Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of packaging, and particularly to a buffer packaging structure. Background Art
[0002] Currently, during the transportation of electronic devices such as laptops and tablets, paper-plastic is configured as a buffer to prevent damage to the electronic devices in case of a sudden drop during transportation. The paper-plastic can effectively play a buffering role to protect the electronic devices.
[0003] Currently, when the production line packages electronic devices, first, the flat paper-plastic is folded along the rotation axes at both ends. By folding the inner paper-plastic, the two folding ears are perpendicular to the main body, and the positioning and fixing of the folding ears after flipping are achieved by the interference fit between the outer side of the main body boss and the inner side of the folding ears. Then, the paper-plastic and the electronic device are placed into a carton, and finally, the accessory box is inserted into the carton. However, this positioning method makes the folding ears prone to slipping and tilting after folding, resulting in the worker being unable to insert the accessory box into the carton, which affects the production rhythm. When the folding ears slip and tilt, it is necessary to fold the folding ears again to achieve the positioning and snap-fitting fixation with the main body boss through interference fit. However, after multiple foldings, this interference fit has almost no snap force, resulting in the failure of the folding ear positioning and snap-fitting. If the interference amount is increased to increase the snap force to reduce the probability of the folding ear misalignment, the increase in the snap force will increase the folding difficulty of the folding ears, and the snap-fitting and positioning of the folding ears and the main body boss cannot be achieved either.

Detailed implementation manners
[0030] To make the objectives, features, and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present disclosure.
[0031] According to an embodiment of the present disclosure, the present utility model provides a buffer packaging structure. As Figures 1 - 5 shown, a buffer packaging structure includes a main body section 1 and a folding ear section 2. The main body section 1 includes boss parts 11 respectively provided at both ends. The folding ear section 2 is provided outside the boss part 11 and the two are bendably connected. The folding ear section 2 has a folding ear boss 21, and the folding ear boss 21 is configured to be detachably connected to the boss part 11 when in the packaging state.
[0032] For the buffer packaging structure of the present application, when the folding ear section 2 is bent and erected for packaging, the positioning and fixing of the folding ear section 2 are realized through the engagement of the boss part 11 of the main body section 1 and the folding ear boss 21, thereby solving the problem that the folding ears of the current buffer packaging are prone to slip open after folding. And this setting method is simple, convenient, and easy to operate.
[0033] For example, considering the requirements of degradability and environmental protection, the material of the buffer packaging structure composed of the main body section 1 and the folding ear section 2 can be paper-plastic. Different from the current foamed cotton used as a buffer, foamed cotton absorbs energy through the material itself, while paper-plastic buffers and absorbs energy through the deformation of the structure itself. Therefore, in order to adapt to the sizes of different electronic devices, the main body section 1 of the buffer packaging structure of the present application is configured to be able to adaptively adjust its length and the gap between the main body sections according to the edge size of the electronic device, meet different packaging requirements, and provide an ideal wrapping depth, bringing good wrapping and buffering effects; especially when a drop occurs, it can effectively reduce the impact force.
[0034] For example, as Figures 1 - 2As shown, the main body section 1 further includes a clamping section 12. The clamping section 12 includes two main body protrusions 121 and there are multiple groups of the clamping section 12; the multiple groups of the clamping section 12 are arranged between the two boss portions 11 and are spaced along the length direction of the main body section 1; and the two main body protrusions 121 of each group of the clamping section 12 are arranged opposite to each other so as to form a second gap 122 therebetween. The second gap is used to accommodate and fix the bottom edge of the electronic device, and the width of the second gap 122 can be configured according to the edge thickness of the electronic device to be fixed. The clamping section 12 can be adaptively increased or decreased according to the edge length of the electronic device. The second gap 122 formed in the clamping section 12 is used to clamp the edge of the electronic device. For example, by embedding the bottom edge of the electronic device into the second gap 122, the bottom edge of the electronic device can be effectively fixed. And in this application, by arranging multiple groups of the clamping section 12 on the main body section 1, the clamping force is relatively evenly distributed, and in the case of a drop, a more ideal buffering effect is exerted, playing a sufficient protective role for the electronic device.
