Abstract
Apparatus for cleaning open-mouthed cylindrical containers has a plurality of pot assemblies mounted on a turntable rotatable to move each pot assembly past an unloading station for discharge of containers from the pot assemblies and a loading station for insertion of containers into the pot assemblies. Each pot assembly comprises a body co-operating with a lid to define a cavity for reception of a container, the cavity having a shape corresponding approximately to that of the container and having a size such that the container subdivides the cavity into two chambers in which the walls of the cavity are spaced close to the inside and outside surfaces of the container. Cam rollers on each pot assembly co-operate with cam tracks, upon rotation of the turntable, to open the lid immediately prior to passage past the unloading station and to close the lid immediately after passage past the loading station. During passage between the loading and unloading stations cleaning liquid is circulated through the chambers, the liquid flowing along the inside and outside surface of the container to clean the surfaces. The liquid flows at high speed due to the small volume of the chambers. Rinsing…
