Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging technology, and in particular to a cushioning packaging structure for a steam oven. Background Technology
[0002] Currently, most steam ovens on the market use EPS (expanded polystyrene) foam as cushioning material for their packaging. However, EPS foam has poor recyclability, is not environmentally friendly, and causes pollution. For environmental reasons, eco-friendly packaging is gradually entering the market to replace traditional EPS foam. Currently, eco-friendly packaging is generally molded from pulp, which is expensive and only suitable for lightweight products. It also offers poor protection and cannot pass drop tests. Utility Model Content

[0087] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.
[0088] like Figure 1 and Figure 2 As shown in the figure, this embodiment discloses a cushioning packaging structure for a steam oven 1, which serves to cushion and prevent collisions during the transportation of the steam oven 1.
[0089] like Figure 1 and Figure 2 As shown, the cushioning packaging structure includes a pad for contacting the outer surface of the steam oven 1. The pad comprises a main body and a covering, both made of paper. The main body is formed by splicing multiple honeycomb cardboard pieces, and the covering covers the outer surface of the main body, connecting the multiple honeycomb cardboard pieces of a single main body into a whole.
[0090] Specifically, such as Figure 1 and Figure 2 As shown, the pad includes two end pads 2, two front pads 3, and two rear pads 4.
[0091] like Figures 1-6As shown, two end plates 2 are respectively provided at the upper and lower ends of the steam oven 1. The two end plates 2 are provided with grooves 21 for accommodating the steam oven 1 on the side facing each other in the first direction (i.e., the height direction of the steam oven 1). The upper and lower ends of the steam oven 1 are accommodated in the grooves 21, and the two end plates 2 abut against the upper and lower end surfaces of the steam oven 1 respectively.
[0092] like Figures 4-6 As shown, the main body 22 of the end plate includes an upper frame 221 and a lower frame 222 arranged sequentially along a first direction. The upper frame 221 includes a first upper honeycomb paperboard 2211, a second upper honeycomb paperboard 2212, a third upper honeycomb paperboard 2213, and a fourth upper honeycomb paperboard 2214 connected end to end. The first upper honeycomb paperboard 2211 and the third upper honeycomb paperboard 2213 are spaced apart in a second direction (i.e., the front-to-back direction of the steam oven 1), and the second upper honeycomb paperboard 2212 and the fourth upper honeycomb paperboard 2214 are spaced apart in a third direction (the left-to-right direction of the steam oven 1). The lower frame 222 includes a first lower honeycomb paperboard 2221, a second lower honeycomb paperboard 2222, a third lower honeycomb paperboard 2223, and a fourth lower honeycomb paperboard 2224 connected end to end. The first lower honeycomb paperboard 2221 and the third lower honeycomb paperboard 2223 are spaced apart in a second direction, and the second lower honeycomb paperboard 2222 and the fourth lower honeycomb paperboard 2224 are spaced apart in a third direction. The end pad wrapping member 24 wraps the upper frame 221 and the lower frame 222 to form an integral structure.
[0093] In this embodiment, the upper frame 221 is a split structure, meaning the first upper honeycomb paperboard 2211, the second upper honeycomb paperboard 2212, the third upper honeycomb paperboard 2213, and the fourth upper honeycomb paperboard 2214 are independent of each other. The lower frame 222 is an integral structure, meaning the first lower honeycomb paperboard 2221, the second lower honeycomb paperboard 2222, the third lower honeycomb paperboard 2223, and the fourth lower honeycomb paperboard 2224 are a single unit. Designers can adjust the size of the upper frame 221 to adapt to different models of equipment according to the actual product being protected. In other alternative embodiments, the upper frame 221 can also be an integral structure, or the lower frame 222 can also be a split structure.
[0094] like Figure 4As shown, the lower frame 222 extends horizontally beyond the end face of the upper frame 221 facing the end face of the end face of the upper frame 221 in the horizontal direction, so that the end face of the lower frame 222 facing the upper frame 221 in the first direction forms an abutment surface 2225, which is used to abut against the upper or lower end face of the steam oven 1. Specifically, the first lower honeycomb paperboard 2221 and the third lower honeycomb paperboard 2223 extend towards the end face of the upper frame 221 beyond the upper frame 221, with their ends facing each other in the second direction. The second lower honeycomb paperboard 2222 and the fourth lower honeycomb paperboard 2224 extend towards the end face of the upper frame 221 beyond the upper frame 221, with their ends facing each other in the third direction.
[0095] In this embodiment, the lower frame 222 extends beyond the upper frame 221 to form an abutment surface 2225, directly supporting the bottom / top surface of the equipment, enhancing its weight support capacity and preventing packaging collapse. The double-layer frame structure improves overall compressive strength and effectively disperses vertical impact forces during transportation.
