Description

Technical Field

[0001] This application relates to the field of packaging materials technology, and in particular to a cushioning packaging. Background Technology

[0002] In the modern logistics and transportation industry, the safe transport of fragile goods is always a key aspect of ensuring product quality and customer satisfaction. With the booming development of e-commerce and increasingly frequent global trade, the market demand for efficient and reliable shock-absorbing packaging materials has grown dramatically. High-quality shock-absorbing packaging not only effectively reduces the breakage rate of goods during transportation and minimizes economic losses, but also enhances a company's brand image and customer trust.

[0003] Inflatable columns, as a new type of shock-absorbing packaging material, have rapidly gained widespread application in the packaging industry due to their significant advantages of small volume before inflation, ease of storage and transportation. Since their introduction, continuous technological improvements and process optimizations have gradually enhanced the production efficiency and product quality of inflatable columns, and their application scope has expanded from initially small, fragile items to the packaging of various high-value goods such as electronic products and glassware.

[0004] However, despite the progress made in inflatable column packaging technology, it still has significant limitations in practical applications. Existing inflatable columns mainly absorb impact force through the elastic deformation of the air layer. Due to limitations in their internal structural design and gas filling methods, their shock absorption effect often fails to meet actual needs when facing complex transportation environments such as severe vibrations and high-intensity impacts. Utility Model Content

[0005] Therefore, it is necessary to provide a cushioning packaging solution to address the issue that existing inflatable column packaging has only a mediocre cushioning and shock absorption effect and cannot meet higher shock absorption requirements.

[0006] A cushioning package includes a bottom of an air column, an inner side of the air column, and an outer side of the air column. The inner side of the air column is connected to the bottom of the air column and is set at an angle to the bottom of the air column. The inner side of the air column and the bottom of the air column together enclose a placement space with an open top. The outer side of the air column is located on the side of the inner side of the air column away from the placement space. Along the depth direction of the placement space, one end of the outer side of the air column is connected to the end of the inner side of the air column away from the bottom of the air column, and the other end of the outer side of the air column extends beyond the bottom of the air column.

[0007] In one embodiment, the cushioning package further includes an air column support layer connected to the outer side of the air column away from the inner side of the air column, the air column support layer being lower than the bottom of the air column and used to support the outer side of the air column.

[0008] In one embodiment, the air column support bottom layer extends from the outer side of the air column to the inner side of the air column, and the cushioning package also includes an air column support side layer connected to the end of the air column support bottom layer away from the outer side of the air column, and the air column support side layer extends toward the bottom of the air column, with a gap between the air column support side layer and the bottom of the air column.

[0009] In one embodiment, the cushioning package further includes an air column support top layer, which connects the inner side of the air column and the outer side of the air column, with the inner side of the air column and the outer side of the air column spaced apart.

[0010] In one embodiment, the top layer of the air column support is arranged parallel to the bottom of the air column, and the outer side and inner side of the air column are arranged parallel to each other. Along the depth direction of the placement space, the height of the outer side of the air column is greater than the height of the inner side of the air column.

[0011] In one embodiment, both the inner and outer portions of the air column are annular structures, with the outer portion of the air column sleeved on the outside of the inner portion.

[0012] In one embodiment, the cushioning packaging further includes an air column support top layer, which connects the inner side of the air column and the outer side of the air column; along the depth direction of the placement space, the bottom of the air column includes a first bottom layer and a second bottom layer spaced apart, the air column support top layer includes a first support top layer and a second support top layer spaced apart, along the direction from the outer side of the air column to the inner side of the air column, the inner side of the air column includes a first inner layer and a second inner layer spaced apart, the outer side of the air column includes a first outer layer and a second outer layer spaced apart, the first bottom layer, the first inner layer, the first support top layer and the first outer layer are connected in sequence, and the second bottom layer, the second inner layer, the second support top layer and the second outer layer are connected in sequence.

