ABSTRACT:
A pressurized sealable transportable container (100) stores at least one workpiece (138) and has a substantially parallelepipedic-shaped cassette reservoir (123). The container has a box-shaped housing (102) with a main access opening (104) on the front lateral face and protective shells to protect the housing top (143) and bottom (144) surfaces. A door (124) mates with the main access opening to define a sealable interior space (103). The housing has a gas injection valve (124) adapted for connection to a compressed ultra pure neutral gas supply installation (700) to establish a determined static first or nominal pressure p within the interior space having a positive differential pressure .DELTA.p with respect to the outside ambient. A support (108) firmly and accurately maintains the workpiece within the interior space.