[0035] Further, as Figure 2 shown, the main body section 1 further includes a first connecting protrusion 14 and a second connecting protrusion 13. The second connecting protrusion 13 is connected between two relatively arranged main body protrusions 121. The second connecting protrusion 13 cooperates with the two main body protrusions 121 of the clamping section 12. On the one hand, it is used to support the bottom edge of the electronic device, and on the other hand, it effectively improves the buffering effect of the main body section. When the electronic device suddenly falls, the second connecting protrusion 13 can effectively prevent the downward movement of the electronic device, reduce the impact force of the electronic device, and protect the edge of the electronic device from damage. Among them, the first connecting protrusion 14 is connected between the clamping sections 12, as well as between the boss portion 11 and the clamping section 12. The first connecting protrusion 14 serves the purpose of connecting between two adjacent clamping sections 12 and between the boss portion 11 and the clamping section 12. The first connecting protrusion 14 is slightly lower than the second connecting protrusion 13. The first connecting protrusion 14 connects the boss portion 11 and the clamping section 12 to form an integral body, further increasing the impact resistance of the main body section 1. When the electronic device clamped in the clamping section 12 falls, the second connecting protrusion 13 first buffers the downward movement of the electronic device. Even when the second connecting protrusion 13 fails to prevent the continuous downward movement of the electronic device and causes downward deformation, the first connecting protrusion 14 then immediately plays a buffering role, further preventing the fall of the electronic device and further reducing the impact force of the electronic device, achieving a good protective effect.
[0036] Even further, as Figure 5As shown, on the second connecting convex part 13 and the main body convex parts 121 on both sides thereof, there are first concave parts 123 communicating with each other. Specifically, it is recessed inward from the middle position of the main body convex part 121 and extends towards the second connecting convex part 13, and is recessed downward from the middle position of the second connecting convex part 13, and these recessed areas communicate with each other to form the first concave part 123. Among them, the first concave part 123 can be arranged on part of the clamping section. This setting method can give full play to the buffering effect brought by the main body convex part 121 and the second connecting convex part 13.
[0037] For example, the main body section 1 is an integrally formed structure composed of a first connecting convex part 14, a second connecting convex part 13, a main body convex part 121 and a boss part 11. For example, it can be integrally formed by die casting. Further, for example, the buffer packaging structure is an integrally formed structure composed of the main body section 1 and the folding ear section 2.
[0038] For example, as Figure 2 shown, the main body section 1 and the folding ear section 2 can be convexly formed on a flat base material 3. Specifically, the first connecting convex part 14, the second connecting convex part 13, the main body convex part 121, the boss part 11 and the folding ear section 2 are convexly formed upward from the flat base material 3. The boss part 11 is arranged at both ends of the main body section 1, and the bendable connection between the boss part 11 and the folding ear section 2 can be achieved by constructing a folding line between the boss part 11 and the folding ear section 2, which is convenient for bending the folding ear section 2.
[0039] In one embodiment, as Figures 3 - 5 shown, the side surface of the folding ear boss 21 is the first inclined surface 211, and the top end surface of the boss part 11 is the second inclined surface 111. When the folding ear boss 21 and the boss part 11 are engaged, an interference fit is formed therebetween so that the first inclined surface 211 has a pressing force (i.e., a downward pressing force) on the second inclined surface 111. The folding ear boss 21 and the boss part 11 are constructed with an interference fit to ensure that when the folding ear section 2 is in a bent state, the boss part 11 can be effectively clamped on the folding ear boss 21 of the folding ear section 2, so that a stable connection relationship is formed between the folding ear section 2 and the main body section 1, as Figures 6 - 8 shown. Here, the "interference fit" means that when the folding ear section 2 is bent, the height of the top end surface of the boss part 11 is slightly greater than the height of the side surface of the folding ear boss 21 in contact with it in the vertical direction. For example, the height of the top end surface of the boss part 11 is designed to be 0.5 mm higher than the height of the side surface of the folding ear boss in the vertical direction.
[0040] In one embodiment, as Figures 3 - 5As shown, the second inclined surface 111 is inclined towards the main body section 1, and the inclination direction of the second inclined surface 111 is opposite to that of the first inclined surface 211. The first inclined surface 211 and the second inclined surface 111 have opposite inclination directions and the second inclined surface 111 is inclined towards the main body section 1, which can facilitate the snap - fit fixation of the boss portion 11 and the folding - ear boss 21. While facilitating the operation of the staff, it can make the folding - ear section 2 and the main body section 1 snap - fit tightly and not easy to slide open.
