Abstract
Bottles to be cleaned are fed in succession to an infeed starwheel from which they are transferred to a rotor on which there are circumferentially spaced apart cam operated bottle inverting devices that grip the bottles and invert them with their mouths over a nozzle that injects cleaning fluid into them. The gripping devices have on them gripper fingers which are V-shaped and are molded, respectively, of a resilient and deflectable synthetic resin such as a polyamide. There is an upper gripper having finger tips spaced apart to engage the neck of a bottle and a lower gripper having finger tips or the like that grip or support the cylindrical body of the bottle.
