Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a cushioning foam structure and packaging. Background Technology

[0002] The packaging of electrical appliances on the market generally uses cushioning foam as the main cushioning material. For example... Figures 1-3 As shown, taking an electric heater as an example, the configuration of cushioning foam for packaging in related technologies is explained. Figure 1 The conventional method for setting up cushioning foam is given. The cushioning foam 2-1 configuration uses a relatively regular cube as the main body structure. Using the outer surface 1-1-1 of the product being wrapped or assembled (electric heater 1-1) as a reference, a simulated shape (also called a "feel") is created on one end face of the cube, and material is cut to form the cavity 2-1-1 for assembly. See [link to documentation]. Figure 2 Then, based on the placement requirements of additional accessories, the product's stress cushioning needs, and cost control requirements, partial material removal is performed on the remaining end faces to create cavities. Cavities designed with cost control in mind are known in the industry as material-stealing grooves. Figure 3 The structure and layout of the material stealing trough 2-1-2 are given.

[0003] The material-stealing trough designed according to the above configuration has a relatively regular shape, but the amount of material used is still very large, and the cost is difficult to reduce. Utility Model Content

[0004] In view of this, the present invention provides a cushioning foam structure and packaging to solve the problem that the configuration of cushioning foam in related technologies results in a relatively regular shape of the material trough, which still requires a large amount of material and makes it difficult to reduce costs.

[0005] In a first aspect, this utility model provides a cushioning foam structure, comprising:

[0006] The base shell includes an inner side and an outer side, the contours of which are both designed to mimic the outer surface of the product to be packaged; the inner side encloses a mating cavity capable of at least partially accommodating the product to be packaged, the mating cavity having an opening;

[0007] The reinforcing eaves are formed by extending outward from the base shell, and the plane of the reinforcing eaves coincides with or is parallel to the plane of the opening.

[0008] A reinforcing rib is provided on the outer periphery of the outer side, and multiple material-stealing grooves are formed between the reinforcing rib, the outer side, and the reinforcing eaves.

[0009] Beneficial effects: The cushioning foam structure of this utility model uses the outer shape of the product to be packaged to set the basic shell, ensuring the basic strength and basic protective function of the cushioning foam structure. Compared with the related technology that uses a more regular cube as the main body structure, unnecessary materials can be saved in the molding stage of the cushioning body. The reinforcing eaves effectively reduce the deformation of the basic shell, further improving the strength of the cushioning foam structure. The setting of reinforcing ribs forms a reliable support on the outer periphery of the basic shell, effectively strengthening the strength of the cushioning foam structure. At the same time, the multiple material-stealing grooves formed minimize material input, effectively reducing costs and enhancing competitiveness.

[0010] In one alternative embodiment, the reinforcing eaves are formed on the outer periphery of the opening.

[0011] Beneficial effects: When installing the cushioning foam structure, the base shell is subjected to greater force near the opening of the mating cavity, and the span on both sides of the base shell near the opening is larger. Therefore, the reinforcing eaves are formed on the outer periphery of the opening, which effectively improves the strength of the cushioning foam itself.

[0012] In one alternative embodiment, the smallest circumscribed rectangle of the reinforcing eaves extends vertically to near the top of the outer side to form an arrangement space, and all the reinforcing ribs are located within the arrangement space.

[0013] Beneficial effects: The arrangement space formed by extending the minimum outer rectangle of the reinforcing eaves to near the top of the outer side makes the outer contour of the cushioning foam structure more regular, avoiding gaps between it and the outer packaging, which could cause displacement and shaking during product transportation, thus improving the reliability of the support. Extending one end of the reinforcing rib to near the top of the outer side allows the reinforcing rib to form a semi-enclosed support structure from the outside of the base shell, further enhancing the strength of the cushioning foam structure without adding too much material, effectively controlling costs.

[0014] In one alternative embodiment, the reinforcing eaves are formed at the top of the outer side.

[0015] Beneficial effects: Placing the reinforcing eaves at the end of the outer side makes it easier to set reinforcing ribs using the reinforcing eaves as a base on one side, thus improving the ease of molding.

[0016] In one alternative embodiment, a plurality of the reinforcing ribs are distributed between the plane of the opening and the reinforcing eaves.

[0017] Beneficial effects: Multiple reinforcing ribs are set between the plane of the opening and the reinforcing eaves to form a stable and reliable reinforced structure, saving materials while ensuring strength and cushioning performance.

[0018] In one alternative embodiment, the plurality of reinforcing ribs are arranged in a cross pattern to form a grid structure.

[0019] Beneficial effects: When multiple reinforcing ribs are arranged in a cross pattern to form a grid structure, the reinforcing ribs avoid the corners and edges where the impact force is greatest, thus preventing the cushioning foam structure from being damaged by strong impact forces, which could cause the reinforcing ribs or even the entire cushioning foam to break.

