Abstract
A folding pour spout, particularly, for detergent cartons. The spout is formed from a spout blank preferably comprising a single thin sheet of plastic. The spout blank includes a first spout-forming panel having a pull tab, a second spout-forming panel including notches and a panel for attachment to a carton. The reduced thickness of the spout blank facilitates manufacturing of the carton.
