  • Patent number: 7237580
    Abstract: A container filling apparatus includes a fill turret configured to carry a plurality of containers along a first portion of a path as the containers are filled with liquid. A container guide is mounted in fixed relation to the fill turret, the container guide defining an upper guide surface and a lower guide surface spaced apart from the upper guide surface. The upper and lower guide surfaces cooperate to define an edge of a second portion of the path, where the upper guide surface is located to contact a container at a first location and the lower guide surface is located to contact the container at a second location that is spaced apart from the first location. The upper and lower guide surfaces maintain the container in an upright position as the container moves along the edge of the path.

  • Patent number: 6887191
    Abstract: An apparatus for forming the bottom end wall of a carton from a rectangular carton blank having oppositely disposed scored end panels and oppositely disposed unscored end panels includes a rotating mandrel assembly adapted to receive an open-ended carton blank through an open top end of the carton blank, a heating station, a folding station and a sealing station. The folding station has a pair of oppositely disposed reciprocating break fingers to contact and fold inwardly the scored bottom end panels and biasing means for folding inwardly down the unscored bottom end panels. The folding station is rotatable 90° between two functional orientations, a first orientation wherein the break fingers are aligned in the direction of mandrel movement, and a second orientation in which the break fingers are perpendicular to the direction of mandrel movement.
