Description

Technical Field

[0001] The utility model relates to the technical field of packaging, and specifically, to a packaging component and a household electrical appliance component. Background Art

[0002] In response to the successive introduction of plastic restriction orders in current developed countries, countries such as France, Australia, and Spain have successively promulgated foam ban requirements, and products exported to local areas need to be newly developed into foam-free and plastic-free packaging. For example, Spain stipulates that a tariff will be imposed on non-recyclable packaging according to the weight per gram and the type of packaging material; France stipulates that as of January 1, 2025, packaging made entirely or partially of styrene polymers or copolymers will be prohibited, and these materials are non-recyclable and cannot enter the recycling channels; Australia stipulates that foam packaging for products below 45KG will be phased out gradually, with a transitional period until July 2025, and implementation will begin thereafter.

[0003] Therefore, various product packages have started to promote plastic substitution with paper to meet the environmental protection access requirements of relevant markets. However, paper materials do not have excellent comprehensive performance like traditional EPS materials, and they can neither provide buffering nor good support. Therefore, in the actual design process, it is necessary to construct a buffer area through a cardboard structure, but this design often has problems such as complex production processes, long assembly time, and unstable buffering performance.

[0004] There is currently a buffer packaging structure constructed by various cardboard structures, which has problems such as many cardboard parts, complex folding processes, cumbersome assembly, insufficient stacking and supporting performance, and high comprehensive design costs. Summary of the Utility Model

[0005] The first object of the utility model is to provide a packaging component that can improve the overall buffering, support, and protection performance of products while meeting the requirements of green, plastic-free environmental protection.

[0006] The second object of the utility model is to provide a household electrical appliance component that uses the above-mentioned packaging component.

[0007] To achieve the above first object, the present utility model provides a packaging assembly, comprising: a paper frame body, the paper frame body includes a first side frame, a bottom frame and a second side frame connected in sequence, the first side frame and the second side frame are oppositely arranged along the width direction of the paper frame body, the first side frame, the bottom frame and the second side frame are all hollow structures and all extend along the length direction of the paper frame body, and one end of the paper frame body is provided with an opening; an embedded buffer assembly, the embedded buffer assembly is installed on the paper frame body; the embedded buffer assembly includes an end plate part and a support part, the support part extends along the length direction and fits with the bottom frame, the end plate part is arranged at the end of the support part, the end plate part is clamped at the opening and covers the opening; at least a part of the end plate part and at least a part of the support part are made of honeycomb paperboard; the first side frame, the bottom frame, the second side frame and the end plate part enclose a product accommodation cavity; at least one of the side plates of the first side frame and the second side frame facing away from each other is provided with a buffer groove, and the buffer grooves are all recessed from the corresponding side plates towards the product accommodation cavity side.

[0008] As can be seen from the above solution, by setting the paper frame body with a hollow structure to improve the buffering performance, and arranging buffer grooves on the side plates outside the first side frame and the second side frame, thereby further improving the buffering effect of the first side frame and the second side frame. At the same time, considering that the bearing capacity of the hollow structure is poor and cannot meet the stacking and warehousing requirements, an embedded buffer assembly is designed, and honeycomb paperboard is arranged on the end plate part and the support part of the embedded buffer assembly, making use of the good support performance of the honeycomb, so as to improve the bearing capacity of the end plate part and the support part. The buffer grooves can also withstand the stacking pressure and dropping impact force from the side, ensuring the requirements of the product for dropping buffer impact during turnover.

[0009] The first side frame, the second side frame, the end plate part and the support part are designed with a plurality of wavy and buffer cardboard structures on each side of the packaging assembly, so as to buffer the impact of each side of the packaging assembly on the inner packaged product, and thus better protect the product.

[0010] The packaging assembly can effectively solve problems such as a large variety and quantity of packaging materials by using the groove structure formed by folding the end plate part and the support part of the embedded buffer assembly, the buffer groove structure formed on the outer side plate, the honeycomb paperboard and the mutually embedded paper cushion buffer structure, and finally realizes the requirement of plastic-free green export packaging, can meet the environmental protection regulations requirements of the export destination, and enables the product to enter the local market for sale.

[0011] At the same time, the plastic-free environmental protection packaging system can achieve better buffering and vibration absorption capabilities. At the same time, it can be mass-produced in batches, greatly reducing the use of foam, and has good market promotion. Compared with the traditional cardboard buffer structure that needs to be hand-folded and fixed, the packaging assembly of the present utility model is a composite cardboard structure with grooves and waves, which is a closed structure, saving the folding and forming operation time, and at the same time, the closed structure has relatively better buffering performance and reliability.