[0096] The extent to which the lower frame 222 extends beyond the upper frame 221 can be set according to the specific product dimensions. To prevent the cushioning packaging structure from being too large, the extent to which the lower frame 222 extends beyond the upper frame 221 can be less than 40mm, while ensuring stable support for the steam oven 1.
[0097] like Figure 4 As shown, the thickness directions of the first upper honeycomb paperboard 2211, the second upper honeycomb paperboard 2212, the third upper honeycomb paperboard 2213, the fourth upper honeycomb paperboard 2214, the first lower honeycomb paperboard 2221, the second lower honeycomb paperboard 2222, the third lower honeycomb paperboard 2223, and the fourth lower honeycomb paperboard 2224 are all parallel to the first direction. The thickness direction of the honeycomb paperboard is parallel to the height direction, fully utilizing its vertical flat crush strength advantage to specifically resist the weight of the equipment and drop impacts.
[0098] The heights of the upper frame 221 and the lower frame 222 can be the same or different.
[0099] like Figures 3-5As shown, the end plate 2 has a first clearance hole 231 and a second clearance hole 232 on both sides in the third direction. The first clearance hole 231 and the second clearance hole 232 are located at the same end of the second upper honeycomb paperboard 2212 in the second direction. The two ends of the first clearance hole 231 in the first direction pass through the second upper honeycomb paperboard 2212 and the second lower honeycomb paperboard 2222, and the first clearance hole 231 passes through the end face of the second upper honeycomb paperboard 2212 and the second lower honeycomb paperboard 2222 in the third direction toward the interior of the end plate 2. The two ends of the second clearance hole 232 in the first direction pass through the fourth upper honeycomb paperboard 2214 and the fourth lower honeycomb paperboard 2224, and the second clearance hole 232 passes through the fourth upper honeycomb paperboard 2214 and the fourth lower honeycomb paperboard 2224 in the third direction toward the interior of the end plate 2. The first clearance hole 231 and the second clearance hole 232 are used to avoid interference with the front panel of the steam oven 1. The specific dimensions of the first clearance hole 231 and the second clearance hole 232 can be designed according to the actual product.
[0100] like Figure 3 and Figure 6 As shown, the end pad 24 covers the port of the first clearance hole 231 and the second clearance hole 232 away from the end of the upper frame 221 in the first direction, to prevent the front panel of the steam oven 1 from being exposed, to strengthen the edge structure of the hole, and to prevent stress concentration from causing the cardboard to tear when it falls.
[0101] In other alternative embodiments, the end pad cover 24 may also not cover the port of the first clearance hole 231 and the second clearance hole 232 at the end away from the upper frame 221 in the first direction.
[0102] like Figure 1 , Figure 2 , Figures 7-9 As shown, two front pads 3 are respectively positioned at the two front corners of the steam oven 1. Both front pads 3 are used to abut against the front surface of the steam oven 1 and respectively against the left and right end surfaces of the steam oven 1. The main body 31 of the front pad includes a first front honeycomb paperboard 311, a second front honeycomb paperboard 312, and a third front honeycomb paperboard 313. The second front honeycomb paperboard 312 and the third front honeycomb paperboard 313 are both fixed to the same end of the first front honeycomb paperboard 311 in the third direction. The second front honeycomb paperboard 312 and the third front honeycomb paperboard 313 are spaced apart in the second direction, and this spacing forms a space to accommodate and avoid the front panel of the steam oven 1, thus avoiding assembly interference. The wrapping component 32 of the front pad wraps the first front honeycomb paperboard 311, the second front honeycomb paperboard 312, and the third front honeycomb paperboard 313 to form an integral structure.
[0103] like Figure 1 , Figure 2 , Figures 7-9 As shown, the third front honeycomb paperboard 313 is disposed on the side of the second front honeycomb paperboard 312 facing the rear pad 4 in the second direction. The second front honeycomb paperboard 312 abuts against the front end of the panel, and the third front honeycomb paperboard 313 abuts against the rear end of the panel. The length of the third front honeycomb paperboard 313 in the third direction is less than the length of the second front honeycomb paperboard 312 in the third direction. The thickness directions of both the first front honeycomb paperboard 311 and the third front honeycomb paperboard 313 are parallel to the third direction, giving full play to their vertical flat crush strength advantage and specifically resisting the weight of the equipment and drop impact. The second front honeycomb paperboard 312 includes two front honeycomb paperboard units 3121 stacked along the second direction. The thickness direction of the front honeycomb paperboard units 3121 is parallel to the second direction. The stacking of the front honeycomb paperboard units 3121 allows for adjustment of local thickness to adapt to the protection requirements of different models of equipment.