[0020] In one optional embodiment, the base shell is provided with three reinforcing ribs spaced apart along its length and two reinforcing ribs spaced apart along its width.

[0021] Beneficial effects: The space for reinforcing ribs in the length direction of the foundation shell is greater than that in the width direction. Therefore, three reinforcing ribs are set at intervals in the length direction and two reinforcing ribs are set at intervals in the width direction. This results in high structural stability and strengthens the cushioning foam while effectively reducing the amount of material used.

[0022] In one alternative embodiment, the thickness of the base shell is 10mm to 15mm.

[0023] Beneficial effects: A base shell thickness of 10mm to 15mm ensures its own strength while providing basic protective performance, and requires less material. If the base shell thickness is less than 10mm, the strength will be insufficient; if it is greater than 15mm, the material usage will increase.

[0024] In one optional embodiment, the thickness of the reinforcing rib is 11mm to 20mm.

[0025] Beneficial effects: The thickness of the reinforcing ribs is determined comprehensively based on the weight of the product to be packaged, product characteristics, stress conditions, and transportation conditions. For conventional electrical products, a reinforcing rib thickness of 11mm to 20mm with a cushioning foam structure is sufficient to meet the requirements.

[0026] In one alternative embodiment, the cushioning foam structure is integrally molded.

[0027] Beneficial effects: The cushioning foam structure is molded in one piece, resulting in superior strength and impact resistance, and the processing technology is also simpler.

[0028] Secondly, this utility model also provides a packaging component, including any of the above-described cushioning foam structures.

[0029] Beneficial effects: Since the packaging includes the cushioning foam structure of this utility model, it has the same technical effect as the cushioning foam structure, saving materials, reducing costs, and enhancing product competitiveness while ensuring cushioning performance.

[0055] The following is combined with Figures 4 to 12 The following describes embodiments of the present invention.

[0056] According to embodiments of the present invention, on the one hand, such as Figure 4 As shown, a cushioning foam structure 2 is provided, comprising:

[0057] The base shell 20 includes an inner side 202 and an outer side 201, the outlines of which are conformed to the outer surface 10 of the product to be packaged. The inner side 202 encloses a mating cavity 21 capable of at least partially accommodating the product to be packaged. The mating cavity 21 has an opening. (See attached image.) Figure 7 and Figure 8 ;

[0058] The reinforcing eaves 22 extend outward from the base shell 20, and the plane of the reinforcing eaves 22 coincides with or is parallel to the plane of the opening. See [reference needed]. Figures 9-12 ;

[0059] Reinforcing ribs 23 are provided on the outer periphery of the outer surface 201, and multiple material-steeping grooves 24 are formed between the reinforcing ribs 23, the outer surface 201, and the reinforcing eaves 22. (See attached image) Figures 9-12 The assembly structure of the cushioning foam structure 2 and the product to be packaged (electric heater 1) is shown in the figure. Figure 5 .

[0060] The cushioning foam structure 2 of this utility model uses the outer surface 10 of the product to be packaged as the base shell 20 to ensure the basic strength and basic protective function of the cushioning foam structure 2. Compared with the related technology that uses a more regular cube as the main body shape structure, unnecessary materials can be saved in the molding stage of the cushioning body. The reinforcing eaves 22 effectively reduce the deformation of the base shell 20 and further improve the strength of the cushioning foam structure 2. The setting of the reinforcing ribs 23 forms a reliable support on the outer periphery of the base shell 20, which effectively strengthens the strength of the cushioning foam structure 2. At the same time, the multiple material-stealing grooves 24 formed minimize material input, effectively reduce costs and enhance competitiveness.

[0061] It should be noted that the buffer foam structure 2 of this utility model can be applied to electric heaters 1 or other relatively regular-shaped electrical products, such as rice cookers, and is especially suitable for products weighing less than 10kg.

[0062] In some embodiments, such as Figure 9 and Figure 10 As shown, the reinforcing eaves 22 are formed on the outer periphery of the opening. The smallest circumscribed rectangle of the reinforcing eaves 22 extends vertically to near the top of the outer side 201 to form an arrangement space, and all reinforcing ribs 23 are located within the arrangement space.