[0012] Preferably, the embedded buffer component further includes an end-plate honeycomb paperboard, a base-plate honeycomb paperboard, and a support paperboard; the support paperboard includes an end-plate folding edge and a base-plate folding edge connected to each other. The base-plate honeycomb paperboard is attached to the base-plate folding edge and forms a support portion together with the base-plate folding edge, and the end-plate honeycomb paperboard is attached to the end-plate folding edge and forms an end-plate portion together with the end-plate folding edge.

[0013] It can be seen that by compounding and pasting honeycomb paperboards inside the support paperboard to improve the pressure-bearing performance, the usage amount of foam inside the packing box is greatly reduced. The end-plate folding edge is used for pasting the end-plate honeycomb paperboard. After the base-plate folding edge is folded inward, a groove structure is formed and it is used for pasting the base-plate honeycomb paperboard. At the same time, it can strengthen the support performance of the embedded buffer component in the vertical direction and prevent appearance quality abnormalities such as the packing box bulging and deforming during the stacking process of products.

[0014] Further, the embedded buffer component further includes buffer corner pads, and the support paperboard further includes corner-pad folding edges; the corner-pad folding edges are arranged near the connection position of the end-plate folding edge and the base-plate folding edge; the buffer corner pads are of a hollow paper tube structure, the ends of the buffer corner pads are bonded and fixed to the corner-pad folding edges, and the peripheral walls of the buffer corner pads are arranged in contact with the inner cavity surface of the paper frame body.

[0015] It can be seen that the corner-pad folding edges are used for pasting the buffer corner pads. By providing the buffer corner pads as the corner protection structure of the packaging component, the pressure-bearing capacity and the anti-drop impact capacity of the packaging component are further improved.

[0016] Further, the buffer corner pads are in contact with the inner cavity surface of the first side frame; and / or the buffer corner pads are in contact with the inner cavity surface of the second side frame; and / or the buffer corner pads are in contact with the inner cavity surface of the bottom frame.

[0017] Further, the corner-pad folding edges extend from the edge of the end-plate folding edge in a direction away from the end-plate folding edge; or the corner-pad folding edges extend from the edge of the base-plate folding edge in a direction away from the base-plate folding edge.

[0018] Preferably, the support paperboard is corrugated paperboard; and / or the buffer corner pads are made of composite paperboard; and / or the paper frame body is made of composite paperboard.

[0019] It can be seen that the buffer corner pads and the paper frame body are made of composite paperboard materials. The composite paperboard is composed of a surface layer of kraft paper and an inner layer of slotted pipe paper. The support paperboard uses corrugated paperboard materials and is a one-piece corrugated paperboard. Because the composite paperboard and the corrugated paperboard have good processing performance, are easy to form, have high strength, good support performance, and can play a better protective role for products, other paperboard materials can also be used according to needs or actual situations.

[0020] A preferred solution is that the number of corner pad flanges and buffer corner pads is at least two, and one buffer corner pad is correspondingly arranged with one corner pad flange; two of the buffer corner pads are respectively arranged on both sides of the end plate part in the width direction.

[0021] It can be seen that the buffer corner pads are located at the top corner positions of the inner cavity of the corrugated paper frame body, and are of a hollow paper tube structure. Their outer sides are completely attached to the inner cavity surface of the paper frame body. When the product using this packaging component is subjected to severe corner drops or impacts, it can enhance the protection ability for the sharp corners around the paper frame body and avoid breakage and deformation.

[0022] A preferred solution is that the number of end plate parts is two, and the two end plate parts are respectively arranged at both ends of the support part; openings are provided at both ends of the paper frame body, and one end plate part is correspondingly arranged with one opening.

[0023] A preferred solution is that a guiding inclined surface is provided at one end of the end plate part far from the support part. The guiding inclined surface close to the first side frame inclines towards the first side frame, and the guiding inclined surface close to the second side frame inclines towards the second side frame.

[0024] It can be seen that through the setting of the guiding inclined surface, it is convenient to install the embedded buffer component into the paper frame body.

[0025] A preferred solution is that an avoidance notch is provided at one end of the side plate of the bottom frame close to the product accommodation cavity. The avoidance notch is recessed from the end of the side plate, and the end plate part is in fit and limit with the avoidance notch; the surface of the end plate part far from the product accommodation cavity is coplanar with the end surfaces of the first side frame, the bottom frame, and the second side frame.