[0104] The thicknesses of the first front honeycomb paperboard 311, the second front honeycomb paperboard 312, and the third front honeycomb paperboard 313 can be the same or different, and the thicknesses of the different front honeycomb paperboard units 3121 included in a single second front honeycomb paperboard 312 can be the same or different.
[0105] In other alternative embodiments, the number of front cell paperboard units 3121 included in the second front cell paperboard 312 may be one or more.
[0106] like Figure 1 , Figure 2 , Figures 10-12 As shown, two rear pads 4 are respectively positioned at the two rear corners of the steam oven 1. Both rear pads 4 abut against the rear end face of the steam oven 1 and respectively against the left and right end faces of the steam oven 1. Since the rear pads 4 do not need to avoid the front panel of the steam oven 1, the main body 41 of the rear pad includes a first rear honeycomb cardboard 411 and a second rear honeycomb cardboard 412. The second rear honeycomb cardboard 412 abuts against one end of the first rear honeycomb cardboard 411 in the third direction. The first rear honeycomb cardboard 411 abuts against the left and right end faces of the steam oven 1, and the second rear honeycomb cardboard 412 abuts against the rear end face of the steam oven 1. The length of the second rear honeycomb cardboard 412 in the second direction is less than the length of the first rear honeycomb cardboard 411 in the second direction. Compared to the front pad 3, the rear pad 4 has a simpler structure while ensuring rear-end cushioning, meeting the impact resistance requirements of the metal body at the rear of the equipment. The back pad 42 wraps the first rear honeycomb paperboard 411 and the second rear honeycomb paperboard 412 to form an integral structure.
[0107] like Figure 1 , Figure 2 , Figures 10-12As shown, the thickness direction of the first rear honeycomb paperboard 411 is parallel to the third direction, and the thickness direction of the second rear honeycomb paperboard 412 is parallel to the second direction, fully utilizing its vertical flat crush strength advantage to specifically resist the weight of the equipment and drop impacts. The first rear honeycomb paperboard 411 includes two rear honeycomb paperboard units 4111 stacked along the third direction, with the thickness direction of the rear honeycomb paperboard unit 4111 parallel to the third direction. The stacking of the rear honeycomb paperboard units 4111 allows for adjustment of local thicknesses to adapt to the protection requirements of different equipment models.
[0108] The thickness of the first rear honeycomb paperboard 411 and the second rear honeycomb paperboard 412 can be the same or different, and the thickness of the different rear honeycomb paperboard units 4111 included in a single first rear honeycomb paperboard 411 can be the same or different.
[0109] In other alternative embodiments, the number of rear honeycomb paperboard units 4111 included in the first rear honeycomb paperboard 411 may be one or more.
[0110] In this embodiment, as Figure 6 , Figure 9 and Figure 12 As shown, all padding panels are covered with corrugated cardboard. Each padding panel is covered as a single unit, with serrated edges (5) at the bends. The corrugated cardboard further enhances the cushioning effect. The single-sheet corrugated cardboard covering avoids seams, ensuring overall padding strength and preventing components from falling apart. The serrated edges (5) design allows for precise folding and wrapping of the honeycomb panels, improving production efficiency.
[0111] In other alternative implementations, the covering material may also be other paper materials.
[0112] In this embodiment, the pad is made entirely of paper material, completely replacing traditional EPS foam, meeting environmental protection requirements and avoiding environmental pollution. The quantity and size of the corresponding honeycomb cardboard in the pad can be adjusted according to the actual product, eliminating the need for molds for each product and reducing production costs. The structure of the honeycomb cardboard provides excellent cushioning. Through the full-wrap design of 12 edges of the top, bottom, front, and back edges of the pad, it precisely matches the contour of the steam oven 1, utilizing the excellent flat-pressing properties of the honeycomb cardboard to disperse impact force and improve the cushioning effect. This embodiment uses a combination of corrugated cardboard and honeycomb cardboard placed in different directions to ensure structural strength and cushioning performance, fully utilizing the characteristics of the materials.
[0113] The cushioning packaging structure of this embodiment can pass a preset drop test: a drop height of 450mm from one corner and three edges, and a drop height of 500mm from all six sides. A trampling test is also conducted: a tester weighing approximately 100kg (with added weight) walks back and forth on the packaging box for 30 seconds.
[0114] This embodiment requires the packaging supplier to deliver the goods after assembly. For the production line, the main operation steps of the packaging part are to place 6 pads, and the process is relatively simple.