[0063] When installing the cushioning foam structure 2, the base shell 20 experiences greater stress near the opening of the mating cavity 21, and the span on both sides of the base shell 20 near the opening is also larger. Therefore, the reinforcing eaves 22 are formed on the outer periphery of the opening, effectively improving the strength of the cushioning foam itself. The minimum circumscribed rectangle of the reinforcing eaves 22 extends to the space near the top of the outer side 201, making the outer contour of the cushioning foam structure 2 more regular, avoiding gaps between it and the outer packaging, preventing displacement and shaking during product transportation, and improving support reliability. Extending one end of the reinforcing rib 23 to the vicinity of the top of the outer side 201, the reinforcing rib 23 forms a semi-enclosed support structure from the outside of the base shell 20, further enhancing the strength of the cushioning foam structure 2 without excessively increasing material, effectively controlling costs.

[0064] The basic design concept of the buffer foam structure 2 of this utility model is: Figure 6 Using the outer surface 10 of the product being wrapped or assembled as a reference, a base shell 20 is formed by thickening it to a certain thickness. The structure of the base shell 20 is shown in [reference]. Figure 7 and Figure 8 In the remaining areas, reinforcing ribs 23 are arranged according to a certain pattern to form a configuration consisting of facets and ribs. The material-free area enclosed between the facets and ribs is the material-stealing groove 24 in the original configuration. It can be naturally formed when the main configuration is established, and can effectively remove material from areas with less stress, achieving the technical effect of minimizing material usage and reducing costs. The areas with less stress on the cushioning foam structure 2 include the corners and edges. The distance from the product to the outer end face of the cushioning foam structure 2 in the corresponding direction is relatively large at these locations, and removing foam material at these locations has little impact on the overall stress.

[0065] Using the outer surface 10 of the product to be wrapped or assembled as a reference, a base shell 20 is formed by thickening it by 10mm to 15mm depending on the product weight. The inner surface 202 of the base shell 20 forms a heel-fitting cavity 21, and the outer surface 201 serves as one of the bases for the subsequent distribution of reinforcing ribs 23. The base shell 20 is assembled with the product to be packaged, providing basic protection and ensuring the basic strength of the foam itself.

[0066] Then, on the end face where the opening of the mating cavity 21 is located, a reinforcing ridge 22 with a thickness of 10-15mm is extended, depending on the product weight. The length and width of the reinforcing ridge 22 are determined according to the required cushioning thickness of the foam, and its length and width form the outer contour of the cushioning foam. The reinforcing ridge 22 can effectively reduce the overall deformation of the base shell 20 and further improve the strength of the cushioning foam structure 2, optimizing the stress distribution. In addition, the reinforcing ridge 22 also serves as another base for the subsequent distribution of reinforcing ribs 23.

[0067] Based on the above structure, and according to product characteristics, stress conditions, and the corresponding transportation conditions, reinforcing ribs 23 with a thickness of 11mm to 20mm are arranged according to certain rules, using the end face where the opening of the base shell 20 is located and the face where the reinforcing eaves 22 are located as the base. The height of the reinforcing ribs 23 is the height limit of the outer contour of the cushioning foam, and the height of the reinforcing ribs 23 is between 0 and 200mm. The heights of multiple reinforcing ribs 23 may not be completely consistent, and some local reinforcing ribs 23 may be smaller, depending on the actual situation. However, it is necessary to ensure that there are enough reinforcing ribs 23 to meet a certain height value, so as to ensure the stress strength of the cushioning foam structure 2 and the support effect of the outer packaging (such as cardboard boxes). The reinforcing ribs 23 are preferably avoided at corner positions. On the one hand, this avoids the corner positions with the greatest impact force, preventing the foam from being directly stressed and causing damage to the reinforcing ribs 23 or even the foam body. On the other hand, it can reduce the material cost of continuously reinforcing the foam structure in the corresponding corner areas.

[0068] Ultimately, in this configuration, the buffer foam structure 2 consists of a surface (reinforcing eaves 22, outer surface 201) and a rib (reinforcing rib 23). The material-free area formed between the surface and the rib is the material-stealing groove 24, achieving the technical effect of minimizing material usage and reducing costs.

[0069] In other embodiments, such as Figure 11 and Figure 12 As shown, the difference from the previous embodiment is that in this embodiment, the reinforcing eaves 22 are formed at the top of the outer side 201, and a plurality of reinforcing ribs 23 are distributed between the plane where the opening is located and the reinforcing eaves 22.

[0070] The reinforcing ridge 22 is positioned at the end of the outer side 201, facilitating the installation of reinforcing ribs 23 using the reinforcing ridge 22 as a base on one side, thus improving molding convenience. Multiple reinforcing ribs 23 are positioned between the plane of the opening and the reinforcing ridge 22, forming a stable and reliable reinforcing structure that saves materials while ensuring strength and cushioning performance.

[0071] The reinforcing gusset 22, located on the end face where the opening is located, is more suitable for heavier products, ensuring the foam provides effective support for the product itself. The reinforcing gusset 22, located near the top of the outer side 201, is suitable for lighter products, ensuring the foam provides effective support for the outer carton and other equivalent external wrapping materials. The appropriate option can be selected based on the actual needs of the product.