[0041] For example, as Figure 4 shown, the included angle β between the second inclined surface 111 and the horizontal plane is 20 - 45°, and the included angle γ between the first inclined surface 211 and the horizontal plane is 45 - 80°. The inclination angle of the second inclined surface 111 is slightly smaller than that of the first inclined surface 211. When the boss portion 11 and the folding - ear boss 21 are snap - fitted, the sum of the angles between the first inclined surface 211 and the second inclined surface 111 is about 90°. It can ensure the snap - fit positioning of the two and make the folding - ear section 2 perpendicular to the main body section 1, so as to closely fit the edge of the electronic device and ensure effective buffering for the electronic device.
[0042] In one embodiment, as Figure 2 shown, the folding - ear section 2 further includes two folding - ear protrusion portions 22. The two folding - ear protrusion portions 22 are oppositely formed on the outer side of the folding - ear boss 21 and are connected thereto. A first gap 23 is formed between the folding - ear protrusion portions 22. The first gap 23 and the two sides of the top of the boss portion 11 are configured to be in interference fit. When the folding - ear section 2 is bent and in the packaging state, the first gap 23 formed between the folding - ear protrusion portions 22 and the two sides of the top of the boss portion 11 are configured to be in interference fit, so that the boss portion 11 can be further clamped tightly in the first gap 23, and the boss portion 11 and the folding - ear boss 21 are also in interference fit, thereby further tightly fixing the folding - ear section 2 and the main body section 1 and improving the stable relationship between the two. In order to achieve the "interference fit", the width of the boss portion 11 is designed to be 0.8 mm more than the width between the first gaps 23, so as to ensure that when the folding - ear section 2 is in the bent state, the top end surface and the two sides of the top of the boss portion 11 can be effectively clamped in the folding - ear section 2, further improving the stable connection relationship between the folding - ear section 2 and the main body section 1.
[0043] Among them, when the folding - ear section 2 is bent and in the packaging state, since the main body section 1 and the folding - ear section 2 are snap - fitted and fixed, the first gap 23 formed in the folding - ear section 2 can closely fit the side edge of the electronic device. Cooperating with the second gap for stabilizing the bottom edge of the electronic device, it can provide good buffer protection for the electronic device in the package.
[0044] The two ear-fold convex portions 22 and the ear-fold boss 21 of the ear-fold section 2 are also formed by protruding from the planar base material 3. Specifically, the ear-fold convex portions 22 and the ear-fold boss 21 are formed by protruding upward from the planar base material 3. Therefore, the ear-fold section and the main body section are formed from the same planar base material, and a folding line is formed on the planar base material between the boss portion 11 and the ear-fold section 2, which facilitates bending the ear-fold section 2.
[0045] For example, in order to further improve the buffering effect of the ear-fold section 2, with reference to the first recess provided in the clamping section, a second recess can also be provided on the ear-fold convex portion 22 to give full play to the buffering effect of the ear-fold section.
[0046] In one embodiment, as Figures 9 - 10 shown, the buffer packaging structure is integrally formed by using a mold 4. The mold 4 includes a mold main body section 41 adapted to the main body section 1 and a mold ear-fold section 42 adapted to the ear-fold section 2. The included angle α between the bottom surface of the mold main body section 41 and the bottom surface of the mold ear-fold section 42 is between 145° and 160°; the draft angle δ of the mold 4 is 1° to 2°. The mold main body section 41 and the mold ear-fold section 42 are respectively adapted to the main body section and the ear-fold section of the buffer packaging structure to be formed, and their structures are generally the same. Among them, in order to avoid negative angles during mold making, which may cause difficulties in demolding, and to save the cost of the mold, the included angle α between the bottom surface of the mold main body section 41 and the bottom surface of the mold ear-fold section 42 is set between 145° and 160°, which can ensure smooth demolding.
[0047] In this embodiment, the buffer packaging structure can be formed by wet pressing (dry pressing) of slurry. During the manufacturing process, the opening and closing of the pulp mold move vertically up and down with respect to the main body, and the mold is provided with a draft angle of 1° to 2°. With this draft angle, smooth demolding can be ensured, the manufacturing efficiency can be improved, and the buffer protection effect can be taken into account.
