Abstract:
A telescoping filling head comprising:a nozzle block including a first and second surface, a passage through said nozzle block from the first surface to the second surface, and at least one inlet into the nozzle block which opens into the passage and which permits the introduction of a product flow into the passage; a nozzle unit comprising two portions, an inner nozzle and nozzle holder, wherein the nozzle unit passes through the passage and extends out of the first and second surfaces of the nozzle block, wherein the inner nozzle includes an inner nozzle tip and a driving portion, wherein the inner nozzle tip is hollow and includes walls and a closed base end, wherein the walls include one or more apertures adjacent the base end; and wherein the nozzle holder is adapted to transmit a driving force to the inner nozzle; a telescoping unit extending from the second surface of said nozzle block, said telescoping unit including: an outer nozzle which includes first and second ends, wherein the outer nozzle is hollow, wherein the first end of the outer nozzle is open and adapted to sealingly connect to the second surface of the nozzle block, wherein the second end of the outer nozzle includes an opening; and a telescoping nozzle which includes first and second ends, and which is hollow and open at both ends, wherein the telescoping nozzle is adapted to slide back and forth sealingly within the opening in the second end of the outer nozzle, wherein the second end of the outer nozzle is adapted to prevent the first end of the telescoping nozzle from exiting the opening in the second end of the outer nozzle; and a first biasing device which biases the nozzle holder away from the first surface of the nozzle block; and a second biasing device which biases the telescoping nozzle away from the second surface of the nozzle block.
