Problems solved by technology

Traditional inflatable valves can meet the needs of automated production, but the structure, size and position of the valve limit the changes in the structure of inflatable products, limit the degree of automation of inflatable products and the inflation efficiency of large-scale products, and are difficult to meet the needs of the current market
[0008] Although the traditional vacuum check valve can meet different levels of vacuum requirements, the processing of the check valve is complicated, and the combination of the check valve and the bag body is difficult to realize automatic production

Embodiment 1

[0045] The setting of the new air valve can make the distribution of the air passage and the direction of the air passage in the same structure without any restrictions. The position of the air valve can also be set separately according to the characteristics of the air column. The inflatable structure under the new inflatable check valve The tile map of the body is as follows Figure 10a As shown, the schematic diagram of three-dimensional molding is shown in Figure 10b shown.

Embodiment 2

[0047] In actual packaging applications, the packaging of a product often requires a combination of different sizes / structures of inflatable cushioning materials. In traditional production methods, only a single size / structure of cushioning materials can be produced in one batch. At the same time, the limitation of raw material specifications leads to the production of small-sized products, which will lead to more waste of layout. Such as Figure 11 As shown, in the production of inflatable materials in the application of the new air valve, the production of materials of different sizes and the imposition between different structures can be realized at the same time, so that the production rate of raw materials is improved, and the processing is convenient and efficient.

Embodiment 3

[0049] The distribution of the new gas check valve in the gas chamber structure and the change of the gas chamber structure

[0050] The new gas check valve is small in size and symmetrical in structure along the center, and can be distributed at any position where an inflatable unit can be formed to form an inflatable buffer according to application requirements. The distribution of the new gas check valve on the air chamber buffer structure can determine the structural shape and density of the gas chamber buffer structure, thereby determining the load capacity and buffer function of the air chamber buffer structure. Such as Figure 12 In the shown air chamber structure, the air chamber unit with a check valve is combined with the non-inflatable airtight unit, and the distribution position and size density of the air chamber unit in the buffer body are more flexible.

Abstract

The invention discloses a gas check valve and application thereof to a packaging bag. The gas check valve is composed of a thin film A, a thin film B and a layer of soft plastic thin film. The thin film A is a main material of a gas chamber structure or a thin film material attachable to the main material of the gas chamber structure. The soft plastic thin film is fixed between the thin film A andthe thin film B, and the soft plastic thin film is combined with the film thin A through the thin film B. Air channels are separately formed in or between the thin film A and the thin film B.

Description

technical field [0001] The invention relates to the technical field of packaging, and more specifically relates to a gas check valve and its application in an air chamber packaging structure. Background technique [0002] A valve is a device or component that can cut off, regulate, divert, prevent backflow, or obtain pressure stabilization, diversion, or overflow pressure relief regulation for liquid, air, or solid loose matter in a fluid. A one-way valve is a valve body that controls fluid to flow in one direction in a specific direction and cannot flow back in reverse. In the field of packaging, the two most direct application forms of the commonly used one-way valve body in terms of gas are: inflation check valve and vacuum check valve. [0003] The application of inflatable check valves in inflatable cushioning materials is represented by the inflatable air chamber structure in the shape of an air column, such as figure 1 As shown, it includes an air column 11, an air ...
