THE METHOD OF DETERMINING WHEN THE VACUUM IN A CONTAINER FALLS BELOW A PREDETERMINED LEVEL WHERE THE CONTAINER INCLUDES A FLIP PANEL THAT ASSUMES A CONCAVE CONFIGURATION WHEN THE VACUUM IS SATISFACTORY AND A CONVEX CONFIGURATION WHEN THE VACUUM IS UNSATISFACTORY, WHICH METHOD COMPRISES MOVING CONTAINERS CONTINUOUSLY IN SUCCESSION PAST AN INSPECTION STATION, DIRECTING A FIRST BEAM OF RADIANT ENERGY DIRECTLY INTO THE FLIP PANEL OF A CONTAINER AS IT REACHES THE INSPECTION STATION, CAUSING SAID FIRST BEAM TO BE REFLECTED BY SAID FLIP PANEL UPWARDLY INTO A PERDETERMINED AREA, CAUSING A PORTION OF SAID BEAM TO BYPASS SAID AREA WHEN THE VACUUM IN THE CONTAINER IS UNSATISFACTORY AS EVIDENCED BY A CONVEX CONFIGURATION OF THE FLIP PANEL, INTERRUPTING SAID BYPASSED PORTION OF SAID FIRST BEAM TO CREATE A PLURALITY OF PULSES OF RADIANT ENERGY, DIRECTING A SECOND BEAM FO RADIANT ENERGY IN THE PATH OF SAID CONTAINERS IN SAID INSPECTION STATION, CAUSING EACH CONTAINER TO INTERRUPT SAID SECOND BEAM AS IT REACHES THE INSPECTION STATION, CREATING A PULSE OF PREDETERMINED TIME INTERVAL IN RESPONSE TO THE INTERRUPTION AND RE-ESTABLISHMENT OF THE SECOND BEAM AND REJECTING THE CONTAINER WHEN THE PLUSES CREATED BY INTERRUPTING THE BYPASSED PORTION OF THE FIRST BEAM OCCUR DURING THE TIME INTERVAL OF THE PULSE CREATED BY INTERRUPTION OF THE SECOND BEAM.
