An insert with an upwardly projecting protuberance proximate one end is inserted into an open container. The open container is conveyed continuously in a downstream direction with a container conveyor with the container opening upwardly. The insert is held above the conveyor at an insertion station by supporting a downstream portion of the insert: the protuberance bearing end of the insert being the upstream end of the insert. A pusher finger is driven downwardly against an upstream portion of the insert at a downstream side of the protuberance in order to push the upstream portion of the insert downwardly into the container. The upstream portion of the insert is pushed against an inside surface of the container with the pusher finger while the container is conveyed underneath the insert. Simultaneously, the support is removed from the downstream portion of the insert. With the pusher finger abutting the downstream side of the protuberance, frictional engagement between the insert and the container is overcome as the container is conveyed underneath the insert. The pusher finger is retracted at the conclusion of the insertion operation.
