Abstract:
An apparatus for filling a preformed cell cavity positioned between a first substrate and a second substrate with a cell filling fluid, said apparatus comprising the combination of:(a) said preformed cell cavity;(b) a first member for forming a first evacuation cavity between at least a portion of an outer surface of said first substrate and at least a portion of said first member, said first member having a first pressure control orifice for communicating with said first evacuation cavity, wherein said portion of said outer surface of said first substrate substantially conforms to a perimeter defined by said preformed cell cavity;(c) a second member for forming a second evacuation cavity between at least a portion of an outer surface of said second substrate and at least a portion of said second member, said second member having a second pressure control orifice for communicating with said second evacuation cavity, wherein said portion of said outer surface of said second substrate substantially conforms to said perimeter defined by said preformed cell cavity;(d) a dispensing system for dispensing the cell filling fluid into said preformed cell cavity via a dispensing inlet for communicating with said cell cavity;(e) a vacuum system for reducing a pressure in each of (i) said cell cavity via an evacuation outlet for communicating with said preformed cell cavity, (ii) said first evacuation cavity via said first pressure control orifice and (iii) said second evacuation cavity via said second pressure control orifice.
