  • Patent number: 7331622
    Abstract: A carrier is provided for use with containers including handles. The container carrier comprises a flexible platform having a perimeter, a longitudinal axis, and an opening, with a portion of the platform at least partially defining the opening and adjacent the closest side of the perimeter of the platform so as to form a handle including a strap. The strap is located such that the longitudinal axis of the platform transverses the strap. Recessed portions are located in the perimeter of the platform, and the recessed portions are located on opposite sides of the longitudinal axis of the platform that transverses the strap. Each recess portion receives a container handle of the adjacent containers. The opening is sized so as to receive at least one of a user's fingers for lifting and transporting the containers.

  • Patent number: 6164432
    Abstract: An apparatus for feeding articles, comprising: a surface; a plurality of conveyor belts spanning the surface; a motor driving the conveyor belts for transporting the articles along the surface; a barrier bar positioned above the surface for preventing further transport of the articles along the surface; and an actuator connected to at least one of the conveyor belts. The actuator raises at least a first portion of the conveyor belt a distance above the surface and lowers the conveyor belt back to the surface. Raising the actuator propels one of the articles past the block. The article feeding apparatus can be one component of a larger article handling system.

  • Patent number: 6044959
    Abstract: An apparatus for staging or pitching articles on a conveyor system. Arranged on a supporting table is a first set of belts covering approximately one-half of the length of the table travelling at a high rate of speed, and having a high function surface. Arranged on the second half of the table and traveling in the same direction are slower belts having a low friction surface. Laterally, preferably outside the first and second belts are two or more belts traveling at a slower speed, having a low friction surface and carrying projection away from the surface of the table to align articles during the transfer from high to low speed. Preferably, the table is a plenum and suction draws articles to the surface.

  • Patent number: 6029865
    Abstract: A novel container having an internal pour spout is provided, the sealed container carrying a pour spout having a central platform, a first side panel connected by hinge to the platform on a first side and a second panel connected by hinge to the platform on a second side, the two side panels having a substantially triangular shape. The hinged connection of the panels to the platform permit each pour spout to be provided in a flattened configuration in which the side panels permit subsequent processing of the flattened carton stock. When the carton is folded, the panels move passively in response to the carton folding steps and assume an assembled configuration as the carton is assembled.