[0026] A preferred solution is that the paper frame body includes a first side frame outer plate, a first side frame connecting plate, a first side frame inner plate, a bottom frame inner plate, a second side frame inner plate, a second side frame connecting plate, a second side frame outer plate, and a bottom frame outer plate that are connected end to end; the first side frame outer plate, the first side frame connecting plate, and the first side frame inner plate form the first side frame; the bottom frame inner plate and the bottom frame outer plate form the bottom frame; the second side frame inner plate, the second side frame connecting plate, and the second side frame outer plate form the second side frame; the support part is located between the bottom frame inner plate and the bottom frame outer plate, and the thickness of the support part is equal to the distance between the bottom frame inner plate and the bottom frame outer plate; the buffer groove of the first side frame is located on the first side frame outer plate, and the buffer groove of the second side frame is located on the second side frame outer plate.

[0027] It can be seen that the paper frame body of the selected packaging component is of an integral structure, reducing the use of adhesives and improving production efficiency. The buffer groove can be formed by die pressing, and partial batch forming by die can be realized, greatly reducing the folding and forming time during assembly and improving the operation efficiency. In addition, by arranging the support part in the inner cavity of the bottom frame, the connection stability between the paper frame body and the embedded buffer component is ensured.

[0028] A further solution is that the buffer groove of the first side frame has a first inclined side wall, a bottom wall, and a second inclined side wall that are sequentially connected; the bottom wall is arranged close to the inner side plate of the first side frame and forms a buffer space with the inner side plate of the first side frame; both the first inclined side wall and the second inclined side wall are inclined away from the product accommodation cavity.

[0029] It can be seen that by using inclined side walls to connect the bottom wall and the side plate, a wavy outer side plate is formed to improve the compressive performance of the entire side plate.

[0030] To achieve the above second object, the present utility model provides a household electrical appliance component, including a household electrical appliance and the above-mentioned packaging component, and at least a part of the household electrical appliance is located in the product accommodation cavity.

[0031] A preferred solution is that the number of packaging components is two, and the two packaging components are respectively sleeved on opposite sides of the household electrical appliance. Description of the Drawings

[0049] See Figures 1 to 3 , the household appliance component of this embodiment includes a household appliance 1 and two packaging components 2, and the two packaging components 2 are respectively sleeved on opposite sides of the household appliance 1. The household appliance 1 can be medium and small household appliance products such as a dehumidifier, an air purifier, etc. The packaging component 2 cleverly utilizes the hollow buffer structure formed after the high-strength composite cardboard is integrally formed in a mold, and forms an entire buffer packaging structure system through the embedded buffer component 4, so as to achieve the purpose of protecting the product.

[0050] The packaging component 2 includes a paper frame main body 3 and an embedded buffer component 4. The paper frame main body 3 includes a first side frame 31, a bottom frame 32, and a second side frame 33 that are connected in sequence. The first side frame 31 and the second side frame 33 are oppositely arranged along the width direction W of the paper frame main body 3, and the bottom frames 32 of the two packaging components 2 are oppositely arranged. The first side frame 31, the bottom frame 32, and the second side frame 33 are all hollow structures and all extend along the length direction of the paper frame main body 3.

[0051] The embedded buffer component 4 is installed on the paper frame main body 3. The embedded buffer component 4 includes a support portion 41 and two end plate portions 42. The support portion 41 extends along the length direction L and is bonded and fixed to the bottom frame 32. The support portion 41 is located in the inner cavity of the bottom frame 32.

One end plate portion 42 is clamped at one opening 34 and covers the corresponding opening 34. At both ends of the side plate of the bottom frame 32 close to the product accommodation cavity 30, that is, the top and bottom of the inner side plate 321 of the bottom frame, avoidance notches 324 are provided. The avoidance notches 324 are recessed from the end of the inner side plate 321 of the bottom frame. One end plate portion 42 is clamped and cooperatively limited with one avoidance notch 324. The surface 420 of the end plate portion 42 away from the product accommodation cavity 30 is coplanar with the end face 314 of the first side frame 31, the end face 320 of the outer side plate 322 of the bottom frame, and the end face 330 of the second side frame 33.

[0052] Two guiding inclined surfaces 421 are provided at one end of each end plate portion 42 away from the support portion 41. The guiding inclined surface 421 close to the first side frame 31 inclines towards the first side frame 31, and the guiding inclined surface 421 close to the second side frame 33 inclines towards the second side frame 33. Through the arrangement of the guiding inclined surfaces 421, it is convenient to install the embedded buffer component 4 into the paper frame main body 3. At least a part of the end plate portion 42 and at least a part of the support portion 41 are made of honeycomb cardboard. The first side frame 31, the bottom frame 32, the second side frame 33, and the end plate portion 42 enclose a product accommodation cavity 30, and at least a part of the household appliance 1 is located in the product accommodation cavity 30 of the packaging component 2.

