Abstract: The vessel portion of a gas-tight container suitable for packaging fresh foods is produced as a composite of paperboard and polymer film.  A pair of folded paperboard blanks, pre-cut and pre-formed, are inserted into the opposite halves of split mold elements to a blow molding machine. Vacuum orifices in each mold half unit temporarily secure the position of a respective paperboard blank.  The paperboard lined mold halves are closed upon a hot, extruded parison of malleable polymer leaving an end portion of the parison tube projecting from the closed mold unit.  A fluid conducting needle penetrates this projected end portion to inflate the parison with an appropriate blowing gas.  Such inflation expands the malleable polymer, seamlessly and creaselessly, into the internal corners and crevices of the folded paperboard blanks.  Following chilling, the mold unit is opened and the pair of paperboard blanks are ejected as a singular unit, joined by a molded flange portion of the continuous polymer film.  Finally, the two polymer coated paperboard vessels are separated by trimming about the flange.

Inventor: ROUNBEHLER DAVID P
IPC: G01N30/74
Filed: 1991-03-08
Granted: 2002-09-17
Abstract: Disclosed are a method and apparatus for high speed, selective detection of vapors of specific compounds, particularly nitrogen-containing compounds, utilizing a bypass branch and high speed gas chromatography for improved selectivity and sensitivity of detection. A system with two gas chromatographs (GC's) alternating in series with two pyrolyzers provides two time intervals of detection in a downstream detector, with the second time interval containing signals delayed and further separated relative to signals from the first time interval. The bypass branch, in diverting a portion of the flow of gas samples from passage through the second gas chromatograph and second pyrolyzer, avoids interferences in the first time interval of detection from non-GC-retained compounds decomposed in the second pyrolyzer.
