At least one horizontal post has one distal end fixedly attached to the baffle, and the top edge of the first sheet of the package bag is mounted around the horizontal post. A pushing member has a vertical section slidably mounted around the horizontal post for urging the first top edge of the first sheet of the package bag to abut on the baffle.
