The container cannot meet the transfer requirements of materials that need to be sealed and stored at normal pressure, transferred to a low-pressure environment, opened the container for process treatment, and then returned to sealed and stored at normal pressure.
[0003] In order to overcome the above defects, material transfer devices have appeared on the market, including storage containers with valves installed at the inlet and outlet respectively. A vacuum pump is connected to the storage container through a connecting pipe to achieve the purpose of transferring materials in isolation from air. This equipment occupies a large space and has a high cost of use.
[0004] Therefore, it is urgent to provide a material transfer container to overcome the above-mentioned defects. Utility Model Content

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A material transfer container, comprising:
[0008] The outer cavity (1) is a receiving structure with an opening at one end;
[0009] The sealing kit (2) comprises: a pressure-resistant container (21) fixed in an outer cavity by a mounting plate (24), a pressure relief device (22) installed on one side of the pressure-resistant container (21) and penetrating the outer cavity, and a sealing cover (23) covering the opening of the outer cavity and capable of enclosing the pressure-resistant container (21) into a sealed space by its own weight;
[0010] The ejection mechanism (3) is installed in the outer cavity (01) and beside the sealing kit (2). Under normal pressure, the ejector rod (31) is compressed and retracted, and under negative pressure / vacuum, the telescopic airbag (32) is expanded to lift up the ejector rod (31) and the sealing cover (23).
[0011] Preferably, the ejection mechanism (3) comprises: an assembly connector (33) assembled on the mounting plate (24), the telescopic airbag (32) installed in the assembly connector (33), and a connecting plate (34) arranged at one end of the telescopic airbag (32) and fixing the ejector rod (31).
