ABSTRACT:
A technique is described by which a predetermined amount by weight of ground coffee can be packaged into a container while the coffee density may vary within a range. The amount of ground coffee is supplied into a container along a feed path to fill the container and form a column that extends above the upper rim of the container. The ground coffee is compressed to a predetermined head level by compressing a region around the feed path while leaving a small column of uncompressed coffee. In another embodiment, the volume of the container is expanded during compression by outwardly deforming a container end. This enables the stiffening of the ground coffee to support a smooth unbeaded outer wall after vacuum packing without paneling effects.
