    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.

  • Plastic pour-spout and container
    Patent number: 5667111
    Abstract: A novel container having a plastic pour spout is provided, the container carrying a pour spout having a 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 are folded relative to the platform for insertion into an unerected carton. Following insertion, the panels again relax along the hinge-line and 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.
