Description

Technical Field

[0001] The utility model specifically relates to a cushioning packaging structure. Background Art

[0002] As the name implies, packaging structures are used to package products, such as packaging boxes, packaging boxes, etc., which have the function of wrapping or partially wrapping goods to protect products. The buffer structure is used as the shock-proof buffer in the packaging structure, such as foam materials, fixed grooves in boxes, inflatable bags, bubble films, etc. More and more packaging structures use more environmentally friendly materials such as paper fibers. Paper fibers are processed into fiber-shaped finished products by processing equipment from waste paper scraps, cartons, paper rolls, newspapers, book paper and other materials. Traditional buffer packaging structures made of paper fibers are made of single layers in specific shapes, or double layers are simply stacked, but these structures have high strength, low deformation degree, poor buffering effect, and poor resilience after deformation, which is not conducive to effective protection of products.

[0003] The utility model is produced based on the above-mentioned shortcomings. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a cushioning packaging structure with better protection effect.

[0005] The utility model is realized by the following technical solutions:

[0006] A cushioning packaging structure includes a base plate, a support assembly and a cover plate. The support assembly is arranged between the base plate and the cover plate and a plurality of the support assemblies are arranged side by side. The support assembly includes two support members, the upper ends of the support members are connected to the cover plate and the lower ends of the support members are connected to the base plate. The middle part of the support member has a deformable bending section.

[0007] In the cushioning packaging structure as described above, the two support members of the support assembly are symmetrically arranged.

[0008] In the cushioning packaging structure as described above, the cross section of the curved section of the support member is arc-shaped, and in one support assembly, the curved sections of the two support members protrude in a direction away from each other.

[0009] In the cushioning packaging structure as described above, the central angle α of the curved section satisfies: α≤150°.

[0010] In the cushioning packaging structure as described above, the cover plate includes a panel and eaves side plates connected around the panel and extending toward the bottom plate.

[0011] In the cushioning packaging structure as described above, the radius of the curved section is R, a gap is left between the lower edge of the eaves side plate and the bottom plate, and the width distance H of the gap satisfies: H≤R / 2.

[0012] In the cushioning packaging structure as described above, the bottom plate, cover plate and support member are all an integrated structure made of paper fibers.

[0013] In the cushioning packaging structure as described above, the lower end of the support member is provided with a lower folding plate bent at a right angle, the bottom plate is flat against the lower folding plate, and the bottom plate and the lower folding plate are connected by bonding.

[0014] In the cushioning packaging structure as described above, the upper end of the support member is provided with an upper folding plate bent at a right angle, the cover plate is flat against the upper folding plate, and the cover plate and the upper folding plate are connected by bonding.

[0015] In the cushioning packaging structure as described above, the support member has a straight section connected to the curved section and arranged vertically. In one support assembly, the straight sections of two support members are flat against each other and are connected by bonding.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] The cushioning packaging structure of the utility model is designed to support the assembly and its bending section. When the cushioning packaging structure is squeezed by external pressure during transportation or storage, due to the existence of the bending section, it can be easily bent and deformed, and can recover to a certain extent after the pressure is released. This feature gives the packaging structure efficient energy absorption capacity and excellent cushioning performance, thereby improving the overall cushioning performance, thereby better protecting the product;

[0018] Secondly, the curved section 21 of the support member adopts an arc-shaped cross section, and its central angle α is ≤150°, which enables the curved section to be more fully elastically deformed when subjected to force, just like a spring, and can be compressed and deformed under the action of external force, absorbing a large amount of impact energy, thereby reducing the impact on the items in the package;

[0019] Furthermore, the radius of the curved section is R, and the gap width H between the eaves side plate and the bottom plate is ≤ R / 2. This design allows the curved section to have enough space to bend and deform when the package is under pressure, and this gap can also serve as a buffer zone to further disperse and absorb the impact force. At the same time, the bottom plate and the cover plate are only allowed to move within a certain range to prevent the curved section from causing material damage due to excessive deformation.

[0025] The utility model is further described below in conjunction with the accompanying drawings:

[0026] The directions described in the utility model specification, such as "up", "down", "left", "right", "front", "back", etc., are based on the directions of the drawings and are intended to facilitate the description of the relationship between the various components. They do not indicate the unique or absolute positional relationship between the various components. They are only one of the implementation methods of the utility model and are not a limitation on its implementation method.

[0027] This embodiment provides a cushioning packaging structure, the entire cushioning packaging structure is made of paper fiber material, of course, the structure is also applicable to other paper materials, such as Figures 1 to 5 As shown, it includes a base plate 1, a support assembly 2 and a cover plate 3. The support assembly 2 is arranged between the base plate 1 and the cover plate 3 and several support assemblies 2 are arranged side by side. There are at least two support assemblies 2, which are arranged side by side between the base plate 1 and the cover plate 3. The support assembly 2 includes two support members 20. The upper end of the support member 20 is connected to the cover plate 3 and the lower end of the support member 20 is connected to the base plate 1. The middle part of the support member 20 has a deformable bending section 21. The key design is that the middle part of the support member 20 is provided with a deformable bending section 21, and the bending section 21 has good elasticity and plasticity. When the cushioning packaging structure is squeezed by external pressure during transportation or storage, due to the existence of the bending section 21, it can easily bend and deform, and can restore to its original shape to a certain extent after the pressure is released. This feature gives the packaging structure efficient energy absorption capacity and excellent cushioning performance. The bottom plate 1 and the cover plate 3 move closer to each other under pressure, causing the curved section 21 of the support member 20 to deform, thereby converting the impact force generated by the external force into the elastic potential energy of the curved section 21, thereby protecting the internal items from damage. In general, the design of this cushioning packaging structure is scientific and reasonable, effectively improving the protection ability of the product during the logistics process, and providing better protection for the product.

