The machine provides controlled mechanism to apply a lid or cover from a stack over the opening of a container filled with liquid such as paint and move it to a subsequent station whereat the lid is pressed firmly by a pneumatically operated press onto the filled container on which it has been deposited. The lids are supported in a stack over the lid applying station of the machine and are released one by one from the stack into succeeding containers by a pneumatically actuated hold-back device whose release and hold-back positions are dependent upon positions of containers moved to and beyond the lid applying station to the subsequent lid pressing station. All controls are by pneumatic devices which are essential especially when the containers are to be filled with inflammable liquids. The containers are filled prior to deposition of lids thereon as by the filling machine described in U.S. Pat. No. 3,702,625. |