[0072] In some embodiments, multiple reinforcing ribs 23 are arranged in a cross pattern to form a grid structure.

[0073] Multiple reinforcing ribs 23 are arranged in a grid pattern to avoid the corners and edges where the impact force is greatest, thus preventing the reinforcing ribs 23 or even the entire buffer foam structure from being damaged by strong impact.

[0074] In some embodiments, such as Figure 10 As shown, the base shell 20 has three reinforcing ribs 23 spaced apart along its length and two reinforcing ribs 23 spaced apart along its width.

[0075] The space for reinforcing ribs 23 in the length direction of the base shell 20 is greater than that in the width direction. Therefore, three reinforcing ribs 23 are spaced apart in the length direction of the base shell 20 and two reinforcing ribs 23 are spaced apart in the width direction. This results in high structural stability, strengthens the cushioning foam, and effectively reduces the amount of material used.

[0076] In some embodiments, the thickness of the base housing 20 is 10 mm to 15 mm.

[0077] The thickness of the base shell 20 is between 10mm and 15mm, ensuring its own strength while providing basic protective performance, and using less material. If the thickness of the base shell 20 is less than 10mm, the strength will be insufficient; if it is greater than 15mm, the material usage will increase.

[0078] In some embodiments, the thickness of the reinforcing rib 23 is 11 mm to 20 mm.

[0079] The thickness of the reinforcing rib 23 is determined comprehensively based on the weight of the product to be packaged, product characteristics, stress conditions, and transportation conditions. For conventional electrical products, a thickness of 11mm to 20mm for the reinforcing rib 23 of the cushioning foam structure 2 is sufficient to meet the requirements.

[0080] It should be noted that the thickness of the base shell 20 and the thickness of the reinforcing rib 23 mentioned in this utility model are mainly applicable to the recommended selection range for products weighing less than 10kg. In actual application, they can be adjusted and selected according to the specific product weight and the transportation conditions required for packaging protection.

[0081] In some embodiments, the cushioning foam structure 2 is integrally molded.

[0082] Compared to the method of separating and then connecting the components, the cushioning foam structure 2 is molded in one piece, which has better strength and impact resistance, and the processing technology is also simpler.

[0083] According to an embodiment of the present invention, another aspect provides a packaging component, including a cushioning foam structure 2.

[0084] Since the packaging includes the cushioning foam structure 2 of this utility model, it has the same technical effect as the cushioning foam structure 2, saving materials, reducing costs, and enhancing product competitiveness while ensuring cushioning performance.

[0085] This utility model discloses a method for configuring a cushioning foam, comprising:

[0086] Using the outer surface 10 of the product to be packaged as a reference, a basic shell 20 is generated by contouring the product.

[0087] A reinforcing eave 22 extends from the base shell 20;

[0088] Using the reinforcing eaves 22 as a base, multiple reinforcing ribs 23 are formed by extending in a direction away from the reinforcing eaves 22.

[0089] Using the outer surface 10 of the product to be packaged as a reference, a basic shell 20 is generated by contouring, reducing the amount of material used. By setting up reinforcing eaves 22 and reinforcing ribs 23, the strength of the cushioning foam structure 2 is improved, effectively reducing the deformation of the basic shell 20. In addition, the multiple material-stealing grooves 24 formed minimize material input, effectively reducing costs and enhancing the market competitiveness of the product.

[0090] Specifically, a heel-shaped mating cavity 21 is formed on the inner side 202 of the base shell 20, and a reinforcing eave 22 extends outward from the opening of the mating cavity 21.

[0091] The reinforcing eaves 22 are set around the opening of the mating cavity 21, which has weak impact resistance, to effectively improve strength.

[0092] Specifically, before generating the basic shell 20 by contouring, the process also includes:

[0093] The thickness of the base shell 20 is determined based on the weight of the product to be packaged.

[0094] Based on the weight of the product to be packaged, the required strength of the base shell 20 can be calculated, and the thickness of the base shell 20 can be determined to meet the basic protection requirements.

[0095] Specifically, before extending the reinforcing eaves 22 onto the base shell 20, it also includes:

[0096] The thickness of the reinforcing eaves 22 is determined based on the weight of the product to be packaged and the required cushioning thickness.

[0097] The thickness of the reinforcing eaves 22 is determined based on the weight of the product to be packaged and the required cushioning thickness, so as to meet the strength and cushioning performance of the cushioning foam structure 2.

[0098] The buffer foam structure 2 configured in this utility model has a material-stealing groove 24 that can remove material from areas with minimal stress, thereby minimizing material usage and reducing costs.

[0099] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