[0028] As a preferred solution of this embodiment, Figures 1 to 3 As shown, the two support members 20 of the support assembly 2 are symmetrically arranged, so that the two support members 20 are mirror-imaged relative to the central axis or reference surface in spatial position, which is not only conducive to balancing the force of the overall structure, but also ensures that when the cushioning packaging structure is squeezed from different directions, the support members 20 on both sides can be deformed evenly and synchronously, thereby providing a more stable and balanced cushioning effect. Specifically, no matter whether the packaging structure is subjected to vertical downward, upward or lateral pressure, since the two support members 20 are symmetrical, their curved sections 21 can effectively disperse and absorb the impact force, preventing excessive concentration of force from causing local damage. At the same time, the symmetrical arrangement is also conducive to improving the stability of the packaging structure in a dynamic environment, ensuring that it can play an excellent safety protection performance under various complex transportation conditions.

[0029] As a preferred solution of this embodiment, Figure 3 As shown, the cross-section of the curved section 21 of the support member 20 is an arc-shaped. In a support assembly 2, the curved sections 21 of the two support members 20 protrude in a direction away from each other. The curved section 21 of the support member 20 is designed with an arc-shaped cross-section. This shape has excellent mechanical properties and can better bear and disperse pressure. At the same time, it can also ensure that when the force is deformed, the bending of the curved section 21 is smoother, which greatly reduces the stress concentration phenomenon, thereby improving the overall buffering effect and durability of the structure. Moreover, in a support assembly 2, the curved sections 21 of the two support members 20 are deliberately designed to protrude in a direction away from each other, so that when external pressure is applied from either side, the curved sections 21 of the two support members 20 will be effectively deformed in their respective directions, forming a force mode similar to an "arch bridge", further enhancing the compressive resistance of the structure. This specific orientation design allows the support member 20 to maximize the consumption of impact energy through its own deformation when under pressure, while also facilitating rapid recovery to its original shape after pressure is released, maintaining good elastic recovery performance, and ultimately ensuring that the cushioning packaging structure provides all-round and efficient protection for internal items.

[0030] As a preferred solution of this embodiment, Figure 4As shown, the center angle α of the curved section 21 satisfies: α≤150°. Specifically, the center angle α of the arc-shaped cross section of the curved section 21 has a limiting condition, that is, α is not greater than 150 degrees. This means that the curved portion of each support member 20 exists in the form of an arc not exceeding 150 degrees. The main purpose is that a larger center angle may lead to excessive concentration of local stress, that is, when the center angle α of the arc-shaped cross section of the curved section 21 is greater than 150°, it is easy to cause excessive concentration of local stress in the support member 20, and then the curved section 21 is easy to bend and cause structural damage. When the center angle α is less than 150°, it is conducive to dispersing stress and improving structural stability and durability. Of course, the center angle α of the arc-shaped cross section of the curved section 21 cannot be too small, that is, the center angle α is not less than 60°, otherwise it cannot have a good deformation effect.

[0031] As a preferred solution of this embodiment, Figure 3 As shown, the cover plate 3 includes a panel 31 and an eaves side panel 32 connected around the panel 31 and extending toward the bottom plate 1, the panel 31 and the eaves side panel 32. The panel 31, as the main plane part of the cover plate, usually plays a role in direct contact and protection of the packaged items. Its area and strength are customized according to the actual needs of the packaged items, while the eaves side panel 32 connected around the panel 31 and extending toward the bottom plate 1 plays a key role in enhancing the stability of the packaging structure, dust and moisture resistance, and enhancing the buffering effect. The eaves side panel 32 surrounds the panel 31 to form a relatively closed space, which can not only be closely combined with the bottom plate 1 and the support assembly 2 to jointly resist impact and pressure from all directions, but also effectively prevent dust or other debris from entering the interior of the package to cause pollution or damage to the product. In addition, when the packaging structure is squeezed, the eaves side panel 32 works in conjunction with the curved section 21 of the support member 20 to absorb and disperse the impact force, further improving the buffering performance and safety of the entire buffer packaging structure.

[0032] In the cushioning packaging structure as described above, the radius of the curved section 21 is R, and a gap is left between the lower edge of the eaves side panel 32 and the bottom plate 1, and the width distance H of the gap satisfies: H≤R / 2. In this way, when encountering an external impact, the bottom plate 1 and the cover plate 3 are allowed to move within a certain range, preventing the curved section 21 from being damaged due to excessive deformation, thereby further enhancing the stability and impact resistance of the entire packaging structure.

[0033] As a preferred solution of this embodiment, the bottom plate 1, the cover plate 3 and the support member 20 are all an integrated structure made of paper fibers.

[0034] As a preferred solution of this embodiment, the lower end of the support member 20 is provided with a lower folding plate 22 bent at a right angle, the bottom plate 1 is flat against the lower folding plate 22, and the bottom plate 1 is connected to the lower folding plate 22 by bonding.

[0035] As a preferred solution of this embodiment, the upper end of the support member 20 is provided with an upper folding plate 23 bent at a right angle, the cover plate 3 is flat against the upper folding plate 23, and the cover plate 3 is connected to the upper folding plate 23 by bonding.

[0036] As a preferred solution of this embodiment, the support member 20 has a straight section 24 connected to the curved section 21 and arranged vertically. In a support assembly 2, the straight sections 24 of two support members 20 are flat against each other and are connected by bonding.

[0037] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