[0053] See Figures 3 to 5 Figures 3 to 5 , the paper frame body 3 includes a first side frame outer plate 311, a first side frame connecting plate 312, a first side frame inner plate 313, a bottom frame inner plate 321, a second side frame inner plate 331, a second side frame connecting plate 332, a second side frame outer plate 333 and a bottom frame outer plate 322 which are connected end to end. The first side frame outer plate 311, the first side frame connecting plate 312 and the first side frame inner plate 313 form the first side frame 31, the bottom frame inner plate 321 and the bottom frame outer plate 322 form the bottom frame 32, and the second side frame inner plate 331, the second side frame connecting plate 332 and the second side frame outer plate 333 form the second side frame 33.

Buffer grooves 300 are provided on both the first side frame outer plate 311 and the second side frame outer plate 333, and the buffer grooves 300 are recessed from the corresponding side frame outer plates toward the product accommodation cavity 30. The buffer groove 300 of the first side frame 31 has a first inclined side wall 301, a bottom wall 302 and a second inclined side wall 303 connected in sequence. The bottom wall 302 is close to and parallel to the first side frame inner plate 313 and forms a buffer space 310 with the first side frame inner plate 313. Both the first inclined side wall 301 and the second inclined side wall 303 are inclined in a direction away from the product accommodation cavity 30.

[0054] See Figure 2 and Figures 6 to 9 Figures 6 to 9 , the embedded buffer assembly 4 further includes a support cardboard 5, a substrate honeycomb cardboard 6, four buffer corner pads 7 and two end plate honeycomb cardboards 8. The support cardboard 5 is a one-piece corrugated cardboard, and both the buffer corner pads 7 and the paper frame body 3 are made of composite cardboard. The composite cardboard is composed of a surface layer of kraft paper and a inner layer of slotted pipe paper. The composite cardboard and the corrugated cardboard have good processing performance, are easy to form, have high strength, good support performance, and can play a better role in protecting the product. Other cardboard materials can also be used according to needs or actual situations.

[0055] The support cardboard 5 includes a substrate folded edge 411, two end plate folded edges 412 and four corner pad folded edges 413 which are connected. The substrate folded edge 411 extends along the length direction L of the paper frame body 3. The two end plate folded edges 412 are respectively arranged at both ends of the substrate folded edge 411 and are perpendicular to the substrate folded edge 411. The four corner pad folded edges 413 are all arranged near the connection positions of the end plate folded edges 412 and the substrate folded edge 411. Two of the corner pad folded edges 413 are respectively arranged at both ends of the first end plate folded edge 412, and the other two corner pad folded edges 413 are respectively arranged at both ends of the second end plate folded edge 412, and each corner pad folded edge 413 extends from the edge of the corresponding end plate folded edge 412 in a direction away from the corresponding end plate folded edge 412.

[0056] The substrate honeycomb cardboard 6 is bonded and attached to the substrate folded edge 411 and forms a support portion 41 together with the substrate folded edge 411. An end plate honeycomb cardboard 8 is bonded and attached to an end plate folded edge 412, and the end plate honeycomb cardboard 8 and the corresponding end plate folded edge 412 form an end plate portion 42. As Figure 9 shown, the buffer corner cushion block 7 is a hollow paper tube structure. The buffer corner cushion blocks 7 are arranged in one-to-one correspondence with the corner cushion folded edges 413. The end portions of the buffer corner cushion blocks 7 are fixedly bonded to the corresponding corner cushion folded edges 413. The peripheral wall of the buffer corner cushion block 7 is attached to the inner cavity surface of the paper frame main body 3, and the buffer corner cushion block 7 is attached to the inner cavity surfaces of the first side frame 31, the second side frame 33, and the bottom frame 32.

[0057] By internally compounding and pasting honeycomb cardboard on the support cardboard 5, the pressure-bearing performance is improved, and the usage amount of foam inside the packaging box is greatly reduced. The end plate folded edge 412 is used for pasting the end plate honeycomb cardboard 8. After the substrate folded edge 411 is folded inward, a groove structure is formed and is used for pasting the substrate honeycomb cardboard 6. At the same time, it can enhance the support performance of the embedded buffer assembly 4 in the vertical direction and prevent abnormal appearance quality such as bulging and deformation of the packaging box during the stacking process of products. In addition, by setting the buffer corner cushion block 7 as the corner protection structure of the packaging assembly 2, the buffer corner cushion block 7 is located at the top corner position of the inner cavity of the wavy paper frame main body 3 and is a hollow paper tube structure. Its outer side surface is completely attached to the inner cavity surface of the paper frame main body 3. When the product using the packaging assembly 2 is subjected to severe corner drop or impact, it can enhance the protection ability of the sharp corners around the paper frame main body 3 and avoid breakage and deformation.

