Precision lid fit filling machine

摘要

The specification discloses a method and apparatus for accurately positioning a lid of a series of lids above a container flange in preparation for the heat sealing operation. The apparatus is designed to maintain the production rate of prior art filling and packaging machines while still precisely locating a lid such that little or no overhang of the lid relative to the flange of a container occurs. This is achieved by providing a start and stop type conveyor with individual conveyor plates provided with alignment lugs for urging the flange of a container and a lid into alignment. The resulting product is less vulnerable to lid damage and hence is more presentable when served to the consumer. This system is particular valuable in the packaging of individual creamer containers.