[0013] In one embodiment, the cushioning package further includes an air column connecting layer that connects the first bottom layer and the second bottom layer.

[0014] In one embodiment, the cushioning package is an integral structure with multiple independent air columns located at the bottom, inner side, and outer side of the air columns.

[0015] In one embodiment, the cushioning package has an uninflated state and an inflated state, wherein each inflatable column in the uninflated state is in an uninflated state, and each inflatable column in the inflated state is inflated state; when the cushioning package is inflated, the cushioning package has an unbent state and a bent state formed after bending, wherein in the unbent state, the outer surfaces of the first inner layer and the first outer layer are coplanar, and the outer surfaces of the second inner layer and the second outer layer are coplanar.

[0016] The cushioning packaging provided in the above solution has an inner part and an outer part of the air column connected sequentially to the bottom of the air column. The outer part of the air column is located on the outer periphery of the inner part of the air column, and one end of the outer part of the air column extends beyond the bottom of the air column. This allows the outer part of the air column to directly contact the placement surface, taking the ground as an example, so that the bottom of the air column is suspended. This improves the shock absorption and cushioning effect of the cushioning packaging and provides better protection for the items in the placement space. Attached Figure Description

[0025] See Figure 1 , Figure 1 A schematic diagram of the structure of a cushioning package 100 according to an embodiment of this application is shown. This cushioning package 100, provided in an embodiment of this application, can be used to wrap items during transport to provide cushioning and shock absorption, thereby protecting fragile items. Figure 1 As shown, the cushioning package 100 includes a bottom 110 of the air column, an inner side 120 of the air column, and an outer side 130 of the air column.

[0026] Combination Figure 2 As shown, Figure 2 The cushioning packaging 100 shown in one embodiment of this application is in which the bottom 110 of the air column is horizontally arranged, but this is not a limitation. In other embodiments, it can also be adjusted according to the structure of the items to be contained.

[0027] like Figure 1 and Figure 2As shown, the inner side 120 of the air column is connected to the bottom 110 of the air column and is set at an angle to the bottom 110 of the air column. The inner side 120 of the air column and the bottom 110 of the air column together enclose a placement space 170 with an open top, which is used to hold items.

[0028] In some embodiments, the inner side 120 of the air column has a vertically arranged annular structure, and the bottom of the inner side 120 is connected to the bottom 110 of the air column, so that the inner side 120 and the bottom 110 of the air column together enclose the placement space 170. In other embodiments, the inner side 120 of the air column may also be inclined relative to the bottom 110 of the air column.

[0029] like Figure 1 and Figure 2 As shown, the outer side 130 of the air column is located on the side of the inner side 120 of the air column away from the placement space 170. Along the depth direction of the placement space 170, one end of the outer side 130 of the air column is connected to the end of the inner side 120 of the air column away from the bottom 110 of the air column, and the other end of the outer side 130 of the air column extends beyond the bottom 110 of the air column, so that the outer side 130 of the air column can directly contact the placement surface, and the bottom 110 of the air column is suspended, thereby improving the shock absorption and cushioning effect of the cushioning packaging 100 and playing a better role in protecting the items in the placement space 170.

[0030] As an example, the placement surface can be the supporting surface of various components such as boxes, barrels, shelves, tables or trays, or it can be the ground or other surfaces, which will not be listed here.

[0031] like Figure 2 As shown, in one embodiment, the cushioning package 100 further includes an air column support bottom layer 140, which is connected to the end of the outer side 130 of the air column away from the inner side 120 of the air column. The air column support bottom layer 140 is lower than the bottom 110 of the air column and is used to support the outer side 130 of the air column, thereby increasing the contact area between the cushioning package 100 and the placement surface, thus making the cushioning package 100 more stable.

[0032] In some implementations, the air column support base 140 is horizontally positioned to facilitate placement on the placement surface.

