Abstract
A carton formed from a unitary blank of paperboard includes a front panel, a rear panel and side panels joined to the front and rear panels along fold lines. Top and bottom closure flaps are joined to the front and rear panels. A pour spout is defined by one of the panels. The pour spout includes a generally triangular flap joined to the panel along an angled fold line. The triangular flap or area includes a lateral edge to which a closure tab or glue flap is joined. A dust flap is joined to a top edge of the triangular flap along a fold line. The dust flap defines a curved edge and a notch. The notch is positioned to engage a top edge of one of the panels to hold the spout in an open position. Glue is applied to one of the panels to engage the closure tab or glue flap to initially hold the spout in a closed position.
