Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
119 words
A method for inspecting recovered beverage containers and for distinguishing containers with beverage residue therein from containers with contaminates therein which comprises the steps of: selecting and storing a predetermined color corresponding to the color of the beverage residue in the container, measuring the area of the selected color of beverage residue in a bottom region of the container, determining whether or not the size of the measured area of the color representing beverage residue is within a predetermined range, and distinguishing the beverage containers in accordance with the results of the determining step, the presence of a measured area of the color of the beverage residue within said predetermined range indicating the absence of contaminates within a container.
Claim 2
Independent Claim