[0033] like Figure 2 As shown, in one embodiment, the air column support bottom layer 140 extends toward the direction of the inner side 120 of the air column and toward the interior of the cushioning package 100, so that the overall structure of the cushioning package 100 is compact and occupies less area. In other embodiments, the air column support bottom layer 140 may also extend in a direction away from the inner side 120 of the air column, which can also play the role of stabilizing the cushioning package 100.

[0034] like Figure 2 As shown, in one embodiment, the cushioning package 100 further includes an air column support side layer 150. The air column support side layer 150 is connected to the side of the air column support bottom layer 140 away from the outer side of the air column 130, and extends towards the direction of the bottom of the air column 110. There is a gap between the air column support side layer 150 and the bottom of the air column 110, which not only preserves the bottom of the air column 110 to obtain a better shock absorption effect, but also provides a new way to use the cushioning package 100. For example, the cushioning package 100 can be inverted from the illustrated state. At this time, the item can also be placed in the space enclosed by the bottom of the air column 110 and the air column support side layer 150. If the item itself has a structure with a large bottom size, it can also be stuck in the gap between the air column support side layer 150 and the bottom of the air column 110, thereby playing a limiting role.

[0035] like Figure 1 and Figure 2 As shown, in one embodiment, the cushioning packaging 100 further includes an air column support top layer 160, which connects the inner air column portion 120 and the outer air column portion 130. The inner air column portion 120 and the outer air column portion 130 are spaced apart, and the gap between them serves to cushion and absorb shock, thereby improving the cushioning effect around the placement space 170. In other embodiments, the inner air column portion 120 and the outer air column portion 130 can also be directly connected; exemplarily, they can be arranged at an angle.

[0036] like Figure 1 and Figure 2 As shown, in one embodiment, the top layer 160 of the air column support and the bottom layer 110 of the air column are arranged parallel to each other. In this embodiment, both the top layer 160 and the bottom layer 110 of the air column support are horizontally arranged, but this is not a limitation. The outer side 130 and the inner side 120 of the air column are arranged parallel to each other. In this embodiment, both the outer side 130 and the inner side 120 of the air column are vertically arranged, but this is not a limitation. The outer side 130 and the inner side 120 of the air column can also be in a parallel inclined state.

[0037] like Figure 1 and Figure 2 As shown, along the depth direction of the placement space 170, the height of the outer part 130 of the air column is greater than the height of the inner part 120 of the air column, so that one end of the outer part 130 of the air column can extend beyond the bottom 110 of the air column, making the bottom 110 of the air column suspended, thereby improving the shock absorption and cushioning effect of the cushioning packaging 100.

[0038] like Figure 1 and Figure 2As shown, in one embodiment, both the outer side 130 and the inner side 120 of the air column are annular structures. The outer side 130 is sleeved on the outside of the inner side 120. It should be noted that the outer side 130 is not limited to a circular annular structure. It can be a square ring, an elliptical ring, or an irregular annular structure, which is set according to the structure of the bottom 110 of the air column.

[0039] Combination Figure 1 and Figure 2 As shown, along the depth direction of the placement space 170, the bottom 110 of the air column includes a first bottom layer 111 and a second bottom layer 112 spaced apart, and the top support layer 160 of the air column includes a first support top layer 161 and a second support top layer 162 spaced apart. Along the direction from the outer side 130 to the inner side 120 of the air column, the inner side 120 includes a first inner layer 121 and a second inner layer 122 spaced apart, and the outer side 130 includes a first outer layer 131 and a second outer layer 132 spaced apart. The first bottom layer 111, the first inner layer 121, the first support top layer 161, and the first outer layer 131 are connected sequentially, as are the second bottom layer 112, the second inner layer 122, the second support top layer 162, and the second outer layer 132. This double-layer structure, with the spacing between the two layers, provides a buffering and shock-absorbing effect, and also improves the circumferential buffering effect of the placement space 170.

