Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
149 words
The method of attaching a pLastic bail-type handle to aligned outwardly projecting pins on a plastic bottle, the pins having enlarged heads with tapered extremities and neck portions of reduced diameter, each depending arm of the bail-type handle having an aperture of a size to fit the neck portion of the pin and normally smaller than the enlarged head portion thereof, said method including the steps of: a. positioning a plastic bottle within a restraining zone; b. spreading the depending arms of the bail-type handle and engaging the apertures in said arms with the tapered extremities of said pins; c. applying adequate force to the extremities of the spread depending arms of the bail-type handle to force said arms over the enlarged head portions of said pins and onto the reduced neck portions thereof, and applying oscillatory movement to said bail-type handle simultaneous with the application of engaging force.
Claim 2
Independent Claim
149 words
The method of attaching a pLastic bail-type handle to aligned outwardly projecting pins on a plastic bottle, the pins having enlarged heads with tapered extremities and neck portions of reduced diameter, each depending arm of the bail-type handle having an aperture of a size to fit the neck portion of the pin and normally smaller than the enlarged head portion thereof, said method including the steps of: a. positioning a plastic bottle within a restraining zone; b. spreading the depending arms of the bail-type handle and engaging the apertures in said arms with the tapered extremities of said pins; c. applying adequate force to the extremities of the spread depending arms of the bail-type handle to force said arms over the enlarged head portions of said pins and onto the reduced neck portions thereof, and applying oscillatory movement to said bail-type handle simultaneous with the application of engaging force.
