  • Carton with pour spout
    Patent number: 6158654
    Abstract: A carton blank has a generally half-circular line of perforation extending in the outer top panel and an end panel joined to the outer top panel at a hinge line. The line of perforation has a reduced radius portion which forms a lip in the assembled carton which acts as a closure for the spout. The end panel has an outside free edge not aligned with the main panel top edge so as to expose a portion of the inner top panel thereby allowing for joinder of the inner and outer top panels with fewer glue lines.
