An embodiment of the utility model provides a fill and cover structure, fill and cover structure and include marginal butt structure. As shown in fig. 1 to 2, the edge abutment structure includes an abutment inflation portion 101 and a support inflation portion 102, one surface of the abutment inflation portion 101 abuts against a side wall of the product, and the other surface opposite thereto is connected to the support inflation portion 102. When aerifing in the structure to the edge butt, the portion 101 is aerifyd to the butt increases to make the butt aerify portion 101 inflation, when receiving external shock, outside object extrudees the butt portion 101 in coordination with the product, and the butt portion 101 of aerifing is when keeping apart outside object and product, and the atress can produce certain deformation, thereby absorbs partial impact force, avoids the product impaired.

Further, the support inflation portion 102 is communicated with the abutting inflation portion 101, and when the inflation is performed, the support inflation portion 102 is also expanded, and the expanded support inflation portion 102 further improves the thickness of the filling cover structure on the basis of the abutting inflation portion 101, so that the cushioning effect is improved, and meanwhile, a foundation is provided for the combined work of the edge abutting structure. It will be appreciated that the abutment plenum 101 is juxtaposed with the support plenum 102, together providing protection to the side walls of the product.

Specifically, the edge butt structure is provided with a plurality ofly, and each edge butt structure is around product lateral wall a week to promote the guard effect. Each edge butt structure can splice, and each edge butt structure after the concatenation forms a whole. Each edge abutting structure is spliced by each supporting inflating part 102, each supporting inflating part 102 encloses a storage space 201, and the product is in the storage space 201. The abutting inflatable portion 101 needs to abut against the side wall of the product, therefore, the abutting inflatable portion 101 is located in the range of the storage space 201, and it can be understood that, since each abutting inflatable portion 101 is located inside the pattern formed by splicing each supporting inflatable portion 102, the perimeter of the position where each abutting inflatable portion 101 is located is smaller than the perimeter of the position where each supporting inflatable portion 102 is located, and in order to ensure the stability of each edge abutting structure combination, the length of the abutting inflatable portion 101 is smaller than the length of the supporting inflatable portion 102.

As shown in fig. 3, in some examples, the abutment plenum 101 is disposed at a first end of the edge abutment structure, and the first end of the abutment plenum 101 is flush with the first end of the support plenum 102, i.e., the edge abutment structure is shaped such that the first end thickness is greater than the second end thickness. Specifically, a first end of each edge abutment structure abuts a surface of an adjacent support plenum 102, i.e., a second end surface of an adjacent edge abutment structure, thereby forming an end-to-end connection of each edge abutment structure, enclosing each edge abutment structure in a relatively closed figure.

In particular, when the package is prismatic, the set of edge abutment structures is provided with four, the four edge abutment structures approximately forming a rectangular structure after inflation, each side of the rectangular structure being composed of two adjacent edge abutment structures, i.e. the thickness of the second end of the edge abutment structure corresponds to the sum of the lengths of the edge abutment structures and the side length of the rectangular structure. The tip of adjacent marginal butt structure overlaps the setting, and overall structure is more stable under the stress state, makes each marginal butt structure atress in coordination, promotes the bradyseism effect.

In some examples, the abutting inflation portion 101 includes multiple first inflation layers that can accommodate different amounts of inflation required for different products or different package shapes. Specifically, when the gap between the product and the package is large, a large number of first inflation layers can be used, so that the thickness of the abutting inflation part 101 is fully increased, and the position stability of the product in the transportation process is ensured; when the space between the product and the package is small, a smaller number of first inflatable layers is activated, so that the thickness of the abutting inflatable part 101 is smaller and adapted to the size of the space. It will be appreciated that the first inflatable layers are arranged in a stacked configuration, with the first inflatable layers being in communication with one another to facilitate deployment of all of the first inflatable layers. Or each first inflatable layer may be independently positioned to facilitate deployment of a particular first inflatable layer. Specifically, two first inflation layers are provided against the inflation portion 101.

In some examples, the sidewall of the first pneumatic layer includes a first sloped portion 103, a first raised portion 104, the first sloped portion 103 being angled with respect to the first raised portion 104. Specifically, the first inclined portion 103 has a gradually decreasing cross section, i.e., the first inclined portion 103 gradually shrinks inward from the first protruding portion 104. Further, adjacent first inflatable layers are connected through the first inclined portion 103, and each first protruding portion 104 is far away from the connection of the adjacent first inflatable layers, so that a concave area is formed on the side wall of the abutting inflatable portion 101. When the abutment inflatable portion 101 is deflated, the side walls of the abutment inflatable portion 101 are retracted inwards due to the existence of the recessed area, facilitating the storage of the abutment inflatable portion 101; when the abutting inflatable portion 101 is inflated, the provision of the recessed region causes the first raised portion 104 to abut against the adjacent edge abutting structure, improving the connection stability.

Further, adjacent second pumping layers are connected by a second slope part 105, so that a concave region is formed on the sidewall of the support pumping part 102. When the support inflatable portion 102 is deflated, the side walls of the support inflatable portion 102 contract inward, facilitating the storage of the support inflatable portion 102; when the support plenum 102 is inflated, the provision of the recessed area causes the second raised portion 106 to abut the adjacent edge abutment structure, improving connection stability.

The angle of the second protrusion 106 is set to be a cambered surface, so that the stress at the angle is dispersed, and the durability is improved. Specifically, the junction of the second protruding portion 106 and the second inclined portion 105 is set to be an arc surface, and the angle of the second protruding portion 106 away from the second inclined portion 105 is also set to be an arc surface.

In some examples, an inflation port is provided on the edge abutment structure through which gas enters the edge abutment structure, thereby inflating the edge abutment structure. When the first inflation layers and the second inflation layers are communicated with each other, one inflation opening is arranged; when the first inflatable layers and the second inflatable layers are independently arranged, inflation ports are respectively arranged on each first inflatable layer and each second inflatable layer.