[0058] To further analyze the actual flat compression strength of the composite cardboard composed of the composite cardboard and the honeycomb cardboard, composite cardboard and honeycomb cardboard (with a thickness of 30 mm) with a sample size of 150 mm x 150 mm were used for relevant performance tests. The relevant test data are shown in Table 1, and the force-displacement curves of each sample during the flat compression process are as Figure 10 shown, and the deformation nephograms of each sample at each stage are as Figure 11 shown.

[0059] Table 1 Performance test data of each composite cardboard

[0060] sample specimen width mm maximum force N compressive strength MPa A 150 864.61 0.14 B 150 648.27 0.11 C 150 642.11 0.11 D 150 937.88 0.16 mean value 150 773.21 0.13

[0061] From Table 1 and Figure 10 and 11It can be seen that after the honeycomb paperboard and the composite paperboard are singly laminated, as the displacement increases, the load value first increases at a relatively fast rate, then gradually stabilizes, accompanied by small fluctuations. Moreover, as the displacement continues to increase, it will eventually enter the compressive stable state of the honeycomb paperboard, and the load value in this state is more than twice that of the single honeycomb paperboard. Therefore, by using the method of laminating the honeycomb paperboard and the composite paperboard in this embodiment, the buffering, vibration absorption ability and support strength of the packaging component can be greatly improved.

[0062] As can be seen from the above, by setting the paper frame body with a hollow structure to improve the buffering performance, and arranging buffer grooves on the side plates outside the first side frame and the second side frame, the buffering effect of the first side frame and the second side frame is further improved. At the same time, considering the poor pressure-bearing capacity of the hollow structure and its inability to meet the requirements of stacking and warehousing, an embedded buffer component is designed, and honeycomb paperboard is arranged on the end plate part and the support part of the embedded buffer component, taking advantage of the good support performance of the honeycomb, so as to improve the pressure-bearing performance of the end plate part and the support part. The buffer groove can also withstand the stacking pressure and drop impact force from the side, ensuring the requirements of the product for drop buffering impact during turnover.

[0063] Wave-shaped and buffer cardboard structures are designed at multiple places on the sides of the packaging component for the first side frame, the second side frame, the end plate part and the support part, so as to buffer the impact of each side of the packaging component on the inner packaged product, and thus better protect the product.

[0064] The packaging component can effectively solve problems such as a large variety and quantity of packaging materials by using the groove structure formed after folding the end plate part and the support part of the embedded buffer component, the buffer groove structure formed on the outer side plate, the honeycomb paperboard and the mutually embedded paper cushion buffer structure. Finally, it realizes the requirement of plastic-free green export packaging, can meet the environmental protection regulations of the export destination, and enables the product to enter the local market for sale.

[0065] At the same time, the plastic-free environmental protection packaging system can achieve good buffering and vibration absorption effects. At the same time, it can be mass-produced on a large scale, greatly reducing the use of foam, and has good market popularity. Compared with the traditional cardboard buffer structure that needs to be manually folded and fixed, the packaging component of the present utility model is a composite cardboard structure with grooves and waves, which is a closed structure, saving the operation time of folding and forming. At the same time, the closed structure has relatively better buffering and reliability.

[0066] In addition, the corner pad flange can also extend from the edge of the substrate flange in a direction away from the substrate flange, and the side wall of the buffer corner pad block is fixedly adhered to the corner pad flange. The number of the corner pad flanges and the buffer corner pad blocks can also be at least two, and one buffer corner pad block is correspondingly arranged with one corner pad flange; wherein the two buffer corner pad blocks are respectively arranged on both sides of the end plate part in the width direction. Only one guiding inclined surface can also be arranged on each end plate part, and the guiding inclined surface inclines towards the side frame close to the guiding inclined surface. The guiding inclined surface can also be arranged only on one of the end plate parts. The two packaging components can be respectively arranged on the upper and lower sides of the household appliance, or can be arranged on the left and right sides of the household appliance. The number, shape, size, etc. of the buffer grooves on each outer side plate can all be changed as required. The above changes can also achieve the purpose of the present utility model.

[0067] Finally, it should be emphasized that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
