Abstract
Abstract A container support is provided in a capping machine including a platform having an upwardly open recessed seat in it and a spring supported depressible pedestal in the seat, which in its raised position has its top surface substantially coplanar with the upper surface of the platform so that the container can be moved laterally into and out of position on the platform, and in its depressed position permits seating of the container in the seat for support of the lower peripheral portions of the container during capping.
