Abstract

A system is provided for the detection of contaminant particulates in closed containers, that system having a plurality of system components susceptible to degredation during the manufacture of container contents and filling of the closed containers, the system components susceptible to degradation comprising a radio opaque composition of matter; an x-ray source disposed proximate to a path of the closed container in a production line; an x-ray image intensifier whereby x-rays from the x-ray source are collected and an image is generated; a ccd camera whereby the x-ray image is digitized; a contaminated container rejection mechanism whereby closed containers having x-ray images with radio opaque portions are rejected as contaminated and removed from the production line.

Claims (15)

1. A system for the detection of contaminant particulates in closed containers, said system comprising:

a plurality of solid polymer gaskets comprising radio-opaque, barium-containing polymerized fluorinated hydrocarbon elastomers disposed in a production line of container contents and susceptible to degradation during the manufacture of said container contents and filling of said closed containers;

an x-ray source disposed proximate to a path of said closed container in a production line;

an x-ray image intensifier whereby x-rays from said x-ray source are collected and an image is generated;

a ccd camera whereby said x-ray image is digitized;

a contaminated container rejection mechanism whereby closed containers having x-ray images with radio opaque portions are rejected as contaminated and removed from said production line.

2. The system of claim 1 , wherein said barium is barium sulfate.

3. The system of claim 1 , wherein said radio opaque substance comprises a finely divided powder.

4. The system according to claim 3 , wherein said finely divided radio opaque powder comprises barium sulfate and reduced iron.

5. A method for the detection of contaminants in closed containers in a production line, said method comprising:

using radio opaque tracer disposed in solid polymerized fluorinated hydrocarbon gaskets disposed in a production line;

exposing said closed containers to x-ray radiation from an x-ray source;

creating an x-ray image of contents of said closed containers;

analyzing said x-ray image for radio opaque regions indicative of fragments of said gaskets;

rejecting closed containers having a high degree of radio opacity in at least one portion of said x-ray image.