[0040] like Figure 2 As shown, in this embodiment, the air column support bottom layer 140 includes a first support bottom layer 141 and a second support bottom layer 142, and the air column support side layer 150 includes a first support side layer 151 and a second support side layer 152. The first bottom layer 111, the first inner layer 121, the first support top layer 161, the first outer layer 131, the first support bottom layer 141, and the first support side layer 151 are connected in sequence, and the second bottom layer 112, the second inner layer 122, the second support top layer 162, the second outer layer 132, the second support bottom layer 142, and the second support side layer 152 are connected in sequence.

[0041] like Figure 2 As shown, in one embodiment, the cushioning packaging 100 has a double-layer structure, comprising an outer air column layer 180 and an inner air column layer 190. The gap between the outer air column layer 180 and the inner air column layer 190 can provide cushioning and shock absorption, and also improve the circumferential cushioning effect of the placement space 170. Figure 2As shown, the outer layer 180 of the air column includes a first bottom layer 111, a first inner layer 121, a first supporting top layer 161, a first outer layer 131, a first supporting bottom layer 141, and a first supporting side layer 151 connected in sequence. In this embodiment, the connections between different surfaces of the outer layer 180 of the air column are all rounded. The inner layer 190 of the air column is shaped similarly to the outer layer 180 of the air column, as shown... Figure 2 As shown, the inner layer 190 of the air column includes a second bottom layer 112, a second inner layer 122, a second top support layer 162, a second outer layer 132, a second bottom support layer 142, and a second side support layer 152 connected in sequence. The connection between adjacent end faces adopts a rounded transition, and the radius of the rounded corner of the rounded transition is larger than the size of the rounded corner at the connection between the end faces of the outer layer 180 of the air column.

[0042] like Figure 2 As shown, in one embodiment, the cushioning package 100 further includes an air column connecting layer 1100, which connects the first bottom layer 111 and the second bottom layer 112 to connect the inflation column 1110 for constituting the outer air column assembly layer 180 and the inflation column 1110 for constituting the inner air column assembly layer 190, thereby making it easier to inflate the cushioning package 100.

[0043] like Figure 2 As shown, in one embodiment, the cushioning package 100 has an integral structure and includes multiple independent inflatable columns 1110. The inflatable columns 1110 are located at the bottom 110, the inner side 120, and the outer side 130 of the air column. In this embodiment, the cushioning package 100 is composed of multiple independent inflatable columns 1110, which together form the bottom 110, the inner side 120, the top support 160, the outer side 130, the bottom support 140, and the side support 150 of the air column. In this embodiment, all the inflatable columns 1110 are distributed in a ring, and the air passage of each inflatable column 1110 is connected to the same inflation port, thereby facilitating the inflation of the cushioning package 100.

[0044] In this embodiment, the cushioning packaging 100 is made of PA (nylon) co-extruded film material, which is a recyclable material, thus making it more environmentally friendly.

[0045] The cushioning package 100 has an uninflated state and an inflated state. In the uninflated state, each air column 1110 is inflated; in the inflated state, each air column 1110 is inflated. When inflated, the cushioning package 100 has both an unbent state and a bent state. In the unbent state, the outer surfaces of the first inner layer 121 and the first outer layer 131 are coplanar, as are the outer surfaces of the second inner layer 122 and the second outer layer 132. In this embodiment, in the unbent state, the outer surfaces of the outer air column layer 180 and the inner air column layer 190 are coplanar.

[0046] The cushioning packaging 100 provided in the above solution has an inner part 120 and an outer part 130 of the air column connected sequentially to the bottom 110 of the air column. The outer part 130 is located on the outer periphery of the inner part 120 of the air column, and one end of the outer part 130 extends beyond the bottom 110 of the air column, so that the outer part 130 can directly contact the placement surface, taking the ground as an example. This makes the bottom 110 of the air column suspended, thereby improving the shock absorption and cushioning effect of the cushioning packaging 100 and providing better protection for the items in the placement space 170.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
