  • Patent number: 4610345
    Abstract: Method and apparatus in which dispenser cap assemblies of the type having a trigger-type pump cap and a dip tube are fed to a generally cone-shaped drum which rotates about a vertical axis and carries compartments within which the cap assemblies are moved in a generally spiral outward direction while moving axially downwardly to be oriented vertically, with the cap below the dip tube, the cap assemblies then being transferred to a turnover wheel which rotates about a horizontal axis so that the cap assemblies are inverted to re-orient each cap assembly into a position where each dip tube depends vertically downwardly from the respective cap, the cap assemblies then being passed to a horizontal conveyor for advancement to a discharge point where the cap assemblies are presented serially in a prescribed alignment and orientation, at a relatively high rate, for capping operations.
