. The direction of their force on the disc-shaped product is the same. However, due to the local deformation and bending differences of the plate material, there may be a small angle between them. But this small angle does not affect their joint action to restrict the disc-shaped product.
[0026] See Figure 4 As shown, further in Figure 3 In this state, continue to bend the top plate 232 relative to the rear side plate 24 by 90° to obtain Figure 4 The state shown is as follows. The first inner support plate 211 is attached to the inner surface of the upper top plate 232, and the first limiting plate 2121 extends outward from the second notch 2312 (i.e., the first limiting plate 2121 is inserted into the second notch 2312), thereby limiting the second inner support plate 212. This causes it to be tilted and supported within the rectangular tube enclosed by the lower bottom plate 22, the rear side plate 24, the front side plate 231, and the upper top plate 232, thereby improving the stability and strength of the entire inner protective component area 20a. Thus, while meeting its strength and stability requirements, it is possible to use thinner and lighter sheet materials, thereby reducing packaging weight.
[0027] See Figure 5 As shown, further in Figure 4 In this state, the rear side plate 24 is bent 90° relative to the inner shell bottom plate 25. At this time, the upper top plate 232 is directly above the lower bottom plate 22, and the first limiting plate 2121 and the second limiting plate 2311 are basically parallel to the inner shell bottom plate 25, thus obtaining an inner protective component area 20a. Similarly, another symmetrical inner protective component 20a is obtained by bending it according to the same method and steps as described above, which will not be repeated here. At this time, we obtain Figure 6-8 The structure is shown. It should be noted that for the two symmetrical inner protective components 20a, the first limiting plate 2121 and the second limiting plate 2311, together with the first notch 2122 and the second notch 2312, form a clamping area f. In the actual packaging process, the edge portion of the disc-shaped product is inserted into this clamping area f (i.e., inserted into the second notch 2312, and a larger portion of the edge can even be inserted into the first notch 2122). Combined with the superposition of the first limiting plate 2121 and the second limiting plate 2311, the disc-shaped product is clamped. Similarly, when using the thinnest possible plate material, the superposition of the first limiting plate 2121 and the second limiting plate 2311 enhances the strength and stability of the clamping area f, effectively reducing material usage and packaging weight, which helps reduce product packaging costs and transportation costs. In a further optimization, after clamping, the bottom of the disc-shaped product can be suspended, which can prevent the outer shell of the packaging from being squeezed by the outer shell when it is subjected to severe impact and deforms inward, thereby significantly improving the protective capability of the disc-shaped product.
[0028] like Figure 9-10 As shown, in Figure 6-8 Based on the above, the inner shell bottom plate 25 is twisted 180° around the eleventh fold line l11. Figure 10(As indicated by the arrow in the image), due to the presence of the second cutting line b, during the twisting process, the inner shell bottom plate 25 is completely cut off at the location of the second cutting line b, thus forming a first side 251 and a second side 252 at this location. The inner shell bottom plate 25 is also divided into a first part 25a and a second part 25b. When twisted to 180°, the bottom surface of the inner shell bottom plate 25 located in the first part 25a will fit against the surface of the inner shell bottom plate 25 located in the second part 25b. Simultaneously with the twisting, the second part 25b of the inner shell bottom plate 25 is bent 90° along the twelfth fold line l12 towards the side where the outer shell bottom plate 13 is located, obtaining... Figure 11 The state shown.
[0029] like Figure 12 As shown, in Figure 11 Based on this, the inner shell bottom plate 25 and the inner protective assembly 20a are further bent along the twelfth fold line l12 toward the outer shell bottom plate 13 until the second part 25b of the inner shell bottom plate 25 is attached to the outer shell bottom plate 13, thus obtaining... Figure 12-13 The state shown is now complete. At this point, the disc-shaped product can be inserted into the clamping area f, completing the loading of the disc-shaped product. Then, the next packaging step can be performed.
[0030] like Figure 14 As shown, in Figure 12-13 Based on this, the outer shell panel 15 is bent upwards at 90° relative to the second outer shell side panel 14 along the fourth fold line l4. Due to the presence of the fifth cutting line e, a trapezoidal region is thus divided into parts of the outer shell panel 15. However, there is no fold line between the root of this region and the second outer shell side panel 14, i.e., there is no bend. Therefore, during the upward bending of the outer shell panel 15 along the fourth fold line l4, this region will not bend, thus forming an insert notch g on the outer shell panel 15, thereby obtaining... Figure 14 The state shown.
[0031] like Figure 15 As shown, in Figure 14 Based on the above, the second outer shell side plate 14 is bent upwards at 90° along the third fold line l3. After bending, the outer shell protective plate 15 covers the inner protective component 20a and fits against the upper top plate 232, thus obtaining... Figure 15 The state shown.
[0032] like Figure 16 As shown, in Figure 15Based on the above, the first outer shell side plate 12 is bent upwards by 90° along the second fold line l2, and the outer shell top cover 11 is bent upwards by 90° relative to the first outer shell side plate 12 along the first fold line l1, so that the outer shell top cover 11 moves in the direction of the outer shell protective plate 15. Since an insert 16 is provided on the outer shell top cover 11, when the outer shell top cover 11 is attached to the outer shell protective plate 15, the insert 16 is inserted into the insert notch g, limiting the outer shell top cover 11, thereby completing the sealing of the outer packaging. Of course, a patch can also be attached at the position of the insert 16 and the insert notch g to further prevent the insert 16 from coming out of the insert notch g and prevent the outer packaging from loosening. At this time, the rear side plates 24 of the two inner protective components 20a become the two side plates of the outer packaging, which, together with the outer shell top cover 11, the first outer shell side plate 12, the outer shell bottom plate 13 and the second outer shell side plate 14, form the entire outer shell of the outer packaging.
[0033] Therefore, this application can obtain an outer packaging that can fully protect the disc-shaped product by simply bending and twisting a single sheet of material, through the cutting lines and fold lines obtained by processing. Preferably, it uses corrugated cardboard, which is commonly used in the market, readily available and inexpensive, as the material for producing the outer packaging. This significantly reduces production costs and makes the packaging lighter, effectively reducing packaging costs while also reducing the problem of increased transportation costs caused by the weight of the outer packaging.
[0034] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
