Abstract
Abstract A flip-top dispensing container for flowable solid materials includes an improved pour spout and a handle element for automatically lifting the flip-top when the container is dispensed. The container is prepared from two cut and scored paperboard blanks to form an outer container portion and an inner insert portion. The flip-top of the container is formed in the top of the outer container portion from portions of three contiguous outer container body panels and a part of the top closure at one end of the container. The improved pour spout is formed from the panels of the inner insert portion by extendable wing elements foldably attached thereto. The wing elements and one panel of the insert are provided with diagonally oriented score lines which enable the wing elements to be folded inwardly to provide improved flow control during dispensing. The handle element is located between the top closure flaps of the outer container so that one end thereof is attached to the flip-top portion of the container. Thus once the container is opened, the flip-top is automatically lifted into its dispensing position when the container is lifted by its handle.
