A particle-free dockable interface with an interlocking latch is disclosed for linking together two spaces each enclosing a clean air environment and preventing the opening of the interface without the presences of two mating system components. The interface comprises interlocking doors on each space which fit together to trap particles which have accumulated from the dirty ambient environment on the outer surfaces of the doors. The interlocking latch is comprised of a latch spring and latch foot assembly coupled to a first one of the two clean air spaces and a mating door pull and port latch assembly coupled to the second of the two clean air spaces. The latch foot, door pull, and port latch assemblies are constructed so that interlock doors cannot be opened unless the first and second clean air spaces are properly aligned and mated.

An interface between first and second containers comprising: alignment means for orienting the first container in a fixed position relative to the second container; a first door for independently sealing the first container; a second door for independently sealing the second container; said first and second doors each having a mating outer surface of substantially equal exterior dimensions, so that substantially all contamination which has accumulated on the exterior surface of the doors when the containers are separated will be trapped between said doors when the containers are positioned together with said alignment means; elevator means coupled to said doors for transporting said doors while coupled together at their mating outer surfaces into said containers as a single unit; and interlock means coupled to the first and second doors for inhibiting the opening of the first door except when the first and second containers are mated in the alignment means, said interlock means having port latch means coupled to the first container for maintaining the first door in a closed position when the port latch means is in a closed position and for permitting the first door to open when the port latch means is in an opened position, door pull means coupled to the first container for transporting the port latch means from the opened position to the closed position of the port latch means, said door pull means being adapted so as not to independently transport the port latch means from the closed position to the opened position of the port latch means, and latch foot means coupled to the second container for engaging the port latch means and door pull means so that together the door pull means and the latch foot means can transport the port latch means from the closed position to the opened position of the port latch means.
